Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1

[0031] Refer to Figures 1-5As shown in the figure, a conveying and cleaning device for a lead frame film pasting device of the present utility model includes a first conveying component 16. The first conveying component 16 includes a first synchronous belt and a liftable baffle 165. A baffle 165 is arranged between two oppositely arranged first synchronous belts. The baffle 165 is used to block the lead frame being conveyed forward to avoid stacking. A cleaning mechanism 2. The cleaning mechanism 2 includes a lower rubber-coated roller 22 driven by a fourth motor 21 after speed reduction. An upper rubber-coated roller 23 is movably arranged above the lower rubber-coated roller 22. The upper rubber-coated roller 23 descends under its own gravity and approaches the lower rubber-coated roller 22. Since the lower rubber-coated roller 22 can rotate actively, and the upper rubber-coated roller 23 is assembled through a rotating shaft and bearings and can only rotate passively. A dust-removing tape or dust-free cloth and other cleaning components are sleeved on the two rubber-coated rollers, which can clean the residual particles or dust on the lead frame. The lead frame completes the surface cleaning operation between the upper rubber-coated roller 23 and the lower rubber-coated roller 22 and is conveyed onto the second conveying component 26. The second conveying component 26 includes two second synchronous belts arranged side by side to support the lead frame. A heating block 265 is arranged between the two second synchronous belts. After the cleaning operation is completed and it needs to be conveyed forward continuously, at this time, in order to facilitate the subsequent film pasting process operation, it is necessary to heat the lead frame during the conveying process.

[0032] Embodiment 2

[0033] Referring to Figures 1-5 As shown in the figure, on the basis of the technical solution of Embodiment 1, for the specific structural design of the first conveying component 16, as Figures 2-3 shown, the first synchronous belt is installed on the second support seat 162. The second support seat 162 is a combination of a vertical plate and a right-angle plate. The two first synchronous belts are respectively arranged at the upper inner side of the second support seat 162 to respectively support the two side parts of the lead frame to be conveyed. A liftable baffle 165 is arranged between the two second support seats 162. The baffle 165 is driven by a lifting cylinder 166. A second sensor 164 is suspended above the baffle 165, generally a photoelectric sensor, which is used to detect whether a sheet product passes by. When the second sensor 164 detects that a sheet product passes by before the next cleaning process is completed, it feeds back to the lifting cylinder 166 to raise the baffle 165 to block the sheet product from being conveyed to the next station, and at the same time feeds back to the front-end feeding process to stop the feeding operation to avoid stacking of the lead frames on the first belt.

[0034] Further, a second motor 161 is provided on the second support base 162. After the speed of the second motor 161 is reduced, it drives the first synchronous belt mechanism 163. The first synchronous belt mechanism 163 includes a driving wheel, a driven wheel for installing the first synchronous belt, and a tensioning and adjusting wheel. The two tensioning and adjusting wheels are coaxial and connected to the output shaft of the second motor 161 after its speed is reduced. The second motor 161 reduces its speed through a speed reduction mechanism, and the speed reduction mechanism can be a gear speed reducer, a belt speed reducer, a chain drive speed reducer, etc., which will not be elaborated here. Since two first synchronous belt mechanisms 163 need to be driven to work simultaneously, the output shaft of the speed reducer is connected to an intermediate shaft, and two driving wheels are provided on the intermediate shaft. The driving wheel, the driven wheel, and the tensioning and adjusting wheel are connected by the first synchronous belt to drive the work. The position of the tensioning and adjusting wheel on the second support plate can be finely adjusted to achieve adjustable tension of the first synchronous belt.

[0035] For the specific structural design of the second conveying component 26, as Figure 5 shown, the second synchronous belt is installed on the third support base 262. A heating block 265 is provided between the two third support bases 262. The heating block 265 is arranged along the conveying direction and is provided with a supporting temperature control component, such as a thermocouple or a temperature control probe, etc., which will not be elaborated here. In addition, the height of the heating block 265 is lower than the upper conveyor belt lead frame of the second synchronous belt to avoid affecting the conveying. Third sensors 264 are respectively provided at both ends of the heating block 265 to feedback the temperature or position relationship of the front and rear ends of the lead frame during conveying. In addition, a third motor 261 is provided on the third support base 262. After the speed of the third motor 261 is reduced, it drives the second synchronous belt mechanism 263 to work. The second synchronous belt mechanism 263 has the same structure as the first synchronous belt mechanism 163 and can be designed with reference to the above content, which will not be elaborated here.

[0036] Embodiment 3

[0037] Referring to Figures 1-5 shown, on the basis of the technical solution of Embodiment 1, for a conveying and cleaning device of a lead frame laminating device, for the specific structural design of the cleaning component, as Figure 4 shown, the lower rubber-coated roller 22 is rotatably installed on the fourth support base 25. The shafts at both ends of the lower rubber-coated roller 22 are installed on the fourth support base 25 through bearings. A lifting movable plate 24 is slidably provided on the fourth support base 25. Specifically, a vertical guide rail is fixed inside the fourth support base 25, and a chute matching the vertical guide rail is provided on the lifting movable plate 24, so that the lifting movable plate 24 can slide in the vertical direction. A rotatable upper rubber-coated roller 23 is installed on the lifting movable plate 24. One end of the upper rubber-coated roller 23 is installed on the lifting movable plate 24 through a shaft and a bearing. In this way, the upper rubber-coated roller 23 approaches the lower rubber-coated roller 22 under its own gravity, so that a certain downward pressing force can be applied when the lead frame passes between the two, and the cleaning operation is cleaner.

[0038] Further, the fourth motor 21 is connected to a speed reducer. The speed reducer is fixed on the side of the fourth support base 25 and is connected to the rotating shaft of the lower rubber-coated roller 22 through an output shaft. The lower rubber-coated roller 22 is the driving part, and the upper rubber-coated roller 23 is the driven part. Both the lower rubber-coated roller 22 and the upper rubber-coated roller 23 are sleeved with components for cleaning, such as a dust sticking tape or a dust-free cloth, etc., which can clean the residual particles or dust on the lead frame. The lead frame is conveyed between the upper rubber-coated roller 23 and the lower rubber-coated roller 22 to complete the surface cleaning operation.
