Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of three-dimensional solder paste detection equipment, and specifically provides an automatic feeding tooling based on a three-dimensional solder paste inspection machine. Background Art
[0002] In the electronic manufacturing industry, the production quality of circuit boards is of crucial importance, especially in the key step of printing solder paste. There are indeed some challenges in the solder paste printing process, including the control of the amount of solder paste and the assurance of printing quality. The accurate measurement of the amount of solder paste is directly related to the quality of solder joints and the reliability of circuit boards. To solve these problems, a solder paste thickness detector has been developed, which is a device that uses optical principles for measurement and can accurately calculate the height of the solder paste printed on the PCB board through triangulation technology.
[0003] The design of the solder paste thickness detector takes into account different measurement requirements and provides two modes: 2D measurement and 3D measurement. The 3D measurement technology ensures the accuracy of measurement data through automatic computer focusing. In practical applications, samples are transported to the interior of the detection device through a conveyor belt for solder paste thickness detection. However, the solder paste thickness may vary in different areas of the circuit board, which requires the detection device to be able to adapt to conveyor belts of different heights to achieve accurate measurement of the solder paste thickness.
[0004] Despite the significant technological progress made by modern detection devices, there are still some limitations in sample collection. For example, if the conveyor belt is set at a higher level, although it helps to accurately measure the solder paste thickness, it may be difficult to collect the solder paste sample after detection. On the contrary, if the conveyor belt is set at a lower level, although it is convenient for sample collection, it may affect the detection accuracy. In addition, if the circuit board is far from the detection device, it may lead to inaccurate measurement data because the distance change during transmission may affect the solder paste thickness.
[0005] In view of the above problems, there is an urgent need for an innovative design based on the original automatic feeding. Summary of the Utility Model
[0006] The technical solution of the utility model provides a solution significantly different from the prior art for the technical problem that the prior art solution is too single, so as to solve the problems raised in the above background art.
[0007] To achieve the above object, the utility model provides the following technical solutions: an automatic feeding tooling based on a three-dimensional solder paste inspection machine, including a conveying mechanism. A plurality of bottom plates are equidistantly installed on the conveyor belt of the conveying mechanism, and a set of height adjustment structures are provided on both sides of the top of each bottom plate. And a bearing plate is connected to the upper end of each set of height adjustment structures. A frame is installed on the top of each bearing plate, and guiding structures are provided on both sides of each frame. A detection device is installed in the middle area on the conveying mechanism.
[0008] Preferably, the height adjustment structure includes a toothed block drum, a chain, a fixed column, a first splicing toothed plate, a second splicing toothed plate, and an auxiliary telescopic rod. A toothed block drum is rotatably connected to both sides of each bottom plate, and a chain is connected between the toothed block drums through a sprocket. A fixed column is threadedly connected to each toothed block drum, and the upper end of each fixed column is connected to the corresponding bearing plate. A first splicing toothed plate and a second splicing toothed plate are respectively installed on the conveying mechanism. An auxiliary telescopic rod is connected between the top of each bottom plate and the bottom of the bearing plate.
[0009] Preferably, the first splicing toothed plate and the second splicing toothed plate are distributed in a staggered manner on both sides of the detection device, and both the first splicing toothed plate and the second splicing toothed plate are composed of a plurality of toothed block plates spliced together, and both the first splicing toothed plate and the second splicing toothed plate are meshed with the toothed block drum.
[0010] Preferably, the frame is set in a "return" type structure.
[0011] Preferably, the guiding structure includes a movable cylinder, an adjusting rod, a fitting ball, and a trigger block. A movable cylinder penetrates through both sides of each frame, and an adjusting rod is threadedly connected to each movable cylinder. A rubber fitting ball is connected to the inner end of each adjusting rod in the frame. Trigger blocks are provided on both sides of the top of the conveying mechanism near the detection device.
[0012] Preferably, the movable cylinder is set in a "worker" type structure, and the outer end of the movable cylinder located outside the frame is set in a hemispherical structure, and the movable cylinder and the frame are in a snap-fit sliding connection.
[0013] Compared with the prior art, the beneficial effect of the utility model is: for this automatic feeding tooling based on a three-dimensional solder paste inspection machine, during the process of conveying the circuit board to the detection device, through the provided height adjustment structure. When the circuit board passes through the preset first splicing toothed plate area, it will engage and trigger the height adjustment structure, pushing the bearing plate and the circuit board on it to slowly rise, making the circuit board closer to the detection device, thereby improving the detection accuracy. After the detection work is completed, the device will trigger the height adjustment structure to reset again in the second splicing toothed plate area, restoring the height of the bearing plate and the circuit board to the original state, facilitating subsequent collection and processing.
[0014] For the precise control of height adjustment, the number of plates on the first splicing tooth plate and the second splicing tooth plate is adjusted to change the number of meshing circles of the tooth block cylinder. This design can flexibly adjust the pushing height of the bearing plate according to different detection requirements to ensure the best detection effect. Brief Description of the Drawings

A fixed column 303 is threadedly connected to each toothed block rotating cylinder 301, and the upper end of each fixed column 303 is connected to the corresponding bearing plate 4. A first splicing toothed plate 304 and a second splicing toothed plate 305 are respectively installed on the conveying mechanism 1.

[0024] The first splicing toothed plate 304 and the second splicing toothed plate 305 are staggeredly distributed on both sides of the inspection device 7, and both the first splicing toothed plate 304 and the second splicing toothed plate 305 are composed of a plurality of toothed block plates spliced together, and both the first splicing toothed plate 304 and the second splicing toothed plate 305 are in meshing connection with the toothed block rotating cylinder 301.
