Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of docking machines, and particularly relates to a docking conveying mechanism. BACKGROUND

[0002] At present, automatic production mainly adopts a production line mode for processing, or adopts a high-integration device, adopts the production line mode for processing, and how to better and reasonably connect between devices is a problem in the prior art. In a large processing process, a mechanical hand is mostly used to grab a product from one process to another process. This way not only requires the accuracy of the positioning of the mechanical hand, but also the moving speed of the mechanical hand is slow, which can easily cause product accumulation. Meanwhile, the structure of the mechanical hand is relatively complex, and the maintenance cost is high. Before a server circuit mainboard is shipped, a series of functional tests need to be performed. The server circuit mainboard is connected to a test machine through the conveying effect of a moving mechanism, so as to complete data transmission. Chinese patent CN114132669A discloses a lift for docking a tray. The conveying part adopts conveying rollers and a speed chain for conveying. The conveying process is stable, and the transition transfer between two shipping lines can be easily realized, so as to complete the putting-in and taking-out operations. The feeding and discharging in the whole process are completed through the conveying rollers and other power sources, which consumes a large amount of energy and is difficult to ensure accurate positioning. Therefore, it is necessary to provide a docking conveying mechanism with compact structure and small energy consumption. SUMMARY

[0003] The technical problem to be solved by the application is to overcome the shortcomings of the prior art, and to provide a docking conveying mechanism with compact structure and small energy consumption.

[0004] The technical scheme adopted by the application is as follows: the application comprises a rack, a belt conveying line is arranged on the rack, a first driving cylinder is fixed to the inner side of the belt conveying line, a guide rail frame is connected to the action end of the first driving cylinder, a push-pull module is connected to the inner side of the guide rail frame, the push-pull module comprises a second driving cylinder, a connecting block, a U-shaped block, a connecting shaft and a protruding block, the second driving cylinder and the connecting block are both fixed to the guide rail frame, the output shaft of the second driving cylinder is in transmission connection with the U-shaped block, the U-shaped block slides in the connecting block, inclined grooves are symmetrically arranged on the plane ends on both sides of the U-shaped block, the connecting block is provided with a vertical through hole, the protruding block is located in the through hole, the connecting shaft passes through the protruding block, and both ends of the connecting shaft are in sliding connection with the inclined grooves, and the protruding block is located at a position of one-half to one-fourth of the length of the belt conveying line away from the discharging end.

[0005] It can be seen from the above scheme that the feeding end of the docking conveying mechanism cooperates with the external AGV, the discharging end of the docking conveying mechanism cooperates with the external testing machine, the docking conveying mechanism serves as a conveying mechanism for the product, the frame is connected to the action end of the external lifting platform, the belt conveyor line is used to convey the product to the top of the push-pull module, the push-pull module is used to convey the product to the port of the external testing machine, and the guide rail frame serves as a carrier for the product.

[0006] The external AGV transports the product to the feeding end of the connecting conveyor mechanism, and the belt conveyor line transports the product forward. When half the length of the product is still on the belt conveyor line, the belt conveyor line cannot continue to transport the product due to resistance. The traditional solution is usually to add a driving mechanism near the discharge end of the connecting conveyor mechanism, and drag the product in through the driving mechanism. This method is not conducive to the precise positioning of the product, and the external testing machine has limited activity space, which is not conducive to subsequent maintenance. If the entire process is loaded by an external robot, it will bring about the problem of high equipment cost. However, the push-pull module is arranged on the inner side of the guide rail frame and is an integrated structure with the connecting conveyor mechanism. The conveying length of the belt conveyor line is adapted to the product length, and the protrusion is located at half to quarter of the distance from the discharge end of the belt conveyor line. At a position of one-fifth of the length, the inclined groove is arranged on the U-shaped block along a certain slope, the connecting shaft passes through the protrusion and slides with the inclined groove, the driving cylinder is in an extended state in the initial state, and the second driving cylinder pulls back the U-shaped block. Since the connecting shaft passes through the protrusion and slides with the inclined groove, the U-shaped block slides in the connecting block, and the protrusion is located in the through hole, and the through hole limits the movement of the protrusion. The connecting shaft moves backward in the inclined groove, thereby driving the protrusion to move upward in the through hole, and the protrusion cooperates with the limiting hole of the product to clamp the product. The guide rail frame slides on several of the sliders driven by the first driving cylinder, and the product is separated from the belt conveyor line. The product is tested for conductivity with the external testing machine, thereby completing the connection and loading of the product.

[0007] Traditional push-pull modules are usually cylinders arranged on both sides of the belt conveyor line. Two groups of cylinders drive forward to clamp the product. The use of two groups of cylinders obviously increases the cost of the equipment. Since the two groups of cylinders apply force on both sides of the cylinder movement direction, when the product moves quickly, the product is prone to shifting, thereby affecting the positioning accuracy. Compared with other push-pull modules, the connecting conveying mechanism described in this application has a compact structure and consumes less energy.

[0008] A preferred solution is that a plurality of sliders are fixed on the inner side of the belt conveyor line, and the guide rail frame is slidably arranged on the plurality of sliders.

[0009] It can be seen from the above solution that the plurality of sliders serve as support bodies for the movement of the guide rail frame, thereby ensuring the sliding effect of the guide rail frame.

[0010] A preferred solution is that the connecting conveying mechanism also includes a first stop module and a second stop module, both of which are arranged on the frame, the first stop module is arranged at the feed end of the belt conveyor line, and the second stop module is arranged at the discharge end of the belt conveyor line, the first stop module and the second stop module both include a third driving cylinder and a stop block, and the stop block is transmission-connected to the output end of the third driving cylinder.

[0011] It can be seen from the above scheme that the first stop module is arranged at the feeding end of the belt conveyor line. When the belt conveyor line is conveying products, the third driving cylinder and the block in the first stop module cooperate to block the loading of the external AGV; the second stop module is arranged at the discharging end of the belt conveyor line. When the frame is lifting, the third driving cylinder and the block in the second stop module cooperate to block the loading of the belt conveyor line, thereby avoiding product accumulation.

[0012] A preferred solution is that the connecting and conveying mechanism also includes a guide module, and the guide module includes a fourth driving cylinder and a first guide plate respectively arranged on both sides of the belt conveyor line, and the output shaft of the fourth driving cylinder is connected to the second guide plate, and the first guide plate cooperates with the second guide plate.

[0013] It can be seen from the above scheme that when the product is transported to the top of the push-pull module, the fourth drive cylinder drives the second guide plate forward, and the first guide plate cooperates with the second guide plate to clamp and guide the product to ensure that the push-pull module and the product are accurately positioned.

[0014] A preferred solution is that the docking and conveying mechanism also includes a first pressure-proof collision module and a second pressure-proof collision module, and the first pressure-proof collision module and the second pressure-proof collision module both include a fixed block, a compression spring, a transmission shaft, a sensor plate and a first sensor, the fixed block is connected to the frame, the transmission shaft and the first sensor are arranged on the fixed block, the compression spring is sleeved on the transmission shaft, the sensor plate is connected to the end of the transmission shaft, the sensor plate cooperates with the first sensor electrical signal, the first pressure-proof collision module is pressed against the top of the frame, and the second pressure-proof collision module is pressed against the bottom of the frame.

[0015] It can be seen from the above scheme that the first pressure-proof collision module is pressed into engagement with the top of the frame, and the second pressure-proof collision module is pressed into engagement with the bottom of the frame. The compression spring is sleeved on the transmission shaft, and the compression spring is used to reset the transmission shaft. When the transmission shaft contacts a foreign object, the transmission shaft drives the sensor plate to move, and the sensor plate enters the sensing range of the first sensor. The connecting and conveying mechanism automatically alarms and stops, which can effectively ensure the safety of the operator.

[0016] A preferred solution is that the docking and conveying mechanism further includes a second sensor, which is arranged on one side of the push-pull module and cooperates with the electrical signal of the docking and conveying mechanism.

[0017] As can be seen from the above solution, the second sensor is used to sense whether the product has landed at the correct position. The second sensor cooperates with the electrical signal of the connecting and conveying mechanism to drive the push-pull module to start working.

[0018] A preferred solution is that the docking and conveying mechanism further includes an emergency button, which is arranged at the front end of the frame, and the emergency button cooperates with the electrical signal of the docking and conveying mechanism.

[0019] As can be seen from the above solution, when products pile up or the machine jams in an emergency, the operator presses the emergency button and the connecting conveying mechanism stops all actions, waiting for the operator to resolve the abnormality. BRIEF DESCRIPTION OF THE DRAWINGS
