Description

[0002] A TRAY tray is a tooling for loading semiconductor chips in the semiconductor packaging field. The processed semiconductor chips are often loaded in TRAY trays for storage or transportation. When transporting the TRAY trays filled with semiconductor chips, multiple TRAY trays are often stacked and banded for transportation. However, during transportation, due to structural movement, the stacked TRAY trays will inevitably shift, resulting in missing or damaged products loaded in the TRAY trays.

[0003] With the development of technology, a detection device has emerged. The detection device includes a carrying mechanism and a detection mechanism. The carrying mechanism can drive the stacked TRAY trays to rotate, so that the detection mechanism can detect the appearance of the TRAY trays and check whether the stacked TRAY trays are shifted. However, during the rotation of the stacked TRAY trays driven by the carrying mechanism, the stacked TRAY trays are likely to fall off the carrying mechanism, reducing the stability of the carrying mechanism for carrying the TRAY trays.

[0050] To make the technical problems solved by the present invention, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the present invention will be further described below with reference to the accompanying drawings and through specific embodiments.

[0051] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "above", and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below", and "under" the second feature includes the first feature being directly below and obliquely below the second feature, or simply indicating that the horizontal height of the first feature is lower than that of the second feature.

[0053] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "left", and "right" are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0054] As Figure 1 shown, this embodiment provides an automatic detection device 100 for a TRAY tray, which can detect the appearance of the stacked TRAY trays 200, thereby avoiding problems such as displacement of the stacked TRAY trays 200 during transportation, and ensuring the reliability of the products loaded on the TRAY trays 200.

[0055] Specifically, as Figure 1As shown in the figure, the automatic detection device 100 of the TRAY tray includes a carrying mechanism 1, a detection mechanism 2, and a support plate 5. Among them, the detection mechanism 2 is arranged on the support plate 5, and the detection mechanism 2 is located on the left side of the carrying mechanism 1. The carrying mechanism 1 can pass through the support plate 5 from bottom to top to carry and lift the stacked TRAY trays 200, and the carrying mechanism 1 can drive the stacked TRAY trays 200 to rotate, so as to facilitate the detection mechanism 2 to detect the appearance of the stacked TRAY trays 200. Specifically, the detection mechanism 2 can photograph the appearance of the TRAY tray 200 and send the photographed information to the image analysis software inside the detection mechanism 2, so as to judge whether there are problems such as the deviation of the edges and the overall of the stacked TRAY trays 200.

[0056] Preferably, the distance between the detection mechanism 2 and the carrying mechanism 1 is adjustable, so as to adjust the distance between the detection mechanism 2 and the stacked TRAY trays 200, so as to ensure that the detection mechanism 2 can clearly photograph the appearance of the entire TRAY tray 200.

[0057] Combined with Figure 1 The specific structure of the detection mechanism 2 will be described. As Figure 1 shown in the figure, the detection mechanism 2 includes a camera 21, a support frame 22, and a first driving component 23. Among them, the camera 21 can photograph the appearance of the TRAY tray 200. The first driving component 23 is arranged on the support plate 5, the camera 21 is arranged on the support frame 22, and the first driving component 23 can drive the support frame 22 to move in the left-right direction, so that the camera 21 approaches or moves away from the stacked TRAY trays 200. Specifically, the first driving component 23 includes a motor, a lead screw, and a nut. The motor is arranged on the support plate 5, the lead screw extends in the left-right direction and is connected to the output end of the motor, the nut is connected to the support frame 22, and the lead screw is threadedly connected to the nut. The motor drives the lead screw to rotate to drive the nut and the support frame 22 to move in the left-right direction. Using a lead screw and nut for the transmission connection between the motor and the support frame 22 can greatly improve the stability of the support frame 22 moving in the left-right direction and improve the operation accuracy of the support frame 22.

[0058] Combined with Figure 2 The specific structure of the carrying mechanism 1 will be described. As Figure 2As shown in the figure, the carrying mechanism 1 includes a carrying component 11, a clamping component 12, and a rotating component 13. Among them, the carrying component 11 is used to carry the stacked TRAY trays 200. The clamping component 12 can clamp and fix the stacked TRAY trays 200 on the carrying component 11. The rotating component 13 can drive the carrying component 11, the clamping component 12, and the stacked TRAY trays 200 to rotate, so that the camera 21 can detect the appearance of the stacked TRAY trays 200. By setting the clamping component 12, it is possible to prevent the stacked TRAY trays 200 from falling off the carrying component 11 during the rotation of the carrying component 11 driving the stacked TRAY trays 200, improving the reliability and stability of the carrying component 11 for carrying the stacked TRAY trays 200.

[0059] Combined with Figure 2 The specific structure of the carrying component 11 will be described, as Figure 2 As shown in the figure, the carrying component 11 includes a carrying plate 111, support columns 112, and a bottom plate 113. Among them, both ends of the support columns 112 are fixed to the carrying plate 111 and the bottom plate 113 respectively. The carrying plate 111 is located above the support columns 112, and the bottom plate 113 is located below the support columns 112. The carrying plate 111 is used to carry the stacked TRAY trays 200.

[0060] Preferably, as Figure 2 As shown in the figure, there are four support columns 112. The four support columns 112 are arranged at intervals and are respectively located at the four corners of the carrying plate 111 to ensure stable support for the carrying plate 111. It should be noted that in other embodiments, the number of support columns 112 can also be set to other numbers as long as it can ensure stable support for the carrying plate 111.

[0061] Combined with Figure 2 The specific structure of the rotating component 13 will be described, as Figure 2 As shown in the figure, the rotating component 13 includes a rotating part 131, a rotating fixing frame 132, and a rotating table 133. Among them, the rotating part 131 is arranged on the rotating fixing frame 132. The rotating part 131 can drive the rotating table 133 to rotate relative to the rotating fixing frame 132. The bottom plate 113 is fixed on the rotating table 133. The rotating part 131 can drive the rotating table 133 and the bottom plate 113 to rotate together relative to the rotating fixing frame 132. Specifically, the rotating part 131 can be a rotating motor, and the rotating motor drives the rotating table 133 to rotate through gear transmission.

[0062] Preferably, as Figure 2As shown, the rotating assembly 13 further includes an electric slip ring 134. The electric slip ring 134 is disposed below the rotating fixing frame 132, and all the wire harnesses to be connected on the bearing mechanism 1 are connected to relevant devices through the electric slip ring 134. By providing the electric slip ring 134, it is avoided that the wire harnesses are wound together during the rotation of the bearing assembly 11, ensuring the stability of the wire harness connection. Since the specific structure and principle of the electric slip ring 134 belong to the prior art, they will not be elaborated here.

[0063] In this embodiment, as Figure 2 shown, the clamping assembly 12 includes a first driving member 121, a connecting rod member 122, a first clamping jaw 123, and a second clamping jaw 124. Among them, the middle of the connecting rod member 122 is connected to the output end of the first driving member 121. The first clamping jaw 123 and the second clamping jaw 124 are symmetrically arranged along the left - right direction with respect to the stacked TRAY tray 200 as the axis of symmetry. The two ends of the connecting rod member 122 are respectively pivotally connected to the first clamping jaw 123 and the second clamping jaw 124. The first driving member 121 can drive the connecting rod member 122 to rotate, so that the connecting rod member 122 drives the first clamping jaw 123 and the second clamping jaw 124 to move towards the stacked TRAY tray 200 at the same time, so that the first clamping jaw 123 and the second clamping jaw 124 respectively clamp on both sides of the stacked TRAY tray 200, ensuring the stable fixation of the TRAY tray 200 on the bearing assembly 11. It should be noted that when the first clamping jaw 123 and the second clamping jaw 124 do not need to clamp and fix the TRAY tray 200, the first driving member 121 drives the connecting rod member 122 to rotate in the reverse direction, so that the connecting rod member 122 drives the first clamping jaw 123 and the second clamping jaw 124 to move away from the stacked TRAY tray 200 at the same time. By providing the connecting rod member 122, the first driving member 121 can drive the first clamping jaw 123 and the second clamping jaw 124 to approach or separate from each other at the same time, with a simple structure and convenient operation. Specifically, the first driving member 121 can be a rotating motor, and the rotating motor works reliably and stably.

[0064] In order to increase the stroke of the connecting rod member 122 driving the first clamping jaw 123 and the second clamping jaw 124 to move, as Figure 3As shown, the connecting rod member 122 includes a rotating rod 1221, a first connecting rod 1222, and a second connecting rod 1223. Among them, the middle of the rotating rod 1221 is connected to the output end of the first driving member 121. The two ends of the rotating rod 1221 are respectively pivotally connected to one end of the first connecting rod 1222 and one end of the second connecting rod 1223. The other end of the first connecting rod 1222 is pivotally connected to the first jaw 123, and the other end of the second connecting rod 1223 is pivotally connected to the second jaw 124. When the rotating rod 1221 rotates, it can drive the first connecting rod 1222 and the second connecting rod 1223 to respectively pull the first jaw 123 and the second jaw 124 to approach or move away from each other, greatly increasing the stroke of the first jaw 123 and the second jaw 124 approaching and moving away from each other, so that the clamping assembly 12 can clamp and fix the large-size stacked TRAY trays 200.

[0065] Preferably, as Figure 4 shown, the clamping assembly 12 further includes a first guiding member 125. The first guiding member 125 includes a first guide rail 1251 and a first slider 1252 that are slidably connected. The first guide rail 1251 extends in the left-right direction. First sliders 1252 are fixed on both the first jaw 123 and the second jaw 124. By providing the first guiding member 125, it provides a guiding effect for the relative movement of the first jaw 123 and the second jaw 124 with respect to the bearing assembly 11, preventing the first jaw 123 and the second jaw 124 from shifting during the movement and ensuring the stability of the movement of the first jaw 123 and the second jaw 124.

[0066] In addition, as Figure 4 shown, the bearing mechanism 1 further includes a sliding plate 14 and a lifting assembly 15. Among them, the clamping assembly 12 is arranged on the sliding plate 14. The sliding plate 14 is slidably sleeved on the support column 112. The lifting assembly 15 can drive the sliding plate 14 to rise relative to the support column 112, so that the first jaw 123 and the second jaw 124 extend out of the bearing plate 111, thereby ensuring that the first jaw 123 and the second jaw 124 can respectively clamp on both sides of the stacked TRAY trays 200. It should be noted that when the stacked TRAY trays 200 are conveyed onto the bearing plate 111, the lifting assembly 15 can drive the sliding plate 14 to descend relative to the bearing plate 111, ensuring that the first jaw 123 and the second jaw 124 are flush with the bearing plate 111 or lower than the height of the bearing plate 111, thereby avoiding interference of the first jaw 123 and the second jaw 124 with the bearing of the TRAY trays 200 by the bearing plate 111. It should be noted that the first guide rail 1251 is fixed on the upper end surface of the sliding plate 14, and the first driving member 121 is also arranged on the sliding plate 14.

[0067] Specifically, as Figure 4As shown in the figure, the lifting assembly 15 includes a driving motor 151, a turbine 152 and a worm 153. Among them, the driving motor 151 is arranged on the sliding plate 14, the output end of the driving motor 151 is connected to the turbine 152, the turbine 152 meshes with the worm 153, the worm 153 extends in the up and down direction, and both ends of the worm 153 are respectively rotatably connected to the bearing plate 111 and the bottom plate 113. And the worm 153 passes through the sliding plate 14 and is threadedly connected to the sliding plate 14. When the driving motor 151 rotates, it can drive the turbine 152 and the worm 153 to rotate, so that the sliding plate 14 moves up and down along the worm 153 and the support column 112. By setting the turbine 152 and the worm 153, the transmission connection between the sliding plate 14 and the driving motor 151 is realized, and the transmission is stable and the noise is small.

[0068] In addition, as Figure 1 shown, the TRAY tray automatic detection device 100 further includes a conveying mechanism 3 and a lifting mechanism 4. Among them, the conveying mechanism 3 is used to convey the stacked TRAY trays 200 to a preset position, and the lifting mechanism 4 can drive the bearing mechanism 1 to rise, so that the bearing plate 111 penetrates through the support plate 5 at the preset position to carry and lift the stacked TRAY trays 200 conveyed by the conveying mechanism 3 at the preset position, so as to facilitate the camera 21 to photograph the appearance of the stacked TRAY trays 200.

[0069] Combined with Figure 2 the specific structure of the lifting mechanism 4 will be described. As Figure 2 shown, the lifting mechanism 4 includes a second driving component 41, a support platform frame 42, a lifting platform frame 43 and a telescopic rod 44. Among them, the rotary fixing frame 132 is fixed on the lifting platform frame 43, the upper and lower ends of the telescopic rod 44 are respectively connected to the lifting platform frame 43 and the support platform frame 42, the second driving component 41 is arranged on the support platform frame 42, and the output end of the second driving component 41 is connected to the lifting platform frame 43. When the second driving component 41 drives the lifting platform frame 43 to lift relative to the support platform frame 42, the telescopic rod 44 expands and contracts, so as to ensure that the lifting platform frame 43 drives the entire bearing mechanism 1 to rise or fall. Specifically, the second driving component 41 can be a linear motor or a lifting cylinder, and the specific form of the second driving component 41 is not specifically limited in this embodiment.

[0070] Preferably, as Figure 2 shown, four telescopic rods 44 are provided, and the four telescopic rods 44 are arranged at intervals and are respectively located at the four corners of the lifting platform frame 43 to ensure the telescopic support of the lifting platform frame 43. It should be noted that in other embodiments, the telescopic rod 44 can also be set to other numbers, as long as it can ensure the stable support of the lifting platform frame 43.

[0071] Combined with Figure 5The specific structure of the conveying mechanism 3 will be described. For example, Figure 5 As shown in the figure, the conveying mechanism 3 includes a conveying component 31 and a centering component 32. Among them, the conveying component 31 is used to convey the stacked TRAY trays 200 to a preset position in the front-rear direction, and the centering component 32 is used to center the stacked TRAY trays 200 conveyed by the conveying component 31 at the preset position, so as to ensure that the stacked TRAY trays 200 are neatly placed at the preset position, so that the carrier plate 111 can carry and lift the neatly placed TRAY trays 200, and ensure the accuracy of the detection mechanism 2 for detecting the stacked TRAY trays 200.

[0072] In this embodiment, as Figure 5 shown, the conveying component 31 includes two groups of conveying fixing plates 311 and conveyor belts 312. Among them, the two groups of conveying fixing plates 311 are arranged at intervals in the left-right direction and fixed on the support plate 5. The two groups of conveying fixing plates 311 are respectively arranged on both sides of the stacked TRAY trays 200, and conveyor belts 312 are arranged on both groups of conveying fixing plates 311. The two groups of conveyor belts 312 jointly convey both sides of the stacked TRAY trays 200 in the width direction. By setting the two groups of conveyor belts 312 to jointly convey both sides of the stacked TRAY trays 200 in the width direction, it can ensure that the conveying component 31 conveys more smoothly and stably. Since the specific structure of the conveyor belt 312 belongs to the prior art, it will not be elaborated here.

[0073] Combined with Figure 5 the specific structure of the centering component 32 will be described. For example, Figure 5As shown, the centering assembly 32 includes a second driving member (not shown in the figure), a traction rod 321, and two groups of centering roller members 322. Among them, the two groups of centering roller members 322 are symmetrically arranged in the left-right direction and are respectively arranged outside the two groups of conveying fixing plates 311. The middle of the traction rod 321 is connected to the output end of the second driving member, and the two ends of the traction rod 321 are respectively pivotally connected to the two groups of centering roller members 322. When the second driving member rotates, the second driving member can drive the traction rod 321 to rotate around its middle as the center, so that the traction rod 321 can simultaneously drive the two groups of centering roller members 322 to move towards the direction close to the stacked TRAY trays 200, so that the two groups of centering roller members 322 are respectively abutted against both sides of the stacked TRAY trays 200, thereby realizing the centering and positioning of the stacked TRAY trays 200. It should be noted that after the centering and positioning of the stacked TRAY trays 200 is completed, the second driving member drives the traction rod 321 to rotate in the reverse direction, so that the traction rod 321 can simultaneously drive the two groups of centering roller members 322 to move away from each other. By setting the traction rod 321, the second driving member can simultaneously drive the two groups of centering roller members 322 to approach or move away from each other, with a simple structure and convenient operation. Specifically, the second driving member can be a rotating motor, and the rotating motor works reliably and stably.

[0074] In addition, as Figure 5 shown, the centering assembly 32 further includes a second guiding member 323. The second guiding member 323 includes a second guide rail 3231 and a second slider 3232 that are slidably connected. Among them, the second guide rail 3231 is fixed on the support plate 5, and the second guide rail 3231 extends along the direction in which the centering roller member 322 approaches the stacked TRAY tray 200, that is, extends in the left-right direction in the figure, and the second sliders 3232 are fixed on both groups of centering roller members 322. By setting the second guiding member 323, it provides a guiding effect for the movement of the two groups of centering roller members 322 to approach and move away from each other relative to the conveying assembly 31, prevents the two groups of centering roller members 322 from shifting during the movement, and ensures the stability of the movement of the two groups of centering roller members 322.

[0075] Combined with Figure 5 the specific structure of the centering roller member 322 will be described. As Figure 5As shown in the figure, the centering roller member 322 includes a centering fixing plate 3221 and a centering roller 3222. Among them, a second slider 3232 is fixed on the centering fixing plate 3221, and the centering roller 3222 is fixed on the centering fixing plate 3221. When the centering fixing plate 3221 moves along the second guide rail 3231 towards the stacked TRAY trays 200, the centering roller 3222 abuts against one side of the stacked TRAY trays 200. By providing the centering roller 3222 to achieve centering by abutting against the stacked TRAY trays 200, the protection of the TRAY trays 200 can be improved. Preferably, in this embodiment, two centering rollers 3222 are provided on the centering fixing plate 3221, and the two centering rollers 3222 are arranged at intervals in the front-rear direction and can jointly abut against the side of the TRAY tray 200 to further ensure the accuracy of centering.

[0076] To increase the stroke of the traction rod 321 driving the two centering roller members 322, as Figure 5 shown, the traction rod 321 includes a rotating rod 3211, a first traction rod 3212, and a second traction rod 3213. Among them, the middle of the rotating rod 3211 is connected to the output end of the second driving member, and the two ends of the rotating rod 3211 are respectively pivotally connected to one end of the first traction rod 3212 and one end of the second traction rod 3213. The other ends of the first traction rod 3212 and the second traction rod 3213 are respectively pivotally connected to the centering fixing plates 3221 of the two centering roller members 322. When the rotating rod 3211 rotates, it can drive the first traction rod 3212 and the second traction rod 3213 to respectively pull the two centering fixing plates 3221 closer to or away from each other, greatly increasing the stroke of the two centering fixing plates 3221 approaching and moving away from each other, so that the centering roller 3222 can perform centering and positioning on the large-sized stacked TRAY trays 200.

[0077] To facilitate understanding of the TRAY tray automatic detection device 100 disclosed in this embodiment, in combination with Figures 1 to 5 the specific working process of the TRAY tray automatic detection device 100 will be described as follows:

[0078] First of all, the two conveyor belts 312 jointly convey both sides in the width direction of the TRAY tray 200 in the front-rear direction until the TRAY tray 200 is conveyed to a preset position.

[0079] Secondly, the two centering roller members 322 jointly move towards the TRAY tray 200 until the two centering roller members 322 respectively abut against both sides in the width direction of the TRAY tray 200 to achieve centering and positioning of the TRAY tray 200.

[0080] At this time, the first jaw 123 and the second jaw 124 on the carrying mechanism 1 below the conveyor belt 312 are arranged at intervals in the left-right direction and are respectively located on both sides of the TRAY tray 200 in the width direction. Then, the rotating assembly 13 drives the carrying assembly 11 and the clamping assembly 12 to rotate below the conveyor belt 312 until the first jaw 123 and the second jaw 124 are arranged at intervals in the front-back direction, and the first jaw 123 and the second jaw 124 are respectively located on both sides of the TRAY tray 200 in the length direction;

[0081] Then, the first driving member 121 drives the first jaw 123 and the second jaw 124 to move away from each other until the TRAY tray 200 is located between the first jaw 123 and the second jaw 124;

[0082] Then, the lifting mechanism 4 drives the entire carrying mechanism 1 to rise so that the carrying plate 111 on the carrying mechanism 1 carries and lifts the TRAY tray 200 on the conveyor belt 312;

[0083] Then, the lifting assembly 15 drives the sliding plate 14 to rise until the first jaw 123 and the second jaw 124 extend out of the carrying plate 111. At this time, the first driving member 121 drives the first jaw 123 and the second jaw 124 to approach each other until the first jaw 123 and the second jaw 124 are respectively clamped on both sides of the TRAY tray 200 in the length direction, and the TRAY tray 200 is firmly fixed on the carrying plate 111;

[0084] Finally, the rotating assembly 13 drives the carrying assembly 11, the TRAY tray 200, and the clamping assembly 12 to rotate together to facilitate the inspection mechanism 2 to inspect the appearance of the TRAY tray 200.
