Description

Technical Field

[0001] The invention relates to the technical field of door frame corner sawing, and in particular to a door frame corner sawing device. Background Art

[0002] In the process of preparing doors, it is usually necessary to produce multiple door frames first, and then weld and assemble the multiple door frames according to the design requirements. In order to ensure the aesthetics of the final finished door, the door frames usually need to be corner-cut before welding. However, when performing the corner-cutting operation of the door frame, it is generally necessary for the operator to first move the door frame to the location of the corner sawing machine, and then use the corner sawing machine to complete the corner sawing process. This not only increases the workload and labor costs of the operators, but also hinders the improvement of work efficiency. Summary of the invention

[0003] In view of this, the present invention provides a door frame corner sawing device to solve the problem that the current door frame corner cutting operation process has a low degree of automation, resulting in high workload for operators, high labor costs and low work efficiency.

[0004] The present invention provides a door frame angle sawing device, comprising:

[0005] A robot with a door frame picker;

[0006] A transfer platform, located on one side of the robot, and a door frame placement area is provided on the transfer platform;

[0007] A cutting platform is located on one side of the transfer platform. A pair of clamping assemblies and a pair of angle saws are arranged on the cutting platform. The pair of clamping assemblies are used to clamp the door frame. The pair of angle saws are arranged in a one-to-one correspondence with the pair of clamping assemblies and are located on one side of the pair of clamping assemblies. The angle saws are used to cut the door frame.

[0008] A frame is provided across the transfer platform and the cutting platform. A door frame transport mechanism is provided on the frame. The door frame transport mechanism is located above the transfer platform and the cutting platform.

[0009] Beneficial effects: The present invention is equipped with a robot provided with a door frame picking piece, so that the door frame corner sawing device can automatically pick up the door frame without manual handling, which reduces the work intensity of the operator and reduces the labor cost. Secondly, a transfer platform is set on one side of the robot, and a door frame placement area is set on the transfer platform, which provides convenience for the temporary storage and turnover of the door frame and makes the whole process more orderly. Furthermore, a pair of clamping assemblies on the cutting platform can firmly clamp the door frame, and then cooperate with a pair of corner sawing machines, which can not only realize the simultaneous cutting of both ends of the door frame and improve the cutting efficiency; At the same time, it can also ensure the accuracy of the cutting process and improve the cutting quality. Finally, by using the door frame handling mechanism above the transfer platform and the cutting platform, the door frame that has not been sawed or the door frame that has been sawed can be smoothly transferred between the transfer platform and the cutting platform, which ensures the continuity of production and improves production efficiency.

[0010] In an optional embodiment, the clamping assembly and the corresponding angle sawing machine are arranged on the cutting platform via a sliding mechanism, the sliding mechanism is slidably connected to the cutting platform, and the sliding direction of the sliding mechanism is consistent with the length direction of the cutting platform.

[0011] Beneficial effects: The sliding mechanism is slidably connected to the cutting platform, so that a pair of clamping components can flexibly adjust their relative positions on the cutting platform according to the specifications of the door frame. This not only improves the flexibility and adaptability of the door frame corner sawing device, but also enables the corner sawing machine to always be located near the end of the door frame, ensuring that the corner sawing machine can always perform corner sawing operations at the designated position of the door frame, thereby improving the product yield.

[0012] In an optional embodiment, the cutting platform is provided with a rack arranged along the length direction thereof, and the sliding mechanism is provided with a gear meshing with the rack.

[0013] Beneficial effect: The meshing structure of the gear and the rack provides a stable and precise guide for the movement of the clamping assembly and the angle saw. Compared with ordinary sliding connections, the movement process is smoother, the position control is more precise, and it can better meet the needs of fine cutting.

[0014] In an optional embodiment, the clamping assembly includes a first mounting seat and a placing table arranged on the first mounting seat, a first clamping mechanism, a second clamping mechanism and a third clamping mechanism; the first mounting seat is arranged on the sliding mechanism, and along the width direction of the cutting platform, at least a part of the placing table is suitable for being inserted into the door frame and suitable for abutting against the inner side wall of the door frame opposite thereto; the first clamping mechanism is arranged opposite to the placing table and is suitable for abutting against the outer side wall of the door frame; the second clamping mechanism is suitable for abutting against the top of the door frame; the third clamping mechanism is suitable for abutting against the end of the door frame.

[0015] Beneficial effect: The first mounting seat is arranged on the sliding mechanism, so that the clamping assembly can flexibly adjust the relative position with the cutting platform to meet different cutting requirements. Along the width direction of the cutting platform, part of the placement table can be inserted into the door frame and abut against the relative inner wall, which can provide support from the inside, and then cooperate with the first clamping mechanism that is arranged opposite to the placement table and abuts against the outer wall of the door frame, so as to firmly clamp the door frame in both directions inside and outside, and avoid shaking and displacement of the door frame during the cutting process. Furthermore, the second clamping mechanism abuts against the top of the door frame, and the third clamping mechanism abuts against the end of the door frame, so that the clamping assembly can limit the position of the door frame in three directions of length, width and height of the door frame. In this way, the cutting deviation caused by unstable clamping is reduced, the accuracy of the angle sawing operation is guaranteed, and the product qualification rate is improved.

[0016] In an optional embodiment, the first clamping structure includes a first driving member and a first clamping plate connected to the first driving member, the first driving member is disposed on the first mounting seat and is suitable for driving the first clamping plate to move closer to or away from the door frame;

[0017] The second clamping mechanism comprises a second driving member and a second clamping plate connected to the second driving member, the second driving member is arranged on the first mounting seat and is located on a side of the placement platform away from the first clamping mechanism, the driving end of the second driving member is rotatably connected to the second clamping plate through a rotating arm, and is suitable for driving the second clamping plate to approach or move away from the top of the door frame;

[0018] The third clamping mechanism includes a third driving member and a positioning backer connected to the third driving member. The third driving member is arranged on the first mounting seat and located below the placement table. The third driving member is suitable for driving the positioning backer to be close to or away from the end of the door frame.

[0019] Beneficial effect: The first clamping mechanism, the second clamping mechanism and the third clamping mechanism cooperate with each other, so that the clamping assembly can limit the position of the door frame in three directions of length, width and height, thereby ensuring the stability of the clamping and avoiding processing defects caused by shaking of the door frame.

[0020] In an optional embodiment, the angle sawing machine is arranged on the sliding mechanism through a second mounting seat, and the second mounting seat is provided with a slide rail, and the length direction of the slide rail is consistent with the cutting direction of the angle sawing machine; the angle sawing machine is provided with a slider that slides with the slide rail.

[0021] Beneficial effects: The angle sawing machine is slidably connected to the second mounting seat. On the one hand, the angle sawing machine can move smoothly along the extension direction of the slide rail during the cutting process, ensuring the linearity of the cutting action and avoiding deviations in the cutting path, so that the angle sawing operation of the door frame can be completed according to the preset angle, thereby improving the cutting accuracy. On the other hand, when facing door frames of different sizes and specifications, this sliding matching structure can make the position adjustment operation of the angle sawing machine easy and convenient, reduce adjustment time, and improve production efficiency.

[0023] Beneficial effect: Since the door frame processed by the door frame angle sawing device has a notch on one side wall thereof, the state of the subsequent door frame on the door frame transport mechanism can be adjusted by rotating the rotating rod and the fixed frame, that is, ensuring that the notch side of the door frame always faces the placement table, which can reduce the time required for debugging the door frame position and ensure the continuity of the operation process. Secondly, by arranging a vacuum suction cup on the rotating rod, the door frame can be stably fixed on the rotating rod, avoiding the vibration of the rotating rod during the rotation process from affecting the position of the door frame, and ensuring the consistency of the positions of different door frames on the door frame transport mechanism.

[0024] In an optional embodiment, the door frame placement area includes a door frame loading area and a door frame unloading area; the rotating rods are a pair, and the pair of rotating rods are spaced apart along the length direction of the bottom frame, wherein the vacuum suction cup on one of the rotating rods forms the door frame loading area, and the vacuum suction cup on the other rotating rod forms the door frame unloading area.

[0025] Beneficial effect: Dividing the door frame placement area into a door frame loading area and a door frame unloading area can separate the door frame loading process from the unloading process, avoid mutual interference between the loading and unloading processes, and ensure the stability and smoothness of the operation of the door frame angle sawing device.

[0026] In an optional embodiment, there are multiple vacuum suction cups, and the multiple vacuum suction cups are arranged at intervals along the length direction of the rotating rod.

[0027] Beneficial effect: By providing a plurality of vacuum suction cups, the number of contact points between the rotating rod and the door frame can be increased, thereby improving the stability of adsorption.

Compared with manual transportation, the use of the door frame transportation mechanism improves the transportation efficiency. Secondly, a pair of door frame transportation parts are set on the Y-axis robot arm, and the pair of door frame transportation parts correspond to the door frame loading area and the door frame unloading area respectively, which can realize the parallel processing of the loading process and the unloading process, avoiding the waiting time of traditional single-line transportation, making the entire operation process more closely connected and smooth, ensuring the continuity of production, and improving the overall working efficiency of the door frame sawing device.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0039] In view of the problem that the current door frame corner cutting operation process has a low degree of automation, resulting in high workload for operators, high labor costs and low work efficiency, the present invention provides a door frame corner sawing device.

[0040] Combine the following Figures 1 to 5 , describing an embodiment of the present invention.

[0041] According to an embodiment of the present invention, a door frame angle sawing device is provided. Figures 1 to 5 As shown, it includes: a robot 1, a transfer platform 2, a cutting platform 3 and a frame 6.

[0042] Specifically, the robot 1 is provided with a door frame picking piece 101; the transfer platform 2 is located on one side of the robot 1, and a door frame placement area is provided on the transfer platform 2; the cutting platform 3 is located on one side of the transfer platform 2, and a pair of relatively arranged clamping assemblies 4 and a pair of angle sawing machines 5 are provided on the cutting platform 3, and the pair of clamping assemblies 4 are used to clamp the door frame 9; the pair of angle sawing machines 5 are arranged in a one-to-one correspondence with the pair of clamping assemblies 4 and are located on one side of the pair of clamping assemblies 4, and the angle sawing machine 5 is used to cut the door frame 9; the frame 6 spans the transfer platform 2 and the cutting platform 3, and a door frame conveying mechanism 601 is provided on the frame 6, and the door frame conveying mechanism 601 is located above the transfer platform 2 and the cutting platform 3.

[0043] This embodiment is equipped with a robot 1 provided with a door frame picking member 101, so that the door frame angle sawing device can automatically pick up the door frame 9 without manual handling, which reduces the work intensity of the operator and reduces the labor cost. Secondly, a transfer platform 2 is set on one side of the robot 1, and a door frame placement area is set on the transfer platform 2, which provides convenience for the temporary storage and turnover of the door frame 9 and makes the whole process more orderly. Furthermore, a pair of clamping components 4 on the cutting platform 3 can firmly clamp the door frame 9, and then cooperate with a pair of angle sawing machines 5, which can not only realize the simultaneous cutting of both ends of the door frame 9 and improve the cutting efficiency; at the same time, it can also ensure the accuracy of the cutting process and improve the cutting quality. Finally, by using the door frame conveying mechanism 601 above the transfer platform 2 and the cutting platform 3, the door frame 9 that has not been sawed or the door frame 9 that has been sawed can be smoothly transferred between the transfer platform 2 and the cutting platform 3, which ensures the continuity of production and improves production efficiency.

[0044] It should be noted that the robot 1 in this embodiment may be a multi-axis robot 1. Exemplarily, the robot 1 in this embodiment is a four-axis industrial robot 1, a five-axis industrial robot 1, a six-axis industrial robot 1, or a seven-axis industrial robot 1. It can be understood that by selecting a multi-axis robot 1, the door frame 9 can have more postures in the picking state, so that it can be better adapted to the complex and changeable installation environment of the door frame angle sawing device, and reduce the possibility of collision between the door frame 9 and objects in the installation environment.

[0045] In addition, the door frame picking member 101 provided on the robot 1 in this embodiment can be a clamp or a vacuum sponge suction cup. Among them, the vacuum sponge suction cup uses the principle of negative pressure adsorption to pick up the door frame 9, so when the vacuum sponge suction cup fits the surface of the door frame 9, the suction cup will generate an adsorption force sufficient to overcome the gravity of the door frame 9 itself. It can be seen that compared with the clamp, the vacuum sponge suction cup does not need to prepare a variety of different types of clamps in advance to adapt to the shape of the door frame 9 like the clamp, thus effectively reducing the initial procurement cost. In addition, the vacuum sponge suction cup is provided with a sponge, so in the process of picking up the door frame 9, the vacuum sponge suction cup generally does not cause damage to the door frame 9. It is understandable that in order to prevent the clamp from causing damage to the door frame 9, a rubber structure can be provided on the clamp. In this way, not only can the clamp avoid causing damage to the door frame 9, but also the friction between the clamp and the door frame 9 can be increased, reducing the possibility of the door frame 9 falling.

[0046] In order to further improve the degree of automation of the door frame angle sawing device of this embodiment, a controller electrically connected to the robot 1, the door frame picking member 101, the door frame transport mechanism 601, the clamping assembly 4 and the angle sawing machine 5 can be additionally configured, and then through a pre-set program, the above-mentioned devices can cooperate with each other continuously and smoothly under the control of the controller. In this way, manual participation is reduced and production efficiency is improved.

[0047] The operation flow of the door frame corner sawing device of this embodiment is as follows: the robot 1 uses the door frame picking member 101 to pick up the un-cornered door frame 9, and places the un-cornered door frame 9 in the door frame placement area on the transfer platform 2, and then the door frame transporting mechanism 601 will transport the un-cornered door frame 9 placed in the door frame placement area to a pair of clamping components 4 on the cutting platform 3, and after the clamping components 4 firmly clamp the un-cornered door frame 9, the corner sawing machine 5 will perform the corner sawing operation on the un-cornered door frame 9. When the corner sawing machine 5 completes the corner sawing operation on the designated position of the door frame 9, the clamping component 4 will return to the initial state to release the fixing effect on the door frame 9 after the corner sawing, and then the door frame transporting mechanism 601 will move the door frame 9 after the corner sawing back to the door frame placement area, and finally the robot 1 uses the door frame picking member 101 to pick up the door frame 9 after the corner sawing, and transfer the door frame 9 after the corner sawing from the door frame placement area to the designated position, which is a complete operation flow.

[0048] According to one embodiment of the present invention, Figure 1 and Figure 4 As shown, the clamping assembly 4 and its corresponding angle sawing machine 5 are arranged on the cutting platform 3 through the sliding mechanism 7, and the sliding mechanism 7 is connected to the cutting platform 3 in a sliding manner, and the sliding direction of the sliding mechanism 7 is consistent with the length direction of the cutting platform 3. The sliding mechanism 7 is connected to the cutting platform 3 in a sliding manner, so that the relative positions of the pair of clamping assemblies 4 on the cutting platform 3 can be flexibly adjusted according to the specifications of the door frame 9, which can not only improve the flexibility and adaptability of the door frame angle sawing device, but also make the angle sawing machine 5 always located near the end of the door frame 9, ensuring that the angle sawing machine 5 can always perform angle sawing operations on the designated position of the door frame 9, thereby improving the yield rate of the product.

[0049] It should be noted that the length direction of the cutting platform 3 is consistent with the length direction of the door frame 9 .

[0050] If the relative position relationship between the sliding mechanism 7 and the cutting platform 3 is changed, the sliding mechanism 7 can be driven manually to slide relative to the cutting platform 3, or the sliding mechanism 7 can be driven by a driving mechanism to slide relative to the cutting platform 3. It can be understood that, compared with manual driving, driving by a driving mechanism can reduce the labor intensity of the operator and reduce labor costs. Further, in order to realize the automation of the sliding of the sliding mechanism 7, the driving mechanism can be electrically connected to the controller.

[0051] According to one embodiment of the present invention, a rack is provided on the cutting platform 3 along its length, and a gear meshing with the rack is provided on the sliding mechanism 7. The meshing structure of the gear and the rack provides a stable and precise guide for the movement of the clamping assembly 4 and the angle saw 5. Compared with ordinary sliding connections, the movement process is smoother, the position control is more precise, and the fine cutting requirements can be better met.

[0052] Furthermore, the gear in this embodiment is connected to the output shaft of the motor, so that the sliding mechanism 7 can realize automatic forward and backward operation under the drive of the motor, which can not only save labor costs, but also ensure the accuracy of each position adjustment.

[0053] Furthermore, in order to improve the stability of the sliding mechanism 7 during the sliding process, guide rails can be respectively arranged on both sides of the cutting platform 3 in the width direction, and a slider that slides with the guide rails can be arranged on the sliding mechanism 7.

[0054] According to one embodiment of the present invention, Figure 1 and Figure 4 As shown, the clamping assembly 4 includes a first mounting seat 401 and a placement platform 402, a first clamping mechanism 403, a second clamping mechanism 404 and a third clamping mechanism 405 arranged on the first mounting seat 401; the first mounting seat 401 is arranged on the sliding mechanism 7, and along the width direction of the cutting platform 3, at least part of the placement platform 402 is suitable for passing through the door frame 9 and is suitable for abutting against the inner side wall of the door frame 9 opposite thereto; the first clamping mechanism 403 is arranged opposite to the placement platform 402 and is suitable for abutting against the outer side wall of the door frame 9; the second clamping mechanism 404 is suitable for abutting against the top of the door frame 9; and the third clamping mechanism 405 is suitable for abutting against the end of the door frame 9. The first mounting seat 401 is arranged on the sliding mechanism 7, so that the clamping assembly 4 can flexibly adjust the relative position with the cutting platform 3 to meet different cutting requirements. Along the width direction of the cutting platform 3, part of the placement platform 402 can penetrate into the door frame 9 and abut against the inner wall, which can provide support from the inside. Then, in conjunction with the first clamping mechanism 403 arranged opposite to the placement platform 402 and abutting against the outer wall of the door frame 9, the door frame 9 can be firmly clamped in both directions inside and outside to prevent the door frame 9 from shaking and displacement during the cutting process. Furthermore, the second clamping mechanism 404 abuts against the top of the door frame 9, and the third clamping mechanism 405 abuts against the end of the door frame 9, so that the clamping assembly 4 can limit the position of the door frame 9 in three directions of length, width and height. In this way, the cutting deviation caused by unstable clamping is reduced, the accuracy of the angle sawing operation is guaranteed, and the product qualification rate is improved.

[0055] It should be noted that the door frame 9 processed by the door frame angle sawing device has a notch on one side wall thereof, so at least part of the structure of the placement platform 402 can pass through the notch into the door frame 9 and abut against the inner wall of the door frame 9.

[0056] According to one embodiment of the present invention, Figure 1 and Figure 4As shown, the first clamping structure includes a first driving member 4031 and a first clamping plate 4032 connected to the first driving member 4031, the first driving member 4031 is arranged on the first mounting seat 401 and is suitable for driving the first clamping plate 4032 to move closer to or away from the door frame 9; the second clamping mechanism 404 includes a second driving member 4041 and a second clamping plate 4043 connected to the second driving member 4041, the second driving member 4041 is arranged on the first mounting seat 401 and is located on the placement table 402 away from the first clamping mechanism 403. On one side, the driving end of the second driving member 4041 is rotatably connected to the second clamping plate 4043 through the rotating arm 4042, and is suitable for driving the second clamping plate 4043 to approach or move away from the top of the door frame 9; the third clamping mechanism 405 includes a third driving member 4051 and a positioning backer 4052 connected to the third driving member 4051, the third driving member 4051 is arranged on the first mounting seat 401 and is located below the placement table 402, and the third driving member 4051 is suitable for driving the positioning backer 4052 to approach or move away from the end of the door frame 9. The first clamping mechanism 403, the second clamping mechanism 404 and the third clamping mechanism 405 cooperate with each other, so that the clamping assembly 4 can limit the position of the door frame 9 in three directions of length, width and height of the door frame 9, thereby ensuring the stability of the clamping and avoiding processing defects caused by the shaking of the door frame 9.

[0057] According to one embodiment of the present invention, Figure 1 and Figure 4 As shown, the angle sawing machine 5 is arranged on the sliding mechanism 7 through the second mounting seat 8, and the second mounting seat 8 is provided with a slide rail, and the length direction of the slide rail is consistent with the cutting direction of the angle sawing machine 5; the angle sawing machine 5 is provided with a slider that slidably cooperates with the slide rail. The angle sawing machine 5 is slidably connected to the second mounting seat 8. On the one hand, it can make the angle sawing machine 5 move smoothly along the extension direction of the slide rail during the cutting process, ensure the linearity of the cutting action, and avoid deviations in the cutting path, so that the angle sawing operation of the door frame 9 can be completed according to the preset angle, and the cutting accuracy can be improved. On the other hand, when facing door frames 9 of different sizes and specifications, this sliding cooperation structure can make the position adjustment operation of the angle sawing machine 5 easy and convenient, reduce adjustment time, and improve production efficiency.

[0058] It is understandable that if the relative position relationship between the angle sawing machine 5 and the second mounting seat 8 is changed, the angle sawing machine 5 can be driven manually to slide relative to the second mounting seat 8, or a driving member can be used to drive the angle sawing machine 5 to slide relative to the second mounting seat 8. It is understandable that, compared with manual drive, driving by a driving mechanism can reduce the labor intensity of the operator and reduce labor costs. Exemplarily, the driving member can be but is not limited to a linear motor and a cylinder. Furthermore, in order to realize the automation of the sliding of the angle sawing machine 5, the driving mechanism can be electrically connected to the controller.

[0059] According to one embodiment of the present invention, Figure 1 and Figure 3 As shown, the transfer platform 2 includes a pair of relatively arranged bottom frames 201 and a rotating rod 202, the rotating rod 202 is rotatably connected to the pair of bottom frames 201, and a vacuum suction cup 203 is arranged on the rotating rod 202, and the vacuum suction cup 203 forms a door frame placement area. Since the door frame 9 processed by the door frame angle sawing device has a notch on one side wall thereof, the state of the subsequent door frame 9 on the door frame transport mechanism 601 can be adjusted by rotating the rotating rod 202 and the fixed frame, that is, ensuring that the notch side of the door frame 9 always faces the placement platform 402, so that the time required for debugging the position of the door frame 9 can be reduced, and the continuity of the operation process can be ensured. Secondly, by arranging the vacuum suction cup 203 on the rotating rod 202, the door frame 9 can be stably fixed on the rotating rod 202, avoiding the vibration of the rotating rod 202 during the rotation process from affecting the position of the door frame 9, and ensuring the consistency of the position of different door frames 9 on the door frame transport mechanism 601.

[0060] It should be noted that in order to improve the automation level of the door frame angle sawing device, the end of the rotating rod 202 can be connected to the flip motor. Secondly, the rotation angle range of the rotating rod 202 relative to the bottom frame 201 can be adjusted accordingly according to design requirements. For example, the rotating rod 202 can be rotated 90 degrees under the drive of the flip motor. Specifically, when loading, the vacuum suction cup 203 is located above the rotating rod 202. When the robot 1 places the door frame 9 on the vacuum suction cup 203, the rotating rod 202 is driven by the flip motor to rotate 90 degrees clockwise or counterclockwise.

[0061] According to one embodiment of the present invention, Figure 1 and Figure 3 As shown, the door frame placement area includes a door frame loading area 204 and a door frame unloading area 205; the rotating rods 202 are a pair, and the pair of rotating rods 202 are arranged at intervals along the length direction of the bottom frame 201, and the vacuum suction cup 203 on one rotating rod 202 forms the door frame loading area 204, and the vacuum suction cup 203 on the other rotating rod 202 forms the door frame unloading area 205. Dividing the door frame placement area into the door frame loading area 204 and the door frame unloading area 205 can separate the loading process and the unloading process of the door frame 9, avoid mutual interference between the loading and unloading processes, and ensure the stability and smoothness of the operation of the door frame angle sawing device.

[0062] According to one embodiment of the present invention, Figure 1 and Figure 3 As shown, there are multiple vacuum suction cups 203, and the multiple vacuum suction cups 203 are arranged at intervals along the length direction of the rotating rod 202. By arranging multiple vacuum suction cups 203, the present embodiment can increase the number of contact points between the rotating rod 202 and the door frame 9 and improve the stability of adsorption.

[0063] According to one embodiment of the present invention, Figure 1 and Figure 5 As shown, the door frame transport mechanism 601 includes an X-axis robotic arm 6011, a Y-axis robotic arm 6012 vertically arranged with respect to the X-axis robotic arm 6011, and a door frame transport member 6013 arranged on the Y-axis robotic arm 6012, wherein the X-axis robotic arm 6011 and the Y-axis robotic arm 6012 are vertically arranged with respect to the length direction of the door frame 9; the door frame transport members 6013 are a pair, wherein one of the door frame transport members 6013 corresponds to the door frame loading area 204, and the other door frame transport member 6013 corresponds to the door frame unloading area 205.

[0064] Whether it is to transport the un-cornered door frame 9 from the door frame loading area 204 to the cutting platform 3, or to transport the sawed door frame 9 from the cutting platform 3 to the door frame unloading area 205, the door frame 9 can be transported to the target position through the coordinated cooperation of the X-axis robot arm and the Y-axis robot arm. Compared with manual transportation, the use of the door frame transportation mechanism 601 improves the transportation efficiency. Secondly, a pair of door frame transportation parts 6013 are set on the Y-axis robot arm 6012, and the pair of door frame transportation parts 6013 correspond to the door frame loading area 204 and the door frame unloading area 205 respectively, which can realize the parallel processing of the loading process and the unloading process, avoid the waiting time of the traditional single-line transportation, make the whole operation process more closely connected and smooth, ensure the continuity of production, and improve the overall working efficiency of the door frame sawing device.

[0065] It should be noted that the door frame transporting member 6013 of this embodiment can be a clamping claw or a vacuum sponge suction cup.

[0066] The operation process of the door frame corner sawing device of this embodiment is as follows: the robot 1 places the first door frame 9 in the door frame loading area 204, the flip motor drives the rotating rod 202 to rotate 90 degrees, the door frame transport part 6013 moves downward on the Y-axis robot arm 6012 and picks up the first door frame 9 in the door frame loading area 204, and then the door frame transport part 6013 moves upward on the Y-axis robot arm 6012 to a safe height; when the door frame transport part 6013 is moved to the top of the cutting platform 3 through the X-axis robot arm 6011, the door frame transport part 6013 moves downward on the Y-axis robot arm 6012 and places the first door frame 9 on the clamping assembly 4, and then the corner sawing machine 5 moves in the direction of the first door frame 9 driven by the sliding mechanism 7 until it reaches the set position, and then the clamping assembly 4 clamps the first door frame 9, and the saw blade of the corner sawing machine 5 starts to rotate, and the corner sawing operation of the first door frame 9 begins.

[0067] During the sawing operation of the first door frame 9, the robot 1 will place the second door frame 9 on the door frame loading area 204, and the door frame transporting member 6013 corresponding to the door frame loading area 204 (hereinafter referred to as the "loading transporting member" for the convenience of expression) will walk to the door frame loading area 204 and grab the second door frame 9. After the loading transporting member ascends to a safe height, the door frame transporting member 6013 corresponding to the door frame unloading area 205 (hereinafter referred to as the "unloading transporting member" for the convenience of expression) will walk above the cutting platform 3. After the sawing operation of the first door frame 9 is completed, the clamp assembly is released, the unloading transporting member descends, grabs the first door frame 9 that has been sawed, and rises. The loading transporting member then walks above the cutting platform 3, and the loading transporting member descends to place the second door frame 9 on the clamping assembly 4, the sawing machine 5 moves into place, and the clamping assembly 4 clamps the second door frame 9 to perform the sawing operation of the second door frame 9.

[0068] While the loading and transporting part places the second door frame 9 on the clamping assembly 4, the robot 1 places the third door frame 9 on the door frame loading area 204. The unloading and transporting part moves to the top of the transfer platform 2, then moves downward to place the first door frame 9 on the door frame unloading area 205, and then the unloading and transporting part moves upward to a safe height. At the same time, the loading and transporting part moves downward to grab the third door frame 9, and then the loading and transporting part moves upward to a safe height. The unloading and transporting part moves to the top of the cutting platform 3, and after the sawing operation is completed, the unloading and transporting part moves downward to grab the second door frame 9 that has been sawed, and then moves upward. The loading and transporting part moves to the top of the cutting platform 3, and the loading and transporting part moves downward to place the third door frame 9 on the clamping assembly 4, the sawing machine 5 moves into place, and the clamping assembly 4 clamps the third door frame 9, and the sawing operation of the third door frame 9 is performed. At this time, the robot 1 puts the fourth door frame 9 on the door frame loading area 204, and then takes down the first door frame 9 which has been sawed from the door frame unloading area 205. The operation is repeated in this way.
