Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic product processing, and its name is an automatic feeding system for a connector. Background Art

[0002] Photovoltaic connectors are key accessories for solar cell modules. One end is used to connect the junction box, and the other end has a male connector or a female connector for realizing the series clustering of single photovoltaic modules. In the prior art, connectors need to be assembled jointly through multiple devices: first, the cable is cut to the required length on a wire cutting machine and the end is peeled, then the processed cable is transferred to a riveting machine to press and fix the wire core of the cable with the terminal, and then the pressed terminal is transferred to a nut machine, the terminal is inserted into the connector, and the nut machine is operated to tighten the nut of the connector, finally completing the assembly of the connector.

[0003] In the prior patent application No. 202110685254.1, there is disclosed "a photovoltaic connector wire harness integrated machine", which includes a frame. A wire cutting and peeling unit, a terminal riveting unit, and a nut tightening unit are sequentially arranged on the frame. The nut tightening unit includes a tightening mechanism and a feeding mechanism. The tightening mechanism is connected to the frame through a vertical plate. A feeding hole is opened on the vertical plate, and the feeding mechanism is arranged on the back of the vertical plate. The feeding outlet of the feeding mechanism is butted against the feeding hole; on the front of the vertical plate, there is a tightening mechanism for tightening the nut fed by the feeding mechanism, and the tightening mechanism is connected to the feeding hole through a flange bearing.

[0004] In the prior art, workers often use a manipulator to take a single connector component from a tray for placing connector components, and then send it into the feeding mechanism of the above technical solution. Since the connector components on the tray are in a vertical state, the feeding mechanism needs to turn them into a horizontal state before feeding, which undoubtedly increases the structural complexity of the feeding mechanism, and with the turning action, the feeding time is also increased, and the practicability needs to be improved. The use of the manipulator also increases the equipment cost.

[0005] Therefore, it is necessary to provide an automatic feeding system for a connector, which can achieve the function of automatic feeding. Summary of the Invention

[0006] The purpose of the present invention is to provide an automatic feeding system for a connector to solve the problems raised in the above background art.

The semi-circular baffles are made of rubber plates;

A number of connector components are all in a horizontal state and stacked in the trapezoidal funnel frame. Under the action of a pair of inclined surfaces on the lower side of the trapezoidal funnel frame, the connector components are all converged on the screening rotating cylinder. As the screening rotating cylinder rotates, a single connector component is continuously screened from a number of connector components and sent into the lower transition part. Thus, a number of connector components are stacked in a row in the transition part.

Of course, they are only examples and are not intended to limit the present application.

[0044] Please refer to Figures 1-10 , the present invention provides a technical solution: an automatic feeding system for a connector, including a screening part 3, a transition part 4, a base 5, a support part, and a pushing part 1; where:

[0045] The screening part 3 includes a trapezoidal funnel frame 301. An inlet is provided on the upper side of the trapezoidal funnel frame 301. A number of connector components 6 are stacked and placed inside the trapezoidal funnel frame 301. The connector components 6 are all placed in a horizontal state. A screening rotating cylinder 302 is provided on the lower side of the trapezoidal funnel frame 301. The screening rotating cylinder 302 is used to screen out a single connector component 6 from the trapezoidal funnel frame 301 and sequentially send it into the transition part 4.

[0046] The transition part 4 is arranged at the lower end of the screening part 3. The connector components 6 are stacked in an orderly manner in a column in the transition part 4. The transition part 4 is used to screen out a single connector component 6 from a column of stacked connector components 6 and intermittently send it into the lower support part.

[0047] The support part is arranged on the base 5. The support part is arranged on the lower side of the transition part 4. The support part is used to pick up a single connector component 6 and support and position it.

[0048] The pushing part 1 is arranged on one side of the support part. The pushing part 1 is used to push a single connector component 6 on the upper side of the support part into the next process for processing.

[0049] Specifically, the staff previously placed several connector components 6 into the trapezoidal funnel frame 301 in the screening section 3 through the feeding port. Alternatively, existing technologies such as conveyor belt components can be used to continuously transport the connector components 6 into the trapezoidal funnel frame 301. The several connector components 6 are stacked horizontally in the trapezoidal funnel frame 301. Under the action of a pair of inclined surfaces on the lower side of the trapezoidal funnel frame 301, the connector components 6 converge on the screening rotating cylinder 302. As the screening rotating cylinder 302 rotates, single connector components 6 are continuously screened out from the several connector components 6 and fed into the lower transition section 4. Thus, the several connector components 6 are stacked in a column in the transition section 4. Then, the transition section 4, in coordination with the timing of intermittent feeding in the feeding section 1, orderly and intermittently screens single connector components 6 onto the support section. Then, the feeding section 1 pushes them into the next processing step, thereby completing the overall assembly of the connector. This application does not require the use of a manipulator and a tray, saving equipment costs. The screening section 3 and the transition section 4 can complete the continuous automatic feeding of the connector components 6. Moreover, the initial state of the connector components 6 is a horizontal state, and there is no need for a complex feeding mechanism to flip and feed them. The structure is simple and the operation is convenient, improving the feeding efficiency.

[0050] On both sides of the lower end of the trapezoidal funnel frame 301, a pair of arc-shaped plates 303 are fixedly connected. The centers of the pair of arc-shaped plates 303 coincide with the center of the screening rotating cylinder 302. A number of arc-shaped grooves 304 are formed on the outer surface of the screening rotating cylinder 302. The arc-shaped grooves 304 are used to screen in single connector components 6. One end of the screening rotating cylinder 302 is provided with a first motor 305. The first motor 305 is fixed on the outer side wall of the trapezoidal funnel frame 301. The first motor 305 is used to drive the screening rotating cylinder 302 to rotate. The distance between the bottom of the arc-shaped groove 304 and the arc-shaped plate 303 is equal to the diameter of a single connector component 6. When the screening rotating cylinder 302 rotates, several connector components 6 in the trapezoidal funnel frame 301 are screened into the arc-shaped grooves 304 and brought into the arc-shaped plate 303, and then fall into the lower transition section 4 along the arc-shaped plate 303.

[0051] Specifically, since the connector components 6 are generally columnar, therefore, they can be stacked stably in the trapezoidal funnel frame 301 in a horizontal state. Moreover, the screening rotating cylinder 302 blocks the falling outlet of the trapezoidal funnel frame 301. The gap between the screening rotating cylinder 302 and the arc-shaped plate 303 is not large enough for the connector components 6 to fall. Additionally, a number of arc-shaped grooves 304 are formed on the outer side of the screening rotating cylinder 302. As the screening rotating cylinder 302 rotates, single connector components 6 continuously fall into the arc-shaped grooves 304 and move along the arc-shaped plate 303 with the screening rotating cylinder 302, and finally fall into the lower transition section 4 (as Figure 2 shown), thereby completing the separate screening of the connector components 6.

[0052] The transition part 4 includes a discharge channel 401 which is arranged as a vertical square channel. The upper end of the discharge channel 401 is connected to the arc-shaped plate 303. A column of connector components 6 is vertically stacked in the discharge channel 401. The lower end of the discharge channel 401 is provided with a cylindrical shell 402. The lower end of the cylindrical shell 402 is provided with a discharge port 403. Inside the cylindrical shell 402, there is a material receiving cylinder 404. One side of the material receiving cylinder 404 is provided with a material receiving groove 405. The axis of the material receiving cylinder 404 coincides with the axis of the cylindrical shell 402. The distance from the bottom of the material receiving groove 405 to the cylindrical shell 402 is equal to the diameter of a single connector component 6. A plurality of support columns 7 are fixedly connected to the lower side of the outer side of the cylindrical shell 402. The lower ends of the support columns 7 are fixedly connected to the base 5. One end of the material receiving cylinder 404 is provided with a driving member to drive it to rotate.

[0053] Specifically, since the screening part 3 screens out a single one from a number of stacked connector components 6 by the rotation of the screening rotating cylinder 302, it has a certain degree of uncertainty itself and cannot ensure that the connector component 6 can be accurately screened every time. When directly used for feeding the feeding part 1, it may cause that when the feeding part 1 pushes the material, there is no corresponding connector component 6 falling onto the supporting part, resulting in chaos in the process. Therefore, the transition part 4 is set up for transition. The single connector components 6 falling from the screening part 3 fall into the discharge channel 401 in sequence to form a column. The cylindrical shell 402 and the material receiving cylinder 404 are arranged in the same way as the screening part 3, but only one material receiving groove 405 is provided on the material receiving cylinder 404. This enables the accurate control of the timing of receiving the connector component 6 and its falling from the discharge port 403 when the material receiving cylinder 404 rotates. And since the connector components 6 are arranged in a column in the discharge channel 401, compared with the screening part 3, the stability and accuracy of screening are greatly improved. By only controlling the rotation speed of the driving member driving the material receiving cylinder 404, the control of the feeding timing can be realized, and in cooperation with the feeding part 1, effective feeding can be achieved.

[0054] The supporting part includes a supporting platform 2. On the upper side of the supporting platform 2, there is a limiting groove 201 which is correspondingly arranged with the discharge port 403. The limiting groove 201 is used to limit the connector component 6. The axis of the limiting groove 201 coincides with the axis of the connector component 6. The support column 7 passes through the supporting platform 2 and is in sliding fit with it. The lower end of the supporting platform 2 is provided with a linear driving component.

[0055] Specifically, the connector component 6 falling from the discharge port 403 falls into the limiting groove 201 on the supporting platform 2 to achieve positioning, which is convenient for the feeding part 1 to push. And since the feeding part 1 will surely contact the supporting platform 2 when pushing, a linear driving component is arranged on the lower side of the supporting platform 2, so that when the feeding part 1 pushes the connector component 6, the supporting platform 2 descends to avoid interference and will not hinder the feeding part 1.

[0056] One end of the support platform 2 is fixedly connected with a rack 202. One side of the rack 202 is meshed and connected with a first gear 203. The center of the first gear 203 is fixedly connected with a rotating rod. The rotating rod passes through the cylindrical shell 402 and is rotatably connected thereto. The rotating rod is connected with the material receiving cylinder 404. The axes of the rotating rod and the material receiving cylinder 404 coincide with each other. The support platform 2 controls the material receiving and discharging of the material receiving cylinder 404 by moving up and down.

[0057] Specifically, when the material receiving cylinder 404 sends the connector assembly 6 to the support platform 2, the material receiving groove 405 is downward at this time. Then, when the support platform 2 is driven by the linear drive assembly to move downward for avoidance, the support platform 2 is guided along a plurality of support columns 7, driving the rack 202 on one side to descend simultaneously. The rack 202 meshes with the first gear 203 to drive the first gear 203 to rotate, thereby driving the rotating rod and the material receiving cylinder 404 to rotate, so that the material receiving cylinder 404 turns the material receiving groove 405 back to the upper end for material receiving. Then, after the pushing part 1 finishes pushing the material, the support platform 2 rises and resets. The rack 202 meshes with the first gear 203 in the reverse direction, and the first gear 203 rotates in the reverse direction, making the material receiving groove 405 rotate downward again, so that the connector assembly 6 in the groove falls onto the support platform 2 again. Repeating this process realizes orderly operation, and setting a single linear drive assembly can drive the support platform 2 and the material receiving cylinder 404 to work, saving costs.

[0058] The pushing part 1 includes a pushing column 101. A clamping groove 102 is formed inside the pushing column 101. The clamping groove 102 is correspondingly arranged with the limiting groove 201. A positioning rod 103 is arranged at the center of the clamping groove 102. The positioning rod 103 is inserted into the inside of the connector assembly 6 for positioning, and the outside of the connector assembly 6 is clamped into the clamping groove 102 for limiting.

[0059] Specifically, when pushing the material is required, the pushing column 101 moves towards the connector assembly 6 on the support platform 2. Since the support platform 2 will move downward for avoidance, before the support platform 2 moves downward, the positioning rod 103 first inserts into the inside of the connector assembly 6 to support it, preventing the support platform 2 from driving it to descend simultaneously and further ensuring the neutral position of the connector assembly 6.

[0060] A circular ring part 104 is arranged on one side of the support platform 2. The lower end of the circular ring part 104 is connected with the base 5. A pair of semi-circular baffles 105 are arranged inside the circular ring part 104. One end of the semi-circular baffle 105 is fixedly connected with a semi-cylindrical sleeve 106. The axes of the semi-cylindrical sleeve 106, the circular ring part 104 and the limiting groove 201 coincide with each other. The connector assembly 6 is pushed by the pushing column 101 and inserted into the inside of a pair of semi-cylindrical sleeves 106 and blocked by the semi-circular baffles 105. The semi-circular baffles 105 are made of rubber plates;

[0061] A pair of first beveled arc plates 107 are fixedly connected to the outer side of the pushing column 101. A second beveled arc plate 108 is disposed opposite to the inclined end of the first beveled arc plate 107. The inner side of the second beveled arc plate 108 is slidably engaged with the outer side of the pushing column 101. One end of the second beveled arc plate 108 is fixedly connected to a pushing plate 109. A guide rod 110 is disposed through the inner side of the pushing plate 109. One end of the guide rod 110 is fixedly connected to the pushing column 101, and the other end of the guide rod 110 is fixedly connected to a retaining piece 111. One end of the pushing plate 109 is fixedly connected to a push rod 112. A circular hole groove is formed at one end of the push rod 112. A first spring is disposed in the circular hole groove. One end of the first spring is connected to the retaining piece 111, and the retaining piece 111 slides along the circular hole groove;

[0062] A pair of fixed arc plates 113 are fixedly connected to the outer side of the pushing column 101.

[0063] Specifically, after the connector assembly 6 is inserted by the positioning rod 103, with the pushing of the pushing column 101, the connector assembly 6 is pushed into a pair of semi-cylindrical sleeves 106, and finally abuts against the sides of a pair of semi-circular baffles 105. As the head end of the connector assembly 6 is limited, the pushing column 101 continues to push, so that the clamping groove 102 is sleeved on the outer side of the connector assembly 6, thereby limiting it;

[0064] Since the connector assembly 6 itself is not a standard cylinder, the inner shape of the clamping groove 102 is not a standard cylindrical groove either, but a corresponding inner cavity shape matching the outer shape of the connector assembly 6, which is used to limit the position of the connector assembly 6 to prevent the connector head from rotating during the tightening of the nut. Therefore, when the clamping groove 102 is snapped onto the outer side of the connector assembly 6, it may be impossible for the connector assembly 6 to be correctly snapped into the clamping groove 102 due to the misalignment of the corresponding shape positions on both sides, resulting in Figure 8In the shown state, the connector assembly 6 still abuts against the semi-circular baffle 105 at this time, and the head end of the pusher post 101 also abuts against the outer side of the connector assembly 6. One end of the pusher post 101 is connected with a guide rod 110, a pushing plate 109 and a push rod 112. A driving member is provided to push the push rod 112, so that the push rod 112 pushes the pusher post 101 to move. When the head end of the pusher post 101 abuts against the outer side of the connector assembly 6, the push rod 112 can continue to push the pushing plate 109, and the pushing plate 109 pushes a pair of second beveled arc plates 108. The hypotenuse of the second beveled arc plate 108 is arranged opposite to the hypotenuse of the first beveled arc plate 107. One end of the pusher post 101 abuts against the outer side of the connector assembly 6, so that the first beveled arc plate 107 rotates correspondingly along the hypotenuse of the second beveled arc plate 108, thereby driving the pusher post 101 and the inner clamping groove 102 to rotate. The connector assembly 6 is abutted against the semi-circular baffle 105 made of rubber material, and the connector assembly 6 itself is kept from rotating through a large frictional force. When the clamping groove 102 rotates to a certain position, the connector assembly 6 can be successfully clamped into the clamping groove 102.

[0065] Furthermore, a first spring is also provided to facilitate the reset of the first beveled arc plate 107 and the second beveled arc plate 108. And when the pusher post 101 rotates, it will drive the guide rod 110 to rotate correspondingly. Therefore, a torsion spring member 117 is also provided between the pushing plate 109 and the pusher post 101, so that when the pusher post 101 and the first beveled arc plate 107 are reset, while returning to the corresponding position, they also rotate back to the initial angle, which is convenient for clamping the connector assembly 6 next time.

[0066] A pair of fixed arc plates 113 are also provided on the outer side of the pusher post 101. When the first beveled arc plate 107 rotates along the second beveled arc plate 108, it drives the fixed arc plates 113 to rotate together until the fixed arc plates 113 contact the second beveled arc plate 108, positioning the pusher post 101 that rotates a certain angle. And in the initial state, the fixed arc plates 113 also contact the second beveled arc plate 108, which is used to limit the positions of the pusher post 101 and the connector assembly 6 and prevent the pusher post 101 from rotating along with the nut during the tightening process.

[0067] A ring 114 is fixedly connected to the outer side of one end of the pusher post 101 close to the semi-cylindrical sleeve 106. One end of the ring 114 is set as an inclined surface, and the inner sides of one ends of a pair of semi-cylindrical sleeves 106 are set as arc-shaped bevel chamfers. The inclined surface is arranged opposite to the arc-shaped bevel chamfer. Both ends of the semi-cylindrical sleeve 106 are fixedly connected with connecting strips 115. A plurality of guide rods 116 are penetrated through the inner sides of the connecting strips 115. Both ends of the guide rods 116 are fixedly connected with the ring member 104. A second spring is arranged on the outer side of the guide rods 116, and both ends of the second spring are respectively connected with the connecting strips 115 of the ring member 104.

[0068] Specifically, when the connector assembly 6 is successfully snapped into the clamping groove 102, the pushing column 101 can continue to move towards the semi-cylindrical sleeve 106 at this time, so that the inclined surface of the annular ring 114 contacts the chamfer of the semi-cylindrical sleeve 106 (as Figure 9 shown), causing a pair of semi-cylindrical sleeves 106 to separate to both sides along the inclined surface of the annular ring 114. The connecting strip 115 moves along the guide rod 116 for guiding, and drives a pair of semi-circular baffles 105 to separate, and then the connector assembly 6 can be pushed into the processing procedure for assembly.

[0069] The linear drive assembly includes a first threaded rod 8. A threaded sleeve 801 is threadedly connected to the upper side of the first threaded rod 8. The upper end of the threaded sleeve 801 is connected to the support platform 2. The lower end of the threaded sleeve 801 is fixedly connected to a crown gear 802. The lower end of the crown gear 802 is rotatably connected to the base 5. A second gear 803 is meshed with the upper side of the crown gear 802. One end of the second gear 803 is fixedly connected to a second threaded rod 804. One end of the second threaded rod 804 is provided with a second motor 805. The second motor 805 is connected to the base 5. A moving plate 806 is slidably fitted to the upper side of the base 5. The second threaded rod 804 passes through the moving plate 806 and is threadedly connected thereto. The upper end of the moving plate 806 is connected to the push rod 112. A telescopic column 807 is provided between the moving plate 806 and the base 5.

[0070] Specifically, when it is necessary for the linear drive assembly to drive the support platform 2 to descend, only need to start the second motor 805. The second motor 805 drives the second threaded rod 804 and the second gear 803 to rotate. The second gear 803 meshes with the crown gear 802 to move, so that the crown gear 802 drives the first threaded rod 8 to rotate. The first threaded rod 8 is threadedly connected to the threaded sleeve 801, so that the threaded sleeve 801 drives the support platform 2 to descend. At the same time, when the second threaded rod 804 rotates, the second threaded rod 804 is threadedly connected to the moving plate 806. Under the guiding action of the telescopic column 807, the moving plate 806 pushes the push rod 112, and the connector assembly 6 is pushed into the processing procedure. That is, the descent of the support platform 2 is synchronized with the pushing of the pushing part 1, with good synchronization, and only one second motor 805 is used to complete the operation of two functional components, improving the utilization rate and saving costs.
