Advantages are: flexible to scraping and clamping operations, quick and convenient positioning, stability and durability for long time of use.

Description

technical field [0001] The invention relates to an integrated circuit and a display panel, in particular to a device and method for scraping the integrated circuit from the display panel or pressing the integrated circuit on the display panel. Background technique [0002] When manufacturing a display, taking a mobile phone as an example, an integrated circuit is electrically connected to a display panel, so that the operation of the display panel can be controlled by the integrated circuit, and a display can have basic functions. However, in actual situations, failures of the display panel or the integrated circuit often occur, so when a failure occurs, the integrated circuit and the display panel must be separated for further testing. [0003] Therefore, in order to separate the integrated circuit and the display panel, it is best to use a special device to separate the two, so as to avoid errors caused by manual work. [0004] see figure 1 , is a schematic diagram of a ...

Problems solved by technology

[0006] However, this traditional scraping device still has some disadvantages. At first, because the position of the upper hook head 4 needs to be changed by moving horizontally and vertically, that is, the same component bears the positioning of two positions, so the upper hook head 4 The position of the upper hook head 4 will be affected by the progressive error caused by both the components responsible for the lateral movement and the components responsible for the vertical movement. Precision is prone to misalignment

[0007] Furthermore, this type of traditional scraping device is not equipped with any components with fine-tuning functions. Taking lateral movement as an example, it only directly adjusts the lateral position of the upper hook head 4 through the rail 32, and the rail 32 will bear the lateral load at the same time. The scraping action and positioning are difficult in mechanical practice, because the mechanism responsible for the scraping action usually only needs to be strong, and does not require precise positioning control. Therefore, when using this known scraping device, the operator will Often because the position of the cantilever 40 on the track 32 needs to be manually adjusted, the accident that the hand is pinched by the cantilever 40 and the rear stop positioner 20

Or the display panel 6 or the integrated circuit 7 is damaged by an improper collision of the upper hook head 4 because the moving distance of the cantilever 40 cannot be precisely controlled during the fine-tuning process of the cantilever 40 back and forth.

[0008] Conversely, if a component with precise positioning control is used for positioning and scraping at the same time, since the cantilever 40 moves along the direction X' during the scraping operation, the track 32 will be subjected to stress in the direction X, and then produce different degrees of strain , If things go on like this, the internal parts of the component with precise positioning control, such as gears, screws, etc., will increase the clearance, which will affect the precision of positioning control. Therefore, this method will cost a lot of money and is not very practical.

[0009] In addition, the known scraping device does not have a modular design, especially in terms of the backstop locator and the suction table. If the type of the integrated circuit or the display panel changes, the backstop locator or the suction table Changes must be made accordingly, but because there is no modular design, the work of replacing the rear stop positioner and suction table becomes cumbersome and time-consuming.

[0010] As far as the suction table is concerned, because the number and distribution of the vacuum suction holes on the known suction table are too narrow, once the size of the display panel changes greatly, the original suction table must be removed. It's also time consuming

[0011] As far as the upper hook is concerned, the known upper hook does not have the function of pressure control, so it often causes secondary damage to the product during the pressing or scraping operation without knowing it

It is also difficult to adjust the parallelism of the upper hook. The reason is that the cantilever is set on the track. The track will make it difficult to adjust the parallelism. Even if it is adjusted, it is difficult to maintain

In addition, the parallelism of the upper hook head of the known device cannot be adjusted, and as a result, it is very likely that the crimping and preheating cannot be ensured, resulting in damage to the display panel during scraping or residual integrated circuits on the display panel.
