Description

Technical Field

[0001] This invention relates to the field of conveyor technology, and in particular to a conveyor detection and adjustment mechanism. Background Technology

[0002] In automated side panel production lines for vehicles, the transfer of finished side panels to the next process typically employs an automated conveyor system. This system mainly consists of a conveyor track and a transfer rack for placing parts. After side panel processing, the parts are transported to the transfer rack by a robot. Due to prolonged use and vibrations during transport, the V-shaped support wheels and limit slots on the transfer rack are prone to wear and misalignment. This can cause the parts to be misaligned when placed by the transplanting machine or robot, and in severe cases, it can lead to safety accidents such as parts falling off.

[0003] The applicant has discovered at least the following technical problems in the prior art: The prior art involves manual inspection and maintenance of the conveyor frame, but the accuracy of manual operation cannot be effectively guaranteed. Therefore, when placement is misaligned, it can cause poor gripping of parts by the robot in the next process, leading to collision accidents and resulting in damage to robot parts, misalignment of gripping parts, or machine malfunctions. The falling or collision of parts causes parts to be scrapped, increasing production costs or machine maintenance costs and causing safety accidents. The occurrence of these problems directly affects the production utilization rate. Summary of the Invention

[0004] The purpose of this invention is to provide a conveyor frame inspection and adjustment mechanism to solve the technical problems in the prior art where manual inspection and maintenance of the conveyor frame cannot guarantee accuracy, easily leading to safety accidents and increasing production costs. The various technical effects of the preferred technical solutions provided by this invention are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A conveyor frame detection and adjustment mechanism includes a fixed support, a moving unit, a placement wheel arc detector, a V-groove detector, a positioning fork detector, and a precision indication unit. Several moving units are connected to the fixed support. The placement wheel arc detector, the V-groove detector, and the positioning fork detector are all connected to the moving units. The moving units can drive the placement wheel arc detector, the V-groove detector, and the positioning fork detector to move vertically. The precision indication unit is connected to both the moving units and the fixed support, and can indicate precision.

[0007] Preferably, the moving unit includes a slide rail, a movable base, and a spring-loaded slot positioning pin. The slide rail is connected to the fixed bracket, and the movable base is slidably connected to the slide rail. The placement wheel arc detector, the V-groove detector, the positioning fork detector, and the spring-loaded slot positioning pin are all connected to the movable base and can move synchronously with the movable base. The fixed bracket is provided with a pin positioning hole at the extreme position of the downward movement of the spring-loaded slot positioning pin, and the spring-loaded slot positioning pin can be inserted into the pin positioning hole.

[0008] Preferably, the moving unit further includes a movable handle, which is connected to the movable base.

[0009] Preferably, the precision indicating unit includes a precision adjustment indicator and a precision indicating ruler. The precision adjustment indicator is connected to the fixed bracket and located on one side of the slide rail, and the precision indicating ruler is connected to the movable base and can move synchronously with the movable base.

[0010] Preferably, there are three moving units, which are arranged sequentially. The middle moving unit is connected to the positioning fork detector, and the other two moving units are each connected to a placement wheel arc detector and a V-groove detector.

[0011] Preferably, it also includes a maintenance and adjustment track, and the conveyor frame is slidably connected to the maintenance and adjustment track.

[0012] Preferably, it further includes a positioning and locking mechanism connected to the maintenance and adjustment track, the positioning and locking mechanism being capable of clamping the conveyor frame to restrict the movement of the conveyor frame in the front-to-back direction.

[0013] Preferably, it also includes an L-shaped positioning mechanism, which is connected to the maintenance and adjustment track. The conveyor frame is provided with a positioning pulley that contacts the L-shaped positioning mechanism. The L-shaped positioning mechanism can restrict the movement of the conveyor frame in the left and right directions.

[0014] The beneficial effects of this invention are as follows: the placement wheel arc detector and the V-groove detector can detect the position of the V-shaped part placement wheel and the wear of the V-groove on the conveyor frame, respectively. Furthermore, the wear, deformation, or misalignment of the V-shaped part placement wheel can be determined by comparing the current value indicated by the accuracy indicator unit with the accuracy standard set by the detection and adjustment mechanism. If adjustment or replacement is required, the accuracy standard set by the conveyor frame detection and adjustment mechanism shall be used as the basis, thereby effectively ensuring that the usage accuracy of all conveyor frames is consistent.

[0015] The positioning fork arm detector can detect the positioning distance and wear condition of the positioning fork arms on the conveyor frame, and adjust or replace them based on the distance of the positioning fork arm detector.

[0016] The conveyor inspection and adjustment mechanism can effectively ensure the accuracy of conveyor inspection and maintenance, ensure the positional accuracy of the robot when placing and picking up parts, prevent abnormalities in the robot's picking and placing of parts that may lead to parts falling, collisions, or machine repairs, and ensure the smooth completion of the company's production utilization rate.

Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0032] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] Reference Figures 1 to 4 The present invention provides a conveyor frame detection and adjustment mechanism, including a fixed support 1, a moving unit 2, a placement wheel arc detector 31, a V-groove detector 32, a positioning fork detector 33, and a precision indication unit 4. Several moving units 2 are connected to the fixed support 1. The placement wheel arc detector 31, the V-groove detector 32, and the positioning fork detector 33 are all connected to the moving units 2. The moving units 2 can drive the placement wheel arc detector 31, the V-groove detector 32, and the positioning fork detector 33 to move in the vertical direction. The precision indication unit 4 is connected to the moving units 2 and the fixed support 1 respectively, and the precision indication unit 4 can indicate the precision.

[0034] The placement wheel arc detector 31 and the V-groove detector 32 can detect the position of the V-shaped part placement wheel and the wear of the V-groove on the conveyor frame 8, respectively. They can also compare the current value indicated by the accuracy indicator unit 4 with the accuracy standard set by the detection and adjustment mechanism to determine the wear, deformation or misalignment of the V-shaped part placement wheel. If adjustment or replacement is required, the accuracy standard set by the conveyor frame detection and adjustment mechanism shall be used as the basis, thereby effectively ensuring that the usage accuracy of all conveyor frames 8 is consistent.

[0035] The positioning fork arm detector 33 can detect the positioning distance and wear condition of the positioning fork arm on the conveyor frame 8, and adjust or replace it based on the distance of the positioning fork arm detector 33.

[0036] The conveyor inspection and adjustment mechanism can effectively ensure the accuracy of conveyor inspection and maintenance, ensure the positional accuracy of the robot when placing and picking up parts, prevent abnormalities in the robot's picking and placing of parts that may lead to parts falling, collisions, or machine repairs, and ensure the smooth completion of the company's production utilization rate.

[0037] As an optional implementation, the moving unit 2 includes a slide rail 21, a movable base 22 and a spring-loaded slot positioning pin 23. The slide rail 21 is connected to the fixed bracket 1. The connection here is preferably a fixed connection to make the connection firm and prevent the slide rail 21 from moving relative to the bracket.

[0038] The movable base 22 is slidably connected to the slide rail 21, and the movable base 22 can move relative to the slide rail 21 under the action of external force;

[0039] The placement wheel arc detector 31, V-groove detector 32 and positioning fork arm detector 33 are all connected to the movable base 22 and can move synchronously with the movable base 22. When they move upward to the limit position, they can detect the position of the V-shaped part placement wheel, the wear condition of the V-groove, the positioning distance of the positioning fork arm and the wear condition of the positioning fork arm respectively.

[0040] The spring-loaded slot positioning pin 23 is connected to the movable base 22 and can move synchronously with the movable base 22. The fixed bracket 1 is provided with a pin positioning hole at the extreme position of the downward movement of the spring-loaded slot positioning pin 23. When the movable base 22 does not need to move, the spring-loaded slot positioning pin 23 can be inserted into the pin positioning hole. When the movable base 22 needs to move, the insertion between the spring-loaded slot positioning pin 23 and the pin positioning hole can be directly released. At this time, the movable base 22 can move freely under the action of external force.

[0041] As an optional implementation, the moving unit 2 also includes a movable handle 24, which is connected to the movable base 22. The movable handle 24 is easier for a person to hold, and the operator can move the movable base 22 as a whole by holding the movable handle 24, making the movement of the movable base 22 more convenient and faster.

[0042] As an optional implementation, the precision indication unit 4 includes a precision adjustment indicator 41 and a precision indicator ruler 42. The precision adjustment indicator 41 is connected to the fixed bracket 1 and located on one side of the slide rail 21. The precision indicator ruler 42 is connected to the movable base 22 and can move synchronously with the movable base 22. After the movable base 22 moves to the corresponding position, the tip on the precision adjustment indicator 41 can correspond to the reading on the precision indicator ruler 42, thereby forming an effective indication of the precision and providing the operator with an adjustment basis.

[0043] As an optional implementation, there are three moving units 2, which are arranged sequentially. The middle moving unit 2 is connected to a positioning fork arm detector 33, and the other two moving units 2 are each connected to a placement wheel arc detector 31 and a V-groove detector 32. This arrangement can match the specific number and position of the placement wheel, V-groove and positioning fork arm on the conveyor frame 8 shown in the attached drawings of this embodiment. The specific number of moving units 2 and the specific form of the detectors connected to the moving units 2 can be flexibly selected according to actual use needs.

[0044] Example 2

[0045] Based on Embodiment 1, as an optional implementation, the conveyor frame detection and adjustment mechanism further includes a maintenance and adjustment track 5. The conveyor frame 8 is slidably connected to the maintenance and adjustment track 5. The maintenance and adjustment track 5 is a dedicated track, preferably located above the fixed support 1. The maintenance and adjustment track 5 can be distinguished from the original conventional track, forming an independent track, which helps to form a dedicated maintenance space.

[0046] As an optional implementation, a positioning and locking mechanism 6 is also included. The positioning and locking mechanism 6 is connected to the maintenance and adjustment track 5. The positioning and locking mechanism 6 can clamp the conveyor frame 8 to restrict the movement of the conveyor frame 8 in the front-back direction. The positioning and locking mechanism 6 preferably adopts a clamping cylinder to clamp the structure suitable for gripping on the conveyor frame 8.

[0047] As an optional implementation, an L-shaped positioning mechanism 7 is also included. The L-shaped positioning mechanism 7 is connected to the maintenance and adjustment track 5. Preferably, there are two L-shaped positioning mechanisms 7, and the two L-shaped positioning mechanisms 7 are symmetrically arranged. The conveyor frame 8 is provided with positioning pulleys 81 that contact the L-shaped positioning mechanisms 7. Preferably, two positioning pulleys 81 are provided at the corresponding position of each L-shaped positioning mechanism 7, and the two positioning pulleys 81 are arranged at 90° to match the two connecting plates vertically connected to the L-shaped positioning mechanism 7. The L-shaped positioning mechanism 7 can restrict the movement of the conveyor frame 8 in the left and right directions.

[0048] In this embodiment, a Y-shaped variable track is preferably used to transfer the transfer frame 8 from the conventional track to the dedicated maintenance and adjustment track 5. After the transfer is completed, the positioning and locking mechanism 6 is used to fix the transfer frame 8, thereby effectively preventing the transfer frame 8 from sliding back and forth. The two L-shaped positioning mechanisms 7 on the track and the positioning pulleys 81 on the transfer frame 8 are used to fix the transfer frame 8 at a 90° angle, thereby effectively preventing the transfer frame 8 from swinging left and right and ensuring the accuracy of the transfer frame 8 during detection or adjustment.

[0049] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
