[0063] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0064] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0065] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features.

In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0066] See Figure 1 In practice, valve-regulated sealed lead-acid batteries (hereinafter referred to as batteries) must be boxed and loaded with accessories before shipment. Due to their weight, batteries are typically placed on pallets. The specific boxing process is as follows: 1. The battery is manually flipped so that the bottom of the battery faces upward, creating an upside-down position; 2. A layer of protective foam is placed on the front of the battery due to its inherent weight; 3. The battery is placed in a cardboard box and both the battery and the box are turned upright; 4. The battery accessories are placed on the front of the battery and the box is sealed.

[0067] During the process of flipping the battery from upright to inverted, the weight of the battery itself can easily damage the protective foam on the front. Furthermore, the battery undergoes two manual flips, and the speed and force of each flip cannot be controlled to be consistent, effectively cushioning the battery within the carton. This can cause unexpected collisions and damage to the battery. This results in low production efficiency during the boxing process and easily damages the batteries and packaging materials.

[0068] See Figure 2-3In an embodiment of the present invention, a lead-acid battery box loading and sealing linkage system is proposed, comprising: a conveyor chain 1, a turning device 2, and a box sealing device 3; the turning device 2 is located at one end of the conveyor chain 1; the box sealing device 3 is located on one side of the turning device 2; the upside-down batteries 4 and cartons 5 are transported to the turning device 2 via the conveyor chain 1; the turning device 2 is provided with a tray 21, a turning motor 22, and a gripper 23; the output end of the turning motor 22 is connected to the gripper 23; the gripper 23 is located directly above the tray 21.

[0069] The lead-acid battery boxing and sealing linkage system of the present invention is used as follows: after the screen printing is completed, the battery 4 comes out of the oven and is placed on the conveyor chain 1 at a 90° side position. After placing protective foam on the front of the battery 4, the battery 4 is flipped 90° to an inverted position. The battery 4 is then buckled onto the carton 5 and conveyed to the flipping device 2 along the conveyor chain 1 to flip the battery 4 from an inverted position to an upright position. In the flipping device 2, the gripper 23 clamps the inverted battery 4 and carton 5 on the tray 21, and the rotary motor starts to rotate the gripper 23, thereby flipping the battery 4 and carton 5. After the flip is completed, the gripper 23 releases the upright battery 4 and carton 5, and the battery 4 and carton 5 are conveyed to the sealing device 3 along the tray 21 for sealing.

[0070] It should be noted that the conveyor chain 1 uses a frosted anti-skid power roller for transmission.

[0071] The specific working steps are:

[0072] S100: The upside-down battery 4 and the carton 5 enter the tray 21 along the conveyor chain 1;

[0073] S200: The tray 21 aligns the positions of the inverted battery 4 and the carton 5 to the center;

[0074] S300: The tray 21 lifts the inverted battery 4 and the carton 5 to the position of the gripper 23. The gripper 23 clamps the inverted battery 4 and the carton 5, and the tray 21 returns to the conveyor chain 1.

[0075] S400: The gripper 23 clamps the upside-down battery 4 and the carton 5 and flips them upright;

[0076] S500: The tray 21 rises to catch the upright battery 4 and carton 5. After confirming that the gripper 23 is released, the tray 21 returns to the conveyor chain 1.

[0077] S600: The upright batteries 4 and cartons 5 enter the carton sealing device 3 for sealing.

[0078] In other words, by controllably flipping the inverted battery 4 and carton 5 to an upright position within the flipping device 2 and transporting them to the carton sealing device 3 for sealing, the efficiency of the cartoning process is improved, and damage to the batteries and packaging materials, as well as labor intensity, is reduced. At the same time, automated assembly line operation for the packaging of medium-density batteries is achieved.

[0079] Furthermore, in order to reduce damage to the battery 4 caused by impact in the carton 5, the gripping clamp 23 clamps the upside-down battery 4 and flips the carton 5 to an upright position, further comprising the following steps:

[0080] S410: When the gripper 23 rotates to the first angle, the side pusher 24 on one side of the gripper 23 is inserted into the gripper 23 to impact the battery 4 and the carton 5;

[0081] S420: The side pushing device 24 collides with the carton 5, causing the battery 4 to slide along the carton 5 to the bottom of the carton 5;

[0082] S430: The gripper 23 clamps the battery 4 and the carton 5 and rotates to a second angle.

[0083] The first angle can range from 120° to 150°, and the second angle can range from 30° to 60°. When the gripper 23 clamps the battery 4 and the carton 5 is flipped to the first angle, the battery 4 will slide to the bottom of the carton 5 due to gravity. Furthermore, in order to reduce the friction between the outer wall of the battery 4 and the inside of the carton 5, which causes the battery 4 to not slide down normally to the bottom of the carton 5, the side pusher 24 is used to impact and shake the battery 4 to help it slide slowly to the bottom of the carton 5; secondly, it is to prevent the battery 4 from sliding directly to the bottom of the carton 5 due to a large rotation angle, thereby preventing the impact force generated by the battery 4 breaking through the bottom of the carton 5 and causing the battery 4 to slide out of the carton 5 and fall. Furthermore, when the first angle is 135° and the second angle is 45°, the side pusher 24 and the gripper 232 are placed at a 45° angle, so that the output end of the side pusher 24 enters the inside of the gripper 232 at a 45° angle, impacting and shaking the carton 5, and helping the battery 4 to slide slowly.

[0084] In one embodiment, it includes: a accommodating cavity 211 and a grabbing cavity 231, the accommodating cavity 211 is located in the tray 21, and the grabbing cavity 231 is located in the grabbing clamp 23; and the grabbing cavity 231 is located directly above the accommodating cavity 211; the width of the accommodating cavity 211 is greater than the width of the grabbing cavity 231.

[0085] That is to say, in order to allow the gripper 23 to have enough space to move in the accommodating cavity 211 and to perform the operation of gripping the battery 4 and the carton 5 , it is convenient for the gripper 23 to grip the battery 4 and the carton 5 .

[0086] See Figure 4In one embodiment, the gripper 23 includes: at least two grippers 232 and parallel connecting plates 233; the ends of the grippers 232 are connected to the connecting plates 233; the flip motor 22 is fixed to one side of the connecting plates 233 through a first fixing seat 221; and the gripping cavity 231 is formed between the two corresponding grippers 232.

[0087] It can be understood that two parallel grippers 232 are connected by a connecting plate 233, and the grippers 232 are used to clamp the battery 4 and the carton 5 from both sides toward the middle; when the grippers 232 clamp the battery 4 and the carton 5, the flipping motor 22 is started, causing the connecting plate 233 to rotate with the flipping motor 22, and then causing the grippers 232 to flip, thereby driving the battery 4 and the carton 5 to flip.

[0088] In one embodiment, the gripper 23 further includes: a sliding member 234 and a clamping cylinder are further provided at the end of the gripper 232; the gripper 232 is configured as a C-shaped gripper 232;

[0089] The sliding member 234 slides along the connecting plate 233 ; the output end of the clamping cylinder is connected to the back side of the gripper 232 .

[0090] That is, the gripper 232 is pushed by the clamping cylinder, and the sliding member 234 assists the sliding of the gripper 232, reducing the friction between the gripper 232 and the connecting plate 233, thereby completing the clamping action of the gripper 232. Because the gripper 232 is configured as a C-shaped gripper 232, the gripper 232 has hooks at the upper and lower parts, thereby restricting the movement of the battery 4 and the carton 5 within the gripper 232, i.e., the gripping cavity 231, and preventing the battery 4 and the carton 5 from escaping from the gripper 232.

[0091] In one embodiment, the invention further comprises: a slide rail 235 is fixed to a side of the connecting plate 233 close to the grip 232 ; and the sliding member 234 slides along the slide rail 235 .

[0092] That is to say, the grippers 232 can slide stably along the slide rails 235, and the two parallel and symmetrical slides are realized during the clamping process. Keeping the grippers 232 always in a parallel state can stably clamp the battery 4 and the carton 5.

[0093] In one embodiment, it further includes: a lifting cylinder 212 and a protrusion 213 ; the protrusion 213 is fixed to the surface of the tray 21 ; and the output end of the lifting cylinder 212 is connected to the bottom of the tray 21 .

[0094] The protrusion 213 creates a gap between the battery 4 and carton 5 and the surface of the pallet 21, allowing the gripper 232 to grip through the gap. This allows the gripper 232 to grip the battery 4 and carton 5 completely and without obstruction. The lifting cylinder 212 lifts the pallet 21, allowing the pallet 21 to carry the battery 4 and carton 5 into the gripping chamber 231, waiting for the gripper 23 to clamp the battery 4 and carton 5. After the gripper 232 clamps the battery 4 and carton 5, the lifting cylinder 212 resets and the pallet 21 resets, waiting for the battery 4 and carton 5 to complete the flip. When the battery 4 and carton 5 are flipped and in an upright position, the lifting cylinder 212 lifts the pallet 21, placing the upright battery 4 and carton 5 on the pallet 21. The lifting cylinder 212 resets, and the pallet 21 resets, allowing the upright battery 4 and carton 5 to return to the conveyor chain 1 and be transported to the sealing device 3 for sealing.

[0095] See Figure 5 The carton sealing device 3 includes: a side conveyor belt 31, a bracket 32, a guide member 33 and a baffle 34, wherein the baffle 34 includes a fixed baffle 341 and a movable baffle 342, and the movable baffle 342 is on the side of the fixed baffle 341 away from the bracket 32; the order of placement parallel to the side conveyor belt 31 is the movable baffle 342, the fixed baffle 341, and the guide member 33; the bracket 32 ​​is placed perpendicular to the side conveyor belt 31, and one end of the guide member 33 and the baffle 34 are fixedly connected to the middle part of the bracket 32 ​​respectively. When the upright batteries 4 and carton 5 enter the carton sealing device 3, the side conveyor belt 31 clamps the outer wall of the carton 5 from both sides to the middle, driving the carton 5 to move. The movable baffle 342 is lifted, and the first hinge 51 of the carton 5 is pushed down by the fixed baffle 341 and folded inward. The movable baffle 342 falls and pushes down the second hinge 52 of the carton 5 and folds inward. The third and fourth hinges 53 and 54 of the carton 5 follow the guide 33 and fold inward. Through the cooperation of the movable baffle 342, the fixed baffle 341 and the guide 33, the first, second, third and fourth hinges 51, 52, 53 and 54 are folded inward. The guide 33 is configured as a trumpet shape, and the width decreases as it approaches the bracket 32.

[0096] The carton 5 further includes a tape box 35, which is located on a side of the fixed baffle 341 away from the movable baffle 342. When the first, second, third, and fourth hinges 51, 52, 53, and 54 of the carton 5 are folded inward, the entrance of the tape box 35 begins applying tape from the direction of the first hinge 51 of the carton 5 to the second hinge 52 of the carton 5. When the second hinge 52 is attached, the exit of the tape box 35 cuts the tape. This completes the sealing of the carton 5 and the packaging of the batteries 4.

[0097] The first sensor 214 and the second sensor 36 can be used to confirm whether the battery 4 and the carton 5 leave or return to the pallet 21, control the operation of the lifting cylinder 212, and whether the carton 5 enters the sealing device 3. The sensor 2124 can be a gravity sensor, an infrared sensor, etc.

[0098] See Figure 6 To prevent the grippers 232 from making errors during gripping and damaging the outer wall of the carton 5, one embodiment further includes a calibration structure 215 fixedly connected to the edge of the tray 21. The accommodating cavity 211 is formed between two corresponding calibration structures 215. The calibration structures 215 push toward the center from both sides, positioning the inverted battery 4 and carton 5 in the center of the tray 21, where they can be grasped by the grippers 232.

[0099] See Figure 3 In one embodiment, the invention further comprises: a side pushing device 24; the output end of the side pushing device 24 can enter the grabbing cavity 231; and the side pushing device 24 is located on one side of the grabbing hand 232;

[0100] The output end of the side pushing device 24 contacts the outer surface of the inverted battery 4 and the carton 5 .

[0101] See Figure 4 In one embodiment, the gripper 232 further includes: a hollow portion 236, and the output end of the side thrust device 24 enters the gripping cavity 231 through the hollow portion 236 to contact the outer surface of the inverted battery 4 and the carton 5, thereby being able to impact and shake the carton 5, so that the battery 4 in the carton 5 slowly slides to the bottom of the carton 5, and can also slow down the speed at which the carton 5 slides in the gripper 23, thereby reducing the possibility of the carton 5 being damaged and detached from the gripper 232.

[0102] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
