[0031] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0032] It is easy to understand that according to the technical solution of the present invention, a variety of structural modes and implementation modes can be replaced with each other by those skilled in the art without changing the essential spirit of the present invention. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the invention.

[0033] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to the structure shown in the drawings. They are relative concepts and may vary depending on the location and usage of the device. Therefore, these or other directional terms should not be interpreted as restrictive.

[0034] like Figure 1-3 The figure shows a jam detection device 10 provided by the present invention, which includes a transmission mechanism 1 and a detection mechanism 2. The transmission mechanism 1 includes a transmission component 11 that can be driven by the part to be detected. The detection mechanism 2 includes a detector 21 for detecting jams. The detector 21 determines whether the part to be detected is jammed by measuring the activity data of the transmission component 11.

[0035] The jam detection device 10 can detect jams in a component to be inspected, which can rotate. During a jam detection, the component to be inspected contacts the transmission component 11, causing the transmission component 11 to move. The detector 21 then measures the movement data of the transmission component 11 and analyzes the data to determine if a jam has occurred. The contact between the component to be inspected and the transmission component 11 can be direct or through an intermediary.

[0036] Specifically, the jam detection device 10 of this embodiment is used in a production line of a paint shop as an example for description. The part to be detected is the trolley straightening wheel 40 , and the jam detection device 10 detects the jam of the trolley straightening wheel 40 .

[0037] The jam detection device 10 includes a transmission mechanism 1 and a detection mechanism 2, which is connected to the transmission mechanism 1. The transmission mechanism 1 includes a transmission component 11, which is driven to move upon contact with the trolley straightening wheels 40. The detection mechanism 2 includes a detector 21, whose detection end is connected to the transmission component 11. The detection mechanism 21 detects the jam condition of the trolley straightening wheels 40 by measuring the movement of the transmission component 11. For example, the detection mechanism 2 detects the movement frequency or movement distance of the transmission component 11.

[0038] When the jam detection device 10 is in use, the transmission mechanism 1 and the detection mechanism 2 are installed on a production line or a test bench. When the trolley 20 passes through the jam detection device 10, the trolley straightening wheels 40 come into contact with the transmission component 11.

[0039] This jam detection device 10 eliminates the need for regular manual inspections. Workers can now determine whether the trolley's straightening wheels 40 are jammed simply by observing the detector 21. This facilitates inspection, reduces manual labor, and frees up labor. Furthermore, the data detected by the detector 21 is more accurate, resulting in higher quality inspections.

[0040] In one embodiment, Figure 1 As shown, the detection mechanism 2 further includes a damping adjuster 22 , which is connected to the transmission component 11 .

[0041] The damping adjuster 22 is connected to the transmission component 11 to increase resistance to the movement of the transmission component 11, thereby being able to detect the blocking condition of the trolley straightening wheel 40 under different working conditions.

[0042] In one embodiment, Figure 1-2 As shown, the transmission mechanism 1 further includes a mechanism support 12, and the transmission component 11 includes a first transmission member 111, a second transmission member 112, and a transmission belt 113. At least one of the first transmission member 111 and the second transmission member 112 is rotatable. The first transmission member 111 and the second transmission member 112 are connected to the mechanism support 12. One end of the transmission belt 113 is looped over the first transmission member 111, and the other end is looped over the second transmission member 112. The detector 21 is used to detect the rotation of the rotatable transmission member of the first transmission member 111 and the second transmission member 112, or to detect the movement of the transmission belt 113.

[0043] Specifically, the transmission mechanism 1 includes a mechanism support 12, on which the transmission component 11 is mounted. The transmission component 11 consists of a first transmission member 111, a second transmission member 112, and a transmission belt 113. The first transmission member 111 and the second transmission member 112 are spaced apart on the mechanism support 12, and one or both of the first transmission member 111 and the second transmission member 112 are rotatably connected to the mechanism support 12. One end of the transmission belt 113 is looped over the first transmission member 111, and the other end is looped over the second transmission member 112. The detector 21 is connected to the first transmission member 111, the second transmission member 112, or the transmission belt 113.

[0044] For the sake of convenience, the transmission member connected to the detector 21 is defined as the first transmission member 111 below. The detector 21 is an incremental encoder. When the jam detection device 10 detects, the trolley straightening wheel 40 contacts the transmission belt 113 and generates friction. The trolley straightening wheel 40 drives the transmission belt 113 to move, and the movement of the transmission belt 113 drives the first transmission member 111 and the second transmission member 112 to rotate. The incremental encoder then outputs pulses by detecting the rotation of the first transmission member 111. When the friction between the trolley straightening wheel 40 and the transmission belt 113 is small, the number of pulses output by the incremental encoder is small; when the friction between the trolley straightening wheel 40 and the transmission belt 113 is large, the number of pulses output by the incremental encoder is large. The jam condition of the trolley straightening wheel 40 is determined by the number of pulses. If the number of pulses exceeds the preset value, the incremental encoder will issue an alarm.

[0045] If the trolley straightening wheel 40 is not stuck, rolling friction is generated between the trolley straightening wheel 40 and the transmission belt 113. The value of the rolling friction will not exceed the value set by the damping adjuster 22. At this time, the transmission belt 113 will not move, that is, the first transmission member 111 and the second transmission member 112 will not rotate, and the detector 21 will not detect any data.

[0046] Furthermore, in other embodiments, if the trolley straightening wheels 40 are not stuck, rolling friction is generated between the trolley straightening wheels 40 and the transmission belt 113. The damping force of the damping adjuster 22 can also be adjusted so that the rolling friction exceeds the value set by the damping adjuster 22, causing the transmission belt 113 to move. However, due to the limited magnitude of the rolling friction, the movement of the transmission belt 113 when not stuck will be significantly different from the movement of the transmission belt 113 when stuck. The detector 21 can also determine whether a jam has occurred by detecting the movement of the transmission belt 113.

[0047] If the trolley straightening wheel 40 becomes stuck, sliding friction is generated between the trolley straightening wheel 40 and the transmission belt 113. If the sliding friction exceeds the value set by the damping adjuster 22, the transmission 113 will move, driving the first transmission member 111 and the second transmission member 112 to rotate, and the detector 21 will detect data.

[0048] During the entire detection process, the trolley straightening wheel 40 will not usually get stuck throughout the entire process, but will intermittently drive the first transmission member 111, the second transmission member 112, and the transmission belt 113 to move, thereby causing the detector 21 to detect a period of pulse data. The more severe the jamming of the trolley straightening wheel 40, the more pulses it will generate during the detection process. In this way, the jamming situation can be determined by the number of pulses generated.

[0049] Optionally, the first transmission member 111 includes a first roller and a first rotating wheel, the first roller is rotatably connected to the mechanism bracket 12, the first rotating wheel is connected to the first roller, and the detector 21 is connected to the first roller. The second transmission member 112 includes a second roller and a second rotating wheel, the second roller is fixedly connected to the mechanism bracket 12, and the second rotating wheel is rotatably connected to the second roller via a bearing. When the trolley straightening wheel 40 contacts the transmission belt 113, the transmission belt 113 drives the first rotating wheel and the second rotating wheel to rotate, and the first rotating wheel is connected to the first roller via a key, driving the first roller to rotate, so that the detector 21 can detect the rotation of the first roller.

[0050] Optionally, the damping adjuster 22 is a magnetic damper connected to the first transmission member 111 to increase the resistance to the rotation of the first transmission member 111 .

[0051] Optionally, the detector 21 includes a control unit, a judgment unit, a detection unit, and an alarm unit. The judgment unit, the detection unit, and the alarm unit are each electrically connected to the control unit. The detection unit detects data from the transmission component 11 and transmits the data to the control unit. The control unit transmits the data to the judgment unit, which then makes a judgment. The judgment unit transmits the judgment result to the control unit, which then determines whether to control the alarm unit to sound an alarm based on the judgment information.

[0052] In one embodiment, Figure 1-2 As shown, a tensioning adjusting member 13 is provided on the mechanism bracket 12. The tensioning adjusting member 13 is used to adjust the tension of the transmission belt 113.

[0053] Specifically, the transmission mechanism 1 further includes a tensioning adjusting member 13, which is connected to the transmission belt 113. The transmission belt 113 may become loose after repeated use, and the tensioning adjusting member 13 is used to tighten the transmission belt 113 to avoid affecting the detection accuracy.

[0054] Optionally, the tensioning adjustment member 13 includes a bracket and an adjustment roller. The adjustment roller is located between the first transmission member 111 and the second transmission member 112 and is slidably connected to the bracket. The adjustment roller can slide vertically on the bracket. When the adjustment roller slides downward on the bracket, the adjustment roller causes a portion of the transmission belt 113 to stretch downward, thereby tightening the transmission belt 113.

[0055] In one embodiment, Figure 1 As shown, the tensioning adjusting member 13 is a toothed tensioning adjusting device, the transmission belt 113 is a toothed belt, and the adjusting end of the toothed tensioning adjusting device is connected to the connecting teeth of the toothed belt.

[0056] Specifically, the inner surface of the transmission belt 113 is provided with connecting teeth, and the adjustment end of the toothed tensioning adjuster is connected to the connecting teeth. The toothed tensioning adjuster is a prior art device specifically designed for adjusting toothed belts. This arrangement makes it easier to adjust the tension of the transmission belt 113.

[0057] In one embodiment, Figure 1 and Figure 3 As shown, the jam detection device 10 also includes a reset support mechanism 3, which is connected to the lower end of the transmission mechanism 1. When the object to be detected drives the transmission component 11 to move, the transmission mechanism 1 moves downward and presses the reset support mechanism 3. When the object to be detected leaves the transmission component 11, the reset support mechanism 3 pushes the transmission mechanism 1 to reset.

[0058] Specifically, the jam detection device 10 is further provided with a reset support mechanism 3, which is located below the transmission mechanism 1 and supports the transmission mechanism 1. The transmission mechanism 1 is located below the trolley straightening wheels 40 and can move up and down relative to the trolley straightening wheels 40. For ease of description, the transmission mechanism 1 is defined as having a first position and a second position, with the second position being located below the first position.

[0059] When the transmission belt 113 of the transmission component 11 is not in contact with the trolley straightening wheel 40, the transmission mechanism 1 is in the first position. When the trolley straightening wheel 40 is in contact with the transmission belt 113, the trolley straightening wheel 40 presses down the transmission component 11, so that the transmission mechanism 1 moves from the first position to the second position. The transmission mechanism 1 presses down the reset support mechanism 3, so that the reset support mechanism 3 is deformed. When the trolley straightening wheel 40 leaves the transmission belt 113, the reset support mechanism 3 recovers its deformation and pushes the transmission mechanism 1 upward, so that the transmission mechanism 1 returns to the first position. With this arrangement, each time the trolley 20 passes by, the transmission belt 113 can be in close contact with the trolley straightening wheel 40. And the trolley straightening wheel 40 has a stable positive pressure on the transmission belt 113, ensuring that there is no different friction between the trolley straightening wheel 40 and the transmission belt 113 due to different positive pressures.

[0060] Optionally, the transmission mechanism 1 can move vertically or rotate with one end as the center.

[0061] Optionally, the reset support mechanism 3 includes a telescopic spring and a support block, the telescopic spring is located below the mechanism bracket 12 , and the support block is connected between the telescopic spring and the mechanism bracket 12 .

[0062] In one embodiment, Figure 1 and Figure 3 As shown, the reset support mechanism 3 includes a support base 31 and a reset member 32 . The transmission mechanism 1 is movably connected to the support base 31 , and the reset member 32 is connected between the transmission mechanism 1 and the support base 31 .

[0063] Specifically, in certain embodiments, the reset support mechanism 3 comprises a support base 31 and a reset member 32. The support base 31 is located below the mechanism bracket 12, and one end of the mechanism bracket 12 is rotatably connected to the support base 31. The reset member 32 is connected to the mechanism bracket 12 at one end and to the support base 31 at the other end. This arrangement provides a simple structure, and the swinging design makes the transmission mechanism 1 more stable.

[0064] Specifically, in some embodiments, the reset support mechanism 3 is composed of a support seat 31 and a reset member 32. The support seat 31 is located below the mechanism bracket 12. One end of the mechanism bracket 12 is installed on the support seat 31 so as to be movable up and down. One end of the reset member 32 is connected to the mechanism bracket 12, and the other end is connected to the support seat 31. The structure thus arranged is simple, and the contact between the transmission belt 113 and the detected part is ensured by the force exerted by the reset member 32 on the mechanism bracket.

[0065] In one embodiment, Figure 1 and Figure 3 As shown, the reset member 32 includes a fixed block 321, a slider 322, a connecting rod 323, and a reset spring 324. The fixed block 321 is fixedly connected to the support base 31, the slider 322 is slidably connected to the support base 31, one end of the connecting rod 323 is hinged to the transmission mechanism 1, and the other end is hinged to the slider 322, and the reset spring 324 is connected between the slider 322 and the fixed block 321.

[0066] Specifically, the reset member 32 comprises a fixed block 321, a slider 322, a connecting rod 323, and a reset spring 324. The fixed block 321 is fixedly connected to the support base 31. The slider 322 is located on one side of the fixed block 321 and is slidably connected to the support base 31. The reset spring 324 has one end connected to the fixed block 321 and the other end connected to the slider 322. The connecting rod 323 has one end hinged to the slider 322 and the other end hinged to the mechanism bracket 12.

[0067] When the trolley straightening wheel 40 contacts the transmission belt 113, the mechanism bracket 12 swings downward, pushing the slider 322 toward the fixed block 321 via the connecting rod 323. At this point, the slider 322 squeezes the return spring 324, deforming it. When the trolley straightening wheel 40 leaves the transmission belt 113, the return spring 324 recovers its deformation, pushing the slider 322 away from the fixed block 321. The slider 322 then pushes the mechanism bracket 12 upward via the connecting rod 323. This configuration provides a guide for the slider 322, ensuring smoother up and down swinging of the mechanism bracket 12.

[0068] In one embodiment, Figure 1 and Figure 3 As shown, the jam detection device 10 further includes a base member 4, which includes a base plate 41 and a lifting adjustment member 42. The base plate 41 is located below the transmission mechanism 1, and the lifting adjustment member 42 is connected to the base plate 41 and is located between the base plate 41 and the transmission mechanism 1, and can lift the transmission mechanism 1.

[0069] Specifically, the transmission mechanism 1 and the reset support mechanism 3 are mounted on a base member 4. This embodiment will be used as an example for illustration. The base member 4 includes a base plate 41 and a lifting and adjusting member 42. The support base 31 is located above the base plate 41. The lifting and adjusting member 42 is connected between the base plate 41 and the support base 31. The lifting and adjusting member 42 drives the support base 31 up and down, thereby adjusting the height of the transmission mechanism 1 to accommodate different heights of the trolley straightening wheels 40.

[0070] Optionally, the lifting adjustment member 42 is a telescopic cylinder.

[0071] In one embodiment, Figure 1 and Figure 3 As shown, the lifting adjustment member 42 includes a screw rod 421 and a screw sleeve 422 . The screw rod 421 is connected to the base plate 41 . The screw sleeve 422 is threadedly connected to the screw rod 421 . The transmission mechanism 1 is supported on the screw sleeve 422 .

[0072] Specifically, the lifting adjustment member 42 consists of a screw 421 and a threaded sleeve 422. The screw 421 is fixed to the base plate 41, and the threaded sleeve 422 is inserted into the screw 421 and threadedly connected to the screw 421. The support base 31 is provided with a connecting hole, into which the screw 421 extends. The base plate 41 abuts against the threaded sleeve 422 and is supported by the threaded sleeve 422. By rotating the threaded sleeve 422, the position of the threaded sleeve 422 is adjusted, thereby adjusting the height of the support base 31.

[0073] Optionally, a support screw sleeve 422 and a limiting screw sleeve 422 are provided on the screw rod 421, the limiting screw sleeve 422 is located above the support screw sleeve 422, and the support seat 31 is sandwiched between the support screw sleeve 422 and the limiting screw sleeve 422. When adjusting the height of the support seat 31, the support screw sleeve 422 and the limiting screw sleeve 422 are rotated at the same time.

[0074] Optionally, in this embodiment, four screws 421 are provided on the base plate 41, so that the support is more stable.

[0075] like Figure 1-5 As shown, a trolley detection system 100 provided in one embodiment of the present invention includes a trolley 20, a trolley track 30 and any one of the above-mentioned jamming detection devices 10.

[0076] The trolley 20 is provided with trolley straightening wheels 40 . The trolley 20 is slidably connected to the trolley rail 30 , and the jam detection device 10 is fixedly connected to the trolley rail 30 .

[0077] When the trolley 20 passes through the jam detection device 10 , the trolley straightening wheels 40 come into contact with the transmission component 11 .

[0078] The trolley detection system 100 is applied to the electrophoresis line of the paint shop, so that the staff can detect the jamming of the trolley straightening wheel 40 and perform maintenance conveniently.

[0079] The trolley detection system 100 includes a trolley 20, a trolley track 30, and a jam detection device 10. The specific structure and function of the jam detection device 10 are described in the above related content and will not be repeated here.

[0080] The trolley 20 can slide on the trolley track 30, and the jam detection device 10 is installed on the trolley track 30. The bottom of the trolley 20 is provided with a trolley straightening wheel 40. When the trolley 20 slides on the trolley track 30 and passes through the jam detection device 10, the trolley straightening wheel 40 contacts the transmission belt 113 of the transmission component 11, and the detector 21 detects the trolley straightening wheel 40. This configuration allows jam detection to be performed every time the trolley 20 slides on the trolley track 30, and the condition of the trolley straightening wheel 40 is monitored in real time.

[0081] In one embodiment, Figure 4-5 As shown, the trolley track 30 is connected to an alignment track 50, which is located on one side of the jam detection device 10. The trolley straightening wheel 40 includes a connecting rod 401 and two rollers 402, which are connected to both ends of the connecting rod 401. When the trolley 20 passes through the jam detection device 10, one of the rollers 402 slides in contact with the alignment track 50, while the other roller 402 contacts the transmission component 11.

[0082] Specifically, the trolley track 30 also includes an alignment track 50, which is disposed opposite the jam detection device 10 and located on either side of the trolley track 30. The trolley straightening wheel 40 includes a connecting rod 401 and two rollers 402, each rotatably connected to the ends of the connecting rod 401. For ease of description, the roller 402 located on the same side as the jam detection device 10 is defined as the first roller, and the roller 402 located on the same side as the alignment track 50 is defined as the second roller.

[0083] When the trolley 20 passes through the jam detection device 10, the second roller enters and slides within the alignment track 50. The second roller is restrained within the alignment track 50, adjusting the angle of the trolley's straightening wheels 40 so that the first and second rollers are at the same height. After the height adjustment, the first roller contacts the transmission belt 113 of the transmission component 11. This arrangement reduces detection errors and improves detection accuracy.

[0084] like Figure 1-6 As shown, a method for detecting a trolley jam provided by the present invention is used to perform detection using any of the above-mentioned trolley detection systems 100. The detection steps are as follows:

[0085] S01: The trolley 20 slides on the trolley rail 30 and slides to the position of the adjustment rail 50.

[0086] S02 : When the trolley 20 passes through the straightening track 50 , one roller 402 of the trolley straightening wheel 40 slides on the straightening track 50 to adjust the height of the trolley straightening wheel 40 .

[0087] S03: When one of the rollers 402 of the trolley straightening wheel 40 slides on the straightening rail 50, the other roller 402 contacts the transmission component 11, driving the transmission component 11 to move.

[0088] S04: The detector 21 detects the data of the movement of the transmission component 11.

[0089] The trolley jam detection method uses a trolley detection system 100 for detection. The specific structure and function of the trolley detection system 100 refer to the relevant content mentioned above and will not be repeated here.

[0090] The specific detection method steps are as follows: the trolley 20 slides on the trolley track 30 on the production line. When it slides to the point where it is about to pass through the jam detection device 10, the second roller first enters the adjustment track 50, slides within the adjustment track 50, and is restrained by the adjustment track 50, so that the first roller and the second roller are at the same height. Then, the sliding continues, and the first roller contacts the transmission belt 113 on the transmission component 11, driving the transmission belt 113 to move. The movement of the transmission belt 113 drives the first transmission member 111 and the second transmission member 112 to rotate. The detector 21 detects the rotation of the first transmission member 111 or the second transmission member 112 to determine the jam condition of the trolley straightening wheel 40.

[0091] In summary, the present invention provides a jam detection device 10 , a trolley detection system 100 , and a trolley jam detection method.

[0092] The jam detection device 10 comprises a transmission mechanism 1 and a detection mechanism 2. The transmission mechanism 1 includes a transmission component 11, and the detection mechanism 2 includes a detector 21 for detecting jams. Detector 21 detects jams by measuring the movement of the transmission component 11. In this jam detection device 10, the transmission component 11 is driven by the part to be inspected, and the detector 21 detects jams by monitoring the movement of the transmission component 11. This changes the manual spot test method, facilitating inspections and improving efficiency.

[0093] The trolley detection system 100 includes a trolley 20, a trolley track 30, and a jam detection device 10. The trolley 20 is equipped with trolley straightening wheels 40, to which the trolley 20 is slidably connected. The jam detection device 10 is fixedly connected. When the trolley 20 passes through the jam detection device 10, the trolley straightening wheels 40 contact the transmission component 11. The jam detection device 10 detects the trolley 20 every time it passes, improving the quality and effectiveness of detection.

[0094] The steps of the trolley obstruction detection method include the trolley 20 sliding on the trolley track 30 to the position of the adjustment track 50. When the trolley 20 passes the adjustment track 50, one roller 402 of the trolley straightening wheel 40 slides on the adjustment track 50 to adjust the height of the trolley straightening wheel 40. When one of the rollers 402 of the trolley straightening wheel 40 slides on the adjustment track 50, the other roller 402 contacts the transmission component 11, driving the transmission component 11 to move. The detector 21 detects the data of the movement of the transmission component 11. Using this detection method to detect the obstruction of the trolley straightening wheel 40 is more convenient for the staff to operate, reduces work fatigue, and improves the detection accuracy.

[0095] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0096] The above are only the principles and preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several other variations can be made based on the principles of the present invention, which should also be considered as the scope of protection of the present invention.
