Description

Technical Field

[0001] This utility model relates to the field of tray loading equipment technology, specifically to an automatic tray loading equipment for sheet materials. Background Technology

[0002] In the field of display module manufacturing, the tray packaging of sheet products has long relied on manual operation. Although a utility model patent with publication number CN213832332U proposes an automatic tray packaging device for nickel sheets, it still has significant technical limitations. This prior art document discloses a device that uses a servo motor to drive a suction nozzle to move along an X / Y axis guide rail to achieve sheet material handling. Its core structure includes a servo drive unit, linear guide rails, and multiple sets of suction nozzles, aiming to replace traditional manual placement. However, this solution still has the following shortcomings;

[0003] This prior art discloses a device that uses a conveyor belt to transport a nickel sheet tray, an electric suction cup to pick up individual nickel sheets, and loads them one by one into the tray. Its core structure includes a conveyor belt assembly, an electric suction cup driven by a lifting cylinder, a pressure support, and a PLC control system. It aims to replace traditional manual placement; however, this solution still has the following drawbacks:

[0004] First, the electric suction cup can only pick up a single piece of material at a time, and multiple reciprocating movements are required to complete the loading of multiple pieces. The efficiency of picking up and putting in a single time is limited and cannot meet the demand for high production capacity.

[0005] Secondly, the suction cup assembly has a fixed position and can only fit material trays of specific sizes. When dealing with blister boxes of different spacing or specifications, it is necessary to manually disassemble and adjust the position of the suction cup or replace the clamp, which takes a long time and is complicated to operate. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an automatic sheet material loading device, which can effectively solve the problem that the existing technology can only pick up single sheets of material at a time, thus limiting the production capacity.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides an automatic sheet material loading device, comprising:

[0009] A first servo motor and a first support plate, wherein the first servo motor drives the first support plate to move laterally along the X-guide rail via a first lead screw;

[0010] The second servo motor and the second support plate are provided. The second servo motor drives the second support plate to move vertically along the Y-guide rail via the second lead screw.

[0011] Six guide grooves are fixed to the second support plate, and movable bearings are provided in the guide grooves. The movable bearings are fixedly connected to the vertical support rod.

[0012] A horizontal support rod is fixed perpendicularly to the vertical support rod and adsorbs sheet material through an adjustable suction nozzle;

[0013] The air pipe interface controls the suction and release of the nozzle through the cylinder; when the second servo motor drives the second support plate to move up and down, the vertical support rods move synchronously apart or together through the movable bearings arranged at different angles in the guide groove, which is used to adapt to the loading of sheet materials with different spacing and size.

[0014] Preferably, the guide grooves are arranged at different angles, specifically the included angle between adjacent guide grooves is 5°-15°, so that the vertical support rod drives the suction nozzle to form a multi-level adjustable spacing gripping area.

[0015] Preferably, the number of suction nozzles is multiple sets, evenly distributed on the horizontal support rod, and each set of suction nozzles is controlled by an independent air path to achieve synchronous gripping of single or multiple pieces.

[0016] Preferably, the cylinder control includes a positive and negative pressure switching module, which controls the pressure change of the air pipe interface through a solenoid valve to achieve rapid adsorption and release of the sheet material by the suction nozzle.

[0017] Preferably, the first servo motor and the second servo motor are linked by a PLC controller to perform XY axis coordinated motion according to a preset path, thereby completing the automatic transport of the sheet material from the material picking area to the blister box.

[0018] Preferably, there are six guide grooves, symmetrically distributed along the center of the second support plate, with the spacing error between adjacent guide grooves being less than ±0.1mm, to ensure the accuracy of the synchronous operation of multiple suction nozzles.

[0019] Preferably, the horizontal support rod and the vertical support rod are fixed by a threaded locking structure, and the position of the suction nozzle on the horizontal support rod is adjustable within a range of ±10mm to adapt to the adsorption requirements of different sized sheets.

[0020] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0021] 1. Through the coordinated movement of dual servo motors and XY guide rails, combined with the design of synchronous opening and closing of the suction nozzle driven by the change of guide groove angle, the fully automated operation of sheet loading is realized. Compared with the traditional manual method of placing sheets one by one, this equipment can accurately position the transport path through the servo control system, and with the multi-nozzle synchronous adsorption function (supporting up to multiple sheets to be gripped at the same time), it improves work efficiency and completely solves the pain points of low efficiency and high labor intensity of manual labor. In addition, the pneumatically controlled adsorption and release mechanism replaces direct contact with human hands, effectively avoiding problems such as surface scratches and fingerprint pollution caused by finger touch, and significantly reducing the defect rate of finished product appearance.

[0022] 2. Through the mechanical structure of guide groove angle arrangement and linkage with movable bearing, the nozzle spacing is adaptively adjusted. When the servo motor drives the support plate to move up and down, the sliding trajectory of the movable bearing in the guide groove will drive the vertical support rod to move in tandem. Through the angle difference effect, multiple sets of nozzles can be opened or closed synchronously to adapt to various sheet spacing requirements. This avoids the cumbersome operation of changing fixtures in traditional equipment. At the same time, the adjustable nozzle position design and independent air circuit control function further enhance the equipment compatibility. With the real-time calibration of the handling path by the PLC control system, it not only ensures the accuracy of the quantity when picking up and placing multiple sheets, but also eliminates the risk of short loading caused by manual counting.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example: Refer to Figures 1 to 2 An automatic sheet material loading device, comprising:

[0030] The first servo motor 1 and the first support plate 2 are driven by the first lead screw to move the first support plate 2 laterally along the X-guide rail 6.

[0031] The second servo motor 3 and the second support plate 4 are connected by the second lead screw, which drives the second support plate to move vertically along the Y-guide rail 5.

[0032] Six guide grooves 7 are fixed on the second support plate 4. The guide grooves 7 are equipped with movable bearings 8. The movable bearings 8 are fixedly connected to the vertical support rods 9. The second support plate 4 has six guide grooves 7 arranged in a fan shape. The movable bearings 8 are embedded in the grooves and rigidly connected to the vertical support rods 9. When the second support plate 4 moves up and down, the movable bearings 8 slide along the guide grooves 7. Because the guide grooves 7 are arranged at an angle of 5°-15°, the vertical support rods 9 will generate a radial displacement difference at the same time, which will drive the horizontal support rods 10 and the suction nozzles 11 to open or close as a whole, adapting to blister boxes with different spacing.

[0033] A horizontal support rod 10 is fixed perpendicularly to the vertical support rod 9 and adsorbs sheet material through an adjustable suction nozzle 11;

[0034] The air pipe interface 12 controls the suction and release of the suction nozzle 11 via a cylinder; when the second servo motor 3 drives the second support plate 4 to move up and down, the vertical support rod 9 moves synchronously apart or together via the movable bearings 8 arranged at different angles in the guide groove 7, which is used to adapt to the loading of sheet materials of different spacing and size. The first servo motor 1 drives the first support plate 2 to move laterally along the X guide rail 6 via a lead screw, and the second servo motor 3 drives the second support plate 4 to move vertically along the Y guide rail 5 via a lead screw. The linkage of the two sets of motors can accurately position the material picking area or the target position of the blister box.

[0035] Reference Figures 1 to 2 The guide grooves 7 are arranged at different angles, specifically the included angle between adjacent guide grooves 7 is 5°-15°, so that the vertical support rod 9 drives the suction nozzle 11 to form a multi-level adjustable spacing gripping area. The suction nozzle 11 is connected to the cylinder through the air pipe interface 12. The solenoid valve controls the air circuit to switch between positive pressure (release) and negative pressure (adsorption). When picking up the material, the suction nozzle 11 starts negative pressure adsorption after contacting the surface of the sheet material. After being transported to the top of the blister box, it switches to positive pressure release. The whole process is non-contact transfer to avoid human contamination.

[0036] Reference Figures 1 to 2 The number of suction nozzles 11 is in multiple groups, evenly distributed on the horizontal support rod 10. Each group of suction nozzles 11 is controlled by an independent air path to achieve simultaneous gripping of single or multiple pieces. The multiple groups of suction nozzles 11 are evenly distributed on the horizontal support rod 10 and achieve gripping of single pieces or entire rows through independent air path control. The PLC controller calibrates the path according to the preset program to ensure accurate picking and placing of multiple pieces and eliminate the risk of short loading.

[0037] Reference Figures 1 to 2 The cylinder control includes a positive and negative pressure switching module, which controls the pressure change of the air pipe interface 12 through a solenoid valve to realize the rapid adsorption and release of the sheet material by the suction nozzle 11.

[0038] Reference Figures 1 to 2 The first servo motor 1 and the second servo motor 3 are linked by a PLC controller to perform XY axis coordinated motion according to a preset path, so as to complete the automatic transportation of the sheet material from the material picking area to the blister box.

[0039] A PLC (Programmable Logic Controller) is a digital computer specifically designed for industrial control systems. It can automate the control of equipment and machinery in the production process. In use, the first servo motor 1 and the second servo motor 3 are generally controlled by connecting to the servo driver through the output port of the PLC. By sending control signals, the speed, torque, position and other parameters of the motor are adjusted. Its internal program is written based on ladder diagrams or structured text and presets the logic of the sheet material handling path. The PLC sends pulse signals or analog signals to the servo driver to control the speed, direction and displacement of the motor. The first servo motor 1 drives the first support plate 2 to move laterally along the X-axis guide rail 6 via the lead screw. At the same time, the second servo motor 3 drives the second support plate 4 to move vertically along the Y-axis guide rail 5. The coordinated movement of the two axes is achieved through linear interpolation algorithm.

[0040] Reference Figures 1 to 2 There are six guide grooves 7, which are symmetrically distributed along the center of the second support plate 4. The distance error between adjacent guide grooves 7 is less than ±0.1mm to ensure the accuracy of the synchronous operation of the multiple suction nozzles 11.

[0041] Reference Figures 1 to 2 The horizontal support rod 10 and the vertical support rod 9 are fixed by a threaded locking structure. The position of the suction nozzle 11 on the horizontal support rod 10 is adjustable within a range of ±10mm to adapt to the adsorption needs of different sized sheets.

[0042] The working principle of this utility model is as follows:

[0043] The equipment achieves automatic handling and tray loading of sheet materials through the linkage of dual servo motors. The first servo motor 1 drives the first support plate 2 to move laterally along the X-guide rail 6 via a lead screw to complete the horizontal positioning. The second servo motor 3 drives the second support plate 4 to move vertically along the Y-guide rail 5 via a lead screw to achieve vertical lifting. The second support plate 4 is provided with 6 (see figure) guide grooves 7 arranged at different angles. The movable bearing 8 in the groove is fixed to the vertical support rod 9. The horizontal support rod 10 is fixed at 90° perpendicular to the vertical support rod 9. The suction nozzle 11 is adjustable in position and installed at the end of the horizontal support rod 10.

[0044] When the second support plate 4 moves up and down, the movable bearing 8 slides along the guide groove 7. Due to the angle difference of the guide groove 7, the vertical support rod 9 drives the horizontal support rod 10 and the suction nozzle 11 to open or close synchronously (the guide grooves 7 are arranged at different angles (adjacent included angles of 5°-15°), forming a radial distribution). When the second support plate 4 moves up and down; when moving upward, the movable bearing 8 slides upward along the guide groove 7. Because the guide groove is tilted outward (the angle is positive), the movable bearing 8 moves outward (radially outward) while moving upward → driving the vertical support rod 9 to expand outward → the horizontal support rod 10 extends outward accordingly, and the spacing of the suction nozzles 11 increases (expands); when moving downward, the movable bearing 8 slides downward along the guide groove 7. Because the guide groove is tilted inward, the movable bearing 8 moves radially towards the center while moving downward → driving the vertical support rod 9 to retract towards the center → The horizontal support rod 10 moves towards the center, and the gap between the suction nozzles 11 decreases (closes), thus adapting to the needs of blister boxes with different gaps. The suction nozzles 11 are connected to the cylinder through the air pipe interface 12. By controlling the air circuit to switch between positive and negative pressure, the suction, gripping and release of the sheet material is realized. This design combines mechanical linkage and pneumatic control to complete the synchronous handling and precise tray loading of multiple sheets, replacing manual operation, significantly improving efficiency and reducing the risk of contamination.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
