Local conformal die removal machine and method of using same

Abstract

This invention discloses a partial bonding adhesive removal machine and its usage method, belonging to the field of adhesive removal equipment. The partial bonding adhesive removal machine includes: a frame with a horizontal worktable; a take-up and unwinding module mounted on the frame, including an unwinding component and a take-up component, located on opposite sides of the worktable; the tape roll passes from the unwinding component across the worktable surface and wraps around the take-up component; and a cutting module mounted on the frame and directly above the worktable. The take-up and unwinding module allows for free take-up and unwinding of the tape, spreading it across the worktable surface. Then, the cutting lifting component moves downwards, causing the slitting component to contact the adhesive layer and slit it. Subsequently, a de-adhesive collecting roller collects the slit adhesive layer, resulting in the desired shape of the adhesive layer on the tape surface. When applying adhesive to precision parts, this allows for better product adaptation and avoids the tedious process of applying adhesive first and then manually removing it.

Description

Technical Field

[0001] This invention relates to the field of precision machining equipment, and more particularly to a partial bonding and glue removal machine and its usage method. Background Technology

[0002] In some precision manufacturing processes, such as chip manufacturing and battery cell manufacturing, adhesive layers need to be applied to the substrate. Commonly, these adhesive layers are applied using tape, which is long and thin. However, in high-precision manufacturing processes, some chips or substrates are not entirely long and thin areas for adhesive application. In these areas, the adhesive layer needs to be partially removed to avoid affecting existing components on the substrate. Since the tape itself is only a few centimeters wide, manual adhesive application cannot guarantee the dimensional accuracy of the application position, nor can it ensure the continuity of the application, thus reducing production efficiency. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a partial bonding glue removal machine and its usage method.

[0004] The technical solution of this invention is: a partial bonding and adhesive removal machine, comprising:

[0005] A frame, on which a horizontal worktable is mounted.

[0006] A roll-up / unrolling module, mounted on a frame, includes an unwinding assembly and a winding assembly, with the winding assembly and unwinding assembly located on opposite sides of a worktable. The tape roll passes over the worktable surface from the unwinding assembly and winds onto the winding assembly.

[0007] A cutting module mounted on a frame and located directly above the worktable, the cutting module comprising:

[0008] A cutting lifting assembly, wherein the cutting lifting assembly is vertically mounted on a frame, and a cutting lifting frame capable of reciprocating vertically is mounted on the cutting lifting assembly; and

[0009] A slitting and cutting assembly is installed on the cutting lifting frame. The slitting and cutting assembly includes a bidirectional conveying module that is perpendicular to the conveying direction of the conveyor belt and located directly above the conveyor belt. Two sets of needle-type slitting knives that can simultaneously move outward or inward are respectively installed on the bidirectional conveying module.

[0010] Furthermore, the bidirectional delivery module includes:

[0011] A bidirectional conveyor motor is fixedly mounted on the cutting lifting frame and vertically downwards, with a conveyor gear mounted on the output shaft of the bidirectional conveyor motor; and

[0012] Two conveying racks are provided that mesh with the conveying gear. The two conveying racks are parallel to each other and located on both sides of the conveying gear and mesh with the conveying gear at the same time. A set of needle-type semi-cutting knives is provided on each of the two conveying racks.

[0013] Furthermore, a matching output slide rail and a conveying slider are provided between the conveying rack and the cutting lifting frame, and the conveying slide rail is parallel to the conveying rack. This ensures the stable movement of the conveying rack.

[0014] Furthermore, the conveying rack and the needle-type semi-cutting knife are connected by a conveying connecting plate.

[0015] Furthermore, the needle-type semi-severing knife includes:

[0016] The tool housing is hollow within its central axis;

[0017] An adjusting nut, wherein the adjusting nut is threadedly disposed within the central axis of the tool housing; and

[0018] A semi-broken needle is installed inside the adjusting nut and extends through the lower end of the tool housing along the central axis of the tool housing. During cutting, the semi-broken needle needs to protrude from the lower end of the tool housing; the length of the protruding portion can be adjusted according to the thickness of the adhesive layer.

[0019] Furthermore, a clamping module is also provided on the frame, the clamping module comprising:

[0020] A pressing motor is fixedly mounted on the frame and faces downwards;

[0021] A clamping bracket, wherein the clamping bracket is connected to a lead screw and lead screw seat driven by a clamping motor; and

[0022] The clamping assembly is installed on the clamping bracket. Two sets of clamping assemblies are provided, and each set of clamping assemblies is respectively configured to cooperate with the drive roller and the brake roller on the worktable. This ensures the clamping of the drive roller and the brake roller, and the clamping of the tape from top to bottom ensures smooth tape discharge.

[0023] Furthermore, the clamping assembly includes a clamping roller rotatably mounted on a clamping bracket. A sliding block is provided at the end of the clamping roller, and the sliding block is positioned within a sliding groove in the clamping bracket. An adjusting screw is mounted on the sliding block, and the adjusting screw is positioned within an adjusting stop block, which is fixedly mounted to the sliding groove. An adjusting spring is sleeved on the adjusting screw, with its two ends abutting against the sliding block and the adjusting stop block, respectively. An adjusting handle is also provided on the adjusting screw. This allows for adjustment of the clamping pressure of the clamping roller, adapting to different types of tape.

[0024] Furthermore, a vertical clamping guide rail and a clamping slider are installed between the clamping bracket and the frame to ensure smooth vertical movement between the clamping components.

[0025] Furthermore, a glue removal module is also provided on the clamping bracket, the glue removal module comprising:

[0026] An optical axis, which is fixedly mounted on a clamping bracket, is provided with a film roll; and

[0027] Two sets of adhesive removal brackets are connected by bracket wall panels. The bracket wall panels are fixedly mounted on the pressing brackets. A pressure roller assembly is mounted on the adhesive removal brackets. The pressure rollers of the pressure roller assembly are rotated and press the adhesive layer of the adhesive removal roll and the tape.

[0028] Furthermore, the pressure roller assembly includes a pressure roller cylinder, which is vertically downward. A pressure roller plate is provided at the end of the pressure roller cylinder, and a pressure roller is rotatably mounted on the pressure roller plate. That is, secondary pressing is achieved through the pressure roller cylinder.

[0029] Furthermore, the adhesive removal bracket is mounted on the bracket wall panel via a manual adjustment assembly. This assembly includes a bidirectional manual adjustment screw with two adjustment slides fixedly connected to the two sets of adhesive removal brackets. This ensures that the two sets of pressure roller assemblies can move synchronously outwards or inwards, cooperating with the two sets of needle-type semi-cutting knives. The bidirectional manual adjustment screw, being a bidirectional screw, guarantees synchronous inward or outward movement.

[0030] Furthermore, guide rollers are also provided on the clamping bracket. For example, guide rollers are provided on both sides of the pressure roller assembly to guide the film roll.

[0031] Furthermore, at least one adhesive removal collection roller is also provided on the frame. The adhesive removal collection roller collects the used adhesive rolls, the surface of which has the removed adhesive layer.

[0032] Furthermore, the cutting and lifting assembly is a linear module arranged vertically. A slide table is installed on the linear module, and the slide table is connected to the cutting and lifting frame. A servo motor, in conjunction with a precision screw, ensures stable lifting.

[0033] Furthermore, a drive roller is embedded in the worktable, with its upper surface flush with the worktable surface. This ensures close contact between the drive roller and the worktable when the conveyor belt is pulled.

[0034] Furthermore, a brake roller is embedded in the worktable, with its upper surface flush with the worktable surface. A brake is connected to the end of the brake roller, and the brake roller and the drive roller are located on opposite sides of the worktable. This ensures active traction on one side and braking on the other, guaranteeing stable surface tension of the tape between the drive roller and the brake roller, facilitating subsequent tape discharge.

[0035] Furthermore, the drive roller is located closer to the take-up assembly, and the brake roller is located closer to the unwind assembly. This arrangement facilitates the smooth spreading of the tape on the worktable.

[0036] Furthermore, at least two photoelectric sensors are installed on the frame. These sensors, facing the tape, can detect when the tape has been used up. They are also positioned along both sides of the adhesive layer, for example, at intervals of less than 5mm. If the tape shifts during the removal process, the sensors will be triggered, allowing for timely adjustment and preventing problems during subsequent tape removal.

[0037] Furthermore, the winding assembly is a winding roller driven by a winding motor, and the unwinding assembly is an unwinding roller connected by a brake. These are common in conventional equipment and will not be described in detail here.

[0038] The beneficial technical effects of this invention are as follows: by setting up a take-up and untake-down module, the tape can be freely taken up and untaken, and the tape is spread on the worktable surface. Then, the cutting and lifting assembly moves down, so that the slitting assembly contacts the tape layer and slits the tape layer. Then, the adhesive removal and collection roller collects the slit tape layer, so that the tape layer on the surface has the required shape. When applying adhesive to precision parts, it can better adapt to the product, avoid the tedious process of applying adhesive first and then manually removing it, and also avoid the influence of the tape layer on the product, providing a reliable guarantee for the production of chips or substrates.

[0039] A method for using a partial bonding glue removal machine.

[0040] Place the tape roll: Set the tape roll on the unwinding assembly, pull the tape and wind it up by the winding assembly, and lay the tape flat on the worktable;

[0041] Tape tightening: The tightening motor drives downward, and the tightening roller of the tightening assembly moves downward and tightens the tape;

[0042] Adhesive layer cutting: The cutting lifting assembly moves downward until the slitting assembly contacts the adhesive layer, and under the drive of the bidirectional conveying module, the needle-type semi-cutting knife can move along the width direction of the tape, and when the winding assembly winds up, the needle-type semi-cutting knife can move along the length direction of the tape.

[0043] Adhesive layer removal: The cut adhesive layer is collected by an adhesive removal collection roller.

[0044] Furthermore, the cut adhesive layer is bonded by the adhesive removal roll under the pressure of the pressure roller, and the adhesive removal roll is wound around the adhesive removal collection roller to collect residual adhesive.

[0045] The beneficial technical effects of this invention are as follows: if the adhesive layer is continuous, it can be directly collected by the adhesive removal and collection roller; if the adhesive layer is discontinuous, it needs to be removed and collected by the adhesive removal roll. The continuity or discontinuity of the adhesive layer refers to whether it breaks when stretched. For example, after removing the release paper from common double-sided tape, the adhesive layer is continuous. However, common glass adhesive, even after being cut, is discontinuous and cannot be directly removed by stretching. Attached Figure Description

[0083] The semi-broken needle 533 is located inside the adjusting nut 532 and extends through the lower end of the tool housing 531 along the central axis of the tool housing 531. When cutting, the semi-broken needle 533 needs to protrude from the lower end of the tool housing 531. Of course, the length of the protruding part can be adjusted according to the thickness of the adhesive layer.

[0084] For further details, please see the appendix. Figure 10 A clamping module 6 is also provided on the frame 1. The clamping module 6 includes:

[0085] A pressing motor 61 is fixedly mounted on the frame 1 and faces downwards;

[0086] The clamping bracket 62 is connected to the lead screw and lead screw seat of the clamping motor 61; and

[0087] The clamping assembly is installed on the clamping bracket 62. Two sets of clamping assemblies are provided, and the two sets of clamping assemblies are respectively configured to cooperate with the drive roller 9 and the brake roller on the worktable 2. This ensures the clamping of the drive roller 9 and the brake roller, and also ensures the smooth discharge of adhesive by clamping the tape from top to bottom.

[0088] Furthermore, the clamping assembly includes a clamping roller 63 rotatably mounted on the clamping bracket 62. A sliding block is provided at the end of the clamping roller 63, and the sliding block is positioned within a sliding groove in the clamping bracket 62.

[0089] Furthermore, a vertical clamping guide rail and a clamping slider are provided between the clamping bracket 62 and the frame 1 to ensure smooth vertical movement between the clamping components.

[0090] For further details, please see the appendix. Figure 11 A glue removal module 7 is also provided on the clamping bracket 62. The glue removal module 7 includes:

[0091] Optical axis 71, fixedly mounted on clamping bracket 62, with film removed and mounted on optical axis 71; and

[0092] Two sets of adhesive removal brackets 72 are connected by bracket wall panels. The bracket wall panels are fixedly mounted on the pressing brackets 62. A pressure roller assembly is set on the adhesive removal brackets 72. The pressure roller 73 of the pressure roller assembly is rotated and presses the adhesive layer of the adhesive removal roll and the tape.

[0093] Furthermore, the pressure roller assembly includes a pressure roller cylinder, which is vertically downward. A pressure roller plate is provided at the end of the pressure roller cylinder, and a pressure roller 73 is rotatably mounted on the pressure roller plate. That is, secondary pressing is achieved through the pressure roller cylinder.

[0094] Furthermore, the adhesive removal bracket 72 is mounted on the bracket wall panel via a manual adjustment assembly. This assembly includes a bidirectional manual adjustment screw 74, on which two adjustment slides 75 are mounted. The two adjustment slides 75 are fixedly connected to the two sets of adhesive removal brackets 72. The bidirectional manual adjustment screw is bidirectional, ensuring that the two sets of pressure roller assemblies can move synchronously outwards or inwards, cooperating with the two sets of needle-type semi-cut knives 53.

[0095] Furthermore, guide rollers are also provided on the pressing bracket 62. For example, guide rollers are provided on both sides of the pressure roller assembly to guide the film roll.

[0096] Furthermore, at least one adhesive removal collecting roller 8 is also provided on the frame 1. The adhesive removal collecting roller 8 collects the used adhesive removal roll, the surface of which has the removed adhesive layer.

[0097] Furthermore, the cutting and lifting assembly 51 is a linear module arranged vertically. A slide table is installed on the linear module, and the slide table is connected to the cutting and lifting frame 511. A servo motor, in conjunction with a precision screw, ensures stable lifting.

[0098] Furthermore, a drive roller 9 is embedded in the worktable 2, with its upper surface flush with the surface of the worktable 2. This ensures that the drive roller 9 maintains close contact with the worktable 2 when pulling the conveyor belt.

[0099] Furthermore, a brake roller 10 is embedded in the worktable 2. The upper surface of the brake roller 10 is flush with the surface of the worktable 2. A brake is connected to the end of the brake roller 10, and the brake roller 10 and the drive roller 9 are located on opposite sides of the worktable 2. This ensures that one side provides active traction while the other side provides braking, ensuring that the conveyor belt is positioned between the drive roller 9 and the brake roller 10, facilitating subsequent glue discharge.

[0100] Furthermore, the drive roller 9 is located on the side closer to the take-up assembly 4, and the brake roller 10 is located on the side closer to the unwind assembly 3. This arrangement facilitates the smooth spreading of the tape on the worktable 2.

[0101] Furthermore, at least two photoelectric sensors are installed on the frame 1. The photoelectric sensors, facing the tape, can detect whether the tape has been used up. At the same time, the photoelectric sensors are set along both sides of the tape layer, for example, at intervals of less than 5mm. Once the tape shifts during the tape removal process, the photoelectric sensors will be triggered to make timely adjustments and avoid problems in subsequent tape removal.

[0102] Furthermore, the winding assembly 4 is a winding roller driven by a winding motor, and the unwinding assembly 3 is an unwinding roller connected to a brake. These are common in conventional equipment and will not be described in detail here.

[0103] By setting up a take-up and unwind module, the tape can be freely taken up and unwound, and spread on the surface of the worktable 2. Then, the cutting lifting component 51 moves down, so that the slitting component contacts the adhesive layer and slits the adhesive layer. Then, the adhesive removal and collection roller 8 collects the slit adhesive layer, so that the adhesive layer on the surface of the tape has the required shape. When applying adhesive to precision parts, it can better adapt to the product, avoid the tedious process of applying adhesive first and then manually removing it, and also avoid the influence of the adhesive layer on the product, providing a reliable guarantee for the production of chips or substrates.

[0104] A method for using a partial bonding glue removal machine.

[0105] Place the tape roll: Place the tape roll on the unwinding assembly 3, pull the tape and wind it up by the winding assembly 4, and lay the tape flat on the worktable 2;

[0106] Tape tightening: The tightening motor 61 drives downward, and the tightening roller 63 of the tightening assembly moves downward and tightens the tape;

[0107] Adhesive layer cutting: The cutting lifting assembly 51 moves downward until the slitting assembly contacts the adhesive layer, and under the drive of the bidirectional conveying module 52, the needle-type semi-cutting knife 53 can move along the width direction of the tape, and when the winding assembly 4 is winding, the needle-type semi-cutting knife 53 can move along the length direction of the tape.

[0108] Adhesive layer removal: The cut adhesive layer is collected by the adhesive removal collection roller 8.

[0109] Furthermore, the cut adhesive layer is bonded by the adhesive removal roll under the pressure of the pressure roller 73, and the adhesive removal roll is wound around the adhesive removal collection roller 8 to collect residual adhesive.

[0110] If the adhesive layer is continuous, it can be directly collected by the adhesive removal and collection roller 8. If the adhesive layer is discontinuous, it needs to be removed and collected by the adhesive removal roll. The continuity or discontinuity of the adhesive layer refers to whether it breaks when stretched. For example, after removing the release paper from common double-sided tape, the adhesive layer is continuous. However, common glass adhesive, even after being cut, is discontinuous and cannot be directly removed by stretching.

[0111] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
