Description

Technical Field

[0001] The present invention relates to the technical field of machining, and particularly to a processing line body. Background Art

[0002] Processing equipment is a key device used for physically or chemically processing parts or products in industrial production. Such equipment usually consists of a power system, a transmission mechanism, working components, and a control system, and has characteristics such as high efficiency, precision, and automation. Common processing equipment includes machine tools (such as lathes, milling machines), injection molding machines, stamping equipment, welding robots, etc., and can complete various processes such as cutting, forming, assembly, and inspection.

[0003] In the prior art, the transmission mechanism of processing equipment often arranges a transmission line to connect with other processing equipment to form a processing station or a processing line, so as to realize the automatic processing process of the workpiece from feeding to processing and then discharging. It has the following limitations: Since each processing equipment has only one transmission line, when various processing equipment are connected in series in a fixed order, it is impossible to flexibly adjust the processing order or increase or decrease the equipment, resulting in the need to reconstruct the production line structure for process changes, and it is difficult to meet the production requirements of multi-variety and small-batch production; The failure of a single device or conveyor belt is likely to cause the entire chain to collapse, lacking a redundant design mechanism, and the shutdown maintenance cost is high; There is a lack of intelligent scheduling ability between equipment, and the processing rhythm is limited by the speed of the conveyor belt, making it difficult to achieve dynamic beat matching. It is impossible to configure different numbers of processing equipment according to the different times required for each processing process, reducing the processing efficiency.

The first lifting mechanism is also used to return downward after the picking and placing mechanism picks up the unprocessed workpiece;

[0011] A first lifting blocking member is provided at a position on one side of the first lifting mechanism facing the output end of the first transfer line. The first lifting blocking member is used to rise to prevent the unprocessed workpiece from moving in the direction of the output end when the unprocessed workpiece reaches or is about to reach the first lifting mechanism.

[0019] In summary, the processing line body of the present invention has the following beneficial effects:

[0020] (1) Connect the first transmission lines of each processing device in the same processing station end to end in series, and connect the second transmission lines of each processing device in the same processing station end to end in series. Combining with the lifting blocking members provided on the first transmission line can achieve: multiple processing devices in the same processing station are connected in series to form a line body, and their processing methods are parallel processing methods, and multiple first workpieces can be processed simultaneously, greatly improving the processing efficiency. Moreover, each processing device is an independent individual. Even if one of the processing devices fails, only this processing device needs to be stopped and the faulty processing device can be removed. Since the transmission lines of each processing device are not directly connected and they are in a mutually connected relationship, even if this processing device is removed, the transmission line will not break and will not affect the normal processing of other processing devices. And the removed processing device will not generate any instruction requiring the first workpiece. Therefore, the previous processing device will not receive the demand instruction corresponding to this processing device. Therefore, when releasing the first workpiece, the first workpiece will be released in real time corresponding to the demand instruction of the current processing device.

[0021] (2) After the second transmission lines of each processing device in the same processing station complete the processing of the first workpiece to form the second workpiece, they are sequentially transmitted through the second transmission lines of the subsequent processing devices to the input end of the first transmission line of the next processing station to serve as the first workpiece of the next processing station. A corresponding program can be designed to prevent the second lifting mechanism on the second transmission line from lifting upward during the transmission of the second workpiece. For example, a probe or a detection unit can be designed at the input end of the second transmission line. If it is detected that the workpiece enters from the input end of the second transmission line, it is regarded that the workpiece is the second workpiece transmitted by the second transmission line of the previous processing device.

[0022] (3) When designing the connection between different processing stations on the processing line body, the transfer of workpieces can be achieved by connecting the input end of the first transmission line of the first processing device in the current processing station to the output end of the second transmission line of the last processing device in the previous processing station, so that the second workpiece in the previous processing station is transmitted through the second transmission line of the corresponding processing device to the first transmission line of the corresponding processing device in the next processing station. Based on this, the number of processing devices in the corresponding processing station can be configured according to the processing duration of each processing process, greatly improving the processing efficiency.

[0035] Please refer to Figure 1 , Figure 1 which exemplarily shows a schematic diagram of a simplified structure of a machining line body. The machining line body includes a plurality of machining stations. Figure 1The schematic structural diagram of a processing line composed of three processing stations is shown. Figure 1 Among them, the structure of only the transmission mechanism of each processing device is shown.

[0036] In this embodiment, the processing line is exemplarily described by taking three processing stations as an example. The three processing stations are respectively named the first processing station A, the second processing station B, and the third processing station C. The first processing station A is used to perform the first processing on the workpiece based on the first processing procedure (for example, the first workpiece assembly), the second processing station B is used to perform the second processing on the workpiece based on the second processing procedure (for example, the second workpiece assembly), and the third processing station C is used to perform the third processing on the workpiece based on the third processing procedure (for example, detecting the assembled workpiece).

[0037] In this embodiment, the first processing station A is configured with a processing device (hereinafter referred to as processing device A), the second processing station B is configured with two processing devices (hereinafter referred to as processing device B1 and processing device B2), and the third processing station C is configured with two processing devices (hereinafter referred to as processing device C1 and processing device C2). It should be understood that the number of processing stations and processing devices here are all used as exemplary examples. The number of processing stations should be at least one, and the number of processing devices for each processing station should also be at least one.

[0038] The first processing station A, the second processing station B, and the third processing station C are connected in series in sequence, that is, the output end of the first processing station A is connected to the input end of the second processing station B, and the output end of the second processing station B is connected to the input end of the third processing station C. Each processing device (when there are multiple processing devices) of each processing station is also connected in series end to end in sequence, that is, the first processing device of the processing station is connected to the previous processing station or the loading position, and the last processing device of the processing station is connected to the next processing station or the unloading position.

[0039] Each of the above processing devices includes a transmission mechanism 110, a processing mechanism 120, and a feeding and taking mechanism 130. The transmission mechanism 110 of each processing device includes a first transmission line T1 and a second transmission line T2 arranged side by side. The first transmission line T1 is used to transmit the first workpiece G1 (unprocessed workpiece, see Figure 2 ), and the second transmission line T2 is used to transmit the second workpiece G2 (the workpiece processed by the current processing mechanism 120, see Figure 3 ). The processing device A of the first processing station A is a corresponding workpiece assembly mechanism, the processing mechanism 120 of the second processing station B is a corresponding workpiece assembly mechanism, and the processing mechanism 120 of the third processing station C is a corresponding detection mechanism.

[0040] The input end of the first transmission line T1 of the processing device A can be connected to a loading machine for receiving the first workpiece G1. The second transmission line T2 of the processing device A is arranged side by side with the first transmission line T1.

[0041] The input end of the first transmission line T1 of the processing device B1 of the second processing station B is connected to the output end of the second transmission line T2 of the processing device A, and is used to receive the second workpiece G2 from the processing device A and use it as the first workpiece G1 of the processing device B1. The second transmission line T2 of the processing device B1 is preferably coaxially arranged with the first transmission line T1 of the processing device A. The input end of the first transmission line T1 of the processing device B2 is connected to the output end of the first transmission line T1 of the processing device B1, and is used to receive the first workpiece G1 from the processing device B1. The input end of the second transmission of the processing device B2 is connected to the output end of the second transmission line T2 of the processing device B1 to receive the second workpiece G2 from the processing device B1.

[0042] The input end of the first transmission line T1 of the processing device C1 of the third processing station C is connected to the output end of the second transmission line T2 of the processing device B2, and is used to receive the second workpiece G2 from the processing device B2 and use it as the first workpiece G1 of the processing device C1. The second transmission line T2 of the processing device C1 is preferably coaxially arranged with the first transmission line T1 of the processing device B2. The input end of the first transmission line T1 of the processing device C2 is connected to the output end of the first transmission line T1 of the processing device C1, and is used to receive the first workpiece G1 from the processing device C1. The input end of the second transmission line T2 of the processing device C2 is connected to the output end of the second transmission line T2 of the processing device C1 to receive the second workpiece G2 from the processing device C1. The output end of the processing device C2 is connected to the blanking position to transfer the second workpiece G2 that has been sequentially transferred to the second transmission line T2 of the processing device C2 to the blanking position.

[0043] Please refer to Figures 2 to 5 , which exemplarily shows a schematic diagram of the simplified structure of the processing device and the processing station. Figure 2 It shows the state where the workpiece carrier loaded with the unprocessed workpiece is located at the first lifting mechanism. Figure 3 It shows the state where the workpiece carrier is lifted by the second lifting mechanism and the workpiece is in the processing process. The processing device here refers to the mechanical equipment used in any process during the manufacturing process of the product, and these processes include but are not limited to product processing, assembly, inspection, etc. For example, processing devices for any kind of processing of workpieces, such as cutting, punching, milling and other processing devices. For example, assembly devices for any kind of assembly of workpieces, such as bonding, assembling, connecting and other processing devices. For example, inspection devices for inspecting workpieces, such as product size, product appearance and other inspection devices.

[0044] Each of the processing devices includes a transmission mechanism 110, a processing mechanism 120, and a loading and unloading mechanism 130. The processing device may further include other well-known structures. Since these structures are not within the scope of the improvement of the present invention, they are not shown in the drawings and related text. In addition, the processing mechanism 120 is configured corresponding to different processing methods, and its structure may adopt any one of the existing well-known processing mechanisms 120. Therefore, the processing mechanism 120 is represented by a box in the drawings. Similarly, the loading and unloading mechanism 130 may also adopt any one of the existing well-known loading and unloading structures, such as a loading and unloading mechanism 130 combining a three-axis module and a picking component, or a manipulator, etc. Therefore, the loading and unloading mechanism 130 is also represented by a box in the drawings.

[0045] In the illustrated embodiment, the transmission mechanism 110 of each processing device includes a first transmission line T1 and a second transmission line T2 arranged side by side. Taking the transmission direction of the transmission mechanism 110 as the length direction, the first transmission line T1 and the second transmission line T2 are arranged side by side along the width direction perpendicular to the length direction. The structures of the first transmission line T1 and the second transmission line T2 may adopt any one of the existing transmission structures in the prior art, and will not be elaborated here in detail.

[0046] The first transmission line T1 is used to transmit unprocessed workpieces (first workpieces G1), and the second transmission line T2 is used to transmit workpieces (second workpieces G2) processed by the processing mechanism 120 and transmit the second workpieces G2 to the target position. The loading and unloading mechanism 130 is used to pick up the first workpiece G1 at the first transmission line T1 and feed it to the processing station for the processing mechanism 120 to process the first workpiece G1. The loading and unloading mechanism 130 is also used to feed the second workpiece G2 at the processing station to the second transmission line T2 for the second transmission line T2 to transmit the second workpiece G2 to the target position. The target position is determined according to the current processing node of the workpiece. For example, the target position may be the input end of the first transmission line T1 of the next different processing device, the input end of the second transmission line T2 of the next same processing device, the unloading position, or the buffer position, and a rotatable deflector is provided at the buffer position.

[0047] When the first workpiece G1 completes the current processing at the current processing device to form the second workpiece G2 and needs to perform the next different processing operation, the second transmission line T2 transmits the second workpiece G2 to the input end of the first transmission line T1 of the next different processing device (the processing device corresponding to the next processing operation, and the next processing operation is different from the current processing operation). When the second workpiece G2 enters the input end of the first transmission line T1 of the next different processing device, it serves as the first workpiece G1 (unprocessed workpiece) of the next different processing device.

[0048] In an embodiment in which multiple identical processing devices are connected in series end to end, the first transmission line T1 of each processing device is connected to the first transmission line T1 of the adjacent processing device, so that each processing device can obtain the first workpiece G1 through the mutually connected first transmission lines T1. The second transmission line T2 of each processing device is connected to the second transmission line T2 of the adjacent processing device, so that each processing device can obtain the second workpiece G2 through the mutually connected second transmission lines T2, until the second transmission line T2 of the last processing device transfers the workpiece to the next processing station or the blanking position. In this embodiment, if the current processing device is not the last device in the series connection, the second workpiece G2 formed after being processed by the current processing device is transmitted by the second transmission line T2 to the input end of the second transmission line T2 of the next processing device until it is transmitted to the output end of the last second transmission line T2. The output end of the last second transmission line T2 selects whether to transmit the workpiece to the input end of the first transmission line T1 of the next different processing device, the blanking position or the buffer position according to whether the current processing node is the last processing node.

[0049] If the current processing node is not the last processing node, the last processing device can transmit the second workpiece G2 to the input end of the first transmission line T1 of the next processing station (the next different processing device) through the second transmission line T2. If the current processing node is the last processing node, the last identical processing device can transmit the second workpiece G2 to the blanking position through the second transmission line T2. If it is necessary to extract the second workpiece G2 for inspection after the current processing node is processed, the second conveyor line of the last identical processing device or the current processing device can transmit the workpiece to the buffer position through a branch output line or a loading and unloading mechanism 130, waiting for the AGV trolley or other devices to conduct a spot check on the extracted second workpiece G2.

[0050] In an embodiment, in order to facilitate the loading and unloading mechanism 130 to pick up the first workpiece G1 more conveniently. The present invention can configure the first transmission line T1 as a first transmission line T1 that can be paused (the driving device of the first transmission line T1 is connected to the controller, and the controller controls the start and stop of the driving device after receiving the sensor signal), so as to realize the function of pausing the first workpiece G1, so that the first workpiece G1 is paused at a certain position to wait for the loading and unloading mechanism 130 to accurately pick up the workpiece. Of course, this embodiment is not used to limit the present invention.

[0051] In another embodiment, for the convenience of the pick-and-place mechanism 130 to pick up the first workpiece G1 more easily, a first lifting stopper 111 may be provided on the transmission path of the first transmission line T1. The first lifting stopper 111 is used to block the first workpiece G1 that reaches here. The pick-and-place mechanism 130 is used to pick up the first workpiece G1 blocked by the first lifting stopper 111 and feed it to the processing station. The first lifting stopper 111 can be suspended above the first transmission line T1 through a bracket. In this solution, the first lifting stopper 111 can be lowered to the first transmission line T1 to block the first workpiece G1 that reaches here. Preferably, the first lifting stopper 111 can also be provided below the first transmission line T1. For example, the first transmission line T1 includes two parallel conveyor chains, and a space is formed between the two parallel transmission chains. The first lifting stopper 111 is provided at this space. In this solution, the first lifting stopper 111 can be raised above the first transmission line T1 to block the first workpiece G1 that reaches here.

[0052] In yet another embodiment, for the convenience of the pick-and-place mechanism 130 to pick up the first workpiece G1 more easily, a first lifting mechanism 112 is provided on the transmission path of the first transmission line T1. The platform surface of the first lifting mechanism 112 is provided with anti-slip lines; the first lifting mechanism 112 is used to lift the first workpiece G1. The pick-and-place mechanism 130 is used to pick up the first workpiece G1 on the first lifting mechanism 112 and feed it to the processing station, and the first lifting mechanism 112 is also used to return downward after the pick-and-place mechanism 130 picks up the first workpiece G1.

[0053] In this embodiment, a first lifting stopper 111 and a first lifting mechanism 112 are provided on the transmission path of the first transmission line T1. The first lifting stopper 111 is disposed on the side of the first lifting mechanism 112 facing the output end, or the first lifting stopper 111 is close to the side of the first lifting mechanism 112 facing the output end. The first lifting stopper 111 is used to rise to prevent the first workpiece G1 from moving in the direction of the output end when the first workpiece G1 reaches or is about to reach the first lifting mechanism 112. The first lifting mechanism 112 is used to lift the first workpiece G1 upward for the pick-and-place mechanism 130 to accurately pick up the first workpiece G1, and the first lifting mechanism 112 is also used to return downward after the pick-and-place mechanism 130 picks up the workpiece. The first lifting stopper 111 is used to return downward based on a relevant return instruction or to remain in the upward blocking state according to a relevant holding instruction.

[0054] Based on this embodiment, a workpiece carrier G is provided. The workpiece carrier G is provided with a plurality of workpiece loading positions and can load a plurality of workpieces. The workpiece carrier G loaded with a plurality of first workpieces G1 is placed on the first transmission line T1. When the workpiece carrier G is conveyed to the first lifting mechanism 112, the first lifting and blocking member 111 rises upward to block the workpiece carrier G from continuing to move in the conveying end direction. At this time, the first lifting mechanism 112 lifts the workpiece carrier G upward to make it leave the first transmission line T1, and the linked picking and feeding mechanism 130 moves to the first lifting mechanism 112 to pick up the workpiece carrier G. The picking and feeding mechanism 130 can move the workpiece carrier G to a designated position according to different design or implementation requirements. The designated position can be a processing station or a certain position between the transmission mechanism 110 and the processing station.

[0055] In this embodiment, a second lifting mechanism 113 is provided on the transmission path of the second transmission line T2. When the second lifting mechanism 113 is in the lifting state, it serves as the designated position. The second lifting mechanism 113 can be configured to lift simultaneously or successively with the first lifting mechanism 112 when the workpiece reaches the first lifting mechanism 112. The platform surface of the second lifting mechanism 113 is provided with anti-slip lines;. The second lifting mechanism 113 can also be configured to lift upward when the picking and feeding mechanism 130 picks up the first workpiece G1 from the first lifting mechanism 112. The picking and feeding mechanism 130 is used to feed the workpiece carrier G picked up from the first lifting mechanism 112 to the second lifting mechanism 113 in the lifting state. The picking and feeding mechanism 130 is also used to feed the first workpieces G1 in the workpiece carrier G to the processing station one by one. The picking and feeding mechanism 130 is also used to alternately feed the workpieces processed at the processing station to the workpiece carrier G at the second lifting mechanism 113. The term "alternately" here means that after the picking and feeding mechanism 130 picks up a first workpiece G1 to the processing station, it retrieves the second workpiece G2 (the processed workpiece) at the processing station and places it in the empty workpiece loading position of the workpiece carrier G, and so on, alternately picking and feeding the first workpiece G1 and the second workpiece G2 back and forth. When all the workpieces in the workpiece carrier G at the second lifting mechanism 113 are second workpieces G2, that is, after the workpieces in the workpiece carrier G are processed, the second lifting mechanism 113 returns downward to make the workpiece carrier G loaded with the second workpiece G2 be transmitted by the second transmission line T2 to the target position.

[0056] During the machining process of a workpiece, the machining time lengths of each machining node may not be the same. For example, the machining time length of the current machining node is twice or more than twice that of the previous or next machining node. That is to say, when the current machining equipment processes a workpiece, the previous machining equipment can process two or more workpieces simultaneously. Corresponding to this situation, in order to make the rhythm of the current machining node adapt to the machining rhythm of the corresponding machining node, two or more identical machining equipment can be connected in series, so that two or more machining equipment can process the first workpiece G1 reaching this machining node when they are idle, thereby achieving the purpose of parallel processing of the first workpiece G1 by multiple identical machining equipment.

[0057] Based on this, at least one second lifting stopper 114 may be further provided on the path of the first transmission line T1 of the processing equipment. The second lifting stopper 114 is located between the first lifting stopper 111 and the input end of the first transmission line T1. A first blocking position is formed in the area on the side of the first lifting stopper 111 facing the second lifting stopper 114, and the first lifting mechanism 112 is located at the first blocking position. An area on the side of the second lifting stopper 114 facing the input end forms a second blocking position. The second lifting stopper 114 is configured to rise upward when a first workpiece G1 is blocked at the first blocking position, so as to block the first workpiece G1 located at the second blocking position from entering the first blocking position. Both the first lifting stopper 111 and the second lifting stopper 114 are further configured to return downward according to relevant release instructions to release the first workpiece G1, so that the first workpiece G1 is transmitted through the first transmission line T1 to the first conveyor line of the next identical processing equipment connected in series. The relevant release instructions may be triggered based on the following conditions: the current processing equipment is in the processing process, and the subsequent identical processing equipment connected in series is in the idle state, causing the corresponding second stopper and the first lifting stopper 111 to return downward to release the first workpiece G1 into the processing equipment in the idle state. The relevant release instructions may also be triggered based on the following conditions: both the current and the subsequent identical processing equipment connected in series are in the processing process, but the second blocking position and / or the first blocking position of the subsequent identical processing equipment connected in series are in the vacant state (i.e., there is no new first workpiece G1). Based on the release instructions, the second lifting stopper 114 and the first lifting stopper 111 are caused to return downward to release the first workpiece G1 so that it reaches the first transmission line T1 of the corresponding identical processing equipment (at least causing the first workpiece G1 to reach the first blocking position of the first transmission line T1, and the first workpiece G1 cannot exceed the first lifting stopper 111 in the conveying direction), making the first workpiece G1 a reserve workpiece for the subsequent identical processing equipment connected in series. After the subsequent identical processing equipment connected in series finishes processing the current first workpiece G1, the first lifting mechanism 112 is caused to lift the reserved first workpiece G1 for another round of workpiece processing, and so on. Of course, the relevant release instructions may also be set based on the application scenarios and design requirements of different embodiments, causing the first lifting stopper 111 and the second lifting stopper 114 to descend synchronously or at different times. The first lifting stopper 111 and the second lifting stopper 114 may automatically rise after releasing one or more first workpieces G1.

[0058] Please refer to Figure 4, Exemplarily, the first processing device located on the left and the last processing device located on the right are connected in series through a transmission mechanism 110, that is, the output end of the first transmission line T1 of the first processing device is connected to the input end of the first transmission line T1 of the last processing device, and the output end of the second transmission line T2 of the first processing device is connected to the input end of the second transmission line T2 of the last processing device. The two processing devices are the same processing devices that perform the same processing operation, and the two processing devices form a processing station. It should be understood that in some embodiments, the processing station may include only one processing device or may include multiple identical processing devices connected in series. In the transmission path of the first transmission line T1 of each processing device, a second lifting blocking member 114, a first lifting mechanism 112, and a first lifting blocking member 111 may be sequentially arranged along the conveying direction. A second lifting mechanism 113 may be provided at a position corresponding to the first lifting mechanism 112 on the second transmission line T2 of each processing device. When the first workpiece G1 reaches the first lifting mechanism 112, the first lifting blocking member 111 and the first lifting mechanism 112 rise upward to separate the first workpiece G1 from the first transmission line T1, and the second lifting blocking member 114 also rises upward for preventive purposes. If a first workpiece G1 enters the second blocking position when the first lifting mechanism 112 is in the lifting state, the second lifting blocking member 114 can block the first workpiece G1. When the first workpiece G1 on the first lifting mechanism 112 is taken away and during the processing period, and the last processing device is in an idle state (unprocessed state) or the last processing device is in a processing state and there is no reserved first workpiece G1, the second lifting blocking member 114 returns downward to release the first workpiece G1 here to the first blocking position. If the first lifting blocking member 111 is in the rising state at this time, the first lifting blocking member 111 is made to return downward to release the first workpiece G1. If the first lifting blocking member 111 is in the return state at this time, the first workpiece G1 is directly conveyed by the first conveyor line to the input end of the first conveyor line of the last processing device. When the second lifting blocking member 114 and the first lifting blocking member 111 descend and release, it can be realized based on detection technologies such as CCD and infrared that only one first workpiece G1 (such as one workpiece carrier G) can pass through at a time, that is, only one first workpiece G1 passes through each time of descending and releasing. It can also be realized based on detection technologies such as CCD and infrared that multiple first workpiece G1 are released at a time, so that the number of released first workpiece G1 corresponds to the number of the subsequent multiple identical processing devices, and the multiple first workpiece G1 are respectively released to the first transmission lines T1 of each identical processing device.

[0059] Please refer to Figure 5, Exemplarily, three identical processing devices located on the left, middle, and right respectively form a processing station. The first transmission line T1 of the first processing device on the left, the second processing device in the middle, and the last processing device on the right are connected end to end, and the second transmission line T2 is also connected end to end. On each processing device, a second lifting and blocking member 114, a first lifting mechanism 112, and a first lifting and blocking member 111 are sequentially arranged along the conveying direction. The functions of the second lifting and blocking member 114, the first lifting mechanism 112, and the first lifting and blocking member 111 are all the same as or similar to those Figure 4 shown. The subtle difference is that: the second lifting and blocking member ********** of the first processing device can determine the release quantity of the first workpiece G1 based on the processing states of the second processing device and the last processing device (when the quantity of the first workpiece G1 at the second lifting and blocking member 114 is satisfied). For example, when both the second processing device and the last processing device are in the processing state and there is no reserved first workpiece G1 at both of them, the first processing device controls the second lifting and blocking member 114 and the first lifting and blocking member 111 to release two first workpieces G1, so that the first transmission line T1 transports the two first workpieces G1 to the second lifting and blocking member 114 of the first transmission line T1 of the second processing device; the second processing device controls the second lifting and blocking member 114 and the first lifting and blocking member 111 to release one first workpiece G1 (the other remains at the second processing device), so that the first transmission line T1 transports this first workpiece G1 to the second lifting and blocking member 114 or the first lifting and blocking member 111 of the last processing device, thereby enabling each subsequent series-connected processing device to have a reserved first workpiece G1. The release of the second lifting and blocking member 114 and the first lifting and blocking member 111 of each processing device can be triggered by the processing state of the next device (such as no reserved first workpiece G1 or idle state). For example, when the series-connected processing devices are in the idle state, a status instruction is sent to the control system, and the control system controls the release of the first workpiece G1 through the previous device or the first device, so that the first workpiece G1 is transported to the processing device that sends the instruction.

[0060] Based on the above embodiments, the processing flow of the workpiece is as follows:

[0061] First, load the first workpiece G1 onto the first transmission line T1 of the processing device A. The loading and unloading mechanism 130 of the processing device A feeds the first workpiece G1 to the processing station for processing, and feeds the second workpiece G2 formed after processing to the second transmission line T2 of the processing device A, which is used to transport the second workpiece G2 to the first transmission line T1 of the processing device B1 of the second processing station B.

[0062] It should be noted that there is an unclear part in the original text marked with "**********" in the translation of , which needs to be further clarified in the original text for more accurate translation.Secondly, the processing equipment B1 of the second processing station B takes the second workpiece G2 arriving at the first transmission line T1 as the first workpiece G1 to implement the processing of the first workpiece G1. The process can refer to the above-mentioned processing equipment A. At the same time, if the processing equipment B2 is in an idle state and there are multiple first workpieces G1 on the first transmission line T1 of the processing equipment B1, the first workpiece G1 is conveyed through the first transmission line T1 to the first transmission line T1 of the processing equipment B2, so that the processing equipment B2 and the processing equipment B1 process their respective first workpieces G1 respectively.

[0063] After the processing equipment B1 finishes processing, its second workpiece G2 is placed on the second transmission line T2 of the processing equipment B1. The second transmission line T2 conveys the second workpiece G2 to the second transmission line T2 of the processing equipment B2 and conveys it to the first transmission line T1 of the third processing station C through the second transmission line T2 of the processing equipment B2. After the processing equipment B2 finishes processing, its second workpiece G2 is directly transmitted to the first transmission line T1 of the third processing station C through the second transmission line T2 of the processing equipment B2.

[0064] Finally, the processing equipment C1 of the third processing station C takes the second workpiece G2 arriving at the first transmission line T1 as the first workpiece G1 to implement the processing of the first workpiece G1. The processing process of the processing equipment C1, the processing process of the processing equipment C2, and the process of the first workpiece G1 being transmitted to the processing equipment C2 can all refer to the description of the second processing station B and will not be elaborated here one by one.

[0065] After the processing equipment C1 finishes processing, its second workpiece G2 is placed on the second transmission line T2 of the processing equipment C1, so that the second workpiece G2 enters the blanking position after passing through the second transmission line T2 of the processing equipment C2. After the processing equipment C2 finishes processing, its second workpiece G2 is directly transmitted to the blanking position by the second transmission line T2 of the processing equipment C2.

[0066] In summary, the multiple processing stations of the processing line body are connected in series in sequence, and the processing procedures corresponding to each processing station are different. The input end of the first transmission line T1 of the first processing equipment of each processing station is connected in series with the output end of the second transmission line T2 of the last processing equipment of the adjacent previous processing station. Among the multiple identical processing equipment of each processing station, the first transmission lines T1 of each processing equipment are connected in series in sequence, and the second transmission lines T2 of each processing equipment are connected in series in sequence. The structures or functions of the components (such as various lifting stoppers and lifting mechanisms) provided on the first transmission line T1 and the second transmission line T2 of each processing equipment can refer to the description of the embodiments shown above and will not be elaborated here one by one.

[0067] In addition, the processing line body can also be provided with some modules, devices or systems for automated processing. The processing line body is turned into a fully automated production line, and each processing parameter and each device state of each processing device in the processing line body can be monitored, statistically analyzed or control instructions can be issued through the system. These modules, devices or systems can adopt any known method to realize the entire automatic production process from loading to unloading of the line body. For example, various device state detection modules can be set on each processing device to detect the production state of the device, and data acquisition modules can be set on each processing device to scan or obtain relevant data of the workpiece to be processed, so as to track the entire processing process of the workpiece, obtain the entire parameter data related to the workpiece, and realize real-time monitoring of the processing rhythm, processing links, yield rate, etc. of the workpiece. Data acquisition modules can be provided on each of the processing devices, and the data acquisition modules are used to acquire production data, and the production data includes processing process data, processing time efficiency data, device state data and / or processing process data. Each processing device can upload local data to the control system through an industrial control computer, and the industrial control computer is also used to issue corresponding control instructions to the corresponding processing device to make the processing device execute the control instructions. For example, in the above embodiment, each lifting mechanism, lifting and blocking member, processing mechanism 120, and material fetching and feeding mechanism 130 realize related actions through relevant control instructions, so as to realize the functions of each component shown in this text and the appended claims.

[0068] Based on the embodiments shown above, the processing line body of the present invention has the following beneficial effects:

[0069] (1) The first transmission lines of each processing device in the same processing station are connected end to end in series, and the second transmission lines of each processing device in the same processing station are connected in series with each other. Combining with the lifting and blocking members provided on the first transmission line can achieve: multiple processing devices in the same processing station are connected into a line body in a series manner, but their processing methods are parallel processing methods, and multiple first workpieces can be processed simultaneously, greatly improving the processing efficiency. Moreover, each processing device is an independent individual. Even if one of the processing devices fails, only this processing device needs to be stopped and the faulty processing device can be removed. Since the transmission lines of each processing device are not directly connected and are in a connected relationship with each other, even if this processing device is removed, the transmission line will not break and will not affect the normal processing of other processing devices. And the removed processing device will not generate any instruction for the first workpiece. Therefore, the previous processing device will not receive the demand instruction corresponding to this processing device. Therefore, when releasing the first workpiece, the first workpiece will be released in real time corresponding to the demand instruction of the current processing device.

[0070] (2) After the second transmission line of each processing device at the same processing station forms the second workpiece after the first workpiece is processed, it is sequentially transmitted through the second transmission lines of the subsequent processing devices to the input end of the first transmission line of the next processing station to serve as the first workpiece of the next processing station. A corresponding program can be designed to prevent the second lifting mechanism on the second transmission line from lifting upward during the transmission of the second workpiece. For example, a probe or a detection unit can be designed at the input end of the second transmission line. If it is detected that the workpiece enters from the input end of the second transmission line, it is regarded that the workpiece is the second workpiece transmitted by the second transmission line of the previous processing device. It should be understood that this is only an example. In fact, as long as the second transmission lines of each subsequent processing device need to sequentially transmit the second workpiece, any method that can prevent the second lifting mechanism from lifting upward during this process can be used.

[0071] (3) When designing the connection between different processing stations on the processing line body, the transfer of the workpiece can be achieved by connecting the input end of the first transmission line of the first processing device at the current processing station to the output end of the second transmission line of the last processing device at the previous processing station, so that the second workpiece at the previous processing station is transmitted through the second transmission line of the corresponding processing device to the first transmission line of the corresponding processing device at the next processing station. Based on this, the number of processing devices at the corresponding processing station can be configured according to the processing duration of each processing step, greatly improving the processing efficiency.

[0072] The above embodiments only represent the preferred implementation modes of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
