The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] Embodiment 1

[0031] See also Figure 1-3 The first embodiment of the utility model provides a fixture cover for LED solid crystal, wire welding and glue dispensing, the fixture cover is used to press the brackets for LED solid crystal, wire welding and glue dispensing, and the fixture cover includes:

[0032] Four fixing units 10 are arranged at four corners, and each fixing unit 10 is provided with a through hole 11 for fasteners to pass through to connect to the machine platform;

[0033] At least four connecting units 20, at least one connecting unit 20 is provided between two adjacent fixing units 10, so as to connect the two adjacent fixing units 10;

[0034] When there are at least two connecting units 20 between two adjacent fixing units 10 , the two adjacent connecting units 20 are detachably connected.

[0035] In this embodiment, while ensuring the structural strength of the jig cover, the fixing unit and the connecting unit 20 can be made of hard plastic, which can reduce the overall weight of the jig cover and is simpler and more efficient than processing metal materials into a single product.

[0036] More specifically, the jig cover is formed by arranging four fixing units 10 at the corners and then arranging at least one connecting unit 20 between two adjacent fixing units 10 to connect two adjacent fixing units 10, for example, by fixing them by snapping, clamping or screwing, thereby obtaining a single-sided structure of the jig cover. By assembling in this way, a rectangular jig cover can be obtained, which can be used for pressing the bracket, and finally serving the process flow of LED die bonding, wire welding and glue dispensing.

[0037] When there are multiple connection units 20 between two adjacent fixing units 10, two sides of the connection unit 20 that are far away from each other are respectively provided with a first connection structure 21 and a second connection structure 22, and the two adjacent connection units 20 are detachably connected through the first connection structure 21 or the second connection structure 22. Specifically, one of the first connection structure 21 and the second connection structure 22 is an extension part, and the other is a recessed part, and the two adjacent connection units 20 are connected through the extension part and the recessed part.

[0038] That is to say, two adjacent connection units 20 are connected by the cooperation of the extension part and the recessed part. For example, one side of the first connection unit 20 has an extension part, and the side of the adjacent second connection unit 20 facing the first connection unit 20 has a recessed part, so that the first connection unit 20 and the second connection unit 20 can be fixed together based on the extension part and the recessed part. Of course, magnetic parts can also be set inside the two adjacent connection units 20, and automatic connection and fixation are achieved through the adsorption of the magnetic parts, thereby achieving the fixation and extension of the connection units 20.

[0039] In order to ensure the connection stability between adjacent connection units 20 in this embodiment, the extension part is a bending structure, and the recessed part corresponds to the bending structure of the extension part. More specifically, the extension part is provided with a receiving hole 23, and a telescopic positioning pin 24 is provided in the receiving hole 23. The end face of the positioning pin 24 protrudes from the surface of the extension part, so that the extension part is embedded in the recessed part and inserted into a positioning hole 26 in the recessed part. Among them, the positioning pin 24 has at least one limiting flange, and the positioning pin 24 is fixed in the receiving hole 23 by the limiting flange, and an elastic member 25 for supporting the positioning pin 24 is provided between the limiting flange and the receiving hole 23. In addition, a circular arc structure is provided on the surface of the positioning pin 24 away from the elastic member 25. Finally, it should be emphasized that the movement direction of the positioning pin 24 is perpendicular to the direction in which the extension part is embedded in the recessed part.

[0040] Specifically, in this embodiment, the extension portion of the first connecting structure 21 is a bending structure, such as an L-shape, and correspondingly, the recessed portion is also L-shaped, but they correspond to each other, and the extension portion of the first connecting structure 21 is required to be embedded between the recessed portions to achieve the connection between adjacent connecting units 20. In order to improve the connection stability between adjacent connecting units 20, a locking structure for interconnecting each other is also provided between the bending portion and the recessed portion. The locking structure includes a receiving hole 23 formed on the extension portion. A movable positioning pin 24 is provided in the receiving hole 23. The positioning pin 24 has a tendency to extend out of the surface of the extension portion at all times under the support of the elastic member 25. When the two connecting units 20 are engaged, in the process of the extension portion being inserted into the recessed portion, the positioning pin 24 can be elastically retracted and inserted into the positioning hole 26 formed on the surface of the recessed portion. In this way, the two adjacent connecting units 20 can be connected together more stably. By connecting it with the two adjacent fixing units 10, a single side of the jig cover can be formed. The jig cover can be assembled by sequential operations.

[0041] In addition, the extension and retraction direction of the positioning pin 24 is perpendicular to the direction in which the extension portion is embedded in the recessed portion. For example, when the direction in which the extension portion is embedded in the recessed portion is the X direction, the extension and retraction direction of the positioning pin 24 is the Y direction or the Z direction. The connection between adjacent connecting units 20 is achieved by limiting multiple degrees of freedom, thereby firmly connecting adjacent connecting units 20 together. In this way, when the bracket is pressed together using the jig cover, although it is assembled as a single structure, it will not fall apart due to local pressure or overall pressure.

[0042] Furthermore, the surface of the extension portion is provided with an operation window connected to the receiving hole 23, so as to release the positioning pin 24 by extending a preset device into the operation window. When the size of the jig cover needs to be changed, a preset device, such as a screwdriver, can be inserted into the operation window to press the positioning pin 24 to slide, thereby overcoming the elastic force applied by the elastic member 25, and the adjacent connection units 20 can be disassembled and separated, thereby reducing the size of the jig cover. Of course, when the size of the jig cover needs to be increased, it is only necessary to add a connection unit 20 and splice and fix it with the adjacent connection unit 20.

[0043] Finally, in order to more stably press the bracket used for LED solid crystal, welding wire and glue dispensing, the surfaces of the fixing unit 10 and the connecting unit 20 are provided with positioning steps to form a pressing step for pressing the bracket when the fixing unit 10 and the connecting unit 20 are connected as one.

[0044] During the actual use of the jig cover, the size of the jig groove cover can be adjusted accordingly by increasing or decreasing the connecting units 20, so as to correspond to the size of the bracket. In this way, when the jig cover is placed on the machine equipment to press the bracket, the pressing step can press the edge of the bracket, thereby achieving relative fixation of the jig cover and the bracket. In this way, pressing deviations will not be caused by processing operations, etc., which is beneficial to improving the pressing stability of the jig cover.

[0045] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0046] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
