Description

Technical Field

[0001] This invention relates to the field of film application equipment technology, and particularly to a film application mechanism and film application equipment. Background Technology

[0002] During the production and assembly process, products generally require many steps and need to be transferred between different workstations. To avoid defects caused by surface scratches during the transfer of the product shell, a protective film is often applied to the shell surface for protection. However, the existing film-applying mechanisms for curved surfaces do not have good film-applying effects, and air bubbles or wrinkles are prone to appear on the inside of the protective film. Summary of the Invention

[0003] The main objective of this invention is to provide a film application mechanism that improves the film application effect.

[0004] To achieve the above objectives, the present invention proposes a film-applying mechanism for applying a film to the surface of a product to be processed. The film-applying mechanism includes:

[0005] Base;

[0006] A first driving device is used to drive the base to move along a first direction; and

[0007] A film-applying assembly is installed on the base. The film-applying assembly includes a pressing member and a film-applying member. The pressing member is used to press the protective film at the starting position of the film application on the surface to be processed. The film-applying member includes an action part that can engage with the surface to be processed to press the protective film onto the surface to be processed.

[0008] In one embodiment, the actuating part is provided with a shaping groove, and the actuating part engages with the surface to be processed through the shaping groove.

[0009] In one embodiment, the pressing member is slidably mounted on the base in a first direction, and at least the actuating part is movable relative to the base in a second direction, wherein the first direction and the second direction form an angle.

[0010] The film application assembly further includes a first elastic element and a second elastic element mounted on the base, wherein the first elastic element acts on the pressing element in the first direction;

[0011] The second elastic member acts on the film-coating member, such that when the actuating part is in the initial position, the actuating part can abut against the side of the pressing member in the second direction. After the pressing member presses the protective film at the film-coating starting position, the actuating part can scrape the protective film along the surface to be processed until the actuating part engages with the film-coating ending position on the surface to be processed.

[0012] In one embodiment, the coating is rotatably mounted on the base.

[0013] In one embodiment, the coating member includes a first arm and a second arm located on both sides of the rotation center, the actuating part is disposed on the first arm, and the second elastic member acts on the second arm in the second direction.

[0014] In one embodiment, the actuating portion protrudes from the side of the coated member near the pressing member;

[0015] And / or, the actuating part has an arc surface on the side near the pressing member.

[0016] In one embodiment, the film-applying mechanism further includes a second driving device, which is mounted on the base and driven to be connected to the film-applying member, for driving the actuating part to move away from the pressing member.

[0017] In one embodiment, the coating member is rotatably mounted on the base, and the coating member includes a first arm and a second arm located on both sides of the rotation center, and the working part is disposed on the first arm.

[0018] The film-applying components are arranged side by side along the second direction, and the second driving device drives the connecting push part to push against the second arm of the film-applying component located on the side in the second direction along the second direction.

[0019] Between two adjacent coating members, a transmission part is provided on the second arm of the coating member closer to the pushing part, the transmission part being used to push against the second arm of the other coating member.

[0020] The present invention also proposes a film-applying device, including a frame, a fixture, and the aforementioned film-applying mechanism. The fixture and the film-applying mechanism are respectively disposed on the frame. The fixture is used to fix the product, and the film-applying mechanism is used to press the protective film onto the surface to be processed.

[0021] In one embodiment, the film application equipment further includes a film supply unit, a film dispensing mechanism, an upper film application mechanism, and a lower film application mechanism, each respectively disposed on the frame;

[0022] The film-taking mechanism is used to attach the protective film on the film-supplying component to the film-attaching starting position of the surface to be processed. The protective film has a first covering section and a second covering section connected to each other. The surface to be processed includes a first processing section and a second processing section.

[0023] The upper film-applying mechanism is configured as the film-applying mechanism. The first driving device of the upper film-applying mechanism drives the base of the upper film-applying mechanism to move downwards, so as to press the first covering section onto the first processing section through the working part of the upper film-applying mechanism.

[0024] The lower film application mechanism is configured as the film application mechanism. The first driving device of the lower film application mechanism drives the base of the lower film application mechanism to move upward, so as to press the second covering section onto the second processing section through the working part of the lower film application mechanism, so that the protective film covers the surface to be processed around the entire circle.

[0025] In one embodiment, the film application device further includes a conveying mechanism, which includes a conveyor belt, a return belt, a transfer structure, and a handling component, wherein the return belt and the transfer structure are located on opposite sides of the conveyor belt in the width direction.

[0026] The upper film-applying mechanism is configured corresponding to the conveyor belt, the lower film-applying mechanism is configured corresponding to the transfer structure, and the conveying assembly is used to move the tooling from the conveyor belt to the transfer structure and to move the tooling from the transfer structure to the return belt.

[0027] The technical solution of this invention involves mounting a film-applying assembly onto a base and using a first driving device to drive the base to move along a first direction. Specifically, the surface of the product to be processed is located in the first direction. When the first driving device drives the base to move along the first direction, a pressing member on the base presses the protective film at the starting point of the film application on the surface to be processed. That is, the pressing member presses the protective film and the product at the starting point of the film application on the surface to be processed, thereby preventing displacement of the protective film and / or the product during the application process, and preventing relative displacement between the actuating part and the surface to be processed. This ensures the effective fit of the actuating part with the surface to be processed, thus improving the film application effect. Furthermore, when the actuating part engages with the surface to be processed, it can further press the protective film onto the surface to be processed, eliminating air bubbles or wrinkles on the inner side of the protective film, thereby further improving the film application effect.

[0040] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0042] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0043] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0044] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0045] During the production and assembly process, products generally require many steps and need to be transferred between different workstations. To avoid defects caused by surface scratches during the transfer of the product shell, a protective film is often applied to the shell surface for protection. However, the existing film-applying mechanisms for curved surfaces do not have good film-applying effects, and air bubbles or wrinkles are prone to appear on the inside of the protective film.

[0046] This invention proposes a film application mechanism 100.

[0047] Reference Figure 2 Figure 4 In one embodiment of the present invention, the film-applying mechanism 100 is used to apply a film to the surface 21 of the product 20 to be processed. The film-applying mechanism 100 includes a base 110, a first driving device 120, and a film-applying assembly 130. The first driving device 120 is used to drive the base 110 to move along a first direction. The film-applying assembly 130 is mounted on the base 110. The film-applying assembly 130 includes a pressing member 131 and a covering member 132. The pressing member 131 is used to press the protective film 30 at the film-applying starting position 22 on the surface 21 to be processed. The covering member 132 includes an action part 132a. The action part 132a can engage with the surface 21 to press the protective film 30 onto the surface 21 to be processed.

[0048] The technical solution of the present invention involves mounting the film-applying assembly 130 on the base 110 and using the first driving device 120 to drive the base 110 to move along the first direction. This allows the film-applying assembly 130 to move along the first direction. Specifically, the surface 21 of the product 20 to be processed is located in the first direction. When the first driving device 120 drives the base 110 to move along the first direction, the pressing member 131 on the base 110 presses the protective film 30 at the film-applying starting position 22 on the surface 21 to be processed. That is, the pressing member 131 presses the protective film 30 and the product 20 at the film-applying starting position 22 on the surface 21 to be processed, thereby preventing the protective film 30 and / or the product 20 from shifting during the film-applying process and preventing relative displacement between the active part 132a and the surface 21 to be processed. This ensures the cooperation effect of the active part 132a with the surface 21 to be processed, thereby improving the film-applying effect. Furthermore, when the actuating part 132a engages with the surface 21 to be processed, the actuating part 132a can further press the protective film 30 onto the surface 21 to be processed, thereby eliminating air bubbles or wrinkles on the inner side of the protective film 30, and thus further improving the film application effect.

[0049] The function 132a can engage with the surface 21 to be processed. This can be understood as follows: when the surface 21 to be processed is convex, the function 132a is provided with a shape-adaptive shaping groove 132a1; when the surface 21 to be processed is concave, the function 132a is provided with a shape-adaptive shaping protrusion.

[0050] Optionally, the actuating part 132a is provided with a shaping groove 132a1. The actuating part 132a engages with the surface 21 to be processed through the shaping groove 132a1. It can be understood that when the shaping groove 132a1 engages with the surface 21 to be processed, the groove wall of the shaping groove 132a1 can further press the protective film 30 onto the surface 21 to be processed, thereby eliminating air bubbles or wrinkles on the inner side of the protective film 30, and thus further improving the film application effect. Of course, this solution is not limited to this. In other embodiments, if the surface 21 to be processed is concave, the actuating part 132a is provided with a shaping protrusion with a matching shape.

[0051] It should be noted that the surface to be processed 21 can be a curved surface, such as an arc surface, and the shape of the forming groove 132a1 is correspondingly arc-shaped; the surface to be processed 21 can also have corners, for example, the surface to be processed 21 is a circumferential side of a prism, pyramid or other structure, and corners will be formed at the positions of each edge, and the forming groove 132a1 engages with the corners.

[0052] In this embodiment, the shaping groove 132a1 is adapted to the shape of the surface 21 to be processed. This allows the shaping groove 132a1 to engage with the surface 21 to be processed, thereby clamping the protective film 30 onto the surface 21 and smoothing it out. This eliminates air bubbles or wrinkles on the inner side of the protective film 30, further improving the film application effect.

[0053] Reference Figure 3 Optionally, in this embodiment, the pressing member 131 is slidably mounted on the base 110 in a first direction, and at least the actuating part 132a is movable relative to the base 110 in a second direction, the first direction and the second direction forming an angle; the film-applying assembly 130 further includes a first elastic member 133 and a second elastic member 134 mounted on the base 110, the first elastic member 133 acting on the pressing member 131 in the first direction; the second elastic member 134 acting on the film-covering member 132, such that when the actuating part 132a is in the initial position, the actuating part 132a can abut against the side of the pressing member 131 in the second direction, and when the pressing member 131 presses the protective film 30 at the film-applying starting position 22, the actuating part 132a can scrape the protective film 30 along the surface to be processed 21 until the actuating part 132a engages with the film-applying ending position 23 of the surface to be processed 21.

[0054] It is understood that when the actuating part 132a is in the initial position, that is, when the film-applying assembly 130 is not acting on the product 20, the actuating part 132a abuts against the side of the pressing member 131 in the second direction; the first driving device 120 drives the base 110 to move in the first direction, and the pressing member 131 will first abut against the protective film 30 at the film-applying starting position 22 on the surface to be processed 21, that is, the pressing member 131 will first abut against the protective film 30 and the product 20 at the film-applying starting position 22 on the surface to be processed 21, so as to ensure that the protective film 30 and / or the product 20 will not undergo relative displacement. The first driving device 120 continues to drive the base 110 to move in the first direction, and the pressing member 131 will slide in the opposite direction of the driving direction of the first driving device 120 under the reaction force of the product 20, thereby acting on the first elastic member 133, and the pressing member 131 elastically presses the product 20 and the protective film 30 under the elastic force of the first elastic member 133. Since the pressing member 131 slides in the opposite direction to the driving direction of the first driving device 120, the action part 132a will disengage from the pressing member 131. After the action part 132a disengages from the pressing member 131, the film-coating member 132 will be pressed onto the surface to be processed 21 under the elastic restoring force of the second elastic member 134. Under the action of the first driving device 120 and the second elastic member 134, it will move in the first direction and scrape along the surface to be processed 21 until it reaches the film-coating endpoint position 23. In other words, under the elastic restoring force of the second elastic member 134, the coating member 132 causes the actuating part 132a to move towards the pressing member 131 to scrape and press the surface to be processed 21. When the actuating part 132a reaches the film application endpoint position 23, the actuating part 132a engages with the film application endpoint position 23 of the surface to be processed 21. That is, the shaping groove 132a1 engages with the film application endpoint position 23 of the surface to be processed 21, thereby further pressing the protective film 30 onto the surface to be processed 21, which can further improve the stability and effect of film application.

[0055] It should be noted that in this solution, the first direction is the up-down direction, but in other embodiments, it can be other directions, such as the left-right direction. The second direction is the left-right direction, but in other embodiments, it can be other directions, such as the front-back direction.

[0056] In this design, when the active part 132a is in the initial position, it abuts against the side of the pressing member 131 in the second direction. This can prevent the active part from exceeding the film application starting position 22 and interfering with the product 20 under the action of the second elastic member 134.

[0057] Reference Figure 4It should be noted that the film application start position 22 and film application end position 23 refer to one film application action of the film application component 130, rather than the complete film application process of the surface to be processed 21.

[0058] Reference Figure 2 and Figure 5 Furthermore, the coating member 132 is rotatably mounted on the base 110. It can be understood that the second elastic member 134 acts on the coating member 132. When the actuating part 132a disengages from the pressing member 131, the coating member 132 will rotate under the action of the second elastic member 134, thereby causing the actuating part 132a to press against the surface to be processed 21. When the first driving device 120 continues to drive the substrate to move in the first direction, that is, towards the product 20, the actuating part 132a can run along the surface to be processed 21 to scrape the protective film 30 onto the surface to be processed 21. The coating member 132 designed in this way allows the actuating part 132a to automatically fine-tune the angle of the coating member 132 during the scraping process to adapt to the unevenness of the surface to be processed 21 under the protective film 30 and the change of operating force, thereby further improving the film application effect. Of course, this solution is not limited to this. In other embodiments, the coating member 132 is slidably disposed along the second direction, and the second elastic member 134 acts on the coating member 132 in the second direction so that the actuating part 132a has a tendency to move closer to the pressing member 131.

[0059] In this embodiment, the first elastic element 133 and the second elastic element 134 are configured as return springs. However, this solution is not limited to this; in the second embodiment, the first elastic element 133 and the second elastic element 134 can also be configured as elastic sheets. Furthermore, this solution is not limited to this; in the third embodiment, the first elastic element 133 can be configured as a return spring, and the second elastic element 134 can be configured as an elastic sheet. No specific configuration of the first elastic element 133 and the second elastic element 134 is limited here.

[0060] Furthermore, the pressing member 131 is provided with a pressing groove corresponding to the product 20. The pressing groove is used to place part of the outer peripheral surface of the product 20, which can increase the stability of the pressing member 131 pressing the product 20.

[0061] Optionally, the coating component 132 includes a first arm 132b and a second arm 132c located on both sides of the rotation center. The actuating part 132a is disposed on the first arm 132b, and the second elastic element 134 acts on the second arm 132c in the second direction. It can be understood that by adjusting the length ratio (lever arm) of the first arm 132b and the second arm 132c, the force and the displacement of the second arm 132c can be amplified or reduced. Furthermore, the second elastic element 134 acting on the second arm 132c is equivalent to applying a continuous and stable reverse force or preload to the actuating part 132a (first arm 132b) through a lever. This preload is then used to scrape and press the protective film 30 onto the surface 21 to be processed. Moreover, this design separates the force application point (second elastic element 134) and the actuating point (actuating part 132a) on both sides of the fulcrum, making the force on the coating component 132 (lever) more balanced and avoiding distortion caused by unilateral force. Of course, this solution is not limited to this. In other embodiments, the coating member 132 has only an arm extending from one side of the rotation center, the action part 132a is provided on the arm, the second elastic member 134 acts directly on the arm, or the second elastic member 134 is configured as a torsion spring and the torsion spring is provided at the rotation center.

[0062] Furthermore, the substrate is provided with a first mounting block corresponding to the first elastic member 133, one end of the first elastic member 133 is connected to the first mounting block, and the other end is connected to the pressing member 131. The substrate is provided with a second mounting block corresponding to the second elastic member 134, one end of the second elastic member 134 is connected to the second mounting block, and the other end is connected to the second arm 132c.

[0063] Optionally, the actuating part 132a protrudes from the side of the coating member 132 near the pressing member 131, effectively forming a hook structure. This reduces the contact area between the coating member 132 and the pressing member 131, thereby reducing the resistance encountered by the actuating part 132a when sliding along the surface of the pressing member 131. Of course, this solution is not limited to this. In other embodiments, the end of the coating member 132 can directly serve as the actuating part 132a without forming a hook structure.

[0064] In this embodiment, the shaping groove 132a1 is located on the side of the actuating part 132a away from the end face of the coating member 132. This makes it easier for the shaping groove 132a1 to engage with the entire surface 21 to be processed when the actuating part 132a reaches the film application endpoint position 23. Of course, this solution is not limited to this. In other embodiments, the shaping groove 132a1 can also be located on the side of the actuating part 132a facing the end face of the coating member 132.

[0065] Optionally, the actuating part 132a has an arc surface 132a2 on the side near the pressing member 131. Without the arc surface 132a2 (i.e., a right-angled edge), when the actuating part 132a separates from the pressing member 131 and begins to scrape the film, its edge will suddenly and completely contact the protective film 30. This can easily cause the pressure to be concentrated on a sharp line, which may damage the film material or even cause operational difficulties due to sudden changes in resistance. Of course, this solution is not limited to this. In other embodiments, the actuating part 132a has a slope on the side near the pressing member 131.

[0066] In this embodiment, the curved surface 132a2 is a circular arc surface, which can further improve the film application effect.

[0067] Optionally, the film-applying mechanism 100 further includes a second driving device 140, which is mounted on the base 110 and driven and connected to the film-applying member 132. The second driving device 140 drives the actuating part 132a to move away from the pressing member 131. It can be understood that when the actuating part 132a reaches the film-applying endpoint position 23, the shaping groove 132a1 engages with the film-applying endpoint position 23 of the surface to be processed 21. If the first driving device 120 is directly used to move away from the product 2... If the actuating part 132a moves in the direction of 0, it is easy for the actuating part 132a to scrape the protective film 30 in the opposite direction, causing the protective film 30 adhering to the surface 21 to be processed to detach from the surface 21. This solution provides a second driving device 140 to drive the film-coating member 132 to move the actuating part 132a away from the pressing member 131, that is, to drive the actuating part 132a to detach from the surface 21 to be processed of the product 20. This can prevent the protective film 30 adhering to the surface 21 to be processed from detaching from the surface 21 to be processed. Of course, this solution is not limited to this. In other embodiments, the second driving device 140 may not be provided. Instead, a guide slope may be provided on the actuating part 132a. When the first driving device 120 drives the base 110 in a direction away from the product 20, the actuating part 132a gradually moves along the surface 21 to be processed under the action of the guide slope, so that the actuating part 132a can safely detach from the surface 21 to be processed.

[0068] It should be noted that when the actuating part 132a moves to the film application endpoint position 23, the shaping groove 132a1 engages with the film application endpoint position 23 of the surface to be processed 21. The second driving device 140 drives the film-coating member 132 to move the actuating part 132a away from the pressing member 131, thereby causing the actuating part 132a to disengage from the surface to be processed 21. Then, the first driving device 120 drives the base 110 to move away from the product 20. Under the action of the first elastic member 133, the pressing member 131 pushes against the film application start position of the surface to be processed 21 while sliding towards the product 20, thereby returning to the initial position. At the same time, the film-coating member 132 also returns to the initial position, so that the actuating part 132a pushes against the side of the pressing member 131 again in the second direction.

[0069] The film-coated member 132 returning to its initial position can be achieved by the second driving device 140 driving the film-coated member 132 in a direction opposite to the driving state that drives the actuating part 132a to move away from the pressing member 131, thereby causing the second driving device 140 to drive the film-coated member 132 back to its original state. Alternatively, when the force of the second driving device 140 is removed, the film-coated member 132 returns to its original state under the elastic restoring force of the second elastic member 134.

[0070] In this example, the first drive device 120 and the second drive device 140 are configured as motors or cylinders. Of course, in other embodiments, the first drive device 120 and the second drive device 140 may also be configured as a drive motor plus a transmission module. No specific limitations are made on the first drive device 120 and the second drive device 140 here.

[0071] Further, in this embodiment, the film-coating component 132 is rotatably mounted on the base 110. The film-coating component 132 includes a first arm 132b and a second arm 132c located on both sides of the rotation center, and the actuating part 132a is provided on the first arm 132b. Multiple film-applying assemblies 130 are arranged side by side along the second direction. The second driving device 140 drives and connects to the pushing part 141, which is used to drive the pushing part 141 to push against the second arm 132c of the film-coating component 132 located on the side in the second direction. Between two adjacent film-coating components 132, the second arm 132c of the film-coating component 132 closer to the pushing part 141 is provided with a transmission part 132d, which is used to push against the second arm 132c of the other film-coating component 132.

[0072] It is understood that in this embodiment, the second driving device 140 drives the pushing part 141, which pushes the second arm 132c of the coating member 132 located on the side in the second direction. So that between two adjacent coating members 132, the transmission part 132d on the second arm 132c of the coating member 132 closer to the pushing part 141 will push the second arm 132c of the coating member 132 further away from the pushing part 141, thereby causing multiple coating members 132 to rotate simultaneously. This causes the action part 132a on each coating member 132 to move away from the pressing member 131. This scheme of using one second driving device 140 to link multiple coating members 132 can save the setting of a driving device and help reduce production costs. Of course, this solution is not limited to this. Multiple push plates can also be connected to the second drive device 140, that is, one push plate corresponds to one coating component 132. In this way, one second drive device 140 can drive multiple coating components 132 to rotate.

[0073] In this embodiment, the pushing part 141 is movably abutted against the second arm 132c of the coating member 132 located on the side in the second direction. That is, the pushing part 141 and the second arm 132c of the coating member 132 are not connected. Only when the second driving device 140 drives the pushing plate to move towards the product 20 will the pushing part 141 push against the second arm 132c of the coating member 132 located on the side in the second direction, so that the second arm 132c moves towards the product 20, thereby causing the action part 132a provided on the first arm 132b to move away from the pressing member 131. When the second drive device 140 drives the push plate to move towards the product 20, the force exerted by the push part 141 on the second arm 132c is removed. Under the action of the second elastic member 134, the second arm 132c also moves away from the product 20. This causes the action part 132a provided on the first arm 132b to move towards the pressing member 131, thereby causing the action part 132a to abut against the side of the pressing member 131 again.

[0074] In this embodiment, multiple film-applying components 130 are arranged side-by-side along the second direction, allowing for simultaneous film application to multiple products 20, thus improving application efficiency. Further, in this embodiment, the product 20 is an earphone, and two film-applying components 130 are arranged side-by-side along the second direction. One component applies film to the left earphone, and the other applies film to the right earphone. Alternatively, both components 130 can apply film to either the right or left earphone. This solution is not limited to this; in other embodiments, four or six film-applying components 130 are arranged side-by-side along the second direction.

[0075] Reference Figure 1 ,and Figures 3 to 6 The present invention also proposes a film-applying device 10, which includes a frame 200, a fixture 300, and the aforementioned film-applying mechanism 100. The specific structure of the film-applying mechanism 100 is as described in the above embodiments. Since the film-applying device 10 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The fixture 300 and the film-applying mechanism 100 are respectively disposed on the frame 200. The fixture 300 is used to fix the product 20, and the film-applying mechanism 100 is used to press the protective film 30 onto the surface 21 to be processed.

[0076] Optionally, in this embodiment, the film application device 10 further includes a film supply component 500, a film taking mechanism 600, an upper film application mechanism 910, and a lower film application mechanism 920 respectively disposed on the frame 200; the film taking mechanism 600 is used to attach the protective film 30 on the film supply component 500 to the film application starting position 22 of the surface to be processed 21, the protective film 30 having a first covering section and a second covering section connected to each other, and the surface to be processed 21 including a first processing section and a second processing section; the upper film application mechanism 910 is configured as the film application mechanism 100, and the upper film application mechanism 910 has a first covering section and a second covering section connected to each other. A driving device 120 drives the base 110 of the upper film-applying mechanism 910 to move downwards, so as to press the first covering section onto the first processing section through the working part 132a of the upper film-applying mechanism 910; the lower film-applying mechanism 920 is configured as the film-applying mechanism 100, and the first driving device 120 of the lower film-applying mechanism 920 drives the base 110 of the lower film-applying mechanism 920 to move upwards, so as to press the second covering section onto the second processing section through the working part 132a of the lower film-applying mechanism 920, so that the protective film 30 covers the entire surface 21 to be processed. Of course, this solution is not limited to this. In other embodiments, the film application device 10 also includes a film supply component 500, a film taking mechanism 600, a left film application mechanism, and a right film application mechanism. The left film application mechanism is configured as the film application mechanism. The first driving device 120 of the left film application mechanism drives the base 110 of the left film application mechanism to move to the right, so as to press the first covering section onto the first processing section through the working part 132a of the left film application mechanism. The right film application mechanism is configured as the film application mechanism 100. The first driving device 120 of the right film application mechanism drives the base 110 of the right film application mechanism to move to the left, so as to press the second covering section onto the second processing section through the working part 132a of the right film application mechanism, so that the protective film 30 covers the entire surface 21 to be processed.

[0077] Specifically, after the film-taking mechanism 600 attaches the protective film 30 from the film-supplying member 500 to the film-attaching starting position 22 of the surface to be processed 21, the first driving device 120 of the upper film-attaching mechanism 910 drives the base 110 to move in the first direction, so that the pressing member 131 of the upper film-attaching mechanism 910 presses the protective film 30, and the first covering section is pressed onto the first processing section through the working part 132a of the upper film-attaching mechanism 910. Then, the first driving device 120 of the lower film-attaching mechanism 920 drives the base 110 to move in the first direction, so that the pressing member 131 of the lower film-attaching mechanism 920 presses the protective film 30, and the second covering section is pressed onto the second processing section through the working part 132a of the lower film-attaching mechanism 920.

[0078] It should be noted that in this solution, the first direction is the up-down direction, but in other embodiments, it can be other directions, such as the left-right direction. The second direction is the left-right direction, but in other embodiments, it can be other directions, such as the front-back direction.

[0079] Reference Figure 1 ,and Figures 7 to 9 Furthermore, the film-applying device 10 also includes a conveying mechanism 400, which includes a conveyor belt 410, a return belt 420, a transfer structure 432, and a transport assembly 430. The return belt 420 and the transfer structure 432 are located on opposite sides of the width of the conveyor belt 410. The upper film-applying mechanism 910 is configured corresponding to the conveyor belt 410, and the lower film-applying mechanism 920 is configured corresponding to the transfer structure 432. The transport assembly 430 is used to transport the tooling 300 from the conveyor belt 410 to the transfer structure 432, and to transport the tooling 300 from the transfer structure 432 to the return belt 420. Of course, this solution is not limited to this. In other embodiments, the conveying mechanism 400 may not be provided, and the product 20 may be applied at the same position.

[0080] The film application equipment 10 also includes a positioning mechanism and a clamping mechanism 800. When the conveyor belt 410 conveys the product 20 tooling 300 with the protective film 30 to the position of the upper film application mechanism 910, the positioning mechanism lifts up and fixes the tooling 300, thereby preventing the tooling 300 from moving when the upper film application mechanism 910 applies the film to the surface 21 of the product 20 to be processed, thus preventing the product 20 with the protective film 30 from moving, which helps to ensure the orderly progress of the film application process. Next, the upper film-applying mechanism 910 applies film to the first processing section. When the actuating part 132a of the upper film-applying mechanism 910 presses the first covering section onto the first processing section, the film-applying operation of the first processing section is completed. The transport component 430 transports the product 20 fixture 300 with the completed film-applying operation of the first processing section to the transfer structure 432. The transfer structure 432 transfers the fixture 300 to the corresponding position of the film-applying mechanism 100. Then, the clamping mechanism 800 presses the fixture 300 to prevent the fixture 300 from shaking. Next, the lower film-applying mechanism 920 applies film to the second curved surface. After the actuating part 132a of the lower film-applying mechanism 920 presses the second covering section onto the second curved surface, the transport component 430 transports the film-applied product 20 fixture 300 to the return belt 420. The return belt 420 carries away the completed product 20 fixture 300 for the next process.

[0081] It is understood that the film application equipment 10 includes an upper film application mechanism 910 and a lower film application mechanism 920. That is, the film application equipment 10 is provided with two film application mechanisms 100. Of course, this solution is not limited to this. In other embodiments, there may be only one film application mechanism 100 or four film application mechanisms 100, which are evenly distributed around the surface 21 to be processed.

[0082] It should be noted that the up and down directions mentioned in this invention are all based on the ground. The direction facing the ground is downward, that is, the side of the relevant structure facing the ground corresponds to its lower side, and the direction away from the ground is upward, that is, the side of the relevant structure away from the ground corresponds to its upper side.

[0083] In this design, the return belt 420 and the conveyor belt 410 are arranged parallel to each other. The handling component 430, the film supply component 500, the film taking mechanism 600, the clamping mechanism 800, the upper film applying mechanism 910, and the lower film applying mechanism 920 are arranged in the same direction as the return belt 420 and the conveyor belt 410. This arrangement helps to shorten the length of the film applying equipment 10, making the overall structure of the film applying equipment 10 more compact. Of course, this solution is not limited to this. In other embodiments, the conveyor belt 410, the handling component 430, and the return belt 420 can be arranged sequentially along the length of the frame 200.

[0084] Furthermore, the transport assembly 430 includes a first transport structure 431, a second transport structure 433, and an inverting structure 434. The first transport structure 431 transports the product 20 fixture 300 with the first processing stage film application operation to the transfer structure 432. The transfer structure 432 transports the product 20 fixture 300 with the first processing stage film application operation to below the clamping mechanism 800. After the actuating part 132a of the film application mechanism 920 presses the second covering section onto the second curved surface, the transfer structure 432 transports the film-applied product 20 fixture 300 to the second transport structure 433. The second transport structure 433 transports the film-applied product 20 fixture 300 to the inverting structure. The inverting structure 434 inverts the film-applied product 20 fixture 300 to the return flow. This transport assembly 430 is inexpensive, which helps reduce the cost of the film application equipment 10. Of course, this solution is not limited to this. In other embodiments, the transport component 430 can also be a first robot and a second robot. The first robot is used to transport the product 20 fixture 300 with the first processing stage film application operation from the first film application positioning point to below the clamping mechanism 800, that is, to transport the product 20 fixture 300 with the first processing stage film application operation from the first film application positioning point to the second film application positioning point. The second robot is used to transport the product 20 fixture 300 with the film applied to the return belt 420.

[0085] The first conveying structure 431 includes a bracket 431a, a first drive motor 431b, and a clamping member 431c. The clamping member 431c is slidably mounted on the bracket 431a. The first drive motor 431b is mounted on the bracket 431a and is drivenly connected to the clamping member 431c. The clamping member 431c is used to clamp the tooling 300.

[0086] The clamping mechanism 800 includes a fixed plate 810, a second drive motor 820, a connecting plate 830, a third elastic element 840, and a transfer pressure rod 850. The fixed plate 810 is mounted on the frame 200. The second drive motor 820 is mounted on the fixed plate 810 and is drivenly connected to the connecting plate 830. The third elastic element 840 is located in the first direction and acts on the transfer pressure rod 850. The transfer pressure rod 850 is movably mounted on the connecting plate 830. The second drive motor 820 drives the connecting plate 830 to move in the first direction so that the transfer pressure rod 850 presses against the tooling 300, thereby achieving the effect of fixing the tooling 300.

[0087] The first drive motor 431b and the second drive motor 820 are configured as motors or cylinders.

[0088] Furthermore, in this embodiment, multiple transfer pressure rods 850 are provided, and the clamping mechanism 800 is provided with a third elastic element 840 corresponding to each transfer pressure rod 850, which can increase the stability of the clamping mechanism 800 pressing against the tooling 300. Further, in this embodiment, four transfer pressure rods 850 are provided, and the clamping mechanism 800 is provided with a third elastic element 840 corresponding to each transfer pressure rod 850. The transfer pressure rods 850 are distributed at the four corners of the connecting plate 830, thereby pressing against the tooling 300 at the four corners. Of course, this solution is not limited to this. In other embodiments, two transfer pressure rods 850 are provided, and the clamping mechanism 800 is provided with a third elastic element 840 corresponding to each transfer pressure rod 850. The transfer pressure rods 850 are distributed at two opposite corners of the connecting plate 830, thereby pressing against the tooling 300 at two opposite corners.

[0089] The transfer structure 432 includes a single-axis module 432a and a support plate 432b that is drivenly connected to the single-axis module 432a. The support plate 432b is used to support the tooling 300.

[0090] Reference Figure 4 and Figure 6 In this embodiment, the product 20 is an earphone, and the surface to be processed 21 is located on the outer peripheral surface of the earphone's straight stem. However, this solution is not limited to this; in other embodiments, the product 20 can also be a voice recorder, capacitive pen, etc., with a curved surface.
