[0032] Embodiment:
[0033] Figure 1 is the first view of a pick-and-place positioning device for FPC provided by an embodiment of the present utility model, Figure 2 is the second view of a pick-and-place positioning device for FPC provided by an embodiment of the present utility model. As shown in combination with Figure 1 and Figure 2 the pick-and-place positioning device includes a loading station 1, a positioning station 2, a waste box 3 and a transfer assembly 4.
[0034] The loading station 1 is used for loading FPC, the positioning station 2 is used for supporting FPC, one side of the positioning station 2 is provided with a camera 21, and the camera 21 is used for taking pictures of the FPC on the positioning station 2. The waste box 3 is used for collecting abnormal FPC.
[0035] The transfer assembly 4 includes a picking head 41 and a rotating motor 42. The picking head 41 is used for picking and placing FPC. The output shaft of the rotating motor 42 is in transmission connection with the picking head 41 to drive the picking head 41 to transfer to the loading station 1, the positioning station 2 and the waste box 3. The camera 21 is electrically connected to the rotating motor 42 and the picking head 41 respectively.
[0036] For a device for picking up and placing FPC provided in an embodiment of the utility model, when transporting and positioning the FPC, first, the FPC is grabbed from the loading station 1 by the material picking head 41. Then, the material picking head 41 is driven to rotate by the rotary motor 42, so that the material picking head 41 rotates to the positioning station 2, and the material picking head 41 places the FPC on the positioning station 2. Next, the camera 21 takes a picture of the FPC on the positioning station 2, and transmits the generated position information of the FPC accordingly, thereby finally realizing the precise positioning of the FPC. The manipulator can accurately grab the FPC according to the received position information and realize its connection with the display module. When the camera 21 takes a picture and analyzes and determines that the FPC is abnormal, the camera 21 transmits the abnormal information to the material picking head 41 and the rotating motor 42, and the material picking head 41 grabs the FPC again on the positioning station 2, and drives the material picking head 41 to the waste box 3 through the rotating motor 42. The material picking head 41 places the abnormal FPC in the waste box 3 for collection, thereby automatically completing the collection of abnormal products through the waste box 3, avoiding the problem of manually eliminating abnormal FPCs after the entire equipment is shut down, and improving the detection efficiency. After that, the rotating motor 42 drives the material picking head 41 to the loading station 1 again to transfer and position the next FPC.
[0037] That is to say, the embodiment of the utility model provides a positioning device for picking up and placing FPC, which automatically completes the collection of abnormal products through the waste box 3, avoids the problem of manually eliminating abnormal FPC after the entire equipment is shut down, and improves the detection efficiency.
[0038] Exemplarily, the positioning station 2 may be a stage or other supporting structure.
[0039] In this embodiment, the loading station 1 can be a material bin, and the material bin has a positioning groove for positioning the FPC. The positioning groove of the material bin can realize the positioning of the FPC, ensuring that the material taking head 41 can reliably take the material.
[0040] Exemplarily, the silo includes a bottom plate and a plurality of side plates, each of which is vertically fixed on the bottom plate to form a positioning groove.
[0041] Furthermore, the positioning groove is used to stack multiple FPCs in sequence, and the transfer assembly 4 also includes a linear module 43, which is located on the output shaft of the rotating motor 42, and the linear module 43 is connected to the material taking head 41 in a transmission manner to drive the material taking head 41 to rise and fall in the vertical direction relative to the positioning groove. In other words, multiple FPCs can be stored in the silo at the same time, and with the cooperation of the linear module 43, the material taking head 41 can take the sheets from top to bottom in sequence.
[0042] It should be noted that in other embodiments of the present invention, the loading station 1 may also be a conveyor line, that is, the loading of the FPC is achieved through the conveyor line, and the present invention does not impose any limitation on this.
[0043] Continue to see Figure 1 The transfer component 4 also includes a light source 44, which is located on the output shaft of the rotating motor 42, and the light source 44 and the material taking head 41 are staggered in the horizontal direction.
[0044] In the above embodiment, the rotating motor 42 can drive the light source 44 to the positioning station 2 (at this time the material picking head 41 is not at the positioning station 2), providing lighting conditions for the camera 21 to take pictures, and avoiding the problem that the material picking head 41 will interfere with the light source 44 and cause lighting shadows when the light source 44 is arranged on the material picking head 41, thereby avoiding affecting the camera 21 taking pictures.
[0045] Exemplarily, the light source 44 can be a finished light source, which increases the light-emitting area, avoids the occurrence of abnormal alignment alarms, and at the same time increases the life of the light source and reduces losses.
[0046] Exemplarily, the light source 44 is located above the camera 21 .
[0047] In an implementation of the present invention, a bracket 45 is disposed on the output shaft of the rotating motor 42 , and two ends of the bracket 45 are respectively connected to the output shaft of the rotating motor 42 and the light source 44 .
[0048] It is easy to understand that the irradiation area of the light source 44 can be increased with the support of the bracket 45.
[0049] In this embodiment, a proximity sensor 22 is installed on the positioning station 2. The sensing end of the proximity sensor 22 is used to detect the FPC to determine whether the FPC is placed on the positioning station 2 (see Figure 3 ).
[0050] In the above embodiment, the proximity sensor 22 can determine whether the FPC is properly placed on the positioning station 2, thereby serving as a basis for the camera 21 to start taking pictures.
[0051] In addition, the pick-and-place positioning device further includes a lateral movement module 5, the output end of which is transmission-connected to the camera 21 to drive the camera 21 to move horizontally. The lateral movement module 5 adjusts the position of the camera 21 in the horizontal direction to facilitate the maintenance of the camera 21. In addition, driven by the lateral movement module 5, the camera 21 can simultaneously take pictures of adjacent pick-and-place positioning devices, that is, two pick-and-place positioning devices can be shared by one camera 21.
[0052] Similarly, the waste box 3 can also share two pick-and-place positioning devices.
[0053] Preferably, the angle between the loading station 1 and the waste box 3 and the output shaft of the rotating motor 42 is 90°, that is, when the feeding head 41 switches between the loading station 1 and the waste box 3, the rotating motor 42 rotates exactly 90°; the angle between the waste box 3 and the positioning station 2 and the output shaft of the rotating motor 42 is 90°, that is, when the feeding head 41 switches between the positioning station 2 and the waste box 3, the rotating motor 42 rotates exactly 90°, thereby avoiding mutual influence between the three stations.
[0054] In this embodiment, the material picking head 41 includes a mounting plate and a plurality of suction cups, the mounting plate is drivingly connected to the output shaft of the rotating motor 42, and the plurality of suction cups are arranged at intervals on the bottom surface of the mounting plate, so that the picking and unloading of the FPC can be achieved through the plurality of suction cups.
[0055] It should be noted that in other embodiments of the present invention, the material taking head 41 may also be a manipulator or an electric gripper, and the present invention does not limit this.
[0056] The embodiment of the utility model further provides a testing device, which includes a pick-up and placement positioning device for FPC as described above.
[0057] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
