It should be understood that the specific implementation methods described in this specification are only for explaining the utility model, and are not intended to limit the utility model.

[0027] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0028] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0029] In an embodiment of the utility model, an SMT tape splicing jig 100 is provided, which is used to splice two tapes to be spliced ​​together through a splicing tape, so that the next roll of tape can be connected without stopping the operation of the equipment, thereby improving production efficiency.

[0030] like Figure 1-Figure 4 As shown, the SMT tape splicing fixture 100 includes a base 10 and a cover plate 20 .

[0031] The base 10 and the cover plate 20 are both sheet-like plates, and are hinged at one end close to each other through a rotating shaft (not shown in the figure). That is, the rear end of the cover plate 20 is rotatably connected to the rear end of the base 10, and the cover plate 20 and the base 10 can be freely turned over. When in use, the material strip is fixed on the base 10, and the cover plate 20 presses the base 10 to achieve cutting of the material strip and pressurization of the material strip when connecting the material strip.

[0032] In an embodiment of the utility model, the base 10 is provided with a splicing tape pad (not shown in the figure). The splicing tape pad is in the shape of a strip, used to carry the tape to be spliced, and convenient for taking the tape. Specifically, the base 10 is provided with a card slot 11, and the splicing tape pad is embedded in the card slot 11. That is, the splicing tape pad is a detachable structure, and different splicing tape pads can be selected according to different tape specifications. In this embodiment, the splicing tape pad is a rubber strip, so it has a certain elasticity. When the pressing block 21 is connected, it can provide a certain stress buffer to avoid damage to the electronic devices in the tape. Among them, when using a jig to connect two tapes, it is necessary to use a splicing tape for bonding. The splicing tape pad can also be padded by the splicing tape pad, which is convenient for fingers to take the folded splicing tape.

[0033] The cover plate 20 is provided with a pressing block 21 at a position corresponding to the pad of the material connection tape. The surface of the pressing block 21 facing away from the cover plate 20 is flush, so that the two material strips to be connected can be pressed and bonded through the material connection tape by a pressing action, without generating many pressing dead angles. A plurality of avoidance circular holes 201 are provided on the flush surface of the pressing block 21. The position of the avoidance circular holes 201 can correspond to the position of the electronic components of the material strip to be connected. At the same time, by designing a plurality of avoidance circular holes 201, multiple types of material strips can be adapted. Furthermore, the plurality of avoidance circular holes 201 are all located on the same straight line and are evenly spaced to match the circular holes at the edge of the SMT material strip.

[0034] Furthermore, a connecting hole 202 is provided between two adjacent avoidance circular holes 201 at the preset position of the pressing block 21. The connecting hole 202 is connected to the two adjacent avoidance circular holes 201, and its radius is greater than the radius of the avoidance circular hole 201. In this embodiment, a connecting hole 202 is provided between the second avoidance circular hole 201 and the third avoidance circular hole 201 from left to right, and between the second avoidance circular hole 201 and the third avoidance circular hole 201 from right to left, and the connecting hole 202 is used to further avoid electronic devices with larger material strip connection positions during pressing.

[0035] Therefore, the splicing tape pad is used to support the two splicing tapes to be spliced, and the pressing block 21 is used to press down through the cover plate 20 to press the splicing tape tightly against the two splicing tapes to be spliced, and the avoidance circular hole 201 corresponds to the position of the electronic components in the splicing tapes to be spliced, thereby avoiding crushing the electronic components in the tapes.

[0036] Furthermore, the base 10 is also provided with a plurality of positioning holes 12. The positioning holes 12 are used to detachably fix the positioning posts (not shown in the figure). The plurality of positioning holes 12 are located on the same straight line and are parallel to the straight line where the plurality of avoidance circular holes 201 are located. Therefore, the positioning posts can be vertically fixed in the corresponding positioning holes 12 according to the hole structure of the material strip of different models, so as to perform targeted positioning of the material strip.

[0037] In some embodiments, the cover plate 20 is further provided with a cutting assembly 22. The cutting assembly 22 is used to cut the material strip. The base 10 is further provided with a cutting portion 13, and the cutting portion 13 is used to place the material strip to be cut.

[0038] Specifically, the shearing assembly 22 includes a knife seat 221 and a blade (not shown). The cover plate 20 is provided with a knife seat hole 203, and the knife seat 221 is fixedly installed through the knife seat hole 203. The side of the knife seat 221 is provided with a connecting hole 222, and the blade is installed on the knife seat 221 through the connecting hole 222, so that the blade can be easily replaced.

[0039] In some embodiments, the cover plate 20 has a first half groove 204 at one end away from the rotating shaft, and the base 10 has a second half groove 14 at one end away from the rotating shaft. When the cover plate 20 and the base 10 are attached to each other, the first half groove 204 and the second half groove 14 are together formed to form a pull groove. Therefore, after the cover plate 20 covers the base 10, the cover plate 20 and the base 10 can be opened by inserting a fingertip into the pull groove.

[0040] The working principle of the utility model is as follows:

[0041] (1) First, fix the material strip in the cutting portion 13, press the cover plate 20, cut the material strip by the cutting assembly 22, and then take out the material strip;

[0042] (2) Fix the splicing tape at the joint part and then fix the material tape, fold the splicing tape and press the cover plate 20, and press the splicing tape and the two material tapes together by pressing the cover plate 20 down to complete the splicing of the material tapes.

[0043] In summary, the SMT material strip splicing jig 100 provided by the utility model has a plurality of avoidance circular holes 201 opened on the flat surface of the pressing block 21. When the pressing block 21 presses the material strip, the avoidance circular holes 201 correspond to the positions of the electronic components in the material strip to be spliced, so that the pressing part can avoid the position of the electronic device, avoiding damaging the electronic devices in the material strip, thereby improving the splicing processing yield.

[0044] The present invention is not limited to what is described in the specification and implementation modes, and therefore, additional advantages and modifications can be easily realized by those familiar with the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrative examples shown and described herein.
