[0017] This application also provides a method of using an aluminum alloy battery tray hot pressing forming equipment, comprising the following steps:

[0018] Step 1: Feed the aluminum alloy sheet into the loading box and start the conveyor belt to place the aluminum alloy sheet flat on the load-bearing plate.

[0019] Step 2: The feeding roller starts to feed the aluminum alloy plate into the guide box, and then the material roller sends the aluminum alloy plate out of the outlet.

[0020] Step 3: The material transfer unit supports the delivered aluminum alloy plate through the support plate.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-5In this embodiment of the invention, an aluminum alloy battery tray hot pressing forming equipment includes a processing table 1. A lower pressing mold 6 is embedded at one end of the top of the processing table 1, and an upper pressing mold 4 is correspondingly arranged above the lower pressing mold 6. A housing 2 is arranged above the processing table 1, and the upper pressing mold 4 is fixedly installed on the top of the inner wall of the housing 2. The bottom of the housing 2 is fixedly connected to the top edge of the processing table 1. A plurality of push springs are fixedly connected to the edge of the upper pressing mold 4, and a separation push plate 5 is fixedly connected to the bottom of the push springs. By setting the separation push plate 5, when the upper pressing mold 4 and the lower pressing mold 6 are separated, the separation push plate 5 pushes the aluminum alloy plate to separate from the upper pressing mold 4, thereby avoiding the adhesion of the hot-pressed aluminum alloy plate to the upper pressing mold 4 and affecting the subsequent transfer operation of the aluminum alloy plate.

[0034] Both sides of the lower die 6 are provided with material transfer units for moving the aluminum alloy plate. The material transfer unit includes a positioning groove. One end of the positioning groove is provided with an active groove 15 to facilitate the direct movement of the motor. The inner wall of the positioning groove is slidably connected to a support plate 11. The top of the support plate 11 away from the lower die 6 is folded up and tilted upwards. The depth of the positioning groove is consistent with the thickness of the support plate 11, so that when the support plate 11 is located in the positioning groove, its top surface is consistent with the top surface of the processing table 1, thus avoiding the presence of the support plate 11 from interfering with the hot pressing operation of the aluminum alloy plate.

[0035] A material transfer guide 12 is provided below the positioning groove. One side of the material transfer guide 12 is fixedly connected to the inner wall of the processing table 1. A mounting plate 13 is slidably connected to the inner wall of the material transfer guide 12. Several linear motors 14 are fixedly connected to the top of the mounting plate 13. The output ends of the several linear motors 14 are all fixedly connected to the bottom of the support plate 11. By setting up the material transfer guide 12 and linear motors 14, the support plate 11 is driven to rise, fall and move horizontally, thereby enabling the device to automatically complete the loading and unloading of aluminum alloy plates, improving the continuity of the device's operation and production efficiency.

[0036] Both sides of the lower pressing mold 6 are provided with vibration units for driving the lower pressing mold 6 to vibrate. The vibration unit includes a vibration box 7, a vibration motor is fixedly installed on the inner wall of the vibration box 7, an eccentric wheel is fixedly connected to the output end of the vibration motor, a heat insulation pad 8 is fixedly connected to one side of the vibration box 7, and one side of the heat insulation pad 8 is fixedly connected to the lower pressing mold 6. By setting up the vibration unit, vibration is applied to the aluminum alloy plate during the hot pressing process, so that the material dispersion and deformation of the aluminum alloy plate under pressure and heat are more uniform.

[0037] A pressing mechanism is provided below the lower die 6. The pressing mechanism includes a pressing guide rail 9. A support frame is slidably installed on the inner wall of the pressing guide rail 9. A pressing roller 10 is rotatably connected to the inner wall of the support frame. The top of the pressing roller 10 contacts the bottom of the lower die 6. Through the pressing mechanism, the aluminum alloy plate is rolled and pushed apart from below during the hot pressing process. With the help of the vibration unit, the aluminum alloy plate is easily dispersed.

[0038] A cooling unit for cooling the hot-pressed aluminum alloy plate is set in the middle of the processing table 1. The cooling unit includes two fan frames 19. The top of the fan frames 19 is inclined towards the middle of the processing table 1. The top of the fan frames 19 has an opening. A dust filter is fixedly connected to the inner wall of the opening. A cooling fan is fixedly installed on the inner wall of the fan frames 19. If the aluminum alloy plate is too hot, it will be difficult to move it in subsequent operations and it will also be easily deformed by external forces. When the hot-pressed aluminum alloy plate passes over the cooling unit, the cooling fan is activated to blow airflow onto the aluminum alloy plate to help it achieve rapid cooling and shaping, which will facilitate subsequent handling and contact.

[0039] To achieve automatic feeding of aluminum alloy sheets, a feeding mechanism for feeding aluminum alloy sheets is provided on one side of the processing table 1. The feeding mechanism includes a feeding box 27. A through groove is opened on one side of the feeding box 27. The width of the through groove is slightly larger than the thickness of the aluminum alloy sheet. Two symmetrically arranged load-bearing plates 29 are fixedly connected to one side of the through groove. Several feeding rollers 28 are rotatably connected to the bottom of the inner wall of the feeding box 27. Several friction pads are fixedly connected to the outer wall of the feeding rollers 28. The aluminum alloy sheet is pushed out of the through groove by the rotation of the feeding rollers 28.

[0040] Both sides of the inner wall of the feeding box 27 are rotatably connected to the whole material conveyor belt 30. The whole material conveyor belt 30 is set vertically. By rotating the whole material conveyor belt 30, friction is used to push and press the aluminum alloy plate, which helps the aluminum alloy plate enter the feeding box 27 and is stacked horizontally in sequence, which facilitates the pushing operation of the feeding roller 28.

[0041] A guide box 24 is fixedly connected to one side of the channel. Two sets of parallel material rollers 26 are rotatably installed on the inner wall of the guide box 24. A cavity is left between the two sets of material rollers 26 for the aluminum alloy plate to pass through. A discharge port 25 is opened at the end of the guide box 24 away from the feeding box 27.

[0042] To achieve automatic pushing and unloading of aluminum alloy plates after hot pressing, an unloading unit for discharging the hot-pressed aluminum alloy plates is provided at the other end of the top of the processing table 1. The unloading unit includes an unloading table 20, the top of which is inclined. Several guide rollers 23 are rotatably connected to the top of the unloading table 20. A pusher frame 21 is provided on one side of the unloading table 20. A pusher conveyor belt is rotatably installed on the inner wall of the pusher frame 21. A pusher plate 22 is fixedly connected to the surface of the pusher conveyor belt.

[0043] A detection frame 16 is fixedly installed at the end of the lower die 6 away from the unloading mechanism. A detection camera 17 is fixedly installed in the middle of the detection frame 16. The detection camera 17 is used to take pictures and identify the aluminum alloy plate from the side. A detection camera 28 is embedded on the top surface of the processing table 1 between the lower die 6 and the pusher 21. The detection camera 28 is used to take pictures and identify the aluminum alloy plate from the bottom after hot pressing. Through the cooperation of the detection camera 17 and the detection camera 28, the state of the aluminum alloy plate after hot pressing is detected and identified.

[0044] When using this application:

[0045] First, the aluminum alloy sheet is fed into the feeding box 27 manually or by external feeding equipment. The material conveyor belt 30 is started, so that the aluminum alloy sheet is placed flat on the support plate 29. The feeding roller 28 rotates to feed the aluminum alloy sheet into the guide box, and then the material conveyor roller 26 rotates to send the aluminum alloy sheet out from the discharge port 25. The aluminum alloy sheet is supported by two support plates 11. Then the material transfer guide rail 12 is started, which moves the support plates 11 and the aluminum alloy sheet to above the lower pressing mold 6. Then the linear motor 14 drives the support plates 11 to descend, so that the support plates 11 enter the positioning groove and the bottom surface of the aluminum alloy sheet is in contact with the lower pressing mold 6.

[0046] The upper die 4 starts pressing down, cooperating with the lower die 6 to hot press and shape the aluminum alloy plate. During the hot pressing process, the vibration units on both sides start, and the vibration motor drives the eccentric cam to rotate, which drives the lower die 6 to vibrate. At the same time, the push guide rail 9 drives the push roller 10 to move back and forth, pushing the lower die 6 to assist in shaping the aluminum alloy plate.

[0047] After the shaping is completed, the upper pressure mold 4 is reset, the linear motor 14 drives the support plate 11 to rise, lifting the aluminum alloy plate. Then, the transfer guide rail 12 drives the support plate 11 and the aluminum alloy plate to move above the pusher frame 21. The cooling fans of the cooling units on both sides start and blow airflow onto the aluminum alloy plate to help it achieve rapid cooling and shaping. The detection camera 17 and the detection camera 28 compare the images of the aluminum alloy plate from the side and bottom of the aluminum alloy plate with the preset images of the hot-pressed aluminum alloy plate through the external analysis equipment. When the deviation is too large, it is regarded as a defective product, and the operator is notified to remove the aluminum alloy plate. After the identification is passed, the pusher conveyor belt starts and drives the pusher plate 22 to move, pushing the aluminum alloy plate to the top of the unloading table 20. The guide roller 23 rotates to discharge the aluminum alloy plate.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
