[0001] The present invention relates to the technical field of trimming devices for the production and processing of electrical connectors, and particularly to a housing trimming device for the production and processing of electrical connectors. Background Art

[0002] In the production process of electrical connectors, it is necessary to separately produce housings, terminals, and contacts, and finally automate the assembly of the housing and terminals into electrical connectors. In the production process, different materials of housings need to be produced according to different types of electrical connectors, usually including metal housings, plastic housings, and composite material housings.

[0003] In the housing production process, whether it is the stamping process of metal housings or the injection molding process of plastic housings, the housing needs to be trimmed after production to meet the process requirements of electrical connectors. However, when trimming the housing, traditional single-stage negative pressure adsorption is difficult to completely recycle the waste generated during trimming, resulting in some waste being adsorbed on the surface of the housing, causing environmental pollution. At the same time, when trimming composite housings, the waste generated includes metal chips, plastic scraps, and mixed waste, which are difficult to separate, resulting in difficult waste recycling, low recovery rate, and low reuse rate.

[0004] In view of this, we propose a housing trimming device for the production and processing of electrical connectors. Summary of the Invention

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1-9 , a trimming device for the outer shell of an electrical connector during production and processing, including a conveyor belt 1 and a trimming frame 2 installed on the conveyor belt 1. A cutting knife and a grinding belt are installed inside the trimming frame 2 for cutting and grinding the outer shell of the electrical connector, so that the outer shell of the electrical connector meets the production requirements. Both ends of the trimming frame 2 are fixedly installed with shielding curtains 3. The shielding curtains 3 are made of soft materials, which can shield the inside of the trimming frame 2 while not blocking the entry of the outer shell, and prevent fine powder waste generated by grinding from entering the environment and posing a safety hazard to the staff.

[0038] A blowing mechanism 4 is arranged on the trimming frame 2 for cooling the cutting and grinding areas when trimming and grinding the outer shell, so as to reduce the incomplete grinding caused by the softening of burrs due to the temperature rise of the thermoplastic material caused by friction. The blowing mechanism 4 can also blow the outer shell after grinding to directionally remove the waste generated by grinding and prevent the waste from contaminating the surface of the outer shell.

[0039] A swinging mechanism 5 is also arranged on the trimming frame 2 for controlling the wind direction of the blowing mechanism 4, so as to avoid the occurrence of an air flow blind area caused by a single-direction air flow when removing waste from the outer shell. The continuously changing air flow can better and more thoroughly remove waste from objects with irregular shapes or uneven surfaces.

[0040] A recycling mechanism 6 is arranged at the bottom of the conveyor belt 1 for recycling the waste generated by trimming and separating the recycled waste for convenient later recycling.

[0041] Please refer to Figures 1-3 , the blowing mechanism 4 includes a blow pipe 41. The blow pipe 41 is a three-way pipe. One end of the blow pipe 41 is connected to a blower, and the other two ends of the blow pipe 41 are respectively connected to a cooling chamber 42 and a high-voltage generator 45.

[0042] The cooling chamber 42 is used to cool the air, preferably by dry ice cooling. The cooling chamber 42 is connected to a cooling pipe 44 through a pressure pump 43. The cooling pipe 44 is used for air-cooling during the trimming of the outer shell. The pressure pump 43 is used to adjust the wind speed of the air-cooling, so that the working surface of the outer shell can be air-cooled during the trimming of the outer shell.

[0043] The high-voltage generator 45 can generate a large number of positive ions. The high-voltage generator 45 is fixedly installed on the trimming frame 2. At the bottom end of the high-voltage generator 45 inside the trimming frame 2, a blowing plate 46 is fixedly installed. A plurality of fixed nozzles 47 are fixedly installed around the bottom end of the blowing plate 46. At the middle position of the bottom end of the blowing plate 46, a plurality of movable nozzles 48 are fixedly installed through a hose. The plurality of fixed nozzles 47 and movable nozzles 48 are both arranged in an array. The nozzle openings of the fixed nozzles 47 are vertically downward, so that the plurality of arrayed fixed nozzles 47 form an air curtain around the blowing plate 46, which can effectively prevent waste materials from detaching from the trimming frame 2. The plurality of arrayed movable nozzles 48 can better remove the waste materials on the shell. The ions generated by the high-voltage generator 45 can eliminate the static electricity on the surface of the shell, avoiding the problem that fine powder waste materials are adsorbed on the shell due to static electricity adsorption and cannot be removed.

[0044] The fan drives the air flow through the air blowing pipe 41. A part of the air flow enters the cooling chamber 42 through the air blowing pipe 41 for cooling, and then is pressurized by the pressure pump 43 to control the flow rate of the air flow. Finally, the trimming area is air-cooled through the cooling pipe 44 to enhance the trimming effect. Another part of the air flow enters the blowing plate 46 through the high-voltage generator 45 and is blown through the fixed nozzles 47 and movable nozzles 48, so that the air flow contains ions to remove the static electricity adsorption on the shell and avoid the problem that waste materials are difficult to remove due to static electricity adsorption.

[0045] Please refer to Figures 4-7 , the swing mechanism 5 includes electric push rods 51. The electric push rods 51 are fixedly installed on both sides of the trimming frame 2. The electric push rods 51 are fixedly connected to sliding rods 55. Sliding grooves 54 are fixedly opened on both sides of the trimming frame 2. The sliding rods 55 are slidably connected with the sliding grooves 54. Inner protective shells 53 and outer protective shells 52 are fixedly installed on the inner and outer sides of the trimming frame 2 at the positions of the sliding grooves 54 respectively, for preventing waste material leakage.

[0046] A rack 56 is fixedly opened at the bottom end on one side of the sliding rod 55. The movable nozzles 48 are fixedly connected through a connecting rod 57. The connecting rod 57 is rotatably connected with the inner protective shell 53. Gears 58 are fixedly installed at both ends of the connecting rod 57. The gears 58 are meshed with the rack 56.

[0047] By starting the electric push rod 51, the electric push rod 51 drives the sliding rod 55 to reciprocate along the chute 54. When the sliding rod 55 reciprocates, through the meshing effect between the rack 56 and the gear 58 arranged on the sliding rod 55, the gear 58 is driven to rotate reciprocally. The reciprocal rotation of the gear 58 drives the connecting rod 57 to rotate reciprocally, and the reciprocal rotation of the connecting rod 57 drives the movable spray head 48 to rotate reciprocally. The reciprocal rotation of the movable spray head 48 causes the angle of the airflow sprayed by the movable spray head 48 to change continuously. The continuous change of the airflow can improve the cleaning effect on the waste on the surface of the housing.

[0048] Please refer to Figures 8-9 , the recycling mechanism 6 includes a plurality of through grooves 61 which are opened on the conveyor belt 1. The plurality of through grooves 61 are arranged in an array. The bottom end of the trimming frame 2 is fixedly connected with an adsorption seat 62. The adsorption seat 62 is located at the bottom end of the conveyor belt 1. The bottom end of the adsorption seat 62 is fixedly connected with a conveying pipe 63. The conveying pipe 63 is connected with a centrifuge 64. The centrifuge 64 is provided with a first discharge port 641 and a second discharge port 642.

[0049] When the trimming device is working, when trimming the housing, the cooling pipe 44 will blow the housing, blowing some waste onto the conveyor belt. When the trimming is completed, the housing will pass through the fixed spray head 47 for downward blowing and the swinging blowing of the movable spray head 48. And the airflow contains positive ions which can eliminate static adsorption, so that the waste on the housing can be completely removed. And the airflow can blow the waste off the conveyor belt 1 and into the adsorption seat 62 through the through grooves 61.

[0050] The waste enters the centrifuge 64 through the adsorption seat 62 and the conveying pipe 63. Through the centrifugal action of the centrifuge 64, the metal chips are discharged through the first discharge port 641, and the plastic particles are discharged through the second discharge port 642. Thus, the separation and recycling of the metal chips and plastic particles are achieved, reducing material waste.

[0051] A housing trimming device for the production and processing of electrical connectors, its working principle is as follows:

[0052] The housing is conveyed through the conveyor belt 1 and then enters the trimming frame 2 through the shielding curtain 3 for trimming. Start the fan, the fan drives the airflow through the air blowing pipe 41. A part of the airflow enters the cooling chamber 42 through the air blowing pipe 41 for cooling, and then is pressurized by the pressure pump 43 to control the flow rate of the airflow. Finally, the trimming part is air-cooled through the cooling pipe 44 to enhance the trimming effect. Another part of the airflow enters the blowing plate 46 through the high-voltage generator 45 and is blown through the fixed spray head 47 and the movable spray head 48, so that the airflow contains positive ions. The positive ions are used to eliminate the static electricity on the surface of the housing, avoiding the problem that the waste is difficult to remove due to static adsorption.

[0053] Meanwhile, the electric push rod 51 is activated. The electric push rod 51 drives the sliding rod 55 to reciprocate along the sliding groove 54. When the sliding rod 55 reciprocates, through the meshing effect between the rack 56 provided on the sliding rod 55 and the gear 58, the gear 58 is driven to rotate reciprocally. The reciprocal rotation of the gear 58 drives the connecting rod 57 to rotate reciprocally. The reciprocal rotation of the connecting rod 57 drives the movable spray head 48 to rotate reciprocally. The reciprocal rotation of the movable spray head 48 causes the angle of the airflow ejected by the movable spray head 48 to change continuously, making the cleaning effect of the movable spray head 48 on the housing better.

[0054] The waste materials that fall during trimming and the waste materials blown off by the fixed spray head 47 and the movable spray head 48 enter the adsorption seat 62 through the through groove 61 on the conveyor belt 1. The waste materials enter the centrifuge 64 through the adsorption seat 62 via the conveying pipe 63. Through the centrifugal action of the centrifuge 64, the metal chips are discharged through the first discharge port 641, and the plastic particles are discharged through the second discharge port 642. Thus, the separation and recovery of the metal chips and the plastic particles are achieved, reducing material waste.
