Description

Technical Field

[0001] This application relates to the field of auxiliary material processing technology, and in particular to a precise positioning auxiliary material mounting mechanism. Background Technology

[0002] Auxiliary materials are materials that play a supporting role in product manufacturing. Their applications are very wide-ranging. For example, mobile phones currently require a wide variety of auxiliary materials, including shielding covers, cushioning foam, foils, insulating PI, heat sinks, conductive adhesives, double-sided tape, and so on. Since various surfaces of a product may require auxiliary materials, most current auxiliary material mounting equipment requires placing the product in a fixture and then using a robotic arm to mount the auxiliary materials onto the product. When mounting auxiliary materials on the top or bottom surface of the product, the product needs to be stood upright before being placed on the fixture. The fixture clamps the product from the side to secure it. During this process, the robotic arm needs to rotate the product while standing it upright. If the robotic arm has been used for a long time, its parts are prone to wear, which may cause the robotic arm to not rotate completely, resulting in the product being slightly tilted after being placed on the fixture. This can lead to misalignment of the auxiliary materials when mounted, reducing the accuracy of the mounting process. Summary of the Invention

[0003] The purpose of this application is to provide a precise positioning auxiliary material placement mechanism that can automatically correct the product so that it is placed vertically on the fixture, which helps to make the product positioning accurate and thus improves the accuracy of auxiliary material placement.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a precision positioning auxiliary material application mechanism, including a machine base, wherein the machine base is provided with a fixture for fixing products, an auxiliary material feeding component, a product robot, and a correction component. The correction component is used to correct the product to a vertical state. The product robot is used to transport the product to the correction component or the fixture by adsorption. The auxiliary material feeding component is used to apply the auxiliary material to the product on the fixture. The correction component includes two relatively movable movable parts. A correction groove that fits the product is opened on the facing side of the movable parts. The two movable parts are used to merge from both sides of the product to place the product in the correction groove. An avoidance groove for the product robot to adsorb the product is also opened on the side of the movable parts.

[0005] By adopting the above technical solution, during use, the product robot first picks up the product, then rotates it to stand it up. The product robot then moves the product horizontally into the correction component, between two moving parts. The two moving parts merge, and at the same time, the product robot releases the product. The two moving parts merge to clamp the product in the correction groove, thereby correcting the tilted product to a vertical position. The product robot picks up the product again, the two moving parts separate, and the product robot then transports the product to the fixture. Finally, the auxiliary material feeding component performs auxiliary material application on the product on the fixture. The setting of the correction component ensures that the product is in a vertical position before the product robot transports it to the fixture. The product robot then transports the product to the fixture by horizontal movement, thus ensuring that the product is in a vertical position when the fixture clamps it. This is beneficial for the accurate positioning of the product and, in turn, improves the accuracy of auxiliary material application.

[0006] Preferably, the correction assembly further includes a base fixed to the machine platform, a guide rail provided on the base, both movable parts being slidably mounted on the guide rail, and a moving structure cooperating on one side of each movable part, the moving structure being used to drive the two movable parts to move synchronously towards each other or away from each other along the guide rail.

[0007] By adopting the above scheme, the guide rail setting helps to make the movement direction of the two moving parts more stable, and the moving structure drives the two moving parts to move on the guide rail.

[0008] Preferably, the moving structure includes two crank assemblies arranged symmetrically on the left and right sides. The two crank assemblies are respectively connected to the two movable parts. Each crank assembly includes a disc, a connecting rod, and a driven gear. The disc is vertically rotatably mounted on the base. One end of the connecting rod is rotatably connected to the back side of the movable part, and the other end of the connecting rod is rotatably connected to the outer edge of the disc. The driven gear is concentrically connected to the side of the disc opposite to the connecting rod and is located on the other side of the base. A first motor is also provided on the base. A driving gear is sleeved on the output shaft of the first motor. The driving gear is located between the two driven gears of the two crank assemblies, and the driving gear meshes with both driven gears.

[0009] By adopting the above technical solution, the driving gear rotates synchronously with the two driven gears under the drive of the first motor. Since the two driven gears are located on both sides of the driving gear, the two driven gears rotate in opposite directions, which makes the two discs rotate in opposite directions. The discs then drive the moving parts to translate through the connecting rod, thereby realizing the synchronous movement of the two moving parts towards or away from each other. Using one driving gear to synchronously drive the two driven gears to rotate is beneficial to improving the synchronicity of the movement of the two moving parts.

[0010] Preferably, the correction groove includes a guide groove, the size of which gradually decreases inward from the opening, and the bottom of the guide groove is also provided with a receiving groove, the shape of which is the same as the shape of the product, and the guide groove is used to guide the product into the receiving groove.

[0011] By adopting the above scheme, the guide groove is designed to allow the product to enter the receiving groove more smoothly when the two moving parts move towards each other, thereby correcting the product.

[0012] Preferably, the machine platform is further provided with a turntable, and the number of clamps is several, and the clamps are evenly distributed on the turntable along the edge of the turntable.

[0013] By adopting the above scheme, the turntable configuration enables the equipment to simultaneously apply auxiliary materials to products on fixtures at different workstations through multiple auxiliary material feeding components, which helps to improve production efficiency.

[0014] Preferably, the clamp includes a support member and a clamping member. The support member is fixedly installed on the turntable. A placement slot for placing products is provided on one side of the support member. The placement slot extends through the top of the support member. The clamping member is located on the side of the support member opposite to the placement slot. The clamping member is slidably installed on the turntable via a guide rail. A spring is also provided between the clamping member and the support member. The clamping member extends through the support member and is used to clamp the product in the placement slot.

[0015] By adopting the above solution, the clamping component uses the spring to hold the product in the placement slot, thereby fixing the product.

[0016] Preferably, the machine base is further provided with a feeding assembly, which includes a feeding cylinder and a feeding pusher. The feeding cylinder is installed on the machine base, located below the turntable and at the feeding station. The feeding pusher is installed on the feeding cylinder. A push rod is provided at the bottom of the clamping member, which passes through the turntable and is located in front of the feeding pusher.

[0017] By adopting the above scheme, during unloading, the clamp rotates to the unloading station, the push rod is located in front of the unloading push block, the unloading cylinder drives the unloading push block forward, thereby driving the push rod forward, causing the clamping part to compress the spring, thereby causing the clamping part to release the product placed in the slot.

[0018] Preferably, the product robot includes a first horizontal linear module mounted on the machine base, a first vertical linear module disposed on the first horizontal linear module, a rotary cylinder connected to the first vertical linear module, a second vertical linear module disposed on the rotary cylinder, the rotary cylinder being used to drive the second vertical linear module to rotate in a vertical plane perpendicular to the first horizontal linear module, a second motor disposed on the second vertical linear module, a rotating shaft connected to the output shaft of the second motor, and a product suction head for adsorbing products disposed at the end of the rotating shaft away from the second motor.

[0019] By adopting the above scheme, the product suction head moves to the feeding position under the drive of the first horizontal linear module, the first vertical linear module, and the second vertical linear module and sucks up the product to be attached. The first vertical linear module then lifts the product suction head, and the rotary cylinder drives the second vertical linear module to rotate so that the product suction head faces the correction component. The second motor then drives the product to rotate to a vertical position through the rotating shaft. Under the drive of the second vertical linear module, the product suction head places the product in the correction component, thereby realizing the conveying of the product to be attached.

[0020] Preferably, the auxiliary material feeding assembly includes a feeding structure and an auxiliary material robot for attaching the auxiliary material from the feeding structure to the product. The feeding structure includes a material sheet base plate and a material sheet cover plate for placing the material sheet. The material sheet cover plate covers the material sheet base plate to clamp the material sheet. A feeding translation module along the length direction of the material sheet is also provided below the material sheet base plate. A lifting cylinder is provided on the feeding translation module, and a lifting pin is provided on the lifting cylinder for lifting the auxiliary material.

[0021] By adopting the above scheme, the material sheet is placed between the material sheet base plate and the material sheet cover plate, and then the auxiliary material is lifted by the ejector pin to peel the auxiliary material off the material sheet, thereby realizing the feeding.

[0022] Preferably, the auxiliary material robot includes a support frame, on which a second horizontal linear module, a third horizontal linear module, and a third vertical linear module are disposed. The second horizontal linear module is mounted on the support frame, the third horizontal linear module is mounted on the second horizontal linear module and is perpendicular to the second horizontal linear module, and the third vertical linear module is mounted on the third horizontal linear module. The third vertical linear module is provided with an auxiliary material suction head for adsorbing auxiliary materials.

[0023] By adopting the above scheme, the second horizontal linear module, the third horizontal linear module, and the third vertical linear module work together to drive the auxiliary material suction head from the feeding structure to the product.

[0024] In summary, the beneficial technical effects of this application are as follows:

[0025] 1. Setting up the correction component: Before the product robot is transported to the fixture, the product is in a vertical position. The product robot then transports the product to the fixture by translation, thus ensuring that the product is in a vertical position when the fixture clamps the product. This is conducive to the accurate positioning of the product and thus helps to improve the accuracy of auxiliary material placement.

[0026] 2. Using one driving gear to synchronously drive two driven gears is beneficial to improving the synchronicity of the movement of the two moving parts.

[0027] 3. The guide groove is designed to allow the product to enter the receiving groove more smoothly when the two moving parts move towards each other, thereby correcting the product. Attached Figure Description

[0038] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0039] This application discloses a precise positioning auxiliary material mounting mechanism, such as... Figure 1 and Figure 2As shown, the machine includes a base 1, on which are mounted a clamp 2 for fixing products, an auxiliary material feeding assembly 3, a product robot 4, and a correction assembly 5. The correction assembly 5 is used to correct the product to a vertical position. The product robot 4 is used to transport the product to the correction assembly 5 or the clamp 2 by suction. The auxiliary material feeding assembly 3 is used to attach auxiliary materials to the product on the clamp 2. The correction assembly 5 includes two movable parts 51 that can move relative to each other. The opposing surfaces of the movable parts 51 have correction grooves that fit the product. The two movable parts 51 are used to merge from both sides of the product to place the product in the correction groove. The sides of the movable parts 51 also have clearance grooves 52 for the product robot 4 to suction the product. In use, the product robot 4 first suctions the product, and then rotates to stand the product upright. The robotic arm 4 then moves the product horizontally into the correction component 5, between the two moving parts 51. The two moving parts 51 merge, and at the same time, the robotic arm 4 releases the product. The two moving parts 51 merge to clamp the product in the correction groove, thereby correcting the tilted product to a vertical position. The robotic arm 4 then picks up the product again, the two moving parts 51 separate, and the robotic arm 4 then transports the product to the fixture 2. Finally, the auxiliary material loading component 3 performs auxiliary material application on the product on the fixture 2. The setting of the correction component 5 ensures that the product is in a vertical position before the robotic arm 4 transports the product to the fixture 2. The robotic arm 4 then transports the product to the fixture 2 by horizontal movement, thereby ensuring that the product is in a vertical position when the fixture 2 clamps the product. This is beneficial for the accurate positioning of the product and thus improves the accuracy of auxiliary material application.

[0040] Specifically, such as Figures 2-4As shown, the correction assembly 5 also includes a base 53 fixed on the machine base 1. A guide rail 54 is provided on the base 53, and two movable parts 51 are slidably mounted on the guide rail 54. In this embodiment, the guide rail 54 is specifically a T-shaped guide rail 54. The bottom of each of the two movable parts 51 is provided with a movable groove that fits into the T-shaped guide rail 54. The two movable parts 51 are sleeved on the guide rail 54 through the movable groove. A moving structure is provided on one side of each movable part 51. The moving structure is used to drive the two movable parts 51 to move synchronously towards each other or away from each other along the guide rail 54. The guide rail 54 helps to stabilize the directional movement of the two movable parts 51. The moving structure drives the two movable parts 51 to move on the guide rail 54. The moving structure includes two crank assemblies arranged symmetrically on the left and right. The two crank assemblies are respectively connected to the two movable parts 51. The crank assembly includes a disc 55, a connecting rod 56, and a driven gear 57. The disc 55 is vertically rotatably mounted on the base 53. One end of the connecting rod 56 is rotatably connected to the back side of the movable part 51, and the other end of the connecting rod 56 is connected to the outer side of the disc 55. The driven gear 57 is concentrically connected to the side of the disc 55 away from the connecting rod 56, and is located on the other side of the base 53. The driven gears 57 of the two crank assemblies are the same size. A first motor 58 is also provided on the base 53. A driving gear 59 is sleeved on the output shaft of the first motor 58. The driving gear 59 is located between the two driven gears 57 of the two crank assemblies, and the driving gear 59 meshes with both driven gears 57. The driving gear 59 rotates the synchronous belt under the drive of the first motor 58. The two driven gears 57 rotate. Since the two driven gears 57 are located on both sides of the driving gear 59, the two driven gears 57 rotate in the same direction and at the same speed. This causes the two disks 55 to rotate in opposite directions. The disks 55 then drive the movable part 51 to translate through the connecting rod 56, thereby realizing that the two movable parts 51 move synchronously towards or away from each other. Using one driving gear 59 to synchronously drive the two driven gears 57 to rotate is beneficial to improving the synchronicity of the movement of the two movable parts 51.

[0041] In this embodiment, as Figure 3 As shown, the correction groove includes a guide groove 521, the size of which gradually decreases from the opening inwards. The guide groove 521 is specifically frustum-shaped. The bottom of the guide groove 521 is also provided with a receiving groove 522, the shape of which is the same as that of the product. The guide groove 521 is used to guide the product into the receiving groove 522. The setting of the guide groove 521 is conducive to the product entering the receiving groove 522 more smoothly when the two moving parts 51 move towards each other, thereby correcting the product.

[0042] The machine 1 is also equipped with a turntable 6. In this embodiment, there are six clamps 2, which are evenly distributed along the edge of the turntable 6. The turntable 6 allows the equipment to simultaneously apply auxiliary materials to the products on the clamps 2 at different workstations through multiple auxiliary material feeding components 3, which helps to improve production efficiency. Figure 5 As shown, the clamp 2 includes a support member 21 and a clamping member 22. The support member 21 is fixedly installed on the turntable 6. A placement groove 23 for placing products is opened on one side of the support member 21. The placement groove 23 passes through the top of the support member 21. The clamping member 22 is located on the side of the support member 21 away from the placement groove 23, and the clamping member 22 is slidably installed on the turntable 6 via a guide rail. A spring 24 is also provided between the clamping member 22 and the support member 21. The clamping member 22 passes through the support member 21 and is used to place the product in the placement groove 23. The part of the clamping member 22 that passes through the support member 21 is designed in the shape of a hook. Under the action of the spring 24, the clamping member 22 clamps the product in the placement groove 23, thereby fixing the product.

[0043] In addition, the machine base 1 is also equipped with a feeding assembly 7, which includes a feeding cylinder 71 and a feeding pusher 72. The feeding cylinder 71 is installed on the machine base 1 and is located below the turntable 6 and at the feeding station. The feeding pusher 72 is installed on the feeding cylinder 71. Each clamp 2 has a pusher 25 at the bottom of its clamping member 22. The pusher 25 passes through the turntable 6 and is located in front of the feeding pusher 72. When feeding, the clamp 2 rotates to the feeding station, and the pusher 25 is located in front of the feeding pusher 72. The feeding cylinder 71 drives the feeding pusher 72 forward, thereby driving the pusher 25 forward, so that the clamping member 22 compresses the spring 24, thereby causing the clamping member 22 to release the product in the placement slot 23.

[0044] like Figure 6As shown, the product robot 4 includes a first horizontal linear module 41 mounted on a machine base 1. A first vertical linear module 42 is mounted on the first horizontal linear module 41. A rotary cylinder 43 is connected to the first vertical linear module 42. A second vertical linear module 44 is mounted on the rotary cylinder 43. The rotary cylinder 43 drives the second vertical linear module 44 to rotate in a vertical plane perpendicular to the first horizontal linear module 41. A second motor 45 is mounted on the second vertical linear module 44. A rotating shaft 46 is connected to the output shaft of the second motor 45. A product suction head 47 for adsorbing products is located at the end of the rotating shaft 46 away from the second motor 45. In this embodiment, the product suction head 47 is specifically a vacuum suction head. Under the drive of the first horizontal linear module 41, the first vertical linear module 42, and the second vertical linear module 44, the product suction head 47 moves to the feeding position and sucks up the product to be attached. The first vertical linear module 42 then lifts the product suction head 47. The rotary cylinder 43 drives the second vertical linear module 44 to rotate so that the product suction head 47 faces the correction component 5. The second motor 45 then drives the product to rotate to a vertical state through the rotating shaft 46. Under the drive of the second vertical linear module 44, the product suction head 47 places the product in the correction component 5, thereby realizing the conveying of the product to be attached.

[0045] The auxiliary material feeding assembly 3 includes a feeding structure 31 and an auxiliary material robot 32 for attaching auxiliary materials from the feeding structure 31 to the product, such as... Figure 7 and Figure 8 As shown, the feeding structure 31 includes a sheet base plate 311 for placing sheet materials and a sheet cover plate 312. The sheet cover plate 312 covers the sheet base plate 311 to clamp the sheet material. Below the sheet base plate 311, a feeding translation module 313 along the length of the sheet material is also provided. The feeding translation module 313 is provided with a lifting cylinder 314. The lifting cylinder 314 is provided with a ejector pin 315 for lifting auxiliary materials. The sheet material is placed between the sheet base plate 311 and the sheet cover plate 312, and then the ejector pin 315 lifts the auxiliary materials to peel them off from the sheet material, thereby realizing the feeding. The auxiliary material robot 32 includes a support frame 321, and a second transverse linear module is provided on the support frame 321. 322, a third horizontal linear module 323, and a third vertical linear module 324. The second horizontal linear module 322 is mounted on the support frame 321. The third horizontal linear module 323 is mounted on the second horizontal linear module 322 and is perpendicular to the second horizontal linear module 322. The third vertical linear module 324 is mounted on the third horizontal linear module 323. The third vertical linear module 324 is provided with an auxiliary material suction head 325 for adsorbing auxiliary materials. The second horizontal linear module 322, the third horizontal linear module 323, and the third vertical linear module 324 cooperate with each other to drive the auxiliary material suction head 325 from the feeding structure 31 to the product.

[0046] The implementation principle of this embodiment is as follows:

[0047] The product suction head 47, driven by the first horizontal linear module 41, the first vertical linear module 42, and the second vertical linear module 44, moves to the feeding position and picks up the product to be attached. The first vertical linear module 42 then lifts the product suction head 47. The rotary cylinder 43 drives the second vertical linear module 44 to rotate so that the product suction head 47 faces the correction component 5. The second motor 45 then drives the product to rotate to a vertical position through the rotating shaft 46. The product suction head 47, driven by the second vertical linear module 44, places the product onto the feed plate. Placed in the correction assembly 5, the two movable parts 51 merge under the drive of the moving structure. Before the two movable parts 51 completely merge, the product suction head 47 is located at the relief groove 52 and releases the product. The product is then inserted into the receiving groove 522 under the guidance of the guide groove 521, thereby completing the correction of the product. The product suction head 47 then re-adsorbs the product from the relief groove 52. After that, the two movable parts 51 separate under the drive of the moving structure. The product suction head 47 then transports the product to the fixture 2 for auxiliary material mounting.
