[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 5 The embodiment of the present application provides a self-positioning tool, including: a machine 1; a plurality of first positioning mechanisms 2, which are arranged on the machine 1, and the plurality of first positioning mechanisms 2 enclose a positioning space for supporting a plate a, the first positioning mechanism 2 includes a fixed frame 21 fixedly connected to the machine 1 and a flip plate 22 rotatably connected to the fixed frame 21, the flip plate 22 includes a first part 221 and a second part 222 connected to the first part 221, the flip plate 22 includes a first state and a second state, when the flip plate 22 is in the first state, the first part 221 abuts against the four sides of the plate a, and the second part 222 abuts against the bottom of the plate a; and a second positioning mechanism 3, including a connecting plate 31 arranged on the flip plate 22 and a positioning assembly 32 arranged on the connecting plate 31, the positioning assembly 32 has a positioning hole 321 for positioning the welding part b.

[0035] In the present application, plate a is positioned by multiple first positioning mechanisms 2. When plate a is placed in the positioning space, the first parts 221 of the multiple flip plates 22 abut against the outer periphery of plate a, and the second parts 222 of the flip plates 22 abut against the bottom of plate a to support plate a, thereby completing the positioning of plate a. At this time, the second positioning mechanism 3 connected to the flip plate 22 positions the weldment b through the positioning hole 321, and can automatically complete the positioning of plate a and weldment b. The operation is simple and the work efficiency is improved.

[0036] Specifically, when the flip plate 22 is in the first state, the plate a is positioned, and the second positioning mechanism 3 is also in the positioning state. The second positioning mechanism 3 in this state can position the weldment b. The specific operation is to pass the weldment b through the positioning hole 321 of the positioning assembly 32, and the end of the weldment b is attached to the plate a, so that the positioning of the weldment b and the plate a is completed.

[0037] Specifically, the welded part b in the present application is a pipe fitting, and may also be other parts.

[0038] In some embodiments, when the flip plate 22 is in the first state, the first portion 221 is in a vertical direction, and the second portion 222 is in a horizontal direction.

[0039] In the present application, after the plate a is placed in the positioning space, it moves downward under the action of its own gravity, and the second part 222 of the flip plate 22 supports the plate a, and the first part 221 abuts against the outer side of the plate a to complete the positioning of the plate a. The plate a can be positioned by the gravity of the plate a by simply placing the plate a in the positioning space. When all the flip plates 22 are in the first state, it proves that the plate a is positioned. If one flip plate 22 is not in the first state, it proves that the plate a is not flat and is in a non-positioned state, and the plate a needs to be positioned again.

[0040] In some embodiments, the self-positioning tooling also includes a pressure sensor 4 arranged on the machine 1, and the detection end of the pressure sensor 4 is used to abut against the end of the first part 221 away from the plate a. When the flip plate 22 is in the first state, the pressure detected by the pressure sensor 4 reaches a first threshold; when the flip plate 22 is not in the first state, the pressure detected by the pressure sensor 4 is less than the first threshold.

[0041] In the present application, the plate a is placed in the positioning space, and as the plate a applies downward pressure to the second part 222 of the flip plate 22, the flip plate 22 is rotated to the first state. The first part 221 of the flip plate 22 positions the outer side of the plate a on one side, and abuts against the pressure sensor 4 on the other side. The pressure applied to the flip plate 22 can be detected by the pressure sensor 4. If the pressure detected by the pressure sensor 4 reaches the first threshold, it proves that the corresponding flip plate 22 is already in the first state; if the pressure sensor 4 does not detect the pressure or the detected pressure is less than the first threshold, it proves that the corresponding flip plate 22 has not rotated to the first state, and the plate a may be placed unevenly, because the plane area occupied by the plate a is the largest only when it is fully flat. Whether the plate a is fully positioned can be detected to improve the accuracy of positioning the plate a.

[0042] In some embodiments, it also includes a controller 5 and multiple adsorption mechanisms 6, the controller 5 is electrically connected to the pressure sensor 4 and the adsorption mechanisms 6, the multiple adsorption mechanisms 6 are arranged on the machine 1, and the adsorption mechanisms 6 are used to adsorb the four end corners of the bottom of the plate a; wherein, when the pressure sensor 4 detects that the pressure of the flip plate 22 is less than the first threshold value, the adsorption mechanism 6 corresponding to the above-mentioned flip plate 22 works to adsorb the corresponding end corners of the plate a.

[0043] In the present application, when the pressure sensor 4 is working, the detected pressure is converted into a signal and transmitted to the controller 5. The controller 5 makes a judgment based on whether the pressure value reaches the first threshold value. If the first threshold value is reached, it proves that the flip plate 22 is in the first state. If the first threshold value is not reached, it proves that the flip plate 22 is not in the first state. At this time, the controller 5 controls the corresponding adsorption mechanism 6 to work, and the adsorption mechanism 6 is used to adsorb the plate a, so that the raised end corner of the plate a can be flattened downward, and detection is performed again until the pressure values ​​detected by multiple pressure sensors 4 reach the first threshold value.

[0044] Specifically, the adsorption mechanism 6 is an electromagnet, and the plate a is an iron plate. By energizing the electromagnet, the electromagnet becomes magnetic and adsorbs the plate a, so that the raised end of the plate a can be laid flat.

[0045] In some embodiments, a limit block 11 is further provided on the machine 1 , and the limit block 11 is used to abut against the side of the first part 221 away from the plate a. When the pressure detected by the pressure sensor 4 is greater than the first threshold, the limit block 11 abuts against the first part 221 .

[0046] In the present application, the limit block 11 and the pressure sensor 4 are arranged side by side, and both are abutted against the side of the first part 221 away from the plate a. When the flip plate 22 rotates to the first state, the first part 221 of the flip plate 22 first abuts against the pressure sensor 4, and then as the pressure on the pressure sensor 4 gradually increases to the first threshold value, the first part 221 abuts against the limit block 11 to prevent the flip plate 22 from continuing to rotate, thereby completing the positioning of the plate a and protecting the pressure sensor 4 to avoid the situation where the pressure sensor 4 is impacted due to the deflection of the plate a.

[0047] In some embodiments, the first positioning mechanism 2 further includes an elastic member 23 , one end of the elastic member 23 is connected to the fixing frame 21 , and the other end is connected to the flip plate 22 , so that the flip plate 22 is kept in the second state.

[0048] In the present application, the flip plate 22 can be pulled by the elastic member 23, so that the flip plate 22 is kept in the second state at ordinary times. At this time, the second positioning mechanism 3 is located outside the positioning space, and will not affect the placement of the plate a into the positioning space. When the plate a is placed in the positioning space, the flip plate 22 is rotated to the first state by the gravity of the plate a itself. After the welding is completed, the plate a is removed, and the flip plate 22 automatically returns to the second state through the elastic member 23.

[0049] Specifically, the elastic member 23 is a tension spring.

[0050] In some embodiments, the flip plate 22 also includes a third part 223, the third part 223 is connected to one end of the first part 221 away from the second part 222, the elastic member 23 is connected to the end of the third part 223, and the connecting plate 31 of the second positioning mechanism 3 is connected to the third part 223.

[0051] In the present application, the third portion 223 is arranged at an angle to the first portion 221, so that when the flip plate 22 is in the second state, the second positioning mechanism 3 on the flip plate 22 can effectively avoid the space directly above the positioning space, thereby facilitating the placement of the plate a. By connecting the elastic member 23 to the end of the third portion 223, the pulling force on the flip plate 22 can be ensured.

[0052] Specifically, a stopper is provided on the fixing frame 21 to limit the flip plate 22 that rotates to the second state. When the elastic member 23 pulls the flip plate 22 to rotate, the stopper limits the flip plate 22 to maintain the stability of the flip plate 22.

[0053] In some embodiments, the connecting plate 31 is connected to two flip plates 22 located on the same side of the plate a, and a plurality of positioning components 32 are disposed on the connecting plate 31 , and the plurality of positioning components 32 are spaced apart along the length direction of the connecting plate 31 .

[0054] Specifically, eight first positioning mechanisms 2 are provided, and two first positioning mechanisms 2 are provided as a group on one side of the plate a. The connecting plate 31 is connected to the two flip plates 22 of the two first positioning mechanisms 2. There are four connecting plates 31 in total, and the number of positioning components 32 is set on each connecting plate 31 according to the needs.

[0055] Specifically, the positioning component 32 is detachably connected to the connecting plate 31 , and the positioning component 32 can be replaced or adjusted in position according to actual conditions to meet the positioning requirements for different types of products.

[0056] In some embodiments, when the flip plate 22 of the first positioning mechanism 2 is in the first state, the positioning hole 321 of the positioning component 32 is arranged in the vertical direction, and the second positioning mechanism 3 also includes a clamping component 33 arranged on the positioning component 32, and the clamping component 33 is used to fix the positioned welded part b.

[0057] In the present application, the welding part b is a pipe fitting. When the flip plate 22 is in the first state, the first part 221 is in a vertical state for positioning the outer edge of the plate a, and the positioning hole 321 is also in a vertical state. After the welding part b is inserted into the positioning hole 321 and abuts against the plate a, it can ensure that the pipe fitting is in a vertical state, thereby ensuring that the pipe fitting and the plate a remain in contact, thereby ensuring the positioning effect of the pipe fitting and the plate a.

[0058] The self-positioning tooling positions the plate a through multiple first positioning mechanisms 2. When the plate a is placed in the positioning space, the first parts 221 of the multiple flip plates 22 abut against the outer periphery of the plate a, and the second parts 222 of the flip plates 22 abut against the bottom of the plate a to support the plate a, thereby completing the positioning of the plate a. At this time, the second positioning mechanism 3 connected to the flip plate 22 positions the weldment b through the positioning hole 321, and can automatically complete the positioning of the plate a and the weldment b. The operation is simple and the work efficiency is improved.

[0059] The embodiment of the present application provides a plate processing device, including: the above-mentioned self-positioning tooling; a welding mechanism, used to weld the positioned plate a and the weldment b; and a lifting mechanism 7, arranged on the machine platform 1 of the self-positioning tooling, used to lift the welded plate a.

[0060] In the present application, the welding mechanism is a welding robot (not shown), which welds the positioned plate a and weldment b according to a set program, so it is necessary to ensure the positioning accuracy of plate a and the positioning accuracy between plate a and weldment b. When welding is completed, the plate a is lifted up by the lifting mechanism 7 to complete the unloading. The plate a can be transported by a transfer robot, which will not be described in detail here.
