Description

Technical Field

[0001] The present invention relates to the field of production equipment for wire harness connectors, and particularly to a semi-automatic blind plug pressing mechanism. Background Art

[0002] In the production of automotive electrical products such as wire harnesses, the wire harness often needs to pass through or be connected to a wire harness connector. During this process, in order to facilitate the passing of the wire harness, the through-hole diameter of the wire harness connector is larger than the diameter of the wire harness, which will result in gaps in these holes. In order to block these holes and make the wire harness connector better waterproof, dustproof, and oil-proof, blind plugs are added to these holes for blocking.

[0003] The installation of blind plugs is generally to press the blind plugs into the holes through a pressing mechanism. Since multiple blind plugs are often pressed into a wire harness connector, when workers perform the pressing, there are often situations where they are distracted due to taking the blind plugs and forget the installation sequence and the number of installations, resulting in missed installation of blind plugs, which has a great impact on product quality and production efficiency.

[0031] 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 making creative efforts belong to the scope of protection of the present invention.

[0032] Please refer to Figures 1 to 6, the present invention provides a technical solution: a semi-automatic blind bolt press-fitting mechanism, which includes a fixed base 1. A vertical plate 2 is provided on the fixed base 1. The bottom of the vertical plate 2 is fixed on the fixed base 1. A vertical press-fitting assembly 3 is provided on the vertical plate 2. The vertical press-fitting assembly 3 is used for manually press-fitting the blind bolt 100. An installation tooling 4 is provided directly below the vertical press-fitting assembly 3. The installation tooling 4 is used to fix the wire harness connector of the blind bolt 100 to be press-fitted. A protective cover 5 is provided on the side of the installation tooling 4. The protective cover 5 is hermetically connected to the installation tooling 4. A sealing film device 6 and a blind bolt conveying device 7 are provided inside the protective cover 5. The sealing film device 6 is electrically connected to the blind bolt conveying device 7 through a contact switch. The blind bolt conveying device 7 is used to send out the blind bolts 100 for press-fitting.

[0033] In this embodiment, a card slot 21 is provided on the side of the vertical plate 2. The card slot 21 is used to fix the sliding groove 73.

[0034] In this embodiment, the vertical press-fitting assembly 3 includes a straight elbow clamp 31, a vertical guide rail 32, a wear-resistant part 33, and a downward pressing part 34. The straight elbow clamp 31 is installed at the upper end of the vertical plate 2 and is located above the wear-resistant part 33 and the downward pressing part 34. The vertical guide rail 32 is installed on the side of the vertical plate 2. The wear-resistant part 33 is slidably connected to the vertical guide rail 32. The downward pressing part 34 is installed on the wear-resistant part 33 through bolts. The top of the downward pressing part 34 is connected to the output end of the straight elbow clamp 31. By manually pressing down the straight elbow clamp 31 with the right hand of the worker, the downward pressing part 34 is driven to move downward, and the blind bolt 100 is pressed into the wire harness connector.

[0035] In this embodiment, the installation tooling 4 includes a fixing plate 41 and a base plate 42. The fixing plate 41 is fixedly connected to the base plate 42 and is hermetically connected. The fixing plate 41 is provided with a positioning hole 43 for installing the wire harness connector. A sealing ring 44 is provided in the positioning hole 43. The base plate 42 is fixed on the fixed base 1. Multiple exhaust grooves 45 are provided at the position corresponding to the positioning hole 43 on the base plate 42. The exhaust grooves 45 communicate with the protective cover 5. On the other side of the fixing plate 41 and the base plate 42 symmetric to the protective cover 5, a blocking plate 46 is provided. The blocking plate 46 is fixed on the fixing plate 41 and the base plate 42. The shape of the positioning hole 43 is processed according to the wire harness connector used, and different fixing plates 41 are replaced as needed. The wire harness connector placed in the positioning hole 43 will form a sealed space in the positioning hole 43 due to the sealing effect of the sealing ring 44, so that the gas in the wire harness connector can only be discharged to the outside through the exhaust grooves 45.

[0036] In this embodiment, pressing plates 51 are provided at both ends of the protective housing 5. The protective housing 5 is fixed to the side of the installation tooling 4 through the pressing plates 51 at both ends. The roots of the pressing plates 51 are inserted into the fixing plate 41 and the base plate 42 to provide positioning for the fixing plate 41 and the base plate 42.

[0037] In this embodiment, the sealing film device 6 includes a sealing film 61, a sealing frame 62, a first contact piece 63 and a second contact piece 64. The sealing film 61 is installed and tensioned in the sealing frame 62. The sealing frame 63 is located between the installation tooling 4 and the protective housing 5 and is in sealed connection with both of them. The first contact piece 63 is installed on the sealing film 61, and the second contact piece 64 is fixed on the sealing frame 62. The first contact piece 63 and the second contact piece 64 can energize the blind bolt conveying device 7 when they are connected. When the pressing member 34 quickly presses down, the blind bolt 100 will be pressed into the corresponding holes of the wire harness connector. The original air in these holes will be discharged through the exhaust groove 45 due to the quick pressing and gather at the sealing film 61 and then squeeze the sealing film 61, which will cause the sealing film 61 to deform, making the first contact piece 63 and the second contact piece 64 connected and energizing the electric push rod 72.

[0038] In this embodiment, the blind bolt conveying device 7 includes a conveying slider 71, an electric push rod 72 and a chute 73. Guide ribs 74 are provided on both sides of the conveying slider 71. The conveying slider 71 is slidably connected in the protective housing 5 through the guide ribs 74. A blind bolt groove 75 is provided in the conveying slider 71. The conveying slider 71 is connected to the output shaft of the electric push rod 72 through the connecting handle 76 below. The electric push rod 72 is fixed in the protective housing 5. The chute 73 is inclined. The upper end of the chute 73 is fixed in the card slot 21, and the lower end of the chute 73 is located at the blind bolt groove 75. A positioning block 77 is further provided at the end of the conveying slider 71, and the positioning block 77 is fixed in the protective housing 5. The electric push rod 72 can drive the conveying slider 71 to move out of the protective housing 5, so that the blind bolt 100 located in the blind bolt groove 75 can move out of the protective housing 5. Since the length of the blind bolt 100 is greater than that of the blind bolt groove 75, and one side of the blind bolt groove 75 is open and the other three sides are inclined planes, the blind bolt 100 falling from the chute 73 will fall to the lowest point of the blind bolt groove 75 and be driven out by the conveying slider 71. In order to ensure that one blind bolt 100 falls each time, a limit can be added to the chute 73. During the forward movement of the conveying slider 71, since the moving-out stroke is small and the length of the conveying slider 71 is long, it will hold the blind bolt 100 falling from the chute 73, so that it can fall into the blind bolt groove 75 after the conveying slider 71 is reset. The chute 73 is connected to the external blind bolt storage and conveying device.

[0039] In this embodiment, a contact 81 is provided at the upper end of the wear-resistant member 33, and a contact piece 82 is provided directly above the contact 81. The contact 81 and the contact piece 82 are electrically connected to the electric push rod 72. After the pressing is completed and the blind plug 100 is taken away, the straight elbow clamp 31 is lifted, the contact 81 rises to contact the contact piece 82. At the same time, the gas squeezing the sealing film 61 dissipates, the electric push rod 72 is powered off, and then is controlled to be powered on after being connected by the contact 81 and the contact piece 82, so that the electric push rod 72 moves in the reverse direction, the conveying slider 71 is reset, and another dropped blind plug 100 is received to start the next working cycle.

[0040] Working principle: During use, first, a wire harness connector is placed in the positioning hole 43, and the position below the sealing ring 44 is sealed through the sealing ring 44. Then, the worker manually presses down the straight elbow clamp 31 with the right hand, driving the downward pressing member 34 to move downward, and pressing the blind plug 100 into the wire harness connector. When the downward pressing member 34 quickly presses down, the blind plug 100 will be pressed into the corresponding hole of the wire harness connector, and the original air in these holes will be discharged through the exhaust groove 45 due to the quick pressing and gather at the sealing film 61 and then squeeze the sealing film 61, which will cause the sealing film 61 to deform, making the contact piece one 63 and the contact piece two 64 connected, and powering on the electric push rod 72. The electric push rod 72 can drive the conveying slider 71 to move out of the protective cover 5, so that the blind plug 100 located in the blind plug groove 75 can move out of the protective cover 5. The worker takes the blind plug 100 with the left hand. After the pressing is completed and the blind plug 100 is taken away, the straight elbow clamp 31 is lifted, the contact 81 rises to contact the contact piece 82. At the same time, the gas squeezing the sealing film 61 dissipates, the electric push rod 72 is powered off, and then is controlled to be powered on after being connected by the contact 81 and the contact piece 82, so that the electric push rod 72 moves in the reverse direction, the conveying slider 71 is reset, and another dropped blind plug 100 is received to start the next working cycle.

[0041] Based on the above, the present invention can realize that after each blind plug is pressed and installed, another blind plug is sent out through the blind plug conveying device, and only one blind plug is sent out each time, which is convenient for the worker to take and can ensure that each blind plug can be installed into the wire harness connector to prevent missing installation.

[0042] As is known by technical common sense, the present invention can be implemented by other embodiments without departing from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and are not the only ones. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
