[0044] This application proposes an automatic tray-setting device, referring to... Figures 1 to 4 The automatic tray-loading device includes: a first conveying mechanism 11 for conveying trays; a first positioning mechanism 21 disposed on the first conveying mechanism 11 for positioning the trays; a second conveying mechanism 12 disposed on one side of the first conveying mechanism 11 for conveying fixtures; a second positioning mechanism 22 disposed on the second conveying mechanism 12 for positioning the fixtures; a first robotic arm 13 disposed between the first conveying mechanism 11 and the second conveying mechanism 12; and a transfer platform 14 disposed on one side of the first robotic arm 13 for positioning workpieces. The first robotic arm 13 is used to transfer workpieces from the trays to the transfer platform 14, and the first robotic arm 13 is also used to transfer workpieces from the transfer platform 14 to the fixtures.

[0045] The automatic tray-loading device in this embodiment can automatically transfer trays via the first conveying mechanism 11 and automatically transfer fixtures via the second conveying mechanism 12. Workpieces stacked in the trays are picked up by the first robotic arm 13, positioned on the transfer platform 14, and then sequentially placed into the fixtures in batches. The tray-loading process allows for precise positioning of workpieces in the fixtures before processing; subsequent processing only requires positioning the fixtures before processing the workpieces within them, thus improving processing efficiency.

[0046] In this embodiment, the first conveying mechanism 11 includes two conveyor belts arranged side by side. The second conveying mechanism 12 can also use two conveyor belts arranged side by side. The first conveying mechanism 11 and the second conveying mechanism 12 can be arranged in parallel, and the conveying direction is along the first direction. The first positioning mechanism 21 can be a pair of cylinders mounted on the first conveying mechanism 11. The push rod end of the cylinder is provided with a first clamping member 211. When the cylinder push rods push out in opposite directions, the first clamping member 211 can clamp the material tray. The second positioning mechanism 22 can also adopt the same structure, that is, a pair of cylinders are mounted on the second conveying mechanism 12, and the push rod end of the cylinder is provided with a second clamping member 221. The second clamping member 221 can clamp both sides of the fixture. The clamping direction of the first positioning mechanism 21 and the second positioning mechanism 22 is along the second direction. The first direction and the second direction can be perpendicular to each other and both are horizontal directions.

[0047] The first positioning mechanism 21 also needs to limit the material tray in the first direction. Specifically, the first positioning mechanism 21 can be set on the first conveying mechanism 11, and a first stop can be set between the two conveyor belts of the first conveying mechanism 11 to prevent the material tray from continuing to be conveyed. When the first stop blocks the material tray, the first clamping member 211 can clamp the two sides of the material tray to complete the positioning of the material tray. Of course, when it is necessary to release the material tray to continue moving, the above-mentioned first stop and first positioning mechanism 21 can be set in the middle section of the first conveying mechanism 11. The first stop can be a first limiting member 212, which is set between the conveyor belts. In addition, the first positioning mechanism 21 also includes a first lifting cylinder for driving the first limiting member 212 to rise. The first limiting member 212 can prevent the material tray from moving along the first direction. When the first limiting member 212 falls below the conveyor belt, the material tray can be released so that it can be transferred to the next station.

[0048] The transfer platform 14 may include a mounting platform 141 and a positioning cylinder 142 and a positioning block 143 mounted on the mounting platform 141. The side of the positioning block 143 may be provided with a V-groove, which limits the workpiece. The actuator of the positioning cylinder 142 and the positioning block 143 can be used to clamp the workpiece for positioning. The workpiece can be a circular glass sheet. Of course, for workpieces of different shapes, the V-groove of the positioning block 143 can be adaptively adjusted to match the outer contour of the workpiece. Furthermore, the actuator of the first robotic arm 13 may be provided with a suction cup for adsorbing the workpiece. A negative pressure can be created in the suction cup to pick up the workpiece, and the negative pressure can be released to release the workpiece.

[0049] In some embodiments, the automatic tray-stacking device further includes a lifting mechanism 23 located below the first positioning mechanism 21. The lifting mechanism 23 includes a plurality of lifting components 231 and a lifting drive component 232 for driving the lifting components 231 to rise and fall. The lifting components 231 are used to lift the workpieces in the tray. In this embodiment, each material cavity of the tray has a through hole at its bottom, through which the lifting component 231 can lift the workpiece. The lifting mechanism 23 includes a lifting mounting plate 233, and the lifting component 231 includes a plurality of lifting rods disposed on the lifting mounting plate 233. The arrangement of the lifting rods can correspond to the arrangement of the material cavities, with each lifting rod corresponding to a material cavity during lifting. In specific arrangements, both can be arranged in an array. The lifting component 231 is located between the two conveyor belts of the first conveying mechanism 11, and the lifting drive component 232 can be an electric cylinder or a lifting platform. After the first clamping component 211 clamps and positions the tray, the first robotic arm 13 can pick up the material. Of course, the vertical downward reach of the suction cups at the actuator end of some robotic arms is fixed. Workpieces are stacked in the various chambers of the material tray, for example, five workpieces in each chamber. After the top workpiece in all chambers is removed, the top-loading drive 232 drives the top rod to rise a certain height, the same as the workpiece thickness, to prepare for the next round of picking. The picking height can be controlled so that the distance between the lower surface of the picked-up workpiece and the upper surface of the material tray is less than the thickness of one workpiece. When the picked-up workpiece adheres to the workpiece below, it can be moved horizontally, using the sidewall of the material chamber to laterally push and separate the workpiece below.

[0050] In some embodiments, the automatic tray-distributing device further includes a tray-separating mechanism 30, which includes: two first material racks 31, disposed on both sides of the first conveying mechanism 11 and spaced apart from each other, forming a first supply compartment for accommodating the material tray; and a material rack driving assembly 32, used to drive the two first material racks 31 to move towards or away from each other, the movement direction of the first material racks 31 intersecting the conveying direction of the first conveying mechanism 11. In this embodiment, the two first material racks 31 are slidably disposed on the machine base 10, and the sliding direction can be along a second direction. The material rack driving assembly 32 can be a cylinder or an electric cylinder driven and connected to the first material racks 31 to drive the two first material racks 31 to open and close. The first material rack 31 includes a frame body and two angle steels vertically disposed above the frame body. The angle steels are used to limit the four corners of the material tray, and the space formed by the four angle steels constitutes the first supply compartment. The lower end of the frame body is slidably connected to the machine base 10 through a slide rail and a slider, and the material rack driving assembly 32 is driven and connected to the frame body. The first material rack 31 has an openable design, which can be used to accommodate material trays of different sizes, and also facilitates material feeding, that is, it is easy to put the material tray into the first supply compartment from the side.

[0051] In addition, the tray-separating mechanism 30 further includes: a first lifting assembly 33, disposed between two first material racks 31, for lifting the material trays; and a layering assembly, including a layering insert plate 34 disposed on the first material rack 31, and a layering drive member for driving the layering insert plate 34 to insert into the stacked material trays. In this embodiment, the first lifting assembly 33 may be an electric cylinder located between the two conveyor belts of the first conveying mechanism 11, with its drive end facing upward and its driving direction along the vertical direction. The drive end of the first lifting assembly 33 is provided with a first support frame, which is used to support the material trays.

[0052] The layering plate 34 is located at the upper end of the frame and is slidably connected to the frame, sliding in the second direction. The layering drive can be a cylinder, which drives the two layering plates to move towards each other, inserting between the bottom tray and the upper tray in the first supply bin to receive the upper tray. The bottom tray descends with the first lifting assembly 33 onto the first conveying mechanism 11 and is then conveyed to the next station by the first conveying mechanism 11. Subsequently, the first lifting assembly 33 rises to receive the upper tray. The layering plate 34 retracts, and the first lifting assembly 33 moves downwards by the thickness of one tray, allowing the layering plate 34 to perform the next layering operation and release the current bottom tray in the first supply bin again. The cooperation between the tray-separating mechanism 30 and the first conveying mechanism 11 enables automatic tray separation and automatic material transfer and feeding.

[0053] In some embodiments, the automatic tray-stacking device further includes a tray-stacking mechanism 40 disposed on the first conveying mechanism 11. The tray-splitting mechanism 30, the first positioning mechanism 21, and the tray-stacking mechanism 40 are arranged sequentially along the conveying direction of the first conveying mechanism 11. The tray-stacking mechanism 40 is used to collect and stack trays. In this embodiment, by providing the tray-stacking mechanism 40, empty trays can be collected and stacked.

[0054] Specifically, the stacking mechanism 40 includes: a first recycling bin 42 located above the first conveying mechanism 11; a second lifting assembly 43 located below the first recycling bin 42 for driving the entire tray in the first recycling bin 42 to rise; and a support member 45 rotatably located below the first recycling bin 42 for receiving the tray, wherein the support member 45 can be flipped upward to avoid the tray being lifted by the second lifting assembly 43.

[0055] In this embodiment, the stacking mechanism 40 includes second material racks 41 disposed on both sides of the first conveying mechanism 11. The first recycling bin 42 can also be made of four angle steels, with two steels disposed on one of the second material racks 41 and the other two on the other second material rack 41. The four angle steels are located above the first conveying mechanism 11 to position the four corners of the material trays. The material trays are stacked in the first recycling bin 42. The second lifting assembly 43 can be an electric cylinder or pneumatic cylinder disposed between the two conveyor belts of the first conveying mechanism 11, with its drive end facing upward and a second support frame provided on the drive end for supporting the material trays. A support member 45 can be hinged to the upper end of the second material rack 41. The support member 45 is located between the two angle steels, with one end of the support member 45 hinged to the second material rack 41, and the hinge axis can be parallel to the first direction. The other end extends toward the opposite second material rack 41 and can be used to support the material trays. The hinged support 45 allows the tray to pass unidirectionally from bottom to top under the drive of the second lifting assembly 43. That is, when the tray rises, the support 45 flips upwards to prevent the tray below from rising. When the tray rises above the support 45, the support 45 automatically swings down under gravity and remains flat. The second lifting assembly 43 then lowers the tray, which is supported by the support 45. The second lifting assembly 43 continues to lower the tray below the second conveyor mechanism 12 until the next tray enters the area directly below the first recycling bin 42. It is worth noting that, to limit the tray's movement in the first direction, a second stop 44 can be provided on the side of the first recycling bin 42 away from the first supply bin to block the tray, ensuring that the tray's position corresponds to the first recycling bin 42. From a vertical projection perspective, the tray is precisely within the first recycling bin 42.

[0056] In some embodiments, the automatic tray-loading device further includes: a second supply compartment 51, disposed near the first end of the second conveying mechanism 12, for supplying a fixture; and a second robotic arm 60, for transferring the fixture from the second supply compartment 51 to the second conveying mechanism 12. The second supply compartment 51 may be disposed on the side of the second conveying mechanism 12 away from the first robotic arm 13, and the conveying direction of the first conveying mechanism 11 is opposite to the conveying direction of the second conveying mechanism 12. The second robotic arm 60 includes a first translation cylinder 61 disposed across the top of the second conveying mechanism 12, a first mounting base 62 disposed at the moving end of the first translation cylinder 61, a second lifting cylinder 63 disposed on the first mounting base 62, a first mounting plate 66 disposed at the lower end of the push rod of the second lifting cylinder 63, first clamping cylinders 64 disposed at both ends of the first mounting base 62, a third clamping member 65 disposed on the push rod of the first clamping cylinder 64, and a suction cup disposed on the first mounting plate 66 and located between the two first clamping cylinders 64.

[0057] The first translation cylinder 61 can be driven in a second direction, and the first clamping cylinder 64 can be clamped in a first direction. The second lifting cylinder 63 can drive the suction cup to descend and pick up the fixture, then raise the fixture between the two third clamping members 65, where the first clamping cylinder 64 drives the third clamping members 65 to clamp the fixture. The second robotic arm 60 can be used to clamp and pick up the fixture in the second supply chamber 51 and place it on the conveyor belt of the second conveying mechanism 12. Furthermore, a third lifting assembly 52 can be provided at the lower part of the second supply chamber 51. The third lifting assembly 52 can be an electric cylinder with its drive end facing upwards, used to lift the stacked fixtures in the second supply chamber 51 so that the fixtures can dock with the second robotic arm 60 above. By providing the second supply chamber 51 and the second robotic arm 60, fixtures can be continuously supplied to the second conveying mechanism 12.

[0058] Furthermore, the second positioning mechanism 22 can be located in the middle section of the second conveying mechanism 12. Specifically, a pair of cylinders can be installed on the second conveying mechanism 12, with a second clamping member 221 installed at the end of the cylinder push rod, and two third limiting members 222 installed. One third limiting member 222 is spaced apart from one of the second clamping members 221 and is used to clamp a pair of sides of the fixture. The other third limiting member 222 is spaced apart from the other second clamping member 221 and is used to clamp the other pair of sides of the fixture, thereby clamping and fixing the fixture. The clamping directions of the second positioning mechanism 22 are along the first direction and the second direction, both of which are horizontal. Of course, a fourth lifting assembly 54 can also be installed below the second positioning mechanism 22, which is used to lift the fixture, causing it to disengage from the second conveying mechanism 12, and to limit the fixture in the vertical direction.

[0059] In some embodiments, the automatic tray-loading device further includes: a second recovery bin 53, disposed near the tail end of the second conveying mechanism 12, for recovering the fixture; and a third robotic arm 70, for transferring the fixture from the second conveying mechanism 12 to the second recovery bin 53. The third robotic arm 70 includes a second translation cylinder 71 disposed parallel to the second conveying mechanism 12, a second mounting base 72 disposed at the moving end of the second translation cylinder 71, a third lifting cylinder 73 disposed on the second mounting base 72, a second mounting plate 76 disposed at the lower end of the push rod of the third lifting cylinder 73, second clamping cylinders 74 disposed at both ends of the second mounting base 72, a fourth clamping member 75 disposed on the push rod of the second clamping cylinder 74, and a suction cup disposed on the second mounting plate 76 and located between the two second clamping cylinders 74. The driving direction of the second translation cylinder 71 may be along a first direction, and the clamping direction of the second clamping cylinder 74 may be along a second direction.

[0060] The suction cup can be driven by the third lifting cylinder 73 to descend and pick up the fixture, and then the fixture can be driven to rise between the two fourth clamping members 75. The fourth clamping members 75 are then driven by the second clamping cylinder 74 to clamp the fixture. The third robot arm 70 can be used to clamp and pick up the fixture at the second positioning mechanism 22 and place it in the second recovery bin 53.

[0061] Furthermore, a fourth lifting assembly 54 can be installed at the lower part of the second recovery bin 53. The fourth lifting assembly 54 can be an electric cylinder with its drive end facing upwards, used to move the stacked fixtures in the second recovery bin 53 downwards, so that the fixtures on the third robotic arm 70 can be stacked stably, avoiding collisions with the fixtures in the second recovery bin 53. By setting up the second recovery bin 53 and the third robotic arm 70, fixtures can be continuously stacked into the second recovery bin 53.

[0062] Furthermore, the automatic tray-loading device also includes a machine base 10, with a first supply bin and a second recovery bin 53 positioned near the edge of the machine base 10. The machine base 10 has a loading station corresponding to the first supply bin and a unloading station corresponding to the second recovery bin 53. The aforementioned first conveying mechanism 11, first positioning mechanism 21, second conveying mechanism 12, second positioning mechanism 22, first robotic arm 13, and transfer platform 14 are all located on the machine base 10. The first supply bin and the second recovery bin 53 can be located near the same side of the machine base 10 to supply trays to the first supply bin and remove fixtures from the second recovery bin 53. The automatic tray-loading device also includes a trolley for loading and unloading. Unloading the tray allows it to enter the first supply bin from the loading station, and the trolley can also be used to receive fixtures from the second recovery bin 53. A pair of forks can be arranged side-by-side on the side of the trolley for receiving fixtures or trays. The space between the forks also allows for the movement of corresponding lifting components. In addition, rotary cylinders can be installed at the loading and unloading stations respectively. A locking hook can be installed at the rotating end of the rotary cylinder. The rotation of the rotary cylinder can drive the locking hook to rotate and lock the trolley.

[0063] In some embodiments, the second recycling bin 53 includes a receiving plate located at the drive end of the fourth lifting assembly 54, and limiting rods located around the receiving plate. A fixture can be accommodated between the limiting rods and is limited therebetween. The fixture and the receiving plate can move up and down between the limiting rods. It is worth noting that the unloading station is located on the side of the machine base 10, thus forming a notch on the side of the machine base for installing the second recycling bin 53. Correspondingly, one of the limiting rods may be located in the middle area of ​​the notch, potentially obstructing the fixture when the trolley needs to remove it. Therefore, the lower end of the limiting rod can be hinged to the machine base 10, and the limiting rod remains vertical in the working state. When the fixture needs to be removed, the limiting rod can be rotated a certain angle and kept horizontal to prevent the fixture from entering or exiting the second recycling bin 53.

[0064] This application discloses a laser processing equipment, including an automatic tray-stacking device and a frame for mounting the automatic tray-stacking device. The frame can be a support frame or a mounting frame for supporting the aforementioned machine base 10. The laser processing equipment can perform laser processing on workpieces in a fixture, and the specific processing method can be laser engraving, etc. In the embodiments of this application, the working principle of the automatic tray-stacking device laser processing equipment is as follows:

[0065] The automatic tray-loading device and laser processing equipment in this embodiment include a first conveying mechanism 11, a first positioning mechanism 21, a second conveying mechanism 12, a second positioning mechanism 22, a first robotic arm 13, and a transfer platform 14.
