Description

Technical field:

[0001] This utility model relates to the field of lithium battery processing technology, and more specifically to a lithium battery cell conveying and cleaning device. Background technology:

[0002] In the current lithium battery manufacturing process, the battery cells are installed into the lithium battery casing. During processing, the lithium battery cells need to be removed from the packaging box and placed in cleaning equipment to clean their two large side walls (the other side walls are smaller and have little to no dirt, so they do not need cleaning). The current cleaning method involves using the nozzle of a plasma cleaning machine to spray the large side walls of the battery cells to remove dirt. However, the current plasma cleaning method can only clean one large side wall of the battery cell, and then the battery cell needs to be rotated 180 degrees to clean the other large side wall; this process is inefficient. Utility Model Content:

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a lithium battery cell conveying and cleaning device that can simultaneously clean the large-area walls on both sides of the battery cell as it is conveyed by the conveyor belt, resulting in good cleaning effect and high efficiency.

[0004] The solution of this utility model to the aforementioned technical problem is:

[0005] A lithium battery cell conveying and cleaning device includes a main support frame. The top surface of the left and right side beams of the main support frame is fixed with a horizontally extending fixing plate. A left and right moving mechanism is installed on the horizontally fixed plate, and a plasma cleaning host is fixed on the moving block of the left and right moving mechanism.

[0006] The front and rear side beams of the main support frame are fixed with a conveyor frame that extends forward and backward.

[0007] The plasma nozzles of the two plasma cleaning units are facing the left and right walls of the battery cells being transported on the conveyor belt.

[0008] The conveyor frame includes two side support plates, the bottom surfaces of which are fixed to the top surfaces of the front and rear side beams of the main support frame. Two drive rollers are located between the front and rear of the two side support plates. The two ends of the drive rollers are movably connected to the two side support plates through bearings. A conveyor motor is fixed on the outer wall of one of the side support plates. The conveyor motor drives the corresponding drive roller to rotate, and the conveyor belt is tensioned on the two drive rollers.

[0009] The two side support plates are formed with side through grooves facing the plasma nozzle.

[0010] The left and right moving mechanism includes a fixed plate fixed in the middle of the horizontal fixed plate and the top surface of the inner end. The two ends of the left and right extending adjusting screw are movably connected to the two fixed plates through bearings. An external moving motor is fixed on the outer side of the outer fixed plate. The external moving motor drives the adjusting screw to rotate. The moving block is screwed onto the adjusting screw.

[0011] Multiple guide rods are provided between the two fixed plates. The two ends of the guide rods are fixed to the two fixed plates, and the guide rods are inserted into the corresponding guide through holes on the moving block.

[0012] The outstanding effects of the utility model are:

[0013] Compared with existing technologies, it can simultaneously clean the large-area walls on both sides of the battery cell as it is conveyed by the conveyor belt, resulting in better cleaning effect and higher efficiency. Attached image description:

[0017] Figure 4 This is a partial structural diagram of the upper support frame and the conveyor frame. Detailed implementation method:

[0018] For example, see Figures 1 to 4 As shown, a lithium battery cell conveying and cleaning device includes a main support frame 10. The top surface of the left and right side beams of the main support frame 10 is fixed with a horizontally extending fixing plate 11. A left and right moving mechanism 20 is installed on the horizontally fixed plate 11. A plasma cleaning host 40 is fixed on the moving block 21 of the left and right moving mechanism 20.

[0019] The front and rear two side beams of the main support frame 10 are fixed with a conveyor frame 30 extending forward and backward. The plasma nozzles 41 of the two plasma cleaning hosts 40 face the left and right side walls of the battery cells 100 conveyed on the conveyor belt 31. The two side support plates 32 of the conveyor frame 30 are formed with side through grooves 321 facing the plasma nozzles 41.

[0020] Furthermore, the conveyor frame 30 includes two side support plates 32, the bottom surfaces of which are fixed to the top surfaces of the front and rear side beams of the main support frame 10. Two transmission rollers 12 are located between the front and rear parts of the two side support plates 32. The two ends of the transmission rollers 12 are movably connected to the two side support plates 32 through bearings. A conveyor motor 33 is fixed on the outer wall of one of the side support plates 32. The output shaft of the conveyor motor 33 is a spline shaft, which is inserted into the spline hole at one end of the corresponding transmission roller 12 and drives the corresponding transmission roller 12 to rotate. The conveyor belt 31 is tensioned on the two transmission rollers 12.

[0021] Furthermore, a support plate 34 extending forward and backward is fixed between the middle of the two side support plates 32. The left and right side walls of the support plate 34 are fixed to the inner side walls of the two side support plates 32. Multiple compression springs 35 are installed on the top surface of the support plate 34. An upper horizontal support plate 36 is fixed to the top surface of all the compression springs 35, and the top surface of the upper horizontal support plate 36 presses against the bottom surface of the upper belt of the conveyor belt 31. The compression springs 35 ensure that the top surface of the upper horizontal support plate 36 presses against the upper belt of the conveyor belt 31, making the upper belt taut, which can protect the battery cells conveyed on the upper belt of the conveyor belt 31.

[0022] Furthermore, the top surface of the support plate 34 is fixed with a plurality of positioning sleeves 341, and the bottom surface of the upper horizontal support plate 36 is fixed with a plurality of upper positioning posts 361. The upper positioning posts 361 are inserted into the corresponding positioning sleeves 341, and the compression springs 35 are inserted into the corresponding positioning sleeves 341 and upper positioning posts 361. The bottom surface of the compression springs 35 presses against the top surface of the support plate 34.

[0023] Furthermore, the left and right moving mechanism 20 includes a fixed plate 22 fixed to the middle and inner top surface of the transverse fixed plate 11. The two ends of the left and right extending adjusting screws 23 are movably connected to the two fixed plates 22 through bearings. An external moving motor 24 is fixed on the outer side of the outer fixed plate 22. The output shaft of the external moving motor 24 is a splined shaft, which is inserted into the splined hole at one end of the corresponding adjusting screw 23 and drives the adjusting screw 23 to rotate. The moving block 21 is screwed onto the adjusting screw 23.

[0024] Furthermore, a plurality of guide rods 25 are provided between the two fixed plates 22. The two ends of the guide rods 25 are fixed on the two fixed plates 22, and the guide rods 25 are inserted into the corresponding guide through holes on the moving block 21.

[0025] Furthermore, an upper support frame 60 is fixed to the top surface of the middle part of the side beam at the rear of the main support frame 10. The conveyor frame 30 is inserted into the upper support frame 60. At least one through hole is formed in the middle of the top plate of the upper support frame 60. The suction connection pipe 61 is inserted into the corresponding through hole. The outer side wall of the suction connection pipe 61 is pressed against the inner side wall of the through hole. The bottom end of the suction connection pipe 61 faces the conveyor belt 31 of the conveyor frame 30 below.

[0026] The upper part of the suction connection pipe 61 can be connected to an external suction and dust removal device through the connection pipe to achieve suction.

[0027] In this embodiment, the battery cell 100 to be cleaned is placed above the rear of the upper part of the conveyor belt 31. As the conveyor belt 31 runs (at this time, the left and right side walls of the battery cell 100 are large-area side walls), the battery cell 100 is conveyed forward. When it passes the bottom of the two suction connection pipes 61, the suction connection pipes 61 suck in air, which can adsorb some dust and other particles on the outer side wall of the battery cell 100.

[0028] Then, the conveying continues, and when it passes between the two side passages 321, the large-area sidewalls of the battery cell 100 are cleaned by plasma spraying through the plasma nozzles 41 on both sides.

[0029] Then, it continues to be conveyed forward with the conveyor belt 31. During the conveying process, there is a certain distance between two adjacent battery cells 100, generally a gap of 20cm to 30cm, to prevent the battery cell 100 behind from hitting the battery cell 100 in front when the battery cell 100 in front is not grabbed.

[0030] An infrared transmitter 1 and an infrared receiver 2 are respectively fixed on the top surface of the left side of the two side support plates 32 of the conveyor frame 30. The infrared transmitter 1 irradiates infrared rays onto the receiving end of the infrared receiver 2. The infrared transmitter 1 and the infrared receiver 2 are electrically connected to the control host through an electrical connection line. All electrical equipment and components in this embodiment are electrically connected to the control host through an electrical connection line and are controlled by the control host. This is a conventional structure and will not be described in detail here.

[0031] Until the front of the battery cell 100 blocks the infrared radiation from the infrared transmitter 1 and shines on the infrared receiver 2, the infrared receiver 2 sends a sensing signal to the control host. The control host then controls the subsequent gripping mechanism connected to it to grip the battery cell 100, remove it from the conveyor belt 31, and then move it to the installation position or conveying position of the subsequent equipment.

[0032] In this embodiment, the conveyor belt 31 moves at a relatively slow speed. Therefore, it does not need to stop during the gripping process of the gripping mechanism, allowing the battery cell 100 to be gripped and removed during normal transport.

[0033] This embodiment can simultaneously perform plasma cleaning on both the left and right side walls of the battery cell 100, which is highly efficient and effective.

[0034] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
