Description

Technical Field

[0001] The utility model relates to a bearing stringing manipulator and a full-automatic bearing loading and detecting machine. Background Art

[0002] At present, the stringing shaft manipulator is adopted for batch loading of bearings. The stringing shaft of the stringing shaft manipulator strings the multiple columns of bearings stacked in the bearing bin one by one to the transfer platform, and then the transfer platform conveys them to the detection station for groove diameter detection. However, at present, when the stringing shaft moves towards the bearing bin, it will hit the side wall or the bearings of the bearing bin due to inaccurate position, resulting in inaccurate stringing or damage to the stringing shaft. Content of the Utility Model

[0003] To overcome the above disadvantages, the purpose of the utility model is to provide a bearing stringing manipulator and a full-automatic bearing loading and detecting machine that can accurately string the bearings in the bearing bin to the transfer platform.

[0004] To achieve the above purpose, one of the technical solutions adopted by the utility model is: a bearing stringing manipulator, including a stringing shaft and a moving module. The stringing shaft can pass through the centers of the stacked bearings in the bearing bin and is driven by the moving module to be transferred to the next station. A connecting frame is arranged at the free end of the moving module, and a CCD camera is fixed on the connecting frame. A connecting block is arranged at the connecting end of the stringing shaft, and the connecting block is slidably arranged on the connecting frame. The connecting block can slide back and forth in the axial direction of the stringing shaft. A return spring is arranged between the side surface of the connecting block and the connecting frame, and the elastic force of the return spring forces the stringing shaft to move towards the bearing bin direction. A sensor for detecting the movement of the connecting block is arranged on the connecting frame.

[0005] Preferably, a roller is arranged inside the free end of the stringing shaft, and the roller protrudes from the end surface of the free end of the stringing shaft. The roller can slide relative to the outer wall of the bearing bin. The free end of the stringing shaft is protected.

[0006] A full-automatic bearing loading and detecting machine includes a bearing bin, a transfer platform, and a groove diameter detector. The bearing bin and the transfer platform are connected by the above-mentioned bearing stringing manipulator. The bearing stringing manipulator is used to transfer the stacked bearing columns in the bearing bin to the transfer platform. A conveying platform is arranged below one side of the transfer platform, and a pushing component is arranged between the discharging end of the transfer platform and the conveying platform. The bearings on the transfer platform are placed vertically, and the bearings on the conveying platform are placed horizontally. The conveying platform passes through the groove diameter detector.

[0007] Preferably, the transfer platform includes a horizontally arranged supporting platform and baffles located on both sides of the supporting platform. A conveyor belt is arranged on the supporting platform, and the conveyor belt is driven by a motor.

[0008] Preferably, the pusher assembly includes a pusher plate on one side of the discharge end of the support table and a receiving track on the other side. The receiving track can only accommodate the thickness of one bearing. The receiving track is arranged vertically. The upper end of the receiving track corresponds to one side of the discharge end of the support table and is provided with a slot. The lower end of the receiving track is an arc structure guiding towards the transfer platform. The pusher plate can be driven by a pusher cylinder to push the bearing at the discharge end of the support table into the slot and slide from the receiving track to the transfer platform.

[0009] Preferably, the transfer platform includes a power transfer platform and a non-power transfer platform. The starting end of the power transfer platform is connected to the lower end of the receiving track. The end of the power transfer platform is connected to the non-power transfer platform, and the two are connected by a push plate assembly. The groove diameter detector is arranged on the non-power transfer platform.

[0010] Preferably, the push plate assembly includes a horizontal push plate, a driving cylinder, and a Y-axis driving cylinder. A plurality of grooves are arranged on the horizontal push plate, and each groove can only accommodate one bearing. The driving cylinder drives the horizontal push plate to reciprocate between the power transfer platform and the non-power transfer platform. The Y-axis driving cylinder drives the X-axis driving cylinder to move back and forth in the direction away from or close to the power transfer platform and the non-power transfer platform.

[0011] The beneficial effects of the bearing stringing manipulator and the full-automatic bearing feeding and detecting machine of the present utility model are as follows:

[0012] First, a CCD camera is adopted, which can identify the position of the stacked bearing rows in the bearing bin, reducing the possibility of the stringing shaft hitting, and protecting the stringing shaft, the bearing bin, and the bearing rows in the bearing bin.

[0013] Second, even when the stringing shaft hits the bearing bin or the bearings in the bin during stringing, since the stringing shaft is slidably arranged on the connecting frame, it will move backward. Once the sensor monitors that the connecting block at the tail of the stringing shaft moves on the connecting frame, the moving module will adjust the position of the stringing shaft. Combining with the CCD camera, the position of the stringing shaft is finely adjusted. After adjustment, the reset spring forces the originally moved-back stringing shaft to reset, and stringing can continue, ensuring the accuracy of stringing.

[0014] Third, since the stringing shaft can string accurately, the number of bearings transferred to the transfer platform is ensured, and finally the smooth detection of the groove diameter detector is ensured, and the detection efficiency of the groove diameter detector is guaranteed.

[0020] The following combines the drawings to elaborate on the preferred embodiments of the present invention, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0021] First embodiment

[0022] Refer to Figures 1 - 3 As shown, this embodiment discloses a bearing stringing manipulator 100, including a stringing shaft 110 and a moving module 120. The stringing shaft 110 can penetrate the center of the stacked bearings 700 in the bearing trolley 200, and is driven by the moving module 120 to be transferred to the next station. A connecting frame 130 is provided at the free end of the moving module 120, and a CCD camera 140 is fixed on the connecting frame 130. A connecting block 112 is provided at the connecting end of the stringing shaft 110. The connecting block 112 is slidably arranged on the connecting frame 130. Specifically, a sliding connection can be realized through a slide rail structure. The connecting block 112 can slide back and forth in the axial direction of the stringing shaft 110. A return spring 150 is provided between the side surface of the connecting block 112 and the connecting frame 130. The elastic force of the return spring 150 forces the stringing shaft 110 to move towards the bearing trolley 200. A sensor 131 for detecting the movement of the connecting block 112 is provided on the connecting frame 130.

[0023] As Figure 2 shown, a roller 111 is built into the free end of the stringing shaft 110. The roller 111 protrudes from the end face of the free end of the stringing shaft 110, and the roller 111 can slide relative to the outer wall of the bearing trolley 200.

[0024] The working principle of the bearing stringing manipulator 100 is that if the bearing stringing manipulator 100 does not shift in position during stringing, the reset spring 150 always forces the connecting block 112 towards the bearing loading cart 200, and the connecting block 112 will not move axially along the stringing shaft 110. Once the stringing shaft 110 hits the bearing loading cart 200 or the bearings 700 inside the cart, since the stringing shaft 110 is slidably arranged on the connecting frame 130, it will move backward. Once the sensor 131 detects that the connecting block 112 moves on the connecting frame 130, the moving module 120 will adjust the position of the stringing shaft 110. In combination with the CCD camera 140, the position of the stringing shaft 110 is finely adjusted. After adjustment, the reset spring 150 forces the originally moved-back stringing shaft 110 to reset.

[0025] Embodiment 2

[0026] Refer to Figure 4 、 Figure 5 As shown in [references], this embodiment discloses a fully automatic bearing feeding and detecting machine, which includes a bearing loading cart 200, a transfer platform 300, and a groove diameter detector 400. The bearing loading cart 200 and the transfer platform 300 are connected by the bearing stringing manipulator 100 of Embodiment 1. The bearing stringing manipulator 100 is used to transfer the palletized bearing rows in the bearing loading cart 200 to the transfer platform 300. A transfer platform 500 is arranged below one side of the transfer platform 300. A pushing component 600 is arranged between the discharging end of the transfer platform 300 and the transfer platform 500. The bearings 700 on the transfer platform 300 are placed vertically, and the bearings 700 on the transfer platform 500 are placed horizontally. The transfer platform 500 passes through the groove diameter detector 400.

[0027] The transfer platform 300 includes a horizontally arranged support table 310 and baffles 320 located on both sides of the support table 310. A conveyor belt is arranged on the support table 310 and is driven by a motor 330.

[0028] The pushing component 600 includes a pushing plate 610 on one side of the discharging end of the support table 310 and a receiving track 620 on the other side. The receiving track 620 can only accommodate the thickness of one bearing. The receiving track 620 is arranged vertically. The upper end of the receiving track 620 corresponds to one side of the discharging end of the support table 310 and is provided with a slot 621. The lower end of the receiving track 620 is an arc-shaped structure 622 guiding towards the transfer platform 500. The pushing plate 610 is driven by a pushing cylinder 630 to push the bearing at the discharging end of the support table 310 into the slot 621 and slide from the receiving track 620 to the transfer platform 500.

[0029] The transfer platform 500 includes a powered transfer platform 510 and an unpowered transfer platform 520. The starting end of the powered transfer platform 510 is connected to the lower end of the receiving track 620, and the ending end of the powered transfer platform 510 is connected to the unpowered transfer platform 520, and the two are connected by a push plate assembly 530. The groove diameter detector 400 is arranged on the unpowered transfer platform 520.

[0030] The push plate assembly 530 includes a horizontal push plate 531, a driving cylinder 532, and a Y-axis driving cylinder. A plurality of grooves 533 are arranged on the horizontal push plate 531, and each groove 533 can only accommodate one bearing 700. The driving cylinder 532 drives the horizontal push plate 531 to reciprocate between the powered transfer platform 510 and the unpowered transfer platform 520, and the Y-axis driving cylinder drives the X-axis driving cylinder 532 to move back and forth in the direction away from or close to the powered transfer platform 510 and the unpowered transfer platform 520.

[0031] The working principle of the automatic bearing feeding and detecting machine is that the CCD camera 140 monitors the position of the rows of bearings 700 in the bearing trolley 200, selects the uppermost row of bearings, and the stringing shaft 110 of the bearing stringing manipulator 100 strings the uppermost row of bearings stacked in the bearing trolley 200 to the transfer platform 300. The conveyor belt drives the row of bearings to be transferred to the discharging end of the support table 310. The pushing cylinder 630 drives the pushing plate 610 to move, and pushes one bearing 700 standing at the discharging end of the support table 310 to the slot 621 at the upper end of the receiving track 620. The bearing 700 is transferred along the receiving track 620 to the powered transfer platform 510, and the powered transfer platform 510 horizontally transports it to the discharging end. At the same time, the horizontally placed bearing 700 is located in one of the grooves 533 of the horizontal push plate 531, and is driven by the X-axis driving cylinder 532 to move towards the unpowered transfer platform 520. After arriving, the Y-axis driving cylinder drives the horizontal push plate 531 to move away from the powered transfer platform 510 and the unpowered transfer platform 520, and then resets. At the same time, the groove diameter detector 400 detects the bearing 700. After detection, it is transferred to the next working station by the horizontal push plate 531.
