[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses the output end of the first linear module of the Z-axis drive assembly to move in the opposite direction of the Z-axis, thereby driving the slide cylinder of the X-axis drive assembly to move in the opposite direction of the Z-axis. The movement of the slide cylinder in the opposite direction of the Z-axis drives the heating assembly and the pressure holding assembly to move in the opposite direction of the Z-axis. The output end of the slide cylinder shortens, driving the heating assembly and the pressure holding assembly to move in the opposite direction of the X-axis. At this time, the output end of the first linear module continues to move in the opposite direction of the Z-axis, driving the heating assembly and the pressure holding assembly to continue to move in the opposite direction of the Z-axis. This achieves the avoidance of the carrier when the heating assembly moves. After the heating assembly contacts the carrier assembly, it continues to move in the opposite direction of the Z-axis, causing the L-shaped bracket to slide in the Z-axis direction at the output end of the slide cylinder. The counterweight on the upper limit rod of the L-shaped bracket applies a constant pressure to the L-shaped bracket. At this time, the heating assembly and the pressure holding assembly move to the preset position of the carrier assembly for heating and pressure holding, which is beneficial for heating the flexible flat cable while achieving constant pressure holding.

Detailed Implementation

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-4A heating and pressure-holding device includes: a driving mechanism 1, a heating mechanism 2, a transplanting mechanism 3, and a carrier assembly 4. The heating mechanism 2 is installed at the output end of the driving mechanism 1, the transplanting mechanism 3 is located below the heating mechanism 2, and the carrier assembly 4 is installed at the output end of the transplanting mechanism 3. The heating mechanism 2 includes: a heating component and a pressure-holding component. The heating component is located above the carrier assembly 4, and the pressure-holding component is installed on the heating component.

[0013] The heating assembly includes an L-shaped bracket 21, a heat sink 22, and a heating head 23. The L-shaped bracket 21 is slidably connected to the output end of the drive mechanism 1. The heat sink 22 is fixedly mounted on the L-shaped bracket 21, and the heating head 23 is fixedly mounted on the heat sink 22.

[0014] The heating head 23 is placed on the carrier assembly 4 to heat the carrier assembly 4. The heat sink 22 is connected to an external air supply device. The external air supply device blows gas onto the heat sink 22 to dissipate heat. The heat sink 22 dissipates heat, reducing the heat transfer between the heating head 23 and the L-shaped bracket 21, and preventing the high temperature of the heating head 23 from affecting the L-shaped bracket 21 and other parts.

[0015] The pressure-holding assembly includes a limiting assembly and a counterweight assembly. The limiting assembly is mounted on the L-shaped bracket 21, and the counterweight assembly is mounted on the limiting assembly.

[0016] The limiting component includes a limiting rod 24, and a plurality of the limiting rods 24 are fixedly installed on the L-shaped bracket 21.

[0017] The counterweight assembly includes a counterweight block 25, and a plurality of the counterweight blocks 25 are slidably connected to the limiting rod 24.

[0018] The drive mechanism 1 includes a Z-axis drive assembly and an X-axis drive assembly. The Z-axis drive assembly is located on the rear side of the L-shaped bracket 21, and the X-axis drive assembly is installed at the output end of the Z-axis drive assembly.

[0019] The Z-axis drive assembly includes a first linear module 11, which is located behind the L-shaped bracket 21. The X-axis drive assembly includes a slide cylinder 12, which is fixedly installed at the output end of the first linear module 11. The L-shaped bracket 21 is slidably connected to the output end of the slide cylinder 12.

[0020] The output end of the first linear module 11 of the Z-axis drive assembly moves in the opposite direction of the Z-axis, causing the slide cylinder 12 of the X-axis drive assembly to move in the opposite direction of the Z-axis. The slide cylinder 12 moves in the opposite direction of the Z-axis, causing the heating assembly and the pressure holding assembly to move in the opposite direction of the Z-axis. The output end of the slide cylinder 12 shortens, causing the heating assembly and the pressure holding assembly to move in the opposite direction of the X-axis. At this time, the output end of the first linear module 11 continues to move in the opposite direction of the Z-axis, causing the heating assembly and the pressure holding assembly to continue to move in the opposite direction of the Z-axis. After the heating assembly contacts the carrier assembly 4, it continues to move in the opposite direction of the Z-axis, causing the L-shaped bracket 21 to slide in the Z-axis direction at the output end of the slide cylinder 12. The counterweight 25 on the upper limit rod 24 of the L-shaped bracket 21 applies a constant pressure to the L-shaped bracket 21. At this time, the heating assembly and the pressure holding assembly move to the preset position of the carrier assembly 4 to perform heating and pressure holding.

[0021] Example 2: In some embodiments, such as Figures 1-4 In a preferred embodiment of the present invention, the transplanting mechanism 3 includes a second linear module 31, which is located below the heating head 23.

[0022] The carrier assembly 4 includes a carrier 41, which is installed at the output end of the second linear module 31 of the transplanting mechanism 3. The carrier 41 is used to place the circuit board and the flexible flat cable.

[0023] The output end of the second linear module 31 of the transplanting mechanism 3 moves in the opposite direction of the X-axis, causing the carrier 41 to move in the opposite direction of the X-axis, and moving the carrier 41 to the heating position directly below the heating head 23.

[0024] A brass limiting cover plate 5 is fixedly installed on the carrier 41. The brass limiting cover plate 5 is used to position the flexible flat cable and assist in heat conduction.

[0025] Circuit boards and flexible cables are placed on the carrier 41 of the carrier component 4. After manually arranging the circuit boards and flexible cables, the flexible cables are pressed down with brass limit cover 5.

[0026] The counterweight 25 on the limiting rod 24 applies constant pressure to the L-shaped bracket 21, so that the heating head 23 receives constant pressure. The heating head 23 is in close contact with the brass limiting cover plate 5 for heating. The heating head 23 applies constant pressure to the brass limiting cover plate 5. The brass limiting cover plate 5 is heated, which activates the adhesive on the soft flat cable underneath, making it stick to the circuit board.

[0027] A clamping and fixing assembly is installed on the output end of the second linear module 31 of the transplanting mechanism 3. The clamping and fixing assembly includes a double piston rod cylinder 6 and a clamping plate 7. The double piston rod cylinder 6 is installed on the output end of the second linear module 31, and the clamping plate 7 is fixedly installed on the output end of the double piston rod cylinder 6. The end of the clamping plate 7 away from the double piston rod cylinder 6 is located in the X-axis direction of the carrier 41.

[0028] The output end of the double piston rod cylinder 6 of the clamping and fixing component shortens, causing the two clamping plates 7 to move closer to each other, clamping the circuit board on the carrier 41.

[0029] The overall steps are: S1: The carrier assembly 4 moves to the heating station under the drive of the transfer mechanism 3; S2: The Z-axis drive assembly drives the L-shaped bracket 21 to move in the Z-axis direction, and the X-axis drive assembly drives the heating mechanism 2 to move in the opposite X-axis direction; S3: Driven by the X-axis drive assembly, the heating head 23 retracts in the X direction, and the Z-axis drive assembly drives the heating mechanism 2 and the pressure holding mechanism to continue moving in the Z-axis direction until the heating head 23 contacts the brass limit cover plate 5. Once heating is complete, return in the opposite direction.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
