Description

Technical Field

[0001] This invention belongs to the field of injection molding processing technology, specifically a double-sided adhesive positioning and bonding fixture for injection molded parts with pre-positioning function. Background Technology

[0002] Injection molded parts refer to all kinds of injection molded products produced by injection molding machines. They are mainly made of materials such as polyethylene or polypropylene and various organic solvents are added. Injection molded parts are mainly used for various packaging, parts, etc., and their uses are very wide. Especially in the production process of mobile phones and computers, injection molded parts are often required for installation and assembly.

[0003] Currently, after some injection molded parts are manufactured, double-sided tape is often applied to their surface to facilitate subsequent assembly. However, the application of double-sided tape to injection molded parts is mostly done manually, that is, a person holds the injection molded part or the double-sided tape in their hand and then sticks the two together.

[0004] However, the quality of double-sided tape application by hand currently relies heavily on workers' experience, resulting in inconsistent quality of the double-sided tape applied to injection molded parts, which affects the subsequent assembly effect. To address this, the present invention provides a double-sided tape positioning and bonding fixture for injection molded parts with a pre-positioning function. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: A double-sided adhesive positioning and bonding fixture for injection molded parts with a pre-positioning function, comprising an X-axis translation module, a Y-axis translation module, and a Z-axis translation module. The Y-axis translation module is mounted above the X-axis translation module. The Z-axis translation module is mounted at the end of the X-axis translation module and located above the Y-axis translation module. A mounting bracket is fixed to the Z-axis translation module on the side near the Y-axis translation module and above the Y-axis translation module. A bonding component is fixed to the bottom surface of the mounting bracket. The bonding component is used to adhere the double-sided adhesive. The bonding component is located near the Z-axis translation module. A connecting frame is provided on one side of the assembly. A placement frame is fixed to the side of the connecting frame near the Y-axis translation module. The placement frame includes a pair of limiting discs and a rotating shaft. The rotating shaft is rotatably connected to the connecting frame, and the limiting discs are engaged with the rotating shaft. A sliding block is slidably connected to the side of the connecting frame near the bonding component. A placement plate is mounted on the side of the sliding block near the bonding component. Multiple vent pipes are installed at the bottom of the placement plate. A lead screw is threadedly connected to the outside of the sliding block, and a drive motor is installed at the bottom of the lead screw. A breathable pad is fixed to the surface of the placement plate. A limiting component is provided below the bonding component, and the limiting component is mounted on the Y-axis. On the top surface of the translation module, the limiting component is used to limit the injection molded part. During operation, the injection molded part to be bonded with double-sided adhesive is first placed inside the limiting component for pre-positioning. Then, the positions of the X-axis, Y-axis, and Z-axis translation modules are adjusted sequentially to transport the injection molded part below the bonding component. The coordinated use of the X-axis, Y-axis, and Z-axis translation modules achieves precise positioning of the injection molded part. After positioning, the drive motor connected to the sliding block is activated, causing the sliding block to slide. This sliding movement of the sliding block drives the placement plate to move, placing... The placement plate first moves to the vicinity of the placement rack. Then, through the cooperation of the internal air pipe and the air pad, a negative pressure is formed on the surface of the placement plate, thereby adsorbing the double-sided adhesive. Subsequently, the sliding block slides again, causing the placement plate to move below the bonding component. At this time, the negative pressure entering the placement plate changes to air blowing, thereby pushing the double-sided adhesive adsorbed on its surface to the bottom surface of the bonding component, where it is adsorbed by the bonding component. Then, the sliding block resets, and the Z-axis translation module descends, causing the bonding component to descend, so that the bonding component is in contact with the surface of the injection molded part, thus adhering the double-sided adhesive to the injection molded part, thereby completing the automatic double-sided adhesive application operation on the injection molded part.

[0007] Preferably, the limiting component includes a limiting frame, and multiple locking posts are slidably connected inside the limiting frame. The locking posts are hollow bosses, and multiple air inlets are provided inside the limiting frame and below the locking posts. During operation, after the injection molded part is placed inside the limiting component, air can be injected into the limiting frame through the air inlets. The inflated locking posts will rise under the air pressure, and the raised locking posts will limit the injection molded part around its perimeter. This allows the device to accommodate injection molded parts of different shapes and types, improving the applicability of the equipment.

[0008] Preferably, a photoelectric sensor is provided below the locking post, and a light-transmitting plate is fixed inside the locking post and directly above the photoelectric sensor. During operation, after the injection molded part is placed inside the limiting assembly, the photoelectric sensor will detect the light on its top through the light-transmitting plate. The photoelectric sensor blocked by the injection molded part will receive a signal. By setting multiple photoelectric sensors, the edge of the injection molded part can be effectively determined, thereby controlling the inflation position of the locking post, so that the locking post below the injection molded part will not be inflated and pushed up. In addition, this method can determine the exact position of the injection molded part installed inside the limiting assembly, which is convenient for subsequent precise positioning.

[0009] Preferably, the snap-fit ​​post has multiple rubber bladders fixed inside, and an electronic valve is connected through the side of each rubber bladder near the center of the snap-fit ​​post. During operation, after the snap-fit ​​post is fully lifted, the electronic valve is opened in a controlled manner, allowing some gas to fill the interior of the rubber bladder, causing it to expand. The expanded rubber bladder further covers the edge of the injection molded part, improving the stability of the installation. After the bonding is completed, the electronic valve needs to be activated to release the air pressure inside the rubber bladder.

[0010] Preferably, the bonding assembly includes an adsorption plate with multiple air inlet pipes installed at the top and a sponge pad fixed to the bottom. During operation, when the placement plate lifts the double-sided adhesive to the bottom of the bonding assembly, the air inlet pipes at the top of the adsorption plate are connected, thereby generating negative pressure to adsorb the lifted double-sided adhesive. The sponge pad can disperse the pressure of the negative pressure, achieving a uniform pressure effect, which facilitates the subsequent application of the double-sided adhesive.

[0011] Preferably, both ends of the adsorption plate are rotatably connected to a pair of rotating arms via torsion springs. The end of each rotating arm away from the adsorption plate is rotatably connected to an extension rod via a torsion spring. An auxiliary shaft is rotatably connected between the ends of the pair of extension rods away from the rotating arms. A drive motor is installed on the outside of each pair of rotating arms near the Y-axis translation module. During operation, after the double-sided adhesive is applied, the Y-axis translation module moves the adsorption plate up one distance. Then, the drive motor is started to drive the rotating arms to rotate. The rotation of the rotating arms drives the extension rods to rotate. During the rotation of the extension rods, the auxiliary shaft will roll back and forth on the applied double-sided adhesive, thereby squeezing the applied double-sided adhesive and improving the reliability of the double-sided adhesive application.

[0012] Preferably, a protective frame is fixed to the side of the placement rack near the bonding component. The protective frame is fixedly connected to the connecting frame. A telescopic frame is fixed to the top of the protective frame, and a cutter is fixed to the bottom of the telescopic frame. During operation, when the double-sided tape is pulled out from inside the placement rack, it will be driven by the placement plate to pass through the cutter. After the placement plate moves into position, the telescopic frame starts to drive the cutter to cut the double-sided tape, thereby achieving the effect of automatically cutting the double-sided tape.

[0013] Preferably, a support frame is provided below the cutter, and a slot adapted to the cutter is opened on the top surface of the support frame. A whetstone is fixed on the inner surface of the slot. During operation, as the telescopic frame moves the cutter downward to cut the double-sided tape, the cutter will come into contact with the support frame. During this process, the whetstone inside the slot will polish the surface of the cutter to ensure the sharpness of the cutter, thereby ensuring that the cutter can successfully cut the double-sided tape.

[0014] Preferably, a pair of support shafts are rotatably connected inside the protective frame and between the telescopic frame and the placement frame. During operation, before installing the double-sided tape, a portion of the double-sided tape needs to be pre-reserved to pass through the pair of support shafts. The support shafts can support the double-sided tape, making it easier for the placement plate to adhere to both sides.

[0015] Preferably, multiple piercing heads are fixed to the outside of the upper support shaft, and the piercing heads are conical. During operation, as the double-sided tape passes through the support shaft, the piercing heads on the outside will pierce the centrifugal paper on the surface of the double-sided tape and pick out part of the centrifugal paper during rotation, thereby facilitating the subsequent tearing of the double-sided tape.

[0016] Preferably, a beveled block is fixedly connected to one end of the placement plate near the sliding block, a beveled push block is slidably connected to the top surface of the beveled block, a toggle lever is fixed to the side of the beveled push block away from the placement frame, and a telescopic rod is fixedly connected to the bottom end of the beveled block. A return spring is provided on the outside of the telescopic rod. During operation, when a longer piece of double-sided tape needs to be pasted and the length of the adsorption plate is insufficient, the extension rod can be lowered by rotating the rotating arm after the placement plate has driven the double-sided tape to its position. Since the double-sided tape has a certain strength, during the movement of the extension rod, it will drive the auxiliary shaft to move past the double-sided tape and lift it up. During this process, the extension rod will contact the toggle lever and push the beveled push block to slide. The sliding of the beveled push block will cause the beveled block to compress the return spring and move. The movement of the beveled block will drive the placement plate to move, causing the placement plate to separate from the double-sided tape. At this time, the bonding component can properly adsorb the double-sided tape. At the same time, the auxiliary shaft can also lift the excessively long double-sided tape, thereby achieving the effect of adapting to the pasting of double-sided tape of different lengths.

[0017] Preferably, multiple air blowers are fixed to both sides of the placement plate. During operation, the air blowers allow air to be introduced into the air blowers when the double-sided tape is too long, so that the airflow can blow the double-sided tape up, making it easier for the auxiliary shaft to support it. It should be noted that after one end of the auxiliary shaft is lifted, the placement plate moves to the end of the bonding component close to the placement frame, so that the air blowers blow air again, making it easier for the auxiliary shaft to lift the double-sided tape.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The present invention provides a double-sided adhesive positioning and bonding fixture for injection molded parts with a pre-positioning function. The pre-positioning component pre-positions the injection molded part, and then the positions of the X-axis translation module, Y-axis translation module and Z-axis translation module are adjusted in sequence so that the injection molded part can be transported to the underside of the bonding component, thereby achieving the effect of pre-positioning and precise positioning of the injection molded part.

[0020] 2. The double-sided adhesive positioning and bonding fixture for injection molded parts with pre-positioning function described in this invention allows air to be injected into the limiting frame through the air inlet after the injection molded part is placed inside the limiting component. The inflated locking pins will rise under the action of air pressure, and the rising locking pins will limit the injection molded part around its perimeter. This can adapt to injection molded parts of different shapes and types, thus improving the applicability of the equipment. Attached Figure Description

Detailed Implementation

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] Example 1

[0032] like Figure 1 , Figure 2 , Figure 7As shown in the embodiment of the present invention, a double-sided adhesive positioning and bonding fixture for injection molded parts with pre-positioning function includes an X-axis translation module 1, a Y-axis translation module 2, and a Z-axis translation module 3. The X-axis translation module 1, Y-axis translation module 2, and Z-axis translation module 3 are all existing technologies and can be combinations of a drive motor, a lead screw, and a slider, which will not be elaborated further here. The Y-axis translation module 2 is mounted above the X-axis translation module 1, and the Z-axis translation module 3 is mounted at the end of the X-axis translation module 1 and above the Y-axis translation module 2. A mounting bracket 5 is fixed to the side of the Z-axis translation module 3 near and above the Y-axis translation module 2. A bonding component 6 is fixed to the bottom surface of the mounting bracket 5. The bonding component 6 is used to adhere the double-sided adhesive. A connecting bracket 7 is provided on the side of the bonding component 6 near the Z-axis translation module 3, and the connecting bracket 7 is near the Y-axis translation module 2. A placement frame 8 is fixed on one side of the assembly. The placement frame 8 includes a pair of limiting discs and a rotating shaft. The rotating shaft is rotatably connected to the connecting frame 7. The limiting discs are engaged with the rotating shaft. It should be noted that the double-sided adhesive should be in roll form, and the hollow part of the roll form is compatible with the rotating shaft of the placement frame 8. Before use, the roll form of double-sided adhesive needs to be installed inside the placement frame 8. A sliding block 9 is slidably connected to the side of the connecting frame 7 near the bonding assembly 6. A placement plate 10 is installed on the side of the sliding block 9 near the bonding assembly 6. Multiple vent pipes are installed at the bottom of the placement plate 10. A lead screw is threaded to the outside of the sliding block 9. A drive motor is installed at the bottom of the lead screw. A breathable pad 11 is fixed on the surface of the placement plate 10. A limiting component 4 is provided below the bonding assembly 6. The limiting component 4 is installed on the top surface of the Y-axis translation module 2. The limiting component 4 is used to limit the injection molded part.During operation, the injection molded part to be bonded with double-sided adhesive is first placed inside the limiting component 4 for pre-positioning. Then, the positions of the X-axis translation module 1, Y-axis translation module 2, and Z-axis translation module 3 are adjusted sequentially to transport the injection molded part below the bonding component 6. The coordinated use of these modules achieves precise positioning of the injection molded part. After positioning, the drive motor connected to the sliding block 9 is activated, causing the sliding block 9 to slide. This movement of the sliding block 9 drives the placement plate 10, which first moves to the placement frame 8. Nearby, the internal venting pipe and the air pad 11 work together to create negative pressure on the surface of the placement plate 10, thereby adsorbing the double-sided adhesive. Then, the sliding block 9 slides again, causing the placement plate 10 to move below the bonding component 6. At this time, the negative pressure entering the placement plate 10 changes to air blowing, pushing the adsorbed double-sided adhesive to the bottom surface of the bonding component 6, where it is adsorbed. Then, the sliding block 9 resets, and the Z-axis translation module 3 descends, causing the bonding component 6 to descend, allowing the bonding component 6 to adhere to the surface of the injection molded part, thus attaching the double-sided adhesive to the injection molded part, completing the automatic double-sided adhesive application operation.

[0033] like Figure 3 As shown, the limiting component 4 includes a limiting frame 401, and multiple locking posts 403 are slidably connected inside the limiting frame 401. The locking posts 403 are hollow bosses. Multiple air inlets 402 are provided inside the limiting frame 401 and below the locking posts 403. During operation, after the injection molded part is placed inside the limiting component 4, air can be injected into the limiting frame 401 through the air inlets 402. The inflated locking posts 403 will rise under the action of air pressure. The raised locking posts 403 limit the injection molded part around its perimeter. In this way, it can adapt to injection molded parts of different shapes and types, improving the applicability of the equipment.

[0034] like Figure 3 As shown, a photoelectric sensor 404 is provided below the locking post 403, and a light-transmitting plate 405 is fixed inside the locking post 403 and directly above the photoelectric sensor 404. During operation, after the injection molded part is placed inside the limiting component 4, the photoelectric sensor 404 will detect the light on its top through the light-transmitting plate 405. The photoelectric sensor 404 that is blocked by the injection molded part will receive a signal. By setting multiple photoelectric sensors 404, the edge of the injection molded part can be effectively determined, thereby controlling the inflation position of the locking post 403, so that the locking post 403 located below the injection molded part will not be inflated and pushed up. In addition, this method can determine the exact position of the injection molded part installed inside the limiting component 4, which is convenient for subsequent precise positioning.

[0035] like Figure 3 As shown, multiple rubber bladders 407 are fixed inside the snap-fit ​​post 403. An electronic valve 406 is connected through the side of the rubber bladder 407 near the center of the snap-fit ​​post 403. During operation, after the snap-fit ​​post 403 is fully lifted, the electronic valve 406 is opened in a controlled manner, so that some gas is filled into the interior of the rubber bladder 407, causing the rubber bladder 407 to expand. The expanded rubber bladder 407 further covers the edge of the injection molded part, improving the stability of the installation. After the pasting is completed, the electronic valve 406 needs to be activated to release the air pressure inside the rubber bladder 407.

[0036] like Figure 4 As shown, the bonding component 6 includes an adsorption plate 601, with multiple air inlets installed at the top of the adsorption plate 601 and a sponge pad 602 fixed to the bottom surface of the adsorption plate 601. During operation, when the placement plate 10 lifts the double-sided adhesive to the bottom surface of the bonding component 6, the air inlets at the top of the adsorption plate 601 are connected, thereby generating a negative pressure to adsorb the lifted double-sided adhesive. The sponge pad 602 can disperse the pressure of the negative pressure, achieving a uniform pressure effect, which facilitates the subsequent bonding operation of the double-sided adhesive.

[0037] like Figure 4 As shown, both ends of the adsorption plate 601 are rotatably connected to a pair of rotating arms 603 via torsion springs. The end of each rotating arm 603 away from the adsorption plate 601 is rotatably connected to an extension rod 604 via a torsion spring. An auxiliary shaft 605 is rotatably connected between the ends of the pair of extension rods 604 away from the rotating arms 603. A drive motor is installed on the outside of each pair of rotating arms 603 near the Y-axis translation module 2. During operation, after the double-sided tape is pasted, the Y-axis translation module 2 drives the adsorption plate 601 to rise one distance. Then, the drive motor is started to drive the rotating arms 603 to rotate. The rotation of the rotating arms 603 drives the extension rods 604 to rotate. During the rotation of the extension rods 604, the auxiliary shaft 605 will roll back and forth on the pasted double-sided tape, thereby squeezing the pasted double-sided tape and improving the reliability of the double-sided tape pasting.

[0038] like Figures 5 to 6 As shown, a protective frame is fixed to the side of the placement rack 8 near the bonding component 6. The protective frame is fixedly connected to the connecting frame 7. A telescopic frame 21 is fixed to the top of the protective frame, and a cutter 20 is fixed to the bottom of the telescopic frame 21. During operation, when the double-sided tape is pulled out from the inside of the placement rack 8, it will be driven by the placement plate 10 to pass through the cutter 20. After the placement plate 10 moves into position, the telescopic frame 21 starts to drive the cutter 20 to cut the double-sided tape, thereby achieving the effect of automatically cutting the double-sided tape.

[0039] like Figures 5 to 6As shown, a support frame 22 is provided below the cutter 20. The top surface of the support frame 22 has a slot that matches the cutter 20. A whetstone is fixed on the inner surface of the slot. During operation, as the telescopic frame 21 moves the cutter 20 downward to cut the double-sided tape, the cutter 20 will come into contact with the support frame 22. During this process, the whetstone inside the slot will polish the surface of the cutter 20 to ensure the sharpness of the cutter 20, thereby ensuring that the cutter 20 can successfully cut the double-sided tape.

[0040] like Figures 5 to 6 As shown, a pair of support shafts 18 are rotatably connected inside the protective frame and between the telescopic frame 21 and the placement frame 8. During operation, before installing the double-sided tape, a portion of the double-sided tape needs to be pre-reserved to pass through the pair of support shafts 18. The support shafts 18 can support the double-sided tape, making it easier for the placement plate 10 to adhere the double-sided tape.

[0041] like Figures 5 to 6 As shown, multiple piercing heads 19 are fixed to the outside of the support shaft 18 located above. The piercing heads 19 are conical in shape. During operation, as the double-sided tape passes through the support shaft 18, the piercing heads 19 on the outside will pierce the centrifugal paper on the surface of the double-sided tape and pick out part of the centrifugal paper during rotation, thus facilitating the subsequent tearing of the double-sided tape.

[0042] Example 2

[0043] like Figure 7 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a beveled block 14 is fixedly connected to one end of the placement plate 10 near the sliding block 9; a beveled push block 13 is slidably connected to the top surface of the beveled block 14; a toggle rod 12 is fixed to the side of the beveled push block 13 away from the placement frame 8; a telescopic rod 16 is fixedly connected to the bottom end of the beveled block 14; and a return spring 15 is provided on the outside of the telescopic rod 16. During operation, when it is necessary to paste a longer piece of double-sided tape, if the length of the adsorption plate 601 is insufficient, the extension rod 604 can be placed by rotating the rotating arm 603 after the placement plate 10 has driven the double-sided tape to its position. As the double-sided adhesive has a certain strength, during the movement of the extension rod 604, it will drive the auxiliary shaft 605 to move over the double-sided adhesive and lift it up. During this process, the extension rod 604 will contact the toggle rod 12 and push the angled push block 13 to slide. The sliding of the angled push block 13 will drive the angled block 14 to compress the return spring 15 and move. The movement of the angled block 14 will drive the placement plate 10 to move, causing the placement plate 10 to separate from the double-sided adhesive. At this time, the bonding component 6 can normally adsorb the double-sided adhesive. At the same time, the auxiliary shaft 605 can also lift the double-sided adhesive that is too long, thus achieving the effect of adapting to the pasting of double-sided adhesive of different lengths.

[0044] like Figures 1 to 2As shown, multiple air blowing rods 17 are fixed to both sides of the placement plate 10. During operation, the air blowing rods 17 are designed to allow air to pass through them when the double-sided tape is too long, so that the airflow can blow the double-sided tape up, making it easier for the auxiliary shaft 605 to support it. It should be noted that after one end of the auxiliary shaft 605 is lifted, the placement plate 10 moves to the end of the bonding component 6 near the placement frame 8, so that the air blowing rods 17 blow air again, making it easier for the auxiliary shaft 605 to lift the double-sided tape.

[0045] Working Principle: The X-axis translation module 1, Y-axis translation module 2, and Z-axis translation module 3 are all existing technologies, which can be combinations of drive motors, lead screws, and sliders, and will not be elaborated further in this article. In use, the injection molded part to be bonded with double-sided adhesive is first placed inside the limiting component 4 for pre-positioning. Then, the positions of the X-axis translation module 1, Y-axis translation module 2, and Z-axis translation module 3 are adjusted sequentially, allowing the injection molded part to be transported below the bonding component 6. The coordinated use of the X-axis translation module 1, Y-axis translation module 2, and Z-axis translation module 3 achieves precise positioning of the injection molded part. After positioning, the drive motor connected to the sliding block 9 is activated, causing the sliding block 9 to slide. The sliding block 9, in turn, moves the placement plate 10. The placement plate 10 will first move to the vicinity of the placement frame 8, and... Then, through the cooperation of the internal vent pipe and the breathable pad 11, a negative pressure is formed on the surface of the placement plate 10, thereby adsorbing the double-sided adhesive. Then, the sliding block 9 slides again, driving the placement plate 10 to move below the bonding component 6. At this time, the negative pressure entering the placement plate 10 changes to air blowing, thereby pushing the double-sided adhesive adsorbed on its surface to the bottom surface of the bonding component 6, where it is adsorbed by the bonding component 6. Then, the sliding block 9 resets, and the Z-axis translation module 3 descends, driving the bonding component 6 to descend, so that the bonding component 6 is in contact with the surface of the injection molded part, thereby adhering the double-sided adhesive to the injection molded part, thus completing the automatic application of double-sided adhesive to the injection molded part. It should be noted that the double-sided adhesive should be in roll form, and the hollow part of the roll form should be compatible with the rotating shaft of the placement frame 8. Before use, the roll form of double-sided adhesive needs to be installed inside the placement frame 8.

[0046] After the injection molded part is placed inside the limiting assembly 4, air can be injected into the limiting frame 401 through the air inlet 402. The inflated locking posts 403 will then rise under the air pressure, limiting the injection molded part around its perimeter. This adapts to different shapes and types of injection molded parts, improving the equipment's versatility. After the injection molded part is placed inside the limiting assembly 4, the photoelectric sensor 404 detects the light from its top through the light-transmitting plate 405. Photoelectric sensors 404 that are blocked by the injection molded part will receive a signal. By using multiple photoelectric sensors 404, the location of the injection molded part can be effectively determined. The electronic valve 406 is opened in control of the inflation position of the locking post 403, preventing the locking post 403 located below the injection molded part from being inflated and pushed up. This method also allows for the determination of the exact position of the injection molded part installed inside the limiting component 4, facilitating subsequent precise positioning. After the locking post 403 is fully lifted, the electronic valve 406 is opened in control, allowing some gas to be injected into the rubber bladder 407, causing the rubber bladder 407 to expand. The expanded rubber bladder 407 further covers the edge of the injection molded part, improving the stability of the installation. After the bonding is completed, the electronic valve 406 needs to be activated to release the air pressure inside the rubber bladder 407.

[0047] When the placement plate 10 lifts the double-sided tape to the bottom surface of the bonding component 6, the air inlet pipe at the top of the adsorption plate 601 is connected, thereby generating negative pressure to adsorb the lifted double-sided tape. The sponge pad 602 can disperse the pressure of the negative pressure, achieving a uniform pressure effect, which facilitates the subsequent double-sided tape pasting operation. After the double-sided tape is pasted, the Y-axis translation module 2 drives the adsorption plate 601 to rise one distance, and then the drive motor is started to drive the rotating arm 603 to rotate. The rotation of the rotating arm 603 drives the extension rod 604 to rotate. During the rotation of the extension rod 604, it drives the auxiliary shaft 605 to roll back and forth on the pasted double-sided tape, thereby squeezing the pasted double-sided tape and improving the reliability of double-sided tape pasting.

[0048] When the double-sided tape is pulled out from inside the placement rack 8, it is driven by the placement plate 10 through the cutter 20. After the placement plate 10 moves into position, the telescopic frame 21 starts to drive the cutter 20 to cut the double-sided tape, thus achieving the effect of automatically cutting the double-sided tape. During the process of the telescopic frame 21 driving the cutter 20 to move downward to cut the double-sided tape, the cutter 20 will contact the support frame 22. During this process, the whetstone inside the slot will polish the surface of the cutter 20 to ensure the sharpness of the cutter 20, thus ensuring that the cutter 20 can successfully cut the double-sided tape. Before installing the double-sided tape, a portion of the double-sided tape needs to be reserved in advance to pass through a pair of support shafts 18. The support shafts 18 can support the double-sided tape, making it easy for the placement plate 10 to hold the double-sided tape. During the process of the double-sided tape passing through the support shafts 18, the piercing head 19 on the outside will pierce the centrifugal paper on the surface of the double-sided tape and pick out part of the centrifugal paper during the rotation, thus facilitating the subsequent tearing action of the double-sided tape.

[0049] When a longer section of double-sided tape needs to be pasted, and the length of the adsorption plate 601 is insufficient, the extension rod 604 can be lowered after the placement plate 10 moves the double-sided tape into position, causing the rotating arm 603 to rotate. Because the double-sided tape has a certain strength, during the movement of the extension rod 604, it will cause the auxiliary shaft 605 to move past the double-sided tape and lift it up. During this process, the extension rod 604 will contact the actuating rod 12, pushing the angled push block 13 to slide. The sliding of the angled push block 13 will cause the angled block 14 to compress the return spring 15 and move. The movement of the angled block 14 will then cause the placement plate 10 to move... The placement plate 10 is separated from the double-sided adhesive, at which point the bonding component 6 can properly adhere the double-sided adhesive. At the same time, the auxiliary shaft 605 can also lift the double-sided adhesive if it is too long, thus achieving the effect of accommodating double-sided adhesive of different lengths. The air blower 17 is designed so that when the double-sided adhesive is too long, air can be introduced into the air blower 17 to generate airflow to blow the double-sided adhesive up, making it easier for the auxiliary shaft 605 to lift it up. It should be noted that after one end of the auxiliary shaft 605 is lifted up, the placement plate 10 moves to the end of the bonding component 6 near the placement frame 8, so that the air blower 17 blows air again, making it easier for the auxiliary shaft 605 to lift the double-sided adhesive up.
