Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a passive clamping fixture and conveying device for tubular packaging. Background Technology

[0002] Tubular packaging, also known as rod packaging, is a packaging method used for electronic components. It involves securely and orderly encapsulating components within a rigid tube using a linear arrangement. The tubular packaging process typically requires multiple steps, including magnetic rod loading, wire winding, and soldering. Existing production lines generally use trays as the initial loading carrier, with dedicated positioning fixtures at each corresponding workstation. A transport mechanism repeatedly transfers the workpiece between the tray and different fixtures. Because the workpiece needs to be repeatedly positioned on different fixtures, cumulative errors are easily introduced, making it difficult to guarantee the consistency and accuracy of the workpiece's positioning throughout the entire processing flow. Each workstation requires an independent positioning fixture and transport mechanism, resulting in a complex system structure, large space occupation, and significantly increased equipment costs. It also creates considerable difficulties for subsequent equipment maintenance and process adjustments. Utility Model Content

[0003] The purpose of this invention is to solve the problems in the background technology and provide a passive clamping fixture and conveying device for tubular packaging, which can be matched with multiple processing equipment in the tubular packaging chip production process, reduce system complexity and size, and reduce equipment cost and maintenance difficulty of tubular packaging chips.

[0004] To achieve the above objectives, one aspect of the present invention provides a passive clamping fixture for tubular packaging, including a base and a clamping mechanism disposed on the base.

[0005] The clamping mechanism includes a gripper body, one end of which is slidably fitted with a pair of toggle joints, and the other end of which is fitted with a pressure cap that receives external force and drives the toggle joints to move closer or further apart in parallel motion. When no external force is applied, the toggle joints remain in a normally closed state. Each toggle joint has a chuck assembly for gripping a magnetic rod at its end. A guide platform is provided between the two chuck assemblies and is fixed to the base. Its top surface is used to guide the wire end of the magnetic rod. A wire hanging post is also provided on the base. The position of the wire hanging post corresponds to the guide platform and is used to cooperate with the guide platform to fix the wire end.

[0006] Furthermore, the pressure cap is mounted on one end of the gripper body via a connecting rod, and a thrust spring is provided between the pressure cap and the gripper body; a linear guide rail is provided at the other end of the gripper body, and a slider is installed in the linear guide rail, with the toggle fixedly connected to the slider; a lever structure is provided inside the gripper body to connect the connecting rod and the slider.

[0007] Furthermore, the front end of the chuck assembly consists of a pair of cantilevered claws mounted opposite each other, forming a circumferential structure, with the guide platform positioned at the center of the circumferential structure.

[0008] Furthermore, the two cantilever claws have horizontally opened mounting slots on their opposite sides. These mounting slots are used to clamp the magnetic rod and suspend one end of the magnetic rod in the air.

[0009] Furthermore, the base is U-shaped, with a crossbeam in the central groove, and the guide platform is located in the middle of the crossbeam, with a preset distance between it and the chuck assembly.

[0010] Furthermore, the height of the top surface of the guide table corresponds to the height of the mounting groove, and a guide pin is installed on the top surface for guiding the wire end.

[0011] Furthermore, the top surface of the guide platform is rectangular, and there are two guide pins, which are staggered at the two apex corners of the top surface.

[0012] Furthermore, the cantilever claw head is a detachable structure, equipped with positioning holes and bolt mounting holes.

[0013] Furthermore, there are four hanging posts, which are respectively set on both sides of the base groove and are spaced apart from the clamp assembly.

[0014] On the other hand, the present invention provides a conveying device, including a conveyor belt on which a passive clamping fixture for tubular packaging, any one of the above-mentioned claims, is mounted.

[0015] Compared to existing technologies, the advantages of this invention are: the normally closed clamping mechanism prevents the magnetic rod from falling off, improving the reliability and safety of the equipment. By placing the guide platform between the grippers and installing hanging posts on the base, the passive clamping fixture for tubular packaging provided by this invention can directly interface with the feeding mechanism, winding mechanism, and wafer bonding mechanism to complete operations such as magnetic rod feeding, winding, and wafer bonding. This reduces the number of positioning and handling mechanisms in the entire production line, simplifying the system structure, reducing space occupation, lowering equipment costs, and facilitating subsequent equipment maintenance and process adjustments.

[0022] One embodiment of this utility model provides a passive clamping fixture for tubular packaging, such as... Figure 1 The diagram shown is a schematic diagram of the passive clamping fixture for tubular packaging in this embodiment. The passive clamping fixture for tubular packaging in this embodiment includes a base 1 and a clamping mechanism 2 disposed on the base 1.

[0023] The base 1 is used to install and fix other components and is connected to the transmission device so that the fixture can move at each station. The clamping mechanism 2 is used to clamp the magnetic rod 3.

[0024] like Figure 2 The diagram shows the structure of the clamping mechanism 2. The clamping mechanism 2 includes a jaw body 21. A pair of elbow joints 22 are slidably mounted on one end of the jaw body 21, and a pressure cap 23 is mounted on the other end. When the pressure cap 23 receives an external force, it drives the elbow joints 22 to move parallel away from each other. When there is no external force, the elbow joints 22 remain in a normally closed state. Each elbow joint 22 has a clamping head assembly 24 for clamping the magnetic rod 3 mounted on its end. A guide platform 4 is provided between the two clamping head assemblies 24. The guide platform 4 is fixed on the base 1, and its top surface is used to guide the wire end 5 of the magnetic rod 3. A wire hanging post 6 is also provided on the base 1. The position of the wire hanging post 6 corresponds to the guide platform 4 and is used to cooperate with the guide platform 4 to fix the wire end 5.

[0025] In this embodiment, the normally closed state can be a pressure-depressurized clamping state, achieved through an elastic element. A cylinder can be installed at the loading / unloading position to apply external force to the pressure cap 23, causing the elbows 22 to move away from each other, facilitating loading / unloading operations. During transportation and other workstations, the clamping mechanism 2 remains clamped, improving transportation and processing safety. The chuck assembly 24 in this embodiment is replaceable, allowing it to accommodate magnetic rods 3 of different sizes, thus broadening the application range of the passive clamping fixture for tubular packaging. When winding the magnetic rod 3, the wire end 5 needs to be processed. The guide table 4 not only supports the enameled wire vertically but also guides it, fixing the wire along a preset path, facilitating subsequent chip soldering and other operations, thereby reducing the use of positioning components in each step.

[0026] The hanging post 6 is mainly used to fix the enameled wire during the winding process and assist the winding mechanism in winding. During the movement of the fixture, it cooperates with the guide table 4 to temporarily hang and fix the wire end 5 of the enameled wire that has been guided, preventing it from slipping off the guide table 4 and ensuring the reliability of positioning. The height and position of the hanging post 6 can be set according to the guide table 4, and a groove structure for locking the wire end 5 can be set on it.

[0027] In this embodiment, the pressure cap 23 is installed at one end of the gripper body 21 via a connecting rod, and a thrust spring 25 is provided between the pressure cap 23 and the gripper body 21; a linear guide rail 26 is provided at the other end of the gripper body 21, a slider 27 is installed in the linear guide rail 26, and the toggle 22 is fixedly connected to the slider 27; a lever structure is provided inside the gripper body 21 for connecting the connecting rod and the slider 27.

[0028] When an external force is applied to the pressure cap 23, the pressure is transmitted to the lever structure in the gripper body 21 via a connecting rod. The lever structure pushes the slider 27 to move along the linear guide rail 26, causing the two toggle joints 22 to move away from each other, thereby opening the chuck assembly 24. After the external force is removed, the thrust spring 25 pushes the pressure cap 23 back to its original position, and then, via the connecting rod, drives the entire mechanism back to the clamping state. This embodiment improves the clamping accuracy and stability through the linear guide rail 26, making it suitable for precision machining equipment and improving product precision.

[0029] In this embodiment, the front end of the chuck assembly 24 consists of a pair of cantilever claws 28 mounted opposite each other, forming a ring-shaped structure, and the guide platform 4 is located at the center of the ring-shaped structure.

[0030] Among them, the cantilever claw head 28 can extend out of the base 1 to facilitate winding and other processes. The two cantilever claw heads 28 can be "L" shaped to form an encircling structure, which can provide an installation position for the guide table 4 and also provide clearance space. The chip welding process is carried out between the cantilever claw head 28 and the guide table 4, which improves the practicality of this embodiment.

[0031] In this embodiment, the two cantilever claws 28 have horizontally opened mounting grooves on opposite sides. The mounting grooves are used to clamp the magnetic rod 3 and make one end of the magnetic rod 3 suspend in the air.

[0032] The mounting groove can be designed according to the shape of the magnetic rod 3, preferably with a triangular cross-section, which can provide a stable clamping force for the rod-shaped magnetic rod 3 and maintain the stability of the magnetic rod 3 during transportation and processing. The mounting groove clamps one end of the magnetic rod 3, leaving the other end of the magnetic rod 3 protruding and suspended in the air, which facilitates operations such as winding.

[0033] like Figure 3 The diagram shown is a schematic diagram of the base structure in this embodiment. In this embodiment, the base 1 is U-shaped, with a crossbeam provided in the central groove. The guide platform 4 is located in the middle of the crossbeam and has a preset distance between it and the clamp assembly 24.

[0034] After the magnetic rod 3 is wound, the enameled wire will have a fixed posture between the magnetic rod 3 and the guide table 4. The base 1 is set in a "U" shape, and the guide table 4 is set through the crossbeam. A space can be opened at the bottom of the base 1 to facilitate the setting of the chip mounting and soldering mechanism that docks with the enameled wire. Preferably, the chip soldering mechanism may include a mounting platform that can move up and down between the magnetic rod 3 and the guide table 4. The chip is placed on the mounting platform so that the solder joint of the chip docks with the enameled wire and completes the soldering process.

[0035] In this embodiment, the height of the top surface of the guide table 4 corresponds to the height of the mounting groove, and a guide pin 41 is installed on the top surface for guiding the wire end 5.

[0036] The top surface of the guide stage 4 is at a height corresponding to the height of the mounting groove, which effectively keeps the enameled wire between the magnetic rod 3 and the guide stage 4 horizontal, facilitating docking with the chip. There are generally two enameled wires, which are guided by the guide pin 41 to ensure they are parallel and correspond to the solder points on the chip.

[0037] In this embodiment, the top surface of the guide platform 4 is rectangular, and there are two guide pins 41, which are staggered at the two top corners of the top surface.

[0038] The spacing between solder points on the chip is generally small, and the corresponding spacing between the enameled wires is also small. By staggering the guide pins 11 at the two apex corners, it is easy to position the enameled wires and prevent misalignment.

[0039] In this embodiment, the cantilever claw head 28 is a detachable structure, and is provided with positioning holes and bolt mounting holes.

[0040] Among them, the cantilever claw head 28 can be disassembled and replaced to clamp magnetic rods 3 of different sizes, thereby improving the applicability of passive clamping fixtures used for tubular packaging.

[0041] In this embodiment, there are four hanging posts 6, which are respectively arranged on both sides of the groove of the base 1, and are spaced apart from the clamp assembly 24.

[0042] The hanging post 6 is mounted on the base 1, which does not affect the opening and closing of the clamping assembly 24 and can improve the stability of clamping. Preferably, two hanging posts 6 can be provided on each side of the groove in the base 1.

[0043] like Figure 4 The diagram shown is a structural schematic of a conveying device in another embodiment of the present invention. This embodiment provides a conveying device, including a conveyor belt 7, on which any of the passive clamping fixtures for tubular packaging described in the above embodiments is installed.

[0044] In this embodiment, the conveying device can be equipped with a track to further improve the positioning accuracy during the conveying process, thereby improving the coordination accuracy between the passive clamping fixture for tubular packaging and the processing equipment at each station. Preferably, a mounting plate can connect the transmission belt and the passive clamping fixture for tubular packaging, and multiple passive clamping fixtures for tubular packaging can be mounted side by side on one mounting plate, improving efficiency.

[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
