Description

Technical Field

[0001] The utility model relates to the technical field of electronic product film pasting equipment, in particular to a flat film pasting equipment. Background Art

[0002] Electronic products can be seen everywhere in our lives, and people have higher and higher requirements for electronic products, including the appearance of electronic products. In order to ensure that electronic products will not be affected by environmental factors and cause appearance wear and tear after leaving the factory, electronic products will be treated with film.

[0003] The traditional film sticking mechanism generally includes a positioning component for fixing the workpiece and a film sticking component for sticking the film. Usually, a positioning fixture is used to fix the workpiece to be stuck with the film, and the workpiece cannot be moved or rotated after being fixed. The positioning fixture is fixed on the bracket, and the workpiece and the positioning fixture are relatively still with the bracket; it ensures that the workpiece does not shake or deviate. This fixing method can improve the accuracy of film sticking. After the workpiece is fixed, the film sticking fixture in the film sticking component absorbs the protective film, and then aligns with the workpiece to stick the protective film on the workpiece.

[0004] Although this film sticking mechanism can ensure the accuracy of film sticking, it can only stick film to one surface of the workpiece at a time, and only the surface of the workpiece facing the film sticking fixture can be stuck with film. If you want to stick film to other surfaces of the same workpiece, you can only remove the workpiece from the positioning fixture first, then adjust the other surface of the workpiece that needs to be stuck with film to the direction of the film sticking fixture, and finally place it on the positioning fixture for fixing, so that the film sticking fixture can stick film to the second surface of the workpiece. However, such operation steps are too cumbersome and seriously affect production efficiency. Utility Model Content

[0033] In this embodiment, the product 6 is an electronic product in the shape of a rectangular frame. The frame of the product 6 needs to be filmed. The frame of the product 6 is divided into a top surface 61 facing the film assembly 4 and a side surface 62 vertically connected to the top surface 61.

[0034] Please refer to Figures 1 to 5 , a flat film sticking device, used to stick a protective film 1 to a top surface 61 and a side surface 62 of a product 6, comprising:

[0035] A product positioning component 2, the product positioning component 2 is used to position a product 6;

[0036] The protective film positioning assembly 3 includes a retractable receiving member 31, and the receiving member 31 is used to lift the protective film 1 to a position facing the top surface 61, and to arrange the protective film 1 and the product 6 at a distance;

[0037] The film sticking assembly 4 is arranged on the side of the protective film 1 away from the product 6. The film sticking assembly 4 includes a first driving mechanism 41, a first mounting plate 42, a first pressing block 43, a second driving mechanism 44 and a roller 45. The first driving mechanism 41 is used to drive the first mounting plate 42 to move toward or away from the protective film 1. The first pressing block 43, the second driving mechanism 44 and the roller 45 are all connected to the first mounting plate 42 and move with the first mounting plate 42. The first pressing block 43 is arranged opposite to the receiving member 31. The second driving mechanism 44 is used to drive the roller 45 to move in a direction toward or away from the protective film 1.

[0038] When the first driving mechanism 41 drives the first mounting plate 42 to move toward the protective film 1 to a specified position, the first pressing block 43 is driven to move toward the protective film 1. The first pressing block 43 presses the protective film 1 against the receiving member 31 and presses the receiving member 31 in a retracting direction, thereby attaching the protective film 1 to the top surface 61.

[0039] Along the width direction of the product 6 , the roller 45 is in contact with the side surface 62 . When the protective film 1 is in contact with the top surface 61 , the second driving mechanism 44 drives the roller 45 to move in the direction toward the protective film 1 , thereby contacting the rest of the protective film 1 with the side surface 62 .

[0040] Please refer to Figures 1 to 5 First, the product 6 is positioned by the product positioning component 2 to prevent the product 6 from being displaced or shaken during the film application process, thereby preventing the film application position from being inaccurate. Then the protective film 1 is placed on the receiving member 31. In the initial position, the height of the receiving member 31 is greater than the height of the product 6. Therefore, after the protective film 1 is placed on the receiving member 31, the receiving member 31 will lift the protective film 1 and the product 6 to a certain distance.

[0041] In this embodiment, the frames on the left and right sides of the product 6 need to be filmed, with the left frame being taken as an example. In order to make the force on the protective film 1 more stable when the receiving member 31 holds up the protective film 1, two receiving members 31 are provided on the same side, and the two receiving members 31 are arranged along the length direction of the product 6. Then, when the protective film 1 is placed on the two receiving members 31, the top surface 61 of the frame on the same side can be covered.

[0042] After positioning the protective film 1 and the product 6, the first driving mechanism 41 is started, and the first driving mechanism 41 drives the first mounting plate 42 to move toward the product 6, thereby driving the components mounted on the first mounting plate 42 to move toward the product 6. Because the first pressing block 43 is directly opposite to the receiving member 31, the first mounting plate 42 drives the first pressing block 43 to abut against the receiving member 31. The protective film 1 is placed on the receiving member 31, so when the first pressing block 43 abuts against the receiving member 31, the protective film 1 will be pressed against the receiving member 31, forming a positioning for the protective film 1, preventing the protective film 1 from shifting during the film application process, which would result in inaccurate film application position.

[0043] Because the receiving part 31 is retractable, after the first pressing block 43 contacts the receiving part 31, the first mounting plate 42 continues to drive the first pressing block 43 to move downward, thereby pressing the receiving part 31 downward through the first pressing block 43, causing the receiving part 31 to retract. At this time, the first pressing block 43 drives the protective film 1 to continue to move downward until the lower end surface of the first pressing block 43 and the top surface 61 are in the same plane and stop moving. Then, the protective film 1 contacts the top surface 61 and fits on the top surface 61 through the clamping and driving of the first pressing block 43 and the receiving part 31.

[0044] Then the second driving mechanism 44 is started, and the second driving mechanism 44 drives the roller 45 to continue to move downward. Because the roller 45 is in contact with the side 62 in the left-right direction, the roller 45 will move along the side 62 during the downward movement of the roller 45. At this time, the protective film 1 located directly below the roller 45 is driven by the roller 45 to move downward together, and one end of the protective film 1 has been attached to the top surface 61, so the protective film 1 as a whole cannot move downward. Therefore, the part of the protective film 1 that is pressed against by the roller 45 cannot move downward either, and can only move toward the direction of the top surface 61, that is, toward the side 62, under the pressure of the roller 45. Because the roller 45 is in contact with the side 62, the roller 45 can attach the protective film 1 to the side 62.

[0045] Similarly, the structure at the right side frame and the movement of the structure are mirror-symmetrical and will not be described in detail here.

[0046] In this embodiment, through the coordinated movement of the first driving mechanism 41 and the second driving mechanism 44, the film application on the top surface 61 and the side surface 62 of the product 6 is completed in one film application process, thereby improving production efficiency and saving human resources.

[0047] In one embodiment, the film sticking assembly 4 also includes a second pressing block 46, which is fixedly connected to the first mounting plate 42. The second pressing block 46 faces the protective film 1, and the first mounting plate 42 drives the second pressing block 46 to move toward the protective film 1, thereby pressing the protective film 1 against the top surface 61 through the second pressing block 46.

[0048] like Figure 3 As shown, the second pressing block 46 is between the two first pressing blocks 43. The two first pressing blocks 43 are arranged on the front and rear sides of the product 6 along the length direction of the product 6. The second pressing block 46 is arranged directly opposite the top surface 61. Preferably, the length and width of the second pressing block 46 correspond to the length and width of the top surface 61. Because the two first pressing blocks 43 only press the two ends of the protective film 1, thereby driving the protective film 1 to fit with the top surface 61. Therefore, in this embodiment, a second pressing block 46 is also correspondingly arranged in the middle position between the two ends of the protective film 1.

[0049] When the protective film 1 contacts the top surface 61 under the clamping and driving of the first pressing block 43 and the receiving member 31, the middle part of the protective film 1 is pressed against the top surface 61 by the second pressing block 46 to ensure that the protective film 1 is completely fitted with the top surface 61. In this embodiment, the second pressing block 46 improves the fit between the protective film 1 and the top surface 61.

[0050] In one embodiment, the distance between the second pressing block 46 and the protective film 1 is smaller than the distance between the first pressing block 43 and the protective film 1 .

[0051] like Figure 1 As shown, the first pressing block 43 is closer to the protective film 1 than the second pressing block 46. Then, when the first mounting plate 42 drives the first pressing block 43 and the second pressing block 46 to move toward the protective film 1, the two first pressing blocks 43 first contact the two ends of the protective film 1, and press the protective film 1 against the receiving member 31 to form a position. Then, after the first pressing block 43 and the receiving member 31 drive the protective film 1 to the accurate position, the second pressing block 46 presses the protective film 1 against the top surface 61 to ensure the accuracy of the fitting position.

[0052] In one embodiment, the film assembly 4 also includes a first elastic member 47, both ends of which are fixedly connected to the first mounting plate 42 and the second driving mechanism 44 respectively, and the first elastic member 47 is used to drive the second driving mechanism 44 to move toward the product 6 along the width direction of the product 6.

[0053] like Figure 3As shown, a first elastic member 47 is fixedly connected to the first mounting plate 42, and the second driving mechanism 44 is connected to the first mounting plate 42 through the first elastic member 47. The first elastic member 47 is retracted in the left-right direction. Taking the left side as an example, the left end of the first elastic member 47 is fixedly connected to the first mounting plate 42, and the right end of the first elastic member 47 is connected to the second driving mechanism 44. Because the first mounting plate 42 remains relatively stationary in the left-right direction, the left end of the first elastic member 47 is a fixed end, and the right end of the first elastic member 47 is a retractable end.

[0054] In this embodiment, the right end of the first elastic member 47 continues to extend to the right, thereby driving the second drive mechanism 44 to continue to move to the right, that is, along the left-right direction, the first elastic member 47 continues to drive the second drive mechanism 44 to be close to the side 62. At the same time, along the left-right direction, the roller 45 and the second drive mechanism 44 keep moving synchronously, so the second drive mechanism 44 drives the roller 45 to be close to the side 62.

[0055] When the second driving mechanism 44 does not drive the roller 45 to move downward, the roller 45 abuts against the first pressing block 43 under the drive of the first elastic member 47, thereby preventing the roller 45 from excessively moving to the right, thereby preventing the roller 45 from abutting against the top surface 61 and being unable to continue to move downward due to the roller 45 being driven by the first elastic member 47 to move to a position directly facing the top surface 61.

[0056] When the first pressing block 43 is driven to the preset height by the first mounting plate 42, the roller 45 is driven to the preset height together with the first pressing block 43. Then the second driving mechanism 44 is started, and during the downward movement of the roller 45, the roller 45 first moves downward against the first pressing block 43. Until it moves to the same plane as the top surface 61, three situations will occur at this time, namely, the side 62 is on the left, the side 62 is in the middle, and the side 62 is on the right. Among them, the side 62 is in the middle, which is the normal situation. The roller 45 can fit the protective film 1 to the side 62 by normal downward movement.

[0057] When the side surface 62 is to the left, the roller 45 will abut against the side surface 62 when moving downward, and then needs to move leftward along the side surface 62 to complete the downward movement. Because the roller 45 and the second driving mechanism 44 are both connected to the first elastic member 47, the roller 45 can compress the first elastic member 47 to the left, thereby achieving leftward movement along the side surface 62.

[0058] When the side 62 is to the right, after the roller 45 moves downward, there is a gap between the roller 45 and the side 62, so the roller 45 cannot press the protective film 1 against the side 62. In this embodiment, the first elastic member 47 drives the roller 45 to continue to extend to the right. Before moving downward, the roller 45 abuts against the first pressing block 43 and cannot continue to move to the right. After moving downward to the same level as the side 62, because there is a gap between the roller 45 and the side 62, the first elastic member 47 continues to drive the roller 45 to move to the right until it abuts against the side 62, thereby realizing the movement of pressing the protective film 1 against the side 62.

[0059] In this embodiment, the first elastic member 47 increases the applicability of film application, and the protective film 1 can be closely attached to the side surface 62 when facing a variety of different side surfaces 62 .

[0060] In one embodiment, the product positioning assembly 2 includes a plurality of positioning blocks 21, which are arranged along the inner circle of the product 6 and are used to limit the position of the product 6. In one embodiment, the product positioning assembly 2 also includes a third driving member 22, which is connected to the positioning block 21 and is used to drive the positioning block 21 to abut against the product 6.

[0061] like Figure 5 As shown, because the product 6 in this embodiment is a rectangular frame, four positioning blocks 21 are provided. The four positioning blocks 21 are arranged along the inner frame of the product 6, and each abuts against one edge of the product 6, thereby limiting the position of the product 6. In other embodiments, the number and shape of the positioning blocks 21 can be changed according to the actual product.

[0062] At the same time, in order to enhance the applicability and positioning accuracy of the product positioning assembly 2, four positioning blocks 21 are used as an example, and two third driving members 22 are correspondingly provided. The two third driving members 22 are respectively connected to two adjacent edges, so as to limit the four directions of the product 6.

[0063] After the product 6 is placed in the product positioning assembly 2, the third driving member 22 is started, and the third driving member 22 drives the positioning block 21 connected thereto to push against the inner frame of the product 6. Figure 4 In the embodiment, the third driving member 22 on the left side drives the positioning block 21 on the left side to abut against the left side frame of the product 6, so that the right side frame of the product 6 abuts against the positioning block 21 on the right side, thereby completing the left-right direction limitation. Similarly, the same is true for the front-back direction.

[0064] In this embodiment, two third driving members 22 are used as an example, but the present invention is not limited thereto. A third driving member 22 may be arranged corresponding to each positioning block 21 for driving.

[0065] In one embodiment, the multi-angle plane film also includes a protective film clamping assembly 5, which includes an abutment block 51 and a clamping block 52. The abutment block 51 is arranged on the side of the protective film 1 facing the product 6, and the clamping block 52 is connected to the first mounting plate 42. The first mounting plate 42 is used to drive the clamping block 52 to move toward the abutment block 51, thereby pressing the protective film 1 against the abutment block 51.

[0066] like Figure 2 As shown, an abutment block 51 is also arranged directly below the protective film 1, and the abutment block 51 is arranged parallel to the frame of the product 6. And the interval between the abutment block 51 and the frame of the product 6 is greater than the diameter of the roller 45, so that the roller 45 can move downward smoothly. Corresponding to the abutment block 51, the clamping block 52 is arranged directly above the abutment block 51 and is connected to the first mounting plate 42. Driven by the first mounting plate 42, the clamping block 52 moves toward the protective film 1, thereby pressing the protective film 1 against the abutment block 51. Preferably, the length of the abutment block 51 and the clamping block 52 corresponds to the length of the frame of the product 6, so that more protective films 1 can be clamped.

[0067] In one embodiment, the receiving member 31 includes a receiving block 311 and a second elastic member 312. The receiving block 311 is used to receive the protective film 1. The second elastic member 312 is used to drive the receiving block 311 to move in a direction away from the product 6 to lift the protective film 1. In one embodiment, a guide post 313 is further provided on the surface of the receiving block 311 facing the protective film 1. The guide post 313 passes through the protective film 1 to position the protective film 1.

[0068] like Figure 2 As shown, the length of the receiving block 311 corresponds to the width of the protective film 1, and is slightly larger than the width of the protective film 1, ensuring that the protective film 1 can be fully received. The second elastic member 312 is fixedly arranged and pushes the receiving block 311 upward, so that the protective film 1 is spaced apart from the top surface 61 before the film sticking operation is performed. When the first pressing block 43 abuts against the receiving block 311, the receiving block 311 is pressed down to compress the second elastic member 312, thereby fitting the protective film 1 originally spaced apart from the top surface 61 onto the top surface 61. And after the film sticking operation is completed, the second elastic member 312 automatically pushes the receiving block 311 upward to its original height.

[0069] In this embodiment, a guide post 313 is further provided on the upper surface of the receiving block 311. Two receiving blocks 311 are arranged front and back along the length direction of the protective film 1 on the same side. Then, when both ends of the protective film 1 pass through the guide post 313 for positioning, the protective film 1 can be prevented from displacement.

[0070] In one embodiment, the receiving member 31 also includes a limiting member 32, which is disposed on the side of the receiving block 311 away from the protective film 1, and the limiting member 32 is spaced apart from the receiving block 311. When the second elastic member 312 drives the receiving block 311 to retract to a preset position, the receiving block 311 abuts against the limiting member 32.

[0071] like Figure 4 As shown, a stopper 32 is further provided below the receiving block 311, and the height of the stopper 32 corresponds to the height of the product 6 and is slightly smaller than the height of the product 6. When the receiving block 311 is pressed and moves downward, it may be over-pressed and exceed the preset position. In this embodiment, the stopper 32 is used to resist, thereby preventing the receiving block 311 from moving downward excessively.

[0072] like Figure 1 As shown, in this embodiment, two groups of positioning jigs are taken as an example, each group of positioning jigs includes a product positioning component 2, a protective film positioning component 3 and a protective film pressing component 5, and the two groups of positioning jigs are arranged at intervals. The film-applying component 4 reciprocates between the two groups of positioning jigs, so as to align with one of the groups of positioning jigs for film-applying; the positioning jig that is not aligned is manually used to take out the product 6 that has been film-applied, and to re-insert the product 6 to be film-applied and the protective film 1. In this embodiment, one film-applying component 4 corresponds to two groups of positioning jigs, which can improve work efficiency. In this embodiment, two groups of positioning jigs are taken as an example, but it is not limited to this, and the number of positioning jigs can be increased or decreased according to actual conditions.

[0073] Specifically, in this embodiment, the clamping block 52 and the first clamping block 43 are elastically connected to the first mounting plate 42, so that the clamping block 52 and the first clamping block 43 can have a buffering effect when performing a pressing action, thereby increasing the service life.

[0074] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the attached claims.
