Description

Technical Field

[0001] The utility model relates to the technical field of battery transportation, in particular to a lithium battery clamping and transferring device. Background Art

[0002] At present, due to a series of advantages such as long cycle life and light weight, lithium batteries are widely used in electric vehicles, communication power supplies, and energy storage fields. At the same time, the processing speed of battery production is also accelerating. Usually, during the battery production process, because the single body is large and heavy, the battery needs to be transferred using a turnover device. After the lithium battery is placed on the turnover device, however, when the lithium battery is transferred and moved, the lithium battery is extremely likely to shake along with the movement of the transfer device, and there is a risk of scratching the surface and dropping of the battery, which affects the transfer safety. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a lithium battery clamping and transferring device to solve the problems encountered in the above background art.

[0004] To achieve the above purpose, the technical solution of the utility model is as follows:

[0005] A lithium battery clamping and transferring device includes a moving base and a fixed baffle. Wheels are provided at the bottom of the moving base. The fixed baffle is installed on both sides of the moving base. A hollow frame is opened in the middle of the interior of the moving base, and a lead screw nut mechanism is installed in the hollow frame. The interior of the moving base is slidably connected with a transmission plate through a sliding groove. The transmission plate is in transmission connection with the lead screw nut mechanism. The top of the transmission plate extends out of the moving base and is fixedly connected with the fixed baffle. As a preferred solution, a layer of flexible contact layer is provided on the inner side of the fixed baffle.

[0006] Specifically, in the above solution, the lead screw nut mechanism includes a bidirectional lead screw and a transmission sleeve. The bidirectional lead screw is installed in the hollow frame. Limiting grooves are opened on both sides of the hollow frame. A servo motor for driving the bidirectional lead screw to rotate is provided outside the moving base. There are two transmission sleeves, which are sleeved on the upper and lower parts of the bidirectional lead screw respectively. The outer sides of each transmission sleeve are respectively in transmission connection with the transmission plate.

[0007] Furthermore, connecting rods are respectively provided on the outer sides of the transmission sleeve. A connecting frame is fixed on the inner side of the transmission plate. The connecting frame is hinged with the connecting rod through a push rod.

[0008] Still further, a guide tube is horizontally fixed on the outer side of the middle part of the hollow frame. A guide rod slidably connected with the guide tube is installed in the inner diameter of the guide tube. The end of the guide rod is fixedly connected with the inner side of the transmission plate.

[0009] In the above solution, the connecting rod moves up and down in the limiting groove under the rotational drive of the bidirectional lead screw; a first hinge seat is provided at the end of the connecting rod, the connecting frame includes a second hinge seat, and the second hinge seat is rotatably connected to the first hinge seat through a push rod.

[0010] In the above solution, the sliding groove is horizontally arranged, a raised block is provided at the top of the transmission plate, the width of the raised block is smaller than the width of the sliding groove, and the transmission plate is fixedly connected to the fixed baffle through the raised block.

[0011] In another embodiment, a lithium battery clamping and transporting device further includes a protective baffle, and the protective baffle is elastically connected to the outside of the fixed baffle.

[0012] Specifically, in the above solution, a hollow tube is fixed on the fixed baffle, a buffer spring is installed inside the hollow tube, a damping plate is installed at the outer end of the buffer spring, a movable rod 31 is fixed on the outer side of the damping plate, and the movable rod penetrates through the fixed baffle and its extended end is fixedly connected to the protective baffle.

[0013] In the above solution, a guiding block is provided at the feeding port of the moving base, and the guiding block is inclined downward.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: After the battery is placed in the transporting device, while performing a limiting and abutting process on the outer sides of the lithium battery placed on the surface of the moving base, the placed lithium battery can be pushed to be centered on the surface of the moving base, preventing it from being placed offset on the surface of the moving base, which may cause uneven stress on the overall placement of the moving base and affect the stability of the transporting and placing, thereby reducing the risk of lithium battery transportation.

[0015] Specifically:

[0016] 1. By movably sleeving the transmission sleeves on both outer sides of the bidirectional lead screw, when the servo motor operates to drive the bidirectional lead screw to rotate inside the hollow frame, the two groups of transmission sleeves can be driven to move synchronously inside the hollow frame in opposite or relative directions. Then, under the guiding and sliding action of the guiding tube on the guiding rod, the transmission plate and the fixed baffle located on the upper and lower sides of the moving base can move horizontally in opposite or relative directions synchronously, adjusting the distance between the fixed baffles so that they can perform a pushing and limiting process on the outer sides of the lithium battery placed on the surface of the moving base, and at the same time, the placed lithium battery can be pushed to be centered on the surface of the moving base, preventing it from being placed offset on the surface of the moving base, which may cause uneven stress on the overall placement of the moving base and affect the stability of the transporting and placing.

[0017] 2. The buffer spring and the damping plate are drivingly connected through the hollow tube and the movable rod. When the moving base and the lithium battery are being moved and transported, after the external impact force directly contacts the outside of the transmission plate, under the damping buffering effect of the buffer spring and the damping, the external impact force can be buffered to prevent the external impact force from directly acting on the surface of the lithium battery through the fixed baffle, further improving the quality of the transfer protection of the lithium battery.

[0018] 3. By adopting the above technical solution, the rationality of the transmission of the whole device is ensured by the guiding and sliding action of the hollow tube on the movable rod. The driving action of the servo motor can provide the power required for the rotation of the bidirectional lead screw. The buffer protection quality of the lithium battery can be improved by the structural action of the damping plate and the buffer spring. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present utility model, and should not be regarded as all of the present utility model or as a limitation or restriction on the technical solution of the present utility model.

[0026] The technical solution of the present utility model will be further described in detail below with reference to the drawings and embodiments.

[0027] Embodiment 1, as Figure 1 and Figure 2 shown, a lithium battery clamping and transporting device includes a moving base 1 and a fixed baffle 2. Wheels are provided at the bottom of the moving base 1, and the four wheels are installed at the bottom of the moving base 1 to facilitate the turnover and transportation of lithium batteries. The fixed baffle 2 is installed on both sides of the moving base 1 to clamp the lithium battery inside.

[0028] A hollow frame 21 is opened in the middle of the inside of the moving base 1. The hollow frame 21 is vertically arranged, and a lead screw nut mechanism is installed in the hollow frame 21. The inside of the moving base 1 is slidably connected with a transmission plate 25 through a horizontal sliding groove 42. The transmission plate 25 is in transmission connection with the lead screw nut mechanism, and the top of the transmission plate 25 extends out of the moving base 1 and is fixedly connected with the fixed baffle 2.

[0029] After the battery is placed in the transporting device, while performing a limiting and abutting process on the outer sides of the lithium battery placed on the surface of the moving base 1, the placed lithium battery can be pushed to place it in the middle of the surface of the moving base, avoiding the deviation of its placement on the surface of the moving base, which may cause uneven force on the overall placement of the moving base 1 and affect the stability of the turnover placement, and reducing the risk of lithium battery turnover.

[0030] As a preferred solution, in order to better protect the lithium battery, a flexible contact layer can be fixed on the inner side of the fixed baffle 2. The flexible contact layer can be made of items such as foam boards and towels that can be in flexible contact with the product, and is used to protect the lithium battery clamped by the two fixed baffles 2, reducing the probability of scratching the outer surface of the lithium battery during the turnover process.

[0031] A guide block 11 is provided at the feed inlet of the moving base 1, and the guide block 11 is inclined downward. The guide block 11 is integrally designed with the moving base 1 to facilitate receiving the lithium battery products conveyed by the production line. When the product is received, it can start to be turned to the storage station.

[0032] Embodiment 2, on the basis of Embodiment 1, please refer to Figure 2As shown in the figure, the lead screw nut mechanism includes a bidirectional lead screw 22 and a transmission sleeve 23. The bidirectional lead screw 22 is installed in a hollow frame 21. The hollow frame 21 is a rectangular frame structure. Limiting grooves 29 are provided on both sides of the hollow frame 21, and the limiting grooves 29 are longitudinally arranged on both sides. A servo motor 28 for driving the bidirectional lead screw 22 to rotate is provided on the outer side of the moving base 1. The servo motor 28 is installed at the top position of the hollow frame 21, and its output end is in transmission connection with the bidirectional lead screw 22. There are two transmission sleeves 23, which are sleeved on the upper and lower parts of the bidirectional lead screw 22 and are in threaded connection with the bidirectional lead screw 22. The outer sides of each transmission sleeve 23 are respectively in transmission connection with a transmission plate 25, so as to drive the transmission plate 25 to move closer to the middle or be pushed to both sides.

[0033] Furthermore, connecting rods 24 are respectively fixed on the outer sides of the transmission sleeves 23. The connecting rods 24 are located in the limiting grooves 29. A connecting frame 26 is fixed on the inner side of the transmission plate 25. The connecting frame 26 is hinged to the connecting rod 24 through a push rod. Driven by the rotation of the bidirectional lead screw 22, the connecting rod 24 moves up and down linearly in the limiting groove 29. Specifically, when implemented, a first hinge seat is provided at the end of the connecting rod 24. The connecting frame 26 includes a second hinge seat. The second hinge seat is rotationally connected to the first hinge seat through a push rod 27. Driven by the servo motor 28, the bidirectional lead screw 22 rotates to drive the transmission sleeve 23 to move up and down. Furthermore, under the pulling of the push rod 27, the transmission plate 25 is driven to move closer to the middle or be pushed to both sides.

[0034] It can also be arranged like this. Transmission plates 25 are slidably installed on the surfaces of both sides at the bottom of the moving base 1. Connecting frames 26 are fixedly installed on the surfaces of one end of each connecting rod 24 away from the transmission sleeve 23 and on the side of the transmission plate 25. Push rods 27 are hinged between the outer sides of every two groups of connecting frames 26 through a rotating shaft. Limiting grooves 29 are provided on both outer sides of the hollow frame 21, and the connecting rods 24 penetrate and are slidably inserted into the inside of the limiting grooves 29.

[0035] As a preferred solution, a guide tube 4 is horizontally fixed on the outer side of the middle part of the hollow frame 21. A guide rod 41 slidably connected to it is installed in the inner diameter of the guide tube 4. The end of the guide rod 41 is fixedly connected to the inner side of the transmission plate 25. The cooperation between the guide tube 4 and the guide rod 41 serves to guide the transmission plate 25. When implemented, a guide rod 41 is slidably installed through the middle part inside each guide tube 4, and the side of the guide rod 41 away from the hollow frame 21 is fixedly connected to the side of the transmission plate 25.

[0036] In the linkage movement between the fixed baffle 2 and the transmission plate 25, the sliding groove 42 is horizontally arranged. A raised block is provided on the top of the transmission plate 25, and the width of the raised block is smaller than the width of the sliding groove 42. Therefore, it can move linearly inside the sliding groove 42. The transmission plate 25 is fixedly connected to the fixed baffle 2 through the raised block. When the transmission plate 25 moves driven by the servo motor 28, the fixed baffle 2 will also move synchronously.

[0037] It can also be arranged in this way that fixed baffles 2 are slidably installed on both sides of the top of the moving base 1, and the bottom of the fixed baffle 2 is fixedly connected to the top of the transmission plate 25. Sliding grooves 42 are formed on both sides of the top of the moving base 1, and the rod-shaped protrusion on the top of the transmission plate 25 is slidably inserted into the sliding groove 42.

[0038] Embodiment 3, based on Embodiment 1 or 2, please refer to Figure 1 and Figure 3 As shown, a lithium battery clamping and transferring device includes a moving base 1 and a fixed baffle 2, and further includes a protective baffle 34. The protective baffle 34 is elastically connected to the outside of the fixed baffle 2. When it encounters other objects during the turnover process, it plays a buffering role to avoid harm to the internally clamped lithium battery.

[0039] A hollow tube 3 is fixed on the fixed baffle 2. The hollow tube 3 can be arranged on the inner surface that does not affect the clamping, and the flexible contact layer completely covers the outer circumference of the hollow tube 3, or it can be directly embedded and fixed in the plate body of the fixed baffle 2. A buffer spring 33 is installed inside the hollow tube 3. A damping plate 32 is installed at the outer end of the buffer spring 33. A movable rod 31 is fixed to the outer side of the damping plate 32. The movable rod 31 passes through the fixed baffle 2 and its extending end is fixedly connected to the protective baffle 34. The movable rod 31 plays a guiding role, and because it passes through the fixed baffle 2 and connects the protective baffle 34, the protective baffle 34 has a certain elastic buffering effect.

[0040] It can also be arranged in this way that hollow tubes 3 are fixedly installed on the surfaces of the four corners on the outside of each fixed baffle 2. A movable rod 31 is slidably inserted on the side of each hollow tube 3. A protective baffle 34 is fixedly installed between the sides of the movable rods 31, and the protective baffle 34 is movably located outside the fixed baffle 2. A damping plate 32 is fixedly installed on the surface of one side of each movable rod 31 away from the protective baffle 34, and the damping plate 32 is slidably installed inside the hollow tube 3. A buffer spring 33 is movably sleeved inside each hollow tube 3, and the side of the buffer spring 33 is movably attached to the outside of the damping plate 32.

[0041] In summary, when transporting lithium batteries in turnover, place the lithium batteries to be transferred and moved on the surface of the mobile base 1. Then, turn on the servo motor 28 through an external control switch, and its operation drives the bidirectional lead screw 22 to rotate. Under the guiding and driving action of the limiting groove 29 on the transmission sleeve 23 and the guiding and sliding action of the guiding tube 4 on the guiding rod 41, the two transmission sleeves 23 can horizontally move synchronously and relatively inside the hollow frame 21. Furthermore, under the transmission and conversion action of the push rod 27, the horizontal movement force of the transmission sleeve 23 can be converted into a pulling force on the transmission plate 25, enabling the transmission plate 25 to horizontally move towards each other at the bottom of the mobile base 1. Then, under the sliding action of the sliding groove 42 on the rod-shaped convex block at the top of the transmission plate 25, the fixed baffles 2 located on both sides of the top of the mobile base 1 can be driven to horizontally move towards each other until the fixed baffles 2 fit against the outside of the lithium battery and continuously push it, and then the lithium battery can be pushed to the middle position at the top of the mobile base 1. Subsequently, the fixed baffles 2 can perform a limiting and abutting process on both sides of the outside of the lithium battery.

[0042] During the transfer and movement of the lithium battery with the mobile base 1, when an external impact force contacts and impacts the surface of the protective baffle 34 from the side, while the protective baffle 34 moves towards the outside of the fixed baffle 2, with the buffering effect of the buffer spring 33 and the damping effect of the damping plate 32 on the reverse resonance force of the buffer spring 33, the external impact force is buffered to prevent the external impact force from directly acting on the outer wall of the lithium battery and causing damage, thereby improving the protection for the transfer of lithium batteries.
