Description

Technical Field

[0001] This invention relates to the field of intelligent profile processing technology, and in particular to an intelligent tool lifting method for aluminum profile processing. Background Technology

[0002] Currently, tool lifting during milling is a neglected issue. Intelligent tool lifting can reduce machining time, especially when machining multiple patterns on a single material, thereby reducing production costs and increasing company profits.

[0003] Chinese patent CN107643727A discloses an intelligent blade lifting system for a shearing machine based on machine vision and its implementation method. This device can automatically lift the brush blade and shearing blade through the control system using vision methods to enable the fabric sewing action. It has a simple structure, high control precision, low failure rate, saves labor, increases efficiency, and improves product quality.

[0004] The existing tool lifting functions on the market are divided into two categories. Some rely on user-input parameters to fix the lifting height each time. If the user sets the height too high, it will lead to longer processing time and lower processing efficiency. If the height is set too low, it will pose a safety hazard. Other methods use a vision system to determine the lifting height and lift the tool intelligently. This method increases production costs and is not suitable for some machines that do not have vision functions.

[0005] Therefore, a new solution is urgently needed to address the aforementioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to overcome the problems of the prior art and provide an intelligent tool lifting method for aluminum profile processing, so as to solve the technical problems of improper parameter settings affecting processing efficiency and causing safety hazards in the prior art.

[0007] The above objectives are achieved through the following technical solutions:

[0008] A smart tool lifting method for aluminum profile processing includes an aluminum profile processing mechanism and a controller. The aluminum profile processing mechanism receives processing instructions from the controller and performs aluminum profile processing according to the processing instructions. The aluminum profile processing mechanism includes a resolution sensor module, a processing sensor module, and a cutting tool. The method is as follows:

[0009] The controller receives the processing parameters and graphic data input by the user and generates the processing instructions;

[0010] The analytical sensor module receives the machining command, analyzes and generates the machining trajectory, formulates the tool lifting rules, and creates new machining commands;

[0011] The machining sensor module receives and parses the new machining command, and controls the tool machining and tool lifting.

[0012] Furthermore, the processing parameters include profile information, user-desired safe height, tool magazine position, fixture height, and Z-offset information.

[0013] Furthermore, the cutting tools include a milling cutter and a drilling cutter; the milling cutter is used to cut the profile, and the drilling cutter is used to drill holes in the profile.

[0014] Furthermore, the knife-lifting rules include:

[0015] (1) Tool number determination

[0016] If the tool numbers are inconsistent, the tool needs to be changed. The tool lifting height is equal to the tool magazine changing height.

[0017] (2) Determining the face number

[0018] If the tool numbers are the same, then check if the surface numbers are the same.

[0019] If the dough numbers do not match, it needs to be flipped over. The specific height to lift the knife is as follows:

[0020] Top surface tool lifting height = user-expected safe height + top surface Z-direction offset + the larger of material height and top surface fixture height + current tool length;

[0021] Front safety height = User-expected safety height + Front Z-offset + Material width + Front fixture height + Current tool length;

[0022] Rear safety height = User-expected safety height + Rear Z-offset + Material width + Rear fixture height + Current tool length;

[0023] (3) Whether it is necessary to pass through the fixture midway.

[0024] If the surface numbers are consistent, determine whether it is necessary to pass through a fixture in the middle;

[0025] If the blade needs to pass through a clamp midway, the specific lifting height is as follows:

[0026] Top surface safety height = User-expected safety height + Top surface Z-offset + The larger of material height and top surface fixture height + Current tool length;

[0027] Front safety height = User-expected safety height + Front Z-offset + Material width + Front fixture height + Current tool length;

[0028] Rear safety height = User-expected safety height + Rear Z offset + Material width + Rear fixture height + Current tool length;

[0029] If the tool does not need to pass through the clamp midway, the specific lifting height is as follows:

[0030] Top surface safety height = User-expected safety height + Top surface Z-offset + Material height + Current tool length;

[0031] Front safety height = User-expected safety height + Front Z-offset + Material width + Current tool length;

[0032] Rear safety height = User-expected safety height + Rear Z offset + Material width + Current tool length.

[0033] Furthermore, in the determination of the surface number in (2), the higher of the current surface being processed and the surface to be processed next is taken as the safe height.

[0034] Furthermore, if the surface being processed now and the surface to be processed next are the same surface, then the corresponding surface is taken as the safety height.

[0035] Beneficial effects

[0036] This invention provides an intelligent tool lifting method for aluminum profile machining. Based on user-input parameters such as fixture height, material width, material height, safety distance, workpiece Z-offset, tool change height, fixture height, the face of the next machining pattern, the tool number of the next machining pattern, and the position of the next machining pattern, the method automatically calculates the required tool lifting height and performs the lifting. The principle of height calculation in this method is to keep the tool as low as possible while ensuring safety, effectively improving machining efficiency and company profits. This method guarantees safety; the safe height calculated by the software is accurate and will not result in tool collisions or excessively low safe heights. It also improves machining efficiency because the software calculates the safe height as low as possible while ensuring safety, thus shortening the tool lifting time and the machining time for a single workpiece, thereby increasing machining efficiency.

[0038] Figure 2 This is a logic diagram of the lifting rules in the intelligent lifting method for aluminum profile processing described in this invention. Detailed Implementation

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. The described embodiments are merely some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] like Figure 1 As shown, an intelligent tool lifting method for aluminum profile processing includes an aluminum profile processing mechanism and a controller. The aluminum profile processing mechanism receives processing instructions from the controller and performs aluminum profile processing according to the processing instructions. The aluminum profile processing mechanism includes a resolution sensor module, a processing sensor module, and a cutting tool. The method is as follows:

[0041] The controller receives the processing parameters and graphic data input by the user and generates the processing instructions;

[0042] The analytical sensor module receives the machining command, analyzes and generates the machining trajectory, formulates the tool lifting rules, and creates new machining commands;

[0043] The machining sensor module receives and parses the new machining command, and controls the tool machining and tool lifting.

[0044] The machining parameters include profile information, user-desired safe height, tool magazine position, fixture height and Z-offset information, tool number of the next machining pattern, and position of the next machining pattern.

[0045] Specifically, the aluminum profile processing mechanism in this solution includes:

[0046] The analytical sensor module is used to analyze the graphic data on the processing mechanism and perform trajectory planning based on the actual input parameters and strategies.

[0047] The processing sensor module is used to send the cutting position information parsed by the parsing sensor;

[0048] The cutting tools include milling cutters and drilling cutters; specifically, the milling cutter is used to cut profiles, and the drilling cutter is used to drill holes in the profiles.

[0049] This plan includes the following steps:

[0050] Step 1: The user sets the parameters and graphic data on the controller according to the actual situation, loads the material, and clicks the start button to start automatic processing.

[0051] Step 2: The sensor module analyzes the output parameters and graphic data, performs trajectory planning, and plans the intelligent tool lifting, which is then sent to the machining sensor module.

[0052] Step 3: The machining sensor module controls the tool to intelligently lift the tool during machining based on the data from the analytical sensor module.

[0053] Step 4: Use milling cutters and drilling tools to cut the aluminum profile.

[0054] The parameters mainly include: profile information, user-desired safety height, tool magazine position, fixture information, offset information, etc.

[0055] like Figure 2 As shown, the core of this solution, the knife-lifting rules include:

[0056] (1) Tool number determination

[0057] If the tool numbers are inconsistent, the tool needs to be changed. The tool lifting height is equal to the tool magazine changing height.

[0058] (2) Determining the face number

[0059] If the tool numbers are the same, then check if the surface numbers are the same.

[0060] If the dough numbers do not match, it needs to be flipped over. The specific height to lift the knife is as follows:

[0061] Top surface tool lifting height = user-expected safe height + top surface Z-direction offset + the larger of material height and top surface fixture height + current tool length;

[0062] Front safety height = User-expected safety height + Front Z-offset + Material width + Front fixture height + Current tool length;

[0063] Rear safety height = User-expected safety height + Rear Z-offset + Material width + Rear fixture height + Current tool length;

[0064] Based on the safe height of the currently processed surface and the surface to be processed next, take the higher one as the safe height;

[0065] If the surface being processed now and the surface to be processed next are the same surface, then the corresponding surface is taken as the safety height.

[0066] (3) Whether it is necessary to pass through the fixture midway.

[0067] If the surface numbers are consistent, determine whether it is necessary to pass through a fixture in the middle;

[0068] If the blade needs to pass through a clamp midway, the specific lifting height is as follows:

[0069] Top surface safety height = User-expected safety height + Top surface Z-offset + The larger of material height and top surface fixture height + Current tool length;

[0070] Front safety height = User-expected safety height + Front Z-offset + Material width + Front fixture height + Current tool length;

[0071] Rear safety height = User-expected safety height + Rear Z offset + Material width + Rear fixture height + Current tool length;

[0072] If the tool does not need to pass through the clamp midway, the specific lifting height is as follows:

[0073] Top surface safety height = User-expected safety height + Top surface Z-offset + Material height + Current tool length;

[0074] Front safety height = User-expected safety height + Front Z-offset + Material width + Current tool length;

[0075] Rear safety height = User-expected safety height + Rear Z offset + Material width + Current tool length.

[0076] Specifically, the knife-lifting rule is the intelligent knife-lifting safety height calculation method, including:

[0077] 1. When a tool change is required: tool lifting height = tool magazine tool changing height.

[0078] 2. When you don't need to change the blade but need to flip the food:

[0079] (1) Top surface lifting height = User's expected safe height + Top surface Z-direction offset + The larger of the material height and the top surface fixture height + Current tool length;

[0080] (2) Front safety height = User-expected safety height + Front Z offset + Material width + Front fixture height + Current tool length;

[0081] (3) Safety height behind = User-expected safety height + Z-offset behind + Material width + Height of fixture behind + Length of current tool;

[0082] Based on the method above, calculate the safety height of both the currently processed surface and the surface to be processed next, and take the higher of the two safety heights.

[0083] If the surface being processed now and the surface to be processed next are the same surface, then the safe height of the corresponding surface is taken.

[0084] 3. When it is not necessary to change the tool, flip the blade, or bypass the fixture:

[0085] (1) Top surface safety height = User expected safety height + Top surface Z offset + The larger of material height and top surface fixture height + Current tool length;

[0086] (2) Front safety height = User-expected safety height + Front Z offset + Material width + Front fixture height + Current tool length;

[0087] (3) Safety height behind = User-expected safety height + Z-offset behind + Material width + Height of fixture behind + Current tool length;

[0088] According to the formula above, the safe height is the same as the previous safe height.

[0089] 4. When it is not necessary to change the tool, flip the blade, or skip the fixture:

[0090] (1) Top surface safety height = User-expected safety height + Top surface Z-offset + Material height + Current tool length

[0091] (2) Front safety height = User-expected safety height + Front Z-offset + Material width + Current tool length

[0092] (3) Rear safety height = User-expected safety height + Rear Z offset + Material width + Current tool length

[0093] According to the formula above, the safe height is the same as the previous safe height.

[0094] As a specific embodiment of this solution, the following is an example:

[0095] 1. When the tool number is the same but the face number is different, the higher of the two face safety heights will be used.

[0096] For example: If the current face is 0 degrees and the next processing graphic is on a face at 90 degrees, then according to the calculation logic, the safe height of the 0-degree face is calculated to be 1000, and the safe height of the 90-degree face is 800. Therefore, the safe height at this time is 1000.

[0097] 2. When the tool numbers are inconsistent, the safe height is the tool change height.

[0098] For example: if the current tool number is 1, the tool number of the next machining pattern is 2, and the user inputs a tool change height of 1000, then according to the calculation logic, the safe height will be 1000.

[0099] 3. When the tool number and face number are the same, calculate different safety heights based on whether the current position passes through the fixture to the position of the next machining graphic.

[0100] For example, if the current position is (100, 100) and the next processing position is (500, 100), and the fixture positions are 600, 1000, 50, 1200, then it is determined that the machine will not pass through the fixture, and the safe height is calculated according to the calculation logic.

[0101] For example, if the current position is (100, 100) and the next processing position is (500, 100), and the fixture positions are 300, 600, 800, and 1200, then it is determined that the machine has passed the fixture, and the safe height is calculated according to the calculation logic.

[0102] The above description is merely illustrative of the embodiments of the present invention and is not intended to limit the present invention. For those skilled in the art, 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.
