Description

Technical Field

[0001] The present invention relates to an automated device, and in particular, to an automatic plugging machine for lighting fixtures. Background Art

[0002] As Figure 1 shown, a plug includes a plug housing 90, a plug wire 91, and a plug core 92. The plug housing 90 is disposed between the plug wire 91 and the plug core 92 and connects and fixes the two. The plug housing 90 is usually formed by injection molding to ensure the connection strength between the plug wire 91 and the plug core 92.

[0003] In the existing injection molding equipment, when injecting, workers need to place and fix the plug core and the plug wire in the mold. The relative positions of the plug core and the plug wire with respect to the mold are relatively important, which determines whether the plug can be stably used subsequently. When the plug wire is long, after the plug core is placed in the mold, the overall displacement is likely to occur due to the gravity of the tail of the plug wire, and the positions of the plug core and the plug wire in the mold cannot be guaranteed. Moreover, the position of the plug wire is difficult to locate, and manual placement will result in low injection molding accuracy. Summary of the Invention

[0004] In view of this, the object of the present invention is to provide an automatic plugging machine for lighting fixtures, which has the advantage of high injection molding accuracy.

[0005] To solve the above technical problems, the technical solution of the present invention is: an automatic plugging machine for lighting fixtures, including an injection molding machine. A feeding structure is further provided at the front end of the injection molding machine. The feeding structure includes a frame and a material storage component, a material transfer component one, a fixing frame component, a material transfer component two, and a blanking component sequentially arranged on the frame. The material storage component is used to receive plug wires. The material transfer component one is used to send all the plug wires in the material storage component into the fixing frame component. The fixing frame component includes a frame body and a frame moving component. The frame body is used to fix a plurality of plug wires. The material transfer component two is used to send the frame body into and out of the injection molding machine. The frame moving component is used to drive the frame body to move between the material transfer component one, the material transfer component two, and the blanking component. The blanking component is used to remove the plug wires on the frame body.

[0006] By the above technical means, by providing a material storage component, a plurality of plug wires are installed in the material storage component, so as to perform injection molding on a plurality of plug wires at one time, increasing the injection molding efficiency. By providing a frame body and a frame moving component, the plug wires are fixed by the frame body, and the frame body and the plug wires are put into the injection molding machine together by the material transfer component two for injection molding, thereby ensuring the injection molding accuracy during injection molding.

[0007] Preferably, the material storage component includes a plurality of pneumatic chucks one. A clamping block is provided at the output end of the pneumatic chuck one. A clamping groove is formed on the clamping block, and the clamping groove matches the plug core.

[0008] Through the above technical means, the fixation of the plug core and the plug wire is achieved.

[0009] Preferably, the support moving assembly includes a motor, a conveyor roller, a conveyor belt and a mounting frame. The conveyor roller is arranged at the output end of the motor. The motor is fixedly arranged on the frame. The mounting frame is fixedly arranged on the conveyor belt. The motor drives the conveyor roller to rotate and drives the mounting frame to move. A positioning groove is formed on the mounting frame, and the support body is detachably arranged in the positioning groove.

[0010] Through the above technical means, through the cooperation of the motor and the conveyor belt, the mounting frame moves along with the conveyor belt, so as to transport the support body from the output end of the first material transfer assembly to the input end of the second material transfer assembly. By setting the positioning groove, the support body is accurately mounted on the mounting frame.

[0011] Preferably, a wire clamping block and a positioning head are arranged in the support body. The positioning head is used for mounting the plug core. A wire clamping groove is formed in the support body. The wire clamping block is arranged in the wire clamping groove and cooperates with the wire clamping groove to clamp the plug wire. The fixed frame assembly further includes a wire inserting assembly, and the wire inserting assembly is used for inserting the plug core into the positioning head. A clamping assembly is further arranged at the side end of the first material transfer assembly, and the clamping assembly is used for controlling the wire clamping block to clamp the plug wire.

[0012] Through the above technical means, by setting the wire clamping block and the positioning head, and by setting the wire inserting assembly and the clamping assembly, the fixation of the plug wire and the plug core is achieved, so as to prevent the position of the plug wire from shifting during injection molding, resulting in a decrease in injection molding accuracy.

[0013] Preferably, the clamping assembly includes a first cylinder arranged on the first material transfer assembly and an inclined ejector block I arranged at the output end of the first cylinder. An inclined moving groove is further arranged at the bottom of the wire clamping groove. A sliding block is arranged at the bottom of the wire clamping block, and the sliding block is slidably arranged in the inclined moving groove. An inclined top surface I is arranged at the side end of the wire clamping block, and an inclined top surface II is arranged on the inclined ejector block I. When the inclined ejector block I moves downward and the inclined top surface II abuts against the inclined top surface I, the wire clamping block moves and abuts against the plug wire.

[0014] Through the above technical means, through the cooperation between the inclined top surface I and the inclined top surface II, when it is necessary to clamp the plug wire, the first cylinder is driven to drive the inclined ejector I to move downward, and the wire clamping block can be pushed to complete the clamping.

[0015] Preferably, an avoidance groove is further provided in the frame body, and the wire inserting assembly is arranged in the avoidance groove. The wire inserting assembly includes a wire inserting block, a second cylinder, and a third cylinder. The second cylinder is fixedly arranged on the frame and arranged along the Y-axis direction. The third cylinder is arranged at the output end of the second cylinder and arranged along the Z-axis direction. The wire inserting block is arranged at the output end of the third cylinder. The third cylinder is used to drive the wire inserting block to move into or out of the frame body. A forming groove adapted to the plug core is formed in the wire inserting block. When the second cylinder drives the third cylinder and the wire inserting block to move, the forming groove pushes the plug core into the positioning head, and at the same time, the plug wire tightens the clamping block.

[0016] By the above technical means, through the cooperation of the second cylinder and the third cylinder, the plug core enters the wire inserting block, so as to position the plug core. Through the action of horizontally pulling the plug core, the plug wire continues to move horizontally for a certain distance. Through the friction force between the rubber of the plug wire and the clamping block, the plug wire drives the clamping block to continue to move a certain distance along the inclined moving groove, so that the clamping block further clamps the plug wire, increasing the clamping force of the plug wire. At the same time, through the deformability of the rubber and the generation of a certain reaction force, the clamping block will not fall off easily.

[0017] Preferably, the first material moving assembly has the same structure as the blanking assembly. The first material moving assembly includes an XZ-axis driving assembly and a plurality of pneumatic clamping jaws. The pneumatic clamping jaws are used to clamp the plug wire. A wire loosening assembly is arranged at the side end of the blanking assembly. The wire loosening assembly includes a fourth cylinder and an inclined ejector block two. An inclined top surface two is arranged on the opposite side of the clamping block relative to the inclined top surface one. When the inclined ejector block two abuts against the inclined top surface two, the clamping block loosens the plug wire.

[0018] By the above technical means, by arranging a wire loosening assembly at the side end of the blanking assembly, the clamping block is pushed out in the reverse direction after the injection molding is completed, so that the plug wire can be taken out from the clamping wire groove.

[0019] Preferably, the second material moving assembly includes a clamping arm arranged in the injection molding machine. A second pneumatic chuck is arranged at the output end of the clamping arm. The second pneumatic chuck is used to clamp the frame body. The clamping arm drives the frame body to move into or out of the injection molding machine.

[0020] By the above technical means, the frame body is sent into or out of the injection molding machine through the cooperation of the clamping arm and the chuck, realizing the feeding and discharging functions during injection molding. Description of the Drawings

Detailed implementation manners

[0023] The following further details the specific implementation manners of the present invention in conjunction with the accompanying drawings, so that the technical solutions of the present invention are easier to understand and master.

[0024] An automatic plug - inserting machine for lighting fixtures includes an injection molding machine 1. A feeding structure is further provided at the front end of the injection molding machine 1. The feeding structure includes a frame 2 and a material storage assembly 3, a material transfer assembly one 4, a fixing frame assembly 5, a material transfer assembly two 6, and a blanking assembly 7 that are sequentially arranged on the frame 2. The material storage assembly 3 is used to receive the plug wires 91. The material transfer assembly one 4 is used to send all the plug wires 91 in the material storage assembly 3 into the fixing frame assembly 5. The fixing frame assembly 5 includes a frame body 8 and a frame moving assembly 9. The frame body 8 is used to fix a plurality of plug wires 91. The material transfer assembly two 6 is used to send the frame body 8 into and out of the injection molding machine 1. The frame moving assembly 9 is used to drive the frame body 8 to move between the material transfer assembly one 4, the material transfer assembly two 6, and the blanking assembly 7. The blanking assembly 7 is used to remove the plug wires 91 on the frame body 8.

[0025] The material storage component 3 includes eight pneumatic chucks I 10. A clamping block 11 is arranged at the output end of the pneumatic chuck I 10. A clamping groove 12 is formed on the clamping block 11, and the clamping groove 12 is matched with the plug core 92. Before injection molding, feeding is carried out by workers or mechanical clamping claws. The plug core 92 and the plug wire 91 are sequentially inserted into the clamping block 11 and clamped, so as to realize the functions of storing materials and discharging materials. At the same time, by arranging the clamping groove 12, the plug core 92 can be pressed against the end of the plug wire 91 in a clamping manner through the clamping groove 12, playing a stamping function.

[0026] The first material transfer component 4 includes an XZ-axis driving component 13 and several pneumatic clamping claws 14. The XZ-axis driving component 13 is fixedly arranged on the frame 2 and is composed of a lead screw motor and a linear cylinder. The pneumatic clamping claws 14 are all arranged on a substrate and are used to clamp the plug wire 91 and send the plug wire 91 into the frame body 8.

[0027] The frame moving component 9 includes a motor 15, a pair of conveyor rollers 16, a conveyor belt 17 and a mounting frame 18. The conveyor roller 16 is arranged at the output end of the motor 15. The motor 15 is fixedly arranged on the frame 2. The conveyor belt 17 is wound around the two conveyor rollers 16. The mounting frame 18 is fixedly arranged on the conveyor belt 17. The motor 15 drives the conveyor roller 16 to rotate and drives the mounting frame 18 to move. A positioning groove 19 is formed on the mounting frame 18. The frame body 8 is detachably arranged in the positioning groove 19. By arranging the positioning groove 19, the frame body 8 is accurately installed on the mounting frame 18.

[0028] A wire clamping block 20 and a positioning head 21 are arranged in the frame body 8. The positioning head 21 is used to install the plug core 92. A wire clamping groove 22 is formed in the frame body 8. The wire clamping block 20 is arranged in the wire clamping groove 22 and cooperates with the wire clamping groove 22 to clamp the plug wire 91. The injection molding area is between the wire clamping block 20 and the positioning head 21. The injection molded plug housing 90 needs to wrap the connection part between the plug core 92 and the plug wire 91. The fixed frame component 5 further includes a wire inserting component 24. The wire inserting component 24 is arranged between the wire clamping block 20 and the positioning head 21 and is used to insert the plug core 92 into the positioning head 21. A clamping component 23 is further arranged at the side end of the first material transfer component 4. The clamping component 23 is used to control the wire clamping block 20 to clamp the plug wire 91. By arranging the wire inserting component 24 and the clamping component 23, the fixing of the plug wire 91 and the plug core 92 is realized, so as to prevent the position of the plug wire 91 from shifting during injection molding, resulting in a decrease in injection molding accuracy.

[0029] The clamping assembly 23 includes a first cylinder 25 arranged on the first material transfer assembly 4 and a first inclined ejector block 26 arranged at the output end of the first cylinder 25. A slanting moving groove 27 is further arranged at the bottom of the wire clamping groove 22. A sliding block 28 is arranged at the bottom of the wire clamping block 20. The sliding block 28 is slidably arranged in the slanting moving groove 27. The slanting moving groove 27 is in a left-right inclined state. A first inclined top surface 29 is arranged at the side end of the wire clamping block 20. A second inclined top surface 30 is arranged on the first inclined ejector block 26. When the first cylinder 25 drives the first inclined ejector block 26 to move downward and the second inclined top surface 30 abuts against the first inclined top surface 29, the wire clamping block 20 moves along the slanting moving groove 27, and the distance between the wire clamping block 20 and the wire clamping groove 22 is reduced, so that the wire clamping block 20 abuts against the plug wire 91.

[0030] An avoidance groove 31 is further arranged between the wire clamping block 20 and the positioning head 21. The wire inserting assembly 24 is arranged in the avoidance groove 31. The wire inserting assembly 24 includes a wire inserting block 32, a second cylinder 33 and a third cylinder 34. The second cylinder 33 is fixedly arranged on the frame 2 and arranged along the Y-axis direction. The third cylinder 34 is arranged at the output end of the second cylinder 33 and arranged along the Z-axis direction. The wire inserting block 32 is arranged at the output end of the third cylinder 34. The third cylinder 34 is used for driving the wire inserting block 32 to move into or out of the frame body 8. A forming groove 35 adapted to the plug core 92 is formed in the wire inserting block 32. When the second cylinder 33 drives the third cylinder 34 and the wire inserting block 32 to move, the forming groove 35 pushes the plug core 92 into the positioning head 21. At the same time, the plug wire 91 tightens the wire clamping block 20. Through the cooperation of the second cylinder 33 and the third cylinder 34, the plug core 92 enters the wire inserting block 32, so as to position the plug core 92. Through the action of horizontally pulling the plug core 92, the plug wire 91 continues to move horizontally for a certain distance. Through the friction force between the rubber of the plug wire 91 and the wire clamping block 20, the plug wire 91 drives the wire clamping block 20 to continue to move a certain distance along the slanting moving groove 27, so that the wire clamping block 20 further clamps the plug wire 91 and makes the plug wire 91 relatively straightened. When using this structure, the clamping force of the wire clamping block 20 needs to be reduced when the plug wire 91 is clamped for the first time, so as to prevent the problem that the plug wire 91 breaks when the plug wire 91 is pulled to achieve the second clamping. After clamping, a certain reaction force can be generated through the elasticity of the rubber, so that the wire clamping block 20 will not fall off easily.

[0031] The material transfer component 14 has the same structure as the blanking component 7. A wire loosening component 36 is provided at the side end of the blanking component 7. The wire loosening component 36 includes a cylinder four 37 and an inclined ejector block two 38. The wire loosening component 36 has the same structure as the clamping component. The difference is that the inclined ejector block one 26 and the inclined ejector block two 38 are symmetrically arranged. An inclined top surface two 30 is provided on the opposite side of the clamping block 20 relative to the inclined top surface one 29. When the inclined ejector block two 38 abuts against the inclined top surface two 30, the clamping block 20 releases the plug wire 91. The material transfer component two 6 includes a clamping arm 39 provided in the injection molding machine 1. A pneumatic chuck two 41 is provided at the output end of the clamping arm 39. The clamping arm 39 can move in the Y-axis direction and the Z-axis direction, which is prior art and will not be shown in detail here. The pneumatic chuck two 41 is used to clamp the frame 8. The clamping arm 39 drives the frame 8 to move into or out of the injection molding machine 1 to realize the loading and unloading function during injection molding.

[0032] Of course, the above are only typical examples of the present invention. In addition, the present invention can also have many other specific implementation manners. Any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection required by the present invention.
