Description

Technical Field

[0001] The present invention relates to the field of power supply equipment production, and particularly to an automatic power socket assembly machine. Background Art

[0002] The power socket mainly includes a housing, plug blades, a card, and an O-ring. The housing is in the shape of a cylinder with one end open and the other end closed. An inner side of the circumferential wall of the open end of the housing is recessed to form a card slot, and the card is arranged in the card slot. A socket is provided on the circular surface of the closed end of the housing, and the plug blade is inserted through the socket. An annular groove is formed around the plug blade on the circular surface of the housing, and the O-ring is arranged in the annular groove.

[0003] The assembly method of the power socket is as follows: manually insert the plug blade into the housing and press it in place with a manual press, manually press the card into the housing with a manual press, and manually install the O-ring into the housing. The defect of such an assembly method is that the assembly efficiency is low, the single-person assembly production capacity is 220 PCS / H, and the assembled quality is unstable, and the unity of the finished product assembly quality cannot be guaranteed.

[0004] In view of the many drawbacks of the manual assembly method, it has become an inevitable choice for enterprises to improve production efficiency and product quality to improve the manual assembly method to an automatic assembly method. However, in the process of automatic assembly, some key technical problems need to be solved, and the most prominent one is how to accurately install the O-ring.

[0005] The O-ring is small in volume and soft in texture. In the process of automatic operation, it is not easy to achieve accurate positioning and installation. On the one hand, a special automatic device needs to be designed to grasp and place the O-ring to ensure that it can accurately fall into the annular groove on the circular surface of the housing. On the other hand, since the O-ring surrounds the plug blade, the automatic device must avoid collision or interference with the plug blade during operation. If the O-ring interferes with the plug blade during installation, it will not only cause the O-ring to be not installed in place, but also may damage the plug blade, thereby affecting the performance of the entire power socket. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an automatic power socket assembly machine that can accurately install the O-ring according to the above technical status.

[0007] The technical solution adopted by the present invention to solve the above technical problem is: an automatic power socket assembly machine, characterized by including a housing carrier for carrying the housing of the power socket; a feeding platform, on the upper surface of which a first groove is opened, and the O-ring is placed in the first groove. The feeding platform is connected to an O-ring feeding device and continuously replenishes the O-ring from the O-ring feeding device; The transfer platform has a second groove on its upper surface, and the second groove is used to place the O-ring transferred from the loading platform; A first transport rod, having a horizontal movement and a vertical lifting mechanism, configured to transport the O-ring from the loading platform to the transfer platform; The second transport rod has a horizontal movement and a vertical lifting mechanism and is configured to transport the O-ring from the transfer platform to the annular groove in the shell.

[0008] Compared with the prior art, the present invention adopts the first transport rod and the second transport rod to transport the O-ring. The O-ring can be tightly clamped on the first transport rod and the second transport rod to be transported to the specified position, which can transport the O-ring more accurately than conventional grasping equipment such as mechanical claws. At the same time, the present invention sets a transfer platform between the loading platform and the shell carrier. Since the O-ring loading device is not stable when transporting the O-ring to the loading platform, if it is directly transported from the loading platform to the shell carrier, inaccurate positioning will result. The first transport rod transports the O-ring from the loading platform to the transfer platform, and then the second transport rod transports it from the transfer platform to the shell carrier, which makes the loading of the O-ring more reliable.

[0009] In order to facilitate the first transport rod to transport the O-ring, preferably, a first rod hole is opened on the bottom surface of the first groove, and the first rod hole has a first state with a smaller hole diameter and a second state with a larger hole diameter; When the first transport rod is separated from the first rod penetration hole, the first rod penetration hole is in a first state, and an O-ring is placed around the outside of the first rod penetration hole; When the first transport rod is inserted into the first rod penetration hole, the first rod penetration hole is in the second state, and the O-ring is tightly clamped on the rod body of the first transport rod.

[0010] The first through-rod hole realizes the specific structure of the mutual transformation between the first state and the second state. Preferably, the loading platform includes two first slide plates that can slide horizontally, the first groove is divided into two parts and respectively distributed on the two first slide plates, the first slide plate is connected to the first elastic reset member, and under the action of the first elastic reset member, the two first slide plates always have a tendency to move in a direction close to each other, and the rod diameter of the first transport rod is larger than the diameter of the first through-rod hole when it is in the first state; When the first transport rod is separated from the first perforated rod, the two first slide plates are pressed against each other under the action of the first elastic reset member, so that the first perforated rod hole is transformed into the first state; When the first transport rod is inserted into the first rod penetration hole, the first transport rod overcomes the elastic force of the first elastic reset member and pushes the first slide plate to both sides, and the two first slide plates move away from each other, so that the first rod penetration hole is transformed into the second state.

[0011] In order to facilitate the second transport rod to transport the O-ring, preferably, a second rod hole is opened on the bottom surface of the second groove, and the second rod hole has a first state with a smaller hole diameter and a second state with a larger hole diameter; When the second transport rod is separated from the second rod penetration hole, the second rod penetration hole is in the first state, and the O-ring is placed around the outside of the second rod penetration hole; When the second transport rod is inserted into the second rod penetration hole, the second rod penetration hole is in the second state, and the O-ring is tightly clamped on the rod body of the second transport rod.

[0012] The specific structure of the second rod-penetrating hole realizing the mutual transformation between the first state and the second state is preferably that the transfer platform includes a plurality of second slide plates which are distributed in a petal shape and can slide horizontally, the second groove is divided into a plurality of parts which are respectively distributed on each second slide plate, the second slide plate is connected to the second elastic reset member, under the action of the second elastic reset member, each second slide plate always has a tendency to move in a direction close to each other, and the rod diameter of the second transport rod is larger than the diameter of the second rod-penetrating hole when it is in the first state; When the second transport rod is separated from the second perforated rod, each second slide plate is pressed against each other under the action of the second elastic reset member, so that the second perforated rod hole is transformed into the first state; When the second transport rod is inserted into the second rod penetration hole, the second transport rod overcomes the elastic force of the second elastic reset member and pushes the second slide plate to both sides, and the two second slide plates move away from each other, so that the second rod penetration hole is transformed into the second state.

[0013] Preferably, the diameter of the first transport rod matches the diameter of the second rod hole in the first state. The first transport rod can be inserted into the second rod hole just enough so that the O-ring transported by the first transport rod can be transported into the second groove and placed with the second rod hole as the center.

[0014] In order to facilitate the separation of the O-ring from the first transport rod after transporting to the designated location, preferably, the first transport rod is covered with a first sleeve, and the first transport rod can move upward relative to the first sleeve until the O-ring tightly clamped on the first transport rod is pushed away by the first sleeve.

[0015] In order to accurately fit the O-ring into the annular groove and to facilitate the detachment of the O-ring from the first transport rod after being transported to a designated location, preferably, the rod head of the second transport rod is complementary to the interior of the housing, and the outer diameter of the rod head of the second transport rod matches the inner diameter of the annular groove of the housing; The second transport rod is covered with a second sleeve on its exterior. The second sleeve can move downward relative to the second transport rod until the O-ring tightly clamped on the second transport rod is pushed away by the second sleeve.

[0016] Specifically, the automatic power socket assembly machine further includes a turntable. The housing carrier is arranged on the turntable and rotates with the turntable.

Among them, the O-ring assembly device includes the feeding platform, the transfer platform, the first transport rod, and the second transport rod. Compared with the manual assembly process, the present invention adjusts the assembly step of the plug and the housing to after the O-ring assembly step, thereby avoiding interference between the second transport rod and the plug during the O-ring assembly process.

[0017] To accurately install structures such as plugs and cards into the housing, it is necessary to sort the directions of the housings so that each housing is rotated to the same specified angle. Preferably, the housing feeding device includes a direction sorting structure. The direction sorting structure includes a sorting platform and a rotating rod. The housing is placed on the sorting platform with the opening facing upward. A convex portion matching the card slot of the housing is provided at the rod head of the rotating rod.

Specific embodiments

[0019] The present invention will be further described in detail below with reference to the embodiments in conjunction with the drawings.

[0020] As Figures 1 to 13 shown, it is a preferred embodiment of an automatic assembling machine for a power socket of the present invention.

[0021] The power socket involved in the present invention is as Figures 11 to 13 shown, and mainly includes a housing 11, three plug blades 12, a card 13 and an O-ring 14. The housing 11 is in the shape of a cylinder with one end open and one end closed. An inner side of the peripheral wall of the open end of the housing 11 is recessed to form a card slot 111. The card 13 is arranged in the card slot 111. A socket 112 is formed on the circular surface of the closed end of the housing 11. The plug blade 12 is inserted through the socket 112. An annular groove 113 is formed around the plug blade 12 on the circular surface of the housing 11. The O-ring 14 is arranged in the annular groove 113.

[0022] Referring to Figure 1 , the automatic assembling machine for the power socket of this embodiment includes a turntable 21. A housing carrier 22 for carrying the housing 11 of the power socket is arranged on the turntable 21, and the housing carrier 22 rotates with the turntable 21. Outside the turntable 21, a housing feeding device 23, an O-ring assembling device 24, a card feeding device 25, a turning device 26, and a plug blade feeding device 27 are sequentially arranged around according to the assembling process of the power socket.

[0023] Among them, the O-ring assembling device 24 includes a feeding platform 241, a transfer platform 242, a first transport rod 243 and a second transport rod 244. As Figure 2As shown in the figure. A first groove 2411 is formed on the upper surface of the loading platform 241. An O-ring 14 is placed in the first groove 2411. The loading platform 241 is connected to an O-ring feeding device (not shown in the figure) and continuously replenishes the O-ring 14 from the O-ring feeding device. A second groove 2421 is formed on the upper surface of the transfer platform 242. The second groove 2421 is used to place the O-ring 14 transferred from the loading platform 241. Both the first transport rod 243 and the second transport rod 244 have horizontal movement and vertical lifting mechanisms. In this embodiment, a set of linkage mechanisms is adopted to control the first transport rod 243 and the second transport rod 244, so that the two move horizontally and vertically synchronously. The O-ring 14 can be tightly fastened on the first transport rod 243 and the second transport rod 244 and transported to a specified position. The first transport rod 243 transports the O-ring 14 from the loading platform 241 to the transfer platform 242, and then the second transport rod 244 transports it from the transfer platform 242 to the housing carrier 22 so that the O-ring 14 is inserted into the annular groove 113 of the housing 11.

[0024] To facilitate the first transport rod 243 to transport the O-ring 14, a first rod-passing hole 2412 is formed on the bottom surface of the first groove 2411. The first rod-passing hole 2412 has Figure 3 a first state with a smaller aperture as shown in the figure and Figure 4 a second state with a larger aperture as shown in the figure. The loading platform 241 includes two first sliding plates 2413 that can slide horizontally. The first groove 2411 is divided into two parts and is respectively distributed on the two first sliding plates 2413. The first sliding plates 2413 are connected to a first elastic reset member 2414. Under the action of the first elastic reset member 2414, the two first sliding plates 2413 always tend to move towards each other. The diameter of the rod part of the first transport rod 243 is larger than the diameter of the first rod-passing hole 2412 in the first state. A first sleeve 245 is sleeved outside the first transport rod 243. The first transport rod 243 can move upward relative to the first sleeve 245 until the O-ring 14 tightly fastened on the first transport rod 243 is pushed away by the first sleeve 245.

[0025] When the first transport rod 243 disengages from the first rod-passing hole 2412, the O-ring 14 is placed around the outside of the first rod-passing hole 2412. The two first sliding plates 2413 are pressed against each other under the action of the first elastic reset member 2414, causing the first rod-passing hole 2412 to change to the first state. When the first transport rod 243 is inserted into the first rod-passing hole 2412, the O-ring 14 is tightly fastened on the rod body of the first transport rod 243. The first transport rod 243 overcomes the elastic force of the first elastic reset member 2414 and spreads the two first sliding plates 2413 apart. The two first sliding plates 2413 move away from each other, causing the first rod-passing hole 2412 to change to the second state.

[0026] In order to facilitate the second transport rod 244 to transport the O-ring 14, a second rod-passing hole 2422 is formed in the bottom surface of the second groove 2421. The second rod-passing hole 2422 has a first state with a smaller aperture as shown in Figure 5 and a second state with a larger aperture as shown in Figure 6 . The transfer platform 242 includes six second sliding plates 2423 that are distributed in a petal shape and can slide horizontally. The second groove 2421 is divided into multiple parts and is respectively distributed on each second sliding plate 2423. The second sliding plate 2423 is connected to the second elastic reset member 2424. Under the action of the second elastic reset member 2424, each second sliding plate 2423 always has a tendency to move towards the direction of approaching each other. The rod diameter of the second transport rod 244 is larger than the diameter of the second rod-passing hole 2422 in the first state. The rod head of the second transport rod 244 is as shown in Figure 7 and is complementary to the interior of the housing 11 as shown in Figure 12 . The outer diameter of the rod head of the second transport rod 244 matches the inner diameter of the annular groove 113 of the housing 11. A second sleeve 246 is sleeved outside the second transport rod 244. The second sleeve 246 can move downward relative to the second transport rod 244 until the O-ring 14 tightly sleeved on the second transport rod 244 is pushed away by the second sleeve 246.

[0027] When the second transport rod 244 is separated from the second rod-passing hole 2422, the O-ring 14 is placed around the outside of the second rod-passing hole 2422. Under the action of the second elastic reset member 2424, each second sliding plate 2423 approaches each other, causing the second rod-passing hole 2422 to change to the first state. When the second transport rod 244 is inserted into the second rod-passing hole 2422, the O-ring 14 is tightly sleeved on the rod body of the second transport rod 244. The second transport rod 244 overcomes the elastic force of the second elastic reset member 2424 and pushes the second sliding plates 2423 apart to both sides. The two second sliding plates 2423 move away from each other, causing the second rod-passing hole 2422 to change to the second state.

[0028] The diameter of the first transport rod 243 is adapted to the diameter of the second rod-passing hole 2422 in the first state. The first transport rod 243 can just be inserted into the second rod-passing hole 2422, so that the O-ring 14 it transports can be exactly transported into the second groove 2421 and placed centered on the second rod-passing hole 2422.

[0029] In order to accurately install structures such as the insert piece 12 and the card 13 into the housing 11, this embodiment needs to be able to sort the direction of the housing 11 so that each housing 11 is rotated to the same specified angle. Therefore, the housing loading device 23 of this embodiment is as shown in Figure 1As shown, it includes a direction sorting structure. The direction sorting structure includes a sorting platform 231 and a rotating rod 232. The housing 11 is placed on the sorting platform 231 with the opening facing upward. A convex portion 2321 matching the card slot 111 of the housing 11 is provided at the rod head of the rotating rod 232. The rotating rod 232 rotates until its convex portion 2321 is engaged with the card slot 111 and drives the housing 11 to rotate, thus completing the direction sorting.

[0030] The housing carrier 22 has two loading positions, namely the first loading position 221 and the second loading position 222. As Figure 8 and Figure 9 shown, the housing 11 is placed into the first loading position 221 of the housing carrier 22 of the turntable 21 through the housing loading device 23. After the O-ring 14 and the card 13 are installed, it is flipped by the flipping device 26 and placed into the second loading position 222 of the housing carrier 22.

[0031] In addition to the above components, this embodiment further includes a housing pressing device 281 for pressing the housing 11 into the housing carrier 22, an O-ring detection device 282 for detecting whether the O-ring 14 is installed in the housing 11, a card pressing device 283 for pressing the card 13, a chip pressing device 284 for pressing the chip 12 into the housing 11, a chip detection device 285 for detecting whether the chip 12 is pressed in place, and a discharge channel 286 for discharging the assembled finished products.

[0032] The working process of this embodiment is as follows: The housing 11 is automatically loaded and automatically sorted in direction by the housing loading device 23 and then placed into the first loading position 221 of the housing carrier 22 of the turntable 21; the housing pressing device 281 presses the housing 11 into the housing carrier 22 for calibration and detection of presence or absence; the O-ring loading device automatically loads and automatically installs the O-ring 14 into the housing 11; the card loading device 25 automatically loads and automatically pre-installs the card 13 into the housing 11; the O-ring detection device 282 detects whether the O-ring 14 is installed in the housing 11; the card pressing device 283 detects whether the card 13 is pre-installed in the housing 11 and synchronously presses the card 13 into the housing 11; the flipping device 26 flips the housing 11 after the O-ring 14 is pressed and calibrated; the chip loading device 27 automatically loads and automatically pre-installs the chip 12 into the housing 11; the chip pressing device 284 presses the chip 12 into the housing 11; the chip detection device 285 detects whether the chip 12 is pressed in place; the discharge channel 286 discharges the qualified and unqualified products.
