Description

Technical Field

[0001] The present application relates to the technical field of mechanical assembly, and in particular to an extraction device. Background Art

[0002] In the assembly and production process of many types of products, it is often necessary to extract sheet-shaped workpieces. For example, before assembling the high-voltage relay of a handheld charging gun for a car, the semi-finished product used to assemble the high-voltage relay will be stuffed with a plug to prevent the installation position of a part in the semi-finished product from being too low. At the beginning of assembly, the plug needs to be pulled out so that other parts can be loaded into the semi-finished product in the subsequent process to finally form a finished product.

[0003] However, in the prior art, the method of extracting the sheet workpiece is usually to use a cylinder to push the sheet workpiece hard, so that the sheet workpiece is separated from the product and freely enters the receiving box. The above extraction method usually causes the sheet workpiece to be scattered in an unfixed position due to unstable air pressure and differences in the size of the sheet workpiece, resulting in failure to ensure that all the sheet workpieces can fall into the receiving box, making it difficult for the receiving box to neatly collect the ejected sheet workpieces.

If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0038] As described in the background technology, in the assembly and production process of many types of products, it is often necessary to extract sheet workpieces. However, in the prior art, the method of extracting sheet workpieces is usually to use a cylinder to hard-pull the sheet workpieces, so that the sheet workpieces are separated from the products and freely enter the receiving box. The above extraction method usually causes the sheet workpieces to be scattered in unfixed positions due to unstable air pressure and differences in the sizes of the sheet workpieces, resulting in the inability to ensure that all the sheet workpieces can fall into the receiving box, which makes it difficult for the receiving box to neatly collect the ejected sheet workpieces.

[0039] To this end, the present application provides a pulling device, which is used to smoothly pull out sheet workpieces from the product and enable the pulled sheet workpieces to fall neatly to a specified position, so as to overcome the problem of the prior art that the sheet workpieces cannot be neatly collected by using a cylinder to harden the sheet workpieces.

[0040] The structure of the extraction device in the present application is described below by taking the sheet workpiece extracted by the extraction device as a plug sheet used in assembling a high-voltage relay of a vehicle charging gun as an example. It can be understood that in other embodiments, the extraction device of the present application is not limited to extracting only plug sheets, but can also extract any type of sheet workpiece, which is not limited here.

[0041] See also Figure 1 , Figure 1 A schematic diagram of an extraction device 10 provided in an embodiment of the present application is shown. The extraction device 10 provided in an embodiment of the present application includes a machine platform 100, an extraction mechanism 200 and a clamping mechanism 300, wherein the extraction mechanism 200 and the clamping mechanism 300 are arranged on the machine platform 100, the extraction mechanism 200 is used to extract the sheet workpiece from the product, and the clamping mechanism 300 is used to clamp the product when the extraction mechanism 200 extracts the sheet workpiece from the product, so as to prevent the product from shaking randomly when the extraction mechanism 200 extracts the sheet workpiece.

[0042] In some embodiments, the extraction mechanism 200 includes a first driving member 210 and an extraction assembly 220 disposed on the machine 100. The extraction assembly 220 is connected to the first driving member 210 and is slidably connected to the machine 100. The first driving member 210 is used to drive the extraction assembly 220 to move along a first horizontal direction (the X direction shown in the figure) so as to extract the sheet workpiece from the product.

[0043] Specifically, see Figure 2 and Figure 3 The extraction assembly 220 includes a connection seat 221 and a second driving member 222, wherein the connection seat 221 is slidably disposed on the machine 100, and one end of the connection seat 221 along the second horizontal direction (i.e., the Y direction shown in the figure) is connected to the first driving member 210, and the other end is suspended relative to the machine 100 and is provided with a horizontally disposed lining plate 223, the lining plate 223 is used to carry the sheet workpiece, and the second driving member 222 is disposed on the connection seat 221 and is spaced apart from the lining plate 223 in the vertical direction, wherein the second horizontal direction is perpendicular to the first horizontal direction. Figure 3 In the embodiment shown in , the second driving member 222 is arranged above the lining plate 223, and a clamping member 224 is provided at one end of the second driving member 222 close to the lining plate 223. The second driving member 222 is used to drive the clamping member 224 to approach the lining plate 223 in the vertical direction (i.e., the Z direction shown in the figure) so that the clamping member 224 can fix the sheet workpiece on the lining plate 223; or drive the clamping member 224 away from the lining plate 223 to release the sheet workpiece.

[0044] So, like Figure 1As shown, when the sheet workpiece is being extracted, when the clamping member 224 fixes the sheet workpiece on the lining plate 223, the first driving member 210 can drive the extracting assembly 220 to move along the first horizontal direction to extract the sheet workpiece from the product, thereby being able to smoothly extract the sheet workpiece from the product, thereby preventing the sheet workpiece from being scattered around and difficult to collect.

[0045] In one embodiment of the present application, Figure 3 As shown, the sheet workpiece 70 is a plug sheet 70 used in assembling a high-voltage relay of a vehicle charging gun, and the plug sheet 70 has a plug hole. In order to better fix the plug sheet 70 on the lining plate 223, the clamping member 224 is provided with a plug post 225 at the end close to the lining plate 223. The plug post 225 is used to be inserted into the plug hole of the plug sheet 70 when the plug sheet 70 is placed on the lining plate 223, so that the plug sheet 70 will not slide relative to the clamping member 224, so that the plug sheet 70 can be fixed on the lining plate 223 more firmly.

[0046] exist Figure 3 In the embodiment shown in FIG. 1 , the number of plugs 225 is two, because Figure 3 In the embodiment, the plug sheet 70 has two plug holes, so a plug rod 225 is inserted into a corresponding plug hole. It can be understood that the number of plug rods 225 is not limited, which depends on the number of plug holes opened by the plug sheet 70. Of course, even if there are no plug holes opened on other types of sheet workpieces 70, the plug rod 225 can be set to abut against the sheet workpiece 70, so that the sheet workpiece 70 can be fixed on the lining plate 223. There are no special limitations on the above.

[0047] For further information, please refer to Figure 3In order to make the sheet workpiece 70 automatically fall down after the clamping member 224 releases the sheet workpiece 70, the lining plate 223 includes a first plate 2231 and a second plate 2232 connected to each other, one end of the second plate 2232 in the second horizontal direction is connected to the first plate 2231, and the other end is suspended, and the thickness of the second plate 2232 is less than the thickness of the first plate 2231, so that a step is formed at the connection position between the first plate 2231 and the second plate 2232. And the width dimension of the second plate 2232 in the first horizontal direction is less than the width dimension of the first plate 2231 in the second horizontal direction. In this way, when the size of the sheet workpiece 70 is large (that is, the projected area of ​​the sheet workpiece 70 on the second plate 2232 is larger than the second plate 2232), the sheet workpiece 70 can only be fixed on the lining plate 223 when it is abutted by the clamping member 224. When the second driving member 222 drives the clamping member 224 upward and away from the lining plate 223, the lining plate 223 does not clamp the sheet workpiece 70 sufficiently, so that the sheet workpiece 70 will automatically fall under the action of gravity, thereby eliminating the need to use auxiliary mechanisms (such as clamps or three-axis transfer modules, etc.) to transfer the extracted sheet workpiece 70 to a specified position, thereby simplifying the overall structure of the extraction device 10, saving the space occupied by the extraction device 10, and saving the manufacturing cost of the extraction device 10.

[0048] It is worth noting that in some cases, there are usually multiple sheet-like workpieces on the product, and the size specifications and locations of each sheet-like workpiece are different. Figure 1 and Figure 2 In order to make the extraction assembly 220 adaptable to extract sheet workpieces of different sizes or at different positions, the connection seat 221 optionally includes a base plate 2211 and a connection member 2212, and the extraction mechanism 200 further includes a third driving member 230, wherein the base plate 2211 is slidably disposed on the machine 100 and connected to the first driving member 210, one end of the connection member 2212 is slidably connected to the base plate 2211, specifically, it is slidably disposed on the side of the base plate 2211 away from the machine 100, and the other end is suspended relative to the machine 100, and the second driving member 222 and the lining plate 223 are disposed on the end of the connection member 2212 away from the base plate 2211 and suspended. The third driving member 230 is disposed on the base plate 2211 and the connection member 2212, and is used to drive the connection member 2212, the second driving member 222, the clamping member 224 and the lining plate 223 to move relative to the base plate 2211 along the first horizontal direction.

[0049] In this way, when it is necessary to extract sheet workpieces of different sizes or located at different positions, it is only necessary to drive the third driving member 230 to drive the connecting member 2212, the second driving member 222, the clamping member 224 and the lining plate 223 to move a certain distance along the first horizontal direction, and the clamping member 224 can fix the sheet workpiece on the lining plate 223 at different positions, and then the first driving member 210 drives the extraction mechanism 200 to move as a whole along the first horizontal direction, so that sheet workpieces of different sizes or located at different positions in the first horizontal direction can be extracted. Therefore, there is no need to replace the equipment, which facilitates the user's operation.

[0050] It is understandable that the first driving member 210 , the second driving member 222 and the third driving member 230 may all be driving sources such as a cylinder or an electric cylinder, which is not limited here.

[0051] In a preferred embodiment, a hard stop assembly 2213 is provided at one end of the base plate 2211 away from the first driving member 210, and the hard stop assembly 2213 is used to limit the moving range of the connecting member 2212 when the connecting member 2212 moves relative to the base plate 2211. This is because the third driving member 230 is a cylinder and when the third driving member 230 drives the connecting member 2212 to move relative to the base plate 2211, the connecting member 2212 may move too much due to the high air pressure and exceed the maximum prescribed stroke. By providing the hard stop assembly 2213, the connecting member 2212 can be abutted against the connecting member 2212 when the connecting member 2212 is about to exceed the maximum stroke, thereby limiting the moving range of the connecting member 2212 and preventing the connecting member 2212 from sliding off the base plate 2211.

[0052] See also Figure 1 and Figure 4 In one embodiment, the clamping mechanism 300 includes a mounting plate 310, a fourth driving member 320 and a clamping member 330. The mounting plate 310 is disposed on the machine platform 100, and one end thereof is suspended relative to the machine platform 100. The fourth driving member 320 is mounted on the end of the mounting plate 310 suspended relative to the machine platform 100. The clamping member 330 is connected to the fourth driving member 320. The fourth driving member 320 can also be a driving source such as a cylinder or an electric cylinder. The clamping member 330 can move in a vertical direction under the drive of the fourth driving member 320, so that the extraction component 220 can clamp the product when extracting the sheet workpiece from the product, thereby preventing the product from shaking at will, and further increasing the success rate of extraction.

[0053] Furthermore, in order to prevent the pressing member 330 from crushing the product when pressing the product, the end of the pressing member 330 away from the fourth driving member 320 is provided with an anti-collision block 340 for abutting against the product. The material of the anti-collision block 340 is preferably non-metallic material, such as plastic material or polyurethane material, so that when the anti-collision block 340 abuts against the product, the product will not be crushed due to the excessive hardness of the anti-collision block 340. Figure 4 In the embodiment shown in , there are two anti-collision blocks 340 . Of course, the number of anti-collision blocks 340 is not limited, and there may be more anti-collision blocks 340 , which is not limited here.

[0054] It should be noted that when the product is manually compressed, the extraction device 10 of the above embodiment may not be provided with the compression mechanism 300. However, it is obvious that after the compression mechanism 300 is provided, the product can be automatically compressed without the need for manual compression, thereby saving labor and improving the degree of automation of the extraction device 10.

[0055] Combination Figure 1 and Figure 5 As shown, after the clamping member 224 of the extraction mechanism 200 releases the sheet workpiece, the sheet workpiece can fall along a fixed path under the action of its own gravity. In order to further prevent the sheet workpiece from being scattered around due to the influence of the external environment (such as wind force, etc.) when falling, making it difficult to collect the sheet workpiece, the extraction device 10 also includes a material receiving member 400, which is arranged beside the machine 100 and below the extraction assembly 220. The material receiving member 400 is a long cylindrical structure, and is provided with a material channel 401 that runs through the opposite ends of itself in the vertical direction. In this way, when the clamping member 224 releases the sheet workpiece, the sheet workpiece can fall along the material channel 401 to the bottom of the material receiving member 400 when it falls under the action of its own gravity, thereby further preventing the sheet workpiece from being scattered around after being extracted.

[0056] In order to count the sheet workpieces falling into the receiving member 400 and to count the number of sheet workpieces extracted, based on the above embodiment, the receiving member 400 is further provided with a counting assembly 500, which is used to count the sheet workpieces passing through the material channel 401. In a specific embodiment, the counting assembly 500 is a set of opposite-beam photoelectric sensors, which include a transmitting part 510 and a receiving part 520 respectively arranged on the opposite side walls of the receiving member 400, wherein the transmitting part 510 is used to emit light, and the receiving part 520 receives light. When the sheet workpiece falls, it will inevitably pass through the above light. Each time the light passes through, it will block the light emitted by the transmitting part 510 so that the receiving part 520 receives the light. By automatically recording the number of times the receiving part 520 receives the light, the number of sheet workpieces extracted from the material channel 401 can be obtained. Furthermore, in order to more accurately count the number of sheet workpieces that fall into the material channel 401 and are pulled out, the number of counting components 500 can be set to more than two groups, so that the number of sheet workpieces that fall into the material channel 401 and are pulled out can be counted more than twice to obtain a more accurate number of sheet workpieces.

[0057] In addition, in order to collect the sheet workpieces in a centralized manner so as to facilitate the subsequent handling of the collected sheet workpieces, the extraction device 10 also includes a material receiving box 600 disposed below the material receiving member 400. When the sheet workpieces in the material receiving box 600 reach a certain number, the counting component 500 can remind the operator to replace the material receiving box 600, so as to facilitate the recycling of the sheet workpieces. Specifically, the material receiving box 600 has a receiving cavity 601 connected to the material channel 401, and the receiving cavity 601 is used to accommodate the sheet workpieces falling from the material channel 401, and the opposite side walls of the material receiving box 600 are provided with handles, so that the sheet workpieces to be extracted can be conveniently handled after all fall into the material receiving box 600. And because the material receiving box 600 is disposed below the material receiving member 400, the distance between the material receiving box 600 and the extraction mechanism 200 is relatively far, so that the space in the vertical direction can be fully utilized, and the space occupied by the extraction device 10 as a whole in the horizontal direction can be reduced.

[0058] It can be seen that the extraction device 10 provided in the embodiment of the present application can smoothly pull the sheet workpiece out of the product; and when the clamping member 224 releases the sheet workpiece, the sheet workpiece can fall into the material receiving box 600 along the material channel 401 of the material receiving member 400 under the action of gravity, which can not only save the overall space occupied by the equipment, but also overcome the problem in the prior art of using a cylinder to hard-top the sheet workpiece, causing the sheet workpiece to be scattered everywhere and difficult to collect, thereby improving production efficiency.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
