Description

Technical Field

[0001] The utility model relates to the field of circuit board storage devices, in particular to a circuit board collector with high compatibility. Background Art

[0002] Circuit boards are widely used in various technical fields due to their assemblability and testability. The demand for circuit boards is particularly huge, so factories need to quickly mass-produce circuit boards. During the circuit board production process, after all processes are completed on a certain production line, a board collector is needed to neatly place the semi-finished or finished products of the circuit boards into the material frame for use in subsequent processes. However, the current board collector can only collect boards of a single width specification. When switching to circuit boards of different widths for production, the board collector must also be replaced with the corresponding specification, resulting in a longer time spent on switching production models on the production line. On the other hand, configuring too many board collectors will undoubtedly increase equipment costs. Therefore, it is necessary to produce a highly compatible board collector to solve the above problems. Utility Model Content

The storage mechanism 2 includes a first frame 21, a lifting drive device 22 and a first conveying platform 23. The lifting drive device 22 is fixed on the first frame 21. The first conveying platform 23 includes a mounting base 231, a rotary drive motor 232, a first conveyor belt 233, a second conveyor belt 234, a third conveyor belt 235, a synchronous rotating shaft 236, a lifting cylinder 237, a side stop bar 238 and a middle stop bar 239. The mounting base 231 is fixed At the power output end of the lifting drive device 22, the first conveyor belt 233, the second conveyor belt 234 and the third conveyor belt 235 are rotatably mounted on the mounting base 231 from left to right, and the synchronous rotating shaft 236 is rotatably mounted on the mounting base 231. The synchronous rotating shaft 236 is engaged with the first conveyor belt 233, the second conveyor belt 234 and the third conveyor belt 235 through gears. The rotary drive motor 232 is fixed on the mounting base 231, and the power output end of the rotary drive motor 232 is connected to the first conveyor belt 233, the second conveyor belt 234 and the third conveyor belt 235. One of the third conveyor belts 235 is driven and connected, the lifting cylinder 237 is fixed on the mounting base 231 with the power output end facing upward, the upper end surfaces of the first conveyor belt 233, the second conveyor belt 234 and the third conveyor belt 235 are all flush, the side bars 238 are fixed above the mounting base 231, and two groups of side bars 238 are provided, corresponding to the left side of the first conveyor belt 233 and the right side of the third conveyor belt 235 respectively. The upper end surface of the side bars 238 is higher than the upper end surface of the first conveyor belt 233, and the middle bar 239 is fixed on the lifting cylinder 2 37 is the power output end and corresponds to the second conveyor belt 234 and the third conveyor belt 235. The upper end surface of the middle block bar 239 is lower than the upper end surface of the first conveyor belt 233. The board feeding mechanism 1 is fixedly arranged at the rear end of the storage mechanism 2, and the board discharging mechanism 3 is fixedly arranged at the front end of the storage mechanism 2.

[0018] The circuit board is transported to the material frame on the storage mechanism 2 through the board feeding mechanism 1, and the material frame is placed on the first conveying platform 23. The first conveying platform 23 is compatible with two material frames of different widths. When the conveyed circuit board is of large width, a large material frame is used, and the bottom of the large material frame is placed on the first conveyor belt 233, the second conveyor belt 234 and the third conveyor belt 235. At this time, the lifting cylinder 237 is in a retracted state, the upper end of the middle stop bar does not contact the bottom of the material frame, and the side stop bars 238 limit the left and right sides of the material frame. The circuit board is first placed on the bottom layer in the material frame, and then, driven by the lifting drive device 22, the material frame descends layer by layer, and the board feeding mechanism 1 places the circuit boards in the material frame one by one.

On a conveying platform 23, the rotary drive motor 232 drives one of the first conveyor belt 233, the second conveyor belt 234 and the third conveyor belt 235 to rotate, thereby driving the other conveyor belts to rotate through the synchronous rotating shaft 236, so as to realize forward or backward conveying of the material frame. When the conveyed circuit board is of small width, a small material frame is used, and the bottom of the small material frame is placed on the first conveyor belt 233 and the second conveyor belt 234. At this time, the lifting cylinder 237 is in the ejection state, and the side stop bar 238 and the middle stop bar 239 on the left side limit the left and right sides of the material frame respectively, so that the first conveying platform 23 can be compatible with two material frames of different widths for use. The structures of the second conveying platform and the third conveying platform are the same as that of the first conveying platform 23. Similarly, the second conveying platform and the third conveying platform can also be suitable for material frames of two different widths. The advantage of this design is that it can be used for two different widths of material frames for the board collection process. When the circuit board model is switched, the material frame of the corresponding specification can be quickly switched for board collection, which reduces the switching time.

[0020] The position of the material frame is preliminarily limited by the limit frame 24 to prevent the material frame from being excessively deviated or tipped over.

[0021] The storage mechanism 2 also includes a first positioning device 25, which includes a fixed limit plate 251, a transverse cylinder 252 and a movable limit plate 253. The fixed limit plate 251 is fixed to the right side of the upper end of the left column 241, the transverse cylinder 252 is fixed to the lower side of the beam 243 and the power output end faces to the right, and the movable limit plate 253 is fixed to the power output end of the transverse cylinder 252 and corresponds to the right side of the second conveyor belt 234.

[0022] When the material frame is conveyed to the first conveying platform 23, the upper end of the material frame is positioned by the first positioning device 25, and the transverse cylinder 252 drives the movable limit plate 253 to move toward the side of the fixed limit plate 251, and the fixed limit plate 251 and the movable limit plate 253 clamp the top of the material frame.

[0023] The storage mechanism 2 also includes a second positioning device 26, which includes a first positioning cylinder 261, a second positioning cylinder 262, a first positioning block and a second positioning block. The first positioning cylinder 261 is fixed on the middle bar 239 and the power output end faces to the left. The first positioning block is fixed to the power output end of the first positioning cylinder 261 and corresponds to the right side of the second conveyor belt 234. The first positioning cylinder 261 and the first positioning block are each provided with two groups along the front-to-back direction. The second positioning cylinder 262 is fixed on the side bar 238 on the right side and the power output end faces to the left.

[0024] After the material frame is conveyed to the first conveying platform 23, the lower end of the material frame is clamped and positioned by the second positioning device 26. When a small width material frame is used, the first positioning cylinder 261 drives the first positioning block to be ejected, and the left side of the material frame is pushed to abut against the left column 241. When a large width material frame is used, the second positioning cylinder 262 drives the second positioning block to be ejected, and the material frame is pushed to abut against the left column 241.
