[0031] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] See also Figures 1 to 4 The embodiment of the present application provides an anti-error identification device for assembly of welding sub-components and an identification method thereof, which can solve the problem in the related art that welding sub-components are not easy to be identified when they are reversely installed.

[0033] In the first aspect, an embodiment of the present application provides an error-proofing identification device for assembly of welding sub-components, which includes: an active power source 1, an active component and a detection component, the active power source 1 is used to be installed on a welding device and to support a stamping part 7, the output shaft of the active power source 1 has a first extension length and a second extension length; the active component is connected to the output shaft of the active power source 1, and the active power source 1 can drive the active component to move to contact with the welding sub-component 5; the detection component is used to collect the extension length of the output shaft of the active power source 1; when the active component is in contact with the welding sub-component 5, the output shaft of the active power source 1 is the first extension length, the welding sub-component 5 is installed properly, and the detection component does not issue an alarm; when the active component is in contact with the welding sub-component 5, the output shaft of the active power source 1 is the second extension length, the welding sub-component 5 is installed reversely, and the detection component issues an alarm.

[0034] In the present application, the active power source 1 is an original part on the welding device. An active component is arranged at the gap between the active power source 1 and the welding sub-component 5 to be welded on the welding device, so that the welding device can perform error-proof identification on the assembly of the welding sub-component 5. When the active component is in contact with the welding sub-component 5, the output shaft of the active power source 1 is at a first extended length, indicating that the welding sub-component 5 is properly installed. When the active component is in contact with the welding sub-component 5, the output shaft of the active power source 1 is at a second extended length, indicating that the welding sub-component 5 is reversed. The alarm situation of the detection component is used to remind the staff, so that the staff can identify the normal and reverse installation of the welding sub-component 5.

[0035] The movable power source 1 is used to abut and fix the stamping part 7 on the welding device. After the stamping part 7 is fixed, the welding sub-component 5 is welded to the stamping part 7. Therefore, the movable power source 1 is an original component of the welding device. The output shaft of the movable power source 1 is fixed with a connecting block, and the connecting block is fixed with both a supporting rod and a movable component. When the movable power source 1 is working, it can simultaneously drive the supporting rod to approach the stamping part 7 and drive the movable component to contact the welding sub-component 5.

[0036] See also Figure 3 and Figure 4 As shown, Figure 3 This is a schematic diagram of the assembly of the welding sub-component 5. Figure 4 It is a schematic diagram of the reverse installation of the welding sub-component 5. The horizontal plane at the lowest point of the bottom end of the welding sub-component 5 when the welding sub-component 5 is installed upright is located above the horizontal plane at the lowest point of the bottom end of the welding sub-component 5 when the welding sub-component 5 is installed reversely.

[0037] The movable component is set to have a starting position, a first position, and a second position. The second position is located between the first position and the starting position. When the welding sub-component 5 is installed upright, the movable power source 1 drives the movable component to move, and when the movable component contacts the welding sub-component 5, the output shaft of the movable power source 1 is the first extension length, and the movable component is in the first position, at which time the detection component does not issue an alarm; when the welding sub-component 5 is installed reversely, the movable power source 1 drives the movable component to move, and when the movable component contacts the welding sub-component 5, the output shaft of the movable power source 1 is the second extension length, and the movable component is in the second position, at which time the detection component issues an alarm.

[0038] It should be noted that since the second position is between the first position and the starting position, the second extension length is less than the first extension length. When the welding sub-assembly 5 is reversed, the movable assembly moves to the second position and is blocked by the welding sub-assembly 5 and cannot continue to move to the first position.

[0039] On the basis of the above embodiments, in this embodiment, the movable component includes: a first movable part 2 and a second movable part 4, the first movable part 2 is connected to the output shaft of the movable power source 1, and the movable power source 1 can drive the first movable part 2 to move in the horizontal direction; the second movable part 4 is used to be arranged on the welding device, and is located below the welding sub-component 5, and the top of the second movable part 4 is the welding sub-component contact end, the second movable part 4 is connected to the first movable part 2, and the first movable part 2 can drive the second movable part 4 to move in the vertical direction; wherein, the second movable part 4 has a starting position, a first position and a second position, the second position is located above the starting position, and the first position is located above the second position.

[0040] Specifically, the first movable member 2 is connected to the movable power source 1, and the second movable member 4 is connected to the welding device, and the second movable member 4 can move up and down relative to the welding device. The moving direction of the first movable member 2 is shown in FIG. Figure 2As shown, Figure 2 The X direction indicates the moving direction of the first movable member 2 in this embodiment.

[0041] After being fitted with the stamping part 7, the welding sub-component 5 is located above the first movable part 2. Since the horizontal plane at the lowest point of the bottom end of the welding sub-component 5 when the welding sub-component 5 is installed upright is above the horizontal plane at the lowest point of the bottom end of the welding sub-component 5 when the welding sub-component 5 is installed reversely, when the welding sub-component 5 is installed reversely and the contact end of the welding sub-component contacts with the welding sub-component 5, the second movable part 4 is in the second position, and the welding sub-component 5 blocks the second movable part 4 from moving from the second position to the first position.

[0042] Furthermore, when the welding sub-component 5 blocks the second movable part 4 from moving from the second position to the first position, the output shaft of the movable power source 1 cannot be extended from the second extended length to the first extended length. When the detection component detects that the extended length of the output shaft of the movable power source 1 has not changed within the set time, the detection component will begin to judge the extended length of the output shaft of the movable power source 1 at this time. Generally, when the welding sub-component 5 is reversely installed, since the output shaft of the movable power source 1 cannot be extended from the second extended length to the first extended length, the extended length of the output shaft of the movable power source 1 will be judged at this time; when the welding sub-component 5 is installed upright, since the movable component has moved to the first position and contacts with the welding sub-component 5, it cannot continue to move up, so the output shaft of the movable power source 1 cannot continue to extend at this time, and the extended length of the output shaft of the movable power source 1 will be judged at this time.

[0043] On this basis, in order to enable the second movable part 4 to move vertically when the first movable part 2 moves horizontally so as to reduce the space occupied, a through groove 40 is opened on the second movable part 4, and the first movable part 2 can pass through the through groove 40 and be slidably connected with the through groove 40; at the same time, the top end of the inner wall of the through groove 40 is an inclined surface, and the bottom end of the first movable part 2 is provided with a push inclined surface 20, and the push inclined surface 20 is in contact with the top end of the inner wall of the through groove 40.

[0044] See also Figure 2 As shown, when the first movable member 2 moves horizontally along the X direction, the pushing inclined surface 20 contacts the top of the inner wall of the through groove 40 and pushes the second movable member 4 to move upward.

[0045] Furthermore, the movable component also includes a fixed block 3 , which is used to be arranged on the welding device, and the second movable member 4 is slidably connected to the inside of the fixed block 3 .

[0046] Specifically, in order to ensure the stability of the second movable member 4 when it moves, a mounting groove is penetrated in the middle of the fixed block 3 along the moving direction of the first movable member 2, so that the fixed block 3 is a "U"-shaped structure, and the second movable member 4 is slidably connected inside the mounting groove. The purpose of providing the mounting groove is to allow the first movable member 2 to pass through the mounting groove, plug into the through groove 40, and drive the second movable member 4 to move up and down.

[0047] In order to further ensure the stability of the second movable part 4 when it moves, a spring is arranged between the bottom end of the inner wall of the fixed block 3 and the bottom end of the second movable part 4, and a spring can be arranged between the bottom end of the inner wall of the installation groove and the bottom end of the second movable part 4. The second movable part 4 is limited again by the spring to avoid misalignment of the second movable part 4 with the fixed block 3 when it moves.

[0048] Based on the above embodiments, in this embodiment:

[0049] In some possible embodiments, the mobile power source 1 includes a cylinder, and the cylinder output shaft has a first extension length and a second extension length;

[0050] The detection assembly includes a magnetic switch 6 disposed on the cylinder, and the magnetic switch 6 is electrically connected to the cylinder;

[0051] When the welding sub-component 5 is installed upright and the movable component is in contact with the welding sub-component 5, the cylinder output shaft is at the first extension length, and the magnetic switch 6 is off; when the welding sub-component 5 is installed reversely and the movable component is in contact with the welding sub-component 5, the cylinder output shaft is at the second extension length, and the magnetic switch 6 is on.

[0052] Specifically, when the magnetic switch 6 detects that the extended length of the cylinder output shaft has not changed within the set time, and the cylinder output shaft is extended to the first length, it indicates that the second movable part 4 is not blocked when it moves from the second position to the first position, and the welding sub-component 5 is not installed upside down, so the magnetic switch 6 does not light up for prompting; when the magnetic switch 6 detects that the extended length of the cylinder output shaft has not changed within the set time, and the cylinder output shaft is extended to the second length, it indicates that the second movable part 4 is blocked by the welding sub-component 5 when it moves from the second position to the first position, and the welding sub-component 5 is installed upside down, so the magnetic switch 6 lights up for prompting.

[0053] In some other possible embodiments, the active power source 1 includes a cylinder, and the cylinder output shaft has a first extension length and a second extension length; the detection component includes a pressure sensor, a controller and an alarm bell, and the pressure sensor is arranged on the active component and at a position in contact with the welding sub-component 5, and the controller is connected to the pressure sensor, the alarm bell and the cylinder. In this embodiment, the detection component does not need to detect whether the extension length of the output shaft of the active power source 1 changes within a set time, and the pressure sensor is arranged on the second active component 4, and the pressure sensor is in contact with the welding sub-component 5. When the pressure sensor is in contact with the welding sub-component 5, the controller controls the cylinder to stop working, and the detection component also includes a judgment module, at which time the judgment module judges the extension length of the cylinder output shaft, when the cylinder output shaft is the first extension length, the controller does not issue an instruction, and the alarm bell does not sound an alarm, when the cylinder output shaft is the second extension length, the controller sends an alarm instruction to the alarm bell, and the alarm bell sounds an alarm.

[0054] In summary, in this application, an error prevention device is designed based on the difference between the front and back of the welding sub-component 5: the horizontal plane at the lowest point of the bottom end of the welding sub-component 5 when the welding sub-component 5 is installed forwardly is located above the horizontal plane at the lowest point of the bottom end of the welding sub-component 5 when the welding sub-component 5 is installed reversely, and the original active power source 1 and the original space in the welding device are utilized to achieve the error prevention goal. After the welding of the welding sub-component 5 is completed, the retreat of the active power source 1 will not affect the picking up of other processes.

[0055] In a second aspect, an embodiment of the present application provides a method for error-proofing identification for assembly of welding sub-components, which includes:

[0056] 101: Provide an error-proofing identification device for assembly of a welding sub-component provided in any of the above embodiments of the present application;

[0057] 102: The detection component determines the extended length of the output shaft of the active power source 1 when the active power source 1 drives the active component to move to contact the welding sub-component 5, and the extended length of the output shaft of the active power source 1;

[0058] 103: If the output shaft of the movable power source 1 is at the first extension length, the detection component determines that the welding sub-component 5 is properly installed, and the detection component does not issue an alarm;

[0059] 104: If the output shaft of the active power source 1 is at the second extension length, the detection component determines that the welding sub-component 5 is reversely installed, and the detection component issues an alarm.

[0060] In the present application, the active power source 1 is an original part on the welding device. An active component is arranged at the gap between the active power source 1 and the welding sub-component 5 to be welded on the welding device, so that the welding device can perform error-proof identification on the assembly of the welding sub-component 5. When the active component is in contact with the welding sub-component 5, the output shaft of the active power source 1 is at a first extended length, indicating that the welding sub-component 5 is properly installed. When the active component is in contact with the welding sub-component 5, the output shaft of the active power source 1 is at a second extended length, indicating that the welding sub-component 5 is reversed. The alarm situation of the detection component is used to remind the staff, so that the staff can identify the normal and reverse installation of the welding sub-component 5.

[0061] See also Figure 3 and Figure 4 As shown, Figure 3 This is a schematic diagram of the assembly of the welding sub-component 5. Figure 4 It is a schematic diagram of the reverse installation of the welding sub-component 5. The horizontal plane at the lowest point of the bottom end of the welding sub-component 5 when the welding sub-component 5 is installed upright is located above the horizontal plane at the lowest point of the bottom end of the welding sub-component 5 when the welding sub-component 5 is installed reversely.

[0062] The movable component is set to have a starting position, a first position, and a second position. The second position is located between the first position and the starting position. When the welding sub-component 5 is installed upright, the movable power source 1 drives the movable component to move, and when the movable component contacts the welding sub-component 5, the output shaft of the movable power source 1 is the first extension length, and the movable component is in the first position, at which time the detection component does not issue an alarm; when the welding sub-component 5 is installed reversely, the movable power source 1 drives the movable component to move, and when the movable component contacts the welding sub-component 5, the output shaft of the movable power source 1 is the second extension length, and the movable component is in the second position, at which time the detection component issues an alarm.

[0063] It should be noted that since the second position is between the first position and the starting position, the second extension length is less than the first extension length. When the welding sub-assembly 5 is reversed, the movable assembly moves to the second position and is blocked by the welding sub-assembly 5 and cannot continue to move to the first position.

[0064] On the basis of the above embodiments, in this embodiment, the movable component includes: a first movable part 2 and a second movable part 4, the first movable part 2 is connected to the output shaft of the movable power source 1, and the movable power source 1 can drive the first movable part 2 to move in the horizontal direction; the second movable part 4 is used to be arranged on the welding device, and is located below the welding sub-component 5, and the top of the second movable part 4 is the welding sub-component contact end, the second movable part 4 is connected to the first movable part 2, and the first movable part 2 can drive the second movable part 4 to move in the vertical direction; wherein, the second movable part 4 has a starting position, a first position and a second position, the second position is located above the starting position, and the first position is located above the second position.

[0065] Specifically, the first movable member 2 is connected to the movable power source 1, and the second movable member 4 is connected to the welding device, and the second movable member 4 can move up and down relative to the welding device. The moving direction of the first movable member 2 is shown in FIG. Figure 2 As shown, Figure 2 The X direction indicates the moving direction of the first movable member 2 in this embodiment.

[0066] After being fitted with the stamping part 7, the welding sub-component 5 is located above the first movable part 2. Since the horizontal plane at the lowest point of the bottom end of the welding sub-component 5 when the welding sub-component 5 is installed upright is above the horizontal plane at the lowest point of the bottom end of the welding sub-component 5 when the welding sub-component 5 is installed reversely, when the welding sub-component 5 is installed reversely and the contact end of the welding sub-component contacts with the welding sub-component 5, the second movable part 4 is in the second position, and the welding sub-component 5 blocks the second movable part 4 from moving from the second position to the first position.

[0067] Furthermore, when the welding sub-component 5 blocks the second movable part 4 from moving from the second position to the first position, the output shaft of the movable power source 1 cannot be extended from the second extended length to the first extended length. When the detection component detects that the extended length of the output shaft of the movable power source 1 has not changed within the set time, the detection component will begin to judge the extended length of the output shaft of the movable power source 1 at this time. Generally, when the welding sub-component 5 is reversely installed, since the output shaft of the movable power source 1 cannot be extended from the second extended length to the first extended length, the extended length of the output shaft of the movable power source 1 will be judged at this time; when the welding sub-component 5 is installed upright, since the movable component has moved to the first position and contacts with the welding sub-component 5, it cannot continue to move up, so the output shaft of the movable power source 1 cannot continue to extend at this time, and the extended length of the output shaft of the movable power source 1 will be judged at this time.

[0068] On this basis, in order to enable the second movable part 4 to move vertically when the first movable part 2 moves horizontally so as to reduce the space occupied, a through groove 40 is opened on the second movable part 4, and the first movable part 2 can pass through the through groove 40 and be slidably connected with the through groove 40; at the same time, the top end of the inner wall of the through groove 40 is an inclined surface, and the bottom end of the first movable part 2 is provided with a push inclined surface 20, and the push inclined surface 20 is in contact with the top end of the inner wall of the through groove 40.

[0069] See also Figure 2 As shown, when the first movable member 2 moves horizontally along the X direction, the pushing inclined surface 20 contacts the top of the inner wall of the through groove 40 and pushes the second movable member 4 to move upward.

[0070] Furthermore, the movable component also includes a fixed block 3 , which is used to be arranged on the welding device, and the second movable member 4 is slidably connected to the inside of the fixed block 3 .

[0071] Specifically, in order to ensure the stability of the second movable member 4 when it moves, a mounting groove is penetrated in the middle of the fixed block 3 along the moving direction of the first movable member 2, so that the fixed block 3 is a "U"-shaped structure, and the second movable member 4 is slidably connected inside the mounting groove. The purpose of providing the mounting groove is to allow the first movable member 2 to pass through the mounting groove, plug into the through groove 40, and drive the second movable member 4 to move up and down.

[0072] In order to further ensure the stability of the second movable part 4 when it moves, a spring is arranged between the bottom end of the inner wall of the fixed block 3 and the bottom end of the second movable part 4, and a spring can be arranged between the bottom end of the inner wall of the installation groove and the bottom end of the second movable part 4. The second movable part 4 is limited again by the spring to avoid misalignment of the second movable part 4 with the fixed block 3 when it moves.

[0074] In some possible embodiments, the mobile power source 1 includes a cylinder, and the cylinder output shaft has a first extension length and a second extension length;

[0075] The detection assembly includes a magnetic switch 6 disposed on the cylinder, and the magnetic switch 6 is electrically connected to the cylinder;

[0076] When the welding sub-component 5 is installed upright and the movable component is in contact with the welding sub-component 5, the cylinder output shaft is at the first extension length, and the magnetic switch 6 is off; when the welding sub-component 5 is installed reversely and the movable component is in contact with the welding sub-component 5, the cylinder output shaft is at the second extension length, and the magnetic switch 6 is on.

[0077] Specifically, when the magnetic switch 6 detects that the extended length of the cylinder output shaft has not changed within the set time, and the cylinder output shaft is extended to the first length, it indicates that the second movable part 4 is not blocked when it moves from the second position to the first position, and the welding sub-component 5 is not installed upside down, so the magnetic switch 6 does not light up for prompting; when the magnetic switch 6 detects that the extended length of the cylinder output shaft has not changed within the set time, and the cylinder output shaft is extended to the second length, it indicates that the second movable part 4 is blocked by the welding sub-component 5 when it moves from the second position to the first position, and the welding sub-component 5 is installed upside down, so the magnetic switch 6 lights up for prompting.

[0078] In some other possible embodiments, the active power source 1 includes a cylinder, and the cylinder output shaft has a first extension length and a second extension length; the detection component includes a pressure sensor, a controller and an alarm bell, and the pressure sensor is arranged on the active component and at a position in contact with the welding sub-component 5, and the controller is connected to the pressure sensor, the alarm bell and the cylinder. In this embodiment, the detection component does not need to detect whether the extension length of the output shaft of the active power source 1 changes within a set time, and the pressure sensor is arranged on the second active component 4, and the pressure sensor is in contact with the welding sub-component 5. When the pressure sensor is in contact with the welding sub-component 5, the controller controls the cylinder to stop working, and the detection component also includes a judgment module, at which time the judgment module judges the extension length of the cylinder output shaft, when the cylinder output shaft is the first extension length, the controller does not issue an instruction, and the alarm bell does not sound an alarm, when the cylinder output shaft is the second extension length, the controller sends an alarm instruction to the alarm bell, and the alarm bell sounds an alarm.

[0079] In summary, in this application, an error prevention device is designed based on the difference between the front and back of the welding sub-component 5: the horizontal plane at the lowest point of the bottom end of the welding sub-component 5 when the welding sub-component 5 is installed forwardly is located above the horizontal plane at the lowest point of the bottom end of the welding sub-component 5 when the welding sub-component 5 is installed reversely, and the original active power source 1 and the original space in the welding device are utilized to achieve the error prevention goal. After the welding of the welding sub-component 5 is completed, the retreat of the active power source 1 will not affect the picking up of other processes.
