Description

Technical Field

[0001] The present invention relates to the technical field of integrated circuit manufacturing, and more particularly to an integrated circuit cover film tearing mechanism. Background Art

[0002] The integrated circuit cover film is a protective layer covering the surface during the integrated circuit manufacturing and packaging process. It provides physical protection to avoid mechanical damage and chemical isolation to prevent oxidative corrosion. When using and installing the integrated circuit, the cover film on the surface of the integrated circuit needs to be torn off. At this time, a tearing mechanism is needed to assist in the quick tearing off of the cover film.

[0003] During the cover film removal process, the cover film adheres to the surface of the integrated circuit, creating hard contact between the two. This hard contact can easily scratch the surface of the integrated circuit, causing damage. Any minor damage to the surface of the integrated circuit can negatively impact its performance, shortening its lifespan and affecting its performance, reducing overall product quality. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention aims to provide an integrated circuit cover film tearing mechanism to solve the problem that hard contact easily leaves scratches on the surface of the integrated circuit, causing damage to the surface.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] The top end face of said sliding arm is fixedly provided with a toothed connecting strip which is cooperatively connected with the toothed connecting strip, and the bottom end face of said toothed connecting strip is connected with the toothed connecting strip by the toothed connecting gear.

[0007] Furthermore, the rear end of the tearing bin is fixedly connected to motor 1, the output shaft of motor 1 is fixedly connected to a driving screw, the driving screw is inserted into the internal thread of the sliding frame, the surface of the tearing shaft is provided with frosted particles, and a universal joint is installed between the ends of each two adjacent rotating shafts close to each other, the surface of one of the rotating shafts is fixedly sleeved with a driving gear, the output shaft of motor 2 is fixedly connected to a passive gear, and the driving gear is meshed with the passive gear.

[0008] Furthermore, a fan is fixedly connected to the upper end of the inner part of the shield.

[0009] Furthermore, a heating wire is fixedly connected to the upper end of the inner part of the shield.

[0010] Furthermore, a cutting mechanism is provided on the surface of the annular frame, and the cutting mechanism includes a supporting transverse plate fixedly connected to the outer arc surface of the annular frame, and the supporting transverse plate is rotatably connected to a connecting shaft at one end away from the annular frame, and a plurality of cutting blades are fixedly connected to the bottom end of the connecting shaft.

[0011] Furthermore, a passive transmission shaft is provided on the surface fixing sleeve of the connecting shaft, an active transmission shaft is provided on the surface fixing sleeve of one of the rotating shafts, and the active transmission shaft and the passive transmission shaft are connected via a transmission belt.

[0012] Furthermore, an adhesion mechanism is provided on the surface of the supporting cross bar, and the adhesion mechanism includes two horizontal square plates fixedly connected to the front surface of the supporting cross bar, and the surface of the horizontal square plates is slidingly sleeved with a vertical frame, and the bottom end of the vertical frame is fixedly connected to the adhesion horizontal plate, and the lower surface of the adhesion horizontal plate is fixedly connected to a rubber pad, and the lower surface of the rubber pad is fixedly connected to a plurality of adhesion thorns.

[0013] Furthermore, both ends of the adhesive horizontal plate are fixedly connected to the vertical plate, and both ends of the connecting long axis are fixedly connected to the swing arm.

[0014] Furthermore, one end of the swing arm away from the connecting long axis is rotatably connected to a driving wheel.

[0015] Furthermore, a return spring is fixedly connected to the lower surface of the horizontal plate, and the bottom end of the return spring is fixedly connected to the bottom end inside the vertical frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) This solution can tear the cover film by tearing the rubber wheel, and then use the tearing shaft to wrap the cover film and reel it up and tear it off. The cover film can be torn off without contacting the surface of the integrated circuit board, avoiding scratches and other damage to the integrated circuit during the tearing process, which will shorten the service life of the integrated circuit and reduce the use effect.

[0017] (2) This solution uses a fan to inject air into the cover film through the cracks on the surface of the cover film, causing the cover film to bulge partially, so that the tearing shaft can better contact and roll up the cover film, thereby improving the tearing effect of the cover film. When the fan transports air downward, the hot air generated by the heating wire heats the cover film, which can soften the cover film due to heat, thereby preventing the cover film from being too tough and causing the tearing rubber wheel to slip, making it difficult to tear the cover film, and further improving the tearing effect of the cover film.

[0018] (3) This solution can drive multiple cutting blades to rotate when the tearing rubber wheel rotates, so as to cut the bulges generated by the accumulation and folding of the cover film during the tearing process. It can also create a gap in the cover film when the cover film is too tough and has not been torn, so that air can be injected into the cover film. Moreover, when the cover film with a gap is wound and torn off using the tearing shaft, the cover film can be directly torn to achieve a better tearing effect.

[0019] (4) In this solution, when the tearing shaft tears off the cover film, the adhesive thorns penetrate into the cover film, and when the adhesive thorns move upward, they carry the remaining torn cover film debris away from the integrated circuit board. As the tearing shaft continues to rotate and move from front to back, the adhesive thorns move and the cover film debris is repeatedly removed, further improving the tearing effect of the cover film and reducing the debris residue during the cover film tearing process.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1-4 , an integrated circuit cover film tearing mechanism, including a tearing chamber 1, a tearing mechanism, the tearing mechanism is arranged inside the tearing chamber 1, the tearing mechanism includes a sliding frame 204 slidably connected to the top of the tearing chamber 1, the lower surface of the sliding frame 204 is fixedly connected to a connecting cross bar 215, the rear end of the connecting cross bar 215 is fixedly connected to a mask 203, the mask 203 can be used to specify the flow direction of air when the air flows subsequently, and the inner bottom end of the mask 203 is fixedly connected to a ring frame The frame 205 is fixedly connected to a plurality of connecting frames 214 on the lower surface of the annular frame 205, and a rotating shaft 207 is rotatably inserted inside the plurality of connecting frames 214. A tearing rubber wheel 206 is fixedly sleeved on the middle part of the rotating shaft 207. As the tearing rubber wheel 206 rotates, the cover film can be torn to facilitate the subsequent contactless tearing operation of the cover film. The outer arc surface of the annular frame 205 is fixedly connected to a second motor 209, which can drive the tearing rubber wheel 206 to rotate.

[0024] Among them, the lower surfaces of both ends of the connecting cross bar 215 are fixedly connected with hydraulic rods 216, and the hydraulic rods 216 can push the tearing shaft 218 to contact the cover film. The bottom end of the hydraulic rod 216 is fixedly connected with a supporting cross bar 217, and a connecting long shaft 220 is rotatably connected between the two longitudinal arm ends of the supporting cross bar 217. The surface of the connecting long shaft 220 is fixedly sleeved with a tearing shaft 218, and one end of the supporting cross bar 217 is fixedly connected with a motor 3 219, which can drive the tearing shaft 218 to wrap around the cover film and reel it up and tear it off, so as to achieve the operation of tearing off the cover film without contacting the integrated circuit board, thereby avoiding the situation where the integrated circuit board is damaged during the tearing of the cover film. The output shaft of the motor 3 219 is connected to The connecting long shaft 220 is fixedly connected, and the rear end of the tearing bin 1 is fixedly connected to the motor 1 202. The output shaft of the motor 1 202 is fixedly connected to the driving screw 201. The driving screw 201 is inserted into the internal thread of the sliding frame 204. The surface of the tearing shaft 218 is provided with frosted particles. The rough frosted particles can increase the friction when the tearing shaft 218 contacts the cover film, thereby improving the winding effect on the cover film. A universal joint 208 is installed between the ends of each adjacent two rotating shafts 207 close to each other, and a driving gear 210 is fixedly sleeved on the surface of one of the rotating shafts 207. The output shaft of the motor 2 209 is fixedly connected to the driven gear 211. The driving gear 210 is meshed with the driven gear 211 and can be used to realize power transmission.

[0025] Among them, the upper end of the inner part of the mask 203 is fixedly connected to a fan 212, and the air is injected into the cover film through the cracks on the surface of the cover film by the fan 212, so that the tearing shaft 218 can better contact and roll up the cover film, thereby improving the tearing effect of the cover film. The upper end of the inner part of the mask 203 is fixedly connected to a heating wire 213, and the cover film is heated by the heating wire 213, so that the cover film can be softened by heat, thereby preventing the cover film from being too tough and causing the tearing rubber wheel 206 to slip, making it difficult to tear the cover film.

[0026] By adopting the above technical solution, when performing the integrated circuit cover film tearing operation, the integrated circuit board is fully inserted into the tearing chamber 1, and the lower surface of the integrated circuit board is in contact with the inner bottom surface of the tearing chamber 1. Then, the second motor 209 is started, and the second motor 209 drives the rotating shaft 207 to rotate, and the power is transmitted through multiple universal shafts 208, thereby driving the tearing rubber wheel 206 to rotate. Since the tearing rubber wheel 206 has elasticity and high friction and presses on the surface of the integrated circuit board, as the tearing rubber wheel 206 rotates, the cover film on the surface of the integrated circuit can be pulled and the cover film is torn until the cover film is in a ring shape. The middle part of the shaped frame 205 is torn and stacked in the center, and at the same time, the hydraulic rod 216 is used to push the tearing shaft 218 downward until the tearing shaft 218 just contacts the surface of the cover film, and then the motor 1 202 is started, and the driving screw 201 is driven to rotate by the motor 1 202, so that the sliding frame 204 drives the tearing shaft 218 to move synchronously, and at the same time, the tearing shaft 218 is driven to rotate by the motor 3 219, so that when the rotating tearing shaft 218 contacts the torn cover film, the cover film is entangled and rolled up and torn off, and it does not contact the surface of the integrated circuit board, thereby avoiding damage to the integrated circuit during the tearing process of the cover film.

[0027] After the cover film is torn, the fan 212 can deliver air downward, so that the air is injected into the cover film through the cracks on the surface of the cover film, causing the cover film to bulge partially, so that the tearing shaft 218 can better contact and roll up the cover film, thereby improving the tearing effect of the cover film. When the fan 212 delivers air downward, the heating wire 213 can heat the air, and then heat the cover film with the hot air, so that the cover film can be softened by heat, thereby preventing the cover film from being too tough and causing the tearing rubber wheel 206 to slip, making it difficult to tear the cover film.

[0028] like Figure 4 As shown, a cutting mechanism is provided on the surface of the annular frame 205, and the cutting mechanism includes a supporting transverse plate 301 fixedly connected to the outer arc surface of the annular frame 205, and the supporting transverse plate 301 is rotatably connected to the connecting shaft 302 at one end away from the annular frame 205, and the bottom end of the connecting shaft 302 is fixedly connected to a plurality of cutting blades 303, which can cut the bulges generated by the accumulation and folding during the tearing of the cover film, and create a gap in the cover film when the cover film is not torn, so that air can be injected into the cover film, and the surface of the connecting shaft 302 is fixedly sleeved with a passive transmission shaft 304, and the surface of one of the rotating shafts 207 is fixedly sleeved with an active transmission shaft 305, and the active transmission shaft 305 and the passive transmission shaft 304 are connected by a transmission belt 306 for realizing power transmission, which can drive the plurality of cutting blades 303 to rotate.

[0029] By adopting the above technical solution, when the tearing rubber wheel 206 rotates and then tears the cover film, as the tearing rubber wheel 206 rotates, the active transmission shaft 305 also rotates with the tearing rubber wheel 206, and then power is transmitted through the transmission belt 306, which can drive the passive transmission shaft 304 to rotate, and then drive the multiple cutting blades 303 to rotate, so that the bulges accumulated and folded during the tearing process of the cover film can be cut, and a gap can be created in the cover film when the cover film is not torn, so that air can be injected into the cover film, and the cover film with a gap can be directly torn when the tearing shaft 218 is used to wrap and tear it off to achieve a better tearing effect.

[0030] like Figure 5-Figure 7 As shown, the adhesion mechanism is arranged on the surface of the supporting cross bar 217, and the adhesion mechanism includes two horizontal square plates 407 fixedly connected to the front surface of the supporting cross bar 217, and the surface of the horizontal square plate 407 is slidingly sleeved with a vertical frame 403, and the bottom end of the vertical frame 403 is fixedly connected to the adhesion horizontal plate 402, and the lower surface of the adhesion horizontal plate 402 is fixedly connected to a rubber pad. The elastic rubber pad can prevent the adhesion thorns 405 from piercing too deeply into the cover film and piercing the integrated circuit board. The lower surface of the rubber pad is fixedly connected to a plurality of adhesion thorns 405, and when the adhesion thorns 405 move upward, the residual torn cover film debris can be separated from the integrated circuit board.

[0031] Among them, both ends of the adhesion horizontal plate 402 are fixedly connected to the vertical plate 404, and both ends of the connecting long axis 220 are fixedly connected to the swing arm 401. The end of the swing arm 401 away from the connecting long axis 220 is rotatably connected to the pushing wheel 406. The pushing wheel 406 contacts and squeezes the inclined surface on the vertical plate 404, so that the adhesion thorn 405 can penetrate into the cover film. The lower surface of the horizontal plate 407 is fixedly connected to the reset spring 408. When the pushing wheel 406 is away from the surface of the vertical plate 404, the reset spring 408 can drive the adhesion horizontal plate 402 to move upward, thereby realizing the reciprocating movement of the adhesion thorn 405. The bottom end of the reset spring 408 is fixedly connected to the bottom end inside the vertical frame 403.

[0032] By adopting the above technical solution, when the tearing shaft 218 tears the cover film, the rotation of the tearing shaft 218 will drive the swing arm 401 to rotate, so that the pushing wheel 406 on the swing arm 401 contacts and squeezes the inclined surface on the vertical plate 404, causing the adhesion horizontal plate 402 to move downward. At this time, the return spring 408 is in a stretched state until the adhesion thorn 405 penetrates into the cover film. When the pushing wheel 406 is away from the surface of the vertical plate 404, the return spring 408 drives the adhesion horizontal plate 402 to move upward. Since the two sides of the lower end of the adhesion thorn 405 have inclined upward hooks, the adhesion thorn 405 can make the remaining torn cover film fragments separate from the integrated circuit board when it moves upward. In addition, as the tearing shaft 218 continues to rotate and continues to move from front to back, the adhesion thorn 405 can be moved and the cover film fragments can be repeatedly removed, thereby further improving the tearing effect of the cover film.

[0033] How to use: First, completely insert the integrated circuit board into the tear-off chamber 1, so that the lower surface of the integrated circuit board fits in with the inner bottom surface of the tear-off chamber 1; Next, the second motor 209 drives the tearing rubber wheel 206 to rotate, tearing the cover film until the cover film is torn and stacked with the middle of the annular frame 205 as the center; At the same time, the tear-off shaft 218 is pushed into contact with the surface of the cover film by the hydraulic rod 216; Next, the motor 1 202 drives the driving screw 201 to rotate, causing the sliding frame 204 to drive the tearing shaft 218 to move synchronously to coordinate with the movement of other components to complete the subsequent comprehensive tearing operation of the cover film on the surface of the integrated circuit board; At the same time, the motor 3 219 drives the tearing shaft 218 to rotate, wrapping the cover film and rewinding and tearing it off; At the same time, the fan 212 can deliver air downward, and the heating wire 213 heats the air, causing the cover film to bulge partially, so that the cover film can be torn off. At the same time, the plurality of cutting blades 303 cut the cover film to create a gap in the cover film so that air can be injected into the cover film; At the same time, the adhesive thorns 405 repeatedly penetrate the cover film during the movement process to separate the remaining torn cover film debris from the integrated circuit board, thereby improving the effect of the cover film cleaning operation; Finally, the cover film is removed.

[0034] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto.
