Description

Technical Field

[0001] This utility model relates to the field of automation control technology, and in particular to an automatic dispensing machine for loading and unloading materials. Background Technology

[0002] A dispensing machine (also known as an adhesive applicator or glue applicator) is an industrial device that uses an automated system to precisely control the distribution of liquids (such as adhesives, inks, lubricants, etc.). It is widely used in electronics manufacturing, the automotive industry, and medical device assembly, and is particularly suitable for processes requiring stringent precision and consistency in adhesive application. Currently, semi-automatic dispensing machines still rely on manual loading and unloading operations. Processing efficiency is directly affected by the worker's skill level and work condition. Prolonged repetitive work can easily lead to operator fatigue, resulting in efficiency fluctuations and uneven adhesive application.

[0003] Therefore, there is a particular need for an automatic dispensing machine with loading and unloading capabilities to solve the above problems. Utility Model Content

[0004] To overcome the shortcomings of semi-automatic dispensing machines that rely on manual loading and unloading, resulting in processing efficiency being affected by the skill level and fatigue of employees, and easily leading to efficiency fluctuations and uneven glue application, this utility model provides an automatic loading and unloading dispensing machine.

[0005] This utility model is achieved through the following technical means: an automatic dispensing machine for loading and unloading materials includes a base, a glue storage tank, a water pump, a glue delivery pipe, a dispensing head, a worktable, a motor, a support frame, a first electric push rod, a cross suction cup frame, and a controller. The glue storage tank is fixedly connected to the rear top of the base, and a glue inlet is opened on the glue storage tank. The water pump is fixedly connected to the top of the glue storage tank, and a glue delivery pipe is fixedly connected to the output end of the water pump. A dispensing head is fixedly connected to the other end of the glue delivery pipe. The worktable is fixedly connected to the front top of the base, and the rear side wall of the worktable is fixedly connected to the front side wall of the glue storage tank. The motor is fixedly connected to the front side wall of the base, and a support frame is sleeved and fixedly connected to the output shaft of the motor. The first electric push rod is fixedly connected to the support frame and rotatably connected to the front side of the worktable. A cross suction cup frame is fixedly connected to the piston rod of the first electric push rod. The controller is fixedly connected to the left side of the top of the base. The water pump, dispensing head, motor, and first electric push rod are all electrically connected to the controller.

[0006] Furthermore, the loading mechanism includes a loading frame, a second electric push rod, and a first support plate. The loading frame is fixedly connected to the left side of the front side wall of the base, and the second electric push rod is fixedly connected to the front side wall of the loading frame. The second electric push rod is electrically connected to the controller, and the first support plate is fixedly connected to the piston rod of the second electric push rod. The first support plate is slidably connected inside the loading frame.

[0007] Furthermore, the material handling mechanism includes a material handling frame, a second support plate, and springs. The material handling frame is fixedly connected to the right side of the front side wall of the base. A material handling port is opened on the lower side of the material handling frame. The second support plate is slidably connected to the material handling frame. Symmetrical springs are connected between the bottom of the second support plate and the lower side of the material handling frame.

[0008] Furthermore, the remaining quantity detection mechanism includes a fixed rod, a float, a sensing module, and an alarm. The left side of the inside of the glue storage tank is fixed with symmetrical fixed rods, and a float is slidably connected between the two fixed rods. A sensing module is fixed to the right side wall of the float, and a sensing module is also fixed to the lower left side wall of the glue storage tank. An alarm is fixed to the front of the top of the glue storage tank. Both the alarm and the sensing module are electrically connected to the controller.

[0009] Furthermore, the base has symmetrical support feet at the bottom.

[0010] Furthermore, the top of the second support plate is coated with an anti-slip adhesive coating.

[0011] As can be seen from the above description of the structure of this utility model, the design starting point, concept and advantages of this utility model are: 1. This utility model uses components such as electric push rod, support frame and cross suction cup frame to replace manual operation, realize automated loading and unloading, eliminate the problems of efficiency fluctuation and uneven glue amount caused by differences in employee proficiency or fatigue, and ensure stable production rhythm and consistent glue application accuracy.

[0012] 2. This utility model uses a spring-buffered material handling frame design, which allows finished workpieces to be continuously piled up and easily removed; and the float, sensing module and alarm monitor the amount of adhesive in real time and alarm at the critical point to avoid production interruption and improve the continuous operation capability of the equipment.

[0013] 3. This utility model, through its adjustable height first support plate and adaptive adsorption cross suction cup frame, can accommodate workpieces of different sizes, eliminating the need for frequent fixture changes and reducing changeover time and manual intervention requirements.

[0014] 4. This utility model prevents workpieces from adhering to the cross suction cup frame through the anti-slip adhesive coating of the second support plate, reduces the risk of operational errors through the sensing module, and ensures the reliability of the process through the closed-loop control of the overall mechanism.

Figures 1-6 As shown, the system includes a base 1, a glue storage tank 2, a water pump 4, a glue delivery pipe 3, a dispensing head 5, a worktable 6, a motor 7, a support frame 701, a first electric push rod 8, a cross suction cup frame 9, and a controller 10. Symmetrical support feet are welded to the bottom of the base 1 to ensure stability. The glue storage tank 2 is welded to the rear top of the base 1, and a glue inlet 201 is provided on the tank 2. The water pump 4 is bolted to the top of the tank 2, and the glue delivery pipe 3 is fixedly connected to the output end of the water pump 4. The dispensing head 5 is fixedly connected to the other end of the glue delivery pipe 3. A worktable is bolted to the front top of the base 1. The worktable 6 is bolted to the front wall of the glue storage tank 2. The front wall of the base 1 is bolted to the motor 7. The output shaft of the motor 7 is fitted with a support frame 701. The support frame 701 is fixedly connected to the first electric push rod 8. The first electric push rod 8 is rotatably connected to the front of the worktable 6. The piston rod of the first electric push rod 8 is fixedly connected to a cross suction cup 9 for adsorbing and transferring workpieces. The top left side of the base 1 is bolted to the controller 10. The water pump 4, the glue dispensing head 5, the motor 7 and the first electric push rod 8 are all electrically connected to the controller 10.

[0023] like Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the loading mechanism includes a loading frame 11, a second electric push rod 12, and a first support plate 13. The loading frame 11 is bolted to the left side of the front side wall of the base 1. The second electric push rod 12 is bolted to the front side wall of the loading frame 11. The second electric push rod 12 is electrically connected to the controller 10. The first support plate 13 is fixedly connected to the piston rod of the second electric push rod 12. The first support plate 13 is slidably connected to the inside of the loading frame 11.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, the material handling mechanism includes a material handling frame 14, a second support plate 15, and a spring 16. The material handling frame 14 is bolted to the right side of the front side wall of the base 1. A material handling port 1401 is opened on the lower side of the material handling frame 14. The second support plate 15 is slidably connected to the material handling frame 14. The top of the second support plate 15 is coated with an anti-slip adhesive coating. The bottom of the second support plate 15 and the lower side of the material handling frame 14 are connected by left and right symmetrical springs 16.

[0025] like Figure 1 , Figure 5 and Figure 6 As shown, the remaining quantity detection mechanism includes a fixed rod 17, a float 18, a sensing module 19, and an alarm 20. The left side of the inside of the glue storage tank 2 is welded with symmetrical fixed rods 17. The float 18 is slidably connected between the two fixed rods 17. The sensing module 19 is bolted to the right side wall of the float 18. The sensing module 19 is also bolted to the lower left side wall of the glue storage tank 2. The alarm 20 is bolted to the front top of the glue storage tank 2. Both the alarm 20 and the sensing module 19 are electrically connected to the controller 10.

[0026] When a workpiece needs to be glued, first place the base 1 on a horizontal table, and place the workpiece to be processed into the loading frame 11. Then, start the second electric push rod 12 via the controller 10. The piston rod of the second electric push rod 12 pushes the first support plate 13 upward within the loading frame 11, lifting the workpiece to be processed to a predetermined height. Next, start the motor 7 via the controller 10. The output shaft of the motor 7 drives the support frame 701 to rotate, causing one side of the cross suction cup frame 9 to move above the loading frame 11. Then, start the first electric push rod 8 via the controller 10, controlling the piston rod of the first electric push rod 8 to move downward. After the suction cup on the cross suction cup frame 9 adsorbs the workpiece to be processed, control the piston rod of the first electric push rod 8 to move upward, controlling the output shaft of the motor 7 to continue driving the cross suction cup frame 9 to rotate, transferring the workpiece to be processed onto the worktable 6. Then, start the water pump 4 via the controller 10, and transport the glue in the glue storage tank 2 to the dispensing head 5 through the glue delivery pipe 3. The device 10 starts the dispensing head 5 and completes the glue application according to the preset glue amount. After the glue application is completed, the cross suction cup frame 9 re-adsorbs the processed workpiece. The output shaft of the control motor 7 continues to rotate and move the workpiece above the picking frame 14. The first electric push rod 8 is controlled to move downward. After the processed workpiece contacts the second support plate 15, the suction cup on the cross suction cup frame 9 releases the processed workpiece because the top of the second support plate 15 is coated with an anti-slip adhesive coating. As the number of processed workpieces increases, the second support plate 15 gradually presses down the spring 16 due to the load until it reaches the picking port 1401. The operator can then take out the processed workpiece. The float 18 in the glue storage tank 2 moves downward along the fixed rod 17 as the glue level drops. When the glue is about to run out, the sensing module 19 on the float 18 is aligned with the sensing module 19 on the glue storage tank 2 and sends a signal to the controller. The controller triggers the alarm 20 to remind the operator to add glue. The operator can then add glue through the glue inlet 201.
