[0025] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in

[0027] It can be understood that the pre-bending tooling for the skeleton 4 further includes a driving member, which is communicatively connected to the controller. The controller controls the skeleton 4 to slide in the receiving groove 2 at a uniform speed or an accelerated speed. The detection assembly 3 has a detection area, which is opposite to the wing area of the skeleton 4. The skeleton 4 passes through this detection area, so that the detection assembly 3 obtains the first height parameter of the skeleton 4 from the assembly, and detects the second height parameter from the receiving groove 2 to the detection assembly 3 through the gap between the two wings. When the skeleton 4 has only one wing, the projection of the detection range is projected onto the wing area.

[0028] When the skeleton 4 has two wings, the wings include a first wing 41 and a second wing 42. The length of the first wing 41 is longer than that of the second wing 42, and the difference is X. That is to say, the first gap 411 is longer than the second gap 421, and the difference is also X. The detection area is a square area with a width of X, and this detection area is close to the first wing 41. One side of the vertical projection of the detection area coincides with the bone body, and the other side covers the first wing 41, so that the detection assembly 3 obtains the first height parameter of the skeleton 4 from the assembly, and detects the second height parameter from the receiving groove 2 to the detection assembly 3 through the gap between the two wings.

[0029] It should be noted that when wings are provided on both sides of the skeleton 4 and the lengths of the first wing 41 and the second wing 42 are equal, at this time, the widths of the first gap 411 and the second gap 421 are not equal, so as to form an asymmetric skeleton 4. At this time, the detection assembly 3 detects the width of the first gap 411 and / or the gap width to obtain the gap width parameter;

[0030] When the widths of the first gap 411 and the second gap 421 are equal, the widths of the first wing 41 and the second wing 42 are not equal to form an asymmetric skeleton 4. At this time, the detection assembly 3 detects the width of the first wing 41 and / or the width of the second wing 42 to obtain the wing width parameter.

[0031] Specifically, the skeleton 4 is placed in the receiving groove 2 and slides along the length direction of the receiving groove 2. The detection assembly 3 is arranged above the receiving groove 2. The detection assembly 3 detects the first height parameter, the second height parameter, the gap width parameter or the wing width parameter of the skeleton 4 and feeds it back to the controller. The controller compares it with the judgment threshold, so as to judge the placement direction of the skeleton 4, so as to ensure that the skeleton 4 is placed correctly during the pre-bending process, avoid the installation failure of the seal prepared from the pre-bent skeleton 4, improve the yield rate, and reduce the production cost.

[0032] In some embodiments of the present utility model, the detection component 3 includes: a housing box 31 and a distance sensor 32; fixedly arranged on the bracket 1; the distance sensor 32 is arranged in the housing box 31, a hollow groove 312 is provided at the bottom of the housing box 31, and the distance sensor 32 is adapted to project sensing light vertically downward through the hollow groove 312, and the projection spot of the sensing light is smaller than the gap width.

[0033] Specifically, a hollow groove 312 is provided at the bottom of the housing box 31 so that the distance sensor 32 projects sensing light downward, and the projection spot formed by the projected sensing light is smaller than the gap width, so as to ensure that the projected light can pass through the gap to detect the second height parameter from the accommodation groove 2 to the detection component 3.

[0034] In some embodiments of the present utility model, a in-place sensor 33 and a first alarm device are arranged in the housing box 31. The in-place sensor 33 is adapted to detect the installation in-place parameter of the distance sensor 32. The in-place sensor 33 is communicatively connected to the controller, and the controller is adapted to receive the installation in-place parameter in real time and control the start and stop of the first alarm device.

[0035] Specifically, the detection component 3 needs to be positioned and installed in the housing box 31 so that the detection area faces the skeleton 4, thereby ensuring the accuracy of detection. By arranging the in-place sensor 33 in the housing box 31, the in-place sensor 33 is communicatively connected to the controller, so as to detect the installation in-place parameter of the distance sensor 32 and feedback it to the controller. The controller is communicatively connected to the first alarm device. When the controller receives the installation in-place parameter, it controls the first alarm device to emit a warning light or warning sound indicating successful installation. If the controller does not receive the installation in-place parameter of the first alarm, the first alarm device remains in the off state.

[0036] In some embodiments of the present utility model, a guiding groove 311 is provided on the side wall of the housing box 31, and the distance sensor 32 is provided with a limiting post 321. The guiding groove 311 and the limiting post 321 cooperate with each other to position and install the distance sensor 32 in the housing box 31.

[0037] Specifically, by providing the guiding groove 311 on the side wall of the housing box 31 and the distance sensor 32 is provided with the limiting post 321. During the installation process, the limiting post 321 slides along the length direction of the guiding groove 311. The guiding groove 311 and the limiting post 321 cooperate with each other, so that the distance sensor 32 is installed in the housing box 31 in a limited direction, so as to ensure that the detection area faces the area to be detected of the skeleton 4.

[0038] In some embodiments of the present utility model, the bracket 1 is provided with a waist-shaped groove 11. The detection assembly 3 further includes a fastener 34. The length direction of the waist-shaped groove 11 is arranged horizontally. The fastener 34 passes through the waist-shaped groove 11 to fixedly connect the accommodation box 31 and the bracket 1. The fastener 34 can slide along the length direction of the waist-shaped groove 11 to adjust the horizontal installation position of the detection assembly 3.

[0039] Specifically, by sliding the fastener 34, the horizontal installation position of the detection assembly 3 is adjusted so that the detection area is opposite to the area to be detected of the skeleton 4, improving the detection accuracy and universality.

[0040] In some embodiments of the present utility model, the pre-bending tooling for the skeleton 4 further includes a second alarm device. The second alarm device is communicatively connected to the controller. The placement directions of the skeleton 4 include forward placement and reverse placement.

[0041] When the controller determines that the skeleton 4 is in forward placement, the controller controls the second alarm device to be in the off state; when the controller determines that the skeleton 4 is in reverse placement, the controller controls the second alarm device to be in the activated state.

[0042] Specifically, the controller controls the activation and deactivation of the second alarm device according to the placement direction information of the skeleton 4. When the controller determines that the skeleton 4 is in forward placement, the second alarm device is in the off state. When the controller controls the skeleton 4 to be in reverse placement, the alarm device is in the activated state, thereby warning the operator to re-place the skeleton 4 to ensure the smooth progress of the pre-bending operation of the skeleton 4, improving the qualified product rate and reducing the cost.

[0043] A method for identifying the placement direction of the skeleton 4 is applicable to an asymmetric skeleton 4. The skeleton 4 has a bone body in a joint shape and wing pieces extending horizontally outward at the bone body. There is a gap between adjacent two wing pieces. The wing pieces are only provided on one side of the bone body. The method includes the following steps:

[0044] The controller drives the skeleton 4 to slide along the length direction of the accommodation groove 2.

[0045] The detection assembly 3 detects a first height parameter of the detection assembly 3 from the skeleton 4 and a second height parameter of the detection assembly 3 from the bottom of the accommodation groove 2.

[0046] When the controller receives alternately changing first height parameters and second height parameters, the controller determines that the skeleton 4 is in forward placement; when the controller only receives the first height parameter, the controller determines that the skeleton 4 is in reverse placement; when the controller only receives the second height parameter, the controller determines that no skeleton 4 is placed in the accommodation groove 2.

[0047] Specifically, this recognition method is applicable to the asymmetric skeleton 4. When the winglets are arranged on one side of the bone body, the detection component 3 detects the first height parameter of the distance between the skeleton 4 and the detection component 3 and the second height parameter from the detection accommodation groove 2 to the detection component 3. When the controller receives the alternately changing first height parameter and second height parameter, the controller determines that the skeleton 4 is placed correctly. When the controller only receives the first height parameter, it determines that the skeleton 4 is placed reversely. When the controller only receives the second height parameter, the controller determines that no skeleton 4 is placed in the accommodation groove 2. Through this recognition method, the placement direction of the skeleton 4 can be effectively detected, so as to ensure that the skeleton 4 is placed correctly during the pre-bending process, avoid the installation failure of the seal produced by the pre-bent skeleton 4, thereby improving the yield rate and reducing the production cost.

[0048] When winglets are arranged on both sides of the skeleton 4, the winglets include a first winglet 41 and a second winglet 42. The length of the first winglet 41 is longer than that of the second winglet 42. Therefore, the difference area where the first winglet 41 is longer than the second winglet 42 is defined as the area to be detected. The projection of the detection area of the detection component 3 coincides with the area to be detected, so as to be suitable for detecting the first height parameter and the second height parameter. At this time, when the controller receives the alternately changing first height parameter and second height parameter, the controller determines that the skeleton 4 is placed correctly. When the controller only receives the first height parameter, it determines that the skeleton 4 is placed reversely. When the controller only receives the second height parameter, the controller determines that no skeleton 4 is placed in the accommodation groove 2.

[0049] The present utility model also provides a method for recognizing the placement direction of the skeleton 4, which is applicable to the asymmetric skeleton 4. The skeleton 4 has a bone body in a bone joint shape and winglets extending horizontally along the bone body. The winglets include a plurality of first winglets 41 and / or a plurality of second winglets 42 respectively located on both sides of the bone body. There is a first gap 411 between adjacent first winglets 41, and a second gap 421 between adjacent second winglets 42. The method includes the following steps:

[0050] When the width of the first gap 411 is greater than the width of the second gap 421;

[0051] The controller drives the skeleton 4 to slide along the length direction of the accommodation groove 2;

[0052] The detection component 3 detects the first gap parameter and / or the second gap parameter of the gaps between the winglets on both sides of the skeleton 4 in real time;

[0053] Set a gap judgment threshold. The controller receives the first gap parameter and / or the second gap parameter, and compares the gap judgment threshold with the first gap parameter and / or the second gap parameter to judge the placement direction of the skeleton 4; or

[0054] When the width of the first winglet 41 is greater than the width of the second winglet 42;

[0055] The controller drives the skeleton 4 to slide along the length direction of the accommodating groove 2;

[0056] The detection component 3 detects the first width parameter and / or the second width parameter of the wing pieces on both sides of the skeleton 4 in real time;

[0057] A width judgment threshold is set. The controller receives the first width parameter and / or the second width parameter, and compares the width judgment threshold with the first width parameter and / or the second width parameter to judge the placement direction of the skeleton 4.

[0058] Specifically, the wing pieces include a first wing piece 41 and a second wing piece 42, and the first wing piece 41 and the second wing piece 42 are respectively arranged on both sides of the bone body. When the first gap 411 between the first wing pieces 41 is not equal to the second gap 421 between the second wing pieces 42 or the width of the first wing piece 41 is not equal to the width of the second wing piece 42, an asymmetric skeleton 4 is formed. At this time, the detection component 3 detects the first gap parameter and the second gap parameter, and compares the first gap parameter and the second gap parameter with the gap judgment threshold to judge the placement direction of the skeleton 4. When the first gap 411 and the second gap 421 are equal and the width of the first wing piece 41 is not equal to the width of the second wing piece 42, the detection component 3 detects the first width parameter and the second width parameter and compares them with the width judgment threshold to judge the placement direction of the skeleton 4. This recognition method can be applied to the asymmetric skeleton 4 with bilateral wing pieces. By judging the placement direction of the skeleton 4, it is ensured that the skeleton 4 is correctly placed during the pre-bending process, avoiding the installation failure of the seal prepared from the pre-bent skeleton 4, thereby improving the yield rate and reducing the production cost.

[0059] In some embodiments of the present invention, the detection component 3 includes a first sensing member and a second sensing member. The first sensing member detects the first gap parameter, and the second sensing member detects the second gap parameter;

[0060] The gap judgment threshold is less than the first gap 411 and greater than the second gap 421;

[0061] When the first gap parameter is greater than the gap judgment threshold and / or the second gap parameter is less than the gap judgment threshold, the controller judges that the skeleton 4 is placed in the forward direction;

[0062] When the first gap parameter is less than the gap judgment threshold and / or the second gap parameter is greater than the gap judgment threshold, the controller judges that the skeleton 4 is placed in the reverse direction.

[0063] In some embodiments of the present invention, the detection component 3 includes a first sensing member and a second sensing member. The first sensing member detects the first width parameter, and the second sensing member is adapted to detect the second width parameter;

[0064] The width judgment threshold is less than the width of the first wing piece 41 and greater than the width of the second wing piece 42;

[0065] When the first width parameter is greater than the width judgment threshold value and / or the second width parameter is less than the width judgment threshold value, the controller determines that the framework 4 is placed in the forward direction;

[0066] When the first width parameter is less than the width judgment threshold value and / or the second width parameter is greater than the width judgment threshold value, the controller determines that the framework 4 is placed in the reverse direction.

[0067] Obviously, the above embodiments are only examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the creation of the present utility model.
