For those of ordinary skill in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0055] Please refer to Figure 1 The product detection device provided in the embodiments of the present application comprises a rack 10, a first detection mechanism 20, a second detection mechanism 30 and a conveying line 100.

[0056] The conveying line 100 is used for conveying products. The rack 10 is erected on the conveying line 100. The first detection mechanism 20 and the second detection mechanism 30 are arranged on the rack 10, and the first detection mechanism 20 and the second detection mechanism 30 can be moved to a detection state or a misaligned state on the rack 10.

[0057] In the misaligned state, please refer to Figure 2 The first detection mechanism 20 and the second detection mechanism 30 are misaligned with the conveying track of the products on the conveying line 100.

[0058] In the embodiment, the first detection mechanism 20 and the second detection mechanism 30 are in the dislocation state during the product transportation, so that the first detection mechanism 20 and the second detection mechanism 30 are dislocated with the conveying track of the product on the conveying line 100, that is, the first detection mechanism 20 and the second detection mechanism 30 do not interfere with the conveying of the product at this time, so that the product conveyed by the conveying line 100 can pass through the rack 10.

[0059] In the detection state, referring to Figure 1 and Figure 3 , the first detection mechanism 20 and the second detection mechanism 30 are oppositely arranged, and the first detection mechanism 20 and the second detection mechanism 30 are respectively located at two ends of the product on the conveying line 100. That is, during the switching from the dislocation state to the detection state, the conveying line 100 stops running, so that the product stays in the rack 10, and then the first detection mechanism 20 and the second detection mechanism 30 gradually move towards the product until the first detection mechanism 20 and the second detection mechanism 30 are in the detection state. In the detection state, the first detection mechanism 20 and the second detection mechanism 30 are respectively aligned with the two ends of the product, so that the product can be directly detected. After detection, the first detection mechanism 20 and the second detection mechanism 30 move to the dislocation state, and the next product to be detected is conveyed into the rack 10 to realize continuous detection.

[0060] In the embodiment, the first detection mechanism 20 and the second detection mechanism 30 can directly act on the product on the conveying line 100, without the need to transfer the product between the detection platform outside the conveying line 100 and the conveying line, which can reduce the vibration of the product during the transfer process, avoid the deviation of the internal components of the product, and at the same time, can realize the effects of occupying less space, simplifying the equipment, improving the detection efficiency, and improving the space utilization.

[0061] In one embodiment, the device further comprises a jacking mechanism 40, which is arranged below the conveying line 100 and is used to jack up the product in the detection state.

[0062] Specifically, the jacking mechanism 40 can include a liftable jacking table. In the dislocation state, the jacking table is lowered below the conveying line 100, so that the product can pass above the jacking mechanism 40. In the detection state, the conveying line 100 stops running, so that the product stays above the jacking table, and then the jacking table is raised to fix the product. During the detection process, the jacking table can support the product. At the same time, by arranging the jacking mechanism 40, the detection stations of the first detection mechanism 20 and the second detection mechanism 30 can be located above the conveying line 100, avoiding the interference of the first detection mechanism 20 and the second detection mechanism 30 with the conveying line 100.

[0063] In actual application, the product can be placed on a tray, that is, the conveying line 100 is used to convey the product on the tray. When the lifting platform is lifted, the tray can be lifted.

[0064] In a more specific embodiment, referring to Figure 1 and Figure 4 , the device further comprises a pressing mechanism 50; the pressing mechanism 50 comprises a pressing claw 51; the pressing claw 51 is arranged on the frame 10 in a lifting manner, and the pressing claw 51 is located above the lifting mechanism 40; the pressing claw 51 is used to press the product on the lifting mechanism 40.

[0065] In the detection state, the pressing claw 51 can be lowered to press the product on the lifting mechanism 40, so as to ensure the stability of the product during the detection. After detection, the pressing claw 51 is lifted and separated from the product.

[0066] As a further improvement, the pressing claw 51 is provided with a plurality of pressing columns 52 with adjustable length. The pressing columns 52 are used to abut against the product. The adjustable length of the plurality of pressing columns 52 enables the pressing claw 51 to adapt to products of different shapes and sizes.

[0067] In a more specific embodiment, the product is an electric drive; the first detection mechanism 20 and the second detection mechanism 30 are used to detect the starting torque of the product. To this end, during detection, the first detection mechanism 20 and the second detection mechanism 30 need to be located in the axial direction of the product, so that they can drive the shaft on the product to rotate for torque measurement.

[0068] In this embodiment, in the detection state, the first detection mechanism 20 and the second detection mechanism 30 are located at both ends of the axial direction of the product.

[0069] On the basis of the above-mentioned embodiments, as an implementation, referring to Figure 5 , during conveying, the axial direction of the product is parallel to the conveying direction of the conveying line 100; the first detection mechanism 20 and the second detection mechanism 30 are arranged on both sides of the conveying line 100 along the width direction of the conveying line 100; the lifting mechanism 40 is provided with a rotating table; after the lifting mechanism 40 lifts the product, the rotating table drives the product to rotate.

[0070] For ease of illustration, in the embodiments of the present application, referring to Figures 1 to 3 and Figure 5 , the conveying direction of the conveying line 100 is parallel to the length direction thereof, which is the x-axis direction in the figure; the width direction of the conveying line 100 is perpendicular to the conveying direction thereof, which is the y-axis direction in the figure.

[0071] Since the first detection mechanism 20 and the second detection mechanism 30 are arranged in the width direction of the conveying line 100, the first detection mechanism 20 and the second detection mechanism 30 can be kept in the misaligned state, and the product can directly pass between the first detection mechanism 20 and the second detection mechanism 30. When the product to be detected is stopped between the first detection mechanism 20 and the second detection mechanism, the detection state is further achieved.

[0072] In actual application, due to the requirements of the previous process, the product placement requirements, and the space limitations, the product needs to be placed in the axial direction parallel to the conveying direction of the conveying line 100, and thus, when the product is stopped between the first detection mechanism 20 and the second detection mechanism, the first detection mechanism 20 and the second detection mechanism are not directed to the axial direction of the product. Therefore, in the embodiment, the product can be lifted and rotated by the jacking mechanism 40, so that the first detection mechanism 20 and the second detection mechanism can be aligned with the axial direction of the product to detect the starting torque.

[0073] In another embodiment provided in the application, referring to Figures 1 to 3 , the axial direction of the product is parallel to the conveying direction of the conveying line 100 during the conveying process, and the first detection mechanism 20 and the second detection mechanism 30 are arranged along the conveying direction of the conveying line 100.

[0074] Specifically, although the first detection mechanism 20 and the second detection mechanism are arranged in the width direction of the conveying line 100 to keep the equipment in the misaligned state, due to the poor control accuracy of the conveying line 100, when the conveying line 100 is stopped, the product generally cannot be accurately stopped between the first detection mechanism 20 and the second detection mechanism, and thus the first detection mechanism 20 and the second detection mechanism need to be fine-tuned according to the position of the product after the product is rotated.

[0075] In the embodiment, since the first detection mechanism 20 and the second detection mechanism are arranged along the conveying direction of the conveying line 100, the above situation can be avoided, and the alignment accuracy of the first detection mechanism 20 and the second detection mechanism with the product can be improved. For example, the product can be directly placed in the specified area of the conveying line 100 during the conveying process, and a stroke limiter is arranged on the rack, and when the first detection mechanism 20 and the second detection mechanism are moved along the y-axis direction to abut against the stroke limiter, the first detection mechanism 20 and the second detection mechanism are aligned with the axial direction of the product.

[0076] In general, the embodiment can reduce the difficulty of aligning the first detection mechanism 20 and the second detection mechanism with the product, improve the alignment accuracy and efficiency of the first detection mechanism 20 and the second detection mechanism with the product, and achieve rapid alignment and rapid detection.

[0077] In one embodiment, referring to Figure 1 and Figure 6The air-avoiding mechanism 60 comprises a first sliding rail 61 and a first driving member 63, and / or a second driving member 64 and a second sliding rail 62. In the example provided in the embodiment, the air-avoiding mechanism 60 comprises the first sliding rail 61, the first driving member 63, the second driving member 64 and the second sliding rail 62.

[0078] Specifically, the first sliding rail 61 and the second sliding rail 62 are arranged on the rack 10, and the length direction of the first sliding rail 61 and the second sliding rail 62 is the width direction of the conveying line 100; the first detection mechanism 20 and the second detection mechanism 30 are arranged on the first sliding rail 61 and the second sliding rail 62 respectively; the output end of the first driving member 63 is connected with the first detection mechanism 20, for driving the first detection mechanism 20 to slide along the first sliding rail 61; the output end of the second driving member 64 is connected with the second detection mechanism 30, for driving the first detection mechanism 20 to slide along the second sliding rail 62.

[0079] In the embodiment, the length direction of the first sliding rail 61 and the second sliding rail 61 is the y-axis direction. The first sliding rail 61 and the second sliding rail 61 can play the role of stroke limiting and guiding for the first detection mechanism 20 and the second detection mechanism 30. During actual detection, the relative position adjustment between the first detection mechanism 20, the second detection mechanism 30 and the product can be realized in a fixed track, and the first detection mechanism 20 and the second detection mechanism 30 can realize direct docking detection along the track direction without adjusting the direction. In the embodiment, the first driving member 63 and the second driving member 64 can be, for example, rotary motors, linear motors and air cylinders.

[0080] Further, the first detection mechanism 20 and the second detection mechanism 30 are arranged to move synchronously, so that the first detection mechanism 20 and the second detection mechanism 30 can keep the relative state, and the problem of inconsistent axial alignment of the first detection mechanism 20, the second detection mechanism 30 and the product can be avoided, the control difficulty of the alignment of the first detection mechanism 20, the second detection mechanism 30 and the product is reduced, and the rapid detection is facilitated.

[0081] It should be noted that the control mode of synchronous movement of the first detection mechanism 20 and the second detection mechanism 30 can adopt the prior art, for example, the synchronous start-stop connection of the two through transmission components, or the synchronous control of the start-stop of the first driving member 63 and the second driving member 64 through a control system.

[0082] In one embodiment, the first detection mechanism 20 and the second detection mechanism 30 can have consistent structures. Please refer to Figure 7The second detecting mechanism 30 and / or the first detecting mechanism 20 comprises a positioning drive 22, a test assembly 23 and a position sensor 24. The test assembly 23 is movably arranged along the conveying direction of the conveying line 100, and specifically, the test assembly 23 is movable in the positive and negative directions of the conveying direction of the conveying line 100. The output end of the positioning drive 22 is connected to the test assembly 23, and is used to drive the test assembly 23 to move along the conveying direction of the conveying line 100. The position sensor 24 is arranged on the test assembly 23, and is electrically connected to the positioning drive 22, and is used to sense the distance between the test assembly 23 and the product. After the position sensor 24 senses that the test assembly 23 is docked with the product, the positioning drive 22 is controlled to stop.

[0083] In the embodiment, after the first detecting mechanism 20 and the second detecting mechanism 30 are aligned with the axial direction of the product, the positioning drive 22 can drive the test assembly 23 to move along the axial direction of the product, and finally abut against the product.

[0084] In actual application, the second detecting mechanism 30 and / or the first detecting mechanism 20 can further comprise a support 21. The support 21 is movably arranged on the rack 10 along the width direction of the conveying line 100. The positioning drive 22 and the test assembly 23 are arranged on the support 21.

[0085] As an implementation manner, the test assembly 23 comprises a test driver 25 and a test head 26. The test head 26 can be connected to the rotating shaft of the product. The test driver 25 can drive the test head 26 to rotate, so as to drive the test head 26 to rotate and detect the product.

[0086] The above is the preferred embodiment of the present application, and is not used to limit the present application. Although the present application is described in detail with reference to the examples, those skilled in the art can still modify the technical solutions recorded in the foregoing examples, or equivalently replace some of the technical features, but any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
