Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a sealing ring peeling mechanism and a feeding device. Background Technology

[0002] A sealing ring is a component used to prevent the leakage of liquids or gases. It is typically made of elastic materials and serves a sealing function. Sealing rings are widely used in electronic equipment. Firstly, they prevent the intrusion of external substances such as moisture and dust. Electronic equipment used outdoors or in harsh environments often requires sealing rings to prevent the intrusion of moisture, dust, and other external substances, protecting internal electrical connections from damage. Secondly, they maintain stable electrical performance. Some sealing ring materials have excellent electrical insulation properties, preventing current from flowing through the connector housing or other non-conductive parts, ensuring electrical safety. Thirdly, they reduce electromagnetic interference and radio frequency interference. In high-frequency or high-speed data transmission applications, sealing rings can also reduce electromagnetic interference and radio frequency interference, ensuring the stability of signal transmission.

[0003] In existing technologies, to improve efficiency, sealing rings are automatically fed using a feeder. The sealing ring is pre-placed on a base film and then conveyed by the feeder. To ensure adhesion of the sealing ring to the base film, grooves are formed during stamping to accommodate the sealing ring. An adhesive is then applied to the base film to allow the sealing ring to adhere better. Additionally, silicone oil is brushed onto the base film to facilitate subsequent peeling, preventing the sealing ring from becoming overly adhered. However, during silicone oil application, there may be missed areas, or the sealing ring may soften and become sticky, causing it to adhere to the base film. Sealing rings with weak bottom adhesion can be fed normally, but those with strong bottom adhesion are difficult to peel and feed properly. Extensive manual pre-peeling is required before loading the sealing rings, and the effectiveness of this pre-peeling varies greatly depending on the individual user, significantly impacting the final sealing ring application result.

[0004] Therefore, it is necessary to provide a sealing ring peeling mechanism that can effectively peel the sealing ring off the bottom film with high efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a sealing ring peeling mechanism that can automatically identify and judge and then automatically perform the power-off button operation.

[0006] Another objective of this invention is to provide a feeding device with a sealing ring peeling mechanism.

[0007] To achieve the above objectives, this utility model provides a sealing ring peeling mechanism, suitable for peeling a sealing ring off a base film, comprising:

[0008] The material stripping structure includes a material stripping cylinder, a connecting bracket, and a stripping blade. The connecting bracket is located at the output end of the material stripping cylinder, and the stripping blade is mounted on the connecting bracket. The material stripping cylinder is activated to cause the connecting bracket and the stripping blade to move downward at a first speed.

[0009] A buffer assembly is located at the lower end of the connecting bracket. The connecting bracket moves downward to abut against the buffer assembly. The buffer assembly gradually moves downward, causing the connecting bracket and the peeling blade to move downward at a second speed until the peeling blade slides along the bottom film to peel one end of the sealing ring off the bottom film.

[0010] Compared with existing technologies, the sealing ring peeling mechanism of this invention can automatically peel one end of the sealing ring off the bottom film, allowing the sealing ring to detach from the bottom film more effectively, facilitating subsequent processes. The sealing ring peeling mechanism includes a peeling structure and a buffer assembly. The peeling structure includes a peeling cylinder, a connecting bracket, and a peeling blade. The connecting bracket is located at the output end of the peeling cylinder, and the peeling blade is mounted on the connecting bracket. The peeling cylinder actuates to move the connecting bracket and the peeling blade downwards at a first speed to approach the sealing ring. The buffer assembly is located at the lower end of the connecting bracket. When the connecting bracket moves downwards to a certain position, it abuts against the buffer assembly to prevent the peeling blade from directly and rigidly impacting the feeding assembly that conveys the sealing ring. Under the pressure of the connecting bracket, the buffer assembly gradually moves downwards, causing the connecting bracket and the peeling blade to move downwards at a second speed until the peeling blade slides along the bottom film to peel one end of the sealing ring off. The buffer assembly reduces the downward speed of the peeling blade, effectively buffering the impact and preventing rigid impact. The overall structure is reasonable and reliable. The sealing ring peeling mechanism of this invention has a reasonable structure, effectively peels the sealing ring off the bottom film, and is highly efficient.

[0011] Preferably, it also includes a fixed base, the stripping cylinder is mounted on the fixed base, and a sliding component is provided between the connecting bracket and the fixed base.

[0012] Preferably, a connecting component is provided between the peeling blade and the connecting bracket, one end of the connecting component is adjustablely mounted on the connecting bracket, and the peeling blade is rotatably connected to the connecting component.

[0013] Preferably, the connecting bracket includes two sliders and a support member disposed between the two sliders. At least one slider is connected to a stripping cylinder. The connecting component is mounted on the support member, and the support member has an adjustment hole that mates with the connecting component. The connecting component moves along the adjustment hole to adjust the installation height of the stripping blade on the connecting bracket.

[0014] Preferably, the connecting assembly includes a connector and a rotating shaft, one end of the connector is connected to a connecting bracket, and the peeling blade is rotatably connected to the connector via the rotating shaft.

[0015] Preferably, a locking element is also provided between the rotating shaft and the connecting member. The locking element is released to allow the peeling blade to rotate along the rotating shaft, and the locking element is locked to position the peeling blade in a preset position.

[0016] To achieve the other objective mentioned above, the present invention also provides a feeding device, including a machine base and a feeding assembly disposed on the machine base. The feeding assembly is provided with the aforementioned sealing ring peeling mechanism. The feeding assembly includes a first straight portion, an inclined portion and a second straight portion arranged sequentially along the sealing ring conveying direction. The sealing ring peeling mechanism is disposed on the inclined portion.

[0017] Compared with existing technologies, the feeding device of this utility model is equipped with a sealing ring peeling mechanism on the machine base. During the sealing ring conveying process, the sealing ring can be effectively detached from the base film. Various types of sealing rings can be pre-peeled in advance, ensuring stable feeding and placement of the sealing rings on the feeding device. This also facilitates subsequent material handling and mounting, effectively solving the problem of manual pre-peeling. The feeding device of this utility model greatly facilitates subsequent material handling and mounting, improving efficiency.

[0018] Preferably, the inclined portion and the portion of the first straight portion near the inclined portion are provided with vacuum adsorption holes for adsorbing the bottom film.

[0028] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0029] Please see Figure 1 This invention provides a sealing ring peeling mechanism 100, suitable for peeling a sealing ring 101 off a base film 102. The sealing ring peeling mechanism 100 includes a peeling structure 10 and a buffer assembly 20. The peeling structure 10 includes a peeling cylinder 11, a connecting bracket 12, and a peeling blade 13. The connecting bracket 12 is disposed at the output end of the peeling cylinder 11, and the peeling blade 13 is mounted on the connecting bracket 12. The peeling cylinder 11 actuates to cause the connecting bracket 12 and the peeling blade 13 to move downwards at a first speed. Meanwhile, the buffer assembly 20 is disposed at the lower end of the connecting bracket 12. The connecting bracket 12 moves downwards to abut against the buffer assembly 20, and the buffer assembly 20 gradually moves downwards, causing the connecting bracket 12 and the peeling blade 13 to move downwards at a second speed until the peeling blade 13 slides along the base film 102 to peel one end of the sealing ring 101 off the base film 102. Under the action of the buffer assembly 20, the peeling blade 13 slows down, peeling the sealing ring 101 off the base film 102 with less force. The first speed is a suitable speed that is faster than the second speed, while the second speed is a slower speed. The peeling blade 13 moves down slowly to avoid rigid impact with the feeding assembly 200.

[0030] Compared with the prior art, the sealing ring peeling mechanism 100 of this utility model can automatically peel one end of the sealing ring 101 off the bottom film 102, so that the sealing ring 101 can be better separated from the bottom film 102, which facilitates the operation of subsequent processes. The sealing ring peeling mechanism 100 includes a peeling structure 10 and a buffer assembly 20. The peeling structure 10 includes a peeling cylinder 11, a connecting bracket 12, and a peeling blade 13. The connecting bracket 12 is disposed at the output end of the peeling cylinder 11, and the peeling blade 13 is mounted on the connecting bracket 12. The peeling cylinder 11 is activated to move the connecting bracket 12 and the peeling blade 13 downward at a first speed to approach the sealing ring 101. The buffer assembly 20 is disposed at the lower end of the connecting bracket 12. When the connecting bracket 12 moves downward to a certain position, it abuts against the buffer assembly 20 to prevent the peeling blade 13 from directly and rigidly impacting the feeding assembly 200 that conveys the sealing ring 101. Under the pressure of the connecting bracket 12, the buffer assembly 20 gradually moves downward, causing the connecting bracket 12 and the peeling blade 13 to move downward at a second speed until the peeling blade 13 slides along the bottom film 102 to peel one end of the sealing ring 101 off the bottom film 102. The buffer assembly 20 is used to reduce the downward movement speed of the peeling blade 13, effectively playing a buffering role and avoiding rigid impact. The overall structure is reasonable and reliable. The sealing ring peeling mechanism 100 of this utility model has a reasonable structure and can effectively peel the sealing ring 101 off the bottom film 102 with high efficiency.

[0031] Please see Figure 2 In some optional embodiments, the stripping structure 10 further includes a fixed base (not shown), which is mounted on the feeding assembly 200. The stripping cylinder 11 is mounted on the fixed base, and a sliding assembly is provided between the connecting bracket 12 and the fixed base. The stripping cylinder 11 actuates to cause the connecting bracket 12 to slide along the fixed base via the sliding assembly. The sliding assembly can be a slide rail assembly.

[0032] Please see Figure 1 and Figure 2 In some optional embodiments, a connecting assembly 14 is provided between the peeling blade 13 and the connecting bracket 12. The peeling blade 13 is connected to the connecting bracket 12 via the connecting assembly 14. Specifically, one end of the connecting assembly 14 is adjustablely mounted on the connecting bracket 12 to adjust the height of the peeling blade 13 on the feeding assembly 200. On the other hand, the peeling blade 13 is rotatably connected to the connecting assembly 14 to adjust the mounting angle of the peeling blade 13 on the connecting bracket 12, thereby enabling better peeling of various types of sealing rings 101.

[0033] Please see Figure 1 and Figure 2In some optional embodiments, the connecting bracket 12 includes two sliders and a support member disposed between the two sliders. It is understood that the sliders on both sides are slidably mounted on the feeding assembly 200 via fixed seats on both sides. Both sliders are connected to a peeling cylinder 11, and the peeling cylinders 11 on both sides operate simultaneously, causing the entire connecting bracket 12 to slide downwards simultaneously, and driving the peeling blade 13 to slide downwards. Alternatively, only one slider is connected to a peeling cylinder 11, and the peeling cylinder 11 operates to drive the connecting bracket 12 to slide downwards, and drive the peeling blade 13 to slide downwards. The connecting assembly 14 is mounted on the support member, and the support member has an adjustment hole that mates with the connecting assembly 14. The connecting assembly 14 moves along the adjustment hole to adjust the installation height of the peeling blade 13 on the connecting bracket 12, thereby adapting to different models and sizes of sealing rings 101.

[0034] Please see Figure 1 and Figure 2 In some optional embodiments, the connecting assembly 14 includes a connector and a rotating shaft. One end of the connector is connected to the support of the connecting bracket 12 and can slide within the support to adjust the installation position, thereby adjusting the installation position of the peeling blade 13. On the other hand, the peeling blade 13 is rotatably connected to the connector via the rotating shaft. Specifically, a locking member is also provided between the rotating shaft and the connector. Releasing the locking member allows the peeling blade 13 to rotate along the rotating shaft, thereby adjusting the installation angle of the peeling blade 13. Locking the locking member positions the peeling blade 13 at a preset position; that is, after adjusting the angle of the peeling blade 13, the locking member locks the peeling blade 13 onto the connecting bracket 12, thereby allowing the peeling blade 13 to peel off the sealing ring 101 at a better angle.

[0035] Please see Figure 1 and Figure 2 In some optional embodiments, the buffer assembly 20 includes a buffer cylinder 22 and a buffer member 21. The buffer member 21 is mounted at the output end of the buffer cylinder 22 and is located below the connecting bracket 12. The buffer cylinder 22 can also be mounted on a fixed base or on the feeding assembly 200. The buffer member 21 can be made of a flexible material to avoid rigid impact from the connecting bracket 12. The connecting bracket 12 moves downward to contact the buffer member 21, thereby slowing down the downward sliding speed under the action of the buffer cylinder 22, thus better acting on the sealing ring 101 on the feeding assembly 200.

[0036] Please see Figure 1To achieve the aforementioned other objective, this utility model also provides a feeding device 1000, including a machine base and a feeding assembly 200 disposed on the machine base. The feeding assembly 200 is provided with the aforementioned sealing ring peeling mechanism 100. Specifically, the feeding assembly 200 includes a first straight portion 201, an inclined portion 202, and a second straight portion 203 arranged sequentially along the conveying direction of the sealing ring 101. The sealing ring peeling mechanism 100 is disposed on the inclined portion 202.

[0037] Compared with existing technologies, the feeding device 1000 of this utility model is equipped with a sealing ring peeling mechanism 100 on its machine base. During the conveying process of the sealing ring 101, it can effectively detach the sealing ring 101 from the base film 102. Various types of sealing rings 101 can be pre-peeled in advance, ensuring that the sealing ring 101 is stably fed into place on the feeding device 1000 and facilitating subsequent auxiliary material pick-up and mounting. This effectively solves the problem of manual pre-peeling. The feeding device 1000 of this utility model greatly facilitates subsequent material picking and mounting, improving efficiency.

[0038] Please see Figure 1 In some optional embodiments, the peeling blade 13 spans across the feeding assembly 200 along its width direction. That is, the width of the peeling blade 13 and the width of the feeding assembly 200 can be slightly larger than the width of the sealing rings 101 arranged side-by-side on the bottom film 102, so that multiple sealing rings 101 on the feeding assembly 200 can be peeled off simultaneously, resulting in higher efficiency and better peeling effect. One end of the peeling blade 13 is provided with a wedge-shaped cutting edge 131 for peeling the sealing rings 101 from the bottom film 102. The wedge-shaped cutting edge 131 can better peel the sealing rings 101 from the bottom film 102. On the other hand, a guide assembly 204 is provided between the first straight portion 201 and the inclined portion 202. The guide assembly 204 includes a guide roller 2041. The bottom film 102 and the sealing rings 101 on it pass between the first straight portion 201 and the guide roller 2041, and then enter the inclined portion 202. The guide roller 2041 better guides the base film 102 and the sealing ring 101 on the base film 102 from the first straight portion 201 to the inclined portion 202. Specifically, vacuum adsorption holes for adsorbing the base film 102 are provided on the inclined portion 202 and on the portion of the first straight portion 201 near the inclined portion 202. The vacuum adsorption holes can be used to adsorb the base film 102 to prevent unstable feeding caused by the base film 102 curling up during the feeding process.

[0039] like Figures 1 to 2As shown, the feeding device 1000 of this utility model is equipped with a sealing ring peeling mechanism 100, which can peel the sealing ring 101 attached to the bottom film 102, thereby making it easier for the subsequent material picking mechanism to pick up the sealing ring 101 for subsequent installation processes. The sealing ring peeling mechanism 100 includes a peeling structure 10 and a buffer assembly 20. The peeling structure 10 includes a peeling cylinder 11, a connecting bracket 12, and a peeling blade 13. The connecting bracket 12 is located at the output end of the peeling cylinder 11, and the peeling blade 13 is mounted on the connecting bracket 12. The peeling cylinder 11 is activated to move the connecting bracket 12 and the peeling blade 13 downward at a first speed to approach the sealing ring 101. The buffer assembly 20 is located at the lower end of the connecting bracket 12. When the connecting bracket 12 moves downward to a certain position, it abuts against the buffer assembly 20 to prevent the peeling blade 13 from directly and rigidly impacting the feeding assembly 200 that conveys the sealing ring 101. Under the pressure of the connecting bracket 12, the buffer assembly 20 gradually moves downward, causing the connecting bracket 12 and the peeling blade 13 to move downward at a second speed until the peeling blade 13 slides along the bottom film 102 to peel one end of the sealing ring 101 off the bottom film 102. Then, the peeling blade 13 resets, and the bottom film 102 and the peeled sealing ring 101 continue to be conveyed. A new row of sealing rings 101 is conveyed to the vicinity of the peeling blade 13, and the peeling blade 13 slides downward again to peel one end of the sealing ring 101 off the bottom film 102. The buffer assembly 20 reduces the downward speed of the peeling blade 13, effectively buffering the movement and avoiding rigid impact. The overall structure is reasonable and reliable. The sealing ring peeling mechanism 100 of this utility model has a reasonable structure, effectively peels the sealing ring 101 off the bottom film 102, and is highly efficient.

[0040] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall fall within the scope of the present utility model.
