【Detailed ways】

The utility model relates to a positioning device with a vacuum suction effect, the main structure of which includes a vacuum pumping platform, at least one metal substrate arranged on the vacuum pumping platform, and at least one metal substrate arranged on the substrate or between the substrates. A bakelite component, at least one positioning hole is formed on each bakelite component, and the positioning hole provided on the bakelite component is used to combine with a circuit board for positioning with a locking piece.

Please refer to the first specific embodiment of the present utility model as shown in Figures 1 to 3, its main structure is a vacuum pumping platform (10), at least one substrate (20) that is located on the vacuum pumping platform, and is arranged on At least one bakelite block (30) on the base plate, each bakelite block (30) is respectively formed with at least one positioning hole (32).

The vacuum pumping platform (10) is generally an air pump that can generate a vacuum environment. The front end of the air pump is provided with a plurality of operation control devices, and a plurality of air chambers (not shown) are formed inside. Several through holes (12) are formed on the top surface to communicate with the air chambers. Each air chamber is connected to a vacuum suction slot (not shown in the figure), and is connected to a vacuum through a pipeline (not shown in the figure). A vacuum suction device (not shown in the figure) is connected to provide a power source for forming a vacuum state.

The base plate (20) can be divided into multiple pieces, and the screw lock element (22) can be respectively fixed on the top surface of the vacuum pumping platform (10), covering the through hole (12) on the top surface, and the base plate (20) Several air holes (24) are formed to pass through the entire substrate (20), and several accommodating holes (26) are formed on the top surface of the substrate (20), but do not pass through the substrate (20), each accommodating The hole (26) is used to accommodate a bakelite block (30), wherein the space between the accommodating hole (26) and the bakelite block (30) is tightly fitted and fixed.

Each bakelite block (30) is a bakelite component, and a positioning hole (32) is formed on its top surface, and a latch (34) is correspondingly inserted in the positioning hole (32), and a part of the latch (34) It protrudes beyond the positioning hole (32) and is used for tenon positioning with a corresponding through hole (52) on a circuit board (50).

Please refer to the second specific embodiment of the present utility model as shown in Figure 4 and 5, the vacuum pumping platform (10) in its main structure is the same as the first specific embodiment, so no more details, the difference of the present embodiment Because the Bakelite component is no longer configured on the base plate, it is no longer necessary to form the accommodation hole (26) on the base plate. Its structure is changed to: a rectangular bakelite strip (40) is placed in the middle of two rows of substrates (20), and two lock holes (42) are respectively formed on the two ends of the bakelite strip (40) for Let the screw lock element (44) pass through and fix the bakelite strip (40) on the top surface of the vacuum pumping platform (10). In addition, several positioning holes (46) are respectively formed on the bakelite strip (40) , the positioning holes (46) do not pass through the bakelite strip (40), each positioning hole (46) corresponds to a corresponding perforation (52) on a circuit board (50), and a screw lock element (48 ) through the locked position.

The key point of this utility model is: a bakelite element is provided on a base plate, because the bakelite element has the characteristic of being easy to arrange, it can still be kept flat after the hole is set, and the flat outer surface can keep the circuit board and the base plate close to each other. combine. After the bakelite components are processed and drilled, the pins are inserted, so that the circuit board and the pins on the bakelite components can be mortized together, so as to avoid the difficulty of drilling holes on the metal substrate and the uneven surface. The problem is that at the same time, the metal substrate can retain the original property of being easily attracted by vacuum. Therefore, the positioning device with vacuum suction effect of the utility model can achieve the characteristics of both positioning effect and vacuum suction effect, so as to increase the circuit Stability during board fabrication operations.
