Description

A valve core installation device for faucet manufacturing Technical Field

[0001] This invention relates to the field of faucet processing technology, and in particular to a valve core installation device for faucet production. Background Technology

[0002] The faucet valve core is used to regulate the pressure and flow of water. It is one of the key components of a faucet and needs to be installed inside the faucet during the production process.

[0003] Patent publication number CN115647775A discloses a continuous pressing device for assembling a faucet valve core, including a chassis, a column, a first fixed frame, a sliding frame, a locking block, and a pressure rod. A column is installed on the left side of the top wall of the chassis, and a first fixed frame is installed on the upper part of the column. A sliding frame is slidably connected inside the first fixed frame, and a pressure rod is slidably connected to the lower part of the sliding frame. A locking block is engaged between the pressure rod and the sliding frame.

[0004] The aforementioned patent requires manual placement of each valve core onto the faucet before pressing it into the faucet. This manual placement is inefficient, resulting in low assembly efficiency for the valve cores. Furthermore, the patent requires manually pulling open the baffle plate before placing the faucet in place, followed by clamping and positioning the faucet using a second pressure spring. However, this faucet positioning requires manual intervention, further reducing valve core assembly efficiency. To address these issues, we have designed a valve core installation device for faucet production that can automatically place the valve core onto the faucet and automatically position the faucet.

[0014] The present invention has the following advantages:

[0015] 1. After the water tap is released from the rear baffle rack, the electric conveyor belt will transport the water tap forward to the rear of the front baffle rack. The water tap is blocked and limited by the front baffle rack, which can automatically position the water tap and make it easier to accurately install the valve core into the water tap later.

[0016] 2. After the valve core is placed on the faucet by the pressing cylinder, the user controls the suction and exhaust pump to release air, thereby pressing the valve core into the pressing cylinder, thus completing the assembly of the faucet valve core. This eliminates the need for manual placement of the valve core on the faucet, improving the assembly efficiency of the faucet valve core.

[0017] 3. By moving the extrusion block inward to squeeze the valve core, the valve core can be clamped, thereby enhancing the stability of the valve core during the removal process. Furthermore, moving the extrusion block inward to squeeze the valve core can calibrate the valve core, thereby improving the accuracy of valve core installation.

[0018] 4. When the electric conveyor belt transports the faucet to contact the rotating block, the faucet squeezes the rotating block, and the rotating block rotates to fit tightly against the faucet, thereby enabling the faucet to be calibrated and limited, which helps to enhance the accuracy of valve core assembly.

[0019] 5. When the valve core installation device for this faucet is required, the valve core can be transmitted to contact the limit block through the transmission component, thereby automatically delivering the valve core to the bottom of the pressing cylinder, which helps to improve the valve core installation efficiency.

[0020] 6. When the pressing sleeve is fitted onto the valve core or the valve core is misaligned, an alarm light will be emitted to remind people to adjust the position of the valve core in time, which is conducive to the accuracy of valve core assembly. Attached Figure Description

The moving frame 74 has a pressing groove. The pressing cylinder 6 moves in the pressing groove of the moving frame 74. The upper and lower parts of the left and right sides of the first slider 5 are fixedly connected to the first spring 75. The inner and outer ends of the first spring 75 are respectively connected to the first slider 5 and the moving frame 74. The stop block 76 is welded to the upper left side of the fixed frame 3. The stop block 76 is located to the left of the first slider 5.

[0042] As shown in Figures 1, 5, 6, and 7, the blocking mechanism 8 includes a second slider 81, a roller 82, a pull wire 83, a stop rack frame 84, a second spring 85, a rotating shaft 86, and a full gear 87. The second slider 81 is slidably connected to the right rear side of the fixed frame 3, and the second slider 81 is located to the right of the movable frame 74. A stop block 76 is also welded to the upper right side of the fixed frame 3, and the right-side stop block 76 is located to the right of the second slider 81. A pull wire 83 is fixedly connected to the second slider 81. Rollers are rotatably connected to both the upper and lower sides inside the fixed frame 3. 82. The pull wire 83 passes around the roller 82. The rotating shaft 86 is rotatably connected to the upper side of the inside of the base 1. A full gear 87 is sleeved on the rotating shaft 86. The front and rear sides of the upper part of the base 1 are slidably connected to the stop rack frame 84.

The pull wire 83 is connected to the right rear side of the stop rack frame 84 on the rear side. The upper right part of the stop rack frame 84 on the rear side is connected to the second spring 85. The left side of the second spring 85 is connected to the fixed frame 3.

[0043] When assembling the faucet valve core, this faucet production valve core installation device can be used to install the faucet valve core into the faucet. First, the faucet is placed on the upper rear side of the conveyor belt of the electric conveyor 2, and the valve core is placed on the upper right side of the base 1, so that the valve core is directly below the pressing cylinder 6. Then, the electric conveyor 2 is started, and the conveyor belt of the electric conveyor 2 transports the faucet from back to front. Then, the first motor 71 is started. The output shaft of the first motor 71 rotates, causing the lead screw 73 to rotate through the coupling 72, thereby causing the moving frame 74 to move to the right. The movement of the moving frame 74 to the right causes the first slider 5 to move to the right. When the first slider 5 moves to the right and contacts the second slider 81, the first slider 5 pushes the second slider 81 to move to the right. When the second slider 81 moves to the right and abuts against the right-side stop block 76, the second slider 81 stops moving. The moving frame 74 continues to move to the right, the left first spring 75 is compressed, and the right first spring 75 is stretched. The extrusion groove on the moving frame 74 presses the pressing cylinder 6 downward, and the pressing cylinder 6 moves downward and fits onto the valve core. People start the suction and suction dual-purpose air pump 4, which sucks away the air in the pressing cylinder 6 through the air pipe 41. The air pressure in the pressing cylinder 6 is negative, so that the valve core is attracted to the lower side inside the pressing cylinder 6. This completes the automatic removal of the valve core. The second slider 81 moves to the right and pulls the pull line 83 to the right. Under the guidance of the roller 82, the pull line 83 pulls the rear stop rack frame 84 to the left, and the second spring 85 is compressed. The rear stop rack 84 moves to the left, causing the full gear 87 to rotate. This, in turn, causes the front stop rack 84 to move to the right, and the rear stop rack 84 moves to the left, limiting and blocking the faucet. The faucet is in a waiting state, facilitating the subsequent installation of valve cores one by one. Then, the output shaft of the first motor 71 is reversed, which causes the lead screw 73 to reverse through the coupling 72. The reverse rotation of the lead screw 73 causes the moving frame 74 to move to the left, disengaging from the right-side stop block 76. The first spring 75 returns to its original position, causing the first slider 5 to move to the left and return to its original position. The first slider 5 disengages from the second slider 81, and the second slider 81 no longer pulls the pull cable 83. The second spring 85 returns to its original position, causing the rear stop rack 84 to move to the right, which in turn causes the full gear 87 to reverse, thus... The front baffle rack 84 moves to the left, and the rear baffle rack 84 releases the faucet. The faucet is then conveyed forward by the electric conveyor belt to the rear of the front baffle rack 84, where it is blocked and limited. This automatically positions the faucet, facilitating accurate installation of the valve core. The rear baffle rack 84 moves to the right, pulling the pull cable 83, causing the second slider 81 to move to the left and reset. When the first slider 5 moves to the left and resets, it causes the pressing cylinder 6 to move towards the center of the extrusion groove of the moving frame 74, thereby causing the pressing cylinder 6 and the valve core to move upward. Subsequently, the moving frame 74 continues to drive the first slider 5 to move to the left. When the first slider 5 moves to the left and abuts against the left-side stop 76...The first slider 5 stops moving, and the moving frame 74 continues to move to the left. The first spring 75 on the left is stretched, and the first spring 75 on the right is compressed. The pressing groove on the moving frame 74 presses the pressing cylinder 6 downward, placing the valve core above the faucet. The user controls the suction and exhaust pump 4 to release air, thus pressing the valve core into the pressing cylinder 6. This completes the assembly of the faucet valve core, eliminating the need for manual placement and improving assembly efficiency. Afterward, the first motor 71 and lead screw 73 control the moving frame 74 to move to the right. The first spring 75 resets, causing the first slider 5 to move to the right. The first slider 5 causes the pressing cylinder 6 to move towards the center of the pressing groove on the moving frame 74, thus moving the pressing cylinder 6 upward. Subsequently, the moving frame 74 and the first slider 5 move to their rightward reset positions. When faucet valve core assembly is no longer needed, the suction and exhaust pump 4 and the first motor 71 can be turned off.

[0044] Example 2

[0045] Based on Embodiment 1, as shown in Figures 1, 2, 8 and 9, a clamping mechanism 9 is also included. The clamping mechanism 9 includes a pressing block 91, a rotating rod 92, a connecting rod 93 and a sliding sleeve 94. The pressing cylinder 6 is symmetrically and slidably connected to the pressing blocks 91 on the left and right sides of its lower part. The pressing cylinder 6 is mounted on the left and right sides of its lower part via bearings. The rotating rods 92 on the left and right sides are rotatably connected to the pressing blocks 91 on the left and right sides respectively. The sliding sleeve 94 is fixedly connected to the middle of the upper part of the first slider 5. The pressing cylinder 6 slides through the sliding sleeve 94. The sliding sleeve 94 is rotatably connected to the connecting rods 93 on the left and right sides respectively. The rotating rods 92 on the left and right sides are rotatably connected to the connecting rods 93 on the left and right sides respectively.

[0046] During the process of driving the pressing cylinder 6 to move downward to pick up the valve core, as the pressing cylinder 6 moves downward, the rotating rod 92 rotates outward under the traction of the connecting rod 93, thereby causing the squeezing block 91 to move outward. When the pressing cylinder 6 moves downward and fits onto the valve core, the valve core is located between the squeezing blocks 91. The pressing cylinder 6 then moves upward, causing the rotating rod 92 to move inward, thereby causing the squeezing block 91 to move inward and squeeze the valve core, thus clamping the valve core and enhancing the stability of the valve core during the picking process. Moreover, the inward movement of the squeezing block 91 to squeeze the valve core can calibrate the valve core, which helps to improve the accuracy of valve core installation. During the process of driving the pressing cylinder 6 to move downward to put down the valve core, the rotating rod 92 rotates outward, causing the squeezing block 91 to move outward, thereby releasing the valve core and making it easier to install the valve core into the faucet. When the pressing cylinder 6 moves upward again, the rotating rod 92 rotates inward to reset, and the squeezing block 91 moves inward to reset.

[0047] As shown in Figures 1, 2, 10 and 11, the system also includes a calibration mechanism 10. The calibration mechanism 10 includes a bracket 101, a slide rod 102 and a rotating block 103. The bracket 101 is bolted to the bottom of the fixed frame 3. The slide rod 102 is slidably connected inside the bracket 101. The slide rod 102 is connected to the front baffle rack frame 84. The rotating block 103 is mounted on the left side of the slide rod 102 via a bearing. The rotating block 103 is slightly tilted to the right. The water tap moves forward and squeezes the rotating block 103.

[0048] The front baffle rack 84 moves to the left, causing the slide bar 102 to move to the left, which in turn causes the rotating block 103 to move to the left. Then, the conveyor belt of the electric conveyor 2 conveys the faucet to contact the rotating block 103. The faucet squeezes the rotating block 103, and the rotating block 103 rotates to fit tightly against the faucet, thereby calibrating and limiting the faucet, which helps to enhance the accuracy of valve core assembly.

[0049] As shown in Figures 1, 2, 12, and 13, the system also includes a feeding mechanism 11. The feeding mechanism 11 includes a U-shaped frame 111, a limiting block 112, a buckle 113, a second motor 114, a connecting shaft 115, and a conveying assembly 116. A U-shaped frame 111 is welded to the upper right of the base 1. The limiting block 112 is slidably connected to the left side inside the U-shaped frame 111. A buckle 113 is slidably engaged on the front left side of the U-shaped frame 111, and the buckle 113 is engaged between the U-shaped frame 111 and the limiting block 112. The second motor 114 is mounted on the U-shaped frame. On the front right side of 111, the output shaft of the second motor 114 rotatably passes through the rear side of the U-shaped frame 111, and the connecting shaft 115 rotatably connects to the middle of the inside of the U-shaped frame 111. A transmission assembly 116 is wound around the output shaft of the second motor 114 and the connecting shaft 115. The valve core is placed on the transmission assembly 116, and the transmission assembly 116 transmits the valve core to the left. The transmission assembly 116 consists of two pulleys and a flat belt. The two pulleys are respectively welded to the output shaft of the second motor 114 and the connecting shaft 115, and the flat belt is wound around the two pulleys.

[0050] When the valve core installation device for this faucet production is needed, multiple valve cores are placed horizontally side by side on the conveying assembly 116. Then, the second motor 114 is started. The output shaft of the second motor 114 rotates, causing the conveying assembly 116 to drive, thereby conveying the valve cores to contact the limiting block 112. This automatically delivers the valve cores to the bottom of the pressing cylinder 6, which helps to improve the valve core installation efficiency. In addition, before placing the valve core, the buckle 113 is pulled out, and the limiting block 112 is pulled left and right according to the specifications of the valve core, so that when the valve core is placed on the right side of the limiting block 112, the center of the valve core corresponds to the pressing cylinder 6. This can meet the assembly needs of valve cores of different specifications and improve practicality. After the limiting block 112 is moved to the required position, the buckle 113 is locked between the limiting block 112 and the sliding rod 122, thereby fixing the limiting block 112.

[0051] As shown in Figures 1, 2, 14, 15, and 16, the system also includes an alarm mechanism 12. The alarm mechanism 12 includes an alarm light 121, a sliding rod 122, a third spring 123, and a contact switch 124. Multiple sliding rods 122 are circumferentially and evenly connected to the lower part of the pressing cylinder 6. The upper part of each sliding rod 122 is wound with a third spring 123. The upper and lower parts of the third spring 123 are respectively connected to the sliding rod 122 and the pressing cylinder 6. The contact switch 124 is sleeved on the lower part of the pressing cylinder 6 and is located above the sliding rod 122. The alarm light 121 is installed on the upper left part of the fixing frame 3 and is electrically connected to the contact switch 124.

[0052] The pressing cylinder 6 moves up and down, causing the sliding rod 122, the third spring 123, and the contact switch 124 to move up and down. When the pressing cylinder 6 is precisely fitted onto the valve core, the sliding rod 122 does not contact the valve core. When the pressing cylinder 6 is fitted onto the valve core and the position of the valve core deviates, the valve core squeezes one or more sliding rods 122, causing the sliding rod 122 to move upward and collide with the contact switch 124. The third spring 123 is stretched, and the alarm light 121 sounds an alarm, thus reminding people to adjust the position of the valve core in time, which is conducive to the accuracy of valve core assembly.

[0053] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
