Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to an assembly fixture for a display module. Background Technology

[0002] To prevent the display module from detaching from the customer housing during whole-machine vibration testing, a layer of double-sided foam adhesive is usually added to the back of the cover plate during the manufacturing process of the vehicle display screen. To ensure that the back of the cover plate is not scratched or dirty during the factory assembly process, a process film is usually added to the back of the cover plate. When it comes time to apply the double-sided foam adhesive, the process film is first manually removed, and then the double-sided foam adhesive is precisely applied to the back of the cover plate.

[0003] However, when using this method for application, on the one hand, workers may miss peeling off the process film when applying the double-sided adhesive to the foam, resulting in the display module not meeting the requirements after shipment; on the other hand, applying by hand can easily damage the display module.

[0025] The embodiments of this application will now be described in detail with reference to the accompanying drawings. Example 1

[0026] One embodiment of this application provides an assembly fixture for a display module, which will be referred to below. Figure 1 This application provides a detailed description of an assembly fixture for a display module, such as... Figure 1 As shown:

[0027] An assembly fixture for a display module according to Embodiment 1 of this application includes:

[0028] The tooling body 100 has a first groove 101 on its upper surface. A tear detection point 107 is provided on the outer side of the first groove 101 corresponding to the position of the tear handle of the process film of the display module. An infrared detector 108 is provided on the tear detection point 107. An alarm 109 electrically connected to the infrared detector 108 is also provided on the tooling body 100.

[0029] In this embodiment, the alarm 109 is a buzzer.

[0030] In other embodiments, the alarm 109 may also be any one of a buzzer, an LED light, and an audible and visual alarm.

[0031] In this embodiment, the first groove 101 is further provided with a backlight groove 102, and the backlight groove 102 is further provided with a third clearance groove 103 and a fourth clearance groove 104 that penetrate the tooling body 100.

[0032] In this embodiment, the tooling body 100 is also provided with material feeding grooves 105 extending to the first groove 101 on both sides to facilitate the picking and placing of the display module.

[0033] In this embodiment, a cover plate positioning post 106 perpendicular to the bottom of the groove is also provided in the first groove 101.

[0034] In this embodiment, one cover plate positioning post 106 is provided at each end of the first groove 101.

[0035] Understandably, the first groove 101 is used to place the display module, the backlight groove 120 is used to place the backlight module that supports the display module, the third clearance groove 103 and the fourth clearance groove 104 are used to clear the bolts and electronic components on the back of the backlight module to prevent them from being crushed, and the cover plate positioning post 106 is used to limit the movement of the cover plate.

[0036] In this embodiment, the tooling body 100 is provided with fixing grooves 110 extending into the inner side of the tooling body 100 at both ends, so as to fix the tooling body 100 and ensure that the tooling body 100 remains stable during the application process.

[0037] It should be noted that the assembly sequence of the entire display module is: cover plate + OCA + TFT display screen + backlight module + foam double-sided adhesive. During the assembly process, to prevent the ink on the back of the cover plate from being scratched, a protective film is attached to the back of the cover plate. The protective film is peeled off at the part that overlaps with the TFT and backlight, leaving the protective film for the part where the foam double-sided adhesive is attached. The assembly tool in this embodiment is used to attach the foam double-sided adhesive.

[0038] The working process of this application embodiment is as follows: When the operator places the display module assembled in the previous process into the fixture, when the infrared detector 108 detects that there is an obstruction above, it is considered that the protective film has not been removed and will transmit a signal to the alarm. The alarm will sound an alarm to remind the operator to remove the protective film as soon as possible and attach the foam double-sided adhesive to avoid missing the protective film.
