They use a certain process to interconnect the transistors, resistors, capacitors, inductors and other components and wiring required in a circuit, and make them on a small piece or several small pieces of semiconductor wafers or dielectric substrates.

The placement seat 1 can place the integrated circuit, and columns 4 are symmetrically fixed to the front and back left sides of the top of the support plate 2. The columns 4 are located at the front and back sides of the placement seat 1, and a lifting plate 5 is slidably mounted between the front and back columns 4. A reset spring 51 mounted on the column 4 is connected between the front and back sides of the bottom of the lifting plate 5 and the left side of the top of the support plate 2. A bending block 6 is fixedly connected to the middle part of the lifting plate 5. When the bending block 6 moves downward and contacts with the pins of the integrated circuit, the bending block 6 can bend the pins of the integrated circuit. A pressing mechanism 7 is provided on the support plate 2. When the pressing mechanism 7 is operated, the pressing mechanism 7 can drive the bending block 6 to move downward. A positioning mechanism 8 is provided on the placement seat 1. When the positioning mechanism 8 is operated, the positioning mechanism 8 can correct the deviation and position the pins of the integrated circuit.

[0033] The pressing mechanism 7 includes a force bearing rod 71, a mounting frame 72, a hinge rod 73 and an anti-slip grip sleeve 74, see Figure 2 and Figure 3 As shown, a mounting bracket 72 is installed in the middle of the left top of the support plate 2 by welding, and a force-bearing rod 71 is rotatably connected to the top of the mounting bracket 72. An anti-slip grip sleeve 74 is fixedly sleeved circumferentially on the upper part of the force-bearing rod 71. The anti-slip grip sleeve 74 can increase the friction with the hand, and a hinged rod 73 is rotatably connected to the lower part of the force-bearing rod 71. The bottom end of the hinged rod 73 is rotatably connected to the left top of the bending block 6. When the hinged rod 73 moves downward, the hinged rod 73 can drive the lifting plate 5 to move downward.

[0034] The positioning mechanism 8 includes a pressure rod 81, a first spring 82, a limit frame 83, a second spring 84, a positioning rod 85, a contact frame 86 and a third spring 87, see Figure 2 , Figure 4 and Figure 5 As shown, two groups of positioning rods 85 are slidably connected to the left and middle of the top of the placement seat 1, and the number of each group of positioning rods 85 is two. When the positioning rods 85 move inward, the positioning rods 85 can realize the correction and positioning of the pins of the integrated circuit. Two groups of contact frames 86 are slidably connected to the middle and left sides of the placement seat 1. Each group of contact frames 86 corresponds to each group of positioning rods 85. The number of each group of contact frames 86 is two, and each group of inner contact frames 86 is fixedly connected to the lower part of each group of outer positioning rods 85, and each group of outer contact frames 86 is fixedly connected to the lower part of each group of inner positioning rods 85. Each group of two contact frames 86 is staggered, and the upper and lower sides of the contact frames 86 are inclined. The outer sides of each group of two contact frames 86 are aligned with the inner side of the placement seat 1. Two third springs 87 are connected in between, and a limit frame 83 is vertically slidably connected to the left side of the top of the placement seat 1. The left and right sides of the limit frame 83 are respectively in contact with the inclined surfaces of the left and right contact frames 86. When the limit frame 83 moves downward, the limit frame 83 can drive the contact frame 86 to move outward. The front and back sides of the bottom of the limit frame 83 are connected to the inner side of the placement seat 1 with a second spring 84. The lifting plate 5 is symmetrically slidably connected with a pressure rod 81 in the front and back directions. The pressure rod 81 corresponds to the limit frame 83. When the pressure rod 81 moves downward and contacts the limit frame 83, the pressure rod 81 can drive the limit frame 83 to move downward. The upper parts of the front and back pressure rods 81 are connected to the top of the lifting plate 5 with a first spring 82.

[0035] First, two integrated circuits are placed on the placement seat 1, and the pins of the integrated circuits are between the corresponding two positioning rods 85, and then the anti-slip grip sleeve 74 is held to drive the force-bearing rod 71 to move downward. Due to the effect of the anti-slip grip sleeve 74, the friction with the hand can be increased, and the force-bearing rod 71 is pulled downward more firmly. The downward movement of the force-bearing rod 71 drives the hinged rod 73 to move downward, and the downward movement of the hinged rod 73 drives the bending block 6 to move downward. The downward movement of the bending block 6 drives the lifting plate 5 to move downward, and the reset spring 51 is compressed. The lifting plate 5 moves downward and is driven by the first spring 82 The pressure rod 81 moves downward, and when the pressure rod 81 moves downward and contacts the limit frame 83, the pressure rod 81 drives the limit frame 83 to move downward, the second spring 84 is compressed, and the limit frame 83 moves downward to drive each group of two contact frames 86 to move outward, and the third spring 87 is compressed. Since each group of two contact frames 86 is staggered, each group of two contact frames 86 moves outward to drive each group of two positioning rods 85 to move inward, and each group of two positioning rods 85 moves inward to contact the pins of the integrated circuit, and the positioning rods 85 correct the deviation of the pins of the integrated circuit. When the limit frame 83 moves downward, When the maximum stroke is reached, the limit frame 83 stops moving downward, and the limit frame 83 stops driving the positioning rod 85 to move inward through the contact frame 86. The limit frame 83 causes the pressure rod 81 to stop moving downward, and the lifting plate 5 continues to move downward to stretch the first spring 82. At this time, the bending block 6 contacts the integrated circuit pin after the deviation correction and positioning, and the bending block 6 bends the pin of the integrated circuit. After the pin of the integrated circuit is bent, the force-bearing rod 71 is released. Due to the action of the reset spring 51, the lifting plate 5 moves upward to reset and drives the bending block 6 to move upward to reset. The bending block 6 is reset through the hinge rod 73. The dynamic force rod 71 moves upward to reset, and the lifting plate 5 moves upward to reset so that the first spring 82 contracts and resets, and then the lifting plate 5 drives the pressure rod 81 upward to reset through the first spring 82, and the pressure rod 81 resets and disengages from the limit frame 83. Due to the action of the second spring 84, the limit frame 83 moves upward to reset without limiting the contact frame 86. Due to the action of the third spring 87, the contact frame 86 moves inward to drive the positioning rod 85 to move outward to reset, and the positioning rod 85 resets and disengages from the pins of the integrated circuit, and then the integrated circuit with the bent pins is removed from the placement seat 1. In this way, the positioning rod 85 can correct the deviation and position the pins of the integrated circuit before bending, thereby improving the accuracy of the bending. Example 2

[0036] On the basis of embodiment 1, a fixing mechanism 9 is also included, and the fixing mechanism 9 includes a fixing frame 91, a trigger frame 92, a fixing seat 93, a fourth spring 94, a slot block 95, a fifth spring 96, a sixth spring 97 and a guide rod 98, see Figure 6-Figure 8As shown, two guide rods 98 are symmetrically fixed to the front and back right sides of the placement seat 1, and a fixing seat 93 is slidably mounted on the four guide rods 98. The inner side of the fixing seat 93 is arc-shaped, and a fourth spring 94 mounted on the guide rod 98 is connected between the bottom of the fixing seat 93 and the inner side of the placement seat 1. A fixing frame 91 is rotatably connected between the inner ends of the two fixing seats 93 on the front side and between the inner ends of the two fixing seats 93 on the rear side. When the fixing frame 91 swings downward and contacts the integrated circuit, the fixing frame 91 can press and fix the integrated circuit. A slot block 95 is symmetrically fixed to the lower rear side of the fixing frames 91 on the front and rear sides. The slot block 95 is tilted, and the four slot blocks 95 are respectively The sliding sleeve is mounted on the inner side of the four fixed seats 93, and the bottom of the four slotted blocks 95 are respectively connected to the lower part of the four fixed seats 93 with a fifth spring 96, and the elastic coefficient of the fifth spring 96 is smaller than the elastic coefficient of the fourth spring 94. The trigger frame 92 is symmetrically slidably connected to the front and rear right side of the placement seat 1, and the right side of the trigger frame 92 is slidably connected to the slotted block 95. When the trigger frame 92 moves, the trigger frame 92 can drive the slotted block 95 to swing, and the left ends of the trigger frames 92 on the front and rear sides are respectively slidably connected to the front and rear sides of the limit frame 83, and two sixth springs 97 are respectively connected between the left sides of the top of the trigger frames 92 on the front and rear sides and the front and rear sides of the top of the limit frame 83.

[0037] The stripping mechanism 10 is also included. The stripping mechanism 10 includes a magnetic track 101, a stripping frame 102, a seventh spring 103, a stripping plate 104 and a magnetic block 105. Figure 6 , Fig. 9 and Fig.10 As shown, a stripping rack 102 is symmetrically slidably connected between the bending block 6 and the lifting plate 5, and the outer sides of the front and rear stripping racks 102 respectively slide through the front and rear columns 4 on both sides, and the middle parts of the outer sides of the front and rear stripping racks 102 are fixedly connected with magnetic blocks 105, and the magnetic blocks 105 are located in the columns 4. A stripping plate 104 is installed between the bottom ends of the front and rear stripping racks 102 by welding. When the stripping plate 104 contacts the pins of the integrated circuit, the stripping plate 104 can limit the pins of the integrated circuit to complete the stripping, and a seventh spring 103 is connected between the inner side of the bending block 6 and the lower part of the front and rear stripping racks 102, and the lower parts of the inner sides of the front and rear columns 4 are symmetrically fixedly connected with magnetic rails 101, and when the magnetic block 105 contacts the magnetic rails 101, the magnetic rails 101 can absorb the magnetic block 105.

[0038] When the pressure rod 81 drives the limit frame 83 to move downward, the limit frame 83 moves downward and drives the trigger frame 92 to move downward through the sixth spring 97. Since the elastic coefficient of the fifth spring 96 is smaller than the elastic coefficient of the fourth spring 94, the trigger frame 92 moves downward and first drives the slot block 95 to swing downward. The fifth spring 96 is compressed, and the slot block 95 swings downward to drive the fixing frame 91 to swing downward. When the fixing frame 91 swings downward and is in a horizontal state, the slot block 95 also swings downward to the maximum stroke, and the slot block 95 stops driving the fixing frame 91 to swing downward, and then the trigger frame 92 continues to move. The downward movement drives the slot block 95 to move downward, the slot block 95 moves downward and drives the fixing frame 91 to move downward, the fixing frame 91 moves downward and drives the fixing seat 93 to move downward, the fourth spring 94 is compressed, the fixing frame 91 moves downward and contacts the integrated circuit, the fixing frame 91 presses and fixes the integrated circuit, the fixing frame 91 stops moving downward, the fixing seat 93 and the slot block 95 stop moving downward, the trigger frame 92 also stops moving downward, the limit frame 83 continues to move downward to the maximum stroke to compress the sixth spring 97, and then the bending block 6 bends the pins of the integrated circuit again. When the pin of the integrated circuit is bent, the pressure rod 81 moves upward and resets, so that the sixth spring 97 is stretched and reset, and then the pressure rod 81 drives the trigger frame 92 to move upward and reset through the sixth spring 97. At the same time, due to the action of the fourth spring 94, the fixing seat 93 moves upward and resets, driving the fixing frame 91 to move upward and reset. The fixing frame 91 moves upward and resets to break contact with the integrated circuit, and the fixing frame 91 moves upward and resets to drive the slot block 95 to move upward and reset. The slot block 95 moves upward and resets synchronously with the trigger frame 92. After the slot block 95 moves upward and resets, the trigger frame 92 continues to move upward and resets to drive the slot block 95 to swing upward and reset. The slot block 95 swings upward and resets to drive the fixing frame 91 to swing upward and reset. In this way, the phenomenon of the integrated circuit being lifted up during the bending process can be prevented from affecting the bending, thereby improving the stability of the bending of the pin of the integrated circuit.

[0039] When the lifting plate 5 moves downward and drives the bending block 6 to move downward, the bending block 6 moves downward and drives the stripping frame 102 to move downward through the seventh spring 103, and the stripping frame 102 moves downward and drives the stripping plate 104 to move downward, and the stripping frame 102 moves downward and also drives the magnetic block 105 to move downward, the magnetic block 105 moves downward and contacts the magnetic track 101, the magnetic track 101 and the magnetic block 105 are in magnetic contact, the magnetic block 105 slides in the magnetic track 101, and when the bending block 6 contacts and bends the pins of the integrated circuit, the stripping plate 104 also contacts the pins of the integrated circuit, and when the pins of the integrated circuit are bent, the lifting plate 5 moves upward and drives the bending block 6 to move upward, and due to the magnetic contact between the magnetic block 105 and the magnetic track 101, the stripping frame 1 02 and the stripping plate 104 stop moving upward first, the stripping plate 104 limits the pins of the integrated circuit, and then the bending block 6 continues to move upward to disengage from the pins of the integrated circuit, and the bending block 6 moves upward to compress the seventh spring 103. When the seventh spring 103 is compressed to the maximum stroke, the bending block 6 drives the stripping frame 102 to move upward and reset through the seventh spring 103, and the stripping frame 102 resets and drives the stripping plate 104 to move upward and disengage from the pins of the integrated circuit, and the stripping frame 102 resets and drives the magnetic block 105 to move upward and reset. When the magnetic block 105 resets and disengages from the magnetic track 101, due to the action of the seventh spring 103, the stripping frame 102 moves upward to a suitable position and drives the stripping plate 104 to move upward into the bending block 6. In this way, the pins of the integrated circuit can be prevented from moving upward with the bending block 6, causing tilting and affecting subsequent use, thereby ensuring the normal use of the integrated circuit pins after bending. Example 3

[0040] On the basis of the embodiment 1 and the embodiment 2, a buffer rod 11 and an eighth spring 12 are also included. Fig.11 As shown, a buffer rod 11 is symmetrically and slidingly connected between the bending block 6 and the lifting plate 5. The buffer rod 11 is located between the front and rear stripping frames 102. The bottom end of the buffer rod 11 contacts the top of the stripping plate 104. When the stripping plate 104 is reset, the buffer rod 11 can buffer the reset of the stripping plate 104. The upper parts of the front and rear buffer rods 11 and the top of the lifting plate 5 are connected with an eighth spring 12.

[0041] Also includes a storage frame 13, see Fig.11 As shown, a material storage frame 13 is embedded and slidably connected to the lower right side of the placement seat 1, and the material storage frame 13 can be used to place parts.

[0042] When the stripper plate 104 moves upward to reset, the stripper plate 104 resets and contacts the buffer rod 11. Due to the action of the eighth spring 12, the buffer rod 11 buffers the reset of the stripper plate 104. In this way, the stripper plate 104 can be prevented from violently resetting and contacting the bending block 6 to cause deformation, thereby ensuring the safety of the bending block 6.

[0043] When parts need to be placed, the material storage frame 13 can be pulled to move to the right to a suitable position, and then the parts are placed in the material storage frame 13, and then the material storage frame 13 is pushed to move to the left to reset. In this way, the storage and use of parts are more convenient.
