[0001] This utility model relates to the field of tape splicing technology, and in particular to an automatic tape splicing device. Background Technology

[0002] In the testing or processing of semiconductor chips, different tape rolls are usually spliced ​​to ensure a continuous supply of product tape. However, in the current technology, tape splicing mostly relies on manual operation. This method is not only time-consuming and labor-intensive, but also makes it difficult to guarantee the quality of the splicing. Once problems such as weak tape adhesion or inaccurate tape alignment occur, production efficiency will be greatly reduced, and even product quality will be affected.

The tape-transfer section is configured to move the first tape to an adhesive application position aligned with a second tape, so that the first tape and the second tape are respectively adhered to opposite sides of the first tape and the second tape at the adhesive application position, thereby connecting the first tape and the second tape.

[0010] As a further improvement of this utility model, the automatic tape splicing device further includes a first driving component and a second driving component. The first driving component and the second driving component are respectively disposed at one end of the carrier tape guide rail. The first driving component drives the first material tape to move along a first direction extending from the carrier tape guide rail, and the second driving component drives the second material tape to move along the first direction as well.

[0011] As a further improvement of this utility model, the carrier rail includes a first rail assembly and a second rail assembly, wherein the first material strip and the second material strip both span across the first rail assembly and the second rail assembly;

[0012] The automatic tape splicing device also includes a width adjustment component, which is connected to the first guide rail assembly and / or the second guide rail assembly to adjust the width between the first guide rail assembly and the second guide rail assembly to accommodate tapes of different widths.

[0013] As a further improvement of this utility model, the first guide rail assembly and the second guide rail assembly cooperate to form an adhesive dispensing position and an adhesive application position. The carrier guide rail forms an adhesive dispensing groove at the adhesive dispensing position and an adhesive application groove at the adhesive application position. The adhesive dispensing groove and the adhesive application groove are configured to allow the adhesive dispensing part to pass between the first guide rail assembly and the second guide rail assembly.

[0014] As a further improvement of this utility model, the adhesive dispensing part includes a lifting mechanism and a vacuum suction cup. The vacuum suction cup includes a plurality of vacuum suction holes to adsorb the first adhesive tape. The lifting mechanism drives the vacuum suction cup to move along an extension direction perpendicular to the carrier tape guide rail, and the vacuum suction cup adsorbs the back of the first adhesive tape.

[0015] As a further improvement of this utility model, the lifting mechanism is configured at the adhesive application position, and the lifting mechanism drives the vacuum suction cup to move towards the second tape until the first tape and the second tape are both attached to the same connection position of the first material tape and the second material tape.

[0016] As a further improvement of this utility model, the adhesive transfer part includes an adhesive transfer guide rail and an adhesive transfer drive part. The adhesive transfer guide rail is aligned between the first guide rail assembly and the second guide rail assembly. The adhesive transfer guide rail extends along the extension direction of the carrier tape guide rail.

Detailed Implementation

[0035] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0036] It should be understood that terms such as “above,” “over,” “below,” and “under” used herein to indicate spatial relative position are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms “spatial relative position” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0037] One embodiment of this utility model provides an automatic tape splicing device that enables automatic double-sided splicing of a first tape and a second tape, thereby improving production efficiency and ensuring splicing quality.

[0038] An automatic tape-attaching device 100 of this embodiment, such as Figure 1 and2 As shown, it includes a carrier rail 10, a first tape application mechanism 20, a second tape application mechanism 30, and a tape transfer mechanism 40.

[0039] The carrier rail 10 is used to place the first and second tapes. These tapes are typically strip-shaped materials carrying semiconductor chips or other electronic components and need to remain stable and easy to handle during connection. In this embodiment, the carrier rail 10 employs a design of two parallel metal rails, located on either side of the device, forming a stable support platform between them. The rail surfaces are polished to reduce frictional resistance during tape movement. The length and width of the rails are designed according to the tape dimensions to ensure the tape can be placed flat and move along the rail direction.

[0040] The first and second tapes are placed on the carrier guide rail 10, with their connecting ends close to the middle area of ​​the guide rail, in preparation for subsequent adhesive application. The carrier guide rail 10 not only provides support but also guides the movement of the tapes, ensuring that the tapes remain stable during the connection process and preventing offset or skew.

[0041] The first tape-applying mechanism 20 provides a first tape; the second tape-applying mechanism 30 provides a second tape to achieve double-sided bonding of the tape. These two mechanisms are functionally identical but are installed in opposite positions and operating directions to accommodate the need for bonding tape to opposite sides of the tape.

[0042] The tape transfer mechanism 40 includes a tape taking part 41 and a tape transferring part 42. The tape taking part 41 takes a first tape, and the tape transferring part 42 moves the tape taking part 41. The tape transferring part 42 is configured to move the first tape to an adhesive application position 14 aligned with the second tape, so that the first tape and the second tape are respectively adhered to opposite sides of the first tape and the second tape at the adhesive application position 14, thereby connecting the first tape and the second tape.

[0043] The tape transfer mechanism 40 achieves high-precision transfer and alignment of the first tape through the coordinated work of the adhesive taking part 41 and the adhesive transferring part 42. The first tape and the second tape firmly connect the first material tape and the second material tape together to form a continuous material tape structure.

[0044] This embodiment adopts a double-sided adhesive design, with the first and second adhesive tapes respectively bonded to opposite sides of the material strip. Compared with the traditional single-sided adhesive method, the bonding force is stronger, which can effectively prevent the material strip from breaking during subsequent processing or transportation, ensuring the continuity and stability of the production line.

[0045] Furthermore, the automatic tape splicing device 100 also includes a first drive component 50 and a second drive component 60. The first drive component 50 and the second drive component 60 are respectively disposed at one end of the carrier belt guide rail 10. The first drive component 50 drives the first material belt to move along the first direction extending along the carrier belt guide rail 10, and the second drive component 60 drives the second material belt to move along the first direction as well.

[0046] like Figure 1 , 2 As shown in Figures 3, 8, and 9, the synergistic effect of the first driving component 50 and the second driving component 60 enables the first and second material strips to meet and connect at the adhesive application position 14.

[0047] Both the first drive assembly 50 and the second drive assembly 60 include the following structures:

[0048] The motor, as the power source, can be a stepper motor or a servo motor to achieve high-precision position control.

[0049] The transmission mechanism is used to convert the rotary motion of the motor into the linear motion of the material belt. It can take the form of a gear-rack system, belt drive or screw drive.

[0050] Clamping devices are used to secure the end of the material strip and prevent it from slipping during movement. They are typically designed with pneumatic grippers or mechanical clamps.

[0051] To clearly express the position and direction described in this embodiment, the first direction is defined as the direction from right to left. Figure 1 As shown, the second drive component 60 is located to the left of the first drive component 50, and the opposite direction is to the right. Figure 1 The automatic conveyor belt assembly 100 is placed on a horizontal surface, with the direction of gravity defined as downward and the opposite direction defined as upward.

[0052] The first drive assembly 50 and the second drive assembly 60 clamp the ends of the first and second material strips. After the motor starts, the transmission mechanism drives the clamping device to move to the left along the carrier belt guide rail 10, conveying the first and second material strips to the adhesive application position 14.

[0053] The carrier rail 10 includes a first rail assembly 11 and a second rail assembly 12, with the first and second strips both spanning across the first rail assembly 11 and the second rail assembly 12.

[0054] The first guide rail assembly 11 and the second guide rail assembly 12 are arranged in parallel to form a support platform. The first and second material strips span across these two guide rail assemblies, with the edges of the material strips contacting the guide rail assemblies to ensure stability during movement.

[0055] The automatic tape splicing device 100 also includes a width adjustment component 80, which is connected to the first guide rail assembly 11 and / or the second guide rail assembly 12 to adjust the width between the first guide rail assembly 11 and the second guide rail assembly 12 to accommodate tapes of different widths.

[0056] like Figure 8 and 9 As shown, the width adjustment assembly 80 includes a lead screw mechanism and a drive motor. The lead screw mechanism consists of a lead screw and two nuts, which are respectively fixed to the first guide rail assembly 11 and the second guide rail assembly 12. The lead screw passes through the nuts, and the threads of the two nuts are opposite (one is left-handed and the other is right-handed). The drive motor is connected to the lead screw and is responsible for driving the lead screw to rotate.

[0057] When the drive motor starts, it rotates the lead screw. Since the threads of the two nuts are in opposite directions, the rotation of the lead screw causes the nuts to move axially inward or outward simultaneously. This movement of the nuts causes the first guide rail assembly 11 and the second guide rail assembly 12 to move closer or further apart, thereby changing the width of the carrier belt guide rail 10. By controlling the rotation direction and speed of the motor, the guide rail width can be precisely adjusted to accommodate different specifications of conveyor belts.

[0058] The width adjustment component 80 provides the carrier rail 10 with a high degree of flexibility, enabling it to accommodate various tape widths. This design avoids tape offset or drop problems caused by width mismatch, improving the versatility of the equipment and production efficiency.

[0059] The first guide rail assembly 11 and the second guide rail assembly 12 cooperate to form an adhesive dispensing position 13 and an adhesive application position 14. The carrier guide rail 10 forms an adhesive dispensing groove 131 at the adhesive dispensing position 13 and an adhesive application groove 141 at the adhesive application position 14. The adhesive dispensing groove 131 and the adhesive application groove 141 are configured to allow the adhesive dispensing part 41 to pass between the first guide rail assembly 11 and the second guide rail assembly 12.

[0060] The glue-taking position 13 is the position where the glue-taking part 41 obtains the first tape, and the adhesive-applying position 14 is the operation position for connecting the material tape.

[0061] The height of the adhesive dispensing and application can be customized based on different devices. The adhesive dispensing position 13 can be the location of the adhesive dispensing slot 131 or a position directly above the adhesive dispensing slot 131; similarly, the adhesive application position 14 can be the location of the adhesive application slot 141 or a position directly above the adhesive application slot 141.

[0062] For example in Figure 4In this process, after the adhesive dispensing part 41 passes through the adhesive dispensing groove 131 between the first guide rail assembly 11 and the second guide rail assembly 12, it can obtain the first adhesive tape at the adhesive dispensing groove 131, or it can move upward to the position of the first adhesive tape to obtain the first adhesive tape. After the adhesive dispensing part 41 passes through the adhesive applicator groove 141 between the first guide rail assembly 11 and the second guide rail assembly 12, it can apply the first and second adhesive tapes at the adhesive applicator groove 141, or it can move upward to the position of the second adhesive tape to apply the second adhesive tape.

[0063] After the adhesive dispensing unit 41 picks up the adhesive tape at the adhesive dispensing position 13, it moves along the carrier belt guide rail 10 to the adhesive application position 14. At the adhesive application position 14, the adhesive dispensing unit 41 can smoothly pass through the gap in the guide rail and apply the first adhesive tape to the material belt connection end.

[0064] like Figure 3 and 4 As shown, the adhesive dispensing part 41 includes a lifting mechanism 412 and a vacuum suction cup 411. The vacuum suction cup 411 includes a plurality of vacuum suction holes to adsorb the first adhesive tape. The lifting mechanism 412 drives the vacuum suction cup 411 to move along the extension direction perpendicular to the carrier tape guide rail 10, and the vacuum suction cup 411 adsorbs the back of the first adhesive tape.

[0065] The adhesive dispensing unit 41 is mounted on the bracket of the adhesive transfer unit 42. The lifting mechanism 412 is a cylinder, with the cylinder body fixed to the bracket and the piston rod end connected to the vacuum suction cup 411. The vacuum suction cup 411 is rectangular, with multiple vacuum suction holes evenly distributed on the bottom, and is connected to the vacuum pump through a hose.

[0066] When picking up the adhesive, the cylinder piston rod extends, driving the vacuum suction cup 411 to rise to the position of the first adhesive strip. The vacuum pump starts, generating negative pressure through the vacuum suction port to adsorb the back of the first adhesive strip. After adsorption is complete, the piston rod retracts, and the suction cup along with the adhesive strip retracts downwards, ready for transfer.

[0067] The vacuum suction cup 411 firmly holds the adhesive tape, preventing it from slipping or deforming during transfer. The lifting mechanism 412 provides precise vertical movement, ensuring accurate adhesive pickup and application positions 14 and improving bonding consistency.

[0068] Furthermore, the lifting mechanism 412 is configured at the adhesive application position 14, and the lifting mechanism 412 drives the vacuum suction cup 411 to move towards the second adhesive tape until the first adhesive tape and the second adhesive tape are both attached to the same connection position of the first material tape and the second material tape.

[0069] The lifting mechanism 412 is not only used to pick up the adhesive, but also to drive the vacuum suction cup 411 to move towards the second tape at the adhesive application position 14 until the first tape and the second tape are attached to the same connection position of the material tape.

[0070] In this embodiment, the cylinder stroke of the lifting mechanism 412 is sufficient to cover the height change from adhesive dispensing to adhesive application. The first adhesive tape moves from bottom to top, and the second adhesive tape application mechanism 30 places the second adhesive tape above the material belt.

[0071] At the adhesive application position 14, the lifting mechanism 412 drives the vacuum suction cup 411 (to adsorb the first adhesive tape) to move upward until the first adhesive tape adheres to the lower surface of the connecting end of the first and second material tapes, and the second adhesive tape adheres to the upper surface. After adhesion, the vacuum pump is turned off, the suction cup releases the first adhesive tape, and the lifting mechanism 412 retracts.

[0072] The precise control of the tape transfer mechanism 40 enables the synchronous bonding of the first and second tapes, improving the connection strength and alignment accuracy, and avoiding the instability of single-sided bonding.

[0073] Furthermore, the adhesive transfer section 42 includes an adhesive transfer guide rail and an adhesive transfer drive section. The adhesive transfer guide rail is aligned between the first guide rail assembly 11 and the second guide rail assembly 12. The adhesive transfer guide rail extends along the extension direction of the carrier tape guide rail 10. The adhesive transfer drive section moves the adhesive taking section 41 and reciprocates along the adhesive transfer guide rail between the adhesive taking position 13 and the adhesive applying position 14.

[0074] In this embodiment, the adhesive transfer guide is a linear guide, installed below the carrier tape guide 10. A slider is provided on the adhesive transfer guide, and the servo motor of the adhesive transfer drive unit drives the slider to move. The adhesive taking part 41 is fixed to the slider.

[0075] The servo motor receives a control signal and drives the slider to move along the guide rail, moving the glue-taking part 41 from the glue-taking position 13 to the glue-applying position 14, or vice versa. During the movement, the glue-taking part 41 carries the first adhesive tape, ensuring flatness and accurate positioning.

[0076] like Figure 5 , 6 As shown in Figures 7 and 8, both the first tape-applying mechanism 20 and the second tape-applying mechanism 30 include a tape roll 21, a cutter assembly 22, and a tape clamping assembly 23.

[0077] Tape roll 21 is used to supply tape, and the tape roll 21 of the first tape applicator 20 and the second tape applicator 30 rotate in opposite directions during the tape feeding process.

[0078] In this embodiment, the tape roll 21 is mounted on a rotating shaft and driven by a stepper motor. The tape clamping assembly 23 consists of a pneumatic gripper and a slide rail, with the pneumatic gripper able to move along the slide rail. The cutting assembly 22 consists of a cylinder-driven blade used for cutting the tape.

[0079] The adhesive clamping assembly 23 is configured to clamp and stretch the tape roll 21, and the cutter assembly 22 is configured to cut the stretched tape to form a first tape or a second tape.

[0080] During the tape feeding process, the tape roll 21 rotates and feeds the tape, while pneumatic grippers clamp the end of the tape and stretch it along the slide rail to a predetermined length. The cutter cylinder drives the blade to press down and cut the tape. Since the tape rolls 21 of the two mechanisms rotate in opposite directions, they can cut upward and downward tape surfaces respectively, meeting the requirements for top and bottom adhesive application of the tape.

[0081] like Figure 6 As shown, the first tape application mechanism 20 and the second tape application mechanism 30 also include a waste tape recycling component 24. The waste tape recycling component 24 includes a pressure roller 241 and a waste plate 242. The pressure roller 241 presses the waste tape onto the waste plate 242 to recycle the waste tape.

[0082] In this embodiment, the pressure roller 241 is driven by a cylinder, and the piston rod end is connected to the pressure roller 241. The waste plate 242 is a metal plate. Since the tape rolls 21 of the first tape application mechanism 20 and the second tape application mechanism 30 rotate in opposite directions, the waste plate 242 of the first tape application mechanism 20 is located above the pressure roller 241, and the waste plate 242 of the second tape application mechanism 30 is located below the pressure roller 241.

[0083] The cut waste tape is guided by pressure roller 241 to the waste plate 242. A cylinder drives pressure roller 241 to move, pressing the waste tape onto the waste plate 242 to prevent it from scattering. This device automatically collects waste, keeps the equipment clean, and reduces manual cleaning time.

[0084] like Figure 2 , 10 As shown in Figure 11, the automatic tape splicing device 100 also includes a cutting component 70, which includes a first fixing part 71, a second fixing part 72, and a cutting part 73. The first fixing part 71 and the second fixing part 72 both fix the first tape and / or the second tape. The cutting part 73 is located between the first fixing part 71 and the second fixing part 72 and cuts the connecting end of the first tape and / or the second tape so that the connecting end of the first tape and the second tape is aligned.

[0085] In this embodiment, both the first fixing part 71 and the second fixing part 72 are pneumatic upper and lower rollers, located on both sides of the cutting part 73. The cutting part 73 consists of a cylinder-driven blade, and the cutting direction is perpendicular to the extension direction of the strip.

[0086] Before the tape is attached, the upper and lower rollers on both sides of the first fixing part 71 and the second fixing part 72 clamp together to fix the first and second tapes. The blade of the cutting part 73 presses down to cut the connecting end of the tape, ensuring flatness and alignment. After cutting, the first fixing part 71 and the second fixing part 72 are released, and the tape continues to be conveyed in preparation for adhesive application.

[0087] The complete workflow of the automatic tape-connecting device 100 is as follows:

[0088] Material strip placement: Place the first material strip and the second material strip on the carrier guide rail 10. The first drive assembly 50 and the second drive assembly 60 drive the material strip to move. The cutting assembly 70 cuts the ends of the first material strip and / or the second material strip. After the ends are neatly arranged, bring the connecting ends of the first material strip and the second material strip closer and align them.

[0089] Tape preparation: The first tape application mechanism 20 is activated, the tape roll 21 feeds out the tape, and after being stretched to a predetermined length by the tape clamping assembly 23, it is cut by the cutter assembly 22 to form the first tape.

[0090] Tape transfer: The adhesive taking part 41 of the tape transfer mechanism 40 takes the first tape from the first tape application mechanism 20, and the adhesive transfer part 42 drives the adhesive taking part 41 to move along the slide rail to move the first tape to the application position 14.

[0091] Double-sided bonding: At the bonding position 14, the first tape is bonded to the lower surface of the connection end of the first and second material strips. The second tape bonding mechanism 30 is activated, and the tape roll 21 feeds out the tape. After being stretched to a predetermined length by the clamping assembly 23, the lifting mechanism 412 drives the vacuum suction cup 411 to move upward until the first tape is bonded to the first and second material strips. The vacuum suction cup 411 continues to move upward until the lower surface of the tape on the second tape bonding mechanism 30 is bonded to the first and second material strips. Then, the cutter assembly 22 of the first tape bonding mechanism 20 cuts to form the second tape. At this time, the first tape and the second tape are bonded to the upper and lower surfaces of the same position.

[0092] Connection complete: The first and second tapes firmly connect the first and second material strips together, forming a continuous material strip structure. The vacuum suction cup 411 stops adsorption, the lifting mechanism 412 returns to its initial position, and the waste tape recycling component 24 collects the excess tape.

[0093] Compared with the prior art, this embodiment has the following beneficial effects:

[0094] The automatic tape splicing device 100 achieves tape bonding on both sides of the first and second tapes, significantly enhancing the stability of the tape connection. The tape transfer mechanism 40, through its adhesive-taking part 41 and adhesive-transfer part 42, precisely moves the first tape to the bonding position 14 aligned with the second tape. The first and second tapes can then be bonded to their respective opposite sides at the bonding position 14, thus achieving a secure connection between the two tapes. Compared to traditional manual operation, this invention not only improves the accuracy and consistency of tape splicing but also reduces manual intervention, increasing production efficiency and providing a more reliable and efficient solution for tape splicing in semiconductor chip testing or processing.

[0095] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0096] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
