Description

Technical Field

[0001] The utility model relates to the technical field of battery processing equipment, in particular to battery drying equipment. 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 batch 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] Prior art discloses a Chinese utility model patent, CN212006514U, entitled "Lithium-ion Battery Drying Tray and Drying Device." The patent specifically discloses a tray frame and several battery support rods arranged between the inner sidewalls of the tray frame, with the distance between the battery support rods commensurate with the bottom dimensions of the lithium-ion batteries. The lithium-ion battery drying device comprises a housing and a heating plate integrated within the housing. The heating plate's dimensions are smaller than or equal to the inner dimensions of the tray frame of the lithium-ion battery drying tray described in the claim. The heating plate's surface has several grooves corresponding to the battery support rods, with the dimensions of the grooves' cross-sections perpendicular to the length of the battery support rods being greater than or equal to the dimensions of the cross-sections perpendicular to the length of the battery support rods.

[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 better drying effect and higher energy utilization rate.

[0005] 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.

[0006] Therefore, a battery drying device is proposed to solve the above problems. Utility Model Content

[0035] The present invention will be further described below with reference to the embodiments.

[0036] Example 1:

[0037] This embodiment specifically describes a battery drying device.

[0038] Please see the attached Figure 1-6 , mainly including an oven 1 and a grabbing mechanism 2. The oven 1 in this case is hollow inside and has an open upper end. A hot air inlet is provided inside the oven 1 for heating the inside of the oven 1.

[0039] See attached Figure 3A transmission belt 103 for conveying the battery tray 10 is provided on one side of the upper end of the oven 1. The battery tray 10 on the transmission belt 103 has multiple battery insertion slots, each of which is filled with batteries. The grasping mechanism 2 includes two clamping jaws 21 movably installed on both sides of the upper opening of the oven 1. When the battery tray 10 on the transmission belt 103 moves to the upper opening of the oven 1, the two clamping jaws 21 will clamp the battery tray 10 and fix it.

[0040] A tray 5 is provided in the oven 1 and can be lifted vertically along the height direction of the oven 1 . The moving path of the tray 5 is located between the two clamps 21 and can carry the battery tray 10 fixed by the two clamps 21 into the oven 1 .

[0041] Specifically, a group of first conveyor belts 11 are respectively provided on both sides of the upper opening of the oven 1. The transmission direction of the two groups of first conveyor belts 11 is the same as the transmission direction of the transmission belt 103. When the battery tray 10 on the transmission belt 103 is detached from the transmission belt 103, the two sides of the bottom end of the battery tray 10 will be placed above the two groups of first conveyor belts 11 and continue to be transmitted forward with the transmission of the first conveyor belt 11.

[0042] See attached Figure 5 When the battery tray 10 moves to the top of the upper opening of the oven 1, the two clamps 21 will first fix the battery tray 10, and the tray 5 will rise to the bottom of the battery tray 10 and contact it. At this time, the two sets of first conveyor belts 11 are driven to move in opposite directions until the battery tray 10 is completely out of the top of the two sets of first conveyor belts 11. Then the two clamps 21 release the fixation of the battery tray 10, and let the tray 5 move downward with the battery tray 10.

[0043] See attached Figure 3 In this case, a concave slot 101 is provided on each side of the battery tray 10 , and the two clamping jaws 21 can move toward each other and respectively cooperate with the slots 101 on both sides of the battery tray 10 .

[0044] Two sliders that can move toward each other are provided above the oven 1, and two sets of first conveyor belts 11 are fixed on these two sliders respectively. An electric drive mechanism is provided on the other side of the slider. The electric drive mechanism for linearly pushing objects is a well-known technology and is not specifically limited here. Devices such as screw rods or electric push rods can be used.

[0045] Example 2:

[0046] This embodiment is based on the embodiment 1 and further explains the first door stop 3 for distinguishing the workstations. A first door stop 3 that can be lifted vertically is provided between the oven 1 and the transmission belt 103. The upper end of the first door stop 3 is connected to an electric push rod for driving the first door stop 3 to move up and down.

[0047] It should be noted that, see the attached Figure 2 In this case, a guide plate 111 is provided at one end of the first conveyor belt 11 facing the transmission belt 103. The guide plates 111 on the two first conveyor belts 11 are in an eight-shaped structure with the wide side facing the transmission belt 103. 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 11. The two eight-shaped guide plates 111 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 11.

[0048] See attached Figure 3 In this case, in order to facilitate the stacking of battery trays 10, a right-angled support plate 102 is vertically provided at the four corner ends of the upper end of the battery tray 10, and the concave surface of the support plate 102 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 102 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.

[0049] When the battery tray 10 enters the oven 1 due to the lowering of the tray 5, the clamp 21 will clamp another battery tray 10 and wait for the tray 5 to rise again with the battery trays 10 carried above it for stacking. When the battery trays 10 above the tray 5 are stacked to a certain height, the tray 5 and the battery trays 10 carried above it enter the oven 1 together, and then hot air is injected into the oven 1 for drying. In this way, drying operations can be carried out in batches, reducing energy loss.

[0050] See attached Figure 5 A second conveyor belt 12 is provided inside the oven 1 for conveying the battery trays 10 inside the oven 1. The stacked battery trays 10 are located on the second conveyor belt 12. After drying is completed, the second conveyor belt 12 starts working and conveys the stacked battery trays 10 out of the oven 1.

[0051] In this case, the conveying direction of the second conveyor belt 12 is perpendicular to the direction of the first conveyor belt 11. An outlet is provided on the side of the oven 1, and two second conveyor belts 12 are provided. The conveying directions of the two second conveyor belts 12 are perpendicular to the conveying direction of the first conveyor belt 11.

[0052] Specifically, several rows of fixed columns are vertically arranged inside the oven 1 along the conveying direction of the second conveyor belt 12. Each row of fixed columns includes two symmetrical fixed columns. A rollable roller is provided at the upper end of each fixed column. The roller is driven to rotate electrically. The rollers at the upper ends of several rows of fixed columns form a second conveyor belt 12 for conveying battery trays 10.

[0053] See attached Figure 5 At the same time, a third conveyor belt 13 is provided on one side of the lower end of the oven 1. The transmission direction of the third conveyor belt 13 is the same as that of the second conveyor belt 12 and is connected to one side of the second conveyor belt 12. When the battery trays 10 leave the second conveyor belt 12, they will be transported one by one via the third conveyor belt 13.

[0054] Example 3:

[0055] This embodiment further illustrates the structure of the tray 5 based on the embodiment 1.

[0056] For details, see the attached Figure 6 In this case, two trays 5 are provided, and the two trays 5 are located between two adjacent rows of fixed columns, so that when the tray 5 descends, the battery tray 10 it carries will be placed on the second conveyor belt 12, and when it rises, the battery tray 10 placed on the second conveyor belt 12 will be lifted.

[0057] And because the hot air inside the oven 1 tends to gather above the inside of the box, in order to prevent the heat from being lost, a second door stop 14 that can be raised and lowered vertically is provided on one end face of the bottom of the oven 1. The upper end of the second door stop 14 is connected to an electric push rod for driving the second door stop 14 to move up and down.

[0058] 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 various embodiments of the present invention.
