In the default state, the supporting column is located at a high position and its top is flush with the supporting seat. When the contact wheel rotates to drive the two supporting seats to swing away from each other, the contact wheel drives the supporting column to slide vertically downward to support the material tray to descend into the clamping arc groove.

[0014] Preferably, an adjustment assembly is further included, which includes a locking rod and an adjustment rod. The locking rod is horizontally slidably arranged on the lifting seat. The adjustment rod is driven to rotate to drive the locking rod to slide horizontally relative to the vertical projection position of the spectrum probe. An interference groove is provided on the lifting column.

[0019] A developer detection method, comprising the developer visual inspection device described in the above scheme, comprises the following specific steps:

[0020] S1. First, pour equal amounts of different developer solutions into several trays, cover the trays, and then place the trays on different placement seats.

[0021] S2. The driving moving belt aligns a placement seat with the lifting seat and then stops. The lifting seat drives the supporting seat to lift vertically to pass through the through slot. The supporting seat rises to lift the material tray on the placement seat. As the lifting seat continues to lift, the contact wheel rolls against the side wall of the through slot to make the supporting seat swing away relatively. The contact wheel also drives the lifting column to descend through the driving seat. At this time, the top of the supporting column generates suction to adsorb the material tray. Then the supporting column descends vertically to support the material tray into the clamping arc slot.

[0022] S3. The sliding seat drives the supporting seat and the material tray to move horizontally toward the vertically downward side of the spectrum probe, and the supporting seat approaches the stabilizing wheel so that the stabilizing wheel rolls and abuts against the entry groove. The arched portion of the entry groove squeezes the stabilizing wheel so that the supporting seat swings closer due to the reaction force to clamp the peripheral side of the material tray. The material tray is squeezed by the supporting seat to apply pressure to the rubber block. The elastic plate inside the rubber block stores energy and then deforms and releases it to make the material tray rotate rapidly axially, thereby throwing the droplets on the top wall of the material tray to the peripheral side.

[0023] S4, until the sliding seat slides until the lifting column on it contacts the locking rod, the sliding seat stops sliding, and the material tray and the spectrum probe are vertically aligned;

[0024] S5. The developer in the tray is inspected by the spectral probe. After the inspection is completed, the sliding seat slides back to the original position, driving the tray close to the placement seat. Then the lifting seat descends vertically to lift the tray through the contact wheel and the driving seat, and the supporting column drives the tray. The supporting seat swings relatively close to reset. Then, the inspected tray falls on the placement seat, and the lifting seat descends to the lowest position.

[0025] S6. Repeat steps S2-S5 to inspect the developer inside the material tray placed on each placement seat.

[0026] In the above technical scheme, the present invention provides a developer visual inspection device and detection method, which have the following beneficial effects: a moving belt is used to drive several placement seats and material trays to move in a waist-shaped circular motion, and the lifting seat and the sliding seat are staggered with the moving belt to realize the lifting and horizontal transportation of each material tray. While realizing the automatic transportation and inspection of multiple material trays, it also avoids the problem of the material tray sliding and falling off due to the rotation stroke during the transportation of the material tray, thereby improving the transportation stability of the material tray.

DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0044] like Figure 1-13 As shown, a developer visual inspection device and detection method includes a base 1, which is provided with:

[0045] Spectral probe 111;

[0046] The placement component includes a waist-shaped circular rotating moving belt 22, a placement seat 23 for placing the material tray 91 is provided on the moving belt 22, and a through slot 231 is opened on the placement seat 23;

[0047] A lifting seat 31 is arranged to slide vertically. A conveying assembly is provided on the lifting seat 31. The conveying assembly includes a sliding seat 41 with a horizontal sliding stroke. A supporting seat 42 is provided on the sliding seat 41.

[0048] Among them, the lifting seat 31 is lifted vertically to a high position so that the supporting seat 42 is lifted through the slot 231 to support the material tray 91, and the sliding seat 41 is driven to slide toward the first end of the stroke to drive the supporting seat 42 and the material tray 91 to move toward the vertical lower side of the spectral probe 111.

[0049] Specifically, such as Figure 1 As shown, a spectrum probe 111 is provided on the detection portion 11 of the base 1, and two rotating rollers 21 are also rotatably provided on the base 1, as shown in FIG. Figure 1 As shown, the moving belt 22 is simultaneously sleeved on the rotating roller 21 to form a waist-shaped circle, and the rotating roller 21 rotates to drive the moving belt 22 to drive the placement seat 23 to perform waist-shaped circular movement, and a material tray 91 can be placed on the placement seat 23, and the material tray 91 can be placed in the developer, and the upper side of the material tray 91 has a transparent shielding cover to prevent the developer from leaking, and a driving cylinder 32 is further provided in the base 1 to drive the lifting seat 31 to slide vertically, and the sliding seat 41 is slidably provided in the horizontal slide groove 311 of the lifting seat 31, and the first end of the sliding stroke of the sliding seat 41 is located on the side of the lifting seat 31 close to the spectrum probe 111, and the second end of the sliding stroke of the sliding seat 41 is located on the side of the lifting seat 31 close to the moving belt 22, and as shown Figure 1 As shown, at this time, the sliding seat 41 is located at the second end of the sliding stroke;

[0050] When inspection is required, equal amounts of different developer solutions are first poured into several trays 91, and the trays 91 are covered. The trays 91 are then placed on different placement seats 23. The rotating roller 21 then drives the moving belt 22 to align a placement seat 23 with the lifting seat 31 and then stops. The driving cylinder 32 drives the lifting seat 31 to lift the supporting seat 42 vertically so that it passes through the slot 231. The supporting seat 42 rises to lift the tray 91 on the placement seat 23. The sliding seat 41 then slides horizontally to move the supporting seat 42 and the tray 91 toward the vertically downward side of the spectrometer probe 111. The spectrometer probe 111 is then used to visually inspect the tray 91 below. The lifting seat 31 and sliding seat 41 are used to lift and horizontally transport the tray 91, avoiding the problem of the tray 91 sliding and falling due to the rotational travel during transportation, thereby improving the transportation stability of the tray 91.

[0051] When the spectral probe 111 completes the inspection of the material tray 91, the sliding seat 41 slides and resets to the second end of the sliding stroke, so that the sliding seat 41 drives the supporting seat 42 and the material tray 91 to slide horizontally and reset to above the placement seat 23, and then the lifting seat 31 is vertically lowered to a low position so that the sliding seat 41 and the supporting seat 42 pass through the slot 231, and the material tray 91 is placed back on the placement seat 23. At this time, the moving belt 22 can be driven to move so that the other placement seat 23 moves to be aligned with the lifting seat 31, and then the material tray 91 on the placement seat 23 can be transported and inspected.

[0052] Among them, the conveying component also includes a threaded drive column 43 that is horizontally rotated and arranged on the lifting seat 31, and the threaded drive column 43 is threadedly matched with the sliding seat 41. The threaded drive column 43 is rotated to drive the sliding seat 41 and the supporting seat 42 to slide horizontally, thereby improving the horizontal sliding stability of the sliding seat 41.

[0053] In the above technical solution, a moving belt 22 is used to drive several placement seats 23 and material trays 91 to move in a waist-shaped circular motion, and the lifting seat 31 and the sliding seat 41 run alternately with the moving belt 22 to realize the lifting and horizontal transportation of each material tray 91. While realizing the automatic transportation and detection of multiple material trays 91, it also avoids the problem of the material tray 91 sliding and falling off due to the rotation stroke during the transportation of the material tray 91, thereby improving the transportation stability of the material tray 91.

[0054] As another embodiment provided by the present invention, a driving assembly 5 is provided on the lifting seat 31, and the driving assembly 5 includes contact wheels 51 symmetrically arranged on both sides of the lifting seat 31 for rotation, and the supporting seat 42 symmetrically swingingly arranged on the sliding seat 41, and a clamping arc groove 421 is opened on the supporting seat 42. The lifting seat 31 is vertically lifted to a high position so that the contact wheel 51 rolls against the side wall of the groove 231, and the contact wheel 51 rotates to drive the two supporting seats 42 to swing away from each other so that the material tray 91 falls into the clamping arc groove 421.

[0055] Specifically, such as Figure 3 As shown, the contact wheels 51 are arranged on both sides of the lifting seat 31 in the horizontal direction, and the supporting seats 42 are symmetrically swingingly arranged on the sliding seat 41. When the moving belt 22 moves so that a certain placement seat 23 is aligned with the lifting seat 31, the lifting seat 31 can slide to a high position. After the lifting seat 31 drives the supporting seat 42 to lift vertically to hold up the material tray 91, as the lifting seat 31 continues to rise, the contact wheels 51 of the lifting seat 31 contact the side wall of the through slot 231 of the placement seat 23 and move forward. The contact wheel 51 rolls and drives the supporting seat 42 to swing away relatively, so that the material tray 91 falls between the clamping arc grooves 421 of the two supporting seats 42, thereby utilizing the contact wheel 51 and the clamping arc grooves 421 of the supporting seat 42 to limit the material tray 91 circumferentially, avoiding the problem that the sliding seat 41 moves horizontally to transport the material tray 91 and causes the material tray 91 to fall off the supporting seat 42, thereby improving the support and limiting stability of the supporting seat 42 on the material tray 91.

[0056] As another embodiment provided by the present invention, a supporting column 71 is vertically slidably provided on the sliding seat 41. In the default state, the supporting column 71 is located at a high position and its top end is flush with the supporting seat 42. When the contact wheel 51 rotates to drive the two supporting seats 42 to swing away from each other, the contact wheel 51 drives the supporting column 71 to slide vertically downward to support the material tray 91 to descend into the clamping arc groove 421.

[0057] Specifically, such as Figure 6As shown, a supporting column 71 is further provided on the sliding seat 41. The supporting column 71 is in a high position in the default state, and the top of the supporting column 71 is flush with the top of the supporting seat 42. When the lifting seat 31 drives the supporting seat 42 to lift vertically to hold up the material tray 91, the supporting column 71 is in a high position, and the supporting seat 42 and the supporting column 71 support the bottom of the material tray 91 at the same time. As the lifting seat 31 continues to lift, the contact wheel 51 of the lifting seat 31 contacts the side wall of the through groove 231 of the placement seat 23 and rolls. At this time, the contact wheel 51 rolls and drives the supporting seat 42 to swing away relatively, and the contact wheel 51 While rotating, the contact wheel 51 also drives the supporting column 71 to move and descend from a high position to a low position to support the material tray 91, so that when the supporting seat 42 swings and opens, the supporting column 71 gradually supports the material tray 91 to move vertically and descend between the clamping arc grooves 421 of the two supporting seats 42. The supporting column 71 is used to support the material tray 91 to slowly descend into the clamping arc grooves 421 of the supporting seat 42, thereby avoiding the problem of the material tray 91 tilting due to the free fall of the material tray 91, improving the movement stability of the material tray 91 when it descends into a fixed position, and further improving the protection of the material tray 91 during the transportation process.

[0058] As another embodiment provided by the present invention, the driving assembly 5 also includes a driving seat 52 arranged to slide vertically in the lifting seat 31, and a lifting column 72 is arranged to slide horizontally on the driving seat 52. An active cavity 711 is provided in the supporting column 71, and the opening of the active cavity 711 is connected to the top of the supporting column 71. A piston plate 721 is provided on the lifting column 72, and a piston slides in the active cavity 711. The contact wheel 51 is driven to rotate to drive the seat 52 to slide vertically, and the driving seat 52 drives the lifting column 72 to slide vertically synchronously so that the piston plate 721 is first located in the active cavity 711 and then slides, and then the piston plate 721 pushes the supporting column 71 to slide vertically.

[0059] Specifically, such as Figure 6As shown, the driving seat 52 is vertically slidably arranged in the lifting seat 31, and the second sliding portion 724 at the lower end of the lifting column 72 is horizontally slidably arranged in the first sliding groove 521 of the driving seat 52, so that when the sliding seat 41 slides horizontally, the sliding seat 41 can drive the lifting column 72 to slide horizontally relative to the driving seat 52, and the contact wheel 51 can drive the seat 52 to slide vertically when it is driven to rotate. When the lifting seat 31 is vertically lifted to enable the supporting seat 42 to lift the material tray 91, the contact wheel 51 rotates to drive the driving seat 52 to slide vertically downward, and the driving seat 52 drives the lifting column 72 to descend vertically, and the piston plate 721 first The piston in the active chamber 711 slides downward, and at this time the inner volume of the active chamber 711 increases to generate negative pressure, thereby generating suction in the active chamber 711 to adsorb the bottom of the material tray 91, and then the piston plate 721 pushes the supporting column 71 to slide vertically down to drive the supporting column 71 to descend vertically. The supporting column 71 can also adsorb the bottom of the material tray 91 while supporting the bottom of the material tray 91 descends, thereby further improving the stability of the supporting column 71 when it slides vertically against the material tray 91, avoiding the problem of the material tray 91 flipping over and tipping when it descends vertically into the clamping arc groove 421, and improving the transportation stability and safety.

[0060] When the lifting seat 31 descends vertically from the high position to the low position, the sliding seat 41 and the supporting seat 42 support the material tray 91 vertically above the placement seat 23. The contact wheel 51 rotates to cause the driving seat 52 to drive the lifting column 72 to rise vertically. The piston plate 721 first slides upward in the active chamber 711, reducing the volume of the active chamber 711 and generating high pressure. This allows the gas in the active chamber 711 to be sprayed toward the bottom of the material tray 91 to blow away debris or dust on the side of the material tray 91 and the supporting seat 42. Secondly, the flow of gas around the material tray 91 can also reduce the friction between the material tray 91 and the clamping arc groove 421, facilitating the removal of the material tray 91. The supporting seat 42 then swings back to the inside of the lifting seat 31, and the lifting seat 31 continues to descend, causing the supporting seat 42 to descend through the through groove 231, and the material tray 91 is placed back on the placement seat 23.

[0061] The drive assembly 5 further includes a vertical slide 56 and a transmission gear 57. The vertical slide 56 is vertically slidably arranged within the lifting base 31, and the transmission gear 57 is rotatably arranged within the lifting base 31. The contact wheel 51 is provided with a first gear ring portion 511 coupled to a rack provided on the vertical slide 56. The second linear tooth groove 561 of the vertical slide 56 is coupled to the second gear ring portion 571 of the transmission gear 57. The transmission gear 57 is coupled to the first linear tooth groove 523 of the drive base 52. Thus, when the contact wheel 51 rotates, the contact wheel 51 drives the drive base 52 to slide vertically via the vertical slide 56 and the transmission gear 57. This improves the driving stability of the contact wheel 51 on the drive base 52.

[0062] Secondly, a flexible contact ring 73 can be set on the top of the supporting column 71. The existence of the flexible contact ring 73 can improve the protection when contacting the bottom surface of the material tray 91. Secondly, when negative pressure is generated in the active cavity 711, the flexible contact ring 73 can also adaptively deform to improve the adsorption stability of the negative pressure in the active cavity 711 on the material tray 91.

[0063] Another embodiment provided by the present invention further includes an adjustment assembly, which includes a locking rod 61 and an adjustment rod 63. The locking rod 61 is horizontally slidably arranged on the lifting seat 31. The adjustment rod 63 is driven to rotate to drive the locking rod 61 to slide horizontally relative to the vertical projection position of the spectrum probe 111. The lifting column 72 is provided with an interference groove 722. The sliding seat 41 is driven to slide toward the first end of the stroke so that the interference groove 722 interferes with the locking rod 61 and is locked.

[0064] Specifically, such as Figure 11 As shown, the locking rod 61 is horizontally slidably arranged in the movable groove 312 of the lifting seat 31, and when the lifting seat 31 is in the lifted high position, the contact wheel 51 rotates to drive the driving seat 52 and the lifting column 72 to be in the low position. At this time, the interference groove 722 of the lifting column 72 is aligned with the horizontal height of the locking rod 61. When the sliding seat 41 is driven to slide toward the first end of the stroke to move the material tray 91 downward to the spectrum probe 111, the sliding seat 41 drives the lifting column 72 to slide to the interference groove 722 and interfere with the locking rod 61. At this time, the sliding seat 41 slides into place and is locked by the interference of the locking rod 61, thereby achieving the sliding seat 41 being stably located at the lower side of the spectrum probe 111, improving the material tray 91. 1. The stability of the lifting base 31 during inspection by the spectrum probe 111 is ensured to avoid the problem of position displacement of the material tray 91 caused by the sliding of the sliding base 41. Secondly, the lifting column 72 and the driving base 52 are also locked by the locking rod 61 and cannot slide vertically. At this time, the contact wheel 51 is rotated and locked due to the transmission of the driving base 52. At this time, the lifting base 31 can still be driven to perform a certain vertical movement to adjust the vertical distance between the material tray 91 and the spectrum probe 111. The contact wheel 51 is locked and slides against the inner groove 231 of the placement base 23 to improve the sliding stability of the lifting base 31 when vertically adjusting the distance between the material tray 91, reduce the horizontal jitter of the lifting base 31 and the material tray 91, and facilitate the vertical distance adjustment of the material tray 91.

[0065] Secondly, the adjusting rod 63 can be rotated to drive the locking rod 61 to move horizontally relative to the lifting seat 31. Since the sliding seat 41 moves to the first end of the sliding stroke until the lifting column 72 contacts the locking rod 61 and is locked, the adjusting rod 63 and the locking rod 61 can be used to adjust the horizontal stop position of the sliding seat 41 and its loading tray 91, so as to facilitate the vertical alignment of the loading tray 91 of the sliding seat 41 and the spectral probe 111, thereby improving the inspection range and accuracy of the tray 91.

[0066] Furthermore, a driving rod 64 is symmetrically rotatably arranged in the lifting seat 31, and a threaded column portion 641 is provided on the driving rod 64 for threaded cooperation with the locking rod 61, and a worm portion 631 is provided on the adjusting rod 63, and the worm portion 631 is coupled with the worm wheel portion 642 provided on the driving rod 64, so that the adjusting rod 63 can be used to drive the driving rod 64 to rotate to achieve horizontal position adjustment of the locking rod 61, and the worm portion 631 and the worm wheel portion 642 are used for transmission to achieve self-locking of the locking rod 61, thereby avoiding the problem of vertical position deviation of the sliding seat 41, the material tray 91 and the spectral probe 111 caused by accidental movement of the locking rod 61, thereby improving the alignment accuracy of the material tray 91 and the spectral probe 111.

[0067] Furthermore, a lap hook 723 is provided on the lifting column 72. When the lifting column 72 slides to the contact groove 722 and contacts the locking rod 61, the lap hook 723 is connected to the locking rod 61 to further improve the locking stability between the locking rod 61 and the lifting column 72, thereby improving the inspection stability of the material tray 91.

[0068] After the inspection is completed, the sliding seat 41 slides to the second end of the sliding stroke. At this time, the sliding seat 41 drives the lifting column 72 to slide away from the locking rod 61. The overlapping hook 723 squeezes the lower end of the locking rod 61 so that the lifting column 72 also slides vertically downward at the moment of starting horizontal sliding, thereby generating negative pressure in the active cavity 711 of the supporting column 71 to adsorb the bottom of the material tray 91. When the overlapping hook 723 is completely disengaged, the lifting column 72 rises vertically to eliminate the negative pressure in the active cavity 711. As a result, when the sliding seat 41 drives the material tray 91 to move away from the spectral probe 111, the supporting column 71 can generate an instantaneous adsorption and fixing negative pressure on the material tray 91, thereby preventing the material tray 91 from flying out of the lifting seat 31 under the action of acceleration, and further improving the conveying stability of the material tray 91.

[0069] As another embodiment provided by the present invention, a stabilizing wheel 62 is symmetrically rotatably arranged on the locking rod 61, and an entry groove 425 is opened on the bottom surface of the supporting seat 42. The sliding seat 41 is driven to slide toward the first end of the stroke so that the stabilizing wheel 62 rolls and rests in the entry groove 425.

[0070] Specifically, such as Figure 3As shown, stabilizing wheels 62 are symmetrically provided on the locking rod 61, and the stabilizing wheels 62 are located on both horizontal sides of the lifting seat 31. When the sliding seat 41 is driven to slide toward the first end of the stroke to drive the material tray 91 to move toward the spectrum probe 111, the sliding seat 41 drives the supporting seat 42 to move close to the stabilizing wheel 62 so that the top of the stabilizing wheel 62 rolls into and is supported in the entry groove 425. At this time, the stabilizing wheel 62 rolls and supports the bottom surface of the supporting seat 42, thereby improving the parallelism of the supporting seat 42 with the horizontal plane when it moves close to the bottom of the spectrum probe 111, thereby improving the levelness of the material tray 91 inside the clamping arc groove 421 of the supporting seat 42, reducing the tilt of the material tray 91, and improving the inspection accuracy of the developer in the material tray 91 by the spectrum probe 111.

[0071] Secondly, a moving groove 112 is opened on the detection part 11 of the base 1. When the lifting base 31 is driven to move up and down, the stabilizing wheel 62 moves in the moving groove 112 to avoid the problem of movement interference.

[0072] As another embodiment provided by the present invention, both supporting seats 42 are provided with rubber blocks 92 that are spliced ​​with the clamping arc groove 421 to form an arc-shaped clamping surface, and a hollow cavity 921 is opened inside the rubber block 92 on one of the supporting seats 42, and an elastic plate 93 with an obtuse angle is provided in the hollow cavity 921, and an arched portion 4251 extending into the entry groove 425 is provided on the supporting seat 42, and the arched portion 4251 is facing away from the clamping arc groove 421.

[0073] Specifically, such as Figure 3 As shown, a rubber block 92 is provided on the supporting seat 42, and the rubber block 92 is spliced ​​with the clamping arc groove 421 to form an arc-shaped clamping surface, and the rubber block 92 is located on the side of the clamping arc groove 421 away from the rotating shaft of the supporting seat 42. When the two supporting seats 42 swing relatively away from each other so that the clamping arc groove 421 clamps the circumference of the material tray 91, the presence of the rubber block 92 can increase the friction between the supporting seat 42 and the material tray 91, thereby further improving the clamping and fixing stability of the supporting seat 42 to the material tray 91. Secondly, the rubber block 92 can be adaptively deformed to avoid damage to the material tray 91 caused by the supporting seat 42.

[0074] The material tray 91 contains developer, and the upper part of the material tray 91 is a transparent shielding cover. During the transportation of the material tray 91, the developer will inevitably shake, causing a number of droplets to stick to the inner wall of the top of the material tray 91. If the spectrum probe 111 and the material tray 91 are inspected, the droplets on the inner wall of the top of the material tray 91 will cause relatively random and unexpected refraction of the inspection light emitted by the spectrum probe 111, thereby causing errors in the inspection data of the developer in the material tray 91.

[0075] The support seat 42 is also provided with an arched portion 4251. When the sliding seat 41 drives the support seat 42 and the material tray 91 to move closer to the side of the spectrum probe 111, the support seat 42 moves closer to the stabilizing wheel 62 and the Shudie stabilizing wheel 62 gradually rolls and extends into the groove 425. The stabilizing wheel 62 is squeezed by the arched portion 4251 and exerts a relative swinging pressure on the support seat 42, and the material tray 91 is located in the clamping arc groove 421 and is squeezed by the pressure of the support seat 42. There are two rubber blocks 92. Since one rubber block 92 is solid and the other rubber block 92 has a hollow cavity 921 and an elastic plate 93, and the solid rubber block 92 can be deformed to a small extent, the material tray 91 will gradually squeeze the elastic plate 93 to deform and accumulate energy until the elastic plate 93 is deformed to a straight line. At this time, the elastic plate 93 is bent toward the inside of the hollow cavity 921 by the pressure of the material tray 91, and the material tray 91 also squeezes the hollow cavity 921 to deform and shrink, that is, Figure 7 As shown, the pressure on the side of the tray 91 near the elastic plate 93 suddenly decreases due to the deformation of the elastic plate 93, causing the tray 91 to suddenly rotate axially under the squeezing force of the support seat 42. As a result, the droplets on the top inner wall of the tray 91 slide toward the surrounding side walls under the action of the rotating centrifugal force, eliminating the droplets from adhering to the top inner wall of the tray 91, thereby improving the accuracy of the spectrometer probe 111 in detecting the developer in the tray 91.

[0076] Secondly, when the bottom of the supporting material tray 91 descends, the supporting column 71 adsorbs the bottom of the material tray 91 through the negative pressure in the active cavity 711. When the material tray 91 suddenly rotates axially under the squeezing force of the supporting seat 42, a gap is generated between the material tray 91 and the supporting column 71, and the negative pressure in the active cavity 711 disappears. At this time, the active cavity 711 of the supporting column 71 no longer generates suction on the bottom of the material tray 91, thereby avoiding the problem of the material tray 91 being deformed and concave due to the adsorption force for a long time, thereby further improving the protection of the material tray 91 and the detection stability.

[0077] As another embodiment provided by the present invention, the driving assembly 5 also includes a movable column 53, a rotating wheel 54 and a synchronous belt 55. The first end of the movable column 53 is horizontally slidably arranged on the driving seat 52, and the rotating wheel 54 is rotatably arranged in the sliding seat 41. A spiral-shaped push portion 531 is provided on the side surface of the movable column 53. The push portion 531 is slidably arranged in a matching groove 541 opened on the rotating wheel 54. The driving seat 52 drives the movable column 53 to move vertically to push the rotating wheel 54 to rotate, and the rotating wheel 54 rotates synchronously with the rotating portion 422 of the supporting seat 42 through the synchronous belt 55.

[0078] Specifically, such as Figure 9As shown, the first sliding portion 532 of the movable column 53 is horizontally slidably arranged in the second sliding groove 522 of the driving seat 52, the rotating wheel 54 is rotatably arranged in the sliding seat 41, and the rotating portion 422 of the supporting seat 42 is rotatably arranged on the sliding seat 41, and the synchronous belt 55 is sleeved on the rotating wheel 54 and the connecting portion 424 provided on the rotating portion 422. When the lifting seat 31 is vertically lifted to rotate the contact wheel 51, the contact wheel 51 drives the driving seat 52 to move vertically downward, and the driving seat 52 drives the movable column 53 to move vertically downward, and the movable column 53 drives the rotating wheel 54 to rotate through the pushing portion 531 and the matching groove 541, and the rotating wheel 54 drives the supporting seat 42 to swing relatively away through the synchronous belt 55. The movable column 53, the rotating wheel 54 and the synchronous belt 55 are used to realize the driving of the supporting seat 42 by the contact wheel 51, thereby improving the driving stability of the supporting seat 42.

[0079] Secondly, a synchronous ring gear 423 is provided on the rotating portion 422 of the supporting seat 42 . The synchronous ring gears 423 of the two supporting seats 42 are coupled to each other to improve the stability of the supporting seats 42 when they swing relative to each other.

[0080] As another embodiment provided by the present invention, the supporting column 71 is vertically movably arranged in the sliding seat 41 through the sliding ring portion 712, and the sliding ring portion 712 is provided with inner grooves 713 in a symmetrical circular array. The movable column 53 slides vertically so that the pushing portion 531 moves to push the inner groove 713 to enable the supporting column 71 to rotate axially.

[0081] Specifically, such as Figure 10 As shown, the supporting column 71 is vertically movable in the sliding seat 41 through the sliding ring portion 712, and the sliding ring portion 712 is provided with inner grooves 713 in a symmetrical circumferential array, as shown in FIG. Figure 12 When the lifting seat 31 is lifted vertically, the contact wheel 51 rotates to make the driving seat 52 drive the movable column 53 and the lifting column 72 move vertically downward. At this time, the support column 71 has not yet produced vertical movement, and the movable column 53 moves vertically to make the pushing portion 531 move to push the inner groove 713 of the support column 71, thereby driving the support column 71 to produce axial rotation, so that the support column 71 can drive the material tray 91 located on the top surface of the support seat 42 to perform a certain axial rotation, reducing the friction between the bottom of the material tray 91 and the top of the support seat 42, making it easier for the support seat 42 to swing relatively away. At this time, because the movable column 53 is in contact with the support column 71, the support column 71 will not rotate randomly due to the friction of the material tray 91 against the support seat 42, thereby further improving the supporting stability of the support column 71 on the material tray 91;

[0082] Afterwards, as the drive seat 52 continues to descend vertically, the movable column 53 separates from the supporting column 71, and the lifting column 72 drives the supporting column 71 to descend vertically so that the material tray 91 enters between the supporting seats 42. During this process, the supporting column 71 can rotate freely axially to facilitate the material tray 91 to enter the clamping arc groove 421.

[0083] When the lifting seat 31 descends vertically, the contact wheel 51 rotates to make the driving seat 52 drive the movable column 53 and the lifting column 72 to move vertically upward. At this time, the supporting column 71 is in the low position and has not yet moved vertically. The movable column 53 moves vertically upward so that the pushing portion 531 can move to push the inner groove 713 of the supporting column 71, thereby driving the supporting column 71 to rotate axially, so that the supporting column 71 can drive the material tray 91 located in the clamping arc groove 421 of the supporting seat 42 to perform a certain axial rotation, thereby reducing the friction between the material tray 91 and the clamping arc groove 421, and facilitating the vertical lifting and separation of the material tray 91;

[0084] Afterwards, as the drive seat 52 continues to rise vertically, since the movable column 53 is in contact with the supporting column 71, the supporting column 71 will not rotate randomly due to the friction of the material tray 91 by the supporting seat 42, thereby further improving the stability of the supporting column 71 when lifting the material tray 91 away from the clamping arc groove 421.

[0085] Working principle:

[0086] S1. First, pour equal amounts of different developer solutions into a plurality of trays 91, close the lids of the trays 91, and then place the trays 91 on different placement seats 23;

[0087] S2, the driving moving belt 22 stops after aligning a certain placement seat 23 with the lifting seat 31, and the lifting seat 31 drives the supporting seat 42 to lift vertically to pass through the through slot 231. The supporting seat 42 rises to lift the material tray 91 on the placement seat 23, and as the lifting seat 31 continues to lift, the contact wheel 51 rolls against the side wall of the through slot 231 to make the supporting seat 42 swing away relatively, and the contact wheel 51 also drives the lifting column 72 to descend through the driving seat 52. At this time, the top of the supporting column 71 generates suction to adsorb the material tray 91, and then the supporting column 71 descends vertically to support the material tray 91 and enter the clamping arc slot 421;

[0088] S3, the sliding seat 41 drives the supporting seat 42 and the material tray 91 to move horizontally toward the vertical lower side of the spectrum probe 111, and the supporting seat 42 approaches the stabilizing wheel 62 so that the stabilizing wheel 62 rolls and rests in the entry groove 425. The arched portion 4251 of the entry groove 425 squeezes the stabilizing wheel 62 so that the supporting seat 42 swings closer due to the reaction force to clamp the peripheral side of the material tray 91. The material tray 91 is squeezed by the supporting seat 42 to apply pressure to the rubber block 92. The elastic plate 93 inside the rubber block 92 stores energy and then releases its deformation to make the material tray 91 rotate rapidly axially, thereby throwing the droplets on the top wall of the material tray 91 to the peripheral side.

[0089] S4, until the sliding seat 41 slides until the lifting column 72 thereon contacts the locking rod 61, the sliding seat 41 stops sliding, and at this time, the material tray 91 and the spectrum probe 111 are vertically aligned;

[0090] S5. The developer in the material tray 91 is inspected by the spectral probe 111. After the inspection is completed, the sliding seat 41 slides back to move the material tray 91 closer to the placement seat 23. Then, the lifting seat 31 descends vertically to drive the supporting column 71 via the contact wheel 51 and the driving seat 52 to lift the material tray 91. The supporting seat 42 swings relatively close to reset. Then, the inspected material tray 91 falls on the placement seat 23, and the lifting seat 31 descends to the low position.

[0091] S6. Repeat steps S2-S5 to inspect the developer inside the material tray 91 placed on each placement seat 23.

[0092] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
