[0002] Test card products made of lightweight materials, such as rapid virus screening test cards, require multiple processes on the production line. In the past, workers had to place the card workpieces or semi-finished products onto the conveyor line, and the cards were transported by the conveyor mechanism. The workpieces were sorted by filtering mechanisms, but manual intervention was often required to correct the transport or arrangement of the workpieces before inkjet printing. Several corresponding processes were required in succession during this process. Many old production lines processed batches of test card workpieces at different workstations before moving to the next workstation, so they could not achieve continuous and fast inkjet printing production, resulting in low efficiency.

[0031] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0032] In the description of this invention, it should be understood that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" used in this invention should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] In the description of this invention, it should also be understood that the terms "upper", "lower", "left", "right", "front", "rear", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the machine or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] refer to Figure 1 -11. A test card multi-channel inkjet printing production line according to an embodiment of the present invention includes a feeding belt line 1, a diversion belt line 2 and a belt conveyor line 5 arranged in sequence.

[0035] Both the feeding conveyor belt 1 and the diversion conveyor belt 2 are provided with a number of corresponding dividing channels. The output end of the dividing channel on the feeding conveyor belt 1 is correspondingly close to the input end of the dividing channel on the diversion conveyor belt 2. The diversion conveyor belt 2 is also provided with a material collection sensor 21, a channel gate 22, and a guide rail 23. There are several material collection sensors 21 and several channel gates 22. The material collection sensors 21 and several channel gates 22 are located on each dividing channel. The material collection sensors 21 are in front of the channel gates 22 along the feeding direction of the diversion conveyor belt 2. The guide rails 23 are located behind the output end of the dividing channel on the diversion conveyor belt 2. There are two guide rails 23 arranged in a V-shape. The wide ends of the two guide rails 23 face the output end of the dividing channel on the diversion conveyor belt 2.

[0036] The narrow ends of the two guide rails 23 are located at or near the rear end of the diversion belt 2. This multi-channel test card conveyor can cooperate with other automated equipment on the production line. During loading, a robotic arm or robot precisely places the test card workpieces into the corresponding compartments of the loading belt 1. Each compartment can simultaneously hold one or more test card workpieces. The loading belt 2 carries the workpieces to the end of the compartments and transfers them from the loading belt 1 to the diversion belt 2, where they enter the corresponding compartments for further transport and pass through the collection sensor 21. The collection sensor 21 on each compartment detects the number of workpieces passing through. When a set number is reached, a signal is sent to the control device or main control module to control the channel gate 22, or the signal is sent directly to the channel gate 22. The channel gate 22 opens from the default position of blocking workpieces in the compartment, allowing the workpieces to continue to be transported to the guide rails 23. The workpieces are limited by the guide rails 23 on either side and output through the narrow end, thus outputting the test card. At the next stage of the production line, the workpieces in each separated channel are controlled by the material collection sensor 21 and the channel gate 22. This allows the workpieces fed by the feeding belt 1 in one go or continuously to be diverted and transported in an efficient manner. They are then orderly collected by the guide rail 23 and gathered at the subsequent workstations, eliminating the need for manual handling. The feeding belt 1 is adapted to allow automated equipment such as robotic arms and robots to place workpieces in the separated channels according to the settings. The workpieces are reasonably accommodated and synchronously transported to the diversion belt 2. Then, the workpieces are automatically collected in the separated channels according to the settings and released one by one. This allows any number of workpieces to be transported through any number of separated channels, which greatly solves the problem of workpiece blockage. The transportation is smooth and efficient. This is well-suited to the characteristics of the test card, which is lightweight and small in size. The material collection sensor 21 can be a commonly used infrared, laser, photoelectric, or mechanical sensor. The channel gate 22 can be electrically driven, pneumatically driven, or hydraulically driven.

[0037] The belt conveyor line 5 is equipped with a plasma treatment device 61, a color mark trigger 62, a coding device 63, a UV curing unit 64, and a visual recognition device 65, arranged from front to back. Between the plasma treatment device 61 and the color mark trigger 62, a set of guide vanes 51 and a set of guide rails 52 are arranged one in front of the other on the belt conveyor line 5. The set of guide vanes 51 consists of two symmetrical pieces forming a flared shape that narrows from front to back. The set of guide rails 52 consists of two parallel pieces distributed side-by-side. Test card workpieces are transferred one by one onto the belt conveyor line 5. The test cards and other workpieces first undergo surface treatment in the plasma treatment device 65, and then... After being guided by the guide plate 51 and the guide rail 52, the workpiece moves to the color mark trigger 62, thereby triggering the inkjet printer 63 to print the workpiece. The ink is then rapidly cured by the UV lamp of the UV curing unit 64. Finally, the workpiece is inspected by the vision recognition device 65. If a defective product is found, a signal is sent to the subsequent mechanism for corresponding processing. For example, the defective product can be moved to a specific recycling area via a subsequent reroutable conveyor line. These are all conventional methods in the prior art. The plasma processing device 61, the color mark trigger 62, the inkjet printer 63, the UV curing unit 64, and the vision recognition device 65 are all existing devices that can be flexibly selected.

[0038] Therefore, the test card workpiece is fed by a robotic arm or robot, and first transferred to the sorting belt 2 through the feeding belt 1 for sorting and converging, so that it enters the belt conveyor 5 in an orderly and continuous manner for the inkjet printing process. The efficiency is very high, the degree of automation is extremely high, and it is very convenient.

[0039] refer to Figure 2 , 4 Alternatively, as an example, a diversion release sensor 24 is further provided on the diversion conveyor 2 between the material collection sensor 21 and the channel gate 22. Several diversion release sensors 24 are present and located correspondingly on each dividing channel, and preferably close to the channel gate 22. The diversion release sensor 24 can be a sensor with the same structure as the material collection sensor 21, which monitors the status of the workpieces in each dividing channel near the channel gate 22 in real time. When the channel gate 22 is set to release workpieces in turn through each dividing channel, Based on the detection of the diversion and release sensor 24, after the workpiece in front of the channel gate 22 of the same newly started separation channel has been instantly sent out, a corresponding signal is randomly sent to close the channel gate 22 and start the next channel gate 22. This cycle is repeated to ensure that the actual workpiece can be monitored in each separation channel to control the channel gate 22. This eliminates the need to control the channel gate 22 by calculating the conveyor belt speed to set the corresponding opening time. Moreover, it can work in conjunction with the material collection sensor 21 to simultaneously detect the workpiece status in each separation channel, making the automated operation more complete.

[0040] refer to Figure 2 Alternatively, 5, for example, the diversion belt 2 is further provided with a full material sensor 25 in front of the material collection sensor 21 along the feeding direction. There are several full material sensors 25, which are respectively located on each dividing channel. The full material sensor 25 can be a sensor with the same structure as the material collection sensor 21. The full material sensor 25 is preferably set in the middle of the diversion belt 2, so as to detect in real time whether the workpieces in the dividing channel have accumulated to the corresponding full material condition, so as to send a signal to open the corresponding channel gate 22 to transport the workpiece in time, thereby avoiding the overload and blockage caused by the workpieces piling up after the dividing channel is full.

[0041] refer to Figure 2 Alternatively, as an example, the diversion conveyor belt 2 is also provided with several height limiting rods 26, each of which is located on each dividing channel. The height limiting rods 26 are perpendicular to the surface of the diversion conveyor belt 2 from top to bottom. When the workpiece moves from the diversion conveyor belt 2 over a longer distance through the dividing channel, the height limiting rods 26 can prevent the lighter test card workpiece from leaving the dividing channel from the top, thereby avoiding transport errors and ensuring that the test card workpiece moves quickly and stably.

[0042] refer to Figure 9 Alternatively, 10, for example, the diversion conveyor 2 is also provided with several blockage sensors 27. Each blockage sensor 27 is located on the dividing channel near the front end. The blockage sensor 27 can be a sensor with the same structure as the collecting sensor 21. The blockage sensor 27 is mainly used for shorter conveyor belts. When the workpiece is transported at a high speed or due to mechanical reasons, a blockage occurs in the dividing channel near the front end of the diversion conveyor 2. The blockage sensor 27 sends a signal to the control device, alarm, etc., so that maintenance personnel can inspect or handle it in time.

[0043] refer to Figure 2 and 3 For example, each of the dividing channels on the diversion belt 2 is provided with two guide vanes 42 at its front end. Each pair of guide vanes 42 forms a flared opening and faces the dividing channel on the feeding belt 1. When the test card workpiece is sent from the dividing channel of the feeding belt 1 to the diversion belt 2, the workpiece passes through the flared opening formed by the corresponding two guide vanes 42 before entering the corresponding dividing channel. The workpiece is guided by gradually narrowing to avoid bias caused by the transfer through two belts, effectively ensuring that the workpiece in each dividing channel can move quickly and accordingly. Preferably, each pair of guide vanes 42 is installed on the inner wall of the front end of each dividing channel on the diversion belt 2, which is easy to install and better guides the workpiece.

[0044] refer to Figure 2 , 3For example, 7, 9, 10 or 11, a belt transition plate 41 is installed on the upper front end of both the diversion belt line 2 and the belt conveyor line 5. The two ends of the belt transition plate 41 are respectively connected to the left and right side frames of the diversion belt line 2 or the belt conveyor line 5. The belt transition plate 41 fills the gap between the head and tail belts of the feeding belt line 1, the diversion belt line 2 and the belt conveyor line 5, so that the test card workpiece is well prevented from falling out of the gap during the transfer process, and it is also easier to connect without having to make excessive compromises on the gap.

[0045] refer to Figure 2-7, 9-11, for example, profile frames 43 are provided on both sides of the feeding belt 1, both sides of the diversion belt 2, and both sides of the belt conveyor 5. A connecting groove extending axially is provided on the outer wall of the profile frame 43, and a gantry bracket 44 for installing sensors, height limit bars 26, channel gates 22, or other components is installed across the dividing channel on the profile frame 43. The gantry bracket 44 can be adjusted axially along the profile frame 43. The components include a material collection sensor 21, a channel gate 22, a guide rail 23, a diversion release sensor 24, and a full material sensor. Device 25, height limit bar 26, material blockage sensor 27, and other components can all be connected to the gantry bracket 44, thereby fixing them as needed on the feeding conveyor belt 1 and the diversion conveyor belt 2 while avoiding friction with the belts. Preferably, the crossbeam on the gantry bracket 44 is also a profile with connecting grooves on the side wall, which allows each component to be easily fixed in any position along the connecting groove. This allows these sensors, rods, and guardrails to be easily installed in the lateral direction. At the same time, they are connected to the connecting groove of the profile frame 43 by bolts. The entire gantry bracket 44 can be adjusted and fixed in the front-back direction along the feeding conveyor belt 1 or the diversion conveyor belt 2. The installation and assembly of the two conveyor belts are highly flexible and convenient. The belt transition plate 41 can also be easily installed via the profile frame 43. The plasma treatment device 61, color mark trigger 62, inkjet printer 63, UV curing unit 64, visual recognition device 65, and guide plate 51 are each connected to the profile frame 43 via a gantry bracket 44. The bottom of the left and right ends of the gantry bracket 44 are respectively connected to the profile frames 43 on both sides of the conveyor belt 5 and can be adjusted axially. Preferably, the crossbeam on the gantry bracket 44 is also a profile with connecting grooves on the side walls, which allows each component to be easily adjusted axially. The connecting slot is selected at a fixed position, which allows for convenient installation of various components. At the same time, the two ends of the gantry bracket 44 are connected to the connecting slot of the profile frame 43 by bolts. The entire gantry bracket 44 can be adjusted and fixed along the front and rear directions of the belt conveyor line 5, making the erection or assembly of the two belt lines very flexible and convenient. Moreover, the profile has good versatility and repeatability. In addition, the gantry bracket 44 can be adjusted and connected axially by using the existing slider in conjunction with the conventional slide rail set on the profile frame 43. The guide plate 51 is connected to the gantry bracket 44 by a vertical connecting plate or connecting rod, making installation and adjustment easy.

[0046] refer to Figure 2-6. For example, the dividing channel includes several channel baffles 31. The channel baffles 31 and the guide rails 23 are connected to the gantry bracket 44 by vertical connecting rods. Because the connecting rods can be fixed by adjusting the gantry bracket 44 laterally, the channel baffles 31 and the guide rails 23 can be flexibly set to be parallel to or at an angle to the front and rear direction of the belt line through the connecting rods. Moreover, they can be installed with other components using the same connectors. The two channel baffles 31 can form a spaced channel to allow the workpiece to be moved on the belt line. The width or number of dividing channels can also be easily adjusted to adapt to different needs.

[0047] refer to Figure 8 For example, the guide rail 23 is connected to a pressure plate 28, which is located between two guide rails 23. The guide rail 23 is also a profile and has a connecting groove extending axially on its upper side. One side of the pressure plate 28 is connected to the connecting groove of the pressure plate 28 by bolts or screws, so that the pressure plate 28 can be adjusted and installed along the guide rail 23. The pressure plate 28 is limited from above. Preferably, the front end of the pressure plate 28 is provided with an arc-shaped upward bending part, which can effectively prevent the workpiece from flipping or turning over during transportation. For example, a plasma blowing device is provided at the rear.

[0048] refer to Figure 11 and 12 For example, an adjustable seat 521 capable of being raised and lowered is installed on the profile frame 43. The adjustable seat 521 is connected to the guide rail 52 through a horizontal support rod, so the guide rail 52 can be easily adjusted horizontally along the support rod. At the same time, the adjustable seat 512 can be raised and lowered by bolts or screws, which can drive the support rod to rise and fall, thereby adjusting the height of the guide rail 52, which is very convenient.

[0049] refer to Figure 11 and 12 For example, the lower end of the adjusting seat 521 is connected to the mounting seat 522 by a vertical top rod. The mounting seat 522 is connected to the outer wall of the profile frame 43 by a horizontal bolt or screw, so that the mounting seat 522 will not interfere with other components installed on the upper side of the profile frame 43. At the same time, the mounting seat 522 can also be adjusted along the profile frame 43. Moreover, the adjusting seat 521 and the mounting seat 522 can be equipped with a tightening bolt or fastening mechanism with a handwheel to adjust the tension of the vertical top rod or the horizontal support rod, thereby better installing and adjusting the guide rail 52.

[0050] refer to Figure 7 and 11For example, the belt conveyor 5 is provided with a rejection device 66 behind the visual recognition device 65. The rejection device 66 is located on one side of the belt conveyor 5 and is provided with an air outlet facing the other side of the belt conveyor 5. When the visual recognition device 65 detects a defective product, the air outlet of the rejection device 66 blows the corresponding workpiece away from the belt conveyor 5, thereby ensuring that the belt conveyor 5 only outputs qualified products. The belt conveyor 5 is also provided with a waste recycling box 67 on the other side corresponding to the rejection device 66. The opening of the waste recycling box 67 faces the air outlet of the rejection device 66, so the rejection device 66 can directly blow the defective products into the waste recycling box 67 for centralized collection, which is very convenient. Moreover, the rejection device 66 and the waste recycling box 67 can be easily installed and adjusted through the profile frame 43.

[0051] refer to Figure 10 For example, the separating channel includes several channel baffles 32 and supports 33. The supports 33 are used to install on the side profile frame 43 of the feeding conveyor belt 1 or the diversion conveyor belt 2. The supports 33 are vertically connected to the channel baffles 32 by transverse support rods. This structure of the separating channel allows the width of the channel baffles 32 to be easily adjusted or the number of channels to be increased by moving them laterally along the support rods, while reducing the thickness occupied. This allows for more channels to be set on the same conveyor belt. Moreover, since the support rods are transverse and perpendicular to the conveyor belt, the channel baffles 32 can be aligned with the conveyor belt without adjustment. The belt conveyor is aligned front and rear, and the two ends of the support rod are hinged or connected to the support 33. The support 33 can also be flexibly adjusted by being installed on the profile frame 43. Of course, the support 33 can also be installed on other structures on the side of the belt conveyor. The lower side of the diversion belt conveyor 2 is equipped with a diversion control cabinet and an alarm light. The diversion control cabinet connects and controls various sensors, channel switches, etc. to achieve control. Moreover, the diversion control cabinet and the alarm light can move with the diversion belt conveyor, realizing modular and flexible application on the production line. When an error occurs, the alarm light can help the staff quickly locate the fault.

[0052] refer to Figure 14 For example, a pressure guide 34 capable of height adjustment is installed between the channel baffles 32. The pressure guide 34 has a continuous M-shaped structure. The pressure guide 34 is placed between the channel baffles 32 through the slots and is laterally limited. The pressure guide 34 is pressed against or abutted against the channel baffle 32 at its end by bolts or screws, so that it can be fixed at height. By flexibly using the pressure guide 34 to limit the height position between the channels, the workpiece can be prevented from jamming due to overlap.

[0053] refer to Figure 8 , 9Alternatively, for example, the lower sides of the feeding belt 1, the diversion belt 2, and the belt conveyor 5 are all connected to a platform. The bottom of the platform is equipped with casters and lifting feet. The platform can be easily moved along with the belt via the casters, so as to be conveniently arranged and connected to the production line as needed in the production area. Then, it can be fixed and supported by the lifting feet. At the same time, multiple lifting feet can be adjusted to be leveled by lifting and adjusting.

[0054] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
