Abstract
Description
Technical Field
[0001] This utility model belongs to the field of laser marking technology, specifically relating to a power module laser marking fixture. Background Technology
[0002] The fixture ensures the precise positioning of the power module during the laser marking process, making the marking position accurate and stable; this is crucial for power modules that require precise marking of specifications, parameters, company logos, and other information.
[0003] A power module laser marking fixture, disclosed in patent publication number CN222307717U, includes a fixture body comprising an integrally formed fixing part and a mounting part. A mounting part, perpendicular to the fixing part, is positioned directly above it. The mounting part is recessed downwards to form a limiting groove with an open top surface and two opposite sides. A deadbolt is vertically inserted into the limiting groove. At each of the four corners of one side of the limiting groove, an extension protrusion with a positioning groove is provided. A positioning post is installed in the positioning groove of each extension protrusion, and the four positioning posts match four positioning holes at the corners of the power module. A back plate is installed on the mounting part, supporting and limiting the rear end face of the deadbolt. A through threaded hole is provided in the middle of the back plate, into which a bolt is installed. By adjusting the relative position of the bolts, the deadbolt is tightened onto the fixture body.
[0004] When it is necessary to replace power modules with different models, the adjusting bolt needs to be turned to disengage the anti-fouling plate from the fixture body. This process is relatively cumbersome and affects production efficiency. In addition, the frequent use of the adjusting bolt may also cause it to wear or be damaged, which in turn affects the stability and service life of the fixture. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1
[0027] Please see Figures 1-6 This is the first embodiment of the present invention, which provides a power module laser marking fixture, including...
[0028] The top of the fixing base 2 is provided with symmetrically distributed fixing slots 21, thus realizing the opening of the fixing slots 21;
[0029] The anti-misalignment plate 3 is matched with the power module. The anti-misalignment plate 3 has holes 31 corresponding to the pins of the power module to prevent the power module from being placed in the wrong direction when it is marked. The anti-misalignment plate 3 can be inserted into the interior of two fixing slots 21 to increase the limitation of the anti-misalignment plate 3.
[0030] The stabilizing device includes a plug-in plate 32 located at the bottom of the anti-misalignment plate 3, which adds the plug-in plate 32; a plug-in slot 22 opened on the fixing base 2 for the plug-in plate 32 to be inserted, which adds the plug-in slot 22; a fixing plate 5 located on the inner side of the plug-in slot 22, which adds the fixing plate 5; and a stop plate 6 located on the side surface of the fixing plate 5 and abutting against the plug-in plate 32. When the anti-misalignment plate 3 is installed, the plug-in plate 32 is inserted into the plug-in slot 22, and the stop plate 6 is pressed against the plug-in plate 32, which improves the installation performance of the anti-misalignment plate 3; a telescopic spring 211 located on the fixing slot 21, which adds the telescopic spring 211; and a movable plate 7 located at one end of the telescopic spring 211, which allows the movable plate to be inserted. The addition of 7, with a connecting plate 8 installed at one end of the movable plate 7 and pressed against the anti-misalignment plate 3, allows the anti-misalignment plate 3 to be inserted into the fixing groove 21 and press against the connecting plate 8 during installation. When the connecting plate 8 is pressed, it causes the movable plate 7 to compress the telescopic spring 211. After the telescopic spring 211 is compressed, it returns to its original position, causing the movable plate 7 to move and the two connecting plates 8 to press against the anti-misalignment plate 3. When replacing the anti-misalignment plate 3, it can be removed by pulling it up. The anti-misalignment plate 3 is reinforced by a double fixing method of plug-in limitation and clamping, which improves the efficiency of replacing the anti-misalignment plate 3, ensures the accurate positioning of the power module during laser marking, meets the marking requirements of different types of power modules, and improves production efficiency and product quality.
[0031] In this embodiment, preferably, the connecting plate 8 and the movable plate 7 are connected by screws, so that the connecting plate 8 and the movable plate 7 are firmly spliced, and one end of the connecting plate 8 is inclined, making it more convenient for the anti-misalignment plate 3 to be inserted into the fixing slot 21.
[0032] In this embodiment, preferably, a positioning post 4 is installed on the fixed base 2 and matches the positioning hole of the power module. When the power module cannot match the anti-fool plate 3, the module cannot be fixed. The horizontal plate 1 is connected to the fixed base 2 by bolts, so that the horizontal plate 1 and the fixed base 2 are stably spliced.
[0033] In this embodiment, preferably, the positioning post 4 and the fixing seat 2 are connected by screws, so that the positioning post 4 and the fixing seat 2 are firmly fixed.
[0034] Example 2
[0035] Please see Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that:
[0036] It also includes a guide post 210 set on the fixed groove 21, which realizes the addition of the guide post 210, and a fixing ring 71 set on the side surface of the movable plate 7, which realizes the addition of the fixing ring 71. The guide post 210 passes through the fixing ring 71. The cooperation between the guide post 210 and the fixing ring 71 increases the stability of the movable plate 7 when it moves.
[0037] The abutment plate 6 has an inclined structure, which increases the convenience of inserting the plug plate 32. The side surface of the abutment plate 6 has a groove 61, which realizes the opening of the groove 61. The groove 61 has a screw 610 inside, and the screw 610 is screwed into the interior of the movable plate 7. The screw 610 is used to realize the stable splicing of the abutment plate 6 and the movable plate 7.
[0038] The working principle and usage process of this utility model are as follows: When in use, the positioning hole of the power module is placed into the positioning post 4, and the pins of the power module are inserted into the anti-misalignment plate 3 that matches the pins. At this time, the power module can be fixed on the fixture. Start the marking machine to complete the marking. If the power module is placed in reverse, the pins will not match.
[0039] Although embodiments of the present invention have been shown and described in detail above, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
