[0001] This invention relates to the field of adhesive application equipment technology, and in particular to a winding device and a winding machine labeling device. Background Technology

[0002] In the existing technology, the production of some electronic devices usually involves adhesive application, that is, applying tape to certain positions of the electronic device. For some electronic devices, it is necessary to perform adhesive application operations in different positions. The electronic devices that need to be labeled are collectively referred to as the workpieces to be labeled.

[0003] Current labeling devices are all static adhesive application devices, which means that the workpiece to be labeled and the adhesive paper need to be fixed in place, and then the pressing mold is used to attach the adhesive paper to the workpiece.

Summary of the Invention

[0013] When the elastic component abuts against the first contact surface, the gap is formed between the pressure rod and the first side surface;

[0014] When the elastic component abuts against the second contact surface, the pressure rod abuts against the first side surface.

[0015] Optionally, the first abutment surface extends in a direction away from the second pivot and is inclined toward the second abutment surface; the second abutment surface extends in a direction away from the second pivot and is inclined toward the first abutment surface.

[0016] Optionally, the groove further has a bottom surface; the distance between the first pivot and the first limiting block in the first direction is D1mm, and the thickness of the first limiting block in the first direction is L1mm; the distance between the first pivot and the second limiting block in the second direction is D2mm, and the thickness of the second limiting block in the second direction is L2mm.

[0017] When the pressure bar contacts the bottom surface, the distance between the pressure bar and the first pivot is D3mm;

[0018] When the pressure bar contacts the first side, the distance between the pressure bar and the first pivot is D4mm;

[0019] Among them, the following conditions must be met: D1 < D4 < D1 + L1, D2 < D3 < D2 + L2.

[0026] Compared with the prior art, the winding device and winding machine labeling device of this invention have the following advantages:

[0027] In this embodiment of the invention, when it is necessary to wind the adhesive tape, the adhesive roller is first driven by the driving mechanism to rotate a certain angle in the first circumferential direction. Since the second pivot is set on the adhesive roller, the first pressure rod will also rotate in the first circumferential direction without the action of external force. During the rotation, the first limiting block contacts the first protrusion to apply an external force away from the first side to the first protrusion, so that the pressure rod can move away from the first side and form a gap between the pressure rod and the first side. At this time, one end of the adhesive tape along the length direction is placed into the gap. After the adhesive tape is placed, the drive mechanism drives the adhesive roller to rotate in the second circumferential direction. During the rotation, the first protrusion disengages from the first limiting block, allowing the pressure rod to disengage from the external force of the first limiting block. At this time, since the elastic component is always in contact with the second abutment surface, the elastic component pushes the pressure rod to rotate in the first circumferential direction and press it onto the first side surface through the mounting rod, thereby pressing the adhesive tape. After the adhesive tape is attached to the workpiece, the drive mechanism drives the adhesive roller to rotate in the second circumferential direction. During the rotation, the second limiting block contacts the first protrusion to apply an external force toward the first side surface. At the same time, the elastic component crosses the first abutment surface and abuts with the second abutment surface, so that the pressure rod is pressed back onto the first side surface under the force of the elastic component, thereby realizing one adhesive application cycle. The adhesive tape winding method of this application allows more adhesive tape to be wound in the same volume as the pressing mold, and the adhesive tape can be wound onto the adhesive roller by reversing the direction, giving the winding device of this application the advantages of small space occupation and simple adhesive application.

[0044] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0045] First, it should be noted that the directions such as top, bottom, upward, and downward mentioned in this article are defined relative to the directions in the various accompanying figures. They are relative concepts and therefore can change depending on their different positions and practical applications. Therefore, these or other directions should not be interpreted as restrictive terms.

[0047] Furthermore, it should be noted that any single technical feature described or implied in the embodiments herein, or any single technical feature shown or implied in the accompanying drawings, can still be combined among these technical features (or their equivalents) to obtain other embodiments of this application not directly mentioned herein.

[0048] It should also be understood that while the terms "first," "second," etc., are used in this document to describe various types of information, this information should not be limited to these terms, which are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0049] It should be noted that in different figures, the same reference numerals denote the same or substantially the same components.

[0050] The inventors of this application have discovered that labeling devices are all static adhesive application devices, which means that the workpiece 13 to be labeled and the adhesive paper need to be fixed statically, and then the pressing mold is used to attach the adhesive paper to the workpiece 13. This adhesive application method requires separate buffering mechanisms to buffer the workpiece 13 to be labeled and the adhesive paper, and then the pressing mold is used to attach the adhesive paper to the workpiece 13. This makes the overall labeling device occupy a large space, and the adhesive application area per operation depends on the size of the pressing mold, which leads to an increase in equipment cost.

[0051] Based on this, this application provides a labeling device for a winding machine, comprising: a frame, a moving mechanism, and a winding device. The frame has a preset channel 3 through which the workpiece 13 to be labeled passes. The moving mechanism is mounted on the frame and is used to drive the winding device closer to or away from the preset channel 3. Specifically, when it is necessary to attach adhesive tape to the workpiece 13 within the preset channel 3, the adhesive tape is first attached to the winding device. Then, the moving mechanism drives the winding device, after attaching the adhesive tape, closer to the preset channel 3 to attach the adhesive tape from the winding device to the workpiece 13 passing through the preset channel 3, thereby completing a labeling process.

[0052] like Figures 1-13 As shown in the preferred embodiment of the present invention, a winding device is used to wind adhesive paper, and includes: a mounting base 1, an adhesive roller 2, a driving mechanism, a pressure rod 4, and a limiting seat 7.

[0053] See Figure 3 and Figure 5The adhesive applicator roller 2 has an axial direction, a first circumferential direction, and a second circumferential direction opposite to the first circumferential direction. The axial direction refers to the direction passing through the axis of the adhesive applicator roller 2. Both the first axial direction and the second circumferential direction are circumferential directions around the axis of the adhesive applicator roller 2. The adhesive applicator roller 2 is rotatably mounted on the mounting base 1 via a first pivot 5, the axis of the first pivot 5 coinciding with the axis of the adhesive applicator roller 2. A groove 21 is formed on the adhesive applicator roller 2, the groove 21 penetrating the adhesive applicator roller 2 in the axial direction, and the groove 21 has a first side surface 211 and a second side surface 212 in the second circumferential direction.

[0054] The drive mechanism is used to drive the adhesive roller 2 to rotate, which achieves the rotation of the adhesive roller 2 relative to the mounting base 1 by driving the rotation of the first pivot 5.

[0055] See Figure 5 and Figure 8 The pressure rod 4 is pivotally connected to the adhesive roller 2 via the second pivot 17. The pressure rod 4 slides within the groove 21, allowing it to rotate relative to the second pivot 17 and move back and forth between the first side 211 and the second side 212. The pressure rod 4 is provided with a first protrusion 6.

[0056] See Figure 2 and Figure 8 The limiting seat 7 is mounted on the mounting base 1. The limiting seat 7 is provided with a first limiting block 8 and a second limiting block 9. The projections of the first limiting block 8 and the second limiting block 9 in the axial direction at least partially overlap with the projection of the first protrusion 6 in the axial direction, so that the first limiting block 8 and the second limiting block 9 can touch the first protrusion 6.

[0057] Among them, see Figure 5 When the drive mechanism drives the adhesive roller 2 to rotate in the first circumferential direction, it causes the first limiting block 8 to contact the first protrusion 6, thereby causing the pressure rod 4 to move away from the first side 211, so that a gap 10 for accommodating the adhesive paper is formed between the pressure rod 4 and the first side 211.

[0058] See Figure 3 When the drive mechanism drives the adhesive roller 2 to rotate in the second circumferential direction, it causes the second limiting block 9 to contact the first protrusion 6, thereby causing the pressure rod 4 to move toward the first side 211, so that the pressure rod 4 abuts against the first side 211 to press the adhesive paper.

[0059] Based on the above structure, see Figure 3 , Figure 3 This is the initial state of the winding device of this application. When it is necessary to wind the adhesive tape, this application first drives the adhesive roller 2 to rotate a certain angle along the first circumferential direction via the drive mechanism, that is, from... Figures 3 to 4 and Figure 5In this state, since the second pivot 17 is set on the adhesive roller 2, the first pressure rod 4 will rotate around the first circumferential direction even without external force. During the rotation, the first limiting block 8 contacts the first protrusion 6 to apply an external force away from the first side 211 to the first protrusion 6, so that the pressure rod 4 can move away from the first side 211, forming a gap 10 between the pressure rod 4 and the first side 211. At this time, one end of the adhesive paper along the length direction is placed into the gap 10. Then, by rotating the adhesive roller 2, the adhesive paper can be wound onto the adhesive roller 2. The method of winding the adhesive paper by the adhesive roller 2 in this application can wind more adhesive paper with the same volume as the pressing mold, and the adhesive paper can be wound onto the adhesive roller 2 by forward and reverse rotation, so that the winding device of this application has the advantages of small space occupation and simple adhesive application.

[0060] In one possible embodiment, see Figure 8 and Figure 9 This application also includes: a mounting rod 11 and an elastic component 12. The mounting rod 11 is pivotally connected to the adhesive roller 2 via a second pivot 17. The mounting rod 11 has a first mounting end 111 and a second mounting end 112, and a pressure rod 4 is disposed on the first mounting end 111. The axis of the second pivot 17 is parallel to the axial direction. The second mounting end 112 has a first abutment surface 1121 and abutment surface 1122. The first abutment surface 1121 and the second abutment surface 1122 are spaced apart along a first circumferential direction. The first abutment surface 1121 and the second side surface 212 are located on the same side of the mounting rod 11, and the second abutment surface 1122 and the first side surface 211 are located on the same side of the mounting rod 11.

[0061] Among them, see Figure 8 When the elastic component 12 abuts against the first contact surface 1121, it provides a pressure to the pressure rod 4 facing away from the first side surface 211, and a gap 10 is formed between the pressure rod 4 and the first side surface 211.

[0062] See Figure 3 and Figure 6 When the elastic component 12 abuts against the second contact surface 1122, it provides a pressure to the pressure rod 4 toward the first side surface 211. The pressure rod 4 abuts against the first side surface 211 so that the elastic component 12 can provide a clamping force to the pressure rod 4 to press the adhesive paper onto the first side surface 211.

[0063] Further, see Figure 8The first abutment surface 1121 extends away from the second pivot 17 and is inclined toward the second abutment surface 1122. The second abutment surface 1122 extends away from the second pivot 17 and is inclined toward the first abutment surface 1121, so that the second mounting end 112 of the mounting rod 11 is triangular. The first abutment surface 1121 and the second abutment surface 1122 are the two inclined surfaces of the triangular second mounting end 112. The end of the third limiting block 123 away from the elastic member 122 is an arc-shaped surface 1231. The arc-shaped surface 1231 can prevent the third limiting block 123 from jamming with the second mounting end 112 and can make the transition between the third limiting block 123 and the second mounting end 112 smoother.

[0064] Furthermore, the line connecting the second mounting end 112 and the second pivot 17 passes through the bottom surface 213 of the groove 21, so that when the third limiting block 123 abuts against the second abutting surface 1122, it can provide a clamping force to the pressure rod 4 to press the adhesive paper onto the first side surface 211.

[0065] Further, see Figure 8 and Figure 9 The elastic component 12 includes a first seat 121, an elastic element 122, and a third limiting block 123. The third limiting block 123 is used to abut against the first abutment surface 1121 or the second abutment surface 1122. The first seat 121 is disposed on the adhesive roller 2 so that the driving mechanism will drive the mounting rod 11 and the first seat 121 to rotate during the rotation of the adhesive roller 2, thereby keeping the first seat 121, the elastic element 122, the third limiting block 123, and the mounting rod 11 relatively stationary without external force. The first seat 121 has a sliding channel, the third limiting block 123 is slidably disposed in the sliding channel, and the elastic element 122 is disposed between the bottom surface of the sliding channel and the third limiting block 123, so that the third limiting block 123 can slide within the sliding channel under the action of the elastic element 122. The elastic element 122 is always in a compressed state, so that the elastic element 122 can push the third limiting block 123 to abut against the first abutting surface 1121 or the second abutting surface 1122.

[0066] Specifically, the extension direction of the sliding channel is perpendicular to the axial direction of the adhesive roller 2.

[0067] It is understandable that there are multiple ways to implement the elastic element 122, as long as it can produce elastic deformation and can connect the bottom surface 213 of the sliding channel and the third limiting block 123 respectively. For ease of implementation, the elastic element 122 can be in the form of a spring, with one end of the spring connected to the bottom surface of the sliding channel and the other end of the spring connected to the third limiting block 123.

[0068] Based on the above structure, the working process of the winding machine labeling device of this application will be described below:

[0069] See Figure 2 and Figure 3 In the initial state: the third limiting block 123 abuts against the second abutting surface 1122 so that the pressure rod 4 abuts against the first side surface 211 under the pressure of the elastic member 122 and the third limiting block 123.

[0070] When it is necessary to press one end of the adhesive tape into the gap 10, that is, from Figure 2 and Figure 3 Switch to Figure 4 and Figure 5 State: First, the adhesive roller 2 is driven to rotate a certain angle along the first circumferential direction by the drive mechanism. Since the second pivot 17 is set on the adhesive roller 2, the first pressure rod 4 will also rotate around the first circumferential direction without the action of external force. During the rotation, the first limiting block 8 contacts the first protrusion 6 to apply an external force away from the first side 211 to the first protrusion 6, so that the pressure rod 4 can move away from the first side 211, so that a gap 10 is formed between the pressure rod 4 and the first side 211. During this process, the third limiting block 123 always abuts against the second contact surface 1122. At this time, one end of the adhesive paper along the length direction is placed into the gap 10. After the adhesive tape is placed, the drive mechanism drives the adhesive roller 2 to rotate in the second circumferential direction. During the rotation, the first protrusion 6 disengages from the first limiting block 8 so that the pressure rod 4 is freed from the external force of the first limiting block 8. At this time, since the third limiting block 123 is always in contact with the second abutting surface 1122, the third limiting block 123 pushes the pressure rod 4 to rotate in the first circumferential direction and press it onto the first side surface 211 through the mounting rod 11, thereby achieving the pressing of the adhesive tape.

[0071] When it is necessary to wind the adhesive tape onto the adhesive roller 2, that is, from Figure 4 and Figure 5 Status switch to Figure 6 Status: After the adhesive tape is pressed, the adhesive roller 2 is driven to rotate in the second circumferential direction by the drive mechanism so that the adhesive tape can be wrapped around the adhesive roller 2 with the pressure bar 4 as the end.

[0072] When it is necessary to attach the adhesive paper wound on the adhesive roller 2 to the workpiece 13 to be adhered, that is, from Figure 6 Status switch to Figure 7 and Figure 8State: After the adhesive paper is attached to the adhesive roller 2, the adhesive roller 2 is driven to rotate in the first circumferential direction by the drive mechanism. During the rotation, the adhesive roller 2 contacts the workpiece 13 to be attached to attach the adhesive paper to the workpiece 13. During the rotation, the first limiting block 8 contacts the first protrusion 6 to apply an external force away from the first side 211 to the first protrusion 6, so that the pressure rod 4 can move away from the first side 211, so that a gap 10 is formed between the pressure rod 4 and the first side 211, so that the adhesive paper located in the gap 10 is detached from the gap 10 and completely attached to the workpiece 13 to be attached. During this process, the third limiting block 123 crosses the second abutment surface 1122 and abuts against the first abutment surface 1121, so that the pressure rod 4 abuts against the bottom surface 213 of the groove 21 and a gap 10 is formed between the pressure rod 4 and the first side 211.

[0073] When it is necessary to restore the initial state, that is, from Figure 7 and Figure 8 Status switch to Figure 2 and Figure 3 State: After the adhesive tape is attached to the workpiece 13 to be covered, the adhesive roller 2 is driven to rotate in the second circumferential direction by the drive mechanism. During the rotation, the second limiting block 9 contacts the first protrusion 6 to apply an external force toward the first side 211 to the first protrusion 6. At the same time, during this process, the third limiting block 123 crosses the first abutting surface 1121 and abuts the second abutting surface 1122, so that the pressure rod 4 is pressed back onto the first side 211 under the action of the third limiting block 123 and the elastic element 122, thereby realizing one adhesive application cycle.

[0074] In one possible embodiment, see Figure 14 and Figure 15 The groove 21 also has a bottom surface 213, and a first side surface 211 and a second side surface 212 are respectively disposed on opposite sides of the groove 21. The distance between the first pivot 5 and the first limiting block 8 in the first direction is D1mm, and the thickness of the first limiting block 8 in the first direction is L1mm. The distance between the first pivot 5 and the second limiting block 9 in the second direction is D2mm, and the thickness of the second limiting block 9 in the second direction is L2mm.

[0075] See Figure 14 and Figure 15 When the pressure rod 4 contacts the bottom surface 213, the distance between the pressure rod 4 and the first pivot 5 is D3mm.

[0076] See Figure 14 and Figure 15 When the pressure rod 4 contacts the first side 211, the distance between the pressure rod 4 and the first pivot 5 is D4mm.

[0077] Among them, the following conditions must be met: D1 < D4 < D1 + L1, D2 < D3 < D2 + L2. Since the second pivot 17 is set on the adhesive roller 2, and the first pivot 5 and the second pivot 17 are not coaxial, the distance between the pressure rod 4 and the first pivot 5 when it contacts the first side surface 211 is not the same as the distance between the pressure rod 4 and the first pivot 5 when it contacts the bottom surface 213. Therefore, when the pressure rod 4 contacts the first side surface 211, D1 < D4 < D1 + L1 must be met so that the first limiting block 8 can contact the pressure rod 4 during the rotation of the adhesive roller 2; when the pressure rod 4 contacts the bottom surface 213, D2 < D3 < D2 + L2 must be met so that the second limiting block 9 can contact the pressure rod 4 during the rotation of the adhesive roller 2.

[0078] Furthermore, in order to enable the adhesive paper to adhere better to the adhesive roller 2, this application also includes an adsorption component. The adhesive roller 2 has a plurality of adsorption holes 22 for adsorbing the adhesive paper; the adsorption component is connected to the adsorption holes 22, and the adsorption component generates negative pressure on the adsorption holes 22 so that the adhesive paper can be stably adhered to the adhesive roller 2.

[0079] Understandably, there are multiple ways to implement an adsorption component, as long as it can generate negative pressure on the adsorption pores 22. For ease of implementation, the adsorption component can be implemented using a negative pressure vacuum pump to generate negative pressure on the adsorption pores 22.

[0080] Further, see Figure 10 The labeling device of the winding machine of this application includes a first winding device 14 and a second winding device 15. The first winding device 14 and the second winding device 15 are respectively arranged on both sides of the preset channel 3. That is, the number of winding devices in this application is two, so as to enable the application of adhesive to both sides of the workpiece 13 to be labeled.

[0081] Further, see Figure 10 The moving mechanism includes a slide rail 16. The mounting base 1 of the first winding device 14 is slidably mounted on the slide rail 16, and the mounting base 1 of the second winding device 15 is slidably mounted on the slide rail 16, so that the moving mechanism can drive the first winding device 14 and the second winding device 15 to slide on the slide rail 16, thereby moving closer to or away from the workpiece 13 to be bonded.

[0082] For example, the moving mechanism can be configured with two cylinders, each of which moves the first winding device 14 on the slide rail 16 by extending or retracting its output shaft.

[0083] It is understood that the above is only an example of one embodiment of the moving mechanism. In other embodiments of this application, the moving mechanism may also be a hydraulic cylinder, a lead screw and nut structure, etc., as long as the first winding device 14 and the second winding device 15 can slide on the slide rail 16.

[0084] In summary, the embodiments of the present invention provide a winding device and a winding machine labeling device, which can wind adhesive paper onto the adhesive roller 2 by rotating the adhesive roller 2.
