Description

Technical Field

[0001] This utility model belongs to the field of glue coating machine technology, specifically relating to a carbon electric glue coating machine. Background Technology

[0002] Before battery encapsulation, adhesive needs to be applied to the inner peripheral wall of the battery casing opening and the outer peripheral wall of the carbon rod. Adhesive application is a critical step in battery processing, and its quality directly affects the sealing performance of the product. Existing battery adhesive application methods include manual application and machine application. Manual application has low production efficiency, cannot meet the requirements of mass production, and can cause uneven application. Machine application, on the other hand, is not only highly efficient but also provides uniform application, and is widely used by companies.

[0003] Existing glue coating machines typically include a battery holder and a glue injection pump. The battery holder is used to house the battery casing and drive the battery casing to rotate circumferentially. The glue injection pump's injection port extends into the glue injection position inside the battery casing and applies glue to the inner peripheral wall of the battery casing and the outer peripheral wall of the carbon rod. However, the glue injection volume of this type of glue injection pump is not stable. To ensure the glue coating effect, the amount of glue injected will be relatively more, which leads to a higher glue consumption and thus increases the battery production cost.

[0004] Therefore, a carbon battery coating machine is needed to solve the problem that the amount of glue injected by the existing glue injection pump is not stable. In order to ensure the coating effect, the amount of glue injected will be relatively large, which leads to a higher amount of glue used and thus increases the production cost of the battery. Utility Model Content

[0005] The purpose of this invention is to provide a carbon electrocoating machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a carbon battery coating machine, comprising a frame and a feeding mechanism and a coating mechanism mounted on the frame. The feeding mechanism is used to convey battery casings to the coating mechanism, and the coating mechanism is used to coat the battery casings with adhesive. The coating mechanism includes a turret and several coating devices spaced apart along the outer periphery of the turret. Each coating device includes a lifting assembly, a battery holder, and a coating assembly arranged sequentially from bottom to top. The battery holder is used to accommodate batteries. The lifting assembly is used to lift the corresponding battery to the coating position and drive the battery to rotate circumferentially. The coating assembly is used to coat the battery with adhesive. A drying mechanism is provided on the inner sidewall of the frame.

[0007] The adhesive application assembly includes a pump head, a plunger, and a drive unit. The pump head has a pump chamber, and its upper and lower ends are respectively provided with an adhesive inlet and an adhesive outlet communicating with the pump chamber. An adhesive application head is connected to the adhesive outlet. The plunger has a groove extending along its axial direction and penetrating one end face of the plunger on its outer peripheral wall. The end of the plunger near its groove is slidably connected to the pump chamber, and the outer peripheral wall of the plunger is in contact with the inner wall of the pump chamber. The drive unit is connected to the other end of the plunger and is used to drive the plunger to reciprocate axially and rotate circumferentially.

[0008] Initially, the groove is located directly below the glue injection port, making the glue injection port open and the glue outlet closed. When the drive unit drives the plunger to move axially, it draws glue from the glue injection port into the pump chamber along the groove. After a certain amount of glue is drawn, the drive unit drives the plunger to rotate circumferentially, making the groove directly above the glue outlet. At this time, the glue injection port is closed and the glue outlet is open. Finally, the drive unit drives the plunger to return to its axial position, squeezing the glue out of the glue outlet.

[0009] The drying mechanism includes a blower, a blower pipe, a blower head, an electric telescopic rod, a mounting plate, and mounting holes. The blower is located on the inner side wall of the frame. The blower pipe is fixedly installed at the output end of the blower. The blower head is fixedly installed on one side of the blower pipe. The blower pipe is located on one side of the battery holder. The electric telescopic rod is fixedly installed inside the frame. The blower pipe is fixedly installed at the top telescopic end of the electric telescopic rod. The mounting plate is fixedly installed on both sides of the blower. The mounting holes are opened on the side of the mounting plate. The mounting plate is fixed to the frame with bolts.

[0010] It should be noted in the solution that the drive unit includes a servo motor and a stepper motor. The servo motor is connected to the plunger via a connecting rod, and the connecting rod is connected to the plunger via a universal coupling to drive the axial movement of the plunger. A driven gear is sleeved on the connecting rod, and the driven gear is axially slidably connected to the connecting rod and circumferentially limited. The output end of the stepper motor meshes with the driven gear to drive the connecting rod and the plunger to rotate circumferentially.

[0011] It is worth noting that the lower end of the coating head has two symmetrically arranged openings on its outer peripheral wall for simultaneously applying adhesive to the inner wall of the battery case and the outer wall of the carbon rod; a heating ring is fitted on the outer peripheral wall of the coating head for heating the adhesive passing through the coating head.

[0012] Furthermore, it should be noted that the lifting assembly includes a base, a top rod, and a lifting guide rail. The base is fixedly connected to the turret, and the base is provided with a groove extending through its upper and lower ends along its height direction. The top rod is slidably connected in the groove, with one end of the top rod abutting against the bottom of the corresponding battery case and the other end abutting against the lifting guide rail. When the turret drives the top rod to rotate, the top rod will slide up and down with the change in height of the lifting guide rail, thereby driving the battery case to rise or fall. The lower end of the top rod is connected to a roller, which is rotatably connected to the lifting guide rail.

[0013] In a preferred embodiment, the lifting guide rail is distributed in a ring along the outer peripheral wall of the base and includes a descending section and a lifting section connected end to end. The height of the descending section is lower than the height of the lifting section. When the top rod is in the lifting section, the glue applicator extends into the battery case to be glued. When the top rod is in the descending section, the glue applicator retracts from the corresponding battery case.

[0014] In a preferred embodiment, the lifting assembly further includes a drive motor, a transmission belt, and two driven wheels; the drive motor's driving wheel is connected to the two driven wheels via the transmission belt, the transmission belt is in contact with the corresponding outer peripheral wall of the battery casing, and is used to drive the battery casing to rotate circumferentially; the two driven wheels are located at the beginning and end of the lifting section, respectively.

[0015] In a preferred embodiment, the frame is further provided with a pressure wheel, the wheel surface of which is tumblingly connected to the transmission belt to control the belt tension.

[0016] In a preferred embodiment, the feeding mechanism includes a feeding guide rail, a rotating tray, and a feeding plate; the feeding guide rail is connected to the feeding end of the rotating tray and is used to feed battery casings to the rotating tray; the rotating tray is used to arrange and transport the battery casings to the feeding end of the turret; the feeding plate is located at the unloading end of the rotating tray and is used to transfer the battery casings to the battery holder of the turret.

[0017] Compared with the prior art, the carbon electrocoating machine provided by this utility model has at least the following beneficial effects:

[0018] (1) By setting a groove on the outer peripheral wall of the plunger, the groove is located directly below the glue injection port when the glue is drawn. At this time, the glue injection port is connected to the pump chamber through the groove, and the glue outlet is disconnected from the pump chamber. When the drive unit drives the plunger to move axially, the glue will be drawn from the glue injection port into the pump chamber along the groove. After a certain amount of glue is drawn, the drive unit drives the plunger to rotate circumferentially, so that the groove is located directly above the glue outlet. At this time, the glue outlet is connected to the pump chamber through the groove, the glue injection port is closed, and the drive unit drives the plunger to return to its original position axially 20, squeezing the glue out from the glue outlet.

[0019] (2) The amount of glue extracted is controlled by controlling the distance of the axial movement of the plunger, so that each glue application can be carried out according to the preset glue amount. While ensuring the glue application effect, the glue consumption is saved to the maximum extent, thereby saving costs. By setting up a drying mechanism, the glue can be dried quickly after the battery is glued, which facilitates the subsequent processing of the battery and improves the processing efficiency.

[0033] Referring to the figure, a preferred embodiment of the present invention is provided.

[0034] The purpose of this invention is to provide a carbon-electric coating machine that saves glue and allows for rapid glue drying. To better understand this invention, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0035] Basic structure of a glue applicator:

[0036] like Figures 1 to 9 As shown, this utility model provides a carbon battery coating machine. It includes a frame 1 and a feeding mechanism 2 and a coating mechanism 3 disposed on the frame 1. The feeding mechanism 2 is used to convey battery casings to the coating mechanism 3, and the coating mechanism 3 is used to coat the battery casings with adhesive.

[0037] The feeding mechanism 2 includes a feeding guide rail 21, a rotating tray 22, and a feeding plate 23. The feeding guide rail 21 is connected to the feeding end of the rotating tray 22 and is used to feed the battery case to the rotating tray 22. The rotating tray 22 is provided with a slot for accommodating a single battery case and is used to arrange and transfer the battery case to the feeding end of the turret 31 of the gluing mechanism 3. The feeding plate 23 is located at the unloading end of the rotating tray 22 (near the feeding end of the turret 31) and is used to transfer the battery case to the battery holder 322 of the turret 31. This is prior art and will not be described in detail here.

[0038] The adhesive application mechanism 3 includes a turret 31 and several adhesive application devices 32 spaced apart along the outer periphery of the turret 31. Each adhesive application device 32 includes a lifting assembly 321, a battery holder 322, and an adhesive application assembly 323 arranged sequentially from bottom to top. The battery holder 322 is used to accommodate batteries. The lifting assembly 321 is used to lift the corresponding battery 15 to the adhesive application position and drive the battery to rotate circumferentially. The adhesive application assembly 323 is used to apply adhesive to the battery.

[0039] The lifting assembly 321 includes a base 3211, a lifting rod 3212, and a lifting guide rail 3213. The base 3211 is fixedly connected to the turret 31, and the base 3211 is provided with a sliding groove (not shown in the figure) that runs through its upper and lower end faces along its height direction. The lifting rod 3212 is slidably connected in the sliding groove, and one end of the lifting rod 3212 abuts against the bottom of the corresponding battery case, and the other end abuts against the lifting guide rail 3213. When the turret 31 drives the lifting rod 3212 to rotate, the lifting rod 3212 will slide up and down with the change in height of the lifting guide rail 3213, thereby driving the battery case to be lifted or lowered.

[0040] The drying mechanism 5 includes a blower 501, a blower pipe 502, a blower head 503, an electric telescopic rod 504, a mounting plate 505, and mounting holes 506. The blower 501 is located on the inner wall of the frame 1. The blower pipe 502 is fixedly installed at the output end of the blower 501. The blower head 503 is fixedly installed on one side of the blower pipe 502. The blower pipe 502 is located on one side of the battery holder 322. The electric telescopic rod 504 is fixedly installed inside the frame 1. The blower pipe 502 is fixedly installed on the electric telescopic rod 506. At the top telescopic end of the rod 504, the mounting plate 505 is fixedly installed on both sides of the blower 501. The mounting hole 506 is opened on the side end of the mounting plate 505. The mounting plate 505 is fixed to the frame 1 by bolts. The structure of blower 501, blow pipe 502, blower head 503, electric telescopic rod 504, mounting plate 505 and mounting hole 506 facilitates the rapid drying of the glued battery case, facilitates the subsequent processing of the battery case, improves processing efficiency and enhances practicality.

[0041] The lower end of the push rod 3212 is connected to a roller 3214, which is rotatably connected to the lifting guide rail 3213. The roller 3214 can reduce the friction between the lower end of the push rod 3212 and the lifting guide rail 3213, making the rotation of the push rod 3212 smoother.

[0042] The lifting guide rail 3213 is arranged in a ring along the outer peripheral wall of the base 3211, and includes a descending section 3213a and a lifting section 3213b connected end to end. The height of the descending section 3213a is lower than the height of the lifting section 3213b, and the connection between the two ends of the descending section 3213a and the lifting section 3213b is a smooth transition connection. When the top rod 3212 rotates circumferentially with the turret 31, it slides up and down with the change in height of the descending section 3213a and the lifting section 3213b, thereby driving the battery case to be lifted to the glue application position or lowered to reset. In other words, when the top rod 3212 is located in the lifting section 3213b, the glue application head 3233 extends into the battery case to be glued, and when the top rod 3212 is located in the descending section 3213a, the glue application head 3233 retracts from the corresponding battery case.

[0043] The lifting assembly 321 also includes a drive motor 3215, a transmission belt 3216, and two driven pulleys 3217. The drive pulley of the drive motor 3215 is connected to the two driven pulleys 3217 via the transmission belt 3216. The transmission belt 3216 is in contact with the corresponding outer peripheral wall of the battery case and is used to drive the battery case to rotate circumferentially.

[0044] The two driven wheels 3217 are located at the beginning and end of the lifting section 3213b, respectively, so that the transmission belt 3216 can only be in contact with the battery casing located in the lifting section 3213b, and only needs to drive the battery casing located in the lifting section 3213b to rotate circumferentially.

[0045] The frame 1 is also equipped with a pressure wheel 3218. The wheel surface of the pressure wheel 3218 is rolledly connected to the transmission belt 3216, which can control the tension of the belt.

[0046] The adhesive application assembly 323 includes a pump head 3231, a plunger 3232, and a drive unit. The pump head 3231 has a pump chamber, and its upper and lower ends are respectively provided with an adhesive inlet 3231a and an adhesive outlet 3231b communicating with the pump chamber. An adhesive application head 3233 is connected to the adhesive outlet 3231b. The outer peripheral wall of the plunger 3232 has a groove 3232a extending along its axial direction and penetrating one end face of the plunger 3232 (the groove 3232a is formed by setting a cross-section on the outer peripheral wall of the plunger 3232). One end of the plunger 3232 near its groove 3232a is slidably connected to the pump chamber, and the outer peripheral wall of the plunger 3232 is in contact with the inner wall of the pump chamber. The drive unit is connected to the other end of the plunger 3232 and is used to drive the plunger 3232 to move axially and circumferentially.

[0047] Initially, the groove 3232a is located directly below the glue inlet 3231a, making the glue inlet 3231a open and the glue outlet 3231b closed. When the drive unit drives the plunger 3232 to move axially, glue is drawn from the glue inlet 3231a into the pump chamber along the groove 3232a. After a certain amount of glue is drawn, the drive unit drives the plunger 3232 to rotate circumferentially, making the groove directly above the glue outlet 3231b. At this time, the glue inlet 3231a is closed and the glue outlet 3231b is open. Finally, the drive unit drives the plunger 3232 to return to its axial position, squeezing the glue out of the glue outlet 3231b.

[0048] This invention features a groove 3232a on the outer peripheral wall of the plunger 3232. During glue extraction, the groove 3232a is positioned directly below the glue inlet 3231a. At this time, the glue inlet 3231a is connected to the pump chamber through the groove 3232a, while the glue outlet 3231b is disconnected from the pump chamber. When the drive unit drives the plunger 3232 to move axially, it draws glue from the glue inlet 3231a along the groove 3232a into the pump chamber. After a measured amount of glue is extracted, the drive unit drives the plunger 3232 to rotate circumferentially, causing... The groove is located directly above the glue outlet 3231b. At this time, the glue outlet 3231b is connected to the pump chamber through the groove 3232a. The glue inlet 3231a is closed, and the drive unit drives the plunger 3232 to return to its axial position, squeezing the glue out of the glue outlet 3231b. This invention controls the amount of glue extracted by controlling the distance of the axial movement of the plunger 3232, so that each application can be made according to the preset amount of glue. While ensuring the glue application effect, it saves glue consumption to the maximum extent, thereby saving costs.

[0049] The drive unit includes a servo motor 3234 and a stepper motor 3235 (both servo motor 3234 and stepper motor 3235 are geared motors). The servo motor 3234 is connected to the connecting rod 3236 for transmission. The connecting rod 3236 is connected to the plunger 3232 through a universal coupling 4, thereby driving the plunger 3232 to move axially. A driven gear 3237 is sleeved on the connecting rod 3236. The driven gear 3237 is axially slidably connected to the connecting rod 3236 and is circumferentially limited. The output end of the stepper motor 3235 meshes with the driven gear 3237 for transmission, and is used to drive the connecting rod 3236 and the plunger 3232 to rotate circumferentially.

[0050] The lower end of the adhesive applicator 3233 has two symmetrically arranged openings 3233a on its outer peripheral wall, used to simultaneously apply adhesive to the inner wall of the battery casing and the outer wall of the carbon rod, thereby achieving synchronous adhesive application and improving application efficiency. A heating ring 3233b is fitted onto the outer peripheral wall of the adhesive applicator 3233 to heat the adhesive passing through it, preventing it from cooling and solidifying during transport. The heating ring 3233b is a self-regulating ceramic heating ring, capable of maintaining a constant temperature for the adhesive flowing through the adhesive applicator 3233.

[0051] The specific adhesive application steps of this utility model are as follows:

[0052] First, the feeding guide rail 21 conveys the battery casings to the transfer tray 22. The transfer tray 22 arranges and transports the battery casings to the feeding end of the turret 31 of the gluing mechanism 3 (located at the descending section 3213a of the lifting guide rail 3213). The feeding plate 23 transfers the battery casings to the battery holder 322 of the turret 31. Then, the push rod 3212 rotates circumferentially with the turret 31 and slides from the descending section 3213a to the lifting section 3213b. As the height of the lifting guide rail 3213 increases, the push rod 3212 lifts the battery casings to the gluing position. During this process, the drive unit has driven the plunger 3232 to move axially and dispenses a measured amount of glue from the glue inlet 3231a along the groove 3. 232a is drawn into the pump chamber; subsequently, the outer peripheral wall of the battery case located in the lifting section 3213b will be in close contact with the transmission belt 3216, thus rotating circumferentially under the drive of the transmission belt 3216; during the rotation of the battery case, the drive unit drives the plunger 3232 to rotate 180 degrees circumferentially and then return to its axial position, squeezing the glue out from the glue outlet 3231b, and the glue applicator 3233 located at the glue application position applies glue to the inner wall of the battery case and the outer wall of the carbon rod; finally, after the glue application is completed, the push rod 3212 rotates circumferentially with the turret 31 to the lowering section 3213a, the battery case descends and returns to its original position with the push rod 3212, and is transferred out of the turret 31 at the material discharge end of the turret 31 to enter the next inspection process.

[0053] During the process of the battery casing descending and resetting with the top rod 3212, the adhesive on the surface of the battery casing is quickly dried by turning on the blower 501 and using the blower head 503, which facilitates subsequent processing of the battery casing, improves processing efficiency, and enhances practicality.

[0054] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
