Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to a drying device for cylindrical battery caps. Background Technology

[0002] Cylindrical battery caps, or simply "caps," are the top sealing components of cylindrical secondary batteries and a key structure connecting the battery to external circuits. During the production of cylindrical battery caps, oil stains are generated. After cleaning, a drying device is needed to dry them to remove residual moisture and prevent it from negatively affecting battery performance, safety, and lifespan.

[0003] For example, a battery cap drying device disclosed in patent number CN214426386U involves placing the battery cap on top of a conveyor belt, turning on the power of a servo motor to drive the conveyor belt to rotate, and turning on the power of a blower to blow air onto the first ventilation pipe, thereby drying the cap. However, when the conveyor belt transports cylindrical battery caps, the caps are mostly stacked in a disordered state, and the lower caps are blocked by the upper caps, resulting in incomplete drying. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a cylindrical battery cap drying device to solve the problem of poor drying effect of existing drying devices.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cylindrical battery cap drying device, including a base; A drying chamber is provided at one end of the top of the base, and an inlet fan is provided at the top of the drying chamber. A feeding mechanism is provided at the top of the base, and the feeding mechanism includes a circular groove located in the center of the top of the base. An annular tube is provided inside the circular groove, and negative pressure suction nozzles are evenly distributed at the top of the annular tube. A cover is provided at the top of the circular groove, and suction holes corresponding to the negative pressure suction nozzles are evenly distributed at the edge of the cover. A cap body is evenly distributed above the suction holes. An air guide pipe is provided at the center of the inside of the circular groove, and the air guide pipe is evenly connected to the annular pipe through connecting pipes. A negative pressure pump is provided at the center of the top of the cover, and the air inlet of the negative pressure pump is connected to the air guide pipe.

[0006] Preferably, a first drive motor is fixed on the base below the circular groove, and the output end of the first drive motor is connected to the circular groove through a roller.

[0007] The above structure can drive the circular groove to rotate at a constant speed, causing the adsorbed cap body to pass through the drying and pushing stations in sequence, thus realizing continuous automated operation.

[0008] Preferably, the bottom of the drying oven is provided with a fan hood, and the fan hood has a trumpet-shaped structure.

[0009] The above structure can concentrate and evenly guide the hot air in the drying chamber to the cap body on the lower circular groove, avoiding uneven drying caused by the dispersion of hot air and improving drying efficiency and quality.

[0010] Preferably, a filter screen is provided at the top of the drying chamber, and the filter screen is made of activated carbon. Heating tubes are evenly arranged inside the drying chamber below the filter screen.

[0011] The above structure filters out impurities and odors from the air drawn into the drying chamber, and then heats the clean air into hot air through the heating tube, preventing impurities from contaminating the cap body and ensuring the cleanliness of the cap after drying.

[0012] Preferably, a push rod is mounted on the top end of the circular trough away from the drying box via a bracket, and both ends of the bottom of the bracket are fixedly connected to the base. A collection trough is provided on the side of the base away from the drying box.

[0013] The above structure can stably support the push rod to achieve the pushing action, and also allow the pushed dried cap body to fall accurately into the collection tank to complete the automatic collection.

[0014] Preferably, a guide plate is provided at one end of the bottom of the bracket, one end of the push rod passes through the guide plate, and a spring sleeve is fitted on the push rod on one side of the guide plate.

[0015] With the above structure, the guide plate can restrict the push rod to move only along the axial direction to avoid deviation, and the spring sleeve can automatically reset after the push rod is pushed, in preparation for the next push.

[0016] Preferably, a cam is provided at the bottom of the bracket on one side of the push rod, and a second drive motor is fixed at one end of the top of the bracket. The output end of the second drive motor is connected to the cam through a roller.

[0017] The above structure can drive the cam to rotate, which in turn pushes the push rod to extend intermittently, achieving automatic pushing that matches the rotation rhythm of the circular groove and improving material feeding efficiency.

[0018] The advantages of the cylindrical battery cap drying device provided by this utility model are as follows: The system comprises a base, a feeding mechanism, a drying chamber, and a cap body. The feeding mechanism includes a circular groove, a first drive motor, a cap body, an annular tube, a negative pressure nozzle, an air guide pipe, a negative pressure pump, and suction holes. The air inlet of the negative pressure pump is connected to the air guide pipe, which is uniformly connected to the annular tube via connecting pipes. Suction holes matching the negative pressure nozzles are evenly opened on the edge of the cap body. The cap body is conveyed to the surface of the cap body in the circular groove by a vibrating feeding plate. At the same time, the first drive motor drives the circular groove to rotate, so that the cap bodies are adsorbed one by one onto the top of the suction holes. The drying chamber is fixed to one side above the circular groove by a frame. When the cap body rotates to the bottom of the drying chamber, it is dried by the hot air blown out, so that each cap body is independently and flatly fixed on the top of the suction hole without stacking or obstruction. Each cap body can be fully exposed to the hot air coverage of the drying chamber, improving drying efficiency. At the same time, under negative pressure adsorption, the cap body is tightly attached to the surface of the cap body, and the cap body is not prone to slippage when the circular groove rotates and the drying chamber blows air.

[0019] The system consists of a bracket, a cam, a second drive motor, a guide plate, a push rod, and a spring sleeve. The push rod is positioned at the top of the circular groove away from the drying chamber via the bracket. The second drive motor drives the cam to rotate. When the cam rotates to the lifting section, its radius gradually increases, pushing the push rod to overcome the force of the spring sleeve and extend outward. This pushes the dried cap body, which has rotated to the side of the push rod, into the collection groove below. When the cam pushes the push rod outward, the spring sleeve is compressed, storing energy. When the cam rotates away from the lifting section, the stored energy is released, pushing the push rod to quickly and stably retract to its original position, preparing for the next extension. This cycle repeats intermittently, allowing for the automatic unloading of the dried cap body. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 The present invention provides a cylindrical battery cap drying device, including a base 1; A feeding mechanism 2 is provided on the top of the base 1, and the feeding mechanism 2 includes a circular groove 201 located in the center of the top of the base 1. A first drive motor 209 is fixed on the base 1 below the circular groove 201, and the output end of the first drive motor 209 is connected to the circular groove 201 through a roller. An annular tube 202 is provided inside the circular groove 201, and negative pressure suction nozzles 203 are evenly distributed on the top of the annular tube 202. A cover 208 is provided on the top of the circular groove 201, and suction holes 206 corresponding to the negative pressure suction nozzles 203 are evenly distributed on the edge of the cover 208. A cap body 3 is evenly distributed above the suction holes 206. An air guide pipe 204 is provided in the center of the interior of the circular groove 201, and the air guide pipe 204 is evenly connected to the annular tube 202 through a connecting pipe 205. A negative pressure pump 207 is provided in the center of the top of the cover 208, and the air inlet of the negative pressure pump 207 is connected to the air guide pipe 204. The first drive motor 209 is started, which drives the circular groove 201 to start rotating at a constant speed through the roller. At the same time, the negative pressure pump 207 is started, and its air inlet generates negative pressure through the air guide pipe 204. The air guide pipe 204 then transmits the negative pressure to the annular pipe 202 inside the circular groove 201 through the connecting pipe 205. This causes the negative pressure suction nozzles 203, which are evenly distributed at the top of the annular pipe 202, to generate suction force. The suction force acts on the surface of the cover 208 through the suction holes 206, which are evenly distributed at the edge of the top cover 208 of the circular groove 201. The cap body 3 is conveyed to the surface of the cover 208 one by one through the vibrating feeding plate. Under the action of the suction force of the negative pressure suction nozzles 203, the cap body 3 is adsorbed one by one above the suction holes 206 and moves synchronously with the rotation of the circular groove 201. A drying chamber 4 is provided at one end of the top of the base 1, and an inlet fan 12 is provided at the top of the drying chamber 4. A fan hood 5 is provided at the bottom of the drying chamber 4, and the fan hood 5 has a trumpet-shaped structure. A filter screen 13 is provided at the top inside the drying chamber 4, and the filter screen 13 is made of activated carbon. Heating tubes 14 are evenly arranged inside the drying chamber 4 below the filter screen 13. When the suction hole 206 on which the cap body 3 is adsorbed rotates with the circular groove 201 to the bottom of the drying box 4, the intake fan 12 at the top of the drying box 4 is started, and the outside air is drawn into the drying box 4. It first passes through the activated carbon filter 13 at the top of the drying box 4 to filter impurities and odors, and then flows through the heating tubes 14 evenly arranged below the filter 13. It is heated into hot air by the heating tubes 14. The drying box 4 has a built-in temperature sensor to sense the temperature of the hot air. The temperature sensor transmits the temperature signal to the control system for temperature control. This is the prior art. The hot air is evenly blown through the trumpet-shaped wind hood 5 at the bottom of the drying box 4 onto the cap body 3 adsorbed on the suction hole 206 to dry the cap body 3. Each cap body 3 can be fixed independently and flat on the top of the cover 208 without stacking or obstruction. Each cap body 3 can be fully exposed to the hot air coverage of the drying oven 4, improving drying efficiency. At the same time, under negative pressure adsorption, the cap body 3 is tightly attached to the surface of the cover 208. When the circular groove 201 rotates and the drying air blows, the cap body 3 is not easy to slip. A push rod 8 is mounted on the top end of the circular trough 201 away from the drying chamber 4 via a bracket 6, and both ends of the bottom of the bracket 6 are fixedly connected to the base 1. A collection trough 15 is provided on the side of the base 1 away from the drying chamber 4. A guide plate 7 is provided at one end of the bottom of the bracket 6. One end of the push rod 8 passes through the guide plate 7, and a spring sleeve 9 is fitted on the push rod 8 on one side of the guide plate 7. A cam 10 is provided at the bottom of the bracket 6 on one side of the push rod 8, and a second drive motor 11 is fixed at one end of the top of the bracket 6. The output end of the second drive motor 11 is connected to the cam 10 via a roller. After drying, the cap body 3 continues to rotate with the circular groove 201. The second drive motor 11 starts and drives the cam 10 at the bottom of the bracket 6 to rotate via the roller. When the cam 10 rotates to the lifting section, its contour radius gradually increases, pushing the push rod 8 to extend outward along the guide plate 7 at one end of the bottom of the bracket 6. During the extension of the push rod 8, it squeezes the spring sleeve 9 on one side of the guide plate 7 to compress and store energy. At the same time, the push rod 8 pushes the dried cap body 3 away from the suction hole 206. The cap body 3 falls into the collection groove 15 on the side of the base 1 away from the drying box 4. When the cam 10 rotates away from the lifting section, the spring sleeve 9 releases the stored energy and pushes the push rod 8 to quickly retract to its original position along the guide plate 7, preparing for the push of the next dried cap body 3. This cycle repeats, realizing the continuous feeding, drying and automatic unloading of the cap body 3.
