Description

Technical Field

[0001] The utility model relates to the field of SMT patch pressing, in particular to a simple pressing device for SMT patch. Background Technique

[0002] SMT patch refers to the abbreviation of a series of process flows processed on the basis of PCB. PCB (Printed Circuit Board) is a printed circuit board. SMT is the abbreviation of Surface Mounted Technology (Surface Mounted Technology), which is the most popular technology and process in the electronic assembly industry.

[0003] Before and after the lamination of some products, pressing is required to achieve a more stable structure. The general pressing operation is to manually align the equipment and press down with a pressing plate. Often, the situation of incorrect pressing position and product scrapping is likely to occur, and this problem needs to be solved urgently. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a simple pressing device for SMT patch, which has a simple structure, accurate positioning, and the pressing die is fixed by being squeezed on both sides and will not deviate from the preset position, and the pressing effect is good.

[0005] To solve the above technical problem, the utility model provides a simple pressing device for SMT patch, including a base. A moving loading module and an extrusion module are arranged on the base. The moving loading module includes a bottom plate fixed on the base. A bottom rail is arranged on the bottom plate. A limiting seat and a side plate are respectively arranged on both sides of the bottom rail. A first moving seat is arranged on the bottom rail, and a bottom die is arranged on the first moving seat. A side rail is arranged on the side plate, a second moving seat is arranged on the side rail, an auxiliary plate is arranged on the second moving seat, a placing groove is arranged on the auxiliary plate, symmetric clamping plates are arranged in the placing groove, a through hole is arranged at the central position of the auxiliary plate, columns are arranged at the positions corresponding to each clamping plate on the auxiliary plate, and clamping springs are arranged between the columns and the clamping plates. The extrusion module includes a support column, an installation seat is arranged on the support column, a cylinder is arranged on the installation seat, a pressing plate is arranged at the output end of the cylinder, and a pressing die adapted to the through hole is arranged on the pressing plate.

[0006] Further, a push rod is arranged on the first moving seat, and anti-collision rods are arranged at the positions corresponding to the limiting seat and the side plate on both sides of the first moving seat.

[0007] Further, a first guiding shaft is arranged between the pressing plate and the second moving seat, and a buffer spring is sleeved on the periphery of the first guiding shaft.

[0008] Further, a second guiding shaft is provided on one side of the auxiliary plate, and the clamping plate is arranged on the second guiding shaft and can move along the second guiding shaft.

[0009] Further, clamping blocks are arranged in the placement groove between the clamping plates.

[0010] Further, an auxiliary pull rod is provided on one side of the mounting seat.

[0011] Further, a mounting groove is provided on the base, and the bottom plate is fixed in the mounting groove.

[0012] The beneficial effects of the present utility model: When the device is in use, the components to be pressed are directly placed on the bottom die. The bottom die is arranged on the first moving seat and different bottom dies can be replaced according to the sizes of products in different batches. After the placement is completed, the first moving seat is pushed towards the side plate by the push rod on one side until it can no longer be pushed. After the pushing is completed, the cylinder drives the pressing plate to press down, and the pressing plate drives the pressing die to press down to complete the pressing operation.

[0013] The positioning operation of the pressing die is as follows: First, the pressing die is placed in the through hole. According to the different required positioning pressing die pressures, the clamping plates on both sides are pulled out. There is a clamping spring between the clamping plate and the column. Therefore, the elastic potential energy of the clamping spring will drive the clamping plate to pull back. The clamping plate will drive the internal clamping blocks to squeeze, and the clamping blocks on both sides will clamp the middle pressing die, thus playing a temporary fixing effect on the pressing film and ensuring that it will not deviate from the position.

[0025] During use, the components to be pressed are placed directly on the bottom die 26, which is arranged on the first movable seat 25. Different bottom die 26 can be replaced according to the size of different batches of products. After placement, the first movable seat 25 is pushed toward the side plate 24 by the push rod 29 on one side until it can no longer be pushed. After pushing, the cylinder 6 drives the pressing plate 7 to press down, and the pressing plate 7 drives the pressing die 8 to press down to complete the pressing operation.

[0026] The positioning operation of the die 8 is as follows: first, the die 8 is placed in the through hole 33, and the clamping plates 32 on both sides are pulled out according to the different pressures required to position the die 8.
