Referring to fig. 4 to 7, fig. 4 to 7 show an assembly and alignment process of the adaptor plate 26 and the top cover 21 according to some embodiments of the present disclosure, a deviation rectifying device 400 is provided, which includes a bracket 40, a power mechanism 50 and a deviation rectifying mechanism 60. The power mechanism 50 is assembled on the support 40, the deviation correcting mechanism 60 includes an adjusting component 61 and a clamping jaw 64 which are both self-symmetrical relative to a central axis, the adjusting component 61 has a fixed end connected with the support 40 and a movable end connected between the fixed end and the power mechanism 50. The movable end is driven by the power mechanism to move back and forth along the central axis, and the clamping jaw is matched and connected with the movable end and moves synchronously along with the movable end to change the opening and closing degree of the clamping jaw.

The term "opening/closing degree" refers to the opening degree of the clamping jaws 64, and when the opening/closing degree is increased, the clamping jaws 64 are gradually opened, and when the opening/closing degree is decreased, the clamping jaws 64 are gradually closed. The adjustment assembly 61 and the clamping jaw 64 are self-symmetrical with respect to the central axis, i.e. the deviation correction mechanism 60 is self-symmetrical with respect to the central axis. Wherein, the clamping jaw changes self degree of opening and shutting when following expansion end synchronous movement, including two kinds of circumstances. In the first case, as the movable end is far away from the bracket 40, the opening and closing degree of the clamping jaws 64 is gradually increased, and when the movable end moves reversely, the opening and closing degree of the clamping jaws 64 is gradually decreased; in the second case, when the movable end is away from the bracket, the opening and closing degree of the clamping jaw 64 gradually becomes smaller, and when the movable end moves in the opposite direction, the opening and closing degree of the clamping jaw 64 gradually becomes larger.

Referring to fig. 4 to 7, a deviation correcting scenario of a deviation correcting device (not limited thereto) is shown, wherein the deviation correcting device 400 is installed on an apparatus main body 500 of a welding apparatus 2000. The top cap 21 is installed on equipment main part 500, and top cap 21 and insulating part 24 form holding tank P, and the axis of mechanism 60 of rectifying and the axis coincidence installation of holding tank P, the sunken cooperation groove F that forms and holding tank P complex in middle part of adaptor piece 26. A tool (e.g., a robot or a human) transfers the interposer 26 to the receiving slot P or a position near the receiving slot P.

When the opening and closing of the clamping jaws are changed as described in the first case, the actuating mechanism 50 drives the movable end of the adjusting assembly 61 to move towards the accommodating groove P (away from the bracket 40), and the opening and closing degree of the clamping jaws 64 is gradually increased. Because the clamping jaw 64 gradually opens, the clamping jaw 64 gradually pushes against the two sides of the concave surface of the matching groove F, so that the central axis of the matching groove F coincides with the central axis of the clamping jaw 64, when the clamping jaw 64 contacts with the bottom of the matching groove F and the stroke of the clamping jaw 64 is in place, the clamping jaw 64 has the maximum opening and closing degree (the maximum opening and closing degree at the moment is adaptive to the size of the bottom of the matching groove F), and the adapter sheet 26 is installed in place. When the opening and closing of the jaws are changed as described in the second case, the actuating mechanism 50 drives the movable end of the adjusting assembly 61 to move toward the receiving slot P (away from the bracket 40), and the opening and closing degree of the jaws 64 gradually decreases. The concave surface opening of cooperation groove F reduces to the concave surface bottom gradually, and the degree of opening and shutting of clamping jaw 64 follows concave surface cross-section size and reduces, and when clamping jaw 64 contacted with the tank bottom of cooperation groove F, the clamping jaw 64 stroke target in place and clamping jaw 64 had minimum degree of opening and shutting (minimum degree of opening and shutting at this moment and the tank bottom size of cooperation groove F suit), and the adaptor piece 26 is installed and is target in place.

After the adapter sheet 26 is installed in place, the central axes of the clamping jaw 64, the matching groove F and the accommodating groove P are overlapped, the adapter sheet 26 and the accommodating groove P are accurately centered without deviation, and the adapter sheet 26 and the top cover 21 are installed in place. After the adapter sheet 26 is installed in place, the adapter sheet 26 and the top cover 21 are welded, then the power mechanism 50 drives the movable end to move back, the clamping jaw 64 is gradually folded and separated from the matching groove F, and the matching groove F cannot be damaged.

Above-mentioned deviation correcting device 400 controls the degree of opening and shutting of clamping jaw 64 through power unit 50 and adjustment assembly 61 to utilize the degree of opening and shutting that clamping jaw 64 changes to impel cooperation groove F and self centering, and then realize cooperation groove F and holding tank P centering, finally realized that the assembly of adaptor piece 26 and top cap 21 targets in place, avoided the condemned problem of electric core that adaptor piece 26 skew caused.

In a use state, the central axis of the deviation correcting mechanism 60 is arranged along the gravity direction.

In some embodiments of the present application, referring to fig. 4 to 7, the adjusting assembly 61 includes two symmetrical adjusting portions, each of the two adjusting portions includes a connecting rod 62 and a moving member 63, one end of the moving member 63 is connected to the bracket and configured to form a fixed end, the other end of the moving member 63 is hinged to one end of the connecting rod 62 to form a rotating fulcrum, and the other end of the connecting rod 62 is hinged to the power mechanism 50 and configured to form a moving end. The movable end is driven by the power mechanism 50 to move back and forth along the central axis, and drives the connecting rods 62 to rotate around the rotating fulcrum relative to the moving part 63, so as to synchronously drive the clamping jaws 64 connected to the two connecting rods 62 to expand or contract relative to the central axis.

The clamping jaw 64 connected to the two connecting rods 62 means that two parts of the clamping jaw 64 defining the opening and closing degree thereof are respectively connected to the two connecting rods 62. The degree of opening and closing of the jaws 64 decreases when the two portions follow the two links 62 toward each other, and the degree of opening and closing of the jaws 64 increases when the two portions follow the two links 62 away from each other.

In the use state, when the movable end is driven by the power mechanism 50 to move along the central axis away from the bracket 40, the connecting rod 62 moves on the central axis and synchronously drives the clamping jaw 64 to gradually move close to the adapter sheet 26. The link 62 rotates relative to the power mechanism 50 and rotates about a rotation fulcrum during the movement. When the angle of the clamping between the connecting rod 62 and the power mechanism 50 toward the shifting element 63 is smaller (as shown in fig. 4 to 5), the clamping jaws 64 coupled to the connecting rod 62 are spread apart from the central axis, i.e., the degree of opening and closing between the clamping jaws 64 is increased. When the angle between the connecting rod 62 and the power mechanism 50 toward the shifting member 63 is increased, the clamping jaws 64 coupled to the connecting rod 62 are closed relative to the central axis, that is, the degree of opening and closing between the clamping jaws 64 is reduced.

Thus, the movable end is driven by the power mechanism 50 to move along the central axis, so that the opening and closing degree of the clamping jaw 64 is changed.

Specifically, in some embodiments, the varying member 63 includes at least two sub-varying rods hinged to each other, and the movable end changes an included angle between at least two adjacent sub-varying rods when moving.

The variable part 63 may include not only at least two sub-variable rods hinged to each other, but also other connecting structural parts, which are not limited herein.

When the movable end moves, the included angle between at least part of the two adjacent sub-variable rods is changed, so that the variable part 63 is integrally extended and contracted in the direction parallel to the central axis. Specifically, when the movable end moves away from the support 40, the movable part 63 is wholly elongated in the direction parallel to the central axis, so that the lifting height of the clamping jaw can be prolonged, the overall size of the small deviation correcting mechanism is facilitated, and the work of other devices such as tools on welding equipment is more convenient.

Of course, in other embodiments, the varying member 63 may have other configurations, for example, the varying member 63 includes only one varying rod hinged to the bracket 40 and hinged to the connecting rod 62, as long as the length of the varying rod and the connecting rod 62 is designed to achieve the above-mentioned function.

Preferably, referring to fig. 4 to 7, the at least two sub-variable bars include a first sub-variable bar 63a and a second sub-variable bar 63b, the first sub-variable bar 63a is hinged between the second sub-variable bar 63b and the connecting rod 62, one end of the second sub-variable bar 63b connected to the bracket is used as a fixed end, and when the movable end moves, the first sub-variable bar 63a is controlled to change an included angle with the second sub-variable bar 63 b.

In the use state, one end of the second sub-moving lever 63b is connected as a fixed end to the bracket 40, and the position thereof is stationary. When the movable end moves away from the bracket 40, the connecting rod 62 pulls the first sub-moving rod 63a to gradually move away from the bracket 40, the included angle between the first sub-moving rod 63a and the second sub-moving rod 63b gradually increases, and at this time, the size of the moving member 63 in the direction parallel to the central axis is elongated and is unfolded relative to the central axis. When the movable end moves away from the bracket 40, the connecting rod 62 pulls the first sub-moving rod 63a to gradually approach the bracket 40, the included angle between the first sub-moving rod 63a and the second sub-moving rod 63b gradually decreases, and at this time, the size of the moving member 63 in the direction parallel to the central axis is shortened and is folded relative to the central axis. In this case, the mover 63 is constructed by the first sub-mover rod 63a and the second sub-mover rod 63b, and thus has a simple structure, smooth movement, and low manufacturing cost.

It should be noted that, in the above embodiment, one end of the fixed end may be fixedly connected to the bracket 40, or may be hinged to the bracket, and is not limited in particular.

In some embodiments, referring to fig. 4-7, each link 62 includes at least two sub-links, all of which are hinged to each other, and a clamping jaw is coupled to one of the sub-links of each link.

In a use state, when the movable end moves, the degree of freedom of the connecting rod 62 is increased, so that the sub-connecting rod matched and connected with the clamping jaw 64 is always in a horizontal state under the matching of the gravity of the clamping jaw 64, the lifting stability of the clamping jaw 64 can be ensured, the clamping jaw 64 is prevented from deflecting, and the clamping jaw 64 is prevented from damaging the butt joint sheet 26.

Specifically, optionally, the at least two sub-connecting rods include a first sub-connecting rod 62a and a second sub-connecting rod 62b, the first sub-connecting rod 62a, the second sub-connecting rod 62b and the changing member 65 are hinged in sequence, one end of the first sub-connecting rod 62a, which is away from the second sub-connecting rod 62b, serves as a movable end, and the clamping jaw 64 is fixedly connected to the two second sub-connecting rods 62 b.

At this time, the first sub-link 62a rotates about the rotation fulcrum relative to the rotating member 63 via the second sub-link 62b, and the first sub-link 62a and the second sub-link 62b rotate relative to each other, so that the second sub-link 62b can be maintained in a substantially horizontal state by the gravity of the clamping jaw 64. Therefore, the connecting rod has simple structure, less freedom and better controllability.

Alternatively, the second sub-connecting rod 62b is integrally connected with the claw portion 64 a. Therefore, the assembling speed of the deviation correcting device can be accelerated.

In some embodiments, referring to fig. 4 to 7, the clamping jaw 64 includes two claw portions 64a, one end of each of the two claw portions 64a is connected to each of the two sub-connecting rods, and the other end of each of the two claw portions 64a extends away from the bracket 40 in a direction parallel to the central axis, and the opening degree is a distance between the two claw portions 64 a. At this time, in actual use, the two claw portions 64a extend in the gravity direction, and the structure is simple, the manufacturing is convenient, and the engagement groove F is not easily collided or damaged.

In a further embodiment, the other end of each claw portion 64a has a flat pushing portion 64b extending toward each other, and a side surface of the flat pushing portion 64b facing away from the holder 40 is a flat surface. In a using state, the flat pushing portion 64b acts on the bottom of the concave surface of the matching groove F, so that the contact area is large, the damage to the adapter sheet 26 can be avoided, and the deformation of the adapter sheet 26, which leads to the infirm welding of the adapter sheet 26 and the top cover 21 (specifically, the pole on the top cover 21), can also be avoided.

In some embodiments of the present application, referring to fig. 8, the power mechanism 50 includes a driving member 51, a sensor 52, and a floating member 53, the driving member 51 is drivingly connected to the movable end via the floating member 53, the floating member 53 has a floating cavity S that is controlled to be compressible along a central axis, and the driving member is disposed in the floating cavity S and generates an electrical signal when the floating cavity S is compressed.

The floating cavity S is compressible along the central axis, namely the space size of the floating cavity S on the central axis is reduced. Taking the central axis as an example, when the floating chamber S is compressed along the central axis, the space of the floating chamber S in the height direction becomes smaller. When the floating chamber S is compressed, the sensor 52 may be pressurized to generate an electrical signal or may be within a sensible range to generate an electrical signal. When the floating chamber S is not compressed, the sensor 52 is not pressurized or in sensing range and does not generate an electrical signal. Understandably, a float assembly 53 connects the drive end and the free end of the drive member 51.

In the use state, when the movable end descends, the opening and closing degree of the clamping jaws 64 is gradually increased, and the matching grooves F of the adapter sheet 26 are gradually centered. When the outer convex surface of the matching groove F is contacted with the groove bottom of the accommodating groove P, the matching groove F of the adapter sheet 26 and the accommodating groove P are completely centered in place, the moving stroke of the movable end is in place, and the floating cavity S cannot stretch out and draw back on the central axis in the descending process. When the tool places the adapter sheet 26 at a position with a large offset, the claw portion 64a may be restricted by the adapter sheet 26 in the middle of the descending stroke and cannot descend continuously, at this time, the movable end cannot descend and the driving end of the driving member 51 still descends, the floating assembly 53 is compressed by the floating cavity S thereof, and the sensor 52 is pressed and generates an electric signal. When the control system detects that the sensor 52 generates an electrical signal, it indicates that the offset degree of the interposer 26 during placement is too large, so that the deviation correction device 400 cannot correct the offset, and a manual correction or a restart tool is required to transfer the interposer 26.

At this moment, when the deviation degree of the adapter sheet 26 is too large, a worker is reminded of intervention processing, the operation reliability of the equipment is guaranteed, and the smooth assembly of the top cover 21 and the adapter sheet 26 can also be guaranteed.

The sensor 52 may be a pressure sensor 52, a gravity sensor 52, or a proximity switch, etc. When the sensor 52 is a pressure sensor 52 or a gravity sensor 52, an electrical signal is generated when pressurized. When the sensor 52 is a proximity switch, an electrical signal is generated when a sensing portion (the sensing portion may be a metal surface or a metal sheet, which is disposed corresponding to the sensor 52 in the central axis direction) in the floating cavity S is located within a sensing range.

Referring to fig. 8, in some embodiments, the floating assembly 53 includes a first member 54 and a second member 55 floatingly coupled along a central axis and defining a floating chamber S, the first member 54 being coupled to the driving member 51, and the second member 55 being coupled to the movable end.

The first member 54 and the second member 55 are floatingly connected along the central axis, which means that the first member 54 and the second member 55 are controlled to move away from or close to each other on the central axis. When the two approach, the floating chamber S is compressed and the sensor 52 is in a pressurized state. When the two are moved away from each other, the floating chamber S returns to the original spatial size and the sensor 52 is in an uncompressed state.

In the use state, when the claw portion 64a is restricted from descending and the movable end is not moved, the second member 55 is not moved, and the driving end of the driving member 51 is still descended, so that the distance between the first member 54 and the second member 55 is gradually reduced, and the compression of the floating cavity S is realized. At this time, the first piece 54 and the second piece 55 are in floating connection to realize the compressibility of the floating cavity S, so that the structure is simple and the manufacture is convenient.

In a further embodiment, referring to fig. 8, the first member 54 includes a first portion 54a and a second portion 54b defining the floating cavity S together with the second member 55, the first portion 54a is fixed to the driving member 51, the second portion 54b is suspended from the first portion 54a and connected to the second member 55, and the second portion 54b and the driving member 51 can be displaced relatively on the central axis.

The second portion 54b is suspended from the first portion 54a, which means that the second portion 54b is supported by the fixing plate under the action of gravity and is not fixedly connected with the fixing plate. In the use state, when the claw portion 64a is restricted from descending while the driving end of the driving member 51 is still descending, the second member 55 is stationary and remains stationary with the second portion 54b and the second member 55, and the first portion 54a follows the descending of the movable end, so that the floating chamber S is compressed. When the driving end of the driver 51 is raised, the claw portion 64a is disengaged from the adapter sheet 26, and the second portion 54b is suspended from the first portion 54a by the gravity of the claw portion 64a, the second member 55, and the second portion 54 b.

At this time, the first part 54a and the second part 54b realize the floating connection between the first part 54 and the second part 55, which not only has a convenient structure, but also can be reset by the gravity of the second part 54b and the connection part thereof, thereby simplifying the control.

Preferably, an end of the second portion 54b facing away from the second member 55 is sleeved on the driving end of the driving member 51, so as to prevent the second portion 54b from separating from the first portion 54 a.

Of course, in other embodiments, the manner of achieving the floating connection of the first piece 54 and the second piece 55 is not limited thereto. For example, the first member 54 and the second member 55 may be connected by a spring.

In some embodiments of the present application, the driving member 51 includes a cylinder, the cylinder is fixedly connected to the bracket 40, and a piston rod of the cylinder is disposed along the central axis and is in transmission connection with the movable end. At the moment, the movable end is driven to move by the air cylinder, so that the linearity is good, the structure is simple, and the cost is low.

The working process is as follows: the cylinder drives one end of the piston rod to descend, the movable end descends, the included angle between the first sub-variable rod 63a and the second sub-variable rod 63b is increased, the first sub-variable rod 63a pulls the second sub-connecting rod 62b to expand outwards, the distance between the two claw parts 64a is increased, and the claw parts 64a penetrate into the matching groove F of the adapter sheet 26 and drive the matching groove F and the accommodating groove P to be gradually centered. The reverse process is not described in detail. When the adaptor sheet 26 is too large to be corrected, the two claw parts 64a are limited by the adaptor sheet 26 and cannot descend to a predetermined stroke, the second part 54b and the piston rod generate relative displacement, the first part 54a gradually approaches the second part 55, the floating cavity S is compressed, and the sensor 52 generates an electric signal.
