Detailed Description
As shown in fig. 1 to 4, the novel lead frame transfer device 100 includes a bracket 110 and a baffle 130. The bracket 110 is provided with a groove 111. The baffle 130 is used to adjust the width of the groove 111 so that the lead frame 200 can be smoothly not skewed while traveling within the groove 111.
A conveying device is arranged in the groove 111. In the example shown in the figures, the conveying means comprise a plurality of rollers 113. A roller 113 is rotatably disposed within the recess 111. The plurality of rollers 113 are arranged at intervals. The bracket 110 is provided with a motor 114. The motor 114 drives the drum 113 to rotate through the timing belt 115. The drum 113 may transfer the lead frame 200 when rotated.
The bracket 110 has a blocking device 116 mounted thereon. The blocking means 116 comprises a cylinder 117 and a blocking block 118. The cylinder 117 drives the blocking piece 118 to move. The blocking piece 118 is driven by the cylinder 117 to either block the movement of the lead frame 200 on the moving route to the female lead frame 200 or to move away from the moving route of the lead frame 200 to allow the lead frame 200 to continue to be transferred.
The utility model also comprises control means (not shown in the figures). The control device controls the operation of the cylinder 117 and the motor 114. The bracket 110 is provided with a sensor 119. The sensor 119 is configured to detect whether the lead frame 200 is present at a specified location, and to send a signal to the control device when the lead frame 200 is detected at the specified location. When the control device determines that the lead frame 200 is at the specified position according to the signal of the sensor 115, the control device controls the cylinder 117 to operate to move the blocking piece 118 to the transmission line of the lead frame 200, thereby preventing the lead frame 200 from being continuously transmitted to the specified position, and simultaneously controls the motor 114 to stop operating. When it is determined that the lead frame 200 is not at the specified position based on the signal from the sensor 119, the control device controls the air cylinder 117 to move the stopper 118 away from the transmission line of the lead frame 200, and starts the motor 114, so that the lead frame 200 can be continuously transmitted to the specified position.
A baffle 130 is disposed within the recess 111 and is adjustably positioned. The width of the groove 111 can be adjusted when the position of the baffle 130 is adjusted. The width of the groove 111 is adjusted to the size of the lead frame 200, so that the lead frame 200 is stable during transmission. In one example as shown, the baffle 111 is adjustably positioned perpendicular to the feed direction of the lead frame 200. According to the scheme of the utility model, the device further comprises a transmission mechanism 140, wherein the transmission mechanism 140 is connected with the baffle 130, and the baffle 130 is driven to move through the transmission mechanism 140. The transmission mechanism 140 comprises a screw 141 and a nut 142; the nut 142 is in threaded engagement with the screw 141; the screw 141 is rotatably disposed on the bracket 110, and the nut 142 is connected to the baffle 130. The support 110 is further provided with a guide rod 143, and the baffle 130 is sleeved on the guide rod 143 and can slide along the guide rod 143. The support 110 is provided with a scale 144, and the scale 144 is disposed along the moving direction of the baffle 130. A locking bolt 145 is provided on the baffle 130, and the locking bolt 145 is in threaded engagement with the baffle 130 and can protrude from the baffle 130 after screwing. The baffle 130 is provided with a notch 131; the baffle 130 is movably disposed along the axial direction of the drum 113, and the drum 113 passes through the baffle 130 from the notch 131 during the movement of the baffle 130.
As shown in fig. 5 and 6, a support plate 160 is provided at one side of the bracket 110. The support plate 160 is provided to be reversible. The rotary motor 161 is connected to a rotary shaft 162. The support plate 160 is connected to a rotation shaft 162. The rotating motor 161 drives the rotating shaft 162 to rotate, and the rotating shaft 162 drives the supporting plate 160 to turn over. According to the actual use requirement, the supporting plate 160 can be turned over by 90 degrees or more, so that the lead frame placed on the supporting plate 160 falls onto the roller 113 in the groove 111 of the bracket 110 after being turned over. As shown in fig. 6, when the shaft 152 rotates to drive the supporting plate 160 to rotate 90 degrees clockwise, the lead frame placed on the supporting plate 160 tilts rightward, and falls into the right groove 111 after being flipped.
The novel lead frame transmission device can be suitable for the transmission of lead frames with different sizes by adjusting the width of the grooves through the baffle plates, is convenient and flexible to use, and saves investment and production cost. The position of the baffle plate is adjusted by utilizing the matched transmission of the screw rod and the nut, and the operation is convenient and flexible.
