[0002] During the manufacturing process, alloy resistor chips typically undergo an encapsulation process, which involves using a molding compound to thermo-encapsulate the alloy resistor chips. This provides physical protection for the alloy resistor chips, reduces the impact of environmental factors, and facilitates their installation and connection with other components during use.

[0003] According to the announcement CN221638974U, an alloy resistor sheet adhesive removal mold includes: an upper mold, comprising an upper mold base and an upper template, the upper template being disposed on one side of the upper mold base, and adhesive removal needles on the side of the upper template facing away from the upper mold base, the adhesive removal needles being used to remove adhesive strips from the alloy resistor sheet; a lower mold, comprising a lower mold base and a lower template, the lower template being disposed on one side of the lower mold base, the lower template having a through adhesive removal channel corresponding to the adhesive removal needles, and a through discharge hole on the lower mold base, the discharge hole being connected to the adhesive removal channel; and a positioning mechanism for limiting the position of the alloy resistor sheet. This application has the effect of reducing the production cost and time cost of removing adhesive strips from alloy resistor sheets and improving the yield of alloy resistor sheets.

[0004] The above-mentioned device can reduce the production cost and time cost of removing adhesive strips from alloy resistor sheets and improve the yield rate of alloy resistor sheets. According to the instruction manual and the attached drawings, when the adhesive removal needle is damaged, it needs to be replaced by removing the fixing plate. The fixing plate is fixed by multiple sets of bolts, and the disassembly process requires the operator to manually perform repeated disassembly, which takes a long time. Utility Model Content

[0022] Reference Figures 1 to 5 In this embodiment of the utility model, an alloy resistance sheet de-adhesion mold includes an upper template 1, a positioning plate 2 at the top of the upper template 1, and fixed pressure plates 6 symmetrically arranged at the top of the upper template 1. Multiple de-adhesion needles 4 are symmetrically arranged in the middle of the two sets of fixed pressure plates 6. A groove 10 is symmetrically opened at the top of the upper template 1, and an L-shaped locking rod 11 is fixedly installed inside the groove 10. A groove 2 14 is symmetrically opened at the bottom of the fixed pressure plate 6, and a rotating shaft 7 is fixedly installed inside the groove 2 14. An L-shaped locking rod 2 8 is arranged inside the groove 2 14 and is rotatably connected to the rotating shaft 7.

An installation rod 3 fixed to the upper template 1 is symmetrically threaded at the top of the positioning plate 2, and de-adhesion holes 5 are symmetrically opened at the top of the positioning plate 2.

[0023] The above scheme is adopted as follows: symmetrical rectangular grooves 10 are opened at the top of the upper template 1, and L-shaped locking rods 11 made of 45# steel are fixedly installed in the grooves. The bottom of the fixed pressure plate 6 is symmetrically provided with grooves 14, with 40Cr material rotating shafts 7 inside. The L-shaped locking rods 12 are rotatably connected to the rotating shafts 7 through bearings. The reset spring 9 is installed in the groove 14, and one end is welded to the L-shaped locking rod 12. Rods 3 are symmetrically distributed at the top of the positioning plate 2 and connected to the upper template 1 through threads. The surface of the positioning plate 2 is provided with glue removal holes 5. The overall structure achieves rapid positioning through spring reset and mechanical locking.

[0024] Reference Figures 1 to 5A rotating shaft 12 is rotatably connected inside the second groove 14, and a cam 13 is fixedly installed at one end of the rotating shaft 12. A third groove 15 is symmetrically opened at one end of the fixed pressure plate 6 on the opposite side of the second groove 14. A rotating handle 17 is fixedly installed through the rotating shaft 12 through the third groove 15. A limiting gear 16 is set inside the third groove 15. The limiting gear 16 is fixedly installed with the rotating shaft 12. An installation block 18 is fixedly installed inside the third groove 15 and directly above the limiting gear 16. A sliding groove 19 is opened at the bottom of the installation block 18. A wedge-shaped limiting rod 20 is slidably connected inside the sliding groove 19. The wedge-shaped limiting rod 20 is adapted to the tooth groove of the limiting gear 16. A pull rod 22 is slidably connected to the top of the installation block 18. The pull rod 22 is fixedly installed through the installation block 18 and wedge-shaped limiting rod 20. A connecting spring 21 is fixedly installed inside the sliding groove 19. One end of the connecting spring 21 is fixedly installed with the wedge-shaped limiting rod 20.

[0025] The above scheme is adopted: a 40Cr material rotating shaft 12 is rotatably connected inside the groove 2 14 through a deep groove ball bearing, and an HT200 gray cast iron cam 13 is installed at the end of the shaft. A rectangular groove 3 15 is opened at one end of the fixed pressure plate 6. The rotating shaft 12 passes through the groove and is connected to a 45# steel rotating handle 17. The surface is knurled to increase the friction coefficient. An alloy steel limit gear 16 is set in the groove 3 15 and is connected to the rotating shaft 12 by a flat key to transmit torque. A sliding groove 19 is opened at the bottom of the mounting block 18. A GCr15 bearing steel wedge-shaped limit rod 20 is slidably connected in the groove and is engaged with the tooth groove of the limit gear 16. A 304 stainless steel pull rod 22 is set in the sliding hole at the top of the mounting block 18. A connecting spring 21 is installed in the sliding groove 19. The overall structure achieves angular positioning through gear and rack, and the spring reset mechanism provides continuous locking force.

[0026] Reference Figures 1 to 5 The top of the L-shaped locking rod 11 end is a bevel, and the bottom of the L-shaped locking rod 28 end is a bevel.

[0027] The above solution is adopted: the top end of the L-shaped locking rod 11 is machined with a bevel, and the bottom end of the L-shaped locking rod 28 is correspondingly set with a bevel to realize the quick locking function. When unlocking, the cam 13 rotates at a certain angle to push the L-shaped locking rod 28 to rotate around the rotating shaft 7. At this time, the L-shaped locking rod 28 will be released from the locking state with the L-shaped locking rod 11, and then the fixed pressure plate 6 can be quickly disassembled from the upper template 1.

[0028] The working principle of this utility model is as follows: The L-shaped locking rod 28 remains vertical under the action of the return spring 9. The cam 13 does not apply pressure to it. The fixed pressure plate 6 is aligned with the installation position of the upper template 1, so that the groove 2 14 aligns with the groove 10. The fixed pressure plate 6 is pressed down, and the inclined surface of the L-shaped locking rod 11 contacts the inclined surface of the L-shaped locking rod 28, forcing the L-shaped locking rod 28 to rotate around the pivot 7. When the fixed pressure plate 6 is fully in contact with the upper template 1, the L-shaped locking rod 28 springs back to a vertical state under the action of the return spring 9, forming a hook-lock structure with the L-shaped locking rod 11, thus completing the process. Locking: During disassembly, pull the lever 22 upwards to disengage the wedge-shaped limit lever 20 from the tooth groove of the limit gear 16, releasing the lock on the rotating shaft 12. Then, the operator rotates the handle 17 to rotate the rotating shaft 12. As the rotating shaft 12 rotates, the cam 13 will press the L-shaped locking lever 2 8. At this time, the L-shaped locking lever 2 8 will be released from the locking state with the L-shaped locking lever 1 11. Then, the fixed pressure plate 6 can be quickly disassembled from the upper template 1, reducing the time-consuming repeated operations when replacing the glue removal needle 4 and increasing the replacement efficiency.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
