[0035] When the product parent end 14 needs to be clamped, the driving cylinder 3 is started, the output end of the driving cylinder 3 pushes the driving plate 22 fixedly connected with the driving cylinder 3, so that the driving plate 22 slides along the upper surface of the sliding seat 2 to the side away from the driving cylinder 3, and with the movement of the driving plate 22, the two groups of inclined first auxiliary grooves 6 formed in the lower surface of the driving plate 22 slide relative to the first auxiliary wheels 4 on the upper surface of the adjusting seat 15, and since the first auxiliary grooves 6 are in an inclined structure, the inner side wall thereof applies a lateral inward thrust to the first auxiliary wheels 4, under the action of the thrust, the two groups of adjusting seats 15 slide in the sliding channel in the sliding seat 2 in opposite directions against the friction that may exist, and since the outer end of the adjusting seat 15 is fixedly connected with the clamping plate 16, the two groups of clamping plates 16 also move in opposite directions synchronously, gradually approach and finally contact the two side outer walls of the product parent end 14, and the clamping action starts, and in the initial stage of the contact between the clamping plate 16 and the product parent end 14, the buffer plate 17 slidably connected with the clamping plate 16 first contacts the product parent end 14, at this time, the product parent end 14 applies a reaction force to the buffer plate 17, the force is transmitted to the buffer spring 18 through the sliding rod 21, so that the buffer spring 18 is compressed between the buffer plate 17 and the clamping plate 16, the elastic deformation of the buffer spring 18 can effectively absorb the impact force in the initial stage of clamping, so as to avoid the rigid collision between the clamping plate 16 and the product parent end 14, thereby realizing the flexible clamping of the product parent end 14 and protecting the outer surface of the product parent end 14 from being damaged, and in the process that the buffer plate 17 moves to the clamping plate 16, the butt joint rod 19 fixedly connected with the middle part of the clamping plate 16 penetrates through the through hole preformed in the buffer plate 17 and is accurately inserted into the butt joint hole 20 preprocessed in the middle part of the product parent end 14, and the cooperation between the butt joint rod 19 and the butt joint hole 20 not only further ensures the circumferential positioning of the product parent end 14 in the clamped state, effectively prevents the product parent end 14 from rotating or deviating in the subsequent transfer process, but also can assist in judging the accuracy of the clamping position through whether the butt joint is smooth, and if the butt joint rod 19 cannot be smoothly inserted into the butt joint hole 20, it indicates that the clamping position may deviate, so that timely adjustment can be made.

[0036] Embodiment two: as shown in the technical scheme in the Figure 1 、 Figure 6 and Figure 7 , the present application provides the following technical scheme: a double-stroke product assembly mechanism, which discloses that the upper surface of the fixed frame 1 is provided with a second auxiliary groove 7, the upper surface of the sliding seat 2 is fixedly connected with a second auxiliary wheel 5, the second auxiliary wheel 5 is slidably arranged in the second auxiliary groove 7, and the height of the second auxiliary wheel 5 is greater than the height of the first auxiliary wheel 4, and when the first auxiliary wheel 4 is in contact with the first auxiliary groove 6 and the driving plate 22 continues to move, the sliding seat 2 drives the second auxiliary wheel 5 to slide along the second auxiliary groove 7.

[0037] With the continuous movement of the driving plate 22 away from the driving cylinder 3 under the action of the driving cylinder 3, when the first auxiliary wheel 4 slides to the end of the inclined section of the first auxiliary groove 6 and cannot slide inwards any more, that is, the first auxiliary wheel 4 abuts against the first auxiliary groove 6, at this time, the two sets of clamping plates 16 have completely clamped and fixed the product female end 14 through the buffer plate 17, at this time, the driving cylinder 3 continues to output power to drive the movement of the driving plate 22, since the driving plate 22 is in sliding connection with the sliding seat 2, and at this time, the first auxiliary wheel 4 cannot drive the adjustment seat 15 to move through the first auxiliary groove 6, the driving plate 22 will drive the entire sliding seat 2 to start moving through the abutting force of the first auxiliary wheel 4 on the first auxiliary groove 6, in this process, the second auxiliary wheel 5 fixedly connected to the upper surface of the sliding seat 2 is embedded into the second auxiliary groove 7 opened on the upper surface of the fixed frame 1, and slides in the extension direction of the second auxiliary groove 7, since the height of the second auxiliary wheel 5 is greater than that of the first auxiliary wheel 4, the second auxiliary groove 7 can provide higher stability for the movement of the sliding seat 2, effectively preventing the sliding seat 2 from bouncing up and down or shaking left and right during the movement, and ensuring that the sliding seat 2 can drive the stably clamped product female end 14 to move along a fixed trajectory for accurate linear transfer, thereby smoothly completing the second stroke movement from the initial clamping position to the subsequent assembly station, and preparing for the subsequent product assembly operation.

[0038] As shown in the technical scheme in the embodiments three, Figure 2 , Figure 3 , Figure 7 and Figure 9 , the present application provides the following technical scheme: a double-stroke product assembly mechanism is disclosed, the lower surface of the fixed frame 1 is slidably provided with a traction rope 11, and the two ends of the traction rope 11 are provided with a cleaning mechanism between the fixed frame 1, the cleaning mechanism realizes the dust removal treatment of the product female end 14 through the position movement of the sliding seat 2, the cleaning mechanism comprises a folding soft cavity 12, the folding soft cavity 12 is fixedly connected to the lower surface of the fixed frame 1, and the folding soft cavity 12 is fixedly connected with an extrusion plate 23 on the side close to the clamping plate 16, and the extrusion plate 23 is fixedly connected with one end of the traction rope 11, and the other end of the traction rope 11 is fixedly connected to the side of the sliding seat 2, when the sliding seat 2 moves away from the driving cylinder 3, the traction rope 11 exerts traction on the extrusion plate 23 to extrude the folding soft cavity 12, the lower surface of the fixed frame 1 is fixedly connected with a fixed tube 9, the fixed tube 9 penetrates a gas injection pipe 10, and the gas injection pipe 10 is provided with a gas outlet end towards the side of the clamping plate 16, a connecting hose 13 is provided through the side of the gas injection pipe 10 and the side of the folding soft cavity 12, and the side of the extrusion plate 23 and the lower surface of the fixed frame 1 are fixedly connected with a buffer spring 18.

[0039] In the process of moving the product female end 14 to the assembly station by the sliding seat 2, the traction rope 11 fixedly connected to the side of the sliding seat 2 is pulled synchronously. Since the other end of the traction rope 11 is fixedly connected to the extrusion plate 23, and the extrusion plate 23 is slidably arranged on the lower surface of the fixed frame 1, at this time, the traction rope 11 will exert an attractive force on the extrusion plate 23. Under the action of the traction force, the extrusion plate 23 will overcome the elastic tension of the buffer spring 18 connected between the extrusion plate 23 and the lower surface of the fixed frame 1, and move towards the folding soft cavity 12. A certain amount of cleaning gas is stored in the folding soft cavity 12 in advance. When the extrusion plate 23 moves towards the folding soft cavity 12 and contacts the folding soft cavity 12, an extrusion effect is generated on the folding soft cavity 12, so that the cavity volume is reduced and the internal gas pressure is increased. Under the action of the pressure difference, the cleaning gas in the folding soft cavity 12 is pressed into the fixed pipe 9 through the connecting hose 13 connected thereto. The fixed pipe 9 is fixedly installed on the lower surface of the fixed frame 1, one end of the fixed pipe 9 is connected to the connecting hose 13, and the other end of the fixed pipe 9 is connected to the air jet pipe 10. The air outlet port of the air jet pipe 10 is accurately arranged towards the side of the clamping plate 16, that is, directly opposite to the surface of the clamped product female end 14. Therefore, when the cleaning gas is sprayed from the air jet pipe 10, a gas flow with a certain pressure is formed, which can effectively blow away the dust, fine particles, oil stains and other impurities that may be attached to the surface of the product female end 14 during storage or previous processes, so as to prevent these impurities from entering the product or adhering to the connecting surface in the subsequent assembly process, thereby effectively ensuring the connection quality of the product female end 14 and other components, and reducing the probability of occurrence of problems such as poor connection, contact failure or performance degradation of the product caused by impurities.

[0040] When the assembly is completed and the sliding seat 2 is reset under the reverse driving of the driving cylinder 3, the traction force of the traction rope 11 on the extrusion plate 23 disappears. At this time, the stretched buffer spring 18 restores its elastic deformation, pulls the extrusion plate 23 to move away from the folding soft cavity 12, releases the extrusion on the folding soft cavity 12, and the folding soft cavity 12 restores to the original state by relying on its own elasticity, and reabsorbs the cleaning gas from the outside or the preset gas source through the connecting hose 13, so as to prepare for the next cleaning operation.

[0041] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, as long as the modifications, equivalent replacements or improvements are within the spirit and principles of the present application.
