DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with specific drawings.

[0025] like Figure 1As shown, the present invention provides a rib cutting device for multiple types of integrated circuits, including a frame 100, a driving mechanism 120 arranged on the frame 100, a punching head 200 arranged in the frame 100 and connected to the driving mechanism 120, a first upper cutter 230 and a second upper cutter 240 respectively arranged at two ends of the punching head 200 and arranged opposite to each other, and a rib cutting table 300 arranged below the punching head 200 and connected to the frame 100. The output end of the driving mechanism 120 is connected to the punching head 200 through the connecting rod by the bolt 900. The driving mechanism 120 drives the punching head 200 to move back and forth in the direction of approaching or moving away from the rib cutting platform 300. The first lower knife group 400 that cooperates with the first upper cutter 230 to punch the pins of the flat package integrated circuit is screwed to the corresponding position of the rib cutting platform 300 by the bolt 900. The second lower knife group 600 that cooperates with the second upper cutter 240 to punch the pins of the dual in-line integrated circuit is screwed to the corresponding position of the rib cutting platform 300 by the bolt 900. At one end of the rib cutting platform 300, the first upper cutter 230 and the first lower knife group 400 can cooperate with each other to complete the pin punching work of the flat package circuit 500. If it is necessary to cut the ribs for the dual in-line integrated circuit, at the other working end of the rib cutting platform 300, the second upper cutter 240 and the second lower knife group 600 can cooperate with each other to complete the double in-line pin punching work. A variety of integrated circuits can be processed on one device, saving floor space. When punching different types of integrated circuit pins, there is no need to assemble or disassemble components, and there is no need to equip separate machines, saving manufacturing costs in production. In addition, for dual in-line integrated circuits, one punching action can complete the rib cutting of the upper and lower pins at the same time, with high processing accuracy.

[0026] A material collecting notch 140 is provided on the bottom surface of the frame 100 at the positions corresponding to the two punching working ends of the rib cutting table 300. Waste materials after the integrated circuit rib cutting falls from the material collecting notch 140, and a material box 130 with a receiving opening facing the rib cutting table 300 and used for collecting waste materials is inserted into the material collecting notch 140. The material box 130 is distributed below the rib cutting table 300 and arranged along the width direction of the frame 100.

[0027] The driving mechanism 120 may be a reciprocating cylinder capable of driving the punching head 200 to reciprocate, and compressed air is used for punching. An electric control box 110 is provided at the top of the frame 100 and is electrically connected to the driving mechanism 120 , so as to control the start or shut down of the driving mechanism 120 .

[0028] The punching head 200 includes an upper template 210 that is screwed to the driving mechanism 120 and has an upper limit groove, and an upper knife seat 220 that is detachably connected to the upper limit groove. The upper limit groove is a groove arranged along the width direction of the upper template 210 and is through at both ends and concave toward the driving mechanism 120. Fig.10As shown, the upper knife seat 220 is provided with two upper knife seat connection holes 221 arranged at intervals. The upper knife seat connection holes 221 are long holes. The upper knife seat 220 is connected to the upper limit slot through bolts 900 in the long holes. The first upper cutter 230 and the second upper cutter 240 are respectively connected to the end faces of the upper knife seat 220 in the width direction. The upper limit slot plays a limiting role in the process of installing the upper knife seat 220, limiting the upper knife seat 220 to move and adjust the position only in the width direction of the upper template 210, but not in the length direction of the upper template 210. It is adapted to the punching surface of the rib cutting table 300 to avoid punching distortion.

[0029] The rib cutting table 300 includes a lower template 310 bolted to the frame 100 and having a lower limit groove, and a lower knife seat 320 detachably connected to the lower limit groove. The lower template 310 is provided with a guide column 330 that is sleeved with the guide hole at the corresponding position of the upper template 210. The guide column 330 guides the reciprocating punching head 200, and the punching is more accurate. The lower limit groove is a groove arranged along the width direction of the lower template 310 and penetrated at both ends and concave in the direction close to the frame 100. In addition, the lower knife seat 320 is also provided with two spaced long holes, which are installed in the long holes by bolts 900 to connect the lower knife seat 320 with the lower limit groove. The function of the lower limit groove is the same as that of the upper limit groove. In this way, the lower knife seat 320, which can be adjusted in the width direction of the lower template 310, can cooperate with the two upper cutters on the upper knife seat 220. A cover plate 323 is screwed to the top surface of the lower knife seat 320 to close the two long holes with bolts 900 installed, so as to prevent the lead waste from leaking into the gap, thereby affecting the mutual cooperation between the punching head 200 and the rib cutting table 300.

[0030] like Figure 6 and Figure 7 As shown, the first end of the lower knife seat 320 is provided with a first punching cavity 321 for the first upper cutter 230 to move up and down to punch the pin, and the second end is provided with a second punching cavity 322 for the second upper cutter 240 to move up and down to punch the pin, and the first punching cavity 321 and the second punching cavity 322 are arranged at intervals along the width direction of the lower knife seat 320. It is equivalent to that the two opposite end surfaces of the rib cutting table 300 can perform the punching pin operation respectively, so that the position distribution is reasonable and convenient, and it is convenient to adjust the tool for different processing objects.

[0031] The first lower knife group 400 includes a first lower cutter 410 screwed to the first end of the lower knife seat 320 by a bolt 900 and a plurality of first adjustment plates 420 detachably connected to one side of the first lower cutter 410. A fixing screw hole 422 is provided on the first adjustment plate 420. The first adjustment plate 420 is connected to the first lower cutter 410 by a bolt screwed into the fixing screw hole 422. One of the plurality of first adjustment plates 420 is selectively installed on the side wall of the first lower cutter 410 away from the first end. The first adjustment plate 420 has a cutting rib fixing groove 421 which is recessed toward the lower knife seat 320. A placement and fixing through cavity 4213 is provided in the cutting rib fixing groove 421 for the pins of the flat package circuit 500 to pass through. After the pins of the flat package circuit 500 pass through the placement and fixing through cavity 4213, the circuit pins to be punched are placed in the first punching cavity 321 and are located between the first upper cutter 230 and the first lower cutter 410. The first upper cutter 230 is pressed downward to complete the rib cutting operation of the flat package circuit 500.

[0032] like Fig. 9 As shown, the rib cutting fixing groove 421 includes a first plane 4210, vertical planes 4211 respectively distributed on both sides of the first plane 4210, a second plane 4212 arranged between the two vertical planes 4211 and perpendicular to the first plane 4210, and a placement fixing cavity 4213 distributed at the connection between the first plane 4210 and the second plane 4212. The distance between the second plane 4212 and the first plane 4210 is an adjustment part, and the adjustment parts of several first adjustment plates 420 are structures with a constant gradient and gradually increase. The size of the adjustment part is between 1.5mm and 6.2mm, and the adjustment part of each first adjustment plate 420 gradually increases with a gradient of 0.1mm. Figure 8 As shown, when the flat package integrated circuit is cut, after the circuit pin extends from the through placement and fixing cavity 4213 into the first punching cavity 321, the larger the spacing between the first plane 4210 and the second plane 4212, the shorter the length of the pin to be cut at the punching end will be, because the integrated circuit needs to be tightly against the first plane 4210 to fix the integrated circuit. Conversely, the longer the length of the pin to be punched will be. By replacing the first adjustment plate 420 of different sizes, the size of the adjustment part can be adjusted, so that circuit pins of different lengths can be punched out according to actual processing needs.

[0033] A protection plate 423 located on one side of the first adjustment plate 420 is also screwed with bolts 900, and an operation notch 4230 is provided on the protection plate 423 to expose the cutting rib fixing groove 421. A first side protection plate 424 screwed with the lower template 310 is provided on both sides of the protection plate 423, and the punching working end is separated by the protection plate 423 and the first side protection plate 424 to prevent the processing personnel from accidentally touching and causing personal injury.

[0034] like Figure 4and Figure 5 As shown, the second lower cutter assembly 600 includes a second lower cutter 610 screwed to the second end of the lower cutter seat 320 by a bolt 900, an adjustment mechanism 620 detachably connected to one side of the second lower cutter 610, and a third lower cutter 630 detachably connected to one side of the second lower cutter 610 and located below the adjustment mechanism 620. A first placement cavity 62120 for one column of pins of the dual in-line plug-in circuit 700 to pass through is formed between the second lower cutter 610 and the adjustment mechanism 620, and a second placement cavity 633 for another column of pins of the dual in-line plug-in circuit 700 to pass through is formed between the adjustment mechanism 620 and the third lower cutter 630. After the two columns of pins pass through the first placement cavity 62120 and the second placement cavity 633 respectively, the two columns of pins to be punched are placed in the second punching cavity 322, so that the second upper cutter 240 moves back and forth in the second punching cavity 322 to perform the rib cutting operation. The second upper cutter 240 punches downwards, and can directly cut off two rows of pins at the same time, and the processing accuracy is higher than the accuracy of punching each row separately. The lower template 310 is also connected to two second side protection plates 800 located on both sides of the second lower cutter group 600 by bolts 900, which also prevents the processing personnel from accidentally touching and causing processing accidents.

[0035] A recessed notch 611 is provided along the width direction of the second lower cutter 610, and the recessed notch 611 vertically penetrates the second lower cutter 610. A first connecting portion 612 is provided on both sides of the recessed notch 611, and the adjustment mechanism 620 is screwed to the two first connecting portions 612 by bolts 900. The adjustment mechanism 620 includes an adjustment main plate 621 screwed to the first connecting portions 612 by bolts 900, at least two adjustment installation slots 6210 provided on the adjustment main plate 621, and a plurality of second adjustment plates 622 detachably connected to the adjustment installation slots 6210. The adjustment main board 621 includes a first vertical plate 621a which is screwed to the first connection part 612 by bolts 900 and is located on one side of the first connection part 612, a horizontal plate 621b fixed to the top of the first vertical plate 621a, and a second vertical plate 621c connected perpendicularly to the horizontal plate 621b. The horizontal plate 621b is perpendicularly connected to the end face of the first vertical plate 621a close to the second lower cutter 610. The lower end face of the horizontal plate 621b is an auxiliary connection part 6211, and the auxiliary connection part 6211 abuts against the punching surface of the second lower cutter 610. Two adjustment installation grooves 6210 are vertically distributed on the top face of the horizontal plate 621b and are recessed toward the side away from the second lower cutter 610. A pin placement groove 6212 located below the recessed notch 611 is provided on the side of the adjustment main board 621 away from the second lower cutter 610, and the first placement cavity 62120 is distributed in the pin placement groove 6212. The first placement cavity 62120 vertically passes through the pin placement slot 6212, and the bottom surface of the first placement cavity 62120 is flush with the punching surface of the second lower cutter 610. After the upper pins of the dual in-line integrated circuit are inserted into the first placement cavity 62120, the pins to be punched are placed on the punching surface of the second lower cutter 610.

[0036] A second connection part 613 is provided below the first connection part 612, and the third lower cutter 630 includes a cutter body 631 detachably connected to the second connection part 613 and a cutter body 632 fixedly provided above the cutter body 631 and adapted to the recessed notch 611. A connecting screw hole 6130 and a plurality of positioning pin holes 6131 are provided on the second connection part 613, and a plurality of positioning pin holes 6131 are also provided at corresponding positions of the cutter body 631. The cutter body 631 and the second connection part 613 are first positioned by inserting the positioning pins 6132 into the positioning pin holes 6131, and then the body and the second connection part 613 are screwed together by screwing the bolts 900 into the connecting screw holes 6130. The gap between the cutter body 632 and the recessed notch 611 after being connected and fixed is the second placement cavity 633, and when the pins of the dual in-line circuit 700 extend into the first placement cavity 62120 and the second placement cavity 633 respectively, the lengths of the two rows of circuit pins to be punched are equal. The portion between the recessed notch 611 and the pin placement groove 6212 is simply between two rows of pins, and the knife body 632 provides stable support below the following pins. The knife body 632 is a tool that cooperates with the second upper cutter 240. When the second upper cutter 240 punches downward, the rib cutting operation of the two rows of pins can be completed simultaneously, which saves processing steps, improves processing accuracy, and helps to improve work efficiency.

[0037] A plurality of second adjustment plates 622 are selectively installed in the adjustment installation slot 6210. The second adjustment plate 622 includes two spaced adjustment legs 6220, an adjustment crossbar 6221 fixed between the two adjustment legs 6220, and an adjustment wing 6222 fixed to one side of the adjustment legs 6220. The adjustment wing 6222 is fixed to the side of the adjustment legs 6220 away from the second lower cutter 610. Holding the adjustment wing 6222 facilitates the extraction of the second adjustment plate 622. Figure 2 As shown, two adjustment legs 6220 pass through the adjustment mounting groove 6210 and are distributed between the second lower cutter 610 and the adjustment main board 621. The thickness of the adjustment legs 6220 in the plurality of second adjustment plates 622 is a structure that gradually increases in equal gradients, and the contact distance of the auxiliary connection part 6211 on the punching surface of the second lower cutter 610 is controlled by the thickness of the adjustment legs 6220. The thickness of the adjustment legs 6220 is between 3 mm and 6 mm, and the thickness of the adjustment legs 6220 of each second adjustment plate 622 gradually increases in a gradient of 0.1 mm. When processing dual in-line integrated circuits, after the upper row extends into the first placement cavity 62120 and the lower row extends into the second placement cavity 633, the contact distance between the auxiliary connection part 6211 and the punching surface of the second lower cutter 610, that is, the overlapping distance, is adjusted by the thickness of the adjustment legs 6220 in different second adjustment plates 622, as shown in FIG. Figure 3As shown, when the thickness is greater, the contact overlap distance is shorter, which is equivalent to moving the adjustment main board 621 away from the second cutter, then the length of the pin to be punched is shorter, and vice versa, when the thickness is smaller, the length of the pin to be punched is longer, so that the required pin length can be adjusted according to the processing requirements. For such a second adjustment plate 622, as long as the bolt 900 at the second connecting portion 613 is loosened, the adjustment leg 6220 can be pulled out from the adjustment mounting groove 6210 for replacement, and then locked by the bolt 900 to replace it with the second adjustment plate 622 of the required size. Only four steps are required: loosen the bolt 900, pull out the second adjustment plate 622, replace the second adjustment plate 622 of the required size, and then tighten the bolt 900. The entire adjustment process is simple and easy to operate, with simple steps, which reduces the difficulty of adjustment. Production line processing personnel of any technical level can process integrated circuits with the required pin length.

[0038] In addition, two adjustment installation grooves 6210 are respectively distributed on both sides of the first placement cavity 62120, and two adjustment legs 6220 are inserted into the adjustment installation grooves 6210 to adjust the length of the pin to be punched. The purpose of size adjustment is achieved directly by adjusting the thickness of the legs 6220, which is equivalent to the size adjustment of the rulers on both sides of the punching position being completed synchronously and kept consistent. The overlap distance can be adjusted in one step and then locked with bolts 900. The advantage of such adjustment is that the synchronization of adjusting the required overlap distance is higher. By directly replacing different second adjustment plates 622, the length of the pins to be punched in the upper and lower rows can be adjusted synchronously. The required overlap distance can be adjusted without the help of other tools, which helps to improve the processing accuracy.

[0039] The present rib cutting equipment: First, the rib cutting table 300 and the punching head 200 both have two punching ends, which correspond to each other, so as to achieve the purpose of punching different types of integrated circuits, and the use is more diversified, and at the same time, the purpose of saving equipment and space is achieved. For different punching objects, the required size of the pin length can be adjusted. Second, the second lower knife group 600 cooperates with the second upper cutter 240 to directly punch the double-row pins in one punching action, so that the length of the double-row pins can be kept consistent, which helps to improve the processing accuracy. Third, when adjusting the length of the pin to be punched for the dual-row in-line integrated circuit, the thickness of the support leg 6220 is adjusted by the second adjustment plate 622 to adjust the overlapping distance between the auxiliary connection part 6211 and the punching surface of the second lower cutter 610. Only by replacing such a second adjustment plate 622, not only the length of the upper and lower row pins can be adjusted synchronously, but also the size adjustment on both sides of the pin placement groove 6212 can be kept consistent synchronously, and the accuracy of the adjustment precision is higher, avoiding the adjustment of skew and distortion. The third lower cutter 630 below plays a supporting and reinforcing role. By simply replacing the second adjustment plate 622, the required length of the pin to be punched can be obtained, thereby enhancing the ability to adjust synchronization and achieving the adjustment purpose without the aid of any distance measuring tools.

[0040] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
