Description

Technical Field

The utility model relates to the technical field of photovoltaic modules, in particular to automatic installation equipment of an IV power-on test fixture.

Background

The photovoltaic IV curve test is an important basis for analyzing the power generation performance of the photovoltaic module. IV curve testing is required before the photovoltaic module leaves the factory to determine whether the electrical performance of the photovoltaic module is normal or not and the power level. The photovoltaic module needs to be connected with test equipment through an IV electrification test tool in the IV test process, elastic clamping connectors at two ends of the IV electrification test tool are fixed on the frame of the photovoltaic module, the connector lug of the junction box of the photovoltaic module is inserted into a socket of the IV electrification test tool, and an anode copper block and a cathode copper block in the IV electrification test tool are connected with an IV test instrument to carry out IV curve and EL test.

Six-axis robots are adopted in the existing photovoltaic module production line to automatically install the IV power-on test fixture into the photovoltaic module, and the specific installation flow is as follows: the middle part of the six-axis robot grabbing tool is transferred to the upper part of the photovoltaic module; the six-axis robot slightly tilts the tool, so that a clamping joint at one end of the tool is contacted with a frame at one side of the photovoltaic module, and thrust is applied to compress a spring at the side of the tool so as to shorten the whole tool; the six-axis robot aligns the tool and withdraws the thrust, and the spring resets to enable the clamping connector on the other side of the tool to be clamped on the frame on the other side of the photovoltaic module; the six-axis robot sequentially grabs positive and negative electrode connector lugs of the photovoltaic module junction box and inserts the positive and negative electrode connector lugs into positive and negative electrode sockets of the IV power-on testing tool, and automatic installation of the IV power-on testing tool is completed. The whole set of installation equipment comprises six robots and a photovoltaic module conveying mechanism, the six robots are arranged on the side edges of the photovoltaic module conveying mechanism, the number of the six robots is one (clamping and placing of a tool is required to be executed, clamping and placing of positive and negative wiring heads are required to be executed in sequence), or two (clamping and placing of the tool is required to be executed, clamping and placing of one of the positive and negative wiring heads are executed at the same time, and clamping and wiring of the other one of the positive and negative wiring heads are required to be executed.

The automatic installation method of the IV power-on test tool has the following defects: 1. the six-axis robot clamps the middle part of the IV power-on test tool and the action of obliquely applying thrust to mount the IV power-on test tool possibly causes deformation of the IV power-on test tool, so that the service life of the IV power-on test tool is shortened; 2. the six-axis robot must firstly put the IV power-on testing tool in the photovoltaic module, then pick up the connector lug, and the IV power-on testing tool which is firstly put can be pressed above the connector lug because the position of the connector lug on the photovoltaic module is random, so that the six-axis robot can possibly catch the connector lug; 3. the six-axis robot is used for grabbing the IV power-on test fixture, placing the IV power-on test fixture and plugging wires, the work flows are needed to be carried out sequentially, and the applicant finds that the installation time of the method is more than 16s through testing, the speed is slower, and the productivity of the photovoltaic module production line is limited; 4. the six-axis robot has higher cost, larger size, high equipment manufacturing cost and large occupied production line space; after the IV power-on test tool is repeatedly used for many times, the abrasion of the tool is large by adopting the method, the tool can droop due to dead weight when being installed in a photovoltaic module, the distance between the IV power-on test tool and the position of the connector lug is increased, and the connector lug has the risk that the connector lug cannot be accurately inserted into a socket of the IV power-on test tool.

Therefore, it is necessary to provide a new automatic installation device for IV power-on test fixture to solve the above-mentioned problems.

Specifically, the front end and the rear end of the conveying mechanism 20 extend out of the material inlet 11 and the material outlet 12 respectively, and are used for conveying the photovoltaic module 90 from the material inlet 11 to the material outlet 12. Specifically, the conveying mechanism 20 conveys the photovoltaic module 90 into the casing 10 through the feeding hole 11 and positions the photovoltaic module in the casing 10 so as to be convenient for assembling and connecting with the IV power-on testing tool 80 later, and conveys the photovoltaic module 90 out of the casing 10 through the discharging hole 12 after being installed and connected with the IV power-on testing tool 80 for subsequent testing. That is, the automatic installation apparatus in the embodiment of the present utility model only completes the installation of the IV power-on test fixture 80 and the photovoltaic module 90 in the casing 10. The feeding mechanism 60 is disposed at the opening of the casing 10. Specifically, as shown in fig. 2, a customer may set a tool conveying line 70 for conveying and feeding IV power-on test tools 80 to be installed from the back to the front along the first direction, that is, in the direction indicated by the arrow in fig. 2, on the outside of the opening of the casing 10, where the tool conveying line 70 belongs to the customer's own setting according to actual production, and the specific structure is not described and limited, and is not a part of the automatic installation apparatus in the embodiment of the present utility model. The feeding mechanism 60 is used for transferring the IV power-on test tool 80 conveyed on the tool conveying line 70 to the intermediate line 50 in the casing 10.

The picking and placing mechanism 40 is disposed in the casing 10 and above the conveying mechanism 20, and the picking and placing mechanism 40 is movable along the second direction.

In the embodiment of the utility model, the clamping joints at two ends of the photovoltaic module 90, namely the first clamping joint 831 and the second clamping joint 832 are synchronously contracted inwards when the picking and placing mechanism 40 is used for picking at the loading position, so that the picking and placing mechanism only needs to be horizontally placed downwards for releasing when the picking and placing mechanism is subsequently installed in the photovoltaic module 90, one end of the tool is not required to be inclined and the stress end is easier to deform when the pushing force is applied as in a six-axis robot in the prior art, and the service life of the tool is shortened. According to the automatic installation equipment provided by the embodiment of the utility model, when the tool is clamped by the picking and placing mechanism 40, the two ends are uniformly stressed, and the deformation is not easy to generate.

Meanwhile, the automatic installation equipment in the embodiment of the utility model installs the tooling after the wire is inserted, so that the problem that the connector lug on the photovoltaic module 90 cannot be caught due to the fact that the connector lug is pressed by the tooling is avoided, namely the automatic installation equipment in the embodiment of the utility model is free from shielding interference, and the connector lug is taken smoothly and accurately. In addition, in the embodiment of the utility model, the connector lug is firstly inserted into the tool and then is mounted on the photovoltaic module 90, so that the insertion of the connector lug cannot be influenced by the abrasion of the tool, and the connector lug cannot be inserted into the socket.

As shown in fig. 3, the conveying mechanism 20 includes a belt line 21 and a return mechanism. Let the feed inlet 11 side be the front side and the discharge outlet 12 side be the rear side.

The blocking mechanism 23 is fixed to a side of the belt line 21, the forward pushing mechanism 22 is movably disposed in the middle of the belt line 21 in the first direction, that is, in the front-rear direction, and the two third side pushing mechanisms 24 are relatively movably disposed on both sides of the belt line 21 in the second direction. In the embodiment of the present utility model, the four belt lines 21 are exemplified, and the four belt lines 21 are connected with a driving motor (not labeled) on one side of the belt lines through a driving wheel (not labeled) and a connecting rod (not labeled) on the rear side to realize synchronous transmission. The two blocking mechanisms 23 are respectively arranged at the inner sides of the rear ends of the two belt lines 21 at the two sides, the two third side pushing mechanisms 24 are respectively arranged at the outer sides of the two belt lines 21 at the two sides, the front pushing mechanism 22 is arranged at the middle of the front ends of the two belt lines 21 in the middle, and the front pushing mechanism 22 can push the photovoltaic module 90 from front to back along the first direction. The blocking mechanism 23 is used for blocking and positioning the rear end of the photovoltaic module 90, the forward pushing mechanism 22 is used for moving backwards to be abutted to the front end of the photovoltaic module 90 so as to block and position the front end of the photovoltaic module 90, and the two third side pushing mechanisms 24 are used for blocking and positioning two sides of the photovoltaic module 90 respectively. In the embodiment of the present utility model, the blocking mechanism 23 is fixed on the horizontal plane, that is, the first direction and the second direction are not movable and can be lifted in the vertical direction, and the third side pushing mechanism 24 is movable in the second direction but is not movable in the first direction and the vertical direction, and the front pushing mechanism 22 is movable in the first direction and can be lifted in the vertical direction but is not movable in the second direction. Preferably, the forward pushing mechanism 22, the blocking mechanism 23 and the third side pushing mechanism 24 are all driven by means of air cylinders, and the specific structure is not described and limited. The cylinder driving structure is simple and the cost is low. It should be noted that, the forward pushing mechanism 22, the blocking mechanism 23, and the third side pushing mechanism 24 are respectively provided with a positioning roller 25 for abutting against a corresponding side edge of the photovoltaic module 90 to position the photovoltaic module 90. In the embodiment of the present utility model, preferably, in order to facilitate the subsequent delivery of the photovoltaic module 90 out of the housing, the photovoltaic module 90 is positioned on the delivery mechanism 20 to be biased to the discharge port 12 side, that is, the positioning of the photovoltaic module 90 is positioned at a rear position. The number of positioning rollers on each blocking mechanism 23 is preferably one, the number of positioning rollers on the forward pushing mechanism 22 is two and symmetrically arranged, and the number of positioning rollers 25 on each third side pushing mechanism 24 is also two and symmetrically arranged. In addition, the positioning roller 25 on the forward pushing mechanism 22 and the positioning roller 25 on the blocking mechanism 23 are lifting rollers capable of lifting along the vertical direction, such as lifting by means of cylinder driving, and the lifting mechanism is simple in structure and low in cost, and is designed to avoid blocking interference of the photovoltaic module 90 when the photovoltaic module 90 enters the positioning position and is conveyed out of the casing 10 from the positioning position, and the positioning rollers 25 on the two third side pushing mechanisms 24 are not interfered with the conveying direction of the photovoltaic module 90, so that lifting is not required.

As shown in fig. 4, the feeding mechanism 60 includes a bracket 61, a first linear motion module 62, and a feeding assembly 63. The support 61 comprises a horizontally arranged horizontal frame connected to a frame body (not shown) in the casing 10 and two diagonal plates, and two parallel first linear motion modules 62 are disposed on the horizontal frame and extend along a second direction, i.e., a Y direction in the drawing, and for the first linear motion modules 62, for example, a module including a rack and pinion and a linear guide, or a module including a synchronous belt and a linear guide, or other modules known to those skilled in the art, the linear guide is described as a first linear guide for convenience of distinction. The feeding assembly 63 is slidably connected to the two first linear motion modules 62, which are not specifically described and limited. The specific structure of the feeding assembly 63 is not particularly described and limited, and optionally, the feeding assembly 63 includes a gripping member and a lifting driving member (such as a conventional lifting cylinder) slidingly engaged with the first linear motion module 62 for driving the gripping member to lift in a vertical direction. The lift drive member may optionally be slidably coupled to the first linear motion module 62 via rollers or slides, not specifically described or illustrated. The outer end of the transfer line 50 is outside the opening and fixed to the bracket 61, and the feeding assembly 63 is capable of being reciprocally moved and switched between a side of the bracket 61 near the tool transfer line 70 and above the outer end of the transfer line 50. Because the height of the tooling conveying line 70 may not be consistent with the height of the middle transfer line 50, the lifting type feeding assembly 63 is adopted so as to be capable of being adjusted according to the heights of the tooling conveying line 70 and the middle transfer line 50. The gripping members may alternatively be conventional air cylinder driven jaws, i.e. pneumatic jaws, the specific construction of which is not described or defined, as would be readily understood and effected by a person skilled in the art.

As shown in fig. 4, the transfer line 50 of the embodiment of the present utility model is identical to the belt line 21 of the conveying mechanism 20 in structure, and will not be described. In order to realize the positioning of the IV power-on test fixture 80 at the feeding position, the purpose of positioning is to make the fixture align, i.e. the two ends face the first direction, a stop mechanism 51 at the inner end of the transfer line 50 and positioning components are arranged at the two sides of the transfer line 50. For the stop mechanism 51, an existing conventional cylinder drives an L-shaped stop block which is lifted in a vertical direction, and an in-place detection device 511 for detecting whether the photovoltaic module 90 is in place or not, such as an existing conventional photoelectric sensor, is provided at an inner end of the L-shaped stop block, that is, a left end as shown in fig. 4. For the positioning component, in the embodiment of the utility model, one side is preferably fixed, and the other side is preferably movable, that is, the side positioning of the tooling at the feeding position is realized, so that the fixed side is only required to be fixed in advance according to the position when the pick-and-place mechanism 40 is moved to the feeding position without adjusting the position, and then the tooling deflected on the transfer line 50 is only required to be adjusted through the movable positioning component each time, so that the structure is simpler. Specifically, the positioning assembly includes a fixed stop 53 disposed on one side of the transfer line 50, i.e., the rear side as shown in fig. 4, and a movable first side pushing mechanism 52 disposed on the other side of the transfer line 50, i.e., the front side as shown in fig. 4. The first side pushing mechanism 52 is a push plate that is driven by a cylinder and slides along a slide rail in the X direction, and is identical to the third side pushing mechanism 24 described above (except that there is no positioning roller, but rather one push plate), and the specific structure is not described and limited, and is easily known and implemented by those skilled in the art. In the embodiment of the utility model, the in-place detection device 511 is electrically connected with the first side pushing mechanism 52, specifically, a driving cylinder of the first side pushing mechanism 52 for driving the push plate to move, and when the in-place detection device 511 detects that the tooling is in place, the driving cylinder drives the push plate to move along the-X direction shown in fig. 4, that is, the side where the baffle plate 53 is located is close to press against one end of the tooling and the other end of the tooling is pressed against the baffle plate 53, so that the positioning of the feeding position of the tooling is realized. As an alternative embodiment, both sides may be movable or fixed. When both sides are movable, that is, two first side pushing mechanisms 52 are provided, in order to facilitate that the two first side pushing mechanisms 52 do not need to be moved or adjusted when the picking and placing mechanism 40 moves to the feeding position at the inner end of the middle line 50, a photoelectric sensor needs to be additionally provided to detect the positions of the two groups of first clamps 441 and the second side pushing mechanisms 442 after the picking and placing mechanism 40 reaches the feeding position, so that the two first side pushing mechanisms 52 can be correspondingly pushed according to the detected position information, and do not need to be moved after being positioned, in this case, the positions of the two groups of first clamps 441 and the second side pushing mechanisms 442 on the first beam 14 are fixed, specifically, according to the length of the tool and the clamping position, the structure is relatively more complicated. When both sides are fixed, that is, two baffles 53 are provided, the distance between the two baffles 53 should be consistent with the length of the tooling or slightly longer, the two baffles 53 are set according to the two sets of the first clamps 441 and the second side pushing mechanisms 442 when the picking and placing mechanism 40 reaches the loading position, in this case, the positions of the two sets of the first clamps 441 and the second side pushing mechanisms 442 on the first beam 14 are also fixed, however, because the baffles on both sides are fixed, the space in the middle is limited, the loading mechanism 60 needs to be careful when the tooling is placed on the transfer line 50, and the tooling is more likely to be knocked when being transported on the transfer line 50.

Two inner side walls corresponding to the first direction, namely the inner sides of the front inner side wall and the rear inner side wall, in the machine shell 10 are respectively provided with two inner side beams 13 extending along the second direction, namely the Y direction shown in fig. 5, and a first beam 14 and a second beam 15 which are arranged on the two inner side beams 13 in a sliding manner and extend along the first direction, namely the X axis direction shown in fig. 5 at intervals in an opposite mode, second linear guide rails 131 extending along the second direction are respectively arranged on the two inner side beams 13, two ends of the first beam 14 and two ends of the second beam 15 are respectively connected to the second linear guide rails 131 on the two inner side beams 13 in a sliding manner, and the picking and placing mechanism 40 and the wire inserting mechanism 30 are respectively arranged on the first beam 14 and the second beam 15. Preferably, the power for moving the first beam 14 and the second beam 15 in the second direction is a servo-reduction motor 16. Specifically, as shown in fig. 5, synchronous pulley assemblies 18 are disposed at both ends of the first beam 14 and the second beam 15, and as exemplified by the first beam 14, a servo gear motor 16 is disposed at a middle position of the first beam 14, and an output end of the servo gear motor 16 is connected with two synchronous pulley assemblies 18 respectively disposed at both ends of the first beam 14 through two shafts 17 extending along a first direction (the two shafts 17 are coaxially connected in tandem along the first direction) to form a linkage assembly, and belts 19 respectively disposed on the two inner beams 13 and extending along a second direction and connected with the synchronous pulley assemblies 18 respectively corresponding thereto. Illustratively, the synchronous pulley assembly 18 at each end in the embodiment of the present utility model includes three synchronous pulleys sequentially spaced along the second direction, and the intermediate synchronous pulley is higher than the synchronous pulleys at both sides, the intermediate synchronous pulley is connected to the servo speed reducing motor 16 through the shaft 17, and the two synchronous pulleys at both sides are connected to the intermediate synchronous pulley through the belt 19, specifically, the belt 19 sequentially passes through the three synchronous pulleys along the transmission direction, that is, the second direction. This structure is used as a driving structure for the movement of the first beam 14 and the second beam 15 in the second direction, and is cheaper and less costly.

In the embodiment of the utility model, the first beam 14 is close to the side where the opening is located, and the second beam 15 is far away from the side where the opening is located, that is, the picking and placing mechanism 40 is disposed on the first beam 14, and the wire inserting mechanism 30 is disposed on the second beam 15.

As shown in fig. 6, the pick-and-place mechanism 40 includes a riser 41, a third linear guide 42, a mounting bracket 43, and a first clamping assembly 44. The standing plate 41 is provided on the side of the first cross member 14 facing the second cross member 15 and extends in the vertical direction. The third linear guide 42 is provided on a side surface of the vertical plate 41 facing the side of the second cross member 15 and extends in the vertical direction. The mounting frame 43 is slidably disposed on the third linear guide 42 and extends along the first direction, i.e., the X-axis direction as shown in the drawing, and a sliding seat and a sliding block (not shown) are provided between the mounting frame 43 and the third linear guide 42. The first clamping assembly 44 includes two sets of first clamps 441 and two sets of second side pushing mechanisms 442, where the two sets of first clamps 441 are disposed opposite to each other at intervals and are disposed in the middle of the two sets of second side pushing mechanisms 442 that are disposed opposite to each other at intervals. Of the two sets of first clamps 441 and the two sets of second side pushing mechanisms 442 in the embodiment of the present utility model, at least one set of first clamps 441 and one set of second side pushing mechanisms 442 are movable in the first direction with respect to the mounting frame 43. Preferably, in order to reduce the adjustment difficulty, the present utility model employs a set of first clamps 441 and a set of second side pushing mechanisms 442 for fixation, and the other set of first clamps 441 and second side pushing mechanisms 442 for movement. It is further preferred that a set of first clamps 441 and second side pushing mechanisms 442 on the side near the feed opening 11, i.e. the rear side as shown in fig. 6, be slidable with respect to the mounting frame 43, where such is arranged to correspond to the above-described arrangement of the photovoltaic module 90 positioned rearwardly. Specifically, as shown in fig. 7, a fourth linear guide 45 extending in the first direction, that is, in the X-axis direction in fig. 6, is provided at the bottom of the mounting frame 43, the first clamp 441 includes a first jaw member and the adjusting assembly 46, the second side pushing mechanism 442 includes a side pushing assembly and the adjusting assembly 46, and the structures of the first clamp 441 and the adjusting assembly 46 of the second side pushing mechanism 442 are the same. The first clamp 441 and the second side pushing assembly are both fixed to the fourth linear guide 45 by an adjusting assembly 46. The first jaw member may be selected from existing conventional pneumatic jaws, and the specific structure is not described or limited. The side-pushing assembly is also a push plate type structure driven by a cylinder, and similar to the structure of the first side-pushing mechanism 52, the specific structure is not described and limited. In the embodiment of the utility model, two groups of first clamps 441 are used for clamping two electrode copper blocks on the fixture, and two second side pushing mechanisms 442 are used for respectively compressing clamping joints at two ends of the fixture inwards, so that the two clamping joints shrink inwards to be shortened, and can be conveniently laid on the photovoltaic module 90, and after the pushing force is removed, the clamping joints can automatically stretch outwards to reset and automatically clamp on a first outer frame 921 and a second outer frame 922 of the photovoltaic module 90. For the adjusting assembly 46, in the embodiment of the present utility model, the adjusting assembly 46 of the first clamp 441 is taken as an example, and the adjusting assembly 46 of the second side pushing mechanism 442 has the same structure and is not described again. Specifically, as shown in fig. 8, the adjusting assembly 46 includes a fixed block 461, two clamping blocks 462, and an adjusting lever 463. The top of the fixing block 461 has two protrusions 4611, and a space is provided between the two protrusions 4611 to define a second installation space, and the first jaw member and the side pushing assembly are respectively fixed to the bottom of the fixing block 461 of the corresponding adjusting assembly 46. That is, the fixing block 461 is actually a U-shaped plate having a groove in the middle of the top. The two clamping blocks 462 are shaped to match the shapes of sliding grooves (not shown) on both sides of the fourth linear guide 45, and the two clamping blocks 462 are respectively disposed inside the two protrusions 4611 and slidably engaged with the fourth linear guide 45. One of the bumps 4611 is rotatably provided with an adjusting lever 463, and when the inner end of the adjusting lever 463 rotates inwards, the inner end of the adjusting lever 463 abuts against the side surface of the clamping block 462 on the side of the bump 4611, so that the clamping block 462 only abuts against the sliding groove on the fourth linear guide 45, and the first clamping jaw component or the side pushing component is fixed with the fourth linear guide 45. By such design, the distance between the two groups of first clamps 441 and the two groups of second side pushing mechanisms 442 can be adjusted according to the specific length on the tool and the distance between the two electrode copper blocks, so as to improve the suitability of the picking and placing mechanism 40. The adjusting lever 463 may be an existing conventional manual adjusting lever or an existing conventional electric adjusting lever, and the specific structure is not described and limited, and is easily known and implemented by those skilled in the art. Preferably an electrically operated adjustment lever.

As shown in fig. 9, the wire inserting mechanism 30 includes a fifth linear guide 31 and two sets of second clamping assemblies, which are driven to move along the fifth linear guide 31 by one driving mechanism 33 or each set is independently driven to move along the fifth linear guide 31 by one driving mechanism 33. The fifth linear guide 31 is provided on the side of the second cross member 15 facing the first cross member 14 and extends in the first direction, i.e., the X direction as shown in fig. 9. The two sets of second clamping assemblies are opposite and are slidably arranged on the fifth linear guide rail 31 at intervals. For the second clamping assembly, a second clamp 32 is included, as shown in fig. 9. Preferably, the two sets of second clamping assemblies are driven to move towards or away from each other by the same driving mechanism 33. The driving mechanism 33 is a conventional servo gear motor, and may be similar to the driving structure of the first beam 14 and the second beam 15 moving along the second direction, that is, a structure of a synchronous pulley assembly and a servo gear motor, which are not described herein. As shown in fig. 10, the second clamp 32 includes a fixing plate 321, a lifting cylinder 322, a rotating motor 323, a second jaw member 324, a CCD vision system 325, and a light source 326. The fixing plate 321 is slidably coupled to the fifth linear guide 31 by a slider or a slide rail (not shown) or the like. The lifting cylinder 322 is disposed on a side surface of the fixing plate 321, and the driving end of the lifting cylinder 322 is downward, that is, the driving end of the lifting cylinder 322 is disposed at the bottom end of the lifting cylinder 322 as shown in fig. 10, and the driving end of the lifting cylinder 322 can stretch along the vertical direction. The rotating motor 323 is disposed on the driving end of the lifting cylinder 322, and the driving end of the rotating motor 323 faces downward and can horizontally rotate around a vertical line, and the second jaw member 324 is disposed on the driving end of the rotating motor 323, that is, the bottom end of the rotating motor 323 as shown in fig. 10. The second jaw member 324 may alternatively be a conventional cylinder-driven jaw member, the specific construction of which is not described or defined in detail. The CCD vision system 325 is disposed on the fixed plate 321, located on one side of the lifting cylinder 322 and above the second clamping jaw member 324, and is used for obtaining the actual positions of the positive and negative electrode lugs on the photovoltaic module 90, that is, the first lug 941 and the second lug 942, and the light source 326 is disposed on the fixed plate 321 and located below the CCD vision system 325. The CCD vision system 325 is electrically connected to the driving mechanism 33, the lifting cylinder 322 and the second jaw member 324, and after the CCD vision system 325 detects the actual positions of the first connector lug 941 and the second connector lug 942, position signals are fed back to the driving mechanism 33, the lifting cylinder 322 and the second jaw member 324, and after the driving mechanism 33 and the lifting cylinder 322 receive the actual position information, corresponding feedback is made to drive the second jaw member 324 to perform actions such as traversing, lifting and rotating, so as to achieve position movement adjustment, until the second jaw member 324 reaches the position of the corresponding connector lug, and then clamping the connector lug is performed. The specific adjustment procedures and principles are not specifically described and defined and are not inventive at the point of this application but are known to those skilled in the art and are readily implemented.

The connector lug on the photovoltaic module 90 may be tilted, and if the second clamping jaw member 324 directly clamps the connector lug, the connector lug may be in a skew state, which is unfavorable for subsequent wire plugging operation, so that the connector lug needs to be pressed against the glass surface before the second clamping jaw member 324 closes and clamps the connector lug, and then the connector lug is clamped. In order to achieve the above object, the method according to the embodiment of the present utility model is as follows: a swage mechanism 327 is also provided on the side of the second jaw member 324. Specifically, as shown in fig. 11, the pressing mechanism 327 includes a stopper plate 3271, a sixth linear guide 3273, a pressing block 3274, an elastic member 3276, and a stopper (not shown). The limiting plate 3271 is mounted on the side of the second jaw member 324, a recessed channel (not labeled) extending in the vertical direction is formed on one surface of the limiting plate 3271 facing the second jaw member 324, a fixed sliding block 3272 is disposed on the inner wall of the channel, the sixth linear guide 3273 is disposed near the side of the second jaw member 324 but is not connected or fixed to the second jaw member, the sixth linear guide 3273 is slidably engaged with the sliding block 3272, the pressing block 3274 is mounted on the bottom end of the sixth linear guide 3273 through an L-shaped connecting block 3275, the pressing block 3274 is located between the two jaws of the second jaw member 324, the elastic member 3276 is disposed in the vertical direction and is composed of a guide rod and a spring sleeved on the guide rod, the top of the guide rod passes through the limiting plate 3271 upwards, a limiting member (such as a nut) for preventing the guide rod from falling off from the limiting plate 3271 due to self gravity is disposed on the top of the guide rod, and the bottom end of the guide rod is connected to the side of the connecting block 3275. In the free state of the press block 3274 not pressed against the lug, the press block 3274 has a tendency to displace downward under the action of gravity, the bottom ends of the press block 3274 are substantially flat with the bottom ends of the two second jaw members 324, and preferably the bottom ends of the press block 3274 are slightly lower than the bottom ends of the two second jaw members 324, and the lug first contacts the press block 3274. When the press block 3274 is pressed against the head of the connector lug, the press block 3274 is displaced upward, so that the spring is subjected to an upward pressing force to undergo compression deformation, and the compression deformation applies a downward reaction force to the press block 3274, so that the head of the connector lug is flattened by the press block 3274 against the glass panel 91 of the photovoltaic module 90. Thus, when the second jaw member 324 clamps the lug, the lug will not be skewed, and the plugging of the lug with the socket will be more convenient and smooth. Preferably, the press block 3274 is pressed against the top surface of the limit plate 3271 and the spring is in a compressed state in a free state not pressed against the terminal, thereby exerting a downward force on the press block 3274 so that the press block 3274 has a sufficient downward force when contacting the head of the terminal.

As an alternative embodiment, the automatic installation device according to the embodiment of the present utility model may not have an opening on the casing 10, and the feeding mechanism 60 moves above the casing 10 to implement tool entering and exiting the casing 10.

As another alternative embodiment, the automatic installation apparatus of the embodiment of the present utility model may not include the feeding mechanism 60, but may directly feed the tooling into the casing 10 from the opening on one side of the casing 10 through the tooling conveyance line 70 of the client.

As yet another alternative embodiment, the CCD vision system 325 may be provided not on the fixing plate 321 but on a third beam (not shown) between the first beam 14 and the second beam 15, and the CCD vision system 325 may be provided on the third beam.

In summary, the pick-and-place mechanism 40 in the embodiment of the present utility model has three degrees of freedom (XYZ three axes), and the wire inserting mechanism 30 has four degrees of freedom (XYZR four axes). The three-degree-of-freedom picking and placing mechanism 40 and the four-degree-of-freedom wire inserting mechanism 30 are adopted to replace the conventional six-degree-of-freedom robot, the occupied space is smaller, the installation efficiency is higher, and the wire connector is free from shielding during grabbing and is free from being affected by tool wear during insertion.

Example 2

The difference between the automatic installation equipment of the IV power-on test tool provided in this embodiment and the embodiment 1 is that the number of the second cross beams 15 in this embodiment is two, the two second cross beams 15 are disconnected, that is, separated, and the two groups of second clamping assemblies are respectively arranged on one second cross beam 15, and the movement of the two groups of second clamping assemblies is independent, that is, the two groups of second clamping assemblies are not constrained by each other. That is, the movements of the two sets of second clamping assemblies in the second direction in embodiment 1 are synchronized, while the movements of the two sets of second clamping assemblies in the second direction in this embodiment are independent. So designed, because the positions of the two lugs are random on the glass panel 91, that is, not necessarily on the same horizontal line, the two groups of second clamping assemblies may not be capable of clamping the two lugs at the same time, and may need to clamp step by step, that is, the lug closer to the photovoltaic assembly 90 is firstly clamped, and then the lug further away from the photovoltaic assembly 90 is clamped, while the two second clamping assemblies are independently moved without being affected by the design of the embodiment, so that the synchronous clamping of the two lugs can be realized, and the production efficiency is higher. The applicant research tests show that the production efficiency can be saved by more than 1s by adopting the design of the embodiment, so that the time saving can reach an order of magnitude when the batch installation is carried out, namely the efficiency can be greatly improved. Specifically, referring to fig. 12 to 13, both the inner side cross members 13 and the second linear guide 131 and the belt 19 thereon are partially shown. The connection manner of the two second cross beams 15 and the two second linear guide rails 131 and the belt 19 is the same as that of the embodiment 1, and is not described in detail, but the difference is that in this embodiment, each second cross beam 15 must be provided with a servo speed reduction motor as an independent driving device for driving the corresponding second cross beam 15 to move along the second direction. Because the two second beams 15 are disconnected, in order to ensure the stability of the second beams 15, the bottoms of the ends of the two second beams 15 close to each other should be additionally provided with a sliding support structure, specifically, the sliding support structure includes a support frame 100 fixedly connected with the casing 10 and a seventh linear guide rail 101 disposed on the support frame 100 and extending along the second direction, and the two second beams 15 are respectively in sliding fit with the corresponding seventh linear guide rail 101. In order to improve the stability and reliability of the support 100, the support 100 is provided with diagonal braces 102 on the left side as shown in fig. 12. However, the diagonal braces 102 of this configuration are designed to interfere with the corresponding second beam 15 and the wire insertion mechanism 30 thereon, i.e., to affect the travel of the second beam 15. Preferably, as shown in fig. 13, the diagonal braces 102 are disposed at the bottom of the support frame 100, and as fig. 13 is a top view, the diagonal braces 102 are hidden by the support frame 100 and are not shown. So designed, the diagonal brace 102 does not interfere with the second beam 15 and the wire insertion mechanism 30 thereon, i.e., does not affect the travel of the second beam 15. One disadvantage of this solution is however that the cost is higher than in example 1.

The embodiment of the utility model provides an IV power-on test tool, which comprises the following steps:

the CCD vision system 325 automatically acquires the actual positions of the positive and negative lugs on the photovoltaic module 90, and the wire inserting mechanism 30 respectively clamps the two lugs after adjusting the positions of the two groups of second clamping assemblies according to the actual positions;

the two groups of first clamping assemblies 44 of the taking and placing mechanism 40 grab the IV power-on test fixture 80 from the feeding position, and the two groups of second side pushing mechanisms 442 move the elastic clamping joints at the two ends of the IV power-on test fixture 80 to the position above the fixture mounting position of the photovoltaic module 90 after inwards shrinking;

the plug wire mechanism 30 inserts two connector lugs into two plug sockets of the IV power-on test fixture 80 at the same time;

the taking and placing mechanism 40 downwards places the IV power-on testing tool 80 into the photovoltaic module 90, and elastic clamping connectors at two ends of the IV power-on testing tool 80 are reset and clamped on the frame. In the above method steps, the wire clamping and wire inserting actions of the wire inserting mechanism 30 and the wire clamping and feeding actions of the wire clamping and feeding tool of the wire clamping and feeding mechanism 40 are not sequential. Preferably, in order to further improve the production efficiency, the wire clamping and wire inserting operation of the wire inserting mechanism 30 and the wire clamping and feeding operation of the wire clamping and feeding mechanism 40 are performed simultaneously.

According to some preferred embodiments of the utility model, the method further comprises the steps of:

the photovoltaic module 90 is conveyed into the casing 10 by the conveying mechanism 20 to be positioned; this step may be performed before or after the wire clamping operation of the wire inserting mechanism 30 and the wire clamping and loading operation of the pick-and-place mechanism 40.

The transfer mechanism 20 transfers the patch cord connected and installed IV powered test fixture 80 and photovoltaic module 90 together out of the enclosure 10 to connect with the IV test instrument and perform subsequent testing.
