Description

Technical Field

[0001] The utility model belongs to the technical field of lead-acid batteries, and in particular relates to a polar plate feeding device for an encapsulating machine. Background Art

[0002] The pole group encapsulation process is the process of combining the positive plate, negative plate and separator of the lead-acid battery into a pole group.

[0003] The plate encapsulation machine is an automated equipment for high-efficiency, high-quality, low-loss and large-scale production that realizes the automation of battery production equipment. The plate feeding system transports the plates one by one to the designated position at the front end of the encapsulation machine to ensure the smooth and continuous encapsulation of the plates. It is an important part of the battery plate encapsulation process and has an important impact on the production efficiency and the quality of battery products. When the positive and negative plates enter the encapsulation machine, the plate ears need to be in opposite directions, so that the encapsulated positive and negative plate ears will be arranged on the left and right sides of the pole group. The cast welding process welds all the positive plate ears of the same pole group into the positive bus bar, and all the negative plate ears into the negative bus bar. If the plate ears of the positive and negative plates are in the same direction when they enter the encapsulation machine, the encapsulated positive and negative plate ears are located on the same side of the pole group. After cast welding, the positive and negative plates are welded into the same bus bar, and the other polarity bus bar is missing pieces, which seriously affects the battery performance. In addition, some plates with super-high height during cast welding will affect the welding effect and battery life. During cast welding, the bottom of the pole group is in the same plane, and the plate ears of the extra-high plates will be higher than the conventional plates. This part of the plate ears is inserted too deeply into the bus, resulting in insufficient remaining thickness of the bus, reduced strength of the bus, and affecting the battery life.

[0004] However, the current main solutions for loading plates are as follows: one is to use belts or tracks to achieve movement. The other is to use vacuum disc adsorption and realize position conversion through circular transmission. However, none of the above solutions effectively monitor the reverse and super-height of the plates. At present, the height difference and reverse situation of the whole stack of plates are visually checked by manual sorting of the plates to prevent the reverse of the pole ears and exclude the plates with super-high height. However, each stack of poles needs to be sorted manually for about 20 seconds, which is labor-intensive and easy to miss during visual inspection. Summary of the invention

[0005] The purpose of the utility model is to solve the deficiencies of the above-mentioned prior art, thereby providing a plate loading device for an encapsulating machine, which avoids missed inspections and improves quality stability; at the same time, it reduces the number of personnel operations and reduces labor intensity.

[0006] The technical solution of the utility model is: a plate feeding device for an encapsulating machine, arranged at the feeding port end of the encapsulating machine, comprising:

[0007] A plate conveying device for conveying plates, the plate conveying device comprising a lower crawler, a left crawler and a right crawler, the said;

[0008] An error-proofing device is provided near the pole lug to prevent the pole lug direction and the pole plate from being too high;

[0009] The error prevention device comprises a fixing plate standing on one side of the plate conveying device, wherein the fixing plate has two bolt mounting holes arranged side by side, the upper and lower bolt mounting holes on which the limit bolts can be mounted, the upper and lower bolt mounting holes on the plate respectively correspond to the height positions of the tabs of the positive and negative plates, and the limit bolt is mounted in one of the bolt mounting holes;

[0010] and an alignment plate disposed on an opposite side of the error proofing device.

[0011] After the positive and negative electrode plates are placed on the lower track, the positive and negative electrode tabs are horizontally oriented toward the upper and lower ends of the same side.

[0012] The left crawler track and the right crawler track are symmetrical and located between the bolt mounting holes.

[0013] When the limiting bolt is screwed into the bolt mounting hole, the vertical distance between the top of the limiting bolt and the upper frame of the plate is 1~2mm.

[0014] Compared with the prior art, the utility model realizes automated inspection, avoids missed inspections and improves quality stability; at the same time, it reduces human operations and reduces labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] like Figure 1 , Figure 2As shown, a plate conveying device for conveying a plate 6 is composed of a lower crawler 40, a left crawler 41 and a right crawler 42. The lower crawler 40 is arranged below the plate 6, and the left crawler 41 and the right crawler 42 are symmetrically arranged on the left and right sides of the plate. The front end of the lower crawler 40 protrudes from the front ends of the left crawler 41 and the right crawler 42. The error-proofing device and the alignment plate 7 are respectively arranged on both sides of the front end of the lower crawler 40. The error-proofing device includes a fixed plate 1, which is vertically erected on a bottom plate 8 on one side of the lower crawler 40. The bottom plate 8 and the alignment plate 7 can be fixed on a frame (not shown in the figure), and the fixed plate 1 is fixed to the upper and lower A bolt mounting hole 3 is opened at each end, and the two bolt mounting holes 3 are arranged side by side and used to install the limit bolt 2, and the limit bolt 2 is installed in one of the bolt mounting holes 3; the alignment plate 7 is arranged on the opposite side of the anti-error device, and after the plate is placed at the front end of the lower crawler 40, the bottom is close to the alignment plate 7, the pole ear faces the side of the anti-error device, and it is ensured that the positive pole ear and the negative pole ear are placed in an up-down misaligned manner, and the upper and lower bolt mounting holes 3 correspond to the height positions of the pole ears of the positive and negative plates respectively, and when the limit bolt 2 is screwed into the bolt mounting hole 3 above the fixing plate 1, the plate ear of the plate can only pass from below. When the limit bolt 2 is screwed into the bolt mounting hole 3 below the fixing plate, the plate ear of the plate can only pass from above, realizing the anti-error of the plate ear direction. When the limit bolt 2 is screwed into the bolt mounting hole 3, the vertical distance between the top of the limit bolt 2 and the upper frame of the plate is 1~2mm. If the plate is too high, it will not be allowed to pass, effectively preventing the high-height plate from passing, and realizing the function of screening the high-height plate.
