[0039] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0040] As mentioned in the background section, in the layout of a sorting system, the valve body is located inside the valve assembly box, and the control board electrically connected to the valve body is usually located in the main control system. Therefore, a large number of wiring harnesses are required between the main control system and the valve assembly box. However, due to the large number of wiring harnesses, there are significant safety hazards and high wiring costs.

[0041] Please refer to Figure 1 and Figure 4The sorting mechanism 100 and sorting system 1000 provided in the embodiments of this utility model can solve the above problems, and will be described in detail below.

[0042] The sorting mechanism 100 is applied to the sorting system 1000. The sorting mechanism 100 includes a valve assembly box 110, a valve body 120, a control board 130, and a wiring harness 190. The valve body 120 and the control board 130 are both located in the valve assembly box 110. The control board 130 is connected to the wiring harness 190, which is used to connect to the main control system 400. The valve body 120 is electrically connected to the control board 130.

[0043] The sorting mechanism 100 reduces the number of wires outside the valve assembly box 110 by installing the control board 130 inside the valve assembly box 110 and using the wiring harness 190 to achieve electrical connection between the main control system 400 and the control board 130. This reduces the safety hazards and costs associated with wiring and improves the aesthetics of the wiring.

[0044] It is worth noting that there are at least two control boards 130, and two adjacent control boards 130 are spaced apart and electrically connected; for example, when there are two control boards 130, the two control boards 130 are electrically connected to each other; when there are three or more control boards 130, the three control boards 130 can be electrically connected in sequence or connected in a triangular arrangement.

[0045] Please refer to Figure 1 When the number of valve bodies 120 is at least three, the at least three valve bodies 120 are arranged at equal intervals. Specifically, the at least three valve bodies 120 can be arranged in a straight line with intervals, or the at least three valve bodies 120 can be arranged in a polygonal pattern with intervals.

[0046] When the valve body 120 receives a signal from the control board 130 during operation, it will spray air, thereby causing the product to move to the target position under the action of airflow. The valve body 120 can selectively spray air onto the product, thereby realizing the sorting operation of the product.

[0047] Furthermore, during wiring, the wire harness 190 will pass through the side wall of the valve assembly box 110. Corresponding wiring holes can be opened in the side wall of the valve assembly box 110, and then the wire harness 190 is sealed after passing through to prevent dust and impurities from entering the valve assembly box 110, thereby reducing the negative impact of external impurities on the control board 130 and the valve body 120.

[0048] In this embodiment, there are two control boards 130, which are connected by wires. Specifically, the wires can be flexible wires or rigid wires, and the wires can be fixed to the inner wall of the valve assembly box 110 or spaced apart from the inner wall of the valve assembly box 110.

[0049] In this embodiment, both control boards 130 are rectangular, and their arrangement direction is consistent with their length direction, which can also be understood as the two control boards 130 being arranged side-by-side. Of course, in other embodiments of this invention, the number of control boards 130 can be three, four, six, etc., and adjacent control boards 130 are connected by wires. The specific number of control boards 130 is not limited. Furthermore, the arrangement direction of multiple control boards 130 can also be consistent with the width direction of their rectangles; the specific layout of multiple control boards 130 is not limited. When there are multiple control boards 130 arranged sequentially along a straight line, the multiple control boards 130 can be arranged at equal intervals.

[0050] Furthermore, the multiple control boards 130 can also be arranged in multiple rows and columns, or in an enclosed shape, or in an interlaced line shape. There is no limitation on the specific arrangement of the multiple control boards 130.

[0051] In this embodiment, there are eleven valve bodies 120, which are arranged in a straight line at equal intervals. The eleven valve bodies 120 can be selectively electrically connected to one of the two control boards 130. Of course, in other embodiments of this utility model, the number of valve bodies 120 can also be three, six, nine, twelve, etc., and the specific number of valve bodies 120 is not limited.

[0052] In addition, multiple valve bodies 120 can also be arranged in multiple rows and columns, or in an enclosed shape, or in an interlaced line shape. There is no limitation on the specific arrangement of multiple valve bodies 120.

[0053] Please refer to Figure 1 To improve layout regularity, when there are at least two valve bodies 120, the control board 130 is located below at least two valve bodies 120, and the wiring harness 190 is connected to the side of the control board 130 away from the valve body 120, so that there is sufficient distance between the wiring harness 190 and the valve body 120 and they will not have a negative impact on each other.

[0054] Meanwhile, when there are at least two control boards 130, the wires between adjacent control boards 130 can be connected to the side of the control board 130 away from the valve body 120.

[0055] Please refer to Figure 1 and Figure 2To improve the ease of installation of the control board 130, the sorting mechanism 100 may also include a first mounting plate 140. One side of the first mounting plate 140 is connected to the inner wall of the valve assembly box 110, and the control board 130 is detachably connected to the other side of the first mounting plate 140. When the control board 130 is damaged, it can be removed from the first mounting plate 140 through a detachable connection, thereby ensuring the convenience of maintenance operations.

[0056] Specifically, the control board 130 and the first mounting plate 140 can be connected by bolts, pins, or snaps; there are no limitations on their detachable connection method. Furthermore, the first mounting plate 140 can be welded to the inner wall of the valve assembly box 110, or it can be bonded, snap-fitted, or threaded.

[0057] In this embodiment, mounting holes are provided at all four corners of the control board 130 and the first mounting plate 140, that is, there are four mounting holes. Bolts or pins can be inserted into the mounting holes to connect the control board 130 and the first mounting plate 140. Of course, in other embodiments of this utility model, the number of mounting holes on the control board 130 and the first mounting plate 140 can also be two, three, five, eight, etc., and the specific number of mounting holes is not limited.

[0058] Please refer to Figure 2 To ensure the heat dissipation performance of the control board 130 and prevent overheating due to close contact between the control board 130 and the first mounting plate 140, the first mounting plate 140 can be provided with heat dissipation holes 145, and the control board 130 is located at one end of the heat dissipation holes 145. This can be understood as the control board 130 covering the end of the heat dissipation holes 145.

[0059] In this embodiment, the heat dissipation hole 145 is square-shaped, and the corners around the square hole are rounded. There is one heat dissipation hole 145, and the center of the heat dissipation hole 145 corresponds to the center of the control board 130. Of course, in other embodiments of this utility model, the heat dissipation hole 145 can also be a round hole, a triangular hole, a fan-shaped hole, a trapezoidal hole, etc., and the number of heat dissipation holes 145 can also be two, three, five, etc. The specific shape and number of heat dissipation holes 145 are not limited.

[0060] Please refer to Figure 2 and Figure 3 To further improve the heat dissipation effect, a heat dissipation gap 150 can be formed between the first mounting plate 140 and the inner wall of the valve assembly box 110. The heat dissipation gap 150 is connected to the heat dissipation hole 145. The heat on the control board 130 can be discharged outward through the heat dissipation hole 145 and the heat dissipation gap 150 in sequence, thereby achieving a good heat dissipation effect on the control board 130.

[0061] Please refer to Figure 1 and Figure 2 To improve the ease of installation of the valve body 120, the sorting mechanism 100 also includes a second mounting plate 170. One side of the second mounting plate 170 is connected to the inner wall of the valve assembly box 110, and the valve body 120 is detachably connected to the other side of the second mounting plate 170. When the valve body 120 is damaged, it can be removed from the second mounting plate through a detachable connection, thereby ensuring the convenience of maintenance operations.

[0062] In this embodiment, two lugs are formed on the valve body 120. The two lugs are detachably connected to the second mounting plate 170 by bolts. That is, each of the two lugs has a light hole, and the second mounting plate 170 has a screw hole, so that the bolt passes through the light hole and connects to the screw hole. Of course, in other embodiments of this utility model, the detachable connection between the valve body 120 and the second mounting plate 170 can also be a snap connection, a pin connection, etc., and the specific detachable connection method is not limited.

[0063] Please refer to Figure 3 To facilitate the installation and removal of the valve body 120 and control board 130 within the valve assembly box 110, the valve assembly box 110 can include a box body 111 and a cover 112, with the valve body 120 and control board 130 housed within the box body 111. Furthermore, the box body 111 and cover 112 are detachably connected. During operation, the cover 112 closes onto the box body 111, protecting the control board 130 and valve body 120. During maintenance, the cover 112 can be removed to access the components within the box body 111.

[0064] It is worth noting that, in order to reduce material costs, the box body 111 can be made into a thin-walled structure; and in order to improve the stability of the lid, the opening on the box body 111 that connects to the lid 112 can be made into a bent structure, and the lid 112 can have a certain extension thickness, so that there is sufficient contact area with the bent structure at the opening of the box body 111, thereby ensuring the stability of the lid.

[0065] Furthermore, the housing 111 has a first side wall 1111 and a second side wall 1112 arranged opposite to each other. The valve body 120 and the control board 130 are both connected to the inner wall of the first side wall 1111, and the cover 112 is connected to the second side wall 1112. This provides sufficient space for operation of the valve body 120 and the control board 130 inside the housing 111 when the cover 112 is opened, thereby improving the convenience of operation. The opening for cooperating with the cover 112 and the bending structure are both formed on the second side wall 1112.

[0066] Furthermore, in order to avoid excessive dust accumulation on the top surface of the housing 111, the top surface of the housing 111 can be inclined, specifically, the height of the top surface of the housing 111 gradually decreases along the direction from the first side wall 1111 to the second side wall 1112.

[0067] Please refer to Figure 4 The present invention also provides a sorting system 1000, a vision system 300, a main control system 400, and a sorting mechanism 100; wherein the vision system 300 and the wiring harness 190 are electrically connected to the main control system 400.

[0068] Specifically, the vision system 300 includes a camera 310 and a vision controller 320 electrically connected to each other. The vision controller 320 is electrically connected to the main control system 400. The camera 310 is used to acquire images of the products being sorted. The main control system 400 includes an embedded industrial computer 410 and an encoder 420 electrically connected to each other. The embedded industrial computer 410 is electrically connected to the vision controller 320 in the vision system 300. The encoder 420 is connected to the wiring harness 190. Both the embedded industrial computer 410 and the encoder 420 are installed in the electrical control cabinet. The embedded industrial computer 410 uses the Codesys (PLC software programming tool) programming platform, while the control board 130 is a PWM control board.

[0069] The sorting system employs an embedded industrial computer 410 based on the Codesys programming platform. The main program and Ethercat communication program are written using Codesys software. A high-speed Ethercat communication bus is used to control the I / O module 430 in the main control system 400 and the valve body 120 in the sorting mechanism 100. The encoder 420 and the PWM control board both support the Ethercat communication protocol. The sorting system also includes a conveying assembly. The conveying inverter 210 in the conveying assembly is electrically connected to the embedded industrial computer 410 and controlled via RS485.

[0070] During operation, the use of the embedded industrial computer 410, with its advantages of strong computing power, large storage space, and fast response time, can shorten the program execution cycle to 150us, greatly reducing the backward position during jetting and enabling a sorting rate of 98%. Furthermore, by adopting the Codesys programming platform, which conforms to the IEC 61131-3 standard, it has the advantages of strong versatility and portability.

[0071] This sorting system also adopts the EtherCAT bus protocol, which greatly shortens the communication cycle time to within 100µs. Therefore, controlling the valve body 120 via EtherCAT bus communication has the advantage of strong real-time performance. Combined with the sorting mechanism 100, when the main control system 400 controls the valve body 120, only one network cable is needed to connect from the electrical control cabinet to the control board 130. The control board 130 then controls the valve body 120, reducing the cabling between the electrical control cabinet and the valve assembly box 110, thus improving equipment stability and cabling aesthetics.

[0072] In summary, the sorting mechanism 100 and sorting system 1000 provided by the embodiments of this utility model have at least the following advantages:

[0073] (1) By installing the control board 130 inside the valve assembly box 110 and using the wiring harness 190 to achieve electrical connection between the main control system 400 and the control board 130, the number of wiring outside the valve assembly box 110 can be reduced, thereby reducing the safety hazards and cost of wiring, and improving the aesthetics of wiring.

[0074] (2) By detachably connecting the control board 130 and the valve body 120 to the first mounting plate 140 and the second mounting plate 170 respectively, the ease of disassembling the control board 130 and the valve body 120 is improved, thereby facilitating the separate disassembly of the control board 130 and the valve body 120 during maintenance and replacement.

[0075] (3) By opening heat dissipation holes 145 on the first mounting plate 140 and forming a heat dissipation gap 150 between the first mounting plate 140 and the inner wall of the valve assembly box 110, the heat dissipation holes 145 and the heat dissipation gap 150 are connected, thereby ensuring the heat dissipation effect of the control board 130 and preventing the control board 130 from affecting its working performance due to overheating.

[0076] (4) The use of the codesys programming platform and Ethercat bus protocol greatly shortens the overall communication time and makes the real-time control of valve body 120 stronger.

[0077] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
