Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example

[0027] Reference Figure 1-5 A device for pressing and positioning circuit boards includes a pressing machine body 1, a placement plate 2, and a knob 3. The pressing machine body 1 includes a base, an inner operating chamber, a pressure plate, and a hydraulic system. The bottom of the pressing machine body 1 is the base, and a rectangular groove is provided inside the base corresponding to the positioning rod storage cylinder 7 to facilitate the movement of the positioning rod storage cylinder 7 inside the base. The upper end of the base is the inner operating chamber, and the placement plate 2 is placed at the bottom of the inner operating chamber. A pressure plate is provided at the upper end of the inner operating chamber, and a drive shaft is fitted and connected to the upper end of the pressure plate. The upper end of the drive shaft is connected to the hydraulic system, and the hydraulic system is installed inside the upper end of the pressing machine body 1.

[0028] A placement plate 2 is fitted inside the main body 1 of the pressing machine, and knobs 3 are fitted on both the left and right sides of the main body 1. A sealing plate 5 is fixedly installed on the upper surface of the placement plate 2, and a positioning sleeve 6 is fixedly installed inside the sealing plate 5. A positioning rod 4 is fitted inside the positioning sleeve 6, and a slider 9 is fitted at the bottom of the positioning rod 4. A positioning rod storage cylinder 7 is fixedly installed at the bottom of the slider 9, and a lead screw 8 is fitted inside the slider 9. One end of the lead screw 8 is fitted with a rotating shaft 10, and the other end of the rotating shaft 10 is fitted with the placement plate 2. This allows for adjustments to batches of different specifications. When the circuit board is being pressed, the operator can rotate the lead screw 8 by rotating the knobs 3 on both sides of the pressing machine body 1, which in turn moves the slider 9 on the surface of the lead screw 8. During this process, the operator can control the movement direction of the slider 9 by adjusting the rotation direction of the knobs 3. During the movement of the slider 9, the positioning rods 4 at the upper and lower ends of the slider 9 and the positioning rod storage cylinder 7 can move. Then, the operator can adjust the position of the positioning rods 4 on the surface of the placement plate 2 by rotating the knobs 3, thereby adjusting the spacing between the positioning rods 4 on the surface of the placement plate 2 to be consistent with the specifications of the circuit board.

[0029] A spring 11 is fixedly installed inside the positioning rod storage cylinder 7, and the upper end of the spring 11 is fixedly connected to the positioning rod 4. A second positioning sleeve 12 is fixedly installed inside the slider 9, and a positioning sleeve shaft 13 is fitted inside the second positioning sleeve 12. With this design, when the pressure plate presses down to press the circuit board, after the top of the positioning rod 4 contacts the pressure plate, the positioning rod 4 can move downward into the interior of the positioning rod storage cylinder 7. When the pressing is finished and the pressure plate rises, the positioning rod 4 can extend upward under the action of the spring 11 inside the positioning rod storage cylinder 7. When the positioning rod 4 moves up and down, the positioning sleeve shaft 13 inside the positioning sleeve 6 and the second positioning sleeve 12 can rotate along with the movement of the positioning rod 4. This allows the positioning sleeve 6 and the second positioning sleeve 12 to assist in positioning the positioning rod 4 in the normal state and prevent the positioning rod 4 from tilting. At the same time, through the positioning sleeve shaft 13, the positioning rod 4 can also be positioned during the retraction and extension process to prevent the positioning rod 4 from tilting.

[0030] The placement plate 2 has a cavity for mounting the lead screw 8, and the center of the placement plate 2 is a solid plate. The rotating shaft 10 is fitted into the left and right ends of the solid plate inside the placement plate 2. Through this design, the circuit board needs to be placed on the upper end of the solid plate on the upper surface of the placement plate 2 during the pressing process, so that the solid plate can stably provide support from the bottom during the pressing process.

[0031] The upper surface of the placement plate 2 is provided with a rectangular groove, and the sealing plate 5 is located inside the rectangular groove. The sealing plate 5 is divided into two parts. One end of each part of the sealing plate 5 is fixedly connected to the inner wall of the rectangular groove on the upper surface of the placement plate 2, and the other end of each part of the sealing plate 5 is fixedly connected to the positioning sleeve 6. Through this design, the positioning rod 4 can be adjusted and moved normally inside the rectangular groove. At the same time, the sealing plate 5 can prevent impurities from falling into the interior of the placement plate 2 through the rectangular groove and affecting the lead screw 8.

[0032] It should be noted that the sealing plate 5 is an accordion-style sealing sleeve. This design allows the sealing plate 5 on one side to retract as the positioning rod 4 and the positioning sleeve 6 move, while the sealing plate 5 on the other side can extend as the positioning sleeve 6 moves.

[0033] The slider 9 is a rounded rectangle, and a threaded hole is provided on one side of the rounded corner of the slider 9 to engage with the lead screw 8. The threaded hole acts as a nut to connect with the lead screw 8. When the lead screw 8 rotates, the slider 9 moves along the thread on the surface of the lead screw 8, thereby achieving linear motion.

[0034] Both ends of the lead screw 8 are fixedly equipped with connecting shafts, and the connecting shaft on one side of the lead screw 8 is connected to the rotating shaft 10. The connecting shaft on the other side of the lead screw 8 passes through the placement plate 2 and the main body 1 of the press and is fitted with the knob 3. During the rotation of the lead screw 8, the rotating shaft 10 can rotate with the lead screw 8. At the same time, the rotating shaft 10 can also connect the lead screw 8 and the placement plate 2. Through this design, when the operator rotates the knob 3, the lead screw 8 can rotate synchronously with the rotation frequency and direction of the knob 3.

[0035] Working Principle: When pressing circuit boards of different specifications and batches, the operator rotates the screw 8 by turning the knobs 3 on both sides of the pressing machine body 1, thereby moving the slider 9 on the surface of the screw 8. The direction of movement of the slider 9 is controlled by adjusting the rotation direction of the knobs 3. During the movement, the slider 9 drives the positioning rods 4 at its upper and lower ends and the positioning rod storage cylinder 7 to move. The operator adjusts the position of the positioning rods 4 on the surface of the placement plate 2 by rotating the knobs 3, adjusting the spacing between the positioning rods 4 on the surface of the placement plate 2 to be consistent with the specifications of the circuit board. When the pressure plate presses down to press the circuit board, after the top of the positioning rod 4 contacts the pressure plate, the positioning rod 4 moves downward and enters the interior of the positioning rod storage cylinder 7. When the pressing is completed and the pressure plate rises, the positioning rod 4 extends upward under the action of the spring 11 inside the positioning rod storage cylinder 7. When the positioning rod 4 moves up and down, the positioning sleeve 6 and the positioning sleeve shaft 13 inside the second positioning sleeve 12 rotate along with the movement of the positioning rod 4, so that the positioning sleeve 6 and the second positioning sleeve 12 can assist the positioning rod 4 in positioning under normal conditions to prevent the positioning rod 4 from tilting. At the same time, through the positioning sleeve shaft 13, the positioning rod 4 can also be positioned during the retraction and extension process to prevent the positioning rod 4 from tilting.

[0036] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.

[0037] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
