Description

Technical Field

[0001] This invention relates to the field of welding fixtures, and in particular to a welding fixture for a mobile phone vibrator. Background Technology

[0002] Vibration is a standard feature in mobile phones. It is usually achieved by a vibrator inside the phone. The vibrator consists of a housing and an inner core mover inside the housing. Both ends of the inner core mover are connected to the inner wall of the housing by leaf springs. The principle is to energize a coil on the housing to generate a magnetic field, which drives the inner core mover to vibrate. However, as mobile phones become thinner, the vibrator inevitably becomes smaller. The gap between the inner core mover and the housing on one side is usually only 0.18mm, which makes the assembly of the vibrator increasingly difficult.

[0003] In the existing technology, the welding process of mobile phone vibrators first requires assembling the inner core mover into the outer shell, and then welding the leaf spring connecting the inner core mover to the inner wall of the outer shell. However, the existing assembly method of the inner core mover and the outer shell usually involves first positioning and fixing the outer shell onto a fixture, and then installing the inner core mover into the outer shell. Due to manufacturing errors in the inner core mover and the outer shell, the product itself has dimensional tolerances. Under this assembly method, it is difficult to guarantee the central symmetry requirement of the inner core mover inside the outer shell. The existence of deviation will affect the vibration performance of the inner core mover.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Summary of the Invention

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a welding fixture for a mobile phone vibrator. This fixture features a positioning part on the product mounting base for positioning the inner core mover in the front-to-back direction. This, combined with a centering positioning device for left-to-right centering of the inner core mover and the outer shell, and a clamping mechanism for front-to-back centering of the outer shell, ensures the inner core mover is accurately placed within the outer shell, guaranteeing its central symmetry and thus its vibration performance. Furthermore, the fixture centers the inner core mover first, followed by the outer shell, facilitating the positioning of the inner core mover within the shell without requiring consideration of the available operating space. Finally, a drive ejector ejects the inner core mover and outer shell together, ensuring they detach from the product mounting base simultaneously, avoiding the problem of easy tearing and damage caused by ejecting only the outer shell.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A welding fixture for a mobile phone vibrator includes a fixture body, a product fixing seat disposed on the top of the fixture body, a centering positioning device corresponding to the product fixing seat, an adjustment device corresponding to the product fixing seat, and an ejection and unloading device corresponding to the product fixing seat; wherein:

[0008] The product mounting base is used to fix the main body of the inner core moving part of the mobile phone vibrator. The product mounting base is provided with a positioning part for positioning the inner core moving part in the front-back direction. The centering positioning device is used to center the inner core moving part and the outer shell of the mobile phone vibrator on the left and right sides of the product mounting base. The adjustment device consists of two devices arranged symmetrically on the side of the product mounting base. The adjustment device includes a limiting mechanism and a pressing mechanism. The limiting mechanism is used to limit the leaf spring of the inner core moving part, and the pressing mechanism is used to press the leaf spring welding plate against the inner wall surface of the outer shell. The ejection and unloading device is used to eject the inner core moving part and the outer shell upward from the product mounting base.

[0009] The working process of the welding fixture for the mobile phone vibrator is as follows:

[0010] Step 1: Place the fixture body on the first drive platform. The first drive platform drives the centering positioning device to open. Then, fix the inner core moving part on the product fixing seat. Next, remove the fixture body from the first drive platform. The centering positioning device closes and centers the inner core moving part on the product fixing seat.

[0011] Step 2: Drive the limiting mechanism to limit the leaf spring, then place the fixture body on the second drive platform. The second drive platform drives the centering positioning device to leave the inner core mover. Then, put the outer shell on the inner core mover. Then, remove the fixture body from the second drive platform. The centering positioning device returns to its closed position and centers the outer shell on the left and right outside the inner core mover.

[0012] Step 3: Drive the clamping mechanism to press the leaf spring welding plate against the inner wall of the outer shell, so that the outer shell is centered and positioned outside the inner core mover. Then, weld the leaf spring welding plate and the outer shell together. After welding is completed, reset the clamping mechanism and move away from the leaf spring welding plate.

[0013] Step four: Place the fixture body on the second drive platform. The second drive platform drives the centering positioning device to leave the outer shell, and then drives the ejection and unloading device to eject the inner core mover and the outer shell together.

[0014] As a preferred embodiment, the top of the fixture body is recessed into a first mounting groove, the product fixing seat is fixed in the first mounting groove, and the product fixing seat is provided with a magnet for adsorbing and fixing the inner core mover. The inner core mover is fixed by magnetic connection, which is easy to disassemble and assemble, and at the same time, it is convenient to adjust the position of the inner core mover on the product fixing seat.

[0015] As a preferred embodiment, the centering positioning device includes a first slider and a second slider, which can move relative to and towards each other. The top of the first slider and the second slider are each provided with a first pressing member.

Both the first slider and the second slider are provided with guide components that match the guide surface.

[0017] A first return spring is sandwiched between the first slider and the second slider. When the centering positioning device is in the open state, it drives the movable part to move upward, so that the first slider and the second slider move towards each other under the action of the first return spring and the cooperation of the guide surface and the guide part.

[0018] A second return spring is provided between the top of the movable part and the fixture body. When the centering positioning device is closed, the movable part moves downward under the action of the second return spring, so that the first slider and the second slider move relative to each other under the cooperation of the guide surface and the guide member.

[0019] As a preferred embodiment, the limiting mechanism includes a first limiting component and a second limiting component. The first limiting component includes a first sliding member slidably connected to the fixture body and a baffle connected to the first sliding member.

A first magnetic suction member is provided on the fixing block. The pushing part can be attracted and fixed to the first magnetic suction member. A third return spring is also provided between the pushing part and the fixing block. The third return spring can drive the first sliding member to move towards the opening end of the leaf spring, thereby causing the baffle to block against the opening of the leaf spring. The first rotating member is rotatably connected to the fourth mounting groove. The fourth mounting groove is provided with a second magnetic suction member and a third magnetic suction member respectively corresponding to the two ends of the first rotating member. When the first rotating member rotates to be attracted and fixed to the second magnetic suction member, the limiting pin rotates to leave the gap of the leaf spring. When the first rotating member rotates to be attracted and fixed to the third magnetic suction member, the limiting pin rotates to be inserted into the gap of the leaf spring away from the opening end.

[0021] As a preferred embodiment, the clamping mechanism includes a second sliding member, a third sliding member, and a second rotating member. The second sliding member and the third sliding member are slidably connected to the fixture body. The second sliding member and the third sliding member are respectively provided with a second pressing member and a third pressing member.

[0022] A fourth return spring is provided between the second sliding member and the fixture body, and between the third sliding member and the fixture body. The fourth return spring can drive the second pressing member and the third pressing member to press against both ends of the leaf spring welding plate respectively. The second rotating member can be driven to rotate and, through the first driving part and the second driving part, drive the second pressing member and the third pressing member to overcome the elastic force of the fourth return spring and leave the leaf spring welding plate.

[0023] As a preferred embodiment, the fixture body is provided with two guide rods arranged vertically at a distance. Correspondingly, the second and third sliding members are each provided with two guide grooves corresponding to the two guide rods. The second and third sliding members are slidably connected to the fixture body through the cooperation of the guide grooves and guide rods. The fixture body is rotatably connected to a rotating rod. The second rotating member is disposed at one end of the rotating rod. The first and second driving parts are both disposed on the rotating rod. The second rotating member has a first limiting surface and a second limiting surface. Correspondingly, a rotation limiting member is provided on the side of the fixture body for the first limiting surface and the second limiting surface to abut against. When the first limiting surface abuts against the rotation limiting member, the second and third pressing members are both removed from the leaf spring welding plate. When the second limiting surface abuts against the rotation limiting member, the second and third pressing members abut against the leaf spring welding plate.

[0024] As a preferred embodiment, the ejector feeding device includes a first ejector pin, a second ejector pin, and a product release handle for driving the first and second ejector pins to rise and fall. The first ejector pin is used to eject the inner core moving part, and the second ejector pin is used to eject the outer shell.

[0025] As a preferred embodiment, both the first and second ejector pins are mounted on a mounting block. The fixture body is rotatably connected to a swing arm, one end of which rests against the bottom of the mounting block. The product release handle is connected to the other end of the swing arm. A fourth magnetic element is provided at the end of the product release handle near the fixture body. The product release handle can be attracted and fixed to the fixture body by the fourth magnetic element. A fifth return spring is provided between the mounting block and the fixture body.

[0026] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0027] Its main features include a positioning part on the product mounting base for positioning the inner core mover in the front-to-back direction, a centering positioning device for centering the inner core mover and the outer shell left and right, and a clamping mechanism for centering the outer shell front and back. This ensures that the inner core mover is accurately placed in the outer shell, guaranteeing the central symmetry of the inner core mover inside the shell, thereby ensuring the vibration performance of the inner core mover. Furthermore, the positioning process first centers the inner core mover and then the outer shell, facilitating the positioning operation of the inner core mover within the shell without needing to consider the operable space inside the shell. Additionally, the drive ejection and unloading device ejects the inner core mover and the outer shell together, ensuring that the inner core mover and the outer shell detach from the product mounting base together, avoiding the problem of easy tearing and damage caused by ejecting only the outer shell.

[0069] First, it should be noted that in the description of this invention, the terms "upper," "lower," "left," "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0070] Please refer to Figures 1 to 8 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a fixture body 10, a product fixing seat 20 disposed on the top of the fixture body 10, a centering positioning device 30 disposed corresponding to the product fixing seat 20, an adjustment device 40 disposed corresponding to the product fixing seat 20, and an ejection and unloading device 50 disposed corresponding to the product fixing seat 20.

[0071] The fixture body 10 includes a bottom wall 11, a left side wall 12 and a right side wall 13 disposed at both ends of the bottom wall 11, and a top wall 14 disposed on the top of the left side wall 12 and the right side wall 13. The bottom wall 11, the left side wall 12, the right side wall 13 and the top wall 14 together form a receiving groove 101.

[0072] See Figure 1 and Figure 5 As shown, the product mounting base 20 is used to fix the main body of the inner core moving part of the mobile phone vibrator. Specifically, the top of the top wall 14 is recessed downwards to form a first mounting groove 102, and the product mounting base 20 is fixed in the first mounting groove 102. The product mounting base 20 is provided with magnets for attracting and fixing the inner core moving part. The product mounting base 20 is fixed in the first mounting groove 102 by screws. There are four magnets arranged in a square, and the four magnets are located on the outer periphery of the screws. The magnets are embedded in the product mounting base 20, and the inner core moving part is fixed by magnetic attraction, which is easy to disassemble and assemble. This facilitates the adjustment of the position of the inner core mover on the product fixing seat 20; and the product fixing seat 20 is provided with a positioning part 21 for positioning the front and rear direction of the inner core mover. When the inner core mover is adsorbed and fixed on the product fixing seat 20, the positioning part 21 can directly ensure the accuracy of the front and rear direction of the inner core mover; wherein, the mobile phone vibrator includes an inner core mover and a shell disposed outside the inner core mover. The inner core mover includes a main body and leaf springs disposed at opposite ends of the main body. The leaf springs are U-shaped. One end of the leaf spring is connected to the main body, and the other end of the leaf spring is connected to a leaf spring welding plate for welding to the inner wall surface of the shell.

[0073] See Figures 1 to 3 As shown, the centering positioning device 30 is used to center the inner core moving part and the outer shell of the mobile phone vibrator on the left and right sides of the product fixing base 20. Specifically, the centering positioning device 30 includes a first slider 31 and a second slider 32. The first slider 31 and the second slider 32 are both located in the receiving groove 101. The first slider 31 and the second slider 32 can move relative to each other and towards each other. The top of the first slider 31 and the second slider 32 are provided with a first pressing member 301. The first pressing member 301 is provided with two arranged side by side. The first pressing member 301 is a pin. The first slider 31 and the second slider 32 center the inner core moving part and the outer shell on the left and right sides of the product fixing base 20 through the first pressing member 301.

[0074] The first slider 31 and the second slider 32 are both slidably connected to the fixture body 10. The fixture body 10 is provided with two guide rods 15 arranged side by side, that is, the two guide rods 15 are provided through the left side wall 12 and the right side wall 13. The first slider 31 and the second slider 32 are slidably connected to the two guide rods 15. The arrangement of the two guide rods 15 makes the sliding of the first slider 31 and the second slider 32 more stable. The first slider 31 and the second slider 32 are provided with a second mounting groove 302 that runs vertically through the second mounting groove 302. A movable part 33 is provided in the second mounting groove 302 that can move vertically. The movable part 33 is located between the two guide rods 15. The movable part 33 is provided with a guide surface 303 for driving the first slider 31 and the second slider 32 to slide. The first slider 31 and the second slider 32 are both provided with guide parts 304 that match the guide surface 303.

[0075] A first return spring 34 is sandwiched between the first slider 31 and the second slider 32. The first return spring 34 is sleeved on the outer periphery of the guide rod 15. When the centering positioning device 30 is in the open state, it drives the movable part 33 to move upward, so that the first slider 31 and the second slider 32 move towards each other under the action of the first return spring 34 and the cooperation of the guide surface 303 and the guide part 304.

[0076] A second return spring 35 is provided between the top of the movable part 33 and the fixture body 10. The second return spring 35 is sandwiched between the top of the movable part 33 and the bottom of the top wall 14. When the centering positioning device 30 is closed, the movable part 33 moves downward under the action of the second return spring 35, so that the first slider 31 and the second slider 32 move relative to each other under the cooperation of the guide surface 303 and the guide member 304. The guide surface 303 consists of two symmetrically arranged guide surfaces. The guide member 304 is a roller. The roller is rotatably connected to the corresponding first slider 31 and second slider 32 and is located in the second mounting groove 302. The movable part 33 is provided with two drive rods 305 that pass through the upper and lower ends of the movable part 33. The two drive rods 305 are located on the side of the corresponding guide surface 303. The drive rods 305 are lifted by the first drive platform and the second drive platform, thereby driving the movable part 33 to move up and down.

[0077] See Figures 5 to 8 As shown, there are two adjustment devices 40 located on the side of the product fixing base 20. The two adjustment devices 40 are arranged in a centrally symmetrical manner. Each adjustment device 40 includes a limiting mechanism 41 and a pressing mechanism 42. The limiting mechanism 41 is used to limit the leaf spring of the inner core mover.

The first limiting component 411 includes a first sliding member 401 slidably connected to the fixture body 10 and a baffle 402 connected to the first sliding member 401. The first sliding member 401 can drive the baffle 402 to abut against the open end of the leaf spring. The second limiting component 412 includes a first rotating member 403 rotatably connected to the fixture body 10 and a limiting pin 404 connected to the first rotating member 403. The first rotating member 403 can drive the limiting pin 404 to rotate to a gap that is inserted into the leaf spring away from the open end. The movement of the leaf spring is restricted by the cooperation of the baffle 402 and the limiting pin 404.

[0079] The top of the fixture body 10 is recessed with a third mounting groove 103 and a fourth mounting groove 104. A fixing block 413 is provided in the third mounting groove 103. The first sliding member 401 is slidably connected to the third mounting groove 103. The fixture body 10 is also provided with an anti-detachment member 414 to prevent the first sliding member 401 from detaching from the third mounting groove 103. The first sliding member 401 is provided with a pushing part 405. The movement of the pushing part 405 is restricted between the anti-detachment member 414 and the fixing block 413. A first magnetic suction member 415 is provided on the fixing block 413. The pushing part 405 can be attracted and fixed to the first magnetic suction member 415. A third return spring 416 is also provided, which can drive the first sliding member 401 to move toward the open end of the leaf spring, thereby causing the baffle 402 to abut against the opening of the leaf spring. The first rotating member 403 is rotatably connected in the fourth mounting groove 104. The fourth mounting groove 104 is provided with a second magnetic member 417 and a third magnetic member 418 respectively corresponding to the two ends of the first rotating member 403. When the first rotating member 403 rotates to be attracted and fixed to the second magnetic member 417, the limiting pin 404 rotates to leave the gap of the leaf spring. When the first rotating member 403 rotates to be attracted and fixed to the third magnetic member 418, the limiting pin 404 rotates to be inserted into the gap of the leaf spring away from the open end.

[0080] See Figure 1 , Figure 5 and Figure 6 As shown, the clamping mechanism 42 is used to press the leaf spring welding plate against the inner wall surface of the outer shell. The clamping mechanism 42 includes a second sliding member 421, a third sliding member 422, and a second rotating member 423.

The second rotating member 423 is respectively provided with a first driving part 408 and a second driving part 409 corresponding to the second pressing member 406 and the third pressing member 407.

[0081] Specifically, a fourth return spring 424 is provided between the second sliding member 421 and the fixture body 10, and between the third sliding member 422 and the fixture body 10. The fourth return spring 424 can drive the second pressing member 406 and the third pressing member 407 to press against the two ends of the leaf spring welding plate respectively. The second rotating member 423 can rotate and drive the second pressing member 406 and the third pressing member 407 to overcome the elastic force of the fourth return spring 424 and leave the leaf spring welding plate through the first driving part 408 and the second driving part 409.

[0082] The fixture body 10 is provided with two guide rods 16 arranged vertically at a distance from top to bottom.

Correspondingly, the second sliding member 421 and the third sliding member 422 are each provided with two guide grooves 425 corresponding to the two guide rods 16. The second sliding member 421 and the third sliding member 422 are slidably connected to the fixture body 10 through the cooperation of the guide grooves 425 and the guide rods 16. The fixture body 10 is rotatably connected with a rotating rod 17, that is, the rotating rod 17 passes through the left side wall 12 and the right side wall 13. The second rotating member 423 is disposed at one end of the rotating rod 17. The first driving part 408 and the second driving part 409 both pass through the rotating rod 17. The second rotating member 423 has a first limiting surface 42. 6. Correspondingly, the jig body 10 is provided with a rotation limiting member 18 for the first limiting surface 426 and the second limiting surface 427 to abut against. When the first limiting surface 426 abuts against the rotation limiting member 18, the second pressing member 406 and the third pressing member 407 both move away from the leaf spring welding plate. When the second limiting surface 427 abuts against the rotation limiting member 18, the second pressing member 406 and the third pressing member 407 both press against the leaf spring welding plate. Furthermore, the top wall 14 is provided with a clearance position for the second sliding member 421, the third sliding member 422, the first driving part 408, and the second driving part 409 to avoid each other. The two second rotating members 423 can both be located beside the left side wall 12, or the two second rotating members 423 can be located beside the left side wall 12 and the right side wall 13, respectively.

[0083] See Figure 1 , Figure 4 and Figure 6 As shown, the ejector feeding device 50 is used to eject the inner core moving part together with the outer shell upward from the product fixing seat 20. The ejector feeding device 50 includes a first ejector pin 51, a second ejector pin 52, and a product release handle 53 for driving the first ejector pin 51 and the second ejector pin 52 to rise and fall.

The product release handle 53 can be magnetically attached to the fixture body 10 via the fourth magnetic element 56. A fifth return spring 57 is provided between the mounting block 54 and the fixture body 10. When the first ejector pin 51 and the second ejector pin 52 are ejected, the product is driven to leave the fixture body 10 by the fourth magnetic suction member 56 on the handle 53, so that the swing rod 55 drives the mounting block 54 to rise, thereby driving the first ejector pin 51 and the second ejector pin 52 to be ejected. When the first ejector pin 51 and the second ejector pin 52 are reset, the fifth return spring 57 drives the mounting block 54 to fall, thereby driving the product to be attached and fixed to the fixture body 10 by the fourth magnetic suction member 56 on the handle 53, thus realizing automatic reset.

[0085] The swing arm 55 consists of two arms located at the front and rear ends of the product detachment handle 53. The first magnetic component 415, the second magnetic component 417, the third magnetic component 418, and the fourth magnetic component 56 are all magnets.

[0086] The working process of this embodiment is described in detail below:

[0087] Step 1: Place the fixture body 10 on the first drive platform. The first drive platform drives the centering positioning device 30 to open. That is, the first drive platform drives the drive rod 305 to rise, which in turn drives the two first pressing parts 301 on both sides of the product fixing seat 20 to open. Then, fix the inner core moving part on the product fixing seat 20. Next, remove the fixture body 10 from the first drive platform. The centering positioning device 30 returns to its original position and closes, centering the inner core moving part on the product fixing seat 20. That is, under the drive of the second return spring 35, the moving part 33 drives the drive rod 305 to descend, causing the two first pressing parts 301 on both sides of the product fixing seat 20 to move closer together.

[0088] Step 2: Drive the limiting mechanism 41 to limit the leaf spring, that is, drive the pushing part 405 to disengage from the fixed block 413 so that the third return spring 416 drives the first sliding member 401 to move toward the opening end of the leaf spring, thereby driving the baffle 402 to block the opening of the leaf spring. Drive the first rotating member 403 to rotate so that the limiting pin 404 rotates to be inserted into the gap away from the opening end of the leaf spring. Then, place the fixture body 10 on the second driving platform. The second driving platform drives the centering positioning device 30 to leave the inner core moving part. Then, put the outer shell on the inner core moving part. Then, remove the fixture body 10 from the second driving platform. The centering positioning device 30 closes and centers the outer shell on the left and right outside the inner core moving part.

[0089] Step 3: Drive the clamping mechanism 42 to press the leaf spring welding plate against the inner wall of the outer shell. That is, drive the second rotating member 423 to rotate so that the first driving part 408 and the second driving part 409 move away from the corresponding second sliding member 421 and the third sliding member 422. This allows the second pressing member 406 and the third pressing member 407 to press against the two ends of the leaf spring welding plate under the drive of the fourth return spring 424. This makes the outer shell centered and positioned outside the inner core mover. Then, place the fixture body 10 into the welding equipment to weld the leaf spring welding plate and the outer shell together. The welding can be laser welding. After the welding is completed, reset the clamping mechanism 42 and move away from the leaf spring welding plate.

[0090] Step four: Place the fixture body 10 on the second drive platform. The second drive platform drives the centering positioning device 30 to leave the outer shell, and then drives the ejector feeding device 50 to eject the inner core moving part and the outer shell together. That is, drive the product to detach from the handle 53 and rotate away from the fixture body 10. Then, through the swing rod 55, drive the mounting block 54 to rise, so as to drive the first ejector pin 51 and the second ejector pin 52 to protrude from the top of the top wall 14 and eject the inner core moving part and the outer shell together. Finally, drive the limit pin 404 and the baffle 402 to reset.

[0091] The key design focus of this invention is:

[0092] Its main features include a positioning part on the product mounting base for positioning the inner core mover in the front-to-back direction, a centering positioning device for centering the inner core mover and the outer shell left and right, and a clamping mechanism for centering the outer shell front and back. This ensures that the inner core mover is accurately placed in the outer shell, guaranteeing the central symmetry of the inner core mover inside the shell, thereby ensuring the vibration performance of the inner core mover. Furthermore, the positioning process first centers the inner core mover and then the outer shell, facilitating the positioning operation of the inner core mover within the shell without needing to consider the operable space inside the shell. Additionally, the drive ejection and unloading device ejects the inner core mover and the outer shell together, ensuring that the inner core mover and the outer shell detach from the product mounting base together, avoiding the problem of easy tearing and damage caused by ejecting only the outer shell.

[0093] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
