Description

Technical Field

[0001] This application relates to the field of surface mount component processing, specifically to an SMT surface mount carrier tape. Background Technology

[0002] In the SMT (Surface Mount Technology) production process, surface mount carrier tapes are widely used to carry and transport electronic components. Traditional SMT carrier tapes typically employ a fixed-height carrier slot design, with components placed within the slot and mounted by automated equipment. However, this fixed-height design has certain limitations: if the component is too tightly fitted into the slot, it becomes difficult to remove; especially when manually picking up and placing components, the operation efficiency is low; and using a vacuum nozzle to pick up components can easily damage them. Utility Model Content

[0003] The purpose of this utility model is to provide an SMT placement carrier tape to solve the problems of difficult component placement, low operating efficiency, and easy component damage caused by the fixed height bearing groove of traditional SMT placement carrier tapes in the prior art. To achieve the above objective, this application provides the following technical solution: an SMT placement carrier tape, comprising:

[0004] Baseband, the surface of which is arrayed with bearing grooves;

[0005] A through hole is provided in the side wall of the baseband and penetrates the bearing groove;

[0006] The lifting mechanism, disposed within the bearing groove, includes a support plate, a cross-hinged assembly, a guide structure, a screw, and a base plate.

[0007] The support plate is disposed within the bearing groove to support the component;

[0008] The cross-hinged assembly is disposed between the base plate and the support plate, and consists of two sets of X-shaped hinge members. Each set of hinge members includes a first hinge arm and a second hinge arm, and the two sets of X-shaped hinge members are connected by a central hinge shaft.

[0009] The upper ends of the two sets of first hinge arms are respectively hinged to both ends of the long horizontal shaft and the lower ends are hinged to both ends of the adjusting shaft. The long horizontal shaft is connected to the support plate, and the adjusting shaft is provided with an internal thread hole that is threaded with the screw.

[0010] The lower ends of both sets of second hinge arms are hinged to the short horizontal shaft, and the upper ends are hinged to both ends of the rotating shaft. The short horizontal shaft is fixedly connected to the base plate.

[0011] Two guide structures, respectively located on the opposite surfaces of the support plate and the base plate, respectively accommodate the rotating shaft and the adjusting shaft to constrain the sliding trajectory of the rotating shaft and the adjusting shaft;

[0012] The screw is disposed in the through hole and passes through the internal threaded holes of several adjusting shafts. By rotating the screw, the adjusting shafts are driven to move axially, forcing the cross hinge assembly to unfold or retract, thereby driving the support plate to rise and fall in the vertical direction.

[0013] In a preferred embodiment, the present technical solution further includes a protrusion, which is disposed at the middle position of the adjustment shaft.

[0014] In a preferred embodiment of this technical solution, the guide structure consists of a limiting plate and connecting rods disposed at both ends of the limiting plate.

[0015] In a preferred embodiment of this technical solution, at least one end of the screw extends to the side of the baseband, and this end is provided with an anti-slip knob.

[0016] In a preferred embodiment of this technical solution, the surface of the anti-slip knob is provided with radial grooves distributed at equal angles.

[0017] In a preferred embodiment, this technical solution also includes a relief groove, which is disposed in the middle of the base plate and corresponds to the movement path of the protrusion.

[0018] In a preferred embodiment, this technical solution further includes a reinforcing plate, which connects two sets of the first hinge arms or two sets of the second hinge arms.

[0019] Compared with the prior art, the beneficial effects of this application are:

[0020] This invention, by incorporating a lifting mechanism, allows for flexible adjustment of the support slot height based on component size and operational requirements. This effectively prevents components from fitting too tightly into the support slot, facilitating component handling in both automated and manual processes and significantly improving operational efficiency. The interlocking components, guide structure, and screw within the lifting mechanism work together to ensure smoother and more precise movement of the support plate during lifting, thereby guaranteeing component stability within the support slot. This contributes to improved SMT placement accuracy and reduces placement defects caused by component misalignment. Attached Figure Description

[0030] In order to solve the technical problems in the background art, such as Figure 1-4 As shown, this application provides a technical solution: an SMT placement carrier tape, characterized as follows:

[0031] The baseband 1 is the fundamental component of the entire carrier tape, with bearing grooves 2 arranged in an array on its surface for supporting the patch element. Through holes 3 are located on the side wall of the baseband 1 and penetrate the bearing grooves 2. The through holes 3 provide installation and operating space for the screw 8 in the lifting mechanism 4, allowing the screw 8 to pass through the through holes 3 and cooperate with other components of the lifting mechanism 4 to achieve the lifting function of the support plate 5. The lifting mechanism 4 is the core component of this invention, located within the bearing grooves 2, and includes the support plate 5, a cross-hinged assembly 6, a guide structure 7, the screw 8, and a base plate 9. The support plate 5 is located within the bearing grooves 2, directly contacting the patch element and supporting it. Its position is above the cross-hinged assembly 6. The cross-hinged assembly 6 is located between the base plate 9 and the support plate 5 and consists of two sets of X-shaped hinges. Each set of hinges includes a first hinge arm 10 and a second hinge arm 11. The two sets of X-shaped hinges are connected by a central hinge shaft 12, forming a stable double-layer X-shaped structure. The upper ends of the two sets of first hinge arms 10 are respectively hinged to both ends of the long horizontal shaft 13, and the lower ends are hinged to both ends of the adjusting shaft 14, forming a rectangular structure. The long horizontal shaft 13 is connected to the support plate 5, and the adjusting shaft 14 has an internal threaded hole that mates with the screw 8. The lower ends of the two sets of second hinge arms 11 are both hinged to the short horizontal shaft 15, and the upper ends are hinged to both ends of the rotating shaft 16, forming a rectangular structure with a notch in the middle. The short horizontal shaft 15 is fixedly connected to the base plate 9. Through this hinge method, the cross-hinged assembly 6 can convert the rotational motion of the screw 8 into the lifting motion of the support plate 5. Two guide structures 7 are respectively provided on the opposite surfaces of the support plate 5 and the base plate 9, which respectively accommodate the rotating shaft 16 and the adjusting shaft 14, and are used to constrain the sliding trajectory of the rotating shaft 16 and the adjusting shaft 14. During the lifting process, the guide structure 7 ensures that the rotating shaft 16 and the adjusting shaft 14 slide along a predetermined path, ensuring the motion stability of the cross-hinged assembly 6 and the lifting accuracy of the support plate 5. The screw 8 is installed in the through hole 3 and passes through the internal threaded holes of several adjusting shafts 14. One end of the screw 8 can be driven to rotate by a motor or other power device. When the screw 8 rotates, since the adjusting shaft 14 has an internal threaded hole that is threaded to the screw 8, the adjusting shaft 14 will move along the axial direction of the screw 8 under the action of the thread, thereby driving the cross-hinged assembly 6 to unfold or retract, realizing the vertical lifting and lowering of the support plate 5. The base plate 9 is fixed in the bearing groove 2, serving as the supporting foundation of the cross-hinged assembly 6 and providing a stable installation platform for the entire lifting mechanism 4.

[0032] Furthermore, it also includes a protrusion 17, which is disposed at the middle position of the adjusting shaft 14. The protrusion 17 enhances the structural strength of the adjusting shaft 14, prevents the adjusting shaft 14 from bending or deforming during the rotation of the screw 8, and ensures the stability and reliability of the adjusting shaft 14.

[0033] Furthermore, the guide structure 7 consists of a limiting plate 18 and connecting rods 19 disposed at both ends of the limiting plate 18. The limiting plate 18 is a major component of the guide structure 7. The limiting plate 18 is disposed on the opposite surfaces of the support plate 5 and the base plate 9. Both ends of the limiting plate 18 are fixed to the support plate 5 and the base plate 9 by the connecting rods 19 to ensure its stable position. It is used to constrain the sliding trajectory of the rotating shaft 16 and the adjusting shaft 14. The length and width of the limiting plate 18 are designed according to the dimensions of the rotating shaft 16 and the adjusting shaft 14 to ensure that it can effectively limit the sliding range of the shafts. The connecting rods 19 are disposed at both ends of the limiting plate 18 to fix the limiting plate 18 to the support plate 5 and the base plate 9.

[0034] Furthermore, at least one end of the screw 8 extends to the side of the base band 1, and the other end is located in the bearing groove 2, engaging with the internal threaded hole of the adjusting shaft 14. An anti-slip knob 20 is located at the end of the screw 8, on the side of the base band 1. The anti-slip knob 20 is typically made of rubber or plastic, with an anti-slip texture on its surface to facilitate manual rotation of the screw 8. The anti-slip knob 20 is connected to the screw 8 via a threaded connection, snap-fit, or other fixing method to ensure its secure and reliable connection. By rotating the anti-slip knob 20, the rotation of the screw 8 can be easily controlled, thereby driving the adjusting shaft 14 to move axially, achieving the lifting and lowering of the support plate 5.

[0035] Furthermore, the surface of the anti-slip knob 20 has radial grooves distributed at equal angles. The design of these radial grooves significantly improves the anti-slip performance of the anti-slip knob 20, making it more stable and effortless for the operator to rotate. The radial grooves are distributed at equal angles on the surface of the anti-slip knob 20, typically in a V-shape or U-shape. These grooves not only increase the friction on the surface of the anti-slip knob 20 but also guide the direction of finger force, making rotational operation smoother.

[0036] Furthermore, it also includes a relief groove 21, which is disposed in the middle of the base plate 9 and corresponds to the movement path of the protrusion 17. The relief groove 21 is a recess in the middle of the base plate 9, and its shape and size are designed according to the shape and movement path of the protrusion 17. The relief groove 21 is provided to avoid interference between the protrusion 17 and the base plate 9 during movement, ensuring that the protrusion 17 can move smoothly on the base plate 9. The protrusion 17 moves along the relief groove 21 under the drive of the adjusting shaft 14, ensuring that its movement trajectory is not obstructed by the base plate 9.

[0037] Furthermore, the reinforcing plate 22 connects the two sets of first hinge arms 10 or the two sets of second hinge arms 11. The reinforcing plate 22 is a component used to enhance the stability of the cross-hinged assembly 6, and its shape and size are designed according to the structure of the first hinge arms 10 and the second hinge arms 11. The reinforcing plate 22 is typically a metal plate or a high-strength plastic plate, possessing sufficient strength and rigidity. The installation of the reinforcing plate 22 significantly enhances the overall stability of the cross-hinged assembly 6, preventing excessive deformation or swaying of the first hinge arms 10 and the second hinge arms 11 during lifting, thereby improving the operating accuracy and reliability of the lifting mechanism 4.

[0038] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
