For example, they can refer to a fixed connection, a detachable connection, or an integral structure; 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, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] See Figures 1-2 This embodiment provides a multi-station parallel clamping mechanism, including a mounting plate 10. The mounting plate 10 is vertically arranged and extends laterally for a certain length to facilitate the arrangement of multiple clamping jaws. The mounting plate 10 is provided with two rows of fixing blocks 11, divided into an upper row and a lower row. Multiple fixing blocks are arranged at intervals in each row. Sliding grooves are opened on the fixing blocks 11. An upper linear guide 12 is arranged in the sliding groove of the upper row of fixing blocks, and a lower linear guide 13 is arranged in the sliding groove of the lower row of fixing blocks. Multiple upper clamping plates 14 are arranged at intervals on the upper linear guide 12, and multiple lower clamping plates 15 are arranged at intervals on the lower linear guide 13. The number of upper clamping plates 14 and lower clamping plates 15 is the same. The bottom ends of the upper clamping plates 14 and the lower clamping plates are at the same horizontal position. Two adjacent upper clamping plates 14 and lower clamping plates 15 together form a set of clamping jaws for clamping parts. The number of clamping jaws is determined according to actual needs. In this embodiment, 11 sets of clamping jaws are provided, which can clamp 11 parts at the same time.

[0021] In order to adjust the clamping range of each gripper, the mounting plate 10 is provided with a left-right rotating lead screw module 16. The upper linear rail 12 and the lower linear rail 13 are respectively connected to the two sliders of the left-right rotating lead screw module 16. The left-right rotating lead screw module 16 drives the upper linear rail 12 and the lower linear rail 13 to move relative to each other or in opposite directions, thereby driving the upper clamping plate 14 and the lower clamping plate 15 to move, so as to realize the synchronous adjustment of the clamping range of multiple grippers.

[0022] More specifically, the upper clamping plate 14 and the lower clamping plate 15 are respectively provided with clamping grooves 17. The shape of the clamping grooves 17 is determined according to the shape of the part to be clamped. The clamping grooves of the upper clamping plate 14 and the lower clamping plate 15, which form a set of clamps, are arranged opposite to each other.

[0023] In order to transfer the clamped parts to the next process, multiple lifting cylinders 18 are provided below the mounting plate 10. In this embodiment, three sets of lifting cylinders are provided, located at both ends and the middle position respectively. The output end of the lifting cylinder 18 is connected to the mounting plate to lift the entire mounting plate.

[0024] Preferably, three guide rods 19 are provided below the mounting plate 10. The mounting plate is connected to the guide rods 19 via linear bearings to achieve stable up and down movement of the mounting plate. At the same time, a mounting base 20 is provided below the mounting plate, and two sets of buffers 21 are provided on the mounting base 20. A limit plate 22 corresponding to the two sets of buffers is provided on the mounting plate 10 to buffer the rise and fall of the mounting plate.

[0025] In addition, after the mounting plate is raised, the product needs to be moved horizontally to the designated position. Therefore, a linear slide module 23 is set on the mounting plate 10, and a left and right rotary screw module 16 is connected to the slider of the linear slide module 23. Of course, the movement of the upper linear rail 12 and the lower linear rail 13 can also be driven independently. In this embodiment, considering factors such as cost and installation space, a set of left and right rotary screw modules 16 can be used to achieve synchronous movement of the upper linear rail 12 and the lower linear rail 13.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
