Description

Technical Field

[0001] The present invention relates to the technical field of laser film opening equipment, and particularly relates to a blanking device for a laser film cutting device. Background Art

[0002] Laser film opening is a technology applied to semiconductor chips for cutting specific areas of the covered TSA resin-based film. It removes the film layer on the chip by using a laser beam to open the contact channels. In current laser film opening equipment, after laser film opening of the chip, generally a manipulator is used to grab the chip and place it on a transfer table, and then a pusher device is used to translate the chip into a magazine. The magazine is clamped on a gripping device, and the gripping device is fixed on a cross slide that can move up and down and back and forth. The gripping device includes a mounting frame fixed on a slider that slides up and down on the cross slide. Upper and lower chucks are respectively installed on the upper and lower sides of the mounting frame. The lower chuck is fixed to the lower part of the mounting frame by screws, and the upper chuck is slidably installed above the mounting frame up and down. The upper chuck is controlled to lift and lower by a cylinder. After the magazine is positioned above the lower chuck, the upper chuck is lowered by using the cylinder to clamp. During the chip receiving process, the magazine relies on the push rod of the cylinder to move downwards so that the magazine is clamped between the upper and lower chucks. When the cylinder is used for a long time, the piston seal ring or O-ring inside it may age and wear, resulting in air leakage inside the cylinder and unstable pressure, or the push rod may retract due to insufficient air source pressure or fluctuations, which may cause the upper chuck to suddenly move upwards under the action of the cylinder. The upwards moving upper chuck may cause the magazine to be clamped unstably, or even cause the magazine to fall between the upper and lower chucks, and then the chips inside it may scatter and be damaged. Therefore, a blanking device for a laser film cutting device is designed. Summary of the Invention

[0003] A blanking device for a laser film cutting device proposed by the present invention solves the problem that the gripping device fails to be fixedly opened during the clamping process, resulting in the fall of the magazine.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A blanking device for a laser film cutting device includes a base. A transfer table is installed above the base. A pusher group is installed on the front side of the transfer table. A magazine blanking group is arranged on the right side of the pusher group. The magazine blanking group includes a discharge conveyor belt installed on the base. A feeding conveyor belt is installed above the discharge conveyor belt through a bracket. A magazine is placed on the feeding conveyor belt. A cross slide is installed at the rear of the magazine blanking group. A clamping mechanism for clamping the magazine is installed on the slider of the cross slide. An anti-fall mechanism is installed on the left side of the cross slide. The anti-fall mechanism is movably connected to the clamping mechanism. An alarm mechanism for restricting the lifting and lowering of the clamping mechanism is also installed on the anti-fall mechanism;

[0006] The clamping mechanism includes a lifting plate fixed on the vertical slider of the cross slide. A lower chuck is fixed below the front side of the lifting plate. An installation top plate is fixed at the top of the lifting plate. Four pressing rods distributed in a rectangular structure are slidably inserted up and down through the installation top plate. The lower ends of the pressing rods are below the installation top plate and are connected with an upper chuck. A pressing spring is sleeved on the pressing rod, and the upper and lower ends of the pressing spring are respectively abutted against the upper chuck and the installation top plate. A jacking cylinder is installed on the front side of the lifting plate. In the normal state, the push rod of the jacking cylinder extends and pushes the upper chuck to move upward, and the pressing spring makes the upper chuck tend to move downward;

[0007] The anti-falling mechanism includes a moving base arranged on the left side of the cross slide. A moving slide is slidably installed back and forth above the moving base. The moving slide is fixed to the horizontal slider of the cross slide by screws. An offset plate is slidably arranged left and right above the moving slide. A vertical frame is vertically fixed on the offset plate. A lifting frame is slidably installed up and down on the right side of the vertical frame, and the lifting frame is slidably connected to the left and right with the lifting plate. An lifting connection plate is fixed above the right side of the lifting frame. A jacking frame is slidably installed up and down above the lifting connection plate. A floating part is slidably installed in the jacking frame. The jacking frame is slidably connected to the lower surface of the upper chuck. Two round holes are formed through the lifting connection plate up and down. Guide columns are slidably inserted up and down in the round holes. The top ends of the guide columns are fixed to the jacking frame, and a limit ring is further arranged at the bottom end of the guide column. The design of the limit ring makes the jacking frame not break away from the lifting connection plate;

[0008] Two groups of strip-shaped sliding openings are formed through the upper and lower surfaces of the jacking frame. Long rods are welded to the lower end of the upper chuck. The two long rods respectively pass through the two groups of strip-shaped sliding openings and are below the jacking frame. And a round sleeve is fixed by screws on the part of the long rod below the jacking frame. The round sleeve is in sliding contact with the jacking frame. The jacking frame is slidably installed below the upper chuck through the long rod and the round sleeve.

[0009] Preferably, the material pushing group includes a horizontal module fixed on the base through a bracket. A lifting part is installed on the slide of the horizontal module. The lifting part includes a lifting cylinder installed on the slide of the horizontal module. A lifting seat is installed on the push rod of the lifting cylinder. A material pushing rod is arranged on the lifting seat. After the chip is laser-cut on the upper layer of the film, it will be grabbed onto the transfer table under the action of the manipulator. The horizontal module moves the lifting part to the left end of the transfer table. Then the material pushing rod descends under the action of the lifting cylinder and pushes the chip to move rightward and be received into the magazine on the right side.

[0010] Preferably, a linear slider is fixed at the left end of the front side of the lifting plate. A linear slide plate is fixed at the right rear side of the lifting frame. A linear slide groove is formed in the linear slide plate. The linear slider is slidably arranged in the linear slide groove. The linear slider is fixed to the lifting plate. The lifting frame is slidably connected to the lifting plate through the linear slide plate and the linear slider.

[0011] Preferably, a moving groove is formed on the upper surface of the moving base. The moving groove includes a straight groove and an extension groove. The extension groove is located at the left front side of the straight groove. The straight groove and the extension groove are communicated through an inclined offset groove. The extension groove is located at the front side of the moving base, and the distance between the extension groove and the cross slide is greater than the distance between the straight groove and the cross slide.

[0012] A strip-shaped offset slide hole is formed through the upper and lower surfaces of the moving slide. An offset roller is installed below the offset plate. The offset roller passes through the offset slide hole and rolls in the moving groove. When the offset roller moves from the straight groove to the offset groove, the offset roller will drive the offset plate to move a certain distance to the left. When it moves into the extension groove, its distance is at the maximum.

[0013] Preferably, a sliding hole is formed through the front and rear of the lifting frame, and a through hole is formed through the upper and lower of the lifting frame, and the through hole is communicated with the sliding hole. The floating member includes a floating plate slidably inserted into the sliding hole from left to right. The right end of the floating plate is connected with a floating spring column. The right end of the floating spring column slidably passes through the lifting frame and is placed outside it. The floating spring column makes the floating plate always have a tendency to move to the left, so that the floating plate is at the leftmost end of the sliding hole when it is not affected by external forces other than the floating spring column.

[0014] Preferably, two through interfaces are formed on the floating plate. The upper chuck is formed with a strip-shaped through opening through the upper and lower parts. The through opening is directly above the through hole and has the same size as it. When the offset roller is in the straight groove, the two through interfaces are directly above the two push rods of the lifting cylinder. When the offset roller is in the offset groove and the extension groove, the through interfaces are designed to be misaligned with the two push rods of the lifting cylinder.

[0015] Preferably, the alarm mechanism includes an alarm component fixed on the discharge conveyor belt. An activity member is installed on the lifting frame. The activity member includes a mounting frame fixed on the lifting frame. A limiting block is slidably installed on the inner side of the mounting frame in the front and rear directions. A fixing plate is fixed on the mounting frame. A reset spring column is slidably installed on the fixing plate in the front and rear directions. The front end of the reset spring column is connected with the limiting block. A limiting member for limiting the limiting block is installed on the clamping mechanism. A strip-shaped opening is formed through the front and rear of the limiting block. A guiding slider is fixed on the mounting frame. The guiding slider is slidably placed in the strip-shaped opening, so that the limiting block can move back and forth, and the reset spring column makes the limiting block always have a tendency to move forward.

[0016] Preferably, the alarm assembly includes a fixed limiting plate fixed on the discharge conveyor belt. One end of the fixed limiting plate away from the discharge conveyor belt is rotatably installed with a deflecting limiting plate through a pin. A torsion spring is sleeved on the pin, and two ends of the torsion spring are respectively connected to the fixed limiting plate and the deflecting limiting plate. A buzzer button is fixed on the upper end of the side of the fixed limiting plate close to the deflecting limiting plate. The buzzer button is electrically connected to an external buzzer. A contact inclined surface is formed by removing a part of the lower side of the side of the deflecting limiting plate close to the mounting bracket, and an offset inclined surface is formed by removing a part of the upper side of the side of the limiting block close to the alarm assembly.

[0017] Preferably, the limiting member includes a fixed bracket fixed above the pressing rod. A limiting rod is fixed below the side of the fixed bracket away from the pressing rod. A limiting groove is opened above the limiting block. When the upper chuck is at the lowest position, the limiting rod is inserted into the limiting groove. The cross section of the limiting groove is in a strip-shaped structure and the overall length is relatively long.

[0018] Advantages of the present invention:

[0019] 1. By arranging a clamping mechanism on the cross slide table, the clamping mechanism uses a pressing spring and a pressing rod to make the upper chuck clamp the magazine. The lifting of the lifting cylinder controls the lifting of the upper chuck, avoiding damage to the magazine caused by excessive clamping force due to a failure of the lifting cylinder. Cooperating with the arranged anti-falling mechanism, the anti-falling mechanism can move horizontally together with the clamping mechanism and make the lifting of the lifting cylinder ineffective. During the clamping process, it avoids the falling of the magazine caused by a failure of the lifting cylinder, improving safety.

[0020] 2. By arranging a floating member in the anti-falling mechanism, when the push rod of the lifting cylinder is inserted into the through interface, the floating plate can move left and right. Even when the offset roller moves to the offset groove and the extension groove, causing the lifting frame to shift to the left, the position of the floating plate will not change, thus avoiding damage to the push rod of the lifting cylinder being pulled by the left-shifted lifting plate and not affecting the normal movement of the cross slide table.

[0021] 3. By arranging an alarm mechanism on the anti-falling mechanism, the alarm mechanism can lift and move horizontally together with the clamping mechanism. When the lifting cylinder fails to open the upper chuck, the clamping mechanism will give an alarm during the rising process, avoiding the situation where the clamping mechanism carries the magazine and moves upward when the magazine full of chips is not placed on the discharge conveyor belt, resulting in the inability of the full magazine to flow out normally.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0034] Refer to Figure 1 - Figure 10 , a blanking device for a laser film cutting device, including a base 1, a transition table 2 is installed above the base 1, a pushing group 3 is installed on the front side of the transition table 2, a magazine blanking group 4 is arranged on the right side of the pushing group 3, and the magazine blanking group 4 includes a discharge conveyor belt 41 installed on the base 1. Above the discharge conveyor belt 41, a feeding conveyor belt 42 is installed through a bracket. The length of the discharge conveyor belt 41 is greater than the length of the feeding conveyor belt 42. After the magazine 6 is above the discharge conveyor belt 41, the clamping mechanism 7 directly moves up and forward, so as to grab the empty magazine 6 above. There is a magazine 6 placed on the feeding conveyor belt 42. A cross slide 5 is installed at the rear of the magazine blanking group 4. A clamping mechanism 7 for clamping the magazine 6 is installed on the slider of the cross slide 5. An anti-falling mechanism 8 is installed on the left side of the cross slide 5. The anti-falling mechanism 8 is movably connected to the clamping mechanism 7. An alarm mechanism 9 for restricting the lifting and lowering of the clamping mechanism 7 is also installed on the anti-falling mechanism 8;

[0035] The clamping mechanism 7 includes a lifting plate 71 fixed on the vertical slider of the cross slide 5. A lower clamp head 77 is fixed below the front side of the lifting plate 71. An installation top plate 72 is fixed at the top of the lifting plate 71. Four pressing rods 73 distributed in a rectangular structure are slidably inserted up and down through the installation top plate 72. The lower end of the pressing rod 73 is below the installation top plate 72 and is connected to an upper clamp head 75. A pressing spring 74 is sleeved on the pressing rod 73. The upper and lower ends of the pressing spring 74 are respectively abutted against the upper clamp head 75 and the installation top plate 72. A jacking cylinder 76 is installed on the front side of the lifting plate 71. The pressing spring 74 is selected as a suspension spring or a thickened round spring. They have a focus on anti-fatigue and dynamic load capacity, stable pressure, are suitable for high-strength scenarios such as heavy-duty equipment, and meet the stability requirements under dynamic loads;

[0036] Under normal conditions, the push rod of the jacking cylinder 76 extends and pushes the upper clamp head 75 to move upward. The pressing spring 74 makes the upper clamp head 75 have a tendency to move downward. There is a large space between the upper clamp head 75 and the lower clamp head 77. After the magazine 6 is above the lower clamp head 77, the push rod of the jacking cylinder 76 moves downward. The upper clamp head 75 moves downward under the action of the pressing spring 74 and clamps the magazine 6 between the upper clamp head 75 and the lower clamp head 77. The jacking cylinder 76 only plays a role in separating the upper clamp head 75 from the magazine 6, and it does not participate in clamping the magazine 6, avoiding damage to the magazine 6 caused by excessive clamping force due to a malfunction of the jacking cylinder 76;

[0037] The anti-falling mechanism 8 includes a moving base 81 arranged on the left side of the cross slide 5. A moving slide 82 is slidably installed front and back above the moving base 81. The moving slide 82 is fixed to the transverse slider of the cross slide 5 by screws. An offset plate 831 is slidably arranged left and right above the moving slide 82. A vertical frame 83 is vertically fixed on the offset plate 831. A lifting frame 84 is slidably installed up and down on the right side of the vertical frame 83, and the lifting frame 84 is slidably connected left and right with the lifting plate 71. A lifting connection plate 841 is fixed above the right side of the lifting frame 84. A jacking frame 85 is slidably installed up and down above the lifting connection plate 841. A floating member 86 is slidably installed in the jacking frame 85. The jacking frame 85 is slidably connected with the lower surface of the upper chuck 75. Two circular holes are formed through the lifting connection plate 841 up and down. A guide post 842 is slidably inserted up and down in the circular holes. The top end of the guide post 842 is fixed to the jacking frame 85, and a limit ring is further arranged at the bottom end of the guide post 842. The design of the limit ring prevents the jacking frame 85 from detaching from the lifting connection plate 841;

[0038] Two groups of strip-shaped sliding openings 853 are formed through the upper and lower surfaces of the jacking frame 85. Long rods are welded to the lower end of the upper chuck 75. The two long rods respectively pass through the two groups of strip-shaped sliding openings 853 and are located below the jacking frame 85. A round sleeve is fixed by screws to the part of the long rod located below the jacking frame 85. The round sleeve is in sliding contact with the jacking frame 85. The jacking frame 85 is slidably installed below the upper chuck 75 through the long rod and the round sleeve.

[0039] Refer to Figure 2 、 Figure 3 As shown in

[0040] Refer to Figure 4 、 Figure 5 and Figure 7 As shown in

[0041] Strip-shaped notches are formed through both the left and right sides of the vertical frame 83. The lifting frame 84 slides on the right side of the vertical frame 83. Two round rods are fixed to the left side of the lifting frame 84. The two round rods pass through the strip-shaped notches and are screwed with a cylinder at the left end of the vertical frame 83. The cylinder is in sliding contact with the left side surface of the vertical frame 83. The vertical frame 83 and the lifting frame 84 are connected for vertical sliding, which enables the lifting frame 84 to move up and down together with the clamping mechanism 7. When the clamping mechanism 7 is at any height, the lifting frame 84 can drive the horizontal movement of the jacking frame 85 without interfering with the normal lifting of the clamping mechanism 7.

[0042] Refer to Figure 8 、 Figure 9 On the upper surface of the moving base 81, a moving groove is formed. The moving groove includes a straight groove 811 and an extension groove 813. The extension groove 813 is located at the left front side of the straight groove 811. The straight groove 811 and the extension groove 813 are connected by an inclined offset groove 812. The extension groove 813 is located at the front side of the moving base 81, and the distance between the extension groove 813 and the cross slide 5 is greater than the distance between the straight groove 811 and the cross slide 5.

[0043] A strip-shaped offset sliding hole 821 is formed through the upper and lower surfaces of the moving slide 82. An offset roller 832 is installed below the offset plate 831. The offset roller 832 passes through the offset sliding hole 821 and rolls in the moving groove. When the cross slide 5 moves the clamping mechanism 7 back and forth, the moving slide 82 can move back and forth together, so that the offset roller 832 moves in the moving groove, and the offset plate 831 moves together. When the offset roller 832 moves from the straight groove 811 to the offset groove 812, the offset roller 832 will drive the offset plate 831 to move a certain distance to the left. When it moves into the extension groove 813, its distance is at the maximum.

[0044] Refer to Figure 7 、 Figure 8 And Figure 10 A sliding hole 852 is formed through the front and back of the jacking frame 85. A through hole 851 is formed through the upper and lower of the jacking frame 85, and the through hole 851 is communicated with the sliding hole 852. The floating member 86 includes a floating plate 861 that is slidably inserted into the sliding hole 852 from left to right. The right end of the floating plate 861 is connected with a floating spring column 863. The right end of the floating spring column 863 slides through the jacking frame 85 and is placed outside it. The floating spring column 863 includes a guide rod that is slidably inserted into the jacking frame 85. One end of the guide rod is fixed to the floating plate 861, and the other end passes through the jacking frame 85 and is outside it. A spring is sleeved on the guide rod, and the two ends of the spring are respectively abutted against the floating plate 861 and the sliding hole 852. The floating spring column 863 makes the floating plate 861 always have a tendency to move to the left, so that the floating plate 861 is at the leftmost end of the sliding hole 852 when it is not affected by external forces other than the floating spring column 863.

[0045] The floating plate 861 is provided with two through holes 862. The upper chuck 75 is formed with a strip-shaped through hole 751 that penetrates up and down. The through hole 751 is directly above the through hole 851 and they have the same size. When the offset roller 832 is in the straight groove 811, the two through holes 862 are directly above the two push rods of the lifting cylinder 76. At this time, when the push rod of the lifting cylinder 76 extends, the push rod can be inserted into the through hole 862 and pass through the through hole 751 above the upper chuck 75, without lifting the upper chuck 75. When the offset roller 832 is in the offset groove 812 and the extension groove 813, the through holes 862 and the two push rods of the lifting cylinder 76 are designed with a dislocation. When the push rod of the lifting cylinder 76 extends, it can contact the floating plate 861, thereby pushing the lifting frame 85 and the upper chuck 75 to move upward together to release the clamping of the magazine 6;

[0046] When the offset roller 832 is in the straight groove 811 and the push rod of the lifting cylinder 76 is inserted into the through hole 862, since the floating plate 861 can move left and right, when the offset roller 832 moves to the offset groove 812 and the extension groove 813, causing the lifting frame 85 to shift to the left, the position of the floating plate 861 will not change, and the floating spring column 863 will be compressed, thus avoiding damage to the push rod of the lifting cylinder 76 being pulled by the left-shifted lifting frame 85 and not affecting the normal movement of the cross slide 5.

[0047] Refer to Figure 5 - Figure 10 As shown in, the alarm mechanism 9 includes an alarm component 92 fixed on the discharge conveyor belt 41. A movable member 91 is installed on the lifting frame 84. The movable member 91 includes a mounting frame 911 fixed on the lifting frame 84. A limiting block 912 is slidably installed back and forth on the inner side of the mounting frame 911 facing inward. A fixing plate is fixed on the mounting frame 911. A reset spring column 915 is slidably installed back and forth on the fixing plate. The front end of the reset spring column 915 is connected to the limiting block 912. A limiting member 93 for limiting the limiting block 912 is installed on the clamping mechanism 7. The reset spring column 915 includes a straight rod slidably inserted into the fixing plate. The front end of the straight rod is fixed to the limiting block 912, and a spring is sleeved on the straight rod. The two ends of the spring are respectively abutted against the fixing plate and the limiting block 912. The limiting block 912 is provided with a strip-shaped opening that penetrates back and forth. A guiding slider is fixed on the mounting frame 911. The guiding slider is slidably placed in the strip-shaped opening, so that the limiting block 912 can move back and forth, and the reset spring column 915 makes the limiting block 912 always have a tendency to move forward.

[0048] The alarm component 92 includes a fixed limit plate 922 fixed on the discharge conveyor belt 41. One end of the fixed limit plate 922 away from the discharge conveyor belt 41 is rotatably installed with a deflection limit plate 923 through a pin. A torsion spring 924 is sleeved on the pin, and the two ends of the torsion spring 924 are respectively connected to the fixed limit plate 922 and the deflection limit plate 923. A buzzer button 925 is fixed at the upper end on the side of the fixed limit plate 922 close to the deflection limit plate 923. The buzzer button 925 is electrically connected to an external buzzer. A contact inclined surface 921 is formed by cutting off a part of the lower side of the deflection limit plate 923 close to the mounting frame 911. An offset inclined surface 914 is formed by cutting off a part of the upper side of the limiting block 912 close to the alarm component 92. And when the clamping mechanism 7 is at the lowest position, the limiting block 912 is below the deflection limit plate 923, and the elastic force of the torsion spring 924 is greater than the elastic force of the reset spring post 915. That is, when the limiting block 912 is not limited, when the limiting block 912 moves upward and contacts the contact inclined surface 921, the deflection limit plate 923 will not deflect upward, and the limiting block 912 will slide backward;

[0049] When the clamping mechanism 7 approaches the discharge conveyor belt 41 and makes part of the magazine 6 on the discharge conveyor belt 41, if the limiting block 912 is limited, the clamping mechanism 7 moves upward, and the offset inclined surface 914 will contact the contact inclined surface 921. At this time, the limiting block 912 cannot retract backward, and the deflection limit plate 923 will deflect upward with the pin as the axis. It will squeeze the buzzer button 925 and turn on the buzzer power supply. The buzzer is a kind of extrusion-triggered buzzer. When the deflection limit plate 923 deflects, it will squeeze the buzzer button 925 to turn on the power supply of the buzzer. At this time, the buzzer will give an alarm, indicating to the nearby personnel that due to insufficient pressure of the lifting cylinder 76 or other reasons, the upper chuck 75 cannot be lifted, and the full magazine 6 in the clamping mechanism 7 cannot pass through the discharge conveyor belt 41 normally and cannot clamp an empty magazine 6 again for chip blanking and collection.

[0050] The limiting member 93 includes a fixed frame 931 fixed above the lower pressing rod 73. A limiting rod 932 is fixed below one side of the fixed frame 931 away from the lower pressing rod 73. A limiting groove 913 is opened above the limiting block 912. When the upper chuck 75 is at the lowest position, the limiting rod 932 is inserted into the limiting groove 913. The cross section of the limiting groove 913 is of a long strip structure and the overall length is relatively long. This enables the limiting rod 932 to always be in the limiting groove 913 when the limiting block 912 moves left and right along with the lifting frame 84. That is, when the upper chuck 75 clamps the magazine 6, the limiting block 912 cannot move back and forth, and thus an alarm can be issued, avoiding the situation that when the magazine 6 full of chips is not placed on the discharge conveyor belt 41, the clamping mechanism 7 carries the magazine 6 and moves upward together, resulting in the full magazine 6 being reset again to participate in the material recovery.

[0051] Working principle: During actual use, after the clamping mechanism 7 grabs an empty magazine 6, the cross slide 5 positions the magazine 6 directly to the right of the transition table 2. The bottom inside of the empty magazine 6 is at the same height as the placement plane of the transition table 2. At this time, the offset roller 832 below the offset plate 831 is within the linear groove 811, and the magazine 6 is in the chip loading position;

[0052] At this time, the two push rods of the lifting cylinder 76 are in the retracted state. The two through holes 862 on the floating plate 861 are directly above the two push rods of the lifting cylinder 76. The upper chuck 75 clamps the magazine 6 under the action of the compression spring 74. During the clamping process, the lower pressing rod 73 is in the downward pressing state under the action of the compression spring 74, and the limiting rod 932 in the limiting member 93 will also descend accordingly, and the limiting rod 932 will also be inserted into the limiting groove 913 of the limiting block 912. At this time, the limiting block 912 cannot move forward or backward;

[0053] After the chip is grabbed onto the transition table 2 by the manipulator after the upper layer of the film is laser cut, the horizontal module 31 moves the lifting member 32 to the left end of the transition table 2. Then, the pusher rod 33 descends under the action of the lifting cylinder and pushes the chip to move rightward and be received into the magazine 6 on the right side. After one chip is placed inside the magazine 6, the cross slide 5 causes the entire clamping mechanism 7 and the magazine 6 to descend by one unit of height. Then, the pusher group 3 again stacks one chip above the chips in the magazine 6. This cycle repeats, causing multiple chips to be stacked in the magazine.

[0054] When the magazine 6 is full of chips, at this time, the magazine 6 and the clamping mechanism 7 are at the lowest position, and the lower outer surface of the magazine 6 is on the same plane as the upper surface of the discharge conveyor belt 41 below;

[0055] After the magazine 6 is full of chips, the cross slide 5 will cause the magazine 6 to move forward together through the clamping mechanism 7. Since the moving slide 82 is fixed to the horizontal slider of the cross slide 5 with screws, the lifting frame 85, the lifting frame 84, and the vertical frame 83 will also move forward together. When the front lower side of the magazine 6 contacts the upper side of the discharge conveyor belt 41, at this time, the offset roller 832 moves into the offset groove 812;

[0056] Since the distance between the offset groove 812 and the cross slide 5 gradually increases from the back to the front, and reaches the maximum at the extension groove 813, when the offset roller 832 moves along the offset groove 812, it will gradually move away from the cross slide 5 and the lifting plate 71. The jacking cylinder 76 is fixed on the lifting plate 71, and the upper chuck 75 is slidably connected to the lifting plate 71 up and down and cannot move left and right. The jacking frame 85 and the floating member 86 are slidably connected to the lower surface of the upper chuck 75 left and right. The jacking frame 85 and the floating member 86 are connected to the offset roller 832 through the lifting frame 84. When the offset roller 832 moves to the left, the jacking frame 85 and the floating member 86 will move to the left together. When the offset roller 832 is at the intersection of the offset groove 812 and the extension groove 813, the position of the through hole 862 on the floating member 86 is misaligned with the two push rods of the jacking cylinder 76 at this time. Then the push rods of the jacking cylinder 76 extend and contact the floating plate 861, thereby pushing the jacking frame 85 and the upper chuck 75 to move upward together, releasing the clamping of the magazine 6. The full magazine 6 will be discharged and removed from the conveyor belt 41. When the upper chuck 75 moves upward, the lower pressing rod 73 rises accordingly and causes the limit rod 932 to rise together. At this time, the limit rod 932 disengages from the limit groove 913 of the limit block 912;

[0057] After that, the cross slide 5 causes the entire clamping mechanism 7 to rise, and the limit block 912 rises together. At this time, the offset inclined surface 914 is directly below the contact inclined surface 921. The offset inclined surface 914 will contact the contact inclined surface 921 and push the limit block 912 to contract backward, so that the clamping mechanism 7 can move upward normally without sounding an alarm. When the bottom end of the lower chuck 77 of the clamping mechanism 7 is flush with the upper conveyor belt 42 above, the cross slide 5 causes the clamping mechanism 7 to move forward a certain distance. At this time, the offset roller 832 moves into the extension groove 813, and the position of the through hole 862 is still misaligned with the two push rods of the jacking cylinder 76, ensuring that the upper chuck 75 is opened. A part of the empty magazine 6 above the upper conveyor belt 42 is placed on the lower chuck 77. The push rods of the jacking cylinder 76 contract, and the upper chuck 75 moves downward under the action of the lower compression spring 74 and clamps the magazine 6 between the upper chuck 75 and the lower chuck 77. The clamping mechanism 7 moves upward again and then moves backward and downward, so that the empty magazine 6 is directly to the right of the transition table 2, and the inner bottom end of the empty magazine 6 is at the same height as the placement plane of the transition table 2. By repeating the above operations, chips can be continuously collected.

[0058] When the jacking cylinder 76 in the clamping mechanism 7 causes the air pressure at the bottom to be greater than the air pressure at the top due to wear or air leakage during the chip collection process, the piston in the jacking cylinder 76 will cause the push rod to extend. Since the offset roller 832 is in the linear groove 811 at this time, the positions of the jacking frame 85 and the floating plate 861 will not shift. The push rod of the jacking cylinder 76 is inserted into the through interface 862 and is above the upper chuck 75 through the through hole 751, and will not jack up the upper chuck 75, thus avoiding the opening of the clamping mechanism 7 caused by the failure of the jacking cylinder 76 and improving safety;

[0059] When the offset roller 832 moves into the offset groove 812 and the extension groove 813, the push rod of the jacking cylinder 76 is still in the through interface 862. Since the jacking cylinder 76 cannot push the upper chuck 75 to move upward, the fully loaded magazine 6 cannot flow out. The pressing rod 73 is also inserted into the limiting groove 913 under the action of the pressing spring 74, and the limiting block 912 cannot slide. The offset inclined surface 914 contacts the contact inclined surface 921. At this time, the limiting block 912 cannot retract backward, and the deflection limiting plate 923 will deflect upward with the axis pin as the axis. When the deflection limiting plate 923 deflects, it will squeeze the buzzer button 925, causing the buzzer to be powered on. At this time, the buzzer will give an alarm, indicating to the nearby personnel that the upper chuck 75 cannot be jacked up due to insufficient pressure of the jacking cylinder 76 or other reasons, and the fully loaded magazine 6 in the clamping mechanism 7 cannot be normally removed through the discharge conveyor belt 41, nor can it clamp and take the empty magazine 6 again for chip blanking and collection. This avoids the situation where when the magazine 6 full of chips is not placed on the discharge conveyor belt 41, the clamping mechanism 7 carries the magazine 6 and moves upward together, resulting in the fully loaded magazine 6 resetting again to participate in the material recovery;

[0060] When the jacking cylinder 76 places the fully loaded magazine 6 or clamps the empty magazine 6, if the jacking cylinder 76 cannot be jacked up due to air pressure or other reasons at this time, the upper chuck 75 cannot move upward either. The upper chuck 75 that cannot move upward causes the pressing rod 73 to be inserted into the limiting groove 913 under the action of the pressing spring 74, and the limiting block 912 cannot slide. The offset inclined surface 914 contacts the contact inclined surface 921. At this time, the limiting block 912 cannot retract backward, and the deflection limiting plate 923 will deflect upward with the axis pin as the axis. The same as above, the buzzer will also give an alarm, indicating to the nearby personnel that the upper chuck 75 cannot be jacked up due to insufficient pressure of the jacking cylinder 76 or other reasons, resulting in the magazine 6 not being able to be discharged or clamped.

[0061] By arranging a clamping mechanism 7 on the cross slide 5, the clamping mechanism 7 uses a downward pressing spring 74 and a downward pressing rod 73 to clamp the magazine 6 with an upper chuck 75, and the lifting of the upper chuck 75 is controlled by the lifting of a lifting cylinder 76, avoiding damage to the magazine 6 caused by excessive clamping force due to a failure of the lifting cylinder 76. Cooperating with the arranged anti-falling mechanism 8, the anti-falling mechanism 8 can translate together with the clamping mechanism 7 and make the lifting of the lifting cylinder 76 ineffective, avoiding the fall of the magazine 6 caused by a failure of the lifting cylinder 76 during the clamping process and improving safety;

[0062] By arranging a floating member 86 in the anti-falling mechanism 8, when the push rod of the lifting cylinder 76 is inserted into the through interface 862, the floating plate 861 can move left and right. Even when the offset roller 832 moves to the offset groove 812 and the extension groove 813, causing the lifting frame 85 to shift to the left, the position of the floating plate 861 will not change, thus avoiding damage to the push rod of the lifting cylinder 76 being pulled by the left-shifted lifting frame 85 and not affecting the normal movement of the cross slide 5;

[0063] By arranging an alarm mechanism 9 on the anti-falling mechanism 8, the alarm mechanism 9 can lift and translate together with the clamping mechanism 7. When the lifting cylinder 76 fails to open the upper chuck 75, the clamping mechanism 7 will give an alarm and rise during the rising process, avoiding the situation that when the magazine 6 full of chips is not placed on the discharge conveyor belt 41, the clamping mechanism 7 carries the magazine 6 and moves up together, resulting in the inability of the full magazine 6 to flow out normally.
