DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 are within the scope of protection of the present invention.

[0024] In one embodiment, see Figure 1-Figure 9 , a light bulb tester, comprising a mounting base plate 1, a conveying mechanism 3 and a testing mechanism 4; The conveying mechanism 3 includes a conveying bracket 6 arranged at both ends of the mounting base plate 1. The conveying bracket 6 is arranged at the left and right ends of the upper surface of the mounting base plate 1 in a front-to-back direction. The conveying bracket 6 is a U-shaped structure with an opening upward. A conveying shaft 7 arranged in a front-to-back direction is rotatably connected at the upper end of the conveying bracket 6. Conveying wheels 8 are arranged on both the front and rear sides of the conveying shaft 7. The conveying wheels 8 on the left and right sides are respectively connected to the left and right sides of the conveying belt 10 of the annular structure, so that the conveying wheels 8 can drive the conveying belt 10 to rotate when rotating. A driving motor is arranged inside the conveying shaft 7 to control the conveying shaft 7 to rotate, and the outer side of the conveying belt 10 A placement horizontal plate 9 is provided which is arranged in a front-to-back direction, and a material discharge groove 11 is provided in the middle of the placement horizontal plate 9. The spherical part of the bulb 5 can be placed in the material discharge groove 11. The bulb 5 includes a spherical structure for emitting light and a columnar structure for connecting electricity. A zero line thread sleeve 16 is provided on the side of the columnar part of the bulb 5. The zero line thread sleeve 16 can be threadedly connected and fixed on the bulb 5 fixing seat, and the zero line thread sleeve 16 will be connected to the zero line of the bulb 5 fixing seat. A live line contact protrusion 17 is provided at the end of the columnar part of the bulb 5, and the live line contact protrusion 17 will be connected to the live line of the bulb 5 fixing seat, so as to realize a conductive circuit for emitting light; The detection mechanism 4 includes a side bracket 15 arranged in the middle of the side edge of the mounting base plate 1. The side bracket 15 is L-shaped and arranged in a front-to-back direction. The vertical rod of the side bracket 15 is fixedly connected to the middle of the rear side of the upper surface of the mounting base plate 1. The horizontal rod of the side bracket 15 extends forward. A horizontal conductive spring 19 is arranged at the front end of the horizontal rod of the side bracket 15. The right end of the conductive spring 19 is inclined forward. Therefore, when the light bulb 5 moves from left to right, the zero-line threaded sleeve 16 on the side of the light bulb 5 will contact the front side of the conductive spring 19 to achieve the effect of circuit conduction, and a placement rack 20 arranged in a front-to-back direction is arranged on the front side of the upper side of the horizontal rod of the side bracket 15. The placement rack 20 is L-shaped, and the vertical rod of the placement rack 20 is fixed to the side bracket. 15, the horizontal rod of the placement rack 20 is arranged in a front-to-back direction, and guide slide bars 23 are vertically arranged on the front and back sides of the lower surface of the horizontal rod of the placement rack 20, the middle part of the guide slide bar 23 is slidably connected with a slider 22, and the sides of the front and rear sliders 22 are rotatably connected to the front and rear ends of the conductive roller 24 arranged in the front and rear directions, and an anti-slip plate 21 is arranged at the lower end of the conductive slide bar 32, the anti-slip plate 21 will prevent the slider 22 from being disengaged from the guide slide bar 23, and the conductive roller 24 can have a conductive effect. Therefore, when the light bulb 5 moves from left to right, the live wire contact protrusion 17 above the light bulb 5 will contact the conductive roller 24, and the conductive roller 24 will be pushed upward and rotate adaptively, thereby achieving the effect of conduction between the live wire contact protrusion 17 and the conductive roller 24.

[0025] In one case of the present embodiment, a protective sleeve 25 is vertically arranged in the middle of the horizontal rod of the placement rack 20, and the bottom of the protective sleeve 25 is a hollow structure. A clearance groove 30 is arranged at the lower end of the side walls on the left and right sides of the protective sleeve 25. Therefore, when the conductive roller 24 moves upward, it will move to the inside of the clearance groove 30. At this time, the middle part of the upper end of the conductive roller 24 will move to the inside of the hollow structure below the protective sleeve 25. A vertically arranged conductive sliding rod 32 is slidably connected to the middle part of the protective sleeve 25. A contact plate 31 is arranged at the lower end of the conductive sliding rod 32. The conductive sliding rod 32 will be connected to the external live wire. When the conductive roller 24 moves upward, it will contact the contact plate 31. At this time, the conductive roller 24 will be in contact with the external live wire. In order to ensure that the conductive roller 24 is always in contact with the contact plate 31 after rising, the conductive slide bar 32 is designed to be in sliding connection with the protective sleeve 25, thereby ensuring that the conductive roller 24 will maintain contact for a period of time after rising, and because the protective sleeve 25 is provided, the conductive roller 24 will be disengaged from the contact plate 31 when it falls. At this time, the contact plate 31 is located inside the hollow structure below the protective sleeve 25. At this time, the operator will not touch the contact plate 31, thereby achieving a certain protection effect and avoiding the operator's electric shock problem. At the same time, in order to limit the maximum descending distance of the conductive slide bar 32, a limit plate 33 is provided at the upper end of the conductive slide bar 32 to prevent the conductive slide bar 32 from being disengaged from the protective sleeve 25.

[0026] In one case of the present embodiment, a fixing block 18 is provided on the left side of the front end of the horizontal rod of the side bracket 15, and the front end of the fixing block 18 is connected to the left end of a conductive spring clip 19. The conductive spring clip 19 adopts an elastic conductive material, and the fixing block 18 is connected to the neutral line of the external circuit. Therefore, when the light bulb 5 moves from left to right, the neutral line threaded sleeve 16 of the light bulb 5 will be in contact with the front side of the conductive spring clip 19, and the conductive spring clip 19 will be slightly bent backwards, so that the neutral line threaded sleeve 16 of the light bulb 5 is connected to the conductive spring clip 19, that is, the neutral line threaded sleeve 16 of the light bulb 5 is connected to the external neutral line.

[0027] In one case of the present embodiment, the discharge trough 11 is a hollow structure, and the inner wall of the discharge trough 11 is an arc surface, so when the spherical light-emitting structure below the bulb 5 will effectively fit with the discharge trough 11, it can also play a certain centering effect, and a part of the spherical light-emitting structure below the bulb 5 will pass through the discharge trough 11 and leak under the horizontal plate 9, so a light intensity detection component 14 is set in the middle of the installation base plate 1. At this time, the light intensity detection component 14 can detect the luminous intensity of the exposed part of the spherical light-emitting structure of the bulb 5, that is, detect whether the bulb 5 is normally lit, and after the bulb 5 moves to the top of the light intensity detection component 14, the neutral line threaded sleeve 16 above the bulb 5 will contact the conductive spring 19, and the live line contact protrusion 17 will push the conductive roller 24 upward, and the circuit of the power supply of the bulb 5 and the detector is connected, and the bulb 5 can emit light normally. The light intensity detection component 14 includes a bracket 26 arranged in the middle of the installation base plate 1. The bracket 26 is a U-shaped structure with an opening downward. A black box 27 is arranged in the middle of the upper end of the bracket 26. A cavity 28 opened at the top is arranged in the middle of the upper part of the black box 27. A light sensor 29 is arranged inside the cavity 28. By arranging the light sensor 29 in the cavity 28 inside the black box 27, the influence of light from the external environment on the light sensor 29 is avoided. Therefore, when the light bulb 5 above emits light, the light generated can irradiate the inside of the cavity 28, so that the light sensor 29 can timely identify the brightness of the light bulb 5.

[0028] In one case of the present embodiment, vertical poles 12 are vertically arranged on the front and rear sides of the discharge trough 11, and the upper ends of the vertical poles 12 are fixedly connected to the two ends of the elastic rope 13 arranged in the left and right directions. When the light bulb 5 is placed into the discharge trough 11 from top to bottom, the spherical light-emitting part of the light bulb 5 will be squeezed under the elastic rope 13, so that the light bulb 5 is restricted by the elastic rope 13, so that the spherical light-emitting part of the light bulb 5 is tightly pressed in the discharge trough 11, so that the light bulb 5 will not shake during the movement of the placement horizontal plate 9, thereby improving the stability of the light bulb 5.

[0029] In one case of the present embodiment, the two sides of the mounting base plate 1 are provided with feeding manipulators 2 for placing the bulb 5 in the discharging trough 11 or taking the bulb 5 out of the discharging trough 11. The feeding manipulators 2 are conventional grasping manipulators. The feeding manipulators 2 arranged on the left side of the mounting base plate 1 can grab the bulb 5 from the production line and place the bulb 5 with the spherical light-emitting part facing downward into the discharging trough 11. The feeding manipulators 2 on the right side of the mounting base plate 1 can take the bulb 5 out of the discharging trough 11. If the bulb 5 is normal, the feeding manipulators 2 on the right side will place the bulb 5 again in the subsequent production line. If the bulb 5 does not emit light normally, the feeding manipulators 2 on the right side will place the problematic bulb 5 into the relevant problem transfer box, waiting for subsequent processing by the operator.

[0030] During the implementation of this embodiment, the installation base plate 1 is installed at the end of the bulb 5 processing line, that is, it is installed on the line after the bulb 5 is assembled. At this time, the feeding robot 2 on the left can transfer the assembled bulb 5 to the discharge trough 11 for inspection and processing, and the relevant subsequent inspection line is installed on the rear side of the installation base plate 1. At the same time, a transfer box for problem bulbs 5 is also placed to store some bulbs 5 that cannot light up normally.

[0031] Start the driving motor inside the conveying shaft 7, so that the placement cross plate 9 rotates clockwise with the conveying belt 10, and the feeding robot 2 on the left will place the light bulb 5 in the discharging trough 11. At this time, the light bulb 5 moves from left to right along with the placement cross plate 9. When the light bulb 5 moves to the middle of the installation base plate 1, the neutral line thread sleeve 16 of the light bulb 5 will squeeze the conductive spring piece 19 backward, and the live line contact protrusion 17 of the light bulb 5 will push the conductive roller 24 upward. At this time, the light bulb 5 is connected to the power supply circuit of the detector, and the light bulb 5 moves to the top of the light sensor 29. If the light bulb 5 There are no problems with the installation. At this time, the bulb 5 lights up normally, and the light sensor 29 detects the normal light intensity. The bulb 5 will move to the right along with the horizontal plate 9, and the picking and feeding robot 2 on the right will transfer the bulb 5 to the subsequent processing line. If the bulb 5 does not light up normally, the light sensor 29 does not detect the normal light intensity at this time, and it is therefore determined to be a problem bulb 5. After the bulb 5 continues to move to the right, the picking and feeding robot 2 on the right will take out the problem bulb 5 and put the problem bulb 5 into the problem bulb 5 transfer box, completing the entire bulb 5 detection process.

[0032] The present invention is applicable to a light bulb tester. By setting a conductive roller 24 that moves up and down and cooperating with a conductive spring sheet 19, the light bulb 5 can complete the power-on detection process when it moves from left to right, thereby improving the detection efficiency. Moreover, when the conductive roller 24 is not in contact with the light bulb 5, it will move downward to cut off the power, thereby avoiding the problem of electric shock to the operator and improving the safety of the tester.

[0033] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
