Description

Technical Field

[0001] The utility model relates to the technical field of battery sheet processing, and specifically to an automatic feeding mechanism for lithium battery processing. Background Art

[0002] The existing equipment loads lithium batteries by placing battery cells on a loading platform. Through the operation of the limit assembly, the two sets of baffles can be driven to move in relative or opposite directions until the battery cells on the loading platform contact the inner side of the baffles. The L-shaped plate can then be driven to move through the operation of the electric push rod. Since the bottom of the loading platform is slidably connected to the fixed rod through a sliding sleeve, the operation of the electric push rod can drive the loading platform to move to one side of the feed port. After the loading platform is aligned with the feed port, the electric telescopic rod works again, thereby driving the scraper plate at the bottom to move. The scraper plate pushes the battery cells on the loading platform into the feed port, thereby realizing automatic loading of battery cell processing.

[0003] The above equipment requires the staff to place the battery cells on the loading platform, and the scraper plate can push the battery cells on the loading platform into the feeding port to realize loading. This automatic loading method of one piece after another consumes a lot of manpower and time, resulting in low production efficiency and long production cycle, which cannot meet the needs of large-scale production. Therefore, an automatic loading mechanism for lithium battery processing is needed. Utility Model Content

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Lithium battery is a type of battery that uses lithium compounds as charge carriers between the positive and negative electrodes. Lithium batteries have the characteristics of high energy density, light weight, and long cycle life, and are widely used in many fields, such as portable electronic devices, electric vehicles, energy storage systems, etc. Lithium batteries are generally composed of a positive electrode, a negative electrode, an electrolyte, and a separator. During the charging process, lithium ions are released from the positive electrode and move to the negative electrode through the electrolyte. An automatic loading mechanism for lithium battery processing is a device that can automatically transfer battery cells from a storage area or a supply area to a processing device.

[0024] The existing equipment requires the staff to put the battery cells on the loading platform, and the scraper can push the battery cells on the loading platform into the feeding port to load the cells. This automatic loading method of one cell after another consumes a lot of manpower and time, resulting in low production efficiency and long production cycle, and cannot meet the needs of large-scale production. Figure 1-Figure 4 The embodiment provides an automatic feeding mechanism for lithium battery processing, including a processing equipment body 1 and a feeding port 11 opened on the side wall of the processing equipment body 1, two mounting plates 2 are fixedly connected to the side of the processing equipment body 1, and a stacking box 4 is arranged on the top of one of the mounting plates 2. A plurality of battery cells are stacked in sequence from top to bottom in the stacking box 4, and the plurality of battery cells enter the feeding port 11 in sequence through the feeding assembly 8 and are then put into the processing equipment body 1.

[0025] As shown in reference 4, a support plate 41 fixedly connected to the top of one of the mounting plates 2 is fixedly connected to the side of the stacking box 4 away from the processing equipment body 1, and the setting of the support plate 41 plays the role of setting up the stacking box 4. A push groove 42 is opened at the bottom of the stacking box 4, and the bottommost battery cell in the stacking box 4 falls into the limit slot 71. When the push rod 84 and the limit rod 85 move to the left, the push rod 84 can push the battery cell to move to the right through the opening of the circulation slot 42.

[0026] refer to Figure 3 As shown, a slide 7 is provided at the bottom end of the stacking box 4, and a limit slot 71 is provided at the top of the slide 7. The limit slot 71 is adapted to the size of the battery cell and is used to limit the battery cell during transportation. The bottom end of the stacking box 4 is opposite to the top of the slide 7 away from the feed port 11, and the inner cavity size of the stacking box 4 is the same as the inner cavity size of the limit slot 71. The battery cells in the stacking box 4 are placed into the limit slot 71 one by one as they are pushed. The inner size of the limit slot 71 is adapted to the size of the battery cell, so that a limit is formed during the transportation of the battery cell to prevent the battery cell from slipping.

[0027] refer to Figure 3-Figure 4As shown, the staff puts the battery cells onto the loading platform, and the scraper plate can push the battery cells on the loading platform into the feed port to realize loading. This automatic loading method of one piece after another consumes a lot of manpower and time, resulting in low production efficiency and long production cycle, which cannot meet the needs of large-scale production. In order to reduce the intermittent time of loading and thus meet the needs of large-scale production, the following settings are made: a loading assembly 8 for pushing the battery cells to continuously enter the feed port 11 is provided at the bottom of the slide 7, and the loading assembly 8 includes a sliding plate 81 sliding at the bottom of the slide 7, and the two sides of the sliding plate 81 are symmetrically fixedly connected with There are four sliders, and two sliders are symmetrically opened on both sides of the slide 7. The four sliders slide horizontally along the inner tracks of the two slides respectively. The top of the sliding plate 81 is fixedly connected to the mounting recessed plate 82, and the inner rotation of the mounting recessed plate 82 is connected to the torsion bar 83. The outer wall of the middle end of the torsion bar 83 is fixedly connected to the push rod 84, and one side of the bottom end of the push rod 84 is fixedly connected to the limit rod 85. The length of the push rod 84 is greater than the length of the limit rod 85, and the push rod 84 and the limit rod 85 are set at an obtuse angle. The outer walls of both ends of the torsion bar 83 are sleeved with torsion springs 86, and the elastic force of the torsion springs 86 cannot push the battery cell body. The two ends of the torsion spring 86 are fixedly connected to the mounting recessed plate 82 and the torsion bar 83 respectively, and the sliding plate 81 slides leftward so that the pushing rod 84 pushes the battery cell on the right side of the battery cell to move toward the feeding port 11. When the pushing rod 84 pushes the battery cell to move leftward, the limiting rod 85 is away from one end of the pushing rod 84 and abuts against the top of the sliding plate 81. When the sliding plate 81 slides rightward, the limiting rod 85 is away from one end of the pushing rod 84 and cannot abut against the top of the sliding plate 81, so that the pushing rod 84 cannot push the battery cell, causing the pushing rod 84 and the limiting rod 85 to rotate leftward through the torsion bar 83. Since the length of the pushing rod 84 is greater than the length of the limiting rod 85, and the pushing rod 84 and the limiting rod 85 are set at an obtuse angle, the limiting rod 85 after rotating leftward cannot contact the bottom of the battery cell, thereby causing the pushing rod 84 and the limiting rod 85 to smoothly pass through the bottom of the battery cell to the right side of the battery cell. The pushing rod 84 and the limiting rod 85 that have arrived at the right side of the battery cell are reset by the torsion spring 86 to carry out a new round of battery cell pushing and loading.

[0028] refer to Figure 2 As shown, a driving assembly 6 is provided on the side of the sliding plate 81 away from the processing equipment body 1 and close to the stockpile box 4. The driving assembly 6 includes a cylinder 61 fixed on the top of one of the mounting plates 2. The telescopic end of the cylinder 61 is fixedly connected with a linkage plate 62. The side of the linkage plate 62 away from the cylinder 61 is fixedly connected with a driving rod 63. The sliding plate 81 is fixed to the end of the driving rod 63 away from the cylinder 61. Starting the cylinder 61 causes the telescopic end to drive the linkage plate 62 to move back and forth. The displacement of the linkage plate 62 drives the driving rod 63 to push the sliding plate 81 to enable the loading assembly 8 to operate normally.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
