Description

Technical Field

[0001] The present invention relates to the technical field of communication equipment production, and in particular to a molding processing device for communication equipment. Background Art

[0002] The RRU, or Remote Radio Unit, is a core component of wireless communication base stations, particularly in 4G / 5G networks. It is responsible for converting, amplifying, and transmitting and receiving baseband and radio frequency signals and is typically installed on a tower or pole near the antenna.

[0003] The RRU generates high heat during operation. To prevent deformation of the internal PCB board under high-temperature conditions, a large number of densely packed screws are usually screwed into the PCB board during the assembly and production process of the RRU to ensure that balanced and stable pressure is provided to various areas of the PCB board. However, as a large number of densely packed screws are tightened one by one, a certain compressive stress is applied to the tightened plate area. As the screws in other areas are gradually tightened, tension or compression may occur in local areas of the plate, reducing the overall strength of the PCB plate. In addition, to reduce radio frequency signal loss, gold-plated PCB plates are usually used in the RRU. However, current automated mechanical assembly can easily scratch or contaminate the soft and thin gold-plated layer of the plate during the entire production and assembly process, which can lead to poor welding or high-frequency impedance mutations. Therefore, a forming and processing device for communication equipment is proposed. Summary of the Invention

[0013] Compared with the prior art, the application has the following beneficial effects: 1. Through the arrangement of the negative pressure assembly, a temporary micro-negative pressure low-pressure heat insulation environment can be formed on the top of the limiting insert plate by pressing the sealing rubber pad through the heat dissipation fins before assembly, and when the heat dissipation fins in this environment are simulated and heated, the local temperature change on the heat dissipation fins will be more obvious and easier to be captured by the temperature measuring sensor due to the thin air and slow heat transfer, thereby realizing the preposition of quality detection and greatly reducing the cost and risk of subsequent rework.

[0014] 2. This solution uses the recessed airbag to protect the fragile gold-plated circuit board surface during the screw's falling process, preventing scratches and ensuring high-frequency signal integrity.

This redistributes the concentrated stress generated by screw tightening and the stress in the surrounding area, making them uniform. This effectively prevents micro-deformation, cracking, or long-term reliability degradation of the circuit board caused by stress concentration. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the above benefits: this can quickly complete the parts preparation and feeding before the assembly of the heat dissipation aluminum shell 3 and the gold-plated circuit board 4; The side wall of the spin lock mechanism 14 is connected with a plurality of steering seats 18 arranged in a ring array, the steering seat 18 is connected with a negative pressure seat 21 through a hydraulic push rod 19, the inner side wall of the negative pressure seat 21 is connected with a recessed air bag 22, and the bottom of the negative pressure seat 21 is connected with a tensioning assembly for limiting the tightening area of the locking screw 12.

[0023] It should be noted that: when the heat dissipation aluminum shell 3 and the gold-plated circuit board 4 are assembled, the multi-degree-of-freedom mechanical arm 2 moves the rotating lock mechanism 14 and the star-shaped plug plate 16 above the lock screw 12 to be picked up, then controls the shaft center of the star-shaped plug plate 16 bottom to be connected with the star-shaped groove shaft center of the lock screw 12, then uses the rotating lock mechanism 14 to control the shaft center of the star-shaped plug plate 16 to rotate on the shaft center of the lock screw 12 star-shaped groove, because the magnetic attraction seat 15 will generate magnetic attraction force on the lock screw 12, if the star-shaped plug plate 16 and the star-shaped groove on the lock screw 12 reach the adaptive angle, the lock screw 12 will be attracted by the magnetic attraction seat 15, realize the adaptive connection of the star-shaped plug plate 16 and the lock screw 12, then move the lock screw 12 to the upper of the gold-plated circuit board 4 to be locked area, before the lock screw 12 is rotated down, control the steering seat 18 to drive the hydraulic push rod 19 to deflect downward, then the negative pressure seat 21 and the concave air bag 22 in multiple directions will gather together, at this time, the concave air bag 22 is in the expanded state, and the concave part is also outwardly protruding due to expansion, so that the lock screw 12 is received and wrapped by the multiple gathered concave air bags 22, avoiding the hard lock screw 12 from scratching and damaging the surface gold-plated layer of the gold-plated circuit board 4 before tightening, when the lock screw 12 is moved down to the lock hole on the plate, the hydraulic push rod 19 is used to move the negative pressure seat 21 and the concave air bag 22 down and press on the gold-plated circuit board 4, then in the process of moving down, the suction piston mechanism 20 will suck the gas in the negative pressure seat 21 and the concave air bag 22, so that the internal pressure of the concave air bag 22 is reduced, and then the concave part of the concave air bag 22 is restored, so that the lock screw 12 received and wrapped is exposed, in order to facilitate the subsequent rotating lock mechanism 14 to drive the lock screw 12 to tighten; When the negative pressure seat 21 is pressed on the surface of the gold-plated circuit board 4, the inner arc limiting seat 23 and the outer arc limiting seat 24 are pressed on the surface of the gold-plated circuit board 4, the V-shaped rotating arm 25 in the inner arc limiting seat 23 is deflected under pressure, which will exert an outward pressure stress on the plate locking area, and the V-shaped rotating arm 25 in the outer arc limiting seat 24 is deflected under pressure, which will exert an inward pressure stress on the plate locking area, thereby forming a ring-shaped high-pressure stress area around the locking area, then a pressure stress area is also formed after the lock screw 12 is tightened, after the multi-degree-of-freedom mechanical arm 2 is moved up, the pressure stress areas are blocked and removed, after the separation is removed, the original high-pressure stress area will release energy to the low-pressure stress area, and the stress is redistributed through the elastic deformation of the material inside, resulting in a decrease in the overall pressure stress level and a tendency to be uniform, and the cancellation of the constraint will activate the relaxation mechanism of the residual stress (similar to the stress release process when the material layer is removed in the layer cutting method test), the pressure stress may be partially converted into elastic strain or heat energy, reducing the local stress peak value; Based on the above benefits: this can make the pressure stress area of each area of the gold-plated circuit board 4 uniform, avoid local stress from causing damage to the plate after tightening, and make the assembly and processing of the heat dissipation aluminum shell 3 and the gold-plated circuit board 4 more safe and reliable; In use, the limiting plugboard 5 is pulled apart on the processing table 1 by the spring rod 6, then the heat dissipation fins on the heat dissipation aluminum shell 3 are aligned in the gap between the two adjacent limiting plugboards 5, after the heat dissipation aluminum shell 3 is inserted, the spring rod 6 is used to drive the two limiting plugboards 5 to reset, and the limiting baffle 7 at the end of the limiting plugboard 5 is pressed tightly on the side wall of the heat dissipation aluminum shell 3, realizing the quick limiting and positioning of the heat dissipation aluminum shell 3 in all directions, when the heat dissipation fins on the heat dissipation aluminum shell 3 are pushed to move downward between the adjacent limiting plugboards 5, the heat dissipation fins on the heat dissipation aluminum shell 3 will extrude the sealing rubber pad 8 and drive it to move downward, then the sealing rubber pad 8 will extrude the reset telescopic rod 9 during the downward movement, after the heat dissipation fins on the heat dissipation aluminum shell 3 are pressed tightly with the sealing rubber pad 8, the limiting of the heat dissipation aluminum shell 3 on the limiting plugboard 5 will be more reliable, then with the downward movement of the sealing rubber pad 8, the top of the receiving slot in the limiting plugboard 5 will be in a relative negative pressure state, which applies a temperature simulation to the inside of the heat dissipation aluminum shell 3 (the simulation of temperature control applied to the inside of the heat dissipation aluminum shell 3 is a prior art means, which will not be described in detail here), when detecting the heat dissipation performance of the heat dissipation aluminum shell 3, the temperature sensor in the receiving slot and the heat dissipation fins on the heat dissipation aluminum shell 3 are in a relative vacuum low-pressure environment, so the air density is low and the heat transfer speed is slow, at this time, if the temperature of the heat dissipation fins increases due to the heating of the inside of the heat dissipation aluminum shell 3, the efficiency of heat diffusion of the heat dissipation fins to the surrounding environment will decrease, making the local temperature fluctuation of the heat dissipation fins in this area more obvious, which can make the temperature measurement data more accurate and facilitate the detection of the heat conduction capacity of each heat dissipation fin, i.e. the heat dissipation performance, so that the limiting plugboard 5 can be limited during assembly and processing, and can assist in the detection of the heat dissipation performance before assembly and processing; Before assembling and processing the heat dissipation aluminum shell 3 and the gold-plated circuit board 4, the locking screw 12 is gradually placed into the shaft center of the centrifugal seat 11, the driving motor 10 is operated to drive the centrifugal seat 11 to rotate through the driving shaft, then under the action of the centrifugal force, the locking screw 12 will first enter the conveying groove of the centrifugal seat 11, and then enter the magnetic limiting conveying belt 13, which will convey the locking screw 12 one by one, the conveying of the locking screw 12 by the magnetic limiting conveying belt 13 is a common conveying form for parts processing, which will not be described in detail, so that the parts preparation and feeding before the assembly of the heat dissipation aluminum shell 3 and the gold-plated circuit board 4 can be quickly completed; When the heat dissipation aluminum shell 3 and the gold-plated circuit board 4 are assembled, the multi-degree-of-freedom mechanical arm 2 moves the rotating lock mechanism 14 and the star-shaped plug plate 16 above the lock screw 12 to be picked up, then controls the shaft center of the star-shaped plug plate 16 bottom to butt joint the star-shaped groove shaft center of the lock screw 12, and then uses the rotating lock mechanism 14 to control the shaft center of the star-shaped plug plate 16 to rotate on the shaft center of the lock screw 12 star-shaped groove, because the magnetic attraction seat 15 will generate magnetic attraction force on the lock screw 12, if the star-shaped plug plate 16 and the star-shaped groove on the lock screw 12 reach the adaptive angle, the lock screw 12 will be attracted by the magnetic attraction seat 15, realizing the adaptive butt joint of the star-shaped plug plate 16 and the lock screw 12, then the lock screw 12 is moved above the area to be locked of the gold-plated circuit board 4, before the lock screw 12 is rotated down, the control turning seat 18 drives the hydraulic push rod 19 to deflect downward, then the negative pressure seat 21 and the concave air bag 22 in multiple directions will gather together, at this time the concave air bag 22 is in the expanded state, and the concave part also protrudes outward due to expansion, so that the lock screw 12 is received and wrapped by the multiple gathered concave air bags 22, avoiding the hard lock screw 12 from scratching and damaging the surface gold-plated layer of the gold-plated circuit board 4 before tightening, when the lock screw 12 is moved down to the locking hole on the board, the hydraulic push rod 19 is used to move the negative pressure seat 21 and the concave air bag 22 down and press on the gold-plated circuit board 4, then in the process of moving down, the suction piston mechanism 20 will suck the gas in the negative pressure seat 21 and the concave air bag 22, so that the internal pressure of the concave air bag 22 is reduced, and then the concave part of the concave air bag 22 is restored, so that the lock screw 12 received and wrapped is exposed, in order to facilitate the subsequent rotating lock mechanism 14 to drive the lock screw 12 to tighten; When the negative pressure seat 21 is pressed on the surface of the gold-plated circuit board 4, the inner arc limiting seat 23 and the outer arc limiting seat 24 will be pressed on the surface of the gold-plated circuit board 4 together, then the V-shaped rotating arm 25 in the inner arc limiting seat 23 is deflected under pressure, which will exert an outward pressure stress on the board locking area, and the V-shaped rotating arm 25 in the outer arc limiting seat 24 is deflected under pressure, which will exert an inward pressure stress on the board locking area, then a ring-shaped high pressure stress area is formed on the periphery of the locking area, then a pressure stress area is also formed after the lock screw 12 is tightened, after the multi-degree-of-freedom mechanical arm 2 is moved up, the barrier of each pressure stress area is cancelled, after the separation is removed, the original high pressure stress area will release energy to the low pressure stress area, through the elastic deformation of the material inside to realize stress redistribution, resulting in the overall pressure stress level being reduced and tending to be uniform, at the same time, the cancellation of the constraint will activate the relaxation mechanism of the residual stress (similar to the stress release process when the material layer is removed in the layer cutting method test), the pressure stress may be partially converted into elastic strain or heat energy, reducing the local stress peak, so that the pressure stress area of each area of the gold-plated circuit board 4 is uniform, avoiding the local stress from causing damage to the board after tightening, making the assembly and processing of the heat dissipation aluminum shell 3 and the gold-plated circuit board 4 more safe and reliable.
