Description

Technical Field

[0001] The utility model relates to the technical field of chip resistor processing, and more specifically, to a chip resistor fixture transfer device. Background Art

[0002] Chip resistors are a type of metal glass glaze resistors, which are made by mixing metal powder and glass glaze powder and printing them on a substrate using screen printing. They are resistant to moisture and high temperatures, and have a small temperature coefficient. After the chip resistors are processed, they need to be loaded into a designated fixture and then sprayed with electrodes. During the process of spraying electrodes, two adjacent chip resistors must be tightly attached, so the chip resistors need to be squeezed and fixed.

[0003] The utility model patent with patent publication number CN201773657U discloses a chip resistor fixture transfer device, including an upper cover, a bolt, a leaf spring and a clamping sheet; the convex surface provided on the upper part of the leaf spring is tightly attached to the lower part of the upper cover, and the upper cover and the leaf spring are threadedly connected as a whole by bolts; a slide groove is provided on the upper part of the clamping sheet, and the slide groove on the clamping sheet is placed in a square hole provided at the lower end of the leaf spring to cooperate with it and install it, so that the clamping sheet is vertically erected. The advantage of this structure is that by aligning the lower end of the clamping sheet with the The vertical groove on the inner side of the top of the clamp is slowly slid down into the clamp and pressed down on the top of the product; then move the clamp cover, insert the semicircular groove on one side of the top of the clamp cover into the horizontal groove on the top of one side of the clamp and push it to the bottom of the horizontal groove on the side, then place the clamp cover horizontally on the clamp, and insert the other side of the clamp cover into the groove at the other end of the clamp; let go at this time, and the clamp cover can be fixed on the clamp by the elastic force of the leaf spring; thereby playing a pressing effect on the strip resistors collected in the clamp.

[0004] However, in actual use, although this structure can compress the resistor, since the size of the leaf spring is a fixed pad, when the number of resistors inside the fixture is small, the compression sheet cannot contact the resistor, which affects the compression effect on the resistor.

[0022] As attached Figure 1 , 2As shown in Figure 3, the telescopic assembly includes a protective frame 5 arranged on the top of the cover plate 2, an electric telescopic rod 6 is arranged inside the protective frame 5, the output end of the electric telescopic rod 6 is connected with a fixed cylinder 7, and a movable rod 8 is arranged at the bottom of the fixed cylinder 7. A hole is opened on the surface of the cover plate 2, and the fixed cylinder 7 is located at the bottom of the cover plate 2. The bottom of the fixed cylinder 7 is fixedly connected to the surface of the pressing plate 3. When the electric telescopic rod 6 is started, the fixed cylinder 7 is driven to move, and the movable rod 8 drives the pressing plate 3 to move, so that the pressing plate 3 is in contact with the surface of the chip resistor, and the chip resistor can be pressed and fixed.

[0023] As attached Figure 1 , 4 As shown, the fixing assembly includes a threaded rod 9 arranged on the top of the two fixing plates 4, a bearing seat 10 is provided at the connection between the two threaded rods 9 and the fixing plates 4, an adjusting button 11 is provided on the top of the two threaded rods 9, a moving block 12 is threadedly sleeved on the outer side of the two threaded rods 9, a connecting ring 13 is sleeved on the outer side of the moving block 12, a pressure rod 14 is provided on one side of the connecting ring 13, and the two pressure rods 14 are both located on the top of the cover plate 2. The adjusting button 11 is rotated to make the moving block 12 drive the connecting ring 13 to move along the threaded rod 9, and the connecting ring 13 drives the pressure rod 14 to move, so that the pressure rod 14 contacts with the surface of the cover plate 2, so that the cover plate 2 can be fixed.

[0024] As attached Figure 4 As shown, connecting plates 15 are provided on both sides of the two moving blocks 12, and stretching rods 16 are provided at the bottom of the two connecting plates 15. The bottoms of the two stretching rods 16 are fixedly connected to the surface of the fixed plate 4. When the moving block 12 moves, the stretching rods 16 are driven to expand and contract, and the moving block 12 can be limited so that the moving block 12 moves parallel to the threaded rod 9 to prevent the moving rod from rotating to one side.

[0025] As attached Figure 2 , 4 As shown, a plurality of positioning rods 17 are provided on the top of the clamp 1, and a plurality of positioning holes 18 are opened on the surface of the cover plate 2. The plurality of positioning rods 17 are all engaged with the positioning holes 18. The cover plate 2 is placed on the clamp 1 so that the positioning rods 17 are located inside the positioning holes 18, so that the cover plate 2 can be limited.

[0026] As attached Figure 3 As shown, the top of the movable rod 8 passes through the surface of the fixed cylinder 7 and extends to the inside of the fixed cylinder 7. A limit plate 19 is provided on the top of the movable rod 8. A spring 20 is provided on the top of the limit plate 19. One end of the spring 20 is fixedly connected to the inner wall of the fixed cylinder 7. When the pressure plate 3 contacts the surface of the chip resistor, pressure is generated on the movable rod 8, causing the movable rod 8 to slide inside the fixed cylinder 7, causing the spring 20 to expand and contract, thereby reducing the pressure of the pressure plate 3 on the chip resistor.

[0027] Working principle of the utility model: when in use, first place the processed chip resistor inside the fixture 1, and when the chip resistor forms a moving amount inside the fixture 1, place the cover plate 2 on the fixture 1, so that the positioning rod 17 is engaged with the positioning hole 18, and the cover plate 2 can be positioned to avoid the cover plate 2 from being offset;

[0028] Then, the adjusting knob 11 is rotated to drive the threaded rod 9 to rotate, so that the moving block 12 drives the connecting ring 13 to move, and the pressing plate 3 moves to the top of the cover plate 2. When the moving block 12 moves, the stretching rod 16 at the bottom of the connecting plate 15 is driven to expand and contract, and the moving block 12 can be limited to move horizontally downward along the threaded rod 9. The cover plate 2 is pressed by the pressing plate 3, so that the cover plate 2 can be fixed, and the stability of the cover plate 2 can be improved;

[0029] Then, the electric telescopic rod 6 inside the protection frame 5 is started to drive the cylinder to move downward, so that the fixed cylinder 7 drives the movable rod 8 to move, and the movable rod 8 drives the pressure plate 3 to move downward, and the chip resistor is squeezed by the pressure plate 3 to reduce the gap between two adjacent chip resistors. When the pressure plate 3 contacts the surface of the chip resistor, the movable rod 8 is firstly driven to drive the limit plate 19 to slide inside the fixed cylinder 7, so that the spring 20 is expanded and contracted, which can reduce the pressure of the pressure plate 3 on the chip resistor, avoid the pressure plate 3 directly exerting a large pressure on the chip resistor, and prevent the chip resistor from being damaged. Through the elasticity of the spring 20, the pressure plate 3 can be slowly moved downward, so that the gap between the two adjacent chip resistors is slowly reduced, and the chip resistor can be protected, which is beneficial to improving the safety of the chip resistor.

[0030] When the chip resistor needs to be taken out, the threaded rod 9 is driven to rotate by rotating the adjusting knob 11, so that the moving block 12 drives the connecting ring 13 to move, and the pressure rod 14 is separated from the surface of the cover plate 2. Then, the connecting ring 13 is rotated to move along the moving block 12 to move the pressure rod 14 to the other side, which can prevent the pressure rod 14 from blocking the movement of the cover plate 2. Then, the cover plate 2 is pulled to move it upward along the positioning rod 17 to separate the positioning rod 17 from the positioning hole 18. The cover plate 2 drives the pressure plate 3 to be taken out from the inside of the fixture 1, and then the chip resistor can be taken and placed. In the utility model, the electric telescopic rod 6 drives the fixing cylinder 7 to move, and the movable rod 8 and the spring 20 can reduce the pressure generated by the pressure plate 3 on the chip resistor, which is beneficial to improving the safety of the chip resistor. By adjusting the position of the pressure rod 14 on the cover plate 2, the cover plate 2 can be squeezed and fixed, which is beneficial to improving the stability of the cover plate 2.
