Description

Technical Field

[0001] This utility model relates to the field of chip mounting technology, specifically to an integrated chip substrate clamping and conveying mechanism and equipment. Background Technology

[0002] A surface mount technology (SMT) machine is a core automated equipment that mounts chips onto printed circuit boards (substrates) at high speed and with high precision. The equipment loads the substrate, preheats it, loads the chips, and then solders them at high temperature to form the product.

[0003] Effective substrate transport is a crucial step in the chip mounting process. Substrates come in various materials; some are strong enough to be moved along tracks by pushing, while others are thinner and more flexible, making them prone to jamming when pushed. Therefore, existing technologies use guide rails in conjunction with conveyor belts for transport. Although conveyor belts can handle the transport of these sheet-like, easily bent and deformable substrates, their posture control is difficult, significantly reducing operating efficiency, and the jamming problem remains unresolved. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an integrated chip substrate clamping and conveying mechanism and conveying equipment, which can effectively convey the substrate and keep the posture consistent, thus effectively solving the problem of material jamming.

[0005] To solve the above-mentioned technical problems, this utility model provides an integrated chip substrate clamping mechanism, including a horizontal base plate, a fixed vertical plate on the horizontal base plate, a first lifting frame and a second lifting frame respectively on the two side surfaces of the fixed vertical plate, a second driven wheel on the second lifting frame, a first driving wheel above the second driven wheel, the first driving wheel being connected to the first lifting frame, and a power motor on the first lifting frame, the power motor being connected to and driving the first driving wheel to rotate;

[0006] The fixed upright plate is also provided with a first lifting component and a second lifting component. The first lifting component drives the first lifting frame to move, and the second lifting component drives the second lifting frame to move.

[0007] Furthermore, there are two of each of the first driving wheel and the second driven wheel, arranged in a rectangular array, and adjacent first driving wheels are connected by a transmission rubber ring.

[0008] Furthermore, the first lifting assembly includes a first driving cam and a first tension spring. The first driving cam is connected to a first driving motor. One end of the first tension spring is connected to a fixed upright plate, and the other end is connected to a first lifting frame. A first abutting arm is provided on the first lifting frame. The first abutting arm abuts against the surface of the first driving cam through the first tension spring. A first lifting guide rail is provided between the first lifting frame and the fixed upright plate.

[0009] The second lifting assembly includes a second drive cam and a second tension spring. The second drive cam is connected to a second drive motor. Two ends of the second tension spring are connected to a fixed upright plate, and the other end is connected to a second lifting frame. A second abutting arm is provided on the second lifting frame. The second abutting arm abuts against the surface of the second drive cam through the second tension spring. A second lifting guide rail is provided between the second lifting frame and the fixed upright plate.

[0010] Furthermore, an auxiliary mounting bracket is provided on the fixed plate, and a motor mounting bracket is provided on the auxiliary mounting bracket. The first drive motor and the second drive motor are both fixedly mounted on the motor mounting bracket.

[0011] Furthermore, a rotational position sensor is provided on the motor mounting bracket.

[0012] Furthermore, the auxiliary mounting bracket is equipped with a lifting position sensor.

[0013] Furthermore, an extension arm is provided between the first drive wheel and the first lifting frame.

[0015] Furthermore, a guide rail is provided between the horizontal base plate and the fixed base plate, and a belt drive assembly is also provided on the fixed base plate. One side of the horizontal base plate is fixedly connected to the drive belt in the belt drive assembly.

[0016] The beneficial effects of this utility model are:

[0017] 1. The first driving wheel and the second driven wheel, which are divided into upper and lower sections, are used as a fixed base. With the first lifting frame and the second lifting frame, the substrate can be clamped between the two, effectively detached from the guide rail. The first driving wheel is driven by the power motor to rotate, so that the substrate can be actively output.

[0018] 2. The clamping and conveying mechanism, in conjunction with the long-distance conveying mechanism, can achieve the clamping and fixing of the substrate and the effects of long-distance and short-distance transportation. The transportation process does not rely on the guide rail to limit the substrate, and the movement is smooth and without jamming.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0026] Reference Figures 1 to 4 As shown, one embodiment of the integrated chip substrate clamping mechanism of this utility model includes a horizontal base plate 1, a fixed upright plate 2 on the horizontal base plate, a first lifting frame 3 and a second lifting frame 4 respectively on the two side surfaces of the fixed upright plate, a second driven wheel 5 on the second lifting frame, a first driving wheel 6 above the second driven wheel, the first driving wheel being connected to the first lifting frame, and a power motor 7 on the first lifting frame, the power motor being connected to and driving the first driving wheel to rotate; the fixed upright plate also has a first lifting assembly 8 and a second lifting assembly 9, the first lifting assembly driving the first lifting frame to move, and the second lifting assembly driving the second lifting frame to move. The first lifting frame and the second lifting frame move relative to each other, wherein when moving closer, they can clamp the substrate, and when moving further apart, they can release the substrate, thereby achieving the effect of gripping and fixing the substrate. The power motor can drive the first driving wheel to rotate, after clamping the substrate, the first driving wheel rotates, and in conjunction with the second driven wheel, the substrate can be moved forward or backward, i.e., short-distance transportation. For example, at a fixed position, the first driving wheel rotates, driving the substrate to move until the substrate disengages from the first driving wheel. At the moment of disengagement, the substrate stops moving. Therefore, the transport position of the substrate can be effectively determined, achieving accurate transport. The axles of the first driving wheel and the second driven wheel are both connected to the corresponding fixed positions via bearings. The axle of the first driving wheel is then connected to the power motor via a shaft connector.

[0027] Based on the aforementioned clamping and short-distance conveying functions, this application also provides a conveying device, such as... Figure 5 As shown, the clamping mechanism 113 described above is mounted on the fixed base plate 114. A guide rail 26 is provided between the horizontal base plate and the fixed base plate. A belt drive assembly 27 is also provided on the fixed base plate. One side of the horizontal base plate is fixedly connected to the drive belt in the belt drive assembly. The belt drive assembly can drive the pulley to rotate through a servo motor. The pulley drives the belt to rotate, and the rotation of the belt drives the horizontal base plate to move along the guide rail.

[0028] During operation, the substrate is held by a clamping mechanism, and then the belt drive assembly moves, causing the clamping mechanism to move, thus moving the substrate. Once in position, the clamping mechanism releases the substrate, placing it back on the guide rail for long-distance transport. However, due to the design of the transport connection structure, the current position after releasing the substrate does not guarantee its entry into the next process. Therefore, the first driving wheel and the second driven wheel work together to push the substrate forward, allowing it to enter the next process. Figure 5 As shown, the pushing process allows the substrate to be fed into the next clamping mechanism, completing the effective connection. Of course, it can also be in the next workstation.

[0029] Specifically, when using one first driving wheel and one second driven wheel, the clamping point is a single point on the substrate, which can cause deflection during movement. Therefore, the number of both the first driving wheel and the second driven wheel is set to two, arranged in a rectangular array, with two first driving wheels at the top and two second driven wheels at the bottom. During clamping, the two single points contact and clamp, ensuring stable movement. Adjacent first driving wheels are connected by a transmission rubber ring 10 to achieve synchronous rotation, which can be achieved with a single motor and provides good synchronization. An extension arm 25 is provided between the first driving wheel and the first lifting frame, allowing the first driving wheel to be mounted on one side of the second driven wheel.

[0030] The aforementioned first lifting assembly includes a first drive cam 11 and a first tension spring 12. The first drive cam is connected to a first drive motor 13. One end of the first tension spring is connected to a fixed vertical plate, and the other end is connected to a first lifting frame. A first abutting arm 14 is provided on the first lifting frame. The first abutting arm abuts against the surface of the first drive cam through the first tension spring. A first lifting guide rail 15 is provided between the first lifting frame and the fixed vertical plate. The first tension spring pulls the first lifting frame down from top to bottom, ensuring that the first abutting arm always abuts against the surface of the first drive cam. The first drive motor rotates, driving the first drive cam to rotate. Due to the cam surface structure, the first drive cam can push the first abutting arm closer to or away from the center point. With the cooperation of the first lifting guide rail, the first lifting frame can move along the guiding direction of the first lifting guide rail. The first lifting guide rail is vertically set, meaning that the first lifting frame can move up or down.

[0031] The second lifting assembly includes a second drive cam 16 and a second tension spring 17. The second drive cam is connected to a second drive motor 18. Two ends of the second tension spring are connected to a fixed vertical plate, and the other end is connected to a second lifting frame. A second abutting arm 19 is provided on the second lifting frame. The second abutting arm abuts against the surface of the second drive cam through the second tension spring. A second lifting guide rail 20 is provided between the second lifting frame and the fixed vertical plate. The second tension spring pulls the second lifting frame down from top to bottom, ensuring that the second abutting arm always abuts against the surface of the second drive cam. The second drive motor rotates, driving the second drive cam to rotate. Due to the cam surface structure, the second drive cam can push the second abutting arm closer to or away from the center point. With the cooperation of the second lifting guide rail, the second lifting frame can move along the guiding direction of the second lifting guide rail. The second lifting guide rail is vertically set, meaning that the second lifting frame can move up or down.

[0032] During the clamping process of the aforementioned clamping mechanism, the second driven wheel is rotated by the second drive cam, pressing the second abutment arm upward. At this time, the second tension spring is stretched and stores force, while the first driving wheel is rotated by the first drive wheel. This reduces the force on the first tension spring at the thin-walled position of the first abutment arm, causing the first tension spring to pull the first abutment arm downward. Consequently, the first driving wheel presses the substrate onto the second driven wheel. This method can be understood as the second driven wheel being held by the second drive cam, with no downward movement margin, while the first driving wheel abuts against the substrate surface through the tension of the first tension spring, allowing for upward movement. Therefore, it is applicable to substrates of different thicknesses.

[0033] By controlling the first drive motor and the second drive motor, the first drive wheel and the second drive wheel can move relative to each other. Of course, asynchronous movement can also be achieved in some necessary scenarios. A first abutting wheel 111 is provided on the first abutting arm, and a second abutting wheel 112 is provided on the second abutting arm, so that the friction at the contact point becomes rolling friction, ensuring the smooth rotation of the first drive cam and the second drive cam.

[0034] The aforementioned structure contains several components that require installation and fixation. To reduce the complexity of manufacturing the fixed support plate, an auxiliary mounting bracket 21 is provided on the fixed support plate. A motor mounting bracket 22 is mounted on the auxiliary mounting bracket, and both the first and second drive motors are fixedly mounted on the motor mounting bracket. This modular structure achieves a supportive installation effect.

[0035] A rotary position sensor 23 is installed on the motor mounting bracket to detect the rotational position of the cam. A lifting position sensor 24 is installed on the auxiliary mounting bracket to detect whether the first driving wheel and the second driven wheel have moved into position. For example, when clamping, the lifting position sensor needs to detect the signals after the first driving wheel and the second driven wheel move; when releasing, the lifting position sensor needs to lose the signals from both.

[0036] In the application scenarios of this application, refer to Figure 2 As shown, there are accommodating spaces between the first driving wheel and the extension arm, and between the second driven wheel and the second lifting frame. A track with a lateral opening is provided at this location. One side of the substrate is located in the lateral opening. The device clamps one side of the substrate and then moves and conveys it along the track. The track is an existing structure and will not be described in detail or shown in the figure.

[0037] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
