At the same time, due to its excellent weather resistance, it effectively extends the service life of the window frame.

[0004] It is essential to cut the profiles during the preparation of window frames. However, currently, the profile cutting process in the window frame processing process is mostly done by workers performing mechanical cutting, which not only affects the cutting accuracy but also poses a safety hazard. Summary of the invention

[0005] To this end, the present invention provides a low-carbon and environmentally friendly window frame sash and a method for making the same, so as to overcome the problem in the prior art that the profile cutting process in the window frame processing process is mostly done by workers performing mechanical cutting, which not only affects the cutting accuracy but also poses a safety hazard.

[0006] To achieve the above object, the present invention provides a low-carbon and environment-friendly window frame and sash manufacturing method, comprising:

[0007] Performing preliminary processing on the profiles to form first-type profiles and second-type profiles that meet length requirements;

[0008] Cut the two ends of the first type of profile and the second type of profile at the fitting surface by an automatic cutting device to produce a first type of spliced ​​profile and a second type of spliced ​​profile;

[0009] Selecting one of the first-type splicing profiles and clamping it with a clamping base, placing a second-type splicing profile on the bonding surfaces at both ends of the first-type splicing profile, and bonding the bonding surface of the second-type splicing profile to the bonding surface of the first-type splicing profile;

[0010] Connecting the second type of splicing profile with the first type of splicing profile by means of adhesive and auxiliary splicing sheets;

[0011] Another first-type splicing profile is selected and two bonding surfaces of the first-type splicing profile are connected to the remaining bonding surfaces of each of the second-type splicing profiles by means of adhesive and auxiliary splicing sheets;

[0012] When cutting the fitting surfaces of the first type of profile and the second type of profile, the image information of the profile to be cut is collected in real time by the image detection device, the control assembly analyzes the collected image information, controls the moving position of the profile to be cut on the profile conveying device, and determines the clamping point and cutting point when cutting the profile. For profiles of the same type with different lengths, the clamping point and cutting point are different when cutting.

[0013] Furthermore, the sum of the fitting surface angles of the first type of splicing profiles and the fitting surface angles of the second type of splicing profiles is 90°.

[0014] Furthermore, the auxiliary splicing pieces are respectively connected to different splicing profiles by means of screws.

[0015] Furthermore, the fitting surface angle range of the first type of splicing profiles is 30°-60°.

[0016] Furthermore, the two ends of the first type of profile and the second type of profile are cut into fitting surfaces by an automatic cutting device, including:

[0017] Placing the profile to be cut on a profile conveying device having a conveying wheel set capable of changing the direction of travel of the profile;

[0018] The image detection device obtains image information of the profile to be cut and a position image of the profile on the profile conveying device;

[0019] The control assembly analyzes the collected image information, determines the type of the profile to be cut according to the length value of the profile to be cut, and determines the conditions for the conveying wheel group to change the operating mode;

[0020] The conveying wheel group drives the profile to be cut to move horizontally, so that the profile to be cut falls into the range of the cutting table. The control assembly determines the clamping point of the profile to be cut according to the positional relationship between the profile to be cut and the cutting table, and determines the cutting point;

[0021] After the cutting is completed, the cutting table is turned over to make the profile return to the profile conveying device, and the profile that has been cut is conveyed to a designated position.

[0022] Further, the type of the profile to be cut is determined according to the length value of the profile to be cut, and the condition for changing the operation mode of the conveying wheel group is determined, including:

[0023] The control assembly analyzes the collected image information to obtain the length value of the profile to be cut;

[0024] Compare the acquired length value with the preset first type profile length value interval and second type profile length value interval to determine the type of the profile to be cut;

[0025] Determine the position of the translation area of ​​the profile to be cut;

[0026] The image detection device detects the image of the profile to be cut in real time, and the control assembly uses the top position of the profile to be cut as the first observation point. When the first observation point falls into the translation area, the conveying wheel group of the control assembly changes the operation mode.

[0027] Furthermore, when acquiring the translation area, a calculation compensation parameter of the translation area edge range is set, and the value of the translation area edge range is positively correlated with the calculation compensation parameter of the translation area edge range, and the value of the calculation compensation parameter of the translation area edge range is determined by the length value of the profile to be cut.

[0028] Furthermore, the control assembly determines the clamping point of the profile to be cut according to the positional relationship between the profile to be cut and the cutting table, including:

[0029] The first tightening part tightens the left side of the profile to be cut that falls onto the cutting table;

[0030] The control assembly determines the clamping position of the second clamping portion by analyzing the positional relationship between the profile to be cut and the cutting table and combining the length of the profile to be cut.

[0031] Furthermore, the control assembly determines the cutting point, including:

[0032] Determine the cutting entry point of the first cutting assembly according to the relationship between the length of the profile to be cut and the minimum value of the length value interval of each type of profile, or according to the length of the profile to be cut;

[0033] The cutting entry point of the second cutting component is determined according to the cutting entry point of the first cutting component.

[0034] The invention also provides a low-carbon and environment-friendly window frame sash, the profile of which is glass fiber reinforced polyurethane.

[0035] Compared with the prior art, the beneficial effect of the present invention is that the present application can realize automatic cutting of window frame profiles through automatic cutting equipment to make its fixing, cutting and transportation fully automated, which can effectively increase production speed, improve production accuracy, and improve safety during window frame profile cutting.

[0036] Furthermore, the length of the profiles is identified, and various processing profiles are automatically classified to increase the processing speed. At the same time, the profiles that are too long or too short are automatically identified to ensure that the processed profiles are not wasted and reduce the waste of labor, materials and resources. At the same time, for profiles of different lengths, the evaluation interval range ratio is set differently. For the longer categories, the corresponding interval ratio value is smaller. The range interval is set by using the interval ratio instead of a fixed value, and the interval ratio value is set in a targeted manner, which not only meets the cutting needs, but also makes the cut corners not too long, saving material costs.

[0037] Furthermore, when the profile to be cut is transported on the profile conveying device, the profile can be transported at any angle on the profile conveying device through the inclined and interactively arranged conveying wheel group. The accurate position of the profile can be obtained by real-time image monitoring of the top of the profile. At the same time, the monitoring interval range is set to make the program run more stable. The profile itself has a certain inertia. If it is transported on the profile conveying device beyond the range of the translation area of ​​the profile to be cut, there may be a transportation transition, which is not conducive to cutting. By setting the range of the translation area of ​​the profile to be cut and performing detection to control the operation mode of the conveying wheel group, the profile to be cut can accurately fall into the area where cutting is allowed, thereby ensuring the processing quality.

[0038] Furthermore, for profiles of different lengths, the range of the translation area of ​​the profile to be cut is different. The size of the range of the translation area of ​​the profile to be cut is set in relation to the length of the profile, making the setting more targeted and meeting the needs of cutting. At the same time, in the determination process, the corresponding calculation coefficient is set considering the length of the profile, which further enhances the targetedness of the calculation and prevents the phenomenon that longer profiles are difficult to cut during transportation transition, so that the profile to be cut can accurately fall into the area allowed for cutting, thereby ensuring the processing quality.

[0039] Furthermore, for shorter profiles, in order to ensure that the tail end of the profile can be cut, the profile itself is gripped symmetrically to prevent the tail end from being cut and leaving an insufficient length; for medium-length profiles, after the first clamping part completes the gripping, the length of the profile left by its head is relatively high. Therefore, the length center point of the cutting table is used as the symmetry center point of the first clamping part and the second clamping part to ensure the stability of the gripping of the profile and make it easier to cut; for longer profiles, after the first clamping part completes the gripping, the length of the profile left by its head is longer than that of the medium-length profile. If the length center point of the profile itself or the length center point of the cutting table is used as the symmetry center point of the first clamping part and the second clamping part at this time, the gripping positions on both sides of the profile are too long, which is not conducive to cutting. Therefore, for longer profiles, the gripping position of the second clamping part is set to a fixed value of the left distance from the right end point of the profile to be cut, so that it can meet the cutting requirements; different gripping positions are determined for profiles of different lengths to ensure gripping stability and improve cutting accuracy.

[0040] Furthermore, since the first tightening part is fixed, it is inconvenient to adjust the gripping position of the first section of the profile, resulting in an uncertain length of the profile retained by the head after the first tightening part completes the gripping, and in certain cases it may be too long. Therefore, the head of the profile is cut first, and the position of the second cutting component is adjusted according to the condition of the head after cutting to improve the cutting accuracy.

[0051] See also Figure 1 As shown, it is a schematic flow chart of the low-carbon and environment-friendly window frame and sash manufacturing method in the embodiment.

[0052] The present invention provides a low-carbon and environment-friendly window frame and sash manufacturing method, comprising:

[0053] Step S1, preliminarily processing the profile to form a first type of profile and a second type of profile that meet the length requirements;

[0054] Step S2, cutting the two ends of the first type of profile and the second type of profile at the fitting surface by an automatic cutting device to produce a first type of spliced ​​profile and a second type of spliced ​​profile;

[0055] Step S3, selecting one of the first-type splicing profiles and clamping it with a clamping base, placing one of the second-type splicing profiles on the bonding surfaces at both ends of the first-type splicing profile, and bonding the bonding surface of the second-type splicing profile to the bonding surface of the first-type splicing profile;

[0057] Step S5, selecting another first-type splicing profile and connecting two bonding surfaces of the first-type splicing profile to the remaining bonding surfaces of each of the second-type splicing profiles by means of adhesive and auxiliary splicing sheets;

[0058] Specifically, when cutting the fitting surfaces of the first type of profile and the second type of profile, the image information of the profile to be cut is collected in real time by the image detection device, the control assembly analyzes the collected image information, controls the moving position of the profile to be cut on the profile conveying device, and determines the clamping point and cutting point when cutting the profile. For profiles of the same type with different lengths, the clamping point and cutting point are different when cutting.

[0059] The present application can realize automatic cutting of window frame profiles through automatic cutting equipment to make its fixing, cutting and transportation fully automated, which can effectively increase production speed, improve production accuracy, and improve safety during the window frame profile cutting process.

[0060] Specifically, the sum of the fitting surface angles of the first type of splicing profiles and the fitting surface angles of the second type of splicing profiles is 90°.

[0061] Specifically, see Figure 3 As shown, Figure 3 is a schematic diagram of the structure of the automatic cutting device in the embodiment, the automatic cutting device for cutting the profile includes

[0062] The profile conveying device 1 is used to convey the profile to be cut, and is provided with a conveying wheel set capable of changing the direction of travel of the profile;

[0063] An image detection device (not shown in the figure), which is arranged on the top of the profile conveying device 1 and is used to obtain image information of the profile to be cut and a position image of the profile on the profile conveying device 1;

[0064] A cutting table 2, which is arranged on one side of the profile conveying device and is used to place the profile to be cut, and a turning assembly is arranged under the cutting table;

[0065] A tightening assembly, comprising a first tightening part 3 fixedly arranged on the cutting table and a second tightening part 4 capable of sliding on the cutting table, wherein the tightening position of the second tightening part 4 is determined by the tightening position of the first tightening part 3;

[0066] A cutting assembly, comprising a first cutting assembly 5 and a second cutting assembly 6, for cutting the two ends of the profile respectively;

[0067] The control assembly (not shown) is connected to the profile conveying device 1, the image detection device, the clamping component, and the cutting component respectively, and is used to control the working mode of each component.

[0068] See also Figure 2 As shown, Figure 2 Schematic diagram of a process of cutting the bonding surfaces of both ends of the first type of profile and the second type of profile by an automatic cutting device in an embodiment.

[0069] Specifically, the two ends of the first type of profile and the second type of profile are cut into fitting surfaces by an automatic cutting device, including:

[0070] Step S21, placing the profile to be cut on the profile conveying device 1 having a conveying wheel group capable of changing the moving direction of the profile;

[0071] Step S22, the image detection device obtains image information of the profile to be cut and a position image of the profile on the profile conveying device 1;

[0072] Step S23, the control assembly analyzes the collected image information, determines the type of the profile to be cut according to the length value of the profile to be cut, and determines the condition for the conveying wheel assembly to change the operating mode;

[0073] Step S24, the conveying wheel group drives the profile to be cut to move horizontally, so that the profile to be cut falls into the range of the cutting table 2, and the control assembly determines the clamping point of the profile to be cut according to the positional relationship between the profile to be cut and the cutting table 2, and determines the cutting point;

[0074] Step S25: After the cutting is completed, the cutting table 2 is turned over to make the profile return to the profile conveying device 1, and the profile that has been cut is conveyed to a designated position.

[0075] Specifically, the profile conveying device 1 transports the profiles to be cut;

[0076] The image detection device collects image information of the profile to be cut on the profile conveying device 1, and transmits the collected data to the control assembly, which analyzes the collected image information to obtain the length value L of the profile to be cut. The control assembly is provided with a minimum length value L1 of the first type of profile and a minimum length value L2 of the second type of profile, 0.8L1>L2;

[0077] If L1≤L≤1.1L1, the control assembly determines that the profile to be cut is a first type of profile;

[0078] If L2≤L≤1.2L2, the control assembly determines that the profile to be cut is a profile of the second type;

[0079] If the value of L is not within the range of [L1, 1.1L1] and [L2, 1.2L2], it is determined that the profile to be cut does not meet the cutting requirements. In this embodiment, L1=90CM, L2=50CM.

[0080] The length of the profiles can be identified, and various processing profiles can be automatically classified to increase the processing speed. At the same time, the profiles that are too long or too short can be automatically identified to ensure that the processed profiles are not wasted and reduce the waste of labor, materials and resources. At the same time, for profiles of different lengths, the evaluation interval range ratio is set differently. For the longer categories, the corresponding interval ratio value is smaller. The range interval is set by using the interval ratio instead of a fixed value, and the interval ratio value is set in a targeted manner, which can meet the cutting needs and make the cut corners not too long, saving material costs.

[0081] It should be noted that the embodiment of the present invention sets two types of profiles and profile interval ranges. In the actual production process, the number of profile interval ranges can be increased or decreased according to the needs of producing doors and windows.

[0082] Specifically, after determining the category of the profile to be cut, the image detection device detects the image of the profile to be cut in real time and transmits the collected data to the control assembly. The control assembly uses the top position of the profile to be cut as the first observation point A1. When the first observation point A1 falls into the translation area, the conveying wheel group of the control assembly changes the operation mode, drives the profile to be cut to move laterally, so that the profile to be cut falls into the range of the cutting table 2. The first clamping part 3 clamps the profile to be cut, and the image detection device collects the clamping position image of the first clamping part 3. The control assembly determines the clamping position of the second clamping part 4 by analyzing the positional relationship between the profile to be cut and the cutting table 2 and combining the length of the profile to be cut.

[0083] Specifically, the position setting of the translation area is different for profiles to be cut of different lengths. The length center point position B0 of the cutting table 2 is used as the reference point, and the range of the translation area is set to the distance range [S0, S1] to the left of the reference point, where S0=L / 2, S1=S0+L×a;

[0084] Wherein, a is the calculation compensation parameter of the edge range of the translation area, and the value of a decreases as the value of L increases.

[0085] The profiles are transported from left to right on the profile conveyor 1 .

[0086] When the profile to be cut is transported on the profile conveying device 1, the profile can be transported at any angle on the profile conveying device 1 through the inclined and interactively arranged conveying wheel group. The top of the profile is monitored in real time to obtain the accurate position of the profile. At the same time, the monitoring interval is set to make the program run more stable. The profile itself has a certain inertia. If it is transported on the profile conveying device 1 beyond the range of the translation area of ​​the profile to be cut, there may be a transportation transition, which is not conducive to cutting. By setting the range of the translation area of ​​the profile to be cut and performing detection to control the operation mode of the conveying wheel group, the profile to be cut can accurately fall into the area where cutting is allowed, thereby ensuring the processing quality.

[0087] In this embodiment, set

[0088] L≤55CM, a=0.1;

[0089] 55CM<L≤95CM, a=0.8;

[0090] L>95CM,a=0.5.

[0091] The first tightening part 3 is located at a distance H to the left of the length center point position B0 of the cutting table 2 , and the second tightening part 4 is located to the right of the length center point position B0 of the cutting table 2 .

[0092] For profiles of different lengths, the range of the translation area of ​​the profile to be cut is different. The size of the range of the translation area of ​​the profile to be cut is set in relation to the length of the profile, making the setting more targeted and meeting the needs of cutting. At the same time, in the determination process, the corresponding calculation coefficient is considered to set the length of the profile, which further enhances the targeted nature of the calculation and prevents the phenomenon that longer profiles are difficult to cut during transportation transition, so that the profile to be cut can accurately fall into the area allowed for cutting to ensure the processing quality.

[0093] In this embodiment, H is set to 18CM.

[0094] Specifically, the control assembly analyzes the clamping position image, obtains the length center position of the profile to be cut and records it as the second observation point A2, and analyzes the distance C0 between the second observation point A2 and the length center position B0 of the cutting table 2, and the distance M0 between the first clamping part 3 and the second observation point A2 of the profile to be cut.

[0095] If L≤3H, the tightening position of the second tightening part 4 is located at a distance M0 to the right of the second observation point A2;

[0096] If 3H<L≤4.5H, the clamping position of the second clamping part 4 is located at a distance H to the right of the length center point position B0 of the cutting table 2;

[0097] If L>4.5H, the clamping position of the second clamping portion 4 is located at a distance H to the left of the right end point of the profile to be cut.

[0098] For shorter profiles, in order to ensure that the tail end of the profile can be cut, the profile itself is grasped symmetrically to prevent the tail end from being cut and leaving insufficient length; for medium-length profiles, after the first tightening part 3 is grasped, the length of the profile left by its head is relatively high. Therefore, the length center point of the cutting table 2 is used as the symmetric center point of the first tightening part 3 and the second tightening part 4 to ensure the stability of the profile grasping and make it easier to cut; for longer profiles, after the first tightening part 3 is grasped, the length of the profile left by its head is relatively high. The length of the profile is longer than that of the medium length. If the center point of the length of the profile itself or the center point of the length of the cutting table 2 is used as the symmetrical center point of the first clamping part 3 and the second clamping part 4, the grasping positions on both sides of the profile are too long, which is not conducive to cutting. Therefore, for the profile with a longer length, the grasping position of the second clamping part 4 is set to a fixed value at a distance to the left of the right end point of the profile to be cut, so that it can meet the cutting requirements; different grasping positions are determined for profiles of different lengths to ensure the stability of grasping and improve the cutting accuracy.

[0099] After the second tightening part 4 completes tightening the profile to be cut, the first cutting component 5 first cuts the left end of the profile to be cut, and then the second cutting component 6 cuts the right end of the profile to be cut according to the cutting situation of the first cutting component 5.

[0100] The cutting entry point of the first cutting assembly 5 is at a distance M1 to the right of the left end point of the profile to be cut;

[0101] If (L-Li) / Li≤0.05, or L≤3H, then M1=(L-Li) / 2;

[0102] If (L-Li) / Li>0.05, and L>3H, then M1=L-Li-0.02Li;

[0103] After the first cutting assembly 5 completes cutting of the left end of the profile to be cut, the cutting entry point of the second cutting assembly 6 is determined, which is a distance Li to the right of the left end point of the profile to be cut;

[0104] i=1 or 2.

[0105] Since the first tightening part 3 is fixed, it is inconvenient to adjust the grabbing position of the first section of the profile, resulting in an uncertain length of the profile retained at the head after the first tightening part 3 completes the grabbing, and in certain cases it may be too long. Therefore, the head of the profile is cut first, and the position of the second cutting component 6 is adjusted according to the condition of the head after cutting to improve the cutting accuracy.

[0106] The invention also provides a low-carbon and environment-friendly window frame sash, the profile of which is glass fiber reinforced polyurethane. Figure 4 It is a structural schematic diagram of a low-carbon and environment-friendly window frame fan in an embodiment; Figure 5 The low-carbon and environment-friendly window frame and sash include two second-type spliced ​​profiles 102 and two first-type spliced ​​profiles 101.
