Description

Technical Field

[0001] This utility model belongs to the field of packaging equipment technology, and in particular relates to a heat sealing device for carrier packaging. Background Technology

[0002] Carrier tape is a plastic carrier used for packaging SMT electronic components such as ICs, resistors, inductors, capacitors, connectors, fuses, switches, relays, plugs, oscillators, and diodes / transistors. Current carrier tape packaging methods include cold sealing and heat sealing. Cold sealing requires pre-applying adhesive to the cover tape and then bonding it under pressure at room temperature. Heat sealing uses a heating element to heat the contact surfaces of the carrier tape and cover tape to a molten state, then applies pressure to fuse the molecular layers of the two materials, forming a permanent seal upon cooling. Heat sealing is widely used due to its superior sealing and moisture-proof performance; however, current heat sealing structures are complex, increasing equipment costs. Therefore, there is an urgent need to develop a heat sealing mechanism with a simple structure and low manufacturing cost. Utility Model Content

[0003] The purpose of this invention is to provide a heat-sealing device for carrier packaging, which aims to solve the technical problem of slow feeding speed in existing welding equipment.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A heat-sealing device for carrier tape packaging includes a heat-sealing knife and a mounting frame. The heat-sealing knife is disposed on the edge of the mounting frame and above a conveyor belt for conveying the carrier tape. The mounting frame is connected to a front-rear adjustment mechanism for adjusting the front-rear position of the heat-sealing knife. The front-rear adjustment mechanism is connected to a lifting mechanism for driving the heat-sealing knife to rise and release the cover tape from the carrier tape, and to descend and press the cover tape onto the carrier tape. The heat-sealing knife is used to heat the contact surface between the carrier tape and the cover tape.

[0006] Preferably, the mounting bracket is L-shaped, with its vertical portion connected to the heat sealing knife and its horizontal portion connected to the front and rear adjustment mechanism.

[0007] Furthermore, the vertical portion of the mounting bracket is connected to the heat sealing knife via a heat insulation plate.

[0008] Preferably, the heat sealing knife includes a heating cavity and a blade on its side, the blade being connected to the heating cavity by bolts, and an electric heating element being provided inside the heating cavity.

[0009] Preferably, the front and rear adjustment mechanism includes a mounting base, an adjusting screw, and a spring. The mounting base includes a vertical plate and a top plate connected in a T-shape. The horizontal part of the mounting frame is disposed on the top surface of the top plate. The rear end of the top plate is provided with a mounting block. The mounting block is connected to the rear side of the horizontal part of the mounting frame through the adjusting screw and the spring. There are two springs, which are symmetrically arranged on both sides of the adjusting screw. The connecting end of the adjusting screw is threadedly engaged with the threaded hole on the rear side of the horizontal part of the mounting frame. The force-applying end of the adjusting screw is connected to the mounting block.

[0010] Preferably, the force-applying end of the adjusting screw is provided with a nut, and the middle part of the mounting block is provided with an open mounting groove for accommodating the nut of the adjusting screw.

[0011] Preferably, the lifting mechanism includes a cylinder, a guide rail, and a slider that slides with the guide rail. The middle part of the slider is provided with a sliding groove that cooperates with the guide rail. The slider is fixed to the side of the upright plate. The guide rail and the cylinder body are both connected to the mounting plate. The end of the piston rod of the cylinder is connected to the upright plate.

[0012] Furthermore, the heat sealing device consists of two sets, with the heat sealing blades of the two sets symmetrically arranged on both sides of the carrier tape for simultaneously heat sealing both sides of the carrier tape.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention uses a front-to-back adjustment mechanism to adjust the position of the heat-sealing knife, and a lifting mechanism to adjust the lifting of the mounting frame and the heat-sealing knife. When the heat-sealing knife descends, it firmly presses the cover tape and carrier tape together, fusing them together. When the heat-sealing knife rises, it loosens the carrier tape, allowing it to move with the conveyor belt. Through the coordinated lifting of the conveyor belt and the heat-sealing knife, continuous heat sealing of the carrier tape is achieved, improving production efficiency. This invention has the advantages of simple structure, low manufacturing cost, convenient and quick operation, simplifies the structure of heat-sealing equipment, and greatly reduces equipment costs.

[0022] Furthermore, those skilled in the art should understand that the accompanying drawings are provided only to illustrate the purpose, features, and advantages of the present invention, and are not actually drawn to scale.

[0023] Furthermore, unless the context explicitly requires it, the words "comprising," "including," and similar terms throughout the specification and claims should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to."

[0024] like Figure 1 As shown in the figure, the heat sealing device for carrier tape packaging provided in this embodiment of the utility model includes a heat sealing knife 1 and a mounting frame 2. The heat sealing knife 1 is disposed on the edge of the mounting frame 2 and above the conveyor belt (not shown in the figure) used for conveying the carrier tape. The mounting frame 2 is connected to a front and rear adjustment mechanism, which is used to adjust the front and rear position of the heat sealing knife 1. The front and rear adjustment mechanism is connected to a lifting mechanism, which is used to drive the heat sealing knife 1 to rise and loosen the cover tape from the carrier tape, and to descend and press the cover tape onto the carrier tape. The heat sealing knife 1 is used to heat the contact surface between the carrier tape and the cover tape to achieve the packaging of the carrier tape.

[0025] As a preferred structure, such as Figure 1 As shown, the mounting bracket 2 is L-shaped. The vertical portion of the mounting bracket 2 is connected to the heat-sealing knife 1, and the horizontal portion is connected to the front and rear adjustment mechanism. The vertical portion of the mounting bracket is connected to the heat-sealing knife 1 via a heat insulation plate 3. The heat insulation plate can be a vacuum heat insulation plate or a polyurethane foam board, which can prevent heat transfer from the heat-sealing knife to the mounting bracket, thus improving the heat-sealing quality.

[0026] In specific embodiments of this utility model, such as Figure 2As shown, the heat-sealing knife 1 includes a heating cavity 11 and a blade 12 on its side. The blade 12 is connected to the heating cavity 11 by bolts. An electric heating element is provided inside the heating cavity 11. In this embodiment, the electric heating element is an electric heating rod, which heats the heating cavity and then transfers the heat to the blade. The blade can be adjusted according to the size of the carrier tape, making it flexible and convenient to use.

[0027] In specific embodiments of this utility model, such as Figure 1 As shown, the front-to-back adjustment mechanism includes a mounting base 4, an adjusting screw 5, and a spring 6. The mounting base 4 includes a vertical plate 41 and a top plate 42 connected in a T-shape. The horizontal part of the mounting frame 2 is disposed on the top surface of the top plate 42. A mounting block 43 is provided at the rear end of the top plate 42. The mounting block 43 is connected to the rear side of the horizontal part of the mounting frame 2 via the adjusting screw 5 and the spring 6. There are two springs 6, symmetrically arranged on both sides of the adjusting screw 5. The connecting end of the adjusting screw 5 is threaded into a threaded hole on the rear side of the horizontal part of the mounting frame 2, and the force-applying end of the adjusting screw 5 is connected to the mounting block 43. By rotating the adjusting screw, the distance between the horizontal part of the mounting frame and the mounting block can be adjusted, thereby adjusting the front-to-back position of the heat sealing knife.

[0028] In specific manufacturing, the force-applying end of the adjusting screw 5 is provided with a nut 50, and the middle of the mounting block 43 is provided with an open mounting groove to accommodate the nut 50 of the adjusting screw 5. During processing, a notch is machined on the edge of the mounting block to communicate with the mounting groove. A wrench that mates with the hexagonal socket of the nut can apply torque to the adjusting screw through the notch, facilitating the adjustment of the front and rear positions of the heat-sealing knife. At the same time, in order to meet the requirements of lightweight design, multiple elongated light-reducing grooves are designed on the horizontal part of the mounting base. The end of the adjusting screw passes through the threaded hole on the side wall of the light-reducing groove and extends into the light-reducing groove.

[0029] In specific embodiments of this utility model, such as Figure 1 , 2 As shown, the lifting mechanism includes a cylinder 7, a guide rail 8, and a slider 9 that slides with the guide rail 8. The slider 9 has a groove in its middle that mates with the guide rail 8. The slider 9 is fixed to the side of the upright plate 41. The guide rail 8 and the cylinder body of the cylinder 7 are both connected to the mounting plate 10. The piston rod end of the cylinder 7 is connected to the upright plate 41. During heat sealing, the cylinder drives the mounting base to descend, causing the heat sealing blade to press against the contact surface of the cover tape and the carrier tape. The heat from the heat sealing blade melts and bonds the two together. After heat sealing is completed, the cylinder drives the mounting base and the heat sealing blade to rise, allowing the heat-sealed carrier tape to move forward with the conveyor belt.

[0030] In practical applications, the heat sealing device is designed as two sets, with the heat sealing blades 1 of the two sets of heat sealing devices symmetrically arranged on both sides of the carrier tape, for simultaneously heat sealing both sides of the carrier tape.

[0031] In summary, this invention has the advantages of simple structure and low manufacturing cost. The front and rear positions of the heat-sealing knife can be adjusted by adjusting the screw, and the lifting and lowering of the heat-sealing knife is driven by a cylinder, enabling the movement and heat sealing of the carrier belt. The cooperation between the conveyor belt and the automatically lifting heat-sealing knife achieves continuous heat-sealing and packaging of the carrier belt, improving production efficiency. This invention simplifies the structure of heat-sealing equipment, makes operation convenient and quick, and is easy to manufacture, greatly reducing equipment costs.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
