A cam intermittent glue pressing mechanism and a glue sticking device

Abstract

This utility model discloses a cam-driven intermittent adhesive pressing mechanism and an adhesive applicator. A drive assembly drives a connecting rod to rotate a cam. Since the adhesive roller is parallel to the connecting rod and the cam is in a rolling connection with the adhesive roller, during the cam's rotation, when the outermost edge of the cam abuts against the adhesive roller, the adhesive roller, slidably connected to the frame, is compressed and moves outward relative to the connecting rod, completing the adhesive pressing process. Furthermore, with the help of a reset assembly, the adhesive roller returns to its original position after each pressing cycle, preparing for the next pressing. The cam's cycle is stable, with consistent intervals and position heights for each cycle, ensuring precise pressing of each adhesive strip.

Description

Technical Field

[0001] This utility model relates to the field of battery adhesive application, specifically to a cam-based intermittent adhesive pressing mechanism and adhesive application equipment. Background Technology

[0002] In current battery production processes, tape application is a crucial step in battery manufacturing or assembly, primarily used for securing the battery, providing insulation, shock absorption, and auxiliary heat dissipation. To ensure the tape's adhesion, a further pressing step is required after application. Traditional intermittent pressing uses perforations on the edge of the tape for positioning, relying on the location of these perforations for precise pressing, which suffers from low accuracy. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a cam-based intermittent adhesive pressing mechanism and adhesive application equipment, which can solve the problem of low accuracy of the existing adhesive pressing method.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: On the one hand, a cam intermittent pressing mechanism is provided, including a frame, a drive assembly, a transmission assembly, a reset assembly, and a pressing roller slidably connected to the frame. The transmission assembly includes a connecting rod and a cam mounted on the connecting rod. The drive assembly is used to drive the connecting rod to rotate so as to drive the cam to rotate. The pressing roller is arranged parallel to the connecting rod. The cam rolls against the pressing roller and is used to periodically press the pressing roller outward. The reset assembly is connected between the frame and the pressing roller. The reset assembly is used to reset the pressing roller after the cam presses the pressing roller outward.

[0005] As a further improvement to the above technical solution, a guide assembly is also included, which includes a slide rail and a slider slidably connected to the slide rail. The slide rail is mounted on the frame, and the length direction of the slide rail is the same as the arrangement direction of the rubber pressure roller and the connecting rod. The end of the rubber pressure roller is mounted on the slider. The cam rolls against the slider, and the reset assembly is connected between the slider and the frame.

[0006] As a further improvement to the above technical solution, the slider is provided with a roller that rotates toward one side of the connecting rod, and the roller rolls and abuts against the cam.

[0007] As a further improvement to the above technical solution, the reset assembly includes a tension spring and a mounting block. The mounting block is fixedly mounted on the frame. One end of the tension spring is connected to the mounting block, and the other end is connected to the slider. The length direction of the tension spring is the same as the length direction of the slide rail.

[0008] As a further improvement to the above technical solution, two reset components and two guide components are provided. The two guide components are respectively connected to both ends of the adhesive roller, and the two reset components are respectively connected to the two guide components.

[0009] As a further improvement to the above technical solution, the drive assembly includes a motor, a drive gear, and a driven gear. The stator of the motor is mounted on the frame, its rotor is connected to the drive gear, the drive gear meshes with the driven gear, and the driven gear is connected to the end of the connecting rod.

[0010] As a further improvement to the above technical solution, the diameter of the driving gear is smaller than the diameter of the driven gear, and the diameter of the driven gear is larger than the diameter of the cam.

[0011] As a further improvement to the above technical solution, it also includes a photoelectric sensor and a PLC controller. The photoelectric sensor is mounted on the frame and used to detect the position of the adhesive tape. The input terminal of the PLC controller is electrically connected to the output terminal of the photoelectric sensor, and the output terminal of the PLC controller is electrically connected to the input terminal of the drive assembly.

[0012] As a further improvement to the above technical solution, a limiting component is provided on the frame. The limiting component includes a bracket and two limiting wheels, both of which are mounted on the bracket. The bracket is mounted on the frame, and the connecting rod abuts between the two limiting wheels.

[0013] On the other hand, an adhesive applicator is provided, including a transmission mechanism and the aforementioned intermittent cam pressing mechanism, wherein the transmission mechanism is used to transport the battery to be pressed to the adhesive roller for pressing.

[0014] The beneficial effects of this invention are as follows: The drive assembly drives the connecting rod to rotate the cam. Since the glue roller is parallel to the connecting rod and the cam is in a rolling connection with the glue roller, during the rotation of the cam, when the outermost part of the cam abuts against the glue roller, the glue roller, being slidably connected to the frame, is squeezed and moves outward relative to the connecting rod, completing the glue pressing process. Furthermore, under the action of the reset assembly, after one glue pressing cycle, the glue roller can return to its original position, preparing for the next glue pressing cycle. The cam's cycle is stable, and the interval time and position height of each motion cycle are consistent, ensuring precise pressing of each glue strip. Attached Figure Description

[0023] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0024] Please see Figure 1-3 A preferred embodiment of this utility model provides a cam-driven intermittent adhesive pressing mechanism, including a frame 1, a drive assembly 2, a transmission assembly 3, a reset assembly 4, a guide assembly 5, a photoelectric sensor 6, a PLC controller (not shown in the figure), and an adhesive pressing roller 7 slidably connected to the frame 1. Please refer to [link to relevant documentation]. Figure 3The photoelectric sensor 6 is mounted on the frame 1 and is used to detect the position of the adhesive tape. The input terminal of the PLC controller is electrically connected to the output terminal of the photoelectric sensor 6, and the output terminal of the PLC controller is electrically connected to the input terminal of the drive assembly 2. The photoelectric sensor 6 detects the position of the adhesive tape at the front end of the adhesive pressing and transmits the data to the PLC controller to calculate the pressing time. Then, the PLC controller controls the drive assembly 2 to drive the transmission assembly 3. The transmission assembly 3 can periodically squeeze the adhesive roller 7. The squeezed adhesive roller 7 moves along the guide assembly 5. The reset assembly 4 is used to restore the squeezed adhesive roller 7 to the initial position for the next adhesive pressing.

[0025] For details, please see Figure 1 and Figure 2 The transmission assembly 3 includes a connecting rod 31 and a cam 32 mounted on the connecting rod 31. The drive assembly 2 drives the connecting rod 31 to rotate, thereby rotating the cam 32. The glue roller 7 is arranged parallel to the connecting rod 31. The cam 32 rolls against the glue roller 7 and is used to periodically squeeze the glue roller 7 outward. The reset assembly 4 is connected between the frame 1 and the glue roller 7. The reset assembly 4 is used to reset the glue roller 7 after the cam 32 squeezes the glue roller 7 outward. The drive assembly 2 drives the connecting rod 31 to rotate the cam 32. Since the glue roller 7 is arranged parallel to the connecting rod 31 and the cam 32 is in rolling contact with the glue roller 7, during the rotation of the cam 32, when the outermost part of the cam 32 abuts against the glue roller 7, the glue roller 7 is squeezed and moves outward relative to the connecting rod 31 because the glue roller 7 is slidably connected to the frame 1. The glue pressing is completed during the outward movement. Furthermore, under the action of the reset assembly 4, after one glue pressing is completed, the glue roller 7 can return to its original position to prepare for the next glue pressing. The cam 32 has a stable cycle, and the interval time and position height of each motion cycle are consistent, which can ensure precise pressing of each rubber strip.

[0026] Please see Figure 1 , 2 4. The guide assembly 5 includes a slide rail 51 and a slider 52 slidably connected to the slide rail 51. The slide rail 51 is mounted on the frame 1, and the length direction of the slide rail 51 is the same as the arrangement direction of the glue roller 7 and the connecting rod 31. The end of the glue roller 7 is mounted on the slider 52. The cam 32 rolls against the slider 52. The reset assembly 4 is connected between the slider 51 and the frame 1. When the outermost part of the cam 32 abuts against the slider 52, the slider 52 drives the glue roller 7 to move along the slide rail 51 away from the connecting rod 31. After the glue pressing is completed, under the action of the reset assembly 4, the slider 52 drives the glue roller 7 to move along the slide rail 51 towards the connecting rod 31, ensuring the accuracy of the reciprocating movement of the glue roller 7 and preventing the glue roller 7 from being misaligned.

[0027] In this embodiment, please refer to Figure 1The slider 52 is rotatably mounted with a roller 521 on the side facing the connecting rod 31. The roller 521 rolls and abuts against the cam 32. The cooperation between the two can reduce friction so that the cam 32 can push the slider 52, thereby facilitating the movement of the rubber pressure roller 7.

[0028] Please see Figure 2 The reset assembly 4 includes a tension spring 41 and a mounting block 42. The mounting block 42 is fixedly mounted on the frame 1. One end of the tension spring 41 is connected to the mounting block 42, and the other end is connected to the slider 52. The length direction of the tension spring 41 is the same as the length direction of the slide rail 51. Due to the characteristics of the tension spring 41, it can automatically pull the slider 52 back, so that the slider 52 drives the rubber pressure roller 7 back to the initial position. The tension spring 41 has a simple structure and is easy to install and maintain.

[0029] In this embodiment, two reset components 4 and two guide components 5 are provided. The two guide components 5 are respectively connected to the two ends of the glue roller 7, and the two reset components 4 are respectively connected to the two guide components 5, so as to ensure that the two ends of the glue roller 7 can move synchronously, thereby ensuring that the pressure of the glue roller 7 is uniform and consistent when pressing glue at each position.

[0030] The drive assembly 2 includes a motor 21, a drive gear 22, and a driven gear 23. The stator of the motor 21 is mounted on the frame 1, and its rotor is connected to the drive gear 22. The drive gear 22 meshes with the driven gear 23, and the driven gear 23 is connected to the end of the connecting rod 31. The motor 21 drives the drive gear 22 to rotate, the drive gear 22 drives the driven gear 23 to rotate, and the driven gear 23 drives the connecting rod 31 to rotate. The gear transmission has low energy loss and is easy to arrange, which helps to reduce the size of the entire mechanism.

[0031] In this embodiment, the diameter of the driving gear 22 is smaller than the diameter of the driven gear 23. Due to the large gear ratio, the force is amplified for the first time. The diameter of the driven gear 23 is larger than the diameter of the cam 32. When rotating, the force of the cam 32 is greater than the force of the driven gear 23, which amplifies the force for the second time, so as to achieve a large pressure in a small space and a small stroke.

[0032] A limiting assembly 11 is provided on the frame 1. The limiting assembly 11 includes a bracket 111 and two limiting wheels 112, both mounted on the bracket 111. The bracket 111 is mounted on the frame 1, and the connecting rod 31 abuts between the two limiting wheels 112. The arrangement direction of the two limiting wheels 112 is parallel to the arrangement direction of the pressure roller 7 and the connecting rod 31, and the connecting rod 31 is located between the two limiting wheels 112. The limiting wheels 112 limit the rotation trajectory and position of the connecting rod 31 through lateral contact, ensuring stable operation within a specific range and preventing deviation.

[0033] A preferred embodiment of this utility model also provides an adhesive applicator, including a transmission mechanism and a cam-based intermittent adhesive pressing mechanism as described above. The transmission mechanism is used to transport the batteries to be adhesiveped to the adhesive roller 7 for adhesive pressing. The transmission mechanism transports the batteries at a uniform speed, and the batteries to be adhesiveped are evenly spaced on the transmission mechanism. Under the action of the cam 32, the adhesive pressing mechanism can perform adhesive pressing once at the same time interval to ensure the accuracy of adhesive pressing.

[0034] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
