[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0040] like Figures 1-6As shown, this utility model provides an automatic positioning and feeding device, which includes: a frame 1, on which a worktable 10 is provided; an X-axis linear module 11, mounted on the worktable 10, with a positioning mechanism 2 installed at the moving end of the X-axis linear module 11, the positioning mechanism 2 including a base plate 20 and a support plate 21 mounted on the base plate 20, with drive cylinders 22 mounted on the base plate 20 along the X-axis and Y-axis directions respectively, and the telescopic ends of the two sets of drive cylinders 22 respectively connected to positioning columns 220, the positioning columns 220 extending upward through the support plate 21; positioning blocks 210 are provided on the two sides of the support plate 21 away from the two sets of positioning columns 220; a material tray conveyor line 3, mounted parallel to the X-axis linear module 11 on the worktable 10; a tray separating mechanism 30 is installed at one end of the material tray conveyor line 3, and a tray stacking mechanism 31 is installed at the other end; and a feeding mechanism 4, mounted above the material tray conveyor line 3, for transferring the material in the tray to the positioning mechanism 2.

[0041] The automatic positioning and feeding device provided by this utility model places a number of trays carrying workpieces 23 on a tray-splitting mechanism 30. The tray-splitting mechanism 30 lowers the trays carrying workpieces 23 one by one onto the tray conveyor line 3, which transports them to the bottom of the feeding mechanism 4. The feeding mechanism 4 then sequentially transports the workpieces 23 in the trays onto the support plate 21 of the positioning mechanism 2. Since there may be a positional deviation of the workpieces 23 placed on the support plate 21 by the feeding mechanism 4, the drive cylinders 22 on the X-axis and Y-axis of the base plate 20 simultaneously drive the positioning column 220 to move and push the workpieces 23 to be positioned. Finally, the positioning mechanism 2 is driven by the X-axis linear module 11 to move the positioned workpieces 23 to the target station for subsequent processing or assembly. Empty trays on the tray conveyor line 3 are transported toward the stacking mechanism 31 and are stacked and collected by the stacking mechanism 31. This automatic positioning and feeding device can realize automatic feeding and automatic positioning of workpieces 23, improving the accuracy, stability and production efficiency of workpieces 23 in processing or assembly at each station.

[0042] Specifically, such as Figure 2 As shown, the support plate 21 is mounted on top of the base plate 20 by four support columns. The support plate 21 near the positioning column 220 has clearances for avoiding the positioning column 220. Positioning blocks 210 are arranged on the top surface of the support plate 21 along the X and Y axes. In this embodiment, four positioning blocks 210 are preferred, dividing the support plate 21 into two positioning areas. Two sets of drive cylinders 22 are respectively provided on the base plate 20 along the X and Y axes, meaning that two workpieces 23 can be positioned simultaneously. It should be noted that the number of drive cylinders 22 and positioning areas on the support plate 21 can be increased according to production needs to improve production efficiency.

[0043] In this embodiment, as Figure 3As shown, the tray-separating mechanism 30 includes a base disposed within the frame 1, on which a second lifting cylinder 302 is mounted. The telescopic end of the second lifting cylinder 302 is connected to a first lifting cylinder 301. The telescopic end of the first lifting cylinder 301 is horizontally mounted with a first lifting plate 303. Limiting cylinders 304 are respectively mounted on the base on the left and right sides of the second lifting cylinder 302. The telescopic ends of the limiting cylinders 304 are connected to vertically upward limiting brackets 305. A slide rail and a slider are provided between the bottom of the limiting brackets 305 and the base. Two limiting blocks 306 are mounted on the top of the limiting brackets 305. In the above structure, by placing a tray carrying workpieces 23 on the four limiting blocks 306, when it is necessary to feed the tray to the tray conveyor line 3, the first lifting cylinder 301... Simultaneously, the second lifting cylinder 302 drives the first lifting plate 303 upward to move all the material trays upward. At this time, the two limiting cylinders 304 simultaneously drive the limiting brackets 305 to move away from the material trays to provide clearance when the material trays descend. The first lifting cylinder 301 drives the first lifting plate 303 to move all the material trays downward to the target distance. The two limiting cylinders 304 simultaneously drive the limiting brackets 305 to move towards the sides of the two trays and engage the four limiting blocks 306 at the bottom of the penultimate material tray. Finally, the second lifting cylinder 302 retracts, lowering the material trays on the first lifting plate 303 to the material tray conveyor line 3 for conveying. This structure enables the material trays to be lowered automatically, saving the cost of manual operation and improving the efficiency of material unloading.

[0044] Furthermore, such as Figure 4 As shown, the stacking mechanism 31 includes a support plate mounted on the workbench 10. A third lifting cylinder 310 is installed on the side of the support plate. The telescopic end of the third lifting cylinder 310 is horizontally connected to a second lifting plate 311. Two sets of one-way limiting components 32 are symmetrically installed on the left and right crossbeams of the tray conveyor line 3. After the workpieces 23 in the trays on the tray conveyor line 3 are transferred, the tray conveyor line 3 transports the empty trays toward the stacking mechanism 31 to the top of the second lifting plate 311. The third lifting cylinder 310 drives the second lifting plate 311 to drive the empty trays on the tray conveyor line 3 to move upward. At this time, the empty trays pass through the one-way limiting components 32 and are supported on the four one-way limiting components 32. This is repeated to collect the empty trays in a stacking manner, so that the empty trays can be automatically collected, saving the cost of manually collecting empty trays and improving the collection efficiency of empty trays.

[0045] Specifically, such as Figure 5As shown, the unidirectional limiting assembly 32 includes a support bracket 320, a "U"-shaped base 321, a locking block 322, and an abutment block 323. One end of the support bracket 320 is connected to the crossbeam of the tray conveyor line 3, and the other end extends outward. The "U"-shaped base 321 is installed on the top of the extended end of the support bracket 320. One end of the locking block 322 is rotatably connected to the opening of the "U"-shaped base 321 via a pin, and the other end extends toward the tray conveyor line 3. The abutment block 323 is installed on the top of the "U"-shaped base 321 and on the side away from the tray conveyor line 3. The bottom of the locking block 322 is inclined, so that when the empty tray moves upward, it first abuts against the bottom of the locking block 322. The extended end of the locking block 322 rotates upward to provide clearance for the empty tray. When the empty tray moves above the locking block 322, the third lifting cylinder 310 moves downward, and the empty tray falls onto the four locking blocks 322 for collection. Due to the setting of the abutment block 323, when the locking block 322 is subjected to the downward pressure of the empty tray, the tail end of the locking block 322 will abut against the bottom of the abutment block 323, thereby restricting the downward rotation of the locking block 322. Furthermore, in order to ensure that the trays can be orderly placed, collected, and transported on the tray distribution mechanism 30, the tray stacking mechanism 31, and the tray conveyor line 3, multiple guide members 33 are respectively provided on the four circumferential crossbeams of the tray conveyor line 3.

[0046] In this embodiment, as Figure 1 As shown, the feeding mechanism 4 includes a Y-axis linear module 40 mounted above the material tray conveyor line 3 and a Z-axis linear module 41 mounted on the moving end of the Y-axis linear module 40. The moving end of the Z-axis linear module 41 is provided with a material picking component 42. The Y-axis linear module 40 and the Z-axis linear module 41 are respectively driven by a lead screw to improve the handling accuracy and handling efficiency of the workpiece 23.

[0047] Furthermore, such as Figure 6As shown, the material handling assembly 42 has two sets, and the two sets of material handling assemblies 42 are arranged on the same axis. Specifically, the moving end of the Z-axis linear module 41 is equipped with a connecting plate 420. The material handling assembly 42 includes an adjusting plate 421 installed at the bottom of the connecting plate 420. The adjusting plate 421 is provided with multiple adjusting holes 422. The bottom of the adjusting holes 422 is respectively connected to a "Z"-shaped bracket 423, and a suction nozzle 424 is installed at the bottom of each "Z"-shaped bracket 423. By adjusting the "Z"-shaped bracket 423 on the adjusting holes 422, the multiple suction nozzles 424 can move at different coordinates. The feeding mechanism 4 is adapted to handle different specifications and models of workpieces 23 for picking and unloading, increasing its applicability. Furthermore, a sliding cylinder 425 is provided on one side of the connecting plate 420. One set of picking components 42 is connected to the bottom of the connecting plate 420, and the other set of picking components 42 is connected to the slider of the sliding cylinder 425. In this structure, the distance between the two picking components 42 can be adjusted by the setting of the sliding cylinder 425, which improves the ability of the picking components 42 to pick up and unload workpieces 23 of different specifications and workpieces 23 with different spacing on the tray.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
