[0026] The annular support frame 103 is also fixedly mounted with an annular scraper 125, which is used to clean the surface of the right-angled sector plate 132. The annular support frame 103 is also provided with a driving unit, which is used to adjust the position of the right-angled sector plate 132 and the L-shaped slide plate 134. The driving unit includes four strip rotating plates 136 and four strip rotating plates 139 which are rotatably mounted on the annular support frame 103 in a circular array. The strip rotating plates 136 and the strip rotating plates 139 are arranged at intervals.

A transmission short rod 138 is fixedly arranged on the L-shaped slide plate 134, and the strip rotating plate 139 is movably connected to the corresponding transmission short rod 138.

[0027] A driven gear 137 is rotatably mounted on the bar rotating plate 136, a torsion spring is arranged between the bar rotating plate 136 and the driven gear 137, one end of the torsion spring is fixedly connected to the bar rotating plate 136, and the other end of the torsion spring is fixedly connected to the driven gear 137, a driven gear 2 140 is fixedly mounted on the bar rotating plate 2 139, an annular transmission plate 133 is rotatably mounted on the annular support frame 103, four sector racks 141 are fixedly arranged in a circular array on the annular transmission plate 133, the driven gear 137 is meshed with the corresponding sector rack 141 to form a gear rack pair, and the driven gear 2 140 forms a gear rack pair when engaged with the corresponding sector rack 141, a driving motor 142 is also fixedly mounted on the annular support frame 103, and the output shaft of the driving motor 142 is fixedly connected to the corresponding driven gear 137.

[0028] In the initial position, the four right-angled sector plates 132 are located at the position closest to the axis of the annular scraper 125. At this time, the four right-angled sector plates 132 are combined to form a circular support plate, that is, the four transmission short rods 135 are all located at the position closest to the axis of the annular scraper 125, and the four L-shaped slides 134 are located at the position farthest from the axis of the annular scraper 125. The sector racks 141 are not engaged with the corresponding driven gear 2 140. At this time, the torsion spring between the strip rotating plate 2 139 and the annular support frame 103 is not compressed, and the torsion spring between the driven gear 1 137 and the strip rotating plate 136 is not compressed.

[0029] refer to Figure 2 , Figure 3, start the driving motor 142 to drive the corresponding driven gear 137 to rotate counterclockwise, that is, the annular transmission plate 133 rotates counterclockwise, under the action of the annular transmission plate 133 and the sector rack 141, the four driven gears 137 rotate counterclockwise synchronously, under the action of the torsion spring between the bar rotating plate 136 and the driven gear 137, the bar rotating plate 136 rotates synchronously, that is, the four bar rotating plates 136 rotate counterclockwise synchronously, that is, the four transmission short rods 135 move away from the axis of the annular scraper 125, thereby causing the four right-angle sector plates 132 to move. Move in the direction away from the axis of the annular scraper 125, the upper surface of the right-angled sector plate 132 moves relative to the lower surface of the annular scraper 125, and the objects on the upper surface of the right-angled sector plate 132 are cleaned under the action of the annular scraper 125, and finally all four right-angled sector plates 132 move to the position farthest from the axis of the annular scraper 125. At this time, the right-angled sector plate 132 is completely located on the outside of the annular scraper 125, that is, the annular scraper 125 completes the cleaning of the upper surface of the right-angled sector plate 132, and at this time the sector rack 141 does not contact the driven gear 2 140.

[0030] refer to Figure 2 , Figure 3 , start the drive motor 142 to drive the corresponding driven gear 137 to rotate clockwise, that is, the annular transmission plate 133 rotates clockwise. Under the action of the annular transmission plate 133 and the sector rack 141, the four driven gears 137 rotate clockwise synchronously. Since the four right-angled sector plates 132 are located at the position closest to the axis of the annular scraper 125 at this time, the right-angled sector plates 132 cannot move further, and then the strip rotating plate 136 cannot rotate further. The strip rotating plate 136 and the driven gear 137 are in a state of rotation. The torsion springs between them are compressed, so that the sector racks 141 are in contact with the corresponding driven gears 140 respectively, and the annular transmission plate 133 continues to rotate, that is, the four sector racks 141 continue to rotate. Under the action of the sector racks 141, the driven gears 140 all rotate clockwise, that is, the four bar-shaped rotating plates 139 all rotate clockwise, thereby causing the four transmission short rods 138 to move toward the direction close to the axis of the annular scraper 125, that is, causing the four L-shaped slides 134 to move toward the direction close to the axis of the annular scraper 125.

[0033] The positioning unit includes a positioning ring plate 115 slidably mounted on an auxiliary ring frame 112, a positioning screw rod 127 is rotatably mounted on the auxiliary ring frame 112, the positioning ring plate 115 and the positioning screw rod 127 constitute a spiral pair, a positioning motor 126 is fixedly mounted on the auxiliary ring frame 112, the output shaft of the positioning motor 126 is fixedly connected to the positioning screw rod 127, four positioning strips 118 are fixedly arranged in a circular array on the positioning ring plate 115, a positioning short rod 119 is fixedly arranged on the end of the positioning strip 118 farthest from the circular bottom plate 101, and a positioning slide plate 121 is fixedly arranged on the positioning circular block 117, and the positioning short rod 119 is movably connected to the corresponding positioning slide plate 121.

[0034] In the initial position, the adjustment slot plate 121 is in a horizontal state, that is, the square pressing rod 122 is in a horizontal state. At this time, the adjustment ring plate 115 is located in the middle position of the adjustment screw rod 127, and the adjustment short rod 119 is located in the middle position of the adjustment slot plate 121.

[0035] Start the positioning motor 126 to drive the positioning screw 127 to rotate, so that the positioning ring plate 115 moves upward, and the four positioning strips 118 move upward synchronously, that is, the four positioning short rods 119 move upward synchronously. Under the action of the positioning short rod 119, the positioning round block 117 and the positioning slide plate 121 rotate synchronously, so that the pressing ball 120 and the square pressing rod 122 rotate synchronously, and the end of the positioning slide plate 121 farthest from the axis of the auxiliary ring frame 112 moves upward, that is, the end of the square pressing rod 122 farthest from the axis of the auxiliary ring frame 112 moves upward, and the end of the square pressing rod 122 closest to the axis of the auxiliary ring frame 112 moves downward.

[0036] Start the positioning motor 126 to drive the positioning screw 127 to rotate, so that the positioning ring plate 115 moves downward, and the four positioning strips 118 move downward synchronously, that is, the four positioning short rods 119 move downward synchronously. Under the action of the positioning short rod 119, the positioning round block 117 and the positioning slide plate 121 rotate synchronously, so that the pressing ball 120 and the square pressing rod 122 rotate synchronously, and the end of the positioning slide plate 121 farthest from the axis of the auxiliary ring frame 112 moves downward, that is, the end of the square pressing rod 122 farthest from the axis of the auxiliary ring frame 112 moves downward, and the end of the square pressing rod 122 closest to the axis of the auxiliary ring frame 112 moves upward, that is, by adjusting the position of the positioning ring plate 115, the angle of the square pressing rod 122 is adjusted.

[0037] The auxiliary ring frame 112 is also provided with four feed racks 113 slidably mounted in a circular array, and a strip slide plate 114 is fixedly mounted on the upper surface of the feed rack 113. A second adjustment short rod 123 is fixedly mounted on the end of the square pressing rod 122 farthest from the axis of the auxiliary ring frame 112, and the second adjustment short rod 123 is movably connected to the corresponding strip slide plate 114. A gear set is arranged between the four feed racks 113, and the gear set includes a transmission gear ring 131, four transmission gears 128, and four feed gears 129. , four transmission gears 128 are rotatably mounted in a circular array on the auxiliary ring frame 112, a transmission gear ring 131 is rotatably mounted on the auxiliary ring frame 112, the transmission gears 128 are all meshed with the auxiliary ring frame 112 to form a gear pair, a feed gear 129 is fixedly mounted on the corresponding transmission gear 128, the feed gear 129 is meshed with the corresponding feed rack 113 to form a gear rack pair, a feed motor 130 is fixedly mounted on the auxiliary ring frame 112, and an output shaft of the feed motor 130 is fixedly connected to the corresponding feed gear 129.

[0038] In the initial position, the square pressing rod 122 is in a horizontal state. At this time, the feed rack 113 and the strip slide plate 114 are located at the farthest position from the axis of the auxiliary ring frame 112, and the second adjustment short rod 123 is located in the middle position of the strip slide plate 114.

[0039] Start the feed motor 130 to drive the corresponding feed gear 129 to rotate, so that the corresponding transmission gear 128 rotates. Under the action of the transmission gear ring 131, the four transmission gears 128 rotate synchronously, thereby causing the four feed gears 129 to rotate synchronously, so that the four feed racks 113 move toward the direction close to the axis of the auxiliary ring frame 112, and the four strip slide plates 114 move toward the direction close to the axis of the auxiliary ring frame 112. Under the action of the positioning short rod 123, the four square pressing rods 122 move toward the direction close to the axis of the auxiliary ring frame 112, and the four pressing balls 120 move synchronously toward the direction close to the axis of the auxiliary ring frame 112.

[0040] When the positioning motor 126 is started to adjust the position of the positioning ring plate 115, that is, when the angle of the square pressing rod 122 is adjusted, the position of the positioning short rod 123 changes, and thus the feeding motor 130 is started synchronously to adjust the position of the feeding rack 113, that is, to adjust the position of the strip slide plate 114. At this time, the positioning short rod 123 moves relative to the strip slide plate 114, that is, the strip slide plate 114 compensates for the displacement caused by the rotation of the positioning short rod 123 relative to the axis of the positioning round block 117.

[0041] When the square pressing rod 122 is in an inclined state, the four strip slide plates 114 are driven to move toward the direction close to the axis of the auxiliary ring frame 112 , and under the action of the second adjusting short rod 123 , the square pressing rod 122 moves along the inclined direction of the square pressing rod 122 .

[0042] An annular slide plate 106 is slidably mounted on the circular base plate 101, an auxiliary screw rod 107 is rotatably mounted on the circular base plate 101, the auxiliary screw rod 107 and the annular slide plate 106 constitute a spiral pair, an auxiliary motor 108 is fixedly mounted on the circular base plate 101, the output shaft of the auxiliary motor 108 is fixedly connected to the auxiliary screw rod 107, an auxiliary gear ring 111 is rotatably mounted on the annular slide plate 106, an auxiliary ring frame 112 is fixedly mounted on the auxiliary gear ring 111, a transposition motor 109 is fixedly mounted on the annular slide plate 106, an auxiliary gear 110 is fixedly mounted on the output shaft of the transposition motor 109, the auxiliary gear 110 meshes with the auxiliary gear ring 111 to constitute a gear pair, the transposition motor 109 is started to drive the auxiliary gear 110 to rotate, that is, the auxiliary gear 110 is rotated relative to the annular slide plate 106, that is, the position of the auxiliary ring frame 112 relative to the axis of the circular base plate 101 can be adjusted.

[0043] In the initial position, the pressing ball 120 is located at the farthest position from the axis of the auxiliary ring frame 112. At this time, the pressing ball 120 is located on the outside of the annular transmission plate 133. At this time, the auxiliary motor 108 is started to drive the auxiliary screw 107 to rotate, so that when the annular slide plate 106 moves up and down relative to the circular bottom plate 101, the pressing ball 120 will not come into contact with the annular transmission plate 133 and the annular support frame 103.

[0044] Working principle: In the initial position, the annular slide plate 106 is located at the position closest to the lower surface of the circular bottom plate 101, and the four pressing balls 120 are located at the position farthest from the axis of the auxiliary ring frame 112. At this time, the pressing components are all located below the positioning components, so that it is convenient to place the lighting fixture on the circular support plate formed by the four right-angled fan-shaped plates 132. After the lighting fixture is placed on the circular support plate formed by the four right-angled fan-shaped plates 132, the driving motor 142 is started, so that the four driven gears 140 are driven to rotate. The four L-shaped slides 134 rotate, thereby causing the four L-shaped slides 134 to move toward the direction close to the axis of the annular scraper 125, and finally causing the end faces of the four L-shaped slides 134 to contact the lamp holder 104 of the lighting fixture. Under the action of the four L-shaped slides 134, the lamp holder 104 is fixed. The four L-shaped slides 134 continue to move to squeeze the lamp holder 104, that is, to detect the quality of the lamp holder 104, and adjust the position of the annular slide 106, so that the camera 124 monitors the lamp holder 104.

[0045] If the lamp holder 104 is deformed or damaged, the quality is unqualified. Then the annular slide 106 is returned to the initial position, and the drive motor 142 is started. The four L-shaped slides 134 are first moved to the position farthest from the axis of the annular scraper 125, and then the four right-angle fan plates 132 are moved to the position farthest from the axis of the annular scraper 125. The unqualified lighting fixture falls into the waste box 102 below. If the lamp holder 104 is damaged and the debris produced can also fall into the waste box 102 under the action of the annular scraper 125, so that the surface of the right-angle fan plate 132 is cleaned.

[0046] If the lamp holder 104 is not deformed or damaged, the quality of the lamp holder 104 is qualified, and then the auxiliary motor 108 is started to adjust the position of the annular slide 106, that is, adjust the position of the pressing ball 120 relative to the bulb 105, and then start the feed motor 130 to make the four square pressing rods 122 move toward the direction close to the axis of the auxiliary ring frame 112, that is, make the four pressing balls 120 move toward the direction close to the axis of the auxiliary ring frame 112, so that the four pressing balls 120 first contact the surface of the bulb 105, and the four pressing balls 120 continue to move to press the bulb 105 to monitor, that is, to detect the quality of the bulb 105. If it is damaged, repeat the above steps and drop the lighting fixture into the waste box 102 below.

[0047] By starting the positioning motor 126 to adjust the positions of the positioning circle 117 and the positioning slide plate 121, that is, adjusting the inclination of the square pressing rod 122, and by starting the switching motor 109 to adjust the position of the auxiliary gear ring 111, the pressing position of the pressing ball 120 when detecting the light bulb 105 is adjusted. By repeating the above steps, multiple positions of the light bulb 105 can be pressed and detected.

[0048] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
