Description

Technical Field

[0001] This invention belongs to the technical field of carrier tape splicing devices, specifically relating to a linkage heating and bonding device. Background Technology

[0002] During the operation of a pick and place machine, carrier tape is usually used for feeding. The carrier tape is wound on a trolley. When there is not much carrier tape left on a trolley, the tail of the carrier tape on the old trolley needs to be joined and bonded to the head of the carrier tape on a new trolley. After the joining is completed, the new trolley continues to feed the material.

[0003] The current carrier tape splicing method involves aligning the pre-cut carrier tape head with the carrier tape tail, then attaching adhesive tape to the upper surface of the carrier tape, and finally bending the side of the adhesive tape protruding from the carrier tape to wrap around the edge, thus completing the adhesion between the adhesive tape and the carrier tape. However, for existing semi-automatic or fully automatic carrier tape splicing devices, the final step only involves bending and bending the adhesive tape again to attach it to the lower surface of the carrier tape. The lack of a pressing operation to firmly adhere the adhesive tape to the lower surface of the carrier tape leads to poor adhesion, which in turn affects the chip feeding. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a linkage heating and bonding device to solve the technical problem that the current material splicing device lacks the operation of pressing the adhesive paper firmly onto the lower surface of the carrier tape, which leads to poor splicing and bonding reliability.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: a linkage heating and bonding device, comprising a bonding base, an adhesive tape picking mechanism, and a linkage drive mechanism. The adhesive tape picking mechanism includes an adhesive tape suction head and a vertical blade. The bonding base includes a material channel bonding position and a horizontal blade. The linkage drive mechanism drives the adhesive tape picking mechanism to pick up the adhesive tape and deliver it to the material channel bonding position to bond it to the first side of the carrier belt. The mechanism also drives the vertical blade to bend the adhesive tape vertically. The linkage drive mechanism drives the horizontal blade to bend the bent portion of the adhesive tape vertically, so that the bent portion of the adhesive tape is bonded to the second side of the carrier belt. Finally, the linkage drive mechanism drives the horizontal blade to press the bent portion of the adhesive tape towards the carrier belt. The linkage drive mechanism is powered by a single power source.

[0006] Preferably, the adhesive tape pickup mechanism includes a pickup support, the adhesive tape suction head is elastically connected to the pickup support, and the vertical blade is fixedly connected to the pickup support.

[0007] Preferably, the adhesive tape suction head is a heated suction head.

[0008] Preferably, the linkage drive mechanism includes a motor, a first gear connected to the motor, a first rack meshing with the first gear, a first cam driven by the first rack, a second rack, a second gear meshing with the second rack, and a second cam driven by the second gear; The linkage drive mechanism further includes a drive plate with a zigzag cam groove that moves synchronously with the first rack. The first cam is slidably connected in the cam groove and is connected to the second rack to drive the second rack to move synchronously. During the meshing of the first gear and the first rack, the first cam slides in the cam groove and drives the second rack to perform horizontal reciprocating motion. The linkage drive mechanism also includes a guide plate with an inverted U-shaped groove. The second cam is slidably connected in the U-shaped groove. The second cam is connected to the pickup support. The second gear drives the second cam to slide in the U-shaped groove, thereby driving the pickup support to complete the inverted U-shaped swing.

[0009] Preferably, the cam groove includes an inclined groove and a vertical groove connected to the end of the inclined groove.

[0010] Preferably, the linkage drive mechanism further includes a lower pressure plate connected to the drive plate, used to drive the transverse cutter to bend and press the adhesive paper.

[0011] Preferably, the bonding base further includes a transverse knife support and a sliding member connecting the transverse knife support and the transverse knife; the transverse knife support is supported by a slide rail and can move away from / approach the material channel bonding position; the sliding member can slide relative to the transverse knife support, driving the transverse knife away from / approach the second side of the carrier belt.

[0012] Preferably, an elastic element is provided between the transverse knife support and the slide rail, and the elastic element has a spring force that pushes the transverse knife support toward the material channel contact position.

[0013] Preferably, the bonding base further includes a wedge block disposed below the bonding position of the material channel; the wedge block is slidably connected to the bonding base, and the wedge block is driven to move up and down by the lower pressure plate; the wedge block cooperates with the inclined surface provided on the transverse knife support, and during the up and down movement of the wedge block, in conjunction with the action of the elastic element, the wedge block drives the transverse knife support to move along the slide rail.

[0014] Preferably, the fitting base further includes a lever, one end of which is connected to a wedge block, and the other end extends below the sliding member.

[0015] The beneficial effects of adopting the technical solution of this invention are as follows: This invention includes a vertical blade and a horizontal blade. The vertical blade bends the adhesive tape adhered to the upper surface of the carrier tape, and the horizontal blade bends the bent portion of the adhesive tape again towards the lower surface of the carrier tape. The horizontal blade also presses upward to firmly adhere the adhesive tape to the lower surface of the carrier tape, improving adhesion and stability, and enhancing the reliability of the material connection. Both the vertical and horizontal blades are driven by a linkage drive mechanism, which is powered by a single power source. The entire driving process is coordinated by a single linkage system and powered by a single power source. This single power source allows for better control of the entire material connection process and results in a more compact structure. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments, and do not limit the scope of the present invention.

[0019] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] The specific implementation method is as follows: Example 1, as Figures 1-7 As shown, a linkage heating and bonding device is provided, which includes a bonding base 1, an adhesive paper picking mechanism 2, and a linkage drive mechanism 3.

[0022] The bonding base 1 includes a material channel bonding position 11, a transverse knife 12, a sliding member 13, a transverse knife support 14, a slide rail 15, a wedge block drive rod 16, a lever member 17, a connecting rod 18, and a wedge block 19.

[0023] Specifically, the material channel mating position 11 supports the mated tail and head of the carrier belt; the upper and lower parts of the material channel mating position 11 are empty to facilitate material receiving. A wedge block 19 is positioned below the material channel mating position 11 and can slide up and down relative to the mating base 1. The inclined surface of the wedge block 19 engages with the inclined surface on the transverse knife support 14. The transverse knife support 14 is connected to a slide rail 15 on the mating base 1, and the transverse knife support 14 reciprocates on the slide rail 15 to move away from / close to the material channel mating position 11. An elastic element is provided between the slide rail 15 and the transverse knife support 14. When no external force is applied to the transverse knife support 14, the elastic element has a spring force that drives the transverse knife support 14 closer to the material channel mating position 11. It should be noted that the elastic element can be reasonably positioned between the transverse knife support and the slide rail according to the specific structure. Thus, when the wedge block 19 moves upward, the inclined surfaces between the wedge block 19 and the transverse knife support 14 cooperate with each other, driving the transverse knife support 14 to move along the slide rail 15 away from the material channel contact position 11; when the wedge block 19 moves downward, under the action of the elastic force of the elastic element, it drives the transverse knife support 14 to move along the slide rail 15 closer to the material channel contact position 11.

[0024] More specifically, the slider 13 passes through a sliding hole vertically set on the transverse knife support 14. The upper end of the slider 13 is connected to the transverse knife 12, and the lower end of the slider 13 extends below the transverse knife support 14. The slider 13 moves up and down, causing the transverse knife 12 to move up and down. One end of the lever 17 is connected to the wedge block 19 via the connecting rod 18, and the other end extends below the slider 13. In this way, after the transverse knife support 14 drives the transverse knife 12 to be below the carrier belt, the end of the lever 17 away from the connecting rod 18 is directly below the slider 13. The wedge block 19 drives the end of the lever 17 near the connecting rod 18 downward, and the end of the lever 17 away from the connecting rod 18 pushes the slider 13 upward. The slider 13 drives the transverse knife 12 to push the adhesive tape upward, improving the adhesion of the adhesive tape to the carrier belt, making the carrier belt less likely to break when receiving material.

[0025] The adhesive tape pickup mechanism 2 includes a pickup support 21, an adhesive tape suction head 22, and a vertical blade 23.

[0026] Specifically, the adhesive tape suction head 22 is elastically connected to the pickup support 21 via springs, spring sheets, and resilient rubber blocks, allowing the adhesive tape suction head 22 to move up and down relative to the pickup support 21 within a certain limit. The vertical cutter 23 is fixedly connected to the pickup support 21 and can only move synchronously with the pickup support 21. In this way, the adhesive tape pickup mechanism 2 picks up the adhesive tape through the adhesive tape suction head 22 and moves the adhesive tape to the bonding position 11 in the feed channel to adhere it to the upper surface of the carrier belt. As the adhesive tape pickup mechanism 2 continues to move downward, the elastic connection causes the adhesive tape suction head 22 to abut against the carrier belt and stop moving. The pickup support 21 then drives the vertical cutter 23 to continue moving downward, and the vertical cutter 23 vertically bends the edge of the adhesive tape that is protruding from the carrier belt downward.

[0027] In this embodiment, the adhesive tape suction head 2 is a vacuum suction head with heating function, which heats and wraps the edges of the carrier tape joint to ensure a firm fit and prevents it from breaking.

[0028] The linkage drive mechanism 3 includes a first gear 31, a first rack 32, a drive plate 33, a lower pressure plate 34, a first cam 38, a second rack 35, a second gear 36, a guide plate 37, a first cam 38, a lever 39, a second cam 310, and a motor 311.

[0029] Specifically, the motor 311, the second gear 36, and the guide plate 37 are fixedly mounted on the drive support, while the first rack 32, the drive plate 33, the first cam, the second rack 35, and the second cam are movably connected to the drive support. The motor 311 is connected to the first gear 31, and the first rack 32 is fixedly connected to the drive plate 33. Under the meshing action of the first gear 31 and the first rack 32, the first rack 32 and the drive plate 33 can slide up and down relative to the drive support. The drive plate 33 is provided with a zigzag-shaped cam groove 331.

[0030] In this embodiment, the cam groove is a polygonal type comprising a vertical groove in the shape of a "|" and an oblique groove in the shape of a "﹨", with the vertical groove connected to the upper end of the oblique groove.

[0031] More specifically, a first cam 38 is provided on the side of the drive plate 33 away from the first rack 32. One end of the first cam 38 is placed in the cam groove 331, and the other end is fixedly connected to the second rack 35. In this way, the first gear 31 is driven by the motor 311, and the first rack 32, which meshes with the first gear 31, drives the drive plate 33 to move up and down. During this process, the first cam 38 slides in the cam groove 331. When the first cam 38 is in the inclined groove of the cam groove 331, the up-and-down moving drive plate 33 drives the first cam 38 to move horizontally, and then the first cam 38 drives the second rack 35 to move horizontally. When the first cam 38 is in the vertical groove of the cam groove 331, the horizontal position of the first cam 38 no longer changes.

[0032] More specifically, the horizontal movement of the second rack 35 drives the second gear 36 to rotate in both directions. The guide plate 37 is located on the side of the second gear 36 away from the drive plate 33, and an inverted U-shaped groove 371 is provided on the guide plate 37. The shaft connected to the second gear 36 passes vertically through the guide plate 37, and a lever 39 is vertically connected to the end of the shaft that passes through the guide plate 37. An elongated groove is provided on the lever 39 near the movable end. The second cam 310 passes through the elongated groove, and one end of the second cam 310 is slidably connected in the U-shaped groove 371, while the other end is connected to the pickup support 21. In this way, the second rack 35 drives the second gear 36 to rotate during horizontal movement, and the second gear 36 drives the lever 39 to rotate. The second cam 310, which passes through the elongated hole on the lever 39, is driven to move by the lever 39. During the process, due to the cooperation between the U-shaped groove 371 and the elongated hole, the second cam 310 moves back and forth along the U-shaped groove 371. In turn, the second cam 310 drives the pickup support 21 to complete the inverted U-shaped reciprocating swing, thereby realizing the pickup of the adhesive paper and the adhesion of the adhesive paper to the carrier belt.

[0033] In this embodiment, when the linkage heating and bonding device is in use, the linkage drive mechanism 3, under the power output of the motor 311, drives the adhesive paper picking mechanism 2 to move to the adhesive paper storage location and picks up the adhesive paper through the adhesive paper suction head 22. After picking up the adhesive paper, the motor 311 rotates in the reverse direction, and the first gear 31 drives the first rack 32 and the drive plate 33 to move downward. At this time, the first cam 38 slides in the inclined groove, thereby driving the first cam 38 to move horizontally in one direction. The first cam 38 drives the second rack 35 to move horizontally. Under the meshing action, the second rack 35 drives the second gear 36 to rotate, and the second gear 36 drives the lever 39 to rotate. The second cam 310, passing through the lever 39, is inverted under the action of the cooperation of the elongated hole and the U-shaped groove 371. The U-shaped path moves, and then the second cam drives the adhesive tape pickup mechanism 2 to complete the inverted U-shaped swing, which moves the adhesive tape to the feed channel bonding position 11 and sticks it to the upper surface of the carrier belt. At the end of the U-shaped swing of the adhesive tape pickup mechanism 2, the adhesive tape suction head 22 abuts against the carrier belt. The adhesive tape pickup mechanism 2 continues to move downward. The adhesive tape suction head 22 no longer moves downward because it is elastically connected to the pickup support 21. The vertical cutter 23 continues to move downward to vertically bend the adhesive tape protruding from the carrier belt. When the vertical cutter 23 completes the process of bending the adhesive tape, the first cam 38 enters the vertical groove from the inclined groove (when the first cam 38 slides in the vertical groove, the first cam 38 and the second rack 35 no longer move horizontally, and at this time the adhesive tape picking mechanism 2 presses against the material channel bonding position 11). At this time, the lower pressure plate 34 abuts against the wedge block drive rod 16, the motor 311 continues to rotate, and the drive plate 33 drives the wedge block drive rod 16 to continue to descend. The wedge block 19 moves downward. Due to the cooperation of the inclined surfaces between the wedge block 19 and the transverse cutter support 14, and the elastic force of the elastic element between the transverse cutter support 14 and the slide rail 15, the transverse cutter support 14 carries the transverse cutter 12 and moves horizontally toward the material channel bonding position 11. During the horizontal movement of the transverse cutter 12, the bent portion of the adhesive tape is bent again, adhering the bent portion of the adhesive tape to the lower surface of the carrier belt. When the adhesive tape is adhered to the lower surface of the carrier belt, the inclined surface of the transverse cutter support 14 and the wedge block 19 disengage, the horizontal movement of the transverse cutter support 14 ends, and the end of the lever 17 is directly below the slider 13. The wedge block 19 continues to move downward, pressing the other end of the lever 17 downward through the connecting rod 18, causing the end of the lever 17 directly below the slider 13 to tilt upward and push the slider 13. The slider 13 drives the transverse cutter 12 upward to press the adhesive tape firmly against the lower surface of the carrier belt, improving the reliability of the adhesion to the carrier belt and reducing the occurrence of breakage. At this point, the process of picking up the adhesive tape and attaching it to the carrier belt is completed. After the motor 311 turns again, the process of the adhesive tape picking mechanism 2 moving from the feed channel bonding position 11 to the adhesive tape storage position is completed.

[0034] The bonding process of the carrier tape is powered by only one power source, motor 311, which not only enables the control of the entire feeding process, but also makes the whole structure more compact and saves space.

[0035] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
