[0002] In the product assembly process, there are many applications of adhesive tape, such as when attaching epoxy boards or other insulating films, where double-sided tape needs to be applied to specific sides. For mass production, although it is possible to purchase pre-adhesive-backed epoxy boards or insulating films, this method leads to increased material costs.

[0003] Furthermore, while adhesive tape is provided for employees at some assembly line workstations during the tape application process, several drawbacks exist in actual operation. Employees must manually tear off the tape for each product produced, and finding the tape end consumes a significant amount of time. In addition, due to manual operation, the length of the torn tape is inconsistent, which not only affects product quality but also negatively impacts the product's appearance. Utility Model Content

The inner ring fixing mechanism of the colloid is located on the turntable and is used to fix the inner ring of the colloid. The housing has a tape outlet, and a tape separating mechanism is provided on the housing at the tape outlet.

[0008] The controller drives the motor and rotates the turntable, causing the adhesive on the inner ring fixing mechanism to rotate synchronously and be unwound to the tape outlet of the shell. The tape separation mechanism on the shell tears the unwound portion of the adhesive under the action of the controller.

[0009] In the above technical solution, the controller includes a power module and an operation panel, as well as a microcontroller and a drive module powered by the power module. The operation panel is electrically connected to the corresponding connection terminal of the microcontroller, and the microcontroller controls the rotation of the motor through the drive module.

[0010] In the above technical solution, the rotating mechanism also includes an encoder, which is installed at the tail of the motor and connected to the controller. The power output shaft of the motor is connected to the turntable via a coupling.

[0011] In the above technical solution, the turntable is provided with multiple sets of colloid inner ring fixing mechanisms arranged in a circle. Each set of colloid inner ring fixing mechanisms includes a claw, a rotating shaft and a limiting block. The claw is mounted on the turntable through the rotating shaft, and a limiting block is provided on the turntable on one side of the claw, so that the claw is restricted by the limiting block to rotate around the rotating shaft in a local area.

[0012] In the above technical solution, the outer surface of the inverted claw is an arc-shaped surface that can fit against the inner wall of the inner ring of the colloid, and the end of the inverted claw is provided with a claw blade that can be inserted into the inner ring of the colloid.

[0032] The present invention will be further described below with reference to the accompanying drawings and the given embodiments, but it is not limited thereto.

[0033] like Figure 1 , 2 As shown in Figures 3, 4, 5, 6, and 7, an intelligent portable tape tearing device with adjustable tape extension length includes a base plate 1, a housing 2, a controller 3, a rotating mechanism 4, an inner ring fixing mechanism for the adhesive tape 5, and a tape separating mechanism 6.

[0034] The base plate 1 is assembled and connected to the housing 2. The controller 3 and the rotating mechanism 4 are both located on the base plate 1 and inside the housing 2.

[0035] The rotating mechanism 4 includes a turntable 41 and a motor 42. The power output shaft of the motor 42 is connected to the turntable 41 for transmission, and the controller 3 is used to control the operation of the motor 42. The inner ring fixing mechanism 5 is provided on the turntable 41 to fix the inner ring of the colloid. The housing 2 is provided with a tape outlet, and a tape separating mechanism 6 is provided on the housing 2 at the tape outlet. The diameter of the turntable 41 is larger than the inner diameter of the inner ring of the colloid.

[0036] The controller 3 drives the motor 42 and drives the turntable 41 to rotate, so that the adhesive on the inner ring fixing mechanism 5 rotates synchronously and is unwound to the tape outlet of the housing 2. The tape separation mechanism 6 on the housing 2 tears the unwound portion of the adhesive under the action of the controller 3.

[0037] This invention can be used in conjunction with adhesives that have paper rings inside the adhesive 7. The type of adhesive is not limited and can be double-sided tape, transparent tape, or foam adhesive, etc.

[0038] Furthermore, such as Figure 1 , 2As shown, to enhance automation, the controller 3 includes a power module 31 and an operation panel 32, as well as a microcontroller 33 powered by the power module 31 and a drive module 34. The operation panel 32 is electrically connected to the corresponding connection terminal of the microcontroller 33, and the microcontroller 33 controls the rotation of the motor 42 through the drive module 34. The operation panel 32 is located on the side of the lower shell 22. The operation panel 32 has buttons and a display screen connected to the microcontroller 33. The microcontroller 33 receives input from the buttons on the operation panel 32 and can also control the content displayed on the operation panel. The microcontroller 33 is preferably an STM32 microcontroller, but it is not limited to this and other models of microcontrollers can also be used.

[0039] Furthermore, such as Figure 3 As shown, to more accurately control the length of each unwinding of the colloid, a motor and encoder work together. The rotating mechanism 4 also includes an encoder 43, which is mounted at the tail of the motor 42 and connected to the controller 3. The power output shaft of the motor 42 is connected to the turntable 41 via a coupling. The controller 3 receives data from the encoder 43 to determine the rotation angle of the motor.

[0040] Furthermore, such as Figure 3 , 4 As shown in Figure 5, in order to fix the inner ring of the colloid, the turntable 41 is provided with multiple sets of colloid inner ring fixing mechanisms 5 arranged in a circle. Each set of colloid inner ring fixing mechanisms 5 includes a claw 51, a rotating shaft and a limiting block 52. The claw 51 is mounted on the turntable 41 through the rotating shaft, and a limiting block 52 is provided on the turntable 41 and located on one side of the claw 51, so that the claw 51 is restricted by the limiting block 52 to rotate around the rotating shaft in a local area.

[0041] Furthermore, such as Figure 4 , 5 As shown, to further stabilize and fix the inner ring of the colloid, the outer surface of the barbed claw 51 is an arc-shaped surface that can fit against the inner wall of the colloid inner ring, and the end of the barbed claw 51 is provided with a claw blade that can be inserted into the colloid inner ring. The barbed claw 51 can retract or extend its claw blade by rotating itself. When the barbed claw is retracted, the outer diameter of the multiple colloid inner ring fixing mechanisms that form a circle is smaller than the inner diameter of the colloid inner ring. When the barbed claw is extended, the outer diameter of the multiple colloid inner ring fixing mechanisms is larger than the inner diameter of the colloid inner ring. The colloid inner ring is fitted around the outer circumference of the multiple barbed claws 51, and at the same time, the claw blades of the barbed claws 51 are inserted into the colloid inner ring to fix it.

[0042] Furthermore, such as Figure 6 , 7As shown, in order to achieve automatic tape tearing, the tape separation mechanism 6 includes a dividing unit for cutting the adhesive and a separation unit for separating the cut adhesive. The dividing unit is provided on one side of the tape outlet of the housing 2, and the separation unit is provided on the other side of the tape outlet.

[0043] Furthermore, such as Figure 6 , 7 As shown, in order to achieve rapid cutting of colloid, the segmentation unit includes a bracket 61, a micro switch 62, and a blade 63. The bracket 61 is mounted on the housing 2. The micro switch 62 is fixed on the bracket 61 through a mounting hole and is electrically connected to the controller 3. The blade 63 is slidably engaged with the bracket 61, and the blade 63 can abut against or separate from the micro switch 62.

[0044] Furthermore, such as Figure 6 , 7 As shown, to further optimize the structure and make it more rational, the blade 63 is slidably engaged with the track groove of the bracket 61 via a female rivet, and the cutting edge of the blade 63 faces outward to tear the adhesive. The inner part of the blade 63 has a bent edge to increase the contact area with the micro switch 62. When the blade 63 slides inward along the track groove of the bracket 61, it will touch the micro switch, and the microcontroller 33 of the controller 3 can receive the signal emitted by the micro switch.

[0045] Furthermore, such as Figure 6 As shown, in order to ensure that the separating plate always adheres tightly to the colloid and prevents it from moving during the cutting process and affecting the cutting length, the separating unit includes a separating plate 64 and a spring hinge 65. The separating plate 64 is connected to the housing 2 through the spring hinge 65, and the spring hinge 65 is used to keep the separating plate 64 always adhered to the colloid.

[0046] Furthermore, the separating sheet 64 of this invention is a metal substrate, and its outer surface is covered with an anti-sticking film. The separating sheet 64 is a 3A21 aluminum plate or a steel plate, and the anti-sticking film is a non-sticky material such as kraft paper or plastic film.

[0047] Furthermore, such as Figure 1 As shown, in order to make the structure more reasonable and realize the rapid assembly of the upper cover and the lower shell, the shell 2 includes an upper cover 21 and a lower shell 22. The lower shell 22 is fixed on the base plate 1 and covers the outer periphery of the controller 3. The bottom of the upper cover 21 is inserted into the lower shell 22. The coupling shaft end provided on the power output shaft of the motor 42 passes through the lower shell 22 and is rigidly connected to the turntable 41 on the upper end face of the lower shell 22. The tape separation mechanism 6 is provided at the tape outlet provided on the upper cover 21.

[0048] This utility model further describes the usage process:

[0049] Colloid mounting:

[0050] Due to the action of the spring hinge 65, the separation piece 64 will extend into the inside of the turntable 41 when it is not under force. Therefore, during the installation of the colloid, the separation piece 64 needs to be moved to the outside of the turntable 41.

[0051] Since the outer diameter of the multiple inner ring fixing mechanisms of the multiple inverted claws 51 is smaller than the inner diameter of the inner ring of the colloid when the multiple inverted claws 51 retract, the colloid can be placed on the inner ring fixing mechanism of the colloid, so that the inverted claws contact the colloid paper ring of the colloid 7.

[0052] Rotating the colloid counterclockwise will cause the inverted claw 51 to rotate around the axis until it hits the limit block 52. Continuing to rotate will cause the claw edge of the inverted claw 51 to embed into the inner ring of the colloid, thereby fixing the colloid on the turntable 41.

[0053] Lead the head of the colloid out from the colloid outlet position of the top cover 21, and then release the separation plate 64. At this time, the separation plate 64 will be pressed against the junction of the colloid protrusion and the colloid body by the action of the spring hinge 65.

[0054] The process of tearing the tape:

[0055] Once the tape extends a certain length, it can be pulled in the opposite direction of extension. The tension in the tape acts on the blade 63. However, since the blade 63 can slide, it will slide inward until it encounters the microswitch 62. At this point, the microswitch 62 closes, sending a signal to the microcontroller 33 of the controller 3, indicating that the blade is in position and cutting the tape. When the microswitch 62 is fully closed, the blade is locked and cannot slide. If the tape is pulled further, it will be cut by the blade.

[0056] After the tape is cut, the blade 63 is no longer under force, and the spring mechanism inside the microswitch 62 will push the blade 63 open with its contacts. Since the contacts of the microswitch 62 are no longer closed, the microcontroller 33 can no longer receive signals from the microswitch. Combined with the fact that the microswitch first closes and then opens, it can be determined that one tape-tearing operation has been completed. Because there is an anti-stick film at the tape exit point of the top cover, the tape will not stick to the machine after it is torn.

[0057] The configuration mode of this utility model is as follows:

[0058] First, switch the machine to the settings mode via the operation panel 32.

[0059] In the setting mode, the motor 42 in the rotating mechanism 4 is not powered but can rotate freely. The operator first presses the start button on the operation panel 32 and then pulls out the adhesive. During the pulling process, the motor 42 will rotate accordingly, and the encoder 43 at the bottom of the motor 42 will calculate the rotation angle of the adhesive and input the data signal to the microcontroller 33 of the controller 3. After the operator pulls out the adhesive to a certain length, they press the stop button on the operation panel 32. The microcontroller 33 of the controller 3 records the rotation angle. When the rotation angle is the same, the length of the torn tape is also approximately the same.

[0060] The manual mode setting of this utility model is as follows:

[0061] First, switch the machine to manual mode via the operation panel 32. In manual mode, initially, the motor 42 is de-energized and can rotate freely. When the operator pulls the adhesive, it drives the motor 42 to rotate. The encoder 43 at the bottom of the motor 42 calculates the rotation angle and inputs the data signal to the microcontroller 33 of the controller 3. When the microcontroller 33 of the controller 3 detects that the rotation angle of the encoder 43 during the pulling process is the same as the rotation angle recorded in the setting mode, it controls the motor 42 to be energized and stationary. At this time, the operator cannot continue to pull the adhesive, so they pull the tape in the opposite direction of the extension direction until the microswitch 62 closes and the tape breaks. After the tape breaks, the microswitch 62 opens, and the microcontroller 33 of the controller 3 can determine that one tape tearing action has been completed, so it returns the motor to a state of de-energization and free rotation, waiting for the next operation.

[0062] Automatic mode setting of this utility model:

[0063] First, switch the machine to automatic mode via the operation panel 32. In automatic mode, the motor 42 is always powered. Initially, the motor 42 rotates automatically, and the adhesive follows the turntable 41. At this time, the extended portion of the adhesive extends outward along the separating plate 64 and separates from the adhesive body. During this process, the encoder 43 at the bottom of the motor 42 calculates the rotation angle and inputs the data signal to the microcontroller 33 of the controller 3. When the microcontroller 33 of the controller 3 detects that the rotation angle of the encoder 43 is the same as the rotation angle recorded in the setting mode during the automatic rotation of the motor 42, the motor 42 stops rotating and becomes stationary. At this time, the adhesive tape has extended to the specified length as required. When the operator pulls the adhesive tape in the opposite direction of the extension direction until the micro switch closes, the adhesive tape breaks. After the adhesive tape breaks, the micro switch 62 opens, and the microcontroller 33 of the controller 3 can determine that one tape tearing action has been completed. Therefore, the motor resumes automatic rotation until the adhesive tape extends to the specified length again, at which point the motor stops rotating and becomes stationary, waiting for the next operation.

[0064] This invention, through the synergistic action of a motor and encoder, not only precisely controls the extension length of the adhesive tape each time, effectively ensuring product quality, but also significantly improves the efficiency of the adhesive application process. Furthermore, this invention is not only simple in structure and easy to operate, but also has low production costs, making it feasible for large-scale production applications.

[0065] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
