Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor processing, in particular to a feeding box and a feeding mechanism of a semiconductor cutting and forming machine. Background Art

[0002] The loading mechanism of the existing semiconductor rib cutting and forming equipment includes a strip pushing mechanism, a material box lifting mechanism, a material box conveying mechanism, a feeding track mechanism, a robotic arm, and a material box discharging mechanism, and the above steps are as follows: several material boxes loaded with copper plates are placed in the material box conveying mechanism, and the cylinder in the material box conveying mechanism pushes the toothed material boxes into the material box lifting mechanism in sequence. The material box lifting mechanism drives the material box to move after detecting that the material box is pushed into place. When the center of the lower lead frame in the material box is consistent with the center of the push rod in the strip pushing mechanism, the material box lifting mechanism stops moving, and the cylinder in the strip pushing mechanism drives the push rod to push the lead frame in the material box into the feeding track mechanism. The feeding track mechanism passes through the roller The wheel sends the lead frame to the grasping position of the robotic arm, and the manipulator in the robotic arm grasps the lead frame for loading. When all the lead frames in the material box are pushed out, the material box lifting mechanism drives the material box to the material box discharge position, and the empty material box is pushed out through the material box discharge mechanism. For the loading mechanism of the above-mentioned rib cutting and forming equipment, it places multiple material boxes on the temporary material box conveying mechanism at one time, and then conveys the material boxes in sequence (pushing them one by one, and when all the copper plates in the pushed material box are pushed out, the next material box is pushed), which can reduce the frequency of loading and unloading of materials by staff during the operation of the equipment, but its continuity is poor, which is not conducive to improving the working efficiency of the equipment.

[0003] In response to the above problems, it was found that the Chinese patent with the announcement number CN218230850U discloses a continuous conveying assembly for loading plate material boxes. The continuous conveying assembly adopts the method of placing the material box on a conveyor with a limited position frame (the document states that a belt conveyor device can be used as a conveyor for conveying). Its operation can greatly improve the continuity of work. However, there are some problems in the use of the continuous conveying assembly. Figure 3 From its working principle, it can be seen that its material box (spacers are arranged at equal intervals in the material box, and the plates are placed in the gap between the two spacers for loading) is a ring-shaped structure with openings at both ends, and is slidably connected by a limit frame. Since the two open ends of the material box do not have a mechanism to block the two ends of the plates, when the empty material box is replaced as a whole (whole-piece replacement is more convenient and faster than loading single plates in sequence, and most of the time, whole-piece replacement is adopted), it is easy for the material box to tilt during installation, causing the internal plates to move and slide due to gravity; at the same time, the material box loaded with plates is also easy to cause the internal plates to move and slide during manual transportation (that is, transporting the loading box loaded with plates to the processing point) or when the conveying mechanism drives the loading box to do a ring-shaped movement. Therefore, the present application provides a loading box and loading mechanism for a semiconductor cutting and forming machine to meet the needs. Summary of the Invention

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example: Reference Figure 1-2 The loading box of a semiconductor cutting and forming machine shown in the figure includes a loading box 1 with openings at both ends, and a plurality of supporting strips 3 are correspondingly arranged on the two inner walls of the loading box 1. It is characterized in that: the rear end of the loading box 1 is vertically fixed with two baffles 4 for blocking the rear end of the plate, and a pushing gap 5 is installed between the two baffles 4, and it also includes a blocking unit 2 that can change the blocking state for blocking the front end of the plate. The loading box can limit the front and rear ends of the plate in the loading box 1 through the two baffles 4 and the blocking unit 2, so that when it is replaced and installed as a whole, the plate will not slip due to the tilting of the loading box 1, and for the removed empty loading box 1 (at this time, the matching loading mechanism has released the blocking of the blocking unit 2 on the front end of the plate), the plate can be directly inserted into the loading box 1 from the front and rear openings of the loading box 1. After completion, the front end of the plate is blocked by the blocking unit 2 (this loading box 1 is reserved), which can effectively prevent the plate from slipping out of the loading box 1.

[0032] It should be noted that when the loading box 1 is transported to a specific loading position, the loading mechanism used in conjunction with it automatically releases the blocking unit 2 from blocking the front end of the plate, so that the subsequent loading operation of the plate can be carried out.

[0033] As a preferred implementation in this embodiment, Figure 3-5 As shown, the blocking unit 2 includes two U-shaped baffles 21 slidably arranged at the front end of the loading box 1 and a shell 23 fixedly arranged at the upper end of the loading box 1. A pressing column 24 is movably provided in the inner cavity of the shell 23, and the pressing column 24 is located at the end of the inner cavity of the shell 23 and is fixedly connected to the mounting plate 26. Both ends of the mounting plate 26 are rotatably provided with movable rods 22, and the lower ends of the two movable rods 22 pass through the movable openings provided at the upper end of the loading box 1 and are rotatably connected to the corresponding U-shaped baffles 21. A return spring 25 is sleeved on the pressing column 24, and the upper and lower ends of the return spring 25 are fixedly connected to the shell 23 and the mounting plate 26 respectively. A rotating rod 27 is rotatably provided on the front end of the mounting plate 26, and a cylinder 28 is fixedly provided on the rotating rod 27, and a first cross-section is provided above and below the cylinder 28. A self-locking block 29 and a second self-locking block 210, and a movement gap adapted to the cylinder 28 is provided between the first self-locking block 29 and the second self-locking block 210; a first inclined surface section 15, a second inclined surface section 17 and a third inclined surface section 13 are respectively provided on the opposite ends of the first self-locking block 29 and the second self-locking block 210, the second inclined surface section 17 located on the second self-locking block 210 is connected to the third inclined surface section 13 through a linear transition section 14, the upper end surface of the first self-locking block 29 is set to the fourth inclined surface section 16, the connection point position of the first inclined surface section 15 and the second inclined surface section 17 located on the first self-locking block 29 is located on the vertical axis of the rotating rod 27, and the connection point position of the first inclined surface section 15 and the second inclined surface section 17 located on the second self-locking block 210 is located on the left side of the vertical axis of the rotating rod 27.

[0034] When in use, when the loading box 1 is transported to a specific position (such as Figure 7As shown, the leftmost loading box 1 position) can be automatically squeezed by the loading mechanism used with it to press the pressing column 24 downward, and the downward movement of the pressing column 24 will drive the two movable rods 22 to drive the two U-shaped blocking bars 21 to open outward. At this time, the lower end of the cylinder 28 on the rotating rod 27 will contact the fourth inclined surface segment 16 of the first self-locking block 29 and slide downward along its inclined surface. When the cylinder 28 slides to the entrance of the movement gap between the two first inclined surface segments 15, the gravity of the rotating rod 27 and the cylinder 28 is applied. This will cause the cylinder 28 to rotate to the right and eventually move into the movement gap (when the cylinder 28 slides down a certain distance along the fourth inclined surface section 16, the two U-shaped blocking bars 21 have already released the blockage of the front end of the plate). At this time, the pressing column 24 is released, and the elastic force of the return spring 25 will cause the rotation-seeking rod 27 to slide upward along the second inclined surface section 17 on the first self-locking block 29, and finally stop at the junction of the first inclined surface section 15 and the second inclined surface section 17 on the first self-locking block 29. At this time, the two U-shaped blocking bars 21 are still unable to move. The front end of the plate is blocked, and the U-shaped blocking bar 21 is restricted and cannot move. At this time, the feeding mechanism moves the plate out of the feeding box 1 and pushes it out. The empty feeding box 1 can be removed as a whole, and the plate diameter can be installed in the feeding box 1. When it is necessary to block the front end of the plate, the pressing column 24 can be pressed manually. At this time, the lower end of the cylinder 28 moving vertically downward will contact the second inclined surface section 17 on the second self-locking block 210, and slide downward along the inclined surface of the second inclined surface section 17, and finally slide to the end of the transition section 14. At this time, Release the pressing column 24, and under the action of the elastic force of the return spring 25 and the gravity of the rotating rod 27, the cylinder 28 makes an upward parabolic motion, contacts the third inclined surface section 13 of the first self-locking block 29 and moves upward along its inclined surface, and finally the gravity of the rotating rod 27 restores the cylinder 28 to its original position. At this time, the two U-shaped baffles 21 form a block on the front end of the plate, and then cooperate with the two baffles 4 to limit the plate in the loading box 1. The blocking unit can block and release the front end of the plate by pressing, and the operation is convenient and simple.

[0035] The point that needs to be noted is that, first, the setting of the transition section 14 is to increase the rightward offset of the cylinder 28 to prevent the cylinder 28 from moving into the movement gap between the two second inclined surface sections 17 when the cylinder 28 makes an upward parabolic motion; second, to ensure the rapid reset of the rotating rod 27, an L-shaped mounting strip 18 can be provided at the bottom of the mounting plate 26, and the L-shaped mounting strip 18 is located at the rear side of the rotating rod 27, and a magnetic block 19 arranged coaxially with the cylinder 28 is fixed on the L-shaped mounting strip 18. The magnetic block 19 arranged thereon can attract the cylinder 28 through magnetic action, so that the rotating rod 27 can quickly return to its original position and maintain this state stably, to prevent the rotating rod 27 located on the first self-locking block 29 from rocking back and forth due to gravity when multiple pressings are performed continuously, which makes it impossible for the cylinder 28 to move downward along the fourth inclined surface section 16, and ultimately makes it impossible to release the blocking unit 2 from blocking the front end of the plate.

[0036] As a preferred implementation in this embodiment, Figure 5 As shown, the distance between the two second inclined surface segments 17 gradually decreases from left to right and decreases to the same as the diameter of the cylinder 28, which can prevent the cylinder 28 from moving into the movement gap between the two second inclined surface segments 17 when performing an upward parabolic motion. Multiple protection settings are set to prevent the cylinder 28 from moving leftward into the movement gap between the two second inclined surface segments 17.

[0037] It should be noted that the movement gap between the two oppositely arranged first inclined surface sections 15 is larger than the diameter of the cylinder 28 , so that the cylinder 28 can easily enter the movement gap between the two first inclined surface sections 15 under the action of gravity of the rotating rod 27 .

[0038] refer to Figure 7 A feeding mechanism includes a side baffle 11 with a through-hole, a conveying mechanism 6 installed with several limit frames 7, an electric telescopic rod 12 and a pushing component 10. A lifting hole 8 is opened at one side end of the limit frame 7. A limiting unit is set in the limit frame 7 for limiting the feeding box 1. A lifting block that is compatible with the lifting hole 8 is fixed to the upper end of the output shaft of the electric telescopic rod 12. The limit also includes an adjustment unit 9 for straightening the feeding box 1 and controlling the blocking unit 2 to release the blockage of the front end of the lead frame.

[0039] As a preferred implementation in this embodiment, Figure 8As shown, the adjustment unit 9 includes an upper extrusion plate 97 and a lower extrusion plate 98 arranged in an upper and lower manner. The lower extrusion plate 98 is slidably penetrated by the electric telescopic rod 12. The lower end of the lower extrusion plate 98 and the output end of the electric push rod 99, the upper extrusion plate 97 and the lower extrusion plate 98 are both slidably arranged on two columns 91 arranged on the same side, and a mounting block 92 is fixedly provided on the two columns 91. A cross bar 93 is fixedly provided on the mounting block 92, and two sliding sleeves 94 are slidably provided on the cross bar 93, and the two sliding sleeves 94 are movably connected to the upper extrusion plate 97 and the lower extrusion plate 98 respectively through four connecting rods 95. A lower pressing block 96 is fixed to the side end of the upper extrusion plate 97. When the conveying mechanism 6 moves the loading box 1 carrying the plate to a specific position (such as Figure 7 As shown in the leftmost loading box position, the limit frame 7 moves to between the upper extrusion plate 97 and the lower extrusion plate 98). At this time, the electric push rod 99 works. As the output end of the electric push rod 99 extends upward, the lower extrusion plate 98 can be driven to move upward. Through the cooperation of the sliding sleeve 94, the connecting rod 95 and the cross bar 93, the lower extrusion plate 98 and the upper extrusion plate 97 can be made to move together relative to each other, so that the upper extrusion plate 97 and the lower extrusion plate 98 can respectively squeeze and fix the upper and lower sides of the limit frame 7, and the inclined limit frame 7 can be tilted. When the lifting plate 1 is lifted, the upper and lower pressing blocks 96 are separated from the pressing column 24, and the two U-shaped blocking bars 21 can no longer block the front end of the plate, and the plates in the loading box 1 are pushed in turn. When all the plates are pushed, the electric push rod 99 controls the upper extrusion plate 97 and the lower extrusion plate 98 to move backwards, releasing the limit frame 7. When the empty loading box 1 moves to the loading position, the personnel can directly load the plates into the upper loading box 1 (after loading, the pressing column 24 needs to be pressed so that the two U-shaped baffles 21 block the front end of the plates), or directly remove it and replace it with the loading box 1 fully loaded with plates.

[0040] It should be noted that: First, the conveying mechanism in the existing patent document CN218230850U adopts a belt conveyor. Whether it adopts a belt conveyor or a chain plate conveyor (which is driven by gears and chains) or other conveying devices, there is a problem. Due to the easy deformation of the belt and the processing accuracy of the gears and chains, when the limiting frame 7 carrying the loading box 1 rotates to a specific position (i.e., the plate loading position, such as Figure 7 The lifting block 7 can be a magnetic part, which can be fixed with the loading box 1 by magnetic adsorption to ensure the stability of the loading box 1 during pushing. Third, the length of the limit frame 7 is less than that of the loading box 1, so that after the loading box 1 is installed on the limit frame 7, the pressing column 24 thereon is located outside the limit frame 7, to prevent the pressing column 24 from contacting and colliding with the inner wall of the limit frame 7 when the conveying mechanism 6 moves.

[0041] As a preferred implementation in this embodiment, Figure 10 As shown, the limiting unit includes several telescopic rods 74 with extrusion springs 72 installed inside, and a ball 71 is installed on the upper end of each telescopic rod 74. Several telescopic rods 74 are respectively installed in a plurality of grooves provided on the inner wall of the limiting frame 7, and a limiting slide groove adapted to the ball 71 is provided on the outer wall of the loading box 1. The limiting unit can limit the forward and backward movement of the loading box 1 without affecting its left and right movement (that is, it does not affect its sequential loading operation), which is beneficial to prevent the loading box 1 from slipping off the limiting frame 7.

[0042] As a preferred implementation in this embodiment, Figure 9 As shown, a plurality of L-shaped blocking rods 73 are vertically provided on one end of the limit frame 7. When the loading box 1 is plugged and installed on the limit frame 7, the L-shaped blocking rods 73 can contact the outer wall of the baffle 4 to prevent it from being pushed out during insertion.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
