Description

TECHNICAL FIELD

[0001] The application relates to the technical field of dispensing machines, in particular to a dispensing machine for electronic product production. BACKGROUND

[0002] The dispensing machine is an automatic machine specially used for controlling fluid, also known as a glue applying machine, a glue dropping machine, a glue dispensing machine, a glue filling machine and the like. The dispensing tool is a kind of auxiliary tool specially used in the dispensing process. In the production of electronic products, the dispensing tool is usually used for dispensing and fixing components such as touch screens and circuit boards, so as to facilitate subsequent packaging and assembly.

[0003] As disclosed in the Chinese patent with the application number CN202122928800.8, a dispensing mechanism with spacing adjustment function is disclosed, which comprises an XYZ driving module, and a dispensing adjustment module capable of manually adjusting the spacing of dispensing valves is arranged on the XYZ driving module. The dispensing adjustment module capable of manually adjusting the spacing between two dispensing valves is adopted, and the distance between each dispensing valve can be adjusted by a locking screw. This adjustment mode can be set according to the actual dispensing position of the product, and the design is more flexible. The utility model also has the advantages of simple structure and convenient adjustment. However, since the spacing adjustment between the dispensing valves is completed by manual mode, the adjustment is not flexible enough, and the spacing between the dispensing valves cannot be adjusted synchronously.

[0004] As disclosed in the Chinese patent with the application number CN201921237710.0, a dispensing claw with adjustable spacing between glue claws for plywood dispensing machine is disclosed, which comprises a protection mechanism, a connecting rod, a glue claw and an extension mechanism. The connecting rod is connected to one side of the protection mechanism, and the glue claw is installed at one end of the connecting rod. A fixed bolt and a sliding groove are sequentially arranged on one side of the protection mechanism, and a pressing bolt is arranged on one side of the sliding groove. An extension mechanism is arranged in the protection mechanism. The dispensing claw with adjustable spacing between glue claws for the plywood dispensing machine can move all connecting rods through the extension or contraction of the extension mechanism, and then move all glue claws, so as to realize the overall adjustment of the glue claws and improve the working efficiency of the glue claw adjustment. Since the glue claws are fixedly installed on the connecting rod mechanism, the connecting rod mechanism is controlled by the precise extension mechanism. The extension mechanism inevitably causes a certain hysteresis effect of the connecting rod mechanism during the extension or contraction process. Therefore, when the connecting rod mechanism is used to accurately control the position of the glue claw, the glue claw will shake to a certain extent, which will affect the stable dispensing of the glue claw. SUMMARY

[0005] To address the aforementioned problems, this invention proposes a dispensing machine for electronic product manufacturing. This dispensing machine can synchronously adjust the spacing between each dispensing head by controlling the movement of each slider, thus meeting the dispensing needs of different types of circuit boards. The trapezoidal rubber ribs used for locking the dispensing head after positioning are flexibly connected to the clamping block. When the linkage mechanism is accidentally activated, the trapezoidal rubber ribs will not restrict the connecting plate, thereby improving the service life of the linkage mechanism on the dispensing machine.

[0006] To achieve the purpose of this invention, the invention is achieved through the following technical solution: a dispensing machine for electronic product manufacturing, comprising a dispensing table and a lifting device, a slide seat at the bottom of the dispensing table, an adjusting block at the top of the slide seat, both the slide seat and the adjusting block being slidably connected to the dispensing table, and a plurality of dispensing heads being provided between the adjusting block and the slide seat;

[0007] The lifting device includes an electric push rod A and a lifting plate. The mounting end of the electric push rod A is fixedly connected to the adjusting block, and the output end of the electric push rod A is fixedly connected to the back of the lifting plate.

[0008] Multiple sliders are slidably arranged on the front of the lifting plate. Each slider is evenly distributed along the length of the lifting plate. Connecting plates are detachably connected to the upper and lower ends of the sliders. Each connecting plate at the bottom is detachably connected to each dispensing head. The lifting plate is equipped with a linkage mechanism for synchronously adjusting the distance between each slider. The lifting plate is also equipped with a damping positioning device for limiting the sliding of the connecting plates.

[0009] The damping positioning device includes a clamping block, an opening and closing assembly, and two sets of trapezoidal rubber ribs. The clamping block is detachably connected to the side of the connecting plate away from the slider. A trapezoidal clamping groove is provided on the side of the clamping block away from the connecting plate. Each trapezoidal clamping groove is matched with the two sets of trapezoidal rubber ribs. The opening and closing assembly is placed at the upper and lower ends of the lifting plate and is used to push the trapezoidal rubber ribs into the trapezoidal clamping grooves and apply pressure.

[0010] A further improvement is that a guide rail is laid on the front of the lifting plate, the guide rail is fixedly connected to the lifting plate, and each slider is slidably connected to the guide rail.

[0011] A further improvement is that the linkage mechanism includes multiple cross-arranged shear bars, the intersection of which is pivotally connected by a pivot, which is pivotally connected to the side of the slider away from the lifting plate. One of the shear bars is provided with an electric push rod B for pushing the opening and closing of each shear bar, and the output end of the electric push rod B is hinged to the shear bar.

[0012] A further improvement is made in that: the opening and closing assembly includes two sets of adjusting plates and two sets of screws. The adjusting plates are fixedly connected to the side of the trapezoidal rubber strip away from the clamping block. The two sets of screws are rotatably connected to the upper and lower ends of the lifting plate, respectively. The two sets of screws pass through the two sets of adjusting plates. The adjusting plates and screws are threadedly engaged. The threads on the outer sides of the two sets of adjusting plates rotate in opposite directions. The back of the lifting plate is provided with a driving component for controlling the synchronous rotation of the two sets of screws. The lifting plate is provided with a limiting component for restricting the up and down movement of the adjusting plates.

[0013] A further improvement is that the driving component includes a transmission box, which is fixedly connected to the back of the lifting plate. The transmission box contains two bevel gears and a transmission shaft. The transmission shaft is fixedly connected to two sets of screws. One bevel gear is fixedly connected to the outside of the screw, and the other bevel gear is fixedly connected to the output end of the motor located on the outside of the transmission box.

[0014] A further improvement is that the limiting component includes at least two sets of limiting rods, which are fixedly connected to the upper and lower ends of the lifting plate, respectively. The two sets of limiting rods pass through the two sets of adjusting plates, and the adjusting plates are slidably connected to the limiting rods. A nut is provided at the end of the limiting rod away from the lifting plate to prevent the adjusting plate from separating from the limiting rod.

[0015] A further improvement is that: a protective cover is provided on the front of the lifting plate, the linkage mechanism is placed inside the protective cover, and bolt plates are fixedly connected to the left and right sides of the protective cover. Fixing bolts are mounted on the bolt plates, and the fixing bolts are threadedly connected to bolt holes opened on the outside of the lifting plate. The mounting end of the electric push rod B is hinged to the hinge seat fixed on the outside of the protective cover.

[0016] A further improvement is that: a glue head holder is fixedly connected to the side of the glue head facing the lifting plate, the glue head holder has a groove, the groove engages with the connecting plate, and an installation bolt is threaded to the outer side of the glue head holder, the installation bolt passes into the groove and is threaded to a bolt hole on the outer side of the connecting plate.

[0017] A further improvement is that: the connecting plate and the clamping block are provided with an insert and a slot on their opposite sides, the insert is fixedly connected to the connecting plate, the slot is opened on the outside of the clamping block and cooperates with the insert, the insert has a threaded hole on the outside, and a positioning bolt B is threadedly connected to the outside of the clamping block. The positioning bolt B passes into the slot and is threadedly connected to the threaded hole.

[0018] A further improvement is that: the connecting plate has a groove on the side facing the slider, the slider engages with the groove, and a positioning bolt A is threadedly connected to the outside of the connecting plate. The positioning bolt A passes into the groove and is threadedly connected to the positioning hole on the outside of the slider.

[0019] The beneficial effects of this invention are as follows: The linkage mechanism of this invention can simultaneously adjust the spacing between each dispensing head by adjusting the distance between each slider, thereby meeting the dispensing needs of different circuit board styles and offering high flexibility. During and after spacing adjustment, the opening and closing assembly simultaneously pushes two sets of trapezoidal rubber ribs into the trapezoidal grooves on the clamping block and applies pressure, the force of which is adjustable. Through the damping between the trapezoidal rubber ribs and the clamping block, the secondary movement of the connecting plate is limited, improving the dispensing and positioning stability of the dispensing head. Since the trapezoidal rubber ribs and the clamping block are connected in a flexible manner, when the linkage mechanism is accidentally activated, the trapezoidal rubber ribs will not restrict the connecting plate fixed at the upper and lower ends of the slider, thereby protecting the linkage mechanism and improving its service life.

Detailed Implementation

[0027] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0028] according to Figures 1-6As shown, this embodiment proposes a dispensing machine for electronic product manufacturing, including a dispensing table 1 and a lifting device. The bottom of the dispensing table 1 is provided with a slide 2, and the top of the slide 2 is provided with an adjusting block 3. The slide 2 and the adjusting block 3 are slidably connected to the dispensing table 1, and a plurality of dispensing heads 5 are provided between the adjusting block 3 and the slide 2.

[0029] The lifting device includes an electric push rod A4 and a lifting plate 6. The mounting end of the electric push rod A4 is fixedly connected to the adjusting block 3, and the output end of the electric push rod A4 is fixedly connected to the back of the lifting plate 6.

[0030] During dispensing, the dispensing fixture is placed on the slide block 2, the adjusting block 3 adjusts the electric push rod A4 to the X-axis position, the dispensing head 5 is arranged on the front of the lifting plate 6, and the electric push rod A4 pushes each dispensing head 5 to fall synchronously through the lifting plate 6 to perform the dispensing operation.

[0031] Multiple sliders 19 are slidably arranged on the front of the lifting plate 6. Each slider 19 is evenly distributed along the length of the lifting plate 6. The upper and lower ends of the sliders 19 are detachably connected to connecting plates 8. Each connecting plate 8 located below is detachably connected to each dispensing head 5. The lifting plate 6 is provided with a linkage mechanism for synchronously adjusting the distance between each slider 19. The lifting plate 6 is provided with a damping positioning device for limiting the sliding of the connecting plates 8.

[0032] Each dispensing head 5 is fixed to each slider 19 on the front of the lifting plate 6 via each connecting plate 8. The linkage mechanism can adjust the distance between each dispensing head 5 synchronously by adjusting the distance between each slider 19, thereby meeting the dispensing needs of different circuit boards and providing high flexibility.

[0033] The damping positioning device includes a clamping block 21, an opening and closing assembly, and two sets of trapezoidal rubber ribs 15. The clamping block 21 is detachably connected to the side of the connecting plate 8 away from the slider 19. A trapezoidal clamping groove 22 is provided on the side of the clamping block 21 away from the connecting plate 8. Each trapezoidal clamping groove 22 is matched with the two sets of trapezoidal rubber ribs 15. The opening and closing assembly is placed at the upper and lower ends of the lifting plate 6 and is used to push the trapezoidal rubber ribs 15 into the trapezoidal clamping groove 22 and apply pressure.

[0034] During and after spacing adjustment, the opening and closing assembly simultaneously pushes the two sets of trapezoidal rubber ribs 15 into the trapezoidal grooves 22 on the clamping block 21, applying pressure that is adjustable. The damping between the trapezoidal rubber ribs 15 and the clamping block 21 restricts secondary movement of the connecting plate 8, improving the dispensing and positioning stability of the dispensing head 5. Because the trapezoidal rubber ribs 15 and the clamping block 21 are flexibly connected, when the linkage mechanism is accidentally activated, the trapezoidal rubber ribs 15 will not completely restrict the connecting plate 8 fixed to the upper and lower ends of the slider 19, thus protecting the linkage mechanism and extending its service life.

[0035] It is worth explaining in detail that a guide rail 20 is laid on the front of the lifting plate 6, and the guide rail 20 is fixedly connected to the lifting plate 6. Each slider 19 is slidably connected to the guide rail 20. The guide rail 20 fixed to the front of the lifting plate 6 is used to limit the slider 19 and ensure the stability of the spacing adjustment of the dispensing head 5.

[0036] Regarding linkage mechanisms:

[0037] The linkage mechanism includes multiple cross-arranged shear bars 23. The intersection of each shear bar 23 is pivotally connected by a pivot 24. The pivot 24 is rotatably connected to the side of the slider 19 away from the lifting plate 6. One of the shear bars 23 is provided with an electric push rod B11 for pushing each shear bar 23 to open and close. The output end of the electric push rod B11 is hinged to the shear bar 23.

[0038] Each slider 19 is positioned at the intersection of each scissor bar 23 and connected to the scissor bars 23 via a pivot 24. When the electric push rod B11 pushes one of the scissor bars 23 on the linkage mechanism to unfold, all the scissor bars 23 connected to that scissor bar 23 will also unfold, increasing the distance between pivots 24 and the distance between sliders 19. When the scissor bar 23 is pulled, the distance between pivots 24 and the distance between sliders 19 will decrease.

[0039] Regarding the opening and closing components:

[0040] The opening and closing assembly includes two sets of adjusting plates 14 and two sets of screws 17. The adjusting plates 14 are fixedly connected to the side of the trapezoidal rubber rib 15 away from the clamping block 21. The two sets of screws 17 are rotatably connected to the upper and lower ends of the lifting plate 6, respectively. The two sets of screws 17 pass through the two sets of adjusting plates 14, and the adjusting plates 14 and screws 17 are threaded together. The threads on the outer sides of the two sets of adjusting plates 14 rotate in opposite directions. The back of the lifting plate 6 is provided with a drive component for controlling the synchronous rotation of the two sets of screws 17. The lifting plate 6 is provided with a limiting component for restricting the up and down movement of the adjusting plates 14.

[0041] After adjusting the spacing of each dispensing head 5, the drive unit controls the two sets of screws 17 to rotate synchronously. The screws 17 are threadedly engaged with the adjusting plate 14. When the screws 17 rotate, the adjusting plate 14 moves up and down along the screw 17. When the adjusting plate 14 moves closer to the clamping block 21, it pushes the trapezoidal rubber rib 15 into the clamping block 21. The damping between the clamping block 21 and the trapezoidal rubber rib 15 limits the shaking of the connecting plate 8. Because the outer threads of the two sets of screws 17 have different directions of rotation, when the two sets of screws 17 rotate synchronously, the two sets of adjusting plates 14 move synchronously in opposite directions along the screw 17. This bidirectional limiting method further ensures the stable positioning of the slider 19 and the dispensing head 5.

[0042] The rotation of screw 17 is controlled by a drive mechanism. Specifically, the drive mechanism includes a transmission box 16, which is fixedly connected to the back of the lifting plate 6. The transmission box 16 contains two bevel gears and a drive shaft. The drive shaft is fixedly connected to two sets of screws 17. One bevel gear is fixedly connected to the outside of screw 17, and the other bevel gear is fixedly connected to the output end of a motor 18 located on the outside of the transmission box 16. The two bevel gears and the drive shaft are located inside the transmission box 16. Screw 17 drives the two sets of screws 17 to rotate synchronously via the bevel gear transmission. Further details are omitted here.

[0043] To prevent tilting when the two sets of adjusting plates 14 move vertically, the limiting component includes at least two sets of limiting rods 12. The two sets of limiting rods 12 are fixedly connected to the upper and lower ends of the lifting plate 6, respectively. The two sets of limiting rods 12 pass through the two sets of adjusting plates 14, and the adjusting plates 14 are slidably connected to the limiting rods 12. A nut 13 is provided at the end of the limiting rod 12 away from the lifting plate 6 to prevent separation between the adjusting plate 14 and the limiting rod 12. When the adjusting plate 14 moves, it slides along the body of the limiting rod 12. The limiting rod 12, through its cooperation with the adjusting plate 14, limits the adjustment plate 14 from both ends of the plate. The nuts 13 are fixed to the ends of the limiting rods 12 by threaded connections. When removing the adjusting plate 14, each nut 13 is unscrewed from the ends of the limiting rods 12 and the screws 17.

[0044] To protect the slider 19 and linkage mechanism on the lifting plate 6, a protective cover 7 is provided on the front of the lifting plate 6. The linkage mechanism is placed inside the protective cover 7. Bolt plates are fixedly connected to the left and right sides of the protective cover 7, and fixing bolts are mounted on the bolt plates. The fixing bolts are threadedly connected to bolt holes on the outside of the lifting plate 6. The mounting end of the electric push rod B11 is hinged to a hinge seat fixed on the outside of the protective cover 7. The protective cover 7 covers the front of the lifting plate 6 to protect the slider 19, guide rail 20, and linkage mechanism mounted on the lifting plate 6, preventing damage to the transmission components due to collisions between the components on the lifting plate 6 and external objects during the translation of the lifting plate 6, thus improving the safety of the dispensing equipment.

[0045] Please see Figure 4 To facilitate the replacement of the dispensing head 5, in a preferred embodiment, a dispensing head holder 9 is fixedly connected to the side of the dispensing head 5 facing the lifting plate 6. The dispensing head holder 9 has a slot that engages with the connecting plate 8. A mounting bolt is threaded onto the outer side of the dispensing head holder 9, passing through the slot and threadedly connected to a bolt hole on the outer side of the connecting plate 8. The dispensing head 5 is fixed to the connecting plate 8 by a threaded connection. To remove the dispensing head 5, simply unscrew the mounting bolt from the bolt hole on the outer side of the connecting plate 8.

[0046] Please see Figure 6To facilitate the replacement of clamping block 21, in a preferred embodiment, the connecting plate 8 and clamping block 21 have an insert 26 and a slot on their facing sides. The insert 26 is fixedly connected to the connecting plate 8, and the slot is located on the outside of clamping block 21 and engages with the insert 26. A threaded hole is provided on the outside of the insert 26, and a positioning bolt B28 is threadedly connected to the outside of clamping block 21. The positioning bolt B28 passes into the slot and is threadedly connected to the threaded hole. Similarly, clamping block 21 is also fixed to connecting plate 8 by a threaded connection. However, the difference is that during installation, the insert 26 at the end of connecting plate 8 is inserted into the slot on the connecting surface of clamping block 21. By engaging with the slot, the insert 26 improves the structural strength of the connection between clamping block 21 and connecting plate 8 from the inside of clamping block 21.

[0047] To facilitate the replacement of plate 8, in a preferred embodiment, the side of the connecting plate 8 facing the slider 19 has a groove, which engages with the slider 19. A positioning pin A25 is threaded onto the outer side of the connecting plate 8, and the positioning pin A25 passes into the groove and is threaded into the positioning hole 27 on the outer side of the slider 19. Similarly, when removing the connecting plate 8 from the slider 19, the positioning pin A25 on the outer side of the connecting plate 8 can be unscrewed from the positioning hole 27 on the outer side of the motor 18.

[0048] The slider 19, connecting plate 8, clamping block 21 and rubber head holder 9 are all designed as separate units. The separate design makes it easy to replace each component individually and facilitates daily maintenance.

[0049] In this type of dispensing machine for electronic product manufacturing, each dispensing head 5 is fixed to each slider 19 on the front of the lifting plate 6 via a connecting plate 8. The linkage mechanism can synchronously adjust the spacing between each dispensing head 5 by adjusting the distance between each slider 19, thereby meeting the dispensing needs of different circuit boards and offering high flexibility. During and after spacing adjustment, the opening and closing assembly synchronously pushes two sets of trapezoidal rubber ribs 15 into the trapezoidal grooves 22 on the clamping block 21 and applies pressure, which is adjustable. The damping between the trapezoidal rubber ribs 15 and the clamping block 21 restricts secondary movement of the connecting plate 8, improving the dispensing and positioning stability of the dispensing head 5. Since the trapezoidal rubber ribs 15 and the clamping block 21 are connected in a flexible manner, when the linkage mechanism is accidentally activated, the trapezoidal rubber ribs 15 will not restrict the connecting plate 8 fixed at the upper and lower ends of the slider 19, thereby protecting the linkage mechanism and improving its service life.
