Description

Technical Field

[0001] The invention relates to the technical field of battery processing equipment, and in particular to a battery drying production line. Background Art

[0002] During the use of batteries, the sealing part of the battery will come into contact with moisture in the air, causing rust. To avoid this, anti-rust oil is usually applied to the sealing part of the battery, and then the batches of oiled batteries are dried to form a protective layer. How to ensure the drying quality while improving the drying efficiency is what companies need to pay attention to in order to improve battery quality.

[0003] The prior art discloses a Chinese utility model patent with the announcement number CN212006514U and the patent name of a tray and drying device for lithium-ion batteries, which specifically discloses a tray frame and a plurality of battery support rods arranged between the inner side walls of the tray frame, wherein the distance between the battery support rods is adapted to the size of the bottom surface of the lithium-ion battery. The lithium-ion battery drying device comprises: a box body and a heating plate integrated in the box body, wherein the size of the heating plate is less than or equal to the inner size of the tray frame of the lithium-ion battery drying tray described in the claim, wherein the surface of the heating plate has a plurality of grooves corresponding to the battery support rods, wherein the size of the cross section of the groove perpendicular to the length direction is greater than or equal to the size of the cross section of the battery support rod perpendicular to the length direction.

[0004] The above solution realizes direct heating of the lithium-ion battery by the heating plate, avoiding the heat transfer problem of the drying carrier, thereby achieving a better drying effect and higher energy utilization rate.

[0005] Another example is the Chinese invention patent with the announcement number CN113426646A and the patent name "Drying device installed in a lithium battery cap coating machine", which specifically discloses a workbench, a base is fixedly installed at the bottom of the workbench, a mounting plate is fixedly installed on the top of the workbench, a first fixed plate and a second fixed plate are fixedly installed on the mounting plate, and a plurality of first fans are fixedly installed at the bottom of the first fixed plate.

[0006] The above scheme places the glue-coated caps in a tray, places the tray on a workbench and is located below a drying mechanism, and is dried by the drying mechanism. After drying, the tray is moved to the workbench and is located below a first fan, and the first fan is started to cool the caps. Natural heat dissipation is not used, and the caps are cooled by the first fan. The heat dissipation efficiency is fast, the heat dissipation effect is good, the production time is reduced, and the production efficiency is improved.

[0007] However, in actual use, the batteries in the battery tray can only be heated and dried one by one. In the automated battery production line, there are a large number of battery trays, and the method of drying them one by one will undoubtedly reduce the overall processing efficiency of the batteries.

[0008] Therefore, a battery drying production line is proposed to solve the above-mentioned problems. Summary of the invention

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0046] The present invention will be further described below in conjunction with the embodiments.

[0047] Embodiment 1:

[0048] This embodiment specifically describes the structure of a battery drying production line.

[0049] Please see attached Figure 1-14 , mainly includes a frame 1, a conveyor belt 3 and an oven 4. A conveying platform 2 for conveying the battery tray 10 is provided on one side of the frame 1.

[0050] See attached Figure 1The conveying platform 2 in this case includes an upper platform and a lower platform which are arranged up and down and transmit in the same direction; the conveyor belt 3 is arranged on the frame 1, and its transmission direction is perpendicular to the transmission direction of the conveying platform 2.

[0051] There are several rollers for transmitting the battery tray 10 at intervals on the lower platform, and a grabbing structure that can grab the battery tray 10 on the roller to the conveyor belt 3 is provided on the upper platform. The grabbing structure in this case can be linearly displaced along the transmission direction of the conveying platform 2 and can also be lifted up and down in the vertical direction. The conveyor belt 3 is vertically arranged between the upper platform and the lower platform. The staff places the battery tray 10 on the shaft roller in the lower platform, uses the grabbing structure on the upper platform to clamp the battery tray 10, and moves toward one side of the conveyor belt 3. When it reaches the top of the conveyor belt 3, the battery tray 10 is put down. The conveyor belt 3 can be in various ways such as belts and shaft rollers, which are not specifically limited here.

[0052] The setting of the upper and lower platforms and the grabbing structure is a known technology. In this case, the upper platform includes a truss structure arranged above the lower platform, and a linearly movable bracket is provided on the truss, and the grabbing structure is arranged on the movable bracket. The moving method of the movable bracket is not limited here, and various methods such as screw rods and push rods can be used.

[0053] The grasping structure includes two symmetrically arranged clamping claw structures that can move toward each other on a movable bracket. The movable bracket is provided with a driving mechanism for linear movement of the clamping claw structure, which is not specifically limited here. In this case, a slide rail is provided on the movable bracket, and the clamping claw structure slides on the slide rail.

[0054] See attached Figure 3 The conveyor belt 3 is connected to one side of the conveying platform 2 and is used to transmit the battery tray 10 transported from the conveying platform 2. The battery tray 10 is transmitted at intervals on the conveyor belt 3, and the conveyor belt 3 stops intermittently.

[0055] A stacking unit is provided on the conveyor belt 3, and the stacking unit includes two symmetrically distributed transfer jaws 31. The two transfer jaws 31 can move toward each other and clamp the battery tray 10 located on the conveyor belt 3, and each transfer jaw 31 can be vertically lifted and lowered along the height direction of the conveyed battery tray 10.

[0056] When the battery tray 10 on the conveyor belt 3 moves between the two transfer jaws 31, the two transfer jaws 31 move toward each other and are fixed on the battery tray 10 at the same time. After being fixed to the battery tray 10, the two transfer jaws 31 clamp the battery tray 10 and rise. At this time, the conveyor belt 2 continues to transmit. When the next battery tray 10 moves back between the two transfer jaws 31 (at this time it is located at the bottom), the transfer jaws 31 release the fixation and restraint of the current battery tray 10, allowing the battery tray 10 located above to be placed on the battery tray 10 located below to form a stack.

[0057] At this time, the transfer clamp 31 descends again and fixes the battery tray 10 located below and rises again with the two battery trays 10 above. The conveyor belt 2 continues to transmit, and the transfer clamp 31 repeats the above process until the battery tray 10 lifted by the transfer clamp 31 reaches a certain height. At this time, the transfer clamp 31 releases the restraint on the lowest battery tray 10 and uses the conveyor belt 2 to move the battery tray 10 at a certain height away.

[0058] The conveyor belt 3 may be provided in a variety of ways, such as a belt, a roller, etc., which are not specifically limited here. In this case, two conveyor belts 3 are provided, and the two conveyor belts 3 are distributed in parallel, and the battery tray 10 is transmitted on the two conveyor belts 3.

[0059] See attached Figure 3 In order to realize the one-by-one transmission of the battery trays 10, in this case, at least one vertically liftable limit plate 32 is provided on the conveyor belt 3, and an electric push rod is provided at the bottom of the limit plate 32 for realizing the up and down lifting of the limit plate 32.

[0060] Embodiment 2:

[0061] This embodiment is based on Embodiment 1 and further describes the specific structure of the oven 4.

[0062] See attached Fig. 9 The oven 4 is arranged on the other side of the conveyor belt 3 and has an opening at its upper end, and a group of first conveyor belts 41 are respectively arranged on both sides of the opening at the upper end of the oven 4, and the transmission directions of the two groups of first conveyor belts 41 are the same as the transmission direction of the conveyor belt 3 and the distance between the two groups of first conveyor belts 41 is adjustable.

[0063] See attached Fig.10 Specifically, a fixed clamp 42 is provided on both sides of the upper opening of the oven 4 , and the two fixed clamps 42 can move toward each other and fix the battery tray 10 between the two fixed clamps 42 .

[0064] See attached Fig.11When the battery trays 10 stacked on the conveyor belt 3 move to the first conveyor belt 41, the two fixed jaws 42 move toward each other and fix the lowest battery tray 10. In this case, a tray 5 that can be vertically lifted and lowered along the height direction of the oven 4 is provided in the oven 4. The moving path of the tray 5 is perpendicular to the conveyor belt 3. At this time, the tray 5 rises and supports the lower end of the stacked battery trays 10. At this time, the two fixed jaws 42 release the lock on the battery tray 10, and the two first conveyor belts 41 move in opposite directions. The tray 5 will begin to descend and transport the battery tray 10 on the first conveyor belt 41 to the inside of the oven 4.

[0065] In this case, two sliders that can move toward each other are arranged above the oven 4, and two groups of first conveyor belts 41 are respectively fixed on the two sliders, and an electric drive mechanism is arranged on the other side of the slider. The electric drive mechanism used for linear pushing of objects is a well-known technology and is not specifically limited here. Devices such as screw rods or electric push rods can be used.

[0066] Embodiment 3:

[0067] This embodiment is based on the first embodiment and further describes the specific structure of the retaining member.

[0068] See attached Figure 7 A stopper is provided on the conveyor belt 3 to prevent the battery tray 10 from retreating on the conveyor belt 3, and the stopper is located on the transmission path of the battery tray 10; wherein the stopper includes a baffle 33 elastically hinged at the middle part of the conveyor belt 3, and the end face of the baffle 33 away from the oven 4 is an inclined surface, and the inclined surface is located on the transmission path of the battery tray 10.

[0069] When the battery tray 10 is transmitted on the conveyor belt 3, the battery tray 10 will conflict with the inclined surface on the baffle 33 and allow the baffle 33 to rotate a certain angle. When the battery tray 10 has a certain tendency to retreat, the battery tray 10 has moved to the other side of the baffle 33. At this time, the baffle 33 is reset under the action of elasticity, and the other end face of the baffle 33 is parallel to the side end face of the battery tray 10. Therefore, once the battery tray 10 retreats, it will conflict with the back side of the baffle 33, and the baffle 33 is difficult to rotate at this time, so it can limit the retreat of the battery tray 10.

[0070] It is worth mentioning that in this case, the baffle 33 can also be set as a one-way rotation mechanism, and the elastic hinge structure and the one-way rotation structure are common knowledge and are not specifically limited here and are not shown in the drawings.

[0071] In this case, the distance between the baffle 33 and the oven 4 can be adjusted according to actual needs. A slide rail structure is provided at the bottom of the baffle 33, which can slide linearly on the conveyor belt 3 and can be locked. The specific locking method is a well-known technology and will not be described here. It can be achieved by providing an electric push rod structure on the rear side of the baffle 33.

[0072] See attached Fig. 9 It should be noted that a guide plate 411 is provided at one end of each set of first conveyor belts 41 facing the conveyor belt 3, and the guide plates 411 on the two first conveyor belts 41 are in an eight-shaped structure with the wide side facing the side of the conveyor belt 3. During the transmission process, the battery tray 10 may deviate from the initial displacement trajectory and get stuck between the two sets of first conveyor belts 41. The two eight-shaped guide plates 411 play a correction function to a certain extent, making it convenient for the battery tray 10 to smoothly enter the top of the two first conveyor belts 41.

[0073] See attached Fig.11 Furthermore, a second conveyor belt 43 for delivering the battery tray 10 inside the oven 4 is provided in the oven 4; wherein the second conveyor belt 43 includes a plurality of rows of fixed columns 431 arranged along the conveying direction of the second conveyor belt 43, the fixed columns 431 are vertically arranged in the oven 4 and a roller 432 is provided at the upper end thereof, and each row of fixed columns 431 includes two symmetrical fixed columns 431.

[0074] The tray 5 in the present case includes two parallel supporting arms, which are located between two adjacent rows of fixed columns 431, so that the tray 5 can be moved to the bottom of the roller 432, that is, the battery tray 10 supported by the tray 5 is placed on the top of the roller 432, and the battery tray 10 can be removed from the oven 4 by utilizing the rotation of the roller 432.

[0075] See attached Figure 2 In this case, a bayonet 101 is provided on the left and right sides of the side end surface of the battery tray 10 , and a fixing port 102 that cooperates with the transport clamp 31 and the fixing clamp 42 is provided in the middle of the bayonet 101 .

[0076] In addition, in order to facilitate the stacking of battery trays 10, a right-angled support plate is vertically arranged at the four corner ends of the upper end of the battery tray 10, and the concave surface of the support plate faces the middle of the battery tray 10. In this way, when stacking, the bottom end surface of the upper battery tray 10 will be placed on the support plate at the upper end of the lower battery tray 10. Since the battery has a certain height after being inserted into the battery tray 10, a space for placing the battery is formed between the two battery trays 10.

[0077] The other side of the oven 4 is provided with a transmission mechanism that is connected to the second conveyor belt 43 and continues to transport the objects out of the oven 4. This is a well-known technology and will not be described in detail here.

[0078] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
