Abstract
Description
Technical Field
[0001] This utility model relates to a multi-channel electrode needle-like part gathering and assembly device, belonging to the field of precision assembly, and is suitable for the group assembly of small-sized spatial needle-like parts. Background Technology
[0002] The glass sealing body for pyrotechnic products consists of metal electrodes, a glass tube, and a metal shell. Before high-temperature sintering, these three parts need to be assembled together using tooling. Due to the small size of the shell cavity (diameter: Φ6~Φ8, depth: 12~15) and the small size and large aspect ratio of the electrodes (diameter: Φ0.9~Φ1; length: 19~20), each sealing body requires the assembly of 2 or 4 electrodes, necessitating high assembly precision. Currently, the assembly process is performed by operators using tweezers, which is inefficient and prone to omissions. Automating this process is challenging due to the confined space and precision requirements.
[0003] Traditional methods use a rotary table for partitioned assembly, with each partition responsible for loading, unloading, and assembly. It employs a single electrode and pin assembly mode. While this mechanism can effectively achieve assembly, the efficiency of single-needle assembly is low. Furthermore, in production modes with varied product structures and small batches, its versatility and interchangeability of universal interfaces are poor, making it unsuitable for the production modes of pyrotechnic products and multiple batches. Utility Model Content
[0004] The technical problem solved by this utility model is to overcome the shortcomings of the prior art and provide a multi-channel electrode needle part gathering and assembly device, which is adapted to gather discrete electrode needles into a fixed output port to meet the group assembly of multi-hole shafts, and solves the problems of high intensity, low efficiency and easy omission in manual assembly operations.
[0005] The technical solution of this utility model is: a multi-channel electrode needle-type part gathering and assembly device, comprising:
[0006] The outer casing has constraint holes, and the interior has a lower mounting plate.
[0007] The middle gathering block is fixedly connected to the lower mounting plate of the outer shell. The upper end is wider than the lower end, and the lower end is provided with a needle channel for gathering the needles that enter from the upper end and outputting them through the needle channel.
[0008] The guide block is fixedly connected to the bottom of the central gathering block and aligned with the electrode channel to form an electrode output guide channel;
[0009] The transition plate is fixedly connected above the central gathering block, with its lower end aligned with the electrode channel and its upper end connected to one end of the gathering tube.
[0010] The tube is connected to the transition plate through the constraint hole on the outer shell to form a channel for the electrode needle to fall and gather. One end is used to put in the electrode needle, and the other end is connected to the transition plate.
[0011] The press-fit module is fixedly connected to the housing and includes a press head and a press-fit cylinder for driving the press head to extend and retract; the press head is inserted into a retracting block, which acts on the end face of the electrode needle;
[0012] An isolation module, fixed to the outer casing, includes an isolation plate and a partition cylinder for driving the isolation plate to extend and retract; the isolation plate is inserted into the electrode output guide channel to form electrode outlet isolation.
[0013] Furthermore, before assembly, the pressure head retracts, the isolation plate extends, and the channel between the central gathering block and the guide block is blocked. After the electrode needle falls from the gathering tube, it relies on its own weight and friction with the inner wall of the gathering tube to pass through the transition plate and fall into the central gathering block. Under the constraint of the inner conical wall of the central gathering block, the electrode needle gathers and stands vertically in the electrode needle channel at the lower end of the central gathering block.
[0014] Furthermore, during assembly, the isolation plate retracts, and the electrode needles are assembled with the workpiece to be assembled through the electrode needle output guide channel. The pressure head moves a fixed distance to achieve reliable assembly of the grouped electrode needles.
[0015] Furthermore, the transition plate is provided with guide holes; the pressure head is inserted into the converging block through the guide holes on the transition plate.
[0016] Furthermore, the bottom of the outer shell is provided with a lower mounting interface; the central gathering block and the guide block are integrally fixedly connected to the lower mounting interface of the outer shell.
[0017] Furthermore, the outer casing has an upper mounting plate located above the lower mounting plate; the press-fit module is fixedly connected to the upper mounting plate.
[0018] Furthermore, the internal structure of the central gathering block is an oblique conical hole, the taper of which is adapted to the length of the electrode needle to ensure the falling of the electrode needle.
[0019] Furthermore, the number of electrode channels in the gathering block, guide block, and transition plate is increased according to the number of electrode needles to be gathered.
[0020] Furthermore, the inner diameter of the gathering tube is less than 80% of the length of the electrode needle, and is adjusted according to the length of the electrode needle to be assembled.
[0021] Furthermore, the vertical hole at the lower end of the conical hole of the converging block has a rounded transition with the conical hole, and the length of the vertical hole is not less than 30% and not more than 80% of the length of the electrode needle.
[0022] The advantages of this utility model compared with the prior art are as follows:
[0023] (1) This utility model uses a pipe to form a convergence channel, which gathers the relatively discrete electrode inputs into a small size range to a large extent. Then, a precision convergence structure is used to achieve precise positioning of the electrode, providing a solution for the efficient and automated assembly of this type of product. Compared with the existing single-needle single-assembly, it greatly improves the assembly efficiency.
[0024] (2) The structural fine adjustment of the guide block and the middle gathering block of this utility model can be adapted to the output of 2 or 4 pins with different pin spacings. This can be achieved by simply replacing the guide block and the middle gathering block, which can meet the production needs of multiple varieties and small batches of pyrotechnic glass sealing bodies.
[0025] (3) The front end of the converging pipe of this utility model can be directly connected to the vibratory plate used for electrode needle loading and unloading, which has good versatility. Attached Figure Description

[0031] The following description, in conjunction with the accompanying drawings, provides a more detailed account of a multi-channel electrode needle-type part gathering and assembly device according to an embodiment of this utility model. Figure 1 Specific implementation methods may include:
[0032] The outer casing 30 has constraint holes and a lower mounting plate inside.
[0033] The middle gathering block 50 is fixedly connected to the lower mounting plate of the outer shell 30. The upper end is wider than the lower end, and the lower end is provided with a needle channel for gathering the needles that enter from the upper end and outputting them through the needle channel.
[0034] The guide block 80 is fixedly connected to the bottom of the central gathering block 50 and aligned with the electrode channel to form an electrode output guide channel;
[0035] Transition plate 40 is fixedly connected above the middle gathering block 50, with its lower end aligned with the electrode channel and its upper end connected to one end of the gathering tube 20.
[0036] The gathering tube 20 is connected to the transition plate 40 through the constraint hole on the outer shell 30 to form a needle falling and gathering channel. One end is used to put in the needle, and the other end is connected to the transition plate 40.
[0037] The press-fit module 10 is fixedly connected to the housing 30 and includes a press head 12 and a press-fit cylinder 11 for driving the press head 12 to extend and retract; the press head 12 is inserted into the retracting block 50 and acts on the end face of the electrode needle.
[0038] The isolation module 90 is fixed on the outer shell 30 and includes an isolation plate 92 and a partition cylinder 91 for driving the isolation plate 92 to extend and retract; the isolation plate 92 is inserted into the electrode output guide channel to form electrode outlet isolation.
[0039] In the solutions provided by the embodiments of this utility model, such as Figure 1 As shown, a multi-channel electrode needle-type part gathering and assembly device includes an upper pressing mold 10, a pressing cylinder 11, a pressing head 12, a gathering tube 20, a housing 30, a transition plate 40, a middle gathering block 50, a screw 1 60, a screw 2 70, a guide block 80, an isolation module 90, a partition cylinder 91, an isolation plate 92, a screw 4 100, and a screw 5 110.
[0040] The guide block 80 is connected to the central gathering block 50 by two screws 70. The guide block 80 and the electrode channel on the central gathering block 50 are aligned to form a precise electrode output guide channel. The central gathering block 50 and the guide block 80 are fixed to the lower mounting interface of the outer shell 30 by two screws 60. The transition plate 40 and the central gathering block 50 are fastened together by two screws 100. The gathering tube 20 is connected to the transition plate 40 through the constraint hole on the outer shell 30 to form an electrode falling and gathering channel. The pressing module 10 is fastened to the upper mounting plate of the outer shell 30 by four screws 110. The pressing head 12 of the pressing module 10 is inserted into the central gathering block through the guide hole on the transition plate 40.

After the electrode needle falls from the gathering tube 20, it falls into the middle gathering block 50 after passing through the transition plate 40 by its own weight and friction with the inner wall of the gathering tube 20. The electrode needle is gathered under the constraint of the inner conical wall of the middle gathering block 50 and presents a vertical electrode needle channel at the lower end of the middle gathering block 50.
[0042] like Figure 3 During assembly, the isolation module 90 operates, and the isolation plate 92 retracts under the drive of the partition cylinder 91. The electrode needles are output through the guide block electrode needle outlet to complete the group assembly with the workpiece to be assembled. To ensure the reliability of the assembly, the pressing module 10 operates, and the pressing head 12 moves downward under the drive of the pressing cylinder 11. The pressing head 12 acts on the end face of the electrode needle and moves a fixed distance to achieve reliable assembly of the grouped electrode needles.
[0043] In one possible implementation, the internal structure of the central gathering block 50 is an oblique conical hole, the taper of which is adapted to the length of the electrode needle to ensure the falling of the electrode needle.
[0044] Furthermore, the number of electrode channels in the central gathering block 50, guide block 80, and transition plate 40 is increased according to the number of electrode needles to be gathered.
[0045] Optionally, the inner diameter of the gathering tube 20 is less than 80% of the length of the electrode needle, and is adjusted according to the length of the electrode needle to be assembled.
[0046] Optionally, the vertical hole at the lower end of the conical hole of the 50-inch converging block and the conical hole are rounded, and the length of the vertical hole is not less than 30% and not more than 80% of the length of the electrode needle.
