Description

Technical Field

[0001] The present application relates to the technical field of product processing equipment, and in particular to a film tearing head and film tearing equipment. Background Art

[0002] Some products are covered with a film during production. Some films have handles extending from the edge of the product to facilitate tearing. However, some products do not have a handle, making it difficult to tear the film using film tearing equipment. Utility Model Content

[0003] In view of this, the present application provides a film tearing head to solve the problem of low film tearing efficiency.

[0004] Embodiments of the present application provide a film peeling head comprising a film peeling member and a clamping mechanism. The film peeling member has a first end and a second end opposite each other, with an adhesive layer disposed on a side of the first end distal to the second end. The clamping mechanism is configured to clamp the second end of the film peeling member and to move the film peeling member upward and downward to bring the adhesive layer into contact with the film on the product.

[0005] In the above embodiment, the clamping mechanism clamps the mucosa piece and moves it so that the adhesive layer of the mucosa piece contacts the covering film on the product. The clamping mechanism then drives the mucosa piece to move so that the covering film is taken away from the product by the mucosa piece, thereby achieving the effect of film tearing.

[0006] In some embodiments, the film tearing head further includes a buffer mechanism, which is disposed on the clamping mechanism.

[0007] In the above embodiment, the buffer mechanism is used for buffering to avoid hard contact between the mucosa member and the product.

[0008] In some embodiments, the film tearing head also includes a pressure detection mechanism, which is connected to the clamping mechanism. The pressure detection mechanism is used to detect the pressure between the adhesive film and the product. The pressure detection mechanism is also used to send a feedback signal and stop the clamping mechanism from rising and falling.

[0009] In the above embodiment, pressure detection is performed by the pressure detection mechanism to avoid excessive pressure between the mucosa member and the product.

[0010] In some embodiments, the clamping mechanism includes a cylinder and two clamping jaws, wherein the two clamping jaws are slidably disposed on one side of the cylinder, and the cylinder is configured to drive the two clamping jaws to open or close. The cylinder is also configured to drive the two clamping jaws to move up and down.

[0011] In the above embodiment, the cylinder drives the clamping jaws to clamp the mucosa piece and drives the clamping jaws and the mucosa piece to move up and down, thereby enabling the mucosa piece to stick to the covering film and drive the covering film away from the product.

[0012] In some embodiments, the accommodating space between the two clamping jaws is used to accommodate a portion of the mucosal piece. When the clamping mechanism clamps the mucosal piece, the inner sidewall of the accommodating space contacts the mucosal piece.

[0013] In the above embodiment, the mucosal component is accommodated in the accommodating space, which helps to increase the contact area between the clamping jaws and the mucosal component.

[0014] In some embodiments, each clamping jaw is provided with a limiting portion, the limiting portion is located in the accommodating space, and the limiting portion is in contact with a side of the second end away from the first end.

[0015] In the above embodiment, the limiting portion limits the mucosal member to reduce the risk of relative displacement between the mucosal member and the clamping jaws when the mucosal member applies pressure to the covering film.

[0016] In some embodiments, the clamping mechanism further includes a limit assembly, comprising a fixing member and two limit bolts. The fixing member is connected to the cylinder and has a cavity extending vertically therethrough, within which portions of the two clamping jaws move. The two limit bolts are respectively connected to the fixing member and are located on either side of the cavity and the two clamping jaws, with each limit bolt partially extending into the cavity. The two limit bolts are used to limit the distance the two clamping jaws can open.

[0017] In the above embodiment, the limiting assembly limits the opening of the two clamping jaws to prevent the distance between the two clamping jaws from being too large.

[0018] In some embodiments, the piston of the cylinder is provided with a ferromagnetic component. The clamping mechanism further comprises a magnetic sensor movably connected to the cylinder, the magnetic sensor being used to detect the position of the ferromagnetic component on the cylinder and to send a feedback signal to the cylinder.

[0019] In the above embodiment, a magnetic sensor is used to locate the position of the piston to prevent the distance between the two clamping jaws from being too small when the two clamping jaws clamp the mucosal piece.

[0020] In some embodiments, the film tearing head further includes a mounting member connected to the clamping mechanism. The mounting member is configured to be connected to a moving mechanism and drive the clamping mechanism to move.

[0021] In the above embodiment, the mounting member is connected to the clamping mechanism and the external moving mechanism respectively, so that the mounting member drives the clamping mechanism to move.

[0022] A film tearing device comprises a moving mechanism and the above-mentioned film tearing head. The moving mechanism is connected to a clamping mechanism, and the moving mechanism is used to drive the clamping mechanism to move closer to or away from the product.

[0023] In the above embodiment, the moving mechanism drives the mounting member to move, and simultaneously drives the clamping mechanism to move, so that the clamping mechanism clamps the mucosal member to tear the film. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0049] It should be noted that when a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component. The terms "top," "upper," "lower," "front," "rear," and similar expressions used herein are for illustrative purposes only.

[0050] The terms "first", "second", etc. are only used to distinguish different objects and cannot be understood as indicating or implying relative importance or implying the quantity, specific order or primary and secondary relationship of the technical features indicated.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0052] See also Figure 1 Some products have a handle 21 on the film 20, which facilitates tearing the film 20 by clamping the handle 21. During the tearing process, the handle 21 is pulled to gradually tear the portion of the film 20 near the handle 21 away from the product, achieving the desired tearing effect. The inventors have discovered that for films 20 without a handle 21, since the film 20 is completely adhered to the product, it is impossible to clamp the film 20. Therefore, it is not convenient to use the clamping tearing method to tear the film 20 without a handle 21.

[0053] Embodiments of the present application provide a film peeling head comprising a film peeling member and a clamping mechanism. The film peeling member has a first end and a second end opposite each other, with an adhesive layer disposed on a side of the first end distal to the second end. The clamping mechanism is configured to clamp the second end of the film peeling member. The clamping mechanism is configured to move in response to an external force and to drive the film peeling member to move upward and downward, thereby bringing the adhesive layer into contact with the film on the product.

[0054] In the above embodiment, the clamping mechanism clamps the mucosa piece and moves it so that the adhesive layer of the mucosa piece contacts the covering film on the product. The clamping mechanism then drives the mucosa piece to move so that the covering film is taken away from the product by the mucosa piece, thereby achieving the effect of film tearing.

[0055] The following will describe some embodiments of the present application in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0056] An embodiment of the present application provides a film tearing device, including a moving mechanism (not shown) and a film tearing head 10. The moving mechanism drives the film tearing head 10 to move close to a product (not shown) so that the film tearing head 10 contacts the film 20 on the product. The moving mechanism then drives the film tearing head 10 to move the film 20 away from the product, thereby realizing the film tearing function.

[0057] In some embodiments, the moving mechanism is a multi-axis linear module or a robot.

[0058] In some embodiments, see Figure 2 A film tearing head 10 includes a mounting part 13, a clamping mechanism 12 and a film member 11. The top of the mounting part 13 is connected to a moving mechanism. The clamping mechanism 12 is connected to the mounting part 13. During operation, the moving mechanism drives the mounting part 13 to move, and the mounting part 13 drives the clamping mechanism 12 to move downward, so that the clamping mechanism 12 clamps the film member 11 and moves close to the product, and makes the film member 11 contact with the coating 20 on the product, so that the film member 11 sticks to the coating 20. The moving mechanism then drives the mounting part 13 to move, so that the clamping mechanism 12 drives the film member 11 away from the product, so that the film member 11 drives the coating 20 away from the product, so as to achieve the effect of tearing the coating 20 that does not contain a pull handle 21.

[0059] For example, when the product is a camera lens, the glue on the pull handle 21 is easy to stick to the lens, which can easily cause the lens to be dirty. Therefore, the film 20 on the camera lens is not provided with a pull handle 21, and the film tearing head 10 is used to tear the film of the camera lens.

[0060] The positive direction of the X-axis is the vertical upward direction, and the Y-axis and the Z-axis are both parallel to the horizontal plane.

[0061] In other embodiments, the X-axis is arranged to intersect the direction of gravity. In other embodiments, the side surface of the mounting member 13 is connected to the moving mechanism.

[0062] In some embodiments, the diameter of the bottom of the adhesive film 11 is slightly smaller than the diameter of the covering film 20 , which helps to reduce the risk of direct contact between the adhesive layer and the product.

[0063] Furthermore, when the film 20 is gradually peeled off from one side toward the center by clamping or rolling film peeling, the film 20 is locally subjected to force, and thus, during the peeling process, the film 20 can easily leave marks on the product surface, causing surface contamination. The film-sticking member 11 substantially adheres to the entire film 20, and when the clamping mechanism 12 drives the film-sticking member 11 up and down, the entire film 20 is moved away from the product in the same direction, thereby evenly separating the entire film 20 from the product. This helps reduce the risk of the film 20 leaving marks on the product surface, effectively peeling the film off products with high surface cleanliness requirements, such as camera lenses.

[0064] In some embodiments, the adhesive film member 11 can also adhere to the covering film 20 with the pull handle 21 .

[0065] In some embodiments, see Figure 3 The adhesive film member 11 has a first end 111 and a second end 112 opposite each other. An adhesive layer (not shown) is provided on the side of the first end 111 away from the second end 112. The clamping mechanism 12 clamps the second end 112 so that the first end 111 protrudes outward from the clamping mechanism 12, thereby facilitating contact between the adhesive layer on the first end 111 and the covering film 20 on the product.

[0066] In some embodiments, the film-tearing device further includes a blanking mechanism (not shown), which is disposed on one side of the moving mechanism. After the adhesive layer adheres to the covering film 20 for tearing, the moving mechanism drives the clamping mechanism 12 to move the film-sticking member 11 toward the blanking mechanism, so that the blanking mechanism picks up the covering film 20 on the adhesive layer and separates the covering film 20 from the adhesive layer, thereby allowing the film-sticking member 11 to pick up the covering film 20 again.

[0067] In some embodiments, the film-tearing device further includes a discharge mechanism (not shown) disposed on one side of the moving mechanism. As a single adhesive film member 11 sequentially adheres to multiple covering films 20, the viscosity of the adhesive layer on the adhesive film member 11 decreases. The clamping mechanism 12 releases the adhesive film member 11 and retrieves a new adhesive film member 11 from the discharge mechanism, ensuring that the adhesive film member 11 can consistently adhere to the covering films 20.

[0068] In some embodiments, see Figure 3 The clamping mechanism 12 includes a cylinder 121 and two clamping jaws 122. The cylinder 121 is connected to the mounting member 13. The two clamping jaws 122 are arranged at the bottom of the cylinder 121 and connected to the cylinder 121. The cylinder 121 drives the two clamping jaws 122 to open or close, thereby releasing or clamping the mucosal part 11.

[0069] In some embodiments, see Figure 2 and Figure 3The clamping end of the clamping claw 122 extends downward from the cylinder 121, so that the mucosa part 11 is closer to the product relative to the cylinder 121, and the cylinder 121 is away from the product, thereby reducing the obstruction of the cylinder 121 on the top of the product, thereby achieving the effect of facilitating the observation of the coating 20 on the product.

[0070] In some embodiments, the film tearing equipment also includes a positioning mechanism (not shown) provided on one side of the moving mechanism. The positioning mechanism is a CCD camera. Before tearing the film, the film 20 on the product is positioned by the positioning mechanism so that the moving mechanism can drive the film tearing head 10 to move toward the product and make the adhesive film part 11 contact with the film 20 on the product.

[0071] In some embodiments, see Figure 4 An accommodating space 1221 for accommodating the mucosal component 11 is provided between the two clamping jaws 122 .

[0072] In some embodiments, see Figure 4 A groove (not marked) is provided on the side of the clamping end of the clamping jaw 122 facing the clamping end of the other clamping jaw 122, and the groove forms a part of the accommodating space 1221. When the two clamping jaws 122 clamp the mucosa part 11 together, part of the mucosa part 11 is located inside the clamping jaw 122, and the inner wall of the groove contacts the outer side surface of the mucosa part 11, which helps to increase the contact area between the clamping jaw 122 and the mucosa part 11, thereby improving the stability of the clamping jaw 122 in clamping the mucosa part 11.

[0073] In some embodiments, when the product is a circular lens for a camera, the cover 20 corresponds to the circular shape of the lens, and the adhesive film member 11 is a cylindrical member, so that the bottom of the adhesive film member 11 can fit with the cover 20, helping the adhesive film member 11 to fully adhere to the cover 20. In this case, the horizontal cross-section of the accommodating space 1221 is semicircular.

[0074] In other embodiments, the mucosal member 11 is a columnar member with a polygonal cross section.

[0075] In some embodiments, see Figure 4 The clamping jaws 122 further include a limiting portion 1222, which is located within the accommodating space 1221. When the two clamping jaws 122 clamp the adhesive film member 11 and move it toward the product, bringing the adhesive film member 11 into contact with the product, the limiting portion 1222 contacts the top of the adhesive film member 11, allowing the clamping jaws 122 to press down the adhesive film member 11 through the limiting portion 1222. While maintaining the clamping force of the clamping jaws 122 unchanged, this helps reduce the risk of relative movement between the adhesive film member 11 and the clamping jaws 122, thereby causing the adhesive film member 11 to apply a certain amount of pressure to the product, achieving the effect of fully adhering the adhesive film member 11 to the covering film 20.

[0076] In some embodiments, see Figure 2 and Figure 3 The film peeling head 10 also includes a buffer mechanism 14, which is connected to the mounting member 13 and is located between the mounting member 13 and the moving mechanism. When the moving mechanism drives the mounting member 13 downward, so that the mounting member 13 drives the clamping mechanism 12 and the adhesive film member 11 toward the product and the adhesive film member 11 contacts the product, the buffer mechanism 14 cushions the mounting member 13, thereby preventing the risk of damage to the product caused by hard contact between the adhesive film member 11 and the product.

[0077] In some embodiments, the buffer mechanism 14 is a compression spring or elastic rubber.

[0078] In some embodiments, see Figure 2 and Figure 3 The film peeling head 10 also includes a pressure detection mechanism 15, which is connected to the mounting member 13 and is located between the mounting member 13 and the moving mechanism. When the adhesive film member 11 comes into contact with the product, the pressure detection mechanism 15 detects the pressure between the mounting member 13 and the moving mechanism. Based on the interaction of the forces, the pressure between the adhesive film member 11 and the product is determined. The pressure detection mechanism 15 then sends a feedback signal to the moving mechanism, causing the moving mechanism to stop driving the clamping mechanism 12. This helps control the pressure between the adhesive film member 11 and the product, thereby reducing the risk of product damage.

[0079] When the pressure value detected by the pressure detection mechanism 15 is greater than 0, it indicates that the adhesive film member 11 is in contact with the product and adheres to the covering film 20 .

[0080] When the adhesive membrane 11 contacts the product, the clamping mechanism 12 applies a downward pressure of less than 0.5 kPa. This helps reduce the risk of damage to the lens due to excessive pressure when the product is a camera lens. For example, the downward pressure applied by the clamping mechanism 12 on the adhesive membrane 11 is 0.05 kPa, 0.1 kPa, 0.15 kPa, 0.2 kPa, 0.25 kPa, 0.3 kPa, 0.35 kPa, 0.4 kPa, 0.45 kPa, or 0.5 kPa.

[0081] In some embodiments, the pressure detection mechanism 15 is disposed between the buffer mechanism 14 and the mounting member 13 or between the buffer mechanism 14 and the moving mechanism.

[0082] In some embodiments, the pressure detection mechanism 15 includes a pressure sensor.

[0083] In some embodiments, see Figure 2 and Figure 3The clamping mechanism 12 also includes a limiting assembly 123, which includes a fixing member 1231 and two limiting bolts 1232. The fixing member 1231 is fixed to the bottom of the cylinder 121. The fixing member 1231 is provided with a cavity 12311 extending vertically therethrough. A portion of the clamping jaw 122 extends vertically through the cavity 12311 and moves within the cavity 12311 in a third direction Z relative to the cylinder 121 and the fixing member 1231. The two limiting bolts 1232 are disposed on opposite sides of the fixing member 1231 along the opening and closing direction of the two clamping jaws 122, with portions of the limiting bolts 1232 extending within the cavity 12311. When the cylinder 121 drives the two jaws 122 to open, the two limit bolts 1232 limit the two jaws 122 respectively, thereby limiting the opening distance of the two jaws 122 to avoid the two jaws 122 from opening too far. When the adhesive force of the adhesive layer of the mucosa part 11 is insufficient, the jaws 122 can move to the discharge port of the discharge mechanism to obtain a new mucosa part 11, thereby avoiding the risk of interference between the jaws 122 and the discharge port of the discharge mechanism.

[0084] In addition, the limiting bolt 1232 is rotated to adjust the length of the limiting bolt 1232 extending into the cavity 12311, thereby changing the distance between the two limiting bolts 1232 to achieve the effect of adjusting the opening distance of the two clamping jaws 122.

[0085] In some embodiments, the cylinder 121 has two pistons (not shown) corresponding to the two clamping jaws 122, and the piston of the cylinder 121 is provided with a ferromagnetic member. Figure 2 and Figure 3 The clamping mechanism 12 also includes a magnetic sensor 124, which is arranged on the cylinder 121. When the piston of the cylinder 121 is moved by force and drives the two clamping jaws 122 to move, the magnetic sensor 124 locates the position of the piston of the cylinder 121. When the piston of the cylinder 121 moves to the detection area of ​​the magnetic sensor 124, the magnetic sensor 124 sends a feedback signal to the cylinder 121 to stop the cylinder 121 from working, thereby accurately controlling the distance between the two clamping jaws 122 to avoid the risk of clamping the mucosal part 11 due to the small distance between the two clamping jaws 122 when clamping the mucosal part 11.

[0086] In some embodiments, the magnetic sensor 124 is slidably disposed on the cylinder 121 to change the position of the detection area of ​​the magnetic sensor 124, thereby adjusting the stop position of the piston of the cylinder 121 according to the different diameters of the mucosal parts 11, so as to achieve the effect of the cylinder 121 driving the clamping jaws 122 to clamp the mucosal parts 11 with different diameters.

[0087] In addition, those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present application and are not intended to limit the present application. As long as they are within the substantive scope of the present application, appropriate changes and modifications to the above embodiments are within the scope disclosed in the present application.
