Abstract
Description
Technical Field
[0001] This utility model relates to the field of chip mounters, and more particularly to a chip mounter for circuit board production. Background Technology
[0002] A pick-and-place machine, also known as a placement machine, is a device that uses a moving placement head to accurately place surface mount components onto PCB pads.
[0003] During circuit board manufacturing, we encountered a problem when using a pick-and-place machine for component mounting: the solder pads were not properly secured on the worktable. This instability caused vibrations in the pick-and-place machine during operation, which in turn caused the solder pads to shift, affecting the mounting accuracy and the quality of the final product.
[0004] To address the aforementioned issues, this application proposes a chip mounter machine for circuit board production. Utility Model Content
[0005] (I) Purpose of the utility model
[0006] To address the technical problems existing in the background art, this utility model proposes a circuit board manufacturing chip mounter. This utility model incorporates a pressing mechanism to facilitate the stability of the circuit board position during soldering, thereby increasing the quality of chip mounting.
[0007] (II) Technical Solution
[0008] To solve the above problems, this utility model provides a circuit board manufacturing pick and place machine, including a pick and place machine body and an operating table connected to the pick and place machine body, wherein the operating table is provided with a fixture for placing circuit boards;
[0009] An opening is formed on one side of the fixture, and a limiting part is rotatably provided at the opening;
[0010] The other side of the fixture is connected to an inclined table via a hinge, and the operating table is equipped with a linear driver for moving the inclined table.
[0011] The operating table is equipped with a pressing mechanism for pressing down on the circuit board.
[0012] Preferably, the limiting part includes a limiting strip, which is rotatably connected to the fixture via a second hinge.
[0013] Preferably, the side of the limiting strip away from the fixture forms an inclined surface.
[0014] Preferably, the pressing mechanism includes a mounting frame, a sleeve, a moving rod, and a roller. The mounting frame is fixedly mounted on the operating table, the sleeve is fixedly fitted onto the mounting frame, one end of the moving rod slides into the interior of the sleeve and is connected to the closed end of the sleeve via a spring, and the moving rod is rotatably connected to the roller via a rotating shaft.
[0015] Preferably, the outer periphery of the roller is fixedly fitted with a rubber sleeve.
[0016] The above-mentioned technical solution of this utility model has the following beneficial technical effects:
[0017] The linear actuator drives the tilting stage to move horizontally, thereby moving the fixture out of the operating table. When the fixture moves out of the operating table, the fixture tilts under the action of hinge one and hinge two. At this time, the limit strip releases the seal on one side of the fixture, which facilitates the removal or placement of the circuit board. When the linear actuator drives the fixture back to the operating table, the tilting stage moves back continuously and presses against the roller. As the fixture moves to the operating table, the limit strip rotates to seal the fixture. As the fixture moves back continuously, it presses against the roller to increase the stability of the circuit board during placement and improve the quality after placement.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0023] like Figure 1-3As shown, the present invention proposes a circuit board manufacturing pick and place machine, which includes a pick and place machine body 1 and an operating table 2 connected to the pick and place machine body 1. The operating table 2 is provided with a fixture 3 for placing circuit boards.
[0024] An opening is formed on one side of the fixture 3, and a limiting part 4 is rotatably provided at the opening; the limiting part 4 includes a limiting strip 41, which is rotatably connected to the fixture 3 via a second hinge 42, and the side of the limiting strip 41 away from the fixture 3 forms an inclined surface.
[0025] On the other side of the fixture 3, an inclined table 6 is rotatably connected via a hinge 5. The operating table 2 is equipped with a linear actuator 7 for moving the inclined table 6. The driving end of the linear actuator 7 is fixedly connected to the end of the inclined table 6. The linear actuator 7 is a rodless cylinder or an electric guide rail.
[0026] The operating table 2 is equipped with a pressing mechanism 8 for pressing the circuit board.
[0027] Specifically, the pressing mechanism 8 includes a mounting frame 81, a sleeve 82, a moving rod 83, and a roller 84. The mounting frame 81 is fixedly mounted on the operating table 2, the sleeve 82 is fixedly fitted onto the mounting frame 81, one end of the moving rod 83 slides into the inside of the sleeve 82 and is connected to the closed end of the sleeve 82 through a spring 85, and the moving rod 83 is rotatably connected to the roller 84 through a rotating shaft.
[0028] It should be noted that, under the action of spring 85, the height of the roller 84 is adjusted to match the pressure surface.
[0029] Furthermore, the outer periphery of the roller 84 is fitted with a rubber sleeve.
[0030] It should be noted that the rubber sleeve increases the friction when pressing against the circuit board.
[0031] In this invention, the linear actuator 7 drives the tilting stage 6 to move horizontally, thereby moving the fixture 3 out of the operating table 2. When the fixture 3 moves out of the operating table 2, it tilts under the action of hinge 5 and hinge 42. At this time, the limiting strip 41 releases the seal on one side of the fixture 3, which facilitates the removal or placement of the circuit board. When the linear actuator 7 drives the fixture 3 back to the operating table 2, the tilting stage 6 moves back continuously and presses against the roller 84. As the fixture 3 moves onto the operating table 2, the limiting strip 41 rotates to seal the fixture 3. As the fixture 3 moves back continuously, it presses against the roller 84, thereby increasing the stability of the circuit board during placement and improving the quality after placement.
[0032] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
