Detailed Description

Referring to fig. 1 to 14, a feeding device of the present invention includes a mounting base 1, a feeding mechanism 2, and a processing unit 3, wherein the mounting base 1 has a conveying path 11, and the conveying path 11 can accommodate passage of an electronic component connecting body formed by connecting belts; a feeding mechanism 2 for conveying the electronic component connection body along the conveying path 11; the processing assembly 3 comprises a supporting seat 31 for supporting the electronic component connecting body transferred on the conveying path 11, a limiting mechanism 32 and a cutting forming mechanism 33, wherein two sides of the supporting seat 31 are provided with side wall parts 311 for supporting pins at two ends of the electronic component, the limiting mechanism 32 is matched with the side wall parts 311 to limit the pins at two ends of the electronic component, and the cutting forming mechanism 33 can be matched with the side wall parts 311 to sequentially cut the distal ends of the pins at two ends of the electronic component and bend the remaining ends of the pins at two ends of the electronic component. In this application, the electronic component connecting body is formed by firmly adhering electronic components one by a braid, as shown in fig. 14, it can be seen that each electronic component is arranged at intervals, and two ends of each electronic component are adhered to the braid respectively, so that the feeding mechanism 2 is convenient for feeding. It should be noted that, in this application, since the pin length of each electronic component is preset too long, the processing module 3 in this application can be adapted to the requirements of the plug-ins with different specification lengths, and of course, in this embodiment, the cutting and forming mechanism 33 is only adapted to the pin processing with one specification length to reduce the production cost.

Referring to fig. 4 to 5, in the present application, the feeding mechanism 2 includes a telescopic member 21 mounted on the mounting base 1, and a pair of feeding arms 22, the telescopic member 21 being a cylinder in the present application. The pair of feed arms 22 are arranged in parallel, and are integrally connected at one end near the telescopic member 21 by a connecting block. One end of the feeding arm 22 is movably connected with the telescopic member 21, the other end of the feeding arm is provided with a ratchet 23, and the telescopic member 21 can drive the feeding arm 22 to drive the electronic component connecting body to forward at least one distance of the electronic components along the conveying direction of the conveying path 11 by utilizing the ratchet 23. Because of the arrangement of the ratchet 23, the electronic component connecting body is not reversely fed through the ratchet 23 when the telescopic action of the telescopic member 21 drives the ratchet 23 to act. In the present embodiment, the feeding arm 22 is mounted on the electronic component connecting body, for example, when the feeding arm 22 is mounted under the electronic component connecting body, the feeding arm 22 is inclined from top to bottom to front Fang Dingtui sub-component connecting body; and when the feeder arm 22 is mounted over the electronic component joint, the electronic component connecting body is pressed by the self weight of the feed arm 22. The two mounting arrangements each have their own advantages, and the present application uses the resulting design of the mounting of the feeder arm 22 under the electronic component connection from a combination of considerations and feeding issues.

Further, a sliding rail 24 is arranged at the bottom of the conveying path 11, and a hole through which one end of the feeding arm 22, which is close to the ratchet 23, can pass is formed at one end of the sliding rail 24, which is close to the processing assembly 3, and can be understood as a movable hole; of course, if the sliding rail 24 is not mounted on the sliding rail 24, no hole needs to be formed, and the feeding arm 22 and the telescopic member 21 are mounted on the sliding rail 24 so as not to affect the movement of the electronic component connecting body, so that the whole structure is more attractive. Wherein, the feeding arm 22 is installed on the sliding track 24 through the sliding block 25, the middle part of the feeding arm 22 is movably hinged on the sliding block 25, one end of the feeding arm 22, which is positioned on the ratchet 23, can movably pass through the conveying path 11, and an elastic piece 26 is arranged between one end of the feeding arm 22, which is far away from the ratchet 23, and the sliding block 25; in this application the hinge point of the feed arm 22 is not coplanar with the plane in which the telescopic member 21 is telescopic, whereas in this application the plane in which the telescopic member 21 is telescopic is below the hinge point of the feed arm 22 for better actuation, so that the telescopic member 21 can generate a moment pushing the feed arm 22 to swing upwards counter-clockwise. The main function of the elastic element 26 in the present application is to prevent the connection point between the feeding arm 22 and the telescopic member 21 from jamming when the movement is switched, and to ensure that the feeding arm 22 is positioned at one end of the ratchet 23 to maintain the required limited movement according to the movement of the telescopic member 21.

Thus, when the telescopic member 21 brings the feeding arm 22 back, the feeding arm 22 swings clockwise, the elastic piece 26 is compressed and the ratchet 23 exits the conveying path 11; when the telescopic member 21 drives the feeding arm 22 to push forwards, the feeding arm 22 swings anticlockwise, the elastic piece 26 resets, the ratchet 23 moves through the conveying path 11 and pushes the electronic component connecting body forwards. It can be seen that in this embodiment the feeder arm 22 resembles a lever, the middle of which can be swung, while being well adapted to the pushing demands of the different stages. Because of the mounting structure of the feeding arm 22, the end of the telescopic member 21, which is close to the ratchet 23, is completely hidden under the sliding track 24 or completely separated from contact with the electronic component after the telescopic member is completely retracted, and the movement of the electronic component connecting body is not affected. Therefore, a feeding mode of a mode of swinging and pushing forward of the feeding arm 22 can be seen, the whole electronic component connector can be well avoided, and interference of movement is avoided. In addition, when the telescopic member 21 drives the feeding arm 22 to push forward for feeding, the feeding arm 22 swings anticlockwise in addition to sliding forward, the elastic piece 26 resets, the ratchet 23 moves through the conveying path 11 and pushes the electronic component connecting body forward, and meanwhile, the ratchet 23 pushes the whole electronic component connecting body obliquely upwards, so that friction force between the electronic component connecting body and the sliding rail 24 is reduced, and feeding is facilitated to a certain extent.

In addition, referring to fig. 5, the connection point of the feeding arm 22 and the telescopic member 21 can only be movably connected due to the above-mentioned problem that the feeding arm 22 needs to swing during sliding. For better power transmission, the application provides a connecting mode. The sliding block 25 is provided with a movable groove 27, the output end of the telescopic member 21 is movably clamped in the movable groove 27, and the output end of the telescopic member 21 can slide in the movable groove 27 along the length direction. The movable slot 27 may be a complete chute or an open slot, and the output end of the telescopic member 21 is provided with adjusting nuts matched with two sides of the movable slot 27, and the distance between the adjusting nuts at two sides can be adjusted according to the swing amplitude of the feeding arm 22. The elastic piece 26 can well prevent the telescopic member 21 from being separated from the open movable groove 27.

Referring to fig. 6 to 10, the handling assembly 3 is further provided with a lifting mechanism 34; the lower part of the limiting mechanism 32 is movably sleeved on the output end of the lifting mechanism 34, the lower part of the cutting forming mechanism 33 is connected to the output end of the lifting mechanism 34, and the cutting forming mechanisms 33 drive the limiting mechanism 32 to act through the travel position structure 35 in a delayed mode. In this application, for better power saving and power conversion, the lifting mechanism 34 is provided with only one set, and the travel position structure 35 can take on many different types of conventional structures, wherein the following embodiments are given in this application. Wherein, be provided with connecting axle 36 on elevating system 34's the output, and elevating system 34 is the telescopic cylinder of priority in this application, and the flexible direction sets up downwards, and the movement interference of stop gear 32 and cut forming mechanism 33 can be avoided well to the setting downwards. The lifting mechanism 34 is mounted at the bottom of the supporting seat 31 through a mounting bracket 37, a moving hole which is matched with the limiting mechanism 32 and the cutting forming mechanism 33 to move is arranged in the supporting seat 31, and a moving cavity or a hole position of the connecting shaft 36 is also arranged. In this application, the structure of the connecting shaft 36 is correspondingly changed, and in this application, the lower part of the limiting mechanism 32 is movably sleeved on the connecting shaft 36, and the upper end of the connecting shaft 36 is hinged with the lower end of the cutting forming mechanism 33.

Referring to fig. 8-10, a specific construction of the travel range structure 35 is presented for better movement. The stroke position structure 35 is provided with a stroke groove 351 on the limiting mechanism 32, and the lower part of the cutting forming mechanism 33 is arranged on the output end of the lifting mechanism 34 in a way that the rotating shaft 352 passes through the stroke groove 351; when the lifting mechanism 34 moves up or down, the cutting forming mechanism 33 drives the limiting mechanism 32 to move through the cooperation delay of the travel groove 351 and the rotating shaft 352. In the present application, because the pin of the electronic component must be pressed by the limit mechanism 32 firstly and then cut and bent by the cutting-out mechanism 33, if the length of the travel groove 351 is properly set, the limit mechanism 32 can be carried out by matching the travel groove 351 with the rotating shaft 352 when the cutting-out mechanism 33 moves to a certain extent in the present application, so that the time-delay action can be realized; when the device descends, the limiting mechanism 32 is driven to compress through the top of the travel groove 351, and meanwhile the cutting and shaping mechanism 33 completes cutting and bending actions. The structure that only passes through the travel groove 351 and the rotating shaft 352 can be read, and the specification, the size and the design of the whole travel position structure 35 and other parts of the processing assembly 3 are required to be high, so in order to solve the above problem, the application is improved on the basis of the above, wherein the connecting shaft 36 is provided with the limit step 38 for the limit limiting mechanism 32 to move downwards, the buffer element 39 is arranged between the limit step 38 and the supporting seat 31, and the buffer element 39 can be a spring preferably. When the limiting step 38 is set to be in contact with the lower end of the limiting mechanism 32, the bottom of the travel groove 351 is not in contact with the rotating shaft 352, so that the lifting of the limiting mechanism 32 is carried up by the limiting step 38; when the cutting and forming mechanism 33 and the limiting mechanism 32 descend simultaneously, in the application, the limiting mechanism 32 is firstly contacted with the pins of the electronic component, meanwhile, the limiting mechanism is limited and cannot move downwards continuously, the cutting and forming mechanism 33 also needs to move downwards continuously, therefore, after the limiting mechanism 32 compresses the pins of the electronic component, the top of the travel groove 351 cannot be contacted with the rotating shaft 352, and the rotating shaft 352 can slide relatively in the travel groove 351 continuously.

The motion principle of the whole processing assembly 3 is as follows: when the feeding mechanism 2 feeds the supporting seat 31, the lifting mechanism 34 is lifted, which will inevitably drive the cutting and forming mechanism 33 to lift up in the supporting seat 31, and due to the arrangement of the limiting step 38 and the relationship between the travel groove 351 and the rotating shaft 352 in the present application, both the cutting and forming mechanism 33 and the limiting mechanism 32 are lifted up, and the electronic component at the foremost end of the whole electronic component connecting body will be resisted by the limiting mechanism 32. When the electronic component is in place, the lifting mechanism 34 descends to drive the cutting forming mechanism 33 and the limiting mechanism 32 to descend, and the descending speeds of the cutting forming mechanism 33 and the limiting mechanism can be consistent or different due to the stroke position structure 35. In the present application, the cutting and forming mechanism 33 and the limiting mechanism 32 firstly descend synchronously, after the limiting mechanism 32 descends to start to contact the pins of the electronic component, the cutting and forming mechanism 33 continues to move downwards due to the buffer piece 39, meanwhile, the reaction force of the buffer piece 39 makes the acting force of the limiting mechanism 32 for pressing the pins of the electronic component gradually become larger, and at the same time, the cutting and forming mechanism 33 can complete the actions of cutting and bending the pins sequentially or simultaneously. At this time, when the cutting and forming mechanism 33 runs to the maximum stroke, the bottom of the stroke groove 351 may or may not contact with the rotating shaft 352, and the buffer member 39 is introduced, so that the effect of driving the limiting mechanism 32 to compress the pins of the electronic component by matching the bottom of the stroke groove 351 with the rotating shaft 352 is reduced or even eliminated. While in the lifting process, the top of the travel groove 351 and the rotating shaft 352 still have obvious functions, and the limit mechanism 32 can be still carried by matching the rotating shaft 352.

Referring to fig. 6 to 10, in order to better facilitate cutting and bending of the whole electronic component in the present application, the top of the supporting seat 31 is provided with a guide block 312 communicating with the conveying path 11, the side wall portions 311 are disposed at two sides of the guide block 312, and the top portion extends out of the upper end of the guide block 312 to form a guide groove 313 for allowing the electronic component to pass through; the guiding groove 313 is mainly used for accommodating the electronic component body, so that the problem that the side wall portion 311 is not contacted with the pins of the electronic component is avoided. And stop gear 32 is located the pressure head 321 that the both sides of guide block 312 all were provided with cooperation lateral wall portion 311 and compress tightly electronic component both ends pin, stop gear 32 still is provided with and is connected with connecting rod 322 with pressure head 321 in this application, and connecting rod 322 is provided with two sets of, set up respectively in the both sides of pressure head 321, but connecting rod 322 movable cartridge is in the motion hole in bearing 31 simultaneously, two sets of connecting rod 322 lower extreme is connected with connecting seat 323, and connecting seat 323 movable cartridge is on connecting axle 36, the both sides wing of connecting seat 323 is provided with the wing portion 324 that is used for installing bolster 39, of course be provided with the installation pit that is used for spacing bolster 39 on the wing portion 324. While the travel groove 351 is installed on the sidewall of the connection rod 322, it can be simply understood that the two sets of connecting rods 322 are symmetrically provided with the travel grooves 351. In the present application, because the position of the electronic component pin to be pressed is the proximal end of the electronic component near the body, two pressing tongues 325 are provided on the pressing head 321, and wedge grooves are provided at the lower ends of the inner sides of the two pressing tongues 325, so as to facilitate correction of the position of the whole electronic component on the guide groove 313; the pressing tongue 325 can simultaneously press a plurality of electronic components in cooperation with the side wall portion 311. In addition, a positioning step is arranged at the joint of the pressure head 321 and the connecting rod 322, and when the whole pressure head 321 rises to the highest point, the positioning step faces the side wall part 311, so that the movement of the forefront electronic element can be effectively resisted, and the electronic element is positioned in an auxiliary mode.

Referring to fig. 10, since the pins on both sides of the electronic component need to be cut, the cutting mechanism 33 is provided with a bending head 331 and a cutter 332 on the inner and outer sides of the pressing head 321 on each side; the outer edges on both sides of the supporting seat 31 are provided with supporting edges 314 for supporting the outer ends of pins at both ends of the electronic component, when the bending head 331 and the cutter 332 descend synchronously, the cutter 332 is matched with the supporting edges 314 to cut off the distal ends of the pins at both ends of the electronic component, and then the bending head 331 is matched with the side wall part 311 to bend the remaining ends of the pins at both ends of the electronic component. For better avoidance, the entire ram 321 in this application is disposed above the cut-forming mechanism 33. In the present application, since the distal end of the lead is cut first and then the proximal end of the lead is bent, the lower edge of the cutter 332 is lower than the lower edge of the bending head 331, so that the cutter 332 acts on the distal end of the electronic component first and contacts the proximal end of the lead of the electronic component after cutting the lead by bending the elbow 331 when the cutting and forming mechanism 33 is lowered as a whole. The support edge 314 can better support both sides of the whole electronic component connecting body, so as to be convenient for cutting off the distal ends of the pins of the electronic component by matching with the cutter 332.

The clearance is necessary between the guide arc portion 333 and the side wall portion 311, and if the clearance is too small, the pin is likely to be jammed between the guide arc portion 333 and the side wall portion 311 during bending, or even deformed. In this application, the bending head 331, the cutter 332, and the pressing head 321 are all L-shaped in shape, and the laterally parallel ends are directed to the feeding side of the electronic component connecting body.

The feeding device is provided with a conveying path 11 for guiding an electronic component connecting body on a mounting base body 1, and the electronic component connecting body is conveyed forward by a feeding mechanism 2; meanwhile, pins at two ends of the electronic component are limited by the limiting mechanism 32 in cooperation with the side wall part 311, and the cutting and forming mechanism 33 in cooperation with the side wall part 311 sequentially cuts the distal ends of the pins at two ends of the electronic component and bends and forms the remaining ends of the pins at two ends of the electronic component. The whole feeding device can rapidly cut and separate single electronic elements one by one, and simultaneously reshape pins of the single electronic elements, so that plug-in devices outside the later period can be conveniently taken; the device has small structure and powerful functions, and can be effectively assembled and combined with the existing plug-in equipment.

Referring to fig. 11 to 13, for some electronic components, not only a bending operation is required, but also a secondary bending operation is required, and even the leads are deformed. For this purpose, the invention also provides an electronic component supply device, which comprises a shaping blanking device 4 and the feeding device; the shaping and blanking device 4 can be matched with the side wall parts 311 on two sides to perform indentation and bending on pins on two ends of the bent electronic component, and send out the electronic component with the indentation along the conveying direction of the conveying path 11.

Referring to fig. 11 and 12, the plastic blanking device 4 includes a mounting seat 41 connected with the supporting seat 31, a clamping swing piece 42 and a driving member 43; in this embodiment, the driving member 43 is preferably an air cylinder, two groups of clamping pendulums 42 are provided and are respectively and swingably mounted on corresponding positions of the side wall portions 311 on two sides of the supporting seat 31, the driving member 43 is mounted on the mounting seat 41, the output end of the driving member is hinged with the clamping pendulums 42 on two sides through the driving rod 44, and the driving member 43 can drive the two groups of clamping pendulums 42 to press and bend pins of the electronic component through the driving rod 44 in cooperation with the corresponding side wall portions 311. In the present application, the clamping swing piece 42 includes a connecting body 421, a hinge 422 connected to one side of the connecting body 421, and a folding head 423 disposed on the other side of the connecting body 421. Due to the compactness of the mounting structure, in the present application, the lower end of the connection body 421 is rotatably mounted on the supporting seat 31, and the upper end is suspended. In order to balance the power and match the structure of the processing unit 3, the folding heads 423 are disposed on the upper portion of the connecting body 421, so as to match the corresponding positions of the side wall portions 311. While the hinge 422 is provided at the lower portion of the connection body 421, which reduces the installation height of the entire driving member 43. Because of special requirements of some processing, small-radian folds or large-angle folds are required to be formed on the pins. Therefore, only the description of the small-arc crease is made in this application, wherein the crease groove 315 is provided at the preset position on the side wall portion 311, and the creasing protrusion 424 matching with the crease groove 315 is provided on the creasing head 423 except that the acting surface is the whole plane. It should be noted that, after the clamping swing piece 42 rotates by a certain angle, the working surface of the folding head 423 can be opposite to and closely attached to the side surface of the side wall 311, so that the folding head 423 protrudes outwards relative to the connecting body 421, and after eccentric rotation, the folding head 423 can contact with the side surface of the side wall 311 without motion interference. Two ends of the driving rod 44 are respectively connected with the hinge 422 and the output end of the driving member 43, and two groups of driving rods 44 and the output end of the driving member 43 form a fork head capable of outwards opening and closing.

In addition, referring to fig. 13, in order to better feed, since the above-mentioned processing assembly 3 and the shaping and blanking device 4 have different actions, both the processing assembly 3 and the processing assembly 3 act together and the processed electronic component needs to be pushed out, therefore, the electronic component feeding device further includes a pushing assembly 5, the pushing assembly 5 includes a pushing member 51 mounted on the mounting seat 41 and/or the supporting seat 31, and a pushing fork 52 mounted on an output end of the pushing member 51, two ends of the pushing fork 52 are respectively disposed on outer sides of the side wall portions 311 on two sides, and the pushing member 51 can send the folded electronic component out of the supporting seat 31 through the pushing fork 52. Pushing fork 52 is relatively simple and therefore not described in detail herein. When the pushing fork 52 pushes the material, the inner sides of the two fork parts of the pushing fork 52 are closely attached to the outer sides of the side wall parts 311, and the electronic component body slides in the guide groove 313, so that the pins are closely attached to the outer sides of the side wall parts 311 because the pins are bent, and the two fork parts of the pushing fork 52 can be matched with the side wall parts 311 to push the whole electronic component outwards. Of course, in order to avoid the interference of the movement, a gap for avoiding the movement of the pushing fork head 52 is further provided on the inner side of the upper end of the connection body 421, so as to avoid the influence of the rotation process of the connection body 421 on the pushing fork head 52.
