[0031] Please see Figure 1 and Figure 2 A loading and unloading platform device includes a mounting frame 1, a first platform 2, a first linear drive mechanism 3, a second platform 4, and a second linear drive mechanism 5.

[0032] Mounting bracket 1 has a first position and a second position, which are opposite each other in the horizontal direction, that is, it can move between the first position and the second position by horizontal movement.

[0033] The first material table 2 is slidingly connected to the mounting frame 1 and moves between the first position and the second position. More specifically, two first guide rails 1a are designed between the first material table 2 and the mounting frame 1 for sliding.

[0034] The second material table 4 is slidingly connected to the mounting frame 1 and moves between the first position and the second position. More specifically, two second guide rails 1b are designed between the second material table 4 and the mounting frame 1 for sliding.

[0035] Please refer to Figure 1 , Figure 3 and Figure 4 , and accordingly, the first material table 2 and the second material table 4 need to avoid interference during movement. More specifically, for the first material table 2, the table top is relatively high, and the frame body connected below the table top is a frame 2b. For the second material table 4, the table top is relatively low, and the second material table 4 can pass through the frame body of the first material table 2.

[0036] For the first guide rail 1a and the second guide rail 1b, there can be multiple specific mounting positions on the mounting frame 1, forming multiple different combinations, meeting the requirements of avoiding interference between the first material table 2 and the second material table 4 during movement. For example, two second guide rails 1b are between two first guide rails 1a.

[0037] Please refer to Figure 2 , in some embodiments, preferably, the first guide rail 1a and the second guide rail 1b are staggered up and down, the sliding connection position of the first material table 2 on the mounting frame 1 is at the lower position of the mounting frame 1, and the sliding connection position of the second material table 4 on the mounting frame 1 is at the upper position of the mounting frame 1. More specifically, the mounting frame 1 includes two vertical support parts 1-1, two connecting parts 1-2 horizontally arranged and fixed between the two support parts 1-1; the two first guide rails 1a are respectively mounted on the bottom surfaces of the two connecting parts 1-2, and the two second guide rails 1b are respectively mounted on the top surfaces of the two connecting parts 1-2.

[0038] With the combination of "staggering the first guide rail 1a and the second guide rail 1b up and down", it is very convenient to select a connection position for the first linear driving mechanism 3 to connect on the first material table 2, and to select a connection position for the second linear driving mechanism 5 to connect on the second material table 4, so that the two connection positions are staggered up and down, and have appropriate setting space.

[0039] Please refer to Figure 1, the table top of the first material table 2 is provided with a plurality of first support rods 2a, and the table top of the second material table 4 is provided with a plurality of second support rods 4a. The first support rod 2a / second support rod 4a is used for placing and limiting the workpiece, and the limiting of the workpiece refers to limiting the movement of the workpiece in the transverse direction and the longitudinal direction. More specifically, the workpiece can be designed with holes, notches, grooves, etc., and the corresponding first support rod 2a / second support rod 4a is inserted to limit the workpiece; or the corresponding first support rod 2a / second support rod 4a can be designed on the edge of the workpiece, and the first support rod 2a / second support rod 4a is higher than the edge of the workpiece, so that the edge of the workpiece is limited.

[0040] Because the bottom surface of the workpiece has various conditions, it can be a plane, a curved surface, or an irregular surface, so the length of the corresponding first support rod 2a / second support rod 4a can be adjusted to adapt to various conditions of the workpiece. The way to adjust the length of the first support rod 2a / second support rod 4a can be to directly replace the first support rod 2a / second support rod 4a of different lengths.

[0041] Please refer to Figure 5 In some embodiments, preferably, the first support rod 2a and the second support rod 4a each include a first section 24-1 and a second section 24-2. The first section 24-1 is used for fixed connection with the first material table 2 / second material table 4. The second section 24-2 is fixedly connected to the first section 24-1 and can be adjusted in height. More specifically, the top of the first section 24-1 is stepped, the bottom of the second section 24-2 has a blind hole for inserting the first section 24-1, a threaded hole communicating with the blind hole, and a screw for fixing the second section 24-2 to the first section 24-1 is threadedly connected in the threaded hole.

[0042] By adopting the mode of “the first support rod 2a and the second support rod 4a each include a first section 24-1 and a second section 24-2”, the length adjustment of the first support rod 2a / second support rod 4a is more simple and fast.

[0043] Please refer to Figure 2 The first linear drive mechanism 3 is installed on the mounting frame 1 and is used to drive the first material table 2 to move between the first position and the second position.

[0044] The second linear drive mechanism 5 is installed on the mounting frame 1 and is used to drive the second material table 4 to move between the first position and the second position.

[0045] When the feeding and discharging table device is in use, at least one mechanical hand is arranged in each of the first position and the second position. Taking the first material table 2 as the feeding table and the second material table 4 as the discharging table as an example, the working steps are as follows:

[0046] S1, the manipulator at the first position places the unprocessed workpiece on the first table 2, and the manipulator at the second position places the processed workpiece on the second table 4;

[0047] S2, the first table 2 and the second table 4 exchange positions;

[0048] S3, the manipulator at the first position takes the processed workpiece from the second table 4, and the manipulator at the second position takes the unprocessed workpiece from the first table 2 and places it in the processing device;

[0049] S4, the first table 2 and the second table 4 exchange positions;

[0050] S5, after the processing device processes the workpiece, the process returns to S1.

[0051] Please refer to Figure 2 and Figure 4 In some embodiments, the first linear drive mechanism 3 and the second linear drive mechanism 5 are both lead screw modules, and the lead screws of the two lead screw modules are driven by the same motor 35a. More specifically, the output shaft of the motor 35a is connected to the input shaft of the reduction box, and the output shaft of the reduction box is connected to one end of one of the lead screws through a shaft coupling.

[0052] The first table 2 and the second table 4 exchange positions, and both move at the same time, in opposite directions and with the same distance. Using two sets of lead screw modules as the first linear drive mechanism 3 and the second linear drive mechanism, and driving / stopping both sets of lead screw modules with the same motor 35a, can easily meet the requirements of the first table 2 and the second table 4 moving at the same time, in opposite directions and with the same distance.

[0053] Please refer to Figure 4 In some embodiments, the lead screws of the two lead screw modules are both fixedly connected with gears 35b, and the two gears 35b are the same and meshed.

[0054] When the motor 35a is started, the lead screws of the two lead screw modules rotate in opposite directions and at the same speed, and the parameters of the two lead screws are also the same, making it more convenient to select the type. The two gears 35b can be fixedly connected to the ends of the lead screws by screws, and when it is necessary to separately adjust the positions of the first table 2 and the second table 4, the fixation between the two gears 35b and the lead screws is released, and the corresponding lead screw is rotated.

[0055] It can be found that, regardless of whether it is in the first position or the second position, the manipulator needs to operate the first table 2 and the second table 4. Because the heights of the first table 2 and the second table 4 are different, if the manipulator at the first position / second position is one, then the manipulator needs two kinds of trajectories, one of which stays at a higher position for the first table 2, and the other of which stays at a lower position for the second table 4.

[0056] Referring to Figure 6 and Figure 7 In some embodiments, the second table 4 is provided with a scissor frame 4b between the table top and the frame. The second table 4 is also provided with a power cylinder 4c. The power cylinder 4c is used to drive the scissor frame 4b to unfold at the loading position and the unloading position, so that the table top of the second table 4 is level with the table top of the first table 2. More specifically, the cylinder body of the power cylinder 4c is hinged to the frame of the second table 4, and the piston rod is hinged to the scissor frame 4b. According to the specific workpiece, the power cylinder 4c can be a pneumatic cylinder or a hydraulic cylinder to meet the support requirements. The frame of the second table 4 and the mounting frame 1 are provided with a drag chain 4e for the power cylinder 4c to run.

[0057] No matter in the first position or in the second position, the robot operates the second table top first to make the table top of the second table 4 level with the table top of the first table 2. In this way, one robot is enough for the first position / second position, and one trajectory can be used to operate the first table 2 and the second table 4.
