Description

Technical Field

[0001] The present invention relates to the field of light inspection machine equipment, and in particular to a main shaft tracking transmission mechanism of a turntable supporting and pressing light inspection machine. Background Art

[0002] Light inspection machines are generally equipment used to perform light inspections on products, and are generally used to inspect bottle-type products, such as infusion bottles, ampoules and other products. The turntable support and pressure light inspection machine lifts the bottom of the inspected product through the base, and presses down the top of the product with a pressure head, so that the product is "supported and pressed" and fixed, and then transported along the conveying channel of the corresponding turntable, and inspected during the transportation process. The turntable support and pressure light inspection machine is mainly used for light inspection of slender products with small bottle diameters and long lengths, such as ampoules, oral liquid bottles and other products; because these products are relatively slender, if they are only clamped from the bottom or head of the product, it is often impossible to ensure that the product clamping posture is uniform, and it is easy to cause clamping deviation. Therefore, in order to ensure the clamping accuracy of the product, a support and pressure light inspection machine is required for clamping and light inspection.

[0003] However, when capturing images, the inspection machine requires a camera or other image capture device, as well as a backlight source to illuminate the product. Since a turntable-supported inspection machine needs to contact the product from both the top and bottom ends, its turntable is actually equipped with an upper and lower rotating disc structure. A light inspection conveyor channel is formed between the outer edges of the upper and lower rotating discs. The inspected product moves along the light inspection conveyor channel, and one of the corresponding backlight source and camera is located inside the area enclosed by the light inspection conveyor channel, while the other needs to be located outside. Since the backlight source and camera often need to track the inspected product for a certain distance in synchronization, they are required to remain synchronized during movement, that is, maintain the same angular velocity. The traditional processing method is to set the camera tracking disk and the backlight tracking disk to be fixedly connected as one body, and to achieve a fixed connection after bypassing the upper or lower turntable by setting a corresponding interlayer shaft sleeve on the main shaft, and then to directly drive the camera tracking disk and the backlight tracking disk to track and move by setting a driving mechanism; however, this structure will lead to a complex structural relationship of the main shaft part, and usually it is necessary to set up three or more layers of shafts or shaft sleeve structures that can rotate relative to each other. At the same time, the shaft sleeve also needs to pass through the connection structure between the upper or lower turntable and the main shaft, and the processing and assembly are also very cumbersome, and it will also increase the equipment cost and the difficulty of subsequent maintenance. Summary of the Invention

[0004] The technical problem solved by the present invention is to provide a main shaft tracking transmission mechanism of a turntable supporting and pressing type light inspection machine with a simple transmission mechanism.

[0005] The present invention solves the technical problem by adopting the following technical solution: a spindle tracking drive mechanism for a turntable support-type optical inspection machine, comprising a mounting platform, a spindle sleeve, a spindle, a spindle drive mechanism, an upper rotating disk, a lower rotating disk, a first tracking disk, and a second tracking disk. The spindle sleeve is fixed to the mounting platform, the spindle is rotatably mounted in the spindle sleeve, the upper rotating disk and the lower rotating disk are respectively fixedly mounted on the spindle, a light inspection conveying channel is formed between the outer peripheral edges of the upper rotating disk and the lower rotating disk, the spindle drive mechanism is connected to the spindle for driving the spindle to rotate, and further comprises a first tracking drive mechanism and a second tracking drive mechanism. The first tracking disk is arranged outside the light inspection conveying channel between the upper rotating disk and the lower rotating disk, and the second tracking disk is arranged inside the light inspection conveying channel between the upper rotating disk and the lower rotating disk. The first tracking drive mechanism is connected to the first tracking disk for driving the first tracking disk to reciprocate, and the second tracking drive mechanism is connected to the second tracking disk for driving the second tracking disk to reciprocate, and the first tracking drive mechanism and the second tracking drive mechanism are synchronously controlled to synchronize the reciprocating oscillation of the first tracking disk with the reciprocating oscillation of the second tracking disk.

[0006] Furthermore, the first tracking drive mechanism and the second tracking drive mechanism are both servo motors.

[0007] Furthermore, the first tracking drive mechanism is fixedly connected to the main shaft sleeve through a first mounting plate; the first tracking disk is rotatably mounted on the main shaft sleeve through a first bearing, and a first driven rack is provided on the first tracking disk, and the first driven rack is engaged with the first driving wheel on the first tracking drive mechanism for transmission.

[0008] Furthermore, it also includes a mounting bracket, one end of which extends between the upper turntable and the lower turntable and is connected through a first sleeve movably sleeved on the main shaft, and the other end of the mounting bracket extends from the gap between the outer peripheral edges of the upper turntable and the lower turntable to form a light inspection conveying channel and is fixedly mounted on the mounting platform through a mounting column, and the second tracking drive mechanism is fixedly mounted on the mounting bracket; the second tracking disk is rotatably sleeved on the main shaft through a second bearing, and a second driven rack is provided on the second tracking disk, and the second driven rack is engaged with the second driving wheel on the second tracking drive mechanism for transmission.

[0009] Furthermore, the second tracking disk includes a second shaft sleeve, and the second shaft sleeve is rotatably sleeved on the main shaft through a second bearing.

[0010] Furthermore, the first sleeve is rotatably mounted on the main shaft via a third bearing.

[0011] Furthermore, a bearing group is provided between the main shaft sleeve and the main shaft, and the bearing group includes a first roller bearing provided at the upper end of the main shaft sleeve and a first ball bearing provided at the upper end of the main shaft sleeve.

[0012] Furthermore, the main shaft driving mechanism is fixedly connected to the main shaft sleeve via the second mounting plate, and the third driving wheel on the main shaft driving mechanism is meshed with the driven gear provided on the main shaft for transmission.

[0013] The present invention has the following beneficial effects: by separately providing corresponding first and second tracking drive mechanisms for the first and second tracking disks, the first and second tracking disks do not need to be fixedly connected in structure, thereby resolving the inconvenience of fixedly connecting the first and second tracking disks due to the coexistence of an upper and lower rotating disks in a turntable-supported light inspection machine. Furthermore, to achieve synchronization between the first and second tracking disks, the present invention utilizes synchronously controlled first and second tracking drive mechanisms, utilizing electrical control technology for the tracking drive mechanisms to achieve synchronous drive. As a result, compared to conventional structures requiring an interlayer sleeve mounted on the main shaft, the present invention simplifies the structure of the main shaft, facilitates processing and assembly, and reduces equipment costs and subsequent maintenance difficulties.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] It should be noted that any directional terms used in this disclosure, such as "up," "down," "left," "right," "front," and "back," are intended to facilitate descriptions of the relative positions of components and are not intended to specify the absolute positions of related components or the positional relationships between them. They are intended only to explain the relative positions and motion of components in a specific posture. If the posture changes, the directional terms will also change accordingly.

[0023] like Figures 1 to 6 As shown in the figure, the spindle tracking transmission mechanism of the turntable support and pressure type light inspection machine of the present invention includes a mounting platform 1, a spindle sleeve 2, a spindle 3, a spindle driving mechanism 4, an upper rotary disc 5, a lower rotary disc 6, a first tracking disc 7 and a second tracking disc 8. The spindle sleeve 2 is fixed on the mounting platform 1, and the spindle 3 can be rotatably mounted in the spindle sleeve 2. The upper rotary disc 5 and the lower rotary disc 6 are respectively fixedly mounted on the spindle 3. A light inspection conveying channel is formed between the outer peripheral edges of the upper rotary disc 5 and the lower rotary disc 6. The spindle driving mechanism 4 is connected to the spindle 3 to drive the spindle 3 to rotate; and then drives the upper rotary disc 5 and the lower rotary disc 6 to rotate synchronously with the spindle 3. The upper rotary disc 5 is used to install the pressure head structure for pressing down from the top of the bottle body to be inspected, and the lower rotary disc 6 is used to install the corresponding base for lifting. As shown in the accompanying drawings, the product to be inspected, such as an ampoule product, is input from the feed conveyor line 29, passed through the feed screw and the feed star wheel 30, and then handed over to the lower rotary disk 6 between the upper rotary disk 5. After being clamped by the pressure head and the base on the upper rotary disk 5 and the lower rotary disk 6, it rotates with the upper rotary disk 5 and the lower rotary disk 6 and is transported along the light inspection conveying channel between the outer peripheral edge of the upper rotary disk 5 and the lower rotary disk 6. Corresponding image collection and inspection are performed during the transportation process, and then it is output to the corresponding discharge conveyor line 32 through the discharge star wheel 31 and then discharged.

[0024] The first tracking disk 7 and the second tracking disk 8 serve as the mechanism for mounting the camera 33 and backlight 34 required for image acquisition and achieving synchronous tracking. The camera 33 and backlight 34 can theoretically be mounted on the first tracking disk 7 and the second tracking disk 8, respectively. As shown in the accompanying drawings, the camera 33 is mounted on the first tracking disk 7, while the backlight 34 is mounted on the second tracking disk 8. Furthermore, depending on the product location and the inspection object, multiple groups of image acquisition devices can theoretically be installed along the conveying direction of the inspection conveyor channel, each group containing a corresponding camera 33 and backlight 34. Of course, all cameras 33 in all groups can be mounted on the first tracking disk 7, and all backlights 34 in all groups can be mounted on the second tracking disk 8.

[0025] The present invention specifically includes a first tracking drive mechanism 9 and a second tracking drive mechanism 10. The first tracking disk 7 is arranged outside the light detection conveying channel between the upper rotating disk 5 and the lower rotating disk 6, and the second tracking disk 8 is arranged inside the light detection conveying channel between the upper rotating disk 5 and the lower rotating disk 6. The first tracking drive mechanism 9 is connected to the first tracking disk 7 in a transmission manner to drive the first tracking disk 7 to swing back and forth. The second tracking drive mechanism 10 is connected to the second tracking disk 8 in a transmission manner to drive the second tracking disk 8 to swing back and forth. The first tracking drive mechanism 9 and the second tracking drive mechanism 10 are synchronously controlled to synchronize the reciprocating swing of the first tracking disk 7 with the reciprocating swing of the second tracking disk 8. Through the above-described configuration, the present invention provides separate first tracking drive mechanisms 9 and second tracking drive mechanisms 10 for the first tracking disk 7 and the second tracking disk 8, eliminating the need for a fixed structural connection between the first tracking disk 7 and the second tracking disk 8. This eliminates the problem of the inconvenience of fixed connection between the first tracking disk 7 and the second tracking disk 8 due to the coexistence of the upper rotating disk 5 and the lower rotating disk 6 in the turntable support type light inspection machine. Furthermore, to achieve synchronization between the first tracking disk 7 and the second tracking disk 8, synchronous control of the first tracking drive mechanism 9 and the second tracking drive mechanism 10 is employed, utilizing electrical control technology for the tracking drive mechanism to achieve synchronous drive. Specifically, for example, by configuring both the first tracking drive mechanism 9 and the second tracking drive mechanism 10 as servo motors, the two servo motors can be synchronously driven and controlled by their control systems, thereby achieving precise synchronous control of the first tracking drive mechanism 9 and the second tracking drive mechanism 10, ensuring synchronous drive of the two, and thereby ensuring synchronous tracking of the camera 33 and the backlight source 34. Therefore, compared with the traditional structure that requires an interlayer sleeve to be set on the main shaft 3, the present invention can make the structural relationship of the main shaft part simpler, and is more convenient to process and assemble, which can reduce equipment costs and the difficulty of subsequent maintenance.

[0026] More specifically, as shown in the accompanying drawings, the present invention further comprises a first tracking drive mechanism 9 fixedly connected to the spindle sleeve 2 via a first mounting plate 11; a first tracking disk 7 is rotatably mounted on the spindle sleeve 2 via a first bearing 13; a first driven rack 16 is provided on the first tracking disk 7, and the first driven rack 16 engages with a first driving wheel 17 on the first tracking drive mechanism 9 for transmission. This greatly simplifies the installation of the first tracking drive mechanism 9, allowing it to be directly mounted on the spindle sleeve 2; and the installation of the first tracking disk 7 is also very simple, allowing it to be directly mounted on the spindle sleeve 2 via the first bearing 13.

[0027] More specifically, in order to facilitate the installation of the second tracking drive mechanism 10, the present invention further includes a mounting bracket 18, one end of the mounting bracket 18 extends between the upper turntable 5 and the lower turntable 6 and is connected through a first shaft sleeve 19 movably sleeved on the main shaft 3, and the other end of the mounting bracket 18 extends from the gap 20 between the outer peripheral edges of the upper turntable 5 and the lower turntable 6 to form a light inspection conveying channel and is fixedly mounted on the mounting platform 1 through a mounting column 21, and the second tracking drive mechanism 10 is fixedly mounted on the mounting bracket 18; the second tracking disk 8 is rotatably sleeved on the main shaft 3 through a second bearing 14, and a second driven rack 22 is provided on the second tracking disk 8, and the second driven rack 22 is engaged with the second driving wheel 23 on the second tracking drive mechanism 10 for transmission. The gap opening 20 is located between the feed star wheel 30 and the discharge star wheel 31 as shown in the accompanying drawings. Since there is no product to be detected between the pressure head and the base at this position, a gap opening 20 with a relatively small angle is formed between the upper turntable 5 and the lower turntable 6 at this position. In the present invention, the gap opening 20 is used to extend the mounting bracket 18 into the inner area of the upper turntable 5 and the lower turntable 6 to serve as a bearing base for fixing the second tracking drive mechanism 10. At the same time, the mounting bracket 18 is fixedly installed on the mounting platform 1 through the mounting column 21, and the first sleeve 19 can further support the end portion of the mounting bracket 18. Of course, in order to ensure the relative rotational fit between the first sleeve 19 and the main shaft 3, the first sleeve 19 can be further arranged to be rotatably mounted on the main shaft 3 through the third bearing 15.

[0028] More specifically, to ensure relative rotational cooperation between the second tracking disk 8 and the main shaft 3 , the second tracking disk 8 may include a second sleeve 24 , which is rotatably mounted on the main shaft 3 via a second bearing 14 .

[0029] More specifically, to ensure relative rotational fit between the main shaft sleeve 2 and the main shaft 3 and to provide axial support for the main shaft 3 through the main shaft sleeve 2, a bearing assembly is further provided between the main shaft sleeve 2 and the main shaft 3. The bearing assembly includes a first roller bearing 25 provided at the upper end of the main shaft sleeve 2 and a first ball bearing 26 provided at the lower end of the main shaft sleeve 2. The first roller bearing 25 is provided at the upper end and provides strong axial support for the bearing 3 by utilizing its good axial load-bearing capacity.

[0030] More specifically, in the present invention, the transmission structure of the spindle drive mechanism 4 can be further configured such that the spindle drive mechanism 4 is fixedly connected to the spindle sleeve 2 through the second mounting plate 12, and the third driving wheel 27 on the spindle drive mechanism 4 is engaged with the driven gear 28 provided on the spindle 3 for transmission.

[0031] The spindle drive mechanism 4, the first tracking drive mechanism 9 and the second tracking drive mechanism 10 in the present invention all adopt the meshing structure between gears or the meshing structure between gears and racks for transmission, which can ensure high transmission accuracy to ensure the accuracy requirements of synchronous tracking.
