Description

Technical Field

[0001] The present invention relates to the field of automation equipment, and particularly relates to a conveyor line for automatically marking states. Background Art

[0002] Currently, there are usually many workstations in automated packaging lines and automated assembly lines. The carriers on the conveyor line go through several workstations for feeding or assembly, etc., and finally finished products are produced at the end of the conveyor line. However, continuous operation of multiple workstations brings several problems: 1. For the entire production line, the more workstations there are, the greater the probability of a problem occurring at a certain workstation; 2. Once a problem occurs at a certain workstation, the corresponding semi-finished product being processed is a defective product. If subsequent workstations still feed or assemble the defective product, not only will the final output be defective, but it may also damage many workstations after the problem workstation. All workstations after the problem workstation are doing useless work, resulting in serious waste; 3. The large number of workstations makes it difficult to coordinate and control all workstations using software programs, with high costs and poor software stability; 4. Currently, most often when a problem occurs at a workstation, an automatic alarm is triggered, and all workstations on the entire production line are paused, and then manual processing is carried out, with very low efficiency; 5. There is also a method of coding each carrier, and by recording the code of the problem carrier, subsequent workstations receive instructions not to perform the next feeding or assembly on the semi-finished product on the carrier. This method has a high cost. Summary of the Invention

[0003] The technical problem to be solved by the embodiments of the present invention is to provide a production line for automatically marking states, which can physically mark the carriers, and each workstation automatically skips the carrier when detecting the mark, so that it is not necessary to pause the entire production line, with very low costs and high efficiency.

[0004] To achieve the above object, the present invention discloses a conveyor line for automatically marking states, including:

[0005] A carrier for carrying workpieces, having a sliding hole penetrating the carrier, and a slider is slidably inserted in the sliding hole, and the initial position of the slider is biased towards one side of the carrier;

[0006] A conveying device for conveying the carrier through each workstation;

[0007] A workstation detection device, and each workstation is provided with a workstation detection device for detecting whether the workstation has been successfully operated;

[0008] A marking device, which includes a push block telescopically arranged on the same side of the carrier as the initial position of the slider. When the push block extends, it pushes the slider to slide so that the slider is biased towards the other side of the carrier opposite to the initial position of the slider;

[0009] A mark detection device is provided on the other side of the carrier opposite to the initial position of the slider. The mark detection device is used to detect whether the slider deviates to the other side of the carrier opposite to the initial position of the slider.

[0010] Preferably, the length of the slider is greater than the width of the carrier so that at least one end of the slider extends out of the side wall of the carrier.

[0011] Preferably, both ends of the slider are wider than the narrowest part of the sliding hole so that the slider will not slide off the sliding hole.

[0012] Preferably, the station detection device is communicatively connected to the marking device.

[0013] Preferably, the mark detection device is communicatively connected to each station.

[0014] Preferably, a reset device is provided at the end of the conveying device. The reset device includes a reset block. The reset block is provided on the other side of the carrier opposite to the initial position of the slider. The carrier passes through all stations before passing through the reset device. When the carrier passes through the reset device, the slider that deviates to the other side of the carrier opposite to the initial position of the slider is pushed by the reset block and slides again until it deviates to the same side of the carrier as the initial position of the slider.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] By pushing the slider to deviate to the designated side of the carrier to mark whether the workpiece on the carrier is qualified, the structure is simple, reliable and has high stability. By setting a simple photoelectric head, it can be detected whether the slider deviates to one side, so as to determine whether the parts on the carrier are qualified, and the cost is very low. When each station detects the mark, the carrier is automatically skipped, so there is no need to pause the entire production line, and the efficiency is higher. Description of the Drawings

[0017] Figure 1 It is a top view schematic diagram of the overall structure of an embodiment of the present invention. Detailed Embodiments

[0018] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to Figure 1 the accompanying drawings.

[0019] Referring to Figure 1 as shown, an automatic marking state conveyor line includes a carrier 1, a conveying device 2, a marking device 4 and a mark detection device 3.

[0020] The carrier 1 is used to carry workpieces. The carrier 1 is placed on the conveying device 2 and conveyed through each station. The conveying device 2 adopts conventional conveying devices such as conveyor belts and conveyor chains. The carrier 1 has a sliding hole penetrating the carrier, and a slider 11 is slidably inserted into the sliding hole. The initial position of the slider 11 is uniformly biased to the left side of the carrier 1.

[0021] Each station is equipped with a station detection device for detecting whether the operation at the station is successful. The station detection device is set according to different requirements of different station processes. For example, an infrared ranging sensor is used to detect whether the position of the component is at the specified position.

[0022] The marking device 4 includes a push block 41 respectively and telescopically arranged on the left side of the carrier 1 and a driving device 42 for driving the push block 41 to expand and contract. The marking device 4 is communicatively connected to the station detection device. The marking device 4 drives whether the push block 41 extends according to the detection result of the station detection device. Specifically: when the station detection device at the first station detects that the operation at this station is qualified, the marking device 4 drives the push block 41 at the first station to remain retracted according to the qualified instruction. The carrier 1 continues to be conveyed by the conveying device 2 into the second station. When the station detection device at the second station detects that the operation at this station is unqualified, the marking device 4 drives the push block 41 at the second station to extend according to the unqualified instruction, and pushes the slider 11 to slide from the left side of the carrier 1 to the right side of the carrier 1. The driving device 41 can adopt conventional telescopic driving devices such as cylinders, electromagnetic push rods, electro-hydraulic push rods, and electric screws.

[0023] The marking detection device 3 is arranged on the right side of the carrier 1 for detecting whether the slider 11 is biased to the right side of the carrier 1. The marking detection device 3 adopts conventional sensors such as ranging sensors and proximity switches for detecting whether an object is approaching or exists. The marking detection device 3 is communicatively connected to each station. When the marking detection device 3 detects that the slider 11 is biased to the right side of the carrier 1, the station skips this carrier according to this information to avoid continuing to operate on this carrier.

[0024] A reset device 5 is arranged at the end of the conveying device 2. The reset device 5 includes a reset block arranged on the right side of the carrier 1. The carrier 1 only passes through the reset device 5 after being conveyed through all stations. When the carrier 1 passes through the reset device 5, if the slider 11 is biased to the right side of the carrier 1, it is pushed by the reset block and slides back to the left side of the carrier 1 to achieve reset, facilitating the next round of operation.

[0025] The length of the slider 11 is greater than the width of the carrier 1 so that at least one end of the slider 11 extends out of the side wall of the carrier 1.

[0026] Both ends of the slider 11 are wider than the narrowest part of the sliding hole so that the slider 11 will not slide off the sliding hole.

[0027] Refer to Figure 1 , the process of realizing automatic marking by the present invention is as follows:

[0028] The vehicle 1 is conveyed on the conveying device 2 and passes through several workstations in sequence. When the vehicle 1 passes through the first workstation, the marking detection device 3 arranged at the first workstation detects that the slider 11 does not deviate to the right side of the vehicle 1. According to this instruction, the first workstation can operate on the components on the vehicle 1. After the operation of the first workstation is completed, the workstation detection device of this workstation detects that the operation of this workstation is qualified. The push block 41 arranged at the first workstation remains retracted according to the qualified instruction, and the slider 11 remains biased to the left side of the vehicle 1;

[0029] Subsequently, the vehicle 1 continues to be conveyed on the conveying device 2 and passes through the second workstation. The marking detection device 3 arranged at the second workstation detects that the slider 11 does not deviate to the right side of the vehicle 1. According to this instruction, the second workstation can operate on the components on the vehicle 1. After the operation of the second workstation is completed, the workstation detection device of this workstation detects that the operation of this workstation is unqualified. The push block 41 arranged at the second workstation extends according to the unqualified instruction and pushes the slider 11 to slide to the right side of the vehicle 1;

[0030] Subsequently, the vehicle 1 continues to be conveyed on the conveying device 2 and passes through the third workstation. The third marking detection device arranged at the third workstation detects that the slider 11 deviates to the right side of the vehicle 1. Then, according to this instruction, the third workstation cannot operate on the components on the vehicle 1. The third workstation will skip this vehicle 1 and not perform any operation on the components on it. The vehicle 1 continues to be conveyed on the conveying device 2 and passes through the fourth workstation, the fifth workstation, the sixth workstation...

[0031] When the marking detection devices at all workstations detect that the slider 11 deviates to the right side of the vehicle 1, this vehicle 1 will be skipped and no operation will be performed on the components on it. The vehicle 1 continues to be conveyed to the blanking workstation. When the vehicle 1 passes through the blanking workstation and the marking detection device at the blanking workstation monitors that the slider 11 deviates to the right side of the vehicle 1, the components on the vehicle 1 are clamped into the defective product box and dropped;

[0032] Subsequently, the vehicle 1 continues to be conveyed until the end of the conveying device 2. The vehicle 1 passes through the reset device 5. The reset device 5 pushes the slider 11 to slide back from the right side of the vehicle 1 to the left side of the vehicle 1 to achieve reset, which is convenient for circulating on the conveying device 2 and passing through the first workstation, the second workstation, the third workstation... again
