Description

Technical Field

[0001] The present invention relates to the technical field of tooling, and in particular to a hinge error prevention method and a hinge error prevention mechanism. Background Art

[0002] With the enormous demand in the automotive market and the continuous advancement of industrial automation, flexible, high-speed production models for multiple vehicle models are becoming increasingly important in welding workshops. This is particularly true because the hinge components on all four doors of a vehicle are relatively similar—the only difference between the front and rear doors, and between different models, is the aperture diameter—which creates a risk of mixed assembly. Traditional hinge error prevention methods utilize photoelectric switches for hinge identification. However, these methods require an external PLC controller, which requires significant modifications to the vehicle tooling (which is purely pneumatic). Summary of the Invention

[0003] Based on this, it is necessary to provide a hinge error proofing method and a hinge error proofing mechanism to address the problem that the traditional hinge error proofing method requires a huge amount of modification to the vehicle tooling (pure pneumatic).

[0004] The technical solution is as follows:

[0005] In one aspect, a hinge error prevention method is provided, comprising:

[0006] Installing the hinge at a first preset position on the mounting platform, and arranging the detection member corresponding to the positioning hole of the hinge;

[0007] The detection part moves toward the direction close to the installation platform so that the plug-in part of the detection part is plugged into the positioning hole, and it is determined whether the interference part of the detection part can interfere with the hinge. If the interference part interferes with the hinge, the installed hinge is correct. If the interference part cannot interfere with the hinge, the installed hinge is incorrect.

[0008] The technical solution is further described below:

[0009] In one embodiment, the detection member is moved in a direction close to the installation platform so that the plug-in portion of the detection member is plugged into and matched with the positioning hole, and it is determined whether the interference portion of the detection member can interfere with and match with the hinge. If the interference portion interferes with and matches with the hinge, the hinge is installed correctly; if the interference portion cannot interfere with and match with the hinge, the hinge is installed incorrectly. The steps include:

[0010] The first driving member drives the first trigger member and the detection member to move synchronously toward the direction close to the installation platform, so that the plug-in portion of the detection member is plugged into the positioning hole, and determines whether the first trigger member can trigger the first control valve. If the interference portion interferes with the hinge, the first trigger member cannot continue to move toward the direction close to the installation platform, so that the first trigger member is spaced apart from the first control valve so as to be unable to trigger the first control valve, then the installed hinge is correct. If the interference portion cannot interfere with the hinge, the first trigger member can continue to move toward the direction close to the installation platform, so that the first trigger member triggers the first control valve, then the installed hinge is incorrect.

[0011] In one embodiment, the first driving member drives the first trigger member and the detection member to move synchronously toward the direction close to the installation platform, so that the plug-in portion of the detection member is plugged into the positioning hole, and it is determined whether the first trigger member can trigger the first control valve. If the interference portion interferes with the hinge, the first trigger member cannot continue to move toward the direction close to the installation platform, so that the first trigger member is spaced apart from the first control valve and cannot trigger the first control valve, then the hinge is installed correctly. If the interference portion cannot interfere with the hinge, the first trigger member can continue to move toward the direction close to the installation platform, so that the first trigger member triggers the first control valve, then the hinge is installed incorrectly. After the step, the method further includes:

[0012] When the hinge is installed correctly, the first control valve corresponding to the first driving member remains in a conducting state, so that the first driving member can drive the detection member and the first trigger member to reset, and the hinge can proceed to the next process; when the hinge is installed incorrectly, the first control valve corresponding to the first driving member is switched from a conducting state to a closed state, so that the first driving member cannot drive the detection member and the first trigger member to reset, and the hinge cannot proceed to the next process.

[0013] In one embodiment, before the steps of installing the hinge at the first preset position of the mounting platform and arranging the detection member to correspond to the positioning hole of the hinge, the method further includes:

[0014] The correct hinge is installed at the first preset position of the mounting platform, and the first driving member drives the first trigger member and the detection member to move synchronously toward the mounting platform, so that the plug-in portion of the detection member is plug-fitted with the positioning hole. If the first trigger member can trigger the first control valve, the first control valve is driven to move toward the direction away from the mounting platform to ensure that the first trigger member cannot trigger the first control valve when the installed hinge is correct. If not, the first control valve is not driven to move. The incorrect hinge is installed at the first preset position of the mounting platform, and the first driving member drives the first trigger member and the detection member to move synchronously toward the mounting platform, so that the plug-in portion of the detection member is plug-fitted with the positioning hole. If the first trigger member cannot trigger the first control valve, the first control valve is driven to move toward the direction close to the mounting platform to ensure that the first trigger member can trigger the first control valve when the installed hinge is incorrect. If not, the first control valve is not driven to move.

[0015] In one embodiment, the step of installing the hinge at a first preset position of the mounting platform and arranging the detection member corresponding to the positioning hole of the hinge includes:

[0016] Install the hinge at a first preset position on the mounting platform;

[0017] The second driving member drives the limiting assembly to move toward the direction close to the mounting platform, so that the limiting assembly can cooperate with the hinge to limit the position of the hinge relative to the mounting platform, and the detection member is set corresponding to the positioning hole of the hinge.

[0018] In one embodiment, the second driving member drives the limiting assembly to move toward the mounting platform so that the limiting assembly can cooperate with the hinge to limit the position of the hinge relative to the mounting platform, and the step of setting the detection member corresponding to the positioning hole of the hinge includes:

[0019] The second driving member drives the limiting assembly, the third driving member and the detecting member to move synchronously toward the direction close to the mounting platform;

[0020] When the limit assembly moves to a position that triggers the second control valve corresponding to the second drive member, the second drive member stops driving the limit assembly, the third drive member and the detection member to move, and the limit assembly cooperates with the hinge to limit the position of the hinge relative to the mounting platform, and the detection member is arranged correspondingly to the positioning hole of the hinge.

[0021] In one embodiment, the detection member is moved in a direction close to the installation platform so that the plug-in portion of the detection member is plugged into and matched with the positioning hole, and it is determined whether the interference portion of the detection member can interfere with and match with the hinge. If the interference portion interferes with and matches with the hinge, the hinge is installed correctly; if the interference portion cannot interfere with and match with the hinge, the hinge is installed incorrectly. The steps include:

[0022] The third driving member drives the second trigger member and the detection member to move synchronously toward the direction close to the installation platform, so that the plug-in portion of the detection member is plugged into the positioning hole, and determines whether the second trigger member can trigger the third control valve. If the interference portion interferes with the hinge, the second trigger member cannot continue to move toward the direction close to the installation platform, so that the second trigger member and the third control valve are spaced apart so as not to trigger the third control valve, then the installed hinge is correct. If the interference portion cannot interfere with the hinge, the second trigger member can continue to move toward the direction close to the installation platform, so that the second trigger member triggers the third control valve, then the installed hinge is incorrect.

[0023] In one embodiment, after the third driving member drives the second trigger member and the detection member to move synchronously toward the direction close to the mounting platform, so that the plug-in portion of the detection member is plugged into the positioning hole, and it is determined whether the second trigger member can trigger the third control valve, if the interference portion interferes with the hinge, the second trigger member cannot continue to move toward the direction close to the mounting platform, so that the second trigger member is spaced apart from the third control valve so as not to trigger the third control valve, then the hinge is installed correctly; if the interference portion cannot interfere with the hinge, the second trigger member can continue to move toward the direction close to the mounting platform, so that the second trigger member triggers the third control valve, then the hinge is installed incorrectly, the method further includes:

[0024] When the hinge is installed correctly, the third control valve corresponding to the second drive member remains in a closed state, so that the second drive member can limit the position of the hinge relative to the mounting platform through the limit assembly, and the hinge can proceed to the next process; when the hinge is installed incorrectly, the third control valve corresponding to the second drive member is switched from a closed state to a conductive state, so that the second drive member cannot limit the position of the hinge relative to the mounting platform through the limit assembly, and the hinge cannot proceed to the next process.

[0025] In one embodiment, before the steps of installing the hinge at the first preset position of the mounting platform and arranging the detection member to correspond to the positioning hole of the hinge, the method further includes:

[0026] The fourth driving member drives the mounting platform to move along the first direction to a second preset position.

[0027] In one embodiment, the step of the fourth driving member driving the mounting platform to move along the first direction to the second preset position includes:

[0028] The fourth driving member drives the mounting platform that is in contact with the fourth control valve to move in the first direction. When the mounting platform and the fourth control valve that is connected to the fourth driving member are separated, the fourth control valve is switched from an on state to a closed state, so that the fourth driving member stops driving the mounting platform to move in the first direction, so as to ensure that the mounting platform moves to the second preset position.

[0029] On the other hand, a hinge error prevention mechanism is provided for implementing the hinge error prevention method. The hinge error prevention mechanism includes a mounting platform and a detection part. The mounting platform is used to install the hinge. The detection part includes a plug-in part and a resistance part. The outer diameter of the resistance part is larger than the outer diameter of the plug-in part. The resistance part is located on the side of the plug-in part away from the mounting platform. The plug-in part and the resistance part can move back and forth synchronously in a direction close to or away from the mounting platform, so that the resistance part can be plugged into and matched with the positioning hole of the hinge, and the resistance part can selectively resist and match with the hinge.

[0030] In one embodiment, the hinge error prevention mechanism also includes a first driving member, a first trigger member and a first control valve. The first driving member is transmission-connected to the first trigger member and the detection member, so that the first trigger member and the detection member can synchronously move back and forth in a direction close to or away from the installation platform. The first control valve and the first trigger member are correspondingly arranged. When the interference portion interferes with the hinge, the first trigger member and the first control valve are spaced apart so as not to trigger the first control valve. When the interference portion cannot interfere with the hinge, the first trigger member can continue to move toward the direction close to the installation platform to trigger the first control valve.

[0031] In one embodiment, the first driving member is configured as a first telescopic cylinder, and the first control valve is used to connect the air source to the first telescopic cylinder so as to control the first telescopic cylinder and the air source to be connected or closed accordingly.

[0032] In one embodiment, the hinge error prevention mechanism also includes a second drive member, a limit assembly, a third drive member and a second control valve. The second drive member is transmission-connected to the limit assembly and the third drive member, and the third drive member is transmission-connected to the detection member, so that the limit assembly, the third drive member and the detection member can synchronously move back and forth in a direction close to or away from the installation platform. The second control valve and the limit assembly are correspondingly arranged. When the limit assembly moves to a position that triggers the second control valve, the second drive member stops driving the limit assembly, the third drive member and the detection member to move, and the limit assembly interferes with the hinge to limit the position of the hinge relative to the installation platform. The detection member and the positioning hole of the hinge are correspondingly arranged.

[0033] In one embodiment, the second driving member is configured as a flip cylinder, and the hinge error prevention mechanism also includes a second trigger member and a third control valve. The third driving member is transmission-connected to the second trigger member so that the second trigger member and the detection member can synchronously move back and forth in a direction approaching or away from the mounting platform. The third control valve is correspondingly configured to the second trigger member, and the third control valve is connected to the flip cylinder so as to be able to control the flip cylinder to maintain pressure or release pressure.

[0034] Compared with the traditional hinge error prevention method, the hinge error prevention method in the present application has at least the following advantages: (1) The hinge error prevention method in the present application can achieve the effect of error-proof installation by mechanical means, without the need for an external PLC electric controller, which reduces the modification of the vehicle model tooling, and reduces the cost and difficulty of the vehicle model tooling modification. (2) The hinge error prevention method in the present application only needs to add a corresponding hinge error prevention mechanism on the basis of the traditional vehicle model tooling, while retaining the original function of the vehicle model tooling, it can also accurately and reliably achieve the effect of error-proof installation, thereby improving the convenience and applicability of the vehicle model tooling. (3) By utilizing the aperture relationship between the detection part and the positioning holes on different hinges, the hinge error prevention installation can be achieved quickly and accurately, avoiding the situation where the door is damaged or scrapped due to the misalignment of the hinge installation, thereby improving the accuracy and reliability of the hinge error prevention mechanism.

[0046] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0047] like Figures 1 to 4 As shown, in one embodiment, a hinge error prevention method is provided, comprising the following steps:

[0048] S100: Install the hinge 200 at a first preset position on the mounting platform 100, and place the detection member 300 in correspondence with the positioning hole of the hinge 200. This ensures that the detection member 300 can be inserted into the positioning hole of the hinge 200, so as to facilitate subsequent detection of the aperture of the positioning hole.

[0049] It should be noted that the detection member 300 can be a stepped pin, a stepped shaft, a stepped tube, or other structure that can be plugged into the positioning hole and interfere with the hinge 200. Specifically, in this embodiment, the detection member 300 is a stepped pin. The diameter of the stepped pin can be flexibly adjusted according to actual needs.

[0050] It should be noted that the hinge error prevention method in this embodiment can be used to prevent the door hinge 200 in vehicles such as cars, commercial vehicles, buses, trucks, fuel vehicles, electric vehicles, and hybrid vehicles.

[0051] like Figure 5 As shown, specifically in this embodiment, S110, the hinge 200 is installed at a first preset position corresponding to the installation platform 100. In this way, the hinge 200 can be easily limited and tested later.

[0052] S120: The second driving member 700 drives the limiting assembly 800 to move toward the mounting platform 100, so that the limiting assembly 800 can cooperate with the hinge 200 to limit the position of the hinge 200 relative to the mounting platform 100, and the detection member 300 is arranged to correspond to the positioning hole of the hinge 200. In this way, the limiting assembly 800 can prevent the hinge 200 from moving relative to the mounting platform 100 during subsequent operations, ensuring that the detection member 300 can be plugged into and cooperated with the positioning hole of the hinge 200, thereby improving the reliability of the hinge error prevention mechanism 10 and facilitating the subsequent installation of the hinge 200 on the corresponding vehicle door.

[0053] like Figures 1 to 3 As shown, specifically in this embodiment, the limiting assembly 800 includes a first pressing block 810, a second pressing block 820 and a positioning pin 830. The first pressing block 810 is used to cooperate with the hinge 200 to limit the hinge 200 from moving in a first direction (such as Figure 1 The second pressing block 820 is used to cooperate with the hinge 200 to limit the hinge 200 from moving in the second direction (as shown in the direction of Y in FIG). Figure 1 The positioning pin 830 is used to engage with the through hole on the hinge 200 to limit the hinge 200 from moving in the third direction (as shown in the direction of X). Figure 1The hinge 200 is moved in the direction of Z in the middle (as shown in the Z direction in the middle), and any two of the first, second, and third directions are perpendicular to each other. The second driving member 700 can be a flip cylinder, which is in transmission cooperation with the first pressing block 810, the second pressing block 820, and the positioning pin 830, so that the first pressing block 810, the second pressing block 820, and the positioning pin 830 can be synchronously flipped toward the direction close to the mounting platform 100 to cooperate in limiting the position of the hinge 200 relative to the mounting platform 100, or the first pressing block 810, the second pressing block 820, and the positioning pin 830 can be synchronously flipped toward the direction away from the mounting platform 100 to release the restriction on the position of the hinge 200 relative to the mounting platform 100. In this way, the reliability and convenience of the hinge anti-error mechanism 10 are improved.

[0054] It should be noted that the first direction may be a direction perpendicular to the side of the mounting platform 100 for mounting the hinge 200 .

[0055] like Figure 7 As shown, specifically in this embodiment, at S121, the second driving member 700 drives the limiting assembly 800, the third driving member, and the detecting member 300 to move synchronously toward the mounting platform 100. Thus, when the limiting assembly 800 and the hinge 200 engage with each other, the third driving member and the detecting member 300 also simultaneously move to positions corresponding to the positioning holes of the hinge 200, thereby improving the installation efficiency and convenience of the hinge error prevention mechanism 10.

[0056] It should be noted that the third driving member may be a first telescopic cylinder, a telescopic hydraulic cylinder, an electric telescopic rod or other driving structures.

[0057] S122: When the limit assembly 800 moves to a position where it triggers the second control valve 900 corresponding to the second driving member 700, the second driving member 700 stops driving the limit assembly 800, the third driving member, and the detection member 300. The limit assembly 800 engages with the hinge 200 to restrict the position of the hinge 200 relative to the mounting platform 100. The detection member 300 is positioned corresponding to the positioning hole of the hinge 200. In this way, whether the limit assembly 800 has moved to a position where it engages with the hinge 200 is determined by whether the limit assembly 800 has triggered the second control valve 900, thereby improving the installation efficiency and reliability of the hinge error prevention mechanism 10.

[0058] S200, the detection member 300 moves in the direction close to the installation platform 100, so that the plug-in portion 310 of the detection member 300 is plugged into the positioning hole, and it is judged whether the interference portion 320 of the detection member 300 can interfere with the hinge 200. If the interference portion 320 interferes with the hinge 200, the installed hinge 200 is correct. If the interference portion 320 cannot interfere with the hinge 200, the installed hinge 200 is wrong. In this way, it is only necessary to add a corresponding hinge error-proofing mechanism 10 on the basis of the traditional vehicle model tooling, and the traditional vehicle model tooling does not need to be extensively improved to achieve the error-proofing installation of the hinge 200, which improves the convenience of the vehicle model tooling modification while reducing the modification cost of the vehicle model tooling. In addition, the hinge error-proofing method in this embodiment can also retain the structure and function of the traditional vehicle model tooling, thereby improving the applicability of the vehicle model tooling.

[0059] It should be noted that the hinge error-proofing mechanism 10 in this embodiment can be used independently of the vehicle body tooling, or can be provided in the vehicle body tooling to be used as a part of the vehicle body tooling.

[0060] It should be noted that when the incorrect hinge 200 is installed, the inner diameter of the positioning hole on the incorrect hinge 200 is larger than the outer diameter of the interference part 320, so that the interference part 320 will move into the corresponding positioning hole and cannot achieve interference cooperation with the hinge 200.

[0061] like Figure 6 As shown, specifically in this embodiment, S210, the first driving member 400 drives the first trigger member 500 and the detection member 300 to move synchronously toward the direction close to the installation platform 100, so that the plug-in portion 310 of the detection member 300 is plugged into the positioning hole, and determines whether the first trigger member 500 can trigger the first control valve 600. If the interference portion 320 interferes with the hinge 200, the first trigger member 500 cannot continue to move toward the direction close to the installation platform 100, so that the first trigger member 500 and the first control valve 600 are spaced apart so as not to trigger the first control valve 600, then the installed hinge 200 is correct. If the interference portion 320 cannot interfere with the hinge 200, the first trigger member 500 can continue to move toward the direction close to the installation platform 100, so that the first trigger member 500 triggers the first control valve 600, then the installed hinge 200 is incorrect. In this way, when the first trigger member 500 is used to trigger the first control valve 600, the first control valve 600 will generate a corresponding over-position signal, and when the first trigger member 500 cannot trigger the second control valve 900, the first control valve 600 will not generate a corresponding over-position signal, so that the operator can quickly determine whether the installed hinge 200 is correct.

[0062] It should be noted that the transition signal may be an electrical signal, an optical signal, an acoustic signal or other signals.

[0063] It should be noted that the first driving member 400 and the third driving member can be the same device, with different names used to distinguish different embodiments. The first triggering member 500 can be disposed on the first driving member 400 or on the detection member 300, as long as the first triggering member 500 and the detection member 300 can move synchronously back and forth in a direction toward or away from the mounting platform 100. The first triggering member 500 can be a triggering plate, a triggering rod, a triggering block, or other triggering structure.

[0064] S300. When the hinge 200 is installed correctly, the first control valve 600 corresponding to the first drive member 400 remains in an on state, allowing the first drive member 400 to drive the detection member 300 and the first trigger member 500 to reset, and the hinge 200 can proceed to the next process. When the hinge 200 is installed incorrectly, the first control valve 600 corresponding to the first drive member 400 switches from an on state to a closed state, making it impossible for the first drive member 400 to drive the detection member 300 and the first trigger member 500 to reset, and the hinge 200 cannot proceed to the next process. In this way, when the hinge 200 is installed incorrectly, the vehicle model tooling cannot proceed to the next process, preventing the vehicle door from being damaged or scrapped due to the installation of a misplaced hinge 200, and ensuring that the vehicle door can be installed with the correct hinge 200. In addition, the vehicle model tooling cannot proceed to the next process, making it easier for operators to promptly discover the incorrect installation of the hinge 200 and take corresponding measures.

[0065] like Figure 6 As shown, in one embodiment, before the steps of installing the hinge 200 at the first preset position on the mounting platform 100 and arranging the detection member 300 to correspond to the positioning hole of the hinge 200, the method further includes:

[0066] S400: Install the correct hinge 200 at the first preset position on the mounting platform 100. The first driving member 400 drives the first trigger member 500 and the detection member 300 to move synchronously toward the mounting platform 100, so that the plug-in portion 310 of the detection member 300 is plugged into the positioning hole. If the first trigger member 500 can trigger the first control valve 600, the first control valve 600 is driven to move away from the mounting platform 100 to ensure that the first trigger member 500 cannot trigger the first control valve 600 when the hinge 200 is installed correctly. If not, the first control valve 600 is not driven. Move; install the wrong hinge 200 at the first preset position of the installation platform 100, and the first driving member 400 drives the first trigger member 500 and the detection member 300 to move synchronously in the direction close to the installation platform 100, so that the plug-in portion 310 of the detection member 300 is plugged into the positioning hole. If the first trigger member 500 cannot trigger the first control valve 600, the first control valve 600 is driven to move in the direction close to the installation platform 100 to ensure that the first trigger member 500 can trigger the first control valve 600 when the installed hinge 200 is wrong. If not, the first control valve 600 is not driven to move. In this way, by adjusting the position of the first control valve 600 relative to the installation platform 100, it is ensured that the detection member 300 can accurately and reliably identify the hinge 200 that is installed incorrectly, thereby improving the reliability and accuracy of the hinge error prevention mechanism 10.

[0067] like Figure 7 As shown, in one embodiment, when the detection member 300 moves toward the direction close to the installation platform 100, the plug-in portion 310 of the detection member 300 is plugged into the positioning hole, and it is determined whether the interference portion 320 of the detection member 300 can interfere with the hinge 200. If the interference portion 320 interferes with the hinge 200, the installed hinge 200 is correct. If the interference portion 320 cannot interfere with the hinge 200, the installed hinge 200 is incorrect. The steps include:

[0068] S220, the third driving member drives the second trigger member and the detection member 300 to move synchronously toward the installation platform 100, so that the plug-in portion 310 of the detection member 300 is plugged into the positioning hole, and determines whether the second trigger member can trigger the third control valve. If the interference portion 320 interferes with the hinge 200, the second trigger member cannot continue to move toward the installation platform 100, so that the second trigger member and the third control valve are spaced apart so as not to trigger the third control valve, then the installed hinge 200 is correct. If the interference portion 320 cannot interfere with the hinge 200, the second trigger member can continue to move toward the installation platform 100, so that the second trigger member triggers the third control valve, then the installed hinge 200 is incorrect. In this way, when the third control valve is triggered by the second trigger member, the third control valve will generate a corresponding over-position signal, and when the second trigger member cannot trigger the third control valve, the third control valve will not generate a corresponding over-position signal, so that the operator can quickly determine whether the hinge 200 is installed correctly.

[0069] It should be noted that the second triggering member may be a triggering piece, a triggering rod, a triggering block or other triggering structures.

[0070] S500: When the hinge 200 is installed correctly, the third control valve corresponding to the second drive member 700 remains closed, allowing the second drive member 700 to limit the position of the hinge 200 relative to the mounting platform 100 through the limit assembly 800, and the hinge 200 can proceed to the next process. When the hinge 200 is installed incorrectly, the third control valve corresponding to the second drive member 700 switches from a closed state to an open state, making it impossible for the second drive member 700 to limit the position of the hinge 200 relative to the mounting platform 100 through the limit assembly 800, and the hinge 200 cannot proceed to the next process. In this way, when the hinge 200 is installed incorrectly, the limit assembly 800 cannot limit the position of the hinge 200 relative to the mounting platform 100, making it easy for the vehicle tooling to be unable to proceed to the next process due to movement of the hinge 200 relative to the mounting platform 100. This prevents the vehicle door from being damaged or scrapped due to the installation of a misplaced hinge 200, and ensures that the vehicle door can be installed with the correct hinge 200.

[0071] like Figure 6 In one embodiment, before the steps of installing the hinge 200 at the first preset position of the mounting platform 100 and arranging the detection member 300 to correspond to the positioning hole of the hinge 200, the method further includes:

[0072] At step S600, the fourth driving member 1000 drives the mounting platform 100 to move along the first direction to the second preset position. Once the hinge 200 is installed, the fourth driving member 1000 drives the mounting platform 100 to return to its original position, separating the mounting platform 100 from the hinge 200. This prevents interference between the mounting platform 100 and the hinge 200, ensuring smooth removal of the vehicle body tooling.

[0073] like Figure 7 As shown, specifically in this embodiment, at S610, the fourth driving member 1000 drives the mounting platform 100, which is in contact with the fourth control valve 1100, to move in the first direction. When the mounting platform 100 and the fourth control valve 1100, which is in contact with the fourth driving member 1000, are separated, the fourth control valve 1100 switches from an on state to a closed state, causing the fourth driving member 1000 to stop driving the mounting platform 100 in the first direction, thereby ensuring that the mounting platform 100 moves to the second preset position. In this way, the state switching of the fourth control valve 1100 ensures that the mounting platform 100 can accurately and quickly move to the second preset position.

[0074] Specifically, in this embodiment, the fourth driving member 1000 is configured as a second telescopic cylinder, and the fourth control valve 1100 is configured as a fourth air valve. The second telescopic cylinder is connected to the air source via the fourth air valve. Thus, when the mounting platform 100 contacts the fourth control valve 1100, the fourth control valve 1100 is in an open state, allowing the air source to supply air to the second telescopic cylinder through the fourth air valve, thereby driving the mounting platform 100 to move in the corresponding first direction. When the mounting platform 100 and the fourth control valve 1100 separate, the fourth air valve is triggered, switching from an open state to a closed state, preventing the air source from supplying air to the second telescopic cylinder. The mounting platform 100 remains fixed relative to the second telescopic cylinder, thereby ensuring that the limit assembly 800 can quickly and accurately move to the second preset position and cooperate with the mounting platform 100 to clamp the hinge 200.

[0075] It should be noted that the second driving member 700 , the fourth driving member 1000 , the second control valve 900 , the third control valve and the fourth control valve 1100 are all connected to the installation body 1200 .

[0076] It should be noted that the second preset position refers to the position of the mounting platform 100 relative to the mounting body 1200 when the detection member 300 is plugged into the positioning hole of the hinge 200 .

[0077] Compared with the traditional hinge error prevention method, the hinge error prevention method in the present application has at least the following advantages: (1) The hinge error prevention method in the present application can achieve the effect of error prevention installation by mechanical means, does not require an external PLC electric controller, reduces the modification of the vehicle model tooling, and reduces the cost and difficulty of the vehicle model tooling modification. (2) The hinge error prevention method in the present application only needs to add a corresponding hinge error prevention mechanism 10 on the basis of the traditional vehicle model tooling, while retaining the original function of the vehicle model tooling, it can also accurately and reliably achieve the effect of error prevention installation, and improve the convenience and applicability of the vehicle model tooling. (3) By utilizing the aperture relationship between the detection part 300 and the positioning holes on different hinges 200, the hinge error prevention installation can be achieved quickly and accurately, avoiding the situation where the door is damaged or scrapped due to the misalignment of the hinge installation, and improving the accuracy and reliability of the hinge error prevention mechanism 10.

[0078] like Figure 1 、 Figure 2 and Figure 3 As shown, in one embodiment, a hinge 200 anti-error installation mechanism is provided, and the hinge anti-error mechanism 10 includes a mounting platform 100 and a detection member 300. The mounting platform 100 is used to install the hinge 200. The detection member 300 includes a plug-in portion 310 and a resistance portion 320. The outer diameter of the resistance portion 320 is larger than the outer diameter of the plug-in portion 310. The resistance portion 320 is located on the side of the plug-in portion 310 away from the mounting platform 100. The plug-in portion 310 and the resistance portion 320 can synchronously move back and forth in a direction close to or away from the mounting platform 100, so that the resistance portion 320 can be plugged into and matched with the positioning hole of the hinge 200, and the resistance portion 320 can selectively resist and match with the hinge 200.

[0079] When the hinge error prevention mechanism 10 in the above embodiment is used, the hinge 200 is installed at the first preset position of the installation platform 100, and the detection member 300 is set corresponding to the positioning hole of the hinge 200. Then, the plug-in portion 310 and the interference portion 320 are driven to move synchronously in the direction close to the installation platform 100, so that the plug-in portion 310 is plugged into the positioning hole, and it is judged whether the interference portion 320 can interfere with the hinge 200. If the interference portion 320 interferes with the hinge 200, the installed hinge 200 is correct. If the interference portion 320 cannot interfere with the hinge 200, the installed hinge 200 is incorrect. Compared with the traditional hinge error prevention mechanism 10, the hinge error prevention mechanism 10 in the present application can achieve the effect of error-proofing installation by mechanical means, and does not require an external PLC electrical controller, which reduces the modification of the vehicle model tooling and reduces the cost of vehicle model tooling modification. In addition, the hinge 200 anti-error method in the present application can retain the original function of the vehicle body tooling while accurately and reliably achieving the effect of anti-error installation, thereby improving the convenience and applicability of the vehicle body tooling.

[0080] like Figure 1 、 Figure 2 and Figure 3 As shown, further, the hinge error prevention mechanism 10 also includes a first driving member 400, a first trigger member 500 and a first control valve 600. The first driving member 400 is transmission-connected to the first trigger member 500 and the detection member 300, so that the first trigger member 500 and the detection member 300 can synchronously move back and forth in the direction close to or away from the installation platform 100. The first control valve 600 is correspondingly arranged to the first trigger member 500. When the interference portion 320 interferes with the hinge 200, the first trigger member 500 and the first control valve 600 are spaced apart so as to be unable to trigger the first control valve 600. When the interference portion 320 cannot interfere with the hinge 200, the first trigger member 500 can continue to move toward the direction close to the installation platform 100 to trigger the first control valve 600. In this way, when the first trigger member 500 is used to trigger the first control valve 600, the first control valve 600 will generate a corresponding over-position signal, and when the first trigger member 500 cannot trigger the second control valve 900, the first control valve 600 will not generate a corresponding over-position signal, so that the operator can quickly determine whether the installed hinge 200 is correct.

[0081] Optionally, the first drive member 400 is configured as a first telescopic cylinder, and the first control valve 600 is used to connect the air source to the first telescopic cylinder, thereby controlling the corresponding connection or disconnection between the first telescopic cylinder and the air source. In this way, if the incorrect hinge 200 is installed, the air source cannot communicate with the first telescopic cylinder, preventing the detection member 300 from resetting and, consequently, preventing the vehicle model tooling from proceeding to the next step. This prevents damage or scrapping of the vehicle door due to the installation of a misplaced hinge 200, ensuring that the correct hinge 200 is installed. Furthermore, the vehicle model tooling cannot proceed to the next step, allowing the operator to promptly detect the incorrect hinge 200 installation and take appropriate measures.

[0082] Specifically in this embodiment, the first trigger member 500 is configured as a first trigger piece provided on the first telescopic cylinder, and the first control valve 600 is configured as a first air circuit valve provided corresponding to the first trigger piece. The first telescopic cylinder can be connected to the air source through the first air circuit valve. The first telescopic cylinder can drive the detection member 300 and the first trigger piece to move back and forth in the direction of approaching or moving away from the installation platform 100 to ensure that the plug-in portion 310 of the detection member 300 can be plugged into and matched with the positioning hole on the hinge 200.

[0083] like Figure 1 、 Figure 2 and Figure 3As shown, in one embodiment, the hinge error prevention mechanism 10 further includes a second driving member 700, a limiting assembly 800, a third driving member and a second control valve 900. The second driving member 700 is transmission-connected to the limiting assembly 800 and the third driving member, and the third driving member is transmission-connected to the detection member 300, so that the limiting assembly 800, the third driving member and the detection member 300 can synchronously move back and forth in the direction close to or away from the installation platform 100. The second control valve 900 is correspondingly arranged to the limiting assembly 800. When the limiting assembly 800 moves to the position that triggers the second control valve 900, the second driving member 700 stops driving the limiting assembly 800, the third driving member and the detection member 300 to move, and the limiting assembly 800 interferes with the hinge 200 to limit the position of the hinge 200 relative to the installation platform 100. The detection member 300 is correspondingly arranged to the positioning hole of the hinge 200. In this way, when the third control valve is triggered by the second trigger member, the third control valve will generate a corresponding over-position signal, and when the second trigger member cannot trigger the third control valve, the third control valve will not generate a corresponding over-position signal, so that the operator can quickly determine whether the installed hinge 200 is correct.

[0084] like Figure 1 、 Figure 2 and Figure 3 As shown, the second driving member 700 is further configured as a tilting cylinder. The hinge error prevention mechanism 10 also includes a second triggering member and a third control valve. The third driving member is in transmission connection with the second triggering member, allowing the second triggering member and the detection member 300 to synchronously move back and forth in a direction toward or away from the mounting platform 100. The third control valve is correspondingly provided with the second triggering member and is connected to the tilting cylinder to control the tilting cylinder to maintain or release pressure. In this way, when the hinge 200 is installed incorrectly, the tilting cylinder releases pressure through the third control valve, making it impossible for the limit assembly 800 to limit the position of the hinge 200 relative to the mounting platform 100. As a result, the vehicle body tooling is easily unable to proceed to the next step due to the movement of the hinge 200 relative to the mounting platform 100, thereby preventing the vehicle door from being damaged or scrapped due to the installation of the misplaced hinge 200 and ensuring that the vehicle door can be installed with the correct hinge 200.

[0085] Specifically in this embodiment, the second control valve 900 is configured as a second air circuit valve, and the flip cylinder can be connected to the air source through the second air circuit valve. The second trigger member is configured as a second trigger plate corresponding to the second air circuit valve. The flip cylinder is transmission-connected to the second trigger plate, so that the second trigger plate can be synchronously flipped with the detection member 300 in a direction close to or away from the mounting platform 100. When the first contact plate hits the second air circuit valve to trigger the second air circuit valve, the first clamping block 810, the second clamping block 820 and the positioning pin 830 are just flipped to a position where they are in contact with the hinge 200, and the second air circuit valve is switched from the on state to the closed state to stop charging the flip cylinder, so that the flip cylinder stops driving the first clamping block 810, the second clamping block 820 and the positioning pin 830 to flip. The first clamping block 810, the second clamping block 820 and the positioning pin 830 can all maintain contact with the hinge 200, thereby quickly and accurately limiting the position of the hinge 200 relative to the mounting platform 100.

[0086] Specifically, in this embodiment, the third control valve is configured as a pressure relief valve, and the tilting cylinder can communicate with the external environment through the pressure relief valve. Thus, when the hinge 200 is correctly installed, the pressure relief valve is closed, and the tilting cylinder maintains pressure, ensuring that the limit assembly 800 can interfere with the hinge 200 to limit the position of the hinge 200 relative to the mounting platform 100. When the hinge 200 is incorrectly installed, the pressure relief valve is opened, and the tilting cylinder is deflated, releasing the interference between the limit assembly 800 and the hinge 200, thereby achieving the effect that the limit assembly 800 cannot limit the position of the hinge 200 relative to the mounting platform 100.
