[0032] As shown in Figure 1 , Figure 2 , Figure 4 and Figure 7 , the one-way carriage 51 is fixedly connected to a cylinder at one end near the insertion rod 55; the insertion rod 55 is fixedly connected to a guide block at one end near the one-way carriage 51, and the guide block is in the shape of a tapered column; when the insertion rod 55 pushes the one-way carriage 51, the guide block is fixed at one end of the insertion rod 55 near the one-way carriage 51, and as the insertion rod 55 moves closer to the one-way carriage 51, the tapered column-shaped guide block is inserted into the cylinder to push the one-way carriage 51 to displace; this design of the tapered column-shaped guide block cooperating with the cylinder makes the pushing process more accurate and stable, and the guide block can gradually guide into the cylinder; at the same time, this design also improves the accuracy of the movement of the one-way carriage 51, ensuring the reliability of the interception and uninterception actions, and further improving the stability and full automation level of the entire packaging equipment.

[0033] Working process: when the motor assembly is packaged, the base 1 is used as the operation platform for packaging the motor assembly, the two fixed frames 11 are erected on the base 1 as supports, a first connecting plate 12 is fixed on a fixed frame 11 in cooperation with a first nozzle 13 and is located above the base 1, a bottom box 17 is first placed on the base 1, a first inner film bag 18 is fixed inside the bottom box 17, and the injection port of the first inner film bag 18 is connected with a first injection hole of the bottom box 17, the bottom box 17 is pushed to the first nozzle 13, and the first injection hole of the bottom box 17 corresponds to the output end of the first nozzle 13, an external pump is connected with the input pipe 16, at this time, the external pump draws the polyurethane mixed solution into the input pipe 16, through the opened electromagnetic valve 15 into the first conduit 14, then the polyurethane mixed solution is injected into the first inner film bag 18 through the first nozzle 13, the polyurethane mixed solution starts to react, according to different specifications of the motor assembly, different reaction times are set to put the motor assembly, during the reaction, the motor assembly is hoisted into the bottom box 17 by the crane, the polyurethane mixed solution continues to react until it is completely solidified, the motor assembly is firmly wrapped and fixed in the bottom box 17, the preliminary packaging of the motor assembly is completed, then the motor assembly after the preliminary packaging is moved to the rear end, the upper part of the bottom box 17 is closed and packaged, so as to realize the automatic packaging of the motor assembly; when the polyurethane mixed solution is injected into the first inner film bag 18, the injection pipe 2 is fixed at the bottom of the first inner film bag 18 in cooperation with a plurality of second nozzles 21, the injection port of the injection pipe 2 communicates with the injection port of the first inner film bag 18, after the output end of the first nozzle 13 is connected with the first injection hole of the bottom box 17, the polyurethane mixed solution is injected from the first injection hole of the bottom box 17 into the injection pipe 2, and then is uniformly distributed into the first inner film bag 18 by the plurality of second nozzles 21, so that the polyurethane mixed solution is more uniformly distributed in the first inner film bag 18, avoiding the situation that the local concentration is too high or too low, so as to ensure that the wrapping layer after the polyurethane foaming is uniform in quality, and further improve the packaging quality of the motor assembly; this uniform injection method also helps to speed up the reaction speed of the polyurethane mixed solution, shorten the packaging time, and improve the overall packaging efficiency; moreover, the design of the plurality of uniformly distributed second nozzles 21 can still maintain good injection uniformity when facing different sizes of the bottom box 17 and the motor assembly, and the adaptability of the packaging equipment to different types of motor assemblies is enhanced; When the motor assembly is hoisted, the support column 31 is supported at the base 1 in cooperation with the two suspension frames 3 and the two fixing frames 11, the first hydraulic cylinder 33 is connected to one of the suspension frames 3 through the electric sliding frame, the hoisting hook 35 is fixed above the motor assembly first, and the motor assembly is placed on the assembly seat 32 to wait for hoisting, the electric sliding frame drives the first hydraulic cylinder 33 to slide above the assembly seat 32, the first hydraulic cylinder 33 connects the hoisting hook 35 on the motor assembly in cooperation with the electric clamp 34, at this time the polyurethane mixed solution has been injected into the first inner film bag 18 to start the reaction, then the electric sliding frame hoists the motor assembly into the bottom box 17 and wraps the first inner film bag 18, this hoisting method uses the precise control of the electric sliding frame to realize the stable movement of the motor assembly in the packaging process, further guarantees the safety and packaging quality of the motor assembly; at the same time, the design of the assembly seat 32 provides a stable waiting hoisting platform for the motor assembly, ensures the accurate position of the motor assembly before hoisting, and improves the hoisting efficiency; in addition, the setting of the hoisting hook 35 enhances the connection stability between the motor assembly and the electric clamp 34, so that the motor assembly is not easy to fall off during hoisting, which improves the safety of the whole hoisting process, the hoisting hook 35 can be replaced and adapted according to different models, does not need to be taken off during transportation, and can be sent together with the motor assembly; through this automatic hoisting method, the whole packaging process is accelerated, which meets the high requirements of large-scale production on packaging efficiency;When the motor assembly is placed in the bottom box 17 matched with the first inner film bag 18, the bottom box 17 is pushed to one side of the upper cover table 4 on the machine base 1, and a box cover 45 is placed on the upper cover table 4 in advance. When the electric sliding frame drives the first hydraulic cylinder 33 to lift the motor assembly on the assembly seat 32, the electric sliding frame drives the second hydraulic cylinder 43 connected with the sliding block through the second connecting plate 42 to move synchronously, so that the vacuum suction seat 44 moves to the position above the box cover 45. Then the second hydraulic cylinder 43 cooperates with the vacuum suction seat 44 to vacuum the box cover 45. The vacuum suction seat 44 is connected to the vacuum pump. At this time, the first nozzle 13 connected with the first conduit 14 injects the polyurethane mixture into the second inner film bag 46 to foam. The electromagnetic valve 15 is an electric three-way valve. When the input pipe 16 injects the polyurethane mixture into the first conduit 14, the input pipe 16 is closed in the direction of the second conduit 47. Conversely, when the input pipe 16 injects the polyurethane mixture into the second conduit 47, the input pipe 16 is closed in the direction of the first conduit 14. Then the motor assembly is lifted to the position above the second bottom box 17, and the box cover 45 is lifted to the position above the first bottom box 17 at the same time. Then the first hydraulic cylinder 33 puts the motor assembly into the second bottom box 17, and the second hydraulic cylinder 43 also drives the box cover 45 to cover the first bottom box 17. The first nozzle 13 connected with the second conduit 47 is connected with the second injection hole of the box cover 45. The polyurethane mixture is injected into the second inner film bag 46 to react. The box cover 45 is tightly combined with the first bottom box 17 to form a closed structure. This design realizes the synchronous packaging and closing of the motor assembly, shortens the overall packaging time, and improves the continuity and efficiency of the packaging process. At the same time, the vacuum suction seat 44 can stably and accurately move the box cover 45, ensuring the position accuracy of the box cover 45 during lifting and placing, and avoiding packaging quality problems caused by placement deviation. Moreover, the design of the second conduit 47 connected with the electromagnetic valve 15 enables the injection path of the polyurethane mixture to be flexibly switched, meeting the demand for the injection position of the polyurethane mixture at different stages and improving the use flexibility and full automation degree of the equipment. In addition, this synchronous packaging and closing method reduces the exposure time of the motor assembly during packaging, reduces the risk of pollution and damage of the motor assembly caused by external factors, further improves the packaging quality and transportation safety of the motor assembly, and better meets the large-scale and high-efficiency motor assembly packaging production demand. Before injecting the mixture into the first inner film bag 18 and the second inner film bag 46, the two bottom boxes 17 are moved by mechanical pushing, and the two first nozzles 13 can accurately dock the two injection holes after the two bottom boxes 17 are positioned by the two first nozzles 13.With the movement of the electric slide, the two insertion rods 55 can push the first slide 51, which slides on the first fixed rail 5 and the fixed rod 52, and the elastic member 53 is pulled under stress. At this time, the two first slides 51 move away from the bottom box 17 to release the interception, and then the bottom box 17 can continue to be pushed to the designated position for subsequent operation. This positioning and release design ensures the accurate positioning of the bottom box 17 during the pushing process, avoids the problem of inaccurate docking of the injection hole due to positional deviation, thereby ensuring that the polyurethane mixed liquid can be smoothly injected into the first inner film bag 18 and the second inner film bag 46, and improving the accuracy and reliability of the packaging. At the same time, the sliding design of the first slide 51 on the first fixed rail 5 and the fixed rod 52, combined with the elastic action of the elastic member 53, enables the first slide 51 to move smoothly during the interception and release process. The fixed rod 52 can be provided with a damping structure that can be used to reduce the misalignment contact between the bottom box 17 and the first slide 51 when the bottom box 17 is continuously pushed. In addition, the two insertion rods 55 are respectively fixed to the bottom of the second connecting plate 42 and the extension plate 54, and are moved synchronously by the movement of the electric slide, thereby achieving the pushing of the first slide 51. This linkage design simplifies the operation process, improves the degree of full automation of the equipment, and makes the entire packaging process more efficient and smooth. When the two first slides 51 intercept the two bottom boxes 17, due to the different models of the packaged motor assemblies, the sizes of the used bottom boxes 17 are also different. The threaded rod 6 is threadedly connected to the first slide 51 and adjusts the position of the bottom box 17 intercepted by the intercepting plate 61, which can flexibly adjust the interception point according to the different sizes of the bottom box 17, ensuring that various models of the bottom box 17 can be accurately positioned. This adjustable interception design further enhances the adaptability of the packaging equipment to different models of motor assemblies, making the equipment more versatile when facing diversified production demands. When the motor assembly is fed onto the assembly seat 32, the insertion rod 55 at the bottom of the second connecting plate 42 can be displaced synchronously with the movement of the electric slide, and the second fixed rail 7 and the second slide 71 connected to the insertion rod 55 through the positioning pin 73 are also displaced synchronously, so that the limiting plate 72 can be moved to the motor assembly on the assembly seat 32 with the electric slide. When the limiting plate 72 contacts the motor assembly, the electric slide stops moving, and at this time the electric clamp 34 is accurately positioned above the lifting hook 35. This design uses the accurate positioning function of the limiting plate 72 to provide an accurate reference position for the electric slide to connect the lifting hook 35 with the electric clamp 34, ensuring that the electric clamp 34 can be accurately connected with the lifting hook 35 before lifting, and further improving the accuracy and efficiency of the lifting. At the same time, the second fixed rail 7 and the second slide 71 can adjust the position of the limiting plate 72 according to different models of the motor assembly through the insertion of the positioning pin 73, ensuring the accuracy of the positioning and quickly adapting to the positioning needs of different models of the motor assembly, enhancing the versatility and flexibility of the equipment. When loading different sizes of bottom boxes 17, the spacing between the two width limiting plates 8 is adjusted according to the size of the currently used bottom box 17, and then the bottom box 17 is placed between the two width limiting plates 8, the loading end of the width limiting plate 8 is provided with an open guide, and the conveyor 81 can drive the bottom box 17 to move between the two width limiting plates 8, which makes the equipment flexible to adapt to different sizes of bottom boxes 17, and ensures the stability and accuracy of the bottom box 17 during loading; At the same time, the setting of the conveyor 81 further enhances the stability of the bottom box 17 during movement, avoiding the problems of poor movement and deviation caused by size difference; In addition, the introduction of the adjusting assembly makes the spacing between the two width limiting plates 8 can be quickly adjusted according to actual needs, improves the operation convenience of the equipment, and can better meet the large-scale, diversified motor assembly packaging production demand; When adjusting the spacing between the two width limiting plates 8, first move the position of the width limiting plate 8, then use the positioning plate 9 to penetrate the width limiting plate 8 and insert into the plurality of adjusting holes 91, which can position the position of the width limiting plate 8, this adjustment method is simple and stable, by selecting the adjusting hole 91 inserted into different positions by the positioning plate 9, the spacing between the two width limiting plates 8 can be quickly and accurately determined, so as to adapt to the loading demand of different size bottom boxes 17; When the push rod 55 pushes the first carriage 51, the guide block is fixed at one end of the push rod 55 close to the first carriage 51, and as the push rod 55 moves close to the first carriage 51, the conical cylindrical guide block is inserted into the cylinder to push the first carriage 51 to displace, the cooperation design of the conical cylindrical guide block and the cylinder makes the pushing process more accurate and stable, and the guide block can be gradually guided into the cylinder; At the same time, this design also improves the accuracy of the movement of the first carriage 51, ensures the reliability of the interception and uninterception actions, and further improves the stability and full automation degree of the whole packaging equipment.
