The utility model will be further described with reference to a leadframe. When the lead frame is conveyed to a carrier of the printing equipment, the left support positioning column 2.1 positions the left side of the lead frame, the left support positioning column 2.1 is positioned at the outer side of the left side frame of the lead frame, the right support positioning column 3.1 positions the right side of the lead frame, the right support positioning column 3.1 is positioned at the outer side of the right side frame of the lead frame, and the position of the lead frame in the length direction is limited by the left support positioning column 2.1 and the right support positioning column 3.1 so as to facilitate the follow-up and down movement of the lead frame for printing. The mounting position of the right bracket 3 in the left-right direction can be adjusted through the right bracket waist-shaped adjusting hole 3.2, so that the distance between the left bracket positioning column 2.1 and the right bracket positioning column 3.1 can be matched with the length adjustment of the lead frame.
Specifically, the above-mentioned printing process is to perform laser printing on the lead frame, in the step of the laser printing process, the lead frame is provided and arranged on the printing platform, each lead frame has a plurality of unit products, and the unit products are orderly arranged on the lead frame. Preferably, the plurality of unit products are arranged in a matrix array. The lead frame is provided with positioning holes, when the printing platform moves relatively towards the pressing plate 1, for example, the platform moves upwards towards the direction of the pressing plate 1 through a motor or a cylinder, the positioning holes on the lead frame can be used for accommodating the pressing plate positioning columns 1.1, so that the pressing plate positioning columns 1.1 can be respectively inserted into the positioning holes, and the pressing plate positioning columns 1.1 can comprise more than two parts, so that positioning is performed to confirm whether the lead frame is offset leftwards, rightwards or rotationally.
The printing platform conveys the lead frame to a first height of a first position of a laser printing process (namely a position right below the printing positioning error-proofing device), and at the moment, the plane positions (on an X axis and a Y axis) of a plurality of unit products which are arranged in a matrix on the lead frame are all within a laser printing range of the laser printing process. When the first position is positioned correctly, the printing platform starts to rise through the motor or the cylinder, namely, moves longitudinally (namely, in the Z-axis direction), and lifts the lead frame to the second height together, so that the unit product of the lead frame is positioned in the laser printing range except the plane position, and the longitudinal position of the unit product is further positioned in the focal length range of laser printing, and the laser can effectively print default patterns (size, position, thickness and the like) on the product. And then in the process of ascending the lead frame in the process of adjusting the lead frame to the longitudinal focal length range of the laser, the lead frame moves in the longitudinal direction, so that the lead frame moves towards the direction of the printing positioning error-proofing device.
During the longitudinal movement of the lead frame, the first state of offset confirmation (left offset, right offset or rotation offset) is performed, and the printing platform is to convey the lead frame to the first height of the first position (namely, the position right below the printing position error proofing device) of the laser printing process, but the lead frame has abnormal left, right or rotation offset, so that the lead frame is conveyed to the first height of the second position (namely, the position not right below the printing position error proofing device). The printing platform starts to rise, namely longitudinally moves, longitudinally moves the lead frame towards the direction of the second height, contacts the left support positioning column 2.1 or the right support positioning column 3.1 when the lead frame does not reach the second height in the moving process, pushes the left support positioning column 2.1 or the right support positioning column 3.1 in the longitudinal direction, so that the printing positioning error-proofing device rises, is further far away from the detection sensor of the printing positioning error-proofing device, and enables the detection sensor signal to change, thereby detecting that the lead frame has abnormal leftward, rightward or rotary deviation and alarming reminding, and the operator further assists in resetting and removing.
Further, the second aspect of offset confirmation is performed while adjusting the leadframe height to be within the laser focal length range. On the right side of the lead frame, a region outside the range of the lead frame is a right virtual detection region, and during the process of lifting the printing platform to move the lead frame towards the second height direction, the right support positioning column 3.1 passes through the right virtual detection region outside the range of the lead frame, at this time, the bottom surface of the right support positioning column 3.1 is not contacted with the lead frame, and the side surface of the right support positioning column is contacted with the right side surface of the lead frame. In some alternative embodiments, the bottom surface of the right support post 3.1 is not in contact with the leadframe, and the right support post 3.1 is not in contact with the right side of the leadframe, with a space therebetween. In some alternative embodiments, the left support positioning post 2.1 is used to make the lead frame prop against the left support positioning post 2.1 when the first height is reached, and the left support positioning post 2.1 is maintained in the left virtual detection area outside the range of the lead frame when the printing platform is lifted to move the lead frame towards the second height, so as to ensure the position of the lead frame in the left range.
After the second pattern of offset confirmation is completed, the bottom surface of the left support positioning post 2.1 does not contact the lead frame, further, the bottom surface of the left support positioning post 2.1 is lower than the upper surface of the lead frame, and further, the bottom surface of the left support positioning post 2.1 is lower than the horizontal height of the lead frame. From the view of the left side of the lead frame, the left bracket post 2.1 overlaps the lead frame at the level of the lead frame, at which time it can be confirmed that the left position of the lead frame is not offset. At this time, the bottom surface of the right support post 3.1 does not contact the lead frame, further, the bottom surface of the right support post 3.1 is lower than the upper surface of the lead frame, and further, the bottom surface of the right support post 3.1 is lower than the horizontal height of the lead frame. From the perspective of the right side of the lead frame, the right bracket post 3.1 overlaps the lead frame at the level of the lead frame, at which point it can be confirmed that there is no shift in the right side position of the lead frame. In some alternative embodiments, the left side position of the leadframe is not offset and the right side position of the leadframe is not offset and is both confirmed and present.
Next, a process of detecting an abnormal shift by using the second pattern shift checking step when the lead frame is abnormally shifted will be described. And when the lead frame is abnormally shifted leftwards, carrying out second-state shift confirmation, providing a first sensor arranged adjacent to the left side of the lead frame, providing a second sensor arranged adjacent to the right side of the lead frame, wherein the printing platform is used for carrying the lead frame to a first height of a first position of a laser printing process, but the lead frame is abnormally shifted leftwards, so that the lead frame is carried to a first height of a second position, the printing platform starts to lift, namely longitudinally moves, longitudinally moves the lead frame towards the direction of the second height, the left support positioning column 2.1 is positioned on a longitudinal action path of the left side of the lead frame, is pushed by the longitudinal direction of the lead frame when the second height is not reached in the moving process, and enables the left side of the pressing plate 1 to be tilted further away from the first sensor, so that a signal of the first sensor is changed, and the abnormal leftwards shift of the lead frame is detected. In some alternative embodiments, since the left bracket positioning post 2.1 and the right bracket positioning post 3.1 are disposed on the same platen 1, the right side of the platen 1 will also tilt and further away from the second sensor. In time sequence, the time for tilting the left side of the pressing plate is earlier than the time for tilting the right side of the pressing plate, and the tilting degree of the left side of the pressing plate is greater than the tilting degree of the right side of the pressing plate in the tilting degree, so that when the signal of the first sensor changes and the signal of the second sensor does not change, the signal represents that the lead frame moves leftwards, or the signal of the first sensor changes earlier than the signal of the second sensor, the signal represents that the lead frame shifts leftwards.
Next, a process of detecting an abnormal offset by using the offset confirmation step of the second aspect when another abnormal offset pattern of the lead frame occurs will be described. In the case of an abnormal rightward shift of the leadframe, a second sensor is provided adjacent to the right side of the leadframe, and in some embodiments, the printing platform is to handle the leadframe to a first height at a first location of the laser printing process, but the leadframe is abnormally shifted rightward such that the leadframe is handled to a first height at a third location. The printing platform starts to rise, namely longitudinally moves, longitudinally moves the lead frame towards the direction of the second height, the right support positioning column 3.1 is located on the longitudinal action path on the right side of the lead frame, is pushed in the longitudinal direction of the lead frame when the right support positioning column does not reach the second height in the moving process, enables the right side of the pressing plate 1 to be tilted, is further far away from the second sensor, enables the second sensor signal to change, and detects abnormal rightward deviation of the lead frame. In some alternative embodiments, since the left bracket positioning post 2.1 and the right bracket positioning post 3.1 are disposed on the same platen 1, the left side of the platen 1 will also tilt away from the first sensor. In time sequence, the tilting time of the right side of the pressing plate is earlier than the tilting time of the left side of the pressing plate, and the tilting degree of the right side of the pressing plate is greater than the tilting degree of the left side of the pressing plate, so that when the second sensor signal changes and the first sensor signal does not change, the lead frame moves rightwards, or the second sensor signal changes earlier than the signal change of the first sensor, the lead frame shifts rightwards.
