Description

Technical Field

[0001] The present invention relates to the field of chip mounting technology, in particular to a chip mounting machine. Background Art

[0002] At present, the insulation layer patches in China generally adopt the manual patching method. Due to the effect of the internal flow field when the propellant in the engine burns, insulation layer patches of different thicknesses and different materials need to be pasted on different parts of the engine casing. For large-mouth engines with front and rear head diameters above 405mm, the front and rear heads and straight sections are generally pasted manually into the engine casing. The patch cycle of an engine casing takes 15 days, and the patch efficiency is low. For engine casings with front and rear head diameters below 405mm, it is impossible to manually paste the straight section due to size limitations. At present, the main method used in China is to manually paste the front and rear heads with molded pads, and for the straight section, airbags are used instead of manual pasting, but there are problems such as inaccurate positioning of the straight section, low patch quality, and low patch efficiency. In recent years, China has conducted research on the patch technology of some small-mouth engines and achieved some results, but there is still a lack of corresponding molding technology for the internal insulation and overall molded mechanized positioning patches of the straight section, and the traditional patch method is still maintained.

[0033] At present, the insulation layer patches in China generally adopt the manual patching method. Due to the effect of the internal flow field when the propellant in the engine burns, insulation layer patches of different thicknesses and different materials need to be pasted on different parts of the engine casing. For large-mouth engines with front and rear head diameters above 405mm, the front and rear heads and straight sections are generally pasted manually into the engine casing. The patch cycle of an engine casing takes 15 days, and the patch efficiency is low. For engine casings with front and rear head diameters below 405mm, it is impossible to manually paste the straight section due to size limitations. At present, the main method used in China is to manually paste the front and rear heads with molded pads, and for the straight section, airbags are used instead of manual pasting, but there are problems such as inaccurate positioning of the straight section, low patch quality, and low patch efficiency. In recent years, China has conducted research on the patch technology of some small-mouth engines and achieved some results, but there is still a lack of corresponding molding technology for the internal insulation and overall molded mechanized positioning patches of the straight section, and the traditional patch method is still maintained.

[0034] In view of this, the present invention provides a chip mounter, aiming to improve the technical problems of low chip mount accuracy and low working efficiency in the prior art. Figure 1 to Figure 2 This is an embodiment of the chip placement machine provided by the present invention.

[0035] See also Figure 1 The present embodiment provides a chip mounter 100 for mounting chips inside an engine housing. The chip mounter 100 has a first direction and a second direction that are arranged crosswise. The chip mounter 100 includes:

[0036] seat body;

[0037] A support shaft 101, having an axial direction coincident with the first direction and a radial direction coincident with the second direction, and the support shaft 101 is rotatably mounted on the seat body around its own axis;

[0038] A sheet rolling structure, provided on the outer peripheral side wall of the support shaft 101, for rolling up the patch so that the outermost patch abuts against the inner wall of the engine housing;

[0039] A sheet pressing mechanism, comprising a roller 102 extending along the first direction, the roller 102 being installed in parallel and at intervals on the support shaft 101, and the roller 102 being retractable relative to the peripheral side wall of the support shaft 101 along the second direction, so that when the roller 102 rotates along the axis of the first direction and extends along the second direction, the outermost patch is attached to the inner wall of the engine housing; and,

[0040] A driving device is drivingly connected to the support shaft 101, and the driving device is used to drive the support shaft 101 to rotate.

[0041] In the technical solution provided in this embodiment, it is necessary to paste an insulating film, usually referred to as a patch, on the inside of the engine casing. Before this, patches were usually pasted manually by professional technicians, but even the most professional technicians would inevitably have different pressing forces in different places during the process of pasting a large area of ​​insulating film, which would lead to different degrees of firmness of the paste, and different pressing forces would cause different deformations of the insulating film, which would lead to uneven thickness of the insulating film, and if the engine casing is cylindrical, there would be a problem of uncertain margin at the joint after pasting a circle. In this embodiment, the above problems are solved by using a highly automated patch machine 100. The support shaft 101 can rotate around its own axis, and a film winding structure for rolling up the patch and a roller 102 for pressing the patch onto the inner wall of the engine casing are distributed at intervals on the side walls of the support shaft 101. A roll of thermal insulation film is rolled on the roll structure. When the support shaft 101 extends into the engine housing, it rotates 90 degrees counterclockwise. Under the action of gravity, the thermal insulation film on the roll structure, which is at the outermost layer, will abut against the inner wall of the engine housing. At this time, the support shaft 101 begins to rotate slowly and uniformly counterclockwise. The roller 102, driven by the support shaft, rolls around the inner wall of the engine housing for one circle to stick the thermal insulation film on the inner wall of the engine housing. The patch efficiency is high and the patch quality is highly controllable, so that the patch is accurately and firmly attached to the inner wall of the housing.

[0042] Furthermore, in this embodiment, the sheet pressing mechanism further comprises a mounting seat 103 and a first driving cylinder. The mounting seat 103 is telescopically arranged on the peripheral side wall of the support shaft 101 along the second direction. The mounting seat 103 is provided with a mounting groove extending along the first direction. The roller 102 is rotatably arranged in the mounting groove around the axis of the first direction, and at least partially protrudes from the notch of the mounting groove. The first driving cylinder has a first power output shaft that is telescopically arranged along the second direction, and the first power output shaft is drivingly connected to the mounting seat 103. The first driving cylinder drives the roller 102 to be telescopic along the second direction. When it is not in the patch working state, the first driving cylinder drives the roller 102 to contract so that the support shaft can easily enter and exit the interior of the engine housing. When patching is required, the first driving cylinder can be controlled to drive the roller 102 to abut against the inner wall of the engine housing to stick the thermal insulation film.

[0043] Furthermore, in this embodiment, the sheet pressing mechanism further includes a plurality of rollers, each of which is rotatably mounted on the side wall of the mounting groove around the first direction axis and slidably cooperates with the peripheral side wall of the roller 102 to reduce the friction between the roller 102 and the side wall of the mounting seat 103 during the rotation process.

[0044] Furthermore, in this embodiment, the support shaft 101 is provided with a connecting hole extending through along the second direction, and the pressing mechanism further includes a connecting rod, one end of which is connected to the mounting seat 103 and the other end of which is inserted into the connecting hole.

[0045] Furthermore, in this embodiment, the film winding structure includes two supports 106 and a film winding shaft 104, and the two supports 106 are arranged at intervals along the first direction on the peripheral side wall of the support shaft 101; the opposite ends of the film winding shaft 104 are movably mounted on the two supports 106, and the film winding shaft 104 has an active stroke approaching and moving away from the support shaft 101, so that the film winding shaft forms different angles with the support shaft.

[0046] Further, see Figure 2 In this embodiment, each of the supports 106 is provided with a slide groove 107, which extends obliquely from one side of the support 106 to the other side. At the beginning, the film reel 104 is installed at the end of the slide groove 107 close to the support shaft 101, which can facilitate the support shaft 101 to enter and exit the engine housing; after rotation, under the action of gravity, it rolls along the slide groove 107 to the end away from the support shaft 101, so that the patch on the film reel 104 is better placed on the inner wall of the engine housing for the roller 102 to stick on.

[0047] Furthermore, in this embodiment, the film winding structure further includes two limiting plates 105, which are spaced apart at both ends of the film winding shaft 104 to jointly define a winding area for winding the patch, so that the patch can be wound on the film winding shaft 104 more neatly.

[0048] Furthermore, in this embodiment, the film winding structure further includes a support plate, which is arranged on the peripheral side wall of the support shaft 101 and is located below the film winding shaft 104. Since the product is long and has a large aspect ratio, in order to ensure that the disturbance of the film winding shaft 104 during the film placement process is not affected by the weight of the thermal insulation film, the support plate is used intermittently to ensure this.

[0049] Furthermore, in this embodiment, the film take-up shaft 104 and the roller are arranged on the support shaft 101 at an interval of 90°.

[0050] It should be noted that the film reel 104 includes an inner lining and an outer covering, the inner lining is made of a metal material, and the outer covering is made of a polytetrafluoroethylene material.

[0051] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
