Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor packaging, in particular to a material collecting plate pushing device which is anti-bending. Background Art

[0002] In the semiconductor chip packaging production line, finished chips need to be collected in batches onto a collection board for easy packaging and transportation. When loading materials on an empty collection board, the single collection board needs to be pushed to the subsequent processing equipment. Generally, the collection board is a thin copper sheet. When pushing materials, due to the influence of force factors, the collection board will be unevenly stressed and arched. After continuing to push materials, the collection board will be deformed or even broken.

[0003] Therefore, it is necessary to further improve the structure of the material collecting plate pushing device. Utility Model Content

[0004] The utility model aims to provide a material collecting plate pushing device which is anti-bending and can push materials piece by piece more stably.

[0005] In order to achieve the above-mentioned utility model purpose, the utility model provides a material collection plate pushing device with anti-bending, including a frame, a driven block, a connecting block, a spring, a pushing rod, a transmission mechanism, and a motor;

[0006] The frame is provided with a guide rod, and the driven block is connected to the guide rod; the connecting block is connected to the transmission mechanism through the driven block, and the transmission mechanism includes a connecting rod, a roller, and a transmission block, the transmission block is connected to the bottom of the driven block, the transmission block is provided with a connecting groove, and the roller is rollingly arranged in the connecting groove through the connecting rod; the connecting rod is connected to the motor;

[0007] The connecting block is provided with a clearance hole, one end of the push rod is connected to the connecting block through the spring and is located in the clearance hole; the other end of the push rod is provided with an insertion groove.

[0008] Preferably, the end of the insertion slot is provided with a bevel.

[0009] As a further improvement of the utility model, the push rod is provided with a sensing rod, the connecting block is provided with a sensor, and the connecting position of the sensor is matched with the position of the sensing rod.

[0010] As a further improvement of the utility model, it also includes an adjustment mechanism, which includes a fixed block, a movable block, and an adjustment screw.

[0011] Furthermore, the movable block is provided with a through hole, and the fixed block is provided with a limiting rod which passes through the through hole.

[0012] A pusher device for anti-bending aggregate plates of the present utility model arranges a push rod on one side of several stacked aggregate plates. The connecting rod rotates alternately forward and backward under the action of a motor. While the roller connected thereto rolls in the connecting groove, it provides a force to the transmission block, so that the driven block connected to the transmission block makes a linear reciprocating movement along the guide rod, and the push rod reciprocates accordingly, pushing the single aggregate plate at the bottom of the stacked several aggregate plates, and pushing it onto the welding equipment. During the pushing process, if abnormal pushing occurs, the spring connected to the push rod plays a buffering role to avoid excessive force on the aggregate plate and damage.

[0021] The following further details the detailed embodiments of the present utility model in conjunction with the drawings.

[0022] As Figure 1-2 shown, an anti-bending aggregate plate pusher device of the present utility model includes a frame 1, a driven block 2, a connecting block 3, a spring 32, a push rod 4, a transmission mechanism 5, and a motor 8;

[0023] The frame 1 is provided with a guide rod 11, and the driven block 2 is connected to the guide rod 11; the connecting block 3 is connected to the transmission mechanism 5 through the driven block 2. The transmission mechanism 5 includes a connecting rod 51, a roller 52, and a transmission block 53. The transmission block 53 is connected to the bottom of the driven block 2. The transmission block 53 is provided with a connecting groove 54, and the roller 52 is rollingly arranged in the connecting groove 54 through the connecting rod 51; the connecting rod 51 is connected to the motor 8;

[0024] As Figure 3 shown, the connecting block 3 is provided with a relief hole 31. One end of the pusher rod 4 is connected to the connecting block 3 through a spring 32 and is located in the relief hole 31;

[0025] As Figure 4-5 shown, the other end of the pusher rod 4 is provided with an insertion groove 42. During insertion, the insertion groove 42 pushes the aggregate plate 8 through the insertion groove 42. The end of the insertion groove 42 is provided with an inclined edge 43. When the pusher rod 4 touches the aggregate plate 8, the aggregate plate 8 enters the insertion groove 42 along the inclined edge 43, and the inclined edge 43 plays a guiding role.

[0026] When the pusher rod 4 pushes the aggregate plate 8, due to the factor of the force application point, the aggregate plate 8 may be subjected to excessive force and arch or bend. The spring 32 provides a buffering effect for the pusher rod 4, so that when the pusher rod 4 encounters resistance when pushing the aggregate plate 8, it can retract within a small range, that is, the pusher rod 4 moves into the relief hole 31.

[0027] The pusher rod 4 is provided with an induction rod 41, and the connecting block 3 is provided with a sensor 7. The connection position of the sensor 7 is adapted to the position of the induction rod 41. The sensor 7 can be an existing photoelectric sensor. When the pusher rod 4 moves into the relief hole 31 under the action of the spring 32, the induction rod 41 moves accordingly. When the induction rod 41 enters the sensing range of the photoelectric sensor, it indicates that the buffering stroke range of the pusher rod 4 has exceeded the preset range. The sensor 7 converts the sensed optical signal into an electrical signal and transmits it to the terminal, so that the terminal can immediately receive the abnormal information and the operator can handle it in time.

[0028] The adjusting mechanism 6 includes a fixed block 61, a movable block 62, and an adjusting screw 63. The fixed block 61 is connected to the driven block 2. The bottom of the connecting block 3 is connected to the movable block 62. The fixed block 61 is connected to the movable block 62 through the adjusting screw 63. During debugging, according to the position of the aggregate plate 8, the initial position of the pusher rod 4 can be adjusted to ensure that the pusher rod 4 is in a suitable pushing position. The adjusting screw 63 can be screwed, and the movable block 62 drives the connecting block 3 and the driven block 2 to move along the guide rod 11, thereby realizing the position adjustment of the pusher rod 4.

[0029] The movable block 62 is provided with a through hole 65, and the fixed block 61 is provided with a limiting rod 64 which passes through the through hole 65. During the position adjustment, the movable block 62 moves along the limiting rod 64. Since the thickness of the single-piece aggregate plate 8 is relatively thin and the precision requirement for the pushing position of the pushing rod 4 is relatively high, therefore, on the premise of the guiding function of the guiding rod 11, the limiting rod 64 further plays a limiting role to prevent the pushing rod 4 from being skewed during the position adjustment, which affects the docking with the aggregate plate 8.

[0030] A kind of aggregate plate pushing device for preventing bending of the present utility model, the pushing rod 4 is arranged on one side of several stacked aggregate plates 8. The connecting rod 51 rotates alternately forward and backward under the action of the motor 8. While the roller 52 connected thereto rolls in the connecting groove 54, it provides a force to the transmission block 53, so that the driven block 2 connected to the transmission block 53 makes a linear reciprocating movement along the guiding rod 11, and the pushing rod 4 reciprocates accordingly, pushing the single-piece aggregate plate 8 at the bottom of several stacked aggregate plates 8 into a pile and pushing it onto the welding equipment. During the pushing process, if abnormal pushing occurs, the spring 32 connected to the pushing rod 4 plays a buffering role to avoid excessive force on the aggregate plate 8 and damage.

[0031] The preferred embodiments of the present utility model have been specifically described above, but the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent variations or substitutions without departing from the spirit of the present utility model, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
