Description

Technical Field

[0001] The utility model relates to the field of PIN needle implantation, and particularly relates to a PIN needle implantation device. Background Art

[0002] With the development of IGBT products, various demands for PIN needle implantation have increased. According to the process characteristics of the products, the pin base needs to be welded to the product module, and this process often requires the PIN needles to be placed upside down on the product. There are two conventional ways of implanting PIN needles: (1) First, fix the PIN needles in the needle carrier according to the relative position requirements, with the pin base facing up and the tip of the needle facing down, and then cover the pin base with a cover plate (to prevent the PIN needles from falling when the needle carrier is subsequently flipped and buckled on the product), and then invert the needle carrier onto the product through a flipping mechanism. This solution has technical defects: during the process of extracting the cover plate, friction will occur between the pin base and the cover plate, resulting in wear and dust of the PIN needles. (2) Adopt a flexible jaw design. First, clamp the needle carrier, and then clamp the tip part of the PIN needle with the flexible jaw (to prevent the PIN needles from falling when the needle carrier is subsequently flipped and buckled on the product). At this time, rotate the needle carrier, and then buckle the needle carrier on the product, and the flexible jaw releases the PIN needles, thus completing the combination of the PIN needles and the product. This method can avoid the generation of dust due to friction between the cover plate and the pin base, but there are the following technical defects: 1. The flexible jaw is relatively large in volume, and a relatively large space interval is required between the jaws, which cannot adapt to products with densely distributed PIN needles; 2. The flexible jaw requires compressed air, increasing energy consumption and relatively high cost. Content of the Utility Model

Finally, the buckling and clamping mechanism releases the needle carrier, and the needle carrier together with the PIN needles disengages from the buckling and clamping mechanism under the action of the self-weight of the needle carrier, so that the way of making the needle carrier together with the PIN needles fall on the designated position of the product can effectively prevent the problem of PIN needle dropping when flipping the needle carrier during the PIN needle implanting process, and can also avoid the wear and dust phenomena generated during the PIN needle implanting process. At the same time, the use of a spring chuck for the chuck reduces the cost and allows the precise implantation of PIN needles with relatively dense spatial positions.

[0048] With the development of IGBT products, the demand for various implanted PIN needles has increased. According to the process characteristics of the product, the pin base needs to be welded to the product module. In this process, the PIN needles often need to be placed upside down on the product. There are two conventional methods for implanting PIN needles: (1) First, fix the PIN needles in the needle carrier according to the relative position requirements, with the pin base facing up and the tip facing down (to prevent the PIN needles from falling when the needle carrier is subsequently flipped and buckled on the product), then cover the pin base with a cover plate, and then invert the needle carrier onto the product through a flipping mechanism. This solution has technical defects: during the process of extracting the cover plate, friction will occur between the pin base and the cover plate, resulting in wear and dust of the PIN needles. (2) Adopt a flexible jaw design. First, clamp the needle carrier, and then clamp the tip part of the PIN needles through the flexible jaws. At this time, rotate the needle carrier, and then buckle the needle carrier on the product, and the flexible jaws release the PIN needles, thus completing the combination of the PIN needles and the product. This method can avoid the generation of dust due to friction between the cover plate and the pin base, but there are also the following technical defects: 1. The flexible jaws are relatively large in volume, and a relatively large interval space is required between the jaws, which cannot adapt to products with dense PIN needle distributions; 2. The flexible jaws require compressed air, increasing energy consumption and relatively high costs.

[0049] To this end, the utility model proposes a PIN needle implanting device, which can use a spring clamping mechanism to clamp the tip part of the PIN needle and implant the PIN needle on the needle carrier into the specified position of the product, avoiding wear and dust phenomena, reducing costs at the same time, and allowing the precise implantation of PIN needles with relatively dense spatial positions.

[0050] The following Figures 1-5 , describes in detail the PIN needle implanting device according to the embodiments of the present utility model.

[0051] Refer to Figure 1 and Figure 4, in the embodiment of the present utility model, a PIN needle planting device is proposed, including: a needle carrier 100, a lifting and clamping mechanism 200, a buckling and clamping mechanism 300, a thimble mechanism 400, a needle clamping mechanism 500 and a flipping mechanism 600. Specifically, the needle carrier 100 is used to carry PIN needles 700; the lifting and clamping mechanism 200 is used to clamp or release the needle carrier 100; the buckling and clamping mechanism 300 is arranged below the lifting and clamping mechanism 200, and the buckling and clamping mechanism 300 can rise and fall; the thimble mechanism 400 is arranged on one side of the lifting and clamping mechanism 200 close to the buckling and clamping mechanism 300, and the needle carrier 100 is located below the thimble structure 400; the needle clamping mechanism 500 is arranged on one side of the buckling and clamping mechanism 300 close to the lifting and clamping mechanism 200. When the buckling mechanism 300 drives the needle clamping mechanism 500 to rise to the thimble mechanism 400, the thimble structure 400 can push the PIN needles 700 on the needle carrier 100 into the needle clamping mechanism 500; the flipping mechanism 600 is connected to the buckling and clamping mechanism 300, and the flipping mechanism 600 is used to flip the buckling and clamping mechanism 300 and the needle clamping mechanism 500. In this embodiment, specifically, according to the product requirements, the needle carrier 100 is provided with a plurality of needle holes for carrying PIN needles 700 at specific positions. The PIN needles 700 are vertically placed in the needle holes with the needle seats facing up and the needle tips facing down, and the needle tip parts of the PIN needles in the needle holes can be pushed out of the needle carrier 100 by an external force from top to bottom. The lifting and clamping mechanism 200 and the buckling and clamping mechanism 300 are arranged opposite to each other up and down. The thimble mechanism 400 is fixedly attached to the bottom of the lifting and clamping mechanism 200, that is, fixedly arranged on one side of the lifting and clamping mechanism 200 close to the buckling and clamping mechanism 300. The thimble mechanism 400 can push the needle tip parts of the PIN needles 700 on the needle carrier 100 out from the lower surface of the needle carrier 100; the needle clamping mechanism 500 is fixedly attached to the top of the buckling and clamping mechanism 300, that is, fixedly arranged on one side of the buckling and clamping mechanism 300 close to the lifting and clamping mechanism 200. The needle clamping mechanism 500 is used to clamp the needle tip parts of the PIN needles 700 pushed out of the needle carrier 100 by the thimble mechanism 400; when the flipping mechanism 600 flips, it flips the buckling and clamping mechanism 300 together with the needle clamping mechanism 500 and the needle carrier 100 as a whole by 180°, so as to achieve the effect of making the buckling and clamping mechanism 300 together with the needle clamping mechanism 500 and the needle carrier 100 upside down as a whole, so that the PIN needles jointly clamped by the needle carrier 100 and the needle clamping mechanism 500 are in a vertical state with the needle seats facing down and the needle tips facing up.During operation, first, the lifting and clamping mechanism 200 clamps the needle carrier 100 from other devices. Subsequently, the lifting and clamping mechanism 200, together with the clamped needle carrier 100, is lifted vertically upward by a certain height, providing a certain reserved space for the subsequent engagement clamping mechanism 300 to be lifted below the clamping mechanism 200 to clamp the needle carrier 100 and perform the thimble action. The lifting and clamping mechanism 200 can mainly serve as a clamping transfer device for the needle carrier 100 and facilitate the accurate positioning of the needle carrier 100. When the lifting and clamping mechanism 200 firmly clamps the needle carrier 100 and lifts it by a certain height, the engagement clamping mechanism 300 is adjusted to directly below the lifting and clamping mechanism 200, making the upper surface of the needle carrier 100 vertically opposite to the lower surface of the thimble mechanism 400. Subsequently, the engagement clamping mechanism 300 rises until the upper surface of the needle clamping mechanism 200 fits against the lower surface of the needle carrier 100. Then, the clamping part of the engagement clamping mechanism 300 clamps the needle carrier 100, and at the same time, the lifting and clamping mechanism 200 releases the needle carrier. The engagement clamping mechanism 300 drives the needle carrier 100 to continue rising, so that under the acting force of the PIN needle 700 on the needle carrier 100 against the thimble mechanism 400, the tip part of the PIN needle 700 is ejected from the lower surface of the needle carrier 100, while the socket part of the PIN needle 700 remains in the needle carrier 100. At the same time, the needle clamping mechanism 500 clamps the tip part of the ejected PIN needle 700 under the action of the internal spring force. Subsequently, the engagement clamping mechanism 200 drives the entire needle carrier 100 to descend, making the space between the needle carrier 100 and the thimble mechanism 400 sufficient for the rotation mechanism 600 connected to the engagement clamping mechanism 300 to drive the engagement clamping mechanism 300 and the needle carrier 100 to perform a flipping action. Then, the rotation mechanism 600 connected to the engagement clamping mechanism 300 drives the entire engagement clamping mechanism 300 and the needle carrier 100 to rotate by 180°, so as to achieve the effect of turning the engagement clamping mechanism 300 together with the needle clamping mechanism 500 and the needle carrier 100 upside down, making the PIN needle 700 jointly clamped by the needle carrier 100 and the needle clamping mechanism 500 in a vertical state with the socket facing down and the tip facing up. When the needle carrier 100 reaches above the specified position, the needle carrier 100 is positioned on the tray positioning fixture. The engagement clamping mechanism 300 releases the needle carrier 100, and then the entire engagement clamping mechanism 300 is lifted. At this time, the needle carrier 100, together with the PIN needle 700 fixed to the needle carrier 100 at the socket, separates from the needle clamping mechanism 200 under the self-weight of the needle carrier 100. Thus, the needle carrier 100 and the PIN needle 700 fall onto the specified position of the product. Finally, a needle pressing block is used to press the PIN needle 700 that has fallen onto the product to the required height, thereby completing the operation of implanting the PIN needle.

[0052] Refer to Figure 2, Further, in some embodiments of the present utility model, the lifting and clamping mechanism 200 includes a first frame 210 and a first jaw cylinder 220. The first jaw cylinder 220 is disposed on the first frame 210, and the first jaw cylinder 220 is used to clamp or release the needle carrier 100; the ejector pin mechanism 400 is disposed on the first frame 210, and the ejector pin mechanism 400 is located inside both sides of the first jaw cylinder 220. In this embodiment, specifically, the first frame 210 is provided as a double-layer structure. The upper layer is used to fix the cylinder driving part of the jaw cylinder 220, and the lower layer is used to fix the ejector pin mechanism 400. The upper part of the jaw part of the jaw cylinder 220 is connected to the cylinder driving part, and the lower part extends to directly below the ejector pin mechanism 400, so that the ejector pin mechanism 400 is surrounded inside the left and right sides of the first jaw cylinder 220 and is used to directly contact and hold the needle carrier 100. When the jaw cylinder 220 holds the needle carrier 100, the cylinder driving part provides driving force for the jaw part, so that the jaw cylinder 220 clamps or releases the left and right edges of the needle carrier 100 from the left and right directions respectively, and keeps the needle carrier 100 in a horizontal state.

[0053] Refer to Figure 2 , Further, in some embodiments of the present utility model, the lifting and clamping mechanism 200 further includes a first lifting device 230. The first lifting device 230 is connected to the first frame 210, and the first lifting device 230 is used to drive the first frame 210 to rise and fall. In this embodiment, the first lifting device 230 is connected to the upper layer of the first frame 210, and the first lifting device 230 drives the whole first frame 210 to rise and fall through a slide rail structure.

[0054] Refer to Figure 2, Further, in some embodiments of the present utility model, the thimble mechanism 400 is connected to the first frame 210 through a plurality of connecting columns 211, and a spring 212 is sleeved on the outer wall of each connecting column 211. In this embodiment, specifically, the thimble mechanism 400 is fixedly arranged on the lower layer of the first frame 210, and the upper layer and the lower layer of the first frame 210 are connected by four connecting columns 211. The connecting columns 211 are divided into a thick rod part and a thin rod part. The thick rod part has a structure of a hollow thick rod, and its inner diameter can just sleeve the thin rod part. A section of ring is sleeved on the thin rod part, which can be used to increase the outer diameter of a section of the thin rod part. And a spring 212 is sleeved on each connecting column 211. The upper end of the spring 212 abuts against the lower surface of the thick rod part, and the lower end abuts against the upper surface of the ring sleeved on the thin rod part, so as to realize the telescopic and restoration of the connecting column 211. When the thimble mechanism 400 abuts against the needle carrier 100 for thimbling, the spring 212 can provide a part of the pressure from top to bottom and play a buffering role. When the needle carrier 100 is separated from the thimble mechanism 400, under the elastic force of the spring 212, the position of the thimble mechanism 400 is restored. Using the structure in which the telescopic connecting column 211 and the spring 212 cooperate with each other can provide buffering when the thimble mechanism 400 and the needle carrier 100 press against each other, prevent equipment damage caused by excessive pressing force between the needle carrier 100 and the thimble mechanism 400 due to too large an upward amplitude of the needle carrier 100, and at the same time, after the thimble mechanism 400 and the needle carrier 100 press against each other, the position of the thimble mechanism 400 can be restored.

[0055] Refer to Figure 3, Further, in some embodiments of the present utility model, the fastening and clamping mechanism 300 includes a second frame 310 and a second jaw cylinder 320. The second frame 310 is located below the lifting and clamping mechanism 200; the second jaw cylinder 320 faces the lifting and clamping mechanism 200 and is used to clamp or release the needle carrier 100; the needle clamping mechanism 500 is disposed on the second frame 310 and is located inside the two sides of the second jaw cylinder 320; a second lifting device 330 is connected to the second frame 310, and the second lifting device 330 is used to drive the second frame 310 to rise and fall. In this embodiment, specifically, the fastening and clamping mechanism 300 is integrally located directly below the lifting and clamping mechanism 200, including a second frame 310 and a second jaw cylinder. The second frame 310 is divided into upper and lower layers. The upper layer is used to fix the needle clamping mechanism 500 and place the needle carrier 100, and the lower layer is used to fixedly arrange the cylinder driving part of the second jaw cylinder 320. The jaw part of the second jaw cylinder 320 extends upward from the front and rear directions of the cylinder driving part of the jaw cylinder 320 to the upper part of the needle clamping structure 500, that is, surrounds the upper layer from the front and rear directions. The jaw part of the second jaw cylinder 320 is used to directly clamp the needle carrier 100; the second lifting device 330 is connected to the lower layer of the second frame 310 and adopts a sliding rail lifting structure, which can drive the overall lifting of the fastening and clamping mechanism 300. When the fastening and clamping mechanism 300 clamps the needle carrier, first drive the second lifting device 330 to drive the fastening and clamping mechanism 300 to rise to the height where the upper surface of the needle clamping mechanism 500 is in contact with the lower surface of the needle carrier 100. Subsequently, the second jaw cylinder 320 clamps the needle carrier 100 from the front and rear directions, and at the same time, the first jaw cylinder 220 releases the needle carrier 100 from the left and right directions. The spatial position and the angles in all directions of the needle carrier 100 remain unchanged. Then, continue to lift the fastening and clamping mechanism 300 to complete the needle pushing.

[0056] Refer to Figure 4 and Figure 5, Further, in some embodiments of the present utility model, a chuck 510 is provided on one side of the needle clamping mechanism 500 facing the thimble mechanism 400. The chuck 510 is used to clamp the PIN needles 700 on the needle carrier 100. In this embodiment, specifically, the entire chuck 510 is completely embedded in the plate body of the needle clamping mechanism 500. The chuck 510 is composed of a needle insertion hole 511 and a spring slider 512. When the chuck 510 is in a state of not clamping the PIN needles 700, the spring slider 512 completely blocks the needle insertion hole 511 from the inside of the needle clamping mechanism 500 under the elastic force of the spring. A chamfer is provided on the upper surface of the part of the spring slider 512 blocking the needle insertion hole 511, and the chamfer is preferably 45° to facilitate the insertion of the tip of the PIN needle 700. When the needle clamping mechanism 500 clamps the tip of the PIN needle, driven by the second lifting device 330, the needle clamping mechanism 500 together with the needle carrier 100 presses upward against the thimble structure 400. The thimble structure 400 vertically presses the tip part of the PIN needle 700 in the needle carrier 100 from top to bottom onto the chamfer of the spring slider 512 in the needle insertion hole 511. Under the action of the chamfer of the spring slider 512 changing the pressure direction, the tip part of the PIN needle 700 is smoothly squeezed into the gap between the spring slider 512 and the needle insertion hole 511 and creates a gap between the two. Since this gap is formed by the mutual extrusion of the spring slider 512 and the tip of the PIN needle 700, under the elastic force of the spring of the spring slider 512, this gap can just clamp the tip part of the PIN needle 700, thus completing the clamping of the tip part of the PIN needle 700 by the needle clamping mechanism 500.

[0057] Referring to Figure 3 , Further, in some embodiments of the present utility model, the flipping mechanism 600 includes: a flipping driving device 610 and a flipping platform 620. The flipping driving device 610 is connected to the flipping platform 620. The flipping driving device 610 is used to drive the flipping platform 620 to flip; the buckling and clamping mechanism 300 is arranged on the flipping platform 620. In this embodiment, specifically, the flipping driving device 610 includes a fixing plate 611 with a circular rotation hole 611a and a stepping motor 612. The stepping motor 612 plays a role in driving the flipping. A square (or rectangular) fixing plate 611 with a circular rotation hole 611a is fixed below the stepping motor 612. A screw hole 611a is provided on the front side plate surface of the fixing plate 611 and is fixed at a preset position such as a wall surface using screws. The rear side plate surface of the fixing plate 611 is fixedly connected to the flipping platform 620 through the circular rotation hole 611b, thereby realizing the rotatable connection between the flipping driving device 610 and the flipping platform 620. When flipping, the stepping motor 612 applies a driving force to the circular rotation hole 611a through the internal gear of the flipping driving device 620, thereby driving the circular rotation hole 611a and the flipping platform 620 fixed thereto to flip by 180°, thus completing the entire flipping process.

[0058] Referring to Figure 2 , further, in some embodiments of the present utility model, the PIN inserting device further includes a mounting plate 240, and the lifting clamping mechanism 200 is fixedly connected to the mounting plate 240. In this embodiment, the mounting plate 240 can be rectangular or square, and its area size should ensure the stable fixation of the lifting clamping mechanism 200 in terms of structure.

[0059] Referring to Figure 2 , further, in some embodiments of the present utility model, a plurality of mounting holes 241 are provided on the mounting plate 240. In this embodiment, the mounting plate 240 is fixed at a preset position such as a wall surface by a plurality of screws, so as to prevent the lifting clamping mechanism 200 from falling off in terms of structure.

[0060] Referring to Figure 4 and Figure 5 , further, in some embodiments of the present utility model, the ejector pin structure 400 includes an ejector pin plate 410, and a plurality of ejector pin columns 420 are provided on one side of the ejector pin plate 410 facing the pin carrier 100. In this embodiment, specifically, each ejector pin column 420 corresponds to a PIN pin 700, and each ejector pin column 420 is disposed directly above the corresponding PIN pin 700. The ejector pin column 420 is cylindrical, and its outer diameter is basically the same as the pin seat part of the PIN pin 700. When ejecting the pin, a pressure from top to bottom is applied to each PIN pin 700 through the ejector pin column 420, so as to push the tip part of the PIN pin 700 in the pin carrier 100 into the pin clamping mechanism 500.
