Description

Technical Field

[0001] The present invention relates to the technical field of chip mounters, in particular to a feeder and a chip mounter. Background Art

[0002] Feeder, the transliteration of its Chinese name is Feida, which means feeder or feeder in Chinese. It is a common auxiliary equipment in the production process of integrated circuits. Its main function is to feed the placement head of the placement machine in a regular order. The nozzle of the placement head accurately absorbs the chip provided by the feeder and then transfers it to a specific object. Since the chips need to be packaged and transported during the production process and after production, they generally need to be sealed and rolled with a film and a substrate to facilitate the transportation of the chips under protection. When it is necessary to take out the chip, the feeder needs to be used to remove the film and take out the chip between the film and the substrate.

[0003] The width of the feeder tape is usually between 8mm and 56mm. The specific width depends on the model and the manufacturer's design. Common width specifications include 8mm, 12mm, 16mm, 24mm, 32mm, 44mm and 52mm. The wider the tape, the easier it is to be pulled and deformed, and the imbalance is more likely to occur, which makes it easy for the tape to deviate on the feeder. Once the tape deviates during high-speed operation, the chip will deviate from the predetermined docking position, making it difficult to accurately mount it on a specific object.

[0037] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Preferred embodiments of the present invention are provided in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0038] refer to Figure 1 to Figure 3 The embodiment of the first aspect of the present invention provides a flyer, which at least includes a frame 100, a film cutting member 200, a film material recovery assembly 300 and a base tape traction assembly 400. The film cutting member 200, the film material recovery assembly 300 and the base tape traction assembly 400 are all arranged on the frame 100, and the flyer tape is separated into a long strip of film material and a base tape by the film cutting member 200, wherein the base tape also carries a patch component, such as a chip. The film material is usually a thin film, and a series of traction holes are arranged on both sides of the base tape.

[0039] Specifically, the frame 100 is formed with a feeding channel 110 and a film material recovery bin 120. The feeding channel 110 is usually smooth to avoid abrasion of the continuously passing feeder belt, wherein the top edge of the feeding channel 110 is designed to be rounded, preferably forming a circular arc feed port with a suitable transition arc.

[0040] The film cutting unit 200 is arranged at the top of the frame 100. The material tape enters the film cutting unit 200 from the feeding channel 110 and is separated into the film material and the base tape with the chip. After the film cutting unit 200, the film material and the base tape with the chip move in two opposite directions respectively. The film material enters the film material recovery component 300, and the base tape enters the base tape pulling component 400. The exposed chip is picked up, transferred and assembled by other equipment.

[0041] The film material recovery assembly 300 is disposed on the top of the frame 100 and close to the film material recovery bin 120. Figure 1 , including a tensioning mechanism 310 and a pressing wheel mechanism 320 , the film material passes through the tensioning mechanism 310 and the pressing wheel mechanism 320 in sequence and enters the film material recovery bin 120 .

[0042] Specifically, in an implementation of an embodiment of the present invention, the tensioning mechanism 310 includes a first tensioning wheel group 311, a second tensioning wheel group 312, a guard plate group 313 and a pair of support arms 314. The first tensioning wheel group 311 and the second tensioning wheel group 312 are both connected to the guard plate group 313 to be parallel, and the support arm 314 is connected to the first tensioning wheel group 311 through a retractable pivot. The first tensioning wheel group 311 is closer to the film cutting member 200, and the film material first presses against the upper wheel group surface of the first tensioning wheel group 311, enters between the guard plate group 313, and then presses against the lower wheel group surface of the second tensioning wheel group 312, and then enters the pressing wheel mechanism 320, completing the tensioning connection with the tensioning mechanism 310, ensuring that the film material enters the pressing wheel mechanism 320 in a relatively stable posture. The tensioning limit of the first tensioning wheel and the second tensioning wheel can ensure that the film material receives a relatively uniform tensioning force in the width direction when passing through these two parts. The guard plate group 313 further applies equal and opposite pressures from both sides of the width direction of the film material to ensure that the film material runs between the guard plate group 313.

[0043] The base belt traction assembly 400 is arranged at the top of the frame 100 and away from the film material recovery bin 120, and includes a coaxially connected double-sided gear plate 410. The edges of both sides of the base belt are provided with traction holes that mesh with the double-sided gear plate 410. The base belt is meshed with the double-sided gear plate 410. As the double-sided gear plate 410 rotates, the base belt is continuously collected into the base belt traction assembly 400 and transported to other equipment.

[0044] The feeder provided by the present invention is provided with a coaxially connected double-sided gear plate 410 that can run synchronously. The double-sided gear plate 410 is meshed and connected with the traction holes on the edges of both sides of the base belt, which effectively limits the stability of the posture of the base belt during operation, effectively prevents the base belt with patch components from moving out of position during long-term movement, and can also cope with the long-term stable operation of feeder material strips with larger widths on the feeder.

[0045] Specifically, in another embodiment of the first aspect, Figure 1 to Figure 4As shown, the pressing wheel mechanism 320 in the flyer provided by the present invention comprises an upper pressing plate 321, a lower pressing plate 322, a lower pressing wheel 324 and an upper pressing wheel 323 elastically engaged with the lower pressing wheel 324, and the lower pressing wheel 324 is embedded in the top of the frame 100; the upper pressing plate 321 is arranged at the top of the frame 100, the upper pressing wheel 323 is connected to one end of the upper pressing plate 321 and is linked with the lower pressing wheel 324, and the film material is passed between the upper pressing wheel 323 and the lower pressing wheel 324 to pull the film material to the film material recovery bin 120, and the lower pressing plate 322 transitions from the edge of the lower pressing wheel 324 to the entrance end of the film material recovery bin 120. The upper pressing wheel 323 is elastically engaged with the lower pressing wheel 324, so that the film material is tightly clamped between the upper pressing wheel 323 and the lower pressing wheel 324, and with the rotation of the upper pressing wheel 323 and the lower pressing wheel 324, the film material is continuously pulled to move and enter the film material recovery bin 120. The upper pressing plate 321 and the lower pressing plate 322 can provide a certain barrier for the film material, and the film material passes from above the lower pressing plate 322 into the film material recovery bin 120, thereby preventing the film material from being drawn into the machine outside the material channel.

[0046] Optionally, in combination with the foregoing embodiment, in an implementation of the first aspect, reference is made to Figure 1 to Figure 4 , the pressure wheel mechanism 320 also includes an elastic connecting member 325; the upper pressure wheel 323 is pivotally connected to one end of the upper pressure plate 321, and the elastic connecting member 325 is arranged at the end of the upper pressure plate 321 away from the upper pressure wheel 323; the upper pressure plate 321 is hinged to the frame 100. Through the elastic connecting member 325, the upper pressure plate 321 and the upper pressure wheel 323 on the upper pressure plate 321 form a lever structure on the frame 100, and the upper pressure plate 321 is hinged to the frame 100 at a certain position in the middle, and the upper pressure plate 321 can rotate around the hinge within a certain range. Under the elastic force of the elastic connecting member 325, the upper pressure wheel 323 elastically and continuously presses against the lower pressure wheel 324. More specifically, in combination with the aforementioned implementation, in another specific implementation, such as Figure 4 As shown, the upper pressing plate 321 is provided with a flexible conical guide post 326 facing the frame 100, the frame 100 is provided with a docking groove 130 matching the flexible conical guide post 326, and the elastic connector 325 is sleeved on the flexible conical guide post 326. By providing the flexible conical guide post 326, it is ensured that the elastic connector 325 remains in a fixed position or within a moving range when deforming or maintaining an elastic state, so as to avoid being disengaged from the pressing wheel mechanism 320.

[0047] Optionally, in an embodiment of the first aspect, Figure 1 and Figure 4As shown, the upper pressing wheel 323 and the lower pressing wheel 324 both include a plurality of coaxially connected gear pieces; the upper pressing plate 321 and the frame are both provided with a comb tooth structure 327, and the comb tooth structure 327 corresponding to the upper pressing plate 321 extends from the upper pressing plate 321 into the gear pieces of the upper pressing wheel 323 and matches the protruding contour of the gear piece; the comb tooth structure 327 on the frame extends into the gear pieces of the lower pressing wheel 324 and matches the protruding contour of the gear piece. The upper pressing wheel 323 and the lower pressing wheel 324 composed of gear pieces enable the upper pressing wheel 323 and the lower pressing wheel 324 to mesh with each other, so that the upper pressing wheel 323 and the lower pressing wheel 324 have a greater bite force on the film material, ensuring the dragging and pushing of the film material, so that the film material is stuffed into the film material recovery bin 120. The gear piece can be an integral structure, or it can be composed of multiple smaller pieces of small gear pieces. There may be a certain gap between the gear pieces, so that the entire upper pressing wheel 323 or the lower pressing wheel 324 has a wider operating range, and at the same time the amount of gear pieces used can be reduced.

[0048] The comb-tooth structure 327 on the upper pressing plate 321 and the frame 100 is equivalent to the respective edges of the upper pressing wheel 323 and the lower pressing wheel 324. The comb-tooth structure 327 on the frame 100 is specifically a comb-tooth structure 327 arranged on the lower pressing plate 322 of the frame 100, which gradually extends from the lower pressing plate 322 to between the teeth of the lower pressing wheel 324. The comb-tooth structure 327 is equivalent to setting up a gradually raised step, so that the film material passes through the step and enters the film material recovery bin 120 in a tilted posture, so as to prevent the film material from being clamped in the gap between the upper pressing wheel 323 and the frame 100, or between the lower pressing wheel 324 and the frame 100.

[0049] Optionally, in another embodiment of the first aspect of the present invention, Figure 1 to Figure 3 As shown, the film cutting member 200 includes a rotating cover plate 210 and a clamping plate 220, and the clamping plate 220 and the rotating cover plate 210 are respectively rotatably connected to the frame 100, and the rotating cover plate 210 is provided with two through slots 211 arranged at intervals, and the two gear plates of the double-sided gear plate 410 are respectively passed through the two through slots 211, and the rotating cover plate 210 is provided with a clamping slot 212 at one end away from its rotation axis, and the buckle portion 221 of the clamping plate 220 is connected to the clamping slot 212; the rotating cover plate 210 is provided with a first stripping edge 213 and a second stripping edge 214 between the tensioning mechanism 310 and the double-sided gear plate 410, and the first stripping edge 213 is closer to the tensioning mechanism 310 than the second stripping edge 214.

[0050] The rotating cover plate 210 that can be rotated to open or close is provided with two peeling blades, the first peeling blade 213 is close to the tensioning mechanism 310, and the second peeling blade 214 is close to the base belt traction assembly 400. The two peeling blades can be selected according to the adhesion between the film material (i.e., film) on the feeder belt and the base belt. When the adhesion between the two on the feeder belt is large, the film is peeled off in advance from the second peeling blade 214 to prevent the base belt from being deformed too much and affecting the traction transmission of the double-sided gear plate 410. When the adhesion is small, the film can be peeled off from the first peeling blade 213.

[0051] In addition, the rotating cover plate 210 and the clamping plate 220 cooperate with each other. When the rotating cover plate 210 is placed on the top of the frame 100 and covers the double-sided gear plate 410, the bottom end of the clamping plate 220 is placed in a dedicated clamping slot of the frame 100, and the buckle portion 221 at the top of the clamping plate 220 is clamped into the clamping slot 212 to fix the rotating cover plate 210. When it is necessary to open the rotating cover plate 210, the clamping plate 220 is lifted upward, the buckle portion 221 is disengaged from the clamping slot 212, and the free end of the rotating cover plate 210 can be rotated away from the top of the frame 100, thereby exposing the double-sided gear plate 410 below the rotating cover plate 210.

[0052] Optionally, in another embodiment of the first aspect of the present invention, Figure 1 As shown, the flyer includes a door plate 500, which is hinged to the frame 100, and the door plate 500 is tilted against the frame 100 relative to the direction of gravity to cover the film recovery bin 120. The bottom edge of the door plate 500 is hinged to the frame 100, and is tilted against the film recovery bin 120. Due to its own gravity, the entire door plate 500 covers the outlet of the film recovery bin 120 until the door plate 500 is subjected to a thrust greater than the pressure on the frame 100, and then it will be opened. Specifically, the door plate 500 is rotatably connected to the frame 100 of the flyer, and the door plate 500 forms a small angle with the direction of gravity, so that under normal conditions, the door plate 500 can rely on gravity to press against the frame 100 to cover the outlet of the film recovery bin 120. When the film material in the film material recovery bin 120 accumulates and accumulates to a certain extent, the bin door plate 500 will be squeezed, and the free end of the bin door plate 500 will be pushed away from the frame 100, and the operator can pull out the film material. Furthermore, a cutting edge can be provided on the bin door plate 500 or the frame 100 at the exit of the film material recovery bin 120, and the operator can cut the film material at the cutting edge and take away the film material or film.

[0053] Optionally, in one embodiment of the first aspect of the present invention, reference Figure 1 ,as well as Figure 5 to Figure 7The baseband traction assembly 400 also includes a transmission drive mechanism 420. The double-sided gear plate 410 includes a synchronization shaft 411, a fixed plate 412 with a flat hole 412a at the center, a driving wheel 413, a left gear plate 414a, a right gear plate 414b, a left pin 415a, a left fastener 416a, a right pin 415b and a right fastener 416b. The opposite ends of the synchronization shaft 411 are correspondingly inserted into the flat holes 412a of the two fixed plates 412; the driving wheel 413 is arranged on the right gear plate 414b. The side away from the left gear is in transmission connection with the transmission driving mechanism 420, the left pin 415a is penetrated by the left gear plate 414a and the fixed plate 412 corresponding to the left gear plate 414a, and the left fastener 416a fixes the left gear plate 414a to the corresponding fixed plate 412; the right pin 415b is penetrated by the driving plate, the right gear plate 414b and the fixed plate 412 corresponding to the right gear plate 414b, and the right fastener 416b fixes the driving plate and the right gear plate 414b to the corresponding fixed plate 412.

[0054] Both ends of the synchronization shaft 411 of the double-sided gear plate 410 are flat, and cooperate with the flat hole 412a of the fixed plate 412. Combined with fasteners such as the left pin 415a, the left fastener 416a, the right pin 415b and the right fastener 416b, a driving plate, a right gear plate 414b and a right plate structure corresponding to the fixed plate 412 corresponding to the right gear plate 414b, as well as a left plate structure of the left gear plate 414a and the fixed plate 412 are formed at both ends of the synchronization shaft 411, respectively, to achieve stable and synchronous rotation of the double-sided gear plate 410.

[0055] Optionally, in one embodiment of the first aspect of the present invention, Figure 1 and Figure 8As shown, the frame 100 further includes a handle 140, a transmission rope 150 and an elastic docking portion 160, the handle 140 is arranged at the top of the frame 100, the elastic docking portion 160 is arranged at the bottom of the frame 100, the transmission rope 150 connects the handle 140 and the elastic docking portion 160, and the frame 100 is provided with a plurality of support structures 170 for supporting the transmission rope 150, and the handle 140 is used to pull the elastic docking portion 160 through the transmission rope 150 to release the engagement between the elastic docking portion 160 and the material cart. In combination with the spatial structure on the frame 100, the support structure 170 is arranged at an appropriate position, so that the transmission rope 150 extends from the handle 140 on the top of the frame 100 to the elastic docking portion 160 at the bottom of the frame 100, so that the handle 140 at the top of the frame 100 can conveniently control the operation of the elastic docking portion 160. When the trolley is engaged with the elastic docking part 160, the trolley is docked with the feeder, and the feeder belt in the trolley is used up and the trolley needs to be replaced, the handle 140 is pressed or pulled to pull up the elastic docking part 160 through the transmission rope 150, so that the trolley is detached from the elastic docking part 160. Compared with the previous feeder, the setting of the transmission rope 150 facilitates the loading and unloading of the trolley on the feeder, and the support structure 170 set on the frame 100 adds more force points to ensure the stability of the movement of the transmission rope 150.
