Description

Technical Field

[0001] The utility model belongs to the technical field of ejector fixtures, and particularly relates to an ejector fixture for a GKG printing machine that can quickly replace ejector fixtures. Background Art

[0002] In the surface sealing process of printed circuit boards, GKG printers (also known as solder paste printers) are used to print solder paste onto electronic products (such as circuit boards). With the popularity of integrated circuits, some PCB boards need to have electronic components installed on both sides, which means that the PCB boards need to be printed on both sides. When the PCB boards are printed on both sides, the printing operation is usually performed on the front side of the PCB boards and the electronic components are soldered before the printing operation on the back side of the PCB boards. When the soldered electronic components are placed on the ejector fixture, the PCB board is easily lifted up due to the limit of the ejector fixture, causing the PCB board to tilt and affect the printing accuracy of the PCB board, and even tilting and damaging the electronic components on the PCB board. In addition, because the existing ejector fixtures have no fool-proof design, it takes a long time for the staff to place and position them, affecting production efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a GKG printing machine quick replacement ejector fixture to solve the problems mentioned in the above background technology.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A GKG printing machine quick-change ejector fixture comprises: a bottom plate, a side plate, a top plate, and a marking mechanism; the bottom plate is a horizontal square metal plate, two groups of vertical side plates are vertically fixed on the bottom plate, the two groups of side plates are parallel to each other, and a plate-shaped top plate is vertically fixed on the top, the top plate is provided with customized reserved holes and grooves for avoiding electronic components on a PCB, two groups of rod-shaped anti-stupid pin rods are fixed at the bottom of the bottom plate, the planes where the axis lines of the two groups of anti-stupid pin rods are located are parallel to the sides of the bottom plate, the distances between the axis lines of the two groups of anti-stupid pin rods and the nearest front and rear sides of the bottom plate are LA and LB respectively, wherein LA≠LB, and a marking mechanism for marking identity information is provided in the middle of one group of side plates.

[0006] Furthermore, in order to prevent the anti-stupid pin rod from being dislodged from the base plate when the anti-stupid pin rod is positioned, multiple groups of magnets are embedded in the bottom of the base plate.

[0007] Furthermore, in order to record the detailed information of the PCB board adapted by the utility model, the marking mechanism includes: an embedded groove, a sign, a QR code, and an identity identification code; an inwardly concave groove is provided in the middle of the side plate to form an embedded groove, and a sign is provided in the embedded groove, on which a QR code is printed; an intaglio identity identification code is provided on the upper part of the embedded groove.

[0008] Furthermore, in order to facilitate the updating and revision of the sign, the marking mechanism also includes: a fixing bolt; the sign is fixed in the embedded groove in a detachable manner by the fixing bolt.

[0009] Furthermore, in order to facilitate the overall transfer and installation of the device, the width of the bottom plate is greater than the width of the side plates and the top plate, so that the bottom plate forms a vacant space on both sides of the side plates, and a lifting mechanism is installed in each group.

[0010] Furthermore, in order to facilitate the handheld transfer of the entire device, the lifting mechanism includes: a rotating seat, a swivel, and a hand-held part; the rotating seat is fixed on the bottom plate at the side empty position, and a swivel is rotatably fitted on the rotating seat, and the side of the swivel away from the rotating seat is set as a straight hand-held part.

[0011] Furthermore, in order to enable the lifting mechanism to be used in conjunction with a crane, a lifting ring is provided on the handheld portion of the lifting mechanism, and the handheld portion and the lifting ring are covered with an anti-slip rubber layer.

[0012] Furthermore, in order to adapt to electronic components of different heights on the PCB board, the reserved hole groove body is a non-through reserved groove adapted to the electronic components on the PCB board. To adapt to extra-long electronic components, part of the reserved groove is penetrated to form a reserved hole.

[0013] In summary, the utility model has the following beneficial effects:

[0014] ① No damage to electronic components: Through the establishment of reserved holes and grooves, the GKG printer places the PCB board to be printed on the top plate. Each group of electronic components is located in the corresponding reserved grooves, and some electronic components that are too high are located in the corresponding reserved holes, which will not cause the electronic components to be tilted or damaged.

[0015] ② With foolproof design, easy installation and positioning: through the establishment of foolproof pin rods and magnets, the utility model is moved as a whole so that the foolproof pin rods under the bottom plate are inserted into the foolproof holes on the base plate. Because the distances between the axis lines of the two sets of foolproof pin rods and the nearest front and rear sides of the base plate are LA and LB respectively, and LA≠LB, the base plate can only be embedded in the base plate in a single orientation, thereby completing the positioning and installation of the utility model. The magnets of the base plate can prevent the foolproof pin rods from escaping and shifting from the foolproof holes when positioning, and the positioning of the ejector fixture is simple and convenient

[0016] ③ The matching and searching is simple, fast and accurate: through the establishment of the marking mechanism, each set of ejector fixtures is adapted to the printing of a set of PCB boards, so a separate identification code is used to correspond to different PCB boards. The identification code is used to indicate the matching PCB board. The information scanned by the QR code records the detailed parameters of the PCB board adapted by each set of ejector fixtures. Through the establishment of the identification code and the QR code, it is convenient for the staff to quickly find the corresponding ejector fixture when a PCB board is produced, which reduces the time for replacing the ejector fixture and improves the accuracy of replacing the ejector fixture.
