DETAILED DESCRIPTION

[0023] The utility model will be further described in detail below in combination with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the utility model, and not limited to the utility model. In addition, it should be noted that, in order to facilitate the description, only the part related to the utility model is shown in the drawings, not all structures.

[0024] In the description of the utility model, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication between two elements or the interaction between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0025] The utility model discloses an embodiment proposes a vehicle hasp in place detection mechanism, is fixed on hasp installation manipulator, and hasp installation manipulator is used for moving to the second part with hasp with the first part with hasp hole is grabbed to with hasp is inserted into hasp hole. The vehicle hasp in place detection mechanism includes first connecting piece 3, trigger piece 1 and monitoring piece 2, and first connecting piece 3 is fixed on hasp installation manipulator, and trigger piece 1 is slidably arranged on first connecting piece 3, and monitoring piece 2 is connected on hasp installation manipulator and moves synchronously with hasp installation manipulator. When hasp enters hasp hole and makes trigger piece 1 abut on hasp, hasp installation manipulator drives monitoring piece 2 to continue moving and makes trigger piece 1 move relative to monitoring piece 2 to make trigger piece 1 trigger monitoring piece 2.

[0026] The above-mentioned vehicle hasp in place detection mechanism can detect whether the hasp is inserted into the hasp hole as expected. During the movement of the first part driven by the hasp installation manipulator, if the hasp is inserted into the hasp hole, the trigger piece 1 can abut against the hasp and stop moving under the limitation of the hasp. Since the trigger piece 1 and the hasp installation manipulator can move relative to each other, the hasp installation manipulator drives the monitoring piece 2 to continue moving towards the second part. During this period, the trigger piece 1 and the monitoring piece 2 have relative displacement, the trigger piece 1 enters the preset monitoring range of the monitoring piece 2, and the monitoring piece 2 detects the presence of the trigger piece 1. If the hasp is not inserted into the hasp hole, the trigger piece 1, the hasp installation manipulator, and the monitoring piece 2 fixed on the hasp installation manipulator are relatively stationary, and the monitoring piece 2 cannot detect the presence of the trigger piece 1. That is, the vehicle hasp in place detection mechanism in the embodiment converts the direct detection of the hasp into the detection of the trigger piece 1, so that the trigger piece 1 is located on the path of the hasp inserted into the hasp hole. Even if the hasp inserted into the hasp hole is skewed to a certain extent, as long as it can be inserted into the hasp hole, the trigger piece 1 can enter the preset monitoring range of the monitoring piece 2 and be detected by the monitoring piece 2, thereby improving the detection accuracy.

[0027] In the embodiment, the monitoring piece 2 includes a distance sensor, which is arranged in the moving direction of the trigger piece 1 (i.e., coaxial or approximately coaxial with the trigger piece 1). When the trigger piece 1 moves to a distance less than the preset monitoring range of the distance sensor, the distance sensor outputs a signal. For example, if the preset monitoring range of the distance sensor is 5 mm, as long as the trigger piece 1 moves to a distance less than 5 mm from the distance sensor, it proves that the hasp is inserted into the hasp hole.

[0028] In other embodiments, the monitoring piece 2 includes a photoelectric sensor, and the emitter and receiver of the photoelectric sensor are correspondingly arranged in the direction perpendicular to the moving direction of the trigger piece 1, i.e., the light path of the photoelectric sensor is perpendicular to the moving direction of the trigger piece 1 on the first connecting piece 3. When the trigger piece 1 moves between the emitter and the receiver, it enters the preset monitoring range of the monitoring piece 2, and the photoelectric sensor outputs a signal.

[0029] Obviously, whether it is a distance sensor or a photoelectric sensor, its specific structure and the principle of detecting the trigger 1 are all existing technologies. In actual assembly, the monitoring component 2 can be selected by comprehensively considering factors such as cost, installation space, and ease of installation. The monitoring component 2 is connected to the external control device via a cable.

[0030] refer to Figure 2 As shown, the first connecting member 3 includes a guide block 32 and a first connecting plate 31. The guide block 32 is fixed to the hook-and-loop mounting robot arm via the first connecting plate 31. The guide block 32 has a guide hole for the trigger member 1 to pass through and guide the movement direction of the trigger member 1. The trigger member 1 is slidably disposed in the guide hole. Specifically, in order to reduce the friction between the trigger member 1 and the first connecting member 3, at least the part of the trigger member 1 that contacts the guide hole is cylindrical.

[0031] Specifically, the first connecting plate 31 has a strip-shaped hole. The first connecting plate 31 is connected to the mounting platform of the latch-on robot arm via fasteners passing through the strip-shaped hole. By adjusting the position of the fasteners within the strip-shaped hole, the initial position of the trigger element 1 can be fine-tuned, thereby reducing assembly errors. As for the guide block 32 and the first connecting plate 31, they can be integrally formed, or... Figure 2 As shown, the guide block 32 is fixed to the first connecting plate 31 by bolts, so as to facilitate the replacement of guide blocks 32 with guide holes of different sizes according to the current working conditions, thereby meeting different needs.

[0032] It is understood that the shape of the first connecting plate 31 is not specifically limited in this embodiment, and can be adaptively adjusted according to the position and shape of other components installed on the hook-and-loop installation robot.

[0033] In other embodiments, the first connector 3 includes a slider, and the trigger 1 is slidably disposed on the slider. At the same time, the slider is slidably disposed on the hook-and-loop mounting robot by means of a slide groove or slide rail disposed on the hook-and-loop mounting robot. After the slider position is adjusted, it is fixed to the slide rail or slide groove by fasteners, thereby fixing the slider on the hook-and-loop mounting robot.

[0034] In this embodiment, the vehicle buckle positioning detection mechanism also includes a second connector 4, which in turn includes a second connecting plate. Similar to the first connecting plate 31, the second connecting plate also has a strip hole and is connected to the buckle installation robot through a fastener passing through the strip hole. The monitoring component 2 is fixedly connected to the buckle installation robot through the second connector 4 to facilitate adjustment of the position of the monitoring component 2 on the buckle installation robot.

[0035] Specifically, the trigger 1 includes a main body 11, an abutment 12, and a trigger 13. The main body 11 is cylindrical, the abutment 12 and the trigger 13 are fixed on the main body 11, and the trigger 13 is located on the side of the main body 11 closer to the monitoring member 2, while the abutment 12 is located on the side of the main body 11 away from the monitoring member 2.

[0036] The circumferential contours of the abutment portion 12 and / or the trigger portion 13 are larger than the circumferential contours of the main body portion 11, thereby increasing the contact area between the trigger member 1 and the buckle or the trigger area of ​​the trigger member 1 triggering the monitoring member 2, thus further improving the monitoring effectiveness. In this embodiment, the abutment portion 12 is coaxially disposed at the end of the main body portion 11 and adopts a flat plate structure, so that the force direction of the trigger member 1 is as coaxial as possible with the main body portion 11, reducing the possibility of bending of the main body portion 11.

[0037] When the hook and loop is inserted into the hook and loop hole, the abutting part 12 can abut against the hook and loop. The monitoring part 2 essentially monitors the trigger part 13. The trigger part 13, which has a larger circumferential contour area than the main body part 11, is easier to be monitored by the monitoring part 2, which reduces the assembly accuracy requirements for the relative position between the monitoring part 2 and the trigger part 1.

[0038] The guide block 32 includes a first guide portion 321, and a guide hole is formed on the first guide portion 321. Based on the arrangement of the abutment portion 12 and the trigger portion 13, the first guide portion 321 is also provided with a second guide portion 322 and a third guide portion 323 on opposite sides along the length direction of the trigger member 1. The second guide portion 322 and the third guide portion 323 are located on opposite sides of the trigger member 1 and guide the abutment portion 12 and the trigger portion 13 respectively, thereby reducing the possibility of bending the trigger member 1 due to the push force applied to the trigger member 1 by the buckle being biased.

[0039] refer to Figure 1 As shown, the vehicle latching detection mechanism also includes a reset component 5, which is elastically connected between the trigger component 1 and the first connecting component 3. This reset component 5 is used to restore the trigger component 1 to its initial position for easier detection in the next step. In this embodiment, the reset component 5 is a spring, which is sleeved on the trigger component 1 and located between the first guide portion 321 and the abutment portion 12, or between the first guide portion 321 and the trigger portion 13. If the spring is located between the first guide portion 321 and the abutment portion 12, it is a tension spring; if it is located between the first guide portion 321 and the trigger portion 13, it is a compression spring. Clearly, when the spring is in its natural state, the trigger portion 13 is not within the preset monitoring range of the monitoring component 2.

[0040] To promptly alert the operator whether the hook and loop fastener is properly inserted into the fastener hole, the vehicle hook and loop positioning detection mechanism also includes an alert unit, which is communicatively connected to the monitoring component 2. When the monitoring component 2 detects the trigger component 1, it sends a signal to the alert unit, which indicates that the hook and loop fastener is installed correctly. Otherwise, assuming the hook and loop fastener installation robot is in position, if the monitoring component 2 does not detect the trigger component 1, the alert unit indicates that the hook and loop fastener is not installed correctly, requiring the operator to handle it promptly. The alert unit can be a buzzer, indicator light, or display; no specific limitation is made here.

[0041] This embodiment also proposes a vehicle latch installation device for performing vehicle latch installation. The vehicle latch installation device includes the aforementioned latch installation robot and the aforementioned vehicle latch positioning detection mechanism. The latch installation robot further includes a moving mechanism, a gripping mechanism, and a pushing mechanism. The gripping mechanism, the pushing mechanism, and the vehicle latch positioning detection mechanism are all located at the output end of the moving mechanism. The moving mechanism drives the gripping mechanism, the pushing mechanism, and the vehicle latch positioning detection mechanism to move towards the location of the second part. The gripping mechanism grips the first part. As the moving mechanism moves, the latch on the qualified part can be inserted into the latch hole. The pushing mechanism includes a driving member and a pushing member. The driving member is located at the output end of the moving mechanism, and the pushing member is located at the output end of the driving member. The driving member is configured to drive the pushing member to move so that the pushing member pushes the latch, thereby bending the latch and completing the latch installation.

[0042] The aforementioned vehicle latch installation device uses a vehicle latch positioning detection mechanism to detect whether the latch is inserted into the latch hole as expected. If the positioning detection mechanism detects that the latch is inserted into the latch hole as expected, the pushing mechanism pushes the latch, causing the latch to bend and completing the latch installation.

[0043] In this embodiment, the driving component includes a cylinder. The cylinder is simple to operate and has a fast response speed. Moreover, whether the latch is properly engaged can be determined by whether the extension end of the cylinder moves to a preset position. The pushing component includes a roller, which is rotatably disposed at the extension end of the cylinder. Using a roller to push the latch reduces damage to the latch and the roller itself, which helps to improve the service life of the assembled body-in-white and the entire vehicle latch installation device.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
