DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] See also Figure 1-Figure 10 , the present invention provides a technical solution:

[0051] The automatic feeding adhesive tape sticking machine comprises a feeding mechanism 1 and an adhesive tape sticking mechanism 4, wherein the feeding mechanism 1 is used to convey the workpiece, and the adhesive tape sticking mechanism 4 is used to stick the tape to the workpiece. The above feeding mechanism 1 and adhesive tape sticking mechanism 4 are both prior arts, and their specific structures and working principles are not described in detail here.

[0052] Different from the prior art, the adhesive tape applying machine of the present invention further comprises a first bracket 2, a second bracket 3 and a lifting mechanism 5, and the functions of these three structures are described in detail below.

[0053] In the present invention, the feeding mechanism 1 includes a first driven conveyor belt 11, an active conveyor belt 12 and a second driven conveyor belt 13 arranged transversely; wherein the active conveyor belt 12 is driven by a driving motor 123; the active conveyor belt 12 and the second driven conveyor belt 13 are both arranged below the first driven conveyor belt 11, Figure 1 It can be seen that the left end of the active conveyor belt 12 is kept flush with the left end of the first driven conveyor belt 11, so that dust and other impurities in the environment are difficult to fall onto the upper surface of the active conveyor belt 12 by deposition, thereby largely preventing dust from falling onto the upper surface of the active conveyor belt 12, and then the surface of the workpiece transported by the active conveyor belt 12 will not be contaminated by dust and other impurities on the active conveyor belt 12, thereby ensuring the cleanliness of the workpiece. Moreover, there are conveying channels for the workpiece to pass between the active conveyor belt 12 and the first driven conveyor belt 11, and between the second driven conveyor belt 13 and the first driven conveyor belt 11. In other words, the active conveyor belt 12 and the second driven conveyor belt 13 are at the same height, and the height of the first driven conveyor belt 11 is higher than that of the active conveyor belt 12, so that conveying channels for conveying workpieces are formed between the active conveyor belt 12 and the first driven conveyor belt 11, and between the second driven conveyor belt 13 and the first driven conveyor belt 11.

[0054] The loading process of the loading mechanism 1 is as follows: the active conveyor belt 12 is started, and the workpiece is fed from between the left end of the first driven conveyor belt 11 and the left end of the active conveyor belt 12 to between the first driven conveyor belt 11 and the active conveyor belt 12. At this time, since the first driven conveyor belt 11 and the active conveyor belt 12 clamp the workpiece in the middle, there is a large friction force between the workpiece and the active conveyor belt 12, so that the workpiece can be transported. At the same time, the friction force will also drive the first driven conveyor belt 11 to passively operate to realize the transportation of the workpiece; when one end of the workpiece is between the first driven conveyor belt 11 and the active conveyor belt When one end of the workpiece is completely withdrawn from between the first driven conveyor belt 11 and the active conveyor belt 12 and the other end is between the first driven conveyor belt 11 and the second driven conveyor belt 13, the second driven conveyor belt 13 will also start to operate under the action of friction; when one end of the workpiece is completely withdrawn from between the first driven conveyor belt 11 and the active conveyor belt 12, the workpiece is now partially or completely between the first driven conveyor belt 11 and the second driven conveyor belt 13. At this time, since the first driven conveyor belt 11 is in operation under the action of the next workpiece, the workpiece that is partially or completely between the first driven conveyor belt 11 and the second driven conveyor belt 13 can also be discharged.

[0055] When the workpiece is being transported, the adhesive tape sticking mechanism 4 will stick the adhesive tape to the lower surface of the moving workpiece. The specific implementation method and principle are as follows:

[0056] like Figure 1 and Figure 3 As shown, an accommodating space is reserved between the active conveyor belt 12 and the second driven conveyor belt 13, and the gluing portion at the top of the tape pasting mechanism 4 (the gluing portion at the top of the tape pasting mechanism 4 refers to the functional component for pasting the tape to the lower surface of the workpiece, which is the prior art and will not be described in detail here) and the cleaning mechanism 6 for cleaning impurities are both arranged in the accommodating space, and the cleaning mechanism 6 is located between the active conveyor belt 12 and the tape pasting mechanism 4; during actual work, the cleaning mechanism 6 first cleans the lower surface of the workpiece and the surface of the active conveyor belt 12, and then pastes the tape to the lower surface of the workpiece through the tape pasting mechanism 4 to ensure the pasting quality of the tape.

[0057] The first driven conveyor belt 11 is installed on the first bracket 2; the active conveyor belt 12 and the second driven conveyor belt 13 are both installed on the second bracket 3; the lifting mechanism 5 is arranged at the bottom of the second bracket 3, and is used to adjust the height of the second bracket 3; in this embodiment, the lifting mechanism 5 adopts an electric push rod, that is, the height of the second bracket 3 is adjusted by controlling the extension and retraction of the electric push rod, so as to complete the adjustment of the distance between the active conveyor belt 12 and the second driven conveyor belt 13 and the first driven conveyor belt 11 (that is, the vertical height of the conveying channel).

[0058] like Figure 3 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the cleaning mechanism 6 includes a roller 63 and a wiping cylinder 64. The axial direction of the roller 63 is parallel to the axial direction of the active roller 122 of the active conveyor belt 12. The roller 63 can be made of metal materials such as stainless steel, and the wiping cylinder 64 can be made of materials that can wipe off impurities such as sponge. The wiping cylinder 64 is fixedly sleeved on the outer side of the roller 63. The fixing method between the cylinder 64 and the roller 63 is not specifically limited in this embodiment. For example, it can be fixed by adhesive. The height of the top of the wiping cylinder 64 is the same as the height of the top surface of the active conveyor belt 12. In this way, the distance between the top of the wiping cylinder 64 and the lower surface of the first driven conveyor belt 11 is consistent with the vertical height of the conveying channel, and the workpiece can pass smoothly between the cleaning mechanism 6 and the first driven conveyor belt 11; and the wiping cylinder 64 is in contact with the conveying belt of the active conveyor belt 12. The purpose of this setting method is that the wiping cylinder 64 can not only clean the impurities on the lower surface of the workpiece, but also clean the impurities on the conveying belt surface of the active conveyor belt 12.

[0059] When the active conveyor belt 12 conveys the workpiece, it can drive the roller 63 to rotate, and the rotation direction of the roller 63 is opposite to the rotation direction of the active roller 122 .

[0060] In the above scheme, the workpiece can be transported through the cooperation between the first driven conveyor belt 11, the active conveyor belt 12 and the second driven conveyor belt 13, and because the glue-sticking part at the top of the tape sticking mechanism 4 and the cleaning mechanism 6 for cleaning impurities are both arranged in the accommodating space, and the cleaning mechanism 6 is located between the active conveyor belt 12 and the tape sticking mechanism 4, therefore, on the one hand, the operation of sticking tape on the lower surface of the workpiece can be realized, and dust and other impurities in the external environment can be effectively prevented from falling to the lower surface of the workpiece due to deposition and other factors. On the other hand, the cleaning mechanism 6 can also wipe and clean the impurities adhering to the lower surface of the workpiece before sticking the tape. At the same time, the impurities on the conveyor belt surface of the active conveyor belt 12 can also be cleaned. In this way, dust and other impurities can be prevented from affecting the stability of the tape after sticking, thereby improving the quality of tape sticking.

[0061] Furthermore, in view of the presence of stubborn impurities on the lower surface of the workpiece and the surface of the conveyor belt of the active conveyor belt 12 that are difficult to wipe off, the present invention adopts the following technical means to deal with them.

[0062] One end of the active roller 122 is fixedly connected to a driving gear 124, and a driving motor 123 is fixedly mounted on the second bracket 3. The output shaft of the driving motor 123 is coaxially fixedly connected to the other end of the active roller 122 through a coupling. When the driving motor 123 is started, the active roller 122 can be driven to rotate, so that the active conveyor belt 12 can be operated.

[0063] The cleaning mechanism 6 also includes a driven gear 61, an end tube 62, a fixed shaft 65, a fixed tube 67 and a slide post 68; specifically, the connection relationship and position relationship between the various components are as follows: the end tube 62 is coaxially arranged with the roller 63, and the two end tubes 62 are axially slidably sleeved on both ends of the roller 63, that is, the end tube 62 can only perform linear motion in the axial direction of the roller 63, and there will be no relative rotation between the end tube 62 and the roller 63. Therefore, when the end tube 62 rotates, it will also directly drive the roller 63 to rotate together, so that This causes the wiping cylinder 64 fixed on the outside of the roller 63 to rotate; the fixed shaft 65 is coaxially arranged with the roller 63, the fixed shaft 65 passes through the roller 63, and the two ends of the fixed shaft 65 extend out of the roller 63 and further extend to the outside of the two end cylinders 62, and both ends of the fixed shaft 65 are fixedly mounted on the second bracket 3 through the support 66, so that the fixed shaft 65 can maintain a stable state, and the two end cylinders 62 are rotatably connected to the fixed shaft 65 through bearings, that is, the end cylinder 62 can stably rotate around the fixed shaft 65.

[0064] The driven gear 61 is meshed with the driving gear 124, and the driven gear 61 is coaxially fixed on one of the end tubes 62 (here one of the end tubes 62 refers to the end tube 62 adjacent to the driven gear 61). In this way, when the driving gear 124 rotates, the driven gear 61 will also rotate, and the rotation direction of the driven gear 61 is opposite to the rotation direction of the driving gear 124, thereby driving the end tube 62, the roller 63 and the wiping tube 64 to rotate to wipe off impurities on the lower surface of the workpiece and the surface of the conveyor belt of the active conveyor belt 12.

[0065] The fixed cylinder 67 is coaxially arranged inside the roller 63, and the fixed cylinder 67 is fixedly connected to the fixed shaft 65 (for example, the fixed cylinder 67 and the fixed shaft 65 can be fixedly connected by bolts or by welding, which is not specifically limited here), and an annular bevel groove 671 is provided on the outer circumferential surface of the fixed cylinder 67; one end of the slide column 68 is fixedly connected to the inner surface of the roller 63, and the other end of the slide column 68 is inserted into the inside of the annular bevel groove 671; in actual practical application, since the fixed cylinder 67 is fixedly connected to the fixed shaft 65, and the fixed shaft 65 is fixedly installed on the second bracket 3 through the support 66, the fixed cylinder 67 remains stationary, and the roller 63 will start to rotate after the active conveyor belt 12 is started. It is fixedly connected to the roller 63, so the slide post 68 will rotate with the roller 63, and because the other end of the slide post 68 is inserted into the inside of the annular bevel groove 671, the slide post 68 will be limited by the annular bevel groove 671 during rotation and perform linear reciprocating motion along the axial direction of the fixed shaft 65, that is, the roller 63 will perform linear reciprocating motion along the axial direction of the fixed shaft 65. In this way, on the one hand, the roller 63 drives the wiping drum 64 to rotate to clean impurities on the lower surface of the workpiece and the conveyor belt surface of the active conveyor belt 12. On the other hand, the roller 63 can also drive the wiping drum 64 to perform linear reciprocating motion along the axial direction of the fixed shaft 65 to further clean impurities on the lower surface of the workpiece and the conveyor belt surface of the active conveyor belt 12.

[0066] In order to further improve the effect of cleaning impurities, a plurality of annular grooves 641 are provided on the outer circumference of the wiping cylinder 64. The advantages of providing the annular grooves 641 are: first, the roughness of the outer circumference of the wiping cylinder 64 can be increased, the friction force on the surface of the wiping cylinder 64 can be increased, and the cleaning effect can be improved; second, since the wiping cylinder 64 can perform linear reciprocating motion in the axial direction of the fixed shaft 65, the annular grooves 641 can scrape the lower surface of the workpiece and the conveyor belt surface of the active conveyor belt 12, and the cleaning effect is good. Moreover, the annular grooves 641 can also be used to provide a discharge channel for the scraped dust and other impurities, prevent the accumulation of impurities, and avoid impurities from scratching the workpiece and the conveyor belt of the active conveyor belt 12, further improving the sticking quality of the adhesive tape. In this embodiment, the width of the annular groove 641 in the axial direction of the wiping cylinder 64 should be smaller than the amplitude of the linear reciprocating motion of the wiping cylinder 64 in the axial direction of the fixed shaft 65, so as to ensure that the impurities are cleaned thoroughly and completely.

[0067] The structure and principle for realizing axial sliding between the end tube 62 and the roller 63 are as follows: the outer circumference of the end tube 62 is provided with a key groove 621 arranged parallel to its axial direction; the inner circumference of the roller 63 is fixed with a positioning key 631 arranged parallel to its axial direction; the positioning key 631 is slidably arranged inside the key groove 621; due to the mutual cooperation between the positioning key 631 and the key groove 621, the end tube 62 and the roller 63 can only perform linear motion along the axial direction of the roller 63, and there will be no relative rotational motion between the end tube 62 and the roller 63.

[0068] In order to prevent the workpiece from being displaced during the reciprocating linear motion of the wiping drum 64, and also to improve the stability and accuracy of the workpiece during transportation, the adhesive tape sticking machine also includes an alignment mechanism 7, and the alignment mechanism 7 includes two alignment plates 71 arranged on the upper surface of the active conveyor belt 12. The alignment plates 71 are slidably connected to the conveyor belt of the active conveyor belt 12. The alignment plates 71 can always be located on the conveyor belt of the active conveyor belt 12 and will not rotate with the conveyor belt. The workpiece can pass between the two alignment plates 71, thereby realizing the alignment of the workpiece and ensuring that the adhesive tape can be stuck to the specified position of the workpiece.

[0069] Among them, the two ends of the two alignment plates 71 that are far away from each other are both provided with a screw rod 73 and a guide rod 74, one end of the screw rod 73 is rotatably connected to the alignment plate 71 (for example, through a suitable bearing), and one end of the guide rod 74 is fixedly connected to the alignment plate 71 (for example, welding); the screw rod 73 threadably penetrates the mounting plate 72, that is, rotating the two screw rods 73 can respectively drive the two alignment plates 71 to approach or move away from each other to adapt to the size of the workpiece, the guide rod 74 slides through the mounting plate 72 through the guide sleeve 75, and the mounting plate 72 is fixedly mounted on the conveyor belt frame 121 of the active conveyor belt 12.

[0070] The first bracket 2 includes a vertical support plate 21, a slide rail 22 and a slider 23; the top of the vertical support plate 21 is fixedly connected to the first driven conveyor belt 11 for supporting the first driven conveyor belt 11; the slide rail 22 is vertically arranged and fixedly connected to the vertical support plate 21; the slider 23 is slidably installed on the slide rail 22, and the slider 23 is fixedly connected to the active conveyor belt 12 and the second driven conveyor belt 13, so as to realize the sliding connection between the active conveyor belt 12 and the second driven conveyor belt 13 and the vertical support plate 21, so that when the height of the active conveyor belt 12 and the second driven conveyor belt 13 is adjusted by the lifting mechanism 5, the active conveyor belt 12 and the second driven conveyor belt 13 can remain stable.

[0071] The second bracket 3 includes a bottom plate 31, a top frame 32, and a plurality of oblique connecting plates 34 fixedly connected between the bottom plate 31 and the top frame 32; the active conveyor belt 12 and the second driven conveyor belt 13 are both fixedly connected to the top frame 32 via a vertical plate 33; reinforcing ribs 35 are fixed inside the top frame 32, and the reinforcing ribs 35 are used to improve the overall structural strength of the top frame 32.

[0072] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
