Description

Technical Field

[0002] A filter is a frequency-selective device that allows specific frequency components in a signal to pass through while greatly attenuating other frequency components. The frequency-selective function of the filter can be used to filter out interference noise or perform spectrum analysis.

[0038] Wherein, the transmission component 2, the test component 3 and the grabbing manipulator 4 are electrically connected to the main controller 5 respectively;

[0039] The image acquisition component 1 is set at the front end of the transmission component 2 to capture the image on the transmission component 2; the main controller 5 positions the filter 5 on the transmission component 2 according to the image, and controls the grasping robot 4 to grasp the filter 5 according to the positioning result and places the filter 5 on the test component 3 for testing.

[0040] The working principle and beneficial effects of the above technical solution are:

[0041] The filter testing device of the present invention transports the finished filter 5 to the grabbing area corresponding to each grabbing manipulator 4 through the transmission component 2; in order to achieve accurate grabbing, it is necessary to position each filter 5 on the transmission component 2, and the positioning mainly involves analyzing the image captured by the image acquisition component 1, thereby marking and determining the position of the filter 5 on the image acquisition area of ​​the image acquisition component 1, and then combining the transmission speed of the transmission component 2 to achieve accurate positioning of the position of each filter 5 on the transmission component 2; after achieving accurate positioning, the grabbing manipulator 4 can be controlled to grab; the grabbing manipulator 4 grabs the filter 5 and places the filter 5 on the test component 3 for testing, and after the test is completed, the grabbing manipulator 4 can be controlled to take the filter 5 out of the test component 3, and the qualified filter is placed in the qualified test area, and the unqualified filter is placed in the unqualified test area; the qualified test area and the unqualified test area can be configured between the test component 3 and the transmission component 2. Among them, the image acquisition component 1 includes a camera 48 set on the gantry; the transmission component 2 includes a conveyor belt.

[0042] In one embodiment, Figure 3 and Figure 4 As shown, the grasping robot 4 includes: two first guide rails 41 arranged in parallel and located above the transmission component 2, second guide rails 43 with two ends respectively arranged on the two first guide rails 41, a moving platform 42 arranged on the second guide rails 43, a first telescopic mechanism 44 arranged below the moving platform 42, a rotating ring 45 arranged at the end of the first telescopic mechanism 44, and a camera 48 arranged on the lower end surface of the rotating ring 45, an L-shaped member 46 arranged on the outer periphery of the rotating ring 45, and a suction cup 47 arranged at the end of the L-shaped member 46.

[0043] Among them, Figure 5 As shown, the test component 3 includes: a test platform 34 for placing the filter 5 and a cover plate 32 arranged at the end of the lifting device 31; a groove 35 for accommodating the filter 5 is arranged on the test platform 34; a test probe assembly 33 is arranged on the cover plate 32 at a position corresponding to the groove 35; a plurality of through holes and a plurality of guide pillars are respectively arranged on the cover plate 32 and the test platform 34, and the guide pillars and the through holes realize the positioning between the test probe assembly 33 on the cover plate 32 and the pin piece 6 of the filter 5 in the groove 35.

[0044] The working principle and beneficial effects of the above technical solution are:

[0045] The movement of the gripping manipulator 4 above the transmission component 2 in this embodiment is mainly realized by the first guide rail 41, the second guide rail 43 and the mobile platform 42; the mobile platform 42 can slide on the second guide rail 43, and the second guide rail 43 can slide on the first guide rail 41; the specific implementation method is: the first guide rail 41 and the second guide rail 43 can be configured as a ball screw guide rail or an electric cylinder guide rail or a pneumatic cylinder guide rail. After moving to the position, the first telescopic mechanism 44 is controlled to extend and then the suction cup 47 is moved to the top of the filter 5 and contacts the filter 5. The suction cup 47 sucks the filter 5. The suction of the filter 5 is realized by the above action. The L-shaped component 46 is set to realize the suction cup 47 extending into the test component 3, so as to facilitate the placement of the filter 5 in the test component 3 for testing and to suck the filter 5 out of the test component 3 again; the camera 48 is set to reposition the filter 5 during the suction process, so as to facilitate the adjustment of the suction position.

[0046] When the grabbing manipulator 4 places the filter 5 in the groove 35 on the test platform 34, the cover plate 32 is engaged with the test platform 34 under the action of the lifting device 31, and the probe on the test probe assembly 33 on the cover plate 32 contacts the pin piece 6 of the filter 5 in the groove 35, so that it is convenient for the signal generating unit of the test component 3 to input the signal into the filter 5 and receive the output of the filter 5 through the signal receiving unit, and judge the filter 5 according to the output and the pre-configured output threshold. In addition, a display screen can also be configured to display the test process and test results of the filter 5.

[0047] In order to further improve the test efficiency, in one embodiment, the filter test device further includes: a qualified product packaging component, which is used to package the qualified products detected by the test component 3;

[0048] Among them, Figure 6 As shown, the qualified product packaging component includes: a first unloading unit 61, a second unloading unit 62, a pressing unit 63 and a receiving unit 64; the first unloading unit 61 is arranged on one side of the test component 3; the second unloading unit 62, the pressing unit 63 and the receiving unit 64 are arranged on the other side of the test component 3; the first unloading unit 61 releases a first tape 65 provided for accommodating a cavity of the filter 5; the first tape 65 passes under the test platform of the test component 3 and is sent into the pressing unit 63, and synchronously the second unloading unit 62 sends the second tape used for sealing the cavity into the pressing unit 63; the pressing unit 63 presses the first tape 65 and the second tape to form a third tape for packaging the filter 5; the receiving unit 64 winds up and receives the third tape.

[0049] Among them, a gate valve 38 is arranged at the bottom of the groove 35 of the test platform 34, and a blanking chute 36 is arranged on the gate valve 38; the end surface shape of the upper end of the blanking chute 36 is adapted to the shape of the filter 5, and the end surface shape of the lower end is adapted to the cavity of the first strip 65; and a blanking sensing probe 37 is arranged on the side wall near the end surface of the lower part of the blanking chute 36. The blanking sensing probe 37 includes: a proximity sensor; by testing the blanking of the filter 5 to realize the control of the actions of the first unloading unit 61, the second unloading unit 62, and the receiving unit 64, the continuous packaging of the filter 5 is realized.

[0050] The first discharge unit 61 is arranged in the first main body 50; the second discharge unit 62, the pressing unit 63 and the receiving unit 64 are arranged in the second main body 60; a discharge port is arranged on a side of the first main body 50 close to the test component 3, and a first clamping mechanism 66 is arranged on the discharge port; a feed port is arranged on a side of the second main body 60 close to the test component 3, and a second clamping mechanism 67 is arranged on the feed port;

[0051] Among them, Figure 7 As shown, the first clamping mechanism 66 or the second clamping mechanism 67 comprises: two symmetrically arranged C-shaped clamping bodies 661, a first clamping roller 662 and two symmetrically arranged second clamping rollers 663; positioning rods 664 are arranged at both ends of the first clamping roller 662 and on the side of the second clamping roller 663 close to the C-shaped clamping body 661; the positioning rod 664 penetrates into the connecting groove arranged on the C-shaped clamping body 661; the first clamping roller 662 and the second clamping roller 663 are arranged at the opening position of the C-shaped clamping body 661; and the second telescopic mechanism 665 is arranged between the first clamping roller 662 and the second clamping roller 663 and both ends of the C-shaped clamping body 661;

[0052] The length of the second clamping roller 663 is less than 1 / 2 of the length of the first clamping roller 662 ; the spacing between the two second clamping rollers 663 is greater than or equal to the width of the portion of the cavity tested from the lower end surface of the first strip 65 and is less than the width of the first strip 65 .

[0053] The first body 50 is arranged on the translation guide rail 501 .

[0054] The second unloading unit 62 includes: an unloading roller shaft 621 and at least one positioning roller 622 ; the positioning roller 622 is arranged above the first strip 65 being fed next to a side of the lamination unit 63 close to the test assembly 3 .

[0055] The working principle and beneficial effects of the above technical solution are:

[0056] In this embodiment, a gate valve 38 and a blanking chute 36 are arranged under the groove 35 of the test platform 34, so that the filter 5 can slide down from the blanking chute 36 after the test is completed, and there is no need to use the grasping manipulator 4 to take the material after the test is completed, thereby improving the test efficiency of the test device; in addition, the packaging of qualified products can be achieved through the qualified product packaging component, but the following steps can be adopted for unqualified products: a receiving tray is placed under the blanking chute 36; when unqualified, the first main body 50 slides a certain displacement on the translation guide rail 501, and after the displacement, the first strip 65 is moved away from the corresponding position of the blanking chute 36, so that the unqualified filter 5 falls into the receiving tray; in order to ensure that the displacement of the first main body 50 does not cause damage to the first strip 65, the first clamping mechanism 66 relaxes the clamping force, the second clamping mechanism 67 increases the clamping force, and the first clamping mechanism 68 increases the clamping force. A material discharge unit 61 adaptively performs material discharge control, and can adaptively rewind in the process of moving back to the original position, and keeps the second clamping mechanism 67 clamping the first strip 65 during rewinding; the clamping force of the first clamping mechanism 66 and the second clamping mechanism 67 is adjusted by the telescopic second mechanism 665 provided between the first clamping roller 662 and the second clamping roller 663 and the two ends of the C-shaped clamping body 661; wherein the second telescopic mechanism 665 includes any one of a telescopic electric cylinder, a telescopic air cylinder, and a spring; in order to ensure the clamping effect, the end face of the second clamping roller 663 should correspond to any position between the edge of the first strip 65 and the middle of the area of ​​the outer arm of the cavity to the outer wall of the cavity; the pressing unit 63 realizes the pressing between the first strip 65 and the second strip, which is an existing mature structure and will not be explained in detail here; the receiving unit 64 includes a receiving roller. In order to achieve the auxiliary fixation of the position of the second clamping roller 663, the end of the second telescopic mechanism 665 is arranged in the annular groove of the second clamping rod 663 and the contact surface of the end with the second clamping roller 663 is set as an arc surface. Similarly, the first clamping rod 662 and the second telescopic mechanism 665 can also be connected in the same way. This part of the structure is not shown in FIG. Figure 7 Shown in.

[0057] Due to the uncertainty of the filter 5 during the transmission process, the orientation of the filter 5 may not correspond to the orientation required by the test component 3. In order to implement the test of this part of the filter 5, in one embodiment, the filter test device further includes: a filter switching component;

[0058] like Figure 8 As shown, the filter switching assembly includes: a symmetrically arranged elastic clamping body 71 (rubber pad or resilient foam pad), a third telescopic mechanism 72 and a rotating mechanism 73; one end of the third telescopic mechanism 75 is fixedly connected to the elastic clamping body 71, and the other end is connected to the rotating mechanism 73; the rotating mechanism 73 is fixed to the side of the test assembly 3 close to the transmission assembly 2 through an L-shaped fixing body 74.

[0059] After the grabbing manipulator 4 grabs the filter 5 and before placing it into the test assembly 3, the filter 5 is placed between the two elastic clamping bodies 71, the third telescopic mechanism 72 is extended, the filter 5 is clamped between the two elastic clamping bodies 71, and then the rotating mechanism 73 is rotated to adjust the position of the filter 5; the grabbing manipulator 4 grabs the filter 5 and places it on the test assembly 3. In addition, the position of the filter 5 can also be flipped during the secondary screening of unqualified products after the test assembly 3 is tested. Specifically, the unqualified products slide through the blanking chute 36 to the receiving tray set below the blanking chute 36. If secondary screening is required, the filter 5 in the receiving tray can be directly poured onto the front end of the transmission assembly 2 for flattening, and then secondary screening is performed.

[0060] In order to reasonably utilize the space on both sides of the transmission component 2, in one embodiment, the test components 3 are alternately arranged on both sides of the transmission component 2. In addition, the distance that the transmission component 2 needs to transmit can be reduced, saving energy.

[0061] The present invention also provides a filter testing method, comprising:

[0062] Capturing an image on the transmission component by an image acquisition component disposed at the front end of the transmission component;

[0063] Positioning a filter on a transmission component based on the image;

[0064] The grasping robot is controlled to grasp the filter according to the positioning result and place the filter on the test assembly for testing.

[0065] The positioning step includes:

[0066] Step S1: Identify the image, identify each filter in the image and determine the position of the filter corresponding to the image;

[0067] Specifically, the image is firstly contour extracted, and the extracted contour is matched with the standard contour corresponding to the pre-configured filter. When the match is satisfied, the coordinates of the area center of the contour of the filter on the coordinate axis corresponding to the image are determined;

[0068] Step S2: constructing the transmission positioning coordinate axis;

[0069] like Fig. 9 As shown, the transmission positioning axis includes: an X-axis parallel to the transmission direction, a Y-axis along the width direction of the transmission component, and a transmission area corresponding to the transmission surface of the transmission component; the coordinates in the transmission area are updated in the positive direction of the X-axis in turn according to the transmission direction and the transmission speed;

[0070] Step S3: Mapping the filters to the positioning coordinate axis according to the positions of the filters in the image and the regions on the positioning coordinate axis corresponding to the image.

[0071] The mapping process is actually a coordinate system conversion process. After the corresponding relationship between each point on the image and each point on the positioning coordinate axis is known, the coordinate conversion can be performed directly. In addition, the area corresponding to the transmission component in the positioning coordinate axis is dynamically updated. According to the transmission direction and transmission speed, the coordinates of the filter on the positioning coordinate axis are updated. The specific coordinates are (x+vt,y); where v is the transmission speed and t is the transmission time.

[0072] Among them, the control steps of the grabbing manipulator are as follows:

[0073] Step A1: When placing the filter on the test platform, the gripper determines the target filter from the positioning coordinate axis;

[0074] The grasping area and the target determination area of ​​the grasping manipulator are divided in the positioning coordinate axis; the grasping area is the set of all points that the grasping manipulator can grasp from the transmission component; the target determination area is the area where the grasping area is translated a certain distance in the opposite direction of the transmission direction; the distance is less than or equal to 1 / 2 of the width of the grasping area along the transmission direction; the target filter is the rightmost side filter in the target determination area;

[0075] Step A2: Determine the grabbing points to be screened according to the target filter;

[0076] The grasping point to be screened is parallel to the point where the center of the target filter is located and the grasping manipulator located in front of the transmission direction corresponds to the point in the grasping area on the transmission component, that is, the point in the grasping area where the center point of the target filter passes after the transmission of the transmission component;

[0077] Step A3: Determine the shortest time for the grabbing manipulator to move to the corresponding state of placing the filter on the test platform to grab the components on each grabbing point to be screened as the first time, and the time for the target filter to move to the grabbing point to be screened driven by the transmission component as the second time;

[0078] The grasping manipulator moves to the corresponding state when placing the filter on the test platform to the shortest time for grasping the components on each grasping point to be screened, which can be determined by querying the constructed shortest time determination table; the grasping point and the shortest time in the shortest time determination table are correspondingly associated, and in addition, the maximum fluctuation value can also be correspondingly associated; the maximum fluctuation value is the maximum difference of the shortest time for grasping the same point multiple times;

[0079] Step A4: Eliminate the grasping points to be screened whose first time is greater than the second time; use any one of the remaining grasping points to be screened as a grasping point; and control the grasping manipulator.

[0080] Specifically, the grasping robot can be controlled to move to the top of the grasping point first, and then when the filter moves to the grasping point, the suction cup is controlled to adsorb downward, so that the transmission component can be grasped without pausing, avoiding frequent pausing of the transmission component and improving efficiency.

[0081] In addition, in order to ensure both successful grasping and grasping efficiency, the maximum fluctuation value of the shortest time for the grasping robot to move to the corresponding state when the filter is placed on the test platform can be comprehensively analyzed to grasp the components on each grasping point to be screened; the maximum fluctuation value is then used to further screen and eliminate the grasping points to be screened, and then the grasping point to be screened with the shortest time in the first time is used as the grasping point.

[0082] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
