Referring to fig. 1, 2 and 3, an automatic loading and unloading apparatus 10 is used for processing and molding a plastic hose product 40, and the plastic hose product 40 can be used as a medical instrument. In the processing process, a straight bar 41 made of plastic material and having a straight line shape is provided, and a spiral rib 42c is provided on the straight bar 41. And then bending the straight strip 41 to form a bent piece 42, wherein the bent piece 42 is approximately U-shaped, the bent piece 42 comprises two straight line segments 42a and a bent segment 42b, the two straight line segments 42a are equal in length and are arranged in parallel relatively, one end of the bent segment 42b is connected with the end of one straight line segment 42a, the other end of the bent segment 42b is connected with the end of the other straight line segment 42a, and spiral convex ribs 42c are simultaneously arranged on the outer peripheral surfaces of the two straight line segments 42 a. The spiral ribs 42c on the two straight segments 42a are aligned such that the installation positions of the spiral ribs 42c on the two straight segments 42a are identical. And then the end of the aligned bending piece 42 is inserted into the mold 30, so as to form a joint 43 on the ends of the two straight segments 42a, that is, one joint 43 is connected to each end of the two straight segments 42a far away from the bending segment 42 b. Finally, a runner aggregate 50 (also known as a sprue) is cut away as shown in fig. 13, and the runner aggregate 50 is connected between the joint 43 and the mold 30, so as to obtain the fully molded plastic hose product 40.

Referring to fig. 4, the automatic loading and unloading apparatus 10 includes a conveying device 100, an aligning device 200, a first transfer device 300, a second transfer device 400, a shearing device 500, and an applying device 600. Referring to fig. 1, 2 and 3, the conveying device 100 is used for conveying the straight member 41 and bending the straight member 41 to form a bending member 42. The aligning device 200 bends and buffers the bent piece 42 so that the installation positions of the spiral ribs 42c on the two straight line segments 42a of the bent piece 42 are identical. The first transfer device 300 is used for transferring the bending member 42 from the conveying device 100 to the alignment device 200. The second transfer device 400 is used to transfer the bending member 42 from the alignment device 200 to the mold 30, so that the mold 30 forms the joint 43 on the bending member 42. The shearing device 500 is used to cut off the runner aggregate 50 connected between the joint 43 and the die 30. The applicator 600 applies a release agent to the mandrel 33 of the mold 30 so that the molded plastic hose product 40 can be smoothly separated from the mandrel 33.

Referring to fig. 4 and 5 together, in some embodiments, the conveyor 100 includes a loading mechanism 110, a transfer mechanism 120, and a bending mechanism 130. The feeding mechanism 110 may be a belt conveying mechanism, the feeding mechanism 110 includes two opposite blocking pieces 111 above the belt, the blocking pieces 111 protrude from the belt by a certain height along a vertical direction, so that a first guide groove 112 and a second guide groove 113 are formed between the blocking pieces 111, and the first guide groove 112 and the second guide groove 113 are used for conveying the straight member 41. The first guide groove 112 is closer to the bending mechanism 130 than the second guide groove 113, the second guide groove 113 has a first end 113a and a second end 113b, the first end 113a is communicated with the first guide groove 112, the width of the second guide groove 113 gradually decreases from the second end 113b to the direction of the first end 113a, and the width of the first guide groove 112 is equal everywhere. In short, the first guide groove 112 is substantially rectangular, and the second guide groove 113 is substantially V-shaped. The first guide groove 112 is close to the output end of the belt, the second guide groove 113 is close to the input end of the belt, and the second guide groove 113 is in a V shape, so that the straight condition 41 from the input end of the belt can be reduced in interference and smoothly enters the second guide groove 113, and the second guide groove 113 plays a good role in guiding the conveying of the straight condition 41. When the straight member 41 enters the first guide groove 112, the first guide groove 112 provides a good limit function for the straight member 41, so that the straight member 41 is output from the belt at a specific position.

The feeding mechanism 110 further encloses an air cylinder at the belt output section and a stop block 114, the stop block 114 is connected with a piston rod of the air cylinder, the air cylinder can push the stop block 114 to move, and the moving direction of the stop block 114 is perpendicular to the conveying direction of the belt. When the piston rod is extended to position the stopper 114 on the conveying trajectory of the straight member 41, the stopper 114 interferes with the conveying of the straight member 41, thereby stopping the straight member 41 from moving directly to the bending mechanism 130.

Referring to fig. 4 and 6, the transferring mechanism 120 is located between the feeding mechanism 110 and the bending mechanism 130, the transferring mechanism 120 includes a fixing frame 121, a slider 122 and a clamping block 123, the slider 122 is connected to the fixing frame 121 in a sliding manner, the sliding direction of the slider 122 is the same as the conveying direction of the belt, for example, the slider 122 slides along the horizontal and longitudinal directions, and the slider 122 can be driven by a rodless cylinder mounted on the fixing frame 121. The clamping block 123 can slide along the vertical direction relative to the sliding block 122, and an air cylinder can be installed on the sliding block 122 and can be a three-axis air cylinder which is used for driving the clamping block 123 to move up and down relative to the sliding block 122 in the vertical direction. During operation, the rodless cylinder can drive the sliding block 122 to move above the belt, then the three-shaft cylinder drives the clamping block 123 to move towards the belt to clamp the straight condition 41, finally the rodless cylinder starts the sliding block 122 to move above the bending mechanism 130, and the clamping block 123 releases the straight condition 41, so that the straight condition 41 is placed in the bending mechanism 130.

Referring to fig. 4, 6 and 7, the bending mechanism 130 is provided with a bending groove 134, and the bending groove 134 is substantially U-shaped, so that the shape of the bending groove 134 is matched with the shape of the bending member 42. The flex groove 134 provides a stop and guide for the formation of the flex member 42. Bending mechanism 130 includes a slide assembly 131, a drive assembly 132 and a release assembly 133, slide assembly 131 being used to clamp straight section 41 or release bending member 42. The transmission assembly 132 is used for driving the sliding assembly 131 to slide in the curved groove 134, the curved groove 134 defines a sliding track of the sliding assembly 131, the transmission assembly 132 can be a chain transmission assembly 132, and the sliding assembly 131 is fixed on a chain of the chain transmission assembly 132. The number of the unlocking assemblies 133 is two, the unlocking assemblies 133 may be air cylinders, the two unlocking assemblies 133 are respectively disposed at two ends of the bending groove 134, and when the acting force applied by the piston rods of the unlocking assemblies 133 is used for pressing the sliding assemblies 131, the sliding assemblies 131 are loosened to release the clamping on the bending member 42.

The sliding assembly 131 includes a base 131a, an elastic member 131b, a fixed block 131c, a swing block 131d, a rotation shaft 131e, and a guide shaft 131 f. The base 131a is fixed on the chain of the transmission assembly 132, and the base 131a is provided with a sliding slot, which is a curved slot. The guide shaft 131f is fixed to the swing block 131d, and both ends of the guide shaft 131f are slidably engaged with the slide grooves. The elastic member 131b may be a spring, one end of the elastic member 131b is fixed on the base 131a, and the other end of the elastic member 131b is fixed on the guide shaft 131f, i.e., the elastic member 131b is connected between the base 131a and the guide shaft 131 f. The rotating shaft 131e penetrates through the middle of the swinging block 131d and is rotatably connected with the base 131a, so that the swinging block 131d can swing back and forth relative to the base 131a, and the fixed block 131c is fixedly connected with the base 131 a. When the unlocking assembly 133 applies a pressing force to the guide shaft 131f, the guide shaft 131f moves in the sliding slot close to the fixed block 131c, and at this time, the elastic member 131b stores energy, so that the lower end of the swing block 131d moves away from the fixed block 131c around the rotating shaft 131e, so that the distance between the lower end of the swing block 131d and the fixed block 131c is increased, thereby enabling the sliding assembly 131 to play a role of loosening, i.e., the sliding assembly 131 is in a loosened state. When the unlocking assembly 133 cancels the pressing force applied to the guide shaft 131f, the guide shaft 131f is moved away from the fixed block 131c in the sliding slot by the elastic member 131b, and then the lower end of the swinging block 131d is moved close to the fixed block 131c around the rotating shaft 131e, so that the distance between the lower end of the swinging block and the fixed block 131c is reduced, and the sliding assembly 131 plays a role in clamping, that is, the sliding assembly 131 is in a clamping state.

For convenience of description, the two unlocking assemblies 133 are respectively referred to as a first unlocking assembly 133a and a second unlocking assembly 133 b. In operation, the chain-driven sliding assembly 131 of the transmission assembly 132 slides in the curved slot 134 to the first unlocking assembly 133a, the first unlocking assembly 133a releases the sliding assembly 131, and the clamping block 123 of the transfer mechanism 120 clamps the straight member 41, so that the end of the straight member 41 is located between the swinging block 131d and the fixed block 131 c. Then, when the first unlocking member 133a releases the pressing force applied to the guide shaft 131f, the sliding member 131 acts to clamp the end of the linear member 41 by the elastic member 131 b. Next, the clamping blocks 123 of the transfer mechanism 120 are released from the straight condition 41, and at this time, the clamping blocks 123 can still play a certain limiting role in the movement of the straight condition 41. Then, the chain of the transmission mechanism drives the sliding component 131 to move towards the second unlocking component 133b in the curved groove 134, and in the moving process of the sliding component 131, the sliding component 131 clamps the straight condition 41 and drags the straight condition 41, so that the straight condition 41 deforms along with the curved groove 134. When the sliding assembly 131 just moves to the second unlocking assembly 133b, the straight member 41 is bent to form the bending piece 42 matched with the shape of the bending groove 134, and at this time, the second unlocking assembly enables the sliding assembly 131 to loosen the bending piece 42, so that the formed bending piece 42 is smoothly transferred to the alignment device 200. In fig. 7, three sliding assemblies 131 are illustrated, only one of the sliding assemblies 131 is a functional assembly having an actual function, and the other two sliding assemblies 131 are illustrated as two positions that the functional assembly passes through during the movement.

Referring to fig. 4 and 9, in some embodiments, the alignment device 200 includes an alignment mechanism 210 and a rotation mechanism 220, and the alignment mechanism 210 is used for aligning the two bending members 42. The transfer mechanism 220 is used for buffering the bending member 42 from the aligning mechanism 210. After the bent piece 42 is aligned, the distance between the two straight segments 42a may be decreased, so that the distance between the two straight segments 42a after alignment is smaller than the distance between the two straight segments 42a before alignment.

Referring to fig. 10, in some embodiments, the first transfer device 300 may be a six-axis robot, and the first transfer device 300 may include a first jig 310, a second jig 320, a first substrate 330, and a second substrate 340. The first substrate 330 and the second substrate 340 are spaced apart, the number of the first clamps 310 may be at least two, for example, the number of the first clamps 310 is two, the two first clamps 310 are spaced apart on the first substrate 330, and both the two first clamps 310 are fixedly connected to the first substrate 330. The number of the second jigs 320 may be at least two, for example, the number of the second jigs 320 is two, the two second jigs 320 are spaced apart on the second substrate 340, the second jigs 320 are slidably coupled to the second substrate 340, and when the second jigs 320 slide with respect to the second substrate 340, the interval between the two second jigs 320 may be changed.

In operation, because the distance between the two straight segments 42a of the bending member 42 before alignment is relatively large, one of the first clamps 310 of the first transfer device 300 may be used to clamp one straight segment 42a, and the other first clamp 310 may be used to clamp the other straight segment 42a, so as to transfer the bending member 42 from the bending mechanism 130 to the alignment mechanism 210. After the alignment is completed, the mounting positions of the spiral ribs 42c on the two straight-line segments 42a are completely the same, when the distance between the two straight-line segments 42a is reduced, the distance between the two second clamps 320 can be changed to adapt to the distance between the two straight-line segments 42a after the alignment, one of the second clamps 320 clamps one straight-line segment 42a, the other second clamp 320 clamps the other straight-line segment 42a, and the aligned bent piece 42 is transferred from the alignment mechanism 210 to the transfer mechanism 220 for buffering.

Referring to fig. 3, 4 and 20, when the joint 43 is injection molded on the bent piece 42, one injection molding machine 20 may correspond to two molds 30, the two molds 30 are both slidably connected to the injection molding machine 20, the injection molding machine 20 has a first station 21, a second station 22 and an injection station 23, the injection station 23 is located between the first station 21 and the second station 22, and the two molds 30 may be respectively referred to as a first mold 31 and a second mold 32. In the initial position, the first die 31 is located at the first station 21 and the second die 32 is located at the second station 22. When the second transfer device 400 transfers one of the aligned bent pieces 42 from the transferring mechanism 220 to the first station 21, the end of the bent piece 42 is matched with the core rod 33 of the first mold 31 at the first station 21, then the first mold 31 drives the bent piece 42 to move from the first station 21 to the injection molding station 23, the injection molding machine 20 is opened and injects the melt into the first mold 31 to realize injection molding of the joint 43, after the joint 43 is molded, the first mold 31 is returned from the injection molding station 23 to the first station 21 to unload the bent piece 42 after the joint 43 is injected, so that the first station 21 is a loading and unloading station of the bent piece 42. Similarly, with respect to second mold 32, it is possible to refer to the operation mode of first mold 31, and when second mold 32 carries bending member 42 to move from second station 22 to injection station 23 and injection is completed, second mold 32 carries injection-completed bending and only returns from injection station 23 to second station 22 for unloading. Therefore, the first mold 31 and the second mold 32 are alternately operated to the injection station 23 for injection, so that the intermediate waiting time existing when the single mold 30 is operated is eliminated, and the work efficiency of injection molding can be improved.

Referring to fig. 11 and 12, the second transfer device 400 includes a fixed base 410, a first sliding base 420, a second sliding base 430, and a third clamp 440. The first sliding seat 420 is slidably connected to the fixed seat 410, and the first sliding seat 420 can slide along a first direction relative to the fixed seat 410 under the driving of the linear module, where the first direction is horizontal and transverse. The second sliding base 430 is slidably connected to the first sliding base 420, and the second sliding base 430 can slide along a second direction relative to the first sliding base 420 under the driving of the linear module, where the first direction is a horizontal direction and a longitudinal direction. The third clamp 440 is slidably connected to the second sliding seat 430, and the third clamp 440 can slide along a third direction relative to the second sliding seat 430 under the driving of the cylinder, where the third direction is a vertical direction, so that the first direction, the second direction, and the third direction are perpendicular to each other in space, thereby forming directions indicated by three coordinate axes in a spatial rectangular coordinate system. Therefore, the second transfer device 400 can enable the third clamp 440 to move in three directions, namely, the horizontal transverse direction, the horizontal longitudinal direction and the vertical direction, and the degree of freedom of movement of the third clamp 440 is improved. So that the third clamp 440 clamps the bent piece 42 from the middle rotating mechanism 220 and places the bent piece on the two molds 30 of the injection molding machine 20.

Referring to fig. 4, 13 and 20, in some embodiments, the number of shearing devices 500 is two, two shearing devices 500 are spaced apart, and one shearing device 500 is associated with each die 30. The shearing device 500 includes a clamping mechanism 510, a severing mechanism 520, and a trimming mechanism 530, the clamping mechanism 510 being positioned between the severing mechanism 520 and the trimming mechanism 530. The cutting mechanism 520 includes a mounting seat 521 and a cutting knife 522, the cutting knife 522 is slidably connected to the mounting seat 521, and when the cutting knife 522 slides downward relative to the mounting seat 521, the connection between the runner aggregate 50 and the mold 30 can be cut off. The cutting mechanism 530 includes two oppositely disposed shear blocks 531, and when the two shear blocks 531 move in the horizontal direction and approach each other, the two shear blocks 531 can cut off the connection between the runner aggregate 50 and the connector 43. In operation, for example, when the first mold 31 moves to the first station 21, the third clamp 440 of the second transfer device 400 clamps the bent part 42, and the clamping mechanism 510 of the shearing device 500 clamps the middle part of the runner aggregate 50, and then the cutter 522 cuts off the connection between one end of the runner aggregate 50 and the mold 30, and the shear 531 cuts off the connection between the other end of the runner aggregate 50 and the joint 43, so that the runner aggregate 50 is finally separated from the mold 30 and the joint 43. The removed runner congeals 50 can be discarded into a waste frame through the shearing device 500, the molded plastic hose product 40 with the runner congeals 50 cut off is placed into the blanking groove 901 through the third clamp 440, and under the action of gravity, the plastic hose product 40 slides down to a specified recovery position along the blanking groove 901.
