Description

Technical Field

[0001] This utility model relates to the field of dispensing machine technology, specifically a multi-point automatic dispensing machine. Background Technology

[0002] In modern industrial production, dispensing technology is widely used in various fields such as electronic components, automotive parts, integrated circuits, semiconductor packaging, printed circuit boards, color LCD screens, electronic components (such as relays and speakers), and electronic parts. Traditional dispensing methods relied mainly on manual operation by workers. However, with the rapid development of automation technology, manual dispensing can no longer meet the needs of industrial production and is gradually being replaced by automatic dispensing machines. However, most existing automatic dispensing machines can only perform single-point operations, which to some extent limits the improvement of production efficiency and cannot meet the current industrial production sector's demand for efficient and precise dispensing.

[0003] Taking the existing patent technology with patent number 202122170149.2 as an example, this patent discloses an automatic dispensing machine with high processing efficiency and multi-point operation. Although this technology improves dispensing efficiency to a certain extent, its structure is relatively complex, and in actual operation, the clamping and movement of the workpiece still require additional operating steps. This not only increases the cumbersomeness of operation but may also lead to inaccurate dispensing positions, thus affecting product quality. In addition, the existing automatic dispensing machine has a slow glue drying speed during the dispensing process, requiring additional time to wait for the glue to dry naturally, which further reduces production efficiency.

One end of the spring abuts against the movable rod, and the other end of the spring abuts against the placement platform.

[0010] Optionally, the limiting assembly further includes a chain and multiple sprockets, the sprockets being respectively sleeved on the outer side wall of the upper end of the roller; each sprocket is arranged along the length direction of the bending plate, the chain is wrapped around the outer circumference of each sprocket, and the chain meshes with each sprocket; the upper end of one of the rollers passes through the bending plate, and a first gear is fixedly installed at the upper end of the roller.

[0011] Optionally, the driving component includes a first linkage assembly and a second linkage assembly. The first linkage assembly includes a guide rod and a fourth slider.

[0014] (III) Beneficial Effects

[0015] This utility model provides a multi-point automatic dispensing machine, which has the following beneficial effects:

[0016] 1. This utility model incorporates two limiting components that stably clamp the workpiece. Simultaneously, the dispensing machine in the dispensing unit moves vertically via a lead screw and a first slider, enabling precise multi-point dispensing of the workpiece. This design not only improves dispensing efficiency but also avoids the cumbersome operation of frequent workpiece movement required by traditional single-point dispensing machines, significantly enhancing automation. Specifically, when the motor's output shaft rotates clockwise, the mounting rod, driven by the lead screw and first slider, lowers the dispensing machine to the workpiece surface for dispensing. After dispensing, the motor's output shaft rotates counter-clockwise, causing the lead screw to raise the mounting rod. Simultaneously, through a one-way bearing and gear transmission, the roller rotates, moving the workpiece to the next dispensing position. This process is fully automated, requiring no manual intervention, greatly improving production efficiency and solving the problem of low dispensing efficiency in existing technologies.

[0017] 2. This utility model incorporates a drying component. A fan supplies air to the inner cavity of the bending plate through a connecting pipe, and then dries the glued areas on the workpiece through through holes in the roller. This design significantly accelerates the drying speed of the adhesive, reducing the time spent waiting for it to dry naturally, thereby further improving production efficiency. Specifically, the roller has a hollow interior with vent holes in its walls, allowing the airflow from the fan to evenly reach the glued areas on the workpiece. Compared to traditional methods relying on natural drying, this utility model's drying design enables the adhesive to cure rapidly in a short time, avoiding problems such as workpiece adhesion and adhesive dripping caused by delayed drying, thus significantly improving product quality. Simultaneously, the rapidly drying adhesive better maintains the accuracy and consistency of the dispensing, further optimizing the product's appearance and performance. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0028] Please see Figures 1 to 6 The present invention provides a technical solution: a multi-point automatic dispensing machine, comprising a housing 1, a placement platform 2, a clamping component, a dispensing component, and a driving component, wherein the placement platform 2 is fixedly installed inside the housing 1.

[0029] The clamping component includes two limiting components, which are respectively installed at both ends of the placement platform 2. The limiting components include a bending plate 3 and multiple rollers 4. The bending plate 3 is C-shaped and is slidably installed at the end of the placement platform 2. Each roller 4 is rotatably installed inside the bending plate 3 and is arranged along the length of the bending plate 3.

[0030] The main function of the bending plate 3 is to provide a sliding support structure for mounting and fixing the roller 4, and to clamp the workpiece. The C-shaped design allows the bending plate 3 to clamp the workpiece from both sides, while leaving sufficient space for the roller 4 to rotate. The main function of the roller 4 is to clamp and position the workpiece through contact with its side edges.

[0031] The dispensing component includes a mounting rod 9 and a dispensing machine 11. The dispensing machine 11 is fixedly mounted on the mounting rod 9 and is located above the placement table 2.

[0032] The mounting rod 9 is used to fix and support the dispensing machine 11, ensuring that the dispensing machine 11 can perform precise vertical lifting movements. The dispensing machine 11 is used to dispense adhesive onto workpieces placed on the placement table 2. The dispensing machine 11 includes, but is not limited to, the dispensing head described in Chinese patent application publication number CN216150264U. The dispensing machine 11 is typically equipped with a sophisticated control system and dispensing mechanism, capable of precisely controlling the drip position and dispensing volume of adhesive according to preset programs and parameters. During the dispensing process, the nozzle of the dispensing machine 11 is aligned with the dispensing position on the workpiece, and the adhesive is extruded from the nozzle by internal air pressure or mechanical drive, completing the dispensing operation. The dispensing machine 11 uses existing equipment on the market; its specific structure and working principle will not be elaborated further.

[0033] The driving component includes a motor 16, which is fixedly mounted on the outer wall of a bent plate 3. The motor 16 is connected to the mounting rod 9 in a transmission manner. When the output shaft of the motor 16 rotates clockwise, it drives the mounting rod 9 to move and descend.

[0034] The motor 16 is connected to each roller 4 in a limiting assembly. When the output shaft of the motor 16 rotates counterclockwise, the motor 16 drives the roller 4 to rotate, and the motor 16 also drives the mounting rod 9 to move and rise.

[0035] The motor 16 includes, but is not limited to, a servo motor or a stepper motor. The drive unit is the core component of this invention for controlling the lifting and lowering of the dispensing machine 11 and the movement of the workpiece. The motor 16 provides power. When dispensing is required, the output shaft of the motor 16 rotates clockwise, driving the mounting rod 9 to lower the dispensing machine 11 to the workpiece surface for dispensing. After dispensing, the output shaft of the motor 16 rotates counterclockwise, driving the roller 4 to rotate. Simultaneously, the lead screw 12 drives the first slider 10 to move upward, causing the mounting rod 9 and the dispensing machine 11 to rise and leave the workpiece surface. At the same time, when the output shaft of the motor 16 rotates counterclockwise, it drives the roller 4 to rotate. The rotation of the roller 4 moves the workpiece on the placement table 2, ensuring that the dispensing machine 11 can dispense glue to different positions on the workpiece.

[0036] Specifically, a multi-point automatic dispensing machine further includes a drying component, which includes a fan 8 and a connecting pipe 7. The fan 8 is fixedly installed on the outer wall of the housing 1. The inside of the bending plate 3 is hollow, and the inside of the roller 4 is hollow, with vent holes provided on the wall of the roller 4. The roller 4 is connected to the bending plate 3. One end of the connecting pipe 7 is fixedly installed and connected to the airflow outlet of the fan 8, and the other end of the connecting pipe 7 is fixedly installed and connected to the bending plate 3.

[0037] The rotation of roller 4 not only enables fine-tuning and movement of the workpiece, but also provides a channel for the drying function through the internal cavity and vent holes on the wall, accelerating the drying of the adhesive. Fan 8 supplies air to the inner cavity of bending plate 3 through connecting pipe 7. The airflow is evenly blown onto the adhesive application point of the workpiece through the through holes on roller 4, significantly accelerating the drying speed of the adhesive. Fan 8 serves as the air source, generating airflow.

[0038] Specifically, the limiting assembly also includes multiple movable rods 6 and multiple springs 19. The movable rods 6 are generally L-shaped, with one end fixedly connected to the bending plate 3 and the other end inserted into the end of the placement platform 2, and the movable rods 6 and the placement platform 2 are laterally slidably connected. The springs 19 are sleeved on the outer wall of the movable rods 6 and are located inside the placement platform 2. One end of the springs 19 abuts against the movable rods 6, and the other end of the springs 19 abuts against the placement platform 2.

[0039] The main function of the movable rod 6 is to connect the bending plate 3 and the placement table 2, and to enable the lateral sliding of the bending plate 3. The L-shaped design allows the movable rod 6 to slide stably at the end of the placement table 2, while also providing a mounting position for the spring 19. The main function of the spring 19 is to provide elastic force, enabling the bending plate 3 to automatically reset, thus clamping and releasing the workpiece. When a workpiece needs to be placed, the bending plate 3 is pulled by hand, the movable rod 6 slides along the end of the placement table 2, the spring 19 is compressed, and the bending plate 3 moves away from the placement table 2, opening the clamping space. When a workpiece needs to be removed, the bending plate 3 is pulled again, the movable rod 6 slides along the end of the placement table 2, the spring 19 is compressed, the bending plate 3 moves away from the placement table 2, the roller 4 leaves the workpiece, and the workpiece is released. The spring constant of spring 19 is precisely calculated to ensure that it provides sufficient clamping force when holding the workpiece, while avoiding damage to the workpiece.

[0040] More specifically, the limiting assembly also includes a chain 5 and multiple sprockets, each sprocket being sleeved on the outer wall of the upper end of the roller 4. The sprockets are arranged along the length of the bending plate 3, and the chain 5 is wound around the outer circumference of each sprocket, meshing with each sprocket. The upper end of one roller 4 passes through the bending plate 3, and a first gear 13 is fixedly installed at the upper end of this roller 4. A second gear 14 is installed at the output shaft end of the motor 16, and the second gear 14 meshes with the first gear 13.

[0041] Chain 5 and sprockets are used to transmit power, ensuring that all rollers 4 rotate synchronously. The meshing transmission between chain 5 and sprockets ensures efficient power transmission and synchronous rotation of multiple rollers 4. When the output shaft of motor 16 rotates counterclockwise, it drives the first gear 13 to rotate through the transmission of the second gear 14. The rotation of the first gear 13, through the transmission of the sprockets and chain 5, drives all rollers 4 in a limit assembly to rotate synchronously, thereby realizing the movement of the workpiece. This design not only improves transmission efficiency but also ensures the smoothness and accuracy of workpiece movement.

[0042] More specifically, the driving components include a first linkage assembly and a second linkage assembly. The first linkage assembly includes a guide rod and a fourth slider. The fourth slider is laterally slidably mounted on the inner top wall of the housing 1. The upper end of the guide rod is fixedly connected to the fourth slider, and the lower end of the guide rod is fixedly connected to a bending plate 3. The second linkage assembly includes a support plate 15, a lead screw 12, and a second slider 17. The support plate 15 is fixedly connected to the outer wall of the bending plate 3. The second slider 17 is laterally slidably mounted on the inner top wall of the housing 1. The upper and lower ends of the lead screw 12 are rotatably connected to the second slider 17 and the support plate 15, respectively. The motor 16 is driven by the lead screw 12.

[0043] The second linkage assembly also includes a one-way bearing 18 and a second gear 14. The one-way bearing 18 is mounted on the outer wall of the lead screw 12, and the second gear 14 is mounted on the outer wall of the one-way bearing 18. The inner ring of the one-way bearing 18 is fixedly connected to the lead screw 12, and the outer ring of the one-way bearing 18 is fixedly connected to the second gear 14. The second gear 14 meshes with the first gear 13.

[0044] In the first linkage assembly, the guide rod guides the lifting and lowering movement of the mounting rod 9, ensuring the smoothness and linearity of the movement. The fourth slider ensures that the guide rod can achieve lateral sliding displacement. In the second linkage assembly, the support plate 15 supports the lead screw 12, which converts the rotational motion of the motor 16 into the linear motion of the mounting rod 9, realizing the lifting and lowering of the dispensing machine 11. The second slider 17 ensures that the lead screw 12 can achieve lateral sliding displacement. The motor 16 drives the lead screw 12 to rotate, providing power support. The main function of the one-way bearing 18 is to allow the lead screw 12 to perform different functions when rotating clockwise and counterclockwise. Specifically, when the lead screw 12 rotates clockwise, the outer ring of the one-way bearing 18 remains stationary, allowing the lead screw 12 to drive the first slider 10 to descend through threaded transmission, thus lowering the dispensing machine 11. When the lead screw 12 rotates counterclockwise, the outer ring and inner ring of the one-way bearing 18 rotate together, driving the roller 4 to rotate through the second gear 14 and the first gear 13, thus moving the workpiece.

[0045] Motor 16, connected to lead screw 12, can drive lead screw 12 to rotate clockwise or counterclockwise. When the output shaft of motor 16 rotates clockwise, the mounting rod 9, driven by lead screw 12 and first slider 10, lowers the dispensing machine 11 to the workpiece surface for dispensing. When the output shaft of motor 16 rotates counterclockwise, the roller 4 rotates via one-way bearing 18 and gear transmission, simultaneously raising the mounting rod 9 and lifting the dispensing machine 11 away from the workpiece surface. This design not only achieves precise lifting and lowering of the dispensing machine 11 but also enables automatic movement of the workpiece, improving dispensing efficiency.

[0046] More specifically, the dispensing component also includes two first sliders 10, which are respectively fitted onto the outer walls of the lead screw 12 and the guide rod. One first slider 10 is threadedly connected to the lead screw 12, and the other first slider 10 is slidably connected to the guide rod. Furthermore, the two first sliders 10 are laterally slidably mounted at both ends of the rod 9.

[0047] The primary function of the first slider 10 is to convert the rotational motion of the lead screw 12 into the linear motion of the mounting rod 9, and to ensure the smoothness and linearity of the motion through the guide rod. When the motor 16 drives the lead screw 12 to rotate, the lead screw 12 drives the first slider 10 to move axially along the lead screw 12 through threaded transmission. This threaded connection ensures the accuracy and controllability of the motion. Simultaneously, the first slider 10 slides along the guide rod, ensuring that the mounting rod 9 maintains linear motion during lifting and lowering, preventing the mounting rod 9 from shifting or wobbling. The guide rod design provides stable support, ensuring smooth motion. The lateral sliding installation between the first slider 10 and the mounting rod 9 allows adjustment of the distance between the two first sliders 10. When manually adjusting the clamping distance between the two bending plates 3, the distance between the two first sliders 10 will also change accordingly. The lateral sliding installation between the first slider 10 and the mounting rod 9 ensures that the first slider 10 drives the mounting rod 9 to lift and lower without affecting the adjustment of the clamping distance between the two bending plates 3.

[0048] In use, manually pull the bending plate 3 to slide the movable rod 6 along the end of the placement table 2, compressing the spring 19 and opening the clamping space. Place the workpiece to be glued on the placement table 2, ensuring accurate workpiece positioning. Release the bending plate 3; the elasticity of the spring 19 returns the movable rod 6 to its original position, and the rollers 4 on the bending plate 3 contact the two edges of the workpiece, achieving workpiece clamping.

[0049] The motor 16 is started, and its output shaft rotates clockwise. The lead screw 12 drives the first slider 10, which is threadedly connected to the lead screw 12, to move downwards via a threaded transmission. The first slider 10, which is slidably connected to the guide rod, slides along the guide rod, ensuring the linear movement of the mounting rod 9. The mounting rod 9 drives the dispensing machine 11 to descend to the workpiece surface, and the dispensing operation begins.

[0050] The nozzle of the dispensing machine 11 is aligned with the dispensing position on the workpiece, and the glue is squeezed out from the nozzle to complete the dispensing operation.

[0051] After dispensing is completed, the output shaft of motor 16 rotates counterclockwise. The lead screw 12, via threaded transmission, drives the first slider 10, which is threadedly connected to the lead screw 12, to move upwards. The first slider 10, slidably connected to the guide rod, slides along the guide rod, ensuring the linear movement of the mounting rod 9. The mounting rod 9 drives the dispensing machine 11 to rise, leaving the workpiece surface.

[0052] The output shaft of motor 16 continues to rotate counterclockwise, driving the second gear 14 to rotate via the one-way bearing 18. The second gear 14 meshes with the first gear 13, driving the first gear 13 to rotate. The rotation of the first gear 13 drives all rollers 4 to rotate synchronously via the sprocket and chain 5. The rotation of the rollers 4 moves the workpiece on the placement table 2, ensuring that the dispensing machine 11 can dispense glue to different positions on the workpiece.

[0053] During the dispensing process, the blower 8 supplies air to the inner cavity of the bending plate 3 through the connecting pipe 7. The airflow is evenly blown onto the dispensing position of the workpiece through the through holes on the roller 4, accelerating the drying speed of the adhesive. The air-drying function ensures that the adhesive cures quickly in a short time, avoiding problems such as workpiece adhesion or adhesive dripping caused by untimely drying.

[0054] Based on the dispensing requirements of the workpiece, repeat the above dispensing and workpiece movement operations until dispensing at all positions is completed. After each dispensing operation, the output shaft of motor 16 rotates counterclockwise, driving roller 4 to rotate and moving the workpiece to the next dispensing position.
