Description

Technical Field

[0001] The present application relates to the technical field of automated detection devices, and in particular to a deviation detection mechanism. Background Art

[0002] At present, multiple devices, especially processing equipment, are usually installed according to the flow direction of the product, and there is a preset installation distance between the multiple devices. During the operation of the equipment, multiple devices may shift due to vibration, collision, etc. If the offset between the multiple devices exceeds the preset range, it will affect the product flow and the processing operations of each device on the product.

[0003] In order to solve the above problem, currently, inspectors usually regularly detect and correct the offsets between multiple devices. However, since inspectors cannot know in advance which devices have offsets within a preset range and which devices have offsets beyond the preset range, inspectors need to cover all devices each time they detect and correct the offsets between multiple devices, which affects the efficiency of detecting and correcting the offsets between multiple devices. Utility Model Content

[0004] In view of the above, it is necessary to propose an offset detection mechanism to improve the efficiency of detecting and correcting the offset between multiple devices.

[0005] The embodiment of the present application provides an offset detection mechanism for detecting the offset between a first device and a second device, including a limit assembly and an offset detection assembly; the limit assembly is used to connect with the first device, and the limit assembly is provided with a limit hole extending along a first direction; the offset detection assembly includes a base, a support member, a first sensing member, an abutment member and a pressing member, the base extends toward the limit assembly and is used to connect with the second device, the support member is penetrated through the limit hole along the first direction and connected to one end of the base close to the limit assembly, and the support member is provided with a contact hole coexisting with the limit hole The shaft is provided with a receiving hole, the first sensing member is accommodated in one end of the receiving hole close to the base, the abutment member comprises a trigger portion and a stop portion, the trigger portion is slidably provided at one end of the receiving hole away from the base and extends toward the first sensing member, the stop portion is connected to one end of the trigger portion away from the first sensing member and is slidably sleeved on the support member, the cross-sectional size of the stop portion is smaller than the cross-sectional size of the limiting hole, the stop portion is used to drive the trigger portion to trigger the first sensing member when extending into the limiting hole, and the pressing assembly is provided on the base and is used to press the stop portion.

[0006] The offset detection mechanism of the embodiment of the present application is provided with a limit assembly and an offset detection assembly respectively connected to the first device and the second device.

In this way, when the inspector detects and corrects the offset between multiple devices, it can be known in advance which devices have an offset within the preset range and which devices have an offset beyond the preset range, so that the inspector only detects and corrects the devices whose offset exceeds the preset range, thereby improving the efficiency of detecting and correcting the offset between multiple devices.

Some embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0069] See also Figure 1 and Figure 5 , the embodiment of the present application provides an offset detection mechanism 100 for detecting the offset between the first device 300 and the second device 400. The first device 300 and the second device 400 may be processing equipment, detection equipment, feeding equipment, etc. For ease of understanding and explanation, the embodiment of the present application takes the first device 300 as a CNC machine tool and the second device 400 as a feeding equipment as an example, and defines the first direction as Figure 1 and Figure 2 The Z-axis direction is shown, and the second direction is Figure 1 and Figure 2 In the X-axis direction shown, the first direction and the second direction are perpendicular to each other. Obviously, this is not a limitation of the embodiments of the present application.

[0070] See also Figure 1 , Figure 2 and Figure 5In one embodiment, the offset detection mechanism 100 includes a limit assembly 10 and an offset detection assembly 20 .

[0071] The limiting assembly 10 is connected to the first device 300 , and the limiting assembly 10 is provided with a limiting hole 121 extending along the first direction.

[0072] The offset detection component 20 includes a base 21, a support member 22, a first sensor 231, an abutment member 24 and a pressing component 25. The base 21 extends toward the limiting component 10 and is connected to the second device 400. The support member 22 is arranged in the limiting hole 121 along the first direction and is connected to an end of the base 21 close to the limiting component 10. The support member 22 is provided with a receiving hole 221 coaxially arranged with the limiting hole 121. The first sensor 231 is accommodated in the end of the receiving hole 221 close to the base 21. The abutment member 24 includes a trigger portion 241 and The stopper 242 and the triggering part 241 are slidably disposed at one end of the storage hole 221 away from the base 21 and extend toward the first sensing member 231. The stopper 242 is connected to one end of the triggering part 241 away from the first sensing member 231 and is slidably sleeved on the support member 22. The cross-sectional dimension of the stopper 242 is smaller than the cross-sectional dimension of the limiting hole 121. The stopper 242 is used to drive the triggering part 241 to trigger the first sensing member 231 when extending into the limiting hole 121. The pressing assembly 25 is disposed on the base 21 and is used to press the stopper 242.

[0073] Specifically, the first sensing element 231 can be a functional sensor such as a proximity switch or a photoelectric sensor that can sense the position of an object. When the first device 300 and the second device 400 are installed at a preset distance, the limit assembly 10 is connected to the first device 300, and the base 21 of the offset detection assembly 20 is connected to the second device 400, then the offset between the first device 300 and the second device 400 will cause the stopper 242 to offset the limit hole 121. When the inspector detects and corrects the offset between the first device 300 and the second device 400, the pressure component 25 is started and pressed against the stopper 242. If the offset between the first device 300 and the second device 400 is within a preset range, the stopper 242 extends into the limiting hole 121 under the pressure of the pressure component 25, and the stopper 242 drives the triggering part 241 to move toward the first sensing part 231 and trigger the first sensing part 231. If the offset between the first device 300 and the second device 400 exceeds the preset range, the offset between the stopper 242 and the limiting hole 121 is large, and the stopper 242 cannot extend into the limiting hole 121 under the pressure of the pressure component 25. The stopper 242 stops on the side of the limiting component 10 away from the base 21. At this time, the triggering part 241 will not trigger the first sensing part 231. In this way, when inspectors detect and correct the offset between multiple devices, they can know in advance which devices have offsets within a preset range and which devices have offsets beyond the preset range, so that inspectors only detect and correct devices whose offsets exceed the preset range, thereby improving the efficiency of detecting and correcting the offset between multiple devices.

[0074] In one embodiment, the first sensing element 231 is connected to the base 21 and extends into the receiving hole 221 close to one end of the base 21 , so as to facilitate the installation of the first sensing element 231 .

[0075] In one embodiment, the offset detection mechanism 100 also includes a controller (not shown), which is electrically connected to the pressing component 25 and the first sensing member 231. The controller controls the pressing component 25 to start and stop according to instructions, and the controller determines whether the offset between the first device 300 and the second device 400 exceeds a preset range based on the sensing information of the first sensing member 231.

[0076] In one embodiment, the limit assembly 10 includes a connector 11 and a limit assembly 12. The connector 11 is connected to the first device 300, and there is a movable gap 13 between one end of the connector 11 and one end of the base 21 provided with the support member 22, and the other end of the connector 11 is away from the base 21 along the first direction; the limit assembly 12 is provided at one end of the connector 11 away from the base 21 and is spaced from the base 21, and the limit hole 121 is provided in the limit assembly 12. The movable gap 13 can reserve space for the limit assembly 10 and the offset detection assembly 20 to move relative to each other. When the first device 300 and the second device 400 are offset, the limit assembly 10 and the offset detection assembly 20 are respectively offset under the drive of the first device 300 and the second device 400, so that the stopper 242 and the limit hole 121 are offset, which is conducive to improving the accuracy of the offset detection mechanism 100 in detecting the offset between the first device 300 and the second device 400. In addition, by arranging the limit member 12 at one end of the connecting member 11 away from the base 21 and spaced apart from the base 21, and by opening the limit hole 121 in the limit member 12, it is convenient to pass the support member 22 through the limit hole 121 when installing the limit assembly 10 and the offset detection assembly 20, and it is convenient to adjust the relative position of the stop portion 242 and the limit hole 121.

[0077] In one embodiment, a first mounting hole 111 is opened at one end of the connecting member 11 close to the base 21, and the connecting member 11 is connected to the first device 300 by a bolt (not shown) passing through the first mounting hole 111, thereby improving the convenience of connecting the connecting member 11 to the first device 300.

[0078] In one embodiment, a mounting groove 112 and a second mounting hole 113 connected to the mounting groove 112 are formed at one end of the connecting member 11 away from the base 21, and the limiting member 12 is arranged in the mounting groove 112. The connecting member 11 is connected to the limiting member 12 by bolts passing through the second mounting hole 113, thereby improving the convenience and stability of connecting the connecting member 11 and the limiting member 12.

[0079] In one embodiment, the connecting member 11 is wedge-shaped, and the cross-sectional dimension of the end of the connecting member 11 away from the base 21 is larger than the cross-sectional dimension of the end of the connecting member 11 close to the base 21, thereby facilitating the stability of the connecting member 11 supporting the limit member 12 and facilitating the structural strength of the limit assembly 10.

[0080] In one embodiment, the limiting hole 121 and the storage hole 221 are both circular holes, the support member 22 and the trigger portion 241 are both cylindrical, the cross-section of the stopping portion 242 is circular, the diameter of the stopping portion 242 is larger than the diameter of the support member 22 and smaller than the diameter of the limiting hole 121, and the difference between the diameter of the stopping portion 242 and the diameter of the limiting hole 121 is set according to a preset range of the offset between the first device 300 and the second device 400.

[0081] Please refer to Figure 3 In one embodiment, a contact hole 2421 is formed on one side of the stop portion 242 facing the trigger portion 241, and the contact hole 2421 is a blind hole. The trigger portion 241 is connected to the bottom wall of the contact hole 2421, and the stop portion 242 and the trigger portion 241 are coaxially arranged, and one end of the support member 22 away from the base 21 extends into the contact hole 2421, so that the stop portion 242 can drive the trigger portion 241 to move relative to the support member 22 under the pressing action of the pressing assembly 25. A limiting protrusion 222 is circumferentially protruded from one end of the support member 22 away from the base 21, and an insertion hole 2422 connected to the abutment hole 2421 is formed on the side wall of the stop portion 242. The offset detection assembly 20 also includes a limiting member 26, which can be a screw. The limiting member 26 is inserted into the insertion hole 2422 and extends into the abutment hole 2421, and the end of the limiting member 26 extending into the insertion hole 2422 is located on the side of the limiting protrusion 22 facing the base 21. The limiting member 26 limits the end of the support member 22 away from the base 21 from escaping from the abutment hole 2421, which is beneficial to improving the stability of the connection between the stop portion 242 and the support member 22.

[0082] In one embodiment, the offset detection assembly 20 further includes a first elastic member 27, which may be a spring. The first elastic member 27 is sleeved on the first sensing member 231 and the triggering portion 241, and the two ends of the first elastic member 27 are respectively in contact with the base 21 and the stopper 242. The first elastic member 27 can elastically support the stopper 242, and drive the stopper 242 to return quickly when the pressing assembly 25 is separated from the stopper 242, so as to facilitate the use of the offset detection mechanism 100 to re-detect the offset between the first device 300 and the second device 400.

[0083] In one embodiment, the pressing assembly 25 includes a sliding driving member 251 and a sliding member 252. The sliding member 252 is slidably disposed on the base 21 along the second direction and extends toward the stopper 242; the sliding driving member 251 is disposed on the base 21 and connected to the sliding member 252, and the sliding driving member 251 is used to drive the sliding member 252 to press against the stopper 242. In this way, the accuracy of the pressing assembly 25 pressing against the stopper 242 is improved.

[0084] In one embodiment, the sliding driving member 251 is a telescopic cylinder, and the sliding driving member 251 is electrically connected to the controller, so that the sliding driving member 251 can be controlled by the controller to drive the sliding member 252 to press the stopper 242. In some other embodiments, the sliding driving member 251 can also be a power member such as an electric push rod, which is not specifically limited in the embodiment of the present application.

[0085] Please refer to further Figure 4 In one embodiment, the sliding member 252 includes a sliding portion 2521, an extension portion 2522, and a pressing portion 2523 connected in sequence. The sliding portion 2521 is slidably disposed on the base 21 along the second direction and connected to the sliding driving member 251. The extension portion 2522 is obliquely connected to the sliding portion 2521, and the angle between the extension portion 2522 and the sliding portion 2521 is an obtuse angle. The pressing portion 2523 is spaced apart from the base 21 and extends toward the stopper 242. The pressing portion 2523 has a pressing surface 2523a for pressing the stopper 242 on one side facing the base 21. When the sliding driving member 251 drives the sliding member 252 to move toward the stopper 242, the extension portion 2522 and the pressing portion 2523 convert the thrust of the sliding member 252 along the second direction into a pressing force along the first direction, thereby facilitating the improvement of the accuracy of the sliding member 252 pressing the stopper 242.

[0086] In one embodiment, the side of the pressing portion 2523 away from the extending portion 2522 further has a guide arc surface 2523b adjacent to the pressing surface 2523a. By providing the guide arc surface 2523b, when the pressing portion 2523 abuts against the stopper 242, the guide arc surface 2523b first abuts against the stopper 242 and guides the stopper 242 to the pressing surface 2523a, thereby reducing the impact force of the pressing portion 2523 on the stopper 242, and further reducing the probability of damaging the abutting member 24 and the supporting member 22. In addition, by setting the guiding arc surface 2523b, the pressing surface 2523a can be set lower than the stop portion 242. When the guiding arc surface 2523b guides the stop portion 242 to the pressing surface 2523a, the pressing surface 2523a can press the stop portion 242 to move a greater distance, thereby helping to improve the sensitivity of the stop portion 242 to drive the trigger portion 241 to trigger the first sensing element 231.

[0087] Please refer again Figure 1 and Figure 2 In one embodiment, a sliding groove 211 extending along the second direction is formed on the base 21, and two opposite groove walls of the sliding groove 211 are respectively formed with guide grooves 2111, and the sliding portion 2521 is slidably disposed in the sliding groove 211, and two opposite side walls of the sliding portion 2521 are respectively provided with sliding protrusions 2521a slidably matched with the corresponding guide grooves 2111. In this way, the sliding portion 2521 is conducive to improving the accuracy and stability of sliding on the base 21 along the second direction.

[0088] In one embodiment, the sliding portion 2521 is provided with a sliding hole 2521b and a mounting groove 2521c extending along the second direction, the mounting groove 2521c is located in the middle of the sliding portion 2521, the sliding hole 2521b is located at one end of the sliding portion 2521 away from the extension portion 2522 and is connected to the mounting groove 2521c, the sliding drive member 251 is located on a side of the sliding portion 2521 away from the extension portion 2522, the sliding drive member 251 has an output shaft 2511, the output shaft 2511 slides through the sliding hole 2521b and extends into the mounting groove 2521c. The offset detection assembly 20 also includes a resistance member 28 and a second elastic member 29, the resistance member 28 is connected to one end of the output shaft 2511 of the sliding drive member 251 located in the mounting groove 2521c and extends along the second direction toward the mounting groove 2521c away from the end of the output shaft 2511; the second elastic member 29 can be a spring, the second elastic member 29 is sleeved on the resistance member 28 and the two ends are respectively connected to the resistance member 28 and the inner wall of the mounting groove 2521c away from the output shaft 2511. When the sliding drive member 251 drives the resistance member 28 to move toward the installation groove 2521c away from one end of the output shaft 2511, the sliding drive member 251 drives the sliding member 252 to slide through the resistance member 28 and the second elastic member 29. If the offset between the first device 300 and the second device 400 exceeds the preset range, the stop portion 242 cannot enter the limiting hole 121. At this time, the stop portion 242 stops the sliding member 252 and compresses the second elastic member 29. The second elastic member 29 drives the sliding member 252 to elastically abut against the stop portion 242, which helps to reduce the probability of damaging the sliding member 252 and the abutment member 24.

[0089] In one embodiment, the mounting groove 2521c is a through groove. In some other embodiments, the mounting groove 2521c may also be a blind groove, which is not specifically limited in the embodiment of the present application.

[0090] In one embodiment, the offset detection assembly 20 further includes a second sensor 232, which is disposed at one end of the sliding portion 2521 close to the extension portion 2522, and the second sensor 232 extends into the mounting slot 2521c and faces the abutment 28. The second sensor 232 is used to sense the position of the abutment 28 to determine whether the offset between the first device 300 and the second device 400 exceeds a preset range. Specifically, the second sensor 232 may also be a functional sensor such as a proximity switch or a photoelectric sensor that can sense the position of an object. When the offset between the first device 300 and the second device 400 does not exceed the preset range, the sliding driving member 251 drives the sliding member 252 to slide toward the stopper 242 and press the stopper 242 through the abutment 28 and the second elastic member 29, and the stopper 242 enters the limiting hole 121 and drives the triggering member 241 to trigger the first sensing member 231. When the offset between the first device 300 and the second device 400 exceeds the preset range, the stopper 242 cannot enter the limiting hole 121, and the stopper 242 stops the sliding member 252 and compresses the second elastic member 29. At this time, the sliding driving member 251 drives the abutment 28 to trigger the second sensing member 232. In this way, it is helpful to improve the accuracy of the offset detection mechanism 100 in detecting the offset between the first device 300 and the second device 400.

[0091] In one embodiment, the second sensing element 232 is also electrically connected to the controller, so that the controller can accurately determine whether the offset between the first device 300 and the second device 400 exceeds a preset range based on the sensing information of the second sensing element 232 .

[0092] In one embodiment, an assembly hole 2521d is formed on the inner wall of the installation groove 2521c away from the output shaft 2511 and is connected to the installation groove 2521c and opposite to the abutment member 28. The second sensing member 232 is installed in the assembly hole 2521d, which is conducive to improving the convenience of installing the second sensing member 232.

[0093] In one embodiment, the abutment member 28 includes a blocking portion 281 and an abutment member 282. The blocking portion 281 is plate-shaped and connected to one end of the output shaft 2511 of the sliding driving member 251 located in the mounting groove 2521c. The abutment member 282 is column-shaped and connected to the side of the blocking portion 281 away from the output shaft 2511 of the sliding driving member 251, and extends along the second direction toward the end of the mounting groove 2521c away from the output shaft 2511. The second elastic member 29 is sleeved on the abutment member 282, and the two ends of the second elastic member 29 are respectively abutted against the blocking portion 281 and the inner wall of the mounting groove 2521c away from the output shaft 2511. This is conducive to improving the convenience of installing the second elastic member 29. In addition, when the sliding drive member 251 drives the resistance member 28 to return, the blocking portion 281 can also push the sliding member 252 to return, thereby facilitating the use of the offset detection mechanism 100 to re-detect the offset between the first device 300 and the second device 400.

[0094] To summarize, the offset detection mechanism 100 of the embodiment of the present application is provided with a limit assembly 10 and an offset detection assembly 20 respectively connected to the first device 300 and the second device 400. When the inspector detects and corrects the offset between the first device 300 and the second device 400, he only needs to start the pressing assembly 25 and make the pressing assembly 25 press the stopper 242. If the offset between the first device 300 and the second device 400 is within a preset range, the stopper 242 extends into the limit hole 121 under the pressing action of the pressing assembly 25, and the stopper 242 drives the triggering portion 241 to move toward the first sensing member 231 and trigger the first sensing member 231. If the offset between the first device 300 and the second device 400 exceeds the preset range, the stopper 242 stops at the side of the limit assembly 10 away from the base 21, and the stopper 242 will not drive the triggering portion 241 to trigger the first sensing member 231. In this way, when inspectors detect and correct the offset between multiple devices, they can know in advance which devices have offsets within a preset range and which devices have offsets beyond the preset range, so that inspectors only detect and correct devices whose offsets exceed the preset range, thereby improving the efficiency of detecting and correcting the offset between multiple devices.
