At present, there is no limiting carrier for assisting the laminating process of the single DAM and the single PCB, which requires high eyesight and technical level of the operators. The operators need to perform multiple positioning to determine the position of the single DAM on the single PCB, which is time-consuming and laborious. Therefore, it is necessary to provide a limiting carrier for the manual DAM laminating process, which can solve the problem in the prior art that there is no limiting carrier to assist the single DAM to be laminarized on the single PCB. Summary of the invention

[0006] When there are multiple PCB slots, the sizes and depths of the multiple PCB slots are different, so that the multiple PCB slots are arranged in a stepped and overlapping manner.

[0007] In each of the PCB slots, the height of the positioning pin is greater than the thickness of the single PCB to be embedded, so that the positioning pin can be inserted into the second positioning pin hole on the single DAM.

[0008] The diameter of the positioning pin is mm, and the apertures of the first positioning pin hole and the second positioning pin hole are both larger than the diameter of the positioning pin.

[0009] The number of the positioning pins, the second positioning pin holes and the first positioning pin holes is consistent, and at least two positioning pins, two second positioning pin holes and two first positioning pin holes are provided.

[0010] The two sides of the limiting carrier are formed with gaps, and the gaps are connected to one or more PCB slots.

[0012] 1. The utility model is provided with a limiting carrier, and the positioning pin sequentially penetrates the first positioning pin hole on the single PCB and the second positioning pin hole on the single DAM, so that the fitting position of the single DAM on the single PCB can be quickly and accurately determined, which saves time and effort, reduces the difficulty of operation, avoids dependence on the eyesight and technical level of the operator, and thus improves the fitting quality and efficiency of the single DAM.

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Please see attached Figure 1 To Attachment Figure 4A limiting carrier for a manual DAM bonding process includes a limiting carrier 1, wherein one or more PCB slots 11 are formed in the limiting carrier 1, so that a single PCB 2 can be matched and embedded in the PCB slot 11; a plurality of positioning pins 12 are arranged at intervals in the PCB slot 11, and a plurality of first positioning pin holes 21 are formed at intervals on the single PCB 2, so that when the single PCB 2 is embedded in the PCB slot 11, the plurality of positioning pins 12 respectively pass through the plurality of first positioning pin holes 21; a plurality of second positioning pin holes 31 are formed at intervals on the single DAM 3, and the plurality of positioning pins 12 can be correspondingly inserted into the plurality of second positioning pin holes 31, so that the single DAM 3 is bonded to the bonding position of the single PCB 2.

[0021] The shape and size of the PCB slot 11 can be determined according to the shape and size of a single PCB 2. If there are single PCBs 2 of various sizes, multiple PCB slots 11 can be arranged. The number of PCB slots 11 can be adaptively adjusted according to actual usage requirements, so that the limiting carrier has better versatility.

[0022] According to the alignment of the second positioning pin hole 31 and the first positioning pin hole 21, the accuracy and efficiency of the bonding position of a single DAM 3 and a single PCB 2 are guaranteed, and repeated positioning confirmation is unnecessary, thereby improving the operating efficiency of the bonding process of a single DAM 3, avoiding dependence on the eyesight and technical level of the operators, and being conducive to ensuring the bonding quality of a single DAM 3.

[0023] After the single PCB 2 is embedded through the PCB slot 11, glue is dispensed on the single PCB 2 to directly attach the single DAM 3 to the single PCB 2, ensuring that the locating pin 12 passes through the first locating pin hole 21 and the second locating pin hole 31 in sequence, thereby ensuring the efficiency and accuracy of the attachment of the single DAM 3.

[0024] Please see attached Figure 1 and attached Figure 2 When there are multiple PCB slots 11, the sizes and depths of the multiple PCB slots 11 are different, so that the multiple PCB slots 11 are arranged in a stepped and overlapping manner.

[0025] Since the shapes of single PCBs 2 of different specifications of the same model are consistent but the sizes are different, PCB slots 11 of different depths can be arranged in a stepped overlapping manner, which saves more space than the horizontal independent arrangement and can reduce the size of the limiting carrier 1 while meeting the requirements of the installation of different single PCBs 2.

[0026] In each of the PCB slots 11 , the height of the positioning pin 12 is greater than the thickness of the single PCB 2 installed therein, so that the positioning pin 12 can be inserted into the second positioning pin hole 31 on the single DAM 3 .

[0027] Preferably, the height of the locating pin 12 is consistent with the stacking thickness of the single PCB 2 and the single DAM 3, ensuring that the locating pin 12 can pass through the first locating pin hole 21 and the second locating pin hole 31 in sequence, thereby ensuring the limiting effect of the single DAM 3 on the single PCB 2, and further ensuring the pasting position accuracy of the single DAM 3.

[0028] The diameter of the positioning pin 12 is 2 mm, and the diameters of the first positioning pin hole 21 and the second positioning pin hole 31 are slightly larger than the diameter of the positioning pin 12 .

[0029] The size of the locating pin 12 and the apertures of the first locating pin hole 21 and the second locating pin hole 31 can be adaptively adjusted according to actual needs, so that the locating pin 12 can smoothly pass through the first locating pin hole 21 and the second locating pin hole 31 without shaking significantly, thereby ensuring the relative limit and positioning accuracy between a single DAM 3 and a single PCB 2.

[0030] The number of the positioning pins 12 , the second positioning pin holes 31 and the first positioning pin holes 21 is the same, and at least two positioning pins 12 , the second positioning pin holes 31 and the first positioning pin holes 21 are provided.

[0031] Preferably, three second positioning pin holes 31 and three first positioning pin holes 21 arranged in a triangle can be provided, so that the fitting position of a single DAM 3 on a single PCB 2 can be quickly and accurately determined by aligning the three second positioning pin holes 31 with the three first positioning pin holes 21 .

[0032] Notches 13 are formed on both sides of the limiting carrier 1, and the notches 13 are connected to one or more PCB slots 11, which makes it easy to embed a single PCB 2 into the corresponding PCB slot 11 by tweezers, and also makes it easy to remove a single PCB 2 from the PCB slot 11 by tweezers after the bonding is completed.

[0033] Embodiment 1:

[0034] The single PCB 2 includes a 1.6mm thick NPD1601-BD PCB and a 0.8mm thick NPD-SM02 PCB. The thickness of the single DAM 3 attached to the single PCB 2 is 0.8mm.

[0035] Please see attached Figure 3 and attached Figure 4, two PCB slots 11 are provided on the limiting carrier 1, and the two PCB slots 11 are adaptively formed according to the size and thickness of the NPD1601-BD PCB and the NPD-SM02 PCB. The groove depth of each PCB slot 11 corresponding to the NPD1601-BD PCB is 0.8mm, the diameter of the positioning pin 12 is 2mm, and the height is 1.6mm. The groove depth of each PCB slot 11 corresponding to the NPD-SM02 PCB is 1.6mm, the diameter of the positioning pin 12 is 2mm, and the height is 2.4mm. The two PCB slots 11 are arranged in a stepped overlapping manner.

[0036] When a single DAM 3 is fitted on the NPD1601-BD PCB, three positioning pin holes are opened on both the single DAM 3 and the NPD1601-BD PCB according to the fitting position between the single DAM 3 and the NPD1601-BD PCB, i.e., three first positioning pin holes 21 and three second positioning pin holes 31. When the three first positioning pin holes 21 are aligned with the three second positioning pin holes 31, the single DAM 3 can be accurately fitted at the designated position on the NPD1601-BD PCB.

[0037] Insert the NPD1601-BD PCB into the corresponding PCB slot 11, and make the three locating pins 12 in the PCB slot 11 pass through the three first locating pin holes 21 on the NPD1601-BD PCB. Apply glue on the surface of the NPD1601-BD PCB, and then attach a single DAM 3 to the NPD1601-BD PCB, and make the three locating pins 12 inserted into the three second locating pin holes 31, so that the single DAM 3 is accurately attached to the NPD1601-BD PCB.

[0038] When a single DAM 3 is fitted on the panelized NPD-SM02 PCB, three positioning pin holes are opened on both the single DAM 3 and the panelized NPD-SM02 PCB according to the fitting position between the single DAM 3 and the panelized NPD-SM02 PCB, namely, three first positioning pin holes 21 and three second positioning pin holes 31, so that when the three first positioning pin holes 21 are aligned with the three second positioning pin holes 31, the single DAM 3 can be accurately fitted at the designated position on the panelized NPD-SM02 PCB.

[0039] Insert the panelized NPD-SM02 PCB into the corresponding PCB slot 11, and make the three locating pins 12 in the PCB slot 11 pass through the three first locating pin holes 21 on the panelized NPD-SM02 PCB. Apply glue on the surface of the panelized NPD-SM02 PCB, and then attach a single DAM 3 to the panelized NPD-SM02 PCB, and make the three locating pins 12 inserted into the three second locating pin holes 31, so that the single DAM 3 is accurately attached to the panelized NPD-SM02-BD PCB.
