[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0028] Reference Figures 1-6An automatic tray loading machine for keyboard keys includes a frame 1, on which a tray loading unit 2, a six-axis robot handling unit 3, a tray positioning fixture 4, a tray loading and unloading assembly line 5, and an electrical control box 6 are mounted. The electrical control box 6 is mounted on the frame 1.

[0029] Tray loading unit 2 includes an empty tray loading line 21, a full tray unloading line 22, an empty tray lifting mechanism 23, an empty tray sorting unit 24, a positioning unit 25, and an empty tray error-proofing detection mechanism 26. The empty tray loading line 21 is connected to a six-axis robot handling unit 3, and the full tray unloading line 22 is also connected to the six-axis robot handling unit 3. The empty tray lifting mechanism 23 is located below the empty tray loading line 21. The empty tray sorting unit 24 and the positioning unit 25 are located at the discharge end of the empty tray loading line 21, and the empty tray error-proofing detection mechanism 26 is located on one side of the empty tray sorting unit 24 and the positioning unit 25.

[0030] The six-axis robot handling unit 3 includes a six-axis robot 31 and a robot picker 32. The six-axis robot 31 is mounted on the frame 1, and the robot picker 32 is mounted on the end of the robotic arm of the six-axis robot 31.

[0031] Tray positioning fixture 4 is mounted on frame 1 and is located within the working range of six-axis robot 31.

[0032] The empty tray splitting unit 24 includes front and rear splitting cylinders 241, a rear splitting plate 242, and a front splitting mechanism 243. The positioning unit 25 includes a side positioning mechanism 251 and a side positioning plate 252. The front and rear splitting cylinders 241 are connected to the rear splitting plate 242, the front splitting mechanism 243 is connected to the side positioning mechanism 251, and the side positioning mechanism 251 is connected to the side positioning plate 252.

[0033] The front and rear splitting cylinders 241 drive the splitting sheet metal to insert into the front and rear handles of the Tray, preventing the six-axis robot 31 from stacking materials during material handling. The Tray side positioning cylinder drives the side positioning plate 252 to push the Tray forward to the side baffle to position the side of the Tray. The front splitting mechanism 243 pushes the Tray forward until it reaches the Tray front baffle, positioning the Tray in the front and rear directions.

[0034] The empty tray foolproof detection mechanism 26 includes a first micro switch 261 and a front push cylinder 262, with the first micro switch 261 connected to the front push cylinder 262.

[0035] After an empty tray is placed on the tray positioning fixture 4, if the empty tray is oriented correctly, the forward-pushing cylinder 262 will push the first microswitch 261 forward to detect the tray, and the first microswitch 261 will output a signal. After the six-axis robot 31 picks up the tray, it can place it on the tray positioning fixture 4 without rotating. However, if the forward-pushing cylinder 262 pushes the first microswitch 261 forward and there is no signal output, it means that the tray is placed in the opposite direction to the required orientation of the tray on the tray positioning fixture 4, i.e., the placement orientation is incorrect. After picking up the tray, the six-axis robot 31 needs to rotate 180° before placing it on the tray positioning fixture 4.

[0036] Tray positioning fixture 4 includes multiple Tray positioning blocks 41, Tray bottom pad 42, and a second micro switch 43. The Tray positioning blocks 41 and the second micro switch 43 are disposed on the Tray bottom pad 42.

[0037] The error-proofing test is performed again by the signal feedback of the second micro switch 43 to check whether the tray is placed in the specified orientation. This determines the orientation of the tray after the six-axis robot 31 picks up the tray and places it on the full tray unloading line 22. The detection principle is the same as above.

[0038] Trays come in various sizes, namely 490mm*180mm, 355mm*165mm and 385mm*140mm. The upper surface of the tray has two first grooves on both sides, which are symmetrically distributed. The upper surface of the tray has two second grooves and three second grooves equidistantly distributed on the upper and lower sides, respectively.

[0039] The stacks of empty trays are manually placed on the empty tray loading line 21. Each stack contains 30 empty trays. As the empty tray loading line 21 operates, the empty tray lifting mechanism 23 will lift multiple empty trays to the loading position in sequence.

[0040] The empty tray splitting unit 24 and positioning unit 25 will split and position the empty tray respectively. The front and rear splitting cylinders 241 drive the splitting sheet metal to insert into the front and rear handles of the tray to prevent stacking. The side positioning plate 252 drives the tray to the side baffle for side positioning. The front splitting mechanism 243 drives the tray to the front baffle for front and rear direction positioning.

[0041] The photoelectric sensor at the empty tray foolproof detection mechanism 26 detects the placement direction of the empty tray. That is, the first micro switch 261 detects the second groove on the surface of the tray. If the second groove is detected, the tray is placed in the correct direction, and the robot picker 32 picks up the tray directly. If the placement direction is incorrect, the second groove cannot be detected, and the robot picker 32 will rotate 180° after picking up the tray before placing it on the tray positioning fixture 4.

[0042] The six-axis robot 31 transports the empty tray from the empty tray loading line 21 to the tray positioning fixture 4, waiting for the robotic arm to place the keyboard keys into the tray.

[0043] After the robotic arm places the keyboard keys into the tray, the six-axis robot transports the full tray from the tray positioning fixture 4 to the full tray unloading line 22. As the full tray unloading line 22 operates, the full trays can be manually removed one by one.

[0044] The upper surface of the empty tray loading line 21 is provided with a blocking component. The blocking component is used to prevent the tray from falling from both sides of the empty tray loading line 21. The blocking component includes multiple side plates 7. Multiple threaded rods 8 are symmetrically and rotatably installed on the front and rear surfaces of the frame 1. The multiple side plates 7 are threadedly sleeved on the multiple threaded rods 8, and their bottoms are all in sliding contact with the upper surface of the empty tray loading line 21.

[0045] The trays to be placed will be located between multiple side plates 7, which can prevent multiple trays from falling off the empty tray loading line 21. At the same time, according to the different sizes of different specifications of trays, the side plates 7 can be moved laterally by rotating the threaded rod 8 to change the distance between multiple side plates 7, so as to meet the limiting and blocking of trays of different specifications and sizes.

[0046] In this invention, the equipment is equipped with components such as a tray loading unit 2, a six-axis robot handling unit 3, a tray positioning fixture 4, and a tray loading and unloading assembly line 5, which realizes automated tray placement by keyboard buttons, improves tray placement efficiency and accuracy, and reduces labor costs.

[0047] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
