Description

Technical Field

[0001] This utility model belongs to the field of product feeding technology, and more specifically, it relates to a feeding component and mechanism. Background Technology

[0002] After processing high-precision products such as glass lenses or wafers, these products need to be coated before being cut to prevent them from being scratched during the cutting process. However, the current equipment used for coating and cutting products is quite complex. Utility Model Content

[0003] The present invention provides a feeding component that can perform film-coating feeding of products and has a simple structure.

[0004] The technical solution adopted in this utility model is a feeding assembly, including:

[0005] Support platform;

[0006] A first unwinding structure and a second unwinding structure are provided. The first unwinding structure is disposed at one end near the support platform. The first unwinding structure is used to unwind a first protective film. The first protective film is close to the support platform to support the product. The second unwinding structure is used to unwind a second protective film, and the second protective film is located above the first protective film.

[0007] A roll forming structure is disposed at the end of the support platform away from the first unwinding structure. The roll forming structure is provided with a first roll forming channel. The first protective film and the second protective film are located within the first roll forming channel and can be roll-formed to fit together and can move in a direction away from the first unwinding structure.

[0008] A film-cutting structure is disposed at one end of the first roller pressing channel away from the first unwinding structure, and is used to cut the first protective film and the second protective film that flow out of the first roller pressing channel and are bonded together.

[0009] In the feeding assembly of this application, a first unwinding structure is provided at one end near the support platform, and the first protective film unwound by the first unwinding structure can be close to the support platform. When the product is placed on the first protective film, the support platform can support the product. In addition, a second unwinding structure is provided, and the second protective film unwound by the second unwinding structure is located above the first protective film. The first and second protective films are rolled through a first rolling channel provided in the rolling structure, which can make the first and second protective films adhere to each other to coat the product. At the same time, during the rolling process, the product coated with the first and second protective films can flow out of the first rolling channel under the action of the friction of the rolling. The film cutting structure provided at the end of the first rolling channel away from the first unwinding structure can cut the first and second protective films on the product that flow out of the first rolling channel, separating the first protective film on the product from the first protective film in the first rolling channel, and separating the second protective film on the product from the second protective film in the first rolling channel.

[0010] This method enables the product to be coated and cut, and the first roller pressing channel can be used to achieve mutual bonding of the first protective film and the second protective film, thereby coating the first protective film and the second protective film onto the product respectively. Furthermore, the friction force during roller pressing can be used to drive the first protective film and the second protective film to move, thereby unwinding the first protective film on the first unwinding structure and the second protective film on the second unwinding structure, making the structure of the cutting component simpler and the cost lower.

[0011] Furthermore, the second unwinding structure is positioned higher than the first unwinding structure.

[0012] Furthermore, the second unwinding structure is positioned close to the roll forming structure.

[0013] Furthermore, the first unwinding structure includes a first unwinding shaft and a first reversing roller. The first unwinding shaft is disposed on one end side of the support platform. The first unwinding shaft is used to install a first protective film in the form of a roll. The first reversing roller is disposed on the end side of the first unwinding shaft. The first reversing roller is used to contact the first protective film and cooperate with the first roller pressing channel so that the first protective film can be close to the support platform.

[0014] The second unwinding structure includes a second unwinding shaft and a second reversing roller. The second unwinding shaft is disposed above the roll pressing structure. A second protective film in the form of a roll is mounted on the second unwinding shaft. The second reversing roller is disposed at one end of the first roll pressing channel away from the shearing structure and is used to contact the second protective film so that the second protective film can enter the first roll pressing channel.

[0015] Furthermore, the roll forming structure is provided with multiple sets of the first roll forming channels, which are spaced apart between the first unwinding structure and the film cutting structure.

[0016] Furthermore, the roll forming structure is also provided with a second roll forming channel, which is located on the side of the first roll forming channel away from the first unwinding structure, and the first protective film and the second protective film flowing out from the first roll forming channel can enter the second roll forming channel;

[0017] The shearing structure is disposed between the first roller pressing channel and the second roller pressing channel.

[0018] Furthermore, the roll forming structure includes a first pressure roller and a second pressure roller, which are rotatably disposed at one end of the support platform away from the first unwinding structure. The first pressure roller and the second pressure roller rotate in opposite directions. The first pressure roller and the second pressure roller are arranged opposite to each other to form the first roll forming channel. The first protective film and the second protective film in the first roll forming channel are rolled together by the action of the first pressure roller and the second pressure roller until they are pressed together. The first protective film and the second protective film that are pressed together can move in a direction away from the first unwinding structure. The first pressure roller and the second pressure roller are rubber rollers.

[0019] The roll forming structure further includes a third pressure roller and a fourth pressure roller. The third pressure roller and the fourth pressure roller are rotatably disposed at one end of the first roll forming channel away from the first unwinding structure. The rotation directions of the third pressure roller and the fourth pressure roller are opposite. The third pressure roller and the fourth pressure roller are arranged opposite to each other to form the second roll forming channel. The third pressure roller and the fourth pressure roller are rubber rollers.

[0020] Furthermore, it also includes a feeding structure, which includes a feeding plate, one end of which is connected to the first roller pressing channel, and the other end of which gradually slopes downward.

[0021] A stop is provided at the end of the feeding plate away from the first roller pressing channel.

[0022] Furthermore, it also includes a feeding structure, which includes a feeding plate, one end of which is connected to the second roller pressing channel, and the other end of which gradually slopes downward.

[0023] A stop is provided at the end of the feeding plate away from the second roller pressing channel.

[0024] Furthermore, the feeding structure also includes a first transfer drive and an adsorption component.

Therefore, they should not be construed as limitations on this utility model.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0046] This application provides a feeding assembly for feeding products after coating, and the feeding assembly has a simple structure. The product can be a glass lens or a wafer, etc.

[0047] Combination Figure 1 , Figure 2 and Figure 3 A feeding assembly includes a support platform 100, a first unwinding structure 200, a second unwinding structure 300, a roller pressing structure 400, and a film cutting structure 500.

[0048] The first unwinding structure 200 is located at one end near the support platform 100. The first unwinding structure 200 is used to unwind the first protective film 210, and the first protective film 210 can be close to the support platform 100 to support the product 700. It can be understood that when the product 700 is placed on the first protective film 210, the support platform 100 can support the product 700 through the first protective film 210, and can maintain support for the product 700 when the first protective film 210 moves the product 700.

[0049] The second unwinding structure 300 is used to unwind the second protective film 310, and the second protective film 310 and the first protective film 210 are located above the first protective film 210. It can be understood that when the second protective film 310 unwound by the second unwinding structure 300 is located above the first protective film 210, the second protective film 310 can be easily attached to the first protective film 210, thereby achieving film wrapping of the product 700.

[0050] The roller pressing structure 400 is disposed at one end of the support platform 100 away from the first unwinding structure 200. The roller pressing structure 400 is provided with a first roller pressing channel 410. The first protective film 210 and the second protective film 310 are located in the first roller pressing channel 410 and can be roller pressed to fit together and can move in a direction away from the first unwinding structure 200.

[0051] Specifically, the first protective film 210 and the second protective film 310 can be rolled in the first roller pressing channel 410 and can be bonded together during the rolling process in the first roller pressing channel 410, thereby achieving the coating of the product 700 on the first protective film 210. In addition, the first protective film 210 and the second protective film 310 can move under the action of friction during the rolling process. During the movement of the first protective film 210, the first unwinding structure 200 can unwind, and during the movement of the second protective film 310, the second unwinding structure 300 can unwind.

[0052] The film-cutting structure 500 is located at one end of the first roller pressing channel 410 away from the first unwinding structure 200, and is used to cut the first protective film 210 and the second protective film 310 that flow out of the first roller pressing channel 410 and are bonded together. It can be understood that since the first protective film 210 and the second protective film 310 are bonded together under the action of the first roller pressing channel 410, the film-cutting structure 500 can cut the first protective film 210 and the second protective film 310 simultaneously when cutting the film.

[0053] In the unloading assembly of this application, a first unwinding structure 200 is provided at one end near the support table 100, and the first protective film 210 unwound by the first unwinding structure 200 can be close to the support table 100. When the product 700 is placed on the first protective film 210, the support table 100 can support the product 700. In addition, a second unwinding structure 300 is provided, and the second protective film 310 unwound by the second unwinding structure 300 is located above the first protective film 210. The first protective film 210 and the second protective film 310 are rolled together by the first rolling channel 410 provided in the rolling structure 400, so that the first protective film 210 and the second protective film 310 can adhere to each other and support the product 700. During the coating process, the product 700 coated with the first protective film 210 and the second protective film 310 flows out of the first roller pressing channel 410 under the action of the friction of the roller pressing. The film cutting structure 500 located at the end of the first roller pressing channel 410 away from the first unwinding structure 200 can cut the first protective film 210 and the second protective film 310 on the product 700 that flow out of the first roller pressing channel 410, so that the first protective film 210 on the product 700 is separated from the first protective film 210 in the first roller pressing channel 410, and the second protective film 310 on the product 700 is separated from the second protective film 310 in the first roller pressing channel 410.

[0054] This method enables the film coating and unloading of product 700. The first roller pressing channel 410 can be used to bond the first protective film 210 and the second protective film 310 together, thereby coating the first protective film 210 and the second protective film 310 onto product 700 respectively. Furthermore, the friction force during roller pressing can be used to move the first protective film 210 and the second protective film 310, thereby unwinding the first protective film 210 on the first unwinding structure 200 and the second protective film 310 on the second unwinding structure 300. This makes the structure of the unloading assembly simpler and the cost lower.

[0055] Combination Figure 1 , Figure 2 and Figure 3 In one embodiment, in order to facilitate the second protective film 310 unwound by the first unwinding structure 200 to be located above the first protective film 210, so that the second protective film 310 can be rolled onto the first protective film 210 in the first rolling channel 410, the second unwinding structure 300 may be set higher than the first unwinding structure 200.

[0056] Furthermore, in one embodiment, the second unwinding structure 300 may be disposed close to the rolling structure 400. It is understood that when the second unwinding structure 300 is disposed close to the rolling structure 400, the portion of the first protective film 210 unwound by the first unwinding structure 200 that is far from the rolling structure 400 can be prevented from being blocked by the second protective film 310 unwound by the second unwinding structure 300, thereby facilitating the placement of the product 700 on the first protective film 210.

[0057] For example, the second unwinding structure 300 can be disposed above the rolling structure 400, so that part of the first protective film 210 between the first unwinding structure 200 and the rolling structure 400 can be prevented from being blocked by the second protective film 310, making it convenient to place the product 700 on the first protective film 210.

[0058] Combination Figure 1 , Figure 2 and Figure 3 The first unwinding structure 200 may include a first unwinding shaft 220 and a first reversing roller 230. The first unwinding shaft 220 is disposed on one end of the support platform 100 and is used to mount a first protective film 210 in the form of a roll. The first reversing roller 230 is disposed on one side of the first unwinding shaft 220 and is used to contact the first protective film 210 and cooperate with the first roller pressing channel 410 so that the first protective film 210 can be close to the support platform 100.

[0059] Specifically, the first protective film 210 unwound on the first unwinding shaft 220 contacts the first reversing roller 230 and changes its movement path under the action of the first reversing roller 230. It also cooperates with the first roller pressing channel 410 to make the first protective film 210 close to the support platform 100, so that the support platform 100 can support the product 700 through the first protective film 210.

[0060] See Figure 1 In one embodiment, the second unwinding structure 300 may include a second unwinding shaft 320 and a second reversing roller 330. The second unwinding shaft 320 is disposed above the roll forming structure 400, and a second protective film 310 in the form of a roll is mounted on the second unwinding shaft 320. The second reversing roller 330 is disposed at one end of the first roll forming channel 410 away from the shearing structure 500, and is used to contact the second protective film 310 so that the second protective film 310 can enter the first roll forming channel 410.

[0061] It is understood that by placing the second unwinding shaft 320 above the roller pressing structure 400, the second protective film 310 unwound by the second unwinding structure 300 can be prevented from obscuring the first protective film 210 on the support platform 100. At the same time, the movement direction of the second protective film 310 can be changed by the second reversing roller 330, so that the second protective film 310 can enter the first roller pressing channel 410. This method can both prevent the second protective film 310 located above the first protective film 210 from obscuring the first protective film 210 and allow the second protective film 310 to enter the first roller pressing channel 410.

[0062] See Figure 1 In one embodiment, the roll forming structure 400 may be provided with multiple sets of first roll forming channels 410, which are spaced apart between the first unwinding structure 200 and the film cutting structure 500.

[0063] Understandably, since the first protective film 210 and the second protective film 310 need to move and be rolled together by the action of the first roller pressing channel 410, multiple first roller pressing channels 410 are arranged at intervals before the first unwinding structure 200 and the film cutting structure 500. This allows the first protective film 210 and the second protective film 310 to enter each first roller pressing channel 410 in sequence, thereby improving the bonding effect of the first protective film 210 and the second protective film 310 and improving the stability of the movement of the first protective film 210 and the second protective film 310. It also enables the bonded first protective film 210 and the second protective film 310 to move a longer distance.

[0064] Combination Figure 1 , Figure 2 and Figure 3 In one embodiment, to facilitate the cutting structure 500 in cutting the first protective film 210 and the second protective film 310 flowing out of the first roller pressing channel 410 onto the product 700, separating the first protective film 210 on the product 700 from the first protective film 210 in the first roller pressing channel 410, and separating the second protective film 310 on the product 700 from the second protective film 310 in the first roller pressing channel 410, the roller pressing structure 400 is further provided with a second roller pressing channel 420. The second roller pressing channel 420 is located on the side of the first roller pressing channel 410 away from the first unwinding structure 200, and the first protective film 210 and the second protective film 310 flowing out of the first roller pressing channel 410 can enter the second roller pressing channel 420. The cutting structure 500 is disposed between the first roller pressing channel 410 and the second roller pressing channel 420.

[0065] It is understood that when the film cutting structure 500 located between the first roller pressing channel 410 and the second roller pressing channel 420 cuts the first protective film 210 and the second protective film 310, the first roller pressing channel 410 and the second roller pressing channel 420 can fix the two ends of the first protective film 210 and the two ends of the second protective film 310, thereby facilitating the film cutting structure 500 to cut the first protective film 210 and the second protective film 310.

[0066] In one embodiment, the film-cutting structure 500 may include a blade 510 and a film-cutting drive 520. The blade 510 is disposed between the first roller pressing channel 410 and the second roller pressing channel 420. The film-cutting drive 520 is driven to connect with the blade 510 to drive the blade 510 to move in a direction perpendicular to the moving direction of the first protective film 210 and the second protective film 310, thereby cutting the first protective film 210 and the second protective film 310 between the first roller pressing channel 410 and the second roller pressing channel 420.

[0067] For example, the film cutting drive 520 can be disposed on the support platform 100. The film cutting drive 520 can be a transmission belt that moves in a direction perpendicular to the moving direction of the first protective film 210 and the second protective film 310. The blade 510 is disposed on the transmission belt, thereby driving the blade 510 to move.

[0068] See Figure 1 and Figure 3 The roll forming structure 400 may include a first pressure roller 430 and a second pressure roller 440. The first pressure roller 430 and the second pressure roller 440 are respectively rotatably disposed at one end of the support platform 100 away from the first unwinding structure 200. The first pressure roller 430 and the second pressure roller 440 rotate in opposite directions. The first pressure roller 430 and the second pressure roller 440 are arranged opposite to each other and form a first roll forming channel 410. The first protective film 210 and the second protective film 310 in the first roll forming channel 410 are rolled together by the action of the first pressure roller 430 and the second pressure roller 440 until they are pressed together. The first protective film 210 and the second protective film 310 pressed together can move away from the first unwinding structure 200.

[0069] It is understood that a first pressure roller 430 channel is formed between the first pressure roller 430 and the second pressure roller 440. Thus, the first protective film 210 and the second protective film 310 located within the first pressure roller channel 410 can be rolled together under the action of the first pressure roller 430 and the second pressure roller 440, thereby achieving film coating of the product 700. Furthermore, when the first pressure roller 430 and the second pressure roller 440 roll the first protective film 210 and the second protective film 310, since the first pressure roller 430 and the second pressure roller 440 can rotate in opposite directions, the first protective film 210 and the second protective film 310, which are bonded together, can move away from the first unwinding structure 200 under the action of the first pressure roller 430 and the second pressure roller 440.

[0070] For example, the first pressure roller 430 can be driven to rotate by a rotary drive device, and / or the second pressure roller 440 can also be driven to rotate by a rotary drive device.

[0071] Preferably, to prevent the product 700 from being damaged when the first pressure roller 430 and the second pressure roller 440 roll against the first protective film 210 and the second protective film 310, the first pressure roller 430 and the second pressure roller 440 can be rubber rollers. It is understood that the rubber roller can undergo a certain deformation when it comes into contact with the product 700 between the first protective film 210 and the second protective film 310, thus avoiding rigid contact with the product 700.

[0072] In addition, in one embodiment, if the product 700 is thick, an elastic element may be connected to the first pressure roller 430 and / or the second pressure roller 440. The elastic element can play a buffering role when the first pressure roller 430 and the second pressure roller 440 come into contact with the product 700, so as to avoid damage to the product 700 when it is thick.

[0073] See Figure 1 and Figure 3 The roll forming structure 400 may further include a third pressure roller 450 and a fourth pressure roller 460. The third pressure roller 450 and the fourth pressure roller 460 are respectively rotatably disposed at one end of the first roll forming channel 410 away from the first unwinding structure 200. The rotation directions of the third pressure roller 450 and the fourth pressure roller 460 are opposite. The third pressure roller 450 and the fourth pressure roller 460 are arranged opposite to each other to form a second roll forming channel 420.

[0074] Preferably, the third pressure roller 450 and the fourth pressure roller 460 can be rubber rollers.

[0075] In another embodiment, the cooperation relationship and structural principle between the third pressure roller 450 and the fourth pressure roller 460 can be the same as the cooperation relationship and structural principle between the first pressure roller 430 and the second pressure roller 440, and will not be described again here.

[0076] Combination Figure 2 and Figure 4 In one embodiment, the feeding assembly may further include a feeding structure 600, which is used to feed the product 700 covered with a first protective film 210 and a second protective film 310.

[0077] In one embodiment, the feeding structure 600 includes a feeding plate 610, one end of which is connected to the first roller pressing channel 410, and the other end of the feeding plate 610 gradually tilts downward. It can be understood that in this embodiment, since the first roller pressing channel 410 does not subsequently drive the product 700 to continue moving, by connecting one end of the feeding plate 610 to the first roller pressing channel 410 and gradually tilting the other end downward, when the product 700, coated with the first protective film 210 and the second protective film 310, flows out of the first roller pressing channel 410, the product 700 can automatically fall onto the feeding plate 610 under the action of gravity.

[0078] Furthermore, a stop portion 611 is provided at one end of the feed plate 610 away from the first roller pressing channel 410. The stop portion 611 is used to stop the product 700 covered with the first protective film 210 and the second protective film 310, so that the product 700 can stay on the feed plate 610.

[0079] In one embodiment, if a second roller pressing channel 420 is also provided on one side of the first roller pressing channel 410, one end of the feed plate 610 is connected to the second roller pressing channel 420, and the other end of the feed plate 610 gradually tilts downward. It can be understood that after the product 700, coated with the first protective film 210 and the second protective film 310, flows out of the second roller pressing channel 420, the product 700 can automatically fall onto the feed plate 610 under the action of gravity.

[0080] See Figure 4 The unloading structure 600 may also include a first transfer drive 620 and an adsorption member 630. The first transfer drive 620 is disposed on one side of the unloading plate 610. The first transfer drive 620 is driven to connect with the adsorption member 630 so that the adsorption member 630 can adsorb the product 700 covered with the first protective film 210 and the second protective film 310 on the unloading plate 610, thereby realizing the unloading of the product 700 on the unloading plate 610.

[0081] Specifically, the adsorption element 630 can directly adsorb the second protective film 310 adhered to the first protective film 210. The adsorption element 630 can be a suction cup.

[0082] The feeding structure 600 may also include a receiving box 640, which is disposed on the end side of the feeding plate 610 and is used to receive the product 700 on the adsorption component 630.

[0083] It is understandable that transferring product 700 from the feed plate 610 to the receiving box 640 via the adsorption component 630 can prevent product 700 from accumulating on the feed plate 610, thereby affecting the outflow of product 700 from the roller pressing structure 400.

[0084] For example, the receiving box 640 may be located at the end of the unloading plate 610 away from the roller pressing structure 400.

[0085] Furthermore, the unloading structure 600 may also include a second transfer drive 650, which is driven to connect with the receiving box 640 so that the receiving box 640 can move toward or away from the unloading plate 610 to facilitate the subsequent unloading of the product 700 in the receiving box 640.

[0086] In addition, this application also provides a feeding mechanism, including a material transfer component and the feeding component in the above embodiments. The material transfer component is disposed on the support platform 100 and is used to transfer the product 700 onto the first protective film 210.

[0087] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of some utility models should be included within the protection scope of some utility models.
