Description

Technical Field

[0001] The present invention belongs to the field of electronic component manufacturing, and particularly relates to a semi-automatic installation jig for connector Pin pins. Background Art

[0002] In the field of precision electronic component manufacturing, the installation of pin pins is one of the core processes. The traditional installation method mainly relies on manual operation. The operator needs to insert the pin pins into the corresponding installation holes one by one. However, the existing technology has significant defects: First, it is difficult to ensure absolute perpendicularity with manual force application. Deviation in the installation direction is likely to cause the pin pins to bend or tilt, affecting the contact stability. Second, manual installation cannot control the uniformity of the force applied to each pin pin, resulting in uneven heights of the pin pins after installation, affecting the overall performance of the device. In addition, frequent manual operations are inefficient, and high skills are required for operators, which is likely to cause quality fluctuations due to fatigue. Although some jigs attempt to optimize the installation path through a guiding structure, they still cannot solve the problem of the consistency of multi-pin synchronous force application, and have insufficient adaptability in complex arrangements or high-density installation scenarios. Therefore, there is an urgent need for a solution that can achieve multi-pin synchronous precise installation, uniform force application, and strong adaptability to improve production efficiency and product quality.

Specific embodiments

[0034] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] As Figures 1-4As shown in the figure, the present invention discloses a semi-automatic installation fixture for connector Pin pins, which includes a fixing plate 2 and a pressing plate 1 at a certain distance away from the fixing plate 2. The pressing plate 1 and the fixing plate 2 are corresponding up and down and have the same outer shape. Both are an approximate rectangular block extending a smaller rectangular block to both sides, and a first installation mechanism 3 is provided in each of the two smaller rectangular blocks on both sides and they are symmetrical to each other. The first installation mechanism 3 passes through the pressing plate 1 and the fixing plate 2 from top to bottom in sequence. The first installation mechanism 3 includes a pushing component 31 fixed on the pressing plate 1 and an installation block 32 fixed at the bottom of the fixing plate 2. The pushing component 31 includes a fixing block 311 fixed on the top of the pressing plate 1 and several thimble 312 fixedly connected in the fixing block 311. The fixing block 311 and the installation block are both rectangular blocks and are fixed by screws. Several thimble 312 extend downward from the fixing block 311 through the pressing plate 1 and the fixing plate 2 to the installation block 32. A sliding position 321 penetrating through the installation block 32 up and down and several pin pins 33 that can slide up and down in the sliding position 321 are provided in the installation block 32. Several thimble 312 extend to the sliding position 321 and correspond to several pin pins 33 one by one. At the same time, the number of thimble 312 and pin pins in one first installation mechanism 3 is two rows, with 6 in each row. And the semi-automatic installation fixture for connector Pin pins has two first installation mechanisms, that is, 24 pin pins can be installed at one time, 12 on each side.

[0036] Among them, when using the semi-automatic installation fixture for the connector Pin pins, first, manually or by machine, flip the semi-automatic installation fixture for the connector Pin pins so that the pressing plate 1 is at the bottom and the fixing plate 2 is at the top. Insert two rows of the Pin pins into the sliding positions 321 in the mounting block 32, and then flip the semi-automatic installation fixture for the connector Pin pins back to its original position. Immediately afterwards, align the semi-automatic installation fixture for the connector Pin pins with the installation holes corresponding to the Pin pins in the pin installation device. At this time, manually or by machine, move the pressing plate 1 closer to the fixing plate 2 to drive the ejector pin 312 to slide on the sliding position 321 and simultaneously eject the Pin pins into the holes in the pin installation device to complete the installation. In the existing technologies on the market, when installing Pin pins, it is usually necessary for workers to install the Pin pins into the corresponding installation holes one by one. This installation method has several drawbacks. For example, when workers install the Pin pins, they cannot ensure that the installation force is absolutely vertical. If the direction of the installation force deviates greatly from the installation hole, it is easy to cause the Pin pins to bend. Another example is that when installing manually, it is impossible to ensure that the installation force for each Pin pin is the same. If some have a large installation force and some have a small installation force, it is easy to make the multiple Pin pins uneven after installation on the pin installation device. To solve the above problems, through the mounting block 32 in the semi-automatic installation fixture structure of the connector Pin pins in this application, the Pin pins can correspond one by one to the installation holes in the pin installation device, avoiding deviation between the installation direction and the installation hole. At the same time, when the pressing plate 1 approaches the fixing plate 2, it drives the ejector pin 312 to use a single force to eject several Pin pins simultaneously, ensuring that each Pin pin receives the same thrust and avoiding unevenness. Moreover, this operation process is very simple and labor-saving, and can be efficiently completed with only manual or simple machine devices. In another embodiment, the several sliding positions 321 in the mounting block 32 can be changed arbitrarily according to the different numbers of Pin pins in different devices, not limited to the arrangement of two rows with 6 Pin pins in each row. In another embodiment, the fixed block 311 in the pushing member 31 can be not provided, and the ejector pin 312 can be directly fixedly connected to the pressing plate 1, and the same effect can be achieved. In another embodiment, the ejector pin 312 and the Pin pin 33 in the mounting block 32 do not need to be arranged in one-to-one correspondence. Instead, a pushing plate can be added in the mounting block 32, and one or more ejector pins 312 push the pushing plate to eject the Pin pins, and the same effect can be achieved.

[0037] Such as Figures 5-6As shown in the figure, specifically, in an embodiment of the present invention, the mounting block 32 is provided with a plurality of first screw holes 322 communicating with the sliding positions 321. The number of the first screw holes 322 is two rows, with 6 in each row. On both sides of the mounting block 32, they correspond to the pin pins 33 in each row one by one. A magnetic column 323 is arranged in the first screw hole 322 and magnetically attracts the pin pin 33 on the sliding position 321. This structural design enables the magnetic column 323 to adsorb the pin pin 33 when the pin pin 33 is inserted into the sliding position 321 in the mounting block 32, avoiding the pin pin 33 falling off from the mounting block 32 when the connector pin semi-automatic installation jig is flipped. When the ejector pin 312 ejects the pin pin 33, the pin pin 33 slides in the sliding position 321 and breaks away from the adsorption of the magnetic column 323. In another embodiment, the number of the plurality of first screw holes 322 in the mounting block 32 does not correspond to the sliding positions 321 one by one. Instead, two rows of connected hollow spaces are dug on both sides of the mounting block 32, and a bar magnet is placed in the hollow space, which can also achieve the above effect. In another embodiment, instead of using a magnet to adsorb the pin pin 33, a clamping groove is arranged in the sliding position 321, so that the pin pin 33 is clamped in the sliding position 321, which can also achieve the above effect.

[0038] As Figures 7-8 shown in the figure, specifically, in an embodiment of the present invention, 6 elastic members 5 and an elastic member cavity 51 for placing the elastic members 5 are arranged between the pressing plate 1 and the fixing plate 2. The elastic member cavity 51 is arranged at the bottom of the pressing plate 1 and the top of the fixing plate 2. One elastic member 5 is sandwiched between the upper and lower elastic member cavities 51. This structural design of the elastic member 5 enables the connector pin semi-automatic installation jig to be reset by the 6 elastic members 5 after the pressing plate 1 approaches the fixing plate 2 during installation. The design of the elastic member cavity 51 enables the elastic member 5 to be firmly fixed on the pressing plate 1 and the fixing plate 2 when being compressed and elastically reset, avoiding position deviation. In another embodiment, the elastic member cavity 51 corresponding to the elastic member 5 is not arranged on the pressing plate 1 and the fixing plate 2. Instead, the upper and lower ends of the elastic member 5 are fixed to the bottom of the pressing plate 1 and the top of the fixing plate 2, which can also achieve the above effect. In another embodiment, the pressing plate 1 is not reset by an elastic member device, but by hydraulic rebound or manual reset, which can also achieve the above effect.

[0039] As Figures 9-10As shown in the figure, further, the pressing plate 1 is provided with 4 limiting posts 11, which are respectively arranged at the four corners of the larger rectangular block in the middle of the pressing plate 1. The limiting posts 11 are composed of two cylinders with different diameters up and down, including a limiting post upper part 111 arranged at the top of the pressing plate 1 and a limiting post lower part 112 extending downward through the pressing plate 1 and the fixing plate 2 in sequence. Among them, the diameter of the limiting post upper part 111 is larger than that of the limiting post lower part 112. A third screw hole 23 is provided on the side of the fixing plate 2 and communicates with the internal limiting post lower part 112. A bolt is arranged in the third screw hole 23 to fixedly connect the limiting post lower part 112 in the fixing plate 2. The above structural design enables the pressing plate 1 to form a clamping connection through the limiting post upper part 111 when reset under the action of the elastic member 5, achieving a limiting effect. In another embodiment, the limiting post upper part 111 of the limiting post 11 is arranged at the bottom of the fixing plate 2, and the limiting post lower part 112 is fixed in the pressing plate 1. When resetting, the fixing plate 2 is separated from the pressing plate 1 to form a clamping connection, and the above-mentioned limiting effect can also be achieved.

[0040] As Figure 11 shown in the figure, specifically, in an embodiment of the present invention, the fixing plate 2 is provided with four positioning posts 21 that penetrate through the fixing plate 2 and extend downward for a certain distance. The positioning posts 21 are cylinders, with two arranged on each side of the fixing plate 2 and symmetrically arranged. And on the pin installation device, there are positioning holes corresponding to the positioning posts 21. The structural design of the positioning posts 21 enables the pin 33 to be easily aligned with the installation hole without deliberately aligning the pin and the installation hole when installing the pin 33. Only by aligning the positioning posts 21 and the positioning holes, the alignment of the pin and the installation hole can be realized, and the operation is very simple. In another embodiment, the positioning posts 21 do not penetrate through the fixing plate 2, but are fixed outside the fixing plate 2, and the above effect can also be achieved.

[0041] As Figure 11 shown in the figure, further, the positioning post 21 is provided with a clamping groove 211. The clamping groove 211 is arranged inside the fixing plate 2, and its shape is an annular groove with a diameter smaller than that of the positioning post 21. A second screw hole 22 communicating with the clamping groove 211 is provided on the side of the fixing plate 2. A clamping post 221 is arranged in the second screw hole 22 and extends into the clamping groove 211. This structural design enables the positioning post 21 to be fixedly connected to the fixing plate 2. In another embodiment, the clamping groove 211 is not provided, but the positioning post 21 is fixed to the fixing plate 2 by welding or bonding, and the above effect can also be achieved.

[0042] As Figure 11As shown in the figure, further, the positioning post 21 extends upward through the pressing plate 1. A sliding post 12 sleeved on the peripheral wall of the positioning post 21 is arranged between the pressing plate 1 and the positioning post 21. The sliding post 12 is a hollow cylinder. The outer side of the sliding post is fixedly connected inside the pressing plate 1, and the inner side is in direct contact with the positioning post 21. When the pressing plate 1 approaches the fixing plate 2, the positioning post 21 fixed on the fixing plate 2 does not move, and the pressing plate 1 and the sliding post 12 move downward relative to the positioning post. This structural design enables the moving track of the pressing plate 1 approaching the fixing plate not to deviate, playing a guiding role. And this structural design of the sliding post 12 replaces the direct contact between the pressing plate 1 and the positioning post 21, reducing the wear of the pressing plate 1. At the same time, compared with the relative movement when the pressing plate 1 contacts the positioning post 21, the sliding post 12 will be smoother and the operation will be more labor-saving.

[0043] As Figures 12-13 shown, specifically, in an embodiment of the present invention, second mounting mechanisms 4 are arranged on both sides of the first mounting mechanism 3. The second mounting mechanism 4 includes a pushing post 41 fixed on the pressing plate 1, a mounting post 42 fixed on the fixing plate 2, and a nut 43 arranged in the mounting post 42. A through hole penetrating up and down is arranged in the mounting post 42. The pushing post 41 extends downward into the mounting post 42 and can slide up and down and corresponds to the nut 43. When the pressing plate 1 approaches the fixing plate 2, it drives the pushing post 41 to slide in the mounting post 42 and pushes out the nut 43 to complete the installation. In another embodiment, the nut 43 in the mounting post 42 can be replaced with other parts, such as a bolt, and it is not necessary to be limited to the nut 43.

[0044] As Figures 12-13 shown, further, inside the mounting post 42, the diameter of a part of the through hole for placing the nut 43 is larger than that of other parts of the through hole, and the diameter of this through hole is slightly smaller than the diameter of the nut 43. This structural design enables the nut 43 to be clamped in the mounting post 42. When in use, the connector Pin needle semi-automatic installation jig is flipped and inserted into the pin needle 33 and the nut 43, and the nut 43 is clamped in the mounting post 42. In another embodiment, a threaded hole communicated with the through hole is arranged on one side of the mounting post 42, and a magnetic post is arranged to be magnetically attracted to the nut 43 in the through hole, and the same similar clamping effect can be achieved.

[0045] As Figure 1As shown in the figure, specifically, in an embodiment of the present invention, a handle 13 fixed to the top of the pressing plate 1 is provided on the pressing plate 1. The handle 13 includes two fixed points, which are respectively arranged at the junctions of two smaller rectangular blocks and a larger rectangular block in the semi-automatic installation jig for the connector Pin pins, that is, the handle 13 is arranged on the central axis passing through all the installation mechanisms. This structural design enables the same installation force to be applied to the first installation mechanism 3 and the second installation mechanism 4 on both sides during manual or machine (such as a robotic arm) clamping and picking operations, ensuring the consistency of the installation effect of the pin 33 in the installation hole 61 and avoiding unevenness. At the same time, it also makes the operation process of the semi-automatic installation jig for the connector Pin pins more convenient and efficient during manual picking and placing or robotic clamping and picking. In another embodiment, the handle 13 is set to be flipped by 90 degrees, and the same effect can be achieved.

[0046] As Figure 14 shown, the present invention also provides a pin installation device, which includes the semi-automatic installation jig for the connector Pin pins and also includes a machine tool 6. An installation position 64 corresponding to the semi-automatic installation jig for the connector Pin pins is provided on the machine tool 6. First installation holes 61, second installation holes 62, and positioning holes 63 corresponding to the pin 33, the installation post 42, and the positioning post 21 respectively are provided in the installation position 64.

[0047] The working principle of the present invention is described in detail as follows:

[0048] The working process of the present invention is divided into three stages: pre-installation stage: flip the semi-automatic installation jig for the connector Pin pins so that the pressing plate 1 faces downwards, insert the pins 33 one by one into the sliding positions 321 of the installation block 32, and the magnetic posts 323 fix the pins 33 by magnetic adsorption to prevent them from falling off. After flipping the jig back to its original position, the positioning post 21 is aligned with the positioning hole 63 of the pin installation device to achieve rapid and accurate focusing; force application and installation stage: the operator holds the handle 13 of the pressing plate 1 and applies a downward force to make the pressing plate 1 approach the fixed plate 2, driving the ejector pins 312 to move downward along the sliding positions 321. After the ejector pins 312 come into contact with the pins 33 one by one, a plurality of pins 33 are synchronously ejected by a uniform thrust and vertically inserted into the first installation holes 61 of the pin installation device; reset stage: after releasing the pressing plate 1, the elastic action of the elastic member 5 pushes the pressing plate 1 back to its initial position. The cooperation between the limit post 11 and the sliding post 12 ensures an accurate reset trajectory and avoids deviation. During the whole process, the rigid connection between the pressing plate 1 and the fixed plate 2, the synchronous movement of the ejector pins 312, and the coordinated action of the guiding structure jointly ensure the high precision and consistency of the installation.

[0049] The innovation of the present invention lies in: through the linkage design of the pressure plate and the fixed plate, combined with the one-to-one correspondence between the ejector pins and the sliding positions, it ensures that the force directions of multiple pin needles are completely perpendicular during the installation process, eliminating the risk of direction deviation in manual operation; the overall downward pressing action of the pressure plate acts on all pin needles simultaneously through the ejector pins, realizing synchronous ejection of multiple needles, and the thrust borne by each pin needle is the same, avoiding installation height differences caused by uneven force application; the modular design of the sliding positions in the installation block supports flexible adjustment of the number and arrangement of pin needles, and can adapt to different installation requirements, significantly improving the versatility of the jig; the combination of the magnetic attraction structure and the elastic part reset system not only ensures the stability during the pre-installation stage of the pin needles, but also realizes rapid reset after the jig operation, improving the continuous operation efficiency; the core advantage of the present invention is to transform the randomness of manual operation into the controllability of the mechanical structure, fundamentally solving the quality fluctuation problem of the traditional process, while taking into account efficiency and flexibility.

[0050] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
