Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of carbon crystal testing equipment, and particularly relates to a carbon crystal thrust tester. BACKGROUND

[0002] Carbon crystal is also called carbon brush or carbon fine, which is a medium for connecting the stator and rotor of a direct current motor through a collector ring, and has the characteristics of small resistance, high conductivity and wear resistance. The carbon crystal is usually fixed in the cover body by the cover body of the carbon crystal, and a fixing groove is arranged in the cover body to fix the carbon crystal. Since maintaining the high-speed rotation of the direct current motor requires not only stable power supply but also stable conductive medium (i.e. carbon crystal) at the connection contact between the stator and rotor of the direct current motor, it is necessary to test the carbon crystal in the cover body to test whether it is stable and how much force is needed to make the carbon crystal separate from the cover body. The current carbon crystal thrust test is usually carried out manually by using tools to push the carbon crystal, which not only consumes manpower but also has unstable factors. After long-time manual testing of the carbon crystal, the worker's physical strength, energy and patience are greatly tested, which may lead to defective carbon crystals that are not detected, thereby affecting the product yield and causing unnecessary losses.

The pressing module is further provided with a dotting device 6. The operation table 1 is further provided with an unlocking switch 11, a start button 12, and an emergency stop button 13.

[0027] As Figure 6 shown is a schematic diagram of a carbon crystal to be tested and its rubber cover, including a rubber cover A, a fixed groove B, and a carbon crystal C.

[0028] It is worth mentioning that the import photoelectric door 98 and the export photoelectric door 99 are respectively arranged at the left end and the right end of the horizontal SMC cylinder 2, and the detection height of the import photoelectric door 98 and the export photoelectric door 99 is slightly higher than the height of the jig seat 23, the carbon crystal C and the glue cover A placed on the jig seat 23, that is, the detection height of the photoelectric door is between the height of the jig seat 23 and the height of the carbon crystal and the glue cover placed on the jig seat. Respectively used for detecting whether there is a carbon crystal C on the jig seat 23 when testing the thrust of the carbon crystal. When used for carbon crystal thrust test, after placing the carbon crystal C and the glue cover A on the jig seat 23 on the cylinder sliding table 21, the import photoelectric door 98 detects the carbon crystal C and the glue cover A, and sends a signal to the SMC cylinder 2 to make it transport the cylinder sliding table 21 to the pressing die assembly directly below to be detected. After the detection is completed, the SMC cylinder 2 transports the cylinder sliding table 21 to the export photoelectric door 99, and when the export photoelectric door 99 detects that the tested carbon crystal C has been taken out, it sends a signal to the SMC cylinder 2 to make the SMC cylinder 2 transport the cylinder sliding table 21 to the rightmost position for the next carbon crystal detection.

[0029] In the embodiment, the push pin module includes a push pin shell 31, a module mounting bracket 32, a module mounting plate 33 arranged on the module mounting bracket 32, a push pin cylinder 34 arranged at one end of the module mounting plate 33, a pressure sensor 35 arranged on the module mounting plate 33 away from the one end of the push pin cylinder 34 and connected with the push pin cylinder 34, and a push pin 36 connected with the other end of the pressure sensor 35. The movement direction of the two groups of push pins is perpendicular to the SMC cylinder 2, and the connection line of the two groups of push pins is perpendicular to the cylinder body of the SMC cylinder 2. In use, the push pin 36 is used to push the carbon crystal C to slide in the fixed groove B in the glue cover A, test the stability of the carbon crystal C in the glue cover A, and obtain the thrust of the push pin module pushing the carbon crystal through the pressure sensor 35. The stability of the carbon crystal C is reflected by the obtained thrust, and whether the carbon crystal C in the glue cover A is qualified is judged according to the thrust.

[0030] It is worth mentioning that the push pin module is two groups, respectively arranged at the two sides of the SMC cylinder 2. In use, the two groups of push pins are used to push the carbon crystal C to test the stability of the carbon crystal, and the thrust received by the carbon crystal is obtained through the pressure sensor 35 connected with the push pin 36.

[0031] In the embodiment, the pressing module includes a pressing cylinder 41, a cylinder auxiliary support 42, a cylinder pressing plate 43, and a product pressing device. The cylinder pressing plate 43 is in power connection with the pressing cylinder 41, and the cylinder pressing plate 43 is provided with a support hole. The cylinder auxiliary support 42 passes through the support hole, so that the cylinder pressing plate 43 can slide up and down on the cylinder auxiliary support 42. The cylinder auxiliary support 42 is further provided with a limiting plate 421 to prevent the cylinder pressing plate 43 from being separated from the cylinder auxiliary support 42 when sliding upward on the cylinder auxiliary support 42. When the carbon crystal thrust is tested, the carbon crystal to be tested is placed on the jig seat 23, and the pressing cylinder 43 is controlled to move downward to press the product pressing device against the carbon crystal, so as to facilitate the thrust test of the pushing needle module. It is worth noting that the product pressing device includes a cylindrical shell 441, a movable bolt 442, and a spring 443. When pressing, the movable bolt 442 is pressed on the rubber cap of the carbon crystal to be tested, and the spring 443 plays a buffering role.

[0032] In the embodiment, the dotting device 6 includes a dotting needle 61, a dotting cylinder 62, and a dotting needle mounting plate 63. The dotting cylinder 62 is installed on one side of the product pressing device, the dotting needle 61 is in power connection with the dotting cylinder 62, and the dotting needle 61 is fixedly installed on the dotting needle mounting plate 63. After the detection is completed, when the thrust obtained by the pressure sensor 35 meets the set value, the dotting device 6 can be selected to mark the rubber cap A loaded with the carbon crystal C.

[0033] In the embodiment, the fork separating mechanism 5 includes a fork separating cylinder 51, a fork guiding assembly 52, and a carbon crystal fork 53 in power connection with the fork separating cylinder 1. The fork separating cylinder 51 is arranged directly below the jig seat 23, the carbon crystal fork 53 penetrates through the hole in the jig seat mounting plate 22, and the top end of the carbon crystal fork 53 is in the shape of an arrowhead with a small top and a large bottom. The fork guiding assembly 52 is installed on both sides of the support rod of the carbon crystal fork 53 below the jig seat mounting plate 22. When the carbon crystal thrust is tested, after the thrust test of the pushing needle module is completed, the fork separating cylinder 51 is controlled to move upward to lift the carbon crystal fork 53 upward, so that the carbon crystal fork 53 extrudes the carbon crystal and returns the carbon crystal to the original position.

[0034] In the embodiment, a metal shell 14 is further arranged on the operation table 1, which can cover the SMC cylinder 2, the pushing needle module, the pressing module, the import photoelectric door 98, and the export photoelectric door 99. The shell 14 is provided with a warning light 15, a face recognition device 16, and a display 17. The bottom of the operation table 1 is provided with a rubber pad 18, and the operation table 1 is provided with an operation keyboard 19 below. The display 17 and the pressure sensor 35 are in electrical signal connection, and are used to display the pressure signal obtained by the pressure sensor 35. The face recognition device 16 is used to identify the staff using the carbon crystal thrust tester.

[0035] In use of the carbon crystal thrust tester, the initial position of the electric cylinder sliding table 21 is at the detection position of the inlet photoelectric door 98. After the carbon crystal C and its glue cover A to be detected are placed on the electric cylinder sliding table 21, the inlet photoelectric door 98 detects the carbon crystal and sends a signal to the SMC electric cylinder 2, so that the SMC electric cylinder 2 transports the electric cylinder sliding table 21 to be detected directly below the pressing die assembly. When the electric cylinder sliding table 21 is directly below the pressing die assembly, the pressing die assembly moves downward to press the movable pin 442 on the product pressing device on the glue cover A of the carbon crystal, so that the glue cover cannot be displaced on the jig seat 23 under the thrust of the push pin assembly. After the glue cover A is pressed, the two groups of push pin assemblies perform thrust test on the carbon crystal C in the glue cover A. Specifically, the push pin cylinders 34 of the front and rear two groups of push pin assemblies respectively push the push pins 36 to point to the carbon crystal C in the glue cover A between the two groups of push pins. The carbon crystal C will be displaced in the fixed groove B under the thrust of the push pin 36. At this time, the pressure signal obtained by the pressure sensor 35 can reflect the thrust size of the push pin cylinder 34. Further, according to the thrust size, it can be judged whether the stability of the carbon crystal C in the glue cover A is qualified. After the thrust test of the carbon crystal C is completed, the two groups of push pin assemblies return to the original position, and the yoke separation cylinder 51 of the yoke separation mechanism 5 is controlled to separate the yoke 53 upward, so that the yoke 53 extrudes the carbon crystal C and pushes the carbon crystal C back to the original position. After the detection is completed, the dotting device 6 can be selected to dot the glue cover A loaded with the carbon crystal C. Finally, the pressing die assembly is lifted to a height, the glue cover A loaded with the carbon crystal C on the jig seat 23 is released, the SMC electric cylinder 2 transports the electric cylinder sliding table 21 to the rightmost end of the SMC electric cylinder 2. At this time, the tested carbon crystal C and its glue cover A are taken out. After the outlet photoelectric door 99 detects that the tested carbon crystal C and its glue cover A have been taken out, a signal is sent to the SMC electric cylinder 2, so that the SMC electric cylinder 2 transports the electric cylinder sliding table 21 to the leftmost end for the next carbon crystal detection.

[0036] The above merely provides the preferred embodiments of the present application, but should not be used to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
