[0001] This application relates to the field of film removal technology, specifically to a film-tearing device. Background Technology

[0002] In the manufacturing process of electronic devices, a release film is usually applied to the surface of the workpiece to protect it. However, the current process for removing the release film is quite complex. Specifically, workers must first use an identification fixture to obtain information about the workpiece with the release film attached, and then use a specialized film-peeling mechanism to remove it. This process is not only cumbersome but also increases labor intensity, resulting in low efficiency in film removal. Utility Model Content

[0003] In view of the above, it is necessary to provide a film-removing device to improve film removal efficiency.

[0004] This application provides a film-peeling device, including:

[0007] A scanning mechanism, located on the machine base and at the scanning position, is used to acquire information about the workpiece with release film.

[0008] The glue supply mechanism includes a glue supply bracket, a glue supply component, a glue receiving component, a first rolling component, and a second rolling component. The glue supply bracket is disposed on the machine base and located at the film-tearing position. The glue supply component is disposed on the glue supply bracket and is used to provide an adhesive component. The adhesive component is an elastic member with an adhesive surface and a smooth surface arranged opposite to each other. The glue receiving component is disposed on the glue supply bracket. The first rolling component is rotatably connected to the glue supply bracket and is used to roll against the adhesive surface. The second rolling component is rotatably connected to the glue supply bracket and is used to roll against the adhesive surface. The adhesive component is led out from the glue supply component and sequentially abuts against the first rolling component and the second rolling component before being connected to the glue receiving component.

[0009] A pressing mechanism is provided on the adhesive supply bracket and located between the first rolling member and the second rolling member, for pressing the smooth surface so that the adhesive surface adheres to the release film;

[0010] When the adhesive surface is bonded to the release film, the adhesive member is stretched. When the holding mechanism disengages from the adhesive member, the adhesive member causes the bonded release film to detach from the workpiece.

[0011] In some embodiments, the adhesive supply mechanism further includes:

[0012] The first guide member is rotatably connected to the glue supply bracket and disposed between the first rolling member and the glue receiving member, and is used to roll against the smooth surface of the adhesive member.

[0013] In some embodiments, the adhesive supply mechanism further includes:

[0014] The second guide member is rotatably connected to the glue supply bracket and disposed between the second rolling member and the glue receiving member, and is used to roll against the smooth surface of the adhesive member.

[0015] In some embodiments, the holding mechanism includes:

[0016] The pressure-holding drive component is connected to the glue supply bracket;

[0017] A pusher, connected to the pressing drive, presses the smooth surface of the adhesive under the drive of the pressing drive.

[0018] In some embodiments, the number of the pushing members is two, and the two pushing members are spaced apart along the direction from the adhesive supply member to the adhesive receiving member. The film tearing device further includes:

[0019] The tensioning member is rotatably connected to the glue supply bracket and located between the two pushing members, for rolling and abutting the bonding surface of the adhesive member.

[0020] In some embodiments, the turntable includes:

[0021] A rotating component, connected to the rotation drive component, to rotate under the drive of the rotation drive component;

[0022] Multiple positioning components are connected to the rotating component and are spaced apart along the rotation direction of the rotating component.

[0023] In some embodiments, the positioning element includes:

[0024] The main body connects to the rotating component;

[0025] Multiple stops are connected to the main body and spaced apart along the periphery of the main body. The multiple stops and the main body enclose a positioning groove, which is used to accommodate the workpiece.

[0026] In some embodiments, the scanning mechanism includes:

[0027] A scanning bracket is mounted on the machine and located at the scanning position;

[0028] A scanning element, connected to the scanning bracket, is used to acquire information about a workpiece with a release film.

[0029] In some embodiments, the film-tearing device further includes:

[0030] The testing mechanism includes a testing bracket and a testing component. The testing bracket is disposed on the machine base and located between the loading position and the film-tearing position. The testing component is connected to the testing bracket and is used to test the release film on the workpiece.

[0031] In some embodiments, the film-tearing device further includes:

[0032] A protective cover is provided on the machine tool and has a protective space, in which the rotating mechanism, the scanning mechanism, the glue supply mechanism and the pressing mechanism are all housed;

[0033] A warning device is provided on the protective cover and located outside the protective space, and is used to issue a warning message.

[0034] During the operation of the aforementioned film-removing device, the rotating drive unit drives the turntable sequentially through the loading position, scanning position, and film-removing position. The adhesive receiving unit and adhesive supply unit cooperate to move the adhesive component. Specifically, at the loading position, the workpiece with release film is placed on the turntable. At the scanning position, the scanning mechanism acquires information about the workpiece with release film. At the film-removing position, the holding mechanism presses the smooth surface of the adhesive component to adhere the adhesive surface to the release film. At this time, the adhesive component is stretched under the combined action of the first rolling element, the second rolling element, and the holding mechanism. After the holding mechanism holds the pressure for a set time, it detaches from the adhesive component. During this process, the adhesive component resets to drive the release film away from the workpiece. Therefore, the aforementioned film-removing device can continuously realize the transfer of workpieces with release film, information acquisition, and separation of release film and workpiece, simplifying the film removal process, reducing labor intensity, and thus effectively improving film removal efficiency.

[0043] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0044] Please see Figures 1 to 4This application provides a film-peeling device 100, including a machine base 110, a rotating mechanism 120, a scanning mechanism 130, an adhesive supply mechanism 140, and a holding mechanism 150. The rotating mechanism 120 includes a turntable 121 and a rotating drive 122. The turntable 121 carries a workpiece with a release film. The rotating drive 122 is located on the machine base 110 and connected to the turntable 121, driving the turntable 121 to rotate. The machine base 110 has a loading position 110a, a scanning position 110b, and a film-peeling position 110c sequentially along the rotation direction of the turntable 121. The scanning mechanism 130 is located on the machine base 110 and at the scanning position 110b, used to acquire information about the workpiece with the release film. This information can include the workpiece's serial number, dimensions, process nodes, and other processing information during the production process. For example, the rotating drive 122 can be a rotary motor.

[0045] The glue supply mechanism 140 includes a glue supply bracket 141, a glue supply component 142, a glue receiving component 143, a first rolling component 144, and a second rolling component 145. The glue supply bracket 141 is mounted on the machine base 110 and located at the film-tearing position 110c. The glue supply component 142 is mounted on the glue supply bracket 141 and is used to provide the adhesive component 200. The adhesive component 200 is an elastic member and has an adhesive surface 201 and a smooth surface 202 arranged opposite to each other. The glue receiving component 143 is mounted on the glue supply bracket 141. The first rolling component 144 is rotatably connected to the glue supply bracket 141 and is used to roll against the adhesive surface 201. The second rolling component 145 is rotatably connected to the glue supply bracket 141 and is used to roll against the adhesive surface 201. The adhesive component 200 is led out from the glue supply component 142 and sequentially abuts against the first rolling component 144 and the second rolling component 145 before being connected to the glue receiving component 143.

[0046] The holding mechanism 150 is disposed on the adhesive supply bracket 141 and located between the first rolling member 144 and the second rolling member 145. It is used to hold the smooth surface 202 so that the adhesive surface 201 adheres to the release film. When the adhesive surface 201 adheres to the release film, the adhesive member 200 is stretched. When the holding mechanism 150 disengages from the adhesive member 200, the adhesive member 200 causes the adhered release film to detach from the workpiece.

[0047] Please see Figure 2 In this embodiment, the glue supply bracket 141 includes a support frame 1411 and a mounting component 1412. The support frame 1411 is disposed on the machine base 110 and is generally U-shaped. The mounting component 1412 is connected to the support frame 1411 and is located above the turntable 121.

[0048] Please see Figure 2 and Figure 3In this embodiment, the first rolling element 144 includes a plurality of first rollers 1441. Each of the first rollers 1441 is rotatably connected to the glue supply bracket 141 and disposed between the glue supply element 142 and the pressing mechanism 150. The plurality of first rollers 1441 are spaced apart along the direction from the glue supply element 142 to the pressing mechanism 150, and each first roller 1441 is used to roll and abut against the bonding surface 201 (see...). Figure 4 The second rolling element 145 includes a plurality of second rollers 1451, each of which is rotatably connected to the glue supply bracket 141 and disposed between the pressing mechanism 150 and the glue receiving element 143. The plurality of second rollers 1451 are spaced apart along the direction from the pressing mechanism 150 to the glue receiving element 143, and each second roller 1451 is used to roll against the adhesive surface 201 (see...). Figure 4 ).

[0049] In this embodiment, there are three first rollers 1441, which are positioned at different heights on the mounting member 1412. There are two second rollers 1451, also positioned at different heights on the mounting member 1412. The multiple first rollers 1441 and second rollers 1451 at different heights facilitate the guidance of the adhesive member 200 between the glue supply member 142, the holding mechanism 150, and the glue collection member 143. It is understood that in other embodiments, there may be two, four, or more first rollers 1441, and three or more second rollers 1451.

[0050] Please see Figure 2 and Figure 3 In some embodiments, the adhesive supply mechanism 140 further includes a first guide 146, which is rotatably connected to the adhesive supply bracket 141 and disposed between the first rolling member 144 and the adhesive supply member 142, for rolling and abutting against the smooth surface 202 of the adhesive member 200 (see [link]). Figure 4 ).

[0051] Therefore, the direction of the adhesive component 200 flowing from the self-supplying adhesive component 142 to the first roller 1441 can be changed by the first guide component 146, which is beneficial to improving the adjustability of the transmission direction of the adhesive component 200.

[0052] In this embodiment, there are two first guide members 146, which are set at different heights on the mounting member 1412, and a first roller 1441 is provided between the two first guide members 146.

[0053] Please see Figure 2 and Figure 3In some embodiments, the glue supply mechanism 140 further includes a second guide 147, which is rotatably connected to the glue supply bracket 141 and disposed between the second rolling member 145 and the glue receiving member 143, for rolling and abutting the smooth surface 202 of the adhesive member 200.

[0054] Therefore, the direction of the adhesive 200 flowing from the second roller 1451 to the adhesive receiving part 143 can be changed by the second guide 147, which is beneficial to improving the adjustability of the transmission direction of the adhesive 200.

[0055] In this embodiment, there are two second guide members 147, and the two second guide members 147 are set at different heights of the mounting member 1412.

[0056] Please see Figure 2 and Figure 3 In some embodiments, the holding mechanism 150 includes a holding drive 151 and a pusher 152. The holding drive 151 is connected to the adhesive supply bracket 141 and the pusher 152. The holding drive 151 is used to drive the pusher 152 to move downward so that the pusher 152 presses the smooth surface 202 of the adhesive 200.

[0057] In this embodiment, the pressure-holding drive 151 is connected to the mounting component 1412 and is a servo motor.

[0058] Please see Figure 3 and Figure 4 In some embodiments, there are two pushers 152, which are spaced apart along the direction from the glue supply member 142 to the glue collection member 143. The film tearing device 100 also includes a tensioning member 190. The tensioning member 190 is rotatably connected to the glue supply bracket 141 and located between the two pushers 152, and is used to roll against the adhesive surface 201 of the adhesive member 200.

[0059] Therefore, the tension of the adhesive 200 after being pressed by the pusher 152 can be increased by the tension member 190, which is beneficial for the adhesive 200 to drive the release film to detach from the workpiece after the pusher 152 is released.

[0060] Please see Figure 2 In some embodiments, the turntable 121 includes a rotating member 1211 and a plurality of positioning members 1212. The rotating member 1211 is connected to a rotation drive member 122 to rotate under the drive of the rotation drive member 122, and the plurality of positioning members 1212 are all connected to the rotating member 1211 and are spaced apart along the rotation direction of the rotating member 1211.

[0061] Therefore, by using multiple positioning elements 1212, the turntable 121 can synchronously drive multiple workpieces to rotate, thereby improving the efficiency of carrying workpieces.

[0062] In this embodiment, there are four positioning elements 1212. The four positioning elements 1212 are respectively connected to the surface of the rotating element 1211, and the four positioning elements 1212 are equally spaced along the circumference of the rotating element 1211.

[0063] Please see Figure 2 and Figure 5 In some embodiments, the positioning member 1212 includes a main body 1212a and a plurality of stops 1212b. The main body 1212a is connected to the rotating member 1211, and the plurality of stops 1212b are all connected to the main body 1212a and are spaced apart along the periphery of the main body 1212a. The plurality of stops 1212b and the main body 1212a enclose a positioning groove 1212c, which is used to accommodate the workpiece.

[0064] Therefore, the positioning groove 1212c can prevent the workpiece from dislodging from the positioning member 1212 during rotation, thereby improving the stability of the positioning member 1212 in positioning the workpiece. In addition, the positioning groove 1212c has a simple structure and low manufacturing cost, which helps to reduce the cost of positioning the workpiece by the positioning member 1212.

[0065] Please see Figure 2 In some embodiments, the scanning mechanism 130 includes a scanning bracket 131 and a scanning element 132. The scanning bracket 131 is disposed on the machine base 110 and located at the scanning position 110b. The scanning element 132 is connected to the scanning bracket 131 and is used to acquire information about the workpiece with a release film. Exemplarily, the scanning element 132 can be a scanner capable of recognizing barcodes, numerical sequences, and QR codes.

[0066] In this embodiment, the scanning bracket 131 includes a scanning plate 1311 and a scanning rod 1312. The scanning plate 1311 is disposed on the machine base 110 and located at the scanning position 110b. The scanning rod 1312 is connected to the scanning plate 1311 and located above the turntable 121.

[0067] Please see Figure 2 In some embodiments, the film-peeling device 100 further includes a detection mechanism 160. The detection mechanism 160 includes a detection bracket 161 and a detection element 162. The detection bracket 161 is disposed on the machine base 110 and located between the loading position 110a and the film-peeling position 110c. The detection element 162 is connected to the detection bracket 161 and is used to detect the release film on the workpiece to determine whether the release film has been removed from the workpiece. Exemplarily, the detection element 162 can be a detector containing an optical fiber structure.

[0068] In this embodiment, the detection bracket 161 includes a detection plate 1611 and a detection rod 1612. The detection plate 1611 is disposed on the machine base 110, and the detection rod 1612 is connected to the detection plate 1611 and located above the turntable 121.

[0069] Please see Figure 1In some embodiments, the film-tearing device 100 further includes a protective cover 170 and a warning element 180. The protective cover 170 is disposed on the machine base 110 and has a protective space 170a. The rotating mechanism 120, scanning mechanism 130, adhesive supply mechanism 140, and pressing mechanism 150 are all housed within the protective space 170a. The warning element 180 is disposed on the protective cover 170 and located outside the protective space 170a, and is used to issue a warning message. For example, the warning element 180 can be a buzzer or an alarm.

[0070] Therefore, the protective cover 170 can prevent external components from colliding with the rotating mechanism 120, scanning mechanism 130, glue supply mechanism 140 and holding mechanism 150, which helps to improve the safety and service life of the film tearing device 100.

[0071] The operation process of the above-mentioned film-tearing device 100 is roughly as follows:

[0072] First, at the loading position 110a, the workpiece with the release film is placed on the turntable 121;

[0073] Secondly, the rotating drive 122 drives the turntable 121 to move sequentially from the loading position 110a to the scanning position 110b, and the scanning mechanism 130 acquires information about the workpiece with the release film.

[0074] Then, the rotating drive 122 drives the turntable 121 to move from the scanning position 110b to the film tearing position 110c in sequence. The glue receiving part 143 and the glue supply part 142 cooperate to drive the adhesive part 200 to move, so that the adhesive surface 201 of the adhesive part 200 is facing the positioning part 1212.

[0075] Subsequently, the pressing mechanism 150 presses the smooth surface 202 of the adhesive 200 so that the adhesive surface 201 of the adhesive 200 is bonded to the release film. At this time, the adhesive 200 is stretched under the combined action of the first rolling element 144, the second rolling element 145 and the pressing mechanism 150.

[0076] Finally, after the holding mechanism 150 holds pressure for a set time, it disengages from the adhesive component 200. During this process, the adhesive component 200 resets to drive the release film to detach from the workpiece.

[0077] Therefore, the above-mentioned film-removing device 100 can continuously realize the transfer of workpieces with release film, information acquisition, and separation of release film and workpiece, simplifying the film removal process, reducing labor intensity, and thus effectively improving film removal efficiency.
