Description

Technical Field

[0001] This application relates to the field of electric drive lifting technology for battery processing, specifically an electric drive lifting machine. Background Technology

[0002] In lithium battery production lines, battery unpacking and repacking are common processes. To ensure that batteries do not fall during handling, they are usually lifted from the material frame, exposing a portion of it so that the clamps can hold them securely.

[0003] Chinese Patent (Announcement No.: CN108199070A) discloses a lifting and positioning structure for a battery pack. The lifting mechanism in the above document uses a cylinder as a driving device, and controls the extension and retraction of the cylinder through a solenoid valve or a pneumatic control valve. However, the extension rod of the cylinder is easily damaged when subjected to large lateral forces, so it needs to be used in conjunction with a guide rail. In addition, due to the instability of high-pressure air, it is difficult for the cylinder to achieve precise stroke control. Therefore, an electric-driven lifting machine is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an electrically driven lifting machine that has advantages such as stable lifting and solves the problem of instability.

[0005] To achieve the above objectives, this application provides the following technical solution: an electric-driven lifting machine, including a material frame, two pillars fixed to the lower end of the material frame, a base plate fixed to the lower end of the two pillars, a lifting platform provided between the base plate and the material frame, the lifting platform including a lifting platform, multiple lifting rods and multiple rubber pads, and the interior of the lifting platform is provided with a lifting structure for driving it to move up and down;

[0006] The lifting structure includes four support plates. The top ends of the two inner support plates are rotatably connected to two screws via bearings. The outer surfaces of the left and right sets of screws are threaded with two sets of ball nuts. The top ends of the two outer support plates are fixed with two guide rails. The outer surfaces of the guide rails are slidably connected with ball sliders. The lifting structure also includes a drive structure disposed on the outer surfaces of the left and right sets of screws.

[0007] By adopting the above technical solution, precise control of the lifting platform is achieved through two stepper motors and a screw, ensuring that the battery is lifted to the required height. This allows for precise control of the stroke. Furthermore, the screw and guide rail improve the load-bearing capacity and movement stability of the lifting platform. The stepper motors and screw have a long service life, low maintenance costs, and a simple structure, making them easy to repair and reducing maintenance costs. In addition, the stepper motors have a high response speed, enabling them to quickly respond to control system commands and improve battery production efficiency.

[0008] Furthermore, two connecting holes are provided at both ends of the top of the lifting platform for ball nuts to pass through, and the ball nuts are fixed inside the connecting holes.

[0009] By adopting the above technical solution, the two sets of ball nuts can be fixed inside the lifting platform through the connecting holes, so that the left and right sets of screws are threadedly connected to the ball nuts. When the left and right sets of ball nuts move up and down, the left and right sets of ball nuts can drive the lifting platform to move, so that the lifting rod can push the battery out of the material frame.

[0010] Furthermore, two connecting holes are provided at both ends of the top of the lifting platform for the ball bearing slider to pass through, and the ball bearing slider is fixed inside the connecting holes.

[0011] By adopting the above technical solution, the left and right sets of ball sliders can be fixed inside the lifting platform through the connecting holes. When the ball nut drives the lifting platform to move up and down, the lifting platform can slide on the left and right guide rail surfaces through the left and right sets of ball sliders, so as to ensure that the lifting platform can move stably in the vertical direction.

[0012] Furthermore, the drive structure includes two concave support plates fixed to the lower end of the base plate, a stepper motor fixed to the lower end of the concave support plates, a main sprocket fixed to the output end of the stepper motor, and the drive structure also includes slave sprockets fixed to the outer surfaces of the left and right sets of screws, with chains meshing on the outer surfaces of the two slave sprockets and the main sprocket on the same side.

[0013] The above technical solution is adopted so that the left and right sets of screws can be driven to rotate accurately and quickly.

[0014] Furthermore, the bottom end of the concave support plate is provided with a rotating hole for the stepper motor to pass through and rotate inside it.

[0015] The above technical solution is adopted so that the output end of the stepper motor can drive the main sprocket to rotate inside the concave support plate, so that the concave support plate can support the stepper motor and also ensure the rotation of the main sprocket.

[0016] Furthermore, the chain is rotatably connected to the inner side of the concave support plate, and the stepper motor is located between two screws on the same side and two guide rails in the same group.

[0017] The above technical solution is adopted so that the chain can be connected to the main sprocket located inside the concave support plate, so that the stepper motor can drive the two slave sprockets to rotate through the main sprocket and the chain, thereby driving the two screws to rotate.

[0018] Furthermore, the bottoms of the multiple lifting rods are evenly distributed and fixed to the top of the lifting platform. A rubber pad is fitted onto the outer surface of the top of the lifting rod. A circular plate is fixed to the top wall of the inner side of the rubber pad, and a threaded rod is fixed to the lower end of the circular plate.

[0019] The above technical solution is used to form a lifting platform.

[0020] Furthermore, the top end of the lifting rod is provided with a threaded slot, and the threaded rod is threadedly connected to the inside of the material slot.

[0021] The above technical solution allows the rubber pad to be installed on the surface of the top of the lifting rod, thereby reducing wear and tear on the battery pack's appearance caused by the lifting rod, protecting the battery surface, and facilitating the replacement of the rubber pad.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This electrically driven lifting machine achieves precise control of the lifting platform through two stepper motors and a screw, ensuring that the battery is lifted to the required height. This allows for precise control of the stroke. The screw and guide rails improve the load-bearing capacity and movement stability of the lifting platform. The stepper motors and screw have a long service life, low maintenance costs, and a simple structure, making them easy to repair and reducing maintenance costs. Furthermore, the stepper motors have a high response speed, enabling them to quickly respond to control system commands and improve battery production efficiency. Attached Figure Description

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Please see Figure 1 and Figure 3 An electric-driven lifting machine in this embodiment includes a material frame 1. Two support columns 2 are fixed to the lower end of the material frame 1. A base plate 3 is fixed to the lower end of the two support columns 2. A lifting platform is provided between the base plate 3 and the material frame 1. The lifting platform includes a lifting platform 41, multiple lifting rods 42 and multiple rubber pads 43. The interior of the lifting platform 41 is provided with a lifting structure for driving it to move up and down.

[0030] Furthermore, the bottoms of multiple lifting rods 42 are evenly distributed and fixed to the top of the lifting platform 41. A rubber pad 43 is sleeved on the outer surface of the top of the lifting rod 42. A circular plate 431 is fixed on the top wall of the inner side of the rubber pad 43. A threaded rod 432 is fixed at the lower end of the circular plate 431.

[0031] Furthermore, the top of the lifting rod 42 is provided with a threaded slot, and the threaded rod 432 is threaded into the inside of the material slot, which makes it easy to fit and fix the rubber pad 43 onto the outer surface of the top of the lifting rod 42. This reduces the wear caused by the lifting rod 42 on the appearance of the battery pack, protects the battery surface, and facilitates the replacement of the rubber pad 43. The rubber pad 43 is a high-temperature resistant and wear-resistant silicone rubber pad with a thickness of 5 mm.

[0032] Please see Figures 1 to 2 The lifting structure in this embodiment includes four support plates 51. The top ends of the two inner support plates 51 are rotatably connected to two screws 52 via bearings. The outer surfaces of the left and right sets of screws 52 are threaded with two sets of ball nuts 53. The top ends of the two outer support plates 51 are fixed with two guide rails 54. The outer surfaces of the guide rails 54 are slidably connected with ball sliders 55. The lifting structure also includes a drive structure disposed on the outer surfaces of the left and right sets of screws 52.

[0033] The top of the lifting platform 41 has two connecting holes at its left and right ends for ball nuts 53 to pass through. The ball nuts 53 are fixed inside the connecting holes, so that the two sets of ball nuts 53 can be fixed inside the lifting platform 41 through the connecting holes. This allows the left and right sets of screws 52 to be threadedly connected to the ball nuts 53. When the left and right sets of ball nuts 53 move up and down, the left and right sets of ball nuts 53 can drive the lifting platform 41 to move, so that the lifting rod 42 can push the battery out of the material frame 1.

[0034] Furthermore, two connecting holes are provided at the left and right ends of the top of the lifting platform 41 for the ball sliders 55 to pass through. The ball sliders 55 are fixed inside the connecting holes, so that the left and right sets of ball sliders 55 can be fixed inside the lifting platform 41 through the connecting holes. When the ball nut 53 drives the lifting platform 41 to move up and down, the lifting platform 41 can slide on the surfaces of the left and right guide rails 54 through the left and right sets of ball sliders 55, so as to ensure that the lifting platform 41 can move stably in the vertical direction.

[0035] Furthermore, two distance sensors are fixed to the top of the base plate 3 to ensure that the range of movement of the lifting platform 41 is detected, so as to prevent the lifting platform 41 from exceeding the safe range.

[0036] It should be noted that screw 52 is a ball screw made of 45 steel, with a diameter of 16 mm and a pitch of 2 mm; ball nut 53 is made of 45 steel; and guide rail 54 is a linear guide rail, model LM-20.

[0037] Please see Figures 1 to 2 In this embodiment, the driving structure includes two concave support plates 57 fixed to the lower end of the base plate 3. A stepper motor 56 is fixed to the lower end of the concave support plate 57. A main sprocket 581 is fixed to the output end of the stepper motor 56. The driving structure also includes slave sprockets 582 fixed to the outer surfaces of the left and right sets of screws 52. A chain 583 meshes with the outer surfaces of the two slave sprockets 582 and the main sprocket 581 on the same side.

[0038] Secondly, the bottom end of the concave support plate 57 is provided with a rotating hole for the stepper motor 56 to pass through and rotate inside it, so that the output end of the stepper motor 56 can drive the main sprocket 581 to rotate inside the concave support plate 57, so that the concave support plate 57 can support the stepper motor 56 while also ensuring the rotation of the main sprocket 581.

[0039] Furthermore, the chain 583 is rotatably connected to the inner side of the concave support plate 57 so that the chain 583 can be connected to the main sprocket 581 located inside the concave support plate 57, and the stepper motor 56 is located between the two screws 52 on the same side and the two guide rails 54 in the same group.

[0040] Furthermore, the stepper motor 56, model XYZ-123, features high precision and high response speed.

[0041] It should be noted that all electronic components mentioned in this article are commonly known in the prior art, and the control method of this embodiment is controlled by a controller. All electrical components mentioned in this article are connected to the controller and power supply. The control circuit of the controller can be implemented by those skilled in the art through simple programming. Furthermore, the controller controls two stepper motors 56 to work synchronously through a synchronous control system. The synchronous control system is also commonly known in the prior art, so this utility model will not explain the control method and circuit connection in detail.

[0042] The working principle of the above embodiments is as follows:

[0043] In use, the controller controls two stepper motors 56 to work simultaneously through a synchronous control system. The two stepper motors 56 simultaneously drive the two main sprockets 581 to rotate in the same direction. The two main sprockets 581, through the chain 583, can simultaneously drive the left and right sets of driven sprockets 582 to rotate. This allows the left and right sets of driven sprockets 582 to drive the left and right sets of screws 52 to rotate in the same direction. The left and right sets of screws 52 are threadedly connected to the left and right sets of ball nuts 53, allowing the two sets of screws 52 to drive the two sets of ball nuts 53 to move upward. This allows the two sets of ball nuts 53 to drive the lifting platform upward. When the lifting platform moves upward, its lifting platform 41 drives the left and right sets of ball sliders 55 to slide upward on the surfaces of the left and right sets of guide rollers 54 to ensure the stability of the lifting platform during movement. This allows the multiple lifting rods 42 of the lifting platform to push the batteries out of the material frame 1.

[0044] Compared with the prior art, this application achieves precise control of the lifting platform through two stepper motors 56 and a screw 52, ​​ensuring that the battery lifting height meets the requirements, so as to accurately control the stroke. Furthermore, the screw 52 and guide rail 54 improve the load-bearing capacity and movement stability of the lifting platform. The stepper motors 56 and screw 52 have long service life, low maintenance cost, and simple structure, making them easy to repair, thereby reducing maintenance costs. In addition, the stepper motors 56 have high response speed, which can quickly respond to control system commands and improve battery production efficiency.
