Those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0031] Aluminum substrates are required in the production process of circuit boards. During the circuit board manufacturing process, some aluminum substrates need to be laser cut to remove the unnecessary waste material to form the finished board material with a specified shape. For some aluminum substrates with internal laser-cut waste, the cutting gap between the finished board material and the waste is extremely narrow, making it impossible to use the conventional suction method to strip the waste from the finished board material. Therefore, production workers usually need to manually strip the waste from the finished board material using small-sized tools, resulting in low production efficiency.

[0032] Referring to Figures 1 to 3 , the waste cleaning tool for the board workpiece in the embodiment of the present invention includes a supporting plate 100 and a pressure plate 200. The supporting plate 100 is vertically provided with a plurality of waste passing holes 110, and the upper side of the supporting plate 100 forms a workpiece supporting surface; the pressure plate 200 is vertically movably arranged above the workpiece supporting surface, and the lower side of the pressure plate 200 is provided with waste pressing blocks 210 corresponding to the waste passing holes 110 one by one. The waste pressing blocks 210 are opposite to the waste passing holes 110, and a workpiece placing position is formed between the pressure plate 200 and the supporting plate 100.

[0033] When it is necessary to remove the waste of the board workpiece, place the board workpiece on the upper side of the supporting plate 100. At this time, the board workpiece is located below the pressure plate 200. Then, move the pressure plate 200 downward. The upper side of the supporting plate 100 supports and limits the finished board material. The pressing block can push the waste to strip it from the finished board material. Then, the waste leaves the finished board material through the waste passing holes 110 under the action of gravity, stripping all the waste on the finished board material at one time, thereby improving the production efficiency of stripping the waste from the finished board material.

[0034] After the waste of the board workpiece is removed, the finished board material can be taken out from the waste cleaning tool of the board workpiece.

[0035] Specifically, during mass production, the supporting plate 100 and the pressure plate 200 can be made corresponding to the position and shape of the laser-cut waste of the board workpiece. The cross-section of the waste pressing block 210 should be smaller than the cross-section of the waste of the board workpiece to facilitate the waste pressing block 210 to press the waste out of the board workpiece; the cross-section of the waste of the board workpiece should be smaller than the cross-section of the waste passing holes 110 to facilitate the waste to pass through the waste passing holes 110 under the action of gravity.

[0036] In an embodiment, a support member 300 is provided below the support plate 100. The support member 300 is used to support the support plate 100 and form a waste accommodating space 400 on the lower side of the support plate 100. The waste accommodating space 400 communicates with the waste through-hole 110. By providing the support member 300, when the waste cleaning tool is placed on the tabletop, the lower part of the support plate 100 is supported and suspended by the support member 300, and there is a waste accommodating space 400 between it and the tabletop. When the peeled waste falls through the waste through-hole 110, it can be temporarily stored at the waste accommodating space 400. When there is more waste to be temporarily stored, all the waste can be removed at one time, which is relatively convenient to use and does not require frequent waste cleaning.

[0037] In an embodiment, two or more support members 300 are provided below the support plate 100. The support members 300 are strip-shaped, and all the support members 300 are arranged in parallel at intervals. The support members 300 are staggered from the waste through-hole 110. By providing two or more support members 300, the support plate 100 can be supported relatively stably, and the layout mode between the support members 300 can form a waste accommodating space 400 between the support members 300, with a simple structure and easy implementation; the support members 300 are staggered from the waste through-hole 110, so as to facilitate the waste to pass through the waste through-hole 110 and fall to the waste accommodating space 400 under the action of gravity.

[0038] Specifically, there are at least two support members 300 below the support plate 100 to stably support the support plate 100. It can be imagined that the number of support members 300 below the support plate 100 can also be other numbers, such as three, four or more. Those skilled in the art can configure according to actual needs.

[0039] Specifically, in some other embodiments, the support member 300 can also be other shapes. For example, the support member 300 is a block, and the support plate 100 is supported by a plurality of support members 300 together.

[0040] In an embodiment, an elastic member 500 is provided between the support plate 100 and the pressure plate 200. When the pressure plate 200 moves downward, the elastic member 500 can apply an upward elastic force to the pressure plate 200. When the plate workpiece is placed into the waste cleaning tool, the plate workpiece is located below the pressure plate 200 and the elastic member 500. When the operator presses down the pressure plate 200 to descend, the elastic member 500 is elastically compressed, and the waste on the plate workpiece is removed. Subsequently, when the operator releases the pressure plate 200, the elastic member 500 elastically expands and pushes up the pressure plate 200, so that the pressure plate 200 can be more easily separated from the finished plate material, without the operator manually separating the pressure plate 200 from the finished plate material, which is simpler to use, reduces the labor intensity of the operator, and improves the production efficiency.

[0041] In an embodiment, the supporting plate 100 is provided with workpiece positioning posts 120 vertically, the pressure plate 200 is provided with guide holes 220 vertically, the workpiece positioning posts 120 penetrate through the guide holes 220, and the pressure plate 200 can move upward to disengage the guide holes 220 from the workpiece positioning posts 120. In order to facilitate the alignment of the waste material with the waste material ejection portion on the lower side of the pressure plate 200, the plate workpiece is provided with positioning holes. When using the waste material cleaning tool, first move the pressure plate 200 upward to separate it from the workpiece positioning posts 120 of the supporting plate 100, then align the positioning holes of the plate workpiece with the workpiece positioning posts 120, and place the plate workpiece on the supporting plate 100. At this time, the workpiece positioning posts 120 precisely position the plate workpiece. Subsequently, align the guide holes 220 of the pressure plate 200 with the workpiece positioning posts 120 again, and install the pressure plate 200 on the workpiece positioning posts 120 of the supporting plate 100. Move the pressure plate 200 downward to press out the waste material of the plate workpiece. Then, the pressure plate 200 can be removed from the workpiece positioning posts 120 to replace the plate workpiece, and continuous production can be carried out in sequence. The above structure can enable the waste material pressing block 210 to automatically align with the waste material on the plate workpiece, eliminating the need for production personnel to manually align it, with strong reliability, reducing production misoperations, and resulting in better production quality of the finished plate material. Moreover, the workpiece positioning posts 120 can not only guide the pressure plate 200 to keep the movement direction of the pressure plate 200 stable but also be used to position the workpiece, with strong functionality and a compact structure, without the need to separately set two different functional structures.

[0042] It can be imagined that guide holes 220 can also be provided on the supporting plate 100 and workpiece positioning posts 120 can be provided on the pressure plate 200, and those skilled in the art can specifically configure according to actual needs.

[0043] In an embodiment, the supporting plate 100 is provided with four workpiece positioning posts 120 vertically, and the pressure plate 200 is provided with guide holes 220 corresponding to the workpiece positioning posts 120 one by one. The setting of four workpiece positioning posts 120 and guide holes 220 makes the movement cooperation relationship between the pressure plate 200 and the supporting plate 100 relatively stable, improving the stability of the vertical movement trajectory of the pressure plate 200. It can be imagined that the supporting plate 100 can also be provided with two, three or more workpiece positioning posts 120 vertically, the corresponding pressure plate 200 is also provided with two, three or more guide holes 220, and the corresponding plate workpiece is also provided with two, three or more positioning holes.

[0044] In an embodiment, the supporting plate 100 is provided with two rows of workpiece positioning posts 120 in the left-right direction. Each row of workpiece positioning posts 120 includes two workpiece positioning posts 120 arranged in the front-back direction, and the distances between the two workpiece positioning posts 120 in the two rows are different. The above structure enables the plate workpiece and the pressure plate 200 to be sleeved on the workpiece positioning posts 120 only in a specified orientation, forming a physical anti-mistake measure, avoiding incorrect installation orientations of the plate workpiece and the pressure plate 200, and thus reducing the risks of waste cleaning and damage to the plate workpiece.

[0045] In an embodiment, an elastic member 500 is disposed between the supporting plate 100 and the pressure plate 200. When the pressure plate 200 moves downward, the elastic member 500 can apply an upward elastic force to the pressure plate 200; the elastic member 500 is a spring. Using a spring to provide the force for the upward movement and reset of the pressure plate 200 has a simple structure and is easy to implement. It can be imagined that the elastic member 500 can also be a structure with elasticity such as a rubber block or a silica gel block, or the elastic member 500 uses a spring sheet.

[0046] In an embodiment, an installation hole 230 is formed in the lower side of the pressure plate 200, and one end of the spring is embedded in the installation hole 230. By embedding one end of the spring through the installation hole 230, the installation of the spring is relatively firm.

[0047] In an embodiment, the installation hole 230 is coaxially arranged with the workpiece positioning post 120, and the spring is sleeved on the workpiece positioning post 120. With the above structure, the workpiece positioning post 120 is used to position the spring, so that the spring will not deflect during the compression process, which is beneficial to the smooth compression of the spring and convenient for use.
