Automatic dispensing machines are specialized equipment that replaces manual dispensing. Their application significantly improves production efficiency and product quality, enabling processes that are impossible to perform manually.

[0003] In automatic dispensing equipment for semiconductor chip strips, the equipment typically includes an unwinding device, a dispensing device, a curing device, and a winding device in sequence along the conveying direction of the semiconductor chip strip. Existing curing devices have only one outlet, with a discharge mechanism at the outlet to pull out and guide the dried semiconductor chip strip from the curing device before the winding device rewinds it. If the curing device is configured to accommodate semiconductor chip strips with different drying times, it can allow the semiconductor chip strip to travel one layer in a straight line or three layers in an S-shape within the curing device, with different semiconductor chip strips selecting the curing path as needed. In this case, the curing device needs to have two outlets, one at the top and one at the bottom. The existing discharge mechanism cannot meet the usage requirements. Therefore, a discharge mechanism adaptable to multiple outlets of different heights is proposed to solve the problems existing in the prior art. Utility Model Content

They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0028] like Figure 1 , Figure 2 As shown, a discharge mechanism adaptable to multiple discharge ports of different heights includes: a discharge assembly 4, a drive assembly for moving the discharge assembly 4 to discharge ports of different heights, and multiple fixing assemblies for fixing the discharge assembly 4 at the discharge ports of different heights. The discharge assembly 4 includes a guide rail module for conveying the material belt and a material belt drive module for driving the material belt forward on the guide rail module. In this embodiment, there are two discharge ports, namely a first discharge port 2 and a second discharge port 3 (e.g., [missing information]) disposed vertically on the housing 1 of the curing device. Figure 1 (as shown); Of course, the unloading mechanism of this utility model that adapts to multiple discharge ports of different heights can adapt to three or more discharge ports, and only requires setting a fixed component and a first sensor 5 with the same number of discharge ports. The unloading mechanism also includes multiple first sensors 5 for position detection of whether the unloading component 4 has moved to the discharge port of different heights. The first sensor 5 is a slot-shaped photoelectric sensor, which is installed on the housing 1 of the curing device, and a sensing plate 6 that can block the light beam of the slot-shaped photoelectric sensor is fixedly installed on the slider 8 below (as shown). Figure 5 (As shown).

[0029] like Figure 2 , Figure 3 As shown, the driving assembly includes a linear guide rail 7 fixedly mounted vertically on the housing 1 of the curing device, and a slider 8 slidably mounted on the linear guide rail 7. The unloading assembly 4 is entirely mounted on the slider 8. Using the linear guide rail 7 and the slider 8 results in a simpler and more practical structure. Of course, in another embodiment, the driving assembly can also be a linear module or a servo cylinder; the unloading assembly 4 is entirely mounted on a mounting plate 9, and the mounting plate 9 is fixed to the slider 8; as shown... Figure 3 As shown, each fixing component includes an L-shaped clamping plate 10 fixedly mounted on the housing 1 of the curing device, and an insert plate module that engages with the clamping plate 10 on the mounting plate 9. The insert plate module includes a U-shaped groove plate 11 fixed to the bottom surface of the mounting plate 9 and an insert plate 12 slidably mounted in the groove of the U-shaped groove plate 11. The end of the insert plate 12 is provided with a slot for engaging with the clamping plate 10. After the insert plate 12 and the clamping plate 10 are engaged, the insert plate 12 is then fixed to the mounting plate 9 with screws, thus fixing the unloading component 4 after lifting and moving. The two ends of the linear guide rail 7 in the length direction are respectively provided with an upper limit stop 13 and a lower limit stop 14 to limit the sliding stroke of the slider 8. The upper limit stop 13 and the lower limit stop 14 form a rigid mechanical limit to prevent the slider 8 from overtraveling and falling off the linear guide rail 7, avoiding accidental collisions or equipment damage, and improving operational safety. The guide rail module includes a pair of straight rails 15 and a pair of curved rails 16 that are spliced ​​together in sequence. Both the pair of straight rails 15 and the pair of curved rails 16 are provided with guide grooves for guiding and supporting the material strip.

[0030] like Figures 4-6As shown, the material belt drive module includes a first figure-eight wheel group and a second figure-eight wheel group for clamping and conveying the material belt to both sides, and a figure-eight wheel drive module for driving the first figure-eight wheel group and the second figure-eight wheel group to rotate. The first figure-eight pulley group includes a first driven figure-eight pulley 17 and a first driving figure-eight pulley 18 arranged vertically. The second figure-eight pulley group includes a second driven figure-eight pulley 19 and a second driving figure-eight pulley 20 arranged vertically. The figure-eight pulley drive module includes a drive component, a first synchronous pulley 21, a second synchronous pulley 22, a third synchronous pulley 23 coaxially connected to the first driving figure-eight pulley 18, a fourth synchronous pulley 24 coaxially connected to the second driving figure-eight pulley 20, a first synchronous belt 25 sleeved on the first synchronous pulley 21 and the third synchronous pulley 23, a second synchronous belt 26 sleeved on the second synchronous pulley 22 and the fourth synchronous pulley 24, a first tensioning pulley 27 for tensioning the first synchronous belt 25, and a second tensioning pulley 28 for tensioning the second synchronous belt 26. The first synchronous pulley 21 and the second synchronous pulley 22 are both mounted on the output shaft of the drive component. In this embodiment, the drive component is a motor 29. The working principle of the conveyor belt drive module is as follows: the output shaft of motor 29 rotates, thereby simultaneously driving the first synchronous pulley 21 and the second synchronous pulley 22 to rotate. The rotation of the first synchronous pulley 21 drives the third synchronous pulley 23 to rotate via the first synchronous belt 25, which in turn drives the first active spool 18, coaxially connected to the third synchronous pulley 23, to rotate. The first active spool 18, together with the first driven spool 17, drives the conveyor belt forward. Similarly, the rotation of the second synchronous pulley 22 drives the fourth synchronous pulley 24 to rotate via the second synchronous belt 26, which in turn drives the second active spool 20, coaxially connected to the fourth synchronous pulley 24, to rotate. The second active spool 20, together with the second driven spool 19, drives the conveyor belt forward. The unloading mechanism also includes a first electrostatic gun 30 for destaticating the upper surface of the conveyor belt and a second electrostatic gun 31 for destaticating the lower surface of the conveyor belt. The first electrostatic gun 30 and the second electrostatic gun 31 eliminate static electricity generated by friction on the conveyor belt and prevent the conveyor belt from adsorbing dust.

[0031] This utility model discloses a discharge mechanism that adapts to multiple discharge ports of different heights. After determining which discharge port of the curing device the material belt will discharge from based on the drying time of the material belt, for example, discharging from the first discharge port 2, the discharge assembly 4 is initially located at the second discharge port 3. First, unscrew the screws of the fixing plate 12, pull the plate 12 outwards to the side away from the clamping plate 10, and then manually push the discharge assembly 4 to the first discharge port 2. Push the plate 12 into the clamping plate 10 so that the clamping plate 10 is inserted into the slot of the plate 12. Then, fix the plate 12 to the mounting plate 9 with screws to complete the movement of the discharge assembly 4.
