Description
Technical Field
[0001] This application relates to the field of adhesive application equipment technology, and in particular to an automatic adhesive application module. Background Technology
[0002] Adhesive application equipment is used to replace manual application of adhesive to product surfaces, thereby bonding products and parts together. An adhesive application module is a device that continuously dispenses adhesive and creates long strips of adhesive. It can be used in chip packaging for adhesive application processes, primarily for bonding, sealing, reinforcing, and waterproofing chips. It can also be used for other products requiring adhesive application.
[0003] Utility model patent with announcement number CN222260981U discloses a dotting adhesive execution unit and a dotting adhesive device for a chip substrate. The dotting adhesive execution unit for the chip substrate includes a support platform and a dotting adhesive head, with the dotting adhesive head mounted on the support platform. A linear drive module is mounted on the support platform. A longitudinal drive is provided on the base, which is used to drive the gantry to move along the base. A transverse drive is mounted on the beam, which is used to drive the dotting adhesive execution unit to move along the beam.
[0004] Regarding the aforementioned technologies, with improvements in processes and structures, the size and weight of the actuators used for gluing are increasing. Using a single linear module for driving results in slow acceleration and response. Furthermore, the aforementioned equipment cannot perform dual-station gluing, leading to insufficient work efficiency. Summary of the Invention
[0005] This application provides an automatic glue application module, which uses dual linear motors to drive the movement of a single-sided slide, resulting in fast acceleration and response. The dual slides combined with two sets of glue application actuators enable dual-station operation, thereby improving work efficiency.
[0006] This application provides an automatic glue-applying module, which adopts the following technical solution: An automatic glue-applying module includes a base, on which two sets of linear motors are fixed. Each linear motor includes a stator and two movers. The two sets of linear motors are symmetrically arranged front and back. A second linear motor is fixed between the two movers. There are two sets of second linear motors, each including a stator and a mover. Both linear motors are flat. A slide is fixed to the mover. A glue-applying mechanism is mounted on the slide via a linear motor. The glue-applying mechanism includes a fixed base and a glue cylinder. A glue dispensing head is inserted into the bottom end of the glue cylinder.
[0007] By adopting the above technical solution, two motors simultaneously drive linear motor 2 to move left and right, thereby moving the corresponding slide block left and right. This provides greater power and acceleration, enabling rapid response in the left and right movement of the slide block. Using dual linear motors to drive the movement of a single slide block results in fast acceleration and response. The combination of dual slide blocks and two sets of adhesive application mechanisms enables dual-station operation, improving work efficiency.
[0008] Optionally, the third linear motor is a rod type, with the rod of the third linear motor arranged vertically, and the sliding directions of the first linear motor, the second linear motor, and the third linear motor are perpendicular to each other to form a three-axis movement system.
[0009] By adopting the above technical solution, the position of the adhesive dispensing in three-dimensional space can be adjusted in all directions.
[0010] Optionally, the camera is fixed to the mounting base, the camera is positioned downwards, and the rubber tube is positioned close to the camera.
[0011] By adopting the above technical solution, the image captured by the camera is used by the image recognition system in the controller to identify the position where glue needs to be applied. After the slide is offset by a fixed distance in the front and back directions, it can correspond to the glue dispensing position of the glue head, thereby realizing the operation of automatic identification and automatic positioning of glue application.
[0012] Optionally, the top of the rubber tube is open, and a liquid level sensor is installed on the fixing base. The liquid level sensor corresponds to the lower middle part of the rubber tube, and the liquid level sensor is non-contact and located outside the rubber tube.
[0013] By adopting the above technical solution, when the amount of glue in the glue tube is low, the liquid level sensor detects this and feeds back to the control system to remind the staff; a non-contact liquid level sensor is used to avoid contact with the glue.
[0014] Optionally, the fixed base is rotatably mounted with a swing arm, and a servo electric cylinder is mounted on the swing arm. A cover cylinder is driven to rise and fall by the servo electric cylinder, and a sealing plate is provided inside the cover cylinder.
[0015] By adopting the above technical solution, after the cover is lowered to the bottom and inserted into the annular groove, the upper space inside the glue tube can be sealed to prevent glue from dispensing. After the cover is moved upward, the space inside the glue tube can be connected to the external atmospheric pressure, thereby realizing gravity-based glue dispensing. Combined with the displacement of the fixed base, the dispensing head moves on the workpiece to realize the glue application operation. By using a rotatable swing arm to rotate the cover away from the glue tube, it is easy to replace the glue tube.
[0016] Optionally, the top surface of the rubber tube is provided with an annular groove, which surrounds the outside of the top opening of the rubber tube, and a sealing gasket is fixed at the bottom end of the cover tube, with the annular groove used for embedding the sealing gasket.
[0017] By adopting the above technical solution, the sealing performance after the cover and the top surface of the glue tube are pressed together is improved, and the cover will not come into contact with the glue, eliminating the need for cleaning.
[0018] Optionally, a second servo electric cylinder is installed on the swing arm, and a connecting rod is fixed to the drive end of the second servo electric cylinder, and the connecting rod is fixed to the sealing plate.
[0019] By adopting the above technical solution, the sealing plate is raised and lowered by the extension and retraction of the servo electric cylinder 2. When it is necessary to pause the glue dispensing, the cover cylinder moves down to the bottom and inserts into the annular groove, while the sealing plate is moved up slightly. This reduces the air pressure inside the glue cylinder, thereby stopping the glue dispensing. The liquid level at the bottom of the glue rises slightly, thus reliably stopping the glue dispensing and preventing accidental glue dripping.
[0020] Optionally, the sealing plate is slidably disposed inside the cover cylinder, and a sealing ring is fixed to the outer wall of the sealing plate.
[0021] By adopting the above technical solution, the sealing performance of the sliding between the sealing plate and the cover cylinder is improved.
[0022] Optionally, the fixed base is provided with a spring clip, and the surface of the swing arm is provided with a slot for the spring clip to be inserted.
[0023] By adopting the above technical solution, when the swing arm rotates to the position of the cover directly above the rubber tube, the spring buckle engages with the slot, which limits the swing arm and prevents it from rotating spontaneously.
[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The system uses dual linear motors to drive the movement of a single-sided slide, resulting in fast acceleration, quick response, and better support and sliding guidance. The dual slides combined with two sets of adhesive application actuators enable dual-station operation, improving work efficiency. 2. An independently sliding sealing plate is installed, which can reliably stop the glue and prevent accidental glue dripping. 3. The cover and sealing plate never come into contact with the glue, so there is no need for cleaning, and there is no problem of the glue being difficult to clean after it has solidified; when personnel change the glue tube, their hands are less likely to come into contact with glue, resulting in a better experience.

[0027] The present application will be further described in detail below with reference to the accompanying drawings.
[0028] Reference Figure 1 and Figure 2 This embodiment discloses an automatic glue application module, including a base 1. Two linear motors 2 are fixed to the base 1. Each linear motor 2 includes a stator 21 and two movers 22. The two linear motors 2 are symmetrically arranged front and rear. A linear motor 3 is fixed between the two movers 22. There are two sets of linear motors 3, each including a stator 31 and a mover 32. The linear motors 3 are fixed to the two movers 22 via the stator 31. Both linear motors 2 and 3 are flat; linear motor 2 is horizontally mounted, and linear motor 3 is vertically mounted. A slide 4 is fixed to the mover 32. A glue application mechanism is mounted on the slide 4 via a linear motor 41. The glue application mechanism includes a fixed base 5 and a glue cylinder 6. A glue dispensing head 61 is inserted into the bottom end of the glue cylinder 6.
[0029] The two motors, front and rear, move synchronously via a circuit configuration, always maintaining symmetry. Simultaneously, the two motors drive the linear motor 3 to move left and right, thereby moving the corresponding slide 4 left and right. This provides greater power and acceleration, enabling the slide 4 to respond quickly to left and right movements.
[0030] Linear motor 3 (41) is a round rod type, with its round rod positioned vertically. The sliding directions of linear motors 1 (2), 2 (3), and 3 (41) are perpendicular to each other, forming a three-axis movement system that enables omnidirectional adjustment of the glue dispensing position in three-dimensional space. Since there are two sets of linear motors 2 (3), slide 4, and glue dispensing actuators, dual-station glue dispensing is achieved, improving efficiency. The two sets of glue dispensing actuators can be controlled to operate independently, enhancing flexibility.
[0031] Reference Figure 3 A camera 51 is fixed to the mounting base 5, with the camera 51 facing downwards and the glue tube 6 positioned close to the camera 51. The image captured by the camera 51 is processed by the image recognition system within the controller to identify the location where glue needs to be applied. After the slide 4 is offset by a fixed distance in the front-back direction, it corresponds to the glue dispensing position of the glue head 61, thereby achieving automatic identification and automatic positioning for glue application.
[0032] The glue cartridge 6 is fixed to the mounting base 5 by a clamp. The glue cartridge 6 and the glue inside are independent consumables. The glue cartridge 6 is the packaging container for the glue; it is disposable after use, and then replaced with a new one. The glue cartridge 6 is made of transparent or semi-transparent plastic, with an open top. A liquid level sensor 52 is installed on the mounting base 5, corresponding to the lower middle part of the glue cartridge 6. The liquid level sensor 52 is non-contact and located outside the glue cartridge 6. When the glue volume in the glue cartridge 6 is low, the liquid level sensor 52 detects this and sends feedback to the control system to alert the operator. An electric heating wire is also installed inside the mounting base 5 near the glue cartridge 6 to heat the glue in the lower part of the cartridge 6, reducing the glue viscosity and ensuring smooth dispensing.
[0033] Reference Figure 4 , Figure 5 and Figure 6 A swing arm 7 is rotatably mounted on a fixed base 5. A servo cylinder 81 is mounted on the swing arm 7, and a cover 8 is driven to rise and fall by the servo cylinder 81. A sealing plate 9 is installed inside the cover 8. The cover 8 is raised and lowered by the extension and retraction of the servo cylinder 81. The sealing plate 9 is slidably disposed inside the cover 8, and a sealing ring 92 is fixed to the outer wall of the sealing plate 9. A second servo cylinder 91 is mounted on the swing arm 7. A connecting rod 93 is fixed to the drive end of the second servo cylinder 91. The connecting rod 93 is fixed to the sealing plate 9. The sealing plate 9 is raised and lowered by the extension and retraction of the second servo cylinder 91.
[0034] The top surface of the glue tube 6 is provided with an annular groove 62, which surrounds the outside of the top opening of the glue tube 6. A sealing gasket 82 is fixed at the bottom end of the cover tube 8, and the annular groove 62 is used for the sealing gasket 82 to be inserted. After the cover tube 8 moves down to the bottom end and inserts into the annular groove 62, the upper space inside the glue tube 6 can be sealed to prevent glue from leaking out. At this time, the up and down movement of the sealing plate 9 can drive the glue to move.
[0035] The fixed base 5 is provided with a spring clip 53, and the surface of the swing arm 7 is provided with a groove 71 for the spring clip 53 to be inserted. When the swing arm 7 rotates to the position of the cover 8 directly above the rubber tube 6, the spring clip 53 is engaged in the groove 71, which limits the swing arm 7 and prevents the swing arm 7 from rotating on its own.
[0036] The implementation principle of an automatic glue application module according to an embodiment of this application is as follows: a dual linear motor 2 drives a single-sided slide 4 to move, which accelerates quickly and responds quickly. The dual slide 4 is combined with two sets of glue application actuators to realize dual-station operation and improve work efficiency.
[0037] After rotating the swing arm 7 outward, the cover 8 is moved away from the top of the glue tube 6, and the glue tube 6 can be replaced. First, remove the top seal of the glue tube 6 to open its upper end, then move the swing arm 7 back and lower the height of the cover 8 so that the bottom end is inserted into the annular groove 62. Then remove the bottom seal of the glue tube 6 and replace it with the glue dispensing head 61. At this time, the glue tube 6 will not dispense glue.
[0038] When glue needs to be dispensed, the control sleeve 8 moves upward, which connects the space inside the glue cylinder 6 with the external atmospheric pressure, thereby realizing gravity-driven glue dispensing. Combined with the displacement of the fixed seat 5, the glue dispensing head 61 moves on the workpiece to realize the glue application operation. The glue used is a low-viscosity type, which makes the glue dispensing smooth.
[0039] When it is necessary to pause the dispensing of glue, the cover 8 is lowered to the bottom and inserted into the annular groove 62. At the same time, the sealing plate 9 is moved up slightly, which reduces the air pressure inside the glue tube 6, thereby stopping the dispensing of glue. The liquid level at the bottom of the glue moves up slightly, thus reliably stopping the glue and preventing accidental glue dripping.
[0040] When the glue content in the glue cylinder 6 decreases significantly, the glue dispensing speed slows down by gravity. The liquid level sensor 52 detects the glue level. At this time, the cover cylinder 8 is lowered, and then the air in the glue cylinder 6 is squeezed by the sealing plate 9 being lowered slowly to compensate for the glue dispensing speed.
[0041] The cover 8 and sealing plate 9 never come into contact with the glue, so there is no need to clean them, and there is no problem of the glue being difficult to clean after it has solidified; when personnel change the glue tube 6, their hands are less likely to come into contact with the glue, resulting in a better experience.
[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
