Description

Technical Field

[0001] The invention relates to the technical field of valve detection systems, and in particular to a rod degreasing device. Background Art

[0002] The valve is mainly responsible for inputting fuel into the engine and discharging exhaust gas, so the quality of the valve will directly affect the engine's intake and exhaust, and then affect the engine's working efficiency. Therefore, after the valve is produced, the quality of the valve is usually tested. The usual range of testing is from its valve head to the valve stem. The testing method is to manually observe the integrity of the valve, and then check the width of the valve seat, the width of the valve cone surface, and the valve margin with a ruler, and then use a micrometer to measure the roundness of the valve seat, and finally test the concentricity of the valve and the valve seat. It can be seen that the manual testing process is complicated and the testing efficiency is low.

[0003] In order to improve efficiency, testing equipment is also used for testing. However, whether it is manual testing or mechanical equipment testing, the valve stem needs to be degreased before testing. Especially the valve stem, which is a curved surface, is difficult to degrease. Generally, it is wiped manually, but manual wiping is inefficient and requires high wiping consumables.

[0040] Example 1

[0041] See also Figures 1 to 29 As shown; the first step: degreasing the valve stem and disc, this step specifically includes degreasing the valve stem and the valve disc, and taking photos of the disc appearance for inspection. The specific degreasing process is as follows:

[0042] 1) Degreasing the valve stem. The valves to be tested are inserted into the degreasing guide rail 100 one by one, and then the valves are moved from the degreasing guide rail 100 into the diverter positioning structure 200 by their own gravity. A stem degreasing device 300 is provided beside the diverter positioning structure 200, and valve suction cup rotating structures 400 are provided above the diverter positioning structure 200 and the stem degreasing device 300. The valve suction cup rotating structure 400 is arranged on the movable frame 500, and can move left and right between the diverter positioning structure 200 and the rod deoiler 300. When the valve enters the diverter positioning structure 200, the valve suction cup rotating structure 400 located above the diverter positioning structure 200 moves downward, sucks the valve, and then moves to the top of the rod deoiler 300. Then the valve suction cup rotating structure 400 moves downward, driving the valve stem to be inserted into the deoiler 300. After the oil suction is completed, it is driven by the valve suction cup rotating structure 400 to move to the next inspection station. This station is connected to the next station through the water flow track 600. A blocker 700 is provided on the side of the water flow track 600. The blocker 700 is used to control the number and speed of the valves entering the next process.

[0043] Specifically, the moving frame 500 includes a transverse rodless cylinder 501 and a longitudinal rodless cylinder 502. The longitudinal rodless cylinder 501 is fixed on the sliding bearing of the transverse rodless cylinder 501 through an oil suction cylinder connecting plate 503. A transverse oil suction cup seat 504 is provided on the sliding bearing of the longitudinal rodless cylinder 502. Two valve suction cup rotating structures 400 are arranged in parallel on the transverse oil suction cup seat 504. When in use, the transverse rodless cylinder 501 controls the valve suction cup rotating structure 400 to drive the valve to move transversely; the longitudinal rodless cylinder 502 controls the valve suction cup rotating structure 400 to drive the valve to move longitudinally, thereby realizing the valve to flow between the diversion positioning structure 200 and the rod deoiler 300.

[0044] like Figures 5 to 8 As shown, the flow dividing and positioning structure 200 includes a dividing block 201, and a semi-open dividing groove 202 is provided on the dividing block 201. The width of the semi-open dividing groove 202 is greater than the diameter of the valve stem and smaller than the diameter of the valve disc. One dividing block can only allow one valve to enter, thereby realizing the function of dividing. At the same time, after the valve enters the dividing block 201, the valve disc is located above the dividing block 201, and the valve stem is located below the dividing block 201, which is convenient for the valve suction cup rotating structure 400 to suck the valve. More preferably, the upper part of the groove surface of the semi-open dividing groove 202 is set as an inclined surface to adapt to the shape of the valve, increase the contact area between the valve and the dividing block, and facilitate the coordination of the rod clamp 209 and the clamping assembly 203 to firmly fix the valve in the flow dividing and positioning structure 200.

[0045] The valve dividing block 201 is arranged on the dividing bracket 204, which, on the one hand, leaves space for the valve stem, and on the other hand, enables the dividing and positioning structure 200 to be assembled with the stem deoiler 300 and the valve suction cup rotating structure 400 thereon. Specifically, the material dividing bracket 204 includes a material dividing bottom plate 204a, and a material dividing support plate 204b arranged on the material dividing bottom plate 204a, a material dividing top plate 204c is arranged on the material dividing support plate 204b, and the material dividing block 201 is arranged above the material dividing top plate 204c, and the material dividing top plate 204c is provided with a makeshift groove 207 corresponding to the semi-open material dividing groove 202, so as to facilitate the valve to enter the material dividing block, and an assembly line support plate 208 is provided at the end of the material dividing top plate 204c, and the assembly line support plate 208 is provided with a makeshift channel corresponding to the makeshift groove 207. Through the assembly line support 208, the diversion positioning structure 200 is convenient to cooperate with the de-oiling track in the valve visual inspection system, thereby completing the material dividing.

[0046] A rod clamp 209 is provided on the inner side of the material distribution support plate 204b, and the rod clamp 209 is located below the material distribution top plate 204c. A clamping assembly 203 is provided beside the rod clamp 209, and the clamping assembly 203 includes a clamping block 203a, which is arranged on a rotary cylinder 203b. The rotary cylinder 203b drives the clamping block 203a to rotate, so that the clamping block 203a is pressed against the valve stem, so that the valve stem is close to the rod clamp 209. In addition, in order to stably connect the clamping assembly 203 and the material distribution top plate 204 to the material distribution support, a support rod 205 is provided between the clamping assembly 203 and the material distribution bottom plate 204a, and between the material distribution top plate 204c and the material distribution bottom plate 204a.

[0047] More preferably, a rubber pressing block 206 is provided on the pressing surface of the pressing block 203a. Since the valve is provided with engine oil, the rubber pressing block 206 contacts the valve stem, which can increase friction on the one hand, making the valve abutment more stable. Secondly, when the valve is extracted from the station, the rubber pressing block 206 can scrape off the oil on part of the valve stem. More preferably, the rod clamping member 209 includes an upper clamping block 209a and a lower clamping block 209b with the same structure and relatively arranged. The upper clamping block 209a and the lower clamping block 209b are connected by a clamping connection block 209c, and the upper clamping block 209a and the lower clamping block 209b are both provided with a V-shaped clamping groove. The rubber pressing block 206 and the clamping connection block 209c are located at the same horizontal plane. The valve stem is directly contacted by the rubber pressing block 206, and then the valve stem is clamped in the V-shaped narrow groove between the upper and lower clamping blocks, so that the stability of the valve stem clamping can be ensured. Preferably, the upper clamping block 209a and the lower clamping block 209b may also be made of rubber, which is helpful to scrape off the oil on the rod and further enhance the stability of the clamping.

[0048] like Figures 9 to 17 As shown, it includes an oil removal block 301, on which a rod oil removal insertion hole 302 is provided, and an oil removal chamber 303 is provided in the oil removal block 301, and an oil scraper 305 and a sealing member 306 are provided in the oil removal chamber 303, and both the oil scraper 305 and the sealing member 306 are provided with a rod insertion hole 307 connected to the oil removal insertion hole 302; the sealing member 306 is arranged at the bottom of the oil removal chamber 303, and the oil scraper 305 is arranged above the sealing member 306;

[0049] The oil removal chamber 303 is connected to an oil pump assembly hole 304 on the side. In order to ensure that the scraped oil can be smoothly pumped away by the vacuum pump, the scraper plate 305 and the oil removal chamber 303 are clearance-matched. A guide member 308 is provided between the scraper plate 305 and the seal 306, and a rod avoidance hole 308c is provided on the guide member 308 corresponding to the rod insertion hole 307. The guide member 308 includes a guide body 308a, and guide blocks 308b are evenly provided on both sides of the guide body 308a. Multiple oil outlet channels are formed between the guide blocks to prevent the oil from concentrating and flowing away from a certain direction, so that the scraped oil can be orderly pumped out through the oil outlet channel to prevent excessive flow on one side, resulting in uneven scraping of the oil.

[0050] The guide block 308b is arranged at the middle circle position of the guide body 308a, ensuring that the guide block 308b has a certain distance from the rod avoidance hole 308c and the de-oiling chamber 303, and leaving a space for temporary storage of oil from the rod avoidance hole 308c to avoid the situation that the space is insufficient and the oil is not scraped cleanly; at the same time, when the valve stem is inserted, the scraper plate 305 is deformed, and a deformation buffer space is also left for the scraper plate 305 to prevent the scraper plate 305 from being damaged. Due to the deformation space, the difficulty of valve insertion is also reduced. More preferably, in order to protect the scraper plate 305, the diameter of the rod avoidance hole 308c is slightly larger than the diameter of the valve stem, so that the scraper plate 305 has multiple deformation buffer positions, further reducing the difficulty of valve insertion. Leaving space with the de-oiling chamber 303 is to form a closed annular oil outlet channel, so that the diverted oil can circulate in the oil outlet channel, making it easy to extract the oil.

[0051] In order to facilitate the flow diversion, the inner side of the guide block 308b is arc-shaped. The guide block 308b is provided with an oil scraper 305 on the upper and lower sides, so that the valve stem is inserted once and the oil is scraped four times, further ensuring the cleanliness of the valve oil scraping. The top surface of the deoiling chamber 303 is also provided with a guide block 308b, so that the oil scraper and the upper chamber of the deoiling chamber 303 leave space, which is convenient for oil scraping and guiding, so as to further ensure the cleanliness of the oil scraping. The shape of the deoiling insertion hole 302 is adapted to the shape of the valve, and the deoiling chamber 303 can be sealed by the valve to ensure the airtightness of the deoiling chamber. It provides a guarantee for the reliability of oil extraction, and at the same time, it can also preliminarily detect the airtightness of the valve.

[0052] In order to improve the oil scraping effect, the oil scraper 305 is made of rubber. In order to facilitate the rod deoiler 300 to cooperate with other components, the deoiling block 301 is fixedly set on the rod deoiling tooling assembly 309, and the rod deoiling tooling assembly 309 includes a rod deoiling component support bottom plate 309a and a rod deoiling component support top plate 309b, and the rod deoiling support bottom plate 309a and the rod deoiling support top plate 309b are connected by a rod deoiling support rod 309c; the deoiling block 301 is set on the rod deoiling component support top plate 309b, and the rod deoiling component support top plate 309b is provided with a rod clearance hole 309d.

[0053] Specifically, the valve suction cup rotating structure 400 has two structures, which are respectively recorded as a type I valve suction cup rotating structure and a type II valve suction cup rotating structure. A type I valve suction cup rotating structure includes a vacuum suction cup assembly 401,

[0054] Another type II valve suction cup rotating structure includes a vacuum suction cup assembly 401 .

[0055] 2) Suck oil from the upper surface of the valve disc and take a photo to check the appearance and size of the upper surface.

[0056] The valve after deoiling by the front rod deoiler 300 enters the transition connection device 3 through the water flow track 600. The transition connection device includes the aforementioned diverter positioning structure 200, the disc detection rodless cylinder 31, the disc oil suction nozzle 32, and the disc camera device 33. The diverter positioning structure 200 is arranged on the sliding bearing of the disc detection rodless cylinder. The disc oil suction nozzle 32 and the disc camera device 33 are both arranged above the disc detection rodless cylinder 31. The disc oil suction nozzle 32 is located at the front end of the disc camera device 33. , the oil on the upper surface of the valve disc is first sucked, and then the disc appearance is checked for defects through a photographing device. More preferably, the disc oil suction nozzle 32 is close to the end of the disc detection rodless cylinder 31 and connected to the end of the water flow track 600; at the same time, the disc photographing device 33 is located in the middle of the disc detection rodless cylinder 31, and the disc photographing device 33 is located in the middle of the disc detection rodless cylinder 31, so that the valve can be fed, photographed, and discharged in the disc detection rodless cylinder 31. When the valve just enters the transition connection device 3, the shunt positioning structure 200 is located at the head end of the disc detection rodless cylinder 31. The valve is directly fixed on the shunt positioning structure 200 after passing through the water flow track 600. Then the disc oil suction nozzle 32 moves down to absorb the oil on the upper surface of the valve disc. Then the disc detection rodless cylinder 31 is started to move the shunt positioning structure 200 to the bottom of the disc camera device 33 to complete the photo taking and detection. Then the disc detection rodless cylinder 31 is started again to drive the shunt positioning structure 200 to move to the other end of the disc detection rodless cylinder to prepare for the valve to enter the next detection device. Finally, the disc detection rodless cylinder 31 is reset to prepare for the next valve detection.

[0057] Step 3: Inspect the local appearance, overall appearance and local dimensions of the valve by taking photos. Specific inspections include the appearance of the valve lock groove, the appearance of the valve line, the appearance of the stem, the stem diameter, the size of the lock groove, the outer diameter, the total length of the valve, the appearance of the small end face of the valve, and the appearance of the R line of the disc.

[0058] The detection device is divided into an upper detection device and a lower detection device. Among them, the upper detection device is a valve suction cup rotating and moving device, which includes a type I valve suction cup rotating structure, a type II valve suction cup rotating structure and a two-axis module 411.

Specifically, the valve suction cup rotating structure 400 is evenly arranged on the valve suction cup rotating structure mounting seat 410. In this embodiment, four valve suction cup rotating structures 400 are arranged on the valve suction cup rotating structure mounting seat 410. The three valve suction cup rotating structures 400 located in the front adopt type I valve suction cup rotating structure, and the valve suction cup rotating structure mounting seat 410 located at the end adopts type II valve suction cup rotating structure. Among them, the type I valve suction cup rotating structure is fixed on the valve suction cup rotating structure mounting seat 410 through the suction cup mounting seat 404, and its power output structure 407 is arranged in parallel with the main structure, which is beneficial to the master and driven wheel transmission.

Preferably, the power element 1203 adopts a cylinder, and the rotational positioning block 1201 is driven by the cylinder to move on the sliding assembly 1202 until the rotational positioning block 1201 abuts against the rotating wheel 1204, fixes the valve clamped on the rotational positioning block 1201, and then the rotating wheel 1204 rotates to drive the valve to rotate. Specifically, the sliding assembly 1202 includes a slide rail 1202a, and a slider 1202b is arranged on the slide rail 1202a, and the rotational positioning block 1201 is fixed on the slider 1202b through a connecting seat 1205.

[0061] More preferably, a rubber ring 1204b is embedded on the circumference of the rotating wheel 1204, which can buffer the impact of the power element 1203 on the one hand, and help drive the valve to rotate on the other hand. In the present invention, the rotating wheel 1204 is arranged at the power output end of the progressive motor. The rotating wheel 1204 is arranged on the pressure plate 1206, and the two ends of the pressure plate 1206 are arranged on the slide rail 1202a through the slider 1202b, so that the rotating wheel 1204 can slide relative to the slide rail, and then adjust the position of the rotating wheel 1204 relative to the rotation positioning block 1201 to adapt to valves of different sizes, thereby improving the applicability of the present invention. In order to relatively fix the position between the rotating wheel 1204 and the rotation positioning block 1201.

A rod diameter wall plate 1305 is passed between the rod diameter base plate 1303 and the rod diameter cover plate 1304. A transfer block 1306 is arranged on the rod diameter cover plate 1304. A valve suspension hole 1307 is opened on the transfer block 1306. A rod diameter cover plate 1304 is provided with a rod diameter corresponding to the valve suspension hole. diameter giving hole; the dimension measuring instrument 1301 is installed on the rod diameter wall plate 1305, and the dimension measuring instrument 1301 includes a left-side measuring laser unit 1308 and a right-side measuring laser unit 1309, and a laser detection area is formed between the left-side measuring laser unit 1308 and the right-side measuring laser unit 1309, and the left-side measuring laser unit 1308 and the right-side measuring laser unit 1309 are relatively arranged on the left and right sides of the rod diameter cover plate 1304, and the overall position of the left-side measuring laser unit 1308 and the right-side measuring laser unit 1309 is lower than the lower surface of the rod diameter cover plate 1304, so that the laser detection area passes through the bottom of the valve suspension hole 1307.

[0066] Specifically, the left-side measuring laser unit 1308 and the right-side measuring laser unit 1309 are fixed at both ends of the laser unit connection block 1310, and the middle part of the laser unit connection block 1310 is fixed on the rod diameter wall plate 1305. In order to improve the strength of the rod diameter measuring support 1302 structure, the rod diameter wall plate 1305 is connected to one side of the rod diameter base plate 1303 and the rod diameter cover plate 1304, and the rod diameter base plate 1303 and the rod diameter cover plate 1304 are fixedly connected on the opposite side by the rod diameter support rod 1311; at the same time, the connection through the rod diameter support rod 1311 not only ensures the structural strength, but also facilitates the observation of the valve stem. More preferably, the upper part of the inner circle of the valve suspension hole 1307 is umbrella-shaped, which is convenient for matching with the shape of the valve and is beneficial for the stable placement of the valve. More preferably, the valve suspension hole 1307 is slightly larger than the valve size, due to the insertion of the valve stem.

[0067] When in use, the valve is inserted into the transfer block 1306, and the stem of the valve passes through the transfer block 1306 and the stem diameter cover plate 1304. At this time, the stem of the valve passes through the laser surface between the left measuring laser part 1308 and the right measuring laser part 1309, and the diameter of the valve stem can be detected by the size measuring instrument 1301. If it is matched with the valve suction cup rotating and moving device, the size of the valve lock clamp groove can also be measured. When in use, the valve is sucked up by the valve suction cup rotating structure 400 on the valve suction cup rotating and moving device, and moved to the top of the valve stem diameter detection structure 1300, and the valve is sucked by the valve suction cup rotating structure 400, so that the lock clamp groove of the valve is located on the laser detection surface, and the size of the valve lock clamp groove can be detected by the size measuring instrument 1301. After the lock clamp groove detection is completed, the valve is directly placed in the transfer block 1306, and then the valve diameter is detected by the size measuring instrument 1301.

[0068] Specifically, the specific structure of the valve total length detection structure is as follows. Figures 24 to 25 As shown, a valve total length detection structure includes a total length detection base 1402, which includes an upper base plate 1402a and a lower base plate 1402b; a valve mounting hole 1402c is provided on the upper base plate 1402a, and a rotary clamping cylinder 1401 is provided beside the valve mounting hole 1402c; a detection head 1404 is provided on the lower base plate 1402b, and the detection head 1404 is located directly below the valve mounting hole 1402c; the detection head 1404 is connected to a linear displacement sensor through an electronic ruler connecting plate 1405; and the end of the detection head 1404 is fixedly connected to a displacement power element 1406. The linear displacement sensor used in the present invention is a KPM-100mm micro articulated linear displacement sensor.

[0069] Specifically, the rotary clamping cylinder 1401 includes a cylinder body and a telescopic rotating part, wherein the cylinder body is located on the lower surface of the upper base plate 1402a, and the telescopic rotating part is located on the upper surface of the upper base plate 1402a. This is beneficial to shortening the telescopic length of the rotary clamping cylinder 1401, facilitating assembly and effectively reducing manufacturing costs. A total length pressure head 1403 is provided at the end of the telescopic rotating part, and the end surface of the total length pressure head 1403 is flat, and the end surface size of the total length pressure head 1403 is larger than the large circle diameter of the cylinder. This is beneficial to improving the reliability of the pressure head clamping the cylinder.

[0070] The power output rod of the displacement power element 1406 is threadedly connected to the end of the detection head 1404. Specifically, the displacement power element 1406 is an electric cylinder, and the telescopic rod of the cylinder is threadedly connected to the end of the detection head 1404, which is convenient for removing the detection head from under the cylinder and replacing the detection head damaged during use. More preferably, a valve mounting seat 1407 is provided on the upper base plate 1402a, and a valve fixing hole is provided at the position corresponding to the valve mounting hole 1402c on the valve mounting seat 1407. By using the valve mounting seat as a transition piece for detecting the total length of the valve, it is possible to prevent the rotary clamping cylinder 1401 from being directly pressed on the upper base plate 1402a, thereby protecting the total length detection base. In addition, the valve mounting seat 1407 is used as a consumable part. When the valve mounting seat is damaged, it is easy to replace, thereby reducing the subsequent use cost.

[0071] The upper substrate 1402a and the lower substrate 1402b are connected by support columns 1408. The upper substrate 1402a and the lower substrate 1402b are connected by four support columns 1408, which is convenient for observing the detection situation and improving the convenience of use. An electronic ruler mounting plate 1409 is provided on the side of the lower substrate 1402b. It is convenient to install a linear displacement sensor. The lower substrate 1402b is arranged on the transfer seat 1410. It is beneficial to make the valve total length detection structure and other processes of the valve detection system located on the detection line at the same height, thereby improving the applicability of the valve total length detection structure.

[0072] When in use, place the valve in the valve mounting hole 1402c, then start the rotary clamping cylinder 1401 to reduce the valve pressure, and then start the linear displacement sensor and the cylinder connected to the detection head at the same time. The cylinder drives the detection head to move upward, so that the detection head abuts against the lower end of the valve. At the same time, the linear displacement sensor detects the displacement of the detection head, and then calculates the total length of the valve. In conjunction with the valve suction cup rotating moving device, the valve is sucked and inserted through the valve suction cup rotating structure 400, realizing the function of automatically detecting the total length of the valve, and it is also convenient to cooperate with other detection stations.

[0073] Since the entire system detection involves many positions that need to be photographed and detected, the lighting requirements are relatively high. For this reason, the system also involves upper and lower light source brackets, and light sources are set on the upper and lower light source brackets to provide lighting for the entire system. Specifically, the upper and lower light source brackets are set between the valve stem diameter detection structure 1300 and the door total length detection structure 1400.

[0074] The specific structure of the upper and lower light source brackets 1600 is as follows: Figure 26 to Figure 28As shown, an upper and lower light source bracket includes an upper light source bracket 1601 and a lower light source bracket; the upper light source bracket 1601 includes two symmetrically arranged upper light source support plates 1601a; the lower light source bracket includes a lower light source fixing frame 1603, a lower light source support plate 1604 is provided in the lower light source fixing frame 1603, and a light source angle adjustment frame 1605 is provided below the lower light source support plate 1604; the two upper light source support plates 1601a are respectively fixed on the left and right side plates 1603a of the lower light source fixing frame 1603, and the upper light source support plate 1601a can rotate relative to the left and right side plates 1603a.

[0075] The upper light source support plate 1601a and the side plate 1603a are assembled and connected at the arc-shaped fixing groove 1601b and the bolt assembly hole 1601c. By opening two bolt installation holes at the positions of the side plate 1603a corresponding to the arc-shaped fixing groove 1601b and the bolt assembly hole 1601c, the upper light source support plate 1601a is rotated relative to the side plate 1603a with the bolt as the rotation axis, and then after the rotation finds the appropriate position, another bolt is passed through the arc-shaped fixing groove 1601b and the bolt installation hole on the side plate 1603a to fix the position of the upper light source support plate 1601a and the side plate 1603a, thereby adjusting the irradiation angle of the light source located on the upper light source support plate 1601a.

[0076] The light source angle adjustment frame 1605 includes two relatively arranged lower lifting guide rails 16051, and the lower lifting guide rails 16051 are respectively provided with lifting guide rod mounting grooves 16052 and lifting guide rail mounting holes 16053, a movable lifting guide rod 16055 is provided between the lifting guide rod mounting grooves 16052 on the two lower lifting guide rails 16051, and a fixed lifting guide rod 16054 is provided between the lifting guide rail mounting holes 16053 on the two lower lifting guide rails 16051; two upper lifting guide rails 16056 are correspondingly provided above the two lower lifting guide rails 16051, the upper lifting guide rails 16056 are fixedly connected to the lower light source support plate 1604, and the structure of the upper lifting guide rail 16056 is the same as that of the lower lifting guide rail 16051.

[0077] The movable lifting guide rod 16055 on the lower lifting guide rail 16051 and the fixed lifting guide rod 16054 on the upper lifting guide rail 16056 are connected by a lifting link 16057. The lifting links 16057 on the same side are provided with guide rod mounting holes at their intersections, and the two guide rod mounting holes are connected by a middle lifting guide rod 16058. When the movable lifting guide rod 16055 moves in the lifting guide rod mounting groove 16052 and the fixed lifting guide rod 16054 remains stationary, the movable lifting guide rod 16055 drives the lifting link 16057 to move up and down, thereby tilting the light source, thereby achieving the function of adjusting the light source.

[0078] The movable lifting guide rod 16055 is vertically connected to the lifting screw 1606, and both ends of the lifting screw 1606 are respectively connected to the lifting screw seat 1607. By adjusting the distance between the lifting screw 1606 and the movable lifting guide rod 16055, the position of the movable lifting guide rod 16055 in the lifting guide rod installation groove 16052 is controlled, thereby controlling the angle of the light source located on the lower light source support plate 1604.

[0079] A hand-tightening nut 1608 is provided at the end of the lifting screw 1606. This is conducive to manually adjusting the angle of the light source. The lower lifting guide rail 16051 is arranged on the bottom plate 1603b of the lower light source fixing frame 1603. The lower light source fixing frame 1603 is fixed on the light source support seat 1609. This facilitates the installation of the upper and lower light sources at places where supplementary light is needed for taking photos.

[0080] The light source support seat 1609 includes a base support frame 1610, on which a rodless cylinder 1611 is provided, and the lower light source fixing frame 1603 is connected to the screw bearing of the rodless cylinder 1611 through a light source connecting plate 1612. The upper and lower light sources can be set up at the shooting position where fill light is needed through the base support frame 1610, and the distance between the upper and lower light sources and the fill light position can be adjusted through the rodless cylinder 1611, so that the space of the shooting position is not occupied and fill light can be provided. The light source connecting plate 1612 is located on one side of the bottom plate 1603b. The upper and lower light sources are fixed vertically to the support seat, which not only makes way for shooting, but also can accurately fill light.

[0081] The above detailed description of the invention has been made with many modifications and variations to the inventive concept. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the invention on the basis of the prior art should be within the scope of protection determined by the claims.
