[0002] Sometimes one or more metal steel strips are embedded in the automotive sealing strip to increase the structural stability of the sealing strip and prevent excessive stretching or compression deformation during frequent opening and closing of the door. The presence of the steel strip enables the sealing strip to maintain good flexibility to adapt to sealing surfaces of various shapes while having sufficient strength to maintain its functionality and lifespan.

[0003] However, after rolling or heat treatment, the steel strip is affected by internal stress, and the product thickness and width will exceed the standard during the deep processing of the steel strip, that is, the size of the steel strip will change, affecting the later use of the product, wasting a lot of materials and increasing costs. Since the operator cannot discover the excessive steel strip in time, the qualified rate of the steel strip product is seriously affected, increasing the production cost. Utility Model Content

[0004] In view of this, the utility model provides a size detection device for the production of automobile sealing strip skeletons, aiming to solve the problem in the prior art that operators are unable to promptly detect that the steel strip exceeds the standard.

[0013] A first spring, arranged in the limiting channel, with a first end thereof abutting against a second side of the limiting channel;

[0014] A steel ball is arranged in the limiting channel and abuts against the second end of the first spring. The steel ball can extend into the corresponding limiting groove under the action of the first spring.

[0015] A further improvement of the utility model is that a first screw rod is threadedly connected to the second side of the limiting channel, and one end of the first screw rod abuts against the first end of the first spring.

[0016] A further improvement of the utility model is that a tensioning mechanism is also arranged on the main bracket between the two guide rollers for tensioning the traveling steel belt.

DETAILED DESCRIPTION

[0036] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, in the following description, specific details such as specific system structures and technologies are proposed for the purpose of explanation rather than limitation, so as to thoroughly understand the embodiments of the utility model. However, it should be clear to those skilled in the art that the utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from hindering the description of the utility model.

[0037] The utility model provides a size detection device for automobile sealing strip frame production, according to the attached manual Figure 1 To Attachment Figure 6 It can be seen that it includes: a main bracket 10, a mounting seat 13, a size detection module 20, a connecting assembly 30, and a sensor 40. Two rotatable guide rollers 11 are respectively arranged on the front and rear sides of the main bracket 10, and a meter 12 is arranged on the main bracket 10 above each guide roller 11; the mounting seat 13 is arranged on the rear side of the main bracket 10, and a mounting groove 14 is arranged on it; the size detection module 20 is arranged in the mounting groove 14, and a feed port 201 and a discharge port 202 are respectively arranged on the front and rear of the main bracket 10, and the feed port 201 is larger than the size of the steel strip, and the discharge port 202 is equal to the size of the steel strip; the connecting assembly 30 is arranged on the mounting seat 13, and is connected to the size detection module 20, and the size detection module 20 can be separated from the mounting groove 14 under the action of external force; the sensor 40 is arranged on the mounting seat 13 below the size detection module 20, and is connected to the alarm device 41 on the main bracket 10, and when the sensor 40 detects that the size detection module 20 is separated from the mounting groove 14, the alarm device 41 can be controlled to sound.

[0038] An unwinding device and a reeling device are respectively provided at both ends of the steel strip. The unwinding device unwinds the steel strip while the reeling device reels it. At this time, the steel strip will pass through the two guide rollers 11 in sequence during the movement, and then pass through the size detection module 20 again. When the size of the steel strip exceeds the standard, it will be stuck in the size detection module 20. At this time, if the reeling device drives the steel strip to continue to move forward, the reeling force of the reeling device will drive the detection block to separate from the mounting groove 14. Then, when the sensor 40 detects that the size detection module 20 is separated from the mounting groove 14, the alarm device 41 can be controlled to sound. After hearing the alarm, the operator can detect that the size of the steel strip exceeds the standard, which can effectively and conveniently detect that the steel strip exceeds the standard in time, so that the operator can deal with it in time, greatly improving the product qualification rate, reducing waste and reducing costs.

[0039] The connecting assembly 30 on the mounting seat 13 can effectively connect the size detection module 20 with the mounting groove 14 to prevent the size detection module 20 from being separated from the mounting groove 14 when the steel belt moves normally in the size detection module 20, thereby effectively ensuring the detection effect.

[0040] As an embodiment, according to the attached Figure 3 It can be seen that the connection assembly 30 includes: a limiting channel 31 is horizontally arranged on the mounting seat 13, and its first side is connected to the mounting groove 14, and a limiting groove 32 corresponding to the limiting channel 31 is arranged on the size detection module 20; a first spring 33 is arranged in the limiting channel 31, and its first end abuts against the second side of the limiting channel 31; a steel ball 34 is arranged in the limiting channel 31 and abuts against the second end of the first spring 33, and the steel ball 34 can extend into the corresponding limiting groove 32 under the action of the first spring 33. The second side of the limiting channel 31 is threadedly connected with a first screw rod 35, and one end of the first screw rod 35 abuts against the first end of the first spring 33.

[0041] Through the cooperation of the first spring 33 and the steel ball 34, a dynamic and adjustable positioning mechanism is provided for the size detection module 20. When the size detection module 20 is inserted into the mounting groove 14, the steel ball 34 will enter the limit groove 32 on the module under the elastic force of the first spring 33, thereby achieving a stable connection. In addition, through the buffering effect of the first spring 33 and the steel ball 34, the size detection module 20 can be urgently separated from the mounting groove 14 under the action of the winding force, thereby reducing the damage to the size detection module 20 and the mounting seat 13 caused by direct hard impact, thereby protecting the components.

[0042] The threaded connection of the first screw 35 allows for fine adjustment of the spring pressure, which means that the installation tightness of the size detection module 20 can be controlled very accurately, ensuring that the appropriate tension and position stability can be maintained under any working conditions, thereby improving the control accuracy and working efficiency of the overall system. And this design can adjust the compression amount of the first spring 33 as needed to adjust the tightness and holding force of the docking, adapt to different working conditions, and ensure the reliability and stability of the connection.

[0043] In this embodiment, according to the specification Figure 4 It can be seen that a tensioning mechanism 50 is also provided on the main support 10 between the two guide rollers 11, which is used to tension the steel belt in motion. A tensioning mechanism 50 is also provided on the main support 10 between the two guide rollers 11, which can keep the steel belt in motion at an appropriate tension, avoid measurement errors caused by relaxation, and through tensioning, reduce fluctuations and jitters of the steel belt during transmission, so that the steel belt passes through the size detection module 20 straight and stably, and avoid potential safety hazards such as winding and breaking caused by loose steel belt.

[0044] In this embodiment, according to the specification Figure 4 To Attachment Figure 5 It can be seen that the tensioning mechanism 50 includes: a first guide groove 51 is vertically arranged on the main bracket 10 between the two guide rollers 11, and a first guide rod 52 parallel to the first guide groove 51 is arranged on the main bracket 10; a connecting shaft 54 ​​arranged on the connecting seat 53 passes through the first guide groove 51, and a tensioning wheel 55 is arranged, the connecting seat 53 is connected to the sliding seat 56 on the first guide rod 52, and a fixed pulley 57 is arranged on the main bracket 10 above the connecting seat 53; the first end of the rope 58 is connected to the connecting seat 53, and the second end is wound around the set pulley 57, and a counterweight block 59 is arranged.

[0045] The tensioning wheel 55 is rotationally connected to the connecting shaft 54, and the connecting shaft 54 ​​is slidingly connected to and penetrates the first guide groove 51. Since the tensioning wheel 55 is arranged on the connecting seat 53, and the tensioning wheel 55 and the connecting seat 53 move downward under the action of their own gravity, since the connecting block is connected to the counterweight block 59 through the rope 58 and the fixed pulley 57, the counterweight block 59 and the tensioning wheel 55 reach a state of dynamic balance. When the unwinding speed of the unwinding device is too fast, the length of the steel belt between the two guide rollers 11 will be longer. At this time, the tensioning wheel 55 moves downward and the counterweight block 59 moves upward to tension the steel belt in turn. On the contrary, when the unwinding device is too slow, it will drive the tensioning wheel 55 to move upward, and always keep the steel belt in a tensioned state. The structure is simple and the tensioning effect is good.

[0046] Rope 58 is a steel wire rope, which has extremely high strength and load-bearing capacity, can withstand large tension without breaking easily, and is more wear-resistant, can resist the wear that may occur during repeated tensioning and releasing, extend service life, reduce maintenance and replacement frequency, and reduce operating costs.

[0047] In this embodiment, according to the specification Figure 4 It can be seen that a second spring 60 is provided on the first guide rod 52 below the sliding seat 56. The second spring 60 can effectively protect the sliding seat 56 slidably connected to the first guide rod 52, prevent the sliding seat 56 from directly colliding with the main bracket 10 at the lower end of the first guide rod 52 under the deadweight of the connecting seat 53, and extend the service life of the sliding seat 56.

[0048] In this embodiment, according to the specification Figure 4 It can be seen that a tension positioner 61 is also provided in the main support 10, and the first end of the pull rod 62 is connected to the first slider on the tension positioner 61, and the second end is connected to the sliding seat 56. When the sliding seat 56 is raised or lowered, the first slider is driven to change position on the tension positioner 61 through the pull rod 62, and the resistance of the tension positioner 61 changes at this time. The tension positioner 61 is connected to the unwinding device, and then the unwinding speed is controlled to slow down or speed up, thereby ensuring that the steel belt is always in a tensioned state.
