Description

Technical Field

[0001] The utility model relates to the technical field of automatic detection devices for wire stripping machines, in particular to a wire stripping photosensitive switch. Background Art

[0002] A wire stripping machine is a machine that strips the plastic sheath and metal core of wires. It is the most widely used machine in the machinery industry, and there are many types of machines to match it according to the wire sheath strength, wire diameter, material and composition of the wire.

[0003] Generally speaking, according to the wire sheath strength of the wire (that is, the difficulty of stripping the wire sheath, the more difficult it is, the greater the stripping force, and the easier it is, the less the stripping force), the gap and pressure between the wire inlet and outlet wheels need to be adjusted. The entire adjustment process requires the operator to conduct multiple tests, and each test requires the machine to be stopped to check the sample. It is difficult to achieve the technical effect of real-time detection and real-time feedback, which seriously slows down the production progress.

[0004] The applicant proposed the present invention based on the principles of better guiding production and reducing unnecessary waste. Utility Model Content

[0005] To this end, the utility model provides a wire stripping photosensitive switch to solve the problem that the wire stripping machine in the prior art cannot perform online adjustment on the gap and pressure between the wire inlet wheel and the wire outlet wheel.

[0006] The utility model discloses a wire stripping photosensitive switch, comprising:

[0007] The bottom of the vertical pole is inserted into the base, and the top is horizontally provided with a mounting bracket, which is composed of two parallelly arranged carriers;

[0008] A reflector is provided directly below the photoelectric transceiver;

[0009] The photoelectric transceiver and the reflector are both arranged in the mounting bracket and respectively mounted on the two carriers. When the wire harness passes between the photoelectric transceiver and the reflector, the actual stripping effect of the wire harness is detected.

[0010] Furthermore, the upright pole comprises:

[0011] A telescopic rod, the tail of which is fixedly provided with a prismatic plug, the prismatic plug being suitable for being inserted into the base and cooperating with a prismatic hole vertically provided on the base;

[0012] The mounting plane is arranged at the head end of the telescopic rod, and the mounting bracket is arranged on the mounting plane.

[0013] Furthermore, the carrier includes:

[0014] Sheet metal parts, with arc notches at the tail and loading positions at the head;

[0015] A swivel hole is arranged at the center of the arc notch, and the swivel hole is rotatably arranged on the mounting plane by a pin shaft;

[0016] Wherein, a fastener is arranged in the arc groove, and the tail of the sheet metal part is fixed on the installation plane by tightening the fastener.

[0017] Furthermore, anchor holes are provided on the carrier, and the anchor holes on the two carriers are aligned.

[0018] Furthermore, a laser light source and a photosensitive element are provided in the optoelectronic transceiver, the laser light source and the photosensitive element are installed at the same position, and the laser light source is forwardly aligned with the reflective plate.

[0019] Furthermore, the reflector is mounted on a mirror base;

[0020] The mirror base comprises:

[0021] A pair of guide plates are symmetrically arranged on both sides of the base body, the guide plates and the base body are perpendicular to each other, and a reflector is placed flat on the base body;

[0022] The guide holes are arranged on the guide plates, and the guide holes on a pair of guide plates are aligned and suitable for passing the wire harness.

[0023] The utility model has the following advantages:

[0024] The wire stripping photosensitive switch disclosed in the technical solution utilizes a reflector to reflect light signals, and utilizes a photoelectric transceiver to synchronously output and receive light. When the wire stripping cable passes between the reflector and the photoelectric transceiver, the cable itself will hinder the amount of light received by the photoelectric transceiver. When the wire stripping fails, the electrical signal emitted by the photoelectric transceiver can interrupt the wire stripping machine or instruct the operator that the gap and pressure between the wire input wheel and the wire output wheel are not adjusted properly, thereby enabling online guidance of production, thereby achieving the technical effect of real-time detection and real-time feedback.

DETAILED DESCRIPTION

[0035] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part 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 are within the scope of protection of the present invention.

[0036] Please refer to Figure 1-Figure 7 The utility model discloses a wire stripping photosensitive switch, which has multiple uses. It can be connected to a PLC to output a switch quantity to a controller, and can also be connected to a device to interrupt the device or prompt an operator to supervise the production quality.

[0037] The specific technical solution of the utility model is now described.

[0038] In a specific embodiment disclosed in the present utility model, Figure 1 The wire stripping photosensitive switch includes a pole 1, a carrier 3 and a photoelectric transceiver 5, wherein the mounting bracket is composed of two parallel mounted carriers 3, the mounting bracket is arranged at the top of the pole 1, the bottom end of the pole 1 is inserted in the base 2, and the base 2 is installed in the wire stripping machine or other related equipment by bolts. In this embodiment, the two parallel mounted carriers 3 are respectively equipped with a photoelectric transceiver 5 and a reflector 4, and the reflector 4 is arranged directly below the photoelectric transceiver 5. When a wire bundle passes between the photoelectric transceiver 5 and the reflector 4, the photoelectric transceiver 5 can detect the effect of wire bundle stripping.

[0039] In this embodiment, it should be noted that Figure 3 The photoelectric transceiver 5 is provided with a laser light source 51 and a photosensitive element 52, and the laser light source 51 and the photosensitive element 52 are installed in the same position, that is, the photoelectric transceiver 5 can release and receive light synchronously and in the same direction. Since the laser light source 51 is positively aimed at the reflector 4, the laser released by the laser light source 51 is reflected by the reflector 4 and irradiated onto the photosensitive element 52, causing the resistance value of the photoresistor to change, and the stripped wire harness blocks the propagation of light. If the wire harness stripping fails, resulting in the outer skin of the wire harness not falling off, it will inevitably lead to insufficient light entering the photosensitive element 52, thereby causing changes in physical quantities such as the resistance value or voltage of the photosensitive element 52. This change is converted into a signal that can be received by the transistor through the amplifier, and the device can be switched on and off.

[0040] In some embodiments, Figure 5 The carrier 3 includes a sheet metal part 31 and a swivel hole 32, wherein the sheet metal part 31 is a plate body with a right angle, a loading position 34 is arranged at the head end of the sheet metal part 31, and the position of the loading position 34 is used to install the reflector 4 or the photosensitive element 52, and an arc groove 33 is arranged at the tail of the sheet metal part 31, and a swivel hole 32 is arranged at the center of the arc groove 33, and the swivel hole 32 is arranged on the installation plane 13 of the vertical pole 1 through a pin shaft rotation, thereby allowing the sheet metal part 31 to rotate around the swivel hole 32, and at the same time, a fastener 7 is arranged in the arc groove 33. When the sheet metal part 31 needs to be fixed, the fastener 7 can be tightened to generate a pre-tightening force to fix the tail of the sheet metal part 31 on the installation plane 13.

[0041] In this embodiment, if Figure 4The two sheet metal parts 31 are used to install the photoelectric transceiver 5 and the reflector 4. Since the photoelectric transceiver 5 and the reflector 4 need to be accurately aligned to reduce the test error, anchor holes 6 are set on the two sheet metal parts 31 of the carrier 3. When in use, it is possible to directly visually observe whether the two anchor holes 6 pass through the same beam of light, and then determine whether the two sheet metal parts 31 are parallel, thereby ensuring that the photoelectric transceiver 5 and the reflector 4 are accurately installed.

[0042] In one embodiment disclosed in the present utility model, Figure 6 , the vertical pole 1 is a rod body of fixed length connecting the base 2 and the mounting bracket. Optionally, the vertical pole 1 can also be an assembly structure, specifically including a telescopic rod 11, a prismatic plug 12 and a mounting plane 13, wherein the telescopic rod 11 is a sleeve with adjustable length, and a prismatic plug 12 is fixedly provided at the tail of the telescopic rod 11, and the prismatic plug 12 is suitable for being inserted into the base 2 and matched with the prism hole vertically provided on the base 2, thereby adjusting the rotation angle of the prismatic plug 12 and the telescopic rod 11 by rotating and plugging, and since the head end of the telescopic rod 11 is provided with a mounting plane 13, and a mounting bracket is provided on the mounting plane 13, the position and posture of the mounting bracket can be adjusted.

[0043] In some embodiments, Figure 7 , the reflector 4 is mounted on the mirror base 8, wherein the mirror base 8 includes a pair of guide plates 81 and guide holes 82. First, a pair of guide plates 81 are symmetrically arranged on both sides of the base 83, and the guide plates 81 and the base 83 are perpendicular to each other, and the reflector 4 is placed flat on the base 83, so that the guide plates 81 play a light shielding role to prevent external light from interfering with the photosensitive element. In addition, guide holes 82 are arranged on the guide plates 81, and the guide holes 82 on the pair of guide plates 81 are aligned with each other and suitable for passing the wire harness, so that the wire harness and the reflector 4 remain parallel, preventing the problem of false triggering of the photoelectric transceiver 5 due to the bending and tilting of the wire harness.

[0044] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
