[0050] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0051] like Figures 1-6 As shown, a casing stamping device includes a frame, a conveyor line 1, at least one lifting and rotating device 2, a pressing device 3 corresponding to the lifting and rotating device 2, and a stamping device 4 corresponding to the lifting and rotating device 2.

[0052] The conveyor line 1 is provided with a working position corresponding to the lifting and rotating device 2. The conveyor line 1 is used to transport the pallet carrying the shell to the working position.

[0053] The lifting and rotating device 2 is connected to the frame and is used to lift the pallet that is conveyed to the corresponding working position and drive the pallet to rotate. The lifting and rotating device 2 is also used to put the lifted pallet back onto the conveyor line 1.

[0054] The pressing device 3 is connected to the frame and is used to press down on the housing on the tray supported by the corresponding lifting and rotating device 2;

[0055] The stamping device 4 is connected to the frame and is used to stamp the casing on the tray supported by the corresponding lifting and rotating device 2.

[0056] Specifically, firstly, conveyor line 1 transports the pallet carrying the casing to the working position. Then, lifting and rotating device 2 lifts the pallet at the corresponding working position and rotates it to a suitable angle so that the position on the casing that needs to be stamped faces the corresponding stamping device 4. Next, pressing device 3 presses the casing on the pallet lifted by lifting and rotating device 2 down onto the pallet to prevent the casing from shaking during stamping. Then, stamping device 4 stamps the casing on the pallet lifted by lifting and rotating device 2. After stamping, stamping device 4 returns to its original position, pressing device 3 releases the pressed casing, and lifting and rotating device 2 rotates the pallet back to its initial angle and places it back on conveyor line 1. Conveyor line 1 then transports the pallet carrying the casing to the next process to complete the casing unloading. Throughout the entire process, the loading and unloading of the machine casing is automatically completed by the conveyor line 1, achieving automatic stamping on the machine casing without manual operation, greatly reducing labor costs and improving production efficiency. In this embodiment, the lifting and rotating device 2, the pressing device 3, the stamping device 4, and the working position are each provided in twos, with the pressing device 3, the stamping device 4, and the working position corresponding one-to-one with the lifting and rotating device 2. The conveyor line 1 can be a double-speed chain.

[0057] like Figure 2 , 3 As shown, the pressing device 3 may include a pressing cylinder 5, a pressing base 6, and a pressing block 7;

[0058] The lower pressure seat 6 is slidably connected to the frame in the vertical direction;

[0059] The pressure block 7 is connected to the lower pressure seat 6;

[0060] The pressing cylinder 5 is connected to the frame and is connected to the pressing seat 6. The pressing cylinder 5 drives the pressing seat 6 to slide downwards, thereby moving the pressing block 7 downwards to press against the machine casing on the tray supported by the corresponding lifting and rotating device 2. Specifically, the process of the pressing device 3 pressing the machine casing downwards is as follows: after the lifting and rotating device 2 lifts the tray in the corresponding working position and rotates the tray to a suitable angle, the pressing cylinder 5 drives the pressing seat 6 to slide downwards, thereby moving the pressing block 7 downwards so that the pressing block 7 presses against the machine casing on the tray supported by the corresponding lifting and rotating device 2. At this time, the machine casing is pressed firmly onto the tray by the pressing block 7, preventing the casing from shaking during stamping. After stamping is completed, the pressing cylinder 5 drives the pressing seat 6 to rise upwards, thereby raising the pressing block 7 to release the pressed machine casing.

[0061] like Figure 2 , 3As shown, the lower pressure seat 6 may include an upper connecting plate 8, a lower connecting plate 9, a mounting plate 10, multiple guide posts 11, and multiple connecting posts 12;

[0062] The upper end of the guide post 11 is connected to the upper connecting plate 8;

[0063] The lower end of the guide post 11 is connected to the lower connecting plate 9;

[0065] The upper end of the connecting column 12 is connected to the lower connecting plate 9;

[0066] The mounting plate 10 is connected to the lower end of the connecting post 12;

[0067] The pressure block 7 is connected to the mounting plate 10;

[0068] The lowering cylinder 5 is connected to the frame and to the lower connecting plate 9, and is used to drive the lower connecting plate 9 to move up and down, thereby driving the entire lowering seat 6 to move up and down. In this embodiment, the frame includes an upper frame and a lower frame. The upper frame is connected to the lower frame through a column, and the guide column 11 is slidably connected to the upper frame.

[0069] Specifically, the pressure block 7 is a flexible rubber block, which can prevent damage to the machine casing.

[0070] like Figure 2 , 4 As shown, the stamping device 4 may include a movable base 13, a lifting base 14, a movable drive assembly 15, a lifting drive assembly 16, and a pneumatic stamping machine 17.

[0071] The movable seat 13 is slidably connected to the frame;

[0072] The mobile drive assembly 15 is connected to the frame and to the mobile base 13 and is used to drive the mobile base 13 to move toward or away from the corresponding lifting and rotating device 2.

[0073] The lifting seat 14 is slidably connected to the movable seat 13 in the vertical direction;

[0074] The lifting drive assembly 16 is connected to the movable seat 13 and connected to the lifting seat 14, and is used to drive the lifting seat 14 to move up and down.

[0075] The pneumatic stamping machine 17 is connected to the lifting base 14 and is used to stamp on the housing on the tray supported by the corresponding lifting and rotating device 2.

[0076] Specifically, the working process of the stamping device 4 is as follows: after the lifting and rotating device 2 lifts the tray in the corresponding working position and drives the tray to rotate to a suitable angle, the corresponding pressing device 3 will press down on the housing on the tray lifted by the corresponding lifting and rotating device 2. Then, the lifting drive assembly 16 will drive the lifting seat 14 to move up and down, thereby driving the pneumatic stamping machine 17 on the lifting seat 14 to move up and down to a suitable height. Then, the moving drive assembly 15 will drive the moving seat 13 to move towards the corresponding lifting and rotating device 2, thereby driving the pneumatic stamping machine 17 to move towards the corresponding lifting and rotating device 2. Then, the pneumatic stamping machine 17 can stamp on the housing on the tray lifted by the corresponding lifting and rotating device 2. After the steel stamping is completed, the moving drive assembly 15 drives the moving seat 13 to move away from the corresponding lifting and rotating device 2 back to the origin, thereby driving the pneumatic steel stamping machine 17 away from the corresponding lifting and rotating device 2. Then, the corresponding pressing device 3 releases the clamped housing, and the lifting and rotating device 2 drives the tray to rotate back to the initial angle and place the tray back onto the conveyor line 1. More specifically, the moving drive assembly 15 and the lifting drive assembly 16 can each be a linear module; the pneumatic steel stamping machine 17 is also called a pneumatic marking machine, and its specific structure is existing technology well known to those skilled in the art, and will not be described in detail in this embodiment.

[0077] like Figure 5 , 6 As shown, the lifting and rotating device 2 may include a lifting seat 18, a rotating seat 19, a lifting drive assembly, and a rotating drive assembly;

[0078] The lifting seat 18 is slidably connected to the frame in the vertical direction;

[0079] The rotating seat 19 is rotatably connected to the lifting seat 18 and is located above the lifting seat 18;

[0080] The lifting drive assembly is connected to the frame and to the lifting seat 18. The lifting drive assembly is used to drive the lifting seat 18 to rise, thereby driving the rotating seat 19 to rise so that the rotating seat 19 lifts the pallet that is being transported to the corresponding working position. The lifting drive assembly is also used to drive the lifting seat 18 to fall, thereby driving the rotating seat 19 to fall so that the pallet lifted by the rotating seat 19 is placed back onto the conveyor line 1.

[0081] The rotary drive assembly is connected to the lifting seat 18 and is used to drive the rotating seat 19 to rotate.

[0082] Specifically, the process of the lifting and rotating device 2 lifting the pallet and driving the pallet to rotate is as follows: After the conveyor line 1 transports the pallet carrying the machine casing to the corresponding working position, the lifting drive assembly drives the lifting seat 18 to rise, thereby driving the rotating seat 19 to rise so that the rotating seat 19 lifts the pallet in the corresponding working position. Then, the rotation drive assembly drives the rotating seat 19 to rotate, thereby driving the pallet to rotate so that the machine casing on the pallet rotates to a suitable angle. At this time, the position on the machine casing that needs to be stamped faces the corresponding stamping device 4. Then, the corresponding pressing device 3 will press down on the machine casing on the pallet on the corresponding rotating seat 19, and then the corresponding stamping device 4 will stamp on the machine casing. More specifically, the process of the lifting and rotating device 2 lowering the pallet is as follows: after the steel stamping is completed, the corresponding pressing device 3 will release the housing, and then the rotation drive assembly will drive the rotating seat 19 to rotate back to the initial angle. Then the lifting drive assembly will drive the lifting seat 18 to descend, thereby driving the rotating seat 19 to descend so that the pallet lifted by the rotating seat 19 can be placed back on the conveyor line 1. Then the conveyor line 1 will transport the pallet carrying the housing to the next process.

[0083] like Figure 5 , 6 As shown, the lifting and rotating device 2 may also include a pad block 20 and a moving cylinder 21;

[0084] The pad 20 is slidably connected to the frame;

[0085] The movable cylinder 21 is connected to the frame and is connected to the pad 20. The movable cylinder 21 is used to drive the pad 20 to move below the lifting seat 18 after the lifting drive assembly drives the lifting seat 18 to rise. Specifically, when the pressure block 7 in the pressing device 3 presses down on the housing on the tray, the downward pressure is transmitted through the housing to the tray and then to the rotating seat 19 and the lifting seat 18, which in turn presses the lifting seat 18 down on the pad 20. At this time, the pad 20 can provide upward support for the lifting seat 18.

[0086] like Figure 5 , 6 As shown, at least two positioning pins 22 are connected to the rotating base 19 for insertion into the positioning holes in the tray; specifically, the positioning pins 22 can be used to position the tray held on the rotating base 19.

[0087] like Figure 5 , 6 As shown, the rotary drive assembly may include a drive motor 23 and a drive gear 24;

[0088] The rotating seat 19 is rotatably connected to the lifting seat 18 via a turntable bearing, the turntable bearing including an inner ring 25 and an outer ring 26.

[0089] The inner ring 25 of the bearing is connected to the lifting seat 18, the outer ring 26 of the bearing is rotatably connected to the inner ring 25 of the bearing, the rotating seat 19 is connected to the outer ring 26 of the bearing, and the outer ring 26 of the bearing is provided with a gear portion 27.

[0090] The drive motor 23 is connected to the lifting seat 18, and the drive gear 24 is connected to the output shaft of the drive motor 23 and meshes with the gear part 27. When the drive motor 23 drives the drive gear 24 to rotate, it can drive the outer ring 26 of the bearing to rotate, which in turn can drive the rotating seat 19 to rotate. The drive motor 23 can be a servo motor.

[0091] Specifically, the lifting drive assembly includes a lifting cylinder 28, which is connected to the frame and the lifting seat 18 and is used to drive the lifting seat 18 to move up and down; in this embodiment, the lifting drive assembly includes two lifting cylinders 28.

[0092] like Figure 1 , 2 As shown, the conveyor line 1 is connected to a detection sensor 29 that corresponds to the working position and is used to detect whether there is a tray in the corresponding working position; in this embodiment, the detection sensor 29 corresponds one-to-one with the working position.

[0093] In summary, firstly, conveyor line 1 transports the pallet carrying the casing to the working position. Then, the lifting and rotating device 2 lifts the pallet at the corresponding working position and rotates it to a suitable angle so that the position on the casing that needs to be stamped faces the corresponding stamping device 4. Next, the pressing device 3 presses the casing on the pallet lifted by the lifting and rotating device 2 down onto the pallet to prevent the casing from shaking during stamping. Then, the stamping device 4 stamps the casing on the pallet lifted by the lifting and rotating device 2. After stamping, the stamping device 4 returns to its original position, the pressing device 3 releases the pressed casing, and the lifting and rotating device 2 rotates the pallet back to its initial angle and places it back on conveyor line 1. Conveyor line 1 then transports the pallet carrying the casing to the next process to complete the casing unloading. Throughout the entire process, the loading and unloading of the machine casing is automatically completed by conveyor line 1, which realizes automatic steel stamping on the machine casing without manual operation, greatly reducing labor costs and improving production efficiency.
