Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of decorative strip production device, more particularly to a length detection device for decorative strip. BACKGROUND

[0002] Automotive trim refers to the strip-shaped components installed on the exterior or interior of a vehicle for decoration, protection of the vehicle body, or enhancement of the vehicle's aesthetic appeal. They are typically made of materials such as metal (e.g., stainless steel, aluminum alloy), plastic, or rubber, and have different designs and purposes depending on their location and function.

[0003] In current automotive manufacturing processes, robotic arms are used to grasp and transfer automotive trims to the next process for cutting to length. However, several challenges have been encountered. First, when using robotic arms to grasp automotive trims, due to the limitations of existing technology, the robotic arm grasping position often deviates. This deviation causes the trim to be unable to be accurately placed in the positioning structure of the next process, thereby affecting the quality and efficiency of subsequent processing steps. Specifically, due to improper selection of the robotic arm grasping point or uneven grasping force, the trim cannot be accurately aligned with the target position, which not only reduces production efficiency but also may increase the rate of defective products.

[0004] Secondly, when cutting to length for trims with spatial structures, existing technology also faces difficulties. Trims often have complex three-dimensional shapes, which require precise control of the cutting length on both sides during the cutting process. However, existing automated equipment and technology cannot achieve this goal because they cannot effectively identify and adjust the specific cutting length for both ends of the trim. Especially when facing different models, sizes, and design styles of trims, determining the precise cutting point for each end becomes more complex. The existence of these problems significantly limits the degree of automation of the production line and the overall efficiency, while increasing the need for manual intervention, further affecting the continuity and stability of production.

DETAILED DESCRIPTION

[0031] The technical solutions of the present application will be further described in combination with the drawings and specific embodiments of the present application, but the present application is not limited to these embodiments.

[0032] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications will also change accordingly.

[0033] As shown in the drawings, the length detection device for the decorative strip of the present application comprises a positioning member 100, a fixing assembly 200 and a measuring member 300. Figures 1 to 4

[0034] The positioning member 100 is used to receive and position the decorative strip 500 to be detected, and the fixing assembly 200 is used to fix the decorative strip 500 after it is placed on the positioning member 100. The measuring member 300 is arranged on the side of the positioning member 100 at both ends of the decorative strip 500. The measuring member 300 can detect the length and position deviation of the decorative strip 500 after the decorative strip 500 is placed on the positioning member 100 and fixed by the fixing assembly 200.

[0035] Before the decorative strip 500 is clamped to the positioning member 100, a certain cutting allowance is reserved at both ends of the decorative strip 500. During operation, the robot hand grabs the decorative strip 500 and places it on the positioning member 100, and then the fixing assembly 200 fixes the decorative strip 500. Under normal circumstances, after the decorative strip 500 is placed on the positioning member 100, the measuring members 300 at both ends will display the value of the allowance under the push of the decorative strip 500, and the measured values of the allowance on both sides should be consistent (for example, 0.5 mm). Then, the fixing assembly 200 releases the fixation of the decorative strip 500, and the robot hand carries the decorative strip 500 to the next cutting process.

[0036] However, when the position of the robot hand grabbing the decorative strip 500 deviates, the values displayed on the measuring members 300 will also differ (for example, the left measuring member 300 displays 0.4 mm, and the right one displays 0.6 mm). By feeding back the values displayed on the measuring members 300 to the control system, the robot hand can adjust the position of grabbing the decorative strip 500 according to the final measured values, thereby assisting the robot hand to correct. In addition, the values displayed on the measuring members 300 can also be transmitted to the next cutting process, so as to determine the final cutting length of the decorative strip 500 at both ends according to the values.

[0037] ​In the scheme, the decoration strip 500 to be detected is positioned by the positioning member 100, and the decoration strip 500 is fixed on the positioning member 100 by using the fixing assembly 200, so as to ensure that the decoration strip 500 remains stable during the detection process. Finally, the excess amount at both ends of the decoration strip 500 and the deviation amount on the left and right sides are measured by the measuring member 300 at both ends of the decoration strip 500. This process not only improves the automation degree and overall efficiency of the production line, but also reduces the need for manual intervention, further improving the continuity and stability of production.

[0038] The scheme also includes a support table 400, and the positioning member 100 is arranged on the support table 400. The projection of the positioning member 100 on the support table 400 is in an arc-shaped structure, so as to simulate the installation state of the decoration strip 500 on the vehicle.

[0039] The support table 400 is configured as a support component of the entire detection device, so as to provide support for the positioning member 100. The fixing assembly 200 and the measuring member 300 can be arranged on the support table 400. The connection mode between the positioning member 100 and the support table 400 can be a detachable mode such as threaded connection or clamping, or a fixed connection mode such as gluing or welding.

[0040] During the processing of the decoration strip 500, due to the deformation of the material, the shape processed out may be different from the shape finally installed on the vehicle. If only the processed shape is measured to confirm the cutting allowance, the size of the decoration strip 500 may deviate when actually installed on the vehicle. In order to improve the cutting precision, the projection of the positioning member 100 on the support table 400 is designed in an arc-shaped structure, so as to simulate the state of the decoration strip 500 after being installed on the vehicle. Then, the processing allowance of the decoration strip 500 is measured in this state, so as to ensure that the decoration strip 500 can reach the required size precision when finally installed.

[0041] In the scheme, the support table 400 has a length direction L, a width direction W and a height direction H, and the positioning member 100 includes a first positioning block 110, a second positioning block 120 and a third positioning block 130. The first positioning block 110, the second positioning block 120 and the third positioning block 130 are all used for positioning the decoration strip 500.

[0042] Further, along the height direction H, the length of the second positioning block 120 is greater than that of the first positioning block 110 and the third positioning block 130, so as to make the decoration strip 500 present an arc shape in the plane formed by the length direction L and the height direction H, so as to make the state of the decoration strip 500 during measurement more consistent with the state during installation on the vehicle.

[0043] Preferably, the number of the second positioning block 120 is two or more.

[0044] In the present scheme, the support table 400 comprises a base 410, a support beam 420 arranged on the base 410, and a connecting block 430 arranged on the support beam 420 and corresponding to the first positioning block 110, the second positioning block 120 and the third positioning block 130 one by one. A connecting rod 440, one end of which passes through the support beam 420 and the base 410 in turn and is exposed outside the base 410.

[0045] The connecting rod 440 is designed as a component connecting the support beam 420 and the base 410 on the one hand, and its partial area extends out of the base 410 on the other hand, so as to facilitate the connection of the detection device and other structures in the present scheme. In a preferred embodiment, the connecting rod 440 is equipped with an external thread which matches a threaded sleeve on the base 410, thereby realizing the threaded connection between the connecting rod 440 and the base 410. A pressing part is arranged near the end of the connecting rod 440 close to the support beam 420 for easy operation. In this way, the connecting rod 440 not only stably connects the base 410 and the support beam 420, but also provides convenience for the installation of additional detection equipment or other structures.

[0046] In order to realize the positioning of the decorative strip 500 by the positioning member 100, the top of each of the first positioning block 110, the second positioning block 120 and the third positioning block 130 is provided with a positioning groove 140 which is adapted to the shape of the decorative strip 500.

[0047] Specifically, the gap between the width of the positioning groove 140 and the width of the decorative strip 500 is set to be 0.02-0.08 mm. A protruding structure is further arranged in the positioning groove 140, which will be embedded in the concave structure inside the decorative strip 500 after the decorative strip 500 is placed on the positioning member 100. The gap between the protruding structure and the concave structure of the decorative strip 500 is also kept within the range of 0.02-0.08 mm.

[0048] In the present scheme, the fixing assembly 200 comprises a driving member 210 and a pressing block 220 connected to the output end of the driving member 210, which is used to press on the surface of the decorative strip 500.

[0049] The driving member 210 can be a power device such as a motor or a pneumatic cylinder, which is mainly used to drive the pressing block 220 to act so as to realize the compression and relaxation of the decorative strip 500. For example, before the decorative strip 500 is placed in the positioning member 100, the driving member 210 drives the pressing block 220 to rotate, so that the positioning groove 140 is exposed to the outside, so that the decorative strip 500 can smoothly enter the positioning groove 140. After the decorative strip 500 is placed on the positioning member 100, the driving member 210 drives the pressing block 220 to reset and press on the decorative strip 500, thereby completing the fixation of the decorative strip 500.

[0050] Preferably, the end surface of the pressing block 220 in contact with the trim strip 500 is provided with a profiling surface 221 which is adapted to the profile of the trim strip 500, for increasing the contact area between the pressing block 220 and the trim strip 500, and for more stably fixing the trim strip 500 on the positioning member 100.

[0051] In the present solution, the measuring member 300 comprises a body 310 for measuring the distance of the measuring rod 320 retracted into it, and a measuring rod 320 retractably arranged in the body 310, the measuring rod 320 can be retracted into the body 310 under the pushing of the trim strip 500, preferably, the measuring member 300 is an electronic measuring machine, which is internally provided with optical instruments for measuring the retraction distance of the measuring rod 320, and is also equipped with an electronic board for processing the detection data.
