Description

Technical Field

[0001] The invention belongs to the technical field of battery processing equipment, and in particular relates to a battery internal formation device with a full-automatic cooling system. Background Art

[0002] Formation is the process of battery plates from upgraded plates to mature plates before leaving the factory, and this process is usually achieved by charging. Battery formation methods are divided into internal formation and external formation. External formation is charging and forming outside the battery, but a large amount of acid gas is released, which seriously pollutes the environment and has been banned. Internal formation is to assemble the plates inside the battery for charging and forming, which reduces air pollution but challenges battery quality.

[0003] When existing batteries are formed, since the positive and negative electrodes of the batteries need to be connected to the charging lines of the charging pile, this work is mostly done manually. In this process, in order to improve the efficiency of battery formation, multiple groups of batteries are generally placed on a tray, then bundled and fixed, and then the positive and negative electrodes of the multiple batteries on the tray are connected in series. When the batteries on the tray are connected in series, a forklift is used to transport the battery group to the charging pile for formation. Since the tray itself does not have a heat dissipation function, and during the battery formation process, the battery will generate heat due to charging, and the batteries are bundled and fixed together, it is easy to cause the battery temperature to be too high, and high temperature is easy to cause battery dendrite short circuit and dissolution of plate additives, resulting in a decrease in battery performance and an increase in defective products.

[0004] In order to solve the above problems, a Chinese patent with the announcement number CN219371108U proposed an automatic cooling system for lead-acid batteries, "including a battery cooling water tank, characterized in that the battery cooling water tank is divided along its length to form a number of independent cooling water pools, a temperature detector is provided in the cooling water pool, and each cooling water pool is provided with a water inlet and a water outlet." The invention realizes the cooling operation of the battery in the cooling water tank through heat exchange between the cooling water tank and the cooling water tower, and the sewage treatment equipment is added during the cooling process, so as to realize the recycling of sewage while cooling. Although the invention solves the problem of battery heating to a certain extent, it still has the following shortcomings in actual operation:

[0005] 1. The cooling system in the above invention is large in size and inconvenient to move;

[0006] Second, there is also inconvenience when placing the battery into the cooling water tank;

[0007] 3. The cooling water tank cannot cool batteries of different sizes well.

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0034] The present invention provides Figures 1 to 8A battery internal formation device with a fully automatic cooling system is shown, comprising a charging pile 1, wherein the front and rear sides of the charging pile 1 are connected to a plurality of charging cables 2, the front and rear sides of the charging pile 1 are horizontally provided with a U-shaped support frame 3, and the opening direction of the support frame 3 is opposite to the charging pile 1, a battery storage box 4 is provided inside the support frame 3, both sides of the battery storage box 4 are fixedly connected with support bars 5, the support frame 3 is supported on the bottom of the support bar 5, a plurality of cooling plates 6 are arranged in parallel in the battery storage box 4, the front and rear sides and the bottom of the cooling plate 6 are respectively fixedly connected to the front and rear sides and the inner wall of the bottom of the battery storage box 4, a cold water trough 7 is provided on the top of the cooling plate 6 and both sides of the top of the battery storage box 4, and the front and rear sides of the plurality of cold water troughs 7 are alternately connected to form a cold water channel located on both sides The two cooling water tanks are connected to a water inlet pipe 8 and a water outlet pipe 9 on the side away from the charging pile 1, and the height of the water inlet pipe 8 is lower than the height of the water outlet pipe 9. The tops of the multiple cold water tanks 7 are detachably installed with the same sealing cover 10, and the shape of the sealing cover 10 matches the shape of the cold water channel. Multiple battery compartments are arranged between the cooling plate 6 and the side wall of the battery storage box 4 and between two adjacent cooling plates 6, and a vertical partition 11 is arranged between two adjacent battery compartments, and the top of the partition 11 is flush with the top of the sealing cover 10, and the partition 11 is fixedly connected to the inner wall of the battery compartment, and a storage assembly 12 is arranged in the battery compartment. A heat dissipation assembly 13 is installed on the side of the battery storage box 4 close to the charging pile 1, and the bottom of the battery storage box 4 is vertically fixedly connected to a first support leg 14 near the four corners;

[0035] The storage assembly 12 includes a horizontally arranged storage plate 121, and the storage plate 121 is of a hollow design. A support rod 122 is vertically fixedly connected to the center of the bottom of the storage plate 121. A connecting rod 123 is arranged at the bottom end of the support rod 122. The bottom end of the connecting rod 123 vertically slides through and is inserted into the bottom inner wall of the battery compartment. A socket is provided at the top of the connecting rod 123. The bottom end of the support rod 122 is slidably inserted into the socket. A support spring 124 is fixedly connected between the bottom end of the support rod 122 and the bottom inner wall of the socket. The support spring 124 is provided with a spring 124. A limiting rod 125 is arranged on the side, and the limiting rod 125 is vertically fixedly connected to the inner wall of the bottom of the jack. The four corner positions of the bottom of the storage plate 121 are vertically fixedly connected with positioning rods 126. The bottom ends of the plurality of connecting rods 123 are fixedly connected with the same supporting plate 127. The bottom of the supporting plate 127 near the four corners is vertically fixedly connected with a second supporting leg 128. In the initial state, the distance from the top of the storage plate 121 to the bottom of the second supporting leg 128 is equal to the distance from the top of the sealing cover 10 to the bottom of the first supporting leg 14, and the distance is less than the height of the support frame 3;

[0036] When the battery 15 is internalized, the battery storage box 4 is first placed on the ground under the support of the first support leg 14. As the first support leg 14 contacts the ground, the second support leg 128 can also keep in contact with the ground. At this time, the top of the support plate 127 is kept in close contact with the bottom of the battery storage box 4, and the storage plate 121 is also kept flush with the top of the sealing cover 10 under the support of the support spring 124, so that the battery 15 can be easily pushed along the top of the battery storage box 4. Then, the battery 15 to be internalized is placed on the storage plate 121 in the multiple battery compartments in turn. As the battery 15 is placed on the storage plate The top of the plate 121 is moved downward by the support rod 122 under the action of pressure. During this process, the support spring 124 is gradually compressed, and the support rod 122 gradually approaches the limit rod 125. When the support rod 122 contacts the limit rod 125, the plate 121 stops moving, and the bottom of the battery 15 partially enters the battery compartment, thereby preventing the battery 15 from moving through the restriction effect of the battery compartment on the battery 15. When all the batteries 15 are placed in the battery compartment, since most of the batteries 15 are located outside the battery compartment, the batteries 15 in each battery compartment can be conveniently connected in series.

[0037] After the battery 15 is connected in series, a forklift is used to move the battery storage box 4 to the charging pile 1. When the forklift is used to move the battery storage box 4, the fork of the forklift is inserted into the bottom of the pallet 127, and then the pallet 127 is lifted upward to realize the lifting and transfer operation of the battery storage box 4. When the battery storage box 4 is moved to the charging pile 1, the forklift is used to put the battery storage box 4 from the opening of the support frame 3 into the inner side of the support frame 3, and the support bar 5 is located at the top of the support frame 3. After the support frame 3 realizes the support operation of the battery storage box 4 through the support bar 5, as the fork of the forklift moves downward , the support plate 127 can move downward under the pressure of the battery 15 on the connecting rod 123. During this process, the battery 15 can move downward and enter the battery compartment. When the positioning rod 126 contacts the bottom of the battery compartment, the storage plate 121 stops moving. At this time, the first supporting leg 14 and the second supporting leg 128 are both in a suspended state, and the battery 15, except for its top part, can completely enter the battery compartment and keep in contact with the cooling plates 6 on both sides. Then, the series-connected battery 15 is connected to the charging line 2 of the charging pile 1, and then the water inlet pipe 8 and the water outlet pipe 9 of the battery storage box 4 are connected to the external water channel to form a loop;

[0038] After the external water circuit is connected, the charging pile 1 is started to perform internalization operation on the battery 15. At the same time, the heat dissipation component 13 and the external water circuit are started to inject cooling water into the battery storage box 4. As the cooling water continuously enters the battery storage box 4 through the water inlet pipe 8 and flows out from the water outlet pipe 9, the cooling water can take out the heat transferred from the battery 15 to the cooling water through the cooling plate 6, thereby cooperating with the heat dissipation effect of the heat dissipation component 13 on the battery 15, improving the heat dissipation effect of the battery 15, thereby avoiding battery dendrite short circuit and dissolution of plate additives, and ensuring the qualified rate and performance of the battery 15;

[0039] In addition, compared with the prior art, the storage assembly 12 in the battery storage box 4 of the present invention can facilitate the storage and retrieval of the battery 15 during the process of placing the battery 15 in and taking it out of the battery compartment. At the same time, the battery storage box 4 in the present invention is smaller in size than the cooling system composed of the cooling water tank and the cooling water tower lamp structure in the comparative document, and is also more convenient to store and release. It can also be moved according to needs, which is more flexible.

[0040] like Figure 2 and Figure 5 As shown, the heat dissipation assembly 13 includes a long strip heat dissipation fan 131, and the heat dissipation fan 131 is installed on the side of the battery storage box 4 close to the charging pile 1. A plurality of flat heat dissipation pipes 132 are inserted through the side of the battery storage box 4 close to the charging pile 1. The plurality of heat dissipation pipes 132 are inserted into the spaces on both sides of the plurality of cooling plates 6 one by one, and the plurality of heat dissipation pipes 132 are directly opposite to the heat dissipation fan 131, and a heat dissipation hole 133 is opened through the position of the partition 11 directly opposite to the heat dissipation pipe 132;

[0041] During the internalization of the battery 15, as the cooling fan 131 is started, the wind generated by the cooling fan 131 can be blown into the space on both sides of the cooling plate 6 through the cooling pipe 132, and then the external airflow can enter each battery compartment through the multiple cooling holes 133 in sequence. Since the storage plate 121 is hollow, the airflow can drive the heat in the battery compartment to flow upward out of the battery compartment through the gap between the battery 15 and the inner wall of the battery compartment, thereby cooperating with the cooling water to improve the heat dissipation effect of the battery 15;

[0042] In addition, when the airflow flows upward through the gap in the side wall of the battery compartment, the airflow can also cool the inner wall of the battery compartment, so that part of the heat transferred to the cooling water through the cooling plate 6 can be carried along with the airflow.

[0043] like Figures 3 to 6As shown, a battery 15 is arranged in the battery compartment, and the width of the battery 15 matches the width of the battery compartment, the battery 15 is located on the top of the storage plate 121, and slide grooves are provided on the inner walls on both sides of the battery compartment, and the groove wall on the side opposite to the battery 15 is inclined from top to bottom toward the direction close to the battery 15, and a metal heat conducting plate 16 is slidably installed in the slide groove, and the side of the metal heat conducting plate 16 close to the battery 15 is a vertical plane, and the thickness of the metal heat conducting plate 16 gradually becomes thinner from top to bottom, and the side of the metal heat conducting plate 16 away from the battery 15 is parallel to the inner wall of the slide groove and connected together by sliding, and the bottom surface of the metal heat conducting plate 16 is designed as an inclined surface, and the upper edge of the bottom surface of the metal heat conducting plate 16 is close to the metal heat conducting plate 16. The side near the battery 15 is smoothly connected together, the width of the top of the metal heat conductive plate 16 matches the width of the top of the slide slot, and when the metal heat conductive plate 16 is completely received in the slide slot, the top of the metal heat conductive plate 16 is flush with the top of the partition 11, and when the positioning rod 126 contacts the bottom of the battery compartment, the metal heat conductive plate 16 is located on the top of the storage plate 121, and the side of the metal heat conductive plate 16 close to the battery 15 is provided with a plurality of vertical heat dissipation grooves 18, and the top and bottom ends of the heat dissipation grooves 18 are respectively connected to the top surface and the bottom inclined surface of the metal heat conductive plate 16, the size of the top surface of the storage plate 121 matches the size of the battery compartment opening, and the sum of the gravity of the storage plate 121 and the two metal heat conductive plates 16 is less than the minimum elastic force of the support spring 124;

[0044] By providing the metal heat-conducting plate 16, when the battery storage box 4 is placed on the ground, the second supporting leg 128 can keep in contact with the ground, and the storage plate 121 can keep flush with the top of the sealing cover 10 under the support of the supporting plate 127 on the connecting rod 123, and at this time, the metal heat-conducting plates 16 on both sides of the battery compartment can keep flush with the top of the sealing cover 10 under the restriction of the storage plate 121, as the battery 15 is placed on the top of the storage plate 121, the battery 15 can press the storage plate 121 downward, so that the support spring 124 can be compressed by the support rod 122, and when the support rod 122 contacts the limit rod 125, the storage plate 121 stops moving, and in this process, the storage plate 121 can move downward along the metal heat-conducting plates 16 on both sides of the battery compartment, and the metal heat-conducting plates 16 can keep still;

[0045] As the battery storage box 4 is placed on the support frame 3 by a forklift, as the forklift gradually moves away, the support plate 127 can move downward. During this process, the battery 15 and the storage plate 121 can move further downward until the positioning rod 126 contacts the bottom of the battery compartment. As the storage plate 121 moves downward, when the top of the storage plate 121 is lower than the bottom of the metal heat conductive plate 16, the metal heat conductive plate 16 can move downward along the inclined slide groove under the action of gravity. During this process, the metal heat conductive plate 16 can fit together with the battery 15. At this time, the heat generated by the battery 15 can be transferred to the cooling plate 6 through the metal heat conductive plate 16, so that the battery 15 can better transfer the heat to the cooling water, thereby improving the cooling effect of the cold water on the battery 15.

[0046] Furthermore, since the metal heat-conducting plate 16 has a certain thickness, as the metal heat-conducting plate 16 moves to different distances from the battery 15, the metal heat-conducting plate 16 can be suitable for heat-conducting operations of batteries 15 of different sizes;

[0047] In addition, since there are heat dissipation slots 18 on the metal heat conductive plate 16, when the airflow drives the heat in the battery compartment to flow upward, the heat dissipation slots 18 can increase the heat flow channel, thereby improving the heat dissipation efficiency;

[0048] After the battery 15 completes the internal formation operation, as the battery storage box 4 is put back on the ground, the second supporting leg 128 can first contact the ground and push the support plate 127 upward, and as the support plate 127 moves upward, the storage plate 121 can move upward under the supporting force of the support plate 127 on the connecting rod 123, and when the storage plate 121 contacts the metal heat conductive plate 16, the metal heat conductive plate 16 can move obliquely upward along the slide groove under the thrust of the storage plate 121 on its bottom inclined surface, and as the metal heat conductive plate 16 continues to move upward, when the metal heat conductive plate 16 completely enters the slide groove, the metal heat conductive plate 16 is no longer subject to the upward thrust of the storage plate 121, and the storage plate 121 can continue to move upward against the metal heat conductive plate 16.

[0049] like Figures 4 to 8 As shown, a return coil 17 is provided at the bottom of the storage plate 121, and the height of the return coil 17 is less than the height of the positioning rod 126, and both ends of the return coil 17 are plugged into the same cold water tank 7, and the two ends of the return coil 17 are distributed up and down, and the opening direction of the return coil 17 at the top is directly opposite to the direction of the water flow in the cold water tank 7, and the opening direction of the return coil 17 at the bottom is opposite to the direction of the water flow in the cold water tank 7;

[0050] By providing the reflux coil 17, the cooling water in the cold water tank 7 can absorb heat during the process of cooling the battery 15, and because the upper part of the cooling plate 6 is opposite to the battery 15, the water temperature in the upper part of the cold water tank 7 is relatively high. At this time, as the cooling water flows along the cold water channel, the hotter cooling water in the upper part of the cold water tank 7 can enter the reflux coil 17 through the top inlet of the reflux coil 17, and then the wind generated by the heat dissipation fan 131 blows on the reflux coil 17 through the heat dissipation holes 133, so that the hot water in the reflux coil 17 can be dissipated and cooled, thereby improving the cooling effect of the cooling water on the battery 15. Subsequently, the cooled cooling water can flow back to the cold water tank 7 through the bottom outlet of the reflux coil 17, so as to promote the temperature balance between the cooling water in the upper part and the cooling water in the lower part of the cold water tank 7;

[0051] In addition, due to the existence of the reflux coil 17, the retention time of the cooling water in the cold water tank 7 is also prolonged, and the heat generated by the battery 15 can be more fully absorbed by the cooling water.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
