Description

Technical Field

[0001] The utility model belongs to the technical field of new energy battery processing, and in particular relates to an automatic pole coil transfer loading and unloading device. Background Art

[0002] In the new energy market, the width of the electrode rolls coated and rolled by lithium battery manufacturers has increased from 1000mm to 1200mm and is still increasing, challenging 1500mm or even higher. At present, the leading new energy companies have achieved 1500mm wide electrode roll coating and rolling in mass production lines. At the same time, the ability to continuously roll electrode rolls through coating and rolling is also constantly improving.

[0003] Therefore, the weight of the coating and winding rolls is getting heavier, and the difficulty of loading and unloading increases and the safety decreases. The loading and unloading methods used for coating and roller pressing are mostly manual loading. Due to the rigidity and positioning problems of the equipment itself, the actual deviation is often large, resulting in inadequate clamping and misalignment, causing material falling accidents. Specifically, the roll of material such as coating is wound on a reel. The reel after winding is not only bulky, but also requires manual assistance during the installation process of the air shaft on the processing equipment platform to connect the two ends of the reel on the reel to the air shaft on the platform. During the operation of the machine, the air shaft drives the unwinding of the roll.

[0004] However, during the material loading and coiling process, due to the heavy weight of the coil, it is not only difficult to lift it, but also difficult to maintain the correct posture to dock it on the air shaft.

[0005] Therefore, in order to assist in loading, the current conventional practice is to use a hoist to lift the coil and then connect it to the air shaft.

[0006] However, by the same token, the lifting method makes it difficult to keep the coil at a high level and maintain precise posture docking.

[0007] Similarly, when the machine has completed unwinding, the empty roll needs to be detached from the air shaft. However, it is very difficult to detach the heavy and large-diameter empty roll. This is reflected in the fact that since the machine and the air shaft have a certain height, when the air shaft detaches from the empty roll, it is difficult to lower the roll in a safe and stable manner.

[0008] Therefore, in the actual working process, safety accidents such as the roll and coil falling often occur. Once the roll falls, the quality of the roll will be damaged and it will be treated as waste or the equipment will be damaged, causing economic losses, or even causing personal injuries. Manual loading is unsafe. Utility Model Content

[0009] Based on the above background, the purpose of the utility model is to provide a pole coil automatic transfer loading and unloading device.

[0010] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0011] An automatic transfer loading and unloading device for pole coils, comprising a mobile trolley, the top of which is connected to a plurality of lifting mechanisms arranged at intervals; the lifting mechanisms comprise lifting components arranged on both sides;

[0012] The lifting assembly includes a mounting seat mounted on a mobile trolley;

[0013] The lifting assembly further comprises a lifting seat slidably connected to the mounting seat, and both ends of the lifting seat are integrally formed with upwardly protruding blocking arms; the side walls of the blocking arms facing each other are inclined surfaces;

[0014] The inclined surface structure and the top surface of the lifting seat form a V-shaped discharge portion;

[0015] The lifting assembly also includes a lifting cylinder installed at the bottom position of the lifting seat.

[0016] Preferably, the mounting seat comprises a vertical seat body and a horizontal assembly seat body fixedly connected to the bottom position of the vertical seat body; the lifting cylinder is installed at the lower end position of the vertical seat body.

[0017] Preferably, the mounting seat is detachably mounted on the top edge of the moving vehicle.

[0018] Preferably, the top of the piston rod of the lifting cylinder is fixedly connected to a bottom assembly seat, and the bottom of the lifting seat is fixedly assembled at the top position of the bottom assembly seat.

[0019] Preferably, a protruding assembly convex portion is integrally formed on the top of the bottom assembly seat, and a matching groove is formed on the bottom of the lifting seat;

[0020] The assembly protrusion is inserted into the groove.

[0021] Preferably, a cylinder fixing frame is fixedly connected to the top of the horizontal assembly seat body, and the cylinder barrel of the lifting cylinder is fixedly installed on the cylinder fixing frame.

[0022] Preferably, sliding openings are respectively provided at both ends of the lifting seat;

[0023] Both sides of the vertical seat body are fixedly connected with sliding tongues which are slidably connected in the sliding openings.

[0024] Preferably, a plurality of pressure sensors are fixedly connected to the top of the lifting seat;

[0025] The pressure sensor is located in the discharge part.

[0026] Preferably, the lifting cylinder is a three-axis cylinder, and the three piston rods on the lifting cylinder are fixedly connected to the bottom of the bottom assembly seat.

[0027] Preferably, the top of the movable trolley is connected to two lifting mechanisms arranged at intervals.

[0028] The utility model has the following beneficial effects:

[0029] 1. During the working process, first, the coil is loaded between the lifting seats on one lifting mechanism, and the other remains idle. At this time, the mobile trolley moves the coil to the bottom of the machine, and moves the idle lifting mechanism to the lifting seats on both sides corresponding to the positions of the air shafts on both sides of the machine. At this time, the lifting cylinder lifts the lifting seat to support the empty roll on the machine, and detaches from the air shaft on the machine, and then drives the lifting seat down through the lifting cylinder. At this time, the mobile trolley continues to move to the corresponding position, lifts the coil, and the air shaft on the machine docks with the roll shaft on the coil. At this time, the lifting seat descends, completing the process of unloading the empty roll and loading the coil.

[0030] This method not only saves effort in loading and unloading, but also can keep the empty reel and coiled material rising and falling steadily during the loading and unloading process, and the safety is very high during the lifting process, and the coiled material and empty reel are not easy to tip over, roll or slide, which not only greatly saves manpower and material resources and improves working efficiency, but also greatly improves work safety.

[0031] 2. Through the structural improvement of the lifting seat, specifically, the two ends of the lifting seat are integrally formed with upwardly protruding stop arm parts; a discharge part of the limited discharge reel is formed between the stop arm parts; specifically, the side walls of the stop arm parts facing each other are inclined structures; the inclined structure of the stop arm part and the top surface of the lifting seat form a V-shaped discharge part.

[0032] The lifting seat adopts the above-mentioned structural design to carry and limit the two ends of the empty reel and the coiled material in the unloading part. Under the support and isolation of the barrier arm part, the empty reel and the coiled material are prevented from sliding sideways and falling, thereby greatly improving the stability of the empty reel and the coiled material during the lifting process.

[0033] 3. Several pressure sensors are fixedly connected to the top of the lifting seat; the pressure sensors are located in the unloading section. Specifically, the pressure sensors are used to improve the safety of the operation. For example, when the roll is unloaded and enters the unloading section, the pressure sensor is used to determine whether the roll is stably loaded on the lifting seat, and similarly, whether the coil has been loaded on the lifting seat. In this way, the safety of the operation is improved to avoid lifting operations when the roll and coil are not fully loaded. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Example 1

[0044] like Figure 1-4 As shown, an automatic transfer and loading and unloading device for pole rolls includes a mobile trolley 1. The mobile trolley 1 is a movable trolley disclosed in the prior art, such as an AVG mobile trolley 1. During the working process, the mobile trolley 1 moves in the workshop to transport the coils (empty roll winding materials) and the empty rolls, and transport them to the machine 2 (i.e., the working equipment), unload the empty rolls 5 that have been unwound on the machine 2, and load the coils of winding materials onto the air shaft 21 on the machine 2.

[0045] Specifically, the top of the mobile trolley 1 is equipped with two spaced-apart lifting mechanisms (one for loading the coil and the other for receiving the empty roll 5 loaded and unloaded by the machine 2). Specifically, the lifting mechanism includes a lifting assembly 3 installed at both sides of the top of the mobile trolley 1. The lifting assembly 3 supports both sides of the coil or the empty roll 5 and realizes lifting.

[0046] Specifically, the lifting assembly 3 includes a mounting base 31 that can be detachably mounted on the moving trolley 1, and the mounting base 31 includes a vertical seat body and a horizontal assembly seat body 311 fixedly connected to the bottom position of the vertical seat body (the horizontal assembly seat body 311 is installed at the top edge position of the moving trolley 1 by means of bolt fastening, for example).

[0047] At the same time, the lifting assembly 3 also includes a lifting seat 34 slidably connected to the vertical seat body, and the shape of the lifting seat 34 is:

[0048] The lifting seat 34 has an upwardly protruding stop arm portion 341 integrally formed at both ends; a discharge portion 342 for limiting the discharge reel is formed between the stop arm portions 341; specifically, the side walls of the stop arm portions 341 facing each other are inclined structures; the inclined structure of the stop arm portion 341 and the top surface of the lifting seat 34 form a V-shaped discharge portion 342.

[0049] The lifting seat 34 with the above-mentioned structural design can carry and limit the two ends of the empty reel 5 and the coiled material in the discharge part. Under the support and isolation of the barrier arm part 341, the empty reel 5 and the coiled material are prevented from sliding sideways and falling, thereby greatly improving the stability of the empty reel 5 and the coiled material during the lifting process.

[0050] At the same time, the lifting assembly 3 also includes a lifting cylinder 33 installed at the lower end of the vertical seat body (the cylinder barrel is fixed in the following manner: a cylinder fixing frame 332 is fixedly connected to the top of the horizontal assembly seat body, and the cylinder barrel of the lifting cylinder 33 is fixedly installed on the cylinder fixing frame 332), and the piston rod of the lifting cylinder 33 is fixedly installed at the bottom of the lifting seat 34.

[0051] The top of the piston rod of the lifting cylinder 33 is fixedly connected to the bottom assembly seat 331, and the bottom of the lifting seat 34 is fixedly assembled at the top position of the bottom assembly seat 331. Specifically, in order to improve the assembly stability, the top of the bottom assembly seat 331 is integrally formed with a protruding assembly convex portion A, and the bottom of the lifting seat 34 is provided with an adaptive groove; the assembly convex portion A is inserted into the groove and fastened by, for example, bolts.

[0052] At the same time, in order to improve the stability and accuracy of the lifting seat 34 during the lifting process and ensure that the roll and the coil are accurately lifted to the two sides of the air shaft 21 of the machine 2, sliding openings are respectively opened at both ends of the above-mentioned lifting seat 34; correspondingly, sliding tongues 32 that are slidably connected to the sliding openings are fixedly connected on both sides of the vertical seat body.

[0053] During the lifting process, the lifting seat 34 lifts the hole reel and the coiled material in a relatively stable and accurate posture relative to the sliding tongue 32.

[0054] The operation process is as follows:

[0055] First, the coil is loaded between the lifting seats 34 on one lifting mechanism, and the other remains idle. At this time, the mobile trolley 1 moves the coil to the bottom of the machine 2, and moves the idle lifting mechanism to the lifting seats 34 on both sides corresponding to the positions of the air shafts 21 on both sides of the machine 2. At this time, the lifting cylinder 33 lifts the lifting seat 34 to support the empty roll 5 on the machine 2, and detaches from the air shaft 21 on the machine 2, and then drives the lifting seat 34 to descend through the lifting cylinder 33. At this time, the mobile trolley 1 continues to move to the corresponding position, lifts the coil, and the air shaft 21 on the machine 2 docks with the roll shaft on the coil. At this time, the lifting seat 34 descends, completing the process of unloading the empty roll 5 and loading the coil.

[0056] This method not only saves effort in loading and unloading, but also can keep the empty reel 5 and the coiled material rising and falling steadily during the loading and unloading process, and the safety is very high during the lifting process, and the coiled material and the empty reel 5 are not easy to tip over, roll or slide, which not only greatly saves manpower and material resources and improves working efficiency, but also greatly improves work safety.

[0057] Example 2

[0058] like Figure 1-4 As shown, based on the structure of Example 1, in order to increase the lifting load of the lifting cylinder 33, the lifting cylinder 33 adopts a three-axis cylinder disclosed in the prior art, and the three piston rods on the corresponding lifting cylinder 33 are fixedly connected to the bottom of the bottom assembly seat 331.

[0059] Example 3

[0060] like Figure 1-4 As shown, based on the structure of the first embodiment, in order to timely monitor whether the lifting seat 34 is loaded with an empty roll 5 or a coil, a plurality of pressure sensors 4 (the pressure sensors 4 are conventional pressure sensors disclosed in the prior art) are fixedly connected to the top of the lifting seat 34; the pressure sensors 4 are located in the unloading section. Specifically, the pressure sensors are used to improve the safety of the operation. For example, when the roll is unloaded and enters the unloading section, the pressure sensors are used to determine whether the roll is stably loaded on the lifting seat 34, and similarly, whether the coil has been loaded on the lifting seat 34. In this way, the safety of the operation is improved to avoid lifting and lowering operations when the roll or coil is not fully loaded.

[0061] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
