Technical Field

[0001] The present application relates to the technical field of automatic refueling, and in particular to a refueling mechanism, a refueling device and a production line. Background Art

[0002] During the production process, when there is a need to refuel the product, if the refueling is done manually, it will lead to high labor intensity for operators and low production efficiency.

[0003] When an automated refueling mechanism is used, the refueling gun is usually driven by an oil cylinder or an air cylinder to move the refueling gun relative to the refueling port of the product to be refueled, thereby docking or separating with the refueling port of the product to be refueled. When the refueling gun docks with the refueling port on the product to be refueled at a certain speed, the refueling gun still has inertia after docking, which may cause the refueling gun to impact the refueling port of the product to be refueled. In serious cases, the refueling gun or the product to be refueled may be damaged. Utility Model Content

[0053] The buffer component 2 is arranged opposite to the refueling gun 110. When the refueling gun 110 is docked with the refueling port, the refueling gun 110 also contacts the buffer component 2. The buffer component 2 is used to apply a buffer force to the refueling gun 110 away from the product to be refueled 18, and is used to alleviate the movement inertia of the refueling gun 110 moving toward the refueling port, so as to avoid high-speed impact on the refueling port and the product to be refueled 18 due to the existence of movement inertia after the refueling gun 110 is docked with the product to be refueled 18, causing damage to the product to be refueled 18 or the refueling gun 110.

[0054] It should be noted that the refueling mechanism of the present application can be applied to the automatic refueling of any product.

After the refueling gun 110 is docked with the refueling port, the abutting end 211 contacts the refueling gun 110, and a buffer force is applied to the refueling gun 110 through the abutting end 211, which can reduce the movement inertia of the refueling gun 110 after the docking is completed, and reduce the impact of the refueling gun 110 on the refueling product 18.

In order to avoid scratches or depressions on the surface of the product to be refueled 18 due to rigid contact between the clamping member 1011 and the surface of the product to be refueled 18 during the clamping process, the clamping member 1011 is preferably made of elastic material. Specifically, the clamping member 1011 can be a rubber sleeve or other component.

[0081] As a specific embodiment of the present application, the clamping assembly 10 includes two symmetrically arranged clamping rods 1010, which can be used to apply uniform clamping force to both sides of the product to be refueled 18 to prevent the product to be refueled 18 from being deflected due to uneven force. The clamping assembly 10 also includes a fourth connecting plate 1020, and the two clamping rods 1010 are fixedly arranged on the fourth connecting plate 1020 and connected into a whole, so that the two clamping rods 1010 can move synchronously.

[0082] In some embodiments of the present application, the clamping assembly 10 further includes a third driving member 1030, which is connected to the fourth connecting plate 1020 and can drive the fourth connecting plate 1020 and the clamping rod 1010 to reciprocate along the third direction. Specifically, the third driving member 1030 can be a linear actuator such as an oil cylinder or a pneumatic cylinder.

[0083] In some embodiments of this application, please refer to Figure 8 The clamping mechanism also includes a third detection component 11, which is arranged corresponding to the clamping component 10 and is used to detect the movement of the clamping component 10, thereby sending a displacement signal of the clamping component 10 to the control module, so as to facilitate the start and stop control and speed control of the third driving member 1030 through the control module.

[0084] In some embodiments of this application, please refer to Figure 8 and Fig. 9 The clamping mechanism also includes a third mounting seat 12, and the clamping assembly 10 and the third detection assembly 11 are both arranged on the third mounting seat 12, so that the clamping mechanism can be connected into a whole, which is convenient for realizing the overall layout of the clamping mechanism through the third mounting seat 12.

[0085] In order to enable the pressing assembly 10 to move smoothly along the third direction, in some embodiments of the present application, please refer to Figure 8 The third mounting seat 12 is also provided with a third guide assembly 13, which is connected to the clamping assembly 10 so that the clamping assembly 10 slides along the third direction. Specifically, the third guide assembly 13 can be a slide rail, a slider structure, or a guide rod, a guide cylinder structure, all of which can achieve the purpose of the present application.

[0086] As a specific embodiment of this application, please refer to Figure 8 and Fig. 9The third mounting seat 12 includes a fifth connecting plate 1210, the third driving member 1030 is fixedly arranged on the fifth connecting plate 1210, and the piston rod of the third driving member 1030 is connected to the fourth connecting plate 1020. The third guide assembly 13 includes two symmetrically arranged second guide rods 1310, and also includes a second linear bearing 1320 arranged one-to-one with the two second guide rods 1310, wherein one end of the second guide rod 1310 is connected to the fourth connecting plate 1020, and the other end of the second guide rod 1310 is inserted into the second linear bearing 1320, and the second guide rod 1310 and the second linear bearing 1320 can reciprocate and slide along the second direction, and the third direction is the axial direction of the second guide rod 1310. The second linear bearing 1320 is fixedly arranged on the fifth connecting plate 1210, and can provide a stable guiding effect for the second guide rod 1310. The fifth connecting plate 1210 has a fourth mounting hole 1211 extending therethrough, and the second guide rod 1310 can pass through the fourth mounting hole 1211 to slide relative to the fifth connecting plate 1210, so as to prevent the plate body of the fifth connecting plate 1210 from interfering with the sliding of the second guide rod 1310. The fifth connecting plate 1210 also has a fifth mounting hole 1212 extending therethrough, and the piston rod of the third driving member 1030 can pass through the fifth mounting hole 1212 to achieve connection with the fourth connecting plate 1020.

[0087] It should be noted that the third detection component 11 can use a single displacement sensor to detect the displacement of the clamping component 10, thereby obtaining the displacement signal of the clamping component 10, or a plurality of proximity switches can be arranged in sequence on the sliding path of the clamping component 10 or the second guide rod 1310 to realize the detection of the moving position of the clamping component 10. The third detection component 11 is arranged corresponding to the clamping component 10, and can directly detect the displacement of components in the clamping component 10, or detect the displacement of components that move synchronously with the clamping component 10, such as the displacement of the second guide rod 1310, both of which can achieve the purpose of the present application.

[0088] As a specific embodiment of this application, please refer to Figure 8The third detection assembly 11 includes at least two third sensors 1110, which are proximity switches and can detect the starting position and the end position of the pressing assembly 10 during the sliding process. Specifically, the end of the second guide rod 1310 is provided with a second sensing member 1311, which is arranged relative to the third sensor 1110 and is used to cooperate with the third sensor 1110 to realize the position signal detection of the second guide rod 1310. Since the second guide rod 1310 moves as a whole with the pressing rod 1010 and other components, the position signal detection of the pressing rod 1010 and the pressing member 1011 can be indirectly realized to realize the motion control of the pressing member 1011. The third detection assembly 11 also includes a third bracket 1120, which is fixedly arranged on the third mounting seat 12, and the two third sensors 1110 are fixedly arranged on the third bracket 1120, so that the third sensor 1110 can be arranged along the sliding path of the second guide rod 1310.

[0089] In some embodiments of the present application, the third mounting seat 12 further includes a sixth connecting plate 1230 vertically connected to one side of the fifth connecting plate 1210. When the sixth connecting plate 1230 is used to connect with other components at the production site, the fifth connecting plate 1210 can be extended in a direction away from other components to form an extended bracket, so as to facilitate the alignment of the pressing assembly 10 with the middle area of ​​the product to be refueled 18. In order to ensure the structural strength of the third mounting seat 12, a reinforcing plate 1220 is further provided between the fifth connecting plate 1210 and the sixth connecting plate 1230. Figure 8 shown.

[0090] The embodiment of the present application provides a production line, including the refueling device in the above embodiment, and the production line also includes a conveying device 14 for conveying the product 18 to be refueled to the refueling device for automatic refueling. Fig.10 The conveying device 14 is provided with a tray 15 for carrying the product 18 to be refueled, and the tray 15 is provided with a positioning part matched with the positioning assembly 6. The positioning column 611 of the positioning assembly 6 can be inserted into the positioning part of the tray 15 to align the position of the tray 15, so that the refueling port of the product 18 to be refueled and the quick connector 111 of the refueling mechanism can be accurately positioned.

[0091] It should be noted that the positioning mechanism can be disposed above the tray 15 or below the tray 15, and both can achieve the purpose of the present application. However, when the positioning mechanism is disposed above the tray 15, a certain space needs to be reserved on the edge of the tray 15 to set the positioning portion, which causes the structural size of the tray 15 to become larger, and when the positioning mechanism is disposed above the tray 15, there is a risk of collision with the product 18 to be refueled. Therefore, it is preferred to dispose the positioning mechanism below the tray 15, and the positioning portion can be disposed at any position at the bottom of the tray 15. At this time, the conveying device 14 is preferably a roller conveying device 14, and there is a spacing between two adjacent rollers to facilitate the positioning rod 610 to move upward and insert into the positioning portion at the bottom of the tray 15, such as Fig.11 At this time, the second direction is the vertical direction.

[0092] The clamping mechanism can be arranged above the product 18 to be refueled or on both sides of the product 18 to be refueled, and both can achieve the purpose of the present application. However, when the clamping mechanism is arranged above the product, only one clamping mechanism is required to fix the product 18 to be refueled. Therefore, it is preferred to arrange the clamping mechanism above the product 18 to be refueled. In this case, the third direction is the vertical direction. The production line also includes a frame 17 with a certain height. The third mounting seat 12 of the clamping mechanism is connected to the frame 17, so that the clamping assembly 10 can be located above the product 18 to be refueled. Fig.10 and Fig.11 shown.

[0093] In some embodiments of this application, please refer to Fig.11 The bottom of the tray 15 has a through hole, and the refueling mechanism is arranged below the conveying device 14. The quick connector 111 can pass through the gap between the rollers, and then pass through the through hole to connect with the product to be refueled 18, and can be docked with the refueling port at the bottom of the product to be refueled 18 to achieve refueling. After refueling, the quick connector 111 is separated from the refueling port, and the residual oil inside the quick connector 111 can flow back to the bottom of the quick connector 111 or the oil pipe under the action of gravity, and will not drip on the electric drive and other products due to gravity. At this time, the first direction is the vertical direction.

[0094] In some embodiments of the present application, the production line further includes a base plate 16, and the frame 17, the first mounting seat 4 and the second mounting seat 8 are all arranged on the base plate 16, so that the refueling device can be arranged in the production line, such as Figure 5 and Fig.10 shown.

[0095] See also Figures 1 to 11 In some embodiments of the present application, the refueling method of the above production line is as follows:

[0096] Step 1: multiple products to be refueled 18 are arranged one by one on multiple trays 15, and the multiple trays 15 are arranged in sequence along the conveying direction of the conveying device 14;

[0097] Step 2: The conveying device 14 moves the tray 15 carrying the product 18 to be refueled to the refueling station. At this time, the tray 15 is located above the positioning mechanism, and the positioning column 611 extends upward and inserts into the positioning part at the bottom of the tray 15 to achieve accurate positioning of the tray 15. At this time, the conveying device 14 stops;

[0098] Step 3: The pressing rod 1010 extends downward and presses against the upper part of the product 18 to be refueled, so that the product 18 to be refueled in the tray 15 remains stationary;

[0099] Step 4: The refueling gun 110 extends upward, and the quick connector 111 is docked with the refueling port of the product 18 to be refueled. During docking, the abutting end 211 of the buffer assembly 2 contacts the upper surface of the connecting frame 113, reducing the inertia of the refueling gun 110 and the impact of the refueling gun 110 on the product 18 to be refueled. The refueling gun 110 refuels the product 18 to be refueled through the refueling port;

[0100] Step 5: After refueling is completed, the refueling gun 110 moves downward; then the pressing assembly 10 moves upward to release the product 18 to be refueled; finally, the positioning rod 610 moves downward to separate from the tray 15. The conveying device 14 starts to move the next product 18 to be refueled to the refueling station.

[0101] Step 6: According to steps 2 to 5, the next product 18 to be refueled is automatically refueled to achieve batch automatic refueling production.

[0102] The present application sets a quick connector 111 in the refueling mechanism, which allows the refueling gun 110 to move along a first direction to achieve a quick connection with the product to be refueled 18. Since the refueling gun 110 needs to dock with the refueling port at a certain speed, the buffer component 2 set in the refueling mechanism can buffer the movement inertia of the refueling gun 110 after the docking is completed, so as to avoid the refueling gun 110 from impacting the product to be refueled 18 after the docking is completed, thereby preventing the product to be refueled 18 from being damaged.

[0103] When the refueling mechanism of the present application is applied to the production of electric drive and other products, the degree of automation of product production can be improved, which is beneficial to improving the production efficiency of electric drive and other products.

[0104] The above embodiments are only preferred embodiments for fully illustrating the present application, and the protection scope of the present application is not limited thereto. Any equivalent substitution or change made by a person skilled in the art based on the present application is within the protection scope of the present application.
