There are four first lifting rods 124. Two first transmission rods 123a, three commutators 121b and four second transmission rods 123b together form an "I" shape. The first motor 121a is mounted on a mounting plate (not shown in the figure), the first motor 121a is located below the mounting plate, and multiple first screw lifts are also mounted on the mounting plate (not shown in the figure). By way of example, four first screw lifts are mounted on the mounting plate, and the first lifting rods 124 are mounted on a mounting frame 125. There are multiple mounting brackets 125, each of which has a first lifting rod 124 screwed to the first spiral lifter 122. Four first lifting rods 124 are mounted on each mounting bracket 125, and each mounting bracket 125 is connected to the lifting platform 110. For example, in the figure, four mounting brackets 125 are mounted on the lifting platform 110. A mounting plate (not shown) is connected to the mobile bracket, which can move on the guide rails on the frame, thereby realizing the movement of the transport device.

When the first motor 121a is operating, the four first spiral lifts will rotate synchronously, synchronously driving the four first lifting rods to move up and down, and the lifting platform 110 will move up and down as a whole.

[0044] The guide portion 126 includes a first sleeve 126a and a first guide rod 126b. Multiple first sleeves 126a are provided, and multiple first guide rods 126b are provided. Multiple first sleeves 126a are mounted on a mounting plate, and the first guide rods 126b pass through the first sleeve 126a. The guide portion 126 and the first lifting rod 124 are both mounted on the same mounting bracket 125, which is fixedly connected to the lifting platform 110. There are multiple guide portions 126, for example, four in the figure: guide portion 1, guide portion 2, guide portion 3, and guide portion 4. The four guide portions 126 are mounted on four corresponding mounting brackets 125. When the transport device is lifted or lowered by the first spiral lifter 122 and the first lifting rod 124, the first guide rod 125b moves within the first sleeve 125a, providing guidance during the lifting movement.

[0045] The second lifting unit 130 includes: a second driving part 131a, a second commutator 131b, a second spiral lifter 132, a transmission member 133, and a second lifting rod 134. The second driving part 131a adopts a motor, which can also be called a second motor 131a. The power of the second motor 131a is transmitted to the second spiral lifter 132 through the transmission member 133 and the second commutator 131b. The second spiral lifter 132 drives the second lifting rod 134 and the second adsorption unit 220 to move up and down. The structure of the second lifting unit 130 is similar to that of the first lifting unit 120. Its specific configuration can be referred to. Figure 1 and Figure 3 The second lifting unit 130 is generally located outside the first lifting unit 120 .

[0046] Specifically, there are multiple second commutators 131b, multiple second spiral elevators 132, transmission members 133 include a first transmission member 133a, a second transmission member 133b, a third transmission member 133c, and a fourth transmission member 133d.

More specifically, there is one second motor 131a, and three second commutators 131b, namely, a first second commutator, a second second commutator, and a third second commutator. For example or alternatively, the first second commutator, the second second commutator, and the third second commutator may be the same or different. There are four second screw elevators 132, namely, second screw elevator 1, second screw elevator 2, second screw elevator 3, and second screw elevator 4. There is one first transmission member 133a, one second transmission member 133b, and two third transmission members 133c, namely, third transmission member 1 and third transmission member 2. For example, or alternatively, third transmission member 1 and third transmission member 2 may be the same or different.

For example, or alternatively, fourth transmission member 1 and fourth transmission member 2 may be the same or different. There are four second lifting rods 134.

When the second motor 131a is operating, the four second screw lifters will rotate synchronously, driving the four second lifters to move up and down, and the second suction unit 220 will move up and down as a whole.

[0049] The first adsorption unit 210 includes: an upper plate 211 and a lower plate 212. The upper plate 211 and the lower plate 212 form a cavity, and multiple cavities can be provided. The lower plate 212 is provided with a through hole, and multiple through holes are provided. Multiple first suction nozzles 212a are provided, and the first suction nozzle 212a is installed on the through hole. Multiple air inlet nozzles 211a are provided on the upper plate 211. The first suction nozzle 212a and the air inlet nozzle 211a are both connected to the cavity. The air inlet nozzle 211a can be connected to a vacuum generator. The first suction nozzle 212a is used to adsorb the workpiece. The first adsorption unit 210 is connected to the lifting platform 110 through a positioning mechanism 211b. The positioning mechanism can be a zero-point positioning mechanism, that is, the first adsorption unit 210 can be removed from the lifting platform 110 without affecting the first lifting unit and the second lifting unit, which is convenient for replacing, adjusting or maintaining the first adsorption unit 210.

[0050] Figure 4 As shown, multiple first suction nozzles 212a are arranged according to a certain pattern. Specifically, five first suction nozzles 212a are located at the four corners and the center of the workpiece to form an array. The lower plate 212 is provided with multiple arrays, for example, 18 columns x 5 rows. The number of columns and rows can be reasonably set according to the size and structure of the actual workpiece. The workpiece can be a screen. It is worth noting that in addition to using multiple suction nozzles, the first suction unit 210 can also use a ceramic suction plate or a porous graphite plate to absorb the workpiece.

[0051] The second suction unit 220 includes: a first suction rod 221, a second suction rod 222, a first air nozzle, a first vacuum suction cup, a second air nozzle, and a second vacuum suction cup. The first suction rod 221 and the second suction rod 222 are both rectangular in structure and are connected to the second lifting rod 134 of the second lifting unit 130. The first suction rod 221 is provided with a plurality of first air nozzles and first vacuum suction cups on the outside, and the first air nozzles are connected to the first vacuum suction cups. The second suction rod 222 is provided with a plurality of second air nozzles and second vacuum suction cups on the outside, and the second air nozzles and second vacuum suction cups are connected. There are multiple first suction rods 221 and multiple second suction rods 222. The multiple first suction rods 221 and the second suction rods 222 form a frame structure. For example, two first suction rods 221 and two second suction rods 222 together form a rectangular frame structure. The multiple first vacuum suction cups and the second vacuum suction cups together form a rectangular distribution. The first suction rod 221 and the second suction rod 222 each form a cavity, which is connected to the first air nozzle and the second air nozzle. It is worth noting that the first adsorption rod and the second adsorption rod do not have the adsorption function in themselves. They are used in the second adsorption unit and are called the first adsorption rod and the second adsorption rod in name. These need to be explained clearly.

[0052] The first suction unit 210 is provided with a first strip hole 210a and a second strip hole 210b. The first strip hole 210a and the second strip hole 210b are arranged corresponding to the first vacuum suction cup and the second vacuum suction cup. Multiple first vacuum suction cups can pass through the first strip hole 210a, and multiple second vacuum suction cups can pass through the second strip hole 210b. The first strip hole 210a and the second strip hole 210b leave sufficient space for the first vacuum suction cup and the second vacuum suction cup to avoid the situation where the first vacuum suction cup and the second vacuum suction cup cannot pass through the strip holes. Therefore, the hole size of the first strip hole 210a and the second strip hole 210b is larger than the structural size of the first vacuum suction cup and the second vacuum suction cup.

[0053] To clean the platform, the handling device of the present invention further includes a cleaning mechanism 300 connected to the lifting platform 110. The cleaning mechanism 300 includes a cleaning unit and a lifting mechanism 330. The cleaning unit is connected to the lifting mechanism 330, which drives the cleaning unit up and down. The cleaning unit is used to contact the loading platform on which the processed workpiece is placed to clean the loading platform.

[0054] Specifically, the cleaning unit includes a first cleaning roller 310, a second cleaning roller 320, and a mounting member 340. The first cleaning roller 310 and the second cleaning roller 320 are arranged alternately in the front-to-back direction. The first cleaning roller 310 and the second cleaning roller 320 are installed on the mounting member 340 and are arranged alternately in the front-to-back direction on the mounting member 340. The lifting mechanism 330 drives the first cleaning roller 310 and the second cleaning roller 320 to move up and down. The lifting mechanism 330 can use lifting components such as cylinders or telescopic rods. After the workpiece is laser processed, the conveying device will transport the processed workpiece to the loading platform for the processed workpiece. The processed workpiece itself may have particles, dust, etc. after laser processing, which will cause the loading platform to be contaminated if left on the platform. Therefore, the loading platform needs to be cleaned, and the corresponding lifting mechanism 330 controls the first cleaning roller 310 and the second cleaning roller 320 to descend. The cleaning rollers contact the loading platform, and the conveying device moves or the loading platform moves to clean the loading platform, thereby avoiding the subsequent contamination of the loading platform by the conveying device to the multiple new screens after processing, thereby improving the product yield.

[0055] To facilitate transport of the processing platform, the transport device of the present invention further includes a transport unit comprising a positioning portion 400 and a clamping portion 500. The positioning portion 400 is used to position the processing platform, and the clamping portion 500 is used to clamp the processing platform. The transport unit is used to transport the processing platform, and a workpiece can be placed on the processing platform for laser processing. Specifically, the positioning portion 400 pre-positions the processing platform, and the clamping portion 500 then clamps the processing platform, allowing the transport unit to transport the processing platform.

[0056] Specifically, there are multiple positioning parts 400, for example, there are two positioning parts 400, and the two positioning parts 400 are installed on both sides of the lifting platform 110. The positioning part 400 includes a positioning member 410, a lifting member 420, and an adjusting member 430. The adjusting member 430 is connected to the lifting member 420, and the lifting member 420 is connected to the positioning member 410. The adjusting member 430 is used to control the lifting member 420 and the positioning member 410 to move away from or closer to the lifting platform 110 or the first adsorption unit 210. The lifting member 420 is used to control the upward and downward movement of the positioning member 410. There can be multiple clamping parts 500, and the clamping parts 500 are installed on both sides of the lifting platform 110. For example, there are four clamping parts 500, and two clamping parts 500 are installed on each side of the lifting platform 110. The clamping parts 500 include a driving member 510 and a clamping member 520. The driving member 510 drives the clamping member 520 to move away from or closer to the lifting platform 110 or the first adsorption unit 210. Therefore, the driving action of the two oppositely arranged driving members 520 can change the distance between the two oppositely arranged clamping members 520 to adapt to the clamping of processing platforms of different sizes. The driving members and lifting members can use conventional cylinders.

[0057] When the transport unit is working, first, the lifting member 420 controls the positioning member 410 to descend, and the inner side of the positioning member 410 contacts one side of the processing platform, and then the lifting member 420 on the other side controls the positioning member 410 to descend, so that the processing platform is positioned between the two positioning parts 400. For example, the processing platform is positioned between the two positioning members 410; then, the driving member 510 of the multiple clamping parts 500 controls the clamping members 520 on both sides of the lifting platform 110 to approach the lifting platform 110 or the first adsorption unit 210, so that the clamping members 520 on both sides are clamped on the processing platform, and finally the transport device is lifted and lowered and / or moved horizontally to transport the processing platform.

[0058] The first suction unit 210 is provided with a plurality of recessed portions. When the clamping member 520 approaches the lifting platform 110 or the first suction unit 210, the clamping member 520 can move into the recessed portion. The provision of the recessed portions can reduce the size of the entire handling device, preventing the use of the clamping member 520 from causing the handling device to be oversized.

[0059] To prevent the processing platform from colliding with the first suction unit 210, which could damage the first suction unit 210, the transport device of the present invention further includes a detection unit 600. Specifically, the detection unit 600 includes multiple sensors for detecting the distance between the first suction unit and the processing platform. While maintaining the transport device at all times horizontal, the detection unit 600 can be appropriately configured based on actual needs.

[0060] The present invention also provides a transport method, which uses any of the above-mentioned transport devices and includes the following steps:

[0061] Step S100: placing the panel on the processing platform C;

[0062] Step S200: The processing platform C moves to the laser processing device, and the laser processing device L processes the panel to form a plurality of processed screen bodies;

[0063] Step S300: transporting the processed screens to the loading platform P;

[0064] Specifically, step S300 includes the following steps:

[0065] Step S301: The transport device moves to the laser processing device. Specifically, the transport device moves along the rack to the front laser processing device. The laser processing device means that the transport device is allowed to be close to the laser processing device L or located to the side of the laser processing device L. This is clear.

[0066] Step S302: The suction mechanism of the transport device sucks the processed panel, and the transport device moves toward the loading platform P. Specifically, the suction mechanism of the transport device sucks the processed panel, and the transport device moves along the rack to approach the loading platform P.

[0067] Step S303: When the transport device moves to above the recovery device, the second suction unit 220 puts the processed panel waste into the recovery device.

[0068] Step S304: When the transport device moves to the top of the loading platform P, the processed screens are placed on the loading platform P. Specifically, when the transport device moves along the rack to the top of the loading platform, the first adsorption unit places the processed screens on the loading platform.

[0069] After step S300, the method further includes step S400: cleaning the loading platform P;

[0070] Specifically, step S400 includes the following steps:

[0071] Step S401 : The cleaning unit of the transport device contacts the loading platform P. Specifically, the transport device moves above the loading platform P, and the first cleaning roller 310 and the second cleaning roller 320 of the cleaning unit are raised or lowered to contact the loading platform.

[0072] Step S402: The transport device moves along the frame or the loading platform, and the first cleaning roller 310 and the second cleaning roller 320 clean the loading platform. Specifically, the first cleaning roller 310 and the second cleaning roller 320 remove dust, particulate matter, cutting chips, etc. from the loading platform P. This achieves adhesive cleaning of the sorting platform by the first cleaning roller 310 and the second cleaning roller 320, which helps keep the loading platform P in a clean working condition.

[0073] Before step S100, the process further includes step SF: transporting the processing platform C to the laser processing device;

[0074] Specifically, step SF includes the following steps:

[0075] Step SF01: The transport unit positions and clamps the processing platform C. Specifically, the positioning unit of the transport unit positions the processing platform C in advance, and the clamping unit clamps the processing platform.

[0076] Step SF02: Place the processing platform C on the laser processing device. Specifically, the transport device moves along the frame, and the transport unit places the processing platform on the laser processing device.
