Description

A board tape attachment mechanism and a chip packaging carrier processing equipment

Technical Field

The present invention belongs to the technical field of chip packaging carrier processing, and in particular relates to a chip packaging carrier plate body tape sticking mechanism and a chip packaging carrier processing equipment.

Background technique

In the semiconductor process or packaging process, chips need to be transported through special carriers. Such carriers usually include a plate made of hard material and a tape attached to one side of the plate. The plate is provided with a through hole, and the tape covers the through hole. The chip is placed in the through hole and adhered to the tape for transportation. For example, Chinese patent CN100555591C discloses such a chip packaging carrier structure.

Since the tape needs to be adhered to the entire surface of the board and the board is relatively narrow around, when the existing tape sticking mechanism (such as the tape sticking mechanism disclosed in Chinese patent CN117401499A) is used to stick the tape, the end of the tape is often not firmly adhered, resulting in the subsequent unloading of the tape being skewed, so that the portion of the tape adhered around the board is relatively small. When subjected to external force, the edge of the tape is easily separated from the board, affecting the chip transportation and the production yield of the chip packaging carrier.

Summary of the invention

The purpose of the present invention is to overcome the shortcomings of the prior art and to provide a chip packaging carrier plate body tape sticking mechanism capable of firmly adhering the tape end to the edge of the plate body and a chip packaging carrier processing equipment with high production yield.

In order to achieve the above object, the technical solution adopted by the present invention is that the plate body adhesive tape sticking mechanism comprises:

A base, which is movable forward, backward, left, right, and up and down and is disposed above the chip packaging carrier plate;

The adhesive tape unit comprises a supporting vertical plate, a tape material tray, a tape passing roller, a tension roller, a material guide plate, a material pulling component, a cutting component and a glue pressing roller, the supporting vertical plate extends vertically in the left and right directions, the upper end of the supporting vertical plate is connected to the base, the tape material tray, the tape passing roller and the tension roller are rotatably connected to the front surface of the supporting vertical plate, the material guide plate is perpendicular to the supporting vertical plate, the upper end of the material guide plate is connected to the supporting vertical plate, the lower end of the material guide plate extends obliquely to the left and lower sides, the lower surface of the material guide plate is provided with a plurality of adsorption holes, the adhesive tape released from the tape material tray passes around the tape passing roller and the tension roller and is adsorbed on the lower surface of the material guide plate by the adsorption holes, the material pulling component is used to pull the adhesive tape to the left and lower sides along the lower surface of the material guide plate, and the cutting component is used to cut the adhesive tape adsorbed on the lower surface of the material guide plate;

The rubber pressing roller is rotatably connected to the lower end of the material guide plate and is suspended at the lower left side of the material guide plate. The outer circumferential surface of the rubber pressing roller is tangent to the lower surface of the material guide plate. The adhesive tape pulled by the material pulling assembly passes over the rubber pressing roller and then extends to the lower left side, so that the end of the adhesive tape is located on the left side of the rubber pressing roller. The upper end of the supporting vertical plate is connected to the base in an upward and downward sliding manner, and the upper end of the material guide plate is rotatably connected to the supporting vertical plate.

When the base moves downward and the supporting vertical plate moves upward to the limit position relative to the base, the glue pressing roller will bypass its own tape and stick it to the plate body. When the cylinder rod of the reverse pulling cylinder retracts, the lower end of the guide plate rotates upward along the clockwise direction. Under the action of gravity, the supporting vertical plate moves downward relative to the base, causing the glue pressing roller to roll horizontally to the left, pressing the end of the tape against the edge of the plate body to achieve a first rolling press. When the cylinder rod of the reverse pulling cylinder extends, the lower end of the guide plate rotates downward in the counterclockwise direction, and the glue pressing roller rolls to the right, pressing the end of the tape against the edge of the plate body again to achieve a second rolling press and lift the supporting vertical plate upward to the limit position relative to the base. After the second rolling press is completed, the base moves to the right, and the glue pressing roller cooperates with the cutting assembly to press the other end of the tape against the plate body to complete the tape sticking operation.

The material pulling plate is provided with a glue pressing boss on the side facing the material guide plate, and the glue pressing boss is located below the rotation axis of the material pulling plate. The material pulling plate has a first working position and a second working position. When the material pulling plate is in the first working position, the material pulling plate rotates in a direction close to the material guide plate so that the glue pressing boss presses the tape adsorbed on the lower surface of the material guide plate. When the material pulling plate is in the second working position, the material pulling plate rotates in a direction away from the material guide plate so that the glue pressing boss is separated from the tape adsorbed on the lower surface of the material guide plate.

Further preferably, the pulling plate has a base plate extending in a direction parallel to the lower surface of the guide plate and an extension portion vertically connected to the base plate and extending to the lower right; the upper end portion of the base plate is rotatably connected to the side wall of the pulling seat; the lower end of the extension portion is rotatably connected to the cylinder rod of the rotating cylinder; and the cylinder body of the rotating cylinder is rotatably connected to the pulling seat.

Detailed ways

The left-right, up-down, and front-back directions described in the present invention are the left-right, up-down, and outside-inside directions in FIG. 1 .

As shown in FIGS. 1 to 12 , the chip packaging carrier processing equipment provided by the present invention includes: a plate conveyor line 10, a glue sticking table 20, a clamping and conveying assembly 30, a plate body tape sticking mechanism 40, and a product conveyor line 50, wherein the plate conveyor line 10 is used to horizontally convey the plate body 1 of the chip packaging carrier from left to right, and the plate conveyor line 10 includes two parallel first belt lines 11, a lifting assembly 12 arranged between the two first belt lines 11, and a sensor for detecting the position and front and back sides of the plate body 1. The jacking assembly 12 includes a jacking seat 121, a jacking plate 122 movably arranged on the jacking seat 121, and a jacking cylinder 123 for driving the jacking plate 122 to move up and down. The front and rear sides of the upper surface of the jacking plate 122 are provided with a jacking positioning column 124, and the jacking positioning column 124 is in a conical shape with a small upper part and a large lower part. The size of the jacking positioning column 124 matches the size of the positioning hole 2 on the plate body 1. The sensor 13 is connected to the support body of the first belt line 11 and is located in the jacking assembly. On the right side of the plate conveyor line 10, when the sensor 13 detects that the plate body 1 moves to the set position, the lifting cylinder 123 is actuated, and the plate body 1 mounted on the two first belt lines 11 is lifted upward by the lifting plate 122 to facilitate the clamping operation of the clamping and conveying assembly 30; the glue sticking table 20 is arranged on the right side of the plate conveyor line 10, and the glue sticking table 20 includes a base 21, a bearing plate 22, a positioning block 23, and a tightening block 24. The base 21 is located on the right side of the plate conveyor line 10, and the bearing plate 22 extends horizontally in the left and right directions. The right end of the carrying plate 22 is rotatably connected to the base 21. The carrying plate 22 is used to place the plate body 1. The carrying plate 22 is provided with a plurality of negative pressure holes (not shown in the figure) for adsorbing the plate body 1. The positioning block 23 is arranged on the upper surface of the carrying plate 22 and is close to the right end of the carrying plate 22. When the plate body 1 is placed on the carrying plate 22, the positioning block 23 is used to limit the position of the right edge of the plate body 1. The pressing block 24 is connected to the base 21 and is located on the left side of the carrying plate 22 so as to be movable left and right. The base 2 1 is also connected to a pressing cylinder 25 for driving the pressing block 24 to move left and right. When the pressing block 24 moves to the right to the limit position, the pressing block 24 can press against the left edge of the plate body 1 placed on the carrier plate 22, so that the position of the plate body 1 remains fixed, so as to improve the stability and accuracy of the subsequent adhesive tape sticking operation; the clamping assembly 30 is arranged at the rear side of the plate body conveying line 10, and the clamping assembly 30 is used to clamp the plate body 1 on the plate body conveying line 10 and move it to the adhesive tape sticking table 20. Specifically, the clamping assembly 30 includes a rotating platform 31 that can move up and down and left and right, and a clamping claw 32 connected to the rotating platform 31 that can open and close left and right. The rotating platform 31 is also connected to a double-headed cylinder 33 for driving the clamping claw 32 to open and close left and right. When the rotating platform 31 moves downward to a set position, the double-headed cylinder 33 can be used to enable the clamping claw 32 to clamp the plate body 1 lifted by the lifting plate 122 from the left and right directions, and then determine whether the rotating platform 31 needs to be rotated 180 degrees according to the front and back results detected by the sensor 13. When rotation is required, the rotating table 31 first moves upward to form a rotation space, and then rotates 180 degrees to turn the plate 1 over. That is to say, when the clamping claw 32 clamps the plate 1, the plate 1 can be turned over by moving the rotating table 31 upward and rotating to ensure that the identification parts such as the QR code on the plate 1 are on the adhesive surface or the non-adhesive surface. Under the premise of ensuring that the front and back sides of the plate 1 are correct, the plate 1 can be moved to the carrier plate 22 by moving the rotating table 31 up and down and left and right, and then the clamping claw 3 is released. 2, the placement operation of the plate body 1 can be completed, the up and down and left and right movements of the rotating table 31 can be realized by means of electric cylinders, servo motors + screw pairs, etc., and the rotation of the rotating table 31 can be realized by a rotating cylinder; after the plate body 1 is placed on the supporting plate 22, the pressing cylinder 25 is actuated to move the pressing block 24 to the right, pressing the plate body 1, thereby locking the relative position of the plate body 1 and the supporting plate 22. At this time, the tape 3 can be applied to the plate body 1 through the body tape applying mechanism 40 provided on the upper plate of the glue applying table 20.

In this embodiment, the plate body tape sticking mechanism 40 includes a base 41 and a tape sticking unit 42, wherein the base 41 is arranged above the plate body 1 (placed on the carrier plate 22) of the chip packaging carrier and can move forward and backward, left and right, and up and down, and the forward and backward, left and right, and up and down movements of the base 41 can be achieved by means of an electric cylinder, a servo motor + a screw pair, etc.; the tape sticking unit 42 includes a support vertical plate 421, a tape material tray 422, a tape roller 423, a tension roller 424, a material guide plate 425, a material pulling component 426, and a cutting component 42 7. The adhesive pressing roller 428 and the reverse pulling cylinder 429; Specifically, the support vertical plate 421 extends vertically in the left-right direction, the upper end of the support vertical plate 421 is connected to the base 41, and the upper end of the support vertical plate 421 is connected to the base 41 so as to be slidable up and down; the tape material disc 422, the tape passing roller 423, and the tension roller 424 are rotatably connected to the front surface of the support vertical plate 421, and the rotation axis of the tape material disc 422, the tape passing roller 423, and the tension roller 424 extends horizontally in the front-back direction; further, the tension roller 424 can The tension roller frame 4241 is rotatably arranged on the tension roller frame 4241, and the tension roller frame 4241 is connected to the front surface of the support vertical plate 421 through the tension cylinder 4242. When the tension cylinder 4242 is actuated, it can drive the tension roller frame 4241 to move left and right, thereby driving the tension roller 424 to move left and right to achieve tension adjustment; the guide plate 425 is perpendicular to the support vertical plate 421, and the upper end of the guide plate 425 is rotatably connected to the support vertical plate 421. The rotation axis of the guide plate 425 extends horizontally in the front-to-back direction, and the lower end of the guide plate 425 is connected to the support vertical plate 421. The end portion extends obliquely to the lower left, and the lower surface of the guide plate 425 (the surface facing the lower right) is provided with a plurality of adsorption holes (not shown in the figure). The adhesive tape 3 released from the tape material tray 422 passes over the adhesive tape roller 423 and the tension roller 424 (in no particular order) and is adsorbed on the lower surface of the guide plate 425 by the adsorption holes (the non-adhesive surface of the adhesive tape 3 faces the lower surface of the guide plate 425); the pulling component 426 is used to pull the adhesive tape 3 toward the lower left along the lower surface of the guide plate 425 to discharge the adhesive tape 3; the cutting component 427 is used to cut the adsorption holes. The adhesive tape 3 attached to the lower surface of the guide plate 425 keeps the adhesive tape 3 attached to the plate body 1 at a set length; the adhesive roller 428 is rotatably connected to the lower end of the guide plate 425 and suspended at the lower left of the guide plate 425, and the rotation axis of the adhesive roller 428 extends horizontally in the front-to-back direction, and the outer circumferential surface of the adhesive roller 428 is tangent to the plane where the lower surface of the guide plate 425 is located. The adhesive tape 3 pulled by the pulling component 426 bypasses the adhesive roller 428 and extends to the lower left, so that the end 4 of the adhesive tape 3 is located on the left side of the adhesive roller 428; The cylinder 429 is arranged on the left side of the guide plate 425, the cylinder body 4291 of the reverse pull cylinder 429 is rotatably connected with the support vertical plate 421, the cylinder rod 4292 of the reverse pull cylinder 429 extends obliquely to the lower right, the end of the cylinder rod 4292 is rotatably connected with the upper surface of the guide plate 425, and the rotation axis of the cylinder body 4291 and the cylinder rod 4292 extends horizontally in the front-rear direction; when the base 41 moves downward to make the support vertical plate 421 move upward to the extreme position relative to the base 41, the glue pressing roller 428 will bypass its own glue The tape 3 is attached to the plate body 1; when the cylinder rod 4292 of the reverse pull cylinder 429 is retracted, the lower end of the guide plate 425 can rotate upward in the clockwise direction. At the same time, the support vertical plate 421 moves downward relative to the base 41 under the action of gravity, eliminating the up and down movement component of the glue pressing roller 428 when it moves obliquely, so that the glue pressing roller 428 can achieve horizontal rolling to the left, thereby pressing the end 4 of the tape 3 against the edge of the plate body 1 to achieve one-time rolling (reverse); when the cylinder rod 4292 of the reverse pull cylinder 429 is extended, the guide plate 4 The lower end of 25 can be rotated downward in the counterclockwise direction to lift the supporting vertical plate 421 upward to the limit position relative to the base 41, eliminating the up and down movement component of the glue pressing roller 428 when it moves obliquely, so that the glue pressing roller 428 can achieve horizontal rolling to the right, and press the end 4 of the tape 3 against the edge of the plate body 1 again to achieve secondary rolling (positive); after the secondary rolling is completed, the base 41 moves to the right, and the glue pressing roller 428 can cooperate with the cutting component 427 to press the other end of the tape 3 against the plate body 1 to complete the tape sticking operation.

The advantages of this setting are:

When the tape is applied, the action of the reverse-pull cylinder 429 and the up-and-down movement of the support vertical plate 421 can be coordinated to enable the glue pressing roller 428 to roll the end 4 of the tape 3 twice, one in reverse and one in forward direction, thereby ensuring the firmness of the adhesion between the end 4 of the tape 3 and the edge of the plate 1, avoiding the subsequent skewness of the tape 3 during unloading, and improving the production yield of the chip packaging carrier.

In this embodiment, the product conveyor line 50 is located on the right side of the glue sticking station 20. The product conveyor line 50 includes two parallel second belt lines 51. The rotation angle of the carrier plate 22 is equal to 180 degrees. When the carrier plate 22 rotates to the extreme position, the carrier plate 22 can flip the board body 1 (chip packaging carrier) with the tape 3 placed thereon to the product conveyor line 50, so that the board body 1 with the tape 3 is flipped and mounted on the two second belt lines 51 for convenient transportation, and the adhesive surface of the tape 3 is exposed from the through hole on the board body 1, which is convenient for the subsequent chip pasting operation; it should be noted that when the carrier plate 22 is flipped, the pressing block 24 must move to the left to avoid interference. Therefore, during the flipping process, the negative pressure hole on the carrier plate 22 needs to maintain negative pressure to avoid relative movement between the board body 1 and the carrier plate 22. At the same time, when the board body 1 is placed on the carrier plate 22 and the pressing block 24 is not pressed tightly, it is also necessary to keep the negative pressure hole at negative pressure to adsorb the board body 1 on the surface of the carrier plate 22.

Such an arrangement can also limit the extreme position of the support vertical plate 421 sliding up and down relative to the sliding seat 41 through the abutment between the annular flange 4213 and the vertical rod seat 4211 and the upper and lower end surfaces of the sliding sleeve 411, and the structure is simple and the use effect is good.

Preferably, the end of the cylinder rod 4292 is rotatably connected to the upper surface of the guide plate 425 through an extension rod 4293, the extension rod 4293 is coaxial with the cylinder rod 4292, and the angle between the extension rod 4293 and the guide plate 425 is 50 to 70 degrees, so as to achieve a balance between the stroke and the back-pull distance of the back-pull cylinder 429.

The moving direction of the material pulling seat 4261 is parallel to the lower surface of the material guide plate 425. The material pulling plate 4263 is rotatably connected to the side wall of the material pulling seat 4261 through the rotating cylinder 4264 and is located below the material guide plate 425. The material pulling plate 4263 is provided with a glue pressing boss 4265 on the side facing the material guide plate 425. The glue pressing boss 4265 is located below the rotation axis of the material pulling plate 4263. The material pulling plate 4263 has a first working position and a second working position. When plate 4263 is in the first working position, the pulling plate 4263 rotates in the direction close to the guide plate 425, so that the glue pressing boss 4265 presses the adhesive surface of the tape 3 adsorbed on the lower surface of the guide plate 425. At this time, in conjunction with the action of the moving cylinder 4262, the pulling seat 4261 can be moved to the lower left to pull the tape 3 along the lower surface of the guide plate 5 to the lower left to achieve feeding. When the pulling plate 4263 is in the second working position, the pulling plate 4263 rotates in the direction away from the guide plate 425, so that the glue pressing boss 4265 is separated from the tape 3 adsorbed on the lower surface of the guide plate 425. At this time, in conjunction with the action of the moving cylinder 4262, the pulling seat 4261 can be moved to the upper right to achieve resetting.

In order to optimize the structure and reduce the space occupied under the material guide plate 425, the pulling plate 4263 has a base plate 4266 extending in a direction parallel to the lower surface of the material guide plate 425 and an extension portion 4267 vertically connected to the base plate 4266 and extending to the lower right. The upper end of the base plate 4266 is rotatably connected to the side wall of the pulling seat 4261, and the rotation axis of the base plate 4266 is located above the extension portion 4267. The lower end of the extension portion 4267 is rotatably connected to the cylinder rod of the rotating cylinder 4264. The cylinder body of the rotating cylinder 4264 is rotatably connected to the pulling seat 4261, and the rotation axis of the cylinder body of the rotating cylinder 4264 is located above the pulling plate 4263.

In order to achieve smooth material pulling and avoid wrinkles, in the present embodiment, the glue pressing boss 4265 extends horizontally in the front-to-back direction, and there are two glue pressing bosses 4265 which are arranged at intervals. The glue pressing boss 4265 is an arc-shaped surface facing the surface of the material guide plate 425. When the material pulling plate 4263 is in the first working position, the glue pressing boss 4265 is in contact with the glue surface line of the tape 3 on the material guide plate 425.

Furthermore, the material pulling component 426 also includes a hot air pipe 4268 connected to the side of the material pulling plate 4263 away from the material guide plate 425. The hot air pipe 4268 extends obliquely from the upper right to the lower left. The hot air pipe 4268 is parallel to the base plate 4266. When the material pulling seat 4261 moves to the lower left to the extreme position, the lower end of the hot air pipe 4268 is aligned with the end 4 of the tape 3 bypassing the glue pressing roller 428 and blows hot air to make the end 4 float, thereby avoiding the end 4 from being folded back when the tape is applied, and activating the adhesive surface of the tape 3.

In this embodiment, the cutting assembly 427 includes a cutter 4271 and a cutter cylinder 4272. The cutter 4271 is movably arranged in a cutter groove 4251 opened on the guide plate 425. The cutter cylinder 4272 is connected to the upper surface of the guide plate 425 and is used to drive the cutter 4271 to move along the cutter groove 4251. The cutter cylinder 4272 is a rodless cylinder. A surrounding plate 4273 is provided on the cutter cylinder 4272. The end of the extension rod 4293 connected to the cylinder rod 4292 of the reverse pull cylinder 429 is rotatably connected to the surrounding plate 4273.

In this embodiment, there are two groups of plate conveyor lines 10, glue sticking tables 20, clamping and conveying components 30, and product conveyor lines 50, which are spaced apart in the front-to-back direction. There is only one group of plate tape sticking mechanisms 40, and the tape sticking operation is realized on the two groups of glue sticking tables 20 by moving the base 41 forward and backward.

As shown in Figure 13, in another embodiment, a spring 4214 is also provided on the vertical rod 4212 of the plate body tape sticking mechanism 40, and the spring 4214 is located below the sliding sleeve 411. The two ends of the spring 4214 are respectively pressed against the sliding sleeve 411 and the vertical rod seat 4211. The spring 4213 has a tendency to drive the vertical rod 4212 to slide downward relative to the sliding sleeve 411. The advantage of such a setting is that the rolling pressure of the glue pressing roller 428 can be increased by the spring 4214, and the downward sliding of the supporting vertical plate 421 relative to the base 41 can be ensured.
