Description

Technical Field

[0001] This invention relates to the technical field of pin assembly equipment, and in particular to a multifunctional pin assembly device. Background Technology

[0002] A pin insertion machine is a key type of automated equipment in the electronics manufacturing industry. Its core function is to automatically, efficiently, and with high precision integrate and insert various connectors, pin headers, leads, or specific functional modules into target electronic components.

[0003] However, existing pin insertion equipment generally has significant limitations when facing diversified production needs. Especially when a single component needs to integrate pin modules of different specifications or spacings, existing pin insertion equipment requires operators to constantly change pin modules during component insertion. Each change means the equipment needs to stop operating, reload the different specifications of the pin modules, and switch programs. This process not only significantly increases downtime and reduces production efficiency, but also, due to the frequent switching involving manual operation or complex automated systems, may introduce calibration errors, affecting the insertion accuracy and consistency of the final product, thereby increasing production costs. Summary of the Invention

[0004] This application provides a multifunctional pin insertion device that can rationally select and assemble pin modules without interrupting power.

[0005] This application provides a multifunctional pin insertion device, which adopts the following technical solution: A multifunctional pin insertion device is disclosed for inserting pin modules into the interior of components. The pin module includes a strip-shaped clamping carrier and multiple pin units, comprising a base, a lifting feeding mechanism, a lateral feeding mechanism, a cutting device, a waste collection device, and a pushing assembly. An assembly platform is disposed at the top center of the base. The lifting feeding mechanism is symmetrically disposed on both sides of the assembly platform, and the lateral feeding mechanism is fixed to the movable end of the lifting feeding mechanism. The cutting device is fixed to the top of the assembly platform, and the waste collection device is located below the cutting device and fixedly connected to the assembly platform. The pushing assembly is disposed on the upper surface of the assembly platform for pushing the pin units into the interior of the components.

[0006] By adopting the above technical solution, and by setting up a combination of lifting and traversing feeding mechanisms, various different pin modules can be accurately transported to the assembly platform in two-dimensional space. This allows for the rational selection and assembly of pin modules without power interruption, which not only reduces manual intervention but also improves product production efficiency. Furthermore, the pin modules are separated using a cutting device, and the separated pin units are inserted into the components using a pushing component. The entire process is automated, from feeding to pin unit assembly to waste collection by the waste collection device, achieving automated operation.

[0007] Preferably, the lifting and feeding mechanism includes a mounting frame, a slide rail, a first electric push rod, and a lifting frame; the mounting frame is fixed to both sides of the base, the slide rail is fixed to the inner side of the mounting frame in the vertical direction, the output end of the first electric push rod is fixedly connected to the lifting frame, the lifting frame is slidably connected to the mounting frame through the slide rail, and the transverse feeding mechanism is fixed on the lifting frame.

[0008] By adopting the above technical solution, the lifting frame slides up and down on the slide rail through the first electric push rod until a pin module on the lifting frame corresponds to the assembly platform, realizing automatic, accurate, and rapid switching and positioning of pin modules of different specifications; it can meet the assembly needs of components with different pin pitches without frequent manual mold replacement or equipment adjustment, greatly improving the versatility and flexibility of the production line.

[0009] Preferably, the transverse feeding mechanism includes an upper buckle plate, a lower buckle plate, a drive motor, and a gear; the upper buckle plate and the lower buckle plate form a guide groove, the drive motor is fixed to the lower surface of the lower buckle plate, the gear is fixedly connected to the output end of the drive motor, and the gear meshes with the rack structure on the outside of the pin module.

[0010] By adopting the above technical solution, the guide groove formed between the upper and lower buckle plates provides a precise horizontal movement path for the pin module. With the help of gears meshing with the rack structure on the outside of the pin module, the rotational motion of the drive motor is converted into a precise horizontal linear motion of the pin module. This allows the pin module to move horizontally along the guide groove to the position of the designated assembly platform.

[0011] Preferably, the feeding assembly includes a third electric push rod and an assembly pressure plate; the output end of the third electric push rod is fixedly connected to the assembly pressure plate, the assembly pressure plate is located on one side of the component, and the pin unit is located between the assembly pressure plate and the component, and the pressure plate and the pin unit end of the pin module are arranged opposite to each other.

[0012] By adopting the above technical solution, the assembly pressure plate is driven by the third electric push rod, so that the assembly pressure plate is pushed into the component and the pin is inserted to realize the installation function of the pin.

[0013] Preferably, the cutting device includes a mounting bracket, which is installed on the upper surface of the assembly platform, and the mounting bracket is provided with a second electric push rod inside. The bottom output end of the second electric push rod is fixedly connected to a T-shaped pressure block, and two cutting blades are symmetrically arranged on the lower surface of the pressure block.

[0014] By adopting the above technical solution, the second electric push rod applies downward pressure to the pressure block until the two cutting blades pass through the gap between two adjacent pin units and cut the strip clamping carrier.

[0015] Preferably, the pressure block has a guide positioning plate inside, the guide positioning plate is connected to the mounting bracket by a spring, and the guide positioning plate is in contact with the upper surface of the pin module.

[0016] By adopting the above technical solution, when the pressure block moves downward, the bottom of the guide positioning plate is first positioned on the upper surface of the pin module. This not only serves to position and support multiple pin modules, but the spring setting also effectively buffers the pressure, preventing excessive pressure from damaging or breaking the pin module, thus protecting the integrity of the product and the yield rate.

[0017] Preferably, the pin module includes a strip-shaped clamping carrier and multiple pin units; the upper surface of the strip-shaped clamping carrier is provided with two rows of locking strips, the locking strips being support blocks with V-shaped or U-shaped openings, the openings being engaged and fixed with the outer wall of the pin unit.

[0018] By adopting the above technical solution, the V-shaped or U-shaped bayonet of the Y-shaped support block has a certain elasticity. When the pin is inserted into the bayonet, the pin will squeeze the two arms of the Y-shaped support block, causing them to undergo slight elastic deformation outward. Once the pin crosses the narrowest point of the bayonet, the Y-shaped support block will use the elastic recovery force of its material to re-contract, thereby tightly locking the pin.

[0019] Preferably, at least two sets of pin modules with different gaps are fixed at both ends of the lifting frame, and the different pin modules slide laterally along the lifting frame and are locked by a first electric push rod.

[0020] By adopting the above technical solution, pin modules with different gaps can be adjusted longitudinally, thereby enabling switching between different pin modules.

[0021] Preferably, the lifting feeding mechanism, the transverse feeding mechanism, the cutting device, and the pushing assembly are all electrically connected to the control system.

[0022] The above technical solution is used to drive the lifting and feeding mechanism, the transverse feeding mechanism, the cutting device, and the pushing assembly in a fully automatic control system.

[0023] Preferably, the top opening of the waste collection device is directly opposite the cutting device, and the bottom of the waste collection device is provided with a waste discharge channel.

[0024] By adopting the above technical solution, a waste collection device is used to guide the cut strip-shaped clamping carrier waste.

[0025] In summary, this application has the following beneficial effects: 1. By setting up a combination of lifting and traversing feeding mechanisms, various different pin modules are accurately transported to the assembly platform in two-dimensional space. The pin modules are separated and processed by a cutting device, and the separated pin units are inserted into the internal parts of the components by a pushing component. The whole process is automated, from feeding to pin units to waste collection by a waste collection device, reducing manual intervention.

[0026] 2. By setting up a combination of lifting and traversing feeding mechanisms, it is possible to accurately transport various different pin modules in two-dimensional space, which improves the flexibility and efficiency of feeding and meets the need to transport multiple pin units to the insertion position at the same time.

[0027] 3. The various mechanisms work closely together, with the lifting and feeding mechanism, the lateral feeding mechanism, the cutting device, and the pushing device cooperating with each other to ensure the accuracy and stability of the pin module during the conveying, cutting, and insertion process, thereby improving product quality.

[0028] 4. The entire device achieves automated pin module delivery, cutting, and insertion processes, reducing manual intervention, improving production efficiency, and lowering product defect rates.

[0029] 5. The waste collection device installed below the cutting device can collect the waste after cutting in a timely manner, keep the production environment clean, and avoid the impact of waste on the normal operation of the equipment. Attached Figure Description

[0031] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0032] This invention discloses a multifunctional pin insertion device for inserting a pin insertion module 2 into the interior of a component 1, such as... Figure 1 and Figure 2 As shown, the pin module 2 includes a strip-shaped clamping carrier 201 and multiple pin units 202, including a base 3, an assembly platform 4 is provided at the center of the base 3, and lifting and feeding mechanisms 5 are provided on both sides of the assembly platform 4 of the base 3. Each lifting and feeding mechanism 5 is provided with a transverse feeding mechanism 6 for horizontally conveying the pin module 2 to the assembly platform 4.

[0033] A cutting device 7 for cutting the strip clamping carrier 201 is fixedly installed on the top of the assembly platform 4 of the base 3. A waste collection device 8 is fixedly installed on the bottom of the assembly platform 4 of the base 3. The waste collection device 8 is located below the cutting device 7. A pushing component 9 is also provided on the upper surface of the assembly platform 4. The pushing component 9 is used to push and insert the pin unit 202 into the component 1.

[0034] It also includes a control system, and the lifting and feeding mechanism 5, the transverse feeding mechanism 6, the cutting device 7 and the pushing assembly 9 are all electrically connected to the control system.

[0035] like Figure 1 and Figure 2As shown, after the cutting device 7 cuts the strip clamping carrier 201, the cut strip clamping carrier 201 waste falls into the waste collection device 8 under the action of gravity. The bottom of the waste collection device 8 is provided with a waste discharge channel, and multiple pin units 202 are pushed in a direction closer to the component 1 by the pushing component 9, so as to insert multiple different pin units 202 into the same component 1; this is used to significantly improve the production speed of pin units 202, realize large-scale production, and far exceed the efficiency of manual operation; the automation of the whole process (feeding, cutting, insertion, waste collection) reduces the production cycle.

[0036] like Figure 2 As shown, specifically, the upper surface of the strip-shaped clamping carrier 201 is provided with two rows of clips, each clip consisting of several Y-shaped support blocks 203. The top of the Y-shaped support block 203 forms a V-shaped or U-shaped bayonet 204 that matches the pin unit 202, and the bayonet 204 is engaged with the pin unit 202.

[0037] like Figure 2 As shown, the "V" or "U" shaped latch 204 of the Y-shaped support block 203 has a certain elasticity; when the pin unit 202 is inserted into the latch 204, the pin unit 202 will squeeze the two arms of the Y-shaped support block 203, causing them to undergo slight elastic deformation outward; once the pin unit 202 crosses the narrowest point of the latch 204, the Y-shaped support block 203 will use the elastic recovery force of its material to re-contract, thereby tightly locking the pin unit 202.

[0038] like Figure 1 and Figure 3 As shown, in this embodiment, there are 4 sets of pin modules 2, and the 4 sets of pin modules 2 are all pin units 202 structures with different gaps. Each pair of pin modules 2 is fixed on the lifting and feeding mechanism 5. The lifting and feeding mechanism 5 includes two mounting brackets 501, which are fixed on both sides of the base 3. The mounting brackets 501 are provided with slide rails 504 and a first electric push rod 502. The output end of the first electric push rod 502 is connected to a lifting frame 503 for connecting two sets of pin modules 2. Through the first electric push rod 502, the lifting frame 503 slides up and down on the slide rail 504 until a pin module 2 on the lifting frame 503 corresponds to the assembly platform 4.

[0039] like Figure 1 and Figure 3As shown, the system has four sets of pin modules 2 with different gaps; this is like a tool library, storing a variety of tools suitable for different pin pitches; every two sets of pin modules 2 are fixed on a lifting frame 503; the lifting frame 503 is driven by a first electric push rod 502 to move up and down along the slide rail 504 on the mounting frame 501; when a pin module 2 with a specific gap is needed, the electric push rod will precisely control the movement of the lifting frame 503 to raise or lower the required set of pin modules 2 to a position that is fully aligned with the assembly platform 4; once aligned, this set of pin modules 2 can perform its pin unit 202 assembly task.

[0040] like Figure 1 and Figure 3 As shown, the system of the first electric push rod 502 and slide rail 504 enables automatic, precise, and rapid switching and positioning of pin modules 2 of different specifications; it can meet the assembly requirements of components with different pin pitches without the need for frequent manual mold changes or equipment adjustments, which greatly improves the versatility and flexibility of the production line; this is especially beneficial for production scenarios with multiple varieties, small batches, or frequent product switching.

[0041] like Figure 1 and Figure 3 As shown, the automatic switching and positioning of the pin module 2 is achieved through the first electric push rod 502, which replaces the traditional manual replacement and adjustment, significantly reducing production preparation time (line changeover time) and thus improving overall production efficiency and automation level.

[0042] like Figure 1 and Figure 3 As shown, the transverse feeding mechanism 6 is fixed on the lifting frame 503. Specifically, the transverse feeding mechanism 6 includes an upper buckle plate 601 and a lower buckle plate 602. A guide groove 603 for the pin insertion module 2 to pass through is formed between the upper buckle plate 601 and the lower buckle plate 602. A drive motor 604 is fixedly installed on the lower surface of the lower buckle plate 602. A gear 605 is connected to the output end of the drive motor 604. The gear 605 is meshed with multiple pin units 202 of the pin insertion module 2.

[0043] like Figure 1 and Figure 3As shown, the guide groove 603 formed between the upper buckle plate 601 and the lower buckle plate 602 provides a precise horizontal movement path for the pin module 2; this ensures the straightness and stability of the pin module 2 during the lateral movement, preventing deviation or shaking; the output end of the drive motor 604 is connected to the gear 605; the gear 605 is meshed with multiple pin units 202 of the pin module 2, which generally means that a rack structure is formed between the multiple pin units 202 on the pin module 2. When the drive motor 604 rotates, the rotational motion of the drive motor 604 is converted into a precise horizontal linear motion of the pin module 2 through the meshing of the gear 605 and the rack structure; this allows the pin module 2 to move horizontally along the guide groove 603 to the position of the designated assembly platform 4.

[0044] like Figure 1 and Figure 3 As shown, the horizontal guidance of the transverse feeding mechanism 6 is combined with the vertical positioning of the lifting feeding mechanism 5, and the transverse feeding mechanism 6 provides horizontal positioning capability; this enables the pin module 2 to achieve precise two-dimensional spatial positioning, greatly expanding its working range and adaptability, and can cope with more complex assembly tasks.

[0045] like Figure 4 As shown, the cutting device 7 includes a mounting bracket 701, which is mounted on the upper surface of the assembly platform. The mounting bracket 701 has a second electric push rod 702 inside. The bottom output end of the second electric push rod 702 is fixedly connected to a T-shaped pressure block 703. Two cutting blades 704 are symmetrically arranged on the lower surface of the pressure block 703. The second electric push rod 702 applies downward pressure to the pressure block 703 until the two cutting blades 704 pass through the gap between two adjacent pin units 202 and cut the strip clamping carrier 201.

[0046] like Figure 4 As shown, when the electric push rod drives the pressure block 703 to move downward, the blade passes through the gap and applies shearing or pressing force to the preset strip clamping carrier 201, thereby achieving the cutting action and separating or cutting it; the use of the second electric push rod 702 means that the cutting process can be automated or semi-automated, reducing the labor intensity and time of manual operation and significantly improving production efficiency.

[0047] like Figure 4 As shown, the pressure block 703 has a strip-shaped positioning hole 705 inside. The strip-shaped positioning hole 705 of the pressure block 703 has an L-shaped guide positioning plate 706 inside. The top of the guide positioning plate 706 passes through the strip-shaped positioning hole 705 and is connected to a spring 707. The bottom end of the spring 707 is connected to the top of the guide positioning plate 706, and the top of the spring 707 is connected to the mounting bracket 701.

[0048] like Figure 4 As shown, before the pressure block 703 moves downward to cut, the L-shaped guide positioning plate 706 located in its strip-shaped positioning hole 705 will first contact the upper surface of the pin unit 202; this means that the guide positioning plate 706 reaches and contacts the pin unit 202 earlier than the cutting blade 704; once the L-shaped guide positioning plate 706 contacts the pin unit 202, it plays a positioning and supporting role; it stably fixes multiple pin units 202 in the expected position, ensuring that they are in the expected position during subsequent cutting. No displacement or shaking will occur during the process; after the guide positioning plate 706 contacts and fixes the pin unit 202, the pressure block 703 will continue to move downward; since the guide positioning plate 706 has been blocked by the pin unit 202 and cannot continue to descend, the pressure block 703 will continue to press down relative to the guide positioning plate 706; at this time, the spring 707 is connected between the top of the guide positioning plate 706 and the mounting bracket 701, and it will be compressed due to the relative movement of the pressure block 703, thereby absorbing and buffering part of the downward impact force.

[0049] like Figure 4 As shown, the buffering effect of the spring 707 ensures that the pressure applied to the pin unit 202 increases gradually, rather than being a sudden rigid impact; this controlled pressure transmission helps ensure that the pin unit 202 is in a stable and protected state when the cutting blade 704 reaches its point of action, and that the blade can cut with appropriate force, avoiding bending, breaking or damage to the pin unit 202 due to excessive instantaneous pressure.

[0050] like Figure 5 As shown, the pusher assembly 9 includes a third electric push rod 901. The output end of the third electric push rod 901 is connected to an assembly pressure plate 902. The assembly pressure plate 902 is located on one side of the component 1, and the pin unit 202 is located between the assembly pressure plate 902 and the component 1. The assembly pressure plate 902 is driven by the third electric push rod 901, so that the assembly pressure plate 902 is pushed towards the inside of the component 1 and the pin unit 202 is inserted.

[0051] Working principle: The pin module 2, which contains multiple pin units 202, is accurately horizontally transported and positioned on the assembly platform 4 by the lifting feeding mechanism 5 and the transverse feeding mechanism 6 on both sides. This ensures that the pin module 2 can accurately enter the subsequent processing station.

[0052] The cutting device 7, located at the top of the assembly platform 4, operates on the positioned pin module 2. It cuts the strip-shaped clamping carrier 201 that connects multiple pin units 202 together. This step is crucial because it separates the pin unit 202 from its strip-shaped clamping carrier 201, making it ready for insertion.

[0053] After the cutting is completed, the pusher assembly 9 above the assembly platform 4 will simultaneously push the separated pin units 202 towards the component 1; these pin units 202 are precisely pushed into the interior of the component 1 to complete the pin unit 202 operation; the description mentions that multiple different pin units 202 can be inserted into the same component 1, which suggests that the device may have the ability to handle different types or configurations of pin units 202.

[0054] The cut strip-shaped clamping carrier 201 waste material falls directly into the waste collection device 8 located below the cutting device 7 under the action of gravity; this realizes the automatic separation and collection of waste material and keeps the work area clean.

[0055] The entire process is automated, from feeding to inserting the 202 single unit and then to waste collection, reducing human intervention.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
