DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-2, a glass feeding robot for a glass screen printing machine includes a transfer mechanism, which is located between a glass sheet carrying lifting platform 13 and a receiving conveyor 9. The glass sheet carrying lifting platform 13 of the device can gradually push the stacked glass sheets upward as the glass sheets are taken away. For example, a support plate is provided, and the glass sheets 12 are stacked on the support plate. The support plate is installed on a vertically arranged lifting mechanism. The lifting mechanism can be a power lifting element such as a ball screw lifting, an electro-hydraulic push rod lifting, etc. Every time a piece of glass is taken away, the support plate rises to a height of the thickness of a piece of glass, ensuring that each time a piece of glass is taken out, The heights of the positions are the same, the transfer mechanism includes a frame 7, a limiting rail 14 fixed to the frame 7, a translation mechanism is installed on the frame 7, the translation mechanism includes a moving block 5 that can move horizontally, a hard pipe 4 that can slide up and down is inserted through the moving block 5, a gripper assembly that can pick up the glass piece is installed at the lower part of the hard pipe 4, a limiting member 10 is installed in the middle part of the hard pipe 4, the limiting member 10 is slidably installed and limited in the limiting rail 14, the limiting rail 14 includes an ascending rail 15 located above the glass piece carrying lifting platform 13, a transition rail 16, and a descending rail 17 located above the receiving conveyor 9.

[0020] When the device is working, the moving block 5 is moved left and right through the translation mechanism. Since the hard tube 4 is vertically arranged and slidably connected with the moving block 5, and the limit piece 10 in the middle of the hard tube 4 slides and is limitedly installed with the limit track 14, when the moving block 5 moves left and right, the hard tube follows the moving block 5 to translate together and the two slide relative to each other. Under the action of the limit track 14, the gripper assembly at the lower part of the hard tube can follow the ascending track 15, the transition track 16, and the descending track 17 to move up and down. When the hard tube 4 moves from the transition track 16 to the position of the ascending track 15, the gripper assembly moves downward to grab the glass piece, and then the hard tube 4 moves to the right, first ascending, then moving horizontally, and then descending on the descending track 17 to release the glass piece to the receiving conveyor 9.

[0021] This device replaces the traditional power telescopic parts responsible for lifting movement through mechanical structures such as the limit rail 14, the hard tube 4, the moving block 5, and the limit member 10. This device only needs to control the left and right movement of the moving block 5 to complete the rising, translation, and lowering actions of the gripper assembly, which is easier to control.

[0022] In one embodiment of the translation mechanism, the translation mechanism includes a power telescopic cylinder that is horizontally arranged and fixed to the frame 7, and the telescopic end of the power telescopic cylinder is fixed to the moving block 5. The moving block 5 is driven to translate by a pneumatic cylinder or a hydraulic cylinder, an electro-hydraulic push rod, etc.

[0023] Another embodiment of the translation mechanism includes a screw rod 6 that is horizontally arranged and rotatably connected to a frame 7, a moving block 5 is threadedly connected to the screw rod 6, and a rotating motor 8 that can drive the screw rod 6 to rotate and reverse is installed on the frame 7. The screw rod 6 is driven to operate by the forward or reverse movement of the rotating motor 8, and the moving block 5 is translated under the action of the thread.

[0024] In one implementation of the limiting member, the limiting member 10 is a rod body which is horizontally arranged and fixedly connected to the hard tube 4 , and the rod body is limited in the limiting track 14 , and is limited in the ascending track 15 , the transition track 16 , and the descending track 17 through the rod body.

[0025] Another implementation method of the limiter, the limiter 10 includes a roller with a horizontally arranged axis, the roller is rotatably connected to the hard tube 4, the roller is limited in the limit track 14, and the roller is limited in the ascending track 15, the transition track 16, and the descending track 17, so that the hard tube can follow the translation of the moving block and move up and down.

[0026] refer to Figure 2 The limiting track 14 includes an upper rod 141 and a lower rod 142 arranged in parallel, and a spacing space is left between the upper rod 141 and the lower rod 142. The limiting member 10 is limited in the spacing space between the upper rod 141 and the lower rod 142. This type of limiting track has a simple structure, is easy to manufacture and use, and has low cost.

[0027] The gripper assembly includes a rubber suction nozzle 11 fixed at the bottom end of the hard tube 4. The hard tube 4 has an air flow channel connected to the rubber suction nozzle 11. The hard tube 4 is connected to the suction device 100. The suction device 100 generates negative pressure suction, so that the air flow channel of the hard tube 4 forms a negative pressure. When the rubber suction nozzle 11 abuts against the glass sheet, the negative pressure suction causes the glass sheet to be adsorbed onto the rubber suction nozzle 11, completing the glass sheet removal. When the glass sheet needs to be released, the negative pressure suction is disconnected, the suction disappears, and the glass sheet is released.

[0028] refer to Figure 1 The suction device 100 includes a negative pressure suction source 1, an electromagnetic three-way valve 2, and a hose 3. The suction end of the negative pressure suction source 1 is connected to the first port of the electromagnetic three-way valve 2, the second port of the electromagnetic three-way valve 2 is connected to the outside, and the third port of the electromagnetic three-way valve 2 is connected to the hard tube 4 through the hose 3. The negative pressure suction source 1 generates negative pressure suction, and the on and off of each port is controlled by the electromagnetic three-way valve 2. When the first port is connected to the third port, the hard tube 4 absorbs the glass, and when the second port is connected to the third port, the glass is released.

[0029] The negative pressure suction source 1 can generate negative pressure suction in the form of a negative pressure generator connected to a positive pressure gas source, such as a vacuum generator in the prior art.

[0030] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technical solution, concept, and design obtained by equivalent replacement or change based on the technical solution and utility model concept of the utility model by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
