Description

TECHNICAL FIELD

[0001] The present application relates to the field of automation production, in particular to a standardized tray automatic circulation feeding and storing device and its automatic circulation feeding and storing process for automatic feeding and material assembling in an automatic production line. BACKGROUND

[0002] Automation is to replace manual work with machines to complete various production and processing. In the field of automation equipment, since the production products are generally composed of multiple scattered parts, in the actual production process, various parts need to be automatically assembled by equipment to form a complete product structure. Therefore, the automatic assembling of various materials is a common production process, which is applied in many fields, such as various intelligent terminal devices, mobile phones, tablet computers, smart watches, batteries, power supplies, and various daily products, toys, etc. all have the production demand of automatic material assembly. Since the types and specifications of materials in the automatic assembly process are different, the existing automatic assembly technology generally uses separate assembly equipment for different materials, which is difficult to form a standardized and universal assembly equipment.

[0003] For the automatic assembly of materials, different materials need to be assembled, so it involves the assembled materials (such as various electronic components) and the base material (such as PCB board). Therefore, the automatic assembly process of materials as a whole includes three process sections, namely the automatic feeding process of the assembled materials, the feeding process of the base material, and the automatic assembly process of the assembled materials and the base material.

[0004] For the feeding process of the assembled materials, the existing automatic feeding process includes vibration disc feeding, material belt feeding, Tray feeding, etc. Different feeding methods are selected according to different specifications of materials. Tray, also known as material tray, is a mechanism for loading materials. In the process of assembly, processing, and detection, the material tray is used to carry the assembled materials. Generally, a single material tray can carry multiple materials, and to ensure continuous feeding, multiple material trays are stacked together for overall feeding. The traditional material tray feeding technology is to manually carry the material tray loaded with materials to the material taking station, take the materials from the material taking station after the materials are taken, and then place a new full material tray. This kind of material tray feeding method has low production efficiency and cannot meet the production capacity demand of modern automatic production lines. Therefore, to improve the efficiency of material tray feeding, the technical problems to be solved include automatic feeding of multiple stacked material trays, taking of material tray, taking of materials, and empty material tray circulation storing and feeding.

[0005] The feeding process of the substrate material generally uses a jig as a device carrier. After the jig clamps the substrate material, the substrate material is transported to the assembly station, and the assembled material is taken out by the assembly robot and automatically assembled onto the substrate material. After the traditional jig clamps the substrate material, it is generally directly transported to the assembly station of the production line by the transportation mechanism. The assembly robot assembles the material onto the substrate material. After assembly is completed, the jig moves the substrate material to the next station until the material assembly is completed. The technical problem is that a complex positioning mechanism is needed to block and position the moving jig at the assembly station. In addition, after the material assembly on the jig is completed, the jig needs to be removed from the tail end of the substrate material, and then the next substrate material is reloaded. The jig cannot be automatically circulated and transported, and a large amount of time is consumed when the jig is taken out and put in, resulting in low production efficiency. In addition, for the single-track transmission jig, the jig is freely embedded on the slide rail, and the transmission belt is arranged on one side of the slide rail. The jig is driven forward by the static friction force between the jig and the transmission belt. For this transmission method, after the jig is positioned, since there are many stations on the entire production line, the transmission belt needs to be continuously transmitted forward. During the assembly process of a single station, the jig needs to be positioned while being separated from the transmission belt to prevent continuous friction between the moving transmission belt and the bottom of the positioned jig. Therefore, the jig positioning mechanism needs to be redesigned to meet the above process requirements. SUMMARY

[0036] The application takes a machine base as a bearing platform, and a plurality of standardized mounting stations are arranged on the machine base in parallel. A material taking part is detachably arranged on the mounting station. An upper material loading part is arranged on one side of the material taking part, and a processing platform is arranged on the other side of the material taking part. The processing platform takes a conveying slide rail as a carrier, and a plurality of assembly stations are arranged on the conveying slide rail at intervals corresponding to the mounting stations. A jig is taken as a base material bearing structure, and the jig is slidably embedded on the conveying slide rail and is pressed against a conveying belt arranged on one side of the conveying slide rail by its own gravity. When the conveying belt moves linearly, the jig is driven to move along the conveying slide rail at each assembly station, so as to transport the base material to each assembly station. The material taking part of the application takes a sliding support as a bearing structure, and an assembly robot is detachably arranged on the top of the sliding support as a material taking execution component. In particular, the upper material loading part of the application includes two layers of bearing planes, and the two layers of bearing planes are respectively horizontally extended into the sliding support. The lower layer of bearing planes is sequentially provided with an upper material loading station and a lifting station from outside to inside, and the upper layer of bearing planes is sequentially provided with a disc storage station and a material taking station from outside to inside. A plurality of stacked material discs are placed on the upper material loading station, and the material discs are transported from the upper material loading station to the lifting station by a horizontal transmission mechanism. A lifting mechanism arranged at the lifting station passes through the horizontal transmission mechanism from the lower layer to the upper layer to lift the stacked material discs upward to below the disc taking mechanism arranged on both sides of the lifting mechanism. The disc taking mechanism drives the material discs to move to above the material taking station after the material discs are sucked from both sides of the lifting station from the uppermost layer. A disc carrier unloaded with empty material discs at the disc storage station is horizontally moved to the material taking station on the upper layer of bearing planes. At this time, a disc taking suction nozzle of the disc taking mechanism arranged above the material taking station and a disc taking plug arranged downward are synchronously moved downward by a power drive.

After the disc carrier is opened, the disc taking suction nozzle places the material disc on the disc carrier. After the disc taking plug is pulled out from the gap space between the dolly wheel and the carrier plate limiting strip, the carrier plate limiting strip is automatically clamped inward beyond the rebound force of the limiting spring. An assembly robot arranged above the material taking station continuously takes material from the clamped material disc to be assembled on the base material on the jig at the assembly station. After the material disc is completely taken, the disc carrier drives the empty material disc to move to the disc storage station. The application creatively designs a disc lifting mechanism and a disc receiving bearing mechanism at the disc storage station. The disc lifting mechanism extends upward along both sides of the disc storage station, and the disc receiving bearing mechanism is arranged on the inner side of the disc lifting mechanism and above the disc storage station. After the disc carrier drives the empty material disc to move to the disc storage station, a disc inserting rod of the disc lifting mechanism passes through the gap space between the dolly wheel and the carrier plate limiting strip of the disc carrier upward, and a slope at the top of the disc inserting rod horizontally pushes the dolly wheel to make the carrier plate limiting strip move linearly outward, so as to loosen the empty material disc. A disc lifting column of the disc lifting mechanism passes through the disc carrier from below to press against the material disc and drive the material disc to move upward away from the disc carrier.Meanwhile, the tray moves upwards through the upper tray bearing mechanism, and the tray bearing block of the tray bearing mechanism is pushed outwards, the tray bearing block compresses the reset spring, and after the tray moves above the tray bearing block, the tray bearing block returns to the horizontal plane under the rebound force of the reset spring, the top disc column moves downwards to place the empty tray on the tray bearing block, thereby realizing the storage of the empty tray.

In the natural state, the elastic force of the return spring 85 pushes the tray rotating block 84 to rotate inwardly, forming a horizontal support surface to support the tray. When the top tray column 78 drives the tray to move upwardly, the tray pushes the tray rotating block 84 from bottom to top, and the tray rotating block 84 rotates outwardly to move the tray above the tray rotating block 84. Then, the tray rotating block 84 rotates to the horizontal state under the elastic force of the return spring 85, and the top tray column 78 places the tray on the tray rotating block 84 in the horizontal state.

At least two inwardly recessed side grooves are formed in the side walls of the base 101 and the jig carrier 102, respectively. The side grooves of the base 101 and the jig carrier 102 are arranged in a corresponding inclined upward manner from bottom to top, and the side grooves of the base 101 extend horizontally along the side edges of the base 101. The limiting swing block 103 comprises at least two limiting swing blocks 103, which are embedded between the side grooves of the base 101 and the jig carrier 102, and the upper and lower ends of the limiting swing block 103 are rotatably arranged in the side grooves of the base 101 and the jig carrier 102, respectively. The first roller 105 and the second roller 106 are arranged in a spaced apart manner on the side wall of the base 101 in a direction opposite to the jig 10, and are rotatably connected with the side wall of the base 101, respectively. The sliding seat 107 is arranged at the bottom of the base 101, and is slidably embedded on the conveying slide rail 9. The bottom of the base 101 presses a conveying belt arranged on one side of the conveying slide rail 9. The conveying belt drives the jig to move linearly along the conveying slide rail 9 through static friction, and the conveying slide rail 9 guides and limits the jig.

[0105] The jig positioning mechanism 11 comprises a positioning support 111, a positioning cylinder 112, a positioning sliding seat 113, a positioning connecting block 114, a positioning spring 115, a first inclined lifting block 116, a second inclined lifting block 117, a blocking support 118 and a blocking column 119. The positioning support 111 is vertically arranged on the side of the conveying sliding rail 9. The positioning cylinder 112 is vertically arranged on one side of the positioning support 111, and the output end is arranged downward. The positioning sliding seat 113 is slidably connected to the other side wall of the positioning support 111 in the vertical direction. One end of the positioning connecting block 114 is connected to the output end of the positioning cylinder 112, and the other end of the positioning connecting block 114 extends horizontally through the positioning support 111 to the other side of the positioning support 111 and is connected with the positioning sliding seat 113. The positioning cylinder 112 drives the positioning sliding seat 113 to move up and down through the positioning connecting block 114. The positioning spring 115 is vertically arranged, and the lower end of the positioning spring 115 is connected to the positioning sliding seat 113 and extends vertically upward. The first inclined lifting block 116 and the second inclined lifting block 117 are arranged on the top and the outer side wall of the positioning sliding seat 113 respectively. The first inclined lifting block 116 is vertically connected to the upper end of the positioning spring 115. The top of the first inclined lifting block 116 and the second inclined lifting block 117 is respectively provided with a first inclined surface and a second inclined surface. The first inclined surface extends upwardly and obliquely along the movement direction of the jig 10. The second inclined surface extends obliquely in the opposite direction of the first inclined surface. The top end of the first inclined surface is provided with a positioning groove recessed inward. The inner diameter of the positioning groove is not less than the outer diameter of the first roller 105. The blocking support 118 is arranged on the side wall of the positioning sliding seat 113 close to the movement direction of the jig 10 and extends vertically upward. The blocking column 109 is arranged on the upper part of the blocking support 108 and extends horizontally toward the opposite direction of the jig 10. When the jig 10 moves linearly to the jig positioning mechanism 11, the blocking column 109 blocks the jig carrier 102 of the upper layer of the jig. Due to the inertia effect, the base 101 of the lower layer of the jig continues to drive the first roller 105 and the second roller 106 to move along the first inclined surface and the second inclined surface of the first inclined lifting block 116 and the second inclined lifting block 117 respectively. The force of the first roller 105 on the first inclined surface compresses the positioning spring 115 downward, so that the first inclined lifting block 116 descends. When the first roller 105 moves to the top end of the first inclined surface and slides into the positioning groove, the rebound force of the positioning spring 115 pushes the first inclined lifting block 116 upward. The first inclined lifting block 116 drives the second inclined lifting block 117 to lift the second roller 106 upward. The upward force of the second roller 106 on the base 101 overcomes the elastic force of the connecting spring 104 to make the base 101 lift upward, so that the bottom of the base 101 is separated from the conveying belt on one side of the conveying sliding rail 109. The static friction force between the conveying belt and the base 101 is disabled. The distance between the base 101 and the jig carrier 102 is reduced, and the limiting swing lever 103 rotates gradually toward the horizontal direction.

[0106] A standardized tray automatic circulation feeding and storing process of a processing device, comprising the following steps:

[0107] S1, feeding: a plurality of material trays filled with materials are stacked and placed at the feeding station of the horizontal transmission mechanism of the feeding part, and are linearly transmitted to the lifting station by the horizontal transmission mechanism;

According to different product requirements, the corresponding structure can be assembled, which greatly improves the generalization of automatic assembly, and the standardized tray automatic circulation feeding and storage processing device and the automatic circulation feeding and storage processing technology have good market value.

[0121] The application takes a machine base as a bearing platform, and a plurality of standardized mounting stations are arranged on the machine base in parallel. A material taking part is detachably arranged on the mounting station. An upper material loading part is arranged on one side of the material taking part, and a processing platform is arranged on the other side of the material taking part. The processing platform takes a conveying slide rail as a carrier, and a plurality of assembly stations are arranged on the conveying slide rail at intervals corresponding to the mounting stations. A jig is taken as a base material bearing structure, and the jig is slidably embedded on the conveying slide rail and is pressed against a conveying belt arranged on one side of the conveying slide rail by its own gravity. When the conveying belt moves linearly, the jig is driven to move along the conveying slide rail at each assembly station, so as to transport the base material to each assembly station. The material taking part of the application takes a sliding support as a bearing structure, and an assembly robot is detachably arranged on the top of the sliding support as a material taking execution component. In particular, the upper material loading part of the application includes two layers of bearing planes, and the two layers of bearing planes are respectively horizontally extended into the sliding support. The lower layer of bearing planes is sequentially provided with an upper material loading station and a lifting station from outside to inside, and the upper layer of bearing planes is sequentially provided with a disc storage station and a material taking station from outside to inside. A plurality of stacked material discs are placed on the upper material loading station, and the material discs are transported from the upper material loading station to the lifting station by a horizontal transmission mechanism. A lifting mechanism arranged at the lifting station passes through the horizontal transmission mechanism from the lower layer to the upper layer to lift the stacked material discs upward to below the disc taking mechanism arranged on both sides of the lifting mechanism. The disc taking mechanism drives the material discs to move to above the material taking station after the material discs are sucked from both sides of the lifting station from the uppermost layer. A disc carrier unloaded with empty material discs at the disc storage station is horizontally moved to the material taking station on the upper layer of bearing planes. At this time, a disc taking suction nozzle of the disc taking mechanism arranged above the material taking station and a disc taking plug arranged downward are synchronously moved downward by a power drive. The disc taking plug is first inserted into a gap space between a dolly wheel and a carrier plate limiting strip of the disc carrier, and the disc taking plug horizontally pushes the dolly wheel by a slope at the bottom of the disc taking plug to drive the carrier plate limiting strip to be pushed outward beyond the elastic force of a limiting spring, so as to open the disc carrier. After the disc carrier is opened, the disc taking suction nozzle places the material disc on the disc carrier. After the disc taking plug is pulled out from the gap space between the dolly wheel and the carrier plate limiting strip, the carrier plate limiting strip is automatically clamped inward beyond the rebound force of the limiting spring. An assembly robot arranged above the material taking station continuously takes material from the clamped material disc to be assembled on the base material on the jig at the assembly station. After the material disc is completely taken, the disc carrier drives the empty material disc to move to the disc storage station. The application creatively designs a disc lifting mechanism and a disc receiving bearing mechanism at the disc storage station. The disc lifting mechanism extends upward along both sides of the disc storage station, and the disc receiving bearing mechanism is arranged on the inner side of the disc lifting mechanism and above the disc storage station. After the disc carrier drives the empty material disc to move to the disc storage station, a disc inserting rod of the disc lifting mechanism passes through the gap space between the dolly wheel and the carrier plate limiting strip of the disc carrier upward, and a slope at the top of the disc inserting rod horizontally pushes the dolly wheel to make the carrier plate limiting strip move linearly outward, so as to loosen the empty material disc. A disc lifting column of the disc lifting mechanism passes through the disc carrier from below to press against the material disc and drive the material disc to move upward away from the disc carrier.Meanwhile, the tray moves upwards through the upper tray bearing mechanism, and the tray bearing block of the tray bearing mechanism is pushed outwards, the tray bearing block compresses the reset spring, and after the tray moves above the tray bearing block, the tray bearing block returns to the horizontal plane under the rebound force of the reset spring, the top disc column moves downwards to place the empty tray on the tray bearing block, thereby realizing the storage of the empty tray. The tray forms a rectangular circulating flow path between the feeding station, the lifting station, the taking station and the storage station, realizes efficient connection with the taking action, effectively shortens the tray feeding, transportation and storage time, and improves the production capacity.

[0122] The processing platform part is designed creatively, the processing platform takes the machine table as a bearing structure, the machine table includes upper and lower horizontal support platforms, a linearly arranged conveying slide rail is taken as a jig conveying carrier, a material assembly processing line is formed on the upper layer of the machine table, and a plurality of mounting stations are arranged on the assembly processing line at intervals.

[0123] Particularly, the jig is designed as a double-layer structure, the lower layer is a base, the upper layer is a jig carrier, the base and the jig carrier are connected through connecting springs, side grooves are respectively formed in the base and the jig carrier, the side grooves of the base and the jig carrier are arranged in an inclined direction, a limiting swing block is embedded between the side grooves of the base and the jig carrier, the two ends of the limiting swing block are rotatably connected in the side grooves, the limiting swing block ensures that the base and the jig carrier are connected together, the connection realizes the adjustable state of the distance between the base and the jig carrier and the relative position of the base and the jig carrier in the horizontal direction, and the connecting spring cooperates to form elastic support. One side of the base is connected with a sliding seat, the sliding seat is embedded on the conveying slide rail, the bottom of the base is provided with a contact layer to contact the conveying belt on one side of the conveying slide rail. In addition, the side of the base is also provided with a first roller and a second roller at intervals, and the first roller and the second roller are rotatably connected to the side wall of the base.

[0124] The jig positioning mechanism of the present application is vertically arranged and used as a bearing structure, and only includes one power output component, i.e. a positioning cylinder, which drives the positioning slide to move up and down. In the structural design, the positioning cylinder and the positioning slide are vertically arranged on the two sides of the positioning support, and the output end of the positioning cylinder and the positioning slide are connected through the positioning connecting block penetrating the positioning support from the bottom, so as to effectively utilize the space and reduce the overall space occupancy. In particular, the first inclined top block is connected with the positioning spring arranged vertically on the top of the positioning slide, and the internal stress of the positioning spring is greater than that of the connecting spring of the jig. The second inclined top block is connected with the side wall of the first inclined top block, and the blocking pillar is connected with the end wall of the positioning slide. The top of the first inclined top block and the second inclined top block is respectively provided with the first inclined surface and the second inclined surface with opposite inclined directions, wherein the top of the first inclined surface is provided with the positioning groove recessed downward, and the width of the positioning groove is greater than the outer diameter of the first roller. The blocking support extends upward in the vertical direction to above the first inclined top block, and the horizontal blocking column is arranged on the side wall of the blocking support close to the first inclined top block. When the jig moves to the jig positioning mechanism, the blocking column blocks the jig carrier on the upper layer of the jig, and the jig carrier stops moving. The lower layer of the jig base continues to move forward due to inertia. At this time, the first roller slides upward along the first inclined surface, the first inclined top block presses the positioning spring downward, and the first roller falls into the positioning groove when the first roller slides to the top of the first inclined surface. At this time, the first inclined top block loses the downward pressure of the first roller, the rebounding force of the positioning spring pushes the second inclined top block upward, the second inclined surface on the top of the second inclined top block abuts against the second roller of the jig, and the second roller is lifted upward, the second roller drives the base to move upward to overcome the internal stress of the connecting spring, so as to realize the separation of the bottom of the base from the conveying belt. When the base moves upward, the spacing between the base and the jig carrier is shortened through the flexible connection of the limiting swing block. Through the above structural design, the lifting of the jig is completed at the same time of blocking the movement of the jig through one power output, so that the transmission between the jig and the conveying belt is invalid, so as to facilitate the assembly and processing.
