Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing equipment, in particular to a glue dispensing and fixing fixture for a spring sheet. Background Art

[0002] In some electronic products, the spring piece needs to be precisely fixed to the bracket with glue. Due to the small size and light weight of the spring piece, it is currently observed manually under a microscope with the naked eye, and the spring piece is placed on the cylinder of the bracket with tweezers, and glue is applied in the gap between the spring piece and the bracket cylinder. After gluing, some spring pieces will be displaced, and then the spring piece is adjusted to the correct position with tweezers, and then the combination of the spring piece and the bracket is sent to the oven for high-temperature curing. After the glue is cured, the combination is taken under a microscope for inspection.

[0003] Currently, the position of the spring sheet needs to be adjusted manually, which is inefficient. When the assembly of the spring sheet and the bracket is transferred to the oven after gluing, slight vibrations will cause some spring sheets to move, resulting in defective products. When the glue is cured, it will shrink, and the shrinking glue will also cause some spring sheets to move, which will also result in defective products. After the glue is cured, the position and size of the assembly are manually checked, which is inefficient. Utility Model Content

DETAILED DESCRIPTION

[0018] The embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0019] Embodiment 1

[0020] This embodiment provides a spring sheet dispensing and fixing fixture.

[0021] 1. Product components and connection relationships:

[0022] like Figures 1 to 3As shown, the fixture mainly consists of: a fixed base plate 1, a movable base plate 2, a support plate 3, a positioning pin 4, a positioning pin 5, a hand screw 6, a spring sheet 7, and a bracket 8. The fixed base plate 1, the movable base plate 2 and the support plate 3 are all long strip structures. The top of the fixed base plate 1 is provided with multiple grooves along the long side direction, and a mounting position of the bracket 8 is set on the support plate 3 along the long side direction corresponding to each groove. The bracket 8 is provided with a fixing column 81, the spring sheet 7 is provided with a dispensing hole 71 installed on the fixing column 81, and one end or both ends of the spring sheet 7 are provided with a waist-shaped hole 72.

[0023] The bottom end of the fixed bottom plate 1 is provided with a plurality of first positioning holes 9 and a first mounting hole 10, and the movable bottom plate 2 is provided with a second positioning hole 11 corresponding to the position of the first positioning hole 9 and a second mounting hole 12 corresponding to the position of the first mounting hole 10. The side of the fixed bottom plate 1 opposite to the movable bottom plate 2 is provided with an inwardly recessed platform, and the bottom edge of the support plate 3 is placed in the platform. The top of the fixed bottom plate 1 is provided with a groove and a third positioning hole, and the bracket 8 is installed on the support plate 3 and the installation position of the bracket 8 is located directly below the groove. Two positioning pins 5 are provided corresponding to one waist-shaped hole 72, and are respectively inserted into the third positioning hole through the two ends of the waist-shaped hole 72 of the spring sheet.

[0024] Specifically, the fixed base plate 1, the movable base plate 2, the support plate 3, the positioning pin 4, the positioning pin 5, and the hand screw 6 are made of stainless steel with high strength and corrosion resistance; the spring sheet 7 is made of beryllium copper; and the bracket 8 is made of high temperature resistant plastic.

[0025] The assembly process of this fixture:

[0026] Insert the two positioning pins 4 into the first positioning holes 9 reserved on the side of the fixed base plate 1;

[0027] Place the support plate 3 on the bottom of the bracket 8 so that the bracket 8 is tightly attached to the fixed bottom plate 1 upwards;

[0028] Place the bracket 8 into the groove reserved at the top of the fixed base plate 1;

[0029] Use the first positioning hole 9 on the side of the fixed bottom plate 1, the second positioning hole 11 on the side of the movable bottom plate 2 and the positioning pin 4 for positioning, and pass the hand screw 6 through the second mounting hole 12 and the first mounting hole 10 to fix the movable bottom plate 2 to the fixed bottom plate 1, so that the fixed bottom plate 1 and the movable bottom plate 2 clamp the bracket 8;

[0030] Insert the positioning pin 5 into the third positioning hole reserved on the top of the fixed base plate 1. The positioning pin 5 and the third positioning hole are interference fit, and the positioning pin 5 is used to assist positioning;

[0031] Put the glue hole 71 of the spring sheet 7 on the upper end of the top fixing column 81 of the bracket 8; apply glue at the contact point between the glue hole 71 and the fixing column 81;

[0032] The whole is sent into the oven for high temperature curing;

[0033] After the glue is cured, the jig is removed and the assembly of the spring sheet 7 and the bracket 8 is taken out.

[0034] 2. Working process and principle:

[0035] There is a gap for glue application between the glue-dispensing hole on the spring sheet 7 and the fixing column on the bracket 8. This gap will cause the spring sheet to Figure 2 Movement in the X, Y, and Z directions affects the electromagnetic performance of the product.

[0036] This embodiment utilizes the waist-shaped hole originally existing on the spring piece 7, and inserts the positioning pins 5 at both ends of the waist-shaped hole, so as to utilize the principle of two points locating a straight line to position and fix the spring piece 7 in the X and Y directions.

[0037] like Figure 3 As shown, there is a specially designed platform recessed inward on the fixed base plate 1. When the support plate 3 presses the bracket 8 tightly against the bottom of the platform, the top of the platform is exactly in the same plane as the fixing surface of the spring sheet 7 on the bracket 8, thereby controlling the positioning and fixing of the spring sheet in the Z direction.

[0038] When the jig, spring sheet 7 and bracket 8 are transferred to a high-temperature oven for glue curing, since the relative positions of the spring sheet 7 and bracket 8 are fixed by the jig, the slight vibration during the transfer will not affect the product. Similarly, the contraction force during the curing of the glue will not affect the fixed spring sheet.

[0039] When the glue is cured, when the product is taken out of the oven for inspection, it is only necessary to check whether the spring piece is loose. The jig avoids the risk of position change of the spring piece 7 and the bracket 8, thereby omitting the process of measuring and inspecting the position size after the glue is cured, thereby improving production efficiency.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
