DETAILED DESCRIPTION

[0025] like Figures 1 to 5 As shown, a press-fitting system for controlling the buckle of a board includes a feeding mechanism and a pressing mechanism.

[0026] like Figure 3 As shown, the feeding mechanism includes a workbench 1, a fixture 2, and a first driving device 3. The workbench 1 is provided with a feeding station 4 and a pressing station 5. The workbench 1 is provided with a machine cover 33, which covers the pressing station 5, and a controller is installed on the back of the machine cover 33. The first driving device 3 is installed on the workbench 1. The first driving device 3 can be a rodless cylinder or a linear module. The first driving device 3 is drivingly connected to the fixture 2. The first driving device 3 can drive the fixture 2 to reciprocate between the feeding station 4 and the pressing station 5, reducing manual walking and facilitating rapid loading and unloading.

[0027] The fixture 2 carries the control board 6 and the fastener 7, please refer to Figure 2 The control board 6 has a special-shaped structure with concave and convex curved surfaces. A card slot 8 for fitting a fastener 7 is provided on the surface of the control board 6. The fastener 7 is an ITO LENS lens, which is pressed into the card slot 8 by a pressing mechanism.

[0028] Please refer to Figures 3 to 5 The pressing mechanism includes a stand 9, a second driving device 10 and a die 11. The stand 9 is fixedly mounted on the workbench 1. The second driving device 10 is mounted on the stand 9 and is located directly above the pressing station 5. The second driving device 10 can be a cylinder. The die 11 is mounted on the output end of the second driving device 10. The bottom of the die 11 has a pressing surface 12 that is at least partially shaped like the control board 6. A pressing block 13 for extruding the fastener is provided at the bottom of the die 11 corresponding to the position directly above the card slot 8. The second driving device 10 drives the die 11 downward so that the pressing block 13 presses the fastener 7 into the card slot 8.

[0029] The fixture 2 includes a slide plate 14 and a fixture base plate 15. The first drive device 3 is drivingly connected to the slide plate 14. The first drive device 3 is a rodless cylinder or a linear module. The controller is connected to the first drive device 3. Two linear guide rails 16 extending from the loading station 4 to the pressing station 5 are installed on the workbench 1. A slider that slides along the linear guide rails 16 is installed at the bottom of the slide plate 14. The slide plate 14 supports the fixture base plate 15 and the slide plate 14 and the fixture base plate 15 are positioned by at least two positioning pins 17. The two positioning pins 17 are diagonally distributed to enhance the positioning effect. An enclosure 18 for positioning the control board is provided on the fixture base plate 15. The enclosure 18 fits the edge of the control board 6. When loading, the control board 6 is placed between the two oppositely arranged enclosures 18. Opposing photoelectric sensors 19 are installed on the left and right sides of the enclosure 18, respectively, and the opposing photoelectric sensors 19 are connected to the controller. When the control board 6 is placed stably on the fixture bottom plate 15, the virtual horizontal light 32 emitted by the transmitting end of the through-beam photoelectric sensor 19 is just pressed above the left and right sides of the control board 6, so that the receiving end of the sensor can receive the light; otherwise, the control board 6 will block the virtual horizontal light 32 from propagating to the receiving end. Therefore, the through-beam photoelectric sensor 19 can be used to detect whether the control board 6 is loaded in place, thereby improving the reliability of the press-fitting quality. When the through-beam photoelectric sensor 19 detects that the control board 6 is loaded in place, the controller controls the second drive device 10 to start the press-fitting action. A positioning blind hole 20 is provided at the top of the enclosure 18, and a positioning column 21 that cooperates with the positioning blind hole 20 is provided at the bottom of the die 11. The positioning column 21 is inserted into the positioning blind hole 20 when the die is closed.

[0030] The jig bottom plate 15 is provided with a supporting convex surface 22 that fits the bottom surface of the control board 6. The distribution position of at least part of the supporting convex surface 22 corresponds to the pressing surface 12. The supporting convex surface 22 cooperates with the pressing surface 12 to clamp the control board 6 to prevent the control board 6 from being deformed or shaken during the press-fitting process. The jig bottom plate 15 is also provided with a top block 23 that supports the card slot 8. Similarly, the top block 23 cooperates with the pressing block 13 to clamp the control board 6 to prevent the card slot 8 from being deformed during the press-fitting process and affecting the assembly of the fastener 7.

[0031] The control panel 6 has a front panel surface 24 that is tilted downward. The bottom surface of the die 11 is provided with a pressing edge 25 that matches the edge of the control panel. The pressing edge 25 is convex downward to press the edge of the front panel surface 24. The inner side of the pressing edge 25 on the die is a plane structure that does not contact the main part of the front panel surface, which is convenient for processing the bottom surface of the die. The die 11 uses the pressing edge 25 to press the front panel surface 24, and cooperates with the supporting convex surface 22 and the pressing surface 12 to form a press-fitting method of concave and convex molds, so as to reliably press the control panel 6, prevent the irregular structure of the control panel from shaking during the press-fitting process, and improve the assembly accuracy and assembly efficiency.

[0032] A proximity switch 26 is installed on the workbench 1 to detect whether the die 11 is separated from the control board 6. The proximity switch 26 is connected to the controller and is installed at a height higher than the control board. When the die 11 moves upward to within the detection range of the proximity switch 26, the controller controls the first drive device 3 to drive the jig 2 to move toward the feeding station 4 to ensure the continuity of the assembly operation.

[0033] Please refer to Figure 1 The system also includes a feeding mechanism, which includes a feeding rack 27. The feeding rack 27 is provided with a waiting platform 28, a feeding platform 29 and an empty platform 30 for supporting the material frame. The waiting platform 28 is located above the empty platform 30. The waiting platform 28 is inclined toward the side of the upper feeding platform 29, and the empty platform 30 is inclined away from the feeding platform. Under normal conditions, the material frame in the feeding platform 29 is inclined toward the standing direction of the operator, which is convenient for taking materials. The bottom of the feeding platform 29 is hinged to the piston rod of the hydraulic cylinder 31, and the cylinder body of the hydraulic cylinder 31 is hinged to the feeding rack 27. The hydraulic cylinder 31 is used to drive the feeding platform 29 to alternately tilt and connect the waiting platform 28 and the empty platform 30, so that the full material frame slides onto the feeding platform 29, or the empty material frame slides onto the empty platform 30, so as to achieve smooth turnover of the material frame. Multiple feeding mechanisms of this system can be set to feed the control panel and the fasteners respectively. The system also includes a feeding mechanism, and the finished products after pressing are taken out into a tray of the feeding mechanism.

[0034] The working process of this system is as follows: the first drive device 3 translates the jig 2 to the loading station 4, the operator takes the control board 6 from the material frame and places it between the enclosure 18 of the jig 2, supported and positioned by the supporting convex surface 22 and the top block 23; then the fastener 7 is taken from another material frame and placed on the card slot 8 of the control board; the first drive device 3 moves the jig 2 to the pressing station 5, and after the through-type photoelectric sensor 19 detects that the control board 6 is in place, the controller controls the second drive device 10 to press down the die 11, and the pressing edge 25 on the front side of the bottom of the die 11 and the pressing surface 12 on the rear side simultaneously press the control board 6 (i.e., mold closing) to prevent the control board from warping or shaking, and at the same time, the raised pressing block 13 squeezes the fastener 7 into the card slot 8 to complete the assembly of the workpiece. The controller controls the second drive device 10 to move upward to the detection range of the proximity switch 26. The proximity switch 26 sends a detection signal to the controller. After receiving the signal, the controller controls the first drive device 3 to move the fixture 2 to the loading station 4, manually removes the finished product, and starts the cycle of assembling the next workpiece.
