Description

Technical Field

[0001] This utility model relates to the field of adhesive paper roll production technology, and in particular to a tooling fixture for adhesive paper roll production. Background Technology

[0002] Adhesive paper rolls are indispensable high-precision cleaning consumables in fields such as electronic manufacturing, PCB production, and optical device processing. Their core function is to remove micron-sized dust and particulate contaminants through high-density adhesive on the surface.

[0003] Existing technology CN219882299U discloses a tooling fixture for producing adhesive paper rolls. A processing table is fixedly connected to the top ends of two electric telescopic rods, and a moving block is fixedly connected to the top end of a slider. A linkage plate is rotatably connected to one side of the moving block via a bearing, and a clamping rod is fixedly connected to one side of the linkage plate. When the adhesive paper roll needs to be clamped, the operator only needs to manually place the paper roll onto the outside of the clamping sleeve. The output shaft of a second motor drives a spur gear to rotate, and a serrated plate drives a push plate to move towards the moving block. The clamping sleeve fixes and positions the adhesive paper roll. Only one motor needs to be started for automatic clamping of the adhesive paper roll, freeing the operator's hands, reducing the number of steps involved in clamping the adhesive paper roll, and improving the working efficiency of the tooling fixture for producing adhesive paper rolls.

[0004] However, the above-mentioned fixture has the following problems: Since the existing fixture cannot be height adjusted, when clamping a thick sticky paper roll, the sticky paper roll will contact the processing table after reaching a certain thickness and cannot be rolled up further. In addition, the above-mentioned fixture cannot adjust the clamping force of the sticky paper roll according to the size of the inner wall of the sticky paper roll. Summary of the Invention

[0005] This utility model overcomes the shortcomings of the prior art and provides a tooling fixture for producing adhesive paper rolls.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a tooling fixture for producing adhesive paper rolls, comprising: a plurality of connecting frames, a plurality of rotating components disposed on the plurality of connecting frames, and a plurality of supporting components connected to the plurality of rotating components;

[0007] The rotating assembly includes: a first motor disposed on the connecting frame, and a first lead screw connected to the bottom of the first motor;

[0008] The support assembly includes: a connecting seat sleeved on the first lead screw, and a second motor disposed on the connecting seat;

[0009] The output end of the second motor is connected to a coupling, the coupling is connected to a rotating shaft, the rotating shaft is connected to a rotary bearing, one end of the rotary bearing is fixed to a support base, a third motor is mounted on the support base, the third motor is connected to an electric push rod, and a clamping assembly is fixed to the end of the electric push rod.

[0010] In a preferred embodiment of the present invention, the clamping assembly includes a plurality of first connecting blocks fixed to the end of the electric push rod, and a plurality of clamping rods connected to the first connecting blocks; a support rod is sleeved on the electric push rod, and one end of the support rod is fixed to the third motor.

[0011] In a preferred embodiment of the present invention, a plurality of second connecting blocks are fixed to the end of the support rod, and a plurality of clamping rods are connected to the plurality of second connecting blocks, and the plurality of clamping rods are connected by hinges.

[0012] In a preferred embodiment of this utility model, a plurality of pressure sensors are provided at the connection points of the plurality of clamping rods.

[0013] In a preferred embodiment of this utility model, the first lead screw is located inside the connecting frame, and an electric telescopic rod is fixed on the outer surface of the connecting frame.

[0014] In a preferred embodiment of this utility model, the other end of the electric telescopic rod is connected to a fourth motor.

[0015] In a preferred embodiment of the present invention, the fourth motor is mounted on a base plate, and a slide rail is provided on the base plate.

[0016] In a preferred embodiment of this utility model, a slider is provided at the bottom of the connecting frame, and the slider is connected to the slide rail.

[0017] In a preferred embodiment of this utility model, the electric push rod and the support rod are coaxially sleeved.

[0018] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0019] In this invention, to meet the requirements of paper rolls of different thicknesses, a first motor is started, and the output shaft drives the first lead screw to rotate. Through the threaded transmission relationship between the first lead screw and the connecting seat, the rotational motion of the motor is converted into the linear motion of the connecting seat along the lead screw axis. As the first lead screw rotates, the connecting seat drives the entire support assembly to move along the lead screw axis, realizing the adjustability of the height of the support assembly, thereby adjusting the height of the adhesive paper roll.

[0020] In this invention, when it is necessary to adjust the lateral position of the fixture on the worktable, the fourth motor is started to drive the electric telescopic rod to extend and retract, so that the slider at the bottom of the connecting frame slides left and right along the slide rail, thereby driving the entire fixture device to move laterally.

[0021] In this invention, when the clamping rod contacts the inner wall of the adhesive paper roll and gradually applies clamping force, the pressure sensor at the connection of the clamping rod monitors the magnitude of the clamping force in real time and converts the pressure signal into an electrical signal, which is then transmitted to the control system. The control system has a preset appropriate clamping force range. When the clamping force fed back by the pressure sensor reaches or approaches the preset value, the control system will issue a command to control the third motor to stop driving the electric push rod to extend, thereby stopping the clamping action and ensuring that the clamping force is maintained in a stable and appropriate state.

[0022] In this invention, the electric push rod extends, and the clamping rod approaches the inner wall of the paper roll under the action of the pushing force, adjusting its angle as allowed by the hinge until the paper roll is firmly clamped; when the electric push rod retracts, the clamping rod releases accordingly. When the electric push rod extends, the clamping assembly approaches the inner wall of the dust-adhesive paper roll under the push of the electric push rod, and the clamping rod gradually inserts into the inner wall of the paper roll. Under the connection of the hinge, several clamping rods can automatically adjust the clamping angle according to the shape of the inner wall of the paper roll, ultimately firmly clamping the dust-adhesive paper roll; when it is necessary to release, the electric push rod retracts, and the clamping assembly moves away from the paper roll.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] like Figures 1-3 As shown, a tooling fixture for producing adhesive paper rolls includes: several connecting frames 1, several rotating components disposed on the several connecting frames 1, and several supporting components connected to the several rotating components.

[0030] In this invention, the rotating assembly includes: a first motor 2 mounted on the connecting frame 1, and a first lead screw 3 connected to the bottom of the first motor 2; the supporting assembly includes: a connecting seat 4 sleeved on the first lead screw 3, and a second motor 5 mounted on the connecting seat 4. The first motor 2 serves as the power source for the rotating assembly. When the height of the adhesive paper roll needs to be adjusted, the first motor 2 starts, and its output shaft drives the first lead screw 3 to rotate. The rotation of the first lead screw 3 provides precise power output for the entire height adjustment process. Through the threaded transmission relationship between the first lead screw 3 and the connecting seat 4, the rotational motion of the motor is converted into linear motion of the connecting seat 4 along the lead screw axis. As the first lead screw 3 rotates, the connecting seat 4 drives the entire supporting assembly to move along the lead screw axis, realizing the adjustability of the height of the supporting assembly. At the same time, the connecting seat 4 also provides a mounting base for the second motor 5, ensuring that the second motor 5 can work normally in a stable position, providing a stable support platform for subsequent rotation and clamping actions.

[0031] In this invention, the output end of the second motor 5 is connected to a coupling 6. The second motor 5 is mounted on a connecting seat 4. When the adhesive paper roll needs to be wound or unwound, the second motor 5 starts, and its output end drives the coupling 6 to rotate. The coupling 6 connects the output end of the second motor 5 and the rotating shaft 7. When the second motor 5 rotates, the coupling 6 rotates accordingly, transmitting the rotational power of the motor to the rotating shaft 7. The rotating shaft 7 is connected to a rotating rod 8, and a support seat 9 is fixed to one end of the rotating rod 8. When the rotating shaft 7 rotates, the rotating rod 8 drives the support seat 9 to rotate together. The support seat 9 rotates with the rotating rod 8, and at the same time provides a mounting platform for the third motor 10. The third motor 10 is mounted on the support seat 9. When the adhesive paper roll needs to be clamped, the third motor 10 starts, driving the electric push rod 11 to extend or retract.

[0032] In this invention, a clamping assembly is fixed to the end of the electric push rod 11. The clamping assembly includes several first connecting blocks 12 fixed to the end of the electric push rod 11, several clamping rods 13 connected to the first connecting blocks 12, and a support rod 14 sleeved on the electric push rod 11. One end of the support rod 14 is fixed to the third motor 10. The support rod 14 supports the electric push rod 11, increases the structural stability of the entire clamping assembly, and prevents the electric push rod 11 from bending or shaking during extension and retraction. It also assists the clamping rods 13 in performing stable clamping actions, ensuring a uniform distribution of clamping force. The first connecting blocks 12 are fixed to the end of the electric push rod 11 and connected to the clamping rods 13. The second connecting block 15 is fixed to the end of the support rod 14 and also connected to the clamping rods 13. When the clamping assembly operates, the portions of the clamping rods 13 connected to the first connecting blocks 12 and the second connecting blocks 15 move in coordination to achieve the opening and closing of the clamping rods 13. The clamping rods 13 are connected to the first connecting block 12 and the second connecting block 15 respectively, and are connected by hinges 16. When the electric push rod 11 extends, the clamping rods 13 move closer to the inner wall of the paper roll under the action of the pushing force, and adjust the angle as allowed by the movement of the hinges 16, until the paper roll is firmly clamped; when the electric push rod 11 retracts, the clamping rods 13 are released accordingly. When the electric push rod 11 extends, the clamping assembly moves closer to the inner wall of the dust-sticking paper roll under the push of the electric push rod 11, and the clamping rods 13 gradually insert into the inner wall of the paper roll. Under the connection of the hinges 16, the clamping rods 13 can automatically adjust the clamping angle according to the shape of the inner wall of the paper roll, and finally firmly clamp the dust-sticking paper roll; when it is necessary to release, the electric push rod 11 retracts, and the clamping assembly moves away from the paper roll.

[0033] In this invention, several pressure sensors 17 are provided at the connection points of several clamping rods 13. During the clamping process of the clamping assembly clamping the adhesive paper roll, when the clamping rods 13 contact the inner wall of the adhesive paper roll and gradually apply clamping force, the pressure sensors 17 at the connection points of the clamping rods 13 monitor the magnitude of the clamping force in real time and convert the pressure signal into an electrical signal, which is transmitted to the control system. The control system has a suitable clamping force range preset. When the clamping force fed back by the pressure sensor 17 reaches or approaches the preset value, the control system will issue a command to control the third motor 10 to stop driving the electric push rod 11 to extend, thereby stopping the clamping action and ensuring that the clamping force is maintained in a stable and appropriate state.

[0034] In this invention, the first lead screw 3 is located inside the connecting frame 1, and an electric telescopic rod 18 is fixed to the outer surface of the connecting frame 1. The other end of the electric telescopic rod 18 is connected to a fourth motor 19, which is mounted on a base plate 20. A slide rail 21 is mounted on the base plate 20, and a slider 22 is mounted at the bottom of the connecting frame 1, connected to the slide rail 21. When it is necessary to adjust the lateral position of the fixture on the worktable, the fourth motor 19 is activated, causing the electric telescopic rod 18 to extend or retract, causing the slider 22 at the bottom of the connecting frame 1 to slide left and right along the slide rail 21, thereby moving the entire fixture device laterally.

[0035] In use, the fourth motor 19 is started, driving the electric telescopic rod 18 to extend and retract, causing the slider 22 at the bottom of the connecting frame 1 to slide left and right along the slide rail 21, moving the entire clamping device laterally to a suitable position for the operator to place the adhesive paper roll. Depending on the thickness of the adhesive paper roll, the first motor 2 is started, its output shaft driving the first lead screw 3 to rotate. As the first lead screw 3 rotates, the connecting seat 4 drives the entire support assembly to move along the lead screw axis, adjusting the height of the clamp so that the clamping assembly is near the clamping position of the adhesive paper roll. The third motor 10 is started, driving the electric push rod 11 to extend, pushing the clamping assembly closer to the inner wall of the adhesive paper roll. During the extension of the electric push rod 11, the clamping rod 13 gradually inserts into the inner wall of the paper roll. When the clamping rod 13 contacts the inner wall of the adhesive paper roll and gradually applies clamping force, the pressure sensor 17 at the connection of the clamping rod 13 monitors the magnitude of the clamping force in real time and converts the pressure signal into an electrical signal, transmitting it to the control system. The control system has a preset clamping force range. When the clamping force fed back by the pressure sensor 17 reaches or approaches the preset value, the control system issues a command to stop the third motor 10 from driving the electric push rod 11 to extend, thereby stopping the clamping action and ensuring that the clamping force is maintained in a stable and appropriate state. The second motor 5 is started, and its output end drives the coupling 6 to rotate. The coupling 6 transmits the rotational power to the rotating shaft 7. The rotating shaft 7 drives the rotating rod 8 to rotate, and the rotating rod 8 in turn drives the support base 9 to rotate. When the support base 9 rotates, it drives the third motor 10, the electric push rod 11, the clamping assembly, and the adhesive paper roll to rotate together, realizing the winding operation of the adhesive paper roll. During the winding process, the speed of the second motor 5 can be adjusted appropriately according to the production process requirements to control the winding speed. At the same time, the winding situation of the adhesive paper roll is observed. When the winding operation is completed, the third motor 10 is started, driving the electric push rod 11 to retract. The clamping assembly then moves away from the adhesive paper roll, and the clamping rod 13 releases the paper roll. The wound adhesive paper roll can be removed from the clamp as needed. If a new adhesive paper roll is needed, repeat the clamping and winding steps. Once the production task is completed, proceed to the equipment's finishing stage.

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.
