Description

Technical Field

[0001] The present application relates to the technical field of battery manufacturing, and in particular to a welding tool and a welding device. Background Art

[0002] Energy conservation and emission reduction are the key to the sustainable development of the automobile industry. Electric vehicles have become an important part of the sustainable development of the automobile industry due to their advantages of energy conservation and environmental protection. For electric vehicles, battery technology is an important factor related to their development. The battery pack of new energy electric vehicles is an energy storage system for pure electric vehicles and plug-in hybrid vehicles. The interior is composed of a combination of multiple cores and the exterior is supported by a box. In order to reduce the cost of the box, the bottom surface of the box is usually constructed as a thin plate with a small thickness (for example, 1.5 mm). Because the plane size of the thin plate is large and the thickness is thin, it is affected by gravity in a free state, and has a deformation tendency of being concave in the middle, resulting in unevenness. Utility Model Content

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the present application is to provide a welding tool and a welding device.

[0004] The embodiment of the first aspect of the present application provides a welding tool, including: a tool body; at least one support member, at least one support member is arranged on the tool body, and is used to support a plate-shaped workpiece to be welded; and at least one side push assembly, at least one side push assembly is arranged on the tool body, and is used to deform a frame workpiece to be welded with the plate-shaped workpiece. Each side push assembly includes: a base, the base is fixed on the tool body; a pressure block, the pressure block is arranged on the base; and a push member, the push member is connected to the pressure block, and is used to push the pressure block relative to the base toward the frame workpiece, so that the pressure block applies pressure to the frame workpiece to deform the frame workpiece.

[0005] In the technical solution of the embodiment of the present application, by providing a side push assembly, the frame workpiece can be pushed toward the inside of the frame as a whole, so that the frame workpiece is bent inward. When the frame workpiece is bent inward, the frame workpiece and the plate-shaped workpiece are welded. After the welding process is completed, the side push assembly can no longer push the frame workpiece, but allow the frame workpiece to rebound. In this way, the plate-shaped workpiece welded to the frame workpiece can be pulled under the action of the frame workpiece rebound force, so that the plate-shaped workpiece is flatter.

[0006] In some embodiments, the push member is configured to keep the pressing block at a preset position relative to the base. When the push member keeps the pressing block at the preset position relative to the base, the pressure applied by the pressing block to the frame workpiece remains unchanged, so that in this case, the deformation degree of the frame workpiece can be kept relatively constant, which is conducive to more stable welding, which is more advantageous in the scenario where the frame workpiece and the plate-shaped workpiece need to be welded for a long time.

[0007] In some embodiments, the base includes a threaded through hole, and the push member includes a push rod with an external thread, the push rod can rotate in the threaded through hole to push the pressing block to move, and the cooperation between the external thread of the push rod and the internal thread of the threaded through hole enables the push rod to keep the pressing block at a preset position. Thus, through the push rod with an external thread and the threaded through hole with an internal thread, not only can the pressing block be pushed to move toward the frame workpiece relative to the base, but also the pressing block can be kept at a preset position relative to the base, the structure is simple, and the operation is convenient.

[0008] In some embodiments, the pressing block includes a limiting protrusion, and each side push assembly also includes a limiting block fixed on the base, and the pressing block and / or the limiting block are configured such that when the pressing block moves toward the frame workpiece until the limiting protrusion abuts against the limiting block, the limiting block prevents the pressing block from continuing to move toward the frame workpiece. Thus, by providing the limiting block, it is possible to prevent the pressing block from over-pressing the frame workpiece and causing excessive deformation of the frame workpiece.

[0009] In some embodiments, each side push assembly further includes an adjustment pad, which is detachably disposed on a surface of the limit block for contacting the limit protrusion. Thus, the maximum extrusion amount of the side push assembly on the frame workpiece can be adjusted for different scenes or different specifications of workpieces to be welded.

[0010] In some embodiments, the pressing block includes a through slot with a closed opening, and the ejector has a head and a neck that cooperate with the through slot, and the radial dimension of the neck is smaller than the radial dimension of the head, so that the neck can move in the closed opening, while the head cannot pass through the closed opening. Thus, the ejector and the pressing block can be assembled and disassembled relatively conveniently, and when the ejector is needed to push the pressing block, the ejector will not separate from the pressing block.

[0011] In some embodiments, at least one side push assembly includes a plurality of side push assemblies respectively arranged at a plurality of edges of the tooling body, and for each edge of the tooling body, there is at least one side push assembly arranged at the middle position of the edge. Thus, the side push assembly arranged at the middle position of the edge of the tooling body can push up the middle position of the frame workpiece, thereby achieving a better deformation effect of the frame workpiece.

[0012] In some embodiments, the welding tool further includes a pressing assembly, which includes: a bracket, which is fixed to the tool body; and a pressing arm, which can move between a first position and a second position relative to the bracket, in which the pressing arm presses against the frame workpiece to fix the frame workpiece, and in which the pressing arm is separated from the frame workpiece to release the frame workpiece. Thus, when welding, the pressing arm of the pressing assembly presses against the frame workpiece, which can better fix the frame workpiece and prevent it from shifting, thereby facilitating the improvement of welding quality.

[0013] In some embodiments, the welding tool further comprises at least one suction cup, which is disposed on the tool body and is used to absorb the plate-like workpiece when the plate-like workpiece is supported on at least one support member. Thus, when welding, the plate-like workpiece can be better fixed by the suction cup to prevent it from shifting, thereby facilitating improving the welding quality.

[0014] In some embodiments, at least one support member includes: a support surface for contacting a plate-like workpiece; and a support column for connecting the support surface and the tooling body, and the length of the support column can be adjusted. Thus, when, for example, it is necessary to weld a plate-like workpiece to a frame workpiece of different thicknesses, by adjusting the length of the support column, the height of the plate-like workpiece supported on the support member can be adjusted to align with the frame workpiece of different thicknesses, thereby being able to adapt to different workpieces to be welded.

[0015] The embodiment of the second aspect of the present application provides a welding device, which includes: the welding jig according to the embodiment of the first aspect of the present application, which is used to carry the workpiece to be welded; and a welding machine, which is used to weld the workpiece to be welded carried on the welding jig. Because the welding jig has a side push assembly, the frame workpiece can be pushed toward the inside of the frame as a whole, so that the frame workpiece bends inward. When the frame workpiece is bent inward, the welding machine welds the frame workpiece and the plate-like workpiece. After the welding process is completed, the side push assembly can no longer push the frame workpiece, but allows the frame workpiece to rebound. In this way, the plate-like workpiece welded on the frame workpiece can be pulled under the action of the rebound force of the frame workpiece, thereby making the plate-like workpiece smoother.

[0016] The above description is only an overview of the technical solution of the present application. In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the contents of the specification. In order to make the above and other purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are listed below.

[0027] The following embodiments of the technical solution of the present application are described in detail in conjunction with the accompanying drawings.

In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0030] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of the associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone.

[0034] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0035] When manufacturing a battery pack, a box for accommodating the battery cells can be manufactured by welding a thin plate to a frame. The frame can provide a certain degree of support and fixation for the thin plate. As mentioned above, due to the large planar dimensions and thin thickness of the thin plate, it is affected by gravity in a free state and has a tendency to deform concave in the middle. Even if the thin plate is welded to the frame, it will still have a tendency to deform concave in the middle under the action of gravity, which is undesirable. For example, Figure 1 is a schematic diagram of a workpiece 100 to be welded. The workpiece 100 to be welded may be, for example, a battery pack body. Figure 1 As shown, the workpiece 100 to be welded includes a plate-shaped workpiece 101 and a frame workpiece 102 . Before welding, the two are two separate components.

[0036] In the related art, the principle of thermal expansion and contraction can be applied to heat the thin plate before welding so that it expands and stretches along the plane direction of the thin plate. Welding is performed in the heated state. After welding is completed, the thin plate cools and contracts. The rigidity of the frame is used to limit the contraction of the thin plate, so that the thin plate is flattened as much as possible under the tension of the frame. However, this solution is difficult to avoid radiant heating of the frame during actual operation, causing the frame to also expand due to heat, and shrink and deform in the length direction of the box after cooling, which ultimately makes it difficult to control the size of the box.

[0037] In view of this, an embodiment of the present application provides a welding tool. By providing a side push assembly, the frame workpiece can be pushed toward the inside of the frame as a whole, so that the frame workpiece is bent inward. When the frame workpiece is bent inward, the frame workpiece and the plate-shaped workpiece are welded. After the welding process is completed, the side push assembly can no longer push the frame workpiece, but allow the frame workpiece to rebound. In this way, the plate-shaped workpiece welded to the frame workpiece can be pulled under the action of the rebound force of the frame workpiece, so that the plate-shaped workpiece is flatter.

[0038] The welding tool disclosed in the embodiment of the present application can be applied to the production and manufacturing of battery packs, for example, to clamp the box body during welding of the battery pack box body. In addition, the welding tool disclosed in the embodiment of the present application can also be applied in other fields to weld thin plate products.

[0039] The present application provides a welding tool. Referring to the accompanying drawings, Figure 2 is a schematic diagram of placing a workpiece 100 to be welded on a welding tool 200 in some embodiments of the present application, and Figure 3 This is a schematic diagram of the structure of a welding tool 200 according to some embodiments of the present application; Figure 4 A schematic diagram of a side thrust assembly 230 of a welding tool 200 according to some embodiments of the present application; Figure 5 An exploded view of a side thrust assembly 230 of a welding tool 200 according to some embodiments of the present application; Figure 6 A schematic diagram of a suction cup of a welding tool 200 according to some embodiments of the present application; and Figure 7 It is a schematic diagram of a support member of a welding tool 200 according to some embodiments of the present application.

[0040] like Figure 2 As shown, the workpiece 100 to be welded can be placed on the welding tool 200 , and the subsequent welding process can be performed on the welding tool 200 .

[0041] refer to Figure 3 The welding tool 200 includes: a tool body 210; at least one support member 220, at least one support member 220 is disposed on the tool body 210, and is used to support a plate-shaped workpiece to be welded (e.g. Figure 1 and at least one side push assembly 230, at least one side push assembly 230 is disposed on the tooling body 210, for treating the plate-like workpiece (eg Figure 1 The plate-like workpiece 101 shown in the figure is welded to a frame workpiece (eg Figure 1 The frame workpiece 102 shown is deformed.

[0042] Continue to refer Figure 4 and Figure 5 Each side push assembly 230 includes: a base 231, which is fixed on the tooling body 210; a pressure block 232, which is arranged on the base 231; and a push piece 233, which is connected to the pressure block 232 and is used to push the pressure block 232 to move toward the frame workpiece 102 relative to the base 231, so that the pressure block 232 applies pressure to the frame workpiece 102 to deform the frame workpiece 102.

[0043] In an example, the tool body 210 may be a frame or a platform.

[0044] Since the plate-like workpiece 101 is usually thin, the support member 220 can support the plate-like workpiece 101 to prevent the plate-like workpiece 101 from shaking violently during the welding process. Figure 3In the example shown, the welding tool 200 may include five support members 220, which are arranged at intervals, for example, one support member 220 is arranged at the center of the welding tool 200, and the other four support members 220 are arranged near the four corners of the welding tool 200. It will be understood that any number of support members 220 may be provided according to actual conditions, and the specific arrangement positions of the support members 220 are not limited.

[0045] The side push assembly 230 is used to push and deform the frame workpiece 102. The base 231 of the side push assembly 230 can be fixed on the tooling body 210 by screws, welding or other methods. The pressure block 232 can move on the upper surface of the base 231. The push piece 233 can be connected to the pressure block 232 by, for example, a threaded connection or a snap connection, and is used to push the pressure block 232 relative to the base 231 toward the frame workpiece 102, so that the pressure block 232 applies pressure to the frame workpiece 102 to deform the frame workpiece 102. In the example, the push piece 233 can be driven by an external force, and the external force can come from a motor or a cylinder.

[0046] Thus, the side push assembly 230 can push the frame workpiece 102 toward the inside of the frame as a whole, so that the frame workpiece 102 bends inward. When the frame workpiece 102 is bent inward, the frame workpiece 102 and the plate-like workpiece 101 are welded. After the welding process is completed, the side push assembly 230 can no longer push the frame workpiece 102, but allow the frame workpiece 102 to rebound. In this way, the plate-like workpiece 101 welded on the frame workpiece 102 can be pulled under the action of the rebound force of the frame workpiece 102, so that the plate-like workpiece 101 is flatter.

[0047] In some embodiments, the ejector 233 is configured to maintain the pressing block 232 at a predetermined position relative to the base 231 .

[0048] The preset position refers to when the push piece 233 pushes the pressing block 232 toward the frame workpiece 102 to a certain position and no longer pushes the pressing block 232, the pressing block 232 stops at this position. In the example, the push piece 233 can have a ratchet, and the base 231 can have a spring pawl matched therewith. In this way, whenever the pawl is engaged with the corresponding ratchet, the position of the push piece 233 relative to the base 231 is fixed, thereby keeping the pressing block 232 at a preset position relative to the base 231, unless an external force is applied, the pressing block 232 will not be able to escape from the preset position. It will be understood that the preset position can be set according to the parameters of the workpiece (for example, the amount of compression to be made of the frame workpiece 102).

[0049] In addition, the ejector 233 may be pushed by a motor or a cylinder so that its position relative to the base 231 remains fixed.

[0050] When the push piece 233 keeps the pressing block 232 at a preset position relative to the base 231, the pressure applied by the pressing block 232 to the frame workpiece 102 remains unchanged, so that in this case, the deformation degree of the frame workpiece 102 can remain relatively constant, which is conducive to more stable welding. This is more advantageous in scenarios where it takes a long time to weld the frame workpiece 102 and the plate workpiece 101.

[0051] In some embodiments, the base 231 may include a threaded through hole 2311, and the push member 233 includes a push rod 2333 having an external thread, the push rod 2333 can rotate in the threaded through hole 2311 to push the pressure block 232 to move, and the cooperation between the external thread of the push rod 2333 and the internal thread of the threaded through hole 2311 enables the push rod 2333 to keep the pressure block 232 in a preset position.

[0052] In the example, the push member 233 can be screwed in a first direction by an external force, so that the push member 233 rotates forward in the threaded through hole 2311, thereby pushing the pressing block 232 connected to the push member 233 to move toward the frame workpiece 102. When the external force is removed, although the push member 233 is no longer screwed, due to the cooperation between the external thread of the screwed push member 233 and the internal thread of the threaded through hole 2311, the push member 233 will be locked in a preset position and will not automatically rotate in a second direction opposite to the first direction.

[0053] Therefore, through the push rod 2333 with external threads and the threaded through hole 2311 with internal threads, not only can the pressing block 232 be pushed to move toward the frame workpiece 102 relative to the base 231, but the pressing block 232 can also be maintained at a preset position relative to the base 231. The structure is simple and easy to operate.

[0054] In some embodiments, continue to refer to Figure 5 The pressing block 232 may include a limiting protrusion 2321, and each side-pushing assembly 230 may also include a limiting block 234 fixed on the base 231. The pressing block 232 and / or the limiting block 234 are configured such that when the pressing block 232 moves toward the frame workpiece 102 until the limiting protrusion 2321 abuts against the limiting block 234, the limiting block 234 prevents the pressing block 232 from continuing to move toward the frame workpiece 102.

[0055] In an example, the size of most areas of the pressing block 232 may be set to just pass through the position between two limiting blocks 234 , and the size of the limiting protrusion 2321 may be set to be unable to pass through the position between the limiting blocks 234 .

[0056] Therefore, by providing the limiting block 234 , it is possible to prevent the pressing block 232 from excessively pressing the frame workpiece 102 and causing the frame workpiece 102 to be excessively deformed.

[0057] In some embodiments, each side thrust assembly 230 may further include an adjustment gasket 235 , which is detachably disposed on a surface of the limiting block 234 for contacting the limiting protrusion 2321 .

[0058] The adjusting pad 235 may be, for example, a magnetic sheet, which may be adsorbed on the limiting block 234 by magnetic force. When not needed, one or more adsorbed adjusting pads 235 may be removed.

[0059] In addition, it will be understood that the adjustment gasket 235 can also be detachably disposed on the surface of the limiting block 234 for contacting the limiting protrusion 2321 in other ways.

[0060] Therefore, the maximum squeezing amount of the side push assembly 230 on the frame workpiece 102 can be adjusted according to different scenes or different specifications of the workpieces 100 to be welded.

[0061] In some embodiments, the pressing block 232 may include a through slot 2322 with a closing end, and the ejector 233 has a head 2331 and a neck 2332 that cooperate with the through slot 2322, wherein the radial dimension of the neck 2332 is smaller than the radial dimension of the head 2331, so that the neck 2332 can move in the closing end, while the head 2331 cannot pass through the closing end.

[0062] The head 2331 of the ejector 233 can be inserted into the through slot 2322 from the upper side or the lower side of the through slot 2322, but cannot be inserted into the through slot 2322 from the side of the closing. After the head 2331 is inserted into the through slot 2322, the neck 2332 cooperates with the closing, and the relatively narrow size of the closing does not allow the head 2331 to pass from the side.

[0063] Therefore, the ejecting member 233 and the pressing block 232 can be assembled and disassembled relatively conveniently, and when the ejecting member 233 is required to push the pressing block 232 , the ejecting member 233 will not be separated from the pressing block 232 .

[0064] In some embodiments, the at least one side push assembly 230 includes a plurality of side push assemblies respectively arranged at a plurality of edges of the tooling body 210 , and for each edge of the tooling body 210 , there is at least one side push assembly 230 arranged at the middle position 211 of the edge.

[0065] like Figure 3 As shown, a side thrust assembly 230 is disposed at the middle position 211 of each of the four sides of the tooling body 210 .

[0066] In addition, if a side of the tooling body 210 is longer, a plurality of side push assemblies 230 may be further arranged along the side.

[0067] Therefore, the side push assembly 230 disposed at the middle position 211 of the edge of the tooling body 210 can push up the middle position 211 of the frame workpiece 102 , thereby achieving a better deformation effect of the frame workpiece 102 .

[0068] In some embodiments, the welding tool 200 may further include a pressing component 240, and the pressing component 240 includes:

[0069] A bracket, the bracket is fixed on the tooling body 210; and a pressing arm, the pressing arm can move between a first position and a second position relative to the bracket. At the first position, the pressing arm presses against the frame workpiece 102 to fix the frame workpiece 102, and at the second position, the pressing arm is disengaged from the frame workpiece 102 to release the frame workpiece 102.

[0070] In an example, the bracket of the pressing assembly 240 may be fixed to the tool body 210 by screws or welding.

[0071] like Figure 3 As shown, the pressing arm of the pressing assembly 240 can be rotated to a position substantially perpendicular to the frame corresponding to the frame workpiece 102, thereby preventing the frame workpiece 102 from moving upward. In addition, the pressing arm of the pressing assembly 240 can be rotated to a position substantially parallel to the frame corresponding to the frame workpiece 102, thereby disengaging the pressing arm from the frame workpiece 102 to release the frame workpiece 102.

[0072] Therefore, when welding is performed, the frame workpiece 102 can be better fixed by pressing the frame workpiece 102 with the pressing arm of the pressing assembly 240 to prevent it from shifting, which is beneficial to improving the welding quality.

[0073] In some embodiments, the welding tool 200 may further include at least one suction cup 250 , which is disposed on the tool body 210 and is used to absorb the plate-like workpiece 101 when the plate-like workpiece 101 is supported on at least one support member 220 .

[0074] In the example, refer to Figure 7 , the suction cup 250 can be connected to the tooling body 210 through the bracket below it. When the suction cup 250 is installed on the tooling body 210, the position of its highest point can be higher than the position of the highest point of the support member 220, so that when the plate-like workpiece 101 is supported on at least one support member 220, the suction cup 250 can be effectively pressed down, so that the suction cup 250 can better absorb the plate-like workpiece 101. It will be understood that the number of suction cups 250 can be multiple, and can be arranged according to actual needs.

[0075] In an example, the suction cup 250 may be connected to a negative pressure passage, thereby sucking the plate-shaped workpiece 101 using negative pressure.

[0076] Therefore, when welding is performed, the plate-like workpiece 101 can be adsorbed by the suction cup 250, so that the plate-like workpiece 101 can be better fixed to prevent it from shifting, which is beneficial to improving the welding quality.

[0077] In some embodiments, Figure 7 As shown, at least one support member 220 may include: a support surface 221 for contacting the plate-like workpiece 101; and a support column 222 for connecting the support surface 221 and the tooling body 210, and the length of the support column 222 is adjustable.

[0078] The support surface 221 may be a flat support surface, and the material of the support surface 221 may be a material softer than metal (such as rubber), thereby providing a buffer for the plate-like workpiece 101 and preventing the plate-like workpiece 101 from being scratched.

[0079] The support column 222 can be in the form of two parts of the support column sleeved together, and the length of the support column 222 can be adjusted by adjusting the length of the two parts sleeved together.

[0080] Therefore, when, for example, it is necessary to weld a plate-like workpiece 101 with a frame workpiece 102 of different thicknesses, the height of the plate-like workpiece 101 supported on the support member 220 can be adjusted by adjusting the length of the support column 222 to align with the frame workpiece 102 of different thicknesses, thereby being able to adapt to different workpieces 100 to be welded.

[0081] An embodiment of the second aspect of the present application provides a welding device, which includes: a welding tool 200, the welding tool 200 is used to carry the workpiece to be welded (such as the plate-shaped workpiece 101 and the frame workpiece 102 mentioned above); and a welding machine, the welding machine is used to weld the workpiece to be welded carried on the welding tool 200.

[0082] Since the welding tool 200 has the side push assembly 230, the frame workpiece 102 can be pushed toward the inside of the frame as a whole, so that the frame workpiece 102 is bent inward. When the frame workpiece 102 is bent inward, the welding machine welds the frame workpiece 102 and the plate-shaped workpiece 101. After the welding process is completed, the side push assembly 230 can no longer push the frame workpiece 102, but allow the frame workpiece 102 to rebound. In this way, the plate-shaped workpiece 101 welded on the frame workpiece 102 can be pulled under the action of the rebound force of the frame workpiece 101, so that the plate-shaped workpiece 101 is more flat.

[0083] The technical solution of the present application is further described below through a specific embodiment.

[0084] refer to Figures 1 to 7The welding tool 200 includes: a tool body 210, at least one supporting member 220, a plurality of side pushing assemblies 230 respectively arranged at a plurality of edges of the tool body 210, a pressing assembly 240, and at least one suction cup 250.

[0085] The support member 220 is disposed on the tool body 210 and is used to support the plate-shaped workpiece 101 to be welded. The support member 220 includes: a support surface 221 for contacting the plate-shaped workpiece 101; and a support column 222 for connecting the support surface 221 and the tool body 210, and the length of the support column 222 is adjustable.

[0086] The side push assembly 230 is arranged on the tooling body 210, and is used to deform the frame workpiece 102 to be welded with the plate-shaped workpiece 101. The side push assembly 230 includes a base 231, a pressure block 232 and a push member 233. The base 231 includes a threaded through hole 2311, and the push member 233 is a push rod 2333 with an external thread, and the push rod 2333 can rotate in the threaded through hole 2311 to push the pressure block 232 to move, and the cooperation between the external thread of the push rod 2333 and the internal thread of the threaded through hole 2311 enables the push rod 2333 to keep the pressure block 232 in a preset position. For each edge of the tooling body 210, there is at least one side push assembly 230 arranged at the middle position of the edge.

[0087] In addition, the pressing block 232 includes a limiting protrusion 2321, and each side push assembly 230 may also include a limiting block 234 fixed on the base 231. The pressing block 232 and / or the limiting block 234 are configured such that when the pressing block 232 moves toward the frame workpiece until the limiting protrusion 2321 abuts against the limiting block 234, the limiting block 234 prevents the pressing block 232 from continuing to move toward the frame workpiece. The pressing block 232 includes a through slot 2322 with a closed opening, and the push member 233 has a head 2331 and a neck 2332 that cooperate with the through slot 2322. The radial dimension of the neck 2332 is smaller than the radial dimension of the head 2331, so that the neck 2332 can move in the closed opening, while the head 2331 cannot pass through the closed opening.

[0088] Each side thrust assembly 230 further includes an adjusting gasket 235 , which is detachably disposed on a surface of the limiting block 234 for contacting the limiting protrusion 2321 .

[0089] The pressing assembly 240 includes: a bracket, the bracket is fixed on the tooling body 210; and a pressing arm, the pressing arm can move between a first position and a second position relative to the bracket. In the first position, the pressing arm presses against the frame workpiece to fix the frame workpiece, and in the second position, the pressing arm is disengaged from the frame workpiece to release the frame workpiece.

[0090] The suction cup 250 is disposed on the tool body 210 , and is used to suck the plate-like workpiece 101 when the plate-like workpiece 101 is supported on at least one support member 220 .
