Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery processing equipment, in particular to a battery drying production line. BACKGROUND

[0002] During use, the sealing part of the battery will be in 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 batches of oiled batteries are dried to form a protective layer. Ensuring drying quality while improving drying efficiency is important for enterprises to improve battery quality.

[0003] The prior art discloses a Chinese utility model patent with the patent name of lithium ion battery drying tray and drying device, with the patent number CN212006514U, which specifically discloses a tray frame and a plurality of battery support rods arranged between the inner side walls of the tray frame, 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, the size of the heating plate is less than or equal to the internal size of the tray frame of the ion battery drying tray, and the surface of the heating plate has a plurality of grooves corresponding to the battery support rods, the size of the cross section perpendicular to the length direction of the groove is greater than or equal to the size of the cross section perpendicular to the length direction of the battery support rod.

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

[0047] Embodiment 1

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

[0049] Please refer to the accompanying Figures 1-14 , mainly including a frame body 1, a conveying belt 3 and an oven 4, one side of the frame body 1 is provided with a conveying platform 2 for conveying a battery tray 10.

[0050] Please refer to the accompanying Figure 1The conveying platform 2 in the case includes an upper platform and a lower platform arranged vertically and driven in the same direction; the conveying belt 3 is arranged on the frame body 1 and its driving direction is perpendicular to the driving direction of the conveying platform 2.

[0051] The lower platform is provided with a plurality of roller shafts for driving the battery tray 10 vertically, and the upper platform is provided with a grabbing structure for grabbing the battery tray 10 on the roller shaft to the conveying belt 3. The grabbing structure in the case can linearly displace along the driving direction of the conveying platform 2 and also vertically lift up and down. The conveying belt 3 is arranged vertically between the upper platform and the lower platform. The worker places the battery tray 10 on the roller shaft in the lower platform, uses the grabbing structure on the upper platform to clamp the battery tray 10, and moves towards the side of the conveying belt 3. When reaching above the conveying belt 3, the battery tray 10 is placed down. The conveying belt 3 can adopt various modes such as belt and roller shaft, which is not limited here.

[0052] The upper and lower platforms and the grabbing structure are known technologies. In the case, the upper platform includes a truss structure arranged above the lower platform, and a movable support arranged on the truss and linearly movable. The grabbing structure is arranged on the movable support. The moving mode of the movable support is not limited here and can adopt various modes such as screw rod and push rod.

[0053] The grabbing structure includes two symmetrically arranged clamping jaws movable towards each other on the movable support. The movable support is provided with a driving mechanism for linearly moving the clamping jaws, which is not limited here. In the case, the movable support is provided with a sliding rail, and the clamping jaws are slidingly fitted on the sliding rail.

[0054] Referring to the drawings Figure 3 The conveying belt 3 is connected to one side of the conveying platform 2 and used for conveying the battery tray 10 from the conveying platform 2. The battery tray 10 is driven on the conveying belt 3 at intervals, and the conveying belt 3 is intermittently stopped.

[0055] The conveying belt 3 is provided with a stacking unit including two symmetrically arranged transfer clamping jaws 31. The two transfer clamping jaws 31 are movable towards each other and clamp the battery tray 10 on the conveying belt 3. Each transfer clamping jaw 31 can vertically lift along the height direction of the conveyed battery tray 10.

[0056] When the battery tray 10 on the conveying belt 3 moves to the two transfer clamps 31, the two transfer clamps 31 move towards each other and fix on the battery tray 10 at the same time. After the two transfer clamps 31 fix on the battery tray 10, the two transfer clamps 31 clamp the battery tray 10 and then the two transfer clamps 31 rise. At this time, the conveying belt 2 continues to drive. When the next battery tray 10 moves to the two transfer clamps 31 (at this time, it is located below), the two transfer clamps 31 release the fixing and restraint of the current battery tray 10, and the battery tray 10 located above is placed on the battery tray 10 located below to form a stack.

[0057] At this time, the two transfer clamps 31 descend again and fix on the battery tray 10 located below and then the two transfer clamps 31 rise with the two battery trays 10 located above. The conveying belt 2 continues to drive, and the two transfer clamps 31 repeat the above process. When the battery tray 10 held by the two transfer clamps 31 reaches a certain height, the two transfer clamps 31 release the restraint of the battery tray 10 located at the bottom, and the conveying belt 2 is used to move the battery tray 10 to a certain height.

[0058] The conveying belt 3 can be in the form of a belt or a roller, and the specific form is not limited. In this case, two conveying belts 3 are arranged in parallel, and the battery tray 10 is driven on the two conveying belts 3.

[0059] Referring to the drawings Figure 3 The battery tray 10 is driven one by one. In this case, at least one limiting plate 32 vertically movable is arranged on the conveying belt 3. The bottom of the limiting plate 32 is provided with an electric push rod for realizing the up and down movement of the limiting plate 32.

[0060] Embodiment 2

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

[0062] Referring to the drawings Figure 9 The oven 4 is arranged on the other side of the conveying belt 3, and the upper end of the oven 4 is provided with an opening. A group of first conveying belts 41 is arranged on both sides of the opening of the upper end of the oven 4. The driving directions of the two groups of first conveying belts 41 are the same as that of the conveying belt 3, and the distance between the two groups of first conveying belts 41 is adjustable.

[0063] Referring to the drawings Figure 10 Specifically, a fixed clamp 42 is arranged on both sides of the opening of the upper end of the oven 4. The two fixed clamps 42 can move towards each other and fix the battery tray 10 located between the two fixed clamps 42.

[0064] Referring to the drawings Figure 11When the stacked battery trays 10 on the conveying belt 3 move to the first conveying belts 41, the two fixed clamping jaws 42 at this time move towards each other and fix the lowermost battery tray 10, and in this case, a tray 5 vertically lifting along the height direction of the oven 4 is arranged in the oven 4, the moving path of the tray 5 is perpendicular to the conveying belt 3, at this time, the tray 5 is lifted and supported at the lower end of the stacked battery tray 10, at this time, the two fixed clamping jaws 42 are unlocked, and the two first conveying belts 41 move away, the tray 5 starts to descend, and the battery tray 10 on the first conveying belt 41 is transported to the inside of the oven 4.

[0065] In this case, two movable sliders are arranged above the oven 4, and the two groups of first conveying belts 41 are fixed on the two sliders, and the other side of the sliders is provided with an electric driving mechanism for linear pushing of objects, which is a known technology and is not limited here, and a lead screw or an electric push rod can be used.

[0066] Embodiment 3:

[0067] This embodiment is based on embodiment 1, and further describes the specific structure of the stopper.

[0068] Referring to the accompanying Figure 7 The conveying belt 3 is provided with a stopper for preventing the battery tray 10 from backtracking on the conveying belt 3, and the stopper is located on the transmission path of the battery tray 10; wherein the stopper comprises a baffle 33 elastically hinged in the middle of the conveying belt 3, and the side end face of the baffle 33 away from the oven 4 is a slope, and the slope is located on the transmission path of the battery tray 10.

[0069] When the battery tray 10 is transmitted on the conveying belt 3, the battery tray 10 will be in contact with the slope on the baffle 33 and make the baffle 33 rotate by a certain angle, and when the battery tray 10 has a certain backtracking tendency, the battery tray 10 at this time 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 at this time is parallel to the side end face of the battery tray 10, so that the battery tray 10 will be in contact with the back of the baffle 33 once backtracking, and at this time, the baffle 33 is difficult to rotate, so that the backtracking of the battery tray 10 can be limited.

[0070] It is worth mentioning that the baffle 33 in this case can also be arranged as a one-way rotating mechanism, and the elastic hinged structure and the one-way rotating structure are both known common sense, which is not limited here, and is not shown in the drawings.

[0071] In the case, the distance between the baffle 33 and the oven 4 can be adjusted according to actual needs, the bottom of the baffle 33 is provided with a sliding rail structure, which can linearly slide on the conveying belt 3 and can be locked, and the specific locking method is a known technology, which will not be repeated here, and an electric push rod structure can be arranged on the rear side of the baffle 33 to achieve it.

[0072] Referring to the drawings Figure 9 It should be noted that each group of first conveying belts 41 is provided with a guide plate 411 at one end facing the conveying belt 3, and the guide plates 411 on the two first conveying belts 41 are in a figure-eight structure with the wide side facing the side of the conveying belt 3. Since the battery tray 10 may deviate from the initial displacement trajectory during transmission, it may be stuck between the two groups of first conveying belts 41, and after passing through the two figure-eight guide plates 411, it to some extent plays a correcting function, facilitating the smooth entry of the battery tray 10 above the two first conveying belts 41.

[0073] Referring to the drawings Figure 11 Further, a second conveying belt 43 is arranged inside the oven 4 for sending out the battery tray 10 inside the oven 4; wherein the second conveying belt 43 includes a plurality of columns of fixed columns 431 arranged along the conveying direction of the second conveying belt 43, the fixed columns 431 are vertically arranged inside the oven 4 and the upper ends thereof are provided with rollers 432, and each column of fixed columns 431 includes two symmetrical fixed columns 431.

[0074] And the tray 5 in the case includes two parallel tray arms, the tray arms are located between the adjacent two columns of fixed columns 431, so that the tray 5 can be moved to the lower side of the roller 432, that is, the battery tray 10 held by the tray 5 is placed on the upper side of the roller 432, and the rotation of the roller 432 realizes the purpose of moving the battery tray 10 out of the oven 4.

[0075] Referring to the drawings Figure 2 In the case, the left and right sides of the side end face of the battery tray 10 are respectively provided with a bayonet 101, and a fixing port 102 cooperating with the transfer clamping jaw 31 and the fixed clamping jaw 42 is arranged in the middle of the bayonet 101.

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

[0077] And the other side of the oven 4 is provided with a transmission mechanism cooperating with the second conveying belt 43 and continuing to convey the battery tray 10 out of the oven 4, which is a known technology and will not be repeated here.

[0078] The above examples are only used to illustrate the technical solutions of the present application, but not to limit the present application; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some technical features can be replaced by equivalent features; and 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 application.
