Technical Field

[0001] This application relates to the field of laminating machine technology, specifically to a material discharge device for a laminating machine. Background Technology

[0002] A molding machine is a primary molding device that uses plastic molds to produce various shapes of plastic products from thermoplastic or thermosetting plastics. In the semiconductor industry, after being processed and molded by the molding machine, the wafers (lead frames) need to be fed into a glue-removing mechanism to remove excess glue from the wafers. The wafers are then moved to an unloading mechanism for inspection and collection.

[0003] The finished product inspection and unloading mechanism with announcement number CN218319270U requires the cooperation of a seventh horizontal drive component and a seventh lifting device to drive a seventh baffle to intermittently push the material sheet to the upper rear end of a seventh fixed frame. Then, a seventh robotic arm picks up the material sheet and, in conjunction with a seventh unloading lifting component, places the material sheet into a material box. The seventh robotic arm and the seventh fixed frame are set separately, and when the seventh robotic arm picks up the material sheet for unloading, it needs to move above the seventh fixed frame to pick it up before placing the picked-up material sheet into the material box. However, this structure and arrangement result in a complex overall structure and a large space occupation. Utility Model Content

[0019] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] See Figures 1 to 6 To further elaborate on this application: Combination Figure 1 and Figure 2The material discharge device of the sealing machine includes a stamping unit 5, a transfer unit 4, a conveying unit 1, and an unloading unit 2. The conveying unit 1 is used to convey the material sheet 0, and the unloading unit 2 is used to collect the material sheet 0. The stamping unit 5 is located on the side of the conveying unit 1 away from the unloading unit 2. The transfer unit 4 is located between the stamping unit 5 and the unloading unit 2 and is used to move the material sheet 0 in the stamping unit 5 to the conveying unit 1. The stamping unit 5 is used to cut the semi-finished material sheet 0 and remove excess glue from the semi-finished material sheet 0. The transfer unit 4 and the unloading unit 2 are both integrated on the conveying unit 1.

[0021] Combination Figure 3 The conveying unit 1 includes a support platform 11 and a transfer module 12 disposed on the support platform 11. The support platform 11 has a notch 100 at its end for placing the unloading unit 2. The transfer module 12 is used to move back and forth between the stamping unit 5 and the unloading unit 2 along the x-axis. By arranging the unloading unit 2 in the conveying unit 1, the overall space occupied can be greatly reduced.

[0022] Combination Figure 2 The unloading unit 2 includes a receiving module 21 and a receiving module 22 respectively disposed on the upper and lower sides of the notch 100. The receiving module 21 and the receiving module 22 are arranged opposite to each other. The receiving module 21 can move along the z-axis direction to pick up the material piece 0 on the conveying unit 1 and put it into the receiving module 22.

[0023] Compared with the prior art, this application uses the conveying unit 1 to transport the material piece 0 to the receiving module 21 and the receiving module 22. After the receiving module 21 moves along the z-axis to pick up the material piece 0 on the conveying unit 1, it places the material piece 0 into the receiving module 22 for storage. The overall structure is simple and compact, which can greatly reduce the space occupied.

[0024] Combination Figure 3 In this embodiment, the transfer module 12 includes a movable platform 121 and a positioning plate 122 disposed on the movable platform 121 for placing the material piece 0. The movable platform 121 is connected to a drive mechanism 13, which drives the movable platform 121 to move. The movable platform 121 is slidably connected to the support platform 11. The movable platform 121 and the support platform 11 can be slidably connected by a slider and a guide rail. When the transfer unit 4 places the material piece 0 on the positioning plate 122, the drive mechanism 13 drives the transfer module 12 to move the material piece 0 toward the unloading unit 2.

[0025] As a feasible implementation method, combined with Figure 3The driving mechanism 13 includes a power component and a transmission assembly, as well as a connecting block connecting the transmission assembly and the transfer module 12. The power component drives the transmission assembly to move the transfer module 12. The power component can be a motor; the transmission assembly is a belt drive structure, which is low-cost. Compared to existing technologies, this application uses the driving mechanism 13 to drive the material sheet 0 placed on the movable platform 121 to move quickly to the unloading unit 2, thereby improving conveying efficiency and simplifying the structure. In embodiments not shown, the transmission assembly can also be a screw mechanism or chain drive, etc.

[0026] Combination Figure 4 The receiving module 21 includes a picking and placing mechanism 211 and a picking and placing clamp 212 connected to the picking and placing mechanism 211. The picking and placing clamp 212 can open and close along the x-axis to pick up or place the material piece 0. The picking and placing mechanism 211 is used to drive the picking and placing clamp to move along the z-axis; wherein, the picking and placing mechanism 211 can be a cylinder; of course, the picking and placing mechanism 211 can also be a lead screw mechanism or other linear drive mechanism; compared with the prior art, the receiving module 21 only needs to move along the z-axis and does not need to move along the x-axis, therefore, the overall structure is simpler, the space occupied can be reduced, and the receiving efficiency can be greatly improved.

[0027] During material collection, the pick-and-place mechanism 211 drives the pick-and-place clamp 212 to move along the z-axis direction to pick up the material piece 0 on the positioning plate 122; when the transfer module 12 moves out of the notch 100, the pick-and-place mechanism 211 drives the pick-and-place clamp 212 to place the picked-up material piece 0 into the material release mechanism through the notch 100.

[0028] Combination Figure 5 The pick-and-place fixture 212 includes a mounting plate 2121, and a gripping assembly 2122 and a pressing assembly 2123 disposed on the mounting plate 2121. The gripping assembly 2122 can open and close along the x-axis to pick up and place the sheet 0, and the pressing assembly 2123 can move along the z-axis to cooperate with the gripping assembly 2122 to fix the sheet 0 and prevent the sheet 0 from shaking. Of course, the gripping assembly 2122 can also open and close along the y-axis to pick up and place the sheet 0.

[0029] In this embodiment, the pressing assembly 2123 includes a pressing plate 2124, an elastic component 2125, and a limiting ring 2127. A guide rod 2126 connects the pressing plate 2124 and the limiting ring 2127. The guide rod 2126 is slidably connected to the mounting plate 2121. The elastic component 2125 can push the pressing plate 2124 to press the material piece 0. The elastic component 2125 abuts against the pressing plate 2124 and the mounting plate 2121. The pressing plate 2124 and the limiting ring 2127 are located on the upper and lower sides of the mounting plate 2121, respectively. When the clamping assembly 2122 clamps the material piece 0, the pressing plate 2124, through the elastic component 2125, fixes the material piece between the pressing plate 2124 and the clamping assembly 2122, thereby preventing the material piece 0 clamped by the clamping assembly 2122 from falling off during movement.

[0030] Combination Figure 5 As one feasible implementation, the gripping assembly 2122 includes at least one opening and closing assembly. A plurality of claws are respectively provided on both sides of the opening and closing assembly, forming a gripping area between the claws for accommodating the material sheet 0 and the pressing assembly 2123. The opening and closing assembly is used to drive the claws to close or open along the x-axis direction, thereby gripping or releasing the material sheet 0. The opening and closing assembly can be a finger cylinder, and a support frame is provided between the gripper and the finger cylinder. The claws support the material sheet 0; the claws are connected to the support frames, which are arranged parallel to each other. The positioning plate 122 has clearance grooves that match the claws. In embodiments not shown, the gripping assembly 2122 can also use existing clamps.

[0031] In some embodiments, the width of the pressure plate 2124 is the same as that of the sheet 0; when the clamping component 2122 clamps the sheet 0, the claws retract and abut against both sides of the pressure plate 2124, and the pressure plate 2124 can protect the sheet 0 and prevent it from being damaged.

[0032] Combination Figure 4The receiving module 22 includes a bracket 221, a material box 222, and a support plate 223 that can move within the material box 222 along the z-axis. It is used to receive material pieces 0 and gradually place them into the material box 222. The bracket 221 has a lifting module 23 at its bottom, which drives the support plate 223 to move along the z-axis. The bracket 221 has a placement area for the material box 222. The lifting module 23 can drive the support plate 223 to the top opening of the material box 222 to receive material pieces 0 and avoid damage. For each material piece stacked on the support plate 223, the lifting module 23 drives the support plate 223 to move downwards by the height of one material piece 0, gradually placing the material pieces into the material box 222 until the box is full. Then, the support plate 223 is removed from the material box 222.

[0033] The bottom of the material box 222 is provided with a clearance groove for the support plate 223 to pass through; a baffle may be provided inside the material box 222, and the support plate 223 can push the baffle to move inside the material box 222 to receive the material sheet; when the support plate 223 moves out of the material box 222, the baffle can cover the clearance groove to prevent the material sheet from falling out of the material box 222.

[0034] Combination Figure 4 As one feasible implementation, the lifting module 23 includes a lifting assembly and several push rods. The push rods connect the lifting assembly and the support plate 223, and a connecting plate connects the lifting assembly and the push rods. The lifting assembly can be a lead screw assembly. Of course, the lifting assembly can also be a cylinder or other linear drive mechanism.

[0035] In this embodiment, a detection module 3 is also included. The detection module 3 is used to detect the material sheet 0 on the transfer module 12. The detection module 3 is located above the conveying unit 1. When the conveying unit 1 conveys the material sheet 0 to the unloading unit 2, the detection module 3 can take pictures of the material sheet 0 on the conveying unit 1 to detect defects and incomplete filling of the material sheet 0.

[0036] Combination Figure 6In this embodiment, the transfer unit 4 includes side plates 41 and a clamping module 43 disposed between the side plates 41. A first driving component 44 for driving the clamping module 43 to move along the x-axis and a second driving component 45 for driving the clamping module 43 to move along the z-axis are provided between the clamping module 43 and the side plates 41. The first driving component 44 drives the clamping module 43 to extend into the stamping unit 5, and the second driving component 45 drives it to move closer to or away from the material sheet 0 inside the stamping unit 5, or closer to the transfer module 12. The clamping module 43 is connected to the second driving component 45, and the second driving component 45 is connected to the first driving component 44. The clamping module 43 can adopt the structure of the pick-and-place fixture 212; of course, the clamping module 43 can also adopt existing fixtures.

[0037] In some embodiments, a cleaning module 42 is further included, which is disposed at the front end of the transfer unit 4. The cleaning module 42 includes a cleaning component and a suction unit. The cleaning component is disposed on the suction unit and is used to clean the stamping unit 5. After the stamping unit 5 finishes processing the semi-finished material, the transfer unit 4 extends into the stamping unit 5 to pick up the material sheet 0. During the process of the transfer unit 4 moving out of the stamping unit 5, the cleaning component cleans the stamping unit 5, and simultaneously the suction unit removes the cleaned impurities.
