Description

Technical Field

[0001] The invention belongs to the technical field of sealing glue coating, in particular to a sealing glue coating device for alkaline batteries. Background Art

[0002] Alkaline batteries have an electrode group consisting of a positive electrode plate, a negative electrode plate and a separator. Generally, alkaline batteries are manufactured in the following manner: after the electrode group consisting of the positive electrode, the negative electrode and the separator is housed in a casing that also serves as the negative terminal, an alkaline electrolyte is injected, and then the upper end opening of the casing is sealed with a sealing body. The sealing body has a cover plate and positive and negative terminals electrically connected to the cover plate. After the cover plate is docked with the casing, a sealing glue needs to be applied to the joint between the cover plate and the casing so that the sealing glue seals the joint between the cover plate and the casing, and then the alkaline electrolyte is poured into the casing through the opening opened at the upper end of the cover plate, thereby completing the production of the alkaline battery.

[0003] At present, when the conventional sealing glue coating device coats the sealing glue to seal the joint of the alkaline battery shell, the battery shell is clamped and fixed, and then the coating nozzle is controlled to coat the sealing glue around the joint of the battery shell. After the sealing glue coating is completed, a scraper is needed to smooth the sealing glue coated on the joint of the battery shell to complete the sealing operation of the battery shell, and then alkaline electrolyte is poured into the inner cavity of the alkaline battery shell. After the pouring is completed, the alkaline electrolyte pouring port of the alkaline battery shell is sealed.

[0004] A patent application with publication number CN114950855B discloses an alkaline battery environmentally friendly sealing glue coating process and equipment. According to the patent, the sliding block in the carrier drives the alkaline battery to rotate rapidly by the movement of the first tooth and the second tooth. At the same time, the external air pressure device pressurizes the glue injection cylinder, the pressure in the glue injection cylinder increases, and the sealant is sprayed out from the glue injection port. The alkaline battery can be sprayed with sealing glue. A finer glue injection port than the prior art can be adopted. Multiple coating methods are adopted to increase the fault tolerance rate and ensure the uniformity of coating. Then, two sets of glue injection cylinders are used to complete the coating during the transportation process of the alkaline battery. While ensuring the yield rate, the coating efficiency is accelerated, the automatic feeding and automatic coating process is realized, and the worker cost is reduced.

[0005] The above-mentioned prior art still has some problems in actual use. Since the coating nozzle is controlled to spray the sealing glue around the interface of the battery shell, if the coating nozzle is controlled to rotate too fast, the sealing glue will be unevenly coated at the interface of the battery shell. Conversely, if the coating nozzle is controlled to rotate too slowly, it will cause excessive coating of the sealing glue at the interface of the battery shell, resulting in unevenness of the glue during the drying or curing process, thereby forming an incomplete sealing layer at the joint of the alkaline battery shell, affecting the sealing of the inner cavity of the alkaline battery.

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Embodiment 1:

[0024] like Figures 1 to 9 As shown, a sealing glue coating device for alkaline batteries according to an embodiment of the present invention comprises a workbench 1, the lower end of the workbench 1 is provided with universal wheels 3 at four corners, the upper end surface of the workbench 1 is provided with a mounting groove 23, and the inner cavity of the mounting groove 23 is provided with a mounting frame 4, the inner cavity of the mounting frame 4 is rotatably connected with a rotating disk 5, and the upper end surface of the rotating disk 5 is used to place an alkaline battery body 6, an electric push rod 7 is fixedly connected to one side of the upper end surface of the workbench 1, the piston rod end of the electric push rod 7 is fixedly connected to a support frame 8, and the lower end of the support frame 8 is provided with a coating auxiliary component 15; The coating auxiliary component 15 includes a through groove 25 opened at the lower end of the support frame 8, a sliding rod 26 is fixedly connected to the inner cavity of the through groove 25, and the servo push rod 12 is slidably connected to the outside of the sliding rod 26, a supporting spring 27 is fixedly connected to the inner wall of the through groove 25, and one end of the supporting spring 27 is fixedly connected to the servo push rod 12, the piston rod end of the servo push rod 12 is fixedly connected to an annular fixing frame 151, the lower end of the annular fixing frame 151 is fixedly connected to a U-shaped fixing frame 152, the inner cavity of the U-shaped fixing frame 152 is rotatably connected to a pulley 153, and the inner cavity of the annular fixing frame 151 is installed with a coating nozzle 11.

[0025] Specifically, in the prior art, the battery shell is clamped and fixed, and then the coating nozzle is controlled to coat the sealing glue around the interface of the battery shell. After the sealing glue is coated, the sealing glue coated on the interface of the battery shell is smoothed by a scraper to complete the sealing operation of the battery shell. However, since the coating nozzle is controlled to spray the sealing glue around the interface of the battery shell, if the coating nozzle is controlled to rotate too fast, the sealing glue coating on the interface of the battery shell will be uneven. On the contrary, if the coating nozzle is controlled to rotate too slowly, the sealing glue coating on the interface of the battery shell will be excessive, resulting in uneven glue during the drying or curing process, thereby forming an incomplete sealing layer at the joint of the alkaline battery shell, affecting the sealing of the inner cavity of the alkaline battery. The present invention places the alkaline battery body 6 on the rotating disk 5, and then starts the servo electric push rod 7 to drive the support frame 8 to move downward, and the support frame 8 drives the servo push rod 12 to move downward, and at the same time, the servo push rod 12 drives the annular fixing frame 151 to move downward, so that the annular fixing frame 151 drives the coating nozzle 11 to move synchronously, so that the nozzle of the coating nozzle 11 is aligned with the interface of the alkaline battery body 6 that needs to be coated, and then the servo push rod 12 is bounced up by the support spring 27, and the servo push rod 12 is slid outside the slide rod 26 to move, so that the servo push rod 12 drives the annular fixing frame 151 to move synchronously, and at the same time, the annular fixing frame 151 drives the U-shaped fixing frame 152 to move, and the U-shaped fixing frame 152 drives the pulley 153 moves synchronously with the alkaline battery body 6 to contact the alkaline battery body 6, so that the coating nozzle 11 can be accurately aligned with the interface of the alkaline battery body 6, and the coating nozzle 11 and the interface of the alkaline battery body 6 are controlled to maintain the required spraying distance, and then the alkaline battery body 6 is driven to rotate, and the coating nozzle 11 is controlled to spray the sealing glue, so that the sealing glue rotates with the alkaline battery body 6 and is evenly coated on the interface of the alkaline battery body 6. During the rotation of the alkaline battery body 6, the pulley 153 slides on the outside of the alkaline battery body 6. When sliding on the corners of the alkaline battery body 6, the pulley 153 pushes the U-shaped fixing frame 152, and the U-shaped fixing frame 152 drives the annular fixing frame 151 to move, and the annular fixing frame 151 is also driven to rotate. The shaped fixing frame 151 drives the coating nozzle 11 to move synchronously, so as to always ensure that the coating nozzle 11 and the interface of the alkaline battery body 6 maintain a corresponding distance, so as to prevent the coating nozzle 11 from moving to the corners of the alkaline battery body 6. Because the distance between the coating nozzle 11 and the interface of the alkaline battery body 6 becomes smaller, the sealing glue at the corners of the alkaline battery body 6 is excessively coated, resulting in a waste of sealing glue. In addition, excessive coating of sealing glue will cause unevenness of the glue during drying or curing, thereby forming an incomplete sealing layer at the interface of the alkaline battery body 6, affecting the sealing of the inner cavity of the alkaline battery body 6, thereby solving the problem that the existing sealing glue coating device for alkaline batteries is used to coat the sealing glue at the interface of the alkaline battery shell. The battery shell is clamped and fixed, and then the coating nozzle is controlled to coat the sealing glue around the interface of the battery shell. After the sealing glue is coated, the sealing glue coated on the interface of the battery shell is smoothed with a scraper to complete the sealing operation of the battery shell. However, since the coating nozzle is controlled to spray the sealing glue around the interface of the battery shell, if the coating nozzle is controlled to rotate too fast, the sealing glue coating on the interface of the battery shell will be uneven. Conversely, if the coating nozzle is controlled to rotate too slowly, the sealing glue coating on the interface of the battery shell will be excessive, resulting in uneven glue during the drying or curing process, thereby forming an incomplete sealing layer at the joint of the alkaline battery shell, affecting the sealing of the inner cavity of the alkaline battery.

[0026] like Figure 1 , Figures 3 to 5 As shown, a threaded interface 9 is provided at the upper end of the support frame 8, and a folding conduit 10 is fixedly connected to the lower end of the support frame 8. One end of the folding conduit 10 is fixedly connected to the coating nozzle 11, and one end of the folding conduit 10 is connected to the threaded interface 9.

[0027] Specifically, before applying the sealing glue to the interface of the alkaline battery body 6, the external sealing glue delivery pipe is installed and connected to the threaded interface 9. When the servo push rod 12 is used to drive the coating nozzle 11 to move downward and calibrate with the interface of the alkaline battery body 6, the coating nozzle 11 will drive the folding catheter 10 to perform telescopic adjustment, and then the external sealing glue delivery pipe is used to discharge the sealing glue into the inner cavity of the threaded interface 9, and enter the inner cavity of the folding catheter 10 to flow into the coating nozzle 11, and then the coating nozzle 11 is controlled to coat the interface of the alkaline battery body 6, thereby improving the efficiency of coating the sealing glue at the interface of the alkaline battery.

[0028] like Figure 1 and Figure 5 As shown, four hinges are fixedly connected to both sides of one end of the workbench 1, and two cabinet doors 2 are fixedly connected to one end of the four hinges. The two cabinet doors 2 are butt-jointed and fixed to seal the inner cavity of the workbench 1.

[0029] like Figure 3 and Figure 6 As shown, a cross slot 24 is provided in the middle of the lower end surface of the rotating disk 5, and two grooves 21 are symmetrically provided on the upper end surface of the rotating disk 5, and the inner cavities of the two grooves 21 are fixedly connected with support slides 18, and the outer cavities of the support slides 18 are slidably connected with a limit stop block 20, and the inner wall of the groove 21 is fixedly connected with a spring 19, and one end of the spring 19 is fixedly connected to the limit stop block 20.

[0030] Specifically, before the alkaline battery body 6 is coated with the sealing glue, the alkaline battery body 6 is placed on the upper end of the rotating disk 5 and the alkaline battery body 6 is installed between the two limit blocks 20. At the same time, the limit block 20 is bounced up by the spring 19, and then the limit block 20 is slid outside the supporting slide column 18, so that the limit block 20 clamps the alkaline battery body 6 and positions it in the middle of the rotating disk 5. After the alkaline battery body 6 is clamped and positioned, the rotating disk 5 is driven to rotate, so that the rotating disk 5 drives the alkaline battery body 6 to rotate, and then the coating nozzle 11 is controlled to approach the interface of the alkaline battery body 6, so that the coating nozzle 11 can be used to evenly coat the sealing glue on the interface of the alkaline battery body 6 as the alkaline battery body 6 rotates, thereby improving the efficiency of coating the sealing glue on the interface of the alkaline battery, avoiding the problem that the coating nozzle is difficult to accurately coat around the interface of the battery shell when the coating nozzle is controlled to spray the sealing glue around the interface of the battery shell.

[0031] like Figure 3 As shown, a fixing frame 17 is installed on both walls of the inner cavity of the workbench 1 , a servo motor 16 is installed in the inner cavity of the fixing frame 17 , a cross plug block is fixedly connected to the output shaft end of the servo motor 16 , and the cross plug block is plugged into the cross slot 24 .

[0032] Specifically, the servo motor 16 is installed in the inner cavity of the fixing frame 17, and the servo motor 16 is inserted into the inner cavity of the cross slot 24 by means of a cross plug block. Then, the servo motor 16 is started to drive the cross plug block to rotate, and the cross plug block cooperates with the cross slot 24 to drive the rotating disk 5 to rotate, and then the rotating disk 5 drives the alkaline battery body 6 to rotate, so as to cooperate with the coating nozzle 11 to coat the sealing glue on the interface of the alkaline battery.

[0033] like Figure 4 and Fig. 9 As shown, an L-shaped fixing frame 154 is fixedly connected to one side of the annular fixing frame 151, a receiving groove 157 is opened inside the L-shaped fixing frame 154, a micro spring 156 is fixedly connected to the bottom of the inner cavity of the receiving groove 157, and a T-shaped scraper 155 is fixedly connected to one end of the micro spring 156, and one end of the T-shaped scraper 155 is set in an acute triangle shape, and the acute angle is set in a semicircular arc shape, which is used for scraping and applying sealing glue.

[0034] Specifically, when the alkaline battery body 6 is driven to rotate and the sealing glue is applied, the L-shaped fixing frame 154 is driven to move synchronously by the annular fixing frame 151, and the L-shaped fixing frame 154 drives the T-shaped scraper 155 to fit the surface of the alkaline battery body 6, and at the same time, the T-shaped scraper 155 slides into the inner cavity of the storage groove 157, and squeezes the micro spring 156 in the inner cavity of the storage groove 157, and then the T-shaped scraper 155 is bounced up by the rebound force of the micro spring 156, so that the T-shaped scraper 155 and the surface of the alkaline battery body 6 are closely fitted, and as the alkaline battery body 6 rotates, the sealing glue is applied to the interface of the alkaline battery body 6 by the coating nozzle 11, and at the same time, the sealing glue applied to the interface of the alkaline battery body 6 is smoothed by the T-shaped scraper 155 as the alkaline battery body 6 rotates, and when encountering the alkaline battery body 6, the sealing glue applied to the interface of the alkaline battery body 6 is smoothed by the T-shaped scraper 155. When the T-shaped scraper 155 is applied to the corner of the alkaline battery body 6, the T-shaped scraper 155 will slide into the inner cavity of the storage groove 157 and always fit with the surface of the alkaline battery body 6, thereby effectively smoothing the sealing glue applied on the interface of the alkaline battery body 6, thereby solving the problem that when the sealing glue coating device for existing alkaline batteries coats the sealing glue on the alkaline battery shell joint, it is necessary to wait until the entire alkaline battery shell joint is coated with the sealing glue before the scraper can be used to smooth the sealing glue applied on the battery shell joint. If during the coating process, the sealing glue is affected by the external temperature and other environmental factors, the battery shell joint is not completely coated with the sealing glue, and the previously coated sealing glue is dried or solidified, it is difficult for the subsequent scraper to smooth the coated sealing glue to form a sealing layer, thereby affecting the sealing problem of the alkaline battery inner cavity.

[0035] Embodiment 2:

[0036] like Figure 3 and Figure 4 As shown, another embodiment of the present invention is: the lower end of the support frame 8 is internally rotatably connected to the first rotating frame 13, the lower end of the first rotating frame 13 is fixedly connected to an annular pressing ring 14, and the lower end of the annular pressing ring 14 is provided with an anti-slip rubber pad.

[0037] Specifically, when the electric push rod 7 is started to drive the support frame 8 to move downward, the support frame 8 drives the first rotating frame 13 to move downward, and at the same time, the first rotating frame 13 drives the annular pressing ring 14 to move downward, so that the annular pressing ring 14 is in contact with the upper end of the alkaline battery body 6, and the annular pressing ring 14 presses and fixes the alkaline battery body 6. In the process of driving the rotating disk 5 to rotate, the rotating disk 5 drives the alkaline battery body 6 to rotate, and at the same time, the alkaline battery body 6 drives the annular pressing ring 14 to rotate, so that the annular pressing ring 14 drives the first rotating frame 13 to rotate inside the support frame 8, thereby ensuring the stability of the rotation of the alkaline battery body 6, and the support frame 8 drives the first rotating frame 13 to move downward, and the first rotating frame 13 pushes the annular pressing ring 14 to press the alkaline battery body 6, so as to ensure the sealing of the interface of the alkaline battery body 6 and prevent a large gap from appearing at the interface of the alkaline battery body 6, and then cooperate with the sealing glue coating to improve the sealing of the inner cavity of the alkaline battery body 6.

[0038] like Figure 3 , Figure 6 and Figure 7 As shown, a battery coating clamping assembly 22 is arranged inside the rotating disk 5, and the battery coating clamping assembly 22 includes a rotating groove 221 opened inside the rotating disk 5, and two limiting slide grooves 231 are symmetrically opened on the upper end surface of the rotating disk 5, and the inner cavities of the two limiting slide grooves 231 are connected to the rotating groove 221, and the inner cavities of the limiting slide grooves 231 are slidably connected to the limiting slider 225, and the upper end of the limiting slider 225 is fixedly connected with a clamping block 226, and the outside of the clamping block 226 is provided with an anti-slip rubber layer.

[0039] like Figure 3 , Figure 6 and Figure 7 As shown, the inner cavity of the rotating groove 221 is rotatably connected to a rotating shaft 222 , the outer portion of the rotating shaft 222 is fixedly connected to a second rotating frame 223 , both ends of the second rotating frame 223 are rotatably connected to a pull rod 224 , and one end of the pull rod 224 is rotatably connected to a limiting slider 225 .

[0040] like Figure 3 , Figure 6 and Figure 7 As shown, a driven sprocket 227 is fixedly connected to the outside of the rotating shaft 222, and a toothed belt 228 is transmission-connected to the outside of the driven sprocket 227. One end of the toothed belt 228 is transmission-connected to a driving sprocket 229. A knob 230 is fixedly connected to the inside of the upper end of the driving sprocket 229, and the knob 230 is rotationally connected to the rotating disk 5.

[0041] Specifically, before applying the sealing glue to the interface of the alkaline battery body 6, the alkaline battery body 6 is placed between the two limit blocks 20, and then the knob 230 is driven to rotate, and the knob 230 drives the transmission sprocket 229 to rotate, and the transmission sprocket 229 drives the toothed belt 228 to rotate, and then drives the driven sprocket 227 to rotate. During the rotation of the driven sprocket 227, the rotating shaft 222 is driven to rotate, and the rotating shaft 222 drives the second rotating frame 223 to rotate, and the transmission pull rod 224 is rotated, so that the pull rod 224 pulls the limit slider 225 to slide in the inner cavity of the limit slide groove 231 to move, and during the movement of the limit slider 225, it drives the clamping blocks 226 to move closer to each other. The knob 230 is provided with a latch on the outside of the rotating disk 5, and is plugged into the rotating disk 5, so as to prevent the clamping block 226 from loosening after the clamping block 226 has clamped and fixed the alkaline battery body 6, thereby preventing the clamping block 226 from loosening and affecting the clamping and fixing effect of the alkaline battery body 6. This solves the problem that when the sealing glue coating device for alkaline batteries is used to coat the sealing glue on the butt joint of the alkaline battery shell, if the alkaline battery shell moves outside the rotating disk, it will affect the uniformity of the coating nozzle coating the sealing glue on the butt joint of the alkaline battery shell.

[0042] The working principle is as follows: the alkaline battery body 6 is placed on the rotating disk 5, and then the servo electric push rod 7 is started to drive the support frame 8 to move downward, and the support frame 8 drives the servo push rod 12 to move downward, and at the same time, the servo push rod 12 pushes the annular fixing frame 151 to move downward, so that the annular fixing frame 151 drives the coating nozzle 11 to move synchronously, so that the nozzle of the coating nozzle 11 is aligned with the interface of the alkaline battery body 6 that needs to be coated, and then the servo push rod 12 is bounced up by the support spring 27, and the servo push rod 12 is slid outside the slide rod 26 to move, so that the servo push rod 12 drives the annular fixing frame 151 to move synchronously, and at the same time, the annular fixing frame 151 drives the U-shaped fixing frame 152 to move, and the U-shaped fixing frame 152 drives the pulley 153 to move synchronously and contact the alkaline battery body 6, so that the coating nozzle 11 can be accurately aligned with the interface of the alkaline battery body 6, and the coating nozzle 11 and the alkaline battery body 6 are controlled to maintain the required spacing for spraying, and then the alkaline battery body 6 is driven to rotate, and at the same time The coating nozzle 11 is controlled to spray the sealing glue, so that the sealing glue rotates with the alkaline battery body 6 and is evenly coated on the interface of the alkaline battery body 6. During the rotation of the alkaline battery body 6, the pulley 153 slides on the outside of the alkaline battery body 6. When sliding on the corners of the alkaline battery body 6, the pulley 153 pushes the U-shaped fixing frame 152, and the U-shaped fixing frame 152 drives the annular fixing frame 151 to move. At the same time, the annular fixing frame 151 drives the coating nozzle 11 to move synchronously, so that the coating nozzle 11 can always be Ensure that the coating nozzle 11 and the interface of the alkaline battery body 6 maintain a corresponding distance to prevent the coating nozzle 11 from moving to the corners of the alkaline battery body 6. The distance between the coating nozzle 11 and the interface of the alkaline battery body 6 becomes smaller, resulting in excessive coating of the sealing glue at the corners of the alkaline battery body 6, causing waste of the sealing glue. In addition, excessive coating of the sealing glue will cause the glue to be uneven during drying or curing, thereby forming an incomplete sealing layer at the interface of the alkaline battery body 6, affecting the sealing of the inner cavity of the alkaline battery body 6. When the alkaline battery body 6 is driven to rotate for coating the sealing glue, the L-shaped fixing frame 154 is driven to move synchronously through the annular fixing frame 151, and the L-shaped fixing frame 154 drives the T-shaped scraper 155 to fit the surface of the alkaline battery body 6, and at the same time, the T-shaped scraper 155 slides into the inner cavity of the receiving groove 157 and squeezes the micro spring 156 in the inner cavity of the receiving groove 157, and then the T-shaped scraper 155 is bounced up by the rebound force of the micro spring 156, so that the T-shaped scraper 155 is closely fitted to the surface of the alkaline battery body 6, and As the alkaline battery body 6 rotates, the coating nozzle 11 is used to coat the sealing glue on the interface of the alkaline battery body 6. At the same time, the T-shaped scraper 155 is used to smooth the sealing glue coated on the interface of the alkaline battery body 6 as the alkaline battery body 6 rotates. When encountering the corners of the alkaline battery body 6, the T-shaped scraper 155 will slide into the inner cavity of the receiving groove 157 and always fit with the surface of the alkaline battery body 6, thereby effectively smoothing the sealing glue coated on the interface of the alkaline battery body 6. Before applying the sealing glue to the interface of the alkaline battery body 6, the alkaline battery body 6 is placed between the two limit blocks 20, and then the knob 230 is driven to rotate, and the knob 230 drives the transmission sprocket 229 to rotate, and the transmission sprocket 229 drives the transmission belt 228 to rotate, and then drives the driven sprocket 227 to rotate. During the rotation of the driven sprocket 227, the rotating shaft 222 is driven to rotate, and the rotating shaft 222 drives the second rotating frame 223 to rotate, and the transmission pull rod 224 is rotated, so that the pull rod 224 pulls the limit slider 225. The slider 225 moves in the inner cavity of the limiting slide groove 231, and the limiting slider 225 drives the clamping block 226 to move closer to each other during the movement, so that the clamping block 226 clamps and fixes the alkaline battery body 6, thereby preventing the alkaline battery body 6 from moving outside the rotating disk 5 during the driving rotation of the rotating disk 5. In addition, a latch is provided on the outside of the knob 230 and is plugged into the rotating disk 5 to prevent the clamping block 226 from rotating after the clamping block 226 clamps and fixes the alkaline battery body 6, thereby affecting the clamping and fixing effect of the alkaline battery body 6.
