Description

Technical Field

[0001] The utility model belongs to the technical field of PCB board processing, and in particular relates to a jig for pressing a plate and applying adhesive tape. Background Art

[0002] Applying insulation tape to PCBs effectively isolates different circuits or layers on a PCB, preventing electrical shorts. This is particularly important in multi-layer PCB designs, as it prevents direct contact between signal or power lines on different layers, potentially creating unintended electrical connections. This effectively enhances PCB performance and stability, ensuring reliable operation of electronic devices in a variety of environmental conditions.

[0003] The existing Chinese patent with the announcement number CN215187618U discloses a tape-assisted mounting jig, comprising a base and a positioning upper frame located on the upper portion of the base; the base is a structure that is narrow in the middle and wide at the front and rear ends, and a positioning groove is provided in the middle of the upper surface of the base for positioning the aluminum plate to be glued, with two grooves formed between the narrow portion in the middle of the base and the wide portions at both ends of the base; when in use, the bottoms of the two grooves are located on the inner side of the edge of the aluminum plate to be glued; the rear side of the base is hinged to the rear side of the positioning upper frame, and the positioning upper frame is a frame-shaped structure with an open front side. The utility model achieves precise positioning of the aluminum plate and the adhesive tape to be mounted by designing the positioning groove in the middle of the base and the three-sided limit of the positioning upper frame. The entire jig is simple and reliable to operate, efficient and stable, reduces interference from human factors, improves product efficiency, and improves quality stability.

[0004] Regarding the related technologies mentioned above, the rotating positioning upper frame sticks the adhesive tape on the material board. However, in actual operation, since one side of the positioning upper frame is hingedly installed on the top side of the base, when sticking the adhesive tape, it is necessary to manually apply pressure to the upper end of the positioning upper frame to stick the adhesive tape near the hinged end on the material board, which is a more cumbersome operation.

[0005] Therefore, we proposed a press plate adhesive tape jig to solve the above problems. Utility Model Content

[0006] The purpose of the present invention is to provide a jig for applying adhesive tape to a pressing plate, so as to solve the problem in the background art that the adhesive tape is difficult to be completely attached to the material plate.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figures 1-4 The pressure plate adhesive tape jig includes a adhesive structure 1, which includes a base plate 11 and an inverted U-shaped support frame 12 installed on one side of the top of the base plate 11. A pressure rod 13 is installed on one side of the inverted U-shaped support frame 12 and above the base plate 11. A downward pressing component 14 is provided above the base plate 11 and on one side of the inverted U-shaped support frame 12.

[0025] Limiting rods 121 are installed on both sides of the inner bottom end of the inverted U-shaped support frame 12.

[0026] The pressing member 14 includes a pressing plate 141 and a limiting hole 142 opened in the middle end of the pressing plate 141. The bottom end of the pressing rod 13 is installed on the top end of the pressing plate 141. The limiting hole 142 is adapted to the limiting rod 121. When the pressing rod 13 is pressed down, the limiting hole 142 sets limits the downward movement of the pressing plate 141.

[0027] An air pump 122 is installed at the rear end of the inverted U-shaped support frame 12, an air hole 144 is opened at the side end of the lower pressure plate 141, a built-in groove 143 is opened inside the lower pressure plate 141, and an air pipe 123 is installed between the lower pressure plate 141 and the air pump 122. One end of the air pipe 123 is on the outside of the air hole 144, and the other end of the air pipe 123 is installed at the air extraction end of the air pump 122. The air pump 122 is used to extract air from the inside of the limiting hole 142, and the suction force is used to determine the position of the insulating sticker.

[0028] A bottom groove 145 is provided through the bottom end of the lower pressure plate 141, and a convex pressing piece 146 is installed on the outside of the bottom groove 145 and at the bottom end of the lower pressure plate 141. An I-shaped tube 147 is slidably installed at the middle end of the convex pressing piece 146, and a suction hole 148 is provided through the middle end of the I-shaped tube 147. The insulating sticker is placed on the bottom end of the I-shaped tube 147 to determine the pasting position.

[0029] The convex pressing member 146 includes a mounting frame 1461 and a rubber pad 1462 mounted on the bottom end of the mounting frame 1461. The rubber pad 1462 is provided to protect the top end of the PCB board.

[0030] A movable hole 1463 is vertically penetrated through the middle end of the mounting frame 1461 and the rubber pad 1462 , and the I-shaped tube 147 is slidably installed inside the movable hole 1463 . The diameters of both ends of the I-shaped tube 147 are larger than the diameter of the movable hole 1463 .

[0031] Support bars 111 are installed on both sides of the top of the bottom plate 11 . Clamp bars 112 are provided at the top of the support bars 111 . There are two groups of clamp bars 112 . The two groups of clamp bars 112 are used to clamp and fix the PCB board.

[0032] The bottom of the I-shaped tube 147 is pressed down by the operator, and the ... After the bottom end of 147 contacts the top of the PCB board, as the lower pressure plate 141 moves downward, the I-shaped tube 147 moves upward inside the built-in groove 143. When the top of the I-shaped tube 147 contacts the top of the built-in groove 143, the inside of the suction hole 148 is blocked by the lower pressure plate 141, so that the suction force of the I-shaped tube 147 on the insulation patch disappears. At this time, the I-shaped tube 147 sticks the insulation patch to the PCB board, and the rubber pad 1462 at the bottom of the mounting frame 1461 protects the parts on the PCB board to prevent the parts from being squeezed. Since the pressure rod 13 is at the middle end of the lower pressure plate 141, the insulation patch can adhere well to the top of the PCB board. When the lower pressure member 14 moves upward, the I-shaped tube 147 moves downward along the inside of the movable hole 1463 due to its own gravity. At this time, the inside of the suction hole 148 has suction again, which is convenient for the placement of the next group of insulation patches.

[0033] Working principle: The operator places the PCB board on the top of the support bar 111 and uses the clamping bar 112 to fix the position of the PCB board. The suction force generated by the air pump 122 places the insulation patch on the bottom end of the suction hole 148. The operator holds and presses down the handle of the pressure rod 13, causing the pressure rod of the pressure rod 13 to move downward, that is, pushing the lower pressure plate 141 downward toward the top surface of the PCB board. When the top of the I-shaped tube 147 contacts the top of the built-in groove 143, the I-shaped tube 147 sticks the insulation patch to the PCB board. The rubber pad 1462 set at the bottom end of the mounting frame 1461 protects the parts on the PCB board to prevent the parts from being squeezed.
