Description

Technical Field

[0001] The utility model relates to the technical field of dry cell carbon rod loading equipment, in particular to a carbon rod pressure-compensating bow rod. Background Art

[0002] At present, in the field of mechanized battery processing in China, when loading carbon rods into zinc shells filled with carbon powder, most of them are loaded horizontally. This loading method, because the zinc shell is placed horizontally, is prone to cause the carbon powder to tilt due to the position of the zinc shell. After the carbon rod is inserted, the density of carbon powder around the axis of the carbon rod is uneven, which affects the overall quality of the battery.

[0003] At the same time, there are also methods of installing carbon rods by loading in the prior art, such as Chinese patent CN206134822U, which discloses a carbon rod installation machine, including a frame, a carbon rod feeding device and a carbon rod insertion device. The carbon rod feeding device consists of a carbon rod bucket, a horizontal carbon rod distribution wheel, a carbon rod lead-out groove, a carbon rod steering groove, a vertical carbon rod conveying groove and a vertical carbon rod distribution wheel. The carbon rod bucket corresponds to the horizontal carbon rod distribution wheel, the horizontal carbon rod distribution wheel corresponds to the carbon rod lead-out groove, the carbon rod lead-out groove corresponds to the carbon rod steering groove, the carbon rod steering groove corresponds to the vertical carbon rod conveying groove, and the vertical carbon rod conveying groove corresponds to the vertical carbon rod distribution wheel. The carbon rod insertion device consists of a fixed vertical shaft, an installation turntable, a battery chuck, a carbon rod chuck, a slide shaft disk, a carbon rod insertion slide shaft, and a carbon rod insertion track wheel. The number of battery chucks, carbon rod chuck teeth and carbon rod insertion slide shafts is the same and corresponding. The vertical carbon rod distribution wheel corresponds to the carbon rod chuck. The carbon rod installation machine can continuously transport the carbon rods to the punching and inserting installation position, and complete the precise positioning and installation of the carbon rods into the battery products.

[0004] At present, when the carbon rod is loaded by vertical loading, the carbon powder in the zinc shell will be deformed due to the insertion of the carbon rod, so the carbon rod needs to be pressed to flatten the carbon powder.

[0005] In some battery assembly processes, before the carbon rod is inserted, a powder pad is placed on the surface of the carbon powder to avoid a large amount of dust. In this way, when the carbon powder is pressed, the carbon powder deformed on the surface is easy to fly out from the edge of the powder pad to the top of the powder pad. If there is carbon powder on the powder pad, it will affect the quality of the battery. However, the existing carbon powder pressing device cannot realize the cleaning of the top surface of the powder pad after pressing the carbon powder inserted into the carbon rod. Utility Model Content

[0006] The utility model aims to provide a carbon rod pressure-compensating bow rod to solve the problem that the existing carbon rod pressing equipment cannot clean and discharge the surface of carbon powder while compensating the carbon powder.

[0007] In order to solve the above problems, the utility model adopts the following technical means:

[0008] A carbon rod pressure-compensating bow rod comprises a driving part and a pressure-compensating part;

[0009] The pressing end of the pressure replenishing part is constructed with a carbon rod passing groove and a horizontally penetrating powder discharge channel, the carbon rod passing groove is connected to the powder discharge channel, and the bottom surface of the powder discharge channel serves as a carbon powder collecting part.

[0010] Preferably, the driving part comprises a pressure-compensating outer bow sleeve, and the pressure-compensating part comprises a pressure-compensating inner bow rod;

[0011] The pressure-compensating inner bow rod includes a pressure-compensating positioning block arranged in the pressure-compensating outer bow sleeve, and a carbon rod pressure-compensating head extending out of the pressure-compensating outer bow sleeve is installed at the bottom end of the pressure-compensating positioning block. The carbon rod passes through a groove and is coaxially arranged at the bottom end of the carbon rod pressure-compensating head, and the powder discharge channel is arranged at the lower section of the carbon rod pressure-compensating head.

[0012] Furthermore, a second pressure-maintaining chamber is provided in the pressure-compensating outer bow sleeve, the pressure-compensating positioning block is slidably provided in the second pressure-maintaining chamber, and the second pressure-maintaining chamber is connected to an external pressure supply system through a pipeline channel provided in the pressure-compensating outer bow sleeve.

[0013] Furthermore, the second pressure-maintaining chamber and the pipeline channel are sealed and filled with hydraulic oil, and the external pressure supply system is an oil supply system.

[0014] Furthermore, the outer wall of the pressure-compensating positioning block is provided with a sealing rubber sleeve.

[0015] Furthermore, a seventh needle roller bearing is installed on the top side wall of the driving part.

[0016] Furthermore, the liquid inlet end of the pipeline channel is arranged on the side wall of the pressure-compensating outer bow sleeve.

After the pressure-replenishing is completed, the carbon powder in the powder discharge channel can move upward with the pressure-replenishing part and exit from the zinc shell, thereby realizing the purpose of cleaning the carbon powder leaked from the edge of the powder pad while performing the pressure-replenishing.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Please refer to Figure 1 and Figure 2 As shown, a carbon rod pressure-compensating bow rod comprises a driving part 401 and a pressure-compensating part 402;

[0029] The pressing end of the pressure replenishing part 402 is constructed with a carbon rod passing groove 403 and a horizontally penetrating powder discharge channel 404. The carbon rod passing groove 403 is connected to the powder discharge channel 404, and the bottom surface of the powder discharge channel 404 serves as a carbon powder collecting part.

[0030] In this way, the driving part 401 is linked with the external device to control the up and down movement of the pressure-replenishing part 402, so that the pressure-replenishing part 402 acts on the top surface of the carbon powder in the zinc shell, and the pressure-replenishing part 402 is used to press the carbon powder loaded with the carbon rod, so that the carbon powder is compacted. At the same time, when the pressure-replenishing is performed, the carbon rod enters the carbon rod through the groove 403, so that the end of the pressure-replenishing part 402 can contact the top surface of the carbon powder, thereby realizing the compaction of the carbon powder. At the same time, during the compaction process, the carbon powder leaked from the edge of the powder pad can be clamped between the outer wall of the pressure-replenishing part 402 and the inner wall of the zinc shell, and as the pressure-replenishing part 402 moves downward, the carbon powder leaked from the edge of the powder pad can enter the powder discharge channel 404 for collection. After the pressure-replenishing is completed, the carbon powder in the powder discharge channel 404 can move upward with the pressure-replenishing part 402 and exit from the zinc shell, thereby realizing the purpose of cleaning the carbon powder leaked from the edge of the powder pad while the pressure-replenishing is performed on the carbon powder.

[0031] Specifically, the aforementioned driving part 401 includes a pressure-compensating outer bow sleeve 405, and the aforementioned pressure-compensating part 402 includes a pressure-compensating inner bow rod.

[0032] Among them, the pressure-compensating inner bow rod includes a pressure-compensating positioning block 406 arranged in the pressure-compensating outer bow sleeve 405, and the bottom end of the pressure-compensating positioning block 406 is installed with a carbon rod pressure-compensating head 407 extending out of the pressure-compensating outer bow sleeve 405, the carbon rod passes through the groove 403 and is coaxially arranged at the bottom end of the carbon rod pressure-compensating head 407, and the powder discharge channel 404 is arranged at the lower section of the carbon rod pressure-compensating head 407.

[0033] Therefore, the aforementioned carbon rod pressure supplementing head 407 is a component for supplementing pressure on carbon powder. The arrangement of the carbon rod passing through the slot 403 can, on the one hand, prevent the carbon rod from affecting the descent of the carbon rod pressure supplementing head 407, and, on the other hand, prevent the carbon rod from tilting during the process of supplementing pressure on carbon powder.

[0034] Furthermore, in order to avoid reducing the amount of carbon powder leaking from the edge of the powder pad during the pressure replenishing process, a second pressure maintaining chamber 408 is provided in the pressure replenishing outer bow sleeve 405, and the pressure replenishing positioning block 406 is slidably provided in the second pressure maintaining chamber 408. The second pressure maintaining chamber 408 is connected to the external pressure supply system through a pipeline channel 409 provided in the pressure replenishing outer bow sleeve 405.

[0035] In this way, the pressure in the second pressure-maintaining chamber 408 compresses the pressure-replenishing positioning block 406, so that the carbon rod pressure-replenishing head 407 can apply pressure to the carbon powder. Two-stage pressure replenishment is used to reduce the amount of carbon powder leaking from the edge of the powder pad. The first stage of pressure replenishment is the pressure in the second pressure-maintaining chamber 408 that is transferred to the surface of the carbon powder through the carbon rod pressure-replenishing head 407. As the pressure-replenishing outer bow sleeve 405 continues to move downward, the pressure-replenishing positioning block 406 moves upward under the reaction force of the carbon powder, so that the second pressure-maintaining chamber 408 gradually decreases, so that the pressure-maintaining medium in the second pressure-maintaining chamber 408 is compressed in volume, so that the pressure medium in the second pressure-maintaining chamber 408 is transferred to the carbon rod pressure-replenishing head 407. The pressure will gradually increase, so that after the second pressure-maintaining chamber 408 is compressed, the second stage of pressure replenishment is performed, and the carbon powder is finally compacted by the second stage of pressure replenishment after the first stage of pressure replenishment. In this way, the amount of carbon powder leaking from the edge of the powder pad during the pressure replenishment process of the carbon powder with the carbon rod inserted can be effectively reduced.

[0036] Furthermore, the second pressure-maintaining chamber 408 and the pipeline channel 409 are sealed and filled with hydraulic oil, and the external pressure supply system is an oil supply system.

[0037] In this way, the pressure medium in the second pressure-maintaining chamber 408 is hydraulic oil. By utilizing the oil supply system, the force of the first stage and second stage pressure replenishment can be adjusted by adjusting the oil pressure and the type of hydraulic oil, so that they can adapt to the best pressing state.

[0038] Furthermore, a sealing rubber sleeve 410 is provided on the outer wall of the pressure-compensating positioning block 406 .

[0039] The sealing rubber sleeve 410 is then used to ensure the pressure in the second pressure-maintaining chamber 408 .

[0040] In addition, a seventh needle bearing 411 is installed on the top side wall of the driving part 401 .

[0041] Specifically, the seventh needle roller bearing 411 is installed on the top side wall of the pressure-compensating outer bow sleeve 405, so that the seventh needle roller bearing 411 can follow the upward or downward tilt of the track in the corresponding track, that is, the pressure-compensating outer bow sleeve 405 can be tilted upward or downward.

[0042] Furthermore, the liquid inlet end of the pipeline channel 409 is arranged on the side wall of the pressure-compensating outer bow sleeve 405.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
