[0001] The invention relates to the technical field of battery manufacturing, in particular to a battery manufacturing device and process. Background Art

[0002] The battery shell of the lead-acid battery includes a battery slot and an upper cover. The combination of the battery slot and the upper cover is achieved by processing under a heat sealing machine. The working mode of the heat sealing machine is to melt the heat-sealed joint surface of the upper cover and the battery slot through a heating plate, and then squeeze the hot upper cover and battery slot with a certain pressure to achieve the overall heat sealing of the battery shell.

[0003] The current battery heat sealing is generally completed by a battery heat sealing machine. Specifically, after the battery body is loaded into the battery slot, the upper cover is pre-placed and covered on the upper port of the battery slot. Then the conveyor belt will control the battery shell and the internal battery body to move to the inside of the battery heat sealing machine, so that the upper cover moves with the battery shell to just below the shell grabbing mechanism, the conveyor belt is stopped, and the shell grabbing mechanism is controlled to grab the upper cover at the upper port of the battery slot and move it up, then the heating plate is controlled to move between the battery slot and the upper cover, then the heating plate and the upper cover are controlled to move down and contact each other, the heating plate is energized to heat and melt the joint surface of the upper cover and the battery slot, then the heating plate and the upper cover are moved up, and after the heating plate is controlled to move away, the upper cover is controlled to move down and cover the upper port of the battery slot, completing the battery heat sealing manufacturing process.

[0004] It is not difficult to find that before heat sealing the battery, the upper cover needs to be covered on the corresponding upper port of the battery slot in sequence before it can enter the battery heat sealing machine for heat sealing, and before heating the upper cover and the battery slot each time, it is necessary to grab the upper cover of the battery slot notch and move it up to separate it, resulting in low efficiency of current battery heat sealing, which is not suitable for large-scale battery manufacturing.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 9 As shown, the present invention includes the following embodiments:

[0035] Embodiment 1: A battery manufacturing device, comprising a body 1 and a conveying trough 11 extending through the body 1; a conveying belt 2 is connected to the conveying trough 11 in a lateral transmission manner; the conveying belt 2 is driven by a motor 21; a heating plate 3 is connected to the body 1 in a controlled manner by a control component 31; a feeding trough 12 connected to the conveying trough 11 is provided through the body 1 from top to bottom; the feeding trough 12 is located directly above the conveying belt 2; a feeding frame 4 is movably connected to the feeding trough 12 from top to bottom; the feeding frame 4 There are rectangular openings on the top and bottom; a hydraulic cylinder 41 is vertically fixedly connected between the outer wall of the loading frame 4 and the inner wall of the loading trough 12; the inner wall of the loading frame 4 is vertically provided with a clamping groove 42; the clamping groove 42 penetrates the loading frame 4 downward; the clamping strip 5 is movably connected in the clamping groove 42; the outer wall of the loading frame 4 is fixedly connected to an electric push rod 43; the electric push rod 43 passes through the loading frame 4 and is fixedly connected to the clamping strip 5; the clamping strip 5 can move towards or away from the center of the loading frame 4 under the drive of the electric push rod 43.

[0036] Before heat sealing the battery, turn off the heating plate 3, so that the heating plate 3 moves to the lower port of the loading frame 4 under the control of the control component 31, and the heating plate 3 blocks the lower port of the loading frame 4, and then put the stacked upper cover along the upper port of the loading frame 4, and the upper port of the loading frame 4 is provided with a chamfer, so that the stacked upper cover can smoothly enter the inner side of the loading frame 4, and the stacked upper cover will fall on the heating plate 3, and the lowermost upper cover of the stacked upper cover will contact the heating plate 3, and then the electric push rod 43 is controlled to extend, and the electric push rod 43 will drive the clamping bar 5 away from the bottom of the corresponding clamping groove 42 during the extension process, so that the clamping bar 5 moves toward the center of the loading frame 4, and multiple clamping bars 5 are clamped at the four edges of the upper cover to achieve clamping of the stacked upper cover within the range of the clamping groove 42, thus completing the loading process of multiple upper covers;

[0037] After the staff loads the battery body into the battery slot, the battery body and the battery slot are sequentially conveyed to the upper surface of the conveyor belt 2. The conveyor belt 2 passes through the conveying slot 11 on the side of the body 1, so that the battery slot will drive the battery body to be sequentially conveyed to the bottom of the loading frame 4 along with the conveyor belt 2, and then the transmission of the conveyor belt 2 is stopped, and then the control component 31 drives the heating plate 3 to move down, and the hydraulic cylinder 41 drives the loading frame 4 to move down. After the heating plate 3 moves down, it contacts the upper port of the battery slot. The heating plate 3 keeps moving down synchronously with the loading frame 4 until the heating plate 3 contacts the upper cover on the upper surface and the battery slot below. Then the heating plate 3 is controlled to heat, and the heating plate 3 will heat the heat-sealed bonding surface of the lower surface of the upper cover. The heating plate 3 also heats the heat-sealed bonding surface of the upper port of the battery slot at the same time. The bottom cover in the stacked covers will transfer heat to other covers during the heating process, so as to preheat the other covers.

[0038] After the heating of the upper cover and the battery slot is completed, the control component 31 controls the heating plate 3 to move upward, and the hydraulic cylinder 41 drives the loading frame 4 to move upward. After the heating plate 3 is separated from the battery slot, the heating plate 3 stops moving upward, and after the loading frame 4 is separated from the heating plate 3, the loading frame 4 stops moving upward. Then, the heating plate 3 moves backward under the control of the control component 31, so that the heating plate 3 is moved away from between the loading frame 4 and the battery slot. Then, the hydraulic cylinder 41 is controlled to extend and drive the loading frame 4 to move downward. During the downward movement of the loading frame 4, the stacked upper covers on the inner side will be driven to move downward. The stacked upper covers are clamped by the clamping strips 5 on the inner side of the loading frame 4. After the stacked upper covers move downward, they contact the upper port of the battery slot, and the lowermost upper cover is closed on the upper port of the battery slot. As the upper cover and the battery slot are closed, the heat sealing process of a single battery is completed.

[0039] During the closing process of the upper cover and the battery slot, the staff can supplement the upper cover in the feeding slot 12, and then control the electric push rod 43 to shorten. During the shortening process of the electric push rod 43, the clamping strip 5 will be driven away from the center of the feeding frame 4, so as to release the clamping strip 5 from the upper cover within the clamping slot 42. As the clamping strip 5 retracts into the clamping slot 42, the upper cover supplemented from the upper port of the feeding frame 4 will move down and contact the upper cover stacked at the lower position on the inner side of the feeding frame 4 to supplement the upper cover. Then the feeding frame 4 is controlled to move up one upper cover, and the electric push rod 43 is controlled to extend to drive the clamping strip 5 to clamp the upper cover within the clamping slot 42. Then the feeding frame 4 is continued to be controlled to move up, and the conveyor belt 2 will drive the heat-sealed storage battery to be removed, and the new battery slot is moved to the bottom of the feeding frame 4. After controlling the heating plate 3 to heat the heat-sealed joint surface of the upper cover and the battery slot, heat-seal again, and repeat the above process.

[0040] The present invention uses the upper covers stacked in the loading frame 4, so that after the battery body moves to the bottom of the loading frame 4 along with the battery slot, the heated upper cover is directly covered with the heated battery slot to complete the heat sealing process of the battery. Compared with the existing heat sealing process, the steps of pre-covering the upper cover on the notch of the battery slot and removing it are saved, thereby improving the heat sealing efficiency of the battery; in addition, during the heating process of the lowermost upper cover, the upper cover can be preheated, thereby improving the subsequent heating efficiency of the upper cover, so that the heat sealing efficiency of the battery is indirectly improved.

[0041] Embodiment 2: The four surfaces of the lower port of the loading frame 4 are all provided with guide strips 6; the guide strips 6 are arranged away from the center of the loading frame 4 from top to bottom.

[0042] In this embodiment, an avoidance groove 44 is provided at the lower end of the clamping strip 5 toward the center of the loading frame 4; the avoidance groove 44 passes through the loading frame 4; the guide strip 6 is arc-shaped; the upper end of the guide strip 6 is located in the avoidance groove 44; the upper end of the guide strip 6 is hinged to the lower end of the clamping strip 5 through a torsion spring 61.

[0043] In the process of the new battery slot moving to the bottom of the loading frame 4 along with the conveyor belt 2, the heating plate 3 is moved to the bottom of the loading frame 4 under control. As the new battery slot moves to the bottom of the loading frame 4, the heating plate 3 and the loading frame 4 are controlled to move downward. After the heating plate 3 moves downward, it will contact the upper port of the battery slot. After the loading frame 4 moves downward, it will drive the stacked upper cover and the guide bar 6 to move downward. The lower end of the guide bar 6 contacts the heating plate 3 as the loading frame 4 moves downward. The guide bar 6 is made of metal and will not melt as the heating of the heating plate 3 is heated. As the loading frame 4 continues to move downward, the lower end of the guide bar 6 is squeezed to overcome the torsion spring 61 and rotate. The guide bar 6 will flip around the upper end of the guide bar 6 during the flipping process. The guide bar 6 will fall into the avoidance groove 44 for avoidance during the flipping process.

[0044] In this way, the upper cover is in contact with the heating plate 3. After the joint surface of the upper cover and the battery slot is heated, the loading frame 4 and the heating plate 3 are controlled to move upward. When the loading frame 4 moves away from the heating plate 3, the guide bar 6 is reset under the action of the torsion spring 61. As the heating plate 3 moves backward to avoid it, the loading frame 4 is controlled to move downward. After the loading frame 4 moves downward, it will drive the guide bar 6 to move downward. During the downward movement of the guide bar 6, the deviated battery slot will be squeezed to move. The torsion force of the torsion spring 61 is greater than the gravity of the battery slot and the battery body inside the battery slot. In this way, the inner side of the guide bar 6 can squeeze the battery slot, so that the battery slot drives the internal battery body to move toward the bottom of the upper cover, and the The battery slot position is calibrated before heat sealing. As the loading frame 4 continues to move downward, the loading frame 4 will drive the upper cover to close on the corrected upper port of the battery slot. The upper end of the guide bar 6 is connected to the lower end of the clamping bar 5. Therefore, when the clamping bar 5 clamps upper covers of different specifications, the guide bar 6 can still calibrate the position of battery slots of different specifications. In this embodiment, the guide bar 6 is placed in the avoidance groove 44 during the heating process of the upper cover, and the battery slot is calibrated before the upper cover is heat-sealed, thereby avoiding the position deviation caused by the upper cover closing the battery slot, greatly improving the smoothness and effect of battery heat sealing.

[0045] Embodiment 3: A side of the clamping strip 5 close to the center of the loading frame 4 is provided with an anti-slip groove 51; an anti-slip block 52 is slidably connected in the anti-slip groove 51; the anti-slip block 52 is connected to the bottom of the anti-slip groove 51 by a spring 53; the distance between the lower surfaces of adjacent anti-slip blocks 52 is equal to the thickness of the upper cover; the distance between the lower surface of the lowest anti-slip block 52 and the lower port of the loading frame 4 is adapted to the thickness of the upper cover.

[0046] The height of the stacked upper covers inside the loading frame 4 does not exceed the range of the clamping groove 42. After the lowermost upper cover in the stacked upper covers and the battery slot notch are heated, the heating plate 3 will move backward, and the loading frame 4 will drive the stacked upper covers to move downward. During the downward movement of the stacked upper covers, the lowermost upper cover will be driven to contact with the battery slot notch. During the contact between the lowermost upper cover and the battery slot notch, in order to increase the force of the upper cover covering the battery slot, the force during the downward movement of the loading frame 4 will be transmitted to the clamping bar 5. During the process of the clamping bar 5 clamping the stacked upper covers, the stacked upper covers will block part of the anti-slip groove 51, so that the anti-slip blocks 52 within the range of the stacked upper covers will retract into the anti-slip groove 51 for avoidance. The anti-slipping block 52 that is not within the range of the stacked upper cover extends out of the anti-slipping groove 51 under the action of the spring 53, and the anti-slipping block 52 can limit the top upper cover of the stacked upper cover, so that the stacked upper cover cannot move up relatively in the loading frame 4, avoiding the stacked upper cover and the inner side of the loading frame 4 from slipping. In this way, when the loading frame 4 drives the stacked upper cover close to the battery slot, the loading frame 4 will transfer the downward force to the anti-slipping block 52 through the clamping strip 5, so that the anti-slipping block 52 will transfer the force to the upper surface of the top upper cover, so that the stacked upper cover moves downward with greater force, ensuring the covering force of the bottom upper cover on the battery slot and ensuring the smooth heat sealing of the battery;

[0047] After completing the heat sealing of one of the batteries, the electric push rod 43 is controlled to shorten, and the electric push rod 43 will drive the clamping strip 5 to retract into the clamping groove 42. The thickness of the clamping strip 5 is less than the depth of the clamping groove 42, so the clamping strip 5 can drive the anti-slip block 52 on the outside of the anti-slip groove 51 to return to the clamping groove 42 for avoidance, so that the anti-slip block 52 above the stacked upper cover is removed, so that the new upper cover can enter the loading frame 4 from top to bottom. After completing the replenishment of the upper cover, the loading frame 4 moves up one upper cover position, and the clamping strip 5 is controlled to be close to the center of the loading frame 4. The clamping strip 5 clamps the stacked upper cover, and the anti-slip block 52 at the position where the clamping strip 5 does not contact the upper cover extends out of the anti-slip groove 51, thereby ensuring the limiting effect of the stacked upper cover.

[0048] Embodiment 4: The four inner walls of the loading frame 4 are penetrated outwardly with movable grooves 45; the upper end of the movable groove 45 is close to the upper port of the loading frame 4, and the lower end of the movable groove 45 is higher than the electric push rod 43; the movable groove 45 is movably connected to the movable block 7; the upper surface of the movable block 7 and the upper end of the movable groove 45 are connected by a tension spring 71; the groove wall of the movable groove 45 is provided with a guide groove 46; the upper end of the guide groove 46 is close to the center of the loading frame 4, and the lower end of the guide groove 46 is far away from the center of the loading frame 4; the guide block 72 is movably connected in the guide groove 46; the guide block 72 is fixedly connected to the movable block 7.

[0049] In this embodiment, the outer wall of the loading frame 4 is slidably connected to the square frame 8; radial grooves 81 are provided on the upper surface of the square frame 8 and at positions corresponding to the movable blocks 7; the movable blocks 7 are slidably connected in the radial grooves 81; and the plurality of movable blocks 7 move up and down synchronously.

[0050] In this embodiment, the movable block 7 is arranged to be inclined upward at one end close to the center of the loading frame 4; the upper half of the guide groove 46 is corrugated; the guide block 72 will move back and forth towards and away from the center of the loading frame 4 during the movement of the upper half of the guide groove 46; the lower half of the guide groove 46 is straight; the guide block 72 will move away from the center of the loading frame 4 during the movement of the lower half of the guide groove 46.

[0051] After the clamping strip 5 is retracted away from the feeding frame 4 to the corresponding clamping groove 42, the staff will supplement the upper cover in the feeding frame 4 according to the needs. Before the upper cover is supplemented, the movable block 7 is located at the inner side of the feeding frame 4 near the slot position. As the new stacked upper cover falls from the upper end of the feeding frame 4, the new stacked upper cover will fall on the upper surfaces of multiple movable blocks 7. The new stacked upper cover has a large gravity, so that the multiple movable blocks 7 can overcome the tension of the tension spring 71 and move downward under the action of the gravity of the new stacked upper cover. The multiple movable blocks 7 are slidably connected to the same square frame 8, so the multiple movable blocks 7 will move downward synchronously, and the movable block 7 will drive the guide block 72 to move in the guide groove 46. The upper half of the guide groove 46 is corrugated. Therefore, during the downward movement of the guide block 72 along the upper half of the guide groove 46, the guide block 72 will move back and forth towards and away from the center of the feeding frame 4. During the movement of the guide block 72 away from the center of the feeding frame 4, the inclined surface on the movable block 7 contacts and moves with the new stacked upper cover, so that the new stacked upper cover further sinks relative to the movable block 7;

[0052] The guide block 72 will drive the movable block 7 away from the center of the loading frame 4, so that the end of the movable block 7 close to the center of the loading frame 4 will retract into the movable groove 45 for avoidance, so that the newly stacked upper cover passes over the movable block 7 and falls on the upper surface of the residual upper cover in the loading frame 4;

[0053] The guide block 72 is used to support and buffer the newly added upper cover and then move it downward, so that the upper cover in the feeding frame 4 is prevented from being damaged by violent loading during the new replenishment process, thereby protecting the upper cover. In addition, the movable block 7 moves close to and away from the center of the feeding frame 4 during the downward movement, so that the stacked upper covers are in closer contact after the loading is completed, ensuring the subsequent upper cover preheating effect. The synchronous downward movement of multiple movable blocks 7 is also to avoid the upper cover in the feeding frame 4 from being stuck due to tilting during the replenishment process, so that the upper cover in the feeding frame 4 is replenished more smoothly;

[0054] As the upper covers in the loading frame 4 are consumed, after the top upper cover of the stacked upper covers is consumed below the lower end of the movable slot 45, the movable block 7 is pulled upward by the tension spring 71 without any obstruction. The tension spring 71 will drive the corresponding movable block 7 to move to the upper end of the movable slot 45. After the movable block 7 moves upward, it contacts with the upper end of the movable slot 45 to form a collision and produce a collision sound, so that the staff can add a new upper cover according to the prompt of the collision sound.

[0055] It should be noted that the tension of the tension spring 71 in this embodiment is smaller than the gravity of the upper cover.

[0056] Embodiment 5: A battery manufacturing process, which is applicable to the above-mentioned battery manufacturing equipment, and the steps of the process are as follows:

[0057] S1: After the battery body is loaded into the battery slot, the battery body and the battery slot are sequentially conveyed to the upper surface of the conveyor belt 2. The battery slot drives the battery body to be sequentially conveyed to the feeding frame 4 and directly below the heating plate 3 along the conveyor belt 2;

[0058] S2: The control component 31 drives the heating plate 3 to move downward, and the hydraulic cylinder 41 drives the loading frame 4 to move downward. After the heating plate 3 moves downward, it contacts the upper port of the battery slot. The heating plate 3 keeps moving downward synchronously with the loading frame 4 until the heating plate 3 contacts the upper cover on the upper surface and the battery slot below.

[0059] S3: Controlling the heating plate 3 to heat the heat-sealed joint surface of the lower surface of the upper cover, and the heating plate 3 also heats the heat-sealed joint surface of the upper port of the battery slot at the same time, and the bottom upper cover of the stacked upper covers transfers heat to other upper covers during the heating process;

[0060] S4: After the heating plate 3 is controlled to move backward and avoid, the loading frame 4 moves downward, which will drive the inner stacked upper cover to move downward, and the lowermost upper cover inside the loading frame 4 is closed on the battery slot to complete the heat sealing of the battery.
