Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electronic component processing, and particularly relates to a glue dispensing device for electronic components. Background Art
[0002] Electronic components, as the basic components of modern electronic equipment, their stability and reliability are crucial to the performance of the entire system. During the assembly process of electronic components, dispensing is widely used to fix components or circuit boards to adapt to vibrations during transportation and ensure the stability of the final installation. Dispensing technology is particularly important for vertical components that are heavy, easy to fall off, easy to swing, or large in size and have no external fixing method. During the dispensing process, special attention should be paid to the dispensing distance. For vertical components, the dispensing distance is usually greater than one-third of the component height and less than two-thirds; for horizontal components, it needs to be greater than two-thirds of the component length to ensure that the colloid can effectively fill the gap between the component and the circuit board.
[0003] However, existing dispensing technology faces a series of challenges in practical applications. First, the encapsulated colloid usually needs to be stored in a frozen state and needs to be placed in a heating barrel for thawing before use. The hot and cold shock during this process may cause bubbles to form inside the colloid. If not handled in time, it will cause breakpoints in the dispensing process, thereby affecting the packaging quality of electronic components. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] 1. The utility model realizes the effective discharge of air inside the colloid through the coordinated action of the motor, the connecting frame, the connecting rod and the vibrating rod.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The dispensing mechanism 4 is located above the operating table 1, the bubble removal mechanism 5 is located above the dispensing mechanism 4, and the collecting and sealing mechanism 6 is located between the dispensing mechanism 4 and the bubble removal mechanism 5; the bubble removal mechanism 5 is set up to quickly discharge the bubbles in the colloid inside the heating barrel 41 in the dispensing mechanism 4, and after the bubbles are discharged, the heating barrel 41 in the dispensing mechanism 4 is sealed by the collecting and sealing mechanism 6 to keep the interior clean, and at the same time, the colloid dripped by the bubble removal mechanism 5 can be collected, thereby solving the problem of bubbles forming inside the colloid during thawing and breakpoints occurring during dispensing.
[0024] In a further embodiment, referring to Figure 2-Figure 3 The dispensing mechanism 4 includes a heating barrel 41 and a dispensing head 43. The left end of the slider 3 is fixedly connected to the dispensing head 43 and the heating barrel 41 through a mounting block. The heating barrel 41 is located at the left end of the dispensing head 43. The lower end of the heating barrel 41 is fixedly connected to a connecting pipe 42. The end of the connecting pipe 42 away from the heating barrel 41 is fixedly connected to the side wall of the dispensing head 43.
[0025] In this embodiment, the frozen stored colloid is poured into the inner wall of the heating barrel 41 and thawed by the heating barrel 41 . The thawed colloid can continuously provide colloid to the dispensing head 43 .
[0026] In a further embodiment, referring to Figure 2-Figure 3 The bubble removal mechanism 5 includes a motor 53 and a vibrating rod 57. The left end of the slider 3 is fixedly connected to the electric telescopic rod 51 through the mounting block. The output shaft end of the electric telescopic rod 51 is fixedly connected to the lifting block 52. The left end of the lifting block 52 is fixedly connected to the motor 53. The output shaft end of the motor 53 is fixedly connected to the connecting frame 54. The lower end of the connecting frame 54 is fixedly connected to the connecting rod 55. The side walls of the connecting rod 55 are equidistantly fixedly connected with stirring blades 56. The stirring blades 56 abut against the inner wall of the heating barrel 41. The lower end of the connecting frame 54 is fixedly connected to the vibrating rod 57. The vibrating rod 57 is located between the connecting rod 55 and the axis of the output shaft of the motor 53.
[0027] In this embodiment, the electric telescopic rod 51 is started to drive the lifting block 52 to move downward, thereby driving the motor 53 to move downward, thereby driving the stirring blade 56 and the vibrating rod 57 to move into the heating barrel 41, and then the motor 53 is started to drive the connecting frame 54 to rotate slowly, thereby driving the vibration plate and the stirring blade 56 to move. At this time, the vibrating rod 57 is started, so that the bubbles inside the colloid are driven by the vibration of the vibrating rod 57 and the stirring blade 56 to move the colloid downward, further accelerating the bubbles inside the colloid to move upward and be released. This design cleverly solves the problem of bubble formation inside the colloid during the thawing process and avoids the phenomenon of breakpoints during the dispensing process.
[0028] In a further embodiment, referring to Figure 3-Figure 5 The collecting and sealing mechanism 6 includes a sleeve 62 and a cover plate 63. The left end of the slider 3 is rotatably connected to the sleeve 62 through the bearing seat 61. The side wall of the sleeve 62 is fixedly connected to the cover plate 63. The upper end surface of the cover plate 63 is provided with a collecting groove 631. The lower end of the lifting block 52 is fixedly connected to the driving rod 7.

The limiting block 621 is located inside the first limiting groove 71 and is slidably connected with it.
[0029] In this embodiment, after the colloid bubbles are discharged, the electric telescopic rod 51 is started to drive the lifting block 52 to move upward, thereby driving the driving rod 7 to move downward. When the limit block 621 moves to the connection between the limit arc groove 72 and the first limit groove 71, the driving rod 7 continues to move upward, so that the limit block 621 drives the sleeve 62 to rotate under the restriction of the limit arc groove 72, thereby driving the cover plate 63 to rotate. When the limit block 621 moves to the connection between the limit arc groove 72 and the second limit groove 73, the cover plate 63 just moves to the top of the heating barrel 41, thereby keeping the inner wall of the heating barrel 41 clean. When the limit block 621 moves to the connection between the limit arc groove 72 and the first limit groove 71, the vibrating rod 57 and the connecting rod 55 move to the top of the heating barrel 41. When the cover plate 63 moves to the top of the heating barrel 41, the colloid dripping from the stirring blade 56, the vibrating rod 57 and the connecting rod 55 can be collected through the collecting groove 631 opened at the upper end of the cover plate 63, thereby realizing dual functions.
