Description

Technical Field

[0001] The present invention is applied to the technical field of product feeding, and particularly relates to a continuous feeding mechanism for a magazine. Background Art

[0002] Optical lenses are essential components in machine vision systems, which directly affect the quality of imaging and the implementation and effect of algorithms. In the optical lens assembly process of electronic products such as mobile phones and tablets, the tray containing lenses is generally first transported to the assembly station through a conveying mechanism, and then the lenses on the tray are installed in the lens barrel by a manipulator. When the lenses on the tray are used up, the conveying mechanism will transport the empty tray back to the loading station, and then the tray will be transported back to the assembly station after it is filled with lenses. However, loading requires a relatively long waiting time and a slow feeding speed, resulting in low assembly efficiency of the product, which is not suitable for mass production in factories. If a continuous feeding mechanism with a simple structure, fast feeding speed, and greatly improved work efficiency can be designed, the above problems can be solved well. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a magazine continuous feeding mechanism which has a simple structure, a fast feeding speed and can greatly improve the working efficiency.

[0004] The technical solution adopted by the present invention is: the present invention includes a material magazine feeding and recovery module, a material tray transfer module and a material tray moving module, the material magazine feeding and recovery module includes a mounting frame and two groups of material magazine lifting components, the two groups of material magazine lifting components are both arranged on the mounting frame, the movable end of the material magazine lifting component is provided with a limiting tray adapted to the loading material magazine, the material tray transfer module includes a linear moving mechanism and a material tray carrier, the material tray carrier is connected to the movable end of the linear moving mechanism through a rotating mechanism, and the active end of the material tray moving module is adapted to the material tray on the loading material magazine.

[0005] It can be seen from the above scheme that the two groups of magazine lifting assemblies are respectively the first lifting assembly and the second lifting assembly, and the two loading magazines are respectively the first magazine and the second magazine. The first magazine is equipped with a plurality of first material trays, and the second magazine is equipped with a plurality of second material trays. Firstly, the tray moving module drags the trays of the first magazine and the second magazine onto the tray carrier, and the external manipulator takes out the lenses on the first tray and performs material retrieval and assembling operations. When all the lenses on the first tray are taken out, the external manipulator continues to take out the lenses on the second tray. At this time, the tray moving module pushes the first tray that has been taken out back to the first magazine. Driven by the first lifting assembly, the first magazine rises a certain distance, and the tray moving module drags another first tray full of lenses onto the tray carrier. When all the lenses on the second tray are taken out, the external manipulator continues to take out the lenses on the second tray. After all the lenses are taken, the external manipulator takes the first tray full of lenses, and the tray moving module pushes the second tray full of lenses back to the second magazine. Driven by the second lifting component, the second magazine rises a certain distance, and the tray moving module drags another second tray full of lenses to the tray carrier. In this cycle, the supply of full trays and the recovery of empty trays are completed at the same time, thereby realizing the alternating feeding of the two loading magazines. There is no need to waste waiting time, the feeding speed is fast, and the assembly efficiency of the product is greatly improved. It is suitable for mass production in factories. In addition, the drive of the linear moving mechanism can drive the tray to move to the specified position, and the drive of the rotating mechanism can adjust the feeding position of the tray, thereby realizing precise feeding.

[0006] A preferred solution is that the limit tray includes a support seat, a limit seat and a clamping module, the support seat is arranged at the movable end of the magazine lifting assembly, the limit seat is arranged on the support seat, the limit seat is provided with a limit groove adapted to the loading magazine, the clamping module is arranged on the limit seat, and the active end of the clamping module is arranged opposite to the loading magazine.

[0007] It can be seen from the above scheme that the loading magazine is adapted in the limiting groove, ensuring the accurate position of the loading magazine. The loading magazine is pressed against the limiting seat by the drive of the clamping module, avoiding the problem of shaking or displacement of the loading magazine when the tray moving module pushes and pulls the tray.

[0008] A preferred solution is that the clamping module includes a cylinder and a pressure block, the cylinder is arranged on the lower end surface of the limit seat, the pressure block is connected to the output end of the cylinder, and the side of the limit seat is provided with a clearance groove, and the pressure block is fitted in the clearance groove and pressed on the loading magazine.

[0009] It can be seen from the above scheme that the pressing block is pressed tightly on the loading magazine by the drive of the cylinder, so as to avoid the problem of shaking or deviation of the loading magazine when the tray moving module pushes and pulls the tray.

[0010] A preferred solution is that a plurality of positioning pins are provided on the limiting seat, the positioning pins are located in the limiting grooves, a positioning hole is provided on the loading magazine, and the positioning pins are matched with the positioning hole.

[0011] It can be seen from the above solution that when the loading magazine is placed on the limiting seat, the positioning pin on the limiting seat is adapted to the positioning hole of the loading magazine to ensure that the loading magazine is accurately positioned.

[0012] A preferred solution is that the rotating mechanism includes a base and a rotating platform, the base is arranged at the movable end of the linear moving mechanism, the rotating platform is arranged on the base, and the material tray carrier is arranged at the movable end of the rotating platform.

[0013] It can be seen from the above scheme that the position of the tray carrier can be adjusted by driving the rotating platform, thereby realizing the position adjustment of the tray.

[0014] A preferred solution is that the tray carrier is provided with two positioning grooves, and the positioning grooves are adapted to the tray.

[0015] It can be seen from the above solution that the material tray is fitted into the positioning groove to ensure that the position of the material tray is accurate.

[0016] A preferred solution is that two elastic positioning mechanisms are provided on the tray carrier, and the elastic positioning mechanisms are located on the sides of the positioning groove. The elastic positioning mechanisms include a mounting seat, a floating seat, a rolling bearing and two guide components. The mounting seat is provided on the tray carrier, and the floating seat is connected to the mounting seat through a plurality of springs. The rolling bearing is provided on the floating seat. When the tray is adapted in the positioning groove, the tray contacts the rolling bearing. The guide component includes a linear bearing and a guide shaft. The linear bearing is provided on the mounting seat, and the guide shaft is provided on the floating seat. The guide shaft is slidably fitted in the linear bearing.

[0017] It can be seen from the above scheme that when the tray moving module drags the tray out to the tray carrier, the rolling bearing rolls on the side of the tray to prevent the tray from being scratched. Finally, the tray fits into the positioning groove. At this time, under the reaction force of several springs, the rolling bearing will press the tray to avoid shaking or displacement of the tray during operation.

[0018] A preferred solution is that a fixed block is provided on the base, two slot-type photoelectric sensors are provided on the fixed block, a fixed plate is provided on the tray carrier, a first sensing plate and a second sensing plate are provided on the fixed plate, and the first sensing plate and the second sensing plate are respectively adapted to the grooves on the two slot-type photoelectric sensors.

[0019] It can be seen from the above scheme that the two slot-type photoelectric sensors are the first sensor and the second sensor. Under the drive of the rotating platform, the tray carrier rotates clockwise at a certain angle. When the first sensing piece fits into the groove of the first sensor, the first sensor transmits a sensing signal to the external controller, and the controller controls the rotating platform to stop driving, indicating that the tray has reached the limit position; under the drive of the rotating platform, the tray carrier rotates clockwise at a certain angle. When the second sensing piece fits into the groove of the second sensor, the second sensor transmits a sensing signal to the external controller, and the controller controls the rotating platform to stop driving, indicating that the tray has reached the limit position.

[0021] It can be seen from the above scheme that by driving the rotating platform, the material tray carrier rotates clockwise or counterclockwise at a certain angle. When the screw head of the limit bolt rests on the limit block, the material tray carrier is blocked and stops rotating, indicating that the material tray has reached the limit position.

[0022] A preferred solution is that the loading magazine includes a magazine body and a plurality of material trays, and the plurality of material trays are slidably fitted on the magazine body, and a plurality of through holes are provided on both sides of the magazine body, and support plates are provided on both sides of the support seat, and the magazine body is located between the two support plates, and an infrared transmitter and an infrared receiver are respectively provided on the two support plates, and the transmitting end of the infrared transmitter and the receiving end of the infrared receiver are both arranged opposite to the through holes, and the material tray moving module includes a three-axis linear module and an L-shaped hook plate, and the L-shaped hook plate is arranged at the movable end of the three-axis linear module, and a hook hole is provided on the material tray, and the L-shaped hook plate is adapted to the hook hole.
