DETAILED DESCRIPTION
[0010] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.
[0011] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.
[0012] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.
[0013] This solution provides a special device for transferring a screen frame. The special device for transferring a screen frame adopts a clamping method rather than a suction cup method to transfer the screen frame, and has the advantage of occupying a small area.
[0014] Specifically, Figure 1 and Figure 2 As shown, the special device for transferring the screen frame provided by this solution includes:
[0015] A displacement transfer driving member 10 for realizing three-axis displacement drive, and a clamping jaw assembly 20 connected to the displacement transfer driving member 10, wherein the clamping jaw assembly 20 includes a clamping jaw main frame 21 and a clamping jaw structure 22 arranged on the clamping jaw main frame 21, wherein the clamping jaw structure 22 includes an upper clamping jaw 221 and a lower clamping jaw 222 arranged in back to back and driven by a motor, the upper clamping jaw 221 is located above the clamping jaw main frame 21, and the lower clamping jaw 222 is located below the clamping jaw main frame 21.
[0016] Specifically, the displacement transfer driving member 10 includes a driving base 11, a Z-axis displacement member 12 that changes its stroke along the Z-axis direction relative to the driving base 11, a lateral displacement member 14 connected to the Z-axis displacement member 12 through a rotating shaft 13, and a translation member 15 slidably arranged on the lateral displacement member 14. The clamping jaw assembly 20 is located on the translation member 15. Specifically, the Z-axis position member 412 is driven to change its displacement relative to the driving base 11 to achieve the displacement of the special device for screen frame transfer in the Z-axis direction, the lateral displacement member 14 is driven to rotate by the driving shaft 13 to achieve the position change of the special device for screen frame transfer between the hot press 20 and the molding machine 10, and the translation member 15 is driven to translate relative to the lateral displacement member 14 to achieve the translation of the special device for screen frame transfer in the horizontal direction.
[0017] This solution realizes the structural simplification of the special device for screen frame transfer through the displacement transfer driving member 10 with three-axis displacement changes. Specifically, a Z-axis sliding track is provided on the side of the driving base 11, and the Z-axis displacement member 12 is slidably set on the Z-axis sliding track by a motor drive to achieve displacement in the Z-axis direction. The top of the Z-axis displacement member 12 is connected to the lateral displacement member 14 through a rotating shaft 13 driven by a motor. In a preferred embodiment, the rotating shaft 13 is connected to the middle position of the lateral displacement member 14 to further reduce the footprint of the screen frame transfer robot. A lateral displacement track is set on the lateral displacement member 14, and the translation member 15 is movably connected to the lateral displacement track of the lateral displacement member 14 through a driving belt to cause displacement changes along the setting direction of the lateral displacement track.
[0018] like Figure 2 As shown, in the embodiment of the present scheme, the upper clamp 221 is composed of a first upper clamp and a second upper clamp that are arranged relatively, and when the first upper clamp and the second upper clamp are close to each other, the upper clamp 221 is in a clamping state, and when the first upper clamp and the second upper clamp are relatively far away from each other, the upper clamp 221 is in a non-clamping state. Similarly, the lower clamp 222 is composed of a first lower clamp and a second lower clamp that are arranged relatively, and when the first lower clamp and the second lower clamp are close to each other, the lower clamp 222 is in a clamping state, and when the first lower clamp and the second lower clamp are relatively far away from each other, the lower clamp 222 is in a non-clamping state.
[0019] In addition, in some embodiments, the clamp structure 22 additionally includes a fixed support 223 located between the upper clamp 221, and the first upper clamp and the second upper clamp are designed as L-shaped bars. When the upper clamp 221 is in a clamping state, the empty net frame is positioned on the fixed support 223 and the first upper clamp and the second upper clamp are against both sides of the empty net frame to cooperate to achieve the clamping of the empty net frame. The advantage of such a design is that the structure of the net frame will not be damaged. In some embodiments, the first lower clamp and the second lower clamp are also designed as L-shaped bar structures. When the lower clamp 222 is in a clamping state, the first lower clamp and the second lower clamp cooperate to form a space for placing the wet embryo net frame. In other words, at this time, the bottom of the wet embryo net frame is supported by the first lower clamp and the second lower clamp to achieve the clamping and fixing effect.
[0020] In addition, in some embodiments, the upper clamping jaw 221 and the lower clamping jaw 222 on the clamping jaw structure 22 are located on the upper and lower sides of the middle piece and are independently controlled by motors. The advantage of such a design is that the volume size of the screen frame transfer robot 40 can be further reduced.
[0021] Specifically, in an embodiment of the present scheme, the upper clamp 221 of the special device for driving the screen frame transfer obtains the screen frame containing the plant fiber product from the hot press, and the empty screen frame is obtained by transferring the plant fiber product on the screen frame through the material preparation mechanical tooling, and then the special device for screen frame transfer is driven to transfer the empty screen frame to the forming machine; then the special device for screen frame transfer moves downward to drive the lower clamp 222 to be converted into a clamping state to clamp the wet embryo screen frame and then exit, and then the special device for screen frame transfer is driven to transfer the wet embryo screen frame to the hot press for hot pressing treatment.
[0022] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
