Description

Technical Field

[0001] This utility model relates to the field of chip packaging technology, specifically to a track conveying device used in a SIP mounting machine. Background Technology

[0002] SIP (Surface Mount Technology) mounting machines are devices used to solder and package substrates and chips together. They include a substrate transport mechanism, which is mainly used to transport the substrate to be soldered from the loading area of ​​the mounting machine to the soldering station, and to transport the substrate to the unloading area after soldering is completed.

[0003] Currently, traditional SIP placement machine track conveyor systems mostly use actively powered track conveyor systems, consisting of two opposing tracks, both of which move the substrate via belts. This structure has the following main problems:

[0004] 1. When the previous substrate is being soldered at the soldering station, the next substrate must wait for the previous substrate to finish soldering and leave the station before it can enter, resulting in poor continuity of the entire production process and difficulty in improving production efficiency.

[0005] 2. The belt has a certain degree of flexibility, which results in insufficient precision when positioning the substrate. The substrate is prone to displacement and shaking during transportation, affecting the accuracy of subsequent welding processes and requiring repositioning and adjustment. Furthermore, the substrate contains both rigid and semi-flexible materials. The rigid material is heavy and requires high belt tension, while the semi-flexible material, although lightweight, is prone to jamming during transport.

[0006] Therefore, a non-powered track structure was designed, which serves as a guide channel, using a clamping method to slide the substrate within the guide channel. However, since the track requires support at at least both ends, and considering the characteristics of the sheet-mounted substrate, clamping needs to be applied to both the upper and lower surfaces of the substrate. This causes the support components to interfere with the clamping mechanism. The connection between preceding and following processes means that the clamping mechanism cannot meet the full-size movement of the current track. Furthermore, if this clamping mechanism is used for both temporarily stored and temporarily transferred substrates, it will significantly increase the waiting time. Therefore, there is an urgent need to develop a track device with auxiliary conveying capabilities. Summary of the Invention

[0007] The technical problem to be solved by this utility model is to provide a track conveying device used in a SIP mounting machine, which can independently feed and discharge materials at both ends of a non-powered guide track, reducing waiting time and improving production efficiency.

[0008] To solve the above-mentioned technical problems, this utility model provides a track conveying device used in a SIP mounting machine, including two parallel unpowered guide tracks. Limiting grooves are formed on the corresponding surfaces of the two unpowered guide tracks. A material clamping and moving component is provided on one side of one of the unpowered guide tracks, and a temporary storage feeding power component and a temporary storage discharging power component are respectively provided at both ends of the other unpowered guide track. The temporary storage feeding power component conveys the substrate to a fixed feeding position, and the temporary storage discharging power component transfers the substrate at the fixed position to the next process.

[0009] The temporary feeding power assembly includes a lower driving wheel and an upper driven wheel. A clearance section is provided on the unpowered guide track between the lower driving wheel and the upper driven wheel. The lower driving wheel is connected to the drive motor and fixed in position. The upper driven wheel is mounted on a swing mechanism. The swing mechanism drives the upper driven wheel to move toward or away from the lower driving wheel.

[0010] Furthermore, the swing mechanism includes a mounting frame and a swing arm. One end of the swing arm is shaft-connected to the mounting frame, and the other end is connected to the upper driven wheel and is provided with a lower pressure plate. The middle part of the swing arm is connected to the mounting frame through a tension spring. A lower pressure cylinder is also provided on the mounting frame. The telescopic rod of the lower pressure cylinder abuts against the lower pressure plate. The lower pressure cylinder is used to push the upper driven wheel to move toward the lower driving wheel, and the tension spring is used to move the upper driven wheel away from the lower driving wheel.

[0011] Furthermore, the temporary discharge power assembly includes a cylinder slide, a movable support is provided on the cylinder slide, a push plate is provided on the movable support, and the push plate is connected to the flipping mechanism.

[0012] Furthermore, the flipping mechanism includes a flipping block, which is connected to the movable support via a rotating shaft and is provided with a torsion spring. One end of the rotating shaft is provided with a flipping plate, and the movable support corresponding to the flipping plate is also provided with a flipping thrust cylinder. The push plate is fixed on the flipping block.

[0013] Furthermore, one end of the push plate is bent and equipped with a push finger.

[0014] Furthermore, the movable support is also connected by a slide rail, which is arranged parallel to the cylinder slide.

[0015] Furthermore, the material clamping and moving assembly includes a lower clamping piece and an upper clamping piece, which are respectively disposed on the side of the corresponding limiting groove for clamping on both sides of the substrate.

[0016] Furthermore, the unpowered guide rail includes a lower base and an upper cover plate, which cooperate to form a limiting groove.

[0017] The beneficial effects of this utility model are:

[0018] 1. By setting up a temporary feeding power component, the substrate can be transported to a fixed feeding position. The material clamping moving component clamps the substrate in a fixed position, ensuring accurate gripping. At the same time, it effectively solves the problem of the clamping blind zone of the material clamping moving component.

[0019] 2. The temporary unloading power assembly transfers the substrate in a fixed position to the next process without the need for a material clamping and moving assembly to assist in the transfer, thereby improving coordination efficiency and reducing waiting time.

[0020] 3. The lower drive wheel and the upper driven wheel work together to clamp and transport the substrate. When the substrate is detached from the lower drive wheel and the upper driven wheel, it moves without power, thus enabling effective positioning. At the same time, the swing mechanism effectively improves the adaptability of substrates of different thicknesses and sizes. Attached Figure Description

[0027] 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.

[0028] Reference Figures 1 to 5 As shown, one embodiment of the track conveying device of this utility model applied in a SIP mounting machine includes two parallel unpowered guide tracks 1. Limiting grooves 2 are formed on the corresponding surfaces of the two unpowered guide tracks. A material clamping and moving component 3 is provided on one side of one of the unpowered guide tracks, and a temporary feeding power component 4 and a temporary discharging power component 5 are respectively provided at both ends of the other unpowered guide track. (Refer to...) Figure 6 As shown, the material clamping and moving assembly includes a lower clamping piece 27 and an upper clamping piece 28. The lower clamping piece and the upper clamping piece are respectively disposed on the side of the corresponding limiting groove and are arranged vertically. The substrate 6 is located between the lower clamping piece and the upper and lower clamping pieces. The substrate is clamped by the relative movement of the lower clamping piece and the upper clamping piece, and then the material clamping and moving assembly moves, thus moving the substrate along the guiding direction of the non-powered guide track. The non-powered guide track includes a lower base 29 and an upper cover plate 30. The lower base and the upper cover plate cooperate to form a limiting groove. The limiting groove is laterally open. The limiting grooves on the two non-powered guide tracks are arranged opposite each other to limit the substrate from both sides, that is, the substrate can only move along the length direction.

[0029] In operation, the substrate is temporarily stored at the beginning of the unpowered guide rail after being fed in by the previous process. When processing is required on the substrate temporarily stored at the baffle, the temporary feeding power assembly transports the substrate from the beginning position to a fixed feeding position. Then, the material clamping and moving assembly clamps the substrate at the fixed position and moves it to the bonding position (where the chip is soldered onto the substrate). After bonding is completed, the material clamping and moving assembly clamps and moves the bonded substrate to the end of the unpowered guide rail for temporary storage. When the next process can receive materials, the temporary discharge power assembly transfers the substrate from the fixed position (the end temporary storage position) to the next process. In summary, the processing of one substrate is completed. Since the unpowered guide rail needs to be supported and fixed, the temporary feeding power assembly and the temporary discharge power assembly work together to transport the substrate.

[0030] Reference Figure 2 and Figure 3 As shown, the aforementioned temporary feeding power assembly includes a lower driving wheel 7 and an upper driven wheel 8. A clearance portion 9 is provided on the unpowered guide rail between the lower driving wheel and the upper driven wheel. The lower driving wheel is connected to and fixedly mounted to a drive motor 10, while the upper driven wheel is mounted on a swing mechanism 11. The lower driving wheel is fixed in position and is driven to rotate by the drive motor, while the upper driven wheel moves towards or away from the lower driving wheel through the swing mechanism. When moving away, the distance between the upper driven wheel and the lower driving wheel increases, allowing the substrate to move smoothly above the lower driving wheel and fit against it. When moving towards the lower driving wheel, the upper driven wheel presses the substrate against the lower driving wheel, and then the drive motor drives the lower driving wheel to rotate. Through this pressing fit, the substrate is horizontally transported.

[0031] Based on the above structure, the swing mechanism of this application is designed to include a mounting frame 12 and a swing arm 13. One end of the swing arm is shaft-connected to the mounting frame, and the other end is connected to the upper driven wheel and is equipped with a lower pressure plate 15. The middle part of the swing arm is connected to the mounting frame via a tension spring 16. A lower pressure cylinder 17 is also provided on the mounting frame. The telescopic rod of the lower pressure cylinder abuts against the lower pressure plate. The lower pressure cylinder is used to push the upper driven wheel to move towards the lower driving wheel, and the tension spring is used to move the upper driven wheel away from the lower driving wheel. The tension spring always maintains tension, pulling the upper driven wheel away from the lower driving wheel. When it is necessary to press the substrate to move, the lower pressure cylinder extends and presses against the lower pressure plate to move downward. The downward force is greater than the tension of the tension spring, so the tension spring is pulled open and stores energy. The movement of the lower pressure plate will drive the swing arm to swing downward, while simultaneously moving the upper driven wheel towards the lower driving wheel until the substrate is pressed against the lower driving wheel. This method does not need to consider the thickness of the substrate and has a wide range of applications. When there is no need to transport the substrate, the lower cylinder resets, the lower plate exerts no force, and the stretched spring also resets, that is, the upper driven wheel resets and moves away from the lower driving wheel.

[0032] Reference Figure 4 and Figure 5 As shown, the aforementioned temporary discharge power assembly is designed to include a cylinder slide 18, a movable support 19 on the cylinder slide, and a push plate 20 on the movable support. The push plate is connected to the flipping mechanism. Since the substrate needs to move, the temporary discharge power assembly needs to avoid interference during the movement. Therefore, the flipping mechanism needs to drive the push plate away from the substrate movement path. When discharge is required, the flipping mechanism drives the push plate into the substrate movement path, and then the cylinder slide moves, driving the push plate to push the substrate to move.

[0033] Based on the aforementioned material ejection method, this application designs a flipping mechanism, including a flipping block 21. The flipping block is connected to the movable support via a rotating shaft 22 and is equipped with a torsion spring. A flipping plate 23 is provided at one end of the rotating shaft, and a flipping thrust cylinder 24 is also provided on the movable support corresponding to the flipping plate. The push plate is fixed on the flipping block. The torsion spring can always apply a force to the flipping plate in one rotation direction, which is to drive the push plate away from the movement path. The flipping thrust cylinder extends by action and moves against the flipping plate. One end of the flipping plate is fixedly connected to the rotating shaft, so it will rotate against the flipping plate, that is, the rotating shaft rotates. At the same time, the flipping block rotates, that is, the push plate moves into the movement path of the substrate. When it is necessary to reset, the flipping thrust cylinder retracts, the force on the flipping plate disappears, the torsion spring also resets at the same time, driving the flipping block to rotate, that is, rotating the push plate out of the substrate movement path.

[0034] The aforementioned push plate has a push finger 25 bent at one end, which is simple in structure and can meet the pushing requirements of the base plate. The movable support is also connected by a slide rail 26, which is arranged parallel to the cylinder slide table, making the movement more stable.

[0035] 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.
