Description

Technical Field

[0001] This utility model relates to the field of automated production technology, specifically a multi-station synchronous feeding mechanism. Background Technology

[0002] In automated production lines, the same workpiece often needs to undergo multiple processes, which need to be carried out at different workstations. This necessitates transferring the workpiece between these workstations. With the continuous development of automated production technology, many workpieces require placement at different angles during transfer to accommodate production and processing at different workstations. Currently, many existing automated production lines use drive motors to power belts and connecting rods to drive material handling components for loading and unloading, or use sliding table cylinders to drive material handling components. While these two types of loading devices can meet the needs of automated workpiece handling, they cannot achieve placement of workpieces at different angles during transport. To solve this problem, many manufacturers use robotic arms in conjunction with vision systems to achieve workpiece transfer and placement at different angles. However, robotic arms and vision systems are costly, and their handling efficiency is relatively low.

[0003] Therefore, there is an urgent need for a multi-station synchronous feeding mechanism to solve the above problems. Utility Model Content

[0032] 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.

[0033] 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.

[0034] 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.

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.

[0036] 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.

[0037] like Figure 1-6 As shown, this utility model provides a multi-station synchronous feeding mechanism, which includes: an X-axis linear module 1, with multiple Z-axis linear modules 2 installed in parallel at its driving end; the X-axis linear module 1 is used to drive the multiple Z-axis linear modules 2 to perform synchronous reciprocating motion along the X-axis direction; an "L"-shaped connecting plate 3 is installed at the moving end of the Z-axis linear module 2, and the "L"-shaped connecting plate 3 is parallel to the axis of the Z-axis linear module 2; a vacuum generator 30 is detachably installed at the upper end of the "L"-shaped connecting plate 3, and a hollow rotary motor 31 is installed at its bottom end; the hollow shaft of the hollow rotary motor 31 is rotatably connected to the vacuum generator 30 at its upper end, and a suction nozzle 32 is installed at its bottom end; wherein, both the X-axis linear module 1 and the Z-axis linear module 2 adopt a lead screw drive structure.

[0038] This utility model provides a multi-station synchronous feeding mechanism. An X-axis linear module 1 drives a Z-axis linear module 2 to move the workpiece held by the suction nozzle 32 left and right. The Z-axis linear module 2 drives a hollow rotary motor 31 to move the workpiece held by the suction nozzle 32 up and down. The hollow rotary motor 31 drives the workpiece held by the suction nozzle 32 to rotate at any angle. This allows the workpiece to be placed at different angles during transfer, satisfying the production and processing needs of workpieces at different stations. The screw-driven structure enables precise workpiece handling, and the multi-station structure improves workpiece handling efficiency.

[0039] In this embodiment, as Figure 1-3 As shown, the X-axis linear module 1 includes a base plate 10 and a first drive motor 11 mounted on one side of the base plate 10. The first drive motor 11 is preferably a servo motor. The output end of the first drive motor 11 is connected to a first lead screw 12, and a first thread rolling bearing 13 is mounted on the first lead screw 12. Two first slide rails 14 are mounted parallel to each other on the base plate 10 on both sides of the first lead screw 12. A first slider 15 is mounted on each of the first slide rails 14. A base 16 is connected to the two first sliders 15. The first thread rolling bearing 13 is fixedly mounted on the bottom of the base 16. A support plate 17 is vertically mounted on the base 16. The Z-axis linear module 2 is mounted on the support plate 17. Thus, the first drive motor 11 drives the first lead screw 12 to rotate, thereby driving the base 16 and the support plate 17 to move left and right, and thus driving the Z-axis linear module 2 to move left and right. The drive mechanism of the servo motor and the lead screw enables the Z-axis linear module 2 to reciprocate more accurately in the X-axis direction.

[0040] Furthermore, such as Figure 4 and Figure 5 As shown, a second slide rail 24 is longitudinally arranged on the support plate 17, and a matching second slider 25 is provided on the second slide rail 24. An upper bracket 27 and a lower bracket 28 are respectively installed on the support plate 17 at the upper and lower ends of the second slide rail 24; the Z-axis linear module 2 includes a second drive motor 20 installed on the upper bracket 27 and a coupling 21 and a second lead screw 22 connected in sequence to the output end of the second drive motor 20, and the second lead screw 22 is rotatably connected between the upper bracket 27 and the lower bracket 28; The second lead screw 22 is equipped with a second thread rolling bearing 23, and the second slider 25 is equipped with a drive seat 26. The second thread rolling bearing 23 is fixed to the drive seat 26. In the above structure, the Z-axis linear module 2 is stably fixed on the support plate 17 by the arrangement of the upper bracket 27 and the lower bracket 28. In this embodiment, five sets of Z-axis linear modules 2 are arranged in parallel. The X-axis linear module 1 and the Z-axis linear module 2 enable the multiple workpieces adsorbed by the suction nozzle 32 to be accurately transferred at multiple workstations.

[0041] Specifically, the support plate 17 is equipped with a first limit sensor 171 and a second limit sensor 172 on one side of the second slide rail 24, and a limit sensing plate 261 is installed on one side of the drive seat 26. This structure enables the second drive motor 20 to precisely drive the suction nozzle 32 to move up and down to its maximum stroke, ensuring that the suction nozzle 32 is not damaged when picking up or placing workpieces. The lower bracket 28 is equipped with an adjustable limit post 281 below the drive seat 26. By adjusting the height of the limit post 281, the maximum downward stroke of the suction nozzle 32 can be physically prevented, further improving the stability of the multi-station synchronous feeding mechanism.

[0042] In this embodiment, as Figure 6 As shown, the upper end of the "L"-shaped connecting plate 3 is fixed to the drive seat 26. A retaining plate 301 is provided on the "L"-shaped connecting plate 3, and the vacuum generator 30 is secured within the retaining plate 301. Below the retaining plate 301, the "L"-shaped connecting plate 3 has a "T"-shaped bracket 302. A rotary connector 303 is mounted on the "T"-shaped bracket 302, with both ends of the rotary connector 303 connected to the hollow shafts of the vacuum generator 30 and the hollow rotary motor 31, respectively. Below the "T"-shaped bracket 302, the "L"-shaped connecting plate 3 has a third limit sensor 310. The hollow rotary motor 31... The hollow shaft is equipped with a limit sensing ring 311 that matches the third limit sensor 310. The hollow rotary motor 31 is preferably a hollow stepper motor. When the hollow stepper motor drives the hollow shaft to rotate, under the restriction of the third sensor and the limit sensing ring 311, the rotation angle of the workpiece adsorbed by the suction nozzle 32 can be precisely controlled. As a result, the workpiece can be placed at any angle, which solves the problem that the traditional feeding mechanism cannot change the angle of the workpiece when it is placed. At the same time, the structure of this multi-station synchronous feeding mechanism is simple and its manufacturing cost is low, which reduces the purchase cost of the equipment.

[0043] Specifically, such as Figure 4 As shown, a connector 161 and a pressure gauge 162 are mounted on the top of the base 16. The connector 161 is connected to the pressure gauge 162 and the vacuum generator 30 respectively. The pressure gauge 162 can be used to observe the suction force of the suction nozzle 32 on the workpiece in real time, so as to ensure that the workpiece can be stably suctioned by the suction nozzle 32 or to prevent the suction nozzle 32 from generating excessive negative pressure and damaging the workpiece.

[0044] 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.
