Description

Technical Field

[0001] The utility model belongs to the technical field of lead-acid battery manufacturing, and in particular relates to a tool for quickly checking the reverse polarity of a battery when it is put into a slot. Background Art

[0002] Lead-acid batteries are widely used in transportation, communications, energy storage and other fields due to their excellent performance, safety and reliability, and low cost. The battery manufacturing process mainly includes plate manufacturing, battery assembly, battery formation and packaging. Most of the faults and defects in the battery manufacturing process are mainly caused by the battery assembly process. There are two main reasons for the reverse polarity of the pole group. The first is that workers check the pole group in many steps during the process of the pole group entering the slot, and it is easy to miss the inspection of whether the pole group entering the slot is reversed; the second is that during the production quality inspection, the pole group is randomly inspected and then entered into the slot for the second time, which is also easy to cause the pole group to be reversed, thus affecting the service life of the battery. Therefore, how to quickly check the reverse polarity of the pole group entering the slot during the battery manufacturing process and ensure the service life of the battery has attracted the attention of various battery manufacturers.

[0003] In order to distinguish between positive and negative poles, there are different numbers of error-proofing grooves on the upper surface of the busbar (one for positive pole and two for negative pole or one for negative pole and two for positive pole). The traditional way to check for reverse polarity when entering the slot is to directly observe the number of error-proofing grooves on the busbar with the naked eye. This method has a slow detection speed and requires careful observation and checking one by one, which is easy to cause visual fatigue. In addition, the workers in the process of entering the pole group into the slot need to check many steps with the naked eye, and there are no reminder measures, so the reverse polarity inspection of the pole group entering the slot may be missed. Summary of the invention

[0004] The purpose of the utility model is to prevent the quality problem of reverse polarity of the pole group entering the slot during the battery manufacturing process, and to provide a tool for quickly checking the reverse polarity of the battery entering the slot. After the pole group is entered into the slot, the tool can be used to quickly observe the anti-error groove on the upper surface of the busbar and compare it with the hollowed-out position on the tool, so that the worker can quickly identify whether the pole group is reversed when the pole group is cast and welded into the slot. Compared with the traditional method of directly checking the reverse polarity with the naked eye, the inspection efficiency is improved. At the same time, the use of the tool can also effectively prevent the worker from missing the reverse polarity inspection due to too many pole group inspection steps, thereby improving the assembly quality of the battery and ensuring that the service life of the battery is not affected.

[0005] The technical solution of the utility model is: a tool for quickly checking the reverse polarity of batteries when they are inserted into slots, characterized in that: it comprises a cover plate; a positioning hole is provided on the cover plate corresponding to the position of the battery pole; a proofreading and observing area with hollowed-out observation holes is provided on the cover plate corresponding to the positions of the anti-error grooves on the surface of the battery bus; a shading plate extending downwardly is provided on the edge of the observation hole parallel to the bus direction; a proofreading plate is connected to the inner edge of the shading plate, and a hollowed-out proofreading hole is provided on the proofreading plate corresponding to the anti-error groove area of ​​the bus.

[0006] The technical solution of the utility model has two circular positioning holes, and a sleeve with an inner diameter matching the outer diameter of the battery pole is arranged on the inner side of the cover plate.

[0007] There are 12 observation holes in the technical solution of the utility model, which are symmetrically distributed in two rows; the number and shape of the proofreading holes on the proofreading plate are consistent with the number and shape of the corresponding busbar table anti-error grooves.

[0008] The cover plate described in the technical solution of the utility model is provided with positioning ribs with the same size as the battery tank partition wall under it.

[0009] The observation hole described in the technical solution of the utility model is rectangular.

[0010] The two sides of the positioning rib described in the technical solution of the utility model are provided with positioning claws.

[0011] The cover plate described in the technical solution of the utility model is provided with a skirt extending downwards around it.

[0012] The proofreading hole described in the technical solution of the utility model is in the shape of a rectangular strip, and its width is 2mm-3mm wider than the width of the busbar error prevention groove.

[0013] The cover plate, the shading plate and the proofreading plate described in the technical solution of the utility model are all made of plastic.

[0014] The height of the shading plate described in the technical solution of the utility model is based on the fit between the calibration plate and the upper surface of the busbar when the cover plate is covered on the battery slot.

[0015] The beneficial effects of the utility model are as follows: after the pole group is put into the slot, if the pole group is not reversed, the busbar error prevention groove can be directly observed from the tooling proofreading hole by using the utility model tooling. If the pole group is reversed, all the error prevention grooves cannot be seen, and it can be quickly determined whether the pole group is reversed, without checking one by one, reducing visual fatigue. At the same time, the increase of the tooling inspection step also greatly reduces the occurrence of missed inspections when directly using the naked eye for inspection.

[0016] The utility model has the advantages of simple structure and operation and fast inspection speed, and can effectively relieve the visual fatigue of workers when inspecting the reverse polarity of pole groups entering the slots, and prevent the reverse polarity defects of the battery assembly, thereby improving the assembly quality of the battery.

[0022] The utility model will now be further described in detail with reference to the accompanying drawings.

[0023] like Figure 1 , Figure 2 As shown, an embodiment of a tool for quickly checking whether the battery is reversed when entering the slot is composed of a cover plate 1 and a positioning hole 2, a proofreading observation area 3, a shading plate 4, a proofreading plate 5, a positioning rib 7 and a positioning claw 8 arranged on the cover plate 1, all of which are made of plastic material and are mainly used for quickly checking whether the battery pole group is in a reversed polarity state when entering the slot.

[0024] The cover plate 1 cooperates with the battery tank body and can cover the upper port of the battery tank body.

[0025] The positioning holes 2 are opened on the cover plate 1 corresponding to the battery pole position. There are two positioning holes 2, which are circular and correspond to the positive and negative poles. A sleeve whose inner diameter matches the outer diameter of the battery pole is provided along the edge of the positioning holes 2 on the inner side of the cover plate 1. The two sleeves are fitted on the two poles to position them and meet the assembly effect.

[0026] The proofreading observation area 3 is arranged on the cover plate 1 corresponding to the position of each error proofing groove on the surface of the battery bus. The proofreading observation area 3 is provided with 12 hollow observation holes, which are rectangular and symmetrically distributed in two rows. The shading plate 4 is arranged to extend downward along the edge of the observation hole parallel to the direction of the bus, and the shading plate 4 is perpendicular to the cover plate 1. The proofreading plate 5 is connected to the inner edge of the shading plate 4, and the proofreading plate 5 is provided with hollow proofreading holes 6 corresponding to the error proofing groove area of ​​the bus. The number and shape of the proofreading holes 6 are consistent with the number and shape of the error proofing grooves on the corresponding bus surface. The proofreading hole 6 is a rectangular strip, and its width is 2mm-3mm wider than the width of the error proofing groove of the bus. The height of the shading plate 4 is based on the fit of the proofreading plate 5 and the upper surface of the bus when the cover plate 1 is covered on the battery slot, and fits with the upper surface of the battery bus when the tooling is used.

[0027] The cover plate 1 is provided with a skirt extending downwardly around its periphery.

[0028] Positioning ribs 7 having the same size as the battery tank partition wall are provided below the cover plate 1 .

[0029] Different numbers of positioning claws 8 are provided on both sides of the positioning rib 7 .

[0030] After the battery pole group is put into the slot, the new tooling is used for inspection. First, the two positioning holes 2 of the cover plate 1 are put on the battery poles, and the cover plate 1 is placed above the battery slot (the original battery cover position). The positioning hole 2 fits with the side of the battery pole, and the positioning rib 7 on the cover plate 1 fits with the partition wall on the battery slot. The positioning claws 8 on the side of the positioning rib 7 assist in positioning. The tooling positioning can be completed in a short time, and there is no need to repeatedly check the position of the tooling. After the tooling is in place, the proofreading plate 5 fits with the upper surface of the bus, and the proofreading hole 6 is just above the anti-error groove on the surface of the bus. The shading plate 4 can gather external light, so that the corresponding state of the anti-error groove and the proofreading hole 6 can be seen more clearly, which relieves visual fatigue.

[0031] There are two states after the battery pole group is put into the slot, namely, the pole group is put into the slot without polarity reversal and the pole group is put into the slot with polarity reversed.

[0032] The state of the pole group entering the slot without reverse polarity is as follows Figure 3 As shown, at this time, the positive and negative poles of the 6 electrode groups of the battery are connected in series, a bus with an anti-error groove is connected in series with the bus with two anti-error grooves, the anti-error grooves of the bus correspond one to one with the positions of the proofreading holes 6 on the tooling of the utility model, and through the proofreading observation area 3, it can be observed that the anti-error grooves on the 12 buses correspond to the proofreading holes 6, so it can be quickly determined that the pole groups are not reversed when entering the slots, the tooling is removed, and the battery can enter the next process.

[0033] The reverse polarity state of the pole group entering the slot is as follows Figure 4 As shown, at this time, not all of the six battery groups are connected in series, and some of the positive and negative poles are connected in series. The busbar error-proofing grooves and the calibration holes 6 on the tooling of the utility model cannot correspond one to one. Only the error-proofing grooves on some of the busbars correspond to the calibration holes 6. Figure 4 , the second and fourth cells cannot see the error-proofing grooves from the proofreading hole 6. At this time, it can be quickly determined that the battery pole group is inserted into the slot with the wrong polarity. The pole group needs to be taken out and adjusted before being re-inserted into the slot. After entering the slot, another inspection is performed. If all the error-proofing grooves can be seen, the next step can be entered.
