Description

Technical Field

[0001] The present invention relates to the field of semiconductor devices, and in particular to an automatic pin insertion machine device for an IGBT module. Background Art

[0002] IGBT, or insulated gate bipolar transistor, is a semiconductor device that is widely used in rail transit, smart grid, aerospace, electric vehicles, new energy equipment and other fields. For example, the Chinese patent with publication number: CN117810137B discloses an automatic pin insertion machine for an IGBT module, which changes the position of the adjustment block by rotating the crosshead screw to move the adjustment block, and starts the adjustment motor to move the adjustment plate to the other side of the needle removal device housing, thereby avoiding the situation where the pin positions are not on the same horizontal line, affecting the pin insertion efficiency of the IGBT module.

[0003] However, the intervals between the multiple adjustment plates are fixed, and the spacing between the needles inserted into the IGBT module is usually small, so when clamping the needles with small spacing, the adjustment plates cannot insert the needles into the IGBT module at the same time, which has great limitations. Summary of the invention

[0004] In order to overcome the disadvantage that the existing pin insertion equipment has great limitations in that the adjustment plate cannot insert multiple pin bodies into the IGBT module at the same time when clamping the pins with small pitch, the present invention provides an automatic pin insertion machine for IGBT modules.

[0005] The technical solution of the present invention is: an automatic pin insertion machine device for IGBT modules, including a body; also including a connecting frame, an electric turntable, a rectangular plate, a fixed plate, a clamping assembly and an adjusting assembly; the body is connected to the connecting frame; the connecting frame is connected to the adjusting assembly; the moving part of the adjusting assembly is connected to several electric turntables, and the adjusting assembly is used to adjust the distance between the several electric turntables; each electric turntable is connected to a rectangular plate, and the rectangular plate is set at an inclined angle of forty-five degrees; each rectangular plate is connected to a fixed plate; each fixed plate is connected to a clamping assembly for clamping the needle body.

[0006] Furthermore, the clamping assembly includes an electric push rod I, a clamping cylinder and a clamping plate; each fixed plate is connected to two electric push rods I; the telescopic end of each electric push rod I located on the same fixed plate is connected to a clamping cylinder, and the clamping cylinder is slidably connected to the corresponding fixed plate; each clamping cylinder is connected to a clamping plate.

[0007] Furthermore, the clamping tube and the clamping plate are both made of alloy material.

[0008] Furthermore, the adjustment component includes an electric slide rail, a slider, a mounting block, a slide plate, a screw and a motor; a connecting frame is fixedly connected to a plurality of electric slide rails; each electric slide rail is slidably connected to a plurality of block groups; each block group is composed of two sliders; a slider on the same block group is fixedly connected to a mounting block, and the mounting block is connected to the corresponding electric turntable; two sliders on the same block group are commonly fixedly connected to a slide plate, and the slide plate is slidably connected to the corresponding mounting block; two sliders on the same block group are commonly rotatably connected to a screw, and the screw is slidably connected to the corresponding mounting block; a slider on the same block group is fixedly connected to a motor, and the output shaft of the motor is fixedly connected to the corresponding screw.

[0009] Furthermore, the clamping tube is arranged in a conical shape.

[0010] Furthermore, the clamping cylinder and the telescopic end of the electric push rod I are detachably connected.

[0011] Furthermore, it also includes an electric push rod II and a connecting pipe; each fixed plate is composed of a connecting plate I and a connecting plate II that are slidably connected to each other; one electric push rod I is fixed to the connecting plate I, and the other electric push rod I is fixed to the connecting plate II; each electric turntable is fixed with an electric push rod II, and the telescopic end of the electric push rod II is fixed to the corresponding connecting plate II, and the connecting plate II is fixed to the rectangular plate; the clamping plate is hollow, and each clamping plate located on the corresponding connecting plate I is provided with a plurality of circular holes on its inner side; each clamping plate located on the corresponding connecting plate I is connected to a connecting pipe.

[0012] Furthermore, a rubber strip is provided on the inner edge of the clamping plate.

[0013] Furthermore, it also includes a spring rod II, a cone sleeve, an electric push rod III and a pressure plate; a plurality of spring rods II are fixedly connected in the clamping cylinder on each connecting plate I; the telescopic ends of all spring rods II located on the same clamping cylinder are fixedly connected to a cone sleeve; an electric push rod III is fixedly connected in the clamping cylinder on each connecting plate I; and a pressure plate is fixedly connected to the telescopic end of each electric push rod III.

[0014] Furthermore, a distance sensor is also included; each connecting plate II and each connecting plate I is fixedly connected with a distance sensor.

[0015] The beneficial effect is as follows: the present invention sets the rectangular plate at a forty-five-degree inclination angle. Compared with the horizontal rectangular plate, when the inclined rectangular plate drives the clamping tube and the clamping plate to move downward, the distance between the rectangular plate and the surrounding inserted needle bodies is larger, so it is not easy to collide with the inserted needle bodies and cause damage to the inserted needle bodies, and it is suitable for inserting needles with small spacing.

[0016] The present invention controls the start of the external pump, and sucks the clamping plate through the connecting pipe located on the connecting plate I, so that the corresponding clamping plate vacuum adsorbs the needle body through the circular hole, and adsorbs the needle body on the inner side of the clamping plate located on the connecting plate I. Then, in the process that the cylinder drives the connecting frame to drive the clamping tube and the clamping plate to insert the needle body into the IGBT module body, the electric push rod II is controlled to make the connecting plate II drive the corresponding clamping tube and the clamping plate to move upward, so that only one clamping plate adsorbs the needle body and then inserts it downward into the IGBT module body, further reducing the volume of the clamping tube and the clamping plate to insert the needle body into the IGBT module body, and adapting to the pin spacing with smaller spacing.

[0017] The present invention detects the distance between the corresponding clamping cylinder and clamping plate and the IGBT module body through a distance sensor, and then detects whether the depth of all needle bodies inserted into the IGBT module body is consistent. When clamping the insertion pin of the shorter needle body, the electric push rod III is controlled to drive the pressure plate to move downward, so that the pressure plate is against the upper end of the shorter needle body, thereby improving the insertion effect.

[0025] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] An automatic pin insertion machine device for IGBT modules, such as Figure 1-Figure 6 As shown, including organisms;

[0028] It also includes a connecting frame 101, an electric turntable 102, a rectangular plate 103, a fixed plate 104, a clamping assembly and an adjusting assembly; the machine body is connected to the connecting frame 101; the connecting frame 101 is connected to the adjusting assembly; the moving part of the adjusting assembly is connected to a plurality of electric turntables 102, and the adjusting assembly is used to adjust the distance between the plurality of electric turntables 102; each electric turntable 102 is respectively connected to a rectangular plate 103, and the rectangular plate 103 is arranged at an inclined angle of forty-five degrees; each rectangular plate 103 is respectively connected to a fixed plate 104; each fixed plate 104 is respectively connected to a clamping assembly for clamping the needle body 8.

[0029] The machine body includes a cabinet 1, a feeder 2, a clamp 3, an electric guide rail 4, a moving block 5 and a cylinder 6; the cabinet 1 is fixedly connected to the feeder 2 for conveying the needle body 8; the cabinet 1 is fixedly connected to the clamp 3 for clamping the IGBT module body 7; the cabinet 1 is bolted to the electric guide rail 4; the electric guide rail 4 is slidably connected to the moving block 5; the moving block 5 is fixedly connected to the cylinder 6, and the telescopic end of the cylinder 6 is fixedly connected to the connecting frame 101.

[0030] The clamping assembly includes an electric push rod Ⅰ105, a clamping cylinder 106 and a clamping plate 107; each fixed plate 104 is connected to two electric push rods Ⅰ105; the telescopic end of each electric push rod Ⅰ105 located on the same fixed plate 104 is connected to one-half of the clamping cylinder 106, and the clamping cylinder 106 is slidably connected to the corresponding fixed plate 104; each clamping cylinder 106 is connected to one-half of the clamping plate 107.

[0031] The clamping tube 106 and the clamping plate 107 are both made of alloy material, which ensures the strength and service life of the clamping tube 106 and the clamping plate 107 .

[0032] The adjustment component includes an electric slide rail 108, a slider 109, a mounting block 1010, a slide plate 1011, a screw rod 1012 and a motor 1013; the connecting frame 101 is bolted to two electric slide rails 108; each electric slide rail 108 is slidably connected to a number of block groups; each block group is composed of two sliders 109; a slider 109 on the same block group is fixedly connected to a mounting block 1010, and the mounting block 1010 is connected to the corresponding electric turntable 102; two sliders 109 on the same block group are commonly fixedly connected to a slide plate 1011, and the slide plate 1011 is slidably connected to the corresponding mounting block 1010; two sliders 109 on the same block group are rotatably connected to a screw rod 1012, and the screw rod 1012 is slidably connected to the corresponding mounting block 1010; a slider 109 on the same block group is fixedly connected to a motor 1013, and the output shaft of the motor 1013 is fixedly connected to the corresponding screw rod 1012.

[0033] The clamping tube 106 is configured in a conical shape to reduce the volume of the lower end of the clamping tube 106 , making it easier for the clamping tube 106 to insert the needle body 8 between the dense needle bodies 8 on the IGBT module body 7 .

[0034] The telescopic end of the clamping tube 106 and the electric push rod Ⅰ105 are detachably connected, so when inserting needles 8 of different diameters, the clamping tube 106 and the clamping plate 107 can be quickly replaced to adapt to needles 8 of different diameters.

[0035] When in use, the IGBT module body 7 to be inserted is manually fixed on the cabinet 1 through the clamp 3, and then all the mounting blocks 1010 are aligned in a straight line by adjusting the assembly, so that the clamping cylinders 106 and clamping plates 107 on different mounting blocks 1010 can clamp the needle bodies 8 delivered by the feeder 2. Then, the feeder 2 is controlled to deliver the needle bodies 8 one by one to the leftmost clamping cylinder 106 and clamping plate 107 directly below. Taking the leftmost clamping cylinder 106 and clamping plate 107 clamping the needle body 8 as an example, the two electric push rods Ⅰ105 are controlled to drive the corresponding clamping cylinders 106 and the clamping plate 107 move in opposite directions to open the two clamping cylinders 106 and the clamping plate 107. Then, the cylinder 6 is controlled to drive the connecting frame 101 and the parts thereon to move downward until the needle body 8 is inserted into the two clamping cylinders 106 and the clamping plate 107 to a predetermined depth. Then, the two electric push rods Ⅰ105 are controlled to drive the corresponding clamping cylinders 106 and the clamping plate 107 to move in opposite directions so that the two clamping cylinders 106 and the clamping plate 107 clamp the needle body 8. Subsequently, the electric guide rail 4 is controlled to make the moving block 5 drive the cylinder 6 and the parts thereon to move left. , until the second clamping cylinder 106 and clamping plate 107 from left to right are located directly above the needle body 8. After the corresponding clamping cylinder 106 and clamping plate 107 are opened, the cylinder 6 is controlled again to drive the connecting frame 101 and the parts thereon to move downward, so that the second clamping cylinder 106 and clamping plate 107 clamp the needle body 8. Similarly, all the clamping cylinders 106 and clamping plates 107 clamp the needle body 8 in turn. Then, the cylinder 6 is controlled to drive the connecting frame 101 and the parts thereon to move up to the initial height. Subsequently, the electric guide rail 4 is controlled to make the moving block 5 drive the cylinder 6 and the parts thereon move to the right until the needle body 8 clamped by the clamping cylinder 106 and the clamping plate 107 corresponds to the pinhole on the IGBT module body 7, then, the control adjustment component makes the needle bodies 8 on different clamping cylinders 106 and clamping plates 107 correspond to the pinholes on the IGBT module body 7, then, the control cylinder 6 drives the connecting frame 101 and the rectangular plate 103 and the parts thereon to move downward, so that the rectangular plate 103 drives the clamping cylinder 106 and the clamping plate 107 to vertically insert the needle body 8 into the pinhole on the IGBT module body 7, completing the pin insertion operation.

[0036] Since the rectangular plate 103 is set at a forty-five degree inclination angle, compared with the horizontal rectangular plate 103, when the inclined rectangular plate 103 drives the clamping tube 106 and the clamping plate 107 to move downward, the distance between the rectangular plate 103 and the surrounding inserted needle bodies 8 is larger, and it is not easy to collide with the inserted needle bodies 8 to cause damage to the inserted needle bodies 8, and it is suitable for inserting needles 8 with small spacing.

[0037] The operation steps of the adjustment component are as follows: before the clamping cylinder 106 and the clamping plate 107 clamp the needle body 8, the control motor 1013 is started, and the output shaft of the motor 1013 drives the screw rod 1012 to rotate, and then the screw rod 1012 drives the mounting block 1010 and the parts thereon to slide in the front-back direction on the slide plate 1011 until all the mounting blocks 1010 are located at the frontmost side of the connecting frame 101 and are in the same straight line. After the clamping cylinder 106 and the clamping plate 107 clamp the needle body 8 and move to the top of the IGBT module body 7, the control motor 1013 is started again, and the output shaft of the motor 1013 drives the corresponding screw rod 1012 to rotate, so that different mounting blocks 1010 drive the clamping cylinder 106, the clamping plate 107 and the needle body 8 to be located above the corresponding pinhole on the IGBT module body 7, thereby realizing the simultaneous clamping of multiple needle bodies 8 and the simultaneous insertion of multiple needle bodies 8 into the IGBT module body 7;

[0038] When inserting the pin, the pinhole spacing on different IGBT module bodies 7 is different, so that the spacing between the left and right sides of the pin body 8 will also be different. Therefore, the electric slide rail 108 is controlled to make the slider 109 drive the corresponding slide plate 1011 and the mounting block 1010 to move in the left and right directions, and adjust the spacing of the mounting block 1010 in the left and right directions to adapt to different IGBT module bodies 7.

[0039] Example 2

[0040] On the basis of Example 1, Figure 3-Figure 6 As shown, it also includes an electric push rod II 201 and a connecting pipe 202; each fixed plate 104 is composed of a connecting plate I 1041 and a connecting plate II 1042 that are slidably connected to each other; one electric push rod I 105 is fixedly connected to the connecting plate I 1041, and the other electric push rod I 105 is fixedly connected to the connecting plate II 1042; each electric turntable 102 is bolted with an electric push rod II 201, and the telescopic end of the electric push rod II 201 is fixedly connected to the corresponding connecting plate II 1042, and the connecting plate II 1042 is fixedly connected to the rectangular plate 103; the clamping plate 107 is hollow, and each clamping plate 107 located on the corresponding connecting plate I 1041 is provided with a plurality of circular holes 1071 on its inner side; each clamping plate 107 located on the corresponding connecting plate I 1041 is connected to a connecting pipe 202.

[0041] A rubber strip is provided on the inner edge of the clamping plate 107 to enhance the sealing between the clamping plate 107 and the needle body 8 and improve the stability of the clamping plate 107 in adsorbing the needle body 8 .

[0042] The external pump is connected to the connecting pipe 202, and the two electric push rods Ⅰ105 located on the same mounting block 1010 are controlled to drive the corresponding clamping cylinder 106 and the clamping plate 107 to move toward each other, so that the clamping cylinder 106 and the clamping plate 107 clamp the needle body 8, and then the external pump is controlled to start, and the clamping plate 107 is sucked through the connecting pipe 202 located on the connecting plate Ⅰ1041, so that the corresponding clamping plate 107 vacuum adsorbs the needle body 8 through the circular hole 1071, and the needle body 8 is adsorbed on the clamping plate 107 located on the connecting plate Ⅰ1041. On the inside, then, while the cylinder 6 makes the connecting frame 101 drive the clamping cylinder 106 and the clamping plate 107 to insert the needle body 8 into the IGBT module body 7, the electric push rod Ⅱ201 is controlled to make the connecting plate Ⅱ1042 drive the corresponding clamping cylinder 106 and the clamping plate 107 to move upward, so that only one clamping plate 107 adsorbs the needle body 8 and then inserts it downward into the IGBT module body 7, further reducing the volume of the clamping cylinder 106 and the clamping plate 107 to insert the needle body 8 into the IGBT module body 7, so as to adapt to the smaller pitch of the pins.

[0043] Example 3

[0044] On the basis of Example 2, Figure 5-Figure 6 As shown, it also includes a spring rod II 301, a cone sleeve 302, an electric push rod III 304 and a pressure plate 305; a plurality of spring rods II 301 are fixedly connected in the clamping tube 106 on each connecting plate I 1041; the telescopic ends of all spring rods II 301 located on the same clamping tube 106 are respectively fixedly connected to a cone sleeve 302; an electric push rod III 304 is respectively fixedly connected in the clamping tube 106 on each connecting plate I 1041; and a pressure plate 305 is respectively fixedly connected to the telescopic end of each electric push rod III 304.

[0045] It also includes a distance sensor 303; each connecting plate II 1042 and connecting plate I 1041 is fixedly connected with a distance sensor 303. When the clamping cylinder 106 and the clamping plate 107 simultaneously insert multiple needle bodies 8 downward into the IGBT module body 7, the distance sensor 303 detects the distance between the corresponding clamping cylinder 106 and the clamping plate 107 and the IGBT module body 7, and then detects whether the depth of insertion of all the needle bodies 8 into the IGBT module body 7 is consistent.

[0046] When the slender needle body 8 is inserted into the IGBT module body 7, the slender needle body 8 is prone to bending due to its low rigidity. Therefore, when the clamping cylinder 106 and the clamping plate 107 move down to clamp the needle body 8, the cone sleeve 302 clamps the upper end of the needle body 8 under the elastic force of the spring rod II 301 to fix the upper end of the needle body 8, thereby improving the stability of the clamping cylinder 106 and the clamping plate 107 when inserting the needle body 8 into the IGBT module body 7. At the same time, the cone sleeve 302 guides and positions the needle body 8 to ensure that the needle body 8 is firmly fixed. The depth of the body 8 entering into the clamping cylinder 106 is determined. When the shorter needle body 8 is used to clamp the insertion pin, the upper end of the shorter needle body 8 does not enter the clamping cylinder 106 to a sufficient depth. As a result, when the clamping cylinder 106 and the clamping plate 107 move downward to insert the needle body 8 into the IGBT module body 7, the needle body 8 is easy to slide in the clamping cylinder 106 and the clamping plate 107, affecting the insertion pin. Therefore, the electric push rod III 304 is controlled to drive the pressure plate 305 to move downward, so that the pressure plate 305 is against the upper end of the shorter needle body 8, thereby improving the insertion effect.

[0047] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
