Description

Technical Field

[0001] The invention relates to the technical field of heat shrink processing devices, and in particular to a heat shrink machine for round ring terminals. Background Art

[0002] Heat shrink tubing is a special polyolefin heat shrink tubing. The outer layer is made of high-quality soft cross-linked polyolefin material and the inner layer is made of hot melt adhesive. The outer layer material has the characteristics of insulation, corrosion resistance, and wear resistance. The inner layer has the advantages of low melting point, waterproof sealing and high adhesion. It is mainly used for insulation, sealing and protection of cables. Simply put, heat shrink tubing is used on live equipment, which has the functions of sealing, waterproofing and electrical insulation. During the use of heat shrink tubing, it is generally necessary to heat it to shrink it so that it can fit the wire and play a role of fixing and protection. The shrinking method of existing products is to manually place the heat shrink tubing on the wire at the muzzle of the hot air gun, and shrink the heat shrink tubing by hot air. Because the heat shrink tubing is close to the terminal of the wire, it is easy to be blown by the hot air when the heat shrink tubing is manually taken, causing burns. At the same time, the working efficiency of this method is also very low. The fatigue of manual work after a long time will greatly reduce the processing efficiency. Summary of the invention

[0003] The technical problem to be solved by the present invention is: to overcome the shortcomings of the prior art and provide a heat shrink machine for ring terminals, thereby avoiding poor heat shrinkage caused by different manual techniques due to replacement of employees; not only the shrinkage position remains consistent, but the temperature is constant and controllable; the heat shrinkage efficiency is improved, and the efficiency is increased by more than several times.

[0006] The temperature control device includes a heater, a radiator, a temperature controller and a temperature sensor; the temperature sensor is installed on the heat shrink device, and the temperature sensor transmits the collected temperature to the temperature controller. The temperature controller controls the heating temperature change of the heater and drives the radiator to keep the temperature of the heat shrink device relatively constant;

[0007] The heat shrink device comprises a driving motor, an assembly line, and a heat shrink unit installed on the assembly line. The heat shrink unit moves cyclically along the assembly line under the drive of the driving motor. The heat shrink unit comprises a base, a roller arranged below the base, and a heat shrink plate arranged above the base. The heat shrink plate comprises a fixed plate in contact with the base, and an inclined plate extending outward from the base.

The mounting column is fixed to the terminal head of the circular ring terminal, the limiting column is fixed to the pipe part of the circular ring terminal, and the circular ring terminal is arranged close to the heat shrink plate.

[0008] Preferably, the rollers of the heat shrink unit form part of an assembly line, and the rollers of adjacent heat shrink units are connected in sequence.

[0009] Preferably, the annular terminal comprises an annular terminal head, an elongated tubular portion, and a heat shrinkable tube connecting the terminal head and the tubular portion.

[0010] Preferably, a groove is processed in the middle of the inclined plate, and the groove matches the heat shrink tube of the ring terminal.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figure 1 As shown, a heat shrink machine for a ring terminal includes a housing, a temperature control device 2 installed above the housing, and a heat shrink device installed below the temperature control device 2, wherein:

[0027] The temperature control device 2 includes a heater, a radiator, a temperature controller and a temperature sensor; the temperature sensor is installed on the heat shrink device, and the temperature sensor transmits the collected temperature to the temperature controller, and the temperature controller controls the heating temperature change of the heater and drives the radiator to keep the temperature of the heat shrink device relatively constant;

[0028] The heat shrink device includes a driving motor, an assembly line, and a heat shrink unit 1 installed on the assembly line. The heat shrink unit 1 moves cyclically along the assembly line under the drive of the driving motor. The heat shrink unit 1 includes a base 14, a roller 15 arranged below the base 14, and a heat shrink plate 13 arranged above the base 14. The heat shrink plate 13 includes a fixed plate in contact with the base 14, and an inclined plate extending outward from the base 14. A limiting column 12 is arranged at the front end of the fixed plate, and a mounting column 11 is arranged at the end of the inclined plate. The mounting column 11 is fixed to the terminal head 31 of the circular terminal 3, the limiting column 12 is fixed to the pipe part 33 of the circular terminal 3, and the circular terminal 3 is arranged close to the heat shrink plate 13.

[0029] Working principle:

[0030] First, the annular terminal 3 is placed on the heat shrink unit 1 in sequence. That is, the terminal head 31 and the tube part 33 of the annular terminal 3 have been welded, and the heat shrink tube 32 is sleeved and directly placed on the heat shrink unit 1. Since the inclined plate is inclined, the heat shrink tube 32 slides down along the groove 16 to the bottom of the groove 16, that is, the heat shrink tube 32 slides down to the terminal head 31 by gravity.

[0031] Secondly, start the temperature control device 2 and the assembly line. The temperature control device 2 heats the heat shrink tube 32 on the heat shrink plate 13 through the heater. During the heating process, temperature feedback is performed through the temperature sensor, and the temperature is adjusted by controlling the heater power. If necessary, the radiator is turned on to cool the heat shrink device under the casing, so as to keep the temperature inside the heat shrink device constant. While the temperature control device 2 provides a constant temperature, the annular terminal 3 is driven by the assembly line to be baked in turn through the heater. The baking part is the heat shrink tube 32 at the groove 16 of the inclined plate. The heat shrink tube 32 is shrunk by baking, so as to ensure that the contracted positions of the terminal head 31 and the pipe part 33 remain consistent and the degree of heat shrinkage meets the process requirements.

[0032] Example 2

[0033] On the basis of Example 1, Figures 2 to 5 As shown, the rollers 15 of the heat shrink unit 1 form a part of the production line, and the rollers 15 of adjacent heat shrink units 1 are connected in sequence.

[0034] Preferably, the annular terminal 3 includes an annular terminal head 31 , an elongated tubular portion 33 , and a heat shrink tube 32 connecting the terminal head 31 and the tubular portion 33 .

[0035] Preferably, a groove 16 is processed in the middle of the inclined plate, and the groove 16 matches with the heat shrink tube 32 of the ring terminal 3 .

[0036] Preferably, the heat shrink plate 13 is made of a metal sheet, the inclined plate is arranged downwardly relative to the fixed plate, and the heat shrink tube 32 slides down from the groove 16 to the bottom. The cut heat shrink tubes 32 are placed on the groove 16 in sequence, and the width of the groove 16 is greater than the diameter of the heat shrink tube 32, so the heat shrink tube 32 is sleeved on the pipe part 33 and can slide downward along the inclined plate.

[0037] Preferably, the limiting column 12 is composed of two left and right columns, and the width of the gap between the columns meets the limiting requirement of the pipe part 33.

Without departing from the spirit and essence of the present invention, a person of ordinary skill in the art may make various equivalent modifications or substitutions to the embodiments of the present invention, and these modifications or substitutions shall be within the scope of the present invention. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, and all of these shall be within the scope of protection of the present invention.
