Description

Technical Field

[0001] The present invention relates to the field of mechanical processing and parts equipment manufacturing, and in particular to a new type of fully automatic large-scale feeding mechanism used in scenarios where parts and products need to be loaded or fed in an automated manner. Background Art

[0002] The feeding mechanism is a very common and widely used mechanism in the field of parts equipment manufacturing and mechanical processing. It is widely used in automobile, 3C, pharmaceutical and other manufacturing companies. It is constrained by the different requirements of different customers and different products, and has different requirements for feeding time, floor space, cost, etc. However, it is undeniable that the feeding mechanism has a great impact on the promotion of automated production lines and intelligent manufacturing.

[0003] The mainstream feeding methods on the market at present:

[0004] At present, there are many ways for feeding mechanisms to feed materials, but there are not many mechanisms that can be used for pallet feeding. For example, in normal stacking and loading, the pallet is pushed into the loader and waits for the internal manipulator to clamp it. However, the problem with this method is that it will inevitably take up a part of the automatic line time during the loading and unloading process, which is very unfavorable for the production planning of the workshop. Similarly, the feeding time that can be used for larger products will not be very long, and it is necessary to frequently replace pallets or replenish materials. For larger stacking mechanisms, most use robot stacking. Although this method is reliable, this ultra-high load robot still needs to ensure its speed while ensuring accuracy, and its cost is very expensive. In addition, the requirements for floor space are very strict, and it is impossible to achieve large or ultra-large feeding.

[0005] The feeding mechanism is an important mechanism technology for equipment manufacturing factories and parts processing manufacturing industries. It is widely used in many assembly automatic lines and intelligent manufacturing fields. Under the thinking of "Internet + Manufacturing", products need to be customized, and small-batch, customized flexible manufacturing will become the norm. A feeding mechanism is needed that can not only meet the basic performance requirements of the product, but also ensure the quality of the product, improve production efficiency, reduce costs, and realize flexible production of the product.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. Uninterrupted feeding and high working efficiency: The feeding mechanism in the present invention separates the mechanism for loading materials onto the wire body and the mechanism for transferring the internal pallet. The material tray transverse movement mechanism in the present invention is the mechanism for loading materials onto the wire body. The structure is provided with two pallet placement plates, which can alternately feed the wire body, thereby realizing continuous and uninterrupted feeding and improving working efficiency.

[0019] 2. Strong compatibility: The feeding mechanism of the present invention is integrated by separate design, which can adapt to the working environment of different design technical standards.

[0020] 3. High precision: The feeding mechanism of the present invention uses electric cylinders as the transfer and displacement elements. The design of the electric cylinders and guide rails greatly enhances the concentration of pressure release in the linear motion of the device, effectively preventing the displacement force loss in the transfer process, while ensuring the straightness of its motion. The transmission of the servo motor, synchronous belt and guide rails guarantees the economy and precision very well. At the same time, the transmission of the synchronous belt and synchronous wheel increases the flexibility of the mechanism and improves the precision of the feeding mechanism.

[0021] 4. Low cost and controllable: The feeding mechanism of the present invention uses an automated integrated model, and its internal components are highly replaceable, making it easier to control costs. Compared with robots or three-axis manipulators and three-axis or four-axis transfer mechanisms sold as a whole, it has extremely high replaceability, and is also conducive to cost division, making the cost structure more clearly visible.

[0022] 5. Large capacity: Since the feeding mechanism of the present invention uses pallets as the stacking base, its storage capacity can be larger under the same stacking conditions. Its storage capacity can be used as a reference for the actual use of pallets in the factory. The larger storage capacity can reduce the number of times employees change materials and extend the use time of each replenished material. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0029] like Figure 1As shown, the present invention provides a new type of fully automatic large-scale feeding mechanism, including a frame 1, a three-axis transfer structure and a material tray transverse movement structure provided with a guide rail E4 and two tray placement plates 30. The three-axis transfer structure is installed on the frame 1, and the tray placement plate 30 moves along the guide rail E4. The two tray placement plates 30 alternately feed the line body, realizing continuous and uninterrupted feeding.

[0030] like Figure 2 As shown, the three-axis transfer structure includes an x-axis transfer unit, a y-axis transfer unit and a z-axis transfer unit. The x-axis transfer unit is slidably connected to the y-axis transfer unit, and the y-axis transfer unit is slidably connected to the z-axis transfer unit.

[0031] The x-axis transfer unit includes a driving subunit B and a pair of guide rail slider subunits B. The driving subunit B includes a synchronous toothed belt B24, a servo motor B25, a reducer B26, a bearing 27, a transmission rod 28, a transmission base plate 29, and a synchronous wheel B31. The reducer B26 and the transmission rod 28 are both fixed on the transmission base plate 29. The input end of the reducer B26 is connected to the servo motor B25, and the output end is connected to the transmission rod 28 through a gear pair.

[0032] The servo motor B25 drives the transmission rod to rotate through the reducer B26 and the gear pair. The reducer increases the torque while reducing the speed, ensuring the output force, thereby achieving an ideal driving effect. While the force and torque during transmission through the gear pair are guaranteed, the required accuracy can also be obtained through different gears.

[0033] Both ends of the transmission rod 28 are connected to the synchronous wheel B31 through the bearing 27. The bearing 27 is installed in the bearing mounting support. The synchronous wheel B31 and the synchronous toothed belt B24 form a synchronous belt transmission line along the x-axis direction.

[0034] The guide rail slider subunit includes a guide rail base plate B6, a guide rail B7 installed on the guide rail base plate B6, a guide rail base plate C21, a guide rail C22 installed on the guide rail base plate C21, and a slider 32 slidingly connected to the guide rail C22. The slider 32 is also fixedly connected to the synchronous toothed belt B24, and the synchronous toothed belt B24 drives the slider 32 to move along the guide rails B7 and C22.

[0035] The y-axis transfer unit includes a driving subunit A and a guide rail slider subunit A. The driving subunit A includes a reducer A8, a servo motor A9, a synchronous wheel A10 and a synchronous toothed belt A12. The input end of the reducer A8 is connected to the servo motor A9, and the output end is connected to the synchronous wheel A10. The synchronous wheel A10 and the synchronous toothed belt A12 form a synchronous belt transmission line. The guide rail slider subunit A includes a guide rail base plate A13, a guide rail A11 installed on the guide rail base plate A13, and a yz-axis transfer unit connecting plate 16 slidably connected to the guide rail A11. The guide rail base plate A13 is fixedly connected to the slider 32, and the yz-axis transfer unit connecting plate 16 is fixedly connected to the synchronous toothed belt A12. The z-axis transfer unit can move along the y-axis direction through the yz-axis transfer unit connecting plate 16, and the y-axis transfer mechanism can move along the x-axis direction along the guide rail B7 and the guide rail C22, so the z-axis transfer unit can complete the movement in the xy-axis direction.

[0036] The z-axis transfer unit includes a guide rail connecting plate 17 fixedly connected to the yz-axis transfer unit connecting plate 16, a guide rail mounting plate A15 fixed on the guide rail connecting plate 17, a guide rail D14 mounted on the guide rail mounting plate A15, an electric cylinder 18 fixed on the guide rail connecting plate 17, a guide rail mounting plate B19, a connecting block 20 and a clamping subunit. One end of the guide rail mounting plate B19 is connected to the slide table of the electric cylinder 18, and the other end is connected to the clamping subunit through the connecting block 20. A guide rail matching the guide rail D14 is also installed on the guide rail mounting plate B19, and the guide rail mounting plate A15 and the guide rail mounting plate B19 are slidably connected through this pair of matching guide rails.

[0037] The clamping subunit includes a clamping connection plate 23, a cylinder, a clamping subunit guide rail and a clamping claw. The cylinder, the clamping subunit guide rail, the clamping claw and the sensor are all installed on the clamping connection plate 23. The clamping claw is fixedly connected to the piston of the cylinder. The cylinder can be two one-way cylinders or a two-way cylinder, which can realize the clamping action of the clamping claw. The clamping claw moves along the clamping subunit guide rail following the piston when the cylinder is extended or retracted.

[0038] The gripping subunit is also provided with two sensors, one for detecting whether the gripping claws have completed the gripping action, and the other for detecting whether the material box contains material.

[0039] like Figure 3 As shown, the tray transverse movement structure also includes a rodless cylinder 2, a transverse movement table panel 3 and a rodless cylinder connecting plate 5. The rodless cylinder 2 and the guide rail E4 are both installed on the transverse movement table panel 3, the tray placement plate 30 is fixedly connected to the rodless cylinder connecting plate 5, the rodless cylinder connecting plate 5 is fixedly connected to the slide of the rodless cylinder 2, and the rodless cylinder connecting plate (5) is slidably connected to the guide rail E4.

[0040] It should be noted that the material trays and empty material trays in the present invention are stacked in the material box and empty material box storage area by means of pallets. By stacking by pallets, under the same stacking conditions, the storage capacity of the mechanism is larger.

[0041] The specific operation process of this organization is as follows:

[0042] First, the x-axis transfer structure and the y-axis transfer structure move the z-axis transfer structure to above the material box, then the z-axis transfer structure moves down, and the pallet is clamped using the clamping subunit, then the z-axis transfer unit rises, the x-axis transfer structure and the y-axis transfer structure move the z-axis transfer structure to the pallet placement plate 30 of the material tray transverse movement structure, the clamping subunit is released, the pallet is placed, and then the material tray transverse movement structure moves the pallet placement plate 30 on which the material tray is placed to the middle position.

[0043] After the material tray reaches the middle position, it will feed the line body. At the same time, the x-axis transfer structure and the y-axis transfer structure move to the clamping position again, and the z-axis transfer structure clamps again, and then places the clamped tray on another tray placement plate 30.

[0044] When the tray at the middle position is empty, the tray lateral movement structure moves the tray that was clamped for the second time to the middle position to continue feeding the line. At this time, the x-axis transfer structure, the y-axis transfer structure and the z-axis transfer structure operate to clamp the empty tray and transfer it to the empty tray placement area, and then clamp the tray to the empty tray placement plate 30. This cycle is repeated to achieve continuous and uninterrupted feeding, greatly improving work efficiency.

[0045] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
