Description

Technical Field

They are widely used in daily life. Energy-saving water heaters are mainly composed of heat exchangers, water tanks, control systems and other components. After the energy-saving water heaters are manufactured, they are generally placed on a square packaging box base for unified transportation, and appearance quality inspection and labeling operations are carried out during the transportation process.

[0031] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following will describe the specific embodiments of the present invention in detail with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0032] Please refer to Figure 1 , an automated conveying device for manufacturing an energy-saving water heater, including automatic conveying platforms 1 arranged uniformly front and back. The automatic conveying platform 1 is composed of a belt conveyor 11 and front and rear fixing frames. The belt conveyor 11 is driven by an existing drive source (the drive source is not shown in the figure and only a part of the belt conveyor 11 is shown in the figure). Installation through slots are provided on the belt conveyor 11. Shifting units 12 are provided at the upper ends of the belt conveyor 11. A calibration unit 13 is commonly provided between the upper right sides of the front and rear automatic conveying platforms 1.

[0033] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , the shifting unit 12 includes support plates 183 installed uniformly left and right between the front and rear slot walls of the installation through slots. A placement plate 121 for placing the water heater 2 is provided at the upper end of the support plate 183. A rotating column passing through the support plate 183 is installed in the middle of the lower end of the placement plate 121. An arc-shaped through slot 122 is provided on the placement plate 121. A clamping plate 123 is installed at the lower end of the rotating column. A rotating shaft 124 is provided below the belt conveyor 11. A clamping slot for clamping and cooperating with the clamping plate 123 is provided at the upper end of the rotating shaft 124. A U-shaped plate 125 is installed on the outer ring surface at the right end of the rotating shaft 124. A limiting plate 126 is rotatably installed between the front and rear vertical sections of the U-shaped plate 125 through a torsion spring shaft. A driving assembly for driving the rotation of the rotating shaft 124 is provided at the lower end of the rotating shaft 124. Side baffles 131 located at the upper end of the placement plate 121 are provided on the sides of the front and rear fixing frames of the same automatic conveying platform 1 that are close to each other. Spring telescopic rods 132 arranged uniformly left and right are connected between the side baffles 131 and the fixing frames. The left end of the side baffle 131 is inclined away from the placement plate 121.

[0034] Before conveying, the water heater 2 has been manufactured and its bottom is fixed in position through the packaging box base, and the relative position between the water heater 2 and the packaging box base is accurately consistent. Symmetric mounting brackets are provided on the outside of the water heater 2 up and down. Symmetric mounting holes are provided on the mounting brackets. The mounting brackets can be used in cooperation with other mounting parts through the mounting holes to install the water heater 2 in the required usage scenario.

[0035] During the specific operation: first, it is necessary to use the existing device to simultaneously place multiple rows of water heaters 2 and packaging box bases from the upper left side of the front-to-back arranged automatic conveying table 1 on the upper end of the corresponding placement plate 121, and then the belt conveyor 11 can be driven from left to right by the existing driving source, and the placement plate 121 drives the packaging box base and the water heater 2 to move to the right synchronously. During this process, the front-to-back arranged automatic conveying tables 1 work simultaneously (only part of the automatic conveying tables 1 is shown in the figure), so that the water heaters 2 on different placement plates 121 can move to the right synchronously, and at the same time, the water heaters 2 can be continuously placed on the upper end of the left placement plate 121 for transportation through the existing device.

[0036] Since it is difficult to ensure that the packaging box base and the water heater 2 are centered on the upper end of the placement plate 121, the packaging box base and the water heater 2 as a whole will be slightly offset relative to the placement plate 121. In the process of the placement plate 121 driving the water heater 2 to move to the right, the packaging box base at the lower end of the water heater 2 gradually collides with the inclined section at the left end of the side baffle 131, and the side baffle 131 is squeezed to compress the spring telescopic rod 132 and move back and forth along the upper end of the placement plate 121. The front and rear side baffles 131 can limit the packaging box base in the front and rear directions, and the spring telescopic rod 132 can be used to adjust the placement direction of the packaging box base, thereby realizing adaptive position correction of the packaging box base and the water heater 2 as a whole.

[0037] See also Figure 2 and Figure 5 The driving assembly includes a transmission pulley 133 installed at the lower end of the rotating shaft 124. The transmission pulleys 133 at the lower ends of different rotating shafts 124 are connected by transmission belts. A C-shaped frame 135 with a horizontal section rotatably connected to the transmission pulley 133 is installed between the lower ends of the frontmost and rearmost fixed frames. A driving motor 136 is installed at the lower end of the horizontal section of the C-shaped frame 135. The output shaft of the driving motor 136 rotates through the horizontal section of the C-shaped frame 135 and is connected to the transmission pulley 133 located in the middle.

[0038] See also Figure 3 , Figure 4 and Figure 5 An extension plate 137 is installed at the front end of the rear fixed frame of the same automatic conveying platform 1, and an alignment column 138 is set at the lower end of the extension plate 137. The alignment column 138 is rotatably installed at the lower end of the connecting plate 139. The connecting plate 139 is connected to the extension plate 137 for forward and backward sliding through an adjusting spring. An alignment plate 140 is installed at the rear end of the placement plate 121, and an alignment groove matching the alignment column 138 is opened at the rear end of the alignment plate 140.

[0039] When the placing plate 121 drives the packaging box base and the water heater 2 to move right, the card plate 123 moves right synchronously with the placing plate 121 through the rotating column and gradually engages with the card slot on the rotating shaft 124. When the card plate 123 moves to fully engage with the card slot, the right end of the card plate 123 conflicts with the limit plate 126 located at the right end of the rotating shaft 124, and the belt conveyor 11 stops conveying the placing plate 121 and the water heater 2. At this time, the water heater 2 just reaches the work station where the appearance quality inspection can be performed. Then, the driving motor 136 can be used to drive the transmission pulley 133 in the middle to rotate, and the middle transmission pulley 133 drives the other transmission pulleys 133 to rotate synchronously through the transmission belt. Under the cooperation of the card plate 123 and the card slot, the transmission pulley 133 drives the card plate 123 and the rotating column to rotate synchronously through the rotating shaft 124, and the rotating column drives the placing plate 121 to rotate synchronously around the supporting plate 183, and the placing plate 121 drives the packaging box base and the water heater 2 to rotate synchronously. The packaging box base will press against the side baffle 131 to move it back and forth, but the resistance applied to the packaging box base by the side baffle 131 will not cause the packaging box base to deform. Of course, the length of the side baffle 131 can also be selected according to actual conditions, so that before the packaging box base and the water heater 2 rotate with the placement plate 121, the packaging box base has moved out of the area between the front and rear side baffles 131. With the cooperation of the transmission pulley 133 and the conveyor belt, the water heater 2 in the front and rear directions keeps rotating synchronously. During this process, the appearance quality of the outside of the water heater 2 can be manually inspected, but the rotation speed of the transmission pulley 133 needs to be slow and uniform to ensure that the placement plate 121 can drive the packaging box base and the water heater 2 to rotate slowly and evenly, thereby ensuring that the manual inspection can better observe whether there are defects or other quality problems on the outside of the water heater 2. If the water heater 2 has appearance quality problems, it can be removed. If not, it can continue to be transported to the right for labeling.

[0040] During the appearance quality inspection of the water heater 2, the placement plate 121 can drive the alignment plate 140 to rotate synchronously. In the initial state, the alignment post 138 is located in the alignment groove at the rear end of the alignment plate 140. As the placement plate 121 rotates, the alignment post 138 is squeezed by the alignment plate 140 and rotates, and moves along the extension plate 137 away from the placement plate 121 through the cooperation of the connecting plate 139 and the adjusting spring. When the placement plate 121 rotates one circle, the alignment plate 140 contacts the alignment post 138 again. Under the action of the connecting plate 139 and the adjusting spring, the alignment post 138 cooperates with the alignment groove again. At this time, the water heater 2 has just completed the appearance quality inspection. The cooperation between the alignment column 138 and the alignment plate 140 can be used to limit the circumferential rotation of the placement plate 121 and the clamping plate 123, thereby ensuring that the subsequent clamping plate 123 can be smoothly moved to the right to move away from the clamping slot of the rotating shaft 124, ensuring that the placement plate 121 can drive the packaging box base and the water heater 2 to move smoothly and stably to the labeling position. In addition, in the process of the belt conveyor 11 driving the placement plate 121 to move right to the appearance quality inspection station, the right shift position of the placement plate 121 can also be positioned through the cooperation between the alignment column 138 and the alignment plate 140.

[0041] After the water heater 2 rotates one circle to complete the appearance quality inspection, the driving motor 136 stops working. At this time, the slot on the rotating shaft 124 and the card plate 123 still maintain the card connection direction in the initial state. Then the belt conveyor 11 can continue to drive the placement plate 121 and the water heater 2 to continue to move right. The card plate 123 then smoothly leaves the slot on the rotating shaft 124. While the card plate 123 moves right, it pushes the limit plate 126 to the right. The limit plate 126 rotates to the right around the shaped plate 125 under the action of the torsion spring shaft. When the card plate 123 is away from the rotating shaft, After 124, the limit plate 126 turns left and resets under the action of the torsion spring shaft, so that it can limit the subsequent card plate 123. By limiting the movement of the card plate 123 by the limit plate 126, it can be ensured that the card slot and the card plate 123 can be firmly engaged with each other, and it can be avoided that the card plate 123 and the card slot are not in the right position, which causes the card plate 123 to be unable to rotate synchronously and stably with the rotating shaft 124, thereby ensuring that the placement plate 121 can drive the packaging box base and the water heater 2 to rotate stably and effectively as a whole, thereby improving the efficiency of appearance quality inspection.

[0042] See also Figure 1 , Figure 2 , Figure 3 and Figure 6The right lower end of the belt conveyor 11 is provided with a positioning assembly, which includes an arc plate 141 connected to the arc groove 122 for sliding up and down. A sliding groove for the arc plate 141 to slide up and down is opened on the support plate 183. An arc base 142 located below the belt conveyor 11 is installed at the lower end of the arc plate 141. An L-shaped plate 143 is installed at the right end of the arc base 142. The height of the vertical section of the L-shaped plate 143 is higher than the arc plate 141. A connecting frame 144 is installed at the lower end of the front and rear arc bases 142. Vertical guide rails 145 are installed at the lower ends of the front and rear fixed frames. The connecting frame 144 is installed between the front and rear vertical guide rails 145 for sliding up and down. The vertical guide rails 145 are installed between the front and rear vertical guide rails 145. An electric slider fixedly connected to the connecting frame 144 is slidably installed on the upper surface of the arc plate 141, a right-angle groove 146 is provided at the upper end of the arc plate 141, a positioning block 147 is provided at the upper end of the right-angle groove 146, an annular groove 148 is provided on the outer ring surface of the arc plate 141, the positioning block 147 is slidably connected to the right-angle groove 146, a bolt slidably connected to the annular groove 148 is installed at one end of the positioning block 147 close to the L-shaped plate 143, a nut is threadedly installed after the bolt passes through the annular groove 148, the positioning assembly also includes a cross reference plate 149, a front-to-back symmetrical plug rod is installed on the left side of the cross reference plate 149, a moving rod 151 is installed in the middle of the right end of the cross reference plate 149, and a ball is rollingly installed on the right end of the moving rod 151.

[0043] Before the water heater 2 that has passed the appearance quality inspection continues to move to the right, the insertion rods on the front and rear sides of the cross reference plate 149 can be quickly inserted into the mounting holes on the mounting frame below the water heater 2 by hand, and the cross reference plate 149 can be quickly clamped on the mounting frame. At this time, the moving rod 151 is just located in the middle of the mounting frame, and with the cooperation of the insertion rod and the mounting hole, the cross reference plate 149 is limited in the front and rear directions to ensure that the cross reference plate 149 and the moving rod 151 can be stably and accurately fixed on the mounting frame. The placement plate 121 that continues to move to the right drives the packaging box base and the water heater 2 as a whole to gradually reach the labeling station. Before this, the connecting frame 144 can be driven by the electric slider to move upward along the front and rear vertical guide rails 145, and the connecting frame 144 drives the front and rear arranged arc base 142 to move upward synchronously, and the L-shaped plate 143 moves upward synchronously with the arc base 142 until the L-shaped plate The vertical section of 143 extends out of the belt conveyor 11 and is higher than the placement plate 121. Since the height of the vertical section of the L-shaped plate 143 is higher than the curved plate 141, the curved plate 141 is still located below the belt conveyor 11 and will not interfere with the movement of the placement plate 121. When the placement plate 121 moves right to the vertical section of the L-shaped plate 143 and conflicts with it, the belt conveyor 11 stops conveying, and the placement plate 121 drives the packaging box base and the water heater 2 as a whole to be located at the labeling station. Then the connecting frame 144 can continue to move upward, and the curved base 142 drives the L-shaped plate 143 and the curved plate 141 to move upward synchronously. The curved plate 141 can pass through the sliding groove and the curved groove 122 on the support plate 183 and move upward to the curved base 142 and conflict with the lower end of the placement plate 121. At this time, the moving rod 151 at the right end of the cross reference plate 149 just conflicts with the groove wall of the right-angle groove 146.

A matching rod is provided which is slidably connected to the threaded groove of the threaded rod 156.

[0046] See also Figure 1 , Figure 7 and Figure 8The linkage member includes a rotating circular plate 176 installed at the upper end of the horizontal plate 173, a driven pulley 177 is installed at the upper end of the rotating circular plate 176, and the driven pulley 177 is connected to the driving pulley 155 through a connecting belt transmission.

[0047] The water heater 2 that arrives at the labeling station is just located under the corresponding clamping assembly. At this time, the water heater 2 located at the appearance quality inspection station can be rotated and appearance quality inspected in the same way. Although the position of the packaging box base and the water heater 2 as a whole has been pre-corrected to center the packaging box base and the water heater 2, the position of the packaging box base and the water heater 2 at the upper ends of the front and rear different placement plates 121 is still not completely consistent, and there is a certain tilt angle. At this time, it is necessary to fine-tune the angle between the water heater 2 and the packaging box base again. In this process, the inverted U-shaped frame 153 can be first controlled by the existing control source to move downward along the front and rear mounting plates 152 until the inverted U-shaped frame 153 drives the clamping assembly to move to a suitable clamping position, and then the push plate 181 can be pushed by the hydraulic cylinder 182 to move upward along the front and rear vertical sections of the inverted U-shaped frame 153, and the push rods 179 arranged front and back are all As the push plate 181 moves upward, the push rod 179 drives the moving block 175 to move upward, and the moving block 175 drives the L-shaped connecting rods 174 on the left and right sides to rotate synchronously around the hinge point between it and the cross plate 173 through the second pin shaft. At the same time, the other ends of the L-shaped connecting rods 174 on the left and right sides drive the left and right rectangular rods 172 to move synchronously in the opposite direction along the cross plate 173 through the first pin shaft until the left and right clamping plates 171 on the left and right sides synchronously press against the water heater 2, thus completing the clamping and fixing of the water heater 2. The clamping plate 171 contacts the water heater 2 through the elastic sponge, effectively preventing excessive clamping force from scratching the surface of the water heater 2. In addition, the water heater 2 is fixed to the upper end of the placement plate 121 through the clamping assembly, ensuring that the water heater 2 is labeled in a stable state and that the water heater 2 will not move or shake during the labeling process, thereby improving the labeling accuracy and labeling efficiency.

[0048] Next, the cylinder 161 can be used to pull the pull plate 158 to move downward along the pull rod 157, and the pull plate 158 drives the square blocks arranged in the front and rear to move downward synchronously through the control spring 159, and the threaded rod 156 moves downward synchronously with the square blocks, and the active pulley 155 rotates around the threaded rod 156 as the threaded rod 156 moves downward. At the same time, the active pulley 155 drives the driven pulley 177 to rotate synchronously around the push rod 179 through the connecting belt, and the driven pulley 177 drives the rotating circular plate 176 to rotate synchronously, and the rotating circular plate 176 drives the cross plate 173 and the clamping assembly as a whole. Rotate, the clamping assembly clamps the water heater 2 and rotates synchronously with the packaging box base, and the cross reference plate 149 and the moving rod 151 on the mounting frame below the water heater 2 rotate synchronously accordingly, and the moving rod 151 rotates smoothly along the right-angle groove 146 through the ball bearing until the moving rod 151 conflicts with the positioning block 147. At this time, the mounting frame of the water heater 2 is located on the right side, and the water heater 2 clamped by the clamping assembly and the packaging box base as a whole are just parallel to the front and back sides of the placement plate 121. The labeling position of the water heater 2 is located on the front side, and the labeling operation of the water heater 2 can be carried out at this time.

[0049] Since the positions of the front and rear water heaters 2 are slightly deviated during clamping, the angles at which the water heaters 2 are clamped and rotated to the labeling position by different clamping assemblies are different. In the process of the pull plate 158 driving the square plate and the threaded rod 156 to move downward through the control spring 159, the more the threaded rod 156 moves downward, the more the active pulley 155 and the driven pulley 177 rotate. Correspondingly, the larger the angle at which the water heater 2 is clamped and rotated by the clamping assembly, no matter in which direction the packaging box base and the water heater 2 are tilted, the direction of the packaging box base and the water heater 2 can be unified by moving the threaded rod 156 downward, and the rotation adjustment directions of the positions of different packaging box bases and water heaters 2 are always consistent. After the position adjustment of one water heater 2 is completed, the positions of the remaining water heaters 2 may need to be adjusted. At this time, the pull plate 158 can be continued to be pulled downward by the cylinder 161. When the moving rod 151 and the positioning Under the action of block 147, the adjusted water heater 2 and the clamping assembly no longer rotate, and the corresponding driven pulley 177 and the active pulley 155 also remain stationary. As the pull plate 158 continues to be pressed downward, the threaded rod 156 that has not moved down to the appropriate position continues to move downward with it through the square block and the control spring 159. The threaded rod 156 and the square plate that have moved down to the appropriate position no longer move. At this time, the pull plate 158 can move smoothly downward along the pull rod 157 by compressing the control spring 159 until all the clamping assemblies and the water heater 2 are rotated to the appropriate labeling position. At this time, multiple water heaters 2 arranged in front and behind can be accurately labeled at the same time. The correction unit 13 is used to unify the orientation of the water heater 2, and there is no need to manually locate and label the water heaters 2 in different orientations. This not only saves time and effort, but also helps to improve the accuracy of labeling, thereby improving the efficiency of conveying and labeling.

[0050] When the labeling position of the water heater 2 changes, in order to ensure that the labeling positions of different water heaters 2 are unified and always facing forward, the positioning block 147 can be moved along the annular groove 148 to change the interference position between the moving rod 151 and the positioning block 147, thereby changing the unified orientation of the water heater 2 mounting frame. With reference to the positioning blocks 147 and the moving rod 151 at different positions, the packaging box base and the water heater 2 can be rotated and adjusted to a suitable labeling position. After the positioning block 147 is moved to a suitable position, the positioning block 147 can be fixed in the right-angle groove 146 by the cooperation between the bolt and the nut.

[0051] After completing the labeling operation of the water heater 2, the clamping assembly can release the clamping fixation of the water heater 2 in the opposite manner as described above, and move it upward away from the water heater 2. At the same time, the clamping assembly can be rotated in the opposite direction to reset it, and the arc plate 141 and the L-shaped plate 143 can be synchronously moved downward and reset to be away from the placement plate 121. Then, the labeled water heater 2 can continue to be conveyed to the right by the belt conveyor 11. Subsequently, the cross reference plate 149 on the water heater 2 mounting frame can be removed, and the labeled water heaters 2 can be uniformly removed and packaged. As the water heater 2 moves to the right after labeling, the water heater 2 after the appearance quality inspection moves to the right synchronously and completes the labeling in the same way. Similarly, the appearance quality inspection and labeling operations can be performed on multiple rows of water heaters 2 in the continuous transportation process.
