[0018] Furthermore, in the conveying device, the first blocking mechanism also includes a third driving member, which is located at the output end of the first conveying structure. The second driving member is located at the third driving member.

When a material sheet needs to be sampled for inspection, the first conveying structure stops feeding the material sheet along the X-direction, allowing the material sheet to remain stationary on its conveying surface. The first conveying structure then descends along the Z-direction until its conveying surface is lower than that of the second conveying structure, so that the material sheet rests on the second conveying structure. The second conveying structure then feeds the material sheet along the Y-direction to the third conveying structure, which then feeds the material sheet until it is completely exposed outside the housing, allowing for manual removal for sampling inspection. After sampling inspection, the third conveying structure feeds the material sheet back to the second conveying structure, and the first conveying structure rises and lifts the material sheet, returning both to their initial height so that feeding can continue along the X-direction.

It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application. Unless further described, elements, structures, and features in one embodiment may be advantageously combined with other embodiments.

[0034] It should be noted that when a metastructure is referred to as "fixed to" or "set on" another metastructure, it can be directly on or indirectly on that other metastructure. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0035] The terms “length”, “width”, “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inner”, “outer”, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0036] Please see Figure 1The conveying device provided in this application includes a housing 10, a first conveying structure 20, a second conveying structure 30, and a third conveying structure 40. The first conveying structure 20 is disposed within the housing 10; the second conveying structure 30 is disposed within the housing 10 and located below the first conveying structure 20. The first conveying structure 20 can move along the X direction (e.g., ...). Figure 1 Conveyed in the direction indicated by the middle arrow X), and can also be transported along the Z direction (e.g., Figure 1 The first conveying structure 20 moves in the direction indicated by the middle arrow Z. During its descent along the Z direction, it can pass through the second conveying structure 30, so that the conveying surface of the first conveying structure 20 is lower than the conveying surface of the second conveying structure 30. The conveying surface of the third conveying structure 40 is exposed outside the housing 10 and is located on the same plane as the conveying surface of the second conveying structure 30. The second conveying structure 30 and the third conveying structure 40 can move along the Y direction (as shown by the middle arrow Z). Figure 1 (In the direction indicated by the middle arrow Y) conveying. The conveying surface heights of the second conveying structure 30 and the third conveying structure 40 are designed for easy manual removal of the sheet material. During normal sheet material conveying, the sheet is placed on the conveying surface of the first conveying structure 20, which conveys the sheet along the X direction. When a sheet needs to be inspected, the first conveying structure 20 stops conveying the sheet along the X direction, leaving the sheet stationary on its conveying surface. The first conveying structure 20 then descends along the Z direction until its conveying surface is lower than that of the second conveying structure 30, allowing the sheet to rest on the second conveying structure 30. The second conveying structure 30 then conveys the sheet along the Y direction to the third conveying structure 40, which then conveys the sheet until it is completely exposed outside the housing 10, facilitating manual removal for inspection. After inspection, the third conveying structure 40 conveys the sheet back to the second conveying structure 30, and the first conveying structure 20 rises and lifts the sheet, restoring both to their initial heights so that conveying can continue along the X direction. With this design, when random inspection is required, personnel can directly remove the material pieces from the third conveying structure 40 for random inspection, thereby effectively improving the efficiency of random inspection.

[0037] The third conveying structure 40 can be independently disposed outside the housing 10 or disposed inside the housing 10. This embodiment does not limit it. This embodiment takes the third conveying structure 40 disposed inside the housing 10 with only the conveying surface exposed outside the housing 10 as an example.

[0038] In some embodiments, the conveying device also includes an operation panel 130, which has six buttons, specifically including an EMO button, a start button, a finish button, a sheet removal button, a grating reset button, and a sampling button. The EMO button is used to stop the equipment in an emergency; pressing it cuts off the power to ensure personnel safety. The start button controls the safety grating 120 to prevent alarms when it detects an object. The finish button returns the sheet to the housing 10. The sheet removal button, when pressed, disables the on-site detection sensor of the third conveying structure 40 when personnel need to remove the sheet from the detection position. The grating reset button controls the reset of the safety grating 120. The sampling button initiates the material discharge action.

[0039] Please see Figures 2 to 6 In some embodiments, in order for the first conveying structure 20 to convey along the X direction, for the second conveying structure 30 to convey along the Y direction, and for the first conveying structure 20 to pass through the second conveying structure 30 during its descent along the Z direction, the first conveying structure 20 includes a first driving assembly and a plurality of spaced roller groups 25. The first driving assembly can drive the plurality of roller groups 25 to convey along the X direction, and the plurality of roller groups 25 are used to convey material sheets. The second conveying structure 30 includes a second driving assembly and a plurality of spaced first pulley groups 34, and the plurality of first pulley groups 34 and the plurality of roller groups 25 are arranged alternately in sequence. The second driving assembly can drive the plurality of first pulley groups 34 to convey along the Y direction, and the plurality of first pulley groups 34 are used to convey material sheets. During the descent of the first conveying structure 20 along the Z direction, the plurality of roller groups 25 can pass through the plurality of first pulley groups 34. This design ensures that the multiple roller sets 25 do not interfere with the multiple first pulley sets 34 when they are raised and lowered. When the conveying surface of the roller set 25 is lower than the conveying surface of the first pulley set 34, the material falls onto the first pulley set 34. At this time, the material can be transported along the Y direction and flow out of the housing 10 for inspection.

[0040] In some embodiments, in order to drive multiple roller sets 25, the first driving assembly includes a first driving member 21, a helical gear 22, a first connecting rod 23 and multiple magnetic transmission members 24. The first driving member 21, the helical gear 22 and the first connecting rod 23 are sequentially connected for transmission, and the multiple magnetic transmission members 24 are spaced apart from the first connecting rod 23. Each magnetic transmission member 24 is connected to the roller set 25 in a one-to-one correspondence.

[0041] Furthermore, the magnetic transmission component 24 includes magnetic wheels 241 and non-contact magnetic rings 242. Multiple magnetic wheels 241 are spaced apart and connected to the first connecting rod 23, while multiple non-contact magnetic rings 242 are connected one-to-one to the roller assembly 25. The non-contact magnetic rings 242 drive the roller assembly 25 to roll under the magnetic force of the magnetic wheels 241. Using a non-contact magnetic structure for drive reduces wear, extends lifespan, simplifies the structure, improves reliability, provides overload protection, offers flexible layout, and reduces vibration and noise.

[0042] The roller assembly 25 includes rollers 251 and 252. A non-contact magnetic ring 242 is disposed on roller 251, and roller 252 is also disposed on roller 251. The non-contact magnetic ring 242 drives roller 251 to rotate, and roller 251 drives roller 252 to roll, thus conveying the material sheet. Preferably, roller 252 is made of a composite material of ultra-high molecular weight polyethylene and carbon fiber. With this design, because the composite material of ultra-high molecular weight polyethylene and carbon fiber has antistatic properties, if the material sheet itself carries static electricity, the roller 252 can discharge the static electricity upon contact.

[0043] Please see Figure 4 In some embodiments, the conveying device further includes a first blocking mechanism 50, which includes a second driving member 51 and a first blocking member 52. The second driving member 51 is located at the output end of the first conveying structure 20, and the first blocking member 52 is located on the second driving member 51. The second driving member 51 can drive the first blocking member 52 to descend along the Z direction to avoid the material sheet, or to rise to block the material sheet. With this design, when the first conveying structure 20 is normally conveying the material sheet, the second driving member 51 drives the first blocking member 52 to descend along the Z direction to avoid the material sheet. When the first conveying structure 20 stops conveying the material sheet along the X direction, the first blocking member 52 rises to block the material sheet to prevent it from falling from the first conveying structure 20.

[0044] Furthermore, the first blocking mechanism 50 also includes a third driving member 53, which is located at the output end of the first conveying structure 20. A second driving member 51 is located on top of the third driving member 53. The third driving member 53 can drive the first blocking member 52 to extend along the X direction to avoid the sheet, or retract to move the sheet to a preset position, where the preset position corresponds to the position of the conveying surface of the third conveying structure 40. With this design, the first blocking member 52 can ensure that the sheet stops at this position during sampling, so that the reference edge of the sheet can remain consistent when it is displaced along the Y direction, facilitating the sheet to enter the conveying surface of the third conveying structure 40.

[0045] In some embodiments, the conveying device further includes a deceleration sensor 60 and a position sensor 70 electrically connected to the first conveying structure 20. The deceleration sensor 60 sends a deceleration signal to the first conveying structure 20 when it senses a piece of material, and the first conveying structure 20 decelerates its conveying according to the deceleration signal. The position sensor 70 sends a stop signal to the first conveying structure 20 when it senses a piece of material, and the first conveying structure 20 stops its conveying according to the stop signal. Specifically, when the piece of material moves into the sensing area of ​​the deceleration sensor 60, the deceleration sensor 60 senses the piece of material and sends a deceleration signal to the first driving member 21, and the first driving member 21 decelerates its rotation according to the deceleration signal. When the piece of material moves into the sensing area of ​​the position sensor 70, the position sensor 70 senses the piece of material and sends a stop signal to the first driving member 21, and the first driving member 21 stops its rotation according to the stop signal. This design can prevent the piece of material from colliding with the first blocking mechanism 50 during rapid movement, thus preventing damage to the first blocking mechanism 50.

[0046] Please see Figure 5 In some embodiments, to allow the first conveying structure 20 to rise and fall relative to the housing 10, the conveying device further includes a lifting mechanism 80. The lifting mechanism 80 includes a fourth driving member 81 and a guide member 82. The fourth driving member 81 is disposed within the housing 10 and connected to the first conveying structure 20 to drive the first conveying structure 20 to rise and fall. The guide member 82 is disposed within the housing 10 and connected to the first conveying structure 20 to guide the first conveying structure 20. With this design, the fourth driving member 81 can provide power for the rising and falling of the first conveying structure 20, and the guide member 82 can guide the first conveying structure 20, allowing it to rise steadily.

[0047] The fourth driving component 81 includes a lifting cylinder 811 and a first connecting plate 812. The bottom of the lifting cylinder 811 is located on the housing 10, and the top of the lifting cylinder 811 is connected to the first connecting plate 812. The top of the first connecting plate 812 is connected to the first conveying structure 20. The lifting cylinder 811 is used for driving, resulting in a simple structure.

[0048] The guide members 82 consist of two sets, located on either side of the fourth drive member 81. Each set of guide members 82 includes two linear bearings 821, two guide rods 822, and a second connecting plate 823. The two linear bearings 821 are mounted on the housing 10. The bottoms of the two guide rods 822 are movably mounted on the linear bearings 821, and the tops of the two guide rods 822 are connected to both ends of the first connecting plate 812. The top of the first connecting plate 812 is connected to the first conveying structure 20. This design provides the first conveying structure 20 with synchronized horizontal lifting and lowering, ensuring smooth and stable movement without swaying during ascent and descent.

[0049] In some embodiments, in order to drive multiple first pulley sets 34, the second drive assembly includes a fifth drive member 31, a first synchronous pulley set 32 ​​and a second connecting rod 33. The fifth drive member 31, the first synchronous pulley set 32 ​​and the second connecting rod 33 are sequentially connected in a transmission manner, and the multiple first pulley sets 34 are spaced apart and connected to the second connecting rod 33.

[0050] Furthermore, the conveying device also includes a second blocking mechanism 90, which includes a seventh driving member 91 and a second blocking member 92. The seventh driving member 91 is located at the end of the second conveying structure 30 away from the third conveying structure 40, and the second blocking member 92 is located on the seventh driving member 91. The seventh driving member 91 can drive the second blocking member 92 to move along the Y direction to adjust the position of the second blocking member 92. With this design, on the one hand, the second blocking member 92 can prevent the material sheet from detaching from the second conveying structure 30 during reflow, ensuring that the position of the reflowed product is not deviated; on the other hand, the second blocking member 92 can move along the Y direction to accommodate products of different sizes.

[0051] Please see Figure 7 In some embodiments, in order for the third conveying structure 40 to convey along the Y direction, the third conveying structure 40 includes a sixth driving member 41, a second synchronous pulley group 42, a third connecting rod 43, and a plurality of second pulley groups 44. The sixth driving member 41, the second synchronous pulley group 42, and the third connecting rod 43 are sequentially connected for transmission. The plurality of second pulley groups 44 are spaced apart and connected to the third connecting rod 43. The plurality of second pulley groups 44 convey along the Y direction. The plurality of first pulley groups 34 are used to convey material sheets.

[0052] Furthermore, the conveying device also includes a third blocking member 100 and a fourth blocking member 110. The third blocking member 100 is located at the end of the third conveying structure 40 away from the second conveying structure 30, and the fourth blocking member 110 is located on one side of the third conveying structure 40. With this design, the third blocking member 100 and the fourth blocking member 110 can prevent the material sheet from detaching from the third conveying structure 40.

[0053] In some embodiments, safety light curtains 120 are provided on both sides of the housing 10 corresponding to the third conveying structure 40. With this design, when an object (such as a human limb, tool, etc.) blocks any beam of infrared light, the light curtain will immediately output a signal to trigger the equipment to stop operating, alarm, or activate safety measures, thereby avoiding injury to personnel or damage to equipment.

[0054] The following is a detailed explanation of the overall operation process of the conveying device:

[0055] When it is necessary to perform random inspection of the material sheet, manually operate the inspection button on the operation panel 130. The position sensor 70 of the first conveying structure 20 first checks whether a material sheet is detected. If a material sheet is detected, the first blocking mechanism 50 does not operate. If no material sheet is detected, the third driving member 53 first drives the second driving member 51 to extend in the X direction. The second driving member 51 drives the first blocking member 52 to rise, making the first blocking member 52 higher than the conveying surface of the first conveying structure 20, thus intercepting the material sheet. When the material sheet passes the deceleration sensor 60 of the first conveying structure 20, it begins to decelerate and stops when it reaches the position of the position sensor 70. After the material sheet stops, the third driving member 53 drives the second driving member 51 to retract, causing the material sheet to move slightly in the opposite direction, so that the material sheet moves along the Y direction. The reference edge during conveying can remain consistent. The lifting mechanism 80 drives the first conveying structure 20 to descend as a whole. When the first conveying structure 20 descends to a level lower than the conveying surface of the second conveying structure 30, the material sheet flows onto the second conveying structure 30, driving the second conveying structure 30 and the third conveying structure 40. The material sheet is then conveyed along the Y direction and flows out to the sheet removal position. After the material sheet is in place, manually press the start button on the operation panel 130. The safety light curtain 120 will shield the alarm, and personnel can then perform the inspection operation. After the inspection is completed, click the finish button on the operation panel 130. The material sheet moves into the housing 10 and rises to the initial position. The second drive member 51 of the first blocking mechanism 50 drives the first blocking member 52 to retract. Manually click the light curtain reset button to end the sampling inspection process.
