DETAILED DESCRIPTION

[0070] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0071] In the production of photovoltaic modules, a battery string picking mechanism is often used to carry battery strings. The picking end of the battery string picking mechanism includes several parts such as Figures 1 to 3 The suction cup assembly shown. The suction cup assembly includes a sheet metal part 10, on which two assembly holes 11 are provided, and two suction nozzles 12 are respectively installed in the corresponding assembly holes 11 through a first flat washer 13a, a second flat washer 13b, a spring 14 and a joint 15 to be fixed in the sheet metal part 10.

[0072] The assembly of suction cup components is usually done manually, which is very labor-intensive, wastes manpower, and is inefficient. Therefore, it is urgent to develop an automatic assembly machine for suction cup components. In order to achieve automatic assembly of suction cup components, the suction nozzle needs to be fixed, which requires the design of a special fixture for the suction nozzle.

[0073] Therefore, this application proposes a nozzle fixture, see Figures 4 to 7 As shown, the nozzle clamp proposed in this embodiment includes a base 20 and at least one set of clamping components 30 arranged on the base 20; each set of clamping components 30 can be switched between a closed state and an open state to clamp or release a nozzle 12, wherein,

[0074] The clamping assembly 30 includes a fixed seat 31, a movable seat 32 and an elastic member 39. The fixed seat 32 is fixedly mounted on the base 20, and the movable seat 32 can be mounted on the base 20 close to or away from the fixed seat 31.

[0075] The elastic member 39 is disposed between the fixed seat 31 and the movable seat 32 , the first end of the elastic member 39 abuts against the fixed seat 31 , and the second end of the elastic member 39 abuts against the movable seat 32 ;

[0076] Push the movable seat 32 toward the fixed seat 31 so that the clamping assembly 30 switches to a closed state. At this time, the movable seat 32 cooperates with the fixed seat 31 to clamp a suction nozzle 12 placed therebetween and compress the elastic member 39;

[0077] The movable seat 32 is released, and the elastic member 39 drives the movable seat 32 to move away from the fixed seat 31 , so that the clamping assembly 30 is switched to the open state to take or place the suction nozzle 12 .

[0078] The suction nozzle clamp of the present application is provided with at least one set of clamping components 30, which can clamp at least one suction nozzle 12. When assembling a suction cup assembly including two suction nozzles, the clamping components 30 can be set as two sets, so as to clamp and fix the two suction nozzles 12 to be assembled at the same time; the clamping component 30 can clamp the suction nozzle 12 when an external force is applied to the movable seat 32 through the cooperation of the fixed seat 31, the movable seat 32 and the elastic member 39, and the remaining parts of the suction cup assembly can be assembled after clamping. After the assembly is completed, the external force is removed, and the clamping component 30 can automatically open to release the suction nozzle, and the assembled suction cup assembly can be removed from the suction nozzle clamp. The suction nozzle clamp of the present application has a simple overall structure, stable and reliable operation, and low cost.

[0079] As an implementation manner, a positioning groove 33 is provided on at least one of the fixed seat 31 and the movable seat 32 , and the positioning groove 33 is configured to position the suction nozzle 12 when the suction nozzle 12 is placed or clamped.

[0080] Optionally, positioning grooves 33 are correspondingly provided on the fixed seat 31 and the movable seat 32 . After the clamping assembly 30 is closed, the suction nozzle 12 is positioned by the cooperation of the two positioning grooves 33 , and elastic members 39 are symmetrically provided on both sides of each positioning groove 33 .

[0081] By providing the positioning groove 33, the suction nozzle 12 is positioned when being placed or clamped, thereby ensuring the position accuracy of the suction nozzle 12 and ensuring that the suction cup assembly can be assembled smoothly.

[0082] As an implementation manner, two sets of clamping assemblies 30 are arranged on the base 20 at a preset interval, and the two sets of clamping assemblies 30 are configured to clamp or release two suction nozzles 12 at the same time.

[0083] By arranging two sets of clamping assemblies 30 at preset intervals, the two suction nozzles 12 to be assembled can be clamped and fixed at the same time, so that the two suction nozzles of the suction cup assembly can be assembled at the same time, thereby improving the assembly efficiency of the suction cup assembly.

[0084] As an implementation mode, the movable seats 32 of the two sets of clamping assemblies 30 are connected as a whole through a connecting piece 34 , and a driving part 35 is provided on the connecting piece 34 . The driving part 35 is pushed to drive the two movable seats 32 to synchronously approach the corresponding fixed seats 31 through the connecting piece 34 .

[0085] The movable seats 32 of the two sets of clamping assemblies 30 are connected as a whole through the connecting piece 34, so that the two sets of clamping assemblies 30 are driven by a driving part 35 to clamp or release the two suction nozzles 12 at the same time, which simplifies the overall structure of the suction nozzle clamp and reduces the cost.

[0086] As an implementation mode, the driving part 35 includes a connecting seat 350 and a rolling member 351 . The connecting seat 350 is fixedly mounted on the connecting member 34 . A longitudinal rotating shaft 352 is fixedly mounted on the connecting seat 350 . The rolling member 351 is rotatably mounted on the longitudinal rotating shaft 352 .

[0087] By fixing the connecting seat 350 on the connecting member 34, the rolling member 351 is installed on the connecting seat 350 through the longitudinal rotating shaft 352. When the rolling member 351 is pushed by an external mechanism, the rolling member 351 can roll in contact with the external mechanism, thereby reducing the friction between the driving part 35 and the external mechanism.

[0088] See also Figures 5 to 7 As shown, as an embodiment, the elastic member 39 is a spring, which is horizontally arranged and extends along the moving direction of the movable seat 32. A first accommodating groove 310 is arranged on the side of the fixed seat 31 opposite to the movable seat 32, and a second accommodating groove 320 is arranged on the side of the movable seat 32 opposite to the fixed seat 31. The first accommodating groove 310 is directly opposite to the second accommodating groove 320, and the first end of the spring is inserted into and abuts against the first accommodating groove 310, and the second end of the spring is inserted into and abuts against the second accommodating groove 320.

[0089] By setting the elastic member 39 and cooperating with the first accommodating groove 310 and the second accommodating groove 320, the elastic member 39 provides the movable seat 32 with a rebound force along the horizontal moving direction, providing an elastic member with a simple structure, low cost and easy installation.

[0090] As an embodiment, the clamping assembly 30 also includes a slider 36, a slide rail 37 and a limit plate 38. The slide rail 37 is installed on the base 20 and is located on one side of the fixed seat 31. The movable seat 32 is slidably installed on the slide rail 37 through the slider 36. The movable seat 32 slides along the slide rail 37 to approach or move away from the fixed seat 31; the elastic member 39 is configured to be elastically deformable along the length direction of the slide rail 37; the limit plate 38 is fixedly installed on the base 20 and is located at one end of the slide rail 37 away from the fixed seat 31. The limit plate 38 is used to abut against the slider 36 when the clamping assembly 30 is switched to the open state.

[0091] Through the cooperation of the slider 36 and the slide rail 37, the movement of the movable seat 32 can be guided, thereby improving the stability of the movement of the movable seat 32. By setting the limit plate 38, the slider 36 is prevented from sliding off the slide rail 37 after the elastic member 39 rebounds, thereby limiting the travel of the movable seat 32.

[0092] The nozzle fixture proposed in this embodiment has the following advantages compared with the prior art:

[0093] 1) The overall structure is simple, the operation is stable and reliable, and the cost is low;

[0094] 2) The suction nozzle can be accurately fixed, which is conducive to ensuring the assembly accuracy of the suction cup assembly;

[0095] 3) Two sets of clamping assemblies are provided to achieve simultaneous clamping, fixing or loosening of two suction nozzles, so as to facilitate simultaneous assembly of two suction nozzles of the suction cup assembly and improve the assembly efficiency of the suction cup assembly;

[0096] 4) One driving unit drives two sets of clamping assemblies to clamp or release two suction nozzles at the same time, which simplifies the overall structure of the suction nozzle clamp and reduces costs; at the same time, the driving unit and the external mechanism are in rolling contact, which reduces the friction between the driving unit and the external mechanism.

[0097] Second, see Figure 8 and Fig. 9 As shown, this embodiment also proposes a fixture circulation mechanism, which includes a rotation drive mechanism 50, a rotating platform 60 and a fixture control mechanism 70, wherein: a plurality of processing stations are arranged at intervals on the rotating path of the rotating platform 60, and the processing stations are a loading station 61, at least one assembly station and a unloading station 62 in the rotating direction, and the above-mentioned suction nozzle fixtures 40 are installed at intervals along the circumferential direction on the rotating platform 60, the number of which is the same as the number of the processing stations;

[0099] The fixture control mechanism 70 is fixed relative to the rotating platform 60. The fixture control mechanism 70 is configured to control the nozzle fixture 40 that rotates to the loading station 61 and the unloading station 62 to open or close. The fixture control mechanism 70 is also configured to control the nozzle fixture 40 to always remain in a closed state during the rotation between the remaining processing stations.

[0100] The fixture circulation mechanism of the present application can realize the circulation of the nozzle fixture 40 between different processing stations through the cooperation of the rotary drive mechanism 50, the rotary platform 60 and the fixture control mechanism 70. The rotary circulation method can save space and realize the automatic recycling of the nozzle fixture 40. After the nozzle is clamped by the nozzle fixture at the loading station, it can always be in a clamped state during the subsequent assembly process until the assembly is completed and it flows into the unloading station where it can be taken away, which can ensure that the assembly work can proceed smoothly and improve efficiency.

[0102] Optionally, the circumferential side of the first circular arc plate 71 abuts against the rolling member 351 of the nozzle fixture 40 at the assembly station.
