Description

Technical Field

[0001] The utility model relates to the field of manufacturing technology, in particular to a welding fixing device. Background Art

[0002] The semiconductor industry places high demands on welding processes. For example, any slight deformation or positional deviation during welding can lead to poor weld quality, potentially causing leaks, short circuits, and other issues, impacting the overall performance and service life of the product.

[0003] Traditional manual welding methods rely on the operator's skill level and experience, and it is difficult to ensure that each weld can achieve the ideal precision standard. Welding gaps that are difficult to detect with the naked eye are prone to occur, which may cause leakage and other problems in the equipment produced during use.

[0004] Automated welding technology, particularly robotic welding, is becoming increasingly widespread. For example, current robotic welding methods require a human operator to manually place the product to be welded on a welding fixture. After the product is placed on the fixture, a human operator, holding a handheld debugger, simulates walking along each predetermined welding position on the product (this is known as the debugging process). This debugging process allows the robot to learn and record the welding path so that it can subsequently perform precise welding operations according to this path.

[0005] However, the inventors found that according to the current robot welding method, when replacing the product, the actual position of the product may be slightly offset due to various factors. This offset will cause the robot to have position deviation when welding according to the preset path, thereby affecting the welding quality.

[0006] Therefore, in the existing technology, each time a new product to be welded is replaced, the above debugging process needs to be repeated to ensure that the robot can accurately identify and weld to each predetermined welding position. In the mass production process of products, the existing technology method increases the welding debugging time and reduces production efficiency. Utility Model Content

The second abutting portion is located between the bottom surface of the second connecting portion and the top surface of the base.

[0010] According to some embodiments, the clamping member further includes at least two operating portions. One end of the operating portion is fixed on the connecting member, and the other end of the operating portion is fixedly connected to the top surface of the first abutting portion. The at least two operating portions respectively push the top surface of the first abutting portion along a preset pushing direction, so that the distance between the bottom surface of the first abutting portion and the top surface of the base is reduced to clamp the product to be welded. The preset pushing direction is the direction perpendicular to the base.

[0016] Beneficial effects

[0017] The staff can place the product to be welded on the base and push the product to be welded so that the side surface of the product to be welded abuts against the side surface of the positioning member. And, the first abutting portion of the first clamping member can move towards the top surface of the base under the control of the staff until the bottom surface of the first abutting portion abuts against the top surface of the product to be welded and the first abutting portion and the base can clamp the product to be welded. This enables the product to be welded to be fixed in a preset standard position, and when welding the product to be welded, the product to be welded will not shift because it is clamped.

[0018] In the embodiments of the present application, for products to be welded of the same size and type, each product to be welded will be clamped and fixed in the same preset standard position for the robot to perform welding. This eliminates the need to perform a robot debugging process every time the product to be welded is changed. Thus, it only needs to be debugged once when products to be welded of each size are placed in the corresponding preset standard positions. Applying the present application in the mass production manufacturing process is beneficial to shortening the welding debugging time, improving the product welding efficiency, and thus improving the production efficiency.

[0029] The technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative efforts fall within the scope of protection of this application.

[0030] Figure 1 The overall structure of the welding fixing device according to the embodiment of this application is shown. Referring to Figure 1 The welding fixing device provided by the embodiment of this application includes a base 1, a positioning member 2, a connecting member 3, and a first clamping member 4.

[0031] Referring to Figure 1 or Figure 2 The base 1 bears the product 0 to be welded, and when the product 0 to be welded is placed on the base 1, the top surface of the base 1 abuts against the bottom surface of the product 0 to be welded. The side surface of the positioning member 2 is perpendicular to the top surface of the base 1, and the bottom surface of the positioning member 2 is fixedly connected to the base 1. When the product 0 to be welded is placed on the base 1, the side surface of the positioning member 2 abuts against the side surface of the product 0 to be welded to limit the position of the product 0 to be welded.

[0032] According to an exemplary embodiment, referring to Figure 1 , Figure 2 and Figure 3 the positioning member 2 may include a first side abutting portion 21 and a second side abutting portion 22. The bottom surface of the first side abutting portion 21 is fixed on the top surface of the base 1, and the side surface of the first side abutting portion 21 is perpendicular to the top surface of the base 1.

[0033] The bottom surface of the second side abutting portion 22 is also fixed on the top surface of the base 1, and the side surface of the second side abutting portion 22 is also perpendicular to the top surface of the base 1.

[0034] When the product 0 to be welded is placed on the base 1, the first side surface of the product 0 to be welded abuts against the side surface of the first side surface abutting portion 21, and the second side surface of the product 0 to be welded abuts against the side surface of the second side surface abutting portion 22. And the first side surface and the second side surface are two adjacent side surfaces of the product 0 to be welded.

[0035] Exemplarily, when the first side surface and the second side surface of the product 0 to be welded are perpendicular and connected (that is, the included angle formed by the first side surface and the second side surface is 90°), the side surface of the first side surface abutting portion 21 is perpendicular to the side surface of the second side surface abutting portion 22, and respectively abut against the first side surface and the second side surface of the product 0 to be welded.

[0036] The connecting member 3 is parallel to the bottom surface of the base 1, and the connecting member 3 is also fixedly connected to the positioning member 2. For example, the bottom surface of the connecting member 3 is fixedly connected to the top surface of the positioning member 2, and the bottom surface of the connecting member 3 and the top surface of the connecting member 3 are parallel to the bottom surface of the base 1, that is, the connecting member 3 is located above the base 1 and is parallel to the base 1.

[0037] The first clamping member 4 is connected to the connecting member 3. The first clamping member 4 includes a first abutting portion 41, and the first abutting portion 41 is located between the bottom surface of the connecting member 3 and the top surface of the base 1. And the bottom surface of the first abutting portion 41 is parallel to the top surface of the base 1 to form a placement area for placing the product 0 to be welded between the bottom surface of the first abutting portion 41 and the top surface of the base 1. The first abutting portion 41 of the first clamping member 4 can move towards the top surface of the base 1 to clamp the product 0 to be welded.

[0038] That is, a region for accommodating the product 0 to be welded is formed between the inner side surface of the first side surface abutting portion 21, the inner side surface of the second side surface abutting portion 22, the top surface of the base 1, and the bottom surface of the first abutting portion 41.

[0039] When the product 0 to be welded is placed on the base 1, the worker can push the product 0 to be welded so that the first side surface of the product 0 to be welded abuts against the inner side surface of the first side surface abutting portion 21, the second side surface abuts against the inner side surface of the second side surface abutting portion 22, and the bottom surface of the product 0 to be welded abuts against the top surface of the base 1, so as to push the product 0 to be welded to a preset standard welding position. Then the worker can control the first abutting portion 41 of the first clamping member 4 to move towards the top surface of the base 1, so that the product 0 to be welded is clamped by the base 1 and the first abutting portion 41 and cannot move, thereby fixing the product 0 to be welded at the preset standard welding position, that is, fixing it at the preset standard position. And when the robot welds the product 0 to be welded, the product 0 to be welded will not shift either.

[0040] In the embodiment of the present application, for the products 0 to be welded with the same size and type, each product 0 to be welded will be clamped and fixed at the same preset standard position so that the robot can perform welding. In this way, it is not necessary to perform a robot debugging process every time the product 0 to be welded is replaced, but only one debugging is required when the products 0 to be welded of each size are placed at the corresponding preset standard positions. Applying the present application in the mass production manufacturing process is beneficial to shortening the welding debugging time, improving the product welding efficiency, and further improving the production efficiency.

[0041] Optionally, referring to Figure 1 、 Figure 2 and Figure 3 The first clamping member 4 not only includes a first abutting portion 41, but may also include at least two operating portions 42. The at least two operating portions 42 are respectively fixed on the positioning member 2. That is, one end of each operating portion 42 is fixed on the positioning member 2, and the other end of each operating portion 42 is fixedly connected to the top surface of the first abutting portion 41.

[0042] Exemplarily, taking the first clamping member 4 including two operating portions 42 as an example for illustration. One end of one operating portion 42 is fixed on the positioning member 2, and the other end of this operating portion 42 passes through the positioning member 2 and is fixed on the top surface of the first abutting portion 41. One end of the other operating portion 42 is also fixed on the positioning member 2, and the other end of this other operating portion 42 passes through the positioning member 2 and is fixed on the top surface of the first abutting portion 41.

[0043] The two operating portions 42 can simultaneously apply the same magnitude of force to different positions of the first abutting portion 41 in the same direction. For example, when the staff pushes the first abutting portion 41 to clamp the product 0 to be welded, the two operating portions 42 can respectively push the first abutting portion 41 in the preset pushing direction simultaneously and with the same magnitude of force, so that the distance between the bottom surface of the first abutting portion 41 and the top surface of the base 1 is reduced until the product 0 to be welded is clamped. The preset pushing direction is the direction vertically pointing to the base 1.

[0044] Optionally, the first abutting portion 41 can also be pulled by the two operating portions 42 to expand the distance between the bottom surface of the first abutting portion 41 and the top surface of the base 1, so as to facilitate the staff to remove the welded product.

[0045] In this way, by simultaneously pushing or pulling the first abutting portion 41 through at least two operating portions 42, the probability of the first abutting portion 41 rotating in the horizontal direction during the process of the operating portion 42 controlling the movement of the first abutting portion 41 can be reduced. In the embodiment of the present application, by simultaneously pushing or pulling the first abutting portion 41 through at least two operating portions 42, the first abutting portion 41 can perform a linear motion in the vertical direction, so that the product 0 to be welded can be stably clamped.

[0046] Optionally, referring to Figure 1 , Figure 2 and Figure 3 , the first abutting portion 41 may specifically be an abutting plate. The structure of the operating portion 42 may be a cylinder telescopic structure or a hydraulic telescopic structure, which is not limited herein.

[0047] Optionally, when the structure of the operating portion 42 is a cylinder telescopic structure, the operating portion 42 may include a cylinder block, a piston and a piston rod.

[0048] The cylinder block, as the main body for bearing and guiding, is responsible for connecting the external air supply system or pressure source. The cylinder block is fixedly connected to the top surface of the connecting member 3. The piston is located inside the cylinder block. The piston rod is a motion execution element, one end of which is fixedly connected to the top surface of the first abutting portion 41, and the other end of the piston rod is slidably matched with the piston inside the cylinder block through structures such as a seal.

[0049] The external air supply system can input or release compressed gas into the cylinder block. Due to the change of the gas pressure inside the cylinder block, the piston performs a linear motion inside the cylinder block, so that the piston rod, driven by the piston, also performs a linear telescopic motion, and then pushes or pulls the first abutting portion 41, so that the first abutting portion 41 can perform a linear motion in the vertical direction. The vertical direction refers to the direction perpendicular to the top surface of the base 1 and pointing to the bottom surface of the base 1.

[0050] Optionally, the operating portion 42 can also adjust the initial position of the piston to adjust the maximum distance that the piston rod can extend or retract.

[0051] Exemplarily, the operating portion 42 may further include a limit post and a limit nut. The piston rod is a threaded rod. One end of the piston rod is connected to the top surface of the first abutting portion 41, the other end of the piston rod is arranged in cooperation with the piston, extends out of the cylinder block, and passes through the limit post. The limit post abuts against the outer wall of the cylinder block. And the limit nut is arranged on the limit rod to limit the position of the limit post on the limit rod.

[0052] Exemplarily, when the limit nut is in the first preset position, the initial position of the piston is at the edge position of the cylinder block of the cylinder and close to the top surface of the connecting member 3. In this case, the maximum distance that the piston rod can extend or retract is L1.

[0053] The staff adjusts the limit nut to move the limit post towards the position of the cylinder block. And when the limit nut is in the second preset position, the initial position of the piston is at the middle position of the cylinder block of the cylinder, so that the maximum distance that the piston rod can extend or retract is L2. The L2 is equivalent to half of L1.

[0054] In this way, by adjusting the limit nut above the cylinder block of the cylinder, the initial position of the piston can be adjusted, so that the maximum distance that the piston rod can extend or retract can be adjusted. Furthermore, the welding fixing device of the present application can be adapted to more sizes of products to be welded 0.

[0055] Optionally, referring to Figure 1 、 Figure 2 and Figure 3 , the first side abutting portion 21 can specifically be a first baffle, and the second side abutting portion 22 can specifically be a second baffle. The base 1 is horizontally arranged, and the first baffle and the second baffle are vertically arranged. That is, the bottom end of the first baffle is fixed on the top surface of the base 1. The bottom end of the second baffle is also fixed on the top surface of the base 1. The right end of the first baffle is connected to the left end of the second baffle, and an included angle is formed between the first baffle and the second baffle, and the angle of the included angle is a preset angle.

[0056] Optionally, referring to Figure 1 、 Figure 2 and Figure 3 , the connecting member 3 can include a first connecting portion 31 and a second connecting portion 32. One end of the first connecting portion 31 is fixed on the top surface of the first side abutting portion 21, and the other end of the first connecting portion 31 is fixed on the top surface of the second side abutting portion 22. And the bottom surface of the first connecting portion 31 is parallel to the top surface of the base 1.

[0057] The second connecting portion 32 is fixed on the top surface of the second side abutting portion 22, and the bottom surface of the second connecting portion 32 is parallel to the top surface of the base 1.

[0058] Exemplarily, the first connecting portion 31 can be a horizontally arranged first connecting plate, and the second connecting portion 32 can be a horizontally arranged second connecting plate.

[0059] The first end of the first connecting plate is fixed on the top surface of the first side abutting portion 21, the second end of the first connecting plate is fixed on the top surface of the second side abutting portion 22, and the third end and the fourth end of the first connecting plate are suspended. The fourth end is close to the inner side surface of the second side abutting portion 22 and far from the outer side surface of the second side abutting portion 22.

[0060] Wherein, the first end, the second end, the third end and the fourth end are respectively the four side ends of the first connecting plate, and the four side surfaces are the first end, the second end, the third end and the fourth end in sequence according to a preset clockwise direction. That is to say, the first end and the second end are two adjacent ends of the first connecting plate.

[0061] Exemplarily, the second connecting plate is on the same horizontal line as the first connecting plate, and one end of the second connecting plate is fixed on the top surface of the second side abutting portion 22. The bottom surface of the second connecting plate is parallel to the top surface of the base 1.

[0062] The opposite end of the second connecting plate is arranged away from the second side abutting portion 22, and the opposite end of the second connecting plate is close to the inner side surface of the second side abutting portion 22 and far from the outer side surface of the second side abutting portion 22. And the opposite end of the second connecting plate is the end opposite to one end of the second connecting plate.

[0063] Optionally, as Figure 3 shown, the welding fixing device may further include a second clamping member 6. The second clamping member 6 includes a second abutting portion (not marked in the figure).

[0064] The first clamping member 4 is connected to the first connecting portion 31, and the first abutting portion 41 is located between the bottom surface of the first connecting portion 31 and the top surface of the base 1.

[0065] The second clamping member 6 is connected to the second connecting portion 32, and the second abutting portion is located between the bottom surface of the second connecting portion 32 and the top surface of the base 1.

[0066] The first abutting portion 41 can move towards the top surface of the base 1, and the second abutting portion can also move towards the top surface of the base 1 to clamp the product 0 to be welded.

[0067] A placement area for accommodating the product 0 to be welded is formed among the bottom surface of the first abutting portion 41, the bottom surface of the second abutting portion, the top surface of the base 1, the inner side surface of the first side abutting portion 21 and the inner side surface of the second side abutting portion 22.

[0068] Exemplarily, after placing the product 0 to be welded on the top surface of the base 1, the staff can push the product 0 to be welded to a preset standard position, so that the first side surface of the product 0 to be welded abuts against the inner side surface of the first side surface abutting portion 21, and the second side surface of the product 0 to be welded abuts against the inner side surface of the second side surface abutting portion 22. Then, the staff can also control the first clamping member 4 and the second clamping member 6, so that the first abutting portion 41 and the second abutting portion move respectively in a direction perpendicular to the top surface of the base 1, so as to clamp the product 0 to be welded by the first abutting portion 41, the second abutting portion and the base 1, thereby clamping and fixing the product 0 to be welded at the preset standard position.

[0069] Exemplarily, after placing the product 0 to be welded on the top surface of the base 1, the staff can also uniformly rotate the direction of the welding and fixing device and the product 0 to be welded, so that the first side surface abutting portion 21 rotates to the horizontal direction, and rotates to a position where the product 0 to be welded is above and the first side surface abutting portion 21 is below. Then, the staff pushes the product 0 to be welded in a direction perpendicular to the inner side surface of the second side surface abutting portion 22, so that the product 0 to be welded abuts against the inner side surface of the second side surface abutting portion 22. Then, the staff can control the first abutting portion 41 and the second abutting portion to move towards the base 1 to clamp the product 0 to be welded.

[0070] Optionally, one end of each operating portion 42 of the first clamping member 41 is fixed on the first connecting portion 31, and the other end passes through the first connecting portion 31 and is fixed on the top surface of the first abutting portion 41.

[0071] The second clamping member 42 may further include at least two telescopic operating portions. One end of each telescopic operating portion is fixed on the second connecting portion 32, and the other end passes through the second connecting portion 32 and is fixed on the top surface of the second abutting portion.

[0072] The structure of the second abutting portion and the at least two telescopic operating portions is the same as the structure between the first abutting portion 41 and the at least two operating portions 42 in the above embodiment, and will not be elaborated here.

[0073] Optionally, referring to Figure 1 、 Figure 2 and Figure 3 and

[0074] The staff can control the rotation of the fixing member 5 in the vertical plane so that the other end of the fixing member 5 abuts against the top surface of the product 0 to be welded, thereby fixing the product 0 to be welded.

[0075] Optionally, the rotation angle of the fixing member 5 is 0-90°.

[0076] Optionally, referring to Figure 1 , Figure 2 and Figure 3 , the fixing member 5 may specifically include a manual control part 51, a fixing part 52 and a limiting part 53. One end of the manual control part 51 is fixedly connected to one end of the fixing part 52. Moreover, the end of the manual control part 51 connected to the fixing part 52 is connected to the connecting member 3 and is rotatably connected to the connecting member 3 so that the control part and the fixing part 52 can rotate around the connected end as the center point in the vertical plane. The bottom surface of the fixing part 52 is fixedly connected to the top surface of the limiting part 53.

[0077] Referring to Figure 3 , when the manual control part 51 is rotated to be perpendicular to the top surface of the connecting member 3 (for example, in the initial state of the fixing member 5, the rotation angle is 0), the bottom surface of the limiting part 53 is parallel to the top surface of the base 1, and the bottom surface of the limiting part 53 is used to abut against the top surface of the product 0 to be welded, so that the limiting part 53 and the base 1 can fix the product 0 to be welded.

[0078] When the manual control part 51 is rotated to be parallel to the top surface of the connecting member 3 (for example, the situation after the manual control part 51 is rotated counterclockwise by 90° in the initial state of the fixing member 5), the bottom surface of the limiting part 53 is perpendicular to the top surface of the base 1, and the bottom surface of the limiting part 53 does not abut against the top surface of the product 0 to be welded.

[0079] The staff can turn the manual control part 51 so that the manual control part 51, the fixing part 52 and the limiting part 53 rotate as a whole in the vertical plane. And the staff turning the manual control part 51 can make the bottom surface of the limiting part 53 abut against the top surface of the product 0 to be welded, so that the product 0 to be welded is also clamped by the limiting part 53 and the base 1, to further reduce the probability of the position of the product 0 to be welded shifting.

[0080] Optionally, when the connecting member 3 includes a first connecting part 31 and a second connecting part 32, the fixing member 5 may include a first fixing member, a second fixing member, a third fixing member, a fourth fixing member, a fifth fixing member and a sixth fixing member.

[0081] The first fixing member and the second fixing member are fixed on the first connecting portion 31. The third fixing member, the fourth fixing member, the fifth fixing member and the sixth fixing member are fixed on the second connecting portion 32.

[0082] Among them, the structures of the first fixing member, the second fixing member, the third fixing member, the fourth fixing member, the fifth fixing member and the sixth fixing member are the same as those of the fixing member 5 described above, and will not be elaborated here.

[0083] It should be noted that the heights of the limiting portions 53 of the respective fixing members 5 may be the same or different, and can be adjusted adaptively according to the size of the product 0 to be welded. For example, the heights of the limiting portions of the first fixing member, the second fixing member, the third fixing member, the fourth fixing member, the fifth fixing member and the sixth fixing member are all the same; or the heights of the limiting portions of the first fixing member, the second fixing member, the third fixing member and the fourth fixing member are the same, and are used to fix the product 0 to be welded with a first preset height dimension, and the heights of the limiting portions of the fifth fixing member and the sixth fixing member are the same and different from the heights of the limiting portions such as the first fixing member, and are used to fix the product 0 to be welded with a second preset height dimension.

[0084] Based on the above embodiments, an example is provided in an embodiment of the present application to illustrate the working process of welding a product using this welding fixing device. In the initial state, the bottom surface of the base 1 of this welding fixing device is fixed on an external positioner, and the bottom surface of the base 1 is in a horizontal state (the external positioner can control the rotation of the welding fixing device). As Figure 1 shown.

[0085] The staff connects the air source to each operation portion 42 of this welding fixing device. Then the staff places the product 0 to be welded on the base 1 of this welding fixing device, as Figure 2 shown.

[0086] Then the staff controls the rotation of the positioner, so that the base 1 of the welding fixing device changes from a horizontal state to a vertical state, and the side surface of the first side abutting portion 21 changes from a vertical state to a horizontal state, as Figure 4 shown.

[0087] Then the staff can push the product 0 to be welded in the direction of the second side abutting portion 22, so that the second side of the product 0 to be welded abuts against the side surface of the second side abutting portion 22.

[0088] After that, the staff can control the operating part 42 of the first clamping member 4 and the telescopic operating part of the second clamping member 6, so that the operating part 42 of the first clamping member 4 and the telescopic operating part of the second clamping member 6 can push the first abutting part 41 and the second abutting part, thereby pushing the product 0 to be welded, so that the first abutting part 41 and the second abutting part respectively abut against the product 0 to be welded and the product 0 to be welded abuts against the base 1, so that the product 0 to be welded is fixed at a preset standard position by the first abutting part 41, the second abutting part and the base 1.

[0089] Alternatively, after the staff abuts the second side surface of the product 0 to be welded against the side surface of the second side surface abutting part 22, the staff can also manually turn the handheld control part of the fixing member 5, so that the fixing member 5 rotates, and the limiting part 53 of the fixing member 5 abuts against the product 0 to be welded, thereby fixing the product 0 to be welded at a preset standard position by the limiting part 53 and the base 1.

[0090] Alternatively, after the staff abuts the second side surface of the product 0 to be welded against the side surface of the second side surface abutting part 22, the staff can control the operating part 42 of the first clamping member 4 and the telescopic operating part of the second clamping member 6, so that the first abutting part 41 and the second abutting part respectively abut against the product 0 to be welded and the product 0 to be welded abuts against the base 1. And then the staff can manually turn the manual control part 51 of the fixing member 5, so that the product 0 to be welded abuts against the limiting part 53 and the base 1 respectively, thereby fixing the product 0 to be welded at a preset standard position by the first abutting part 41, the second abutting part, the limiting part 53 and the base 1.

[0091] After the product 0 to be welded is fixed at a preset standard position, the welding robot can weld the product 0 to be welded.

[0092] After welding is completed, the positioner can rotate to the initial state (that is, rotate from the state shown in Figure 4 to the state shown in Figure 2 ), so that the base 1 of the welding fixing device changes from a vertical state to a horizontal state. And after the positioner rotates, the staff can control the operating part 42 and the telescopic operating part and / or the staff can manually turn the manual control part 51 to release the product 0 to be welded, so as to facilitate the staff to take away the welded product.

[0093] Finally, it should be noted that the above are only the preferred embodiments of the present application and are not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions of the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
