The guide rods are inserted into the guide sleeves and cooperate with each other to guide the lifting seat 33.

[0023] The two side blocks form a sliding groove with the middle plate, and the sliding groove is located at the bottom of the middle plate; the connecting column assembly includes, from left to right, a first connecting column 331, a third connecting column 333, and a second connecting column 332, all three of which have a round block at their top that slides with the sliding groove; the first connecting column 331 passes through the first sliding plate 321 and connects to the first cover lifting assembly, the first sliding plate 321 is slidably connected to the sliding seat 32 and driven by the third driving mechanism 322, the third driving mechanism 322 including a second motor, a second lead screw driven by the second motor, and a mechanism cooperating with the second lead screw. The second nut is fixedly connected to the first sliding plate 321. The first sliding plate 321 moves laterally under the drive of the second motor. The bottom of the first sliding plate 321 is provided with a first fixed seat 34 and a third fixed seat 381 fixedly connected to it. The bottom of the first fixed seat 34 is provided with a first lower cover lifting unit 341. The first cover lifting assembly includes a first connecting block 35 slidably connected to the first fixed seat 34 and a first upper cover lifting unit 351 fixed to the bottom of the first connecting block 35. The first upper cover lifting unit 351 and the first lower cover lifting unit 341 form a first cover lifting head. The third connecting post 333 passes through the first sliding plate 321 and is connected to the third cover lifting assembly. The bottom of the first sliding plate 321 is provided with two third fixed seats 381. The third connecting post 333 and the third cover lifting assembly are located between the two third fixed seats 381. The third cover lifting assembly includes a third connecting block 38 slidably connected to the third fixed seat 381 and a third cover lifting head 382 fixed to the bottom of the third connecting block 38.

The second connecting post 332 passes through the second sliding plate 323 and connects to the second cover lifting assembly. The second sliding plate 323 is located at the bottom of the sliding seat 32 and is driven by the fourth driving mechanism 324. The fourth driving mechanism 324 includes a third motor, a third lead screw driven by the third motor, and a third nut that cooperates with the third lead screw. The third nut is fixedly connected to the second sliding plate 323. The second sliding plate 323 moves laterally under the drive of the third motor. The bottom of the second sliding plate 323 is provided with a second fixed seat 36 fixedly connected to it. The bottom of the second fixed seat 36 is provided with a second lower cover lifting unit 361. The second cover lifting assembly includes a second connecting block 37 slidably connected to the second fixed seat 36 and a second upper cover lifting unit 371 fixed to the bottom of the second connecting block 37. The second upper cover lifting unit 371 and the second lower cover lifting unit 361 form a second cover lifting head.

[0024] The workpiece 6 includes a main body and several upper covers 61 on the main body. The upper covers 61 form a cover hole 62 between the main body and the upper cover 61. The first cover head and the second cover head correspond to the two upper covers 61 on the left and right sides of the workpiece 6, respectively. The second cover head corresponds to the remaining upper covers 61 of the workpiece 6 excluding the two upper covers 61 on the sides. The manufacturer selects to set a second cover head at the bottom of the second connecting block 37 that matches the number of upper covers 61 of the workpiece 6 according to the actual situation. The lifting mechanism 3 descends under the drive of the first motor, and then the second and third motors cause the first lifting head, the second lifting head, and the third lifting head 382 to extend into their corresponding cover holes 62. The first motor continues to drive, causing the first lower lifting unit 341 and the second lower lifting unit 361 to contact the main body. That is, the first lower lifting unit 341 and the second lower lifting unit 361 abut against the bottom of the cover holes 62 on both sides of the main body, pressing down on the main body and preventing the entire workpiece 6 from being lifted during the lifting process. Then, driven by the first electric cylinder, the lifting seat 33 drives the connecting column assembly to rise. The first connecting column 331 drives the first upper lifting unit 351, the second connecting column 332 drives the second upper lifting unit 371, and the third connecting column 333 drives the third lifting head 382, ​​completing the lifting process. To facilitate the control and reading of the lateral movement distance of the first sliding plate 321 and the second sliding plate 323, the bottom of the sliding seat 32 is provided with a first scale for detecting the sliding distance of the first sliding plate 321 and a second scale for detecting the sliding distance of the second sliding plate 323.

[0025] like Figure 1 , 2 As shown in Figure 6, the conveying mechanism 4 includes a conveying frame 41, a conveying motor mounted on the conveying frame 41, a conveying chain driven by the conveying motor, and a tray mounted on the conveying frame 41; the base 12 is provided with a lifting mechanism 5 for lifting the workpiece 6, the lifting mechanism 5 includes a second electric cylinder 51 fixed on the base 12 and a lifting plate 52 driven by the second electric cylinder 51, the lifting plate 52 being fixedly connected to the push rod of the second electric cylinder 51.

[0026] The working principle of this invention is as follows: After the workpiece 6 is conveyed to the bottom of the cover-lifting mechanism 3, the second electric cylinder 51 pushes the lifting plate 52 to lift the workpiece 6; the sliding seat 32 descends vertically under the drive of the first motor. When the first cover-lifting head, the second cover-lifting head, and the third cover-lifting head 382 are all aligned with the cover hole 62, the second motor and the third motor drive the first sliding plate 321 and the second sliding plate 323 respectively, so that the first cover-lifting head, the second cover-lifting head, and the third cover-lifting head 382 enter the cover hole 62; the first motor continues to drive, so that the first lower cover-lifting unit 341 and the second lower cover-lifting unit 361 abut against the main body; the first electric cylinder is driven, so that the first upper cover-lifting unit 351, the second upper cover-lifting unit 371, and the third cover-lifting head 382 rise, thereby separating the upper cover 61 from the main body and completing the cover-lifting process. This invention completes the cover-lifting process by abutting against both sides of the workpiece 6, is applicable to multiple machine types, and can also prevent the workpiece 6 from being lifted during the cover-lifting process.
