Description

Technical Field

[0001] This utility model relates to the field of chip processing, and specifically to a film cutting tool. Background Technology

[0002] In the ongoing development of the semiconductor industry, chip sizes are evolving towards ever smaller dimensions. The smaller the chip size, the more stringent the requirements for the vacuum environment of the equipment become. When chip sizes reach a certain level, traditional fixture-based loading and cutting methods are no longer applicable, necessitating the use of a laminating machine for film application. The specific process is as follows: First, the product is placed on the laminating machine platform and secured using vacuum adsorption; then, a ring is placed on the platform; next, the UV film is adhered to the ring, thus securing the product; then, a cutting blade is used to remove the UV film; after that, the UV film is removed, and any excess film on the ring's positioning holes is removed a second time; finally, the ring is placed on the machine table to begin production.

[0003] In the above operation, the existing film applicator's cutting blade is only equipped with one blade, which is limited to cutting the film on the edge of the ring and cannot remove the film on the ring's positioning holes. This necessitates manual secondary cutting of the UV film on the ring's positioning holes, which not only significantly increases the time required for manual operation but also greatly reduces work efficiency. Utility Model Content

[0004] This invention provides a film cutting tool to solve the problems of the prior art.

[0005] The objective of this utility model can be achieved through the following technical solution: A film cutting tool includes: a shell, a button, a guide rod, a base plate, a fixing sleeve, a spring, a first cutter, and a second cutter. The bottom of the shell is through-hole. The guide rod is slidably disposed in the middle of the shell. The button is fixed to the upper end of the guide rod. The fixing sleeve is sleeved on the guide rod and fixed inside the shell. The base plate is fixed to the lower end of the guide rod and located below the fixing sleeve. The base plate is slidably disposed inside the shell. The spring is sleeved on the guide rod and located inside the fixing sleeve. A pressure plate is provided on the guide rod, and the pressure plate is located above the spring. The first cutter and the second cutter are both disposed on both sides of the base plate.

[0006] In a further improvement, the side end of the outer shell is provided with an opening, the protrusions on both sides of the bottom plate pass through to the outside of the opening, the two sides of the protrusion are provided with guide holes at intervals, the inner sides of the first cutter and the second cutter are provided with insert rods, the insert rods are inserted into the guide holes, and the protrusions are threaded with locking bolts for locking the insert rods.

[0007] In a further improvement, guide strips are provided on both sides of the outer shell, guide grooves are provided in the guide strips, a transparent cover plate is slidably disposed in the guide grooves, and a cutter moving cavity is provided inside the transparent cover plate.

[0008] In a further improvement, the fixing sleeve is threaded into the interior of the housing.

[0009] In a further improvement, the button, base plate, and pressure plate are all threaded onto the guide rod.

[0010] As a further improvement, the front and rear sides of the outer casing are provided with arc-shaped gripping protrusions.

[0011] Compared with the prior art, the beneficial effects of this new film-cutting tool are as follows:

[0012] The outer casing provides space for component movement. When the button is pressed, the guide rod drives the connected base plate downwards. Cutters 1 and 2, located on both sides of the base plate, move down simultaneously to cut the UV film. At this time, the pressure plate on the guide rod compresses the spring within the fixed sleeve of the guide rod, storing elastic potential energy. When the button is released, the spring releases its elastic potential energy to push the pressure plate, causing the guide rod, button, and cutters to return to their original positions. The equipped cutters 1 and 2 can simultaneously cut the film on the edge of the ring and the positioning hole, avoiding the need for manual secondary cutting of the film on the positioning hole, improving work efficiency, and reducing operator time.

[0019] The following is a description of the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.

[0020] Example 1

[0021] A film cutting tool includes: a housing 1, a button 2, a guide rod 3, a base plate 4, a fixing sleeve 5, a spring 6, a first cutter 7, and a second cutter 8. The bottom of the housing 1 is through-hole. The guide rod 3 is slidably disposed in the middle of the housing 1. The button 2 is fixed to the upper end of the guide rod 3. The fixing sleeve 5 is sleeved on the guide rod 3 and fixed inside the housing 1. The base plate 4 is fixed to the lower end of the guide rod 3 and located below the fixing sleeve 5. The base plate 4 is slidably disposed inside the housing 1. The spring 6 is sleeved on the guide rod 3 and located inside the fixing sleeve 5. The guide rod 3 is provided with a pressure plate 31, which is located above the spring 6. The first cutter 7 and the second cutter 8 are both disposed on both sides of the base plate 4.

[0022] like Figures 1-4 As shown, the working principle of this utility model is as follows:

[0023] The basic components of the membrane cutter include a housing 1, a button 2, a guide rod 3, a base plate 4, a fixing sleeve 5, a spring 6, a first cutter 7, and a second cutter 8. The bottom of the housing 1 is open, providing space for the internal components of the cutter to move. The guide rod 3 can slide in the middle of the housing 1, with the button 2 fixed at its upper end and the base plate 4 fixed at its lower end, forming a vertically movable linkage structure. The spring 6 is fitted onto the guide rod 3 and located within the fixing sleeve 5, with a pressure plate 31 on the guide rod 3 positioned above the spring 6. When the button 2 is pressed, the guide rod 3 moves downward, and the pressure plate 31 compresses the spring 6, storing elastic potential energy. When the button 2 is released, the spring 6 releases its elastic potential energy, pushing the pressure plate 31 upward, which in turn causes the guide rod 3 and the button 2 to return to their original positions. The first cutter 7 and the second cutter 8 are located on both sides of the base plate 4. When the button 2 is pressed, causing the guide rod 3 to move the base plate 4 downward, the first cutter 7 and the second cutter 8 move downward accordingly, contacting the UV film and cutting it.

[0024] Compared to traditional film cutting knives with only one blade, this knife is equipped with two cutting blades, which can simultaneously cut the film on the edge of the ring and the positioning hole, avoiding the need for manual secondary cutting of the film on the positioning hole, improving work efficiency and reducing operator time. The cutting blades are raised and lowered by pressing a button, making operation simple and convenient and reducing the labor intensity of operators.

[0025] As a further preferred embodiment, the outer casing 1 has an opening 11 on its side, and the protrusions 41 on both sides of the bottom plate 4 pass through to the outside of the opening 11.

The guide grooves 13 provide guidance for the sliding of the transparent cover plate 14, allowing it to be stably installed on the outer casing 1. The transparent cover plate 14 protects the cutter from external dust, debris, etc., preventing them from entering the cutter and affecting its normal operation. On the other hand, the operator can observe the working status of the cutter through the transparent cover plate 14, promptly identify problems during the cutting process, such as whether the cutter is deviating or whether the cutting is smooth, and make timely adjustments.

[0029] As a further preferred embodiment, the fixing sleeve 5 is threadedly connected to the inside of the outer casing 1. The threaded connection allows the fixing sleeve 5 to be securely installed inside the outer casing 1, while also facilitating disassembly.

[0030] In a further preferred embodiment, the button 2, the base plate 4, and the pressure plate 31 are all threadedly connected to the guide rod 3. During the assembly of the cutter, the positions of the button 2, the base plate 4, and the pressure plate 31 can be precisely adjusted according to actual needs to ensure that parameters such as the compression of the spring 6 and the initial position of the cutter meet the requirements, thereby ensuring the stable performance of the cutter; it also facilitates quick installation.

[0031] As a further preferred embodiment, the front and rear sides of the outer casing 1 are provided with arc-shaped grip protrusions 15. The arc design conforms to ergonomic principles, so that when the operator holds the knife, the hand can naturally fit on the arc-shaped grip protrusions 15, allowing the operator to hold the knife more stably during operation, thereby improving the accuracy and safety of operation.
