Description

Technical Field

[0001] The invention belongs to the technical field of sorting devices, and in particular relates to a plate sorting system for lead-acid battery production. Background Art

[0002] Lead-acid batteries are widely used because of their high operating voltage, wide operating temperature, good high and low rate discharge performance, easy-to-obtain raw materials and low price. As the main component of lead-acid batteries, the plate stores electrical energy when the battery is charged and releases electrical energy when the battery is discharged. It can be cycled repeatedly, thus constituting the charge and discharge function of lead-acid batteries. At present, the main plate manufacturing methods in the industry include single-piece plate coating, continuous plate coating and tubular lead paste injection. In the production process of batteries, due to manufacturing errors and other reasons, the electrode plates of the produced batteries often have different weights. Therefore, a very important process in the production process of batteries is to weigh and sort the plates, and then assemble the batteries with different weight combinations of plates.

[0003] For example, CN100509184C discloses a method for rapid parallel weighing and sorting of battery plates, in which each workstation is sequentially arranged into a weighing and sorting circle; in this technical solution, it is not possible to weigh multiple plates at the same time, which results in low actual weighing and sorting during use.

[0009] Furthermore, the distance between any two adjacent guide rail structures is L0, and the camera is tilted toward the direction of the plate material on the first conveyor line; and the viewing angle width of any camera on the first conveyor line is L1, and L1≤L0; the fields of view of several cameras on the first conveyor line do not overlap.

[0010] Furthermore, when any of the cameras takes a photo of the first conveyor line and obtains a photo, the photo is analyzed to obtain a plate in the photo, the distance between the plate and the corresponding camera is determined, and then the displacement control mechanism is controlled to grab the plate conveyed on the first conveyor line after a delay of t time according to the conveying speed of the first conveyor line.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0027] like Figure 1 The present invention provides a plate sorting system for lead-acid battery production, comprising a first conveyor line 1 and three second conveyor lines 2 arranged on both sides of the end of the first conveyor line 1, and five groups of displacement control mechanisms are arranged at equal intervals along the conveying direction of the first conveyor line 1, and a group of weighing structures 10 are respectively arranged on both sides of the first conveyor line 1 directly below any displacement control mechanism; then based on the above arrangement, when in use, the first conveyor line 1 is arranged at the end of a continuous plate rolling and cutting device, at which time the plates 100 produced by the continuous plate rolling and cutting device are divided into two columns and conveyed on both sides of the first conveyor line 1, and then when in use, the plates 100 on the first conveyor line 1 are grabbed by the displacement control mechanism and placed on the weighing structure 10 for weighing, and after the weighing is completed, the displacement control mechanism is controlled to grab the plates 100 and place them on the corresponding second conveyor line 2 according to the weighing result.

[0028] In the above, in order to facilitate the use of the displacement control mechanism to grab the electrode plate 100 and control the movement of the electrode plate 100 in the horizontal and vertical directions, the provided displacement control mechanism includes a guide rail structure 3 whose length direction is perpendicular to the conveying direction of the first conveyor line 1, and the guide rail structure 3 is equipped with two electric sliders 31 that slide along its length direction. The ends of the electric sliders 31 are installed with telescopic cylinders 32 in the vertical direction, and the ends of the telescopic cylinders 32 are connected to the grabbing module 33 for grabbing the electrode plate 100. When in use, the telescopic cylinder 32 is controlled to extend until the grabbing module 33 contacts the electrode plate 100 to grab the electrode plate 100. After grabbing, the telescopic cylinder 32 is controlled to retract until the bottom side of the electrode plate 100 is higher than the working surfaces of the first conveyor line 1, the second conveyor line 2 and the weighing structure 10, and then the electric slider 31 is controlled to move along the length direction of the guide rail structure 3.

[0029] Specifically, in order to better coordinate the five groups of displacement control mechanisms to grasp the pole plate 100, in a possible technical solution, a camera is installed on the guide structure 3 between the two electric sliders 31. The camera is used to take pictures of the pole plate conveying information on the first conveying line 1 to obtain pictures, and at the same time, the pictures obtained by taking pictures are transmitted to the processor, and the processor analyzes the pictures.

[0030] What we know is that Figure 3 As shown, based on the setting of the above-mentioned cameras, when the equipment is assembled, the present invention controls the distance between any two adjacent guide rail structures 3 to be 70 cm, and the viewing angle width of any camera installed on the guide rail structure 3 on the first conveyor line 1 is 60 cm, and the camera is tilted toward the direction of the electrode 100 on the first conveyor line 1; and the fields of view of several cameras on the first conveyor line 1 do not overlap.

[0031] It can be understood that, based on the setting of the camera, when any camera takes a photo of the first conveyor line 1 and obtains a photo, the photo obtained is transmitted to the processor, and the processor analyzes the photo and obtains that there is a plate 100 in the photo, and simultaneously determines the distance between the plate 100 and the corresponding camera, and then controls the displacement control mechanism to grab the plate 100 conveyed on the first conveyor line 1 after a delay of t time according to the conveying speed of the first conveyor line 1.

[0032] Specifically, distance sensors for detecting the position of the electric slider 31 on the guide rail structure 3 are respectively arranged at both ends of the guide rail structure 3, and the position of the electric slider 31 on the guide rail structure 3 is detected by the distance sensor, thereby controlling the displacement control mechanism to grab the pole plate 100 and place it on the corresponding second conveyor line 2.

[0033] When using, Figure 4In order to facilitate the use of the weighing structure 10 to weigh the electrode plate 100, the weighing structure 10 provided by the present invention includes a bottom plate 101 and a weighing platform body 102 arranged on the upper surface of the bottom plate 101; a plurality of damping telescopic structures 103 are arranged on the upper surface of the bottom plate 101 located on the peripheral side of the weighing platform body 102, and the ends of the damping telescopic structures 103 are connected to the support frame 104, and a lifting cylinder 105 is arranged between the two damping telescopic structures 103 located on the same side of the weighing platform body 102, and the ends of the lifting cylinders 105 are against the bottom side of the support frame 104. When in use, the displacement control mechanism is used to grab the electrode plate 100 and place it on the support frame 104, and then the lifting cylinder 105 is controlled to shrink. At this time, under the action of the gravity of the electrode plate 100 and the support frame 104, the damping telescopic structure 103 is driven to slowly shrink until the bottom side of the electrode plate 100 contacts the weighing platform body 102 to complete the weighing.

[0034] Specifically, Figure 4 The output end of the damping telescopic structure 103 is connected to a movable sleeve 107 that is movably sleeved along the output end through a spring, and a flange 1071 is provided at the end of the movable sleeve 107; the end of the lifting cylinder 105 is connected to a connecting rod 106, and both ends of the connecting rod 106 are provided with a sleeve ring 1061 sleeved on the movable sleeve 107, and the inner diameter of the sleeve ring 1061 is smaller than the outer diameter of the flange 1071 and larger than the outer diameter of the movable sleeve 107; and when in use, after the lifting cylinder 105 is controlled to shrink to the first state, the damping telescopic structure 103 is controlled to be between the plate 100 and the support frame. 104 slowly descends under the action of gravity until the bottom side of the electrode plate 100 contacts the weighing platform body 102; then, to avoid the problem that the gravity of the support frame 104 cannot control the damping telescopic structure 103 to continue to move downward, thereby causing the support frame 104 to contact the electrode plate 100, thereby causing an error in weighing the electrode plate 100, the lifting cylinder 105 is controlled to continue to shrink during use. At this time, the flange 1071 and the ring 1061 are used to cooperate to control the damping telescopic structure 103 to continue to shrink. At this time, the support frame 104 is controlled to detach from the bottom side of the electrode plate 100.

[0035] Specifically, Figure 5The damping telescopic structure 103 includes a sleeve rod 1031 and a sleeve 1030 which are sleeved with each other, and a reset spring 1036 is connected between the sleeve rod 1031 and the sleeve 1030. The inner bottom side surface of the sleeve 1030 is connected with a damping column 1033 through a connecting rod 1032. The bottom side surface of the sleeve rod 1031 is recessed upward to form a damping cavity 1034 that cooperates with the damping column 1033. The damping column 1033 is provided with a through hole 1035 along its axial direction. The diameter of the through hole 1035 is less than 0.5 mm. The setting of the through hole 1035 ensures that when the damping telescopic structure 103 contracts, the gas in the damping cavity 1034 is slowly delivered into the sleeve 1030 through the through hole 1035, thereby keeping the damping telescopic structure 103 contracting slowly.
