Description

Technical Field

[0001] The utility model relates to the technical field of detection, and in particular to a detection fixture and a detection device. Background Art

[0002] The colloid formed after the glue on the product is cured can seal the product or connect two parts on the product. The degree of curing of the colloid directly affects the sealing of the product or the stability of the connection between the two parts. When testing the degree of curing of the colloid, a common detection method is to first place the product that has been dispensed or filled with glue on a fixture, and then snap the cover onto the fixture to fix the product. Finally, drive the probe to hold the colloid, and judge the degree of curing of the colloid by the displacement of the probe and the corresponding pressure value. However, for batch products, since the glue filling technology cannot ensure that the height of the colloid formed after the product is filled with glue is completely consistent, the pressure value of the cover pressing the colloid of different heights in the above detection method varies, making it impossible to detect the colloid in its natural shape, which can easily lead to unstable detection results and low detection accuracy.

[0070] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0071] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0072] The following is a detailed description of various embodiments of the present invention in conjunction with the accompanying drawings.

[0073] See also Figure 1 The embodiment of the utility model provides a detection fixture 100 for fixing a product to be detected so as to detect the curing degree of the colloid on the product. Optionally, the product can be a display screen module in which a metal frame ring is glued to the display screen by glue. The product has a pressure area and a colloid area where the colloid is formed.

[0074] See also Figure 1 and Figure 2 The detection fixture 100 includes a base 110 and a holding mechanism 120. The base 110 is used to carry the product, and the holding mechanism 120 includes a top seat 121, a holding member 122 and an elastic member 123. The top seat 121 is detachably connected to the base 110. The top seat 121 has a detection hole 121a corresponding to the colloid. The upper surface of the holding member 122 is movably connected to the top seat 121. The lower surface of the holding member 122 is used to press the pressure area of ​​the product against the base 110, and form a gap 100b between the top seat 121 and the colloid, so that the detection member passes through the detection hole 121a and the gap 100b in turn to resist and detect the colloid. The two ends of the elastic member 123 resist the top seat 121 and the holding member 122 respectively. When the top seat 121 is connected to the base 110, the top seat 121 is spaced apart from the colloid, the lower surface of the pressing member 122 presses against the compressed area of ​​the product, and the upper surface of the pressing member 122 compresses the elastic member 123. In this embodiment, the elastic member 123 is a spring.

[0075] In the above-mentioned detection fixture 100, the setting of the elastic member 123 can prevent the holding member 122 from pressing the product too tightly and causing damage to the product. A gap 100b is formed between the top seat 121 and the colloid, so that the detection member can pass through the detection hole 121a and the gap 100b in turn to hold and detect the colloid. The holding member 122 does not hold the colloid, so that the colloid can be tested in a natural state, thereby improving the detection stability and detection accuracy of the solidification degree of the colloid.

[0076] See also Figure 1 and Figure 2 In some embodiments, the top seat 121 includes a cover member 1211 and a connector 1212. The cover member 1211 includes a main body 1211a and two abutting bodies 1211b. The detection hole 121a is movably opened in the main body 1211a. The two abutting bodies 1211b are respectively connected to the two ends of the main body 1211a. The upper surface of the pressing member 122 is movably connected to the main body 1211a, and the pressing member 122 is arranged between the two abutting bodies 1211b. In the movement direction of the pressing member 122, the distance between the abutting body 1211b and the pressing member 122 is smaller than the distance between the main body 1211a and the pressing member 122. The connector 1212 movably connects the main body 1211a and the pressing member 122, so that after the top seat 121 is connected to the base 110, the abutting body 1211b abuts against the base 110.

[0077] In this embodiment, there are a plurality of detection holes 121 a , and the plurality of detection holes 121 a are arranged at intervals along the circumference of the cover member 1211 so as to correspond to the annular colloid.

[0078] Therefore, the holding member 122 can move relative to the covering member 1211 through the connecting member 1212, and the structure is simple and the manufacturing cost is low.

[0079] See also Figure 2 and Figure 3 In some embodiments, the connector 1212 includes a connector sleeve 1212a and a connector plug 1212b. The connector sleeve 1212a is inserted into the main body 1211a and the elastic member 123 in sequence, and the connector plug 1212b is inserted from the lower surface of the holding member 122 toward the elastic member 123 and plugged into the connector sleeve 1212a.

[0080] In this embodiment, the connecting sleeve 1212a is threadedly connected to the connecting plug 1212b, and the connecting member 1212 and the elastic member 123 form a sleeve structure, so that the connecting member 1212 can limit the elastic member 123 in the radial direction of the elastic member 123, which is beneficial to improving the stability of the elastic member 123 elastically pushing the holding member 122.

[0081] See also Figure 2In some embodiments, there are multiple connecting members 1212 and multiple elastic members 123, and multiple connecting members 1212 are arranged on the main body 1211a at intervals and correspond one by one to multiple elastic members 123. In this embodiment, multiple connecting members 1212 are arranged at equal intervals.

[0082] Therefore, the plurality of elastic members 123 can push the holding member 122 at multiple points, which is beneficial to improving the uniformity of the force applied to the holding member 122 , thereby improving the stability of the elastic force applied to the holding member 122 .

[0083] See also Figure 1 and Figure 2 In some embodiments, each abutting body 1211b is provided with a first connecting groove 1211c, and the first connecting groove 1211c passes through the opposite sides of the abutting body 1211b in the movement direction of the pressing member 122. The base 110 includes a supporting member 111 and two locking members 112. The supporting member 111 is used to support the product. Both ends of the supporting member 111 have an outer protrusion 111a, and the outer protrusion 111a has a second connecting groove 111b. Each locking member 112 is connected through a first connecting groove 1211c and inserted into the corresponding second connecting groove 111b to press the abutting body 1211b to the outer protrusion 111a.

[0084] Therefore, the locking member 112 and the first connecting groove 1211 c can enable the top seat 121 and the base 110 to form a locking and matching structure, which has a simple structure and low manufacturing cost.

[0085] In some embodiments, the first connecting groove 1211c also penetrates the side of the abutting body 1211b away from the main body 1211a, so that the first connecting groove 1211c forms an open structure, which is conducive to the rapid assembly of the cover member 1211 on the outer protrusion 111a.

[0086] See also Figure 2 In some embodiments, the locking member 112 includes a rotating body 1121 and a stopper 1122. One end of the rotating body 1121 is rotatably connected to the outer protrusion 111a, and the stopper 1122 is connected to the other end of the rotating body 1121, and rotates when the rotating body 1121 rotates into the first connecting groove 1211c and the second connecting groove 111b to press the abutting body 1211b onto the outer protrusion 111a.

[0087] When assembling the top seat 121, the locking member 112 can be driven to a horizontal state by the rotating body 1121, thereby increasing the activity space above the supporting member 111, facilitating the top seat 121 to be quickly placed on the supporting member 111, thereby improving the assembly efficiency of the top seat 121 and the base 110.

[0088] See also Figure 2In some embodiments, a limiting hole 1211d is opened on the surface of the abutment body 1211b in the movement direction of the pressing member 122, and the base 110 also includes a guide pin 113, which is connected to the supporting member 111 and is used to be inserted into the limiting hole 1211d to guide the abutment body 1211b to the outer protrusion 111a.

[0089] Therefore, by inserting and cooperating the guide pin 113 with the limiting hole 1211 d , the accuracy and efficiency of assembling the top seat 121 to the base 110 can be improved.

[0090] In this embodiment, there are two limiting holes 1211d and two guide pins 113, and the two guide pins 113 correspond one to one with the two limiting holes 1211d.

[0091] See also Figure 1 and Figure 2 In some embodiments, the inspection fixture 100 further includes a plurality of positioning members 140 and a pushing assembly 150. The plurality of positioning members 140 are arranged along the circumference of the carrier 111, and the pushing assembly 150 is connected to the carrier 111 to push the product against the plurality of positioning members 140, which is conducive to improving the accuracy of fixing the product.

[0092] In this embodiment, the carrier 111 is substantially in the shape of a cuboid, the plurality of positioning members 140 are distributed on one long side and an adjacent short side of the carrier 111 , and the pushing assembly 150 is disposed at the angle between the other long side and the other short side.

[0093] See also Figure 1 and Figure 2 In some embodiments, the pushing assembly 150 includes a base 151, a linkage member 152, a pushing member 153, a reset member 154, and a movable handle 155. The base 151 is connected to a corner of the carrier 111, the linkage member 152 is movably disposed on the base 151, the pushing member 153 is connected to one end of the linkage member 152, and is used to hold the product against the multiple positioning members 140, the two ends of the reset member 154 respectively hold the pushing member 153 and the base 151, and the movable handle 155 is rotatably connected to the linkage member 152, and when rotating, it movably holds the base 151, so as to drive the pushing member 153 to hold the product against the multiple positioning members 140 through the linkage member 152. In this embodiment, the reset member 154 is a spring.

[0094] In the above-mentioned pushing assembly 150, the movable handle 155 and the base 151 form an eccentric structure. When the movable handle 155 is rotated clockwise, the movable handle 155 movably abuts against the base 151, and drives the pushing member 153 away from the positioning member 140 through the linkage member 152. At this time, the reset member 154 is compressed to the base 151 by the pushing member 153. When the movable handle 155 is rotated counterclockwise, the movable handle 155 movably abuts against the base 151, and the elastic force of the compressed reset member 154 is released, so that the pushing member 153 is elastically pushed to move closer to the positioning member 140. Among them, the movable handle 155 can also be set so that when it is rotated counterclockwise, the pushing member 153 is away from the positioning member 140, and when it is rotated clockwise, the pushing member 153 is close to the positioning member 140.

[0095] See also Figure 4 The present invention also provides a detection device 1000, comprising a detection member 200 and the detection fixture 100 of the above embodiment. The detection member 200 sequentially passes through the detection hole 121a and the gap 100b to resist and detect the colloid.

[0096] The working process of the above detection device 1000 for detecting colloid on a product is roughly as follows:

[0097] First, the stopper 1122 drives the rotating body 1121 to rotate to a horizontal position relative to the supporting member 111, and the movable handle 155 is rotated clockwise, so that a supporting area 100a for placing products is formed between the pushing member 153 and the plurality of positioning members 140 (see Figure 2 );

[0098] Next, place the product on the carrying area 100 a and rotate the movable handle 155 counterclockwise so that the push member 153 presses the product against the plurality of positioning members 140 ;

[0099] Then, the top seat 121 is driven to be placed on the bearing member 111, and the guide pin 113 is inserted into the limiting hole 1211d, and the rotating body 1121 is driven to rotate to a vertical position relative to the bearing member 111 through the stopper 1122, and the rotating body 1121 is received in the first connecting groove 1211c and the second connecting groove 111b, and the stopper 1122 is rotated to press the abutting body 1211b to the outer protrusion 111a. In this process, the pressing member 122 is subjected to the reaction force of the product to compress the elastic member 123, and one end of the detection member 200 passes through the detection hole 121a and the gap 100b to abut the colloid;

[0100] Finally, force is applied to the other end of the detection member 200 manually or through an external power mechanism to move the detection member 200 downward by a predetermined distance, and the pressure applied at this time is recorded, and the curing degree of the colloid is determined based on the pressure value.

[0101] It should be noted that the determination of the solidification degree of the colloid based on the pressure value can be directly obtained from the published documents and will not be repeated here.

[0102] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
