For this application, the corresponding positioning and adjustment fixing plate cannot be disassembled and replaced. When we need to perform dispensing operations on some special-shaped circuit boards, the ordinary clamping plate cannot play a role, so that the equipment cannot process special-shaped circuit boards, thereby limiting the scope of application of the equipment.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-3 The utility model provides an embodiment: a high-precision dispensing device for electronic components, including a base cabinet 1, a motor 2 is arranged on one side of the base cabinet 1, a threaded column 3 is fixedly connected to the output end of the motor 2, the threaded column 3 is rotatably connected to the inside of the base cabinet 1, the outer wall of the threaded column 3 is threadedly connected to a connecting plate 4, the connecting plate 4 is internally slidably connected to a limiting column 5, the limiting column 5 is fixedly connected to the inside of the base cabinet 1, the connecting plate 4 is internally slidably connected to a connecting column 6, the outer wall of the connecting column 6 is fixedly connected to a clamping plate 7, and the connecting column 6 is internally fixedly connected to a fixed column 8 The outer wall of the fixed column 8 is sleeved with a spring 9, one end of the spring 9 is fixedly connected to the inside of the connecting column 6, and the other end of the spring 9 is fixedly connected to a sliding column 10, which is slidably connected to the outer wall of the fixed column 8, and a ball 12 is arranged on the side of the sliding column 10 away from the spring 9, and both sides of the sliding column 10 are provided with a limit assembly, and the limit assembly includes a limit block 11 and a spacer 13, one side of the limit block 11 is fitted with one side of the spacer 13, the limit block 11 is slidably connected to the inside of the connecting column 6, and the spacer 13 is fixedly connected to the inside of the connecting column 6;

[0031] Specifically, when the clamping plate 7 needs to be replaced or maintained, the clamping plate 7 is first pulled away from the position of the connecting plate 4 through the connecting column 6. This action triggers the ball 12 to be squeezed and begins to compress the spring 9. When the spring 9 is compressed, the sliding column 10 is also subjected to corresponding pressure. In this process, the sliding column 10 is restricted by the spacer 13 and the fixed column 8, thereby accurately compressing the spring 9. The purpose of this design is to ensure that the ball 12 does not hinder the normal detachment of the connecting column 6. When the new clamping plate 7 is installed, the connecting column 6 Re-insert it into the connecting plate 4. At this time, the ball 12 is squeezed again and continues to compress the spring 9. When the ball 12 coincides with the reserved hole in the connecting plate 4, the spring 9 generates elastic potential energy through its own restorability. This elastic potential energy is transmitted through the sliding column 10, popping out the ball 12 and snapping it into the reserved hole in the connecting plate 4. At this time, the motor 2 is started to drive the threaded column 3 to rotate, and the threaded column 3 drives the connecting plate 4 and the clamping plate 7 to move under the restriction of the limit column 5, so as to accurately position and clamp the circuit board placed on the surface of the base cabinet 1.

[0032] Reference Figure 1-2and 4, a displacement cabinet 14 is fixedly connected to one side of the upper surface of the bottom cabinet 1, a fixed frame 15 is fixedly connected to one side of the displacement cabinet 14, a cylinder 16 is arranged inside the fixed frame 15, an output end of the cylinder 16 passes through the displacement cabinet 14 and is fixedly connected to a push rod 17, one end of the push rod 17 is fixedly connected to a dispensing disk 18, and a dispensing head 19 is arranged at the bottom of the dispensing disk 18;

[0033] Specifically, starting the air cylinder 16 can cause the corresponding push rod 17 to be pushed to move, thereby driving the dispensing plate 18 and the dispensing head 19 to move synchronously, so that dispensing operations at different positions can be performed.

[0034] Reference Figure 2 and 4 The outer wall of the dispensing plate 18 is fixedly connected with a fixing ring 20, and a sliding column 21 is slidably connected inside the fixing ring 20. The outer wall of the sliding column 21 is sleeved with a spring 22. One end of the spring 22 is fixedly connected to the outer wall of the fixing ring 20, and the other end of the spring 22 is fixedly connected to a push-pull plate 23. The bottom of the push-pull plate 23 is fixedly connected with a blade 24, and the blade 24 is slidably connected to the inside of the fixing ring 20;

[0035] Specifically, by pushing the push-pull plate 23, the blade 24 is pushed to slide under the restriction of the sliding column 21, so that the excess colloid at the position of the dispensing head 19 can be accurately cut off. This process is very efficient and does not hinder the dispensing operation of the dispensing head 19. When the blade 24 completes the cutting work, the push-pull plate 23 is released, and the spring 22 will push the push-pull plate 23 and the blade 24 back to the original position through the reaction force. This design not only ensures the ease of operation, but also effectively avoids the interference of the blade 24 with the operation of the dispensing head 19.

[0036] Working principle: When processing special-shaped circuit boards, we first use the connecting column 6 to pull the clamping plate 7 out of the position of the connecting plate 4, so that the ball 12 is first subjected to force and squeezed. At this time, the sliding column 10 will also be subjected to force, thereby compressing the spring 9 under the restriction of the spacer 13 and the fixed column 8, so that the corresponding ball 12 will not hinder the normal separation of the connecting column 6, so that the clamping plate 7 can also be separated normally. At this time, the new clamping plate 7 is installed, and the corresponding connecting column 6 will still be inserted into the connecting plate 4. The ball 12 is first subjected to force and then compresses the spring 9. When the ball 12 coincides with the reserved hole in the connecting plate 4, the corresponding ball 12 can be elastically generated by the spring 9 through its own restorative potential energy, and then ejected through the sliding column 10 and snapped into the reserved hole in the connecting plate 4. At this time, the motor 2 is started again to make The motor 2 drives the threaded column 3 to rotate, so that the threaded column 3 can drive the connecting plate 4 and the clamping plate 7 to move under the restriction of the limit column 5, so as to position and clamp the circuit board placed on the surface of the base cabinet 1. When glue is needed, the cylinder 16 is started at this time, so that the cylinder 16 pushes the push rod 17 to move left and right, so as to glue the circuit board. After a period of operation, in order to prevent a large amount of excess colloid from remaining at the position of the glue head 19, the push-pull plate 23 can be pushed to push the blade 24 to slide under the restriction of the sliding column 21, so as to cut off the excess colloid at the position of the glue head 19. After the corresponding cutting, only the push-pull plate 23 needs to be released, and the spring 22 will push the push-pull plate 23 and the blade 24 back to the original position through the reaction force, so as to prevent the blade 24 from hindering the glue dispensing operation of the glue head 19.
