For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] The utility model provides a photovoltaic module junction box taking and placing mechanism, which is used to install the junction box to the junction box installation position of the photovoltaic module. Figure 1 and Figure 2 , the mechanism comprises a wire box clamping group 1 and a lead clamping group 2;

[0046] The junction box clamping group 1 is used to clamp the junction box;

[0047] The lead clamping group 2 includes a middle clamping arm 21, two side clamping arms 22, a push rod 23, a driving source 1 24 and a driving source 2 25, wherein:

[0048] The middle clamping arm 21 is arranged in the middle of the two side clamping arms 22, and the driving source 1 24 is used to drive the two side clamping arms 22 to move toward or away from each other; the push rod 23 passes through the middle clamping arm 21 and the two ends pass through the two side clamping arms 22 respectively; a lead wire accommodating groove 222 is arranged on a surface of each side clamping arm 22 close to the middle clamping arm 21, and the driving source 2 25 is used to drive the driving source 1 24 and the two side clamping arms 22 to move horizontally synchronously along a direction approaching or away from the wire box clamping group 1.

[0049] The working principle of the above mechanism is:

[0050] In the initial state, the driving source 1 24 drives the two side clamping arms 22 to open, and the driving source 2 25 drives the driving source 1 24 and the two side clamping arms 22 to be close to the wire box clamping group 1;

[0051] Reference Figure 3 and Figure 4, the lead clamping group 2 is controlled to move as a whole by the driving device, so that the middle clamping arm 21 is inserted between the two leads at the installation position of the wire box. At this time, one of the leads is located between one of the side clamping arms 22 and the middle clamping arm 21, and the other lead is located between the other side clamping arm 22 and the middle clamping arm 21;

[0052] Reference Figure 5 , continue to push the middle clamping arm 21 and the two side clamping arms 22 forward horizontally, thereby driving the push rod 23 to move forward. If the lead is in a backward tilted state at this time, the push rod 23 can push the backward tilted lead forward to a vertical state;

[0053] Reference Figure 6 Then, the driving source 1 24 drives the two side clamping arms 22 to close, and the two leads are clamped between the two side clamping arms 22 and the middle clamping arm 21, and are located in the lead receiving grooves 222 on the two side clamping arms 22;

[0054] Reference Figure 7 Then, the driving source 25 drives the driving source 1 24 and the two side clamping arms 22 to move in a direction away from the wire box clamping group 1 (i.e., move backward). If the lead wire is in a forward tilted state at this time, the front side groove wall of the lead wire accommodating groove 222 can push the forward tilted lead wire backward to a vertical state; Figure 7 As shown, the front and rear ends of the lead wire are clamped between the front groove wall of the lead wire accommodating groove 222 and the push rod 23, and the two sides of the lead wire along the thickness direction are clamped between the groove bottom of the lead wire accommodating groove 222 and the middle clamping arm 21, so it will not move, which is convenient for the subsequent installation of the junction box.

[0055] It should be noted that the above-mentioned driving device can be a three-axis moving device such as a guide rail slider, or a three-axis or six-axis robot. It only needs to be able to move the components of the mechanism to the set position, and there is no limitation here.

[0056] In summary, during the operation of the above mechanism, the push rod 23 can push the backward-leaning lead forward to a vertical state, and the front side groove wall of the lead receiving groove 222 can push the forward-leaning lead backward to a vertical state, so that the lead tilted forward and backward can be straightened; at the same time, during the process of inserting the free end of the lead into the junction box, the lead is clamped between the middle clamping arm 21 and the side clamping arm 22, so it cannot tilt to both sides. Since the lead is basically in a vertical state under the clamping of the lead clamping group 2, the lead can be smoothly inserted into the junction box clamped on the junction box clamping group 1, reducing the error rate during the installation of the junction box, thereby improving the installation efficiency of the junction box.

[0057] Reference Figure 4 and Figure 5The middle clamping arm 21 is provided with a first through hole 211, each side clamping arm 22 is provided with a second through hole 221, and the push rod 23 sequentially passes through the second through hole 221 on one side clamping arm 22, the first through hole 211, and the second through hole 221 on the other side clamping arm 22. Limiting structures are respectively provided at both ends of the push rod 23, and the limiting structures prevent the push rod 23 from escaping from each through hole.

[0058] Optionally, the limiting structure on the push rod 23 can be a fastener such as a nut or a bayonet, or a radial protrusion on the push rod 23. In this embodiment, one end of the push rod 23 is provided with a radial protrusion; the other end of the push rod 23 passes through each through hole in sequence, and the protruding part is connected with a nut.

[0059] With the above-mentioned structure, when the two side clamping arms 22 move toward or away from each other, the push rod 23 can slide relative to the two side clamping arms 22 .

[0060] On the basis of the above structure, the first through hole 211 is adapted to the outer diameter of the push rod 23, and the first through hole 211 can limit the radial displacement of the push rod 23;

[0061] The second through hole 221 is in the shape of a long hole, and a portion of the push rod 23 is slidably disposed in the second through hole 221 .

[0062] In the above structure, the second through hole 221 reserves room for the push rod 23 to move; when the two side clamping arms 22 translate backward, the push rod 23 will not translate backward with the two side clamping arms 22 due to the restriction of the first through hole 211, that is, the radial position of the push rod 23 remains unchanged during the process of the two side clamping arms 22 moving backward.

[0063] Reference Figure 6 and Figure 7 A tapered portion 212 is provided at one end of the middle clamping arm 21 close to the lead clamping group 2. The tip of the tapered portion 212 faces forward, which is conducive to the middle clamping arm 21 being smoothly inserted between two opposite leads.

[0064] Reference Figure 8 and Fig. 9 The lead clamping group 2 also includes a driving source three 26 and a driving source four 27, wherein:

[0065] The driving source three 26 is used to drive the driving source two 25 to move horizontally in a direction close to or away from the wire box clamping group 1; the driving source four 27 is used to drive the driving source three 26 to rise and fall.

[0066] The provision of the driving source three 26 and the driving source four 27 improves the mobility of the middle clamping arm 21 and the two side clamping arms 22 in space, making the control method of the lead clamping group 2 more flexible.

[0067] On the basis of the above mechanism, the lead clamping group 2 further includes a connecting plate 28 , the power output end of the driving source three 26 is connected to the connecting plate 28 , and the middle clamping arm 21 and the driving source two 25 are mounted on the connecting plate 28 .

[0068] Specifically, the rear end of the middle clamping arm 21 is fixed to the connecting plate 28 by fasteners such as screws; the two power output ends of the driving source 1 24 are respectively connected to the two side clamping arms 22, and the cylinder part of the driving source 1 24 is fixed to the power output end of the driving source 2 25; the cylinder part of the driving source 2 25 is fixed to the connecting plate 28; the connecting plate 28 is fixed to the power output end of the driving source 3 26, and the cylinder part of the driving source 3 26 is fixed to the power output end of the driving source 4 27.

[0069] Analyzing the above structure, the structure of the middle clamping arm 21 and the cylinder part of the driving source 2 25 are fixed on the connecting plate 28, and the power output end of the driving source 2 25 can drive the driving source 1 24 and the two side clamping arms 22 to move forward and backward relative to the connecting plate 28.

[0070] Reference Fig.10 The wire box clamping group 1 includes a driving source 5 11 and a pair of wire box clamps 12, and the two power output ends of the driving source 5 11 are respectively connected to the two wire box clamps 12; the mechanism also includes a lead wire flattening group 3, which is arranged between the pair of wire box clamps 12, and includes a driving source 6 31 and a pair of lead wire flattening claws 32, and the power output end of the driving source 6 31 is connected to the pair of lead wire flattening claws 32.

[0071] Continue to refer to Fig. 9 The mechanism further comprises a first mounting seat 4, on which the wire box clamping group 1 and the lead wire leveling group 3 are both mounted;

[0072] And / or, the mechanism further includes a second mounting seat 5 , and the lead clamping group 2 is mounted on the second mounting seat 5 .

[0073] In this embodiment, the wire box clamping group 1, the lead flattening group 3 and the lead clamping group 2 are installed on the driving device through the first mounting seat 4 and the second mounting seat 5 to realize the movement of each component in the mechanism.

[0074] During operation, first, the driving device drives the lead clamping group 2 to move to the wiring box installation position through the second mounting seat 5, and clamps and fixes the lead at the wiring box installation position; then, the driving device drives the wiring box clamping group 1 and the lead leveling group 3 to move to above the lead at the wiring box installation position through the first mounting seat 4, aligns the lead position, and then moves the wiring box clamping group 1 and the lead leveling group 3 downward to drive the wiring box to descend; while the wiring box descends, the free end of the lead is inserted into the wiring box, and then the lead clamping group 2 releases the lead and leaves the wiring box installation position through the driving source three 26; the wiring box continues to be moved downward and placed at the wiring box installation position. At this time, the lead is completely inserted into the wiring box, and the lead leveling group 3 leveled the lead to complete the installation of the wiring box.

[0075] It should be noted that the above-mentioned driving sources can be any one of a pneumatic cylinder, an oil cylinder or an electric cylinder, and are not limited here. It is preferred to use a pneumatic cylinder as the driving source.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
