[0032] The utility model provides a vibration table 1.

[0033] In the embodiment of the present utility model, Figures 1 to 3 As shown, the vibration table 1 includes a box body 10, a vibrating member 20, a connecting plate 30 and an electronic control device; the box body 10 is formed with a vibration groove 11; the fixed end of the vibrating member 20 is connected to the vibration groove 11; the connecting plate 30 is connected to the vibration end of the vibrating member 20 and is spaced apart from the box body 10, and the connecting plate 30 is used to place the product; the electronic control device is a programmable control device, and the electronic control device is electrically connected to the vibrating member 20 to control the opening or closing of the vibrating member 20 at different positions, so that different positions of the connecting plate 30 vibrate and drive the product to vibrate.

[0034] In this embodiment, the vibration table 1 includes a box body 10, and a vibration groove 11 is formed in the box body 10. The cross-sectional shape of the vibration groove 11 can be circular, rectangular, square, etc., which is not limited here. The vibration table 1 also includes a vibrating member 20 and a connecting plate 30. The number of the vibrating members 20 can be 1, 2, 3, 4, 5, etc., which is not limited here. When the number of the vibrating member 20 is one, the vibrating member 20 can be completely filled in the vibration groove 11, covering the area of ​​the entire connecting plate 30, and the vibration of different positions inside a vibrating member 20 can be transmitted to different positions of the connecting plate 30, changing the vibration of different positions of the connecting plate 30, and then transmitting to the product through the connecting plate 30. When the number of the vibrating members 20 is two or more, the multiple vibrating members 20 can be arranged in a straight line, or in an array, or can be arranged in an irregular shape according to the shape of the connecting plate 30, which is not limited here.

[0035] The vibration table 1 also includes an electronic control device, and the vibration elements 20 are all electrically connected to the electronic control device, so that the electronic control device can control one or more vibration elements 20, and further control the opening and closing, the amount of power supplied, the power supply time, etc. of one or more vibration elements 20, thereby changing the vibration amount or vibration duration of different vibration elements 20.

[0036] Furthermore, the electronic control device is a programmable control device, which can match the vibration parameters of different vibrators 20 by inputting different injection port parameters, product models, product types and other data, and can also adjust the vibration parameters of different vibrators 20 by inputting different injection port parameters, injection amount, injection flow rate, injection method and other data in advance. It can also adjust the vibration parameters of different vibrators 20 in real time during the vibration process, and the vibration parameters include vibration amplitude, vibration frequency, vibration action and action duration. Further, the electronic control device can also automatically identify the flow path and flow direction of the colloid through software intelligent control, and automatically adjust the vibration parameters of different vibrators 20. By synchronously controlling and adjusting the vibrators 20 at multiple different positions through the electronic control device, the flow direction and flow speed of the colloid in the product can be controlled to achieve different injection requirements; for example, the injection colloid is offset left and right, and the colloid can be controlled to flow left and right, and the vibrator 20 can be fully utilized to selectively adjust the flow direction of the colloid, and the colloid can be quickly transferred to fill the entire surface of the product, thereby increasing the injection speed.

By changing the vibration amount of different vibrating members 20, the overall vibration amplitude and vibration direction of the connecting plate 30 can be changed. Changing different vibration amplitudes and vibration directions can change the flow speed and flow direction of the glue during the product injection process, so that the direction of glue flow can be specified during glue injection, and the glue injection speed can also be increased.

[0038] In the technical solution of the utility model, a vibration groove 11 is formed on the box body 10, and a fixed end of the vibration member 20 is connected to the vibration groove 11, and a vibration end is connected to a connecting plate 30. The connecting plate 30 is used to place products. The vibration of the vibration member 20 drives the connecting plate 30 to vibrate, and then the vibration is transmitted to the product through the connecting plate 30 to realize the vibration of the product; and a programmable control device is also provided. During the glue filling process, the electronic control device can control the vibration member 20 to vibrate at different frequencies at different positions of the connecting plate 30. By adjusting the vibration frequencies at different positions, the vibration direction of the connecting plate 30 is changed, and then the vibration direction of the product installed on the connecting plate 30 is changed, so that the directional flow of glue on the product during glue filling is realized, the flow speed of the glue is accelerated, the expansion area is increased, and the generation of bubbles during the glue injection process is reduced. When used, the device can realize bubble-free glue filling, with good effect and fast glue filling speed (glue filling and adjustment are synchronized).

[0039] In one embodiment of the present invention, Figure 2 , Figure 3 As shown, the number of the vibration members 20 is at least two, the at least two vibration members 20 are arranged at intervals, the connecting plate 30 is connected to the at least two vibration members, and different vibration members 20 vibrate at different positions of the connecting plate 30 .

[0040] The vibration table 1 also includes at least two vibrators 20 and a connecting plate 30. At least two vibrators 20 are arranged at intervals in the vibration groove 11. The number of vibrators 20 can be 2, 3, 4, 5, etc., which is not limited here. At least two vibrators 20 are arranged at intervals, and then the multiple vibrators 20 can be arranged in a straight line, or in an array, or can be arranged in an irregular shape according to the shape of the connecting plate 30, which is not limited here. Further, when the number of vibrators 20 is 4 or more, the multiple vibrators 20 can be arranged in an array. In this way, the distance between each vibrator 20 and the center of the connecting plate 30 is the same, and then the vibration effect of the vibration frequency of the vibrator 20 in each direction on the corresponding direction of the connecting plate 30 is the same, and the vibration effect of the connecting plate 30 in different directions can be changed accordingly, ensuring that the change amplitude of the vibration effect in each direction remains consistent.

Its working principle is that when an energized coil (conductor) is placed in a magnetic field, a force will be generated, and the magnitude of the force is proportional to the current applied to the coil. In this embodiment, the high acceleration and fast response characteristics of the voice coil motor 20 can be used to change the overall vibration amplitude and vibration direction of the connecting plate 30. Changing different vibration amplitudes and vibration directions can change the flow speed and flow direction of the glue during the product injection process, thereby realizing the specified direction of glue flow during glue pouring.

In this arrangement, since the diagonal line segment is the longest, multiple vibrators 20 are arranged at multiple corners, which can maximize the range of the vibration field generated by the cooperation of multiple vibrators 20, and the distance between each vibrator 20 and the center of the connecting plate 30 is the same, so that the vibration effect of the change of the vibration frequency of the vibrators 20 in each direction for the change of the corresponding direction of the connecting plate 30 is the same, which ensures that the combination of multiple vibrators 20 can be adjusted for different parts in the connecting plate 30, and then the vibration conduction of the connecting plate 30 in different directions can be controlled, and the vibration conduction effect in different directions can be achieved. In addition, through the electrical connection between the four vibrators 20 and the electronic control device, the vibration parameters of different vibrators 20 can be adjusted in real time during the vibration process, and the vibration parameters include vibration amplitude, vibration frequency, vibration action and action duration, etc. Therefore, the flow direction and flow speed of the colloid in the product can be controlled, and the flow direction and flow speed of the colloid in the product can be controlled.
