Description

Technical Field

[0001] This utility model belongs to the technical field of valve assembly equipment, specifically a pin assembly device for valve bodies. Background Technology

[0002] In existing technologies, the assembly process of high-precision valve bodies in cooling systems of electronic devices such as servers involves creating a slot on the side of the valve seat and manually inserting two small pins into the slot to fix the spring. During the assembly process, the pins are too small, and operators need to use precision tools to grasp, align, and insert them. Each action is time-consuming and requires a high degree of hand stability from the operator. During the assembly process, problems such as pins falling off or being misaligned are prone to occur, resulting in low assembly efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a pin assembly device for valve bodies. After the pin is positioned by a positioning seat, it is pushed into the valve seat slot in the valve seat positioning cavity along its radial direction, so that the pin moves in a limited position throughout the entire process. This solves the problem of low assembly efficiency caused by pin falling off or misalignment during the assembly process in the prior art.

[0004] The technical solution of this utility model is as follows: the pin assembly device for valve body includes: a positioning seat, a pin feeding mechanism and a pin pushing mechanism.

[0005] The pin feeding mechanism and the pin pushing mechanism are located on the side of the positioning seat.

[0006] The positioning seat is provided with a valve seat positioning cavity and a pin positioning cavity. The pin positioning cavity is located to the side of the valve seat positioning cavity and is connected to the valve seat positioning cavity.

[0007] The pin feeding mechanism is used to move the pin into the pin positioning cavity along the axial direction of the pin.

[0008] The pin-pushing mechanism is used to move the pin into the valve seat positioning cavity along the radial direction of the pin.

[0009] In a further embodiment, the pin positioning cavity includes: an axial moving hole, a pin positioning hole, and a radial moving hole.

[0010] The axial moving hole is located at the end of the pin positioning hole, the pin positioning hole is located on the side of the valve seat positioning cavity and communicates with the valve seat positioning cavity, and the radial moving hole is located on the side of the pin positioning hole away from the valve seat positioning cavity.

[0011] The axial moving hole extends along the axial direction of the pin.

[0012] The pin positioning hole and the radial moving hole extend along the radial direction of the pin.

[0013] In a further embodiment, the inner diameter of the axially movable hole is clearance-fitted with the outer diameter of the pin.

[0014] In a further embodiment, the vertical spacing of the pin positioning hole is clearance-fitted with the outer diameter of the pin.

[0015] The left and right spacing of the pin positioning hole is matched with the length clearance of the pin, so that the pin positioning hole can limit the pin in the vertical radial direction and the left and right axial direction.

[0016] In a further embodiment, the pin insertion mechanism includes a radial power source and a push block, wherein the push block is mounted on the radial power source and is disposed on the side of the positioning seat at a position that mates with the pin positioning cavity.

[0017] The radial power source is used to insert the push block into the pin positioning cavity, and to move the pin into the valve seat positioning cavity along the radial direction of the pin.

[0018] In a further embodiment, the positioning seat includes two symmetrically arranged pin positioning cavities.

[0019] The radial power source includes a gripper cylinder, and two push blocks are installed on the gripper cylinder. The push blocks are located on both sides of the positioning seat and in cooperation with the pin positioning cavity. The gripper cylinder drives the two push blocks to move simultaneously, ensuring the synchronicity of the pin movement and improving the success rate of pin assembly.

[0020] In a further embodiment, the pin feeding mechanism includes a pin vibratory feeder and a feeding power assembly.

[0021] The feeding power assembly is located at the discharge end of the pin vibratory plate. The pin vibratory plate is used to feed pins to the feeding power assembly, and the feeding power assembly is used to feed the pins to the pin positioning cavity of the positioning seat.

[0022] In a further embodiment, the feeding power assembly includes: a feeding radial power source, a feeding axial power source, and a pin.

[0023] The radial power source for feeding is located at the discharge end of the pin vibrating plate, the radial moving block for feeding is installed on the radial power source for feeding, the axial power source for feeding is located on the side of the discharge end of the pin vibrating plate for feeding, and the pin is installed on the axial power source for feeding.

[0024] The feeding radial moving block is provided with a pin buffer cavity, and the pin vibrating plate is used to transport the pins to the pin buffer cavity.

[0025] The radial power source for feeding is used to make the radial moving block for feeding rotate between the position that cooperates with the pin vibrating plate and the position that cooperates with the insert pin.

[0026] When the feeding radial moving block moves to a position that matches the pin moving path, the feeding axial power source uses the pin to move the pin in the pin buffer cavity to the pin positioning cavity. By pre-positioning and buffering the pin in the pin buffer cavity of the feeding radial moving block, the interference of the pin vibration plate on the pin feeding can be reduced, so that the feeding axial power source and the pin can simultaneously move multiple pins that match the pin positioning cavity to the pin positioning cavity.

[0027] In a further embodiment, the pin assembly device further includes: a first conveying mechanism and a slot position detection device.

[0028] The first conveying mechanism and the slot position detection device are located on the side of the positioning seat. The first conveying mechanism is used to make the valve seat move between the slot position detection device and the positioning seat.

[0029] The slot position detection device is used to identify the direction of the slotted part of the valve seat, so that the first conveying mechanism can match the slotted part of the valve seat with the pin positioning cavity of the positioning seat.

[0030] In a further embodiment, the slot position detection device includes: an optical fiber sensor, a positioning element, and a vision camera.

[0031] The number of fiber optic sensors matches the number of slots in the valve seat, and the vision camera and multiple fiber optic sensors are arranged circumferentially around the positioning element.

[0032] When the first conveying device moves the valve seat onto the positioning component, it causes the valve seat to rotate. The position of the valve seat's slot is detected by a fiber optic sensor. After the fiber optic sensor detects the position of the valve seat's slot, a vision camera is used to take a picture for confirmation, reducing the error rate. Compared with existing technologies that only use a vision camera to detect the slot position, this greatly reduces the complexity of the vision camera detection algorithm.

[0033] The beneficial effects of this utility model are as follows: This application positions the pin by means of a positioning seat, and the valve seat positioning cavity accommodates the part of the valve seat with a slot. The pin feeding mechanism can move the pin into the pin positioning cavity along the axial direction of the pin, and limit the pin by means of the pin positioning cavity. Then, the pin is moved into the valve seat positioning cavity along the radial direction of the pin, so that the pin is pushed into the valve seat slot along its radial direction. The pin is limited by the pin positioning cavity throughout the movement, which solves the problem of low assembly efficiency caused by the pin falling off or misaligning during the assembly process in the prior art.

[0047] The pin-pushing mechanism 2 is used to move the pin into the valve seat positioning cavity along the radial direction of the pin.

[0048] The first conveying mechanism 3 and the slot position detection device 4 are located on the side of the positioning seat 5. The first conveying mechanism 3 is used to make the valve seat move between the slot position detection device 4 and the positioning seat 5.

[0049] The slot position detection device 4 is used to identify the direction of the slotted part of the valve seat, so that the first conveying mechanism 3 can match the slotted part of the valve seat with the pin positioning cavity of the positioning seat 5.

[0051] The slot is a through-slot structure connecting both sides of the valve seat. The number of fiber optic sensors 41 matches the number of slots in the valve seat. The vision camera 43 and multiple fiber optic sensors 41 are arranged in a circular pattern around the positioning element 42.

[0052] When the first conveying device 3 moves the valve seat onto the positioning member 42, the first conveying device 3 drives the valve seat to rotate. The position of the valve seat in the slot is detected by the fiber optic sensor 41, and a vision camera is used to take pictures for confirmation to reduce the error rate. Figure 1 The positioning element 42 shown is a shaft inserted into the valve seat. The positioning element 42 is used to assist in manually adjusting the valve seat to confirm its position.

[0056] like Figure 2 The pin positioning cavity shown includes: an axial movement hole 51, a pin positioning hole 52, and a radial movement hole 53.

[0057] An axial moving hole 51 is provided at the end of a pin positioning hole 52. The pin positioning hole 52 is located on the side of the valve seat positioning cavity and communicates with the valve seat positioning cavity. A radial moving hole 53 is provided on the side of the pin positioning hole 52 away from the valve seat positioning cavity.

[0058] The axial moving hole 51 extends along the axial direction of the pin.

[0059] The pin positioning hole 52 and the radial moving hole 53 are provided to extend along the radial direction of the pin.

[0060] In this embodiment, the inner diameter of the axial moving hole 51 is clearance-fitted with the outer diameter of the pin.

[0061] In this embodiment, the vertical spacing of the pin positioning hole 52 is clearance-fitted with the outer diameter of the pin, and the horizontal spacing of the pin positioning hole 52 is clearance-fitted with the length of the pin. Figure 3 and 4 The pin positioning hole 52 shown is a contour structure that matches the shape of the pin.

[0062] In this embodiment, the pin insertion mechanism 2 includes a radial power source 21 and a push block 22. The push block 22 is installed on the radial power source 21 and is located on the side of the positioning seat 5 at a position that cooperates with the pin positioning cavity. The radial power source 21 can be a linear power mechanism such as a lead screw mechanism, a gear and rack mechanism, or a cylinder.

[0063] The radial power source 21 is used to insert the push block 22 into the pin positioning cavity, and to move the pin along the radial direction of the pin into the valve seat positioning cavity.

[0064] like Figure 4 The positioning seat 5 shown includes two symmetrically arranged pin positioning cavities.

[0065] The radial power source 21 includes a gripper cylinder, and two push blocks 22 are installed on the gripper cylinder. The push blocks 22 are located on both sides of the positioning seat 5 and in cooperation with the pin positioning cavity. In other embodiments, the gripper cylinder can be an electric gripper.

[0066] like Figure 5 The pin feeding mechanism 1 shown includes: a pin vibratory plate 11 and a feeding power assembly.

[0067] The feeding power assembly is located at the discharge end of the pin vibratory plate. The pin vibratory plate is used to feed pins to the feeding power assembly, and the feeding power assembly is used to feed the pins to the pin positioning cavity of the positioning seat 5.

[0068] like Figure 5 The feeding power assembly shown includes: a feeding radial power source 12, a feeding axial power source 13, and a pin 14.

[0069] The radial power source 12 for feeding is located at the discharge end of the pin vibratory plate, the radial moving block 15 for feeding is installed on the radial power source 12 for feeding, the axial power source 13 for feeding is located on the side of the discharge end of the pin vibratory plate for feeding, and the pin 14 is installed on the axial power source 13 for feeding.

[0070] The radial moving block 15 for feeding is equipped with a pin buffer cavity. The pin vibratory feeder is used to transport the pins into the pin buffer cavity, such as... Figure 5 The pin vibratory feeder shown is equipped with a pin conveying track, which has two pin channels, allowing two pins to be inserted into two pin buffer cavities from the pin channels.

[0071] The feeding radial power source 12 is used to make the feeding radial moving block 15 rotate between the position that mates with the pin vibrating plate and the position that mates with the insert pin 14.

[0072] When the feeding radial moving block 15 moves to a position that matches the moving path of the pin 14, the feeding axial power source 13 uses the pin 14 to move the pin in the pin buffer cavity to the pin positioning cavity.

[0073] Instructions for use: The second conveying mechanism 8 moves the gasket and spring into the valve seat positioning cavity of the positioning seat 5 respectively.

[0074] The first transport mechanism 3 moves the valve seat to a position that mates with the slot position detection device 4. Then, the first transport mechanism 3 drives the valve seat to rotate so that the slot position detection device 4 identifies the position where the valve seat has a slot. Then, the first transport mechanism 3 moves the slotted part of the valve seat to a position that mates with the pin positioning cavity of the positioning seat 5.

[0075] The pin 14 of the pin feeding mechanism 1 passes the pin through the axial moving hole 51 of the pin positioning cavity, so that the pin moves into the pin positioning hole 52.

[0076] After the second transport mechanism 8 moves the gasket and spring into the valve seat positioning cavity of the positioning seat 5, the first transport mechanism 3 moves the valve seat into the valve seat positioning cavity of the positioning seat 5. Then, the pin-pushing mechanism 2 inserts the push block 22 into the pin positioning cavity, and the push block 22 moves the pin to the valve seat's slot in the valve seat positioning cavity along the radial direction of the pin. During this process, the first transport mechanism 3 applies a downward force to the valve seat to compress the spring, allowing the pin to move to the valve seat's slot. Then, the first transport mechanism 3 stops applying a downward force to the valve seat to reset the spring, and the spring applies a force to the pin to engage with the valve seat's slot.
