Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application specification, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

In addition, the terms "first", "second", "third" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0045] In the description of the embodiments of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be a fixed connection, or a replaceable connection, or an integral connection, it can be a mechanical connection, or an electrical connection, it can be a direct connection, or an indirect connection through an intermediate medium, it can be a communication inside two elements. For those of ordinary skill in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0046] Referring to Figures 1 to 3 A product tape and waste tape separation mechanism is provided in the embodiments of the present application, which comprises a conveying assembly 10 and a guide and adsorption assembly 20.

[0047] The conveying assembly 10 is provided with a conveying surface 11 for conveying the tape 100. The guide and adsorption assembly 20 has a waste tape adsorption surface. As Figure 2 shown, the cut tape 100 is divided into a product tape 110 and a waste tape 120. The waste tape adsorption surface can generate an adsorption force on the tape 100 on the conveying surface 11, so that the product tape 110 and the waste tape 120 in the tape 100 are separated.

[0048] In the embodiments, the waste tape adsorption surface comprises a guide adsorption surface 22 and a separation adsorption surface 21; the separation adsorption surface 21 faces the conveying surface 11; the guide adsorption surface 22 is connected with the separation adsorption surface 21, and the distance between the guide adsorption surface 22 and the conveying surface 11 increases along the conveying direction. The conveying direction refers to the direction in which the tape 100 is conveyed.

[0049] The separation adsorption surface 21 is located upstream of the guide adsorption surface 22, which can drive the waste tape 120 and the product tape 110 to separate by generating an adsorption force. Since the guide adsorption surface 22 is connected with the separation adsorption surface 21, the separated product tape 110 can be conveyed to the guide adsorption surface 22 and transferred to the next station, such as a waste collection pipe 60, by the guidance of the guide adsorption surface 22.

[0050] In the prior art, after the waste tape 120 and the product tape 110 are separated, the product tape 110 is continuously conveyed to the next station, and the waste tape 120 separated from the product tape 110 is transferred to the waste collection station; however, since the separated waste tape 120 does not have a supporting force, the risk of breaking the waste tape 120 is high, thereby affecting the continuous collection of the waste tape 120 and the continuous production of the whole production.

[0051] Moreover, in the case of only providing the separation adsorption surface 21, there is a situation that the tape separation between the product tape 110 and the waste tape 120 is not complete; in the case of only providing the guide adsorption surface 22, the guide adsorption surface 22 will directly separate the waste tape 120 from the product tape 110 by adsorption force and move away, so that the waste tape 120 that is not separated will be completely separated from the product tape 110 when entering the adsorption area of the guide adsorption surface 22, resulting in a high risk of product tape deformation and a high risk of waste tape breaking.

[0052] In the embodiment, the separating and adsorbing surface 21 can adsorb the material belt 100 on the conveying surface 11 during the conveying of the material belt 100 on the conveying surface 11, so that the product material belt 110 and the waste material belt 120 are preliminarily separated. Then, with the further conveying of the material belt 100, the waste material belt 120 is adsorbed and conveyed along the guiding and adsorbing surface 22, so that the distance between the product material belt 110 and the waste material belt 120 is increased. In this way, the product material belt 110 and the waste material belt 120 can be completely separated, and the risk of the waste material belt 120 being broken due to a large instantaneous pulling force is reduced. The guiding and adsorbing surface 22 can provide adsorbing force as the supporting force for the waste material belt 120 during the transferring of the waste material belt after the separation to the waste material collecting station, so that the risk of the waste material belt 120 being broken is further reduced, and the continuous operation of the waste material collecting operation is ensured.

[0053] It should be noted that the way in which the waste material belt 120 and the product material belt 110 are separated by the adsorbing force generated by the separating and adsorbing surface 21 can be realized by the prior art, and the length and adsorbing force required by the separating and adsorbing surface 21 and other parameters can be set according to actual needs, which will not be described in detail in the embodiment.

[0054] In one embodiment, please refer to Figure 4 , the included angle α formed between the separating and adsorbing surface 21 and the guiding and adsorbing surface 22. In the embodiment, the included angle α is obtuse.

[0055] In a more specific embodiment, the included angle α is greater than or equal to 135° and less than or equal to 180°. The present inventor has found that, within this angle range, the transition of the waste material belt 120 between the separating and adsorbing surface 21 and the guiding and adsorbing surface 22 is good and the waste material belt 120 is not easy to break.

[0056] In one embodiment, please refer to Figures 1 to 5 , the conveying surface 11 is provided with a conveying adsorbing surface 12; the conveying adsorbing surface 12 is used to adsorb the material belt 100 or the product material belt 110 separated from the material belt 100.

[0057] As shown in Figure 5 , after the material belt 100 is unwound from the unwinding roller 200 and passes through the conveying surface 11, the product material belt 110 is wound by the winding roller 300 after the waste material belt 120 is separated on the conveying surface 11. In the embodiment, the conveying adsorbing surface 12 provided on the conveying surface 11 can better fix the material belt 100 and the product material belt 110, so that the product material belt 110 can be separated from the waste material belt 120, and the product material belt 110 is prevented from being separated from the conveying surface 11 due to being pulled by the waste material belt 120 during the separation process.

[0058] It should be noted that, in the embodiment, the entire conveying surface 11 can be provided as the conveying adsorbing surface 12, or part of the conveying surface 11 can be provided as the conveying adsorbing surface 12.

[0059] In one embodiment, the adsorption pipe connected with the conveying adsorption surface 12 and / or the waste belt adsorption surface has several, and the internal flow capacity of the adsorption pipe is adjustable.

[0060] Specifically, the conveying adsorption surface 12 and the waste belt adsorption surface are connected with the vacuum control system through the adsorption pipe, so that the vacuum control system can provide the conveying adsorption surface 12 and the waste belt adsorption surface with a vacuum adsorption force. In this embodiment, the adsorption pipe can be provided with an adjustable tool such as an electrically controlled valve, a manually controlled valve, etc., so that the internal flow capacity of the adsorption pipe is adjustable, and thus the worker can adjust the adsorption force of the conveying adsorption surface 12 and / or the waste belt adsorption surface. In addition, the internal flow capacity of the adsorption pipe can be adjusted to a state of being cut off, i.e., the adsorption pipe is in a state of being unable to communicate with an internal flow capacity of zero.

[0061] In one embodiment, please refer to Figures 1 to 7 , the adsorption area of the conveying adsorption surface 12 and the adsorption area of the waste belt adsorption surface are staggered with each other, or the adsorption area of the conveying adsorption surface 12 and the adsorption area of the waste belt adsorption surface are embedded with each other.

[0062] In this embodiment, the conveying adsorption surface 12 and the waste adsorption surface can respectively adsorb different areas to form a staggered or embedded layout, so that one can provide the product belt 110 with an adsorption force, and the other can provide the waste belt 120 with an adsorption force. In the manner provided in this embodiment, the product belt 110 and the waste belt 120 can be directly separated and guided to the next respective workstations, realizing a stable belt guiding process.

[0063] Taking the conveying of the belt 100 along the vertical plane as an example. The projection of the adsorption area of the conveying adsorption surface 12 on the vertical plane is the a area, and the projection of the adsorption area of the waste belt adsorption surface on the vertical plane is the b area.

[0064] As an embodiment, please refer to Figure 6 , Figure 6 for an example diagram when the a area and the b area are staggered with each other. In this manner, the a area and the b area can have overlapping parts, contact each other, or have a gap between each other, specifically so that the a area and the b area can respectively adsorb different ranges.

[0065] As another embodiment, please refer to Figure 7 , Figure 6An example diagram of the a region and the b region being mutually embedded. In this mode, the edges of the a region and the b region can be irregular shapes, and the edges of the two regions are in abutment with each other, so that the a region and the b region can cover the entire material belt 100 after being combined. In actual applications, the edge shape of the a region and the edge shape of the b region can be set according to the cutting path of the product material belt 110 and the waste material belt 120.

[0066] In actual applications, the shapes of the a region and the b region can be adjusted by adjusting the shapes, numbers, and arrangement rules of the adsorption holes on the conveying adsorption surface 12 and the waste material belt adsorption surface.

[0067] In one embodiment, the size of the adsorption area of the conveying adsorption surface 12 and / or the waste material belt adsorption surface can be adjusted and set.

[0068] The conveying adsorption surface 12 and / or the waste material belt adsorption surface is provided with a plurality of adsorption holes, and the adsorption force is generated through the adsorption holes. Taking the guide adsorption surface 22 in the waste material belt adsorption surface as an example, please refer to Figure 8 A movable adjusting shielding plate 23 can be arranged at the back of the guide adsorption surface 22. The shielding plate 23 can be arranged inside the guide adsorption assembly 20. By adjusting the position of the shielding plate 23, the number of adsorption holes with adsorption force on the guide adsorption surface 22 can be adjusted, thereby adjusting the size of the adsorption area.

[0069] In another embodiment, the conveying adsorption surface 12 and / or the waste material belt adsorption surface is connected to a plurality of negative pressure cavities, and the negative pressure cavities are connected to adsorption pipes.

[0070] In this embodiment, the conveying adsorption surface 12 and the waste material belt adsorption surface generate adsorption force through the respective connected negative pressure cavities. By controlling the internal flow of each adsorption pipe, the size of the adsorption force of each negative pressure cavity can be controlled, thereby adjusting the size of the adsorption force of different regions on the conveying adsorption surface 12 and the waste material belt adsorption surface.

[0071] When the internal flow of the adsorption pipe is adjusted to the state that the adsorption pipe is blocked, the negative pressure cavity connected to the adsorption pipe stops generating adsorption force, and correspondingly, the region of the conveying adsorption surface 12 and the waste material belt adsorption surface connected to the negative pressure cavity stops generating adsorption force.

[0072] In the case that the conveying adsorption surface 12 and the waste material belt adsorption surface are connected to a plurality of negative pressure cavities, by controlling some negative pressure cavities to stop generating adsorption force, the adsorption area on the conveying adsorption surface 12 and the waste material belt adsorption surface can be adjusted, thereby achieving the effect of adjustable adsorption area size.

[0073] By adjusting the size of the adsorption area, the adsorption area of the conveying adsorption surface 12 can be adapted to the product tape 110, and / or the adsorption area of the waste tape adsorption surface can be adapted to the waste tape 120. On the one hand, more accurate adsorption and guidance can be provided to enable the tape 100 to be stably separated, and on the other hand, the mechanism can be adapted to different sizes of the tape 100, thereby improving the applicability of the mechanism.

[0074] In one embodiment, referring to Figure 4 or Figure 6 , the conveying assembly 10 and / or the waste tape adsorption surface is provided with a conveyable belt 30; the belt 30 is provided with adsorption holes 31.

[0075] Taking the example that the conveying assembly 10 and the waste tape adsorption surface are both provided with a conveyable belt 30; the belt 30 can be conveyed on the waste tape adsorption surface and the conveying assembly 10 under the drive of the belt driving assembly, so as to drive the tape 100, the product tape 110 or the waste tape 120 to be conveyed; at the same time, the belt 30 is provided with adsorption holes, which can adsorb the material.

[0076] In one embodiment, referring to Figure 5 , the mechanism further comprises a tape guiding assembly 40; the tape guiding assembly 40 is arranged on the conveying assembly 10, and is used for allowing the product tape 110 in the tape 100 to pass through and limiting the waste tape 120 from passing through.

[0077] The tape guiding assembly 40 can play a role of guiding the tape and avoiding the unseparated waste tape 120 from passing through, so as to ensure that the waste tape 120 and the product tape 110 are separated.

[0078] In one embodiment, the mechanism further comprises a burr removing piece 50; the burr removing piece 50 is arranged on the conveying assembly 10, and is used for rubbing the edge of the product tape 110 and / or adsorbing the burr of the edge of the product tape 110.

[0079] In one embodiment, referring to Figure 9 , the product tape and waste tape separation mechanism further comprises a waste collecting pipe 60 and a slide rail 70; the waste collecting pipe 60 is slidably arranged on the slide rail 70; the waste collecting pipe 60 is directed towards the guiding adsorption surface 22.

[0080] The waste collecting pipe 60 can be arranged at the end of the guiding adsorption surface 22, so that the guiding adsorption surface 22 can guide the waste tape 120 to the waste collecting pipe 60, and provide adsorption force for the waste tape 120 in the process of transferring the waste tape 120 into the waste collecting pipe 60.

[0081] In this embodiment, the position of the waste collecting pipe 60 can be adjusted by the slide rail 70 to adapt to the position of the guiding adsorption assembly 20.

[0082] The above is the preferred embodiment of the application and is not intended to limit the application. Although the application is described in detail with reference to the examples, those skilled in the art can modify the technical solutions described in the examples or make equivalent replacements for some of the technical features, but any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the application shall be included in the protection scope of the application.
