[0002] An alloy resistor refers to a resistor using an alloy as the current medium, which has the characteristics of low resistance value, high precision, low temperature coefficient, impact current resistance, high power, etc., and is widely used in precision instruments, military products, aerospace electronics, new energy photovoltaic products, automobiles, etc.

[0003] The production process of alloy resistors generally includes steps such as wafer stamping and forming, laser trimming, epoxy encapsulation, removal of encapsulation runners, surface sandblasting, character code printing, curing, granulation, etc. Among them, in the epoxy encapsulation work, there will be phenomena of glue layer overflow or glue connection during wafer gluing, and it is necessary to remove the overflowed glue and the glued position on the wafer.

[0004] For example, the Chinese patent of the prior art CN220217858U discloses a degumming machine for chip resistors, which includes an upper degumming structure, a lower degumming structure and a height adjustment module. The height adjustment module is fixedly connected above the upper degumming structure, and the lower degumming structure is movably connected below the upper degumming structure; the upper degumming structure includes a cover plate, two small rotating plates are rotatably connected to both sides below the cover plate, a double-sided baffle is rotatably connected below the small rotating plate, large rotating plates are fixedly connected to both sides of the double-sided baffle, and a rotating shaft is fixedly connected above the large rotating plates.

[0005] However, the use of the degumming machine in the above prior art is relatively inconvenient, it cannot effectively remove the overflowed and connected glue on the alloy resistor, a large amount of time is required to remove the glue on the alloy resistor, the difficulty of removing the glue is high, and it cannot perform degumming operations at multiple positions. The degumming position on the wafer is fixed and cannot be changed, resulting in low work efficiency. Summary of the Utility Model

[0006] In view of this, the purpose of the present utility model is to provide a degumming machine for alloy resistor wafers, which can improve the degumming efficiency.

[0007] To achieve the above purpose, the present utility model adopts the following content:

[0008] A degumming machine for alloy resistor wafers provided by the present utility model includes a fixed base, a human-machine interaction unit, a transverse movement unit and a lifting unit are arranged on the surface of the fixed base, a product positioning unit is arranged at the output end of the transverse movement unit, and under the drive of the transverse movement unit, the product positioning unit can pass below the lifting unit, and a degumming unit is arranged downward at the output end of the lifting unit;

[0009] The debonding unit includes a mounting plate, a driving motor, and a rotating shaft rod. The driving motor is fixedly arranged on the mounting plate and is used to drive the rotating shaft rod to rotate. The arrangement direction of the rotating shaft rod is parallel to the width direction of the product positioning unit. A plurality of spaced saw blades are arranged in an array on the rotating shaft rod.

[0010] According to a debonder for alloy resistor chips provided by the present invention, the product positioning unit includes a base frame, a lower positioning plate, and an upper pressing plate. The base frame is arranged at the output end of the transverse movement unit. The lower positioning plate is fixedly arranged on the base frame and has a profiling positioning groove on its surface for placing the product. The lower positioning plate and the upper pressing plate are connected to each other by magnetic attraction, and the upper pressing plate and the lower positioning plate are also positioned by pins. A plurality of rows of cutting through grooves that can cooperate with the saw blades are opened on the surface of the upper pressing plate and in the profiling positioning groove. The cutting through grooves on the surface of the upper pressing plate and in the profiling positioning groove are in one-to-one correspondence up and down. For the chip placed in the profiling positioning groove, the overflow glue and connected glue positions on it are just between the upper and lower cutting through grooves. In this way, the saw blade can accurately cut the overflow glue and connected glue positions on the chip through the cutting through grooves, improving the cutting accuracy.

[0011] Further, a drawable waste collection box is also arranged on the surface of the fixed base. A pulling handle is arranged on the upper part of the waste collection box, which is used to manually control the waste collection box to move below the base frame or pull the waste collection box away from below the base frame. The waste collection box that can move below the base frame is used to collect the cut waste in time, so as to uniformly process the waste and avoid the colloid falling randomly and sticking to the equipment.

[0012] According to a debonder for alloy resistor chips provided by the present invention, support side plates for rotatably inserting the rotating shaft rod are respectively arranged on both sides of the bottom end of the mounting plate, and protective baffle plates are respectively arranged on both sides of the rotating shaft rod at the bottom end of the mounting plate.

[0013] Further, a horizontal extension plate is arranged in the middle of the inner wall of the support side plate. At least two buffer pressure rods are vertically inserted movably on the extension plate. A buffer spring that is always in a compressed state is sleeved on the buffer pressure rod, and a hole groove for one end of the buffer pressure rod to enter and exit is opened on the surface of the mounting plate. In this way, when the lifting unit controls the debonding unit to approach the product positioning unit downward, the buffer pressure rod will first contact the surface of the product positioning unit and elastically retract under the action of the buffer spring until the saw blade reaches the cutting height, using the buffer pressure rod and the buffer spring to play a buffering effect.

[0014] According to a degumming machine for alloy resistor chips provided by the present utility model, the human-machine interaction unit includes a control host, a human-machine interaction touch screen, and control buttons.

One side of the bottom end of the base frame is connected to the nut output end of the horizontal lead screw nut assembly, and the other side of the bottom end of the base frame is slidably connected to the guiding slide rail through a slider. The horizontal lead screw nut assembly realizes the translational movement of the base frame in the horizontal direction, so that the base frame moves and stops directly below the lifting unit.

[0016] Furthermore, a pair of groove sensors located outside the horizontal lead screw nut assembly and arranged front and back are provided on the surface of the fixed base, and a contact piece for triggering the groove sensors is provided on the side of the base frame.

[0018] Furthermore, a sensor is provided on the side of the upper bracket, and an induction piece for triggering the sensor is provided on the side of the upper plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] To more clearly illustrate the present utility model, the following further describes the present utility model in conjunction with preferred embodiments. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not be used to limit the protection scope of the present utility model.

[0028] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] Please refer to Figures 1 to 5 as shown. An adhesive removing machine for alloy resistor chips according to an embodiment of the present utility model includes a fixed base 1 that plays a role in supporting and fixing. On the surface of the fixed base 1, a human-machine interaction unit 10, a transverse movement unit 20, and a lifting unit 30 are provided. The transverse movement unit 20 is arranged along the length direction of the fixed base 1. The human-machine interaction unit 10 is arranged on one side of the transverse movement unit 20, and the lifting unit 30 is arranged above the middle position of the transverse movement unit 20. A product positioning unit 40 is provided at the output end of the transverse movement unit 20 for placing and fixing the chip product. Driven by the transverse movement unit 20, the product positioning unit 40 can pass under the lifting unit 30. And a downward output end of the lifting unit 30 is provided with an adhesive removing unit 50, and the lifting unit 30 controls the up and down movement of the adhesive removing unit 50.

[0030] Among them, the adhesive removing unit 50 includes a mounting plate 510, a driving motor 520, and a rotating shaft rod 530. The mounting plate 510 is fixedly arranged at the output end of the lifting unit 30. The driving motor 520 is fixedly arranged on the mounting plate 510 for driving the rotating shaft rod 530 to rotate. The arrangement direction of the rotating shaft rod 530 is parallel to the width direction of the product positioning unit 40. A plurality of spaced saw blades 531 are arranged in an array on the rotating shaft rod 530.

[0031] During use, the chip is fixed and placed through the product positioning unit, and the overflow glue and connected glue positions on the chip are exposed. The transverse movement unit drives the product positioning unit to gradually pass under the lifting unit, and then the adhesive removing unit gradually cuts the exposed overflow glue and connected glue positions on the chip on the product positioning unit. The transverse movement unit gradually pushes the product positioning unit forward. In this way, the adhesive removing unit cuts the glue layers at multiple different positions on the chip product. After the cutting work is completed, the transverse movement unit sends out the product positioning unit. After the personnel take out the chip product and put in a new chip, the above process is repeated.

[0032] Among them, the product positioning unit 40 includes a base frame 410, a lower positioning plate 420, and an upper pressing plate 430. The base frame 410 is arranged at the output end of the transverse movement unit 20. The middle position of the base frame 410 is designed to be hollow. The lower positioning plate 420 is fixedly arranged on the base frame 410, and its surface has a profiling positioning groove (not shown) for placing the sheet product.

Multiple rows of cutting through grooves 431 that can cooperate with multiple saw blades are provided on the surface of the upper pressing plate 430 and in the profiling positioning groove.

[0033] That is to say, the cutting through grooves 431 on the surface of the upper pressing plate 430 and in the profiling positioning groove are in one-to-one correspondence up and down. For the sheet placed in the profiling positioning groove, the positions of the overflow glue and the connected glue on it are just between the upper and lower cutting through grooves. In this way, the saw blade can accurately cut the positions of the overflow glue and the connected glue on the sheet through the cutting through grooves, improving the cutting accuracy.

[0034] Furthermore, a retractable waste collection box 140 is also arranged on the surface of the fixed base 1.

The waste collection box that can move to the lower part of the base frame is used to collect the cut waste in a timely manner, so as to uniformly process the waste and avoid the colloid falling randomly and sticking to the equipment.

In this way, the rotation action of the rotating shaft rod is supported by the support side plates on both sides, avoiding the phenomena of shaking and jitter during the rotation of the rotating shaft rod, and ensuring the stable rotary cutting work of the saw blade on the rotating shaft rod; the protective baffle is used to prevent the problem of colloid splashing outwards during cutting.

[0036] Furthermore, a horizontal extension plate 541 is arranged in the middle of the inner wall of the support side plate 540. At least two buffer pressure rods 550 are vertically and movably inserted on the extension plate 541. A buffer spring 551 that is always in a compressed state is sleeved on the buffer pressure rod 550, and a hole groove (not shown) for one end of the buffer pressure rod 550 to enter and exit is provided on the surface of the mounting plate 510. In this way, when the lifting unit controls the glue removing unit to approach the product positioning unit downward, the buffer pressure rod will first contact the surface of the product positioning unit and elastically retract under the action of the buffer spring until the saw blade can reach the cutting height, using the buffer pressure rod and the buffer spring to play a buffering effect.

[0037] Among them, the human-machine interaction unit 10 mainly includes a control host 110, a human-machine interaction touch screen 120, and control buttons 130.

The horizontal lead screw nut assembly realizes the translational movement of the base frame in the horizontal direction, so that the base frame moves and stops directly below the lifting unit.

[0039] Furthermore, a pair of groove sensors 101 located outside the horizontal lead screw nut assembly 210 and arranged front and back are provided on the surface of the fixed base 1, and a contact piece 440 for triggering the groove sensors 101 is provided on the side of the base frame 410. In this way, the cooperation of the groove sensors and the contact piece is used to detect the movement position state of the base frame, whether it has moved in place.

[0040] Among them, the lifting unit 30 includes an upper bracket 310 and a lower bracket 320 arranged up and down. A vertical lead screw nut assembly 311 is vertically arranged in the upper bracket 310. The top end of the lower bracket 320 is inserted with a plurality of linkage rods 322 that can move up and down through a bushing 321.
