[0037] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0038] The present application provides a detection device for use in appearance detection of an antenna 400. Figure 1 The detection device includes a bracket 100, a clamping assembly 200, a detection assembly 300 and a control assembly (not shown in the figure). One end of the clamping assembly 200 is connected to the bracket 100. The clamping assembly 200 clamps the antenna 400 to be detected, and drives the antenna 400 to move to the detection area of ​​the detection assembly 300 to detect whether the antenna 400 is a qualified product, and stores the corresponding area where the antenna 400 is placed according to whether the product is qualified.

[0039] Reference Figure 2The antenna 400 is a snap-fit ​​antenna, which has an upper cover 410 and a lower cover 420 that are pressed and fastened to each other, and the upper cover 410 and the lower cover 420 form the top surface and the bottom surface of the antenna 400. When inspecting the appearance of the antenna 400, the detection device mainly detects whether the snap-fit ​​surface of the antenna 400 (the snap-fit ​​surface refers to the surface where the upper cover 410 and the lower cover 420 are snap-fitted to each other) is poorly pressed. If there is a poor pressing problem, it is generally divided into three categories: the head 430 of the antenna 400 is tilted, the middle 440 of the antenna 400 is tilted, and the tail 450 of the antenna 400 is tilted.

[0040] Reference Figure 3 , the bracket 100 refers to a supporting component used to provide a moving position and a fixed position for the clamping assembly 200 and the detection assembly 300. The bracket 100 can be in an "I" shape, or a "U" shape in cross section, and the specific shape is not limited here. The bracket 100 has a base 110 and a top plate 120 that are relatively arranged. The base 110 and the top plate 120 are connected by a plate or a plurality of rods. The base 110 refers to a support seat of the bracket 100, and the top plate 120 refers to a component used to connect the clamping assembly 200, so that the clamping assembly 200 can move on the top plate 120 along the length direction of the top plate 120, so as to drive the antenna 400 to move from the loading area to the detection area, and complete the unloading.

[0041] The clamping assembly 200 refers to an assembly used to clamp and drive the antenna 400 to move between the loading area, the detection area and the unloading area.

[0042] Reference Figure 1 The clamping assembly 200 includes a first power member 210, a second power member 220 and a clamping member 230. The clamping member 230 refers to a component used to clamp the antenna 400, which can be one group or multiple groups, and each group includes two clamping plates arranged opposite to each other. The second power member 220 refers to a power member used to drive the clamping member 230 to move along the second direction Y to clamp the antenna 400. The second direction Y refers to the pointing direction along the illustrated position, and movement along the arrow direction is defined as rightward, and movement away from the arrow direction is defined as leftward. The first power member 210 refers to a power member used to drive the second power member 220 to move up and down along the first direction X. The first direction X refers to the pointing direction along the illustrated position, and movement along the arrow direction is defined as upward, and movement away from the arrow direction is defined as downward. The first power member 210 is connected to the top plate 120 via a coupling member 211.

[0043] Preferably, a guide rail 121 is provided on the top plate 120 , and the engaging member 211 of the first power member 210 can move along the guide rail 121 to drive the antenna 400 to move between the loading area, the detection area and the unloading area.

[0044] The detection component 300 is a component used to detect whether the buckle surface of the antenna 400 is poorly pressed.

[0045] Reference Figure 1 , the detection component 300 includes a first light source 310, a second light source 320 and a camera 330, wherein the first light source 310 and the second light source 320 refer to components for providing detection environment light, and the camera 330 refers to a component for visual detection of the antenna 400. Among them, the first light source 310 is connected to the top plate 120 through the first connecting rod 340, and is arranged on the opposite side of the camera 330, and the first light source 310 is arranged at an acute angle to the horizontal plane. The first light source 310 is suitable for highlighting the characteristics of the buckle surface of the antenna 400 to be detected. When the camera 330 takes a photo, the light is irradiated on the buckle surface of the antenna 400 to be detected. The second light source 320 and the camera 330 are both connected to the base 110 through the second connecting rod 350, and the second light source 320 and the camera 330 are oriented in the same direction and parallel to the horizontal plane. Among them, the camera 330 is arranged above the second light source 320. The second light source 320 is used to fill the tail 450 of the antenna 400 to be detected, and the auxiliary algorithm software matches the target object to be detected.

[0046] If the buckle surface is qualified, the light will not be refracted into the camera 330 and the image brightness will be normal.

[0047] If the head portion 430 or the middle portion 440 of the buckle surface is tilted, part of the light will be refracted into the lens of the camera 330, which will increase the brightness of the image.

[0048] If the tail portion 450 of the buckle surface of the antenna 400 is tilted, the light will be blocked and the image brightness will decrease.

[0049] The detection area refers to the area between the first light source 310 and the second light source 320 . The antenna 400 to be detected is placed in the detection area and detected by the detection component 300 .

[0050] It should be noted that when the detection component 300 performs appearance inspection on the antenna 400, the second power member 220 drives the clamping member 230 to clamp the antenna 400, and then the first power member 210 drives the second power member 220 to move the antenna 400 along the first direction X, so that the bottom of the antenna 400 is coplanar with the central axis of the camera 330.

[0051] If the number of antennas 400 to be detected is greater than two, multiple cameras 330 may be provided accordingly. For example, the number of antennas 400 to be detected is four, the number of cameras 330 is two, and the cameras 330 are placed along the second direction Y. During detection, one camera 330 detects the two antennas 400 to be detected on the left, and another camera 330 detects the two antennas 400 to be detected on the right.

[0052] Preferably, the angle between the first light source 310 and the horizontal plane is in the range of 30° to 45°, so that when the central axis of the camera 330 and the bottom of the antenna 400 are coplanar, the light from the first light source 310 can illuminate the bottom of the antenna 400, thereby detecting whether the snap-fit ​​surface of the antenna 400 is poorly pressed, thereby determining whether the antenna 400 is a qualified product.

[0053] The control component refers to a component of the detection device that controls when each component moves / stops moving. In the present embodiment, the control component is electrically connected to the first power member 210, the second power member 220, the clamping member 230 and the camera 330, respectively. The control component can control the second power member 220 to drive the clamping member 230 to move along the second direction Y to clamp the antenna 400. The control component can control the first power member 210 to drive the second power member 220 to move along the first direction X to descend to the bottom of the antenna 400 and be coplanar with the central axis of the camera 330. The control component can trigger the camera 330 to capture images and perform visual inspection to determine whether the antenna 400 to be inspected is a qualified component. Among them, the control component is preferably a PLC controller. For the sake of convenience, the following control component uses the PLC controller as an example to explain the connection relationship between the various components, but it does not mean that the control component is limited to the PLC controller.

[0054] The second power member 220 is controlled by the PLC controller to drive the clamping member 230 to move to clamp the antenna 400. Then, the clamping assembly 200 is moved with the antenna 400 to be inspected along the guide rail 121 to the inspection area (between the first light source 310 and the second light source 320) in a manual / automatic manner. Then, the first power member 210 is controlled by the PLC controller to drive the second power member 220 and the antenna 400 to be inspected to move to the bottom of the antenna 400 and the central axis of the camera 330. Then, the PLC controller is used to control the triggering signal of the camera 330 to perform visual inspection. After the inspection is completed, a product qualified or unqualified signal is issued. Finally, the clamping assembly 200 is moved with the antenna 400 to be inspected along the guide rail 121 to the unloading area corresponding to the qualified product and the unqualified product.

[0055] The technical solution adopted in this embodiment has the following technical effects compared with the prior art: the first light source 310 is set at an angle relative to the horizontal plane to highlight the features of the buckle surface of the antenna 400 to be detected, so that when taking pictures, the light is irradiated on the buckle surface of the antenna 400 to be detected. When the second light source 320 is used to fill light from the tail 450 of the antenna 400, the auxiliary algorithm software matches the detection, so as to judge whether the antenna 400 to be detected is a qualified product according to the brightness change of the image.

[0056] In one embodiment provided in this application, refer to Figure 4The first power member 210 includes a first driver 212 and a first slider 213 connected to the first driver 212. The first driver 212 can be electrically driven, electrically driven, or hydraulically driven, which is not specifically limited here. The first slider 213 is connected to the output end of the first driver 212, and the first driver 212 drives the first slider 213 to move up and down along the first direction X, so as to drive the second power member 220 and the antenna 400 to be detected to move up and down along the first direction X.

[0057] Preferably, the first driver 212 is hydraulically driven.

[0058] Reference Figure 1 A platform 111 is provided on the base 110. When there are multiple antennas 400 to be detected, the platform 111 is used to align multiple antennas 400 to be detected at one time so that each antenna 400 is on the same horizontal plane.

[0059] The clamping assembly 200 further includes a pressing member 240 , which is a component used to simultaneously press a plurality of antennas 400 to be tested so that the bottoms of the plurality of antennas 400 are all in the same plane.

[0060] The pressing member 240 includes a connecting plate 241 , a pressing plate 242 , and a spring assembly 243 that joins the connecting plate 241 and the pressing plate 242 .

[0061] Reference Figure 5 One end of the connecting plate 241 is connected to the first slider 213 and the second power member 220, and the other end of the connecting plate 241 is connected to the pressing plate 242. The connecting plate 241 is provided with a plurality of first through slots 241a and a plurality of first through holes 241b. The first through slots 241a are used to place the spring groups 243, and each first through slot 241a is used to place a group of spring groups 243.

[0062] The pressing plate 242 is used to press the antenna 400 to be tested. Each pressing plate 242 is provided with two second through holes 242a, a blind hole 242b and a groove 242c matched with the top surface of the antenna 400. The blind hole 242b is preset with a first spring 242b-1. Each pressing plate 242 corresponds to a set of spring groups 243.

[0063] Reference Figure 6 The spring assembly 243 is a component that can automatically reset after being squeezed. The spring assembly 243 includes a stopper 243a, a second spring 243b and a third spring 243c. The stopper 243a is provided with two third through holes 243a-1 and one fourth through hole 243a-2. The second spring 243b and the third spring 243c are respectively placed in the two third through holes 243a-1.

[0064] The assembly process of the clamping piece 240 is as follows: first, assemble the limit piece 243a into the first through groove 241a of the connecting plate 241, then place the pressing plate 242 under the connecting plate 241, and place the first spring 242b-1 into the first through hole 241b of the connecting plate 241, and finally place the second spring 243b and the third spring 243c into the two third through holes 243a-1 respectively, so that the other ends of the second spring 243b and the third spring 243c are respectively placed in the two second through holes 242a.

[0065] Preferably, the bottom of the antenna 400 has a protruding column 460 for routing the internal wiring of the antenna.

[0066] In this embodiment, the first driver 212 drives the connecting plate 241 to drive the pressure plate 242 to move along the first direction X until the groove 242c of the pressure plate 242 is engaged with the top surface of the antenna 400, and the raised column 460 of the antenna 400 abuts against the platform 111. The depressions of the platform 111 and the pressure plate 242 are used to limit the bottom and top surface of the antenna 400 respectively, so that the bottoms of one or more antennas 400 that need to be detected simultaneously are on the same horizontal plane.

[0067] In one embodiment provided in this application, refer to Figure 8 The second power member 220 includes a second driver 221 and a second slider 222 and a third slider 223 disposed in a guide groove 221a of the second driver 221. The second driver 221 is a standard power-driven member that can drive the second slider 222 and the third slider 223 to move relative to each other along the guide groove 221a.

[0068] Reference Figure 7 The clamping member 230 includes a first linkage member 231, a second linkage member 232, a first clamping plate 233 and a second clamping plate 234. The first linkage member 231 is connected to the second slider 222 and the first clamping plate 233 respectively, and the second linkage member 232 is connected to the third slider 223 and the second clamping plate 234 respectively. For example, when the number of the first clamping plate 233 and the second clamping plate 234 is one, when the second slider 222 and the third slider 223 are driven to move relative to each other by the second driver 221, the second slider 222 drives the first linkage member 231 to move, and the third slider 223 drives the second linkage member 232 to move. At the same time, the first linkage member 231 drives the first clamping plate 233 to move, and the second linkage member 232 drives the second clamping plate 234 to move, so that the first clamping plate 233 and the second clamping plate 234 clamp the antenna 400.

[0069] In this embodiment, the second driver 221 drives the second slider 222 and the third slider 223 to move relative to each other along the second direction Y, driving the correspondingly connected first linkage member 231 and the second linkage member 232 to respectively drive the first clamping plate 233 and the second clamping plate 234 to move, so as to clamp the antenna 400.

[0070] In one embodiment provided in this application, refer to Figure 7 The first linkage member 231 includes a first moving block 231a connected to the second slider 222 and a frame connecting member 231b, wherein the frame connecting member 231b is fixedly connected to the first moving block 231a and a plurality of first clamping plates 233. The frame connecting member 231b has a long strip through hole 231b-1, and the long strip through hole 231b-1 penetrates the frame connecting member 231b from front to back along the first direction X. When the second driver 221 drives the second slider 222 to move, the first moving block 231a moves accordingly, thereby driving the frame connecting member 231b connected to the first moving block 231a, and then driving the plurality of first clamping plates 233 connected to the frame connecting member 231b, so that when the second slider 222 moves, all the first clamping plates 233 move simultaneously.

[0071] Reference Figure 7 The second linkage member 232 includes a second moving block 232a connected to the third slider 223 and a strip connecting member 232b, wherein the strip connecting member 232b is respectively connected to the second moving block 232a and a plurality of second clamping plates 234. The strip connecting member 232b is placed in the long strip through hole 231b-1, so that when the second driver 221 drives the second slider 222 and the third slider 223 to move at the same time, the frame connecting member 231b and the strip connecting member 232b can avoid each other.

[0072] Since the strip connecting member 232b is placed in the long strip through hole 231b-1, in order to prevent the movements of the second slider 222 and the third slider 223 from interfering with each other, an avoidance groove 231a-1 is provided on the first moving block 231a connected to the second moving block 222. The strip connecting member 232b moves along the avoidance grooves 231a-1 on each second moving block 232a, and the avoidance grooves 231a-1 will not interfere with the movement of the strip connecting member 232b.

[0073] In this embodiment, the first moving block 231a, multiple first clamps 233, the frame connector 231b, the second moving block 232a, multiple second clamps 234 and the strip connector 232b can be used to simultaneously detect multiple groups of antennas 400, and the effect of simultaneously clamping multiple antennas 400 can be achieved through only one second driver 221.

[0074] In one embodiment provided in the present application, a third power component 130 is provided on the bracket 100, and the third power component 130 includes a third driver 131, a belt transmission component 132 and a guide rail 121. The third driver 131 is electrically connected to the control component, and the control component controls the start and stop of the third driver 131.

[0075] The third power member 130 refers to a power member used to drive the first power member 210 to move along the guide rail 121. The third driver 131 can be hydraulically driven, electrically driven, or electrically driven. In this embodiment, the third driver 131 is electrically driven as an example and is illustrated in the accompanying drawings. The belt transmission member 132 includes a driving wheel 132a, a driven wheel 132b, and a conveyor belt 132c. The conveyor belt 132c is sleeved on the outside of the driving wheel 132a and the driven wheel 132b. The driving wheel 132a is connected to the third driver 131. The driving wheel 132a is driven to rotate by the third driver 131, so that the conveyor belt 132c moves, and then drives the driven wheel 132b to rotate together. Among them, the coupling member 211 of the first power member 210 is connected to the conveyor belt 132c, and the connection method can be a snap connection, or it can be by placing fixing plates above and below the conveyor belt 132c, and connecting the two fixing plates with bolts and nuts to fix the relative position of the first power member 210 and the conveyor belt 132c.

[0076] At the same time, the engaging member 211 of the first power member 210 is also buckled on the guide rail 121 , and the third driver 131 drives the driving wheel 132 a to rotate, thereby driving the conveyor belt 132 c and the first power member 210 to move along the guide rail 121 .

[0077] In this embodiment, the control component is preferably a PLC controller, and the detection method is described below using the PLC controller.

[0078] First, the platform to be tested rotates the antenna 400 to be tested to a position close to the clamping assembly 200 where the antenna 400 can be clamped. The first driver 212 is controlled by the PLC controller to drive the first slider 213 to move downward until the position sensor corresponding to the first driver 212 sends a signal to the PLC controller, and the first driver 212 stops working. At this time, the pressure plate 242 is close to the inclined surface of the top of the antenna 400 to be tested under the action of the spring group 243. When the PLC controller receives the signal from the position sensor of the first driver 212, the PLC controller controls the second slider 222 and the third slider 223 of the second driver 221 to move relative to each other (if the second driver 221 is hydraulically driven, the cylinder is controlled to shrink) to drive the first clamping plate 233 and the second clamping plate 234 to move relative to each other so as to clamp the antenna 400. The position sensor of the second driver 221 sends a signal to the PLC controller. At this time, all antennas 400 to be tested are fixed in the same horizontal plane. When the PLC controller receives a signal from the position sensor corresponding to the second driver 221, the PLC controller controls the first driver 212 to drive the first slider 213 to move upward, and the position sensor corresponding to the first driver 212 sends a signal to the PLC controller. The PLC controller receives the signal from the position sensor of the first driver 212, and the PLC controller controls the third driver 131 to operate to drive the clamping assembly 200 to move to the detection area (between the first light source 310 and the second light source 320). After moving to the detection area, the third driver 131 sends a pulse completion signal (taking the third driver 131 as a servo motor as an example).

[0079] The PLC controller receives a pulse completion signal from the third driver 131, and the PLC controller controls the first driver 212 to drive the second power part 220 and the clamped antenna 400 to be inspected to move to the bottom of the antenna 400 and the coplanar with the central axis of the camera 330, and then the position sensor corresponding to the first driver 212 sends a signal. After the PLC controller receives the signal from the position sensor corresponding to the first driver 212, it controls the triggering camera 330 to transmit the image acquisition signal to the host computer through the industrial Ethernet TCP protocol. The host computer algorithm software triggers the industrial camera by calling the SDK soft trigger of the camera 330. The camera 330 starts to collect image signals and transmits them to the host computer through the USB data cable, and then performs visual inspection. After the inspection is completed, a product qualified or unqualified signal is issued.

[0080] After the algorithm software determines the qualified and unqualified signals of the product, it transmits them to the PLC controller of the snap-on antenna 400 assembly equipment through the industrial Ethernet TCP protocol, and then starts the next action.

[0081] If the PLC controller receives a product qualified signal, the PLC controller controls the third driver 131 to move, drives the clamping assembly 200 to move to the qualified product unloading position, and the third driver 131 sends a pulse completion signal. If the PLC controller receives a product unqualified signal, the PLC controller controls the third driver 131 to move, drives the clamping assembly 200 to move to the unqualified product unloading position, and the third driver 131 sends a pulse completion signal.

[0082] The PLC controller receives the pulse completion signal from the third driver 131, controls the second driver 221 to drive the second slider 222 and the third slider 223 to move in opposite directions (if the second driver 221 is hydraulically driven, the cylinder is controlled to extend) to drive the first clamping plate 233 and the second clamping plate 234 to move in opposite directions to release the antenna 400, and the position sensor corresponding to the second driver 221 sends a signal. At this time, the product falls into the qualified product box or the unqualified product box, and the unloading is completed. When the PLC controller receives the signal from the position sensor corresponding to the second driver 221, it controls the first driver 212 to drive the first slider 213 to move upward, and the position sensor corresponding to the first driver 212 sends a signal. When the PLC controller receives the signal from the position sensor corresponding to the first driver 212, it controls the third driver 131 to drive the first power member 210 to move the clamping assembly 200 to the initial position, and the third driver 131 sends a pulse completion signal. At this time, a detection cycle is completed.

[0083] In one embodiment provided in the present application, the detection assembly 300 further includes an adjustment member 360 , and the first light source 310 is connected to the first connecting rod 340 via the adjustment member 360 . The first light source 310 can move and flip relative to the first connecting rod 340 .

[0084] In this embodiment, the angle and height of the first light source 310 relative to the antenna 400 to be detected can be adjusted by the adjusting member 360 and can be flexibly adjusted according to needs so that the first light source 310 can highlight the features of the buckle surface of the antenna 400 to be detected.

[0085] In one embodiment provided in the present application, the detection assembly 300 further includes a background plate 370 disposed on the first connecting rod 340 , and the background plate 370 and the first light source 310 are both placed facing the direction of the second light source 320 .

[0086] In this embodiment, the background plate 370 can reduce the influence of ambient light on the detection result.
