Description

Technical Field

[0001] This invention relates to a carrier tape rotary feeding device, belonging to the field of semiconductor module packaging technology. Background Technology

[0002] Carrier tape is a strip-shaped product used in electronic packaging. It has evenly spaced holes along its length for holding electronic components and positioning holes for indexing and positioning. Existing modular carrier tape consists of a carrier tape layer and a spacer tape layer wound around a tray; the spacer tape serves as a protective layer for the carrier tape.

[0003] Currently, the loading and unloading of module carrier tapes are all done manually, and the specific operations are as follows:

[0004] 1. Employees transport the new module carrier tape tray and the empty isolation tape tray to the loading rack of the equipment. When there is not much material left on the old tray, rotate the old tray and tear the carrier tape off the isolation tape at the end of the module carrier tape and stick it to the loading machine.

[0005] 2. Rotate the old material tray again to remove all the remaining insulating strips from the old material tray, and then insert the empty insulating strip tray into the insulating strip tray position.

[0006] 3. Remove the empty old material tray, load the new module carrier tape tray, and peel off the carrier tape adhesive tape on the new module carrier tape tray to separate the carrier tape from the isolation tape;

[0007] 4. Roll the insulating tape on the new module carrier tape tray into the new empty insulating tape tray;

[0008] 5. Take out the tape connector, hold the head of the new carrier belt and the tail of the previous carrier belt, and place them into the toothed holes of the tape connector to position them. The carrier belt enters the feeding buffer zone, the feeding disc motor rotates to feed the material, and at the same time the feeding buffer zone senses the carrier belt and the feeding mechanism continues to pull the material forward.

[0009] The entire operation process has the following shortcomings:

[0010] 1. Under the original production model, manual feeding takes about 1 minute, and the production time for one batch of material is 30 minutes. This requires workers to feed and unload materials back and forth within 30 minutes, resulting in long operation time, low production efficiency, and impact on overall production capacity requirements. In addition, the labor intensity of workers is high.

[0011] 2. Under the original production model, the degree of automation is low and excessive manual intervention will introduce new appearance defects such as scratches and abrasions due to direct contact between hands and products.

[0043] The present invention will be further described below with reference to specific embodiments.

[0044] However, the description of the present invention is merely a structural or even functional description of the embodiments, and the scope of the present invention is not limited by the embodiments described herein.

[0045] For example, multiple embodiments may have various modifications and forms, and it should be understood that the scope of the present invention includes equivalents that can realize the technical concept.

[0046] like Figures 1-7 As shown, this embodiment is achieved through the following technical solution: it includes a material conveyor belt pushing device 1, a material tray, a moving guide rail device 3, and a rotating support device 2; the material tray and the moving guide rail device 3 are mounted on the rotating support device 2, and the material conveyor belt pushing device 1 is located on one side of the rotating support device 2; the material tray includes a module carrier material tray 4 and an insulating material tray 5.

The head end of the insulating material 7 is wrapped with a magnet, which can be attracted to the bushing of the insulating material tray.

[0047] The aforementioned movable guide rail device 3 consists of two sets, located on either side of the rotating support device 2. Each movable guide rail device 3 includes a movable guide rail assembly 31 that can slide and rotate forward and backward, and a material conveyor assembly 32. The movable guide rail assembly 31 can position the module carrier belt 6 left and right. The material conveyor assembly 32 is used for auxiliary conveying of the module carrier belt, and is equipped with a movable upper guide rail 324, which cooperates with the movable guide rail assembly 31 to position the module carrier belt 6 vertically. The rotating support device 2 is equipped with a rotary motor 21, which can drive the entire support to rotate, thereby driving the material tray and the movable guide rail device to rotate.

[0048] In this embodiment, there are two module carrier trays 4 and two isolation trays 5. Each side of the rotating support device 2 is provided with one module carrier tray and one isolation tray, with the module carrier tray located above the isolation tray. The two module carrier trays and the two isolation trays are arranged symmetrically at the center.

[0049] The material conveyor 1 is fixed by a mounting base. The material conveyor 1 also includes an electric drive device 12, which drives the slide cylinder pusher 11 to rise and fall via a synchronous belt 14. The slide cylinder pusher 11 is equipped with a pusher cylinder 111, which can drive the pusher arm 112 to move back and forth. The suction nozzle 13 is installed at the front end of the pusher arm 112. The slide cylinder pusher 11 is also equipped with a guide column 113 to guide the pusher arm 112 and ensure its operating accuracy.

[0050] The movable guide rail assembly 31 is fixed to the rotating bracket device 2 via a support plate 311. The movable guide rail assembly 31 includes a drive device 312, on which a rotary cylinder 313 is mounted. A movable lower guide rail 314 is mounted on the rotary cylinder 313. The drive device 312 can drive the movable guide rail assembly 31 to move back and forth, and the rotary cylinder 313 can drive the movable lower guide rail 314 to rotate. An isolation belt top wheel 315 for pressing the isolation belt is installed at the rear end of the movable lower guide rail 314. Left and right positioning cover plates 316 are installed on both sides of the front end of the movable lower guide rail 314. The left and right positioning cover plates 316 are used for left and right positioning of the module carrier belt. The left and right positioning cover plates 316 on both sides are elastically connected to the movable lower guide rail 314. A left and right positioning cylinder 317 is also installed at the bottom of the movable lower guide rail 314. The left and right positioning cylinder 317 can control the left and right positioning cover plates 316 on both sides to open or close.

[0051] The material conveyor assembly 32 is connected to the rotating support device 2 via a mounting side plate 321. A material conveyor slide plate 322 is slidably mounted on the mounting side plate 321. A material conveyor device 323 is mounted on the material conveyor slide plate 322. The material conveyor device 323 includes a conveyor roller 3231 and a conveyor motor 3232, with the conveyor roller and conveyor motor being drivenly connected. The material conveyor slide plate 322 is also equipped with a movable upper guide rail 324 and a material conveyor isolation baffle 325. The material conveyor isolation baffle 325 is used to block the module carrier belt, preventing it from sagging as the material tray rotates, thus ensuring that the module carrier belt is guided between the movable lower guide rail 314 and the movable upper guide rail 324.

[0052] The rotating support device 2 further includes a rotating support 22, which is a frame structure and is fixed to a rotating motor 21. An air expansion shaft 23 is installed on the rotating support 22, which can be supplied with compressed air to tighten the material tray. The air expansion shaft 23 is connected to the material tray drive device 24 and is driven to rotate by the material tray drive device 24.

[0053] The working principle of this invention is as follows:

[0054] 1. The module carrier tape drive device rotates to feed the material, causing the insulating tape 7 to hang vertically down;

[0055] 2. The isolation belt detection sensor senses and triggers the material belt pushing device 1. The pushing cylinder 111 extends and the pushing suction nozzle 13 presses and sucks the isolation belt 7 tightly at the top wheel 315 of the isolation belt.

[0056] 3. The material belt pushing device moves down to the center of the insulating belt tray 5, and the pushing cylinder 111 extends forward again to press the insulating belt 7 onto the inner shaft sleeve of the insulating belt tray 5. Because the insulating belt head is wrapped with a magnet, the belt head is attracted to the inner shaft sleeve of the tray.

[0057] 4. The isolation tape tray 5 is triggered to rotate by the drive device, and at the same time the push cylinder 111 retracts, and the isolation tape is wound up and tightened.

[0058] 5. After the insulating tape is wound around several times, the module carrier tape 6 is unscrewed, the carrier tape detection sensor is triggered, the rotary cylinder 313 rotates 45 degrees in the forward direction, and the module carrier tape 6 enters between the upper movable guide rail 324 and the lower movable guide rail 314. It is positioned vertically by the lower movable guide rail 314 and the upper movable guide rail 324, and is pressed between the conveyor roller 3231 and the lower movable guide rail 314.

[0059] 6. When the conveyor motor 3232 is triggered to rotate, the module carrier belt 6 continues to be conveyed forward and enters the lower half of the moving guide rail. The left and right positioning cylinders 317 retract, so that the left and right positioning covers 316 are closed, realizing the left and right positioning of the carrier belt in the guide rail.

[0060] 7. When the carrier belt is conveyed to the end of the moving guide rail, the conveyor motor 3232 stops. At this time, the drive device 312 starts and continues to convey the moving guide rail device 3 and the clamped module carrier belt 6 forward for one end distance.

[0061] 8. The rotary motor 21 is activated, rotating the entire rotary support 22 180 degrees. The rotary cylinder 313 rotates 45 degrees in the opposite direction, and the module carrier belt 6 is conveyed into the fixed guide rail of the feeder. The conveying system in the fixed guide rail then transports the module into the equipment for normal production.

[0062] Of course, the above description is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the embodiments of the present invention. The present invention is also not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of the present invention should fall within the patent coverage of the present invention.
