DETAILED DESCRIPTION

[0028] The utility model will be made further detailed description in connection with the drawings and specific embodiment.

[0029] ATTACH Figures 1-2 The automatic disc loading equipment for the shell of battery cell comprises a belt conveying line 1 located at the discharge port of a stamping forming equipment, a speed chain conveying line 2 for conveying a material basket 7, a basket mounting frame 3 arranged between the belt conveying line 1 and the speed chain conveying line 2, an equidistant conveying belt 4 arranged on the basket mounting frame 3 and used for equidistantly conveying steel shells 8, an indexing feeding mechanism 5 arranged on the basket mounting frame 3 and used for grabbing the steel shells 8 from the belt conveying line 1 one by one and placing the steel shells 8 on the equidistant conveying belt 4, and a material swinging manipulator 6 arranged on the basket mounting frame 3 and used for grabbing four steel shells 8 from the equidistant conveying belt 4 at a time and placing the steel shells 8 in a material basket 7 on the speed chain conveying line 2.

[0030] When working, the steel shells 8 formed by stamping are automatically and vertically dropped on the belt conveying line 1, and the belt conveying line 1 automatically conveys the steel shells 8 to the indexing feeding mechanism 5; when the steel shells 8 reach the arranged position, the indexing feeding mechanism 5 grabs the steel shells 8 from the belt conveying line 1 one by one and places the steel shells 8 on the equidistant conveying belt 4, and then the equidistant conveying belt 4 automatically conveys the steel shells 8 to the material swinging manipulator 6 in an equidistant manner; when the four steel shells 8 reach the arranged position, the material swinging manipulator 6 grabs the four steel shells 8 from the equidistant conveying belt 4 at a time and places the steel shells 8 in the material basket 7 on the speed chain conveying line 2; when the material basket 7 is filled with the steel shells 8, the speed chain conveying line 2 directly sends the material basket 7 filled with the steel shells 8 to subsequent processing equipment for subsequent processing.

[0031] Why do we need to set up an equidistant conveyor belt 4 and a graduated loading mechanism 5, instead of directly using the swinging robot 6 to grab the steel shells 8 from the belt conveyor line 1 and place them in the material basket 7 on the double-speed chain conveyor line 2? The reason is: grabbing one by one is too slow. If you want to grab multiple steel shells 8 at a time, you need to place multiple steel shells 8 at equal distances, but the belt conveyor line 1 cannot achieve this. In addition, if you set up an equidistant conveyor belt 4, you can also install a laser coding machine to facilitate recording information such as the production equipment and production time of the steel shells 8, which is convenient for later traceability.

[0032] Further, if Figure 3 As shown, the indexing feeding mechanism 5 includes a mounting base 51, a guide bracket 52 vertically arranged on the mounting base 51, a lifting frame 53 slidably arranged in the guide bracket 52, a lifting driver 54 vertically arranged on the basket loading frame 3 for driving the lifting frame 53 to move up and down, a dividing plate 55 horizontally and rotatably arranged on the top of the lifting frame 53, a rotary driver 56 arranged in the lifting frame 53 for driving the dividing plate 55 to rotate intermittently, and at least two clamping jaw assemblies 57 arranged at the edge of the dividing plate 55 and placed rotationally symmetrically; each of the clamping jaw assemblies 57 includes a support arm 571 extending radially along the dividing plate 55 and a clamping jaw cylinder 572 horizontally arranged at the end of the support arm 571;

[0033] Each time the belt conveyor line 1 transports the steel shell 8 to the set position, there is a group of clamping jaw assemblies 57 located above the steel shell 8. At this time, the lifting driver 54 drives the lifting frame 53 to descend until the steel shell 8 is located in the clamping jaws of the clamping jaw cylinder 572, and the steel shell 8 is clamped by the clamping jaw cylinder 572. Then the lifting driver 54 drives the lifting frame 53 to rise back to the initial position, and then the rotary driver 56 drives the dividing plate 55 to rotate 90 degrees, and then the lifting driver 54 drives the lifting frame 53 to descend again until the steel shell 8 grasped by the previous group of clamping jaw assemblies 57 falls on the equidistant conveyor belt 4, and then the clamping jaw cylinder 572 releases the steel shell 8. Finally, the lifting driver 54 drives the lifting frame 53 to rise back to the initial position again, and the cycle is repeated in sequence. The equidistant conveyor belt 4 automatically transports multiple steel shells 8 equidistantly toward the swinging robot 6.

[0034] Further, if Figure 3 As shown, each of the clamping jaw assemblies 57 is further provided with a rotating cylinder 573 between the support arm 571 and the clamping jaw cylinder 572, which is used to drive the clamping jaw assembly 57 to drive the steel shell 8 to vertically flip 180 degrees to meet specific processing needs.

[0035] Furthermore, the lifting drive 54 can be an electric cylinder or a pneumatic cylinder, which can be selected as needed.

[0036] Furthermore, the rotary driver 56 may be an intermittent divider or a reduction motor, which may be selected as needed.

[0037] Further, ifFigure 3 As shown, the two sides of the lifting frame 53 and the guide bracket 52 are provided with vertical guide rails, which play a guiding role.

[0038] Further, as shown in the figure, Figure 4 As shown, the equidistant conveying belt 4 is provided with a ring of equidistant positioning seats 41; during operation: the indexing feeding mechanism 5 picks up the steel shells 8 from the belt conveying line 1 one by one and places them on the positioning seats 41; the positioning seats 41 not only play a positioning role on the steel shells 8, but also prevent the steel shells 8 from tilting during conveying.

[0039] Further, as shown in the figure, Figure 2 and Figure 5 As shown, the material swinging manipulator 6 includes a four-axis mechanical arm 61 and a material taking assembly 62 provided at the driving end of the four-axis mechanical arm 61; the material taking assembly 62 includes a variable-distance module 621 and a plurality of pneumatic clamps 622 vertically provided at the driving end of the variable-distance module 621.

[0040] During operation: the four-axis mechanical arm 61 drives the four pneumatic clamps 622 to pick up four steel shells 8 from the equidistant conveying belt 4 at a time and place them in the feeding basket 7 of the multiple-speed chain conveying line 2; since the diameters of different models of steel shells 8 are different, the center distances of different models of steel shells 8 in the feeding basket 7 are also different, so the variable-distance module 621 is added to automatically adjust the center distance of the four steel shells 8 after picking them up, so that they can be installed and placed in the feeding basket 7 as required.

[0041] Further, as shown in the figure, Figure 5 Since the pneumatic clamps 622 are vertically placed and pick up the top of the steel shells 8, the pneumatic clamps 622 adopt a four-claw structure, which is more stable when clamping the top of the steel shells 8.

[0042] Further, as shown in the figure, Figure 5 As shown, the pneumatic clamps 622 are provided with an infrared sensor 623 for sensing whether there is a steel shell 8 in the pneumatic clamps 622 to avoid empty operation.

[0043] Further, as shown in the figure, Figure 6 As shown, the variable-distance module 621 is provided with a floating assembly between the driving end and the pneumatic clamps 622; the floating assembly includes a fixed plate 624 vertically provided at the driving end of the variable-distance module 621, a sliding rail 625 vertically provided on the fixed plate 624, and a floating plate 626 slidingly provided on the sliding rail 625; the top end of the floating plate 626 is connected to the driving end of the variable-distance module 621 through a spring 627; the pneumatic clamps 622 are installed on the lower end side of the floating plate 626; the fixed plate 624 is provided with a photoelectric groove switch 628; and the floating plate 626 is provided with an induction sheet 629 that can trigger the photoelectric groove switch 628.

[0044] In normal operation, the floating plate 626 is in a suspended state under its own weight, and the inductive sheet 629 does not trigger the photoelectric trough switch 628; when the material placing manipulator 6 drives the pneumatic gripper 622 to grab the steel shell 8 downward, if the pneumatic gripper 622 is blocked by foreign matter (for example, the position of the steel shell 8 has deviated, and the gripper is pressed against the top end of the steel shell 8), the spring 627 will overcome the elastic force and push the floating plate 626 upward, so that the inductive sheet 629 triggers the photoelectric trough switch 628, so that the material placing manipulator 6 stops driving the pneumatic gripper 622 to move downward, avoiding damage to the pneumatic gripper 622, and the spring 627 also functions as a buffer.

[0045] Further, as shown in Figure 7 , a guide frame 11 is arranged above the feeding end of the belt conveying line 1; the guide frame 11 is provided with guide holes 12, which can enable the steel shell 8 punched and formed on the punching and forming equipment to accurately fall on the belt conveying line 1.

[0046] Further, as shown in Figure 8 , a support seat 13 is arranged on one side of the belt conveying line 1 close to the discharging end; the support seat 13 is provided with two groups of blocking mechanisms 14 arranged in parallel; each group of blocking mechanisms 14 comprises a guide rail 141 arranged on the support seat 13 and arranged vertically to the belt conveying line 1, a blocking piece 142 slidingly arranged on the guide rail 141, and a blocking cylinder 143 arranged on the support seat 13 and used to drive the blocking piece 142 to extend into the belt conveying line 1 to block the steel shell 8; the spacing between the blocking pieces 142 of the two groups of blocking mechanisms 14 can only accommodate one steel shell 8.

[0047] When the belt conveying line 1 conveys the steel shell 8 to the discharging end, if there is a steel shell 8 at the discharging end, the blocking mechanism 14 will extend into the belt conveying line 1 to block the steel shell 8; after the indexing feeding mechanism 5 grabs the steel shell 8 from the discharging end of the belt conveying line 1 and places it on the positioning seat 41, the two groups of blocking mechanisms 14 cooperate to ensure that only one steel shell 8 is placed at the discharging end of the belt conveying line 1 each time to wait for the indexing feeding mechanism 5 to grab it.

[0048] Further, as shown in Figure 7 , the bottom of the belt conveying line 1 is provided with a cleaning mechanism 15 for cleaning the surface of the belt; since the belt conveying line 1 is directly connected to the discharge port of the punching and forming equipment, the steel shell 8 may also fall on the belt conveying line 1 with metal waste, and if the metal waste adhering to the belt conveying line 1 is not cleaned, the surface of the belt may become uneven after a long time, causing the steel shell 8 to be tilted or the like.

[0049] Further, as shown in Figure 8 , the cleaning mechanism 15 comprises a brush assembly 151 and a roller brush assembly 152 arranged in the conveying direction of the belt conveying line 1; in this embodiment, the brush assembly 151 is provided with two groups;

[0050] The brush assembly 151 comprises a first receiving box 1511 arranged at the bottom of the belt conveying line 1, and a brush 1512 fixedly arranged in the first receiving box 1511 and in contact with the belt surface at the bottom of the belt conveying line 1;

[0051] The brush assembly 151 comprises a first receiving box 1511 arranged at the bottom of the belt conveying line 1, and a brush 1512 fixedly arranged in the first receiving box 1511 and in contact with the belt surface at the bottom of the belt conveying line 1;

[0052] When the belt conveying line 1 circulates the steel shell 8, the brush 1512 first preliminarily cleans the belt surface, and the metal waste cleaned falls into the first receiving box 1511 automatically; then the roller brush 1522 is driven to rotate by the motor 1523, so as to further remove the stubborn metal waste remaining on the belt surface, and the metal waste cleaned also falls into the second receiving box 1521 automatically.

[0053] Further, the speed-increasing chain conveying line 2 adopts a double-layer structure, one end of which is arranged with a lifting transplanter, and the conveying directions of the upper and lower conveying lines are opposite, the upper conveying line is used for conveying the basket 7 storing the steel shell 8, and the lower conveying line is used for conveying the empty basket 7, so that the circulation of the basket 7 can be realized under the cooperation of the lifting transplanter, and the degree of automation is high.

[0054] The above is only a specific application example of the present application, and does not constitute any limitation on the protection scope of the present application. Any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the present application.
