[0038] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical method of the present invention, but the present invention is not limited to these embodiments.

[0039] like Figure 1-4 As shown, the utility model provides a multi-position automatic sandpaper changing device, comprising:

[0040] Base 100;

[0041] A mobile module is provided on the base 100 and is provided with a rotatable quick-change head 200;

[0042] The positioning box 300, the planer box 400 and the sandpaper supply box 500 are all arranged on the base 100. There are at least two positioning boxes 300 and each of them is provided with a sanding head 600.

[0043] The rotatable quick-change head 200 is driven to move back and forth between the positioning box 300, the planer box 400, and the sandpaper supply box 500 by the mobile module.

[0044] The rotatable quick-change head 200 completes the action of grabbing and placing the sanding head 600 at the location of the positioning box 300, completes the action of removing the old sandpaper at the location of the planer box 400, and completes the action of obtaining new sandpaper at the location of the sandpaper supply box 500.

[0045] The automatic sandpaper changing device provided in this embodiment has at least the following advantages:

[0046] 1. Improved production efficiency: By providing at least two grinding heads 600 and using a rotatable quick-change head 200, the robot can quickly replace the grinding head 600 that has been pre-loaded with sandpaper without stopping, thereby greatly reducing the downtime caused by changing sandpaper and improving the overall efficiency of the grinding operation;

[0047] 2. Reduce manual intervention: The automated sandpaper changing process reduces the need for manual operation, which not only saves labor costs, but also avoids the consistency problems that may be caused by manual sandpaper replacement, thus ensuring the grinding quality;

[0048] 3. High degree of automation: The mobile module driven by the servo linear module enables the grinding head 600 to move precisely at different positions, ensuring the efficiency and accuracy of the entire sandpaper changing process.

[0049] Preferably, the mobile module includes:

[0050] The transverse moving module 110 is horizontally arranged on the base 100;

[0051] The longitudinal moving module 120 is vertically mounted on the transverse moving module 110 , and the rotatable quick-change head 200 is mounted on the longitudinal moving module 120 ;

[0052] The lateral moving module 110 is responsible for horizontal movement, while the longitudinal moving module 120 is responsible for vertical movement. Among them, the positioning box 300, the planer box 400, and the sandpaper supply box 500 are located on the same horizontal line, thereby achieving precise control of the position of the rotatable quick-change head 200, ensuring that it can accurately reach each preset operating position (such as the positioning box 300, the planer box 400 and the sandpaper supply box 500).

[0053] Preferably, the rotatable quick-change head 200 includes:

[0054] The rotary motor 210 is mounted on the longitudinal moving module 120 via a fixed plate;

[0055] A mounting bracket 220 connected to the turntable 211 of the rotary motor 210;

[0056] The connecting head 230 is provided on the mounting bracket 220 and is used for quick connection with the grinding head 600 . The mounting bracket 220 is driven to rotate by the rotary motor 210 , thereby driving the connecting head 230 and the grinding head 600 to rotate.

[0057] Specifically, when the grinding head 600 is placed in the positioning box 300, its air grinder 610 is set horizontally, and its joint part 620 for connecting with the connecting head 230 is set vertically upward. When the grinding head 600 moves to above the positioning box 300, the connecting head 230 on the mounting bracket 220 and the joint part 620 of the grinding head 600 are set correspondingly up and down. At this time, the mounting bracket 220 is driven downward by the longitudinal moving module 120, so that the connecting head 230 and the grinding head 600 can be quickly connected.

[0058] When the grinding head 600 is performing the action of stripping off the old sandpaper and acquiring the new sandpaper, the rotation of the rotatable quick connector drives the grinding head 600 to rotate until the air grinder 610 thereof is vertically downwardly arranged.

[0059] Preferably, a planer 410 is provided on the planer box 400. By moving the grinding head 600, the planer 410 will peel off the old sandpaper adhering to the grinding head 600. This design simplifies the removal process of the old sandpaper without the need for additional manual intervention or complex mechanical operation.

[0060] In addition, a sandpaper receiving box 420 is provided on the side of the planer box 400. After the grinding head 600 peels off the old sandpaper in the planer box 400, the old sandpaper automatically falls into the sandpaper receiving box 420, thereby collecting the old sandpaper and reducing subsequent cleaning work.

[0061] Preferably, new sandpaper is stacked in the sandpaper supply box 500 with the adhesive surface facing upward. When new sandpaper is needed, the air grinder 610 on the sanding head 600 applies downward pressure to contact and press the topmost piece of new sandpaper. This design allows new sandpaper to be easily and quickly bonded to the sanding head 600, achieving automatic acquisition of new sandpaper.

[0062] Through this mechanism, the grinding head 600 can automatically remove the old sandpaper and install the new sandpaper without human intervention, which greatly improves the efficiency of the sandpaper replacement process and reduces the workload of the operator.

[0063] Preferably, when the grinding head 600 has more than one air grinder 610 , the posture switching of the grinding head 600 is achieved by rotating the rotatable quick-change head 200 to complete the sandpaper replacement action of different air grinders 610 .

[0064] The technical means disclosed in the present invention are not limited to those disclosed in the above technical means, but also include technical solutions composed of any combination of the above technical features. The above is a specific embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.

[0065] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0066] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0067] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0068] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
