Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of semiconductor processing, and particularly to a semiconductor package frame clamping and transferring device. BACKGROUND

[0002] In the process of semiconductor devices, the lead frame is formed into a package frame after the core sticking, bonding and plastic encapsulation processes are completed. Then, the lead frame exposed outside the plastic encapsulation body needs to be surface treated, such as electroplating, to improve the conductivity and corrosion resistance of the pins. After that, the package frame is placed in a collection frame after being flipped 90 degrees by a clamp. However, in actual operation, the distance between two adjacent package frames is very small when they are hung on the conveying hanger, which is much smaller than the thickness of the collection frame.

DETAILED DESCRIPTION

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the drawings, but the embodiments described herein are only some of the embodiments of the present application, not all the embodiments.

[0030] As Figures 1-9 shown, the embodiments of the present application provide a semiconductor package frame clamping and transferring device, which comprises a workbench 100, a transfer mechanism 200 and a clamping mechanism 300.

[0031] The workbench 100 is provided with two through parts 101 along the length direction thereof, and each of the through parts 101 is provided with a collecting frame 102 moving in the vertical direction, for collecting the packaging frames placed in sequence. The transfer mechanism 200 includes two side plates 201 respectively located on both sides of the workbench 100 in the length direction and moving towards each other, and a chassis 202 located below the workbench 100, and the inner side of the side plate 201 is provided with a plurality of bearing rods 203 arranged at intervals along the length direction thereof and moving in the width direction of the workbench 100, and the bearing rod 203 is L-shaped and used for bearing the packaging frame. In use, the two sides of the packaging frame are located on the horizontal section of the bearing rod 203, and at this time the bearing rod 203 is located directly above the collecting frame 102, and the inner side of the vertical section of the bearing rod 203 is flush with the inner side of the collecting frame 102, and the bearing rods 203 are moved away from each other along the width direction of the workbench 100, so that the packaging frame falls into the collecting frame 102. The chassis 202 is provided with two U-shaped parts respectively aligned with one of the through parts 101, and the two sides of the U-shaped part are provided with a first limiting block 204 and a second limiting block 205 respectively located at both ends inside the through part 101 and adjustable in spacing, and the first limiting block 204 is located at one end of the through part 101 close to the center of the workbench 100, and the first limiting block 204 and the second limiting block 205 are both L-shaped and move synchronously with the side plate 201 on the same side, for limiting the collecting frame 102, so as to ensure that the packaging frame can fall smoothly into the collecting frame 102. The clamping mechanism 300 includes a rotating plate 301 provided above the workbench 100 and rotatingly arranged, and the rotating axis of the rotating plate 301 is parallel to the length direction of the workbench 100, and a moving plate 302 is provided below the rotating plate 301 and moves in the thickness direction thereof, and the two sides of the moving plate 302 are respectively provided with a plurality of positioning rods 303 arranged along the length direction thereof and L-shaped clamping blocks 304, and the spacing between the positioning rods 303 is adjustable to adapt to the positions of the holes on packaging frames of different sizes, and the upper end of the clamping block 304 is rotatably arranged, and the rotating axis thereof is parallel to the rotating axis of the rotating plate 301, for clamping the packaging frame.In the actual transferring process, the rotating plate 301 is rotated, the moving plate 302 is changed from the horizontal state to the vertical state, and is moved towards the conveying hanger, until the moving plate 302 abuts against the surface of the packaging frame, the positioning rod 303 is penetrated into the hole of the packaging frame, then the clamping block 304 is rotated, the short end of the clamping block 304 is parallel to the surface of the moving plate 302, the packaging frame is clamped, then the moving plate 302 is moved back, the packaging frame is taken off from the conveying hanger, then the rotating plate 301 is rotated back, the rotating plate 301 is changed from the vertical state to the horizontal state, thereby the state of the packaging frame is changed from the vertical state to the horizontal state, and the packaging frame is supported by the short end of the clamping block 304, then the moving plate 302 is moved downwards by a distance, then the clamping block 304 is rotated back, the short end of the clamping block 304 is perpendicular to the surface of the moving plate 302, so that the packaging frame can fall on the bearing rod 203 under the action of the gravity of the packaging frame, then the two packaging frames are away from each other and are located above the through portion 101, finally the bearing rod 203 is moved along the width direction of the workbench 100 to be away from each other, so that the packaging frame can fall into the collecting frame 102.

[0032] Specifically, as shown in Figures 2-4 , the adjacent two bearing rods 203 are further provided with limiting rods 208, the limiting rods 208 are installed on the side plates 201, when the bearing rod 203 is at the farthest end of the stroke, the inner wall of the limiting rod 208 is flush with the inner wall of the bearing rod 203, and the inner wall of the limiting rod 208 is always flush with the inner wall of the collecting frame 102, thereby providing limiting for the two sides of the packaging frame when the bearing rod 203 is moved, avoiding the packaging frame from following the movement under the action of the friction force, and the lower end of the bearing rod 203 is flush with the upper end of the collecting frame 102, ensuring that the packaging frame can smoothly fall into the collecting frame 102, avoiding that the packaging frame is clamped into the gap between the lower end of the limiting rod 208 and the upper end of the collecting frame 102.

[0033] Specifically, as shown in Figure 2 , Figure 5 , the bearing rods 203 located on the same side are all installed on the cross rods 206, the side surface of the cross rod 206 is connected to the moving end of the horizontal linear mechanism, and the side surface of the cross rod 206 is further provided with convex rods 207, the horizontal linear mechanism 226 is installed on the side plates 201, and the horizontal linear mechanism 226 is arranged along the width direction of the workbench 100, the convex rods 207 are penetrated into the side plates 201, after the packaging frame is placed on the bearing rod 203, the cross rod 206 is driven to move along the width direction of the workbench 100 by the horizontal linear mechanism 226, so that the bearing rod 203 moves towards the direction away from the center of the workbench 100, under the blockage of the limiting rods 208, the packaging frame will not move in the horizontal direction, after the short end of the bearing rod 203 is completely separated from the bottom surface of the packaging frame, the packaging frame can fall into the collecting frame 102 under the action of the gravity of the packaging frame.

[0034] Specifically, as shown in Figures 1-2 , Figure 7 , when the two packaging frames are placed on the bearing rod 203 at the same time, the distance between the two packaging frames is much smaller than the distance between the two collecting frames 102, so the packaging frames need to be pushed to move above the collecting frames 102. Therefore, the transfer mechanism 200 further comprises a push plate 220 located at the center of the workbench 100. The upper end section of the push plate 220 is in the shape of an isosceles triangle, so that when the push plate 220 moves upward, it can smoothly pass between the two packaging frames. The lower end of the push plate 220 is provided with a rotating shaft 221, which is rotatably installed on a lifting plate 222 and penetrates a rotating ring 223 that rotates around its own axis. The rotating shaft 221 and the rotating ring 223 are in key groove sliding fit, that is, a plurality of key grooves are arranged on the side wall of the rotating shaft 221 in the circumferential direction, and a plurality of key pins are arranged on the inner wall of the rotating ring 223 in the circumferential direction. The key pins are in sliding fit with the key grooves, so that the rotating shaft 221 and the rotating ring 223 can slide relative to each other while ensuring the transmission of power. The rotating ring 223 is rotatably installed on the workbench 100, and the rotation of the rotating ring 223 can be driven by a belt. One end of the lifting plate 222 is connected to the moving end of a vertical lifting mechanism installed on the workbench 100. After the two packaging frames are placed on the bearing rod 203, the lifting plate 222 is driven by the vertical lifting mechanism to move upward, and the push plate 220 is driven to move upward, so that the push plate 220 passes between the two packaging frames. Then the rotating ring 223 is driven to rotate, and the push plate 220 is driven to rotate, so that the two packaging frames are moved away from each other until both of them are located above the collecting frames 102. Then the push plate 220 is rotated back and reset downward.

[0035] More specifically, as shown in Figure 2 , Figure 7 , in order to ensure that the push plate 220 can smoothly pass between the two packaging frames during upward movement, the length direction of the push plate 220 needs to be parallel to the width direction of the packaging frame. Therefore, an arc-shaped ring 224 is arranged on one side of the lifting plate 222, and one end of the arc-shaped ring 224 is parallel to the width direction of the packaging frame. The bottom of the push plate 220 is provided with a sliding block 225, which is in sliding fit with the arc-shaped ring 224. When the sliding block 225 is located at one end of the arc-shaped ring 224, the length direction of the push plate 220 is parallel to the width direction of the packaging frame, so that the push plate 220 can smoothly pass between the two packaging frames.

[0036] Specifically, as shown in Figures 2-4As shown, in order to avoid the packaging frame from moving too far under the action of inertia during the process of being pushed, two baffle plates 209 are arranged between the side plates 201 at both ends thereof, and the inner wall of the baffle plate 209 is always flush with the inner wall of the collecting frame 102. The packaging frame is blocked by the baffle plate 209 to ensure that the packaging frame can smoothly fall into the collecting frame 102. The outer side of the baffle plate 209 is provided with a sliding plate 210, the length direction of the sliding plate 210 is parallel to the length direction of the workbench 100, and the side surface is provided with a sliding groove 211 arranged along the length direction. A supporting rod 212 is arranged in the sliding groove 211, the supporting rod 212 is installed on the workbench 100, and the both ends of the side plate 201 are sleeved on the supporting rod 212. Two limiting rings 213 are arranged on the middle part of the supporting rod 212, and the sliding plate 210 is fitted between the limiting rings 213 to avoid the baffle plate 209 from turning left and right. By moving the baffle plate 209, the supporting rod 212 and the sliding groove 211 are relatively slid to adjust the position of the baffle plate 209 to adapt to packaging frames of different sizes.

[0037] Specifically, as shown in Figures 2-4 , in order to ensure that the baffle plate 209 can move synchronously with the second limiting block 205 and the inner wall of the baffle plate 209 can be flush with the inner wall of the collecting frame 102, a supporting plate 214 is arranged on the outer side of the baffle plate 209, and the length direction of the supporting plate 214 is parallel to the width direction of the workbench 100. The both ends of the supporting plate 214 are provided with long holes 215 along the length direction, and a penetrating rod 216 is arranged in the long hole 215. The lower end of the penetrating rod 216 is connected to the second limiting block 205. When the second limiting block 205 moves, the baffle plate 209 is driven to move synchronously. In addition, the baffle plate 209 can also avoid displacement when subjected to external forces. The baffle plate 209 can only move towards the first limiting block 204 along with the second limiting block 205, thereby ensuring the blocking effect of the baffle plate 209 on the packaging frame.

[0038] Specifically, as shown in Figures 2-3 , Figure 6 , the both ends of the base frame 202 are provided with connecting rods 217 parallel to the width direction thereof. The both ends of the connecting rod 217 are slidingly fitted on the base frame 202, and the two second limiting blocks 205 at the same end are sleeved on the same connecting rod 217. The outer side of the first limiting block 204 is provided with a first screw rod 218, and the second limiting block 205 is sleeved on the first screw rod 218 and locked by a nut. The second limiting block 205 can be moved by loosening the nut, and under the action of the connecting rod 217, the two second limiting blocks 205 can only move synchronously towards the first limiting block 204. Then, the second limiting block 205 is locked by the nut.

[0039] Specifically, as shown in Figures 2-3 , Figure 6As shown, the first limiting block 204 is provided with a vertical rod 219 at the top, which is arranged in the side plate 201, so that the first limiting block 204 and the side plate 201 can move synchronously, and under the driving of the first screw rod 218, the second limiting block 205 also moves synchronously, so as to ensure that the limiting rod 208 is flush with the inner wall of the collecting frame 102.

[0040] For the movement of the side plate 201, the two side plates 201 can be directly connected to the moving end of a bidirectional linear mechanism, such as a bidirectional air cylinder mechanism, or the first limiting block 204 in each through portion 101 can be connected by a connecting plate, and then the connecting plate is connected to the moving end of a bidirectional linear mechanism, which also can realize the synchronous movement of the side plate 201 and the first limiting block 204.

[0041] Specifically, as shown in Figure 1 , Figures 8-9 , the positioning rod 303 is sleeved on the second screw rod 305 and locked by a nut, and the position of the positioning rod 303 can be adjusted by loosening the nut, and then the positioning rod 303 is locked by the nut to fix the positioning rod 303. The second screw rod 305 is installed at both ends of the connecting block 306, the connecting block 306 is connected to the moving end of the first linear mechanism, the first linear mechanism is installed on the moving plate 302 and arranged along the width direction of the moving plate 302. By driving the connecting block 306 to move through the first linear mechanism, the positioning rod 303 can be driven to move along the width direction of the moving plate 302, so as to further adjust the position of the positioning rod 303, so as to adapt to packaging frames of different sizes and ensure that the positioning rod 303 can smoothly pass into the hole of the packaging frame.

[0042] More specifically, as shown in Figures 8-9 , when the positioning rod 303 is locked by the nut, the positioning rod 303 may be deflected under the action of friction, which may cause the end of the positioning rod 303 to be unable to pass into the hole of the packaging frame. Therefore, the side rod 307 is arranged on the upper end of the positioning rod 303 and parallel to the width direction of the moving plate 302, the guide groove 308 is arranged on the side surface of the side rod 307 along the length direction of the side rod 307, the guide rod 309 is arranged in the guide groove 308, and the guide rod 309 is installed on the moving plate 302. Under the action of the guide rod 309, the deflection of the positioning rod 303 is avoided.

[0043] Specifically, as shown in Figure 1 , Figures 8-9As shown, the clamping block 304 is L-shaped, and its upper end is mounted on the drive shaft 310. The drive shaft 310 is rotatably mounted on the support block 311, and one end is connected to the output end of the power equipment. The power equipment is mounted on the support block 311, and the support block 311 is connected to the moving end of the second linear mechanism. The second linear mechanism is mounted on the moving plate 302 and arranged along its width direction. The second linear mechanism drives the support block 311 to move along the width direction of the moving plate 302, and the clamping block 304 moves synchronously with the support block 311, thereby adjusting the clamping block 304 and the moving plate. The distance between the centers of 302 is adjusted to accommodate packaging frames of different widths. When clamping the packaging frame suspended on the conveyor, the rotating plate 301 is rotated 90 degrees, causing the moving plate 302 to face the conveyor. The rotation of the rotating plate 301 can be achieved by connecting its two ends to a rotating shaft, which is then rotatably mounted on a mounting block. One of the rotating shafts is connected to the output of a power device, which drives the shaft to rotate, thereby rotating the rotating plate 301. This causes the moving plate 302 to move towards the conveyor. The movement of 302 can be achieved by installing a third linear mechanism 314 perpendicular to the surface of the rotating plate 301. The moving plate 302 is connected to the moving end of the third linear mechanism 314, which drives the moving plate 302 to move. During the movement of the moving plate 302, the positioning rod 303 passes through the encapsulation frame. Then, the drive shaft 310 is driven to rotate by a power device, causing the clamping block 304 to rotate, so that its short end rotates to the side of the moving plate 302 away from the rotating plate 301, and the short end is parallel to the surface of the moving plate 302, thereby achieving... The packaging frame is clamped, and then the moving plate 302 is moved toward the rotating plate 301 by the third linear mechanism 314. The clamping block 304 moves synchronously with the moving plate 302, thereby removing the packaging frame from the conveying fixture. Then the rotating plate 301 is rotated downward so that the moving plate 302 is below it and both the moving plate 302 and the packaging frame are in a horizontal state. The moving plate 302 is driven downward again by the third linear mechanism 314. Then the clamping block 304 is rotated upward, and the packaging frame will fall onto the support rod 203 under its own gravity.

[0044] Specifically, such as Figures 1-2 As shown, a support plate 103 that moves vertically is provided below the workbench 100. The collection frame 102 is placed on the support plate 103. The collection frame 102 moves synchronously by the up and down movement of the support plate 103, so that the collection frame 102 can enter the rectangular area enclosed by the first limiting block 204 and the second limiting block 205, which provides a limit to prevent it from shifting. After a certain amount of packaging frames are collected in the collection frame 102, the support plate 103 is moved downward and the collection frame 102 is transferred.

[0045] The vertical lifting mechanism, the horizontal linear mechanism, the first linear mechanism, the second linear mechanism and the third linear mechanism used in the application can adopt a driving structure of a telescopic air cylinder or a driving structure of a motor lead screw, as long as the movement of each component can be realized.

[0046] The above merely illustrates the preferred embodiments of the present application, and is not intended to limit the present application. Obviously, various modifications and variations can be made to the present application by those skilled in the art without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the present application claims and their equivalent technologies, the present application is also intended to include these modifications and variations.
