[0059] The following specific embodiments will further illustrate this application in conjunction with the above-described accompanying drawings. Detailed Implementation

[0060] The following specific embodiments are exemplary and not limiting, and are intended to provide a basic understanding of this application, and are not intended to identify key or decisive elements of this application or limit the scope of protection. As long as there is no structural conflict, the technical features mentioned in the various embodiments can be combined in any manner.

[0061] When a component is considered to be "located" on another component, it can be directly on the other component or may also be interspersed with other components. When a component is considered to be "connected" to another component, it can be directly connected to the other component or may also be interspersed with other components.

[0062] The following describes some embodiments of this application in detail with reference to the accompanying drawings.

[0063] Please see Figures 1 to 4 This application provides a film-removing device 100 for removing protective film from a product. The film-removing device 100 includes a moving component 10, a pressure-holding component 20, and an adsorption component 30. The pressure-holding component 20 connects the moving component 10 and the adsorption component 30. The pressure-holding component 20 includes a first elastic mechanism 21, a second elastic mechanism 22, and a connector 23 connecting the moving component 10, and the adsorption component 30 is connected to the connector 23.

[0064] In some embodiments, the film-peeling device 100 further includes a first pressure sensing element 101 and a second pressure sensing element 102 connected to the connector 23. The moving component 10 is used to drive the first elastic mechanism 21 to press the connector 23 and act on the first pressure sensing element 101. The connector 23 drives the adsorption component 30 to press the protective film on the product. The first pressure sensing element 101 is used to detect the pressure exerted by the adsorption component 30 on the protective film of the product. The moving component 10 is also used to drive the second elastic mechanism 22 to lift the connector 23 and act on the second pressure sensing element 102. The adsorption component 30 is used to adsorb the protective film. The connector 23 drives the adsorption component 30 to rise, and the adsorption component 30 peels the protective film off the product. The second pressure sensing element 102 is used to detect the peeling force when the adsorption component 30 peels off the protective film.

[0065] This application uses the moving component 10 to drive the adsorption component 30 to press the protective film onto the product, thus maintaining pressure. This helps to expel air bubbles between the protective film and the product, ensuring a tight fit between the adsorption component 30 and the protective film. The adsorption component 30 adsorbs the surface of the protective film, providing uniform peeling force and preventing the protective film from tearing or leaving residue due to uneven force during peeling. Furthermore, the first pressure sensor 101 displays the pressure during the pressure maintenance process in real time, and the second pressure sensor 102 displays the peeling force during the peeling process in real time. This allows for timely adjustment of pressure and peeling force based on the peeling situation, improving peeling efficiency and quality, and ultimately increasing production efficiency.

[0066] In some embodiments, the moving component 10 includes a linear module 11, and the pressure holding component 20 is connected to the linear module 11. Optionally, the linear module 11 is driven by a servo motor, which helps to improve the accuracy of control and improve the quality of film tearing.

[0067] In some embodiments, the pressure-holding assembly 20 includes a first connecting plate 24 and a second connecting plate 25 spaced apart along a first direction X. The first connecting plate 24 and the second connecting plate 25 are connected to the linear module 11. A first elastic mechanism 21 is connected to the first connecting plate 24, a second elastic mechanism 22 is connected to the second connecting plate 25, and a connector 23 is slidably connected to the second connecting plate 25. The linear module 11 drives the first connecting plate 24 and the second connecting plate 25 to move simultaneously. When pressure is held, the linear module 11 drives the first connecting plate 24 to move along the first direction X, causing the first elastic mechanism 21 to act on the first pressure sensor 101 and press the connector 23, causing the second elastic mechanism 22 to move away from the second pressure sensor 102. When the film is peeled off, the linear module 11 drives the first connecting plate 24 to move in the opposite direction to the first direction X, causing the second elastic mechanism 22 to act on the second pressure sensor 102 and lift the connector 23, causing the first elastic mechanism 21 to move away from the first pressure sensor 101.

[0068] In some embodiments, the pressure holding assembly 20 includes a third connecting plate 26, which is connected to the linear module 11. The first connecting plate 24 and the second connecting plate 25 are connected to the third connecting plate 26, which is beneficial for the linear module 11 to drive the first connecting plate 24 and the second connecting plate 25 to move simultaneously.

A first adjusting member 213 is connected to the first connecting cover 214 and abuts against the first elastic member 212. One end of a first pad 211 is disposed within the first connecting cover 214 and connected to the first elastic member 212, while the other end extends out of the first connecting cover 214 and passes through the first connecting plate 24 to facilitate contact with the first pressure sensing member 101.

[0073] In some embodiments, the first elastic mechanism 21 includes a second pad 215, a portion of which is disposed within the first elastic member 212, and a first adjusting member 213 is connected to the second pad 215. The second pad 215 facilitates compression of the first elastic member 212 by cooperating with the first pad 211.

[0074] In some embodiments, the outer periphery of the second pad 215 is provided with a second protrusion 215a. Along the first direction X, a portion of the second pad 215 located on one side of the second protrusion 215a is disposed in the cavity of the first elastic member 212. The second pad 215 abuts against the end of the first elastic member 212 away from the first pad 211, so that the second pad 215 can compress the first elastic member 212.

[0075] In some embodiments, the first adjusting member 213 includes an adjusting screw, and by rotating the first adjusting member 213, the length of the first adjusting member 213 extending into the first connecting cover 214 is adjusted to adjust the pre-compression amount of the first elastic member 212.

[0076] Please see Figures 2 to 4 In some embodiments, the second elastic mechanism 22 includes a third pad 221, a second elastic element 222, and a second adjusting element 223, with the second elastic element 222 located between the third pad 221 and the second adjusting element 223. The linear module 11 drives the third pad 221 to act on the second pressure sensing element 102 and compress the second elastic element 222. The second adjusting element 223 moves toward or away from the third pad 221 to adjust the pre-compression of the second elastic element 222. Optionally, the second elastic element 222 includes a spring; alternatively, the second elastic element 222 includes rubber.

[0077] In some embodiments, the second adjusting member 223 moves toward or away from the third pad 221 to adjust the pre-compression amount of the second elastic member 222, which facilitates timely adjustment of pressure according to the film tearing situation and helps to improve the film tearing quality.

[0078] In some embodiments, the second elastic mechanism 22 includes a second connecting cover 224 fixed to the second connecting plate 25, at least a portion of the second elastic member 222 being disposed on the second connecting cover 224, one end of the third pad 221 abutting against the second elastic member 222, and the other end extending out of the second connecting cover 224 to facilitate contact with the second pressure sensing member 102. The second adjusting member 223 abuts against the second elastic member 222 and protrudes from the side of the second connecting plate 25 opposite to the first connecting plate 24.

[0079] In some embodiments, the second adjustment member 223 includes a kimming screw, and by rotating the second adjustment member 223, the distance between the second adjustment member 223 and the third pad 221 is adjusted to adjust the pre-compression amount of the second elastic member 222.

[0080] In some embodiments, the second connecting plate 25 is provided with a through hole 251, a portion of the second elastic member 222 is provided in the through hole 251, and the second adjusting member 223 is connected to the second connecting plate 25 and is at least partially provided in the through hole 251.

[0081] In some embodiments, the connector 23 includes a first mounting plate 231, a guide post 232, and a second mounting plate 233, wherein the first mounting plate 231, the second connecting plate 25, and the second mounting plate 233 are arranged along a first direction X. The guide post 232 passes through the second connecting plate 25 and connects the first mounting plate 231 and the second mounting plate 233. Along the first direction X, a first pressure sensing element 101 and a second pressure sensing element 102 are located on both sides of the first mounting plate 231.

[0082] In some embodiments, the first mounting plate 231 includes a first receiving cavity 231a, the first pressure sensing element 101 is disposed in the first receiving cavity 231a, and the connector 23 includes a first fixing plate 234, which is connected to the first mounting plate 231 and restricts the position of the first pressure sensing element 101.

[0083] In some embodiments, the first fixing plate 234 is provided with a second receiving cavity 234a, and the first pressure sensing element 101 is provided in the first receiving cavity 231a and the second receiving cavity 234a.

[0084] In some embodiments, the first mounting plate 231 includes a third receiving cavity 231b, the second pressure sensing element 102 is disposed in the third receiving cavity 231b, and the connector 23 includes a second fixing plate 235, which is connected to the first mounting plate 231 and restricts the position of the second pressure sensing element 102.

[0085] In some embodiments, the second fixing plate 235 is provided with a fourth receiving cavity 235a, and the second pressure sensing element 102 is provided in the third receiving cavity 231b and the fourth receiving cavity 235a.

[0087] In some embodiments, the adsorption assembly 30 includes an adsorption plate 31, which has adsorption holes 311 that are connected to a pneumatic device and adsorb a protective film through vacuum.

[0088] Please see Figure 5 and Figure 6 When the aforementioned film-peeling device 100 is in use, firstly, during pressure holding, the linear module 11 moves the first connecting plate 24 along the first direction X, causing the first pad 211 to act on the first pressure sensing element 101 and press the first mounting plate 231, thereby moving the second mounting plate 233 along the first direction X and causing the adsorption plate 31 to press against the protective film. After pressure holding is completed, the linear module 11 moves the first connecting plate 24 in the opposite direction to the first direction X, causing the third pad 221 to act on the second pressure sensing element 102 and lift the connecting member 23. The connecting member 23 then moves the adsorption plate 31 to peel the protective film off the product.

[0089] This application uses a linear module 11 to drive an adsorption plate 31 to press the protective film onto the product, maintaining pressure to facilitate the removal of air bubbles between the protective film and the product. This ensures that the adsorption plate 31 and the protective film are in close contact. The adsorption plate 31 adsorbs the surface of the protective film, providing uniform peeling force and preventing the protective film from tearing or leaving residue due to uneven force during film removal. Furthermore, the first pressure sensor 101 displays the pressure during pressure maintenance in real time, and the second pressure sensor 102 displays the peeling force during film removal in real time. This allows for timely adjustment of pressure and peeling force based on the film removal situation, improving film removal efficiency and quality, and thus increasing production efficiency.
