Description

Technical Field

[0001] This utility model relates to the field of tape processing technology, and in particular to a single-sided tape folding and pasting device. Background Technology

[0002] In industrial production and daily applications, adhesive tape is a commonly used bonding material, and its ease of use and reliability are of great concern. To facilitate the tearing and use of adhesive tape, a folded "pull tab" structure is usually formed at the end of the tape. This pull tab can serve as a tearing starting point for user convenience.

[0003] For example, in the field of water pump testing (such as diaphragm booster pumps for water purifiers), since the pump is not pre-installed with a compatible base during testing, the pre-drilled screw holes on the pump (for mounting the base) are at risk of water ingress during various performance tests (such as water seal performance tests), potentially leading to corrosion and damage. Currently, the common practice is to manually fold tape to form a strip with a pull tab before attaching it to the screw holes for sealing; after testing, the tape can be easily peeled off by pinching the pull tab. However, manually folding the pull tab may result in direct contact with the adhesive surface of the tape, easily causing dust and fingerprints to adhere, reducing adhesion and affecting the bonding effect, especially in water pump sealing applications. Furthermore, manual operation is inefficient.

[0004] Some existing technologies (such as the tape bonding device described in patent publication number CN222808411U) use a conveyor assembly to move the target workpiece under the tape, and then use the adhesive force between the workpiece and the tape to pull out the tape before folding it to form a pull head. This method requires the target workpiece (the workpiece to be taped) and the conveyor assembly as the driving structure for pulling out the tape, and is only suitable for workpieces with regular shapes and large bonding surfaces. For irregularly shaped workpieces, small workpieces, or uneven bonding surfaces, it cannot stably drive the tape to be pulled out, resulting in extremely poor applicability; for example, applying tape to water pump screw holes. In addition, in the above-mentioned methods that rely on the target workpiece, the tape is directly adhered to the surface of the workpiece during the pulling process, and the tape and workpiece form an integral structure, making it impossible to manufacture a separate, flexible section of tape with a pull head. This means that the tape bonding device can only be used for one-time bonding of specific workpieces and cannot be used for bonding other products according to customer requirements, especially it is not suitable for bonding and sealing water pump screw holes as mentioned above.

[0005] Therefore, there is a need for a device that can independently produce tape pull heads without relying on a target workpiece. Utility Model Content

[0006] This utility model provides a single-sided tape folding and pasting device to achieve the independent formation of a section of tape with a pull head without relying on a target workpiece.

When the second adsorption head is in the first position, the first adsorption surface and the second adsorption surface are flush.

[0008] Preferably, the auxiliary fixing mechanism is configured to adsorb and position the first segment of the tape carried on the adsorption plate after the folding mechanism moves from the first point to the second point.

[0009] Preferably, the folding mechanism is configured such that after the folding mechanism moves from the first point to the second point, the first adsorption head and the second adsorption head adsorb and position the second segment of the tape; the folding and pasting device further includes a cutting mechanism located between the first segment and the second segment, so as to cut the tape at the position between the first segment and the second segment when the first segment and the second segment are respectively adsorbed and positioned by the auxiliary fixing mechanism and the folding mechanism.

[0010] Preferably, the folding and pasting device further includes: a material-picking mechanism configured to move to a material-picking point to adsorb and position the third segment of the tape after the folding mechanism moves from the first point to the second point, the material-picking point being located between the first point and the second point; and a cutting mechanism located between the first segment and the third segment to cut the tape at a position between the first segment and the third segment, provided that the first segment and the third segment are respectively adsorbed and positioned by the auxiliary fixing mechanism and the material-picking mechanism.

[0011] Preferably, the material-picking mechanism is configured to move between the material-picking point and the adhesive point. When at the adhesive point, the material-picking mechanism presses the adhesive side of the cut tape adsorbed thereon against the surface of the object to be pasted.

[0012] Preferably, when the material picking mechanism is at the material picking point, the projection of the cutting path of the cutting mechanism on the tape is located between the first segment and the third segment.

[0013] Preferably, the material handling mechanism includes: The third adsorption head has a third adsorption surface for adsorbing adhesive tape; A multi-axis drive unit is provided, and the third adsorption head is mounted on the execution end of the multi-axis drive unit. The multi-axis drive unit is used to drive the third adsorption head to move between the material pick-up point and the adhesive point.

After being cut, the tape with a pull tab can be freely applied to various workpieces by the operator. Compared to manual operation, which easily leads to contamination and reduced tape adhesion, this device uses a notch in the folding mechanism to directly adsorb and fold the tape. No external objects contact the tape surface during operation, ensuring optimal adhesion. Furthermore, the notch allows only a portion of the tape to be suspended, minimizing sagging and ensuring the first and second adsorption heads of the folding mechanism can accurately move under the suspended tape, improving the stability and efficiency of the folding process. Moreover, during cutting after the tape pull tab is formed, both sides of the cut section are adsorbed and fixed, ensuring stability during the cutting process. Attached Figure Description

Detailed Implementation

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1 to 12 As shown, this utility model embodiment provides a single-sided tape folding and pasting device for folding the tape 1 so that at least part of the adhesive side is folded and pasted together. The folding and pasting device mainly includes an auxiliary fixing mechanism 2 and a folding mechanism 3.

[0023] The auxiliary fixing mechanism 2 has an adsorption plate 21 for supporting the tape 1 and adsorbing the back side (the non-adhesive side) of the tape 1 onto it, and the adsorption plate 21 has a notch 22 formed thereon. The folding mechanism 3 has a first adsorption head 31, a second adsorption head 32, a first adsorption surface 311 on the first adsorption head 31 for adsorbing the tape 1, and a second adsorption surface 321 on the second adsorption head 32 for adsorbing the tape 1; the second adsorption head 32 can rotate relative to the first adsorption head 31 between a first position and a second position, and when the second adsorption head 32 is in the first position, the first adsorption surface 311 and the second adsorption surface 321 are flush (e.g., ...). Figure 1 , Figure 2When the second adsorption head 32 is in the second position, the first adsorption surface 311 and the second adsorption surface 321 face each other, so as to force at least part of the adhesive side of the tape 1 to be folded and bonded together (e.g. Figure 3 ). The folding mechanism 3 is also configured to move between a first position and a second position; when the folding mechanism 3 is at the first position and the second suction head 32 is at the first position (e.g., ... Figure 1 , Figure 2 The first adsorption head 31 and the second adsorption head 32 are at least partially embedded in the notch 22, and at least a portion of the tape 1 in the width direction covers the first adsorption surface 311 and the second adsorption surface 321; when the folding mechanism 3 is located at the second point (e.g. Figures 4 to 6 As the first adsorption head 31 and the second adsorption head 32 disengage from the notch 22, and as the folding mechanism 3 moves from the first point to the second point, the tape 1 moves relative to the auxiliary fixing mechanism 2 along with the folding mechanism 3.

[0024] The specific working process of this folding and pasting device is as follows: The suction plate 21 of the auxiliary fixing mechanism 2 uses negative pressure to adsorb the back of the tape 1, making the tape 1 flat and fixed to the surface of the suction plate 21. At this time, the adhesive side of the tape 1 faces upward (refer to...). Figure 1 , Figure 2 and Figure 10 As shown), and at least a portion of the area in the width direction covers the notch 22 of the adsorption plate 21.

[0025] The folding mechanism 3 is located at the first point (it can be moved from another position to the first point, or it can be initially located at the first point), and the second adsorption head 32 is in the first position (flush with the first adsorption head 31). At this time, the first adsorption head 31 and the second adsorption head 32 are at least partially embedded in the notch 22 of the adsorption plate 21, and the first adsorption surface 311 and the second adsorption surface 321 are in contact with the back of the tape 1 and adsorb the tape 1.

[0026] Then, the adsorption plate 21 releases its adsorption on the back of the tape 1 (the adsorption plate 21 can also be configured in sections, with the portion along the width of the tape 1 and located next to the notch 22 of the adsorption plate 21 designated as the first section, and the remaining portions adsorbing the tape 1 designated as the second section; the first and second sections are controlled independently for adsorption, so the adsorption of the tape 1 by the first section can also be released separately). The second adsorption head 32 rotates around the first adsorption head 31 to the second position, at which point the first adsorption surface 311 and the second adsorption surface 321 change from being flush to facing each other. The area of ​​the tape 1 that is adsorbed folds in half as the second adsorption head 32 rotates, and the adhesive surfaces adhere to form a pull tab for the tape 1 (the folded part is the pull tab, and the unfolded part is the main tape; the pull tab facilitates subsequent tearing or removal of the tape).

[0027] After folding, the folding mechanism 3 moves from the first point to the second point, creating a gap between the auxiliary fixing mechanism 2 and the folding mechanism 3. During this process, the first suction head 31 and the second suction head 32 disengage from the notch 22 of the suction plate 21. The tape 1 moves synchronously with the folding mechanism 3, pulling out a portion of the tape. Some tape remains on the suction plate 21, some is suspended between the auxiliary fixing mechanism 2 and the folding mechanism 3, and some is supported by the folding mechanism 3. At this point, the suction plate 21 re-adheres the tape 1. Workers or an automated cutting mechanism can then cut the tape along the side edge of the notch 22 on the suction plate 21 (the portions on both sides of the cutting point are respectively adsorbed and fixed by the auxiliary fixing mechanism 2 and the folding mechanism 3 for easy cutting), obtaining a section of tape with a pull tab. This cut tape with a pull tab can then be used for subsequent product bonding. All mechanisms return to their original states to form a work cycle. It should be noted that the above working process involves using the folding mechanism 3 to fold the tape 1 in half to form a pull head before moving it to the second position. Alternatively, the tape 1 can be adsorbed by the first adsorption surface 311 and the second adsorption surface 321 before moving it to the second position and then performing the tape 1 folding process.

[0028] This folding and pasting device can produce tape for sealing screw holes in water pumps (such as diaphragm booster pumps for water purifiers). Since water pumps are not pre-installed with compatible bases during testing, the screw holes on the pumps are at risk of water ingress during various performance tests, potentially leading to corrosion and damage. Currently, the common practice is to manually fold the tape to form a pull tab before pasting it onto the screw holes for sealing. The pull tab facilitates subsequent removal of the tape. However, the folding and pasting device of this application, after forming a pull tab, allows workers to directly paste the tape, or it can be used in conjunction with other pasting equipment to automate the process, significantly improving work efficiency and saving labor costs.

[0029] In the tape bonding device and packaging equipment described in patent publication number CN 222808411 U, a conveying component is required to move the target workpiece under the tape, so that the tape is directly adhered to the target workpiece, and the movement of the target workpiece propels the tape forward. This method uses the target workpiece (the workpiece to be taped) and the conveying component together as a driving structure to pull out the tape, and then folds the tape to form a pull head. This method has significant limitations; it is only suitable for regular target workpieces. For irregularly shaped workpieces or small bonding surfaces, it cannot stably drive the tape out. Furthermore, the tape is directly adhered to the target workpiece during the pulling process, making it only suitable for one-time application to specific workpieces, and its effectiveness is poor for other products. It is particularly unsuitable for sealing screw holes in water pump products.

[0030] This application utilizes the self-moving folding mechanism 3 to pull out the tape 1, eliminating the need for a target workpiece. After being cut, the tape with a pull head can be freely attached to various workpieces by the operator. Compared to manual operation, which easily leads to contamination and reduced tape adhesion, this device uses the folding mechanism 3 with an embedded notch 22 to directly adsorb and fold the tape to form a pull head. No external objects contact the tape surface during operation, ensuring adhesiveness. Furthermore, the notch 22 allows the tape 1 to be partially suspended in the width direction, minimizing the problem of the tape 1 drooping. This ensures that the first and second adsorption heads 31 and 32 of the folding mechanism 3 can accurately move under the suspended tape 1, improving the stability and efficiency of the tape folding process. Moreover, when cutting the tape 1 after the pull head is formed, both sides of the cut section are adsorbed and fixed by the first adsorption head 31 and the adsorption plate 21, ensuring the stability of the tape 1 cutting process.

[0031] Reference Figure 3 and Figure 5 As shown, in some practical applications, the auxiliary fixing mechanism 2 is configured to adsorb and position the first segment 11 of the tape 1 carried on the adsorption plate 21 after the folding mechanism 3 moves from the first point to the second point.

[0032] Specifically, components with adsorption functions, such as the adsorption plate 21, the first adsorption head 31, and the second adsorption head 32, belong to existing technology in the pneumatic field: for example, refer to... Figure 4 and Figure 8 As shown, the adsorption plate 21 is hollow inside, with several air holes 211 on its top (serving as the adsorption surface) connecting to its interior. A connector 212 is located at its bottom, connecting to the negative pressure chamber of a negative pressure generator (not shown). An external air source (not shown) is connected to the air inlet of the negative pressure generator. When the tape 1 is placed at the air hole 211 of the adsorption plate 21, a negative pressure is generated by the negative pressure generator, creating a negative pressure inside the adsorption plate 21 to adsorb the tape 1 onto the surface of the adsorption plate 21 with the air holes 211. The adsorption principle of the first adsorption head 31 and the second adsorption head 32 is the same as that of the adsorption plate 21; the specific structure is shown in [reference needed]. Figure 11 As shown, we will not go into too much detail here.

[0033] Based on the aforementioned auxiliary fixing mechanism 2, the folding and pasting device has at least the following two implementation methods.

[0034] Implementation Method 1: Refer to Figure 1 and Figure 4As shown, the folding mechanism 3 is configured such that after the folding mechanism 3 moves from the first point to the second point, the first suction head 31 and the second suction head 32 adsorb and position the second segment 12 of the tape 1; the folding and pasting device also includes a cutting mechanism 4 located between the first segment 11 and the second segment 12, so as to cut the tape 1 at the position between the first segment 11 and the second segment 12 when the first segment 11 and the second segment 12 are respectively adsorbed and positioned by the auxiliary fixing mechanism 2 and the folding mechanism 3.

[0035] After the folding mechanism 3 completes the folding of the tape 1 to form a pull head and moves to the second position, it continuously adsorbs the second segment 12 of the tape 1 (i.e., the part where the pull head of the tape 1 is formed) through the first adsorption surface 311 and the second adsorption surface 321, while the first segment 11 of the tape 1 (the part still located on the adsorption plate 21) is again adsorbed and fixed by the adsorption plate 21. At this time, the tape 1 is in a fixed state at both ends at the cutting position, and the cutting mechanism 4 cuts the tape 1 between the first segment 11 and the second segment 12. The cut tape 1 (the part containing the pull head) is moved away with the folding mechanism 3 for subsequent pasting (the second adsorption head needs to be rotated to the first position to facilitate the removal of the tape with the pull head), and can be directly removed by hand for pasting at the corresponding position on the product; the first segment 11 remains on the adsorption plate 21, waiting for the next cycle.

[0036] Implementation Method Two: Refer to Figure 1 and Figure 5 As shown, the folding and pasting device further includes: a material-picking mechanism 5, configured to move to the material-picking point after the folding mechanism 3 moves from the first point to the second point to adsorb and position the third segment 13 of the tape 1, the material-picking point being located between the first point and the second point; and a cutting mechanism 4, located between the first segment 11 and the third segment 13, to cut the tape 1 at a position between the first segment 11 and the third segment 13, provided that the first segment 11 and the third segment 13 are respectively adsorbed and positioned by the auxiliary fixing mechanism 2 and the material-picking mechanism 5. In some practical applications, the cutting mechanism 4 includes a cutting blade 41 and a first drive unit 42 (generally a linear cylinder); the first drive unit 42 is drively connected to the cutting blade 41 and is used to drive the cutting blade 41 to perform reciprocating linear motion to cut the tape.

[0037] After the folding mechanism 3 folds the tape 1 in half to form a pull head and moves to the second position, the material-picking mechanism 5 moves to the material-picking position (located between the first and second positions). It then uses its own adsorption structure to adsorb the third segment 13 of the tape 1 (the part between the tape pull head and the adsorption plate, i.e., the part suspended between the auxiliary fixing mechanism and the folding mechanism). The first segment 11 of the tape 1 is again adsorbed and fixed by the adsorption plate 21. At this point, the tape 1 is in a fixed state at both ends at the cutting position. The cutting mechanism 4 cuts the tape 1 between the first segment 11 and the third segment 13. The folding mechanism 3 can release the adsorption before or after cutting, allowing the material-picking mechanism 5 to adsorb the resulting tape with the pull head onto it for easy retrieval.

[0038] In some practical applications, based on the above implementation method, the material picking structure is further optimized: the material picking mechanism 5 is constructed to be able to move between the material picking point and the pasting point. When the material picking mechanism 5 is at the pasting point, the material picking mechanism 5 will press the adhesive side of the cut tape 1 adsorbed on it against the surface of the object to be pasted, and perform fully automated pasting, eliminating the manual pasting step.

[0039] Specifically, when the material-taking mechanism 5 is at the material-taking point, the projection of the cutting path of the cutting mechanism 4 onto the tape 1 is located between the first segment 11 and the third segment 13 (e.g., Figure 5 As shown, this is the boundary between the first paragraph 11 and the third paragraph 13. In practical applications, refer to... Figures 5 to 7 As shown, the material handling mechanism 5 includes a third adsorption head 51 and a multi-axis drive unit. The third adsorption head 51 has a third adsorption surface 511 for adsorbing the tape 1 (refer to the working principle of the adsorption plate 21 described above, such as...). Figure 12 The third adsorption head 51 is installed on the execution end of the multi-axis drive unit, which is used to drive the third adsorption head 51 to move between the material picking point and the adhesive point; when the third adsorption head 51 is at the material picking point, the third adsorption surface 511 adsorbs the third segment 13 of the tape 1.

[0040] The multi-axis drive unit includes at least a first linear cylinder 521, and the third suction head 51 is mounted on the actuating end of the first linear cylinder 521 to drive the third suction head 51 to move up and down (see reference). Figure 5(As shown in the direction). When the first linear cylinder 521 runs to its upper limit, the third suction head 51 is located at the material picking point. The multi-axis drive unit also includes a fixedly installed flip cylinder 522, and the first linear cylinder 521 is installed at the execution end of the flip cylinder 522. When the flip cylinder 522 is in the initial position, the third suction surface 511 of the third suction head 51 is horizontally arranged to adhere tightly to the back of the tape 1. When the flip cylinder 522 is in the action position, the third suction surface 511 of the third suction head 51 is vertically arranged to adhere the tape 1 to the object to be adhered. Taking a water pump as an example, when the water pump is placed in the preset position and the flip cylinder 522 is in the action position, the tape 1 is facing the screw hole of the water pump. By running the first linear cylinder 521 again, the tape 1 can be adhered to the screw hole. It should be noted that for some scenarios where it is impossible to adhere, this material picking structure is only used to remove the tape 1 to a safe position so that the staff can remove the tape 1.

[0041] In some practical applications, refer to Figure 2 As shown, the folding mechanism 3 further includes a fixedly mounted second linear cylinder 33 and a folding cylinder 34. The folding cylinder 34 is mounted on the actuating end of the second linear cylinder 33. The first adsorption head 31 is fixedly mounted on the housing of the folding cylinder 34, and the second adsorption head 32 is mounted on the actuating end of the folding cylinder 34. The second linear cylinder 33 is used to drive the folding cylinder 34 to move between a first position and a second position. The second adsorption head 32 is driven by the actuating end of the folding cylinder 34 to realize its rotation relative to the first adsorption head 31 between the first position and the second position.

[0042] In some practical applications, refer to Figure 1 As shown, the folding and pasting device also includes a bracket 6, a fixed wheel 7, and a guide wheel 8. The fixed wheel 7 is fixed to the bracket 6 to allow the roll of adhesive tape 1 to be coaxially sleeved and supported. The guide wheel 8 is rotatably connected to the bracket 6, and its outer circumferential surface is tangential to the adsorption surface of the adsorption plate 21, so that the adhesive tape 1 extends to the adsorption surface of the adsorption plate 21 after being guided by the outer circumferential surface of the guide wheel 8. The auxiliary fixing mechanism 2, the folding mechanism 3, the cutting mechanism 4, and the material picking mechanism 5 are all disposed on the bracket 6. Specifically, the adsorption plate 21 in the auxiliary fixing mechanism is directly fixedly installed on the bracket; the second linear cylinder 33 in the folding mechanism 3 is fixedly installed on the rear side of the bracket, and the folding cylinder is installed at the execution end of the second linear cylinder and located at the front side of the bracket; the first drive unit 42 in the cutting mechanism 4 is fixedly installed on the bracket; the flipping cylinder 522 in the material picking mechanism is fixedly installed on the bracket, and the first linear cylinder 521 is installed at the execution end of the flipping cylinder.

[0043] like Figure 1As shown, the guide wheel 8 is configured as an anti-stick roller, which can prevent the adhesive surface of the tape 1 from decreasing to a certain extent. In the initial state, the roll of tape 1 is coaxially sleeved on the fixed wheel 7, and the free end of the tape 1 is pre-pulled out and passes around the subsequent guide wheel 8. The released tape 1 first contacts the guide wheel 8. Since the outer peripheral surface of the guide wheel 8 is tangential to the adsorption surface of the adsorption plate 21, the tape 1 is turned after passing the outer peripheral surface of the guide wheel 8 to adhere to the surface of the adsorption plate 21.

[0044] In summary, the working principle of this application is as follows: The worker pre-installs the roll of tape 1 onto the fixed wheel 7, and pulls out tape 1, moving it through the guide wheel 8 to the adsorption plate 21 (with the adhesive side of tape 1 facing upwards). The adsorption plate 21 can be used to adsorb the back of tape 1, ensuring that part of tape 1 is suspended above the notch 22. During operation, the first adsorption head 31 and the second adsorption head 32 are flush, and the folding mechanism 3 moves from the second point to the first point (e.g., ...). Figure 1 and Figure 2 As shown), the first adsorption head 31 and the second adsorption head 32 are located inside the notch 22 and below the tape 1 at the notch 22. The first adsorption head 31 and the second adsorption head 32 adsorb the tape 1 through negative pressure, while the adsorption plate 21 releases the adsorption of the tape 1.

[0045] Subsequently, the folding cylinder 34 actuates, and the second adsorption head 32 rotates around the first adsorption head 31 to the second position. At this time, the first adsorption surface 311 and the second adsorption surface 321 change from a flush state to a facing state (e.g., Figure 3 (As shown). The area of ​​tape 1 that is adsorbed is folded as the second adsorption head 32 rotates, and the adhesive surfaces are bonded together to form a pull head for tape 11.

[0046] Then, the second linear cylinder operates, driving the folding cylinder 34, the second suction head 32, and the first suction head 31 to move, so that the folding mechanism 3 moves to the second position (e.g., Figure 5 The first linear cylinder 521 operates and moves the third adsorption head 51 between the adsorption plate 21 and the first adsorption head 31, adsorbing the tape 1 directly above it. The adsorption plate 21 then adsorbs the tape 1 located on it again. The first adsorption head 31 and the second adsorption head 32 release the adsorption on the pull head of the tape 1. At this time, the tape 1 is only adsorbed and fixed by the adsorption plate 21 and the third adsorption head 51.

[0047] Subsequently, the first drive unit 42 drives the cutting blade 41 to descend (as shown in the image). Figure 5 (as shown in the direction), the cutting blade 41 cuts the tape 1, and the cutting position is located between the adsorption plate 21 and the third adsorption head 51 (as shown in the direction). Figure 5 Then, the first linear cylinder 521 of the material handling mechanism 5 drives the cut tape 1 and the pull head to retract (i.e., as shown in the image). Figure 6The rotating cylinder 522 then drives the first linear cylinder 521, the cut tape 1, and the pull head to rotate together. The first linear cylinder 521 is in a horizontal position, and when it operates again, the cut tape 1 and the pull head are pasted onto the designated position of the workpiece (e.g., ...). Figure 7 (As shown in the image) After the tape 1 is pasted onto the workpiece, the third suction head 51 can release the tape 1, thus completing the entire process of making, cutting, and pasting the tape 1 onto the workpiece.
