Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a connector pin bending device. Background Art

[0002] Electrical connectors are generally used to connect two active devices to transmit current or signals, and connector pins are common components of connectors. As electronic products develop towards miniaturization and intensiveness, there are often certain restrictions on the total height of the product. Connector pins with only a straight structure can no longer meet user needs, and more and more connector pins need to be bent.

[0003] For the prior art, reference may be made to the invention patent with application publication number CN117239511A, which discloses a fully automatic connector pin cutting and bending device, including: a frame; a pin tape reel and a connector shell feeding device arranged on the frame, for conveying the pin tape and the connector shell respectively; a pin cutting mechanism for cutting the tape edge of the pin tape; a pin transfer manipulator for transferring the pins with the tape edge cut to the pin insertion shaping device; a pin insertion shaping device for inserting the pins into the connector shell and shaping the pins; a pin bending device for bending the pins. Automatic insertion, shaping and bending of the pins are realized, which greatly improves production efficiency and ensures product quality.

[0004] The pin strip is a strip structure formed by connecting one end of a plurality of pin bodies to each other, and the pin bodies are formed by connecting the middle parts of a plurality of pins to each other, and a certain gap is maintained between two adjacent pins.

[0005] The pin body is prone to position displacement or even omission during installation, which will greatly reduce the quality of the connector. In addition, the pin body of the connector needs to be energized during use. Therefore, after installation, it is not known whether the pin body is energized and whether it meets the high voltage conditions when powered on. Therefore, the quality of the connector cannot be guaranteed. Summary of the invention

[0006] In order to improve the quality of a plug connector, the present application provides a connector pin bending device.

[0007] The present application provides a connector pin bending device, which adopts the following technical solution:

[0008] A connector pin bending device comprises a frame, a feeding mechanism, a cutting mechanism, a pin insertion mechanism and a bending mechanism arranged on the frame, and a detection device for testing the connector after the pin body is installed is also arranged on the frame, and the detection device comprises:

[0009] Two detection seats are arranged on the frame for sliding movement toward each other;

[0010] A test assembly is arranged on two detection seats, the test assembly is close to the pin body and is powered on first and then tested for connectivity, and the test assembly continues to perform a high voltage test after the test shows connectivity;

[0011] A moving component, used for driving the two detection seats to move;

[0012] The rejecting mechanism is electrically connected to the test assembly and rejects unqualified connectors according to the test results.

[0013] By adopting the above technical solution, the feeding mechanism transports the pin tape and the connector, the feeding mechanism transports the pin tape to the cutting mechanism, and the pin insertion mechanism clamps the pin tape, the cutting mechanism cuts the tape edge of the pin tape to form a pin body, the pin insertion mechanism transports and plugs the pin body into the connector, the connector is moved to the bending mechanism, the bending mechanism starts to bend the pin body, and the connector is transported to the detection device for detection.

[0014] The moving component drives the two detection sockets to approach each other, thereby driving the test component to approach and connect with the pin body. The test component first starts the power-on test to see if it is connected. If it is connected, it means that the pin body is installed and the position is installed correctly. Then the test component continues to power on to perform a high-voltage test on the pin body. If the test passes, the connector after the pin body is installed is qualified, otherwise it is unqualified. At the same time, if the power-on test is not connected, the connector after the pin body is installed is unqualified, and no subsequent high-voltage test is required. When the unqualified connector moves to the rejection mechanism, the rejection mechanism starts to reject the unqualified connector. At the same time, according to the number of unqualified connectors and the unqualified problems that occur, the staff can adjust the operating parameters of the equipment in time, thereby improving the quality of the connector.

[0015] Optionally, the test component includes:

[0016] Two connecting rod groups are respectively arranged on two detection seats and are respectively used to connect the two ends of the pin body;

[0017] A control part, used to first conduct an electrical test on the two connecting rod groups;

[0018] The high voltage testing machine is electrically connected to the control component and starts to perform high voltage testing on the pin body after the two connecting rod groups are tested to be energized.

[0019] By adopting the above technical solution, the two detection seats are close to each other to drive the two connecting rod groups to connect with the pin body. The control component is first powered on to detect whether the two connecting rod groups are connected through the pin body. If connected, the high-voltage tester is powered on to perform a high-voltage test on the pin body. If the test passes, it proves that the pin body is installed correctly, that is, a qualified product. If it is not connected or fails the high-voltage test, it is not a qualified product.

[0020] Optionally, the frame is provided with two limit plates located on both sides of the connector, and when the connector moves, it abuts against the two limit plates for limit and the top extends above the two limit plates, and the rejection mechanism includes:

[0021] The first and second rejecting plates are located on both sides of the two limiting plates and are both slidably arranged on the frame in a direction close to or away from the connector. A rejecting hole for the connector to pass through is provided on the limiting plate close to the second rejecting plate; the second rejecting plate is plugged and installed on the rejecting hole for positioning;

[0022] A driving assembly, used for driving the first and second rejection plates to move simultaneously so that the second rejection plate is separated from the rejection hole and the second rejection plate pushes the connector to fall from the rejection hole;

[0023] A collection assembly is used to separate the defective and qualified connectors for collection.

[0024] By adopting the above technical solution, the two limit plates limit the connector when it moves, so that the connector moves along a predetermined path, improving the position accuracy of the pin body during the process of being plugged into the connector, thereby improving the quality of the connector.

[0025] The driving component drives the rejection plate 1 and the rejection plate 2 to move. Therefore, in the initial state, the rejection plate 2 is plugged into the rejection hole, so that the connector continues to move along the predetermined path. When the unqualified products move to the rejection hole, the driving component drives the rejection plate 1 and the rejection plate 2 to move at the same time. The rejection plate 2 is disengaged from the rejection hole, and the rejection plate 1 pushes the connector through the rejection hole to fall into the collection component for collection. Then the driving component drives the rejection plate 1 and the rejection plate 2 to move back, so that the rejection plate 2 is plugged into the rejection hole for sealing, thereby achieving the rejection and collection of unqualified products.

[0026] Optionally, the collection component includes:

[0027] A collecting pipe, which is arranged on the machine body and is used to receive the rejected unqualified connectors;

[0028] Output guides are used to direct the output to qualified connectors.

[0029] By adopting the above technical solution, the rejected connectors, i.e., unqualified products, fall into the collection tube, while qualified products continue to move forward and are output through the output guide plate for collection, thereby achieving the separation of unqualified and qualified connectors.

[0030] Optionally, the feeding mechanism includes:

[0031] Conveying platform 1, used to support the connector and limit it through two limiting plates;

[0032] A conveyor belt is arranged on the frame;

[0033] A plurality of pushing blocks are arranged at intervals on the conveyor belt and are used to push the connector to move;

[0034] A vibrating plate loader is used to continuously convey the connectors to the conveying platform 1;

[0035] Conveyor platform 2, used to support the pin strip;

[0036] Two conveying rollers are rotatably arranged on the frame and are used to push the pin material strip to move. The conveying rollers convey the pin material strip to the pin insertion mechanism for clamping and the pin material strip is cut by the cutting mechanism.

[0037] By adopting the above technical solution, the vibration plate loader starts to transport the connector to the conveying platform, and the conveyor belt starts to drive multiple push blocks to move, and one push block pushes one connector to move, so as to realize step-by-step transportation of the connector. Therefore, multiple connectors are separated, so that each connector corresponds to an installation station. Therefore, the installation of the pin body can be gradually realized through multiple stations, and the distance between multiple adjacent connectors is kept consistent, which improves the accuracy of the installation process and reduces the phenomenon of pin body installation position offset or missing pins, thereby further improving the quality of the connector.

[0038] The pin material strip is conveyed by rotating two conveyor rollers, and the conveyor table 2 is used to support the plug-in material strip and drive the pin material strip to move to the cutting mechanism and the pin insertion mechanism. The pin insertion mechanism starts to clamp a single pin body, and then the cutting mechanism starts to cut the pin material strip, so that the pin body clamped by the pin insertion mechanism is separated from the pin material strip, and then the pin insertion mechanism drives the pin body away from the cutting mechanism and then plugs the pin body into the connector. Then the pin mechanism moves back to the cutting mechanism, the pin material strip continues to move forward, and the pin structure and the cutting mechanism continue to repeat, thereby realizing the transportation of the connector and the pin body and plugging the pin body into the connector, improving the stability and convenience during the installation of the pin body, and improving the quality of the connector.

[0039] Optionally, the rack is provided with a plurality of components for positioning the connector position, and the positioning components include:

[0040] A positioning seat, arranged on the limiting plate and located above the connector;

[0041] A limit seat is vertically slidably arranged on the positioning seat;

[0042] An electromagnet is arranged on a positioning seat;

[0043] The iron plate is arranged on the limit seat; when the conveyor belt is powered off and stops, the electromagnet is powered off at the same time and the limit seat is pressed against the connector under the action of gravity for positioning; or, the electromagnet is energized to adsorb the iron plate and disengage the limit seat from the connector to unlock it, and the conveyor belt starts to drive the connector to move.

[0044] By adopting the above technical solution, the electromagnet is energized to attract the iron plate upward for positioning, so that the iron plate moves up to drive the limit seat to move up and disengage from the connector, thereby unlocking the connector, and then the conveyor belt is energized to start driving the connector to move; when the connector needs to be positioned, the conveyor belt and the electromagnet are de-energized at the same time, and the limit seat falls downward under the action of gravity and presses on the connector for positioning, thereby reducing the probability of connector position deviation, and also reducing the probability of the connector falling off the conveyor belt platform during transportation, thereby improving the quality of the connector.

[0045] Optionally, the cutting mechanism includes:

[0046] A cutting table, which is arranged on the frame and is used to support and place the pin strip;

[0047] A movable seat is arranged on the frame for sliding up and down movement;

[0048] A sliding member, used for driving the moving seat to move;

[0049] A clamping seat is arranged on the movable seat and inserted into the pin strip for positioning;

[0050] The cutting seat is arranged on the movable seat. After the clamping seat is inserted into the pin strip for positioning, the cutting seat contacts the pin strip for cutting.

[0051] The counterweight seat is vertically slidably arranged on the moving seat through a limiting rod. In an initial state, the limiting rod is pressed against the moving seat for positioning under the action of the gravity of the counterweight seat.

[0052] By adopting the above technical scheme, the pin strip is moved to the cutting table, the pin insertion mechanism is used to clamp the pin body, the sliding member drives the moving seat to move downward, and the moving seat moves downward to drive the counterweight seat, the clamping seat and the cutting seat to move downward at the same time, and the counterweight seat is first placed on the pin strip for positioning, and then the clamping seat is inserted between the multiple pins of the pin body for positioning, and then the cutting seat and the edge of the pin strip are cut, the sliding member drives the clamping seat, the cutting seat and the counterweight seat to move upward, and then the pin insertion mechanism drives the pin body to move for plugging, and the counterweight seat and the clamping seat can be used to position the pin body from both horizontal and vertical directions, thereby improving the accuracy during cutting and improving the quality of the connector.

[0053] Optionally, the pin insertion mechanism includes:

[0054] A sliding seat 1 is slidably arranged on the frame along the moving direction of the pin strip;

[0055] Moving member 1, used for driving sliding seat 1 to move;

[0056] The second sliding seat is slidably arranged on the first sliding seat in a direction close to or away from the connector;

[0057] The second moving member is used for driving the second sliding seat to move;

[0058] A clamping assembly, arranged on the second sliding seat and used for clamping the pin body;

[0059] The re-pushing assembly is arranged on the frame and is used to push the installed pin body again and install the pin body in place.

[0060] By adopting the above technical scheme, the clamping assembly clamps the pin body, and the cutting machine cuts the pin strip so that the clamped pin body is separated from the pin strip, and the moving part one drives the sliding seat one to drive the sliding seat two, the clamping assembly, the moving part two and the pin body to move away from the pin strip at the same time, and then the moving part two drives the sliding seat two, the clamping assembly and the pin body to approach the connector, so that the pin body is plugged and installed on the connector, and the clamping assembly releases the clamping of the pin body, and the moving part two drives the sliding seat two and the clamping assembly to move away from the connector, and then the moving part one drives the sliding seat two and the clamping assembly to move back close to the pin strip, and the connector moves to the next station, and the re-pushing assembly starts to push the pin body to move, so that the pin body is installed in place, and then the connector continues to move, thereby realizing the installation of the pin and improving the accuracy of the pin body installation, thereby improving the quality of the connector.

[0061] Optionally, the bending mechanism includes:

[0062] A bending seat 1 is vertically slidably arranged on the frame;

[0063] A bending member 1, arranged on a bending seat 1 and located below the pin body;

[0064] A driving member 1, used for driving a bending seat 1 to move and driving a bending member 1 to move upward to perform a first bending on the pin body;

[0065] The second bending seat is slidably arranged on the frame in a direction close to or away from the pin body;

[0066] A second bending member is arranged on a second bending seat;

[0067] The second driving member is used to drive the second bending seat to move. The first bending member first bends the pin body and then moves downward, and the second bending member approaches the pin body to bend the pin body for the second time.

[0068] By adopting the above technical solution, the connector and the pin body are moved above the bending member 1, the driving member 1 drives the bending seat 1 and the bending member 1 to move upward to push the pin body upward for the first bending, the driving member 1 drives the bending seat 1 and the bending member to move downward, the driving member 2 drives the bending seat 2 and the bending member 2 to approach the pin body, and the bending member 2 bends the pin body for the second time, thereby completing the bending of the pin body.

[0069] Because the pin body is installed by horizontal plugging, and the bending part will abut against the connector for initial positioning after being pushed upward and bent, the probability of displacement of the pin body during the second bending can be greatly reduced, thereby improving the quality of the pin body during bending and further improving the quality of the connector.

[0070] Optionally, the frame is provided with two buffer assemblies respectively connected to two connecting rod groups, and the buffer assemblies include:

[0071] The first fixing seat and the second fixing seat are spaced apart and arranged on the frame, and both are insulators, and the second fixing seat is located on the side of the first fixing seat close to the first conveying platform;

[0072] A connecting member is arranged on the first fixing seat and is electrically connected to the control member, and the connecting rod group is slidably arranged on the second fixing seat and the connecting member;

[0073] A connecting plate, which is arranged on the connecting rod group and is made of insulating material;

[0074] An elastic member is connected to the first fixing seat and the connecting plate and drives the connecting plate to keep a tendency to approach the pin body and makes the connecting plate press against the second fixing seat for positioning;

[0075] The pressure sensor is arranged on the second fixing seat and is electrically connected to the control component. The connection plate presses against the pressure sensor. When the pressure of the pressure sensor is less than a specified value, the control component controls the rejection mechanism to reject the connector.

[0076] By adopting the above technical solution, when the pin body is plugged and installed on the connector, it is then bent by the bending mechanism. The bending mechanism can easily cause the pin body to come off the connector, causing the pin body to be displaced. Alternatively, the bending mechanism may not bend in place, causing the bending part of the pin body to protrude outward. In the above two states, the two connecting rod groups will still be connected to the pin body, indicating that they can be connected. However, in fact, the position of the pin body is not correct and the connecting rod group is easily damaged, thereby reducing the detection effect and the quality of the connector.

[0077] When in the working state, the two connecting rod groups can be connected to the pin body. If the above two situations are encountered, the pin body will push the connecting rod group and the connecting plate away from the fixing seat 2, thereby reducing the pressure value on the pressure sensor. When the pressure value is less than the specified value, it indicates that the connector is unqualified. The control part controls the rejection mechanism to reject the unqualified products, thereby further improving the quality of the connector. The elastic part can achieve buffering, reducing the probability of damage to the connecting rod group and further improving the quality of the connector.

[0078] In summary, the present application includes at least one of the following beneficial technical effects:

[0079] The test component is driven by the moving component to connect with the pin body. The test component first starts the power-on test to see if it is connected. If it is connected, it means that the pin body is installed and the position is correct. Then the test component continues to power on to perform a high-voltage test on the pin body. Products that fail the high-voltage test and are not connected during the power-on test are both unqualified products. The rejection mechanism is started to reject the unqualified connectors, thereby improving the quality of the connectors. BRIEF DESCRIPTION OF THE DRAWINGS

The two detection seats 81 are located on both sides of the conveying platform 21 and are installed on the frame 1 for sliding toward each other, so that the two detection seats 81 are close to or away from each other; the test assembly 82 is set on the two detection seats 81, and the two detection seats 81 are close to each other to drive the test assembly 82 to connect with the pin body. The test assembly 82 is first powered on to test whether it is connected. If it is connected, it means that the pin body is installed on the connector and the position is correct. Otherwise, if the power-on test is not connected, it means that the connector is unqualified. After the power-on test is connected, the test assembly 82 is powered on again for high-voltage testing. If the test is passed, it means that the connector is qualified, otherwise the connector is unqualified.

[0112] The moving assembly 83 is used to drive the two detection seats 81 to move, and the moving assembly 83 is two cylinders; the test assembly 82 includes two connecting rod groups 84, a control component and a high-voltage test machine 85, the two connecting rod groups 84 are respectively arranged on the two detection seats 81, and the connecting rod group 84 includes a plurality of connecting rod bodies arranged horizontally at intervals, and the plurality of connecting rod bodies are respectively arranged one-to-one corresponding to the plurality of pins on the pin body; the control component is fixedly installed on the frame 1 and controls the two connecting rod groups 84 to be powered on for testing, the high-voltage test machine 85 is fixedly installed on the frame 1 and is used for high-voltage testing, and the high-voltage test machine 85 is electrically connected to the control component.

[0113] When the two connecting rod groups 84 are powered on for testing and are interconnected, the control component controls the high-voltage tester 85 to power on the two connecting rod groups 84 for high-voltage testing, and the high-voltage tester 85 transmits the test results to the control component; if the test is not powered on, the product is unqualified, and the high-voltage tester 85 does not need to be started for testing.

[0114] The rejection mechanism 9 is electrically connected to the control component. When the control component receives the test failure signal, the control component controls the rejection mechanism 9 to start and reject the unqualified products. The rejection mechanism 9 includes a rejection plate 91 and a rejection plate 92, a driving component 93 and a collecting component 94. The rejection plate 91 and the rejection plate 92 are respectively located on both sides of the conveying platform 21 and are horizontally close to or away from the conveying platform 21. The lower surface of the rejection plate 91 is flush with the upper surface of the limit plate 13, and a rejection hole for the connector to pass through is provided on the limit plate 13 close to the side of the rejection plate 92. In the initial state, the rejection plate 92 is plugged and installed on the rejection hole to prevent the connector from falling. The driving component 93 is two cylinders, and the two cylinders are fixedly installed on the frame 1 and are used to drive the rejection plate 91 and the rejection plate 92 to move simultaneously. The two cylinders are electrically connected to the control component and are used to control the start and stop of the two cylinders. The collecting component 94 is used to collect unqualified and qualified connectors separately.

[0115] When the control component receives a signal of a defective product, the control component controls the two cylinders to start simultaneously, so that the rejection plate 1 91 is detached from the rejection hole, and the rejection plate 2 92 pushes the connector to fall from the rejection hole to the collection assembly 94 for collection, and then the two cylinders drive the rejection plate 2 92 and the rejection plate 1 91 back to their original positions, thereby achieving the removal of defective products.

[0117] The working principle of the embodiment of the present application is as follows:

[0118] The vibration plate loader 24 conveys the connector to the conveying table 21, and the conveyor belt drives multiple push blocks 23 to move. One push block 23 moves and pushes one connector to move, so that the connectors are distributed on the conveying table 21 and move at intervals. At the same time, the pin material strip moves driven by two conveying rollers 25, and the pin material strip moves to the cutting table 31 and the supporting table 51. The clamping cylinder 55 drives the clamping table 52 to move downward to clamp the pin body, and the sliding member 33 drives the cutting seat 35 to move downward to cut the pin material strip, and the sliding member 33 drives the cutting seat 35 to move upward.

[0119] The moving part 42 drives the pin body away from the cutting table 31, the moving part 44 drives the pin body to be plugged and installed on the connector, the clamping cylinder 55 is started to release the clamping of the pin body, the moving part 44 and the moving part 42 successively drive the supporting platform 51 and the clamping platform 52 back to their original positions, the connector and the pin body move to the re-push assembly 45 to continue pushing the pin body so that the pin body is installed in place, the connector moves to the bending mechanism 6, the driving part 63 drives the bending part 62 to move up and perform the first bend on the pin body, the driving part 63 drives the bending part 62 to move down, the driving part 66 drives the bending part 65 to continue to bend the pin body, and the driving part 66 drives the bending part 65 to move back, so as to complete the installation and bending of the pin body.

[0120] The connector and the pin body are moved to the detection device 8, and the driving component 93 drives the two connecting rod groups 84 to connect with the pin body. The control component is first energized to test whether it is energized. If it is energized, the control component controls the high-voltage tester 85 to perform a high-voltage test. If the test is not energized and the high-voltage test fails, it means that the connector is unqualified. Therefore, the connector is moved to the rejection mechanism 9, and the driving component 93 drives the rejection plate 1 91 and the rejection plate 2 92 to push the connector to fall into the collection tube 95 for collection, and the qualified connector is output through the output guide plate 96, so that the unqualified connector is rejected, thereby improving the quality of the connector.

[0121] Example 2

[0122] Reference Figure 1 , Figure 2 and Figure 7 The difference between this embodiment and the embodiment 1 is that two buffer assemblies 10 respectively connected to two connecting rod groups 84 are provided on the frame 1.

[0123] The buffer assembly 10 includes a fixed seat 101 and a fixed seat 102, a connecting piece 103, a connecting plate 104, an elastic piece 105 and a pressure sensor 106. The fixed seat 101 and the fixed seat 102 are fixedly installed on the frame 1 at intervals along a direction perpendicular to the length of the conveyor platform 21, and the fixed seat 102 is located on the side of the fixed seat 101 close to the conveyor platform 21; the connecting piece 103 is fixedly installed on the fixed seat 101 and is electrically connected to the control component, the connecting rod group 84 is slidably installed on the connecting piece 103 along a direction perpendicular to the length of the conveyor platform 21 and is slidably penetrated on the fixed seat 102, the connecting plate 104 is fixedly installed on the connecting rod group 84, the connecting plate 104 is located between the fixed seat 101 and the fixed seat 102, and the fixed seat 101, the fixed seat 102 and the connecting plate 104 are all made of insulating material.

[0124] There are multiple elastic members 105 and they are arranged one-to-one corresponding to the multiple connecting rod bodies. The elastic members 105 are sleeved on the connecting rod bodies and pressed against the fixing seat 101 and the connecting disk 104. The elastic members 105 make the connecting rod group 84 and the connecting disk 104 maintain a tendency to be close to the pin body and the conveying platform 21; the pressure sensor 106 is embedded in the side wall of the fixing seat 102 close to the fixing seat 101, and the elastic member 105 pushes the connecting disk 104 to press against the fixing seat 102 and the pressure sensor 106. The pressure sensor 106 is electrically connected to the control member, and the pressure sensor 106 transmits pressure data to the control member; when the pressure is less than the specified value, the connector is a defective product, and the control member controls the rejection mechanism 9 to reject the defective products.

[0125] After the pin body is pushed out of the connector during the bending process, the length of the pin body is longer, or the pin body is not bent properly during the bending process, which causes the bend of the pin body to protrude outward. In these two cases, both connecting rod groups 84 can be connected to the pin body and can be powered, but the actual position is wrong; the elastic member 105 is used to buffer the connecting rod group 84, and the pressure sensor 106 pressure value is used to control the rejection mechanism 9 to reject defective products, thereby further improving the detection effect.

[0126] The working principle of the embodiment of the present application is as follows:

[0127] When the pin body moves while being bent or the bent part of the pin body protrudes outward, the contact with the connecting rod group 84 will push the connecting rod group 84 to move, so that the connecting disk 104 is away from the pressure sensor 106, thereby reducing the pressure on the pressure sensor 106. Therefore, when the value of the pressure sensor 106 is less than the specified value, it indicates that the connector is a defective product. The control part controls the rejection mechanism 9 to reject the defective products, thereby further improving the quality of the connector.

[0128] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
