Implementation Method

[0035] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the present invention.

[0036] Example 1: A Bluetooth headset automatic glue assembly device, such as Figure 1-Figure 7As shown, it includes a base 1, a main bracket 101, an electric turntable 102, a support rod 103, a mold 104, a loading barrel 106, a feeding guide rod 107, a feeding tension spring 108, a feeding support plate 109, a feeding clamping plate 110, a first connecting rod 111, a second connecting rod 112, a third connecting rod 113, a main connecting rod 114, a return spring 115, a driving feeding mechanism, a clamping mechanism and a bearing mechanism. The main bracket 101 is fixed to the base 1, and the electric turntable 102 is installed on the base 1. The electric turntable 102 is a prior art. The electric turntable 102 can After being powered on, it rotates intermittently. Four groups of support rods 103 are fixed in a circular array on the electric turntable 102. Each group of support rods 103 has two. A mold 104 is installed on the two support rods 103 in each group. Two positioning grooves 105 are symmetrically provided on the mold 104. The earplugs of the earphones can be placed in the positioning grooves 105. Two loading barrels 106 are symmetrically fixed on the main bracket 101. The loading barrel 106 is used to place the rear shell cover. Each loading barrel 106 is symmetrically connected to four feeding guide rods 107 in a sliding manner along the vertical direction. The lower ends of the two adjacent feeding guide rods 107 are fixedly connected to a feeding support plate 109. The feeding guide rods 107 are all sleeved with a feeding tension spring 108. The two ends of the feeding tension spring 108 are fixedly connected to the loading barrel 106 and the feeding support plate 109. The feeding support plate 109 is connected to a feeding splint 110 that slides horizontally. There are four feeding splints 110 in total, and each two feeding splints 110 form a group. The feeding splints 110 are all rotatably connected to a first connecting rod 111. The first connecting rod 111 located on the left and right sides is rotatably connected to a second connecting rod 112. The second connecting rod 113 is rotatably connected to the first connecting rod 111. The rod 112 is connected to the feeding support plate 109 in a horizontal sliding direction, and a return spring 115 is provided on the second connecting rod 112. The two first connecting rods 111 in the middle are rotated together to be connected to the third connecting rod 113. The third connecting rod 113 is also provided with a return spring 115. The second connecting rod 112 and the third connecting rod 113 are fixedly connected to the main connecting rod 114 at one end away from the first connecting rod 111. The main bracket 101 is connected to a driving feeding mechanism, which is used to drive the feeding splint 110 to clamp the rear shell cover and place the rear shell cover on the earphone shell.

[0037] The rear shell covers to be assembled are stacked horizontally in advance and placed in two loading barrels 106. The lowermost rear shell cover will fall on the carrying mechanism. The rear shell cover on the carrying mechanism is located in the clamping range of the feeding clamping plate 110, and the second to last rear shell cover is located in the clamping range of the clamping mechanism; a pair of earphone shells coated with glue to be assembled are placed on the mold 104, and the earplugs of the earphones are located in the positioning groove 105. The electric turntable 102 is controlled to rotate intermittently, each time rotating 90 degrees. When the mold 104 with the earphone shell rotates to the bottom of the loading barrel 106, the electric turntable 102 is turned on. The rotating disk 102 stops rotating, and the clamping mechanism is controlled to clamp the second-to-last rear shell cover first, and then the driving feeding mechanism is started. The driving feeding mechanism will first drive the main connecting rod 114 to move in the direction close to the loading barrel 106. The main connecting rod 114 pushes the first connecting rod 111 to rotate through the second connecting rod 112 and the third connecting rod 113, and compresses the return spring 115. Since the feeding clamping plate 110 is slidably connected to the feeding support plate 109, the two feeding clamping plates 110 in the same group will approach each other and clamp the lowermost rear shell cover, and then drive the feeding. The mechanism drives the main connecting rod 114 to move downward, and the main connecting rod 114 drives the feeding clamping plate 110 and the feeding support plate 109 to move downward through the third connecting rod 113, the second connecting rod 112 and the first connecting rod 111, and stretches the feeding tension spring 108, so that the feeding clamping plate 110 drives the clamped rear shell cover to move downward. When the rear shell cover is about to move onto the earphone shell, the driving feeding mechanism no longer drives the main connecting rod 114 to move in the direction close to the charging barrel 106, and the reset spring 115 pushes the second connecting rod 112 and the third connecting rod 113 to reset, thereby driving The main connecting rod 114 and the first connecting rod 111 are reset, and the first connecting rod 111 drives the feeding splint 110 to loosen the clamping of the rear shell cover, so that the rear shell cover falls on the earphone shell, and then the feeding mechanism is driven to no longer drive the main connecting rod 114 to move downward, and the feeding tension spring 108 drives the feeding support plate 109, the feeding splint 110, the first connecting rod 111, the second connecting rod 112, the third connecting rod 113 and the main connecting rod 114 to reset upward, and then the feeding mechanism is controlled to reset, and the clamping mechanism loosens the clamping of the rear shell cover, and the upper rear shell cover falls downward on the supporting mechanism.

[0038] like Figure 1 、 Figure 4 、 Figure 6 and Figure 8As shown, the driving feeding mechanism includes a clamping block 2, a large electric push rod 202, a translation plate 203, a pressing rod 204, a clamping pressure block 205, a pressure block spring 2051 and a blocking plate 206. The clamping block 2 is fixedly connected to the main connecting rod 114, and two reset grooves 201 are symmetrically provided on the clamping block 2. The large electric push rod 202 is fixedly installed on the main bracket 101, and the translation plate 203 is fixedly installed on the telescopic axis of the large electric push rod 202. The translation plate 203 and the main bracket 101 are vertically aligned. The sliding connection is in the direction of movement, and two pressing rods 204 are symmetrically fixed on the translation plate 203 for pressing the clamping block 2 to drive it to move downward. The pressing rod 204 is horizontally slidably connected with a clamping pressure block 205 for squeezing the clamping block 2 to drive the feeding clamp 110 to clamp the rear shell cover. A pressure block spring 2051 is provided on the clamping pressure block 205, and a blocking plate 206 is fixed on the main bracket 101. The blocking plate 206 is used to prevent the clamping pressure block 205 from moving away from the clamping block 2.

[0039] When the mold 104 with the earphone shell rotates to the bottom of the charging barrel 106, the large electric push rod 202 is controlled to extend and drive the translation plate 203 to move downward, and the translation plate 203 drives the pressing rod 204 and the clamping block 205 to move downward. Due to the obstruction of the blocking plate 206, the clamping block 205 cannot move in the direction away from the charging barrel 106, so the clamping block 205 can squeeze the clamping block 2 in the direction close to the charging barrel 106, thereby driving the main connecting rod 114 to move synchronously. When the feeding splint 110 clamps the rear shell cover, the pressing rod 204 will contact the top of the clamping block 2, and the pressing rod 204 will drive the main connecting rod 114 downward through the clamping block 2. When the rear shell cover is about to contact the earphone shell, the clamping block 205 disengages from the blocking plate 206, and the main connecting rod 114 resets and drives When the clamping block 205 moves to the top of the clamping block 2, the clamping block 2 is reset.

[0040] like Figure 5 and Figure 9As shown, it also includes a clamping mechanism for limiting the rear shell cover in the loading barrel 106 from falling downward. The clamping mechanism is installed on the loading barrel 106. The clamping mechanism includes a small electric push rod 3 and a clamping plate 301. Two small electric push rods 3 are symmetrically fixedly installed on the loading barrel 106. Two clamping plates 301 are symmetrically slidably connected on the loading barrel 106. The telescopic axis of the small electric push rod 3 is fixedly connected to the clamping plate 301 on the same side.

[0041] The second-to-last rear shell cover is located between the two clamping plates 301. When the rear shell cover needs to be clamped, the small electric push rod 3 is controlled to contract to drive the clamping plates 301 on the same loading barrel 106 to move closer to each other, thereby clamping the rear shell cover to prevent the upper rear shell cover from moving downward during the process of clamping the rear shell cover and conveying it downward. The small electric push rod 3 extends to drive the clamping plates 301 to loosen the clamping of the rear shell cover.

[0042] like Figure 5 and Figure 9 As shown, it also includes a supporting mechanism for supporting the rear shell cover to facilitate clamping of the feeding clamp 110. The supporting mechanism is installed on the loading barrel 106. The supporting mechanism includes a blocking block 4 and a blocking torsion spring 401. Four blocking blocks 4 are symmetrically connected to the loading barrel 106 for rotation, and a blocking torsion spring 401 is connected between the blocking block 4 and the loading barrel 106.

[0043] The bottom rear shell cover will fall on the four stop blocks 4 so that the feeding clamp 110 can clamp it. When the clamping plate 301 clamps the rear shell cover and transports it downward, the rear shell cover will squeeze the stop block 4 downward and store the stop torsion spring 401. When the rear shell cover moves downward and disengages from the stop block 4, the stop torsion spring 401 drives the stop block 4 to reverse and reset.

[0044] Example 2: Based on Example 1, Figure 1-Figure 3 As shown, it also includes a flip blanking mechanism for blanking the assembled earphones, which is connected to the electric turntable 102. The flip blanking mechanism includes a blanking connecting rod 5, a blanking slide 501, a blanking spring 502, a rack 503, a transmission shaft 504, a blanking gear 505 and a blanking pressure plate 506. The supporting rod 103 is fixed with a blanking connecting rod 5, and the two blanking connecting rods 5 on the same side are connected to the blanking slide 501 in a vertical direction. Two unloading springs 502 are symmetrically sleeved on the rod 501, two racks 503 are symmetrically fixed on the unloading slide 501, two transmission shafts 504 are symmetrically fixed on the mold 104, the transmission shafts 504 are rotatably connected to the two support rods 103 on the same side, a unloading gear 505 is fixed on the transmission shaft 504, the unloading gear 505 is engaged with the rack 503, and a unloading pressure plate 506 for driving the unloading slide 501 to move downward is fixed on the translation plate 203.

[0045] The downward movement of the translation plate 203 will drive the blanking pressure plate 506 to move downward and compress the blanking spring 502. The lower pressure plate will drive the rack 503 to move downward through the blanking slide 501. The rack 503 drives the blanking gear 505 to rotate, thereby turning the mold 104 one hundred and eighty degrees, causing the assembled earphones to fall downward and be discharged. When the translation plate 203 drives the blanking pressure plate 506 to reset upward, the blanking spring 502 pushes the blanking slide 501 to reset upward, thereby driving the mold 104 to reverse one hundred and eighty degrees and reset through the cooperation of the rack 503 and the blanking gear 505.

[0046] like Figure 3 and Figure 10 As shown, a stop assembly is also included for preventing the transmission shaft 504 from rotating at will. The stop assembly is installed on the transmission shaft 504. The stop assembly includes a clamping block 6 and a small spring 601. There are two clamping blocks 6 symmetrically connected to the transmission shaft 504 in a vertical sliding direction. A small spring 601 is sleeved on the clamping block 6. When the clamping block 6 slides into the transmission shaft 504, the small spring 601 is compressed. Two grooves are provided on the support rod 103 for easy insertion of the clamping block 6.

[0047] Under the action of the small spring 601, the block 6 can be stuck in the groove of the support rod 103, which plays the role of fixing the transmission shaft 504 and preventing the mold 104 from rotating when it is in other workstations. When the rack 503 and the gear drive the transmission shaft 504 to rotate, the block 6 is squeezed and shrinks into the transmission shaft 504, and compresses the small spring 601. After rotating one hundred and eighty degrees, the small spring 601 pushes the block 6 to be stuck in the groove on the support rod 103 again.

[0048] like Figure 8 、 Figure 11 and Figure 12As shown, it also includes a gluing mechanism for applying glue to the earphone shell, which is connected to the translation plate 203. The gluing mechanism includes a gluing bracket 7, a fixing bracket 701, a gluing device 702, a motor 703, a small gear 704, a gluing ring 705, a large gear 706, a retracting rod 707, a gluing spring 7071, a gluing connecting rod 708, an annular guide bracket 709 and an annular guide block 710. The gluing bracket 7 is fixedly connected to the translation plate 203, and the motor 703 is fixedly mounted on the gluing bracket 7. The small gear 704 is fixedly connected to the output shaft of the motor 703. The gluing ring 705 is rotatably connected to the gluing bracket 7. The large gear 706 is fixedly connected to the gluing ring 705. The large gear 706 and the small gear 70 4 is engaged, a retraction rod 707 is fixed to the eccentric position of the glue applying ring 705, a glue applying spring 7071 is sleeved on the retraction rod 707, a glue applying connecting rod 708 is connected to the retraction rod 707 in a horizontal sliding direction, an annular guide frame 709 and an annular guide block 710 are fixed to the glue applying bracket 7, the annular guide block 710 is located in the middle of the annular guide frame 709, and an O-shaped slide is formed between the annular guide block 710 and the annular guide frame 709. The slide has the same shape and size as the position where the earphone needs to be glued, and the glue applying connecting rod 708 is located in the slide. The lower end of the glue applying connecting rod 708 is fixed to the fixing frame 701, and two glue applicators 702 are installed on the fixing frame 701. The glue applicator 702 is a device for applying glue in the prior art.

[0049] Below the gluing bracket 7 is the gluing station. The worker places the earphone shell that needs to be glued in the mold 104 below the gluing bracket 7. When the translation plate 203 moves downward, it will drive the gluing bracket 7 and the structure on it to move downward. When the large electric push rod 202 is fully extended and drives the translation plate 203 to move to the bottom, the glue discharge position of the lower end of the glue applicator 702 is close to the position of the back shell cover that needs to be glued. Then the glue applicator 702 is controlled to start discharging glue, and the motor 703 is started to drive the small gear 704 to rotate, and then the large gear 706 is used to drive the glue ring 705 to rotate. The glue connecting rod 708 will slide along the slide between the annular guide frame 709 and the annular guide block 710. This slide has the same shape and size as the position where the earphone shell needs to be glued. The glue applicator 702 is driven by the fixed frame 701 to move one circle to complete the gluing process, and then the glue applicator 702 is controlled to stop discharging glue, and the large electric push rod 202 is controlled to retract and reset.

[0050] like Figure 8 and Figure 13 As shown, it also includes a pressing plate 8 for pressing the rear shell cover onto the earphone shell, and two pressing plates 8 are symmetrically fixed to the translation plate 203.

[0051] The electric turntable 102 rotates counterclockwise and rotates ninety degrees each time. The first station is the gluing station, the second station is the station for placing the back shell cover on the earphone shell, the third station is the station for pressing the back shell cover onto the earphone shell, and the fourth station is the unloading station. The translation plate 203 moves downward to drive the pressing plate 8, which presses the back shell cover onto the earphone shell through the pressing plate 8 so that the two are buckled together.
