Description

Technical Field

[0001] This invention relates to the field of fan installation equipment technology, specifically to an automatic CPU cooling fan installation device. Background Technology

[0002] When installing a CPU cooling fan, bolts are generally used for installation and fixation. The bolts are used to firmly fix the heatsink base or fan bracket to the motherboard, while the washers (usually made of plastic or rubber) serve to absorb shock, insulate, and protect the motherboard, preventing direct metal contact that could cause short circuits or scratches to the circuitry.

[0003] A screw-driving device for assembling a fan blade motor in fan processing, with application publication number CN121715851A, includes a worktable. A positioning frame is bolted onto the worktable. Several lifting rods are threaded through the center of the upper surface of the positioning frame. A positioning ring is horizontally positioned at the top of each lifting rod. The positioning ring is used to position the fan motor and fan blades. Several screwdrivers are also provided on one side of the positioning frame on the upper surface of the worktable. This invention uses screwdrivers to precisely install bolts, effectively improving processing efficiency and torque consistency.

[0004] However, this fan mounting device has the following drawbacks in practical use: Existing fan mounting equipment requires washers on the outside of the bolts to ensure precision and provide shock absorption, insulation, and motherboard protection when installing fans with bolts. Traditionally, the washers are first assembled onto the motherboard's mounting position, then bolts are screwed in to secure them, reducing bolt gaps and improving overall stability. However, vibrations during equipment operation can cause the washers to loosen or fall off. Furthermore, operating multiple independent assembly units in the same space significantly increases costs and requires ample space, hindering automated production lines. When screwing in and installing bolts, the bolts need to be initially positioned in the motherboard mounting holes. At this stage, issues such as thread scraping, cold welding, or seizing can easily occur due to deviations in the bolt screwing angle or forced screwing. Additionally, in the initial stage of bolt screwing, localized pressure exists at the bolt location, making the bolt susceptible to damage due to localized stress concentration. Summary of the Invention

[0015] As a preferred embodiment of the present invention, the transmission expansion clamping structure includes: A transmission turntable is rotatably connected inside the lower frame. A transmission protrusion is connected to the inner side of the top of the transmission turntable via a displacement cylinder. The transmission protrusion is slidably connected to the top of the transmission turntable and abuts against the side of the transmission ratchet.

The inner side of the pneumatic arc-shaped push rod is fitted with a positioning washer.

[0016] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects: 1. In the automatic CPU cooling fan installation equipment, during the installation of the CPU cooling fan, the gear structure (drive ratchet and drive lug) in a disengaged state first clamps and fixes the washer (without driving the pneumatic arc-shaped push rod), and moves the bolt above the pneumatic arc-shaped push rod. Then, the gear structure (drive ratchet and drive lug) in a meshing state clamps and fixes the washer, and during the clamping and fixing of the washer, the bolt is automatically inserted into the inside of the washer, automatically assembling the washer and bolt. This ensures that the assembly and fixing of the washer and bolt can be completed in one go when installing the cooling fan, improving the efficiency and effectiveness of the cooling fan installation. It should be noted that the washers are pre-fitted onto the bolts, preventing them from slipping off fingertips or falling into the cooling fan during installation, thus avoiding the risk of foreign objects or the need for removal. Furthermore, the vibrating conveyor and washer delivery system can directly supply pre-installed bolts and washers, simplifying automated gripping and installation, making it easier to operate in confined spaces, and resulting in lower equipment costs. 2. In the automatic CPU cooling fan installation equipment, when the bolt is screwed into the corresponding mounting hole inside the cooling fan, the elastic structure design buffers the contact area between the bolt root and the mounting hole, offsetting the stress concentration at the root during the screwing process (in the initial state). This guides the bolt to align with the starting point of the mounting hole thread, preventing thread scraping, cold welding, or seizing caused by forced screwing due to angular deviation. Simultaneously, it continuously provides axial or radial preload to compensate for minor displacements of the threaded pair caused by vibration and impact, effectively preventing the bolt from loosening on its own. Furthermore, after elastic compensation of the bolt's initial position, a positioning cylinder can limit and fix the position of the elastic structure (upper column), ensuring that subsequent bolt installation (screwing) is unaffected by the elastic structure, the screwing depth is error-free, and the washer fits the CPU motherboard more closely. 3. In the automatic CPU cooling fan installation equipment, when installing the assembled bolts and washers into the inside of the CPU cooling fan, the assembled bolts and washers can be rotated 90 degrees to move them horizontally (through a two-way slide rail structure) and install them into the mounting holes inside the cooling fan, thereby achieving automated CPU cooling fan installation and improving the intelligence level of CPU cooling fan installation. 4. In the automatic installation equipment for CPU cooling fans, during the clamping and fixing of bolts, the bolts can be automatically conveyed by a vibrating conveyor plate, and moved to the subsequent clamping and fixing position by an automatic cylinder pusher. This facilitates the subsequent clamping, fixing and installation of the bolts one by one (head up, root down), avoiding problems such as upside down, side leaning, or misalignment of bolts and washers during clamping and installation.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] Please see Figures 1-18An automatic CPU cooling fan installation device includes a machine frame 10; a vibrating conveyor plate 20 installed on one side of the top of the machine frame 10, with a bolt feeding device 30 installed on the top of the machine frame 10 at the discharge port of the vibrating conveyor plate 20; and an automatic bolt and washer assembly and installation device 40 installed on the other side of the top of the machine frame 10. The automatic bolt and washer assembly and installation device 40 assembles bolts and washers, and completes the installation and fixing of the CPU cooling fan by means of the assembled bolts and washers. The automatic bolt and washer assembly and installation device 40 includes a bidirectional slide rail structure 401 installed on the other side of the top of the machine frame 10. A horizontal steering structure 402 is mounted on the side of the bidirectional slide rail structure 401 by screws; a side support body 4020 is mounted on the side of the horizontal steering structure 402 by screws; a vertical buffer positioning structure 403 is mounted on the side of the side support body 4020 by screws; a bolt telescopic clamping assembly 404 is mounted at the bottom of the vertical buffer positioning structure 403; a transmission ratchet 405 is mounted on the outside of the bolt telescopic clamping assembly 404; and a transmission outward expansion clamping structure 406 is in contact with the transmission ratchet 405. A washer is clamped and fixed on the inner side of the transmission outward expansion clamping structure 406, and the transmission outward expansion clamping structure 406 is located on the outside of the bolt telescopic clamping assembly 404.

[0022] It should be noted that a washer conveying system is installed on the side of the equipment frame 10 to convey the washers to the side of the bolt feeding device 30, and the washer is clamped and installed through the transmission expansion clamping structure 406. A control terminal 101 is installed on the side of the equipment frame 10, which controls the feeding, clamping, assembly and installation of the bolts and washers.

[0023] The working principle is as follows: When installing the CPU cooling fan, the washers and bolts are conveyed to their corresponding clamping positions via the conveying device and the bolt feeding device 30 (the bolts are stored inside the vibrating conveyor plate 20), respectively. Then, the bidirectional slide rail structure 401 is activated, moving the bolt telescopic clamping assembly 404 and the transmission expansion clamping structure 406 above the bolts and washers. During the assembly of the washers and bolts, the bolts are first clamped and fixed by rotating the bolt telescopic clamping assembly 404. Then, without activating the transmission expansion clamping structure 406, the washers are pressed and fixed, and the position of the clamped and fixed bolts (vertically) is adjusted. The clamped and fixed bolts (located at the top of the washers) are then inserted into the interior of the washers, completing the assembly of the bolts and washers. After the bolts and washers are assembled, their positions are adjusted using the bidirectional slide rail structure 401. The horizontal steering structure 402 then moves the clamped and positioned bolts and washers from a vertical to a horizontal position, inserting them into the pre-drilled mounting holes on the CPU motherboard. At this point, the bolt telescopic clamping assembly 404 is activated to screw the assembled bolts and washers into the corresponding mounting holes, completing the installation and positioning of the cooling fan.

[0024] For details, please refer to the following: Figure 4 and Figure 5 The bolt feeding device 30 includes an upper support body 301, which is installed on the top of the equipment frame 10 and located on the side of the vibrating conveyor plate 20. A linear conveyor plate 302 is installed on the top of the upper support body 301 and is located on one side of the discharge port of the vibrating conveyor plate 20. Bolts are conveyed inside the linear conveyor plate 302. A lower positioning plate 303 is detachably installed on one side of the top of the linear conveyor plate 302 by screws and presses down and positions the bolts located inside the linear conveyor plate 302. A pushing cylinder 304 is installed on the top of the upper support body 301 and is located on one side of the discharge port of the linear conveyor plate 302. The output end of the pushing cylinder 304 is connected to a pushing component 305. The pushing component 305 positions the bolts through a reserved groove and conveys them to the clamping position of the bolt telescopic clamping assembly 404.

[0025] In this scheme, the pushing component 305 is slidably connected to the top of the pushing guide rail 3051, and the pushing guide rail 3051 is installed on the top of the upper support body 301. An infrared calibration unit 3052 is installed on one side of the top of the pushing component 305, and the infrared calibration unit 3052 detects the position of the bolt.

[0026] In the automatic CPU cooling fan installation device of the present invention, when installing bolts, the bolts located on the vibrating conveyor plate 20 are evenly pushed into the interior of the linear conveyor plate 302 by the operation of the vibrating conveyor plate 20, and the foremost bolt is pushed into the interior of the pusher component 305 by the squeezing between the bolts. Then, the infrared calibration unit 3052 detects the bolt and drives the pusher component 305 to move by activating the pusher cylinder 304, moving the bolt inside the pusher component 305 to the corresponding clamping point.

[0027] For details, please refer to the following: Figure 6 and Figure 7 The bidirectional slide rail structure 401 includes a bottom seat 4011, which is installed on the other side of the top of the equipment frame 10. A first drive source 4012 is installed inside the bottom seat 4011, and the output end of the first drive source 4012 is connected to a first belt 4013 through a synchronous pulley. A horizontal lead screw 4014 is rotatably connected inside the bottom seat 4011 and is connected to the inner side of the first belt 4013 through a synchronous pulley on one outer end. A horizontal slide block 4015 is connected to the outer side of the horizontal lead screw 4014 and is slidably connected inside the bottom seat 4011. The horizontal slide block 4015 is slidably connected to horizontal guide rails 4016 installed on both sides inside the bottom seat 4011.

[0028] In this design, a longitudinal frame 40151 is mounted on the top of the horizontal slide block 4015. A second drive source 40152 is installed inside the longitudinal frame 40151. The output end of the second drive source 40152 is connected to a second lead screw 40153 rotatably connected inside the longitudinal frame 40151. A longitudinal slide block 40154 is connected to the outside of the second lead screw 40153. The longitudinal slide block 40154 is slidably connected inside the longitudinal frame 40151. A horizontal steering structure 402 is mounted on the side of the longitudinal slide block 40154 by screws.

[0029] In the automatic CPU cooling fan installation device of the present invention, during the clamping and installation of bolts and washers, the first drive source 4012 is activated to drive the first belt 4013 connected to the outside via a synchronous pulley, causing the horizontal lead screw 4014 connected to the inside of the first belt 4013 via the synchronous pulley to rotate. When the horizontal lead screw 4014 rotates, the horizontal slide block 4015 connected to its outside moves horizontally inside the bottom seat 4011. The second drive source 40152 is activated to drive the second lead screw 40153 connected to the output end of the second drive source 40152 to rotate, causing the longitudinal slide block 40154 mounted on the outside of the second lead screw 40153 to move telescopically inside the longitudinal frame 40151, thereby realizing the horizontal and vertical adjustment of the bolt and washer positions.

[0030] For details, please refer to the following: Figure 8 , Figure 9 and Figure 10 The horizontal steering structure 402 includes a mounting base 4021, which is screwed onto the side of a longitudinal slide block 40154. A linear cylinder 4022 is mounted at the center of the side of the mounting base 4021. The output end of the linear cylinder 4022 is connected to a metal seat 4023. The metal seat 4023 is slidably connected to the top of a positioning guide rail 4025 via guide blocks 4024 on both sides of its bottom. The positioning guide rail 4025 is mounted on the upper and lower sides of the side of the mounting base 4021. A rotating block 4026 is rotatably connected inside the metal seat 4023. A cam block 4027 is rotatably connected to the bottom of the rotating block 4026. The rotating block 4027 is movably connected to the back of the metal seat 4023. The protruding part on the side of the cam rotating block 4027 extends into the interior of the arc-shaped groove 4028. The arc-shaped groove 4028 is opened inside the mounting seat 4021, and the cam rotating block 4027 can rotate 90 degrees through the arc-shaped groove 4028. The rotating base 4029 is connected to the rotating block 4026. The rotating base 4029 is rotatably connected to the interior of the annular guide rail 40211 on the side of the mounting seat 4021 through the guide wheel 40210 installed at the bottom edge. The side of the rotating base 4029 is fitted with a side bracket 4020 by screws.

[0031] In the automatic CPU cooling fan installation device of the present invention, after the bolts and washers are assembled, the linear cylinder 4022 is activated, driving the metal seat 4023 connected to the output end of the linear cylinder 4022 to extend and retract outside the positioning guide rail 4025. When the metal seat 4023 extends and retracts, the rotating block 4026 rotatably connected inside it will rotate 90 degrees under the action of the bottom cam rotating block 4027 and the arc groove 4028 provided by the Z-shaped structure, so that the rotating base disk 4029 connected to the rotating block 4026 will rotate 90 degrees, from the vertical direction to the horizontal direction.

[0032] It should be noted that the design of the annular guide rail 40211 and the guide wheel 40210 ensures the stability of the rotating base plate 4029 when it rotates 90 degrees.

[0033] For details, please refer to the following: Figure 11 , Figure 12 and Figure 13 The vertical buffer positioning structure 403 includes a side base 4031, which is screwed onto the side of the side support body 4020. A telescopic electric cylinder 4032 is installed on one side of the top of the side base 4031. The output end of the telescopic electric cylinder 4032 is connected to an upper column 4033. The upper column 4033 has two configurations depending on the installation position: one type slides within a straight groove 4034 opened inside the side base 4031, and the other type is fixedly installed inside the side base 4031. An outer vertical sleeve 4035 is slidably connected inside the side base 4031 and fitted onto the outer side of the bottom of the upper column 4033. A first spring 4036 is installed at the inner bottom of the outer vertical sleeve 4035. The bottom of the 35 is fitted with a lower column 4037 by screws. The lower column 4037 slides to the bottom of the side base 4031. A bolt telescopic clamping assembly 404 is installed at the bottom of the lower column 4037. A vertical guide rod 40371 is installed at the top edge of the lower column 4037. The vertical guide rod 40371 passes through the upper column 4033. A second spring 40372 connected to the top of the upper column 4033 is sleeved on the outside of the vertical guide rod 40371. A positioning cylinder 4038 is installed on the side of the outer vertical sleeve 4035. The output end of the positioning cylinder 4038 is connected to a positioning rod 4039. The positioning rod 4039 extends into the interior of the damping groove 40310 on the surface of the upper column 4033 and limits and fixes the position of the upper column 4033.

[0034] In the automatic CPU cooling fan installation device of the present invention, when the bolt and washer are installed, and the tip of the bolt abuts against the inside of the mounting hole, and the bolt is screwed into the mounting hole, the direct collision between the two generates a compressive force to the lower column 4037. This causes the outer vertical sleeve 4035 connected to the top of the lower column 4037 to extend and retract horizontally, compressing the first spring 4036 inside the outer vertical sleeve 4035 and the second spring 40372 on the outer side of the top of the outer vertical sleeve 4035. At this time, the elastic force of the first spring 4036 and the second spring 40372 buffers and dampens the compressive force, continuously providing axial or radial preload, compensating for the small displacement of the threaded pair caused by vibration, impact, or temperature changes, effectively preventing the screw from loosening on its own, and avoiding problems such as scraping, cold welding, or seizing of the bolt surface threads. At the same time, it alleviates the stress concentration at the bolt thread end, preventing damage.

[0035] It should be noted that during the installation of bolts and washers, the positioning cylinder 4038 can be activated to drive the positioning rod 4039 connected to the output end of the positioning cylinder 4038 to extend and retract, and abut against the inside of the damping groove 40310 to limit and fix the position of the upper column 4033, ensuring that there will be no shaking when the bolt is screwed in later.

[0036] For details, please refer to the following: Figure 15 , Figure 16 and Figure 18 The bolt telescopic clamping assembly 404 includes a lower frame body 4041, which is installed at the bottom of a lower column body 4037. A vertical reciprocating screw 4042 is rotatably connected inside the lower frame body 4041. The vertical reciprocating screw 4042 is connected to the output end of a third drive source 4043, which is installed at the inner bottom of the lower column body 4037. A transmission ratchet 405 is installed on the outer side of the vertical reciprocating screw 4042. An outwardly extending transmission clamping structure 406 is installed inside the lower frame body 4041. A vertical slider 4044 is also included. The slider 4044 is connected to the outside of the vertical reciprocating lead screw 4042. The vertical slider 4044 is slidably connected to the inside of the lower frame 4041. A connecting rod 4045 is installed at the eccentric part inside the vertical slider 4044. A rotary drive source 4046 is installed at the bottom of the connecting rod 4045. The rotary drive source 4046 is slidably connected to the bottom of the lower frame 4041. The rotary drive source 4046 is located at the bottom of the vertical reciprocating lead screw 4042. A pneumatic gripper 4047 is connected to the output end of the rotary drive source 4046. A bolt is clamped and fixed on the inner side of the pneumatic gripper 4047.

[0037] In the automatic CPU cooling fan installation device of the present invention, when assembling the bolts and washers, the vertical reciprocating screw 4042 connected to the output end of the third drive source 4043 can be rotated by starting the third drive source 4043 to rotate, so that the vertical slider 4044 connected to the outside of the vertical reciprocating screw 4042 moves up and down, driving the rotation drive source 4046 and the pneumatic gripper 4047 (for clamping and fixing the bolt) connected to the bottom of the vertical slider 4044 through the connecting rod 4045 to move up and down, so that the clamped and fixed bolt is inserted into the inside of the washer.

[0038] When the bolts and washers are screwed into the mounting holes inside the motherboard, the rotation drive 4046 drives the pneumatic gripper 4047 (which holds and fixes the bolts) to rotate. In conjunction with the movement of the motherboard (CPU) and the cooling fan (horizontal direction), the bolts and washers are screwed into the mounting holes, completing the installation and fixing of the motherboard (CPU) and the cooling fan.

[0039] For details, please refer to the following: Figure 16 , Figure 17 and Figure 18 The transmission expansion clamping structure 406 includes a transmission turntable 4061, which is rotatably connected to the interior of the lower frame 4041. A transmission protrusion 4063 is connected to the inner side of the top of the transmission turntable 4061 via a displacement cylinder 4062. The transmission protrusion 4063 is slidably connected to the top of the transmission turntable 4061 and abuts against the side of the transmission ratchet 405. The transmission rotation of the transmission turntable 4061 is achieved through the inclined surface on one side of the top of the transmission protrusion 4063. An arc-shaped recess 4064 is formed at an eccentric position inside the transmission turntable 4061. The internal movable connection of 4064 is a movable head 4065, and the outer side of the top of the movable head 4065 is rotatably connected to a telescopic metal arm 4066; a sliding pressure arm 4067 is slidably connected to the eccentric part inside the lower frame 4041, and the sliding pressure arm 4067 is rotatably connected to the bottom of the telescopic metal arm 4066. The inner bottom of the sliding pressure arm 4067 is fixed to a side pressure arm 4069 by a pin 4068, and the inside of the side pressure arm 4069 is fixed to a pneumatic arc-shaped push rod 40610 by screws. A positioning washer is installed on the inner side of the pneumatic arc-shaped push rod 40610.

[0040] In the automatic CPU cooling fan installation device of the present invention, during the clamping, fixing, and assembly (and bolting) of the washers, the vertical reciprocating screw 4042 connected to the third drive source 4043 is rotated by activating the third drive source 4043, which in turn rotates the transmission ratchet 405 connected to the vertical reciprocating screw 4042. At this time, the transmission protrusion 4063 and the transmission ratchet 405 are engaged by activating the displacement cylinder 4062, and the rotation of the transmission ratchet 405 drives the transmission turntable 4061 to rotate. When the transmission turntable 4061 rotates, it can drive the telescopic metal arm 4066 connected to the movable head 4065 inside the arc-shaped recess 4064 through the arc-shaped recess 4064 to operate. This causes the sliding pressure arm 4067 connected to the bottom of the telescopic metal arm 4066 to move in and out (towards or outwards). This causes the pneumatic arc-shaped push rod 40610 installed at the bottom of the sliding pressure arm 4067 through the side pressure arm 4069 to move, and to compress and fix the washer inside the pneumatic arc-shaped push rod 40610.

[0041] It should be noted that the position of the side pressure arm 4069 is adjusted by the pin 4068, and the position and height of the pneumatic arc-shaped push rod 40610 can be changed as needed.
