The limit switch 424 is used for detection. Figure 3 In this embodiment of the application, the detection head of the limit switch 424 is a roller used to roll and contact the workpiece, and sends the detection result of presence or absence to the alarm device. When no workpiece is detected, the alarm device sounds an alarm and stops the operation of the device. After assembly, the connection position of the locking block 422 and the detection base plate 421 is adjusted to adjust the height of the limit switch 424. In addition, the height of the limit switch 424 can also be adjusted by adjusting the position of the limit switch 424 and the limit switch support 423.

After positioning, a fastener passes through the elongated through hole of the detection base plate 421 and screws into the card block threaded hole 4222 to fasten the detection base plate 421 and the card block 422. Figure 10 In the middle, two through holes 4223 are also provided on the card block 422, and fasteners are screwed through the through holes 4223 to the detection frame 44.

[0036] Furthermore, the function of the suction cup assembly described in this application is to pick up the workpiece, lift it upwards, and then have it removed by other devices for the next processing step, such as... Figure 2 and Figure 11 As shown, the suction cup assembly includes at least one vacuum suction cup 45, at least one fitting 414, at least one fitting base plate 46, a finger strip 413, a cylinder 47, and a cylinder adjustment bracket 49. The cylinder adjustment bracket 49 includes an angle iron portion 491 fixedly connected to the lifting frame 48 and a cylinder connecting portion 492 fixedly connected to the cylinder 47; both connections are made using fasteners. The piston rod of the cylinder 47 is connected to the finger strip 413, and the finger strip 413 is fixedly connected to the at least one fitting base plate. Plate 46, the at least one fitting base plate 46 is fixedly connected to the at least one fitting 414, the at least one fitting 414 is fixedly connected to the at least one vacuum suction cup 45, the vacuum suction cup 45 is used to pick up the workpiece. In this embodiment, the number of vacuum suction cups 45, fittings 414 and fitting base plates 46 are the same, one fitting base plate 46 is connected to one fitting 414, and one fitting 414 is connected to one vacuum suction cup 45; during operation, the piston rod of the cylinder 47 moves... Figure 11 The up-and-down movement of the device simultaneously activates the finger bar 413, the hardware base plate 46, the hardware 414, and the vacuum suction cup 45. When the vacuum suction cup 45 contacts the workpiece downwards, it picks up the workpiece. When the vacuum suction cup 45 reaches its upward position, other devices remove the workpiece and move it to the next processing station. In this embodiment, the number of suction cup combinations is two, and the number of vacuum suction cups 45 is eight. However, this cannot be used to limit this application. The number of suction cup combinations and vacuum suction cups 45 is determined according to the number of workpieces picked up simultaneously.

[0037] Please refer to Figure 4 , Figure 5 and Figure 6The loading and detection device further includes a guide rail base assembly 2 and an upper slide assembly 3 for support. The guide rail base assembly 2 is used to move the upper slide assembly 3. Since the workpiece is mounted on the upper slide assembly 3, moving the upper slide assembly 3 can move the workpiece to the loading position. Figure 4 In the above, the guide rail base assembly 2 includes a Y-axis base plate 21, a lead screw 25 for moving the upper slide assembly 3, a motor 24 for driving the lead screw 25, a lead screw fixing seat 22 mounted on the Y-axis base plate 21 for fixing the lead screw 25, a Y-axis motor mounting plate 23 mounted on the Y-axis base plate 21 for fixing the motor 24, a lead screw nut 26 for connecting and actuating the upper slide assembly 3, a lead screw support seat 27 mounted on the Y-axis base plate 21 for supporting the lead screw 25, two slide rails 28 parallel to each other mounted on the Y-axis base plate 21 for sliding, a perforated coupling 29 for connecting the motor 24 and the lead screw 25, and a proximity switch 210 for sensing the upper slide assembly 3. The upper slide assembly 3 is equipped with two limit switches 212 for limiting the movement of the upper slide assembly 3; the inner edge of the lead screw nut 26 is threaded, and the outer edge is circular, with a connecting flange 261 on one side of the outer edge for fixing the connecting parts; during operation, the output shaft of the motor 24 is connected to the plum blossom coupling 29, which in turn drives the lead screw 25 to rotate. When the lead screw 25 rotates, it can drive the lead screw nut 26 to move, and it is a precise distance movement. The upper slide assembly 3 is fixedly connected to the lead screw nut 26. Therefore, when the lead screw 25 rotates and drives the lead screw nut 26 to move, the upper slide assembly 3 is also moved, with the aim of precisely moving the workpiece set on the upper slide assembly 3.

[0038] Please refer to Figure 5 and Figure 6 At work, Figure 6 The upper sliding platform assembly 3 described above is the orientation during operation. This orientation is used for ease of structural explanation. Figure 5 Place Figure 6The upper slide assembly 3 includes a main base plate 31 for support, at least two parallel sliders 32 for connecting the two slide rails 28, a lead screw connecting seat 33 on the main base plate 31 for fitting the lead screw nut 26 and moving therewith, a proximity switch sensor 34 on the lead screw connecting seat 33, a positioning post 36 on the main base plate 31 for fixing the lead screw connecting seat 33, a limiting block 37 on the main base plate 31 for limiting the main base plate 31, and two buffer pads 38 on the limiting block 37 for buffering. The connecting parts of the upper slide assembly 3 mainly cooperate with the guide rail base assembly 2. Firstly, the fixing method is that the lead screw connecting... The seat 33 includes an annular slot, in which the lead screw nut 26 is inserted and fastened to the connecting flange face 261 and the connecting hole of the lead screw connecting seat 33. After the connection is fixed, the lead screw connecting seat 33 can move with the lead screw nut 26. The slider 32 is disposed on the slide rail 28 and plays a stabilizing and supporting role when the lead screw connecting seat 33 moves. The limiting block 37 and the buffer pad 38 are located between the two limit switches 212. The limit switches 212 limit the movement distance of the limiting block 37, which in turn limits the movement distance of the upper slide assembly 3. The proximity switch sensing piece 34 corresponds to the proximity switch 210 and moves according to the upper slide assembly 3. Figure 4 When the direction moves to the left, the proximity switch sensing element 34 gradually approaches the proximity switch 210 until the set position is reached, at which point the proximity switch 210 sends out a signal, the motor 24 stops rotating, and the upper slide assembly 3 no longer moves to the left; Figure 5 As shown in the embodiment of this application, there are four sliders 32, which are evenly distributed to connect the two slide rails 28 to play a role in stabilization and support.

[0039] Please refer to Figure 7 The schematic diagram of the positioning fixture assembly in this application shows that the feeding and detection device also includes a positioning fixture assembly 5. The positioning fixture assembly 5 is used to place the workpiece. For different workpieces, only the positioning fixture assembly 5 needs to be replaced, which saves equipment costs. The positioning fixture assembly 5 includes a fixture base plate 51 for carrying the workpiece, a fixture base plate support plate 52 set on the main machine base plate 31 for supporting the fixture base plate 51, and a plurality of positioning blocks 53 set on the fixture base plate 51 for positioning the workpiece. Figure 7 Each workpiece is positioned using four positioning blocks 53. The workpiece can be placed by a robotic arm or manually. Figure 6In this process, multiple main base plate through holes are opened on the main base plate 31, and support plate through holes are also opened on the tooling base plate support plate 52. When connected, fasteners fix the positioning tooling assembly 5 to the main base plate 31 through the main base plate through holes and support plate through holes. When the main base plate 31 moves, it drives the positioning tooling assembly 5 to move, so the workpiece placed on the tooling base plate 51 also moves.

[0040] Please refer to Figure 8 The schematic diagram of the frame assembly in this application shows that the feeding and detection device further includes a frame assembly 1. The frame assembly 1 includes a frame frame 11 for bearing load, four rollers 17 mounted on the frame frame 11 for movement, and four fixing brackets 16 mounted on the frame frame 11 for fixing. Figure 1 In this process, the movable lifting detection assembly 4 and the guide rail base assembly 2 are mounted on the frame 11. Four rollers 17 located below the frame 11 facilitate the movement of the loading detection device. After being moved into position, the loading detection device is fixed in place by the four fixing brackets 16 to increase the stability of the process.

[0041] The process flow of the device in this application is as follows:

[0042] 1. The workpiece is placed on the positioning fixture assembly 5;

[0043] 2. The motor 24 drives the lead screw 25 to rotate;
