Description

Technical Field

[0001] The invention relates to the field of injection molding production equipment, in particular to an automated processing production line for a gas meter valve cover. Background Art

[0002] In the structure of the gas meter, the valve cover is a component that uses its contact surface with the valve seat to move relative to each other in a predetermined manner, so that the gas enters and exits each metering chamber in a specified order. According to the basic requirements of the industry standard, there are clear requirements for the appearance, surface roughness, flatness, etc. of the valve cover, such as the performance indicators of the appearance: the machined surface should be smooth, without defects such as bubbles, peeling, burrs, etc. The grinding surface should be flat, without defects such as sand holes, looseness, cracks, lack of materials, impurities, etc.

[0003] When processing and producing valve covers, high requirements are placed on key processes such as valve cover molding and grinding. Molding mainly restricts the performance indicators of appearance, and grinding seriously restricts the performance indicators of valve cover flatness. Since the processed valve covers are in batches, based on the appearance requirements, high requirements are also placed on the storage and transportation of finished valve covers. Strong vibration, extrusion, collision, tumbling, moisture, heat, packaging damage, dust prevention, etc. should be avoided. Under these basic performance indicators of the products themselves, with the development of intelligence and automation, the requirements for increased production capacity also put forward higher requirements for the overall production efficiency of the product production line, such as the degree of automation, grinding efficiency per unit time, production line transportation efficiency, stacking efficiency, packaging effect, inspection efficiency of defective products, etc., which comprehensively affect the overall production efficiency of the production line.

[0004] With respect to the above-mentioned related technologies, in the valve cover production process, the valve cover is usually transported from one workstation to another by a conveyor belt, and a handling robot is provided at different workstations to carry the valve cover between different conveyor belts and workstations. In the process of the handling robot carrying the valve cover, in order to enable the handling robot to accurately grasp the valve cover, the valve cover needs to be accurately positioned, so a positioning workpiece adapted to the valve cover needs to be provided on the conveyor belt, and for different types of valve covers, the positioning workpieces provided on the conveyor belt are also different. When producing different types of valve covers, the positioning workpieces on the conveyor belt need to be adjusted, and many positioning workpieces are usually provided on a conveyor belt, so it takes a lot of time to adjust, affecting the production efficiency of the valve cover.

An injection molding machine is provided at the injection molding station 1, and the valve cover raw material is injection molded in the injection molding machine. The sprue folding station 2 is provided at the discharge end of the injection molding machine. A sprue folding machine is provided at the sprue folding station 2. After the valve cover is injection molded, the valve cover is removed from the injection molding machine by the handling robot, and the valve cover is placed in the sprue folding machine to remove the sprue.

[0031] The conveyor belt 8 at the tail end of the folding water outlet station 2 is set as a conveying branch line, and a conveying main line is provided at the tail end of the conveying branch line. The deburring station 3 is set at the tail end of the conveying main line. The injection molding machine, the folding water outlet machine and the conveying branch line are all provided with multiple groups. In this embodiment, three groups of conveying branch lines are used as an example for explanation. A roller deburring mechanism is provided at the deburring station 3, and the valve cover on the conveying main line is transported to the roller deburring mechanism by a handling manipulator for deburring.

[0032] The conveyor belt 8 at the tail end of the roller deburring mechanism is set as a deburring conveyor line, through which the valve cover in the roller deburring mechanism is removed and the valve cover is conveyed to the baking station 4. A baking machine is provided at the baking station 4, and a bracket is provided in the baking machine, and the bracket reciprocates along the length direction of the baking machine. The conveyor belt 8 at the beginning of the baking machine is set as a pre-baking conveyor line. When the valve cover approaches the baking machine along the deburring conveyor line, the valve cover is moved to the pre-baking conveyor line by the handling manipulator.

[0033] The pre-baking conveyor line conveys the valve cover to the baking machine. A baking tray is placed at the end of the pre-baking conveyor line near the baking machine. The valve cover is moved one by one from the pre-baking conveyor line to the baking tray by a handling robot, and the baking tray filled with valve covers is stacked on the bracket. After the stacking is completed, the bracket drives the baking tray to move along the length direction of the baking machine, so that the baking machine bakes the valve cover.

[0034] The pre-grinding swing station 51 is located at the tail end of the baking station 4. A hoist is provided at the pre-grinding swing station 51. The hoist is provided with a material bin. The handling manipulator at the tail end of the baking machine is provided with a dumping mechanism. When the bracket moves to the tail end of the baking machine, the baking tray is removed from the bracket through the dumping mechanism, and the valve cover is dumped into the material bin of the hoist. A baking tray return conveyor belt is also provided at the baking station 4. The dumping mechanism places the dumped baking tray on the baking tray return conveyor belt. The baking tray is returned and transported to the tail end and set at the starting end of the baking machine to wait for the next batch of tray loading and baking processing.

[0035] When the number of valve covers in the silo reaches a preset value, the elevator drives the valve covers in the silo to be lifted and transports the valve covers to the grinding station 52. The grinding station 52 is provided with a grinding disc.

In this embodiment, the elevator is a vibrating discharge disc, which can lift and adjust the valve cover.

[0036] The cleaning station 6 is arranged at the end of the grinding station 52. The handling robot cooperates with the conveyor belt 8 to transport the valve cover to the cleaning station 6 for cleaning, and transports the cleaned valve cover to the packing station 7. The packing station 7 is provided with a palletizing robot, which palletizes and packs the cleaned valve cover.

[0037] Reference Figure 1 and Figure 2 , a positioning workpiece 9 is arranged on the conveyor belt 8, and the conveyor belt 8 positions and transports the valve cover through the positioning workpiece 9, so that the handling manipulator can accurately grab the valve cover. The positioning workpiece 9 includes a loading plate 91 and a plurality of positioning rods 92. In this embodiment, four positioning rods 92 are provided. The loading plate 91 is arranged above the rotating belt and is detachably connected to the conveyor belt by screws. The conveyor belt 8 mentioned here is preferably a chain plate conveyor belt. When the rotating belt is working, it drives the loading plate 91 to move synchronously.

[0038] Reference Figure 2 and Figure 3 The four positioning rods 92 are divided into two rows, and the two rows of positioning rods 92 are respectively located on both sides of the loading plate 91 along the width direction. All positioning rods 92 are arranged vertically and parallel to each other. Push rods 93 are arranged on both sides of the loading plate 91 along the width direction. Two positioning rods 92 in the same row correspond to a group of push rods 93. The push rods 93 pass through the loading plate along the width direction of the loading plate and are slidably connected with the loading plate.

[0039] Reference Figure 2 and Figure 3A connecting plate 94 is vertically fixed to one end of the push rod 93 close to the positioning rod 92. The connecting plate 94 is arranged along the length direction of the carrier plate. The positioning rod 92 passes through the connecting plate 94 and is slidably connected to the connecting plate 94 along the length direction of the connecting plate 94. When the push rod 93 moves along its own length direction, the connecting plate 94 drives the positioning rod 92 to move along the width direction of the carrier plate. Both ends of the carrier plate along the length direction are slidably connected to a moving plate 95. The moving plate 95 is arranged parallel to the push rod 93. The two positioning rods 92 at the ends of the length direction of the carrier plate are set as a group. The two positioning rods 92 in the same group correspond to one moving plate 95. The positioning rod 92 passes through the corresponding moving plate 95 and is slidably connected to the moving plate 95 along the length direction of the moving plate 95.

[0040] Reference Figure 2 and Figure 3 When the connection plate 94 drives the positioning rod 92 to move along the width direction of the carrier plate, the positioning rod 92 is pushed to move along the length direction of the moving plate 95, and the moving plate 95 cooperates with the connection plate 94 to position the positioning rod 92. The carrier plate is slidably connected with a push rod 96 along the width direction, and the push rod 96 is hinged with a linkage rod 951 in the transverse direction, and the end of the linkage rod 951 away from the push rod 96 is hinged with the connection plate 94. When the push rod 96 approaches the carrier plate, the linkage rod 951 drives the moving plate 95 to approach the middle position of the carrier plate.

[0041] Both the push rod 96 and the push rod 93 are connected with a straight rod 97 in a sliding manner along the axis direction. Taking the push rod 96 as an example, the push rod 96 is hollow, and the straight rod 97 is located inside the push rod 96 and is connected with the push rod 96 in a sliding manner along the axis direction. An elastic member 971 is provided between the push rod 96 and the straight rod 97. The elastic member 971 is a spring, one end of the spring is fixedly connected to the straight rod 97, and the other end is fixedly connected to the straight rod 97. In the natural state of the elastic member 971, the end of the straight rod 97 away from the carrier plate passes through the push rod 96 and extends in a direction away from the carrier plate.

[0042] Reference Figure 2 and Figure 3 , positioning blocks 98 are provided on both sides of the push rod 96 in the horizontal direction, and the positioning blocks 98 are slidably connected to the push rod 96 in the direction of approaching or moving away from the straight rod 97. The straight rod 97 is hinged with a swing rod 982 corresponding to the positioning block 98 in the horizontal direction, and one end of the swing rod 982 away from the straight rod 97 is hinged with the positioning block 98 in the horizontal direction. When the elastic member 971 is in the natural state, the positioning block 98 is in a position away from the straight rod 97. A plurality of positioning grooves 981 are evenly opened along the length direction on the side of the positioning block 98 away from the straight rod 97, and the carrier plate is fixedly connected with positioning teeth 911 corresponding to the positioning grooves 981. Under the action of the elastic member 971, the positioning block 98 approaches the positioning teeth 911, so that the positioning teeth 911 enter the positioning groove 981 and fit with the inner wall of the positioning groove 981.

[0043] Reference Figure 2 and Figure 3 The positioning teeth 911 cooperate with the positioning block 98 to limit the displacement of the push rod 96 along its own length direction, thereby limiting the positioning rod 92 along the width direction of the carrier plate. Similarly, the push rod 93 is provided with the same positioning structure as mentioned above, thereby limiting the displacement of the positioning rod 92 along the length direction of the carrier plate.

[0044] The valve cover is provided with a groove for mounting the working parts of the gas meter. In the initial state, the position of the positioning rod 92 on the carrier plate is adapted to the shape of the groove. When the valve cover is placed on the conveyor belt 8, the positioning rod 92 is inserted into the groove and fits with the inner wall of the groove. The carrier plate limits the valve cover by the positioning rod 92 to improve the transportation stability of the valve cover.

[0045] Reference Figure 2 and Figure 4 The conveyor belt 8 is provided with an adjusting member 10 for adjusting the position of the positioning rod 92. The adjusting member includes a mounting seat 140, a guide plate 110, a guide plate 120 and two groups of push plates 130. The mounting seat 140 is installed on one side of the conveyor belt 8 along the width direction.

The guide plate 110 includes two groups of straight plates 111, two groups of straight plates 112 and two groups of rotating plates 113. The two groups of straight plates 111 are parallel to each other and fixedly connected.

[0046] Reference Figure 2 and Figure 4 The mounting seat 140 is provided with a driving member 150, which includes a driving block 151 and a screw 152. The driving block 151 is slidably connected to the mounting seat 140 along the width direction of the conveyor belt 8, the straight plate 111 is fixedly connected to the driving block 151, and the screw 152 is located on the side of the mounting seat 140 away from the straight plate 111, and the screw 152 is rotatably connected to the mounting seat 140. The end of the screw 152 away from the mounting seat 140 passes through the driving block 151 and is threadedly connected to the driving block 151. When the screw 152 is rotated, the screw 152 pushes the driving block 151 to move along the width direction of the conveyor belt 8, thereby adjusting the position between the two straight plates 111.

[0047] Reference Figure 2 and Figure 4 The rotating plate 113 is connected to one end of the straight plate 111 in a lateral rotational manner. When the conveyor belt 8 is working, the valve cover is driven to move in the direction of the rotating plate 113 pointing to the straight plate 111. The straight plate 112 is located at one end of the rotating plate 113 away from the straight plate 111, and the straight plate 112 is hinged to the rotating plate 113 in a lateral manner. The two straight plates 112 are parallel to each other and fixedly connected. When the straight plate 112 moves, the rotating plate 113 is driven to move.

[0048] Reference Figure 2 and Figure 4 The mounting seat 140 is provided with a second driving member 160, which has the same structure as the first driving member 150. The second driving member 160 includes a second driving block 161 and a second screw 162. The second driving block 161 is slidably connected to the mounting seat 140 along the width direction of the conveyor belt 8, and the second screw 162 is rotatably connected to the mounting seat 140, and the second screw 162 passes through the second driving block 161 and is threadedly connected to the second driving block 161. When the second screw 162 is rotated, the second screw 162 drives the driving block to move along the width direction of the conveyor belt 8. The second straight plate 112 is slidably connected to the second driving block 161 along the length direction. When the second driving block 161 moves, it drives the second straight plate 112 to move, and then the second straight plate 112 drives the rotating plate 113 to rotate.

[0049] Reference Figure 3 and Figure 4 The structure of the guide plate 2 120 is consistent with that of the guide plate 1 110, and the guide plate 2 120 and the guide plate 1 110 are arranged vertically. When the carrier plate moves, the push rod 96 and the push rod 93 are driven to pass between the guide plate 1 110 and the guide plate 2 120. The push rod 96 and the push rod 93 are vertically fixedly connected to the driving column 931 at one end away from the carrier plate. The guide plate 1 110 corresponds to the push rod 93, and the driving column 931 of the push rod 93 is located on the side close to the guide plate 1 110. The two straight plates 2 112 of the guide plate 1 110, the two rotating plates 113, and the spacing between the two straight plates 1 111 constitute a guide groove.

[0050] Reference Figure 3 and Figure 4 When the position of the positioning rod 92 needs to be adjusted, the position of the guide plate 110 is adjusted by the driving member 150 and the driving member 2 160, so that the gap between the two straight plates 112 in the guide plate 110 is directly opposite to the driving column 931 of the push rod 93. When the bearing plate moves under the drive of the conveyor belt 8, the driving column 931 of the push rod 93 first enters the gap between the two straight plates 112. The push plate 130 is slidably connected with the mounting seat 140 in the horizontal direction, and the push plate 130 is located on the side of the guide plate 110 close to the mounting seat 140. The push plate 130 is provided with three sections, and the three sections of the push plate 130 are respectively distributed along the length direction of the straight plate 112, the rotating plate 113 and the straight plate 112. When the driving rod on the push rod 93 enters between the two straight plates, the straight rod 97 first contacts the push plate 130, and gradually approaches the bearing plate under the guiding action of the push plate 130, and the limit of the push rod 93 is released at this time.

[0051] Reference Figure 3 and Figure 4When the driving column 931 enters between the two rotating plates 113, under the guidance of the rotating plates 113, the driving column 931 drives the push rod 93 to approach or move away from the carrier plate, and then adjusts the position of the positioning rod 92 along the width direction of the carrier plate through the connecting plate 94. When the driving column 931 enters the gap between the two straight plates 111, the adjustment of the positioning column is completed. At this time, the straight rod 97 is separated from the push plate 130, and then the positioning column is positioned. Further, the position of the positioning column along the length direction of the carrier plate is adjusted by the guide plate 2 120 and the other push plate 130. In the process of adjusting the position of the positioning column, the operator only needs to adjust the guide plate 1 110 and the guide plate, which is conducive to improving the convenience of adjusting the position of the positioning rod 92.

[0052] The implementation principle of the automated processing production line of a gas meter valve cover in the embodiment of the present application is as follows: the valve cover is transferred between the injection molding station 1, the water outlet station 2, the deburring station 3, the baking station 4, the pre-grinding material station 51, the grinding station 52, the cleaning station 6 and the packing station 7 through the conveyor belt 8 and the handling manipulator, so as to realize the automatic water outlet, automatic deburring, automatic baking, automatic grinding, automatic cleaning and automatic packing of the valve cover, which is conducive to realizing the production automation of the valve cover. At the same time, the valve cover is positioned by positioning the workpiece 9 during transportation, which is conducive to improving the transportation stability of the valve cover. By setting the guide plate 1 110, the guide plate 2 120 and the two groups of push plates 130, it is convenient to adjust the position of the positioning rod 92 along the width and length direction of the carrier plate, and during the adjustment process, there is no need for the operator to adjust the positioning workpiece 9 one by one, which is conducive to improving the convenience of adjusting the position of the positioning rod 92, thereby improving the production convenience of the valve cover and improving the production efficiency of the valve cover production line.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
