[0032] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show preferred embodiments of the present invention.

[0033] like Figures 1 to 6 As shown, a valve core precision assembly device 10 with position detection includes a machine platform 100, a material carrier assembly 200 and an assembly assembly 300. The material carrier assembly 200 includes a material carrier seat 210 and a torque screwdriver 220. The torque screwdriver 220 is arranged on the machine platform 100. The material carrier seat 210 is rotatably arranged on the machine platform 100, and the material carrier seat 210 is connected to the output shaft of the torque screwdriver 220. The material carrier seat 210 is provided with a material carrier slot 211 for supporting the valve core 21. The assembly assembly 300 includes a lifting drive member 310, a lifting plate 320, a rotating drive member 330, a sleeve seat 340 and a rotating head 350. The lifting drive member 310 is arranged on the machine platform 100. The lifting plate 320 is slidably arranged on the machine 100 along the vertical direction, and the output shaft of the lifting drive member 310 is connected to the lifting plate 320, the rotating drive member 330 is arranged on the lifting plate 320, the sleeve 340 is slidably arranged on the lifting plate 320 along the vertical direction, the rotating head 350 is arranged on the output shaft of the rotating drive member 330, and the rotating head 350 is penetrated by the sleeve 340, the lifting drive member 310 is used to drive the lifting plate 320 to descend, so that the sleeve 340 is sleeved on the valve cover 23, and then the rotating head 350 is clamped with the valve cover 23, and the rotating drive member 330 is used to drive the valve cover 23 to rotate so as to be screwed with the valve core 21.

[0034] It should be noted that the material loading component 200 and the assembly component 300 are both installed on the machine 100, wherein the material loading component 200 is used to support and fix the valve core 21, and the assembly component 300 is used to screw and fix the valve cover 23 together with the valve spring 22 on the valve core 21. Specifically, the torque screwdriver 220 is installed on the machine 100, the material loading seat 210 is rotatably installed on the machine 100, and the material loading seat 210 is fixedly connected to the output shaft of the torque screwdriver 220. The material loading seat 210 is located above the torque screwdriver 220. A material loading groove 211 is provided on the material loading seat 210, so that the valve core 21 can be adaptively installed in the material loading groove 211. In this way, after the valve core 21 is placed and fixed in the material loading groove 211, the valve spring 22 and the valve cover 23 are placed on the valve core 21 in turn, and then the valve cover 23 is locked and fixed on the valve core 21 by the assembly component 300. Specifically, the lifting plate 320 is mounted on the machine 100 in a sliding manner along the vertical direction, and the lifting plate 320 is driven by the lifting drive 310 to perform lifting motion. The rotating drive 330 is mounted on the lifting plate 320, the sleeve 340 is mounted on the lifting plate 320 in a sliding manner along the vertical direction, the rotating head 350 is mounted on the output shaft of the rotating drive 330, and the rotating head 350 passes through the sleeve 340, so that the rotating head 350 can rotate and slide axially relative to the sleeve 340. In this way, while the rotating drive 330 drives the rotating head 350 to rotate relative to the sleeve 340, the lifting drive 310 drives the lifting plate 320 to descend, that is, the rotating drive 330, the sleeve 340, and the rotating head 350 are integrally lowered. When the sleeve 340 is sleeved on the outer side of the valve cover 23, the sleeve 340 pushes the valve cover 23 and compresses the valve spring 22, so as to correct and position the valve cover 23. When the sleeve 340 continues to descend until it can no longer descend, the rotating head 350 rotates and slides axially relative to the sleeve 340. When the rotating head 350 descends and clamps the valve cover 23, under the action of the rotating drive member 330, the valve cover 23 presses the valve spring 22 and is screwed and fixed on the valve core 21. In this way, automatic assembly is achieved, which can effectively improve the assembly efficiency. It should be noted that since the loading seat 210 is connected to the output shaft of the torque batch 220, when the valve cover 23 is screwed to the limit position relative to the valve core 21, the output shaft of the torque batch 220 will be driven to rotate synchronously. Therefore, by adjusting the torque of the torque batch 220 rotating synchronously, the tightening force between the valve cover 23 and the valve core 21 can be adjusted, thereby ensuring that the assembly quality of each position regulating valve accessory remains consistent. In one embodiment, the lifting drive member 310 is a cylinder, and the rotating drive member 330 is a motor.

[0035] like Figure 1As shown, in one embodiment, the machine 100 includes a base plate 110 and a support plate 120, the support plate 120 is disposed on the base plate 110, the lifting drive member 310 is disposed on the support plate 120, and the lifting plate 320 is slidably disposed on the support plate 120 along a vertical direction.

[0036] Specifically, the support plate 120 is mounted on the bottom plate 110 along the vertical direction, for example, the support plate 120 and the bottom plate 110 are fixed by screws. The lifting drive member 310 is mounted on the support plate 120, and the lifting plate 320 is slidably mounted on the support plate 120 along the vertical direction, for example, a slide rail is mounted on the support plate 120, and the lifting plate 320 is mounted on the slide rail.

[0037] like Figure 1 As shown, in one embodiment, a displacement sensor 361 is provided on one side wall of the support plate 120 , and a baffle 362 is provided on the lifting plate 320 . When the lifting plate 320 is lifted or lowered, the baffle 362 is moved away from or close to the detection end of the displacement sensor 361 .

[0038] Specifically, when the lifting plate 320 descends so that the rotating head 350 screws the valve cover 23 onto the valve core 21, the baffle 362 will push the detection end of the displacement sensor 361. In this way, through the displacement detection value of the displacement sensor 361, it can be known whether the valve cover 23 and the valve core 21 are screwed into place. When they are not screwed into place, an alarm signal can be issued.

[0039] like Figure 3 As shown, in one embodiment, the assembly component 300 also includes two guide columns 371 and two return springs 372. The two guide columns 371 are respectively inserted through the axial sides of the sleeve 340, and the two guide columns 371 are both screwed to the lifting plate 320. The two return springs 372 are respectively sleeved on the two guide columns 371, and one end of the two return springs 372 abuts against the lifting plate 320, and the other ends of the two return springs 372 abut against the sleeve 340.

[0040] Specifically, in order to enable the sleeve 340 to slide relative to the lifting plate 320 in the vertical direction, two guide posts 371 are provided, which respectively pass through the sleeve 340 and are then screwed and fixed to the lifting plate 320. A return spring 372 is mounted on each guide post 371, and the return spring 372 is used to abut the sleeve 340 and the lifting plate 320 respectively. In this way, when the sleeve 340 is abutted by the valve cover 23, the sleeve 340 can slide relative to the lifting plate 320 to compress the return spring 372.

[0041] like Figure 3 As shown, in one embodiment, one end of the two guide pillars 371 away from the lifting plate 320 is respectively screwed with an adjusting screw 373 , and the adjusting screw 373 passes through and is clamped in the sleeve seat 340 .

[0042] In this way, by rotating the adjusting screw 373, the compression of the sleeve 340 push-pull reset spring 372 can be adjusted, that is, the distance difference between the sleeve 340 and the rotating head 350 can be adjusted, so that the sleeve 340 can better press the valve cover 23, and then the valve cover 23 can be rotated by the rotating head 350.

[0043] like Figure 1 As shown, in one embodiment, the assembly component 300 further includes a material discharge sensor 363 . The material discharge sensor 363 is disposed on the support plate 120 , and the material discharge sensor 363 is disposed toward the material carrier 210 .

[0044] Specifically, in order to ensure that the mechanism is activated only after the valve core 21, the valve spring 22, and the valve cover 23 are placed on the material carrier 210 in sequence, a material discharge sensor 363 is provided. The material discharge sensor 363 includes a first sensor and a second sensor, the first sensor is aligned with the height position of the valve core 21, and the second sensor is aligned with the height position of the valve cover 23. It should be noted that due to the elastic effect of the valve spring 22, the valve cover 23 will be higher than the position of the valve core 21, so it is only necessary to detect whether the valve core 21 and the valve cover 23 are discharged to determine whether the valve spring 22 is discharged.

[0045] like Figure 5 and Figure 6 As shown, in one embodiment, the material carrier assembly 200 further includes a replacement seat 230 , which is detachably disposed on the bottom plate 110 , the torque screw 220 is disposed in the replacement seat 230 , and the material carrier 210 is rotatably disposed in the replacement seat 230 .

[0046] It should be noted that, since the shapes of valve cores 21 of different models are different, in order to enable the valve core precision assembly equipment 10 with position detection of the present application to be suitable for assembling valve cores 21 of different models, a replacement seat 230 is provided. Specifically, the replacement seat 230 is detachably mounted on the base plate 110, and the carrier seat 210 is rotatably mounted in the replacement seat 230 through a bearing, so that the carrier seat 210 can rotate relative to the replacement seat 230. Furthermore, the torque screwdriver 220 is also fixedly mounted in the replacement seat 230, and the output shaft of the torque screwdriver 220 is fixedly connected to the carrier seat 210. In one embodiment, the torque screwdriver 220 is fixedly mounted on the replacement seat 230 by a machine screw.

[0047] like Figure 6 As shown, in one embodiment, a Hall sensor 241 is disposed on the replacement seat 230 , and a magnet 242 is disposed on the outer wall of the material carrier 210 . When the material carrier 210 rotates, the magnet 242 passes through the Hall sensor 241 .

[0048] Specifically, since the carrier seat 210 is connected to the output shaft of the torque batch 220, the torque batch 220 and the displacement seat 230 are fixedly installed, the output shaft of the torque batch 220 has a predetermined torque resistance, and the carrier seat 210 is used to fix the valve core 21. When the rotating head 350 drives the valve cover 23 and the valve core 21 to rotate and screw together, and the valve cover 23 and the valve core 21 are screwed into place, the rotating head 350 will drive the valve core 21 to rotate synchronously, thereby applying torque to the carrier seat 210. When this torque is greater than the predetermined torque resistance of the torque batch 220, the carrier seat 210 will rotate together with the output shaft of the torque batch 220 relative to the torque batch 220. At this time, it means that the valve cover 23 and the valve core 21 are assembled. In order to better feedback the signal of assembly completion, a structure using the Hall sensor 241 to sense the magnet 242 to generate an induction signal is provided. Specifically, the Hall sensor 241 is used to be electrically connected to the controller (the controller can be a PLC controller). When the carrier 210 drives the magnet 242 to pass through the Hall sensor 241 twice, that is, the Hall sensor 241 detects two sensing signals, which means that the valve cover 23 and the valve core 21 are screwed into place. At this time, the controller can determine whether the valve cover 23 and the valve core 21 are assembled in place through the displacement signal fed back by the displacement sensor 361. When the valve cover 23 and the valve core 21 are not assembled in place and tilt, the Hall sensor 241 detects two sensing signals, but because there is no detection signal from the displacement sensor 361, the controller can issue a warning of unqualified assembly. In this way, only when the Hall sensor 241 sends two sensing signals to the controller and the displacement sensor 361 also sends a displacement signal to the controller, the controller determines that the valve cover 23 and the valve core 21 are assembled properly, so that the assembly quality of the thermostatic valve accessories can be improved.

[0049] like Figure 2 and Figure 6 As shown, in one embodiment, a fixing seat 130 is disposed on the lower side of the base plate 110 , a locking piece 140 is disposed on one side of the fixing seat 130 , and the replacement seat 230 is penetrated from top to bottom in the fixing seat 130 , and the locking piece 140 is used to clamp the replacement seat 230 .

[0050] It should be noted that the fixing seat 130 is fixed on the lower side of the bottom plate 110 by screw locking, wherein a through hole penetrating the structure is provided in the fixing seat 130. The locking member 140 is installed on a side wall of the fixing seat 130. When the replacement seat 230, the material carrier seat 210, and the torque screw 220 are inserted into the fixing seat 130 as a whole, the replacement seat 230 is clamped by the locking member 140. In this way, the replacement seat 230 can be detachably installed relative to the bottom plate 110.

[0051] like Figure 6As shown, in one embodiment, the locking member 140 includes a locking seat 141, a locking pin 142 and a locking spring 143. The locking seat 141 is screwed on one side of the fixing seat 130, the locking pin 142 is passed through the locking seat 141, and the locking spring 143 is respectively abutted against the locking pin 142 and the locking seat 141. The locking spring 143 is used to push the locking pin 142 to pass through the replacement seat 230.

[0052] Specifically, the outer wall of the locking seat 141 is provided with an external thread, and the radial direction of the fixing seat 130 is provided with an internal thread adapted to the external thread, so that the locking seat 141 can be screwed and installed on one side of the fixing seat 130. The locking pin 142 passes through the locking seat 141, and the locking spring 143 is sleeved on the locking pin 142, and the locking spring 143 is respectively in contact with the locking pin 142 and the locking seat 141. The elastic thrust of the locking spring 143 makes the locking pin 142 have a tendency to be inserted into the axis of the fixing seat 130. In this way, a clamping groove is provided on the side wall of the replacement seat 230, and one end of the locking pin 142 passes through the clamping groove of the replacement seat 230, so that the replacement seat 230 can be clamped on the fixing seat 130. When the replacement seat 230 needs to be removed, a pulling force in the opposite direction is applied to the locking pin 142, so that the end of the locking pin 142 exits the clamping groove of the replacement seat 230.

[0053] like Figure 6 As shown, in one embodiment, the material carrier assembly 200 further includes an adapter 240 , and the adapter 240 is connected to the output shaft of the torque screwdriver 220 and the bottom end of the material carrier 210 respectively.

[0054] Specifically, since the connection structure of the output shaft of the torque screwdriver 220 and the material carrier 210 is different, an adapter 240 is provided as a middle connection structure between the two. In one embodiment, one end of the adapter 240 is a four-sided column structure, and the other end of the adapter 240 is a six-sided column structure.

[0055] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
