[0010] Alternatively, the second drive member is connected to the sliding connector via a floating joint.

[0011] Alternatively, the pressure holding head is made of aluminum alloy and is coated with silicone.

[0012] Alternatively, the fastener may be equipped with a plurality of the film-applying pressure-holding units.

[0022] Alternatively, the film-applying pressure-holding device may further include:

[0023] The first detection unit is used to detect the position of the protective film and the position of the film to be applied. The first detection unit is electrically connected to the controller.

The film-applying suction head is no longer aligned with the film-applying position, while the pressure-holding head, being spaced apart from the film-applying suction head along the second direction, is aligned with the film-applying position (film application is now complete). Then, the second driving member again drives the sliding connector to slide along the first direction, and the sliding connector drives the pressure-holding head to slide along the first direction, applying pressure along the first direction to the protective film for pressure holding. Therefore, the pressure holding head and the film application suction head can share a set of positioning and driving mechanisms. After the film application suction head completes the film application, the first driving component can immediately drive the pressure holding head to align with the position to be applied and then perform pressure holding. There is no need to transfer the workpiece to be applied, which is highly efficient and has a good pressure holding effect.

[0036] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0037] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0038] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0039] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0041] In the following description, “connection” includes both direct connection between the two and indirect connection between the two through, for example, adapters, middleware, etc.

[0042] In the following description, the protective film and the workpiece to be coated are used only to illustrate the working principle of the coating and pressure holding device, and should not be regarded as part of the coating and pressure holding device.

[0043] In the following description, the driving component can take the form of motor drive, cylinder drive, etc.

[0044] like Figures 1 to 3 As shown, the film-applying and pressure-holding device 100 provided in this application embodiment includes: a fixing member 101, on which a film-applying and pressure-holding unit is mounted; and a first driving member 118, which is used to drive the fixing member 101 to move.

[0045] The film-applying and pressure-holding unit includes: a second driving member 102, which is mounted on the fixing member 101; a sliding connector 103, which is slidably engaged with the fixing member 101 along a first direction, and the second driving member 102 is used to drive the sliding connector 103 to slide; a pressure-holding head 105 and a film-applying suction head 106, which are connected to the sliding connector 103 and spaced apart along a second direction; the second direction intersects the first direction.

[0046] Specifically, the function of the film-applying and pressure-holding unit is to pick up the protective film, attach the protective film to the workpiece to be coated, and apply pressure to the protective film for pressure holding. The fixing member 101 is not absolutely stationary, but rather relative to the sliding connector 103. The fixing member 101 is defined as a relatively fixed structural component. In actual operation, the first driving member 118 can use a robotic arm to drive the fixing member 101 to move, and the fixing member 101 will correspondingly drive the film-applying and pressure-holding unit to move. The robotic arm can have three-dimensional spatial motion freedom. The first driving member 118 can also include, as described below, a fourth driving member 119, a fifth driving member 120, and a sixth driving member 134, which drive the fixing member 101 to move. The first driving member 118 can drive the fixing member 101 to move or rotate in one direction, two directions, or three directions, with the aim of moving the film-applying and pressure-holding unit to the desired working position.

[0047] like Figure 1 and Figure 2As shown, in one embodiment of this application, the second driving member 102 in the film-applying pressure-holding unit is mounted on the adapter 1011, and the adapter 1011 is then fixedly connected to the fixing member 101. The adapter 1011 is considered part of the fixing member 101, and therefore is still considered as the second driving member 102 mounted on the fixing member 101. In other embodiments of this application, the fixing member 101 may be an L-shaped plate. In one embodiment of this application, the fixing member 101 is equipped with a first slide rail 107 extending along a first direction, and the sliding connector 103 is equipped with a slider. The sliding connection between the sliding connector 103 and the fixing member 101 along the first direction is achieved through the cooperation of the first slide rail 107 and the slider. In other embodiments of this application, the fixing member 101 is equipped with a slider, and the sliding connector 103 is equipped with a first slide rail 107 extending along a first direction. The sliding connection between the sliding connector 103 and the fixing member 101 along the first direction is achieved through the cooperation of the first slide rail 107 and the slider. Taking the second driving component 102 as an example, which uses a cylinder, the moving end of the cylinder is connected to the sliding connector 103. The extension and retraction of the cylinder piston rod can drive the sliding connector 103 to slide relative to the fixed component 101 in the first direction. The second driving component 102 can also use a motor screw mechanism or other similar means to drive the sliding connector 103 to slide in the first direction.

[0048] The film-applying suction head 106 is used to pick up the protective film, and the pressure-holding head 105 is used to apply pressure to the protective film attached to the workpiece to ensure the flatness of the bonding surface and the completeness of the application. Therefore, in this embodiment, film application and pressure holding are two different structures. In this embodiment, the pressure-holding head 105 and the film-applying suction head 106 are indirectly connected to the sliding connector 103 through the film-applying connector 104. In other embodiments of this application, the pressure-holding head and the film-applying suction head 106 can also be directly connected to the sliding connector 103. The pressure-holding head 105 and the film-applying suction head 106 are spaced apart along a second direction. The second direction and the first direction are two directions that intersect in space.

[0049] During operation, the film application nozzle 106 picks up the protective film, aligns it with the desired film application position on the workpiece, and then the second drive member 102 drives the sliding connector 103 to slide along the first direction. The sliding connector 103 drives the film application nozzle 106 to slide along the first direction, attaching the protective film to the desired film application position on the workpiece. Then, the second drive member 102 drives the sliding connector 103 to return along the first direction, and the first drive member 118 drives the fixing member 101 to move. The fixing member 101 drives the sliding connector 103, the pressure head 105, and the film application nozzle 106 to move. The film application nozzle 106 is no longer aligned with the desired film application position, while the pressure head 105, being spaced apart from the film application nozzle 106 along the second direction, is aligned with the desired film application position (the film application is now complete). Then, the second driving member 102 drives the sliding connector 103 to slide along the first direction again. The sliding connector 103 drives the pressure holding head 105 to slide along the first direction, applying pressure along the first direction to the protective film for pressure holding.

[0050] As can be seen from the above description, since the pressure holding head 105 and the film application suction head 106 are spaced apart on the sliding connector 103 along the second direction, they can share a set of positioning and driving mechanisms. After the film application suction head 106 completes the film application, the first driving member 118 can immediately drive the pressure holding head 105 to align with the position to be applied and then perform pressure holding. There is no need to transfer the workpiece to be applied, which is highly efficient and has a good pressure holding effect.

[0051] like Figure 1 and Figure 2 As shown, in one embodiment of this application, the film-applying pressure-holding unit further includes a film-applying connector 104. The film-applying connector 104 and the sliding connector 103 are slidably engaged along the first direction, and the pressure-holding head 105 and the film-applying suction head 106 are connected to the film-applying connector 104.

[0052] Specifically, in one embodiment of this application, a second slide rail 108 extending along a first direction is mounted on the sliding connector 103, and a slider is mounted on the film-applying connector 104, with the slider slidingly engaged with the second slide rail 108. In another embodiment of this application, a slider is mounted on the sliding connector 103, and a second slide rail 108 extending along a first direction is mounted on the film-applying connector 104, with the slider slidingly engaged with the second slide rail 108. The pressure-holding head 105 and the film-applying suction head 106 are first mounted on the adapter block 109, and the adapter block 109 is then connected to the film-applying connector 104. The adapter block 109 can be considered as part of the film-applying connector 104; therefore, the pressure-holding head 105 and the film-applying suction head 106 are indirectly connected to the film-applying connector 104. In other embodiments of this application, the pressure-holding head 105 and the film-applying suction head 106 can also be directly connected to the film-applying connector 104.

[0053] During operation, when the second driving member 102 drives the sliding connector 103 to move along the first direction, after the film-applying suction head 106 or the pressure-holding head 105 comes into contact with the film-applying workpiece, the film-applying connector 104 can slide relative to the sliding connector 103 along the first direction, thereby providing a buffer for the film-applying suction head 106 or the pressure-holding head 105 and preventing the film-applying suction head 106 or the pressure-holding head 105 from being damaged due to excessive pressure.

[0054] In one embodiment of this application, the film applicator 106 and the pressure holding head 105 can be connected to the film applicator 104 or the sliding connector 103 via a quick-release structure, thereby allowing different film applicators 106 and pressure holding heads 105 to be replaced according to different workpiece types or sizes.

[0055] like Figure 1 and Figure 2 As shown in the embodiment of this application, the film-applying pressure-holding unit further includes a suction nozzle adjustment member 110. The suction nozzle adjustment member 110 is equipped with a suction nozzle 111, and the suction nozzle adjustment member 110 is connected to the film-applying connector 104. The suction nozzle adjustment member 110 can adjust the relative position of the suction nozzle 111 and the film-applying suction head 106 in the first direction.

[0056] Specifically, the protective film has two layers on each side: a large base film on one side and a smaller film of similar size on the other. Each smaller film has a handle. After removing the base film, the protective film with the smaller film attached is applied to the workpiece to be covered. Finally, the smaller film is peeled off by holding the handle, leaving the protective film already applied to the workpiece. The suction nozzle 111 is used to pick up the handles of the smaller films on the protective film and works in conjunction with the film application suction head 106. In one embodiment of this application, the suction nozzle adjusting member 110 can have different through holes along the first direction. After inserting a pin into different through holes, it connects to the film application connector 104, thereby adjusting the relative position of the suction nozzle 111 and the film application suction head 106 in the first direction, thus accommodating more shapes of protective films. In other embodiments of this application, the suction nozzle adjusting member 110 can be threadedly connected to the film application connector 104 via a screw. Rotating the screw can adjust the relative position of the suction nozzle 111 and the film application suction head 106 in the first direction. The nozzle adjustment component 110 can be directly or indirectly connected to the film attaching component 104.

[0057] like Figure 2 As shown in the embodiment of this application, the film-applying pressure-holding unit further includes a spring adjusting block 112, which is fixedly connected to the sliding connector 103. A first elastic element 114 is provided between the spring adjusting block 112 and the limiting post 113. The limiting post 113 can abut against the film-applying connector 104 to apply pressure along the first direction to the pressure-holding head 105.

[0058] Specifically, after the spring adjusting block 112 is fixedly connected to the sliding connector 103, it can apply pressure in the first direction to the film-applying connector 104 through the first elastic element 114 and the limiting post 113, thus applying pressure in the first direction to the pressure-holding head 105. The spring adjusting block 112 can adjust the preload of the first elastic element 114 by adjusting the length of the screw mounted on it, or by slidingly engaging with the limiting post 113 and adjusting the nut on the limiting post 113 to adjust the preload of the first elastic element 114. The first elastic element 114 presses against the limiting post 113, and the limiting post 113 then directly or indirectly abuts against the film-applying connector 104, thereby applying pressure in the first direction to the pressure-holding head 105 and the film-applying suction head 106.

[0059] When the pressure-holding head 105 needs to apply pressure to the protective film during operation, the second driving member 102 drives the sliding connector 103 to slide along the first direction. After the pressure-holding head 105 contacts the protective film attached to the workpiece to be covered, as the sliding connector 103 continues to slide, the film-applying connector 104 overcomes the elastic force of the first elastic member 114 and slides relative to the sliding connector 103. The pressure-holding head 105 is buffered, thus avoiding damage to the workpiece to be covered while providing pressure.

[0060] like Figure 2 As shown in the embodiment of this application, the film-applying pressure-holding unit further includes a sensor mounting block 115, on which a pressure sensor 116 is mounted. The sensor mounting block 115 is fixedly connected to the film-applying connector 104, and the limiting post 113 can abut against the pressure sensor 116. The pressure sensor 116 is electrically connected to the second driving member 102.

[0061] Specifically, the sensor mounting block 115 is fixedly connected to the film-applying connector 104, and the pressure sensor 116 is mounted on the sensor mounting block 115. Therefore, after the limiting post 113 abuts against the pressure sensor 116, it is equivalent to indirectly abutting against the film-applying connector 104. During the pressure-holding head 105 pressurizes the protective film, as the second driving member 102 drives the sliding connector 103 to slide along the first direction, the film-applying connector 104 slides relative to the sliding connector 103 along the first direction, and the first elastic member 114 is further compressed. The pressure sensor 116 can detect the magnitude of the pressure applied to the first elastic member 114. When the pressure reaches the pressurization value, the pressure sensor 116 transmits an electrical signal to the second driving member 102, and the second driving member 102 stops driving, maintaining the pressure of the pressurization head 105 to ensure consistent pressurization of the protective film.

[0062] like Figure 1 and Figure 2As shown, in an embodiment of this application, the second driving member 102 is connected to the sliding connector 103 via a floating joint 117.

[0063] Specifically, the second driving member 102 and the sliding connector 103 are connected by a floating joint 117, which can compensate for the installation error of the second driving member 102 or the error caused by vibration during the driving process, ensure the smooth movement of the sliding connector 103, further ensure the smooth process of the film-applying suction head 106 picking up and applying the protective film, and ensure the stable pressure holding of the pressure holding head 105.

[0064] In the embodiments of this application, the pressure holding head 105 is made of aluminum alloy and is covered with silicone.

[0065] Specifically, the pressure-holding head 105, made of aluminum alloy, ensures dimensional accuracy, and the silicone coating ensures that the protective film will not be damaged during the pressure-holding process.

[0066] like Figure 1 and Figure 2 As shown in the embodiments of this application, the fastener 101 is equipped with a plurality of film-applying pressure-holding units.

[0067] Specifically, the fixing member 101 is equipped with multiple (i.e., at least two) film-applying and pressure-holding units. The film-applying suction head 106 and the pressure-holding head 105 in each film-applying and pressure-holding unit can be driven independently, which can improve and ensure the film-applying accuracy when multiple workpieces need to be film-applied. Furthermore, by adjusting the spring adjusting block 112, the pressure-holding consistency of multiple film-applying and pressure-holding units can also be ensured.

[0068] like Figure 3 As shown in the embodiments of this application, the film-applying and pressure-holding device 100 further includes: a film-applying platform 122, wherein the film-applying platform 122 is provided with a plurality of workpiece clamping units 123 to be applied with film; the film-applying and pressure-holding units correspond one-to-one with the workpiece clamping units 123 to be applied with film.

[0069] Specifically, the number of multiple (i.e., at least two) workpiece clamping units 123 on the film application platform 122 can be the same as the number of film application and pressure holding units. For example, in... Figure 1 and Figure 3In the illustrated embodiment, there are four film-applying pressure-holding units and four workpiece clamping units 123, the specific number of which can be increased or decreased as needed. Each film-applying pressure-holding unit corresponds one-to-one with each workpiece clamping unit 123, meaning that the film-applying suction head 106 of one film-applying pressure-holding unit can apply film to a workpiece clamped on one workpiece clamped on one workpiece clamping unit 123, and the pressure-holding head 105 of the film-applying pressure-holding unit can maintain pressure on the protective film applied to the workpiece clamped on one ...

[0070] like Figure 4 and Figure 5 As shown in this embodiment, the film-applying platform 122 is equipped with an adjustment platform 124, and the adjustment platform 124 is equipped with an adsorption platform 125. The workpiece clamping unit 123 includes: an adsorption hole 126 and a positioning unit 127 disposed on the adsorption platform 125; a positioning fixing plate 128 slidably engaged with the adjustment platform 124; a push block 132 slidably engaged with the positioning fixing plate 128; a spring fixing plate 130 fixedly connected to the positioning fixing plate 128; and a second elastic member 131 disposed between the push block 132 and the spring fixing plate 130. The film-applying platform 122 is also equipped with a third driving member, which is used to drive the positioning fixing plate 128 closer to or further away from the adsorption platform 125.

[0071] Specifically, the adjustment platform 124 is mounted on the film-applying platform 122. Its levelness can be adjusted using wedges, set screws, etc., or it can be fixed to the film-applying platform 122 to support the adsorption platform 125, the workpiece clamping unit 123, etc. The adsorption platform 125 is mounted on the adjustment platform 124 and connected to an external negative pressure mechanism (not shown in the figure). When the negative pressure mechanism operates, negative pressure is generated at the adsorption holes 126 on the adsorption platform 125 to adsorb the workpiece to be applied. A positioning unit 127 is also provided on the adsorption platform 125. The positioning unit 127 can be a positioning pin, positioning block, or other structure, arranged around the adsorption holes 126, and used to position the workpiece to be applied. The positioning fixing plate 128 slides along the second direction with the adjustment platform 124 via a third slide rail 129. The push block 132 slides along the second direction with the positioning fixing plate 128. A second elastic element 131 is provided between the push block 132 and the spring fixing plate 130. The film application platform 122 is also equipped with a third driving component (not shown in the figure), which can drive the positioning and fixing plate 128 to move closer to or away from the adsorption platform 125 in the second direction.

[0072] The working process of the workpiece clamping unit 123 to be coated is as follows:

[0073] After the workpiece to be coated is placed on the adjustment platform 124, the positioning unit 127 positions the workpiece. The third driving member drives the positioning fixing plate 128 to approach the adsorption platform 125 along the second direction. The push block 132 thus pushes the workpiece to be coated along the second direction. During this process, the second elastic member 131 provides cushioning for the push block 132. Finally, the workpiece to be coated is clamped by the push block 132 and the positioning unit 127, and the adsorption hole 126 adsorbs the workpiece to be coated.

[0074] like Figures 1 to 3 As shown, the film-applying and pressure-holding device 100 of this application embodiment further includes a first detection unit 121. The first detection unit 121 is used to detect the position of the protective film and the position of the film to be applied. The first detection unit 121 is electrically connected to a controller. The controller controls the first driving member 118 to drive the fixing member 101 to move, so that the film-applying suction head 106 reaches the position of the protective film or the position of the film to be applied; the first direction, the second direction and the third direction intersect each other.

[0075] Specifically, the first detection unit 121 can employ a CCD (Charge Coupled Device) camera, laser sensor, etc., to detect the position of the protective film and the position of the film to be applied. The first detection unit 121 transmits the protective film position signal and the film-to-be-applied position signal to the controller. The controller drives the first driving component 118 based on these signals. The first driving component 118 then drives the fixing component 101 to move based on these signals, enabling the film-applying suction head 106 to accurately reach the protective film position, pick up the protective film, and then reach the film-to-be-applied position to apply the protective film to the workpiece. Alternatively, it can bring the pressure-holding head 105 to the film-to-be-applied position, and then the second driving component 102 drives the pressure-holding head 105 to maintain pressure. The entire process of protective film pickup, application, and pressure holding is accurate. Using a controller to control the movement of the driving component to reach the target position is existing technology and will not be described in detail here.

[0076] like Figure 3 As shown, in one embodiment of this application, the first driving member 118 includes a fourth driving member 119, a fifth driving member 120, and a sixth driving member 134. The sixth driving member 134 is used to drive the fourth driving member 119 to move along the second direction, the fourth driving member 119 is used to drive the fifth driving member 120 to move along a third direction, and the fifth driving member 120 is used to drive the fixing member 101 to move along the first direction; the first direction, the second direction, and the third direction intersect each other.

[0077] Specifically, in this embodiment, the fourth driving member 119, the fifth driving member 120, and the sixth driving member 134 can be three independent cylinders. The moving end of the fourth driving member 119 is connected to the moving end of the sixth driving member 134, the moving end of the fifth driving member 120 is connected to the moving end of the fourth driving member 119, and the moving end of the fifth driving member 120 is connected to the fixing member 101. At this time, the actions of the fourth driving member 119, the fifth driving member 120, and the sixth driving member 134 can realize the three-way translational drive of the first driving member 118. As mentioned above, in other embodiments of this application, the first driving member 118 can also be a robotic arm.

[0078] like Figure 3 As shown in the embodiments of this application, the film-applying pressure-holding device further includes a second detection unit 133. The second detection unit 133 is used to detect whether the protective film adsorbed by the film-applying suction head 106 is offset. When the second detection unit 133 detects that the protective film is offset, the film-applying suction head 106 disconnects from adsorbing the protective film.

[0079] Specifically, the second detection unit 133 can employ a CCD (Charge Coupled Device) camera, laser sensor, etc., and is positioned on the film application platform 122, or on the ground or elsewhere below the film application nozzle in the first direction, to detect whether the protective film adsorbed by the film application nozzle 106 has shifted. After the film application nozzle 106 adsorbs and applies the film, the movement path of each film application nozzle 106 passes above the second detection unit 133. When the second detection unit 133 detects that the protective film adsorbed by the film application nozzle 106 has shifted, it can send an electrical signal to the film application pressure holding unit. Upon receiving the electrical signal, the film application pressure holding unit moves to the film discarding position, the film application nozzle 106 disconnects from adsorption, and the protective film is discarded, thereby preventing incorrect placement of the protective film on the workpiece to be applied. The disconnected film application nozzle 106 can return to the position where it adsorbed the protective film and adsorb new protective film for application.

[0080] The detection unit sends signals to the negative pressure mechanism to control its on / off state, which is existing technology and will not be described in detail here.

[0081] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims.
