DETAILED DESCRIPTION

[0038] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0039] In view of the problem that the current door frame angle cutting operation process has low automation degree, resulting in large work intensity of operators, high labor cost and low work efficiency, the present application provides a door frame angle sawing device.

[0040] The embodiments of the present application will be described below with reference to the accompanying drawings. Figures 1 to 5

[0041] According to the embodiments of the present application, a door frame angle sawing device is provided, as shown in Figures 1 to 5 The device comprises a robot 1, a transfer platform 2, a cutting platform 3 and a rack 6.

[0042] Specifically, the robot 1 is provided with a door frame pickup piece 101;The transfer platform 2 is located on one side of the robot 1, and the transfer platform 2 is provided with a door frame placement area;The cutting platform 3 is located on one side of the transfer platform 2, and the cutting platform 3 is provided with a pair of oppositely arranged clamping assemblies 4 and a pair of angle sawing machines 5, one pair of clamping assemblies 4 for clamping door frame 9;One pair of angle sawing machines 5 is arranged one by one with one pair of clamping assemblies 4 and located on one side of one pair of clamping assemblies 4, and the angle sawing machine 5 is used for cutting the door frame 9;The rack 6 crosses the transfer platform 2 and the cutting platform 3, and the rack 6 is provided with a door frame carrying mechanism 601, and the door frame carrying mechanism 601 is located above the transfer platform 2 and the cutting platform 3.

[0043] ​The robot 1 provided with the door frame pickup piece 101 enables the door frame angle sawing device to automatically pick up the door frame 9 without manual carrying, reduces the work intensity of the operator, and reduces the labor cost. Secondly, the transfer platform 2 is arranged on one side of the robot 1, and the door frame placing area is arranged 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, the pair of clamping assemblies 4 on the cutting platform 3 can stably clamp the door frame 9, and then cooperate with the pair of angle sawing machines 5, which can not only realize the simultaneous cutting of the two ends of the door frame 9, but also improve the cutting efficiency; at the same time, the accuracy of the cutting process can be guaranteed, and the cutting quality can be improved. Finally, the door frame carrying mechanism 601 above the transfer platform 2 and the cutting platform 3 can enable the door frame 9 that has not been sawed or the door frame 9 that has been sawed to smoothly transfer between the transfer platform 2 and the cutting platform 3, thereby ensuring the continuity of production and improving the production efficiency.

[0044] It should be noted that the robot 1 in the embodiment can be a multi-axis robot 1. For example, the robot 1 in the 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 poses in the picking state, thereby better adapting to complex and variable door frame angle sawing device installation environments and reducing the possibility of collision between the door frame 9 and the items in the installation environment.

[0045] In addition, the door frame pickup piece 101 arranged on the robot 1 in the embodiment can be a gripper or a vacuum sponge suction cup. 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 is in contact with the surface of the door frame 9, the suction cup will generate sufficient adsorption force to overcome the weight of the door frame 9. It can be seen that compared with the gripper, the vacuum sponge suction cup does not need to prepare multiple types of grippers in advance to adapt to the shape of the door frame 9, thereby effectively reducing the procurement cost in the early stage. 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 will not cause damage to the door frame 9. It can be understood that to avoid damage to the door frame 9 by the gripper, a rubber structure can be arranged on the gripper. In this way, not only can the damage to the door frame 9 by the gripper be avoided, but also the friction between the gripper and the door frame 9 can be increased, thereby reducing the possibility of the door frame 9 falling.

[0046] To further improve the automation degree of the door frame angle sawing device in the embodiment, a controller electrically connected with the robot 1, the door frame pickup piece 101, the door frame carrying mechanism 601, the clamping assembly 4, and the angle sawing machine 5 can be additionally configured, and then through the program set in advance, the above-mentioned devices can be continuously and smoothly cooperated under the control of the controller. In this way, the participation of manual work is reduced, and the production efficiency is improved.

[0047] The operation process of the door frame corner sawing device is as follows: the robot 1 picks up the door frame 9 without sawing corners by using the door frame picking element 101 and places the door frame 9 without sawing corners on the door frame placing area on the transfer platform 2, then the door frame carrying mechanism 601 carries the door frame 9 without sawing corners placed on the door frame placing area to the pair of clamping assemblies 4 on the cutting platform 3, after the clamping assemblies 4 stably clamp the door frame 9 without sawing corners, the corner sawing machine 5 performs the corner sawing operation on the door frame 9 without sawing corners, when the corner sawing machine 5 completes the corner sawing operation on the specified position of the door frame 9, the clamping assemblies 4 return to the initial state to release the fixing effect of the door frame 9 after sawing corners, then the door frame carrying mechanism 601 carries the door frame 9 after sawing corners back to the door frame placing area, finally the robot 1 picks up the door frame 9 after sawing corners by using the door frame picking element 101 and transfers the door frame 9 after sawing corners from the door frame placing area to the specified position, thus completing a complete operation process.

[0048] According to one embodiment of the utility model, as shown in Figure 1 and Figure 4 , the clamping assembly 4 and the corresponding corner sawing machine 5 are arranged on the cutting platform 3 through the sliding mechanism 7, the sliding mechanism 7 is in sliding fit connection with the cutting platform 3, and the sliding direction of the sliding mechanism 7 is consistent with the length direction of the cutting platform 3. The sliding connection of the sliding mechanism 7 and the cutting platform 3 enables the pair of clamping assemblies 4 to flexibly adjust the relative position of the two on the cutting platform 3 according to the specifications of the door frame 9, which not only improves the flexibility and adaptability of the door frame corner sawing device, but also enables the corner sawing machine 5 to be always located near the end of the door frame 9, thereby ensuring that the corner sawing machine 5 can always perform the corner sawing operation on the specified position of the door frame 9 and improving the yield of products.

[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 manually driven to slide relative to the cutting platform 3, or a driving mechanism can be used to drive the sliding mechanism 7 to slide relative to the cutting platform 3. It can be understood that, compared with manual driving, the use of a driving mechanism can reduce the labor intensity of the operator and reduce labor costs. Further, to realize the automation of the sliding of the sliding mechanism 7, the driving mechanism can be electrically connected with a controller.

[0051] According to one embodiment of the utility model, the cutting platform 3 is provided with a rack arranged along the length direction thereof, and the sliding mechanism 7 is provided with a gear in meshing fit with the rack. The meshing structure of the gear and the rack provides stable and precise guidance for the movement of the clamping assembly 4 and the corner sawing machine 5, compared with ordinary sliding connection, the movement process is more stable, the position control is more accurate, and the fine cutting demand can be better met.

[0052] Further, the gear in the embodiment is connected with the output shaft of the motor, so that the sliding mechanism 7 can realize automatic forward and backward operation under the driving of the motor. In this way, not only the labor cost can be saved, but also the accuracy of each position adjustment can be ensured.

[0053] Further, in order to improve the stability of the sliding mechanism 7 during sliding, guide rails can be arranged on both sides of the cutting platform 3 in the width direction, and sliding blocks that are in sliding cooperation with the guide rails are arranged on the sliding mechanism 7.

The first clamping mechanism 403 is arranged opposite to the placement table 402 and adapted to abut against the outer side wall of the door frame 9. The second clamping mechanism 404 is adapted to abut against the top of the door frame 9. The third clamping mechanism 405 is adapted to abut 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, and meet different cutting requirements. Along the width direction of the cutting platform 3, part of the placement table 402 can be arranged in the door frame 9 and abut against the opposite inner side wall, which can provide internal support. Then, in cooperation with the first clamping mechanism 403 arranged opposite to the placement table 402 and abutting against the outer side wall of the door frame 9, the door frame 9 can be stably clamped from the inside and outside, so as to avoid the shaking and displacement of the door frame 9 during cutting. Further, 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 from the length, width and height directions of the door frame 9. In this way, the cutting deviation caused by unstable clamping is reduced, the accuracy of the sawing operation is ensured, and the product qualification rate is improved.

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

[0056] According to one embodiment of the utility model, as shown in Figure 1 and Figure 4As shown, the first clamping mechanism comprises a first driving member 4031 and a first clamping plate 4032 connected with the first driving member 4031, the first driving member 4031 is arranged on the first mounting base 401 and is adapted to drive the first clamping plate 4032 to move close to or away from the door frame 9; the second clamping mechanism 404 comprises a second driving member 4041 and a second clamping plate 4043 connected with the second driving member 4041, the second driving member 4041 is arranged on the first mounting base 401 and is located on the side of the placement table 402 away from the first clamping mechanism 403, the driving end of the second driving member 4041 is rotatably connected with the second clamping plate 4043 through a rotating arm 4042 and is adapted to drive the second clamping plate 4043 to move close to or away from the top of the door frame 9; the third clamping mechanism 405 comprises a third driving member 4051 and a positioning abutment 4052 connected with the third driving member 4051, the third driving member 4051 is arranged on the first mounting base 401 and is located below the placement table 402, and the third driving member 4051 is adapted to drive the positioning abutment 4052 to move close to or 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 from three directions of length, width and height of the door frame 9, thereby ensuring the stability of clamping and avoiding processing defects caused by shaking of the door frame 9.

[0057] According to one embodiment of the utility model, as shown in Figure 1 and Figure 4 As shown, the sawing angle machine 5 is arranged on the sliding mechanism 7 through the second mounting base 8, the second mounting base 8 is provided with a sliding rail, the length direction of the sliding rail is consistent with the cutting direction of the sawing angle machine 5; the sawing angle machine 5 is provided with a sliding block in sliding cooperation with the sliding rail. The sawing angle machine 5 is slidably connected with the second mounting base 8, on the one hand, the sawing angle machine 5 can move stably along the extension direction of the sliding rail during cutting, ensuring the linearity of the cutting action and avoiding deviation of the cutting path, so that the sawing angle operation on the door frame 9 can be completed according to the preset angle, improving the cutting precision. On the other hand, when facing door frames 9 of different sizes and specifications, the sliding cooperation structure can make the position adjustment operation of the sawing angle machine 5 become easy and convenient, reduce the adjustment time and improve the production efficiency.

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

Since the door frame 9 processed by the door frame angle sawing device has a notch on one side wall thereof, the rotating rods 202 are rotationally connected with the fixed frame, the state of the subsequent door frame 9 on the door frame carrying mechanism 601 can be adjusted, that is, the notch side of the door frame 9 is always faced to the placing table 402, so that the time required for adjusting the position of the door frame 9 can be reduced, and the continuity of the operation process is ensured. Secondly, by arranging the vacuum suction cups 203 on the rotating rods 202, the door frame 9 can be stably fixed on the rotating rods 202, the vibration in the rotating process of the rotating rods 202 can be avoided to affect the position of the door frame 9, and the consistency of the positions of different door frames 9 on the door frame carrying mechanism 601 is ensured.

[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 with a turnover motor. Secondly, the rotating angle range of the rotating rod 202 relative to the bottom frame 201 can be adjusted according to the design requirement. For example, the rotating rod 202 can be rotated by 90 degrees under the driving of the turnover motor. Specifically, during the feeding, the vacuum suction cup 203 is located above the rotating rod 202, after the robot 1 places the door frame 9 on the vacuum suction cup 203, the rotating rod 202 is rotated by 90 degrees clockwise or counterclockwise under the driving of the turnover motor.
