[ first embodiment ] A method for manufacturing a semiconductor device

Fig. 2 shows a schematic structural view of a transfer device according to a first embodiment of the present invention; fig. 3 is a schematic view showing an opened state of a fork of the transfer apparatus according to the first embodiment of the present invention; fig. 4 is a schematic view showing a state where the forks of the transfer apparatus according to the first embodiment of the present invention are closed. Referring to fig. 2-4, the present invention provides a conveyor 10, the conveyor 10 includes: the carrier 01 is a rectangular plate-shaped structure having a flat surface, and has a carrying surface, and when a worker or a mechanical transmission device places the display liquid crystal cell 20 to be assembled on the carrying surface in an actual production process, the carrier 01 can move to the edge of the base 30 on which the driving circuit board 40 is placed under the control of the driving device, and the bonding process of the flexible circuit board 50, the driving circuit board 40 and the display liquid crystal cell 20 is completed with the assistance of the pressing device. After the bonding process is completed, the display liquid crystal cell 20 and the driving circuit board 40 need to be transported together to the next process support. Accordingly, the present invention provides a conveyor 10 further comprising two prongs 02 for carrying the drive circuit board 40.

In order to better support the driving circuit board 30, the two forks 02 are preferably disposed on the same side of the platform 01, and the two forks 02 are specifically shown to be disposed on the backside of the bearing surface of the platform 01, but the present invention is not limited to which side of the platform 01 the forks 02 are specifically disposed, and in other embodiments, the forks 02 may be disposed on one side of the platform 01 facing the base 30.

The tooth fork 02 can be connected with the bearing table 01 in a rotating mode, and the rotating connection can be detachable, so that the later maintenance and the smoother operation of production equipment are facilitated. Specifically, the two forks 02 can rotate synchronously by a certain angle along a direction parallel to the bearing surface of the bearing table 01, so as to increase or shorten the distance that the two forks 02 protrude from the same side edge of the bearing table 01.

For convenience of description, for example, it may be specified that before the bonding and pressing process is started, the forks 02 of the conveying device 10 are always in an initial state, at this time, the forks 02 are relatively far away from the base 30, there is no interaction force between the two, the forks 02 are in an idle state, and the distance protruding from the side edge of the carrier table 01 is the longest, for example, the forks 02 are perpendicular to the protruding side edge in the initial state; when the bonding process is planned, as mentioned above, the transfer device 02 needs to be moved to a position close to the substrate 30, which may be referred to as a bonding state, for example, in which the distance of the prongs 02 protruding from the side edge of the carrier 01 is the shortest or relatively short relative to the initial state, and the position of the prongs 02 relative to the base 30 is relatively fixed, so as to complete the stable bonding process; after the bonding process is completed, the conveyor 10 needs to move away from the base 30 to transport the assembled lcd panel to the next station, and at this time, the fork 02 is gradually moved away from the base 30, and the distance from the side edge of the carrier 01 is gradually increased and returns to the initial state. That is, in the whole process flow, the tooth fork 02 actually changes from the initial state to the bonding state and then to the initial state through the rotation movement, and the distance between the tooth fork 02 and the side edge of the bearing table 01 protruding from the tooth fork also undergoes the process from shortening to increasing. For example, fig. 3 and fig. 4 show the position schematic diagrams of the forks 02 of the conveying apparatus 10 in the bonding state and the initial state, respectively, and of course, the present invention specifically defines the initial state, the specific position of the bonding state forks 02 and the angle of rotation from the initial state to the bonding state forks 02, as long as the forks 02 can achieve the effect of stably supporting the driving circuit board 40, which specifically includes: the maximum distance between the two forks 02 is smaller than the length of the driving circuit board 40; in the initial state, the distance of the two forks 02 protruding the same side edge of the carrier table 01 is larger than the width of the driving circuit board 40.

As shown in fig. 2 to 4, the dental fork 02 includes a fork body 201, and a rotating member 202 and a sliding member 203 which are located at both ends of the fork body 201, the fork body 201 is rotatably connected to the platform 01 through the rotating member 202, and the sliding member 203 is capable of freely rotating in a direction parallel to the bearing surface of the platform 01. The sliding member 203 is preferably in a pie shape, and may be a pulley, but may be in other polyhedral shapes or a sphere, as long as the purpose of facilitating the relative sliding of the fork 02 with respect to the base 30 is achieved. The utility model discloses in, sliding part 203 specifically can adopt antistatic material preparation, or the surface coating has antistatic coating to avoid producing static and causing the damage to the electrical components on the drive circuit board 40 for the gliding in-process of base 30 at sliding part 203.

In this embodiment, the sliding component 203 may be specifically connected to the tooth fork body 201 through a connecting component 90, and the connecting component 203 may be protruded on two opposite sides of the sliding component 203 and be located on the same plane as the tooth fork body 201, so as to ensure that the process resistance of the driving circuit board 40 moving to the tooth fork 02 is smaller, the wear is lower, and the efficiency is higher.

Meanwhile, in order to ensure the free switching and precision requirement of the conveyer 10 in the initial state and the bonding state, the present invention provides a conveyer 10 further comprising an elastic member 60 and a fixing column 70. The specific number of the elastic members 60 may be 1 or more, and when the number of the elastic members 60 is one, for example, two ends of the elastic member 60 may be respectively connected to two of the prong bodies 201; when the number of the elastic members 60 is two, for example, one end of each elastic member 60 may be connected to the bearing table 01, and the other end of each elastic member 60 may be connected to the tooth fork body 201, specifically, as shown in fig. 2, a fixing block may be disposed on the back side of the bearing surface of the bearing table 01, and the end of the elastic member 60 may be fixedly connected to the fixing block. In this embodiment, the fixing column 70 may be disposed at the inner sides of the two fork bodies 201, for example, the position of the fork 02 in the initial state and the angle at which the fork 02 can rotate are limited by the fastening action of the fixing column 70 on the fork bodies 201, and the elastic member 60 is matched to achieve the effect of synchronous rotation of the two forks 02, specifically, the angle range at which the two forks 02 rotate is 0 to 90 °.
