In addition, the heating process of the terminal components before brazing may involve complex operations and the mechanism is not simple and practical enough. Utility Model Content

[0003] One of the purposes of this application is to provide a novel brazing fixture to solve the aforementioned technical problems.

[0004] To achieve the above-mentioned objectives, the technical solution adopted in this application is as follows:

[0005] This application provides a novel brazing fixture, comprising:

[0006] The feed guide rail is used to transport brazed parts;

[0007] The upper ceramic pressure block is located above the feed guide rail;

[0008] The bottom-perforated ceramic block is located below the feed guide rail;

[0009] An integrated limiting and separating pusher is located on one side of the lower-opening ceramic block and is used to separate and limit the brazed parts on the feed guide rail;

[0010] A floating cylinder is located below the lower perforated ceramic block. The floating cylinder is used to drive the lower ceramic lifting block through the lower perforated ceramic block to lift the brazing part until it comes into contact with the upper ceramic pressing block for compression, so that it can be induction heated by the heating coil.

[0011] In some embodiments, the top end of the upper ceramic pressure block is connected to a movable shaft via a transition round aluminum block. A first spring element is sleeved on the movable shaft. The top end of the movable shaft is also provided with an upper shaft movable limit block. The movable shaft is also connected to a transition block, and the transition block is connected to a support rod.

[0012] In some embodiments, the novel brazing fixture further includes a rear receiving inclined guide rail for receiving the brazed parts after brazing.

[0019] Compared with the prior art, the beneficial effects of the embodiments of this application are:

[0020] This application provides a novel brazing fixture. The workpiece to be brazed is placed on the feed guide rail and pushed onto the lower perforated ceramic block by a power source from other automated equipment or manually. An integrated limiting and separating pusher cutter separates and limits the workpiece, and then a floating cylinder pushes it upwards. Simultaneously, an upper ceramic pressure block presses the workpiece and raises it to a heating coil for induction heating (using a separate heating device). After heating and brazing are completed, the floating cylinder descends, the integrated limiting and separating pusher cutter retracts, and the workpiece enters the rear receiving inclined guide rail, completing one cycle of part processing. This novel brazing fixture offers advantages such as high bonding strength and resistance to separation in the brazed parts, meeting the pull-out force requirements of product parts. It also boasts significant low-cost advantages and can be used in the processing of positive and negative electrode parts for the top cover of new energy lithium batteries. Before being heated, the workpiece is kept away from the induction heating source and rises from the fixture into the heating source. The mechanism is simple and practical.

[0031] To illustrate the technical solution described in this application, specific embodiments are provided below.

[0032] Please see Figures 1 to 4As shown, this application provides a novel brazing fixture, comprising: a feed guide rail 17 for conveying brazing workpieces 14; an upper ceramic pressure block 13 located above the feed guide rail 17; a lower perforated ceramic block 15 located below the feed guide rail 17; an integrated limiting and separating pusher 25 located on one side of the lower perforated ceramic block 15 for separating and limiting the brazing workpieces 14 on the feed guide rail 17; and a floating cylinder 21 located below the lower perforated ceramic block 15, the floating cylinder 21 driving the lower ceramic lifting block 19 to pass through the lower perforated ceramic block 15 to lift the brazing workpieces 14 until they abut against the upper ceramic pressure block 13 for pressing, so as to be inductively heated by a heating coil.

[0033] As an example, the brazed component 14 includes an upper aluminum block 141 and a lower copper plate 142, which are brazed together.

[0034] In some embodiments, the top end of the upper ceramic pressure block 13 is connected to a movable shaft 30 via a transition round aluminum block 29. A first spring element is sleeved on the movable shaft 30, and the top end of the movable shaft 30 is also provided with an upper shaft movable limit block 32. The movable shaft 30 is also connected to a transition block 11, and the transition block 11 is connected to a support rod 12. The first spring element is used to assist the upper ceramic pressure block 13 in pressing the brazed part 14 without damaging it.

[0035] In some embodiments, the novel brazing fixture further includes a rear receiving inclined guide rail 28 for receiving the brazed parts 14 after brazing.

[0036] In some embodiments, the feed guide 17 is disposed on the first bracket 18, and the first bracket 18 is disposed on the base 23.

[0037] In some embodiments, the lower ceramic lifting block 19 is connected to the floating cylinder 21 via an adapter bracket 20.

[0038] In some embodiments, the floating cylinder 21 is mounted on the base 23 via a cylinder bracket 22.
