Description

Technical Field

[0001] The utility model relates to the technical field of wire harness production equipment, in particular to a rubber cover machine for notebook wire harness production. Background Art

[0002] Laptop wiring harnesses refer to the wiring harnesses used to connect the various components inside a laptop computer. They mainly include wires, connectors, plugs and other components. These wiring harnesses play a vital role in laptop computers, ensuring data transmission and power supply between various components. During the production of laptop wiring harnesses, in order to better protect the wiring harnesses, they need to be covered with rubber sleeves.

[0003] At present, in the process of putting the rubber sleeve on the outer surface of the laptop wiring harness, since both the wiring harness and the rubber sleeve are relatively soft, and the inner size of the rubber sleeve is slightly smaller than the outer size of the entire wiring harness, the elasticity of the rubber sleeve allows it to better adhere to the outer surface of the wiring harness. Therefore, the rubber sleeve cannot be easily put on the outer surface of the laptop wiring harness. For this reason, we propose a rubber sleeve machine for notebook wiring harness production. Utility Model Content

[0004] The purpose of the utility model is to provide a rubber sleeve machine for producing notebook wire harnesses, which has the ability to expand the rubber sleeve before sleeve application to increase its internal size, so that the rubber sleeve can be conveniently sleeved on the outer surface of the notebook wire harness, thereby improving the sleeve application efficiency. It solves the current problem that in the process of sleeve application on the outer surface of the notebook wire harness, the wire harness and the rubber sleeve are both relatively soft, and the internal size of the rubber sleeve is slightly smaller than the overall external size of the wire harness, and the elasticity of the rubber sleeve makes it better adhere to the outer surface of the wire harness, so the rubber sleeve cannot be conveniently sleeved on the outer surface of the notebook wire harness.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rubber cover machine for notebook wire harness production, comprising a fixed base plate, an air pump and a movable expansion plate, wherein fixed vertical plates are symmetrically fixedly installed at both sides of the upper surface of the fixed base plate, cylinders are fixedly installed on the outer sides of the two fixed vertical plates, and the output ends of the two cylinders are fixedly connected to the movable expansion plate, the front and rear surfaces of the two movable expansion plates are provided with curved portions, and the inner sides of the four curved portions are provided with a number of adsorption holes at equal distances, and the input end of the air pump is connected to the interior of the movable expansion plate.

[0006] Preferably, the input end of the vacuum pump is fixedly connected to a three-way valve, the remaining two ends of the three-way valve are respectively fixedly connected to an air inlet pipe and a connecting air pipe, the end of the connecting air pipe is fixedly connected to an air extraction hose, and the two ends of the air extraction hose are respectively fixedly connected to the lower surfaces of the two movable expansion plates.

[0007] Preferably, mounting holes are provided on the upper surface of the fixed base plate near the four corners.

[0008] Preferably, sealing rubber strips are fixedly installed on the inner sides of the four curved portions.

[0009] Preferably, sliding sleeves are symmetrically fixedly installed on the outer sides of the two fixed vertical plates near the upper surface and the lower surface, and sliding rods are symmetrically fixedly connected on the outer sides of the movable expansion plates near the upper surface and the lower surface, and the four sliding rods pass through four sliding sleeves respectively.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] 1. The utility model achieves the effect of expanding the rubber sleeve before sleeve installation to increase its internal size by arranging a fixed bottom plate, a fixed vertical plate, an air cylinder, a movable expansion plate, a bent portion, an adsorption hole and an air pump, so as to enable the rubber sleeve to be expanded before installation to increase its internal size, so that the rubber sleeve can be conveniently installed on the outer surface of the notebook wiring harness, thereby improving the installation efficiency. The rubber sleeve is placed between the two movable expansion plates, and the two cylinders drive the two movable expansion plates to move towards each other, and make the movable expansion plates and the bent portion contact the outer surface of the rubber sleeve. Then the air pump works to extract the air inside the movable expansion plate, and the rubber sleeve is adsorbed on the bent portion through the adsorption hole. The two cylinders drive the two movable expansion plates to move in opposite directions, so that the rubber sleeve can be expanded to increase its internal size. Then the notebook wiring harness is inserted into the rubber sleeve, and the two cylinders drive the two movable expansion plates to move towards each other, and at the same time remove the adsorption of the adsorption hole on the rubber sleeve, and the rubber sleeve is installed on the outer surface of the wiring harness.

[0012] 2. The utility model can seal the gap between the bent portion and the rubber sleeve by providing a sealing rubber strip, so that the bent portion can better adsorb the rubber sleeve through the adsorption hole.

[0013] 3. The present invention can support the mobile expansion board by providing the sliding rod and the sliding sleeve, and also guide the movement of the mobile expansion board, thereby improving the stability of the mobile expansion board. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] like Figures 1-4 As shown, the utility model proposes a rubber cover machine for notebook wiring harness production, comprising a fixed base plate 1, an air pump 2 and a movable expansion plate 4. The upper surface of the fixed base plate 1 is provided with mounting holes 9 near the four corners. Bolts pass through the mounting holes 9 to fix the fixed base plate 1 in the use position. Fixed vertical plates 5 are symmetrically fixedly installed on both sides of the upper surface of the fixed base plate 1. Cylinders 8 are fixedly installed on the outer sides of the two fixed vertical plates 5, and the output ends of the two cylinders 8 are fixedly connected to the movable expansion plate 4. The front and rear surfaces of the two movable expansion plates 4 are provided with bending parts 10. The movable expansion plate 4 and the bending part 10 are hollow inside, and the bending part 10 is bent toward the inside of the movable expansion plate 4. The angle between the inner side of the bending part 10 and the inner side of the movable expansion plate 4 is greater than 135° and less than 170°. The four bending parts are fixed to the sides of the fixed base plate 1. There are several adsorption holes 11 equidistantly provided on the inner side of the part 10, and the bent part 10 adsorbs the rubber sleeve through the adsorption holes 11 to facilitate pulling the rubber sleeve and expanding its internal size, so as to facilitate the insertion of the laptop wiring harness therein. Sealing rubber strips 12 are fixedly installed on the inner sides of the four bent parts 10. The sealing rubber strips 12 can seal the gap between the bent part 10 and the rubber sleeve, so that the bent part 10 can better adsorb the rubber sleeve through the adsorption holes 11. The input end of the air pump 2 is connected to the interior of the mobile expansion board 4, and the input end of the air pump 2 is fixedly connected to a three-way valve 13. The remaining two ends of the three-way valve 13 are respectively fixedly connected to an air inlet pipe 15 and a connecting air pipe 14. The end of the connecting air pipe 14 is fixedly connected to an air extraction hose 3, and the two ends of the air extraction hose 3 are respectively fixedly connected to the lower surfaces of the two mobile expansion boards 4.

[0022] When the present invention is in use, the rubber sleeve is placed between the two movable expansion plates 4, and the two cylinders 8 drive the two movable expansion plates 4 to move in opposite directions, so that the movable expansion plates 4 and the curved portion 10 are in contact with the outer surface of the rubber sleeve. Then the air pump 2 works to extract the air inside the movable expansion plate 4, and the rubber sleeve is adsorbed on the curved portion 10 through the adsorption hole 11. The two cylinders 8 drive the two movable expansion plates 4 to move in opposite directions, so that the rubber sleeve can be expanded to increase the internal size of the rubber sleeve. Then the notebook wiring harness is inserted into the rubber sleeve, and the two cylinders 8 drive the two movable expansion plates 4 to move in opposite directions. Then the three-way valve 13 is adjusted to make the air inlet pipe 15 and the interior of the movable expansion plate 4 connected, so that outside air enters the interior of the movable expansion plate 4, and the adsorption of the adsorption hole 11 on the rubber sleeve is removed, and the rubber sleeve is sleeved on the outer surface of the wiring harness.
