For example, the difference in width W between the two specifications can be 0.2 mm.
[0035] In embodiments of this application, the length direction, width direction, and height direction of the detection device 100 can be defined as a first direction, a second direction, and a vertical direction, respectively.

[0036] Please refer to the following: Figure 4 In one embodiment, the testing equipment 100 may include a machine base 10, a transmission device 20, a fixing device 30, and a testing device 40. The machine base 10 may be placed or fixedly installed on the ground.
[0037] The transmission device 20 may include a transmission mechanism 21 and a lifting mechanism 22. The transmission mechanism 21 may include a synchronous belt 211 and a pulley drive assembly 212. The pulley drive assembly 212 may include multiple pulleys and a bracket, with the pulleys rotatably connected to the bracket, and the bracket being fixedly mounted on the machine base 10. There may be two synchronous belts 211, spaced apart in a second direction. Each synchronous belt 211 may be wound around multiple pulleys. The pulley drive assembly 212 may also include a transmission drive component, which can drive the multiple pulleys to rotate, thereby driving the synchronous belt 211 to rotate. The top portion of the synchronous belt 211 can support the test piece 200, and the rotation of the synchronous belt 211 can drive the test piece 200 to move along a first direction, thereby achieving the transmission of the test piece 200.
[0038] The lifting mechanism 22 may include lifting wheels 221 and a lifting drive 222. There may be two lifting wheels 221, with each pair of lifting wheels 221 receiving the corresponding conveyor belt body located at the top from the bottom. The two lifting wheels 221 may be coaxial and connected to the lifting drive 222 via a connecting frame, allowing the two lifting wheels 221 to rotate relative to the connecting frame. The lifting drive 222 can drive the two lifting wheels 221 to move vertically, thereby lifting or lowering the synchronous belt 211 on which the test piece 200 is attached. Specifically, the lifting drive 222 can lift the top of the synchronous belt 211 to a first height and lower the belt body to a second height.
[0039] The fixing device 30 can be fixedly mounted on the machine tool 10 via a bracket, and the fixing device 30 can be located at the detection position. The detection position can be a preset position on the machine tool 10. The vertical projection of the fixing device 30 can coincide with the vertical projection of the two synchronous belts 211, and at least part of the fixing device 30 is located between the two synchronous belts 211. The top of the fixing device 30 can be located at a second height, and two clearance grooves 311 can be formed on the top of the fixing device 30. The two clearance grooves 311 are spaced apart in the second direction and both penetrate through both sides of the fixing device 30 in the first direction. The two clearance grooves 311 can respectively accommodate the belt body at the top of the two synchronous belts 211 when the belt body at the top of the two synchronous belts 211 is located at the second height. The top of the fixing device 30 can support the test piece 200 located at the second height.
[0040] The inspection device 40 can be fixedly mounted on the machine base 10 by a bracket, and at least a portion of the structure of the inspection device 40 is located above the inspection position. The inspection device 40 can inspect the part 201 located on the part 200 when the workpiece 200 is transferred to the inspection position and descends to the second height. By inspecting the width of the part to be inspected 202 on the part 201, the specific specifications of the part 201 are determined, thereby determining whether the part 201 adopts the correct specifications.
[0041] It is understood that the transmission drive component can be an electric or pneumatic component with rotational drive function. In the embodiments of this application, the type of transmission drive component is not specifically limited. For example, the transmission drive component can be, but is not limited to, a motor, a rotary cylinder, etc.
[0042] It is understood that the lifting drive component 222 can be an electric or pneumatic component with linear movement drive function. In the embodiments of this application, the type of the lifting drive component 222 is not specifically limited. For example, the lifting drive component 222 can be, but is not limited to, a linear motor, a cylinder, etc.
[0043] In the embodiments of this application, the fixing method during fixed connection and fixed installation is not specifically limited. For example, the fixing method may include, but is not limited to, bolt fixing, screw fixing, welding fixing, integral molding fixing, etc.
[0044] It is understood that the transmission device 20 can transmit the test piece 200 along a first direction and keep the test piece 200 at a first height. When the test piece 200 is transmitted to the detection position, the pulley drive assembly 212 can stop working, and the lifting drive 222 can drive the lifting wheel 221 to descend to a second height, thereby causing the belt body of the timing belt 211 at the top and the test piece 200 on the timing belt 211 to descend to the second height, so that the timing belt 211 enters the clearance groove 311, and the fixing device 30 receives the test piece 200. Then, the detection device 40 can detect the test piece 200 located on the fixing device 30 to detect the specifications of the part 201 on the test piece 200.
[0045] The testing device 100 may further include a processor (not shown), which can communicate with the testing device 40. The testing device 40 can output the testing results to the processor, which can confirm the testing results and generate a testing report.

[0046] It is understood that the communication connection can be a wired communication connection implemented through devices such as signal lines, or a wireless communication connection implemented through technologies such as 3G, 4G, 5G, Bluetooth, wireless local area network, and cellular network. The embodiments of this application do not limit this.
[0047] In the embodiments of this application, the type of monitoring device is not specifically limited. For example, the monitoring device may be, but is not limited to, personal computers, industrial computers, tablet computers, etc.
[0048] Please refer to the following: Figure 5 and Figure 6 In some embodiments, the detection device 40 may include a detection drive 41, a first floating mechanism 42, a second floating mechanism 43, and a connector 44.
[0049] The detection drive unit 41 can be fixedly mounted on the machine base 10 via a bracket. The first floating mechanism 42 may include a first base 421, a first floating seat 422, a first limiting seat 423, and a first elastic member 424. The first base 421 can be fixedly mounted on the mover of the detection drive unit 41. The first floating seat 422 can be located on one side of the first base 421 in a second direction. The first floating seat 422 can be movably connected to the first base 421 in a vertical direction. There can be two first limiting seats 423, which can be spaced apart in a vertical direction. Two second limiting seats 423 are fixedly mounted on the bottom and top of the first base 421, respectively. The distance between the two first limiting seats 423 is greater than the height of the first floating seat 422. The first floating seat 422 is confined between the two first limiting seats 423 and can move between the two first limiting seats 423. Each first limiting seat 423 can abut against the first floating seat 422 when the first floating seat 422 moves, thereby blocking the first floating seat 422 and limiting the movement distance of the first floating seat 422. The first elastic member 424 can abut against or be connected to the bottom of the first floating seat 422, and abut against or be connected to the top of the first limiting seat 423 located at the bottom. There can be multiple first elastic members 424, and the multiple first elastic members 424 can be spaced apart along a first direction and / or a second direction.
[0050] The second floating mechanism 43 may include a second base 431, a second floating seat 432, a second limiting seat 433, and a second elastic member 434. There may be two second bases 431, which may be spaced apart in a second direction. Both second bases 431 may be fixedly mounted on the bottom of the first floating seat 422. The second floating seat 432 may be located between the two second bases 431. The second floating seat 432 may be movably connected to the two second bases 431 along a first direction. The length of the second floating seat 432 in the first direction is greater than the length of the two bases in the first direction. There may be two second limiting seats 433, which may be spaced apart in the first direction. The two second limiting seats 433 are respectively fixedly connected to both sides of the second floating seat 432 in the first direction. Each second limiting seat 433 may abut against the second base 431 when the second floating seat 432 moves, thereby limiting the movement distance of the second floating seat 432. Multiple second elastic members 434 may be provided on one side of each second limiting seat 433 facing another second limiting seat 433. Multiple second limiting seats 433 located on the same side in the first direction may be spaced apart along the vertical direction and / or the second horizontal direction. Each second elastic member 434 may abut or connect to the corresponding second base 431 and abut or connect to the corresponding second limiting seat 433.
[0051] Please refer to the following: Figure 7 and Figure 8 The connector 44 can be fixedly installed at the bottom of the second floating seat 432. The width of the connector 44 in the second direction can be greater than the width of the connector 44. A mating groove 441 can be formed at the bottom of the connector 44. The distance between the two side walls of the mating groove 441 in the first direction can be greater than or equal to the width of the part to be tested 202 on the first specification part 201, and less than the width of the part to be tested 202 on the second specification part 201. The mating groove 441 can accommodate the part to be tested 202 on the first specification part 201. A guide surface 442 is formed at the connection between the bottom of the connector 44 and the side wall of the mating groove 441. The guide surface 442 is an arc surface or a slope surface. The guide surface 442 can abut against the part to be tested 202 and guide the part to be tested 202 into the mating groove 441.
[0052] It is understood that the detection driver 41 can communicate with the processor, and the processor can control the operation of the detection driver 41.
[0053] Part 201 can be mounted on top of the test piece 200. When the test piece 200 is in the detection position, the connector 44 can be positioned above part 201 on the test piece 200. When the detection device 40 detects the specifications of part 201, the detection drive 41 can drive the first base 421 to descend a preset distance, which can be equal to or less than the distance between the bottom of the connector 44 and the top of the test piece 200.
[0054] When part 201 is of the first specification, when the connector 44 approaches the part to be tested 202, the part to be tested 202 can be completely inserted into the mating groove 441. At this time, the connector 44 is not subjected to an upward driving force in the vertical direction, so the first floating seat 422 and the first base 421 remain relatively stationary. By determining that the first floating seat 422 does not move upward relative to the first base 421, it can be determined that the specification of part 201 detected by the detection device 40 is the first specification.
[0055] When the specification of part 201 is not the first specification, the width of the test portion 202 of part 201 is greater than the width of the test portion 202 on part 201 of the first specification. When the connector 44 approaches the test portion 202, the test portion 202 cannot enter the mating groove 441. The test portion 202 abuts against the bottom of the connector 44 and blocks the descent of the connector 44, causing the connector 44 to move upward relative to the first base 421, and causing the first floating seat 422 to move upward relative to the first base 421; the first elastic member 424 can buffer the movement of the first floating seat 422. By determining that the first floating seat 422 moves upward relative to the first base 421, it can be determined that the specification of part 201 detected by the detection device 40 is a specification other than the first specification, such as the second specification.
[0056] After the part 201 is inspected, the inspection drive 41 can drive the connector 44 to rise and move away from the part 201. The first floating seat 422, which has moved upward relative to the first base 421, can move downward relative to the first base 421 under the action of gravity and the elastic force of the first elastic member 424, and abut against the first limiting seat 423 located at the bottom.
[0057] It is understandable that, due to potential deviations in the installation position of part 201 during production compared to the preset position, there may be a deviation between the tested portion 202 and the mating groove 441 when the test part 200 is in the detection position. When a deviation exists between the tested portion 202 and the mating groove 441, the guide surface 442 can abut against the tested portion 202 as the connector 44 descends, guiding the connector 44 to move relative to the tested portion 202. The connector 44 can float synchronously with the second floating seat 432 in the first direction, and the second elastic element 434 can cushion the movement of the second floating seat 432.
[0058] After the part 201 is inspected, the inspection drive 41 can drive the connector 44 to rise and move away from the part 201. The second floating seat 432 can return to its initial position under the elastic force of the second elastic members 434 on both sides, so that the second base 431 is located in the middle position between the two second limit seats 433 in the first direction.
[0059] In the embodiments of this application, the types of the first elastic element 424 and the second elastic element 434 are not specifically limited. For example, both the first elastic element 424 and the second elastic element 434 can be, but are not limited to, springs.
[0060] In the embodiments of this application, the type of detection drive 41 is not specifically limited. For example, the detection drive 41 may be, but is not limited to, a linear motor, a cylinder, etc.
[0061] In some embodiments, the detection device 40 may further include a detection mechanism 45. The detection mechanism 45 can detect the upward movement of the first floating seat 422 relative to the first base 421. When the detection device 40 detects the specifications of the part 201, by determining whether the first floating seat 422 rises relative to the first base 421, it can determine whether the connector 44 is lifted by the part to be tested 202, thereby determining whether the part 201 is of the first specification.
[0062] The detection mechanism 45 may include a detection head 451 and a movable detection element 452. The detection head 451 may be fixedly mounted on a first floating seat 422 and located on one side of the first floating seat 422 in a first direction. The top of the first floating seat 422 protrudes from the top of the first floating seat 422. The movable detection element 452 may be fixedly mounted on a first base 421 or a first limiting seat 423 located at the top, so as to be fixed relative to the first base 421. The movable detection element 452 may be located on the same side of the detection head 451 in the first direction.
[0063] When the first floating seat 422 rises relative to the first base 421, the detection head 451 can move synchronously. As the detection head 451 moves upward, it enters the detection area of the moving detection element 452, allowing the moving detection element 452 to detect the rise of the detection head 451. The moving detection element 452 can communicate with the processor, outputting the detection result to the processor. The processor can determine from the detection result whether the detection head 451 has risen, thus determining that the detected part 201 is not of the first specification; alternatively, the processor can determine from the detection result that the detection head 451 has not risen, thus determining that the detected part 201 is of the first specification.
[0064] In the embodiments of this application, the type of motion detection element 452 is not specifically limited. For example, the motion detection element 452 may be, but is not limited to, an infrared sensor, a photoelectric sensor, a proximity switch, etc.
[0065] Please refer to the following: Figure 9 and Figure 10 In some embodiments, the fixing device 30 may include a receiving platform 31, a first fixing mechanism 32, and a second fixing mechanism 33.
[0066] The receiving platform 31 is vertically spaced from the machine base 10 and located above the machine base 10. The receiving platform 31 can be fixedly mounted on the machine base 10 using a bracket. The receiving platform 31 is located at the detection position, and its top surface is in a second position. The receiving platform 31 can receive the test piece 200 descending from a first height to a second height. Two clearance slots 311 can be formed on the top of the receiving platform 31. Multiple suction cups 312 can also be fixedly connected to the receiving platform 31, with all suction cups 312 protruding from the top of the receiving platform 31. The multiple suction cups 312 can adsorb the test piece 200 using negative pressure.
[0067] The first fixing mechanism 32 may include a first driving member 321, a linkage assembly, and two first abutting members 322. The first driving member 321 may be fixedly installed at the bottom of the receiving platform 31. The linkage assembly may be located at the bottom of the receiving platform 31. The linkage assembly may include a first moving member 323, two connecting rods 324, and two second moving members 325. The first moving member 323 may be movably connected to the receiving platform 31 in a second direction and is fixedly connected to the first driving member 321. The two second moving members 325 are respectively located on both sides of the first moving member 323 in a first direction, and both second moving members 325 are movably connected to the receiving platform 31 in the first direction. The two second connecting rods 324 correspond one-to-one with the two second moving members 325. One end of each second connecting rod 324 is rotatably connected to the corresponding second moving member 325, and the other end is rotatably connected to the first moving member 323. The connection points of the two second links 324 on the first moving member 323 are both located on the side of the first moving member 323 facing away from the first driving member 321 in the second direction. The first driving member 321 can drive the first moving member 323 to move in the second direction, causing the two links 324 to rotate; the rotation of each link 324 can drive the corresponding second moving member 325 to move in the first direction. When the first moving member 323 moves, it can drive the two second moving members 325 to move closer or further apart. Two first abutting members 322 correspond to the two second moving members 325 respectively. Each first abutting member 322 can be fixedly installed on the corresponding second moving member 325 by a bracket, and the height of the first abutting member 322 is greater than the height of the second moving member 325. The two first abutting members 322 can move closer or further apart under the drive of the first driving member 321; when the two first driving members 321 move closer together, they can respectively abut against the two sides of the test piece 200 in the first direction to clamp and fix the test piece 200.
[0068] The second fixing mechanism 33 may include a second driving member 331, a second abutting member 332, and a third abutting member 333. The second driving member 331 can be fixedly mounted on the machine base 10 via a bracket. The second abutting member 332 can be fixedly mounted on the top of the receiving platform 31 and located on the first side of the receiving platform 31 in the second direction. There may be multiple second abutting members 332, which may be spaced apart in the first direction, and each second abutting member 332 may abut against the test piece 200 on the first side in the second direction. The third abutting member 333 may be located on the second side of the receiving platform 31 in the second direction. The third abutting member 333 may include an abutting wheel 3332 and a connecting seat 3331. The connecting seat 3331 may be fixedly connected to the second driving member 331. There may be multiple abutting wheels 3332, which may be spaced apart in the first direction, and each of the multiple abutting wheels 3332 may be rotatably connected to the top of the connecting seat 3331. The arc surfaces of multiple abutting wheels 3332 protrude from the side of the connecting seat 3331 facing the second abutting member 332. The second driving member 331 can drive the connecting seat 3331 to move in the second direction, so that the multiple abutting wheels 3332 approach or move away from the test piece 200 on the receiving platform 31; when the second driving member 331 drives the multiple abutting wheels 3332 to approach the test piece 200, the multiple abutting wheels 3332 can abut against the second side of the test piece 200 in the second direction, and cooperate with the multiple third abutting members 333 to clamp and fix the test piece 200.
[0069] It is understandable that the second direction can have a first side and a second side that are set relative to each other.
[0070] In the embodiments of this application, the types of the first driving member 321 and the second driving member 331 are not specifically limited. For example, both the first driving member 321 and the second driving member 331 can be, but are not limited to, linear motors, cylinders, etc.
[0071] It is understood that a movable connection can be achieved through a movable connector, allowing two components to move relative to each other in a linear direction. In the embodiments of this application, the type of movable connector is not specifically limited. For example, the movable connector can be, but is not limited to, a linear guide rail.
[0072] It is understood that a rotatable connection can be achieved through a rotating connector, allowing two components to rotate relative to each other. In the embodiments of this application, the type of rotating connector is not specifically limited. For example, a rotating connector can be, but is not limited to, bearings, pins, hinges, etc.
[0073] It is understandable that when the test piece 200 moves to the detection position, it can descend to a second height, and then the suction cup 312 can adsorb the test piece 200. The two first abutment members 322 can clamp the test piece 200 from the first direction, and the second abutment member 332 and the third abutment member 333 cooperate to clamp the test piece 200 from the second direction. In this way, the fixing device 30 can fix the test piece 200, thereby avoiding the movement of the test piece 200 on the receiving platform 31 caused by the contact between the part 201 and the connector 44 when the detection device 40 detects the specifications of the part 201. This avoids the movement of the test piece 200 affecting the detection results and prevents the test piece 200 from falling off the receiving platform 31 and being damaged.
[0074] It is understood that the suction cup 312, the first driving member 321, and the second driving member 331 can be communicatively connected to the processor. After the detection device 40 completes the detection of the part 201, the processor can control the suction cup 312, the first driving member 321, and the second driving member 331 to operate, causing the two first abutting members 322 to move away from the part under test 200, causing the third abutting member 333 to move away from the part under test 200, and releasing the suction cup 312 from the part under test 200. Then the processor can control the lifting driving member 222 to operate, causing the belt body of the synchronous belt 211 at the top to be lifted, thereby driving the part under test 200 to return from the second height to the first height; then the processor can control the transmission driving member to operate, thereby causing the part under test 200 to continue to be transmitted, and causing the part under test 200 that has not been detected to be transmitted to the detection position.
[0075] Please refer to the following: Figure 11 In some embodiments, the detection device 100 may further include a blocking device 50. The blocking device 50 may be located between two synchronous belts 211. The blocking device 50 may include a blocking drive 51, a blocking member 52, and a position detection member 53.
[0076] The blocking drive member 51 can be fixedly mounted on the machine base 10 via a bracket. The blocking member 52 can be fixedly connected to the blocking drive member 51, and the blocking drive member 51 can drive the blocking member 52 to move vertically. In the transmission direction of the transmission mechanism 21, the blocking member 52 can be located on one side of the detection position. The blocking drive member 51 can drive the blocking member 52 to move vertically. When the blocking member 52 is at the first height, the blocking member 52 can block the device under test 200 in transmission; when the blocking drive member 51 drives the blocking member 52 to descend, the blocking member 52 releases its obstruction of the device under test 200 at the first height, and the transmission mechanism 21 can drive the device under test 200 to continue transmission.
[0077] The position detection element 53 can be fixedly installed on the side of the blocking element 52 facing the detection position. The position detection element 53 can determine whether the test piece 200 has entered the detection position by detecting whether the test piece 200 has entered the detection area of the position detection element 53.
[0078] It is understood that the blocking drive 51 and the position detection 53 can be communicatively connected to the processor. When the position detection 53 detects that the test piece 200 has entered the detection position, it can output the detection result to the processor. After receiving the detection result from the position detection 53, the processor can control the transmission drive to stop working and drive the lifting drive 222 to work so that the test piece 200 can be lowered to the second height. Then, the detection device 40 and the fixing device 30 can work to realize the detection of the specifications of the part 201.
[0079] After the inspection of part 201 is completed, the test piece 200 rises to the first height. The processor can control the blocking drive 51 to operate, causing the blocking member 52 to descend and release the obstruction of the test piece 200. Then, the processor can control the transmission drive to operate, allowing the test piece 200 to continue transmission. When the test piece 200 moves out of the inspection position, the processor can control the blocking drive 51 to operate, causing the blocking member 52 to rise to the first height, so as to obstruct the test piece 200 to be inspected again.
[0080] In the embodiments of this application, the type of position detection element 53 is not specifically limited. For example, the test object 200 can be made of metal, and the position detection element 53 can be a metal proximity switch.
[0081] In the embodiments of this application, the type of blocking drive member 51 is not specifically limited. For example, the blocking drive member 51 may be, but is not limited to, a cylinder, a linear motor, etc.
[0082] In the embodiments of this application, the number of the detection device 40, the transmission device 20, the fixing device 30, and the blocking device 50 is not specifically limited. For example, there can be multiple transmission devices 20, which can be spaced apart on the machine tool 10 in the second direction. Each transmission device 20 can transmit at least one workpiece 200 to be tested. Each transmission device 20 can be correspondingly provided with at least one detection device 40, fixing device 30, and blocking device 50. In this way, the workpiece 200 transmitted by each transmission device 20 can be tested according to the specifications of the part 201 through the corresponding detection device 40, fixing device 30, and blocking device 50.
[0083] It is understood that the number of parts 201 on each test piece 200 can be one or more. When the number of parts 201 on each test piece 200 is multiple, each transmission device 20 can be equipped with multiple detection devices 40, and the multiple detection devices 40 can simultaneously detect the specifications of multiple parts 201.
[0084] In the testing device 100 provided in the embodiments of this application, the test piece 200 can be moved to the testing position by the transmission device 20. Then, the lifting mechanism 22 operates to lower the test piece 200 from a first height to a second height and place it on the receiving platform 31. Then, the first fixing mechanism 32 and the second fixing mechanism 33 cooperate to fix the test piece 200 in the first and second directions. Then, the testing device 40 can determine whether the specification of the part 201 is the first specification by observing whether the first floating seat 422 rises relative to the first base 421 when the connector 44 approaches the part 201. Then, the connector 44 can move away from the part 201, the first fixing mechanism 32 and the second fixing mechanism 33 can release the fixation of the test piece 200, the lifting structure can raise the test piece 200 to the first height, the blocking drive member 51 can lower the blocking member 52 to release the obstruction of the test piece 200, and then the transmission mechanism 21 can continue to transmit the test piece 200 after testing.
[0085] Thus, by checking whether the first floating seat 422 rises, it can be determined whether the part to be tested 202 can enter the docking groove 441, thereby determining whether the part 201 is of the first specification. The testing equipment 100 provided in the embodiments of this application can automatically test the specifications of the part 201 on the test piece 200. Furthermore, by determining whether the first floating seat 422 moves, it is possible to directly determine whether the part 201 is of the first specification. This reduces the probability of errors in the specifications of the part 201 installed on the test piece 200 going undetected, improves the convenience for workers to inspect the specifications of the part 201, and increases the product yield rate.
[0086] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments described above should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application.
