Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a schematic structural diagram of a cooling docking apparatus according to an embodiment of the present invention, which is used as a docking apparatus and is used for cooling a high-temperature electronic product and outputting the cooled electronic product to a post-production station. For example, the cooling connection equipment can be applied to the output end of a reflow soldering furnace to cool the high-temperature circuit board output by the reflow soldering furnace, and the cooled circuit board is output to the detection equipment, so that automatic cooling and automatic transmission are realized, and the production efficiency is improved. Referring to fig. 1, the cooling docking apparatus includes: a first rail 110 and a second rail 120 disposed side by side, the first rail 110 being spaced apart from the second rail 120 by a predetermined distance to form a cooling passage 130 between the first rail 110 and the second rail 120;
the opposite sides of the first rail 110 and the second rail 120 are provided with transmission mechanisms, and the transmission mechanisms at the two sides are matched to output the cooled device to a receiving device.
The device to be cooled is a high-temperature product output by a front production station, and when the device is a hard product, the high-temperature product is the device per se; when the device is a flexible device which cannot be self-supported, such as an FPC (flexible printed circuit), the high-temperature product comprises the device and a carrier for supporting the device.
The first rail 110 and the second rail 120 are arranged along the conveying direction, a cooling passage 130 is formed between the two rails, a cooling device 140 is arranged in the cooling passage 130, and when the high-temperature product passes through the cooling passage 130, the cooling device 140 can spray cold air from below the high-temperature product to the high-temperature product so as to cool the high-temperature product.
The arrangement number of the refrigeration equipment 140 is adjusted according to the size of the cooling channel 130, so that enough cold air is generated through the combination of the refrigeration equipment 140, and the high-temperature product is rapidly cooled to a preset temperature. For example, a plurality of refrigeration devices 140 may be arranged along the conveying direction, so that when a high-temperature product is conveyed, the refrigeration devices 140 always spray cold air to the high-temperature product, which is equivalent to prolonging the cooling time of the high-temperature product, and ensuring that the high-temperature product is sufficiently cooled in the cooling channel until the preset temperature is reached. The preset temperature may be, for example, 35 ℃ or room temperature below 35 ℃. Therefore, because the temperature of the product is greatly reduced, when the worker needs to contact the product, the worker can operate without wearing high-temperature-resistant gloves, the worker can conveniently operate, and the worker cannot be injured, so that the worker can be prevented from being injured at high temperature, and production accidents are avoided.
The refrigeration apparatus 140 may be a refrigeration apparatus 140 that self-generates a cold source, for example, a vortex refrigerator that generates cold air at an adjustable pressure and sprays the cold air through a nozzle to a hot product. Or the cooling device 140 may provide a cold source and a gas from the outside, for example, cooling water may be injected from the outside to cool the injected gas to form cold air, and the cooling device 140 may spray the cold air to the high-temperature product according to a certain pressure.
The pressure of the cold air generated by the refrigerating equipment 140 can be adjusted, so that the cold air can act on the surface of a high-temperature product, the cooling effect is improved, meanwhile, the high-temperature product cannot be damaged, and therefore the cooling connection equipment can be used for cooling electronic products of different types, and the applicability of the cooling connection equipment is improved.
The first rail 110 and the second rail 120 are both provided with transmission mechanisms, the transmission mechanisms on the two sides are matched to receive the high-temperature product on the front production station, and the cooled product is output to the receiving equipment on the rear production station, so that the connection function of the cooling and connecting equipment is realized.
According to the cooling connection device provided by the embodiment of the invention, the refrigeration device 140 is arranged through the cooling channel 130 formed between the two rails, the refrigeration device 140 generates cold air with a certain pressure, and the refrigeration device 140 sprays the cold air to a high-temperature product to quickly reduce the temperature of the high-temperature product to the preset temperature. The transmission mechanisms are respectively arranged on the two rails, and the transmission mechanisms on the two sides receive the high-temperature products and output the cooled products to the post-production station to continue the production flow, so that the function of conveying the products is realized. The cooling connection equipment provided by the embodiment of the invention can cool a high-temperature product before a detection process, solves the problem that the optical performance of the product is affected by high temperature due to direct detection of the high-temperature product in the prior art, and can automatically output the cooled product to subsequent equipment, thereby ensuring the uninterrupted execution of a production flow and improving the automation degree and the production efficiency of production; and because the temperature of the product is greatly reduced, when manual operation is needed, the cooled product can not cause injury to personnel, so that the probability of injury of the personnel due to high temperature is reduced, and production accidents are avoided.
Optionally, on the basis of the above embodiment, reference is continued to fig. 1. Each of the cooling apparatuses 140 includes more than one cool air injection portions 142, and the cool air injection portions 142 are spaced apart in the same direction on the body of the cooling apparatus 140;
each of the cooling devices 140 has a predetermined angle between the arrangement direction of the cooling passage 130 and the arrangement direction of each of the cold air spraying portions 142, so that the cold air sprayed from each of the cooling devices 140 fills the cooling passage 130.
Wherein each of the cooling devices 140 includes a plurality of the cool air injection portions 142 so that a single cooling device 140 can inject more cool air, whereby the cooling efficiency of a single cooling device 140 can be improved, which contributes to a reduction in the number of the arrangement of the cooling devices 140.
A plurality of cooling devices 140 may be disposed in the cooling passage 130, so that the high-temperature product is always sprayed with cold air during the transportation of the cooling passage 130, i.e., the high-temperature product can be continuously cooled. This can rapidly lower the temperature of the high-temperature product to a preset temperature.
The arrangement direction of the plurality of cooling devices 140 and the arrangement direction of the cool air spraying part 142 form a predetermined angle to increase the cool air coverage area. For example, the respective cold air spraying portions 142 of the single cooling device 140 are arranged in the width direction of the cooling passage 130, and the plurality of cooling devices 140 are arranged in the transport direction so that the cold air can fill the cooling passage 130, so that the high-temperature product can be continuously temperature-reduced before exiting the cooling passage 130.
Optionally, on the basis of the above embodiment, each of the refrigeration devices 140 includes an ion generator (not shown in fig. 1), and an ion output channel of the ion generator is communicated with the cold air spraying portion 142, so that the cold air spraying portion 142 outputs ion cold air.
Wherein, ion generator can continuously produce ion, and ion generator's ion output channel communicates cold air injection portion 142, and the ion that ion generator produced fuses with cold air and forms ion cold wind. The cold air injection part 142 blows the cold air of ions toward the high-temperature product, and the ions neutralize Static electricity in the environment, thereby improving an ESD (Electro-Static discharge) environment of the product, and contributing to reduction of damage of the product by the Static electricity.
In this embodiment, ions generated by the ion generator are output in an ion cold air mode, and compared with a traditional static elimination method for connecting a product with an ESD wire, the output ion cold air is more uniform and can be quickly neutralized with static electricity. In one embodiment, the neutralization time of the ions and static electricity may be less than 1s, and the residual voltage after neutralization is less than 5V.
Optionally, on the basis of the above embodiment, reference is continued to fig. 1. The cooling docking apparatus further includes a first controller 150 and an alarm 160 connected to the first controller 150;
the first controller 150 is used for detecting the transmission state of the device to be cooled and outputting an alarm trigger signal when the transmission state of the device to be cooled is determined to be abnormal;
the alarm 160 is configured to output an alarm signal in response to an alarm trigger signal.
The abnormal transportation state of the device to be cooled may be, for example, the device to be cooled is blocked or dropped and cannot be transported further. When the transmission is abnormal, on the one hand, the current product can be damaged, the product on the previous production station can not be normally output, more products are damaged, production accidents occur, and on the other hand, the equipment can also be damaged. Therefore, when the product is detected to have abnormal transmission, timely processing is needed.
In this embodiment, the first controller 150 is configured to detect the transmission state of the product, and when the first controller 150 detects that the transmission state of the product is abnormal, the first controller 150 outputs an alarm trigger signal to trigger the alarm 160 to alarm.
The alarm 160 is configured to perform an alarm alert in response to an alarm trigger signal of the first controller 150. The alarm mode can be an acoustic alarm and/or a luminous alarm and the like. For example, a buzzer alarm may be provided by a buzzer, and/or a light alarm may be provided by a light emitting diode. Therefore, the staff is reminded to process in time, and the transmission fault is eliminated in time.
In some embodiments, the first controller 150 sends a product signal capable of being sent to the receiving device in real time by communicating with the receiving device at the output end and the output device at the input end, or sends an acceptable product signal or suspends receiving the product signal to the output device in real time, if the number of times that the first controller 150 continuously sends the product signal capable of being sent reaches a set number of times and the receiving device still does not receive the product, or if the first controller 150 continuously sends the acceptable product signal for the set number of times and the output device does not output the product, or if the first controller 150 has sent the product signal capable of being received in suspension to the output device and the output device still outputs the product, the first controller 150 may trigger the alarm 160 to alarm.
This embodiment carries out real time monitoring through setting up first controller 150 to the transmission state of high temperature product, and when detecting the transmission state of product unusual, first controller 150 triggers alarm 160 and reports to the police and reminds to inform the staff with transmission fault very first time, the staff can in time handle the product of transmission unusual according to alarm signal, thereby can avoid more products to block up or drop because of transmitting unusually and lead to the product to scrap, improve the settlement yields of product. Meanwhile, because the products with abnormal transmission can be processed in time, the risk that the cooling and connecting equipment is damaged is correspondingly reduced.
Optionally, on the basis of the above embodiment, reference is continued to fig. 1. The cooling docking apparatus further includes a first signal sensor 171 and a second signal sensor 172 connected to the first controller 150, respectively;
the first signal sensor 171 is disposed at an input end of the cooling and docking apparatus, and is configured to output a first sensing signal when the device to be cooled enters the cooling and docking apparatus;
the second signal sensor 172 is disposed at an output end of the cooling docking apparatus, and is configured to output a second sensing signal when the cooled device leaves the cooling docking apparatus;
the first controller 150 is further configured to determine a transmission duration of the device to be cooled in the cooling docking apparatus based on the first sensing signal and the second sensing signal, and determine that the transmission state of the device to be cooled is abnormal when the transmission duration is greater than a preset duration threshold.
Here, the first signal sensor 171 and the second signal sensor 172 may be the same type of signal sensor. The signal sensor may detect whether a product passes through the detection area, for example, by emitting a detection signal to the detection area and based on a reflected signal of the detection signal. When detecting that a product passes through the detection area, a sensing signal is output to the first controller 150, so that the first controller 150 can determine the transmission time length of the product in the equipment according to the sensing signals output by the signal sensors at the input end and the output end. When the transmission time period is greater than the time period threshold value, the first controller 150 determines that the transmission state of the product is abnormal. For example, the time threshold is set to 40s, if the transmission time of a certain circuit board in the device exceeds 40s, the first controller 150 determines that the circuit board is abnormal in transmission, and at this time, the first controller 150 triggers the alarm 160 to alarm.
In some embodiments, a signal sensor may also be disposed in an intermediate position of the cooling and docking device, so as to detect an abnormal transmission state of the product more timely and monitor an operation state of the product more accurately.
In this embodiment, the signal sensors are respectively arranged at the input end and the output end of the cooling connection device, the signal sensors output sensing information to the first controller 150, the first controller 150 determines whether the product is abnormal in transmission according to the signal sensors at the two ends, and when it is determined that the product is abnormal in transmission, the alarm 160 is triggered to alarm and remind, so as to inform the staff of timely processing.
Optionally, fig. 2 is a schematic structural diagram of a transmission mechanism provided in an embodiment of the present invention. On the basis of the above embodiment, reference is made to fig. 2. The cooling docking apparatus further includes a second controller 210 and a first motor 220 connected to the second controller 210;

The second controller 210 and the first controller may be the same controller, and are used for monitoring the transmission state of the product and adjusting the transmission speed of the product.
The first motor 220 is disposed on one of the rails as a power source for the same-side transmission mechanism. As shown in fig. 2, taking the first motor 220 disposed on the first rail 110 as an example, the first motor 220 drives the transmission mechanism on the first rail 110 side to operate, and the transmission mechanism on the first rail 110 side is connected to the transmission mechanism on the second rail 120 side through a transmission shaft, so that the transmission mechanisms on both sides can be driven to operate synchronously by using only one motor.
The second controller 210 may communicate with the receiving device to obtain the receiving speed of the receiving device, and obviously, when the output of the product output by the cooling docking device is consistent with the receiving speed of the receiving device, the product may be output in order without the problem of product blockage, so that the normal circulation of the production line may be ensured by adjusting the output speed of the product in real time by the second controller 210 according to the receiving speed of the receiving device. The rotation speed of the first motor 220 corresponds to the transmission speed of the transmission mechanism, and the second controller 210 adjusts the rotation speed of the first motor 220 based on the correspondence, so that the output speed of the product is consistent with the receiving speed of the receiving device. Alternatively, when the receiving device cannot receive the product, the second controller 210 controls the first motor 220 to reduce the rotation speed or stop the operation to suspend the output of the product to the receiving device. In one embodiment, the second controller 210 controls the first motor 220 to achieve a speed range of 0-120 cm/min.
In some embodiments, the second controller 210 also communicates with the output device of the previous production station to feed back the current product delivery status to the high temperature product output device of the input. The advantage of this arrangement is that the second controller 210 notifies the output device of the current product running state in time, and can instruct the output device to adjust the speed of outputting the high-temperature product correspondingly, thereby avoiding the high-temperature product from being blocked in the cooling docking device and causing the product to be scrapped.
In this embodiment, the second controller 210 may perform communication with the front-end and back-end receiving devices and the output devices by a customized protocol, so as to improve compatibility between the devices.

And the transmission mechanisms on both sides are connected through a transmission shaft, so that the transmission mechanisms on both sides are synchronously operated under the driving of the first motor 220.
