Description

Technical Field

[0001] The invention relates to the field of electronic measurement technology, and in particular to a code disc installation device for a photoelectric encoder. Background Art

[0002] A photoelectric encoder is a sensor that converts the mechanical geometric displacement of the output shaft into pulses or digital quantities through photoelectric conversion. It is mainly used in various CNC equipment and is currently the most widely used sensor. The photoelectric encoder is mainly composed of a grating and a photoelectric detection device. In the servo system, the grating is coaxial with the motor so that the rotation of the motor drives the rotation of the grating, and then a number of pulse signals are output through the photoelectric detection device. The current motor speed can be calculated based on the number of pulses per second of the signal. In the process of installing the code disk of the photoelectric encoder, the base is fixed by a clamping device, and the code disk is bonded to the code disk connecting ring at the end of the spindle. After bonding, the colloid needs to be cured by irradiation with an ultraviolet lamp. Due to the extremely strong ultraviolet radiation, it is easy to cause ultraviolet damage to the human body. In summary, designing a code disk installation device that can play a protective role in the process of curing the colloid with an ultraviolet lamp has become an urgent problem to be solved.

DETAILED DESCRIPTION

[0014] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and the best embodiments.

[0015] As shown in the figure, the present invention includes a workbench 12, a first protective plate 17 arranged above the workbench 12, a second protective plate 7, a first ultraviolet lamp 10, a second ultraviolet lamp 9, a clamping device 2 and a trigger mechanism. The clamping device 2 is used to clamp and fix the photoelectric encoder base 8 so as to facilitate the bonding of the code disk onto the base 8. The first protective plate 17 and the second protective plate 7 are vertically arranged to effectively block direct ultraviolet radiation and primary reflection. The first protective plate 17 is slidably connected to the workbench 12 through a first slide rail 13. The first ultraviolet lamp 10 is arranged toward the clamping device 2 and perpendicular to the second protective plate 7. The trigger mechanism includes a first trigger component arranged on the front side of the first protective plate 17 and a second trigger component for fixing the second ultraviolet lamp 9. The first trigger component includes a connecting block 14 fixedly connected to the outer side of the first protective plate 17, a contact rod 15 arranged at one end of the connecting block 14, and a first touch switch 16 arranged relative to the contact rod 15. The second trigger component includes a carrier 6, a connecting plate 11 , a slider 19, a second touch switch 18, a driving device and a mounting bracket, a slide groove 5 is opened on the upper surface of the carrier 6, a slider 19 is slidably connected in the slide groove 5, a second touch switch 18 is provided in the slide groove 5 near one end of the clamping device 2, the slider 19 is connected to the driving device, the upper surface of the slider 19 is fixedly connected to the connecting plate 11, and a mounting bracket for installing the second ultraviolet lamp 9 is provided above the connecting plate 11. In this example, the mounting bracket includes a vertical plate 4 fixedly connected to the connecting plate 11, a connecting rod 3 arranged on one side of the vertical plate 4, and a mounting clamp arranged at the end of the connecting rod 3, the mounting clamp is used to fix the second ultraviolet lamp 9, the first touch switch 16 is electrically connected to the driving device, the second touch switch 18 is electrically connected to the first ultraviolet lamp 10 and the second ultraviolet lamp 9, when the slider 19 abuts against the second touch switch 18, the second ultraviolet lamp 9 moves to the top of the clamping device 2, and simultaneously triggers the first ultraviolet lamp 10 and the second ultraviolet lamp 9 electrically connected thereto, so as to cure and dry the colloid at the connecting position of the code disk and the base 8. After the code disc is bonded to the code disc connecting ring at the end of the spindle, the first protective plate 17 is slid to the front side of the clamping device 2, and the contact rod 15 abuts against the contact point of the first touch switch 16 to start the driving device to move the slider 19 in the slide groove 5. When the slider 19 abuts against the second touch switch 18, the second ultraviolet lamp 9 moves to the top of the clamping device 2 and simultaneously triggers the first ultraviolet lamp 10 and the second ultraviolet lamp 9 electrically connected thereto to cure and dry the colloid at the connection position between the code disc and the base 8. This setting ensures that when the protective plate moves to a position where it can block ultraviolet rays, each ultraviolet lamp switch is triggered to avoid ultraviolet damage to the operator and ensure safety.

[0016] According to the above embodiment, preferably, the second protective plate 7 is slidably connected to the workbench 12 through the second slide rail 1. During the clamping of the base 8 and the installation of the code disc, the second protective plate 7 can be moved to a position away from the clamping device 2 to avoid affecting the operation of the staff.

[0017] According to the above embodiment, preferably, the driving device includes a motor 22, a driving screw 20 and a guide rod 21, and the driving screw 20 and the guide rod 21 are symmetrically arranged on both sides of the second touch switch 18 in the slide 5, the driving screw 20 is rotatably connected in the slide 5, one end of the driving screw 20 is connected to the motor 22, the slider 19 is threadedly connected to the driving screw 20, the guide rod 21 penetrates the slider 19, and the first touch switch 16 is electrically connected to the motor 22. After the second touch switch 18 is triggered, the motor 22 stops, the first ultraviolet lamp 10 and the second ultraviolet lamp 9 irradiate the colloid connected to the code disk and the base 8 to accelerate the curing and drying speed of the colloid, and the first ultraviolet lamp 10 and the second ultraviolet lamp 9 are turned off after irradiation for a certain period of time, and the motor 22 is switched to reverse to restore the components of the second trigger assembly to the initial state. When the first protective plate 17 slides to the front side of the clamping device 2, the contact rod 15 abuts against the contact of the first touch switch 16 to start the motor 22 to rotate, so that the slider 19 threadedly connected thereto moves along the guide rod 21 to the position of the second touch switch 18. At this time, the second ultraviolet lamp 9 is above the clamping device 2, and at the same time triggers the first ultraviolet lamp 10 and the second ultraviolet lamp 9 electrically connected thereto to cure and dry the colloid at the connection position of the code disk and the base 8.

[0018] After the code disc is bonded to the code disc connecting ring at the end of the spindle, the first protective plate 17 is slid to the front side of the clamping device 2, and the contact rod 15 abuts against the contact point of the first touch switch 16 to start the driving device to move the slider 19 in the slide groove 5. When the slider 19 abuts against the second touch switch 18, the second ultraviolet lamp 9 moves to the top of the clamping device 2 and simultaneously triggers the first ultraviolet lamp 10 and the second ultraviolet lamp 9 electrically connected thereto to cure and dry the colloid at the connection position between the code disc and the base 8. This setting ensures that when the protective plate moves to a position where it can block ultraviolet rays, each ultraviolet lamp switch is triggered to avoid ultraviolet damage to the operator and ensure safety.

[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
