[0038] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0039] Example:

[0040] like Figure 1 to Figure 6 As shown, this embodiment relates to a sensor welding contact quality inspection device, including a frame 2, on which a transmission chain 1 and a welding detector 4 are provided, on which a sliding carrier 3 is carried, and the sliding carrier 3 can reciprocate on the frame 2, and the welding detector 4 is installed on the sliding carrier 3;

[0041] The sliding carrier 3 includes a position-limiting rotating end 34 , and the position-limiting rotating end 34 can rotate and lock the horizontal angle of the welding detector 4 .

[0042] At present, when welding sensor contacts, welding materials need to be piled up at the welding points to achieve the connection. The welding quality is usually reflected by two data: the first is the thickness and uniformity of the welding materials at the welding position, and the second is the non-destructive testing results of the welding position.

[0043] The thickness and uniformity of the welding material at the welding position require observations of the multi-directional distribution of the welding material to obtain conclusions. The existing technology achieves the observation of this phenomenon by setting up multiple multi-directional observation devices. Because a single observation device needs to adjust the observation position, positioning errors are prone to occur during the adjustment of the observation position, resulting in the inability to effectively integrate the observation results.

[0044] Using multiple devices for observation requires effective coordination of the relative positions of each device. Although this improves the fault tolerance rate, it will also bring new problems and greatly increase the quality inspection cost, resulting in a significant increase in product costs, thereby reducing the market competitiveness of the product.

[0045] This embodiment mainly describes the observational quality inspection of the weld appearance at the sensor contact point welding position.

[0046] In this embodiment, the welding detector 4 is moved by driving the sliding carrier 3 through the transmission chain 1, so that the welding detector 4 can be reciprocated in the horizontal position, so that the welding detector 4 can observe more directions, and the horizontal angle of the welding detector 4 is adjusted by the limited rotating end 34 on the sliding carrier 3, so that the angle range that the welding detector 4 can be adjusted is expanded to avoid the existence of detection blind spots.

[0047] The present embodiment utilizes the locking ability of the limited rotating end 34 to effectively control the horizontal rotation angle of the welding detector 4, thereby avoiding the problem of angle error when observing the welding position. The welding detector 4 in the present embodiment can observe the thickness and uniformity of the welding material at the welding position by optical observation, and can also detect the welding position by ultrasonic detection. It can also perform non-destructive detection of the welding position by using radiation. The welding detector in the present embodiment can use existing technology to effectively realize the quality detection of the welding position.

[0048] In this embodiment, a plurality of positioners 33 are provided on the side of the limit rotation end 34. The positioners 33 are used to perform an initial correction of the rotation angle of the limit rotation end 34 before starting the detection, so as to avoid the problem of excessive rotation angle error in long-term use.

[0049] The row frame 2 is provided with a slide rail 6, and the sliding carrier 3 is embedded in the slide rail 6 and can slide back and forth along the slide rail 6;

[0050] The transmission chain 1 is located above the slide rail 6 , and the sliding carrier 3 is movably connected to the transmission chain 1 .

[0051] In this embodiment, the slide rail 6 on the carriage 2 can effectively limit the sliding direction of the sliding carrier 3, thereby controlling the sliding direction of the welding detector 4 carried on the sliding carrier 3, so that the detection position and detection range of the welding detector 4 can be controlled, and the transmission chain 1 can provide the driving force for the sliding of the sliding carrier 3.

[0052] The sliding carrier 3 includes a sliding end 31, and the sliding end 31 can reciprocate on the row frame 2. A mounting block 32 is fixedly connected below the sliding end 31. The position-limiting rotating end 34 is installed below the mounting block 32. A bottom carrying end 35 is fixed below the position-limiting rotating end 34.

[0053] The position-limiting rotation end 34 can rotate relative to the mounting and fixing portion and lock the rotation angle.

[0054] In this embodiment, the sliding end 31 reciprocates on the rack 2, driving the mounting block 32 to reciprocate, and the limiting rotating end 34 is installed on the mounting block 32, so that the horizontal rotation of the limiting rotating end 34 and the reciprocating sliding of the sliding end 31 are relatively independent, thereby expanding the detection range of the welding position and obtaining more complete welding position quality data.

[0055] In this embodiment, the bottom mounting end 35 is used to connect the welding detector 4 , and the bottom mounting end 35 can rotate with the limiting rotation end 34 , so as to effectively control the rotation angle of the welding detector 4 .

[0056] The position-limiting rotating end head 34 includes an end housing 341, a rotating inner gear ring 342 is provided in the end housing 341, a driving gear 348 is provided at the center of the rotating inner gear ring 342, a plurality of planetary gears 347 are provided between the rotating inner gear ring 342 and the driving gear 348, and the rotating inner gear ring 342 and the driving gear 348 are meshed through the planetary gears 347;

[0057] The end shell 341 is provided with a plurality of recessed grooves 343, and a pump 344 is provided in the recessed grooves 343. An extraction slot 345 is provided in the end shell 341, and the extraction slot 345 is connected to the pump 344. The outer side surface of the rotating inner gear ring 342 is provided with a plurality of passive pop-up pins 346, and the passive pop-up pins 346 can be embedded in the extraction slot 345.

[0058] In this embodiment, the driving gear 348 and the rotating inner ring gear 342 are meshed through at least three planetary gears 347. When the driving gear 348 rotates, the planetary gears 347 are driven to rotate and rotate circumferentially around the driving gear 348, thereby achieving the purpose of using the planetary gears 347 to drive the rotating inner ring gear 342 to rotate. Since there are diameter differences among the planetary gears 347, the driving gear 348 and the rotating inner ring gear 342, the rotating inner ring gear 342 can rotate at a slower angular velocity. The rotating inner ring gear 342 is fixedly connected to the bottom mounting end 35, so that the bottom mounting end 35 can achieve horizontal angle adjustment of the welding detector 4 at a more stable angular velocity.

[0059] The recessed groove 343 on the end shell 341 can accommodate the pump 344 to prevent the pump 344 from protruding and causing the limited rotating end 34 to occupy too much space, and the pump 344 can effectively provide negative pressure adsorption for the passive pop-up pin 346, so that the passive pop-up pin 346 is inserted into the extraction slot 345 to lock the rotating inner ring 342, thereby ensuring the stability of the angle adjustment. At this time, there will be a problem of impact on the meshing parts of the planetary gear 347, the driving gear 348 and the rotating inner ring 342. The meshing positions of the planetary gear 347, the driving gear 348 and the rotating inner ring 342 in this embodiment are relatively dispersed, resulting in the dispersion of the impact force, which can effectively avoid damage to the meshing position by dispersing the force.

[0060] The extraction slot 345 includes a pressure block 3451, which is embedded in the end shell 341 and protrudes from the end shell 341, and the outer surface of the pressure block 3451 contacts the outer surface of the rotating inner gear ring 342;

[0061] A limiting cavity 3456 is provided in the pressure block 3451 , and the limiting cavity 3456 is aligned with the outer surface of the internal gear of the gripper. A pump connecting hole 3452 is provided in the limiting cavity 3456 , and the pump connecting hole 3452 is connected to the pump machine 344 .

[0062] A buffer plate 3455 is also provided in the limiting cavity 3456, and a plurality of buffer rods 3454 are fixed on the buffer plate 3455. A buffer groove 3453 is provided in the pressure block 3451, and the buffer groove 3453 extends along the axial direction of the limiting cavity 3456. The buffer rod 3454 is inserted into the buffer groove 3453 and can slide in the buffer groove 3453.

[0063] In this embodiment, the pressure block 3451 in the extraction slot 345 can effectively withstand the negative pressure, and adsorb and limit the passive pop-up pin 346 through the limiting cavity 3456, so as to achieve the purpose of locking the rotating inner gear ring 342, and the buffer plate 3455, the buffer rod 3454 and the buffer groove 3453 in the limiting cavity 3456 work together to achieve the purpose of effectively buffering the impact of the passive pop-up pin 346 on the limiting cavity 3456, thereby ensuring that this embodiment can be repeatedly used for a long time. After the buffer plate 3455 is subjected to the impact, the impact force is transmitted to the buffer rod 3454, and the buffer rod 3454 plays a buffering role through the sliding of the buffer rod 3454 in the buffer groove 3453. The buffer groove 3453 can improve the buffering capacity of the buffer rod 3454 by filling the buffer medium.

[0064] The pump is connected to the limiting cavity 3456 through the pump connecting hole 3452, and the force of the pump 344 is used to provide negative pressure inside the limiting cavity 3456. The limiting cavity 3456 is aligned with the passive pop-up pin 346, so that the limiting cavity 3456 can suck out the passive pop-up pin 346 to achieve the purpose of limiting locking.

[0065] The passive pop-up latch 346 includes a receiving groove 3462, which is embedded in the rotating inner gear ring 342. A latch rod 3461 capable of being embedded in the extraction slot 345 is provided in the receiving groove 3462, and the latch rod 3461 and the receiving groove 3462 are fixed by a tension spring 3463.

[0066] In this embodiment, the passive pop-up latch 346 utilizes a receiving groove 3462 embedded in the rotating inner gear ring 342 to provide a receiving space for the latch rod 3461, and utilizes a tension spring 3463 to prevent the latch rod 3461 from slipping out of the receiving groove 3462. At this time, if the latch rod 3461 is subjected to the force of negative pressure adsorption, it can effectively slip out of the receiving groove 3462 and be inserted into the limiting cavity 3456.

[0067] A support foot 5 is provided at the bottom of the row frame 2, and the support foot 5 includes a support rod 51. A seat body stabilizing portion is provided below the support rod 51, and the support rod 51 is inserted into the seat body stabilizing portion;

[0068] A base part is fixed below the base stabilizing part, and a plurality of bolt holes 510 are provided on the base part, and the bolt holes 510 are connected to the ground.

[0069] In this embodiment, the supporting foot 5 can effectively improve the stability of this embodiment. In the prior art, the position of the frame 2 is usually fixed by bolts. However, since the welding detector 4 carried on the frame 2 needs to be moved, the bottom of the frame 2 is always affected by vibration. The vibration may cause fatigue damage to the bolts or other material damage, thereby causing the risk of support instability.

[0070] In this embodiment, a support rod 51 is used to connect the upper overall device, and the seat stabilizing portion is used as an intermediate support, which effectively prevents the vibration of the support rod 51 from being transmitted to the seat base, thereby making the bolt connection on the seat base more stable and increasing the support life. The bolt holes 510 on the seat base can effectively use bolt connections to complete the fixation of the support feet.

[0071] The seat stabilizing portion includes a seat stabilizing outer shell 52, an inner sleeve 53 is provided in the seat stabilizing outer shell 52, the support rod 51 is inserted into the inner sleeve 53, and a sleeve side support 54 is provided between the inner sleeve 53 and the seat stabilizing outer shell 52;

[0072] A plurality of embedded terminals 55 are embedded in the bottom of the seat body stabilizing shell 52, and a plurality of anchor rods 56 are disposed below the embedded terminals 55. The anchor rods 56 are inserted into the base of the seat body.

[0073] The base part of the seat body includes a base shell 58, and a plurality of anchor sleeves 513 are arranged in the base shell 58. The number and position of the anchor rods 56 correspond to the anchor sleeves 513: each anchor rod 56 corresponds to one anchor sleeve 513;

[0074] The end of the anchor rod 56 is provided with an end bending section 511, and there is an angle between the end bending section 511 and the anchor rod 56, and the anchor sleeve 513 is filled with a fixed filling 512;

[0075] The base shell 58 of the seat body is filled with a plurality of elastic balls 59 .

[0076] In this embodiment, the support rod 51 is limited by the inner sleeve 53 in the seat stabilizing shell 52 in the seat stabilizing portion, and the stability of the inner sleeve 53 itself is improved by the sleeve side support 54. When the support rod 51 is affected by vibration, the inner sleeve 53 can effectively support the side of the support rod 51 and prevent the vibration of the support rod 51 from being transmitted downward, thereby preventing the vibration of the support rod 51 from affecting the position of the bolt connection. Through the dispersed connection of several embedded ends 55, the weight above can be dispersed and transmitted downward, thereby avoiding stress concentration.

[0077] In this embodiment, the anchoring sleeve 513 in the base part of the seat body is used to accommodate the anchor rod 56 and anchor the position of the anchor rod 56. The anchor rod 56 is prevented from escaping from the anchoring sleeve 513 by means of a fixed filling 512, thereby improving the stability of the foundation of this embodiment. The end of the anchor rod 56 is provided with an end bending section 511 to further enhance the anchoring effect.

[0078] When the vibration amplitude above is too large or the supporting foot 5 is affected by other external force factors, the supporting foot 5 may be partially deformed, thereby affecting the support stability. In this embodiment, elastic balls 59 are filled in the base shell 58 of the seat body to ensure that the base shell 58 of the seat body has a certain elastic recovery ability, so that the support stability of this embodiment is enhanced. In this embodiment, the elastic balls 59 have their own elastic recovery ability to resist the effects of all-directional forces in this embodiment within a certain range. The range of action is mainly affected by factors such as the filling amount of the elastic balls 59 and the material of the elastic balls 59.

[0079] A connecting shell 57 is provided between the seat base and the seat stabilizing portion, and the connecting shell 57 is used to lengthen the connection distance between the seat stabilizing portion and the seat base, thereby further reducing the mutual influence between the two and maintaining the stability of the entire device.

[0080] The elastic ball 59 comprises an outer spherical shell 591, an inner spherical shell 594 is arranged inside the outer spherical shell 591, an elastic filler 592 is arranged between the outer spherical shell 591 and the inner spherical shell 594, a pressure-bearing sphere 595 is arranged inside the inner spherical shell 594, a plurality of embedded steel balls 593 are arranged between the pressure-bearing sphere 595 and the inner spherical shell 594, and the embedded steel balls 593 are evenly distributed on the outer surface of the pressure-bearing sphere 595;

[0081] An inner cavity 596 is defined in the pressure-bearing sphere 595 .

[0082] In this embodiment, the outer spherical shell 591 in the elastic ball 59 will use the internal elastic filling 592 to play a buffering role when they are squeezed against each other. When the squeezing force is small, the inner spherical shell 594 can effectively resist the squeezing force and restore the shape of the outer spherical shell 591 through the elastic filling 592. When encountering a larger squeezing force, the inner spherical shell 594 can use the embedded steel ball 593 to improve the resistance and help the outer spherical shell 591 to recover after squeezing. When the squeezing force is too large, the inner spherical shell 594 in the elastic ball 59 will force the inner The embedded steel ball 593 compresses the pressure-bearing sphere 595. If the pressure is less than the pressure that the pressure-bearing sphere 595 can withstand, the elastic ball 59 can still be guaranteed to restore its shape. If the supporting foot 5 is subjected to excessive external force impact, there is a certain probability that the pressure will be greater than the pressure that the pressure-bearing sphere 595 can withstand. In this way, the pressure-bearing sphere 595 will be broken, and the elastic ball 59 will collapse on a large scale, thereby ensuring that the filling space of the elastic ball 59 can reserve enough collapse space, and using deformation to avoid the risk of fracture of the corresponding structure, which plays a certain protective role.

It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
