Description

Technical Field

[0001] This utility model relates to the field of plastic sheet bonding technology, and more specifically, to a stamping and conveying mechanism for plastic sheet bonding. Background Technology

[0002] In production, a plastic sheet with adhesive is attached to a microphone soft rubber for mounting at the hole of a vehicle microphone.

[0003] In existing technologies, the attachment of plastic sheets to microphone adhesive is usually completed using a single-station stamping device. This method has significant drawbacks: First, the sequential operation of a single station leads to low attachment efficiency; second, from the time the plastic sheet is placed on the microphone adhesive until the attachment is completed, the plastic sheet is prone to positional shift (this is mainly due to the plastic sheet's light weight, smooth surface, and easy sliding, which may cause slight positioning errors during placement and removal, and the lack of lateral constraint after placement, making it susceptible to displacement due to vibration or the inertia of the mechanism). Existing technologies lack effective dynamic correction and position fixing mechanisms, which causes the actual position of the plastic sheet to deviate from the predetermined position during stamping and attachment, resulting in the microphone adhesive not being accurately attached to the designated area of ​​the plastic sheet, seriously affecting the product qualification rate. Utility Model Content

[0004] The purpose of this invention is to provide a stamping and conveying mechanism for bonding plastic sheets, so as to solve the problems mentioned in the background art.

[0005] The plastic sheet is prone to shifting in position after it is placed on the upper side of the microphone rubber but before the attachment is completed.

[0006] To address the above problems, the present invention aims to provide a stamping and conveying mechanism for bonding plastic sheets, comprising a base, a movable block slidably disposed on the upper side wall of the base, and support rods vertically fixedly disposed near the four corners of the upper side wall of the movable block. The upper ends of the four support rods are horizontally fixedly disposed on the same support platform. Two material feeding grooves are symmetrically formed on the upper side wall of the support platform, one end of each groove extending to the edge of the support platform to form an opening. A through groove is formed at the bottom of the material feeding groove, extending to the lower side wall of the support platform. The upper side wall of the support platform connects with the two... Telescopic cylinders are fixedly installed at the corresponding positions of the through slots. The upper end of the piston rod of the telescopic cylinder extends into the corresponding through slot and is fixedly installed with a nylon top block. A positioning mechanism is set near the opening of the feeding slot. A material picking mechanism for picking up and putting down plastic sheets is set on one side of the support platform. When the material picking mechanism places the plastic sheet into one of the feeding slots, the piston rod of the telescopic cylinder at the corresponding position extends and drives the nylon top block to move upward, so that the upper end of the nylon top block extends out of the through slot. At the same time, the piston rod of the telescopic cylinder drives the positioning mechanism to fix the position of the plastic sheet.

[0007] As a further improvement to this technical solution, an installation groove is provided at the opening at the bottom of the material discharge trough, and the positioning mechanism includes a rotating plate rotatably disposed at the top of the installation groove. An L-shaped plate is fixedly disposed on the piston rod of the telescopic cylinder, and the other end of the L-shaped plate slides in contact with one side of the rotating plate.

[0008] As a further improvement to this technical solution, the positioning mechanism also includes two extension rods respectively fixedly disposed on both sides of the L-shaped plate away from the telescopic cylinder. Positioning frames are fixedly disposed on the L-shaped plate at positions corresponding to the two extension rods, and the extension rods are slidably disposed inside the corresponding positioning frames.

[0009] As a further improvement to this technical solution, when the nylon top block is located inside the through groove, the rotating plate is in a horizontal state, and the side of the rotating plate away from the L-shaped plate is spliced ​​with the bottom surface of the discharge groove to form a complete plane.

[0010] As a further improvement to this technical solution, when the piston rod of the telescopic cylinder extends and drives the upper end of the nylon top block to extend out of the through groove, the L-shaped plate pushes the rotating plate to rotate to a vertical state.

[0011] As a further improvement to this technical solution, the material handling mechanism includes a lead screw slide fixedly installed on the upper side wall of the base. A blade cylinder is fixedly installed on the upper side wall of the lead screw slide via a bracket. The piston rod end of the blade cylinder is fixedly connected to a vertically arranged hollow guide rod via an end plate. A suction cup is fixedly installed at the lower end of the hollow guide rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. In this plastic sheet bonding stamping and conveying mechanism, after the material handling mechanism places the plastic sheet on the predetermined position on the upper side of the microphone soft rubber, the piston rod of the telescopic cylinder extends, driving the top block and L-shaped plate to move upward synchronously. The upward movement of the L-shaped plate pushes the rotating plate to rotate. When the rotating plate rotates to the tilted state, if the plastic sheet has a positional deviation, its deviated side will contact the rotating plate. At this time, the rotating plate will push the plastic sheet to move closer to the inner wall of the feeding trough, realizing automatic correction of the plastic sheet. As the rotating plate continues to rotate to the vertical state, the rotating plate itself and the inner wall of the feeding trough are in contact with the plastic sheet, thereby fixing the position of the plastic sheet in the feeding trough. This effectively avoids the positional deviation of the plastic sheet during the bonding process with the microphone soft rubber, ensuring the accuracy of the microphone soft rubber's attachment position on the plastic sheet.

[0014] 2. In the plastic sheet bonding stamping and conveying mechanism, after the plastic sheet to be bonded is unloaded in one of the feeding troughs, the shifting cylinder drives the platform to move horizontally, so that the idle feeding trough moves again to the discharge end of the linear guide rail to receive the material, while the microphone soft glue received in the other feeding trough is ready for the next round of bonding operation. This realizes the staggered operation of the two feeding troughs, which improves the bonding efficiency of microphone soft glue and plastic sheet. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figure 1 As shown, the purpose of this embodiment is to provide a stamping and conveying mechanism for bonding plastic sheets, including a base 1. A movable block 3 is slidably arranged on the upper side wall of the base 1. A displacement cylinder 7 is horizontally fixedly installed on the upper side wall of the base 1. The piston rod end of the displacement cylinder 7 is fixedly connected to the movable block 3. The movable block 3 can be moved horizontally by extending and retracting the piston rod of the displacement cylinder 7. At the same time, two sliding rods are slidably arranged on the movable block 3. Both ends of the sliding rods are fixed on the base 1. The sliding rods are used to limit the sliding trajectory of the movable block 3. Support rods 31 are vertically fixedly arranged near the four corners of the upper side wall of the movable block 3. The upper ends of the four support rods 31 are horizontally fixedly arranged with the same support platform 4. Two material discharge grooves 41 are symmetrically opened on the upper side wall of the support platform 4. One end of the material discharge groove 41 extends through to the edge of the support platform 4 to form an opening.

[0031] When this mechanism is in use, the support platform 4 is installed on one side of an external linear guide rail. This linear guide rail is used to transport microphone soft glue, and vertically arranged pen cylinders are fixedly installed on both sides of the linear guide rail. A pressure head is fixedly installed at the lower end of the piston rod of the pen cylinder. The extension and retraction of the piston rod of the displacement cylinder 7 drives the moving block 3 to move horizontally, and the position of the support platform 4 is adjusted synchronously. This allows the openings of the two feeding troughs 41 to be connected to the discharge end of the linear guide rail. Thus, the linear guide rail can transport the microphone soft glue through the openings into the interior of the two feeding troughs 41, so that both feeding troughs 41 can receive the microphone soft glue. After the feeding trough 41 receives the microphone soft glue, the extension or retraction of the piston rod of the displacement cylinder 7 drives the moving block 3 and the support platform 4 to move horizontally. This moves the microphone soft glue to be stamped to directly below the pressure head of any pen cylinder (i.e., the stamping station), completing the stamping preparation work.

[0032] A material handling mechanism 2 for picking up and placing plastic sheets is provided on the side of the platform 4 away from the linear guide rail. The structure of the material handling mechanism 2 is described in detail below, referring to... Figure 4 and Figure 5 The material handling mechanism 2 includes a lead screw slide 21 fixedly installed on the upper side wall of the base 1. A blade cylinder 22 is fixedly installed on the upper side wall of the lead screw slide 21 via a bracket. The piston rod end of the blade cylinder 22 is fixedly connected to a vertically arranged hollow guide rod 23 via an end plate. A suction cup 24 is fixedly installed at the lower end of the hollow guide rod 23. A vacuum pump is externally connected to the upper end of the hollow guide rod 23 via a hose.

[0033] The initial position of the suction cup 24 corresponds to the position of the external plastic sheet production line. When the piston rod of the blade cylinder 22 extends and drives the suction cup 24 to contact the plastic sheet on the external production line, the vacuum pump evacuates the inside of the suction cup 24, causing the suction cup 24 to adsorb the plastic sheet. Then, the piston rod of the blade cylinder 22 retracts, driving the suction cup 24 and the adsorbed plastic sheet to move upward, causing the plastic sheet to detach from the production line. Next, the lead screw slide 21 drives the blade cylinder 22 and the suction cup 24 to move towards the support table 4 until the plastic sheet is moved directly above the microphone soft rubber located at the stamping station. Then, the piston rod of the blade cylinder 22 extends, driving the plastic sheet downward until the plastic sheet contacts the microphone soft rubber. Finally, the vacuum pump injects air into the suction cup 24 to release the vacuum adsorption. The plastic sheet is then stacked on the predetermined position on the upper side of the microphone soft rubber. The suction cup 24 is reset to its initial state by the drive of the lead screw slide 21 and the blade cylinder 22, thus completing the loading of the plastic sheet.

[0034] A through groove 42 is provided at the bottom of the feeding trough 41, and the through groove 42 extends to the lower side wall of the support platform 4. When the feeding trough 41 receives the microphone soft rubber, the microphone soft rubber is located directly above the through groove 42, and the outer diameter of the through groove 42 is smaller than the outer diameter of the microphone soft rubber, so as to prevent the microphone soft rubber from falling to the bottom of the support platform 4 through the through groove 42. Telescopic cylinders 5 are fixedly installed on the upper side wall of the support platform 4 at positions corresponding to the two through grooves 42. The upper end of the piston rod of the telescopic cylinder 5 extends into the corresponding through groove 42 and is fixedly provided with a nylon top block 51.

[0035] After the plastic sheet is placed in the predetermined position on the upper side of the microphone soft rubber, the piston rod of the telescopic cylinder 5 extends and drives the nylon top block 51 to move vertically upward, so that the nylon top block 51 pushes the microphone soft rubber upward. At the same time, the piston rod of the pen cylinder extends and drives the pressure head to move downward. The pressure head presses the plastic sheet located at the stamping station downward. Thus, the microphone soft rubber and the plastic sheet are attached together by the upper and lower cooperation of the pressure head and the nylon top block 51.

[0036] To ensure the accuracy of the microphone adhesive's placement on the plastic sheet, a positioning mechanism 6 is provided near the opening of the feeding slot 41. When the feeding mechanism 2 places the plastic sheet inside one of the feeding slots 41, the piston rod of the corresponding telescopic cylinder 5 extends, causing the nylon top block 51 to move upward, so that the upper end of the nylon top block 51 extends out of the through slot 42 to contact the plastic sheet. At the same time, the piston rod of the telescopic cylinder 5 drives the positioning mechanism 6, so that the positioning mechanism 6 cooperates with the feeding slot 41 to fix the position of the plastic sheet, preventing the position of the plastic sheet from shifting during the application process, and ensuring that the microphone adhesive is accurately attached to the predetermined position on the plastic sheet.

[0037] An installation groove 43 is provided at the opening at the bottom of the material discharge trough 41. The structure of the positioning mechanism 6 is described in detail below, referring to... Figure 2 and Figure 3The positioning mechanism 6 includes a rotating plate 61 rotatably mounted at the top of the mounting groove 43. An L-shaped plate 63 is fixedly mounted on the piston rod of the telescopic cylinder 5. The other end of the L-shaped plate 63 slides in contact with one side of the rotating plate 61. The positioning mechanism 6 also includes two extension rods 631 fixedly mounted on both sides of the L-shaped plate 63 away from the telescopic cylinder 5. Positioning frames 62 are fixedly mounted on the L-shaped plate 63 at positions corresponding to the two extension rods 631. The extension rods 631 slide inside the corresponding positioning frames 62.

[0038] When the nylon top block 51 is inside the through groove 42, the rotating plate 61 is in a horizontal state, and the side of the rotating plate 61 away from the L-shaped plate 63 is spliced ​​with the bottom surface of the feeding groove 41 to form a complete plane, ensuring that the linear guide rail can transport the microphone soft rubber into the feeding groove 41. When the piston rod of the telescopic cylinder 5 extends and drives the upper end of the nylon top block 51 out of the through groove 42, the piston rod of the telescopic cylinder 5 drives the L-shaped plate 63 to move upward synchronously. The L-shaped plate 63 pushes the rotating plate 61 to first rotate to an inclined state, and then to a vertical state. When the plastic sheet is stacked on the predetermined position on the upper side of the microphone soft rubber, the plastic... The plastic sheet is also located inside the feeding trough 41. When the rotating plate 61 is rotated to the tilted state, if the plastic sheet is misaligned, one side of the plastic sheet will contact the rotating plate 61. The rotating plate 61 will push the plastic sheet to move closer to the inner wall of the feeding trough 41, thereby correcting the plastic sheet's misalignment. When the rotating plate 61 is rotated to the vertical state, both the rotating plate 61 and the inner wall of the feeding trough 41 are in contact with the plastic sheet. The cooperation between the rotating plate 61 and the inner wall of the feeding trough 41 fixes the position of the plastic sheet inside the feeding trough 41, preventing the plastic sheet from shifting its position during the application of the microphone adhesive.

[0039] It should be noted that when the rotating plate 61 corrects the plastic sheet, the pen holder cylinder has not yet driven the pressure head to press the plastic sheet. This avoids the pressure head from obstructing the correction action of the plastic sheet. After the rotating plate 61 and the inner wall of the feeding groove 41 are in place to fix the position of the plastic sheet, the pressure head will start to press the plastic sheet down, thereby ensuring that the microphone soft glue is accurately attached to the predetermined position on the plastic sheet.

[0040] After the microphone soft adhesive and plastic sheet are attached, the piston rod of the telescopic cylinder 5 retracts, causing the nylon top block 51 and L-shaped plate 63 to move down and reset. During this process, the L-shaped plate 63 drives the extension rod 631 to move synchronously. After the extension rod 631 contacts the inner wall of the positioning frame 62, it pushes the positioning frame 62 and the rotating plate 61 connected to it to rotate back to the horizontal state. An air pipe is arranged on the side of the material discharge trough 41 away from the opening. The air pipe sprays out a high-speed airflow, blowing the attached microphone soft adhesive and plastic sheet out of the material discharge trough 41 through the opening, thus completing the material discharge work.

[0041] Subsequently, the shifting cylinder 7 drives the support platform 4 to move horizontally, so that the idle feeding slot 41 moves again to the discharge end of the linear guide rail to receive the material, while the microphone soft glue received in the other feeding slot 41 is ready for the next round of attachment operation. The above steps are repeated to realize the staggered operation of the two feeding slots 41, which improves the attachment efficiency of microphone soft glue and plastic sheet.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
