Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, and in particular to a PCB board pressing and testing mechanism. Background Art

[0002] A PCB is a carrier for the electrical interconnection of electronic components. During the PCB manufacturing process, a laminating machine is used to press and shape the PCB. Since the uniformity of the pressure in the laminating machine has a significant impact on the lamination quality, it is necessary to inspect the mold points on the laminating machine during the PCB lamination process.

[0003] Chinese Patent Publication No. CN221445882U discloses a PCB board lamination and inspection mechanism, relating to the field of PCB board processing technology. The mechanism includes a first mounting plate, a Z-axis drive motor, and an X-axis drive motor. In this invention, when installing a vision system inspection component, the rotating frame is rotated to a horizontal position; when disassembling the vision system inspection component, the rotating frame is rotated to an inclined position. The installation mechanism is used to install and disassemble the vision system inspection component, improving the efficiency of installation and disassembly and facilitating its use. Through the cooperation of the Z-axis drive motor, the first moving mechanism, the X-axis drive motor, and the second moving mechanism, the vision system inspection component can be moved in the Z-axis and X-axis directions. During the movement, the module points on the equipment are photographed and scanned. By periodically activating the vision system inspection component to inspect the module points on the equipment, defects in the module points can be prevented from causing PCB board scrapping.

[0004] In the prior art, when fixing the mounting base of the detection component, it is mainly positioned by a fixing plate and a positioning plate, and then the mounting base is clamped by a pressure plate in conjunction with a third threaded rod. However, before the pressure plate fixes the mounting base, the mounting base is in a loose state and is easy to shift left and right along the fixing plate, making it difficult to fix the equipment at the central axis of the mounting plate. Therefore, blind spots are easy to occur during subsequent detection. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a PCB board pressing and testing mechanism to solve the technical problems mentioned in the background.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A PCB board lamination testing mechanism includes a base plate, a fixing clamp plate is fixedly installed on one side of the upper end of the base plate, and two sets of sliding grooves are opened at the upper end of the base plate. Guide blocks are provided inside the sliding grooves, and the tops of the two guide blocks are connected to the sliding clamp plate.

[0008] The base plate has guide rails on both sides of its upper end. Positioning plates are slidably installed inside both guide rails, and the bottom ends of the two positioning plates are connected to an extension plate. The top wall of the extension plate is in contact with the bottom wall of the base plate. A locking groove is provided at the bottom end of the extension plate. Extension clamps are provided on both sides of the locking groove. The end of the extension clamp away from the locking groove is bent and extends to the top side of the positioning plate. A synchronous adjustment device is provided at the bottom end of the extension plate.

[0009] Furthermore, the interiors of the two sliding grooves are respectively provided with an adjusting screw and a guide rod, and the guide block corresponding to the adjusting screw is threadedly engaged with the adjusting screw.

[0010] Furthermore, the synchronous adjustment device includes an arc-shaped plate, which is fixedly connected to the bottom surface of the extension plate. Rotating rings are provided on both sides of the arc-shaped plate. A bidirectional screw is provided inside the arc-shaped plate, and positioning discs are fixedly connected to both ends of the bidirectional screw. The positioning discs on both sides are respectively inserted into the interior of the two rotating rings.

[0011] Furthermore, the bidirectional screw includes a screw shaft, both ends of the outer surface of the screw shaft are fixedly provided with external threads, and the thread directions of the two sets of external threads are opposite.

[0012] Furthermore, the bottom end of the extension clamp is provided with a threaded groove, which is threadedly engaged with the bidirectional screw, and the threaded grooves on the bottom sides of the two extension clamps are arranged opposite to each other.

[0013] Furthermore, the end of the positioning disk away from the bidirectional screw is provided with a hexagonal groove.

[0014] In summary, this utility model has at least one of the following beneficial technical effects:

[0015] 1. The PCB board pressing and testing mechanism uses the rotation of a bidirectional screw to make two extension clamps move synchronously and simultaneously toward the central axis of the base plate. At this time, the part of the extension clamps extending to the top side of the positioning plate will clamp the two sides of the mounting seat, so that the mounting seat is located at the central axis of the top surface of the base plate, thereby positioning the left and right sides of the mounting seat and preventing the mounting seat from shifting to the left or right, so as to prevent the mounting seat from shifting after it is fixed.

[0016] 2. In this PCB board pressing and testing mechanism, since the positioning plate is slidably connected to the base plate via the guide rail, the positioning plate will move synchronously with the mounting base as the sliding clamp pushes the mounting base to move. This improves the stability during the locking process of the mounting base and avoids problems such as displacement of the mounting base during the locking process, thereby achieving the purpose of improving the stability of the mounting base during the fixing process.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0025] Reference Figures 1-5 The present invention discloses a PCB board pressing and testing mechanism, including a base plate 1, a fixing clamp 2 fixedly disposed on one side of the upper end of the base plate 1, two sets of sliding grooves 3 are opened at the upper end of the base plate 1, and guide blocks 4 are disposed inside the sliding grooves 3, and the top ends of the two guide blocks 4 are connected to the sliding clamp 5.

[0026] The upper end of the base plate 1 is provided with guide rails 6 on both sides. Positioning plates 7 are slidably arranged inside the two guide rails 6, and the bottom ends of the two positioning plates 7 are connected to an extension plate 8. The top wall of the extension plate 8 is in contact with the bottom wall of the base plate 1. The bottom end of the extension plate 8 is provided with a locking groove 9. The inside of the locking groove 9 is provided with extension clamping plates 10 on both sides. The end of the extension clamping plate 10 away from the locking groove 9 is bent and extends to the top side of the positioning plate 7. The bottom end of the extension plate 8 is provided with a synchronous adjustment device 11.

[0027] In this embodiment, when installing the mounting base of the detection component, the mounting base is placed on the upper part of the base plate 1 and positioned between the fixed clamping plate 2 and the sliding clamping plate 5. At this time, the synchronous adjustment device 11 controls the extension clamping plates 10 on both sides to move towards the central axis of the base plate 1 simultaneously. At this time, the part of the extension clamping plate 10 extending to the top side of the positioning plate 7 will clamp the two sides of the mounting base, so that the mounting base is positioned at the central axis of the top surface of the base plate 1, thereby positioning the left and right sides of the mounting base and preventing the mounting base from shifting to the left or right.

[0028] After the left and right sides of the mounting base are fixed, push the sliding clamp 5 to move so that the sliding clamp 5 is close to the side wall of the mounting base, and push the mounting base to move until the mounting base contacts the fixed clamp 2. At this time, the purpose of fixing the mounting base can be effectively achieved.

[0029] Since the positioning plate 7 is slidably connected to the base plate 1 via the guide rail 6, the positioning plate 7 will move synchronously with the mounting base as the sliding clamp 5 pushes the mounting base to move, so as to improve the stability during the locking process of the mounting base and avoid problems such as displacement of the mounting base during the locking process.

[0030] In a further preferred embodiment of this utility model, such as Figure 1-5 As shown, the two sliding grooves 3 are respectively provided with adjusting screws 12 and guide rods 13, and the guide block 4 corresponding to the adjusting screws 12 is threadedly engaged with the adjusting screws 12.

[0031] In this embodiment, by rotating the adjusting screw 12, the guide block 4, which is threadedly engaged with the adjusting screw 12, moves, thereby pushing the sliding clamp 5 to move.

[0032] In a further preferred embodiment of this utility model, such as Figure 1-5 As shown, the synchronous adjustment device 11 includes an arc plate 111, which is fixedly connected to the bottom surface of the extension plate 8. Rotating rings 112 are provided on both sides of the arc plate 111. A bidirectional screw 113 is provided inside the arc plate 111. Positioning disks 114 are fixedly connected to both ends of the bidirectional screw 113, and the positioning disks 114 on both sides are respectively inserted into the interior of the two rotating rings 112.

[0033] In this embodiment, by setting the arc plate 111, after the arc plate 111 and the extension plate 8 are fixed to each other, a cavity can be formed on the inner side of the arc plate 111, so that the bidirectional screw 113 can rotate on the inner side of the arc plate 111. The positioning plate 114 and the rotating ring 112 are used to rotatably connect the two ends of the bidirectional screw 113 to the two ends of the arc plate 111, thereby facilitating the rotation of the bidirectional screw 113 on the inner side of the arc plate 111.

[0034] In a further preferred embodiment of this utility model, such as Figure 1-5 As shown, the bidirectional screw 113 includes a screw shaft 1131, and both ends of the outer surface of the screw shaft 1131 are fixedly provided with external threads 1132, and the thread directions of the two sets of external threads 1132 are opposite.

[0035] In this embodiment, a bidirectional screw 113 is formed by the screw shaft 1131 and the external thread 1132. Since the thread directions of the two external threads 1132 are opposite, they can effectively push the extension clamps 10 on both sides to move in opposite directions during use, so as to apply pressure to the left and right sides of the mounting seat at the same time, so as to push the mounting seat to the central axis of the base plate 1.

[0036] In a further preferred embodiment of this utility model, such as Figure 1-5 As shown, the bottom end of the extension clamp 10 is provided with a threaded groove 14, which is threadedly engaged with the bidirectional screw 113, and the threaded grooves 14 on the bottom sides of the two extension clamps 10 are arranged opposite to each other.

[0037] In this embodiment, the threaded groove 14 is provided to cooperate with the external thread 1132 so that when the bidirectional screw 113 rotates, the extension clamp 10 can be moved by the external thread 1132 and the threaded groove 14. The threaded groove 14 is respectively engaged with the thread direction of the two sets of external threads 1132, thereby facilitating the rotation of the bidirectional screw 113 so that the two extension clamps 10 can move synchronously and simultaneously in two directions.

[0038] In a further preferred embodiment of this utility model, such as Figure 1-5 As shown, the end of the positioning disk 114 away from the bidirectional screw 113 is provided with a hexagonal groove 115.

[0039] In this embodiment, the hexagonal slot 115 is designed to facilitate the connection of the motor shaft or to allow the bidirectional screw 113 to be rotated manually using a hexagonal wrench, thereby facilitating the installation of the detection component mounting base.

[0040] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
