Description

Technical Field

[0001] The invention relates to the technical field of connector pin processing, and in particular to a device for processing automobile connector pins. Background Art

[0002] The automotive connector is a common electronic device in automotive electronic equipment, generally consisting of four parts: contact, shell, insulator and surrounding parts.

[0003] The contact piece is generally a metal pin, and during installation, the pin needs to be inserted into the hole of the housing, and a certain depth needs to be ensured. For this reason, the application number "201510367321.X" discloses a device for ensuring the position of the pin of an automobile connector, which mainly uses a cylinder to push a pressing plate to press the pin into the hole to a specified depth. However, in the actual application process, there is a certain friction resistance between the part of the pin in the hole and the inner wall of the hole, and the pin is very easy to bend. Therefore, when the pressing plate pushes the pin, it will not push the pin to move at the first time, but will cause the pin to deform and bend to a certain extent, and then overcome the friction resistance to push the pin to move inside the hole. When the pressing plate leaves, the pin recovers under the action of its own elasticity. Therefore, the distance that the cylinder controls the pressing plate to move is slightly less than the actual moving distance of the pin, that is, the depth of the pin inserted into the hole is insufficient and the exposed part is longer, so it is easy to mismatch in the subsequent installation process.

[0004] In view of this, the present application provides a device for processing pins of automobile connectors. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a device for processing pins of automobile connectors.

[0015] The present invention has the following beneficial effects:

[0016] 1.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-5 A device for processing pins of automobile connectors comprises a workbench 1, on which a limiting seat 6 is fixedly provided, a side wall of the limiting seat 6 is provided with a receiving groove 3, two limiting plates 5 are embedded in the receiving groove 3, a push-pull cylinder 2 is installed on the workbench 1, a lifting groove 20 is provided at the upper end of the workbench 1, a lifting cylinder 21 is installed in the lifting groove 20, and a support plate 22 is fixedly connected to the telescopic end of the lifting cylinder 21.

[0026] Reference Figure 3 The telescopic end of the push-pull cylinder 2 is fixedly connected with a conical plate 8, and a guide groove 9 is opened on the side wall of the conical plate 8. A nut 13 is slidably connected in the guide groove 9, and a screw 10 threadedly connected to the nut 13 is rotatably connected in the guide groove 9, and a push rod 11 is fixedly connected to the side wall of the nut 13, and the end of the push rod 11 away from the nut 13 is fixedly connected with a first magnetic plate 12, a second magnetic plate 4 is embedded in the accommodating groove 3, and the first magnetic plate 12 and the second magnetic plate 4 have opposite magnetic poles, and a driving groove 14 is opened on the side wall of the conical plate 8, and a driving mechanism for driving the screw 10 to rotate is installed in the driving groove 14.

[0027] Reference Figure 3 The driving mechanism includes a gear 17 rotatably connected to the driving groove 14, and the screw 10 extends into the driving groove 14 and is fixedly connected to the side wall of the gear 17. A spring 15 is fixedly connected to the top of the driving groove 14, and a rack 16 meshing with the gear 17 is fixedly connected to the lower end of the spring 15. The conical plate 8 is made of silicon steel material, and an iron bar 18 is fixedly connected to the lower end of the rack 16. An electromagnet 19 is installed at the bottom of the driving groove 14. It should be noted that the conical plate 8 is made of silicon steel material, which can shield and isolate the magnetic fields of the external first magnetic plate 12 and the second magnetic plate 4, and can prevent the magnetic fields of the first magnetic plate 12 and the second magnetic plate 4 from affecting the internal electromagnet 19 and the iron bar 18.

[0028] A conductive plate 23 is fixedly provided on the side wall of the first magnetic plate 12, a telescopic bellows 25 is fixedly connected to the side wall of the second magnetic plate 4, and a conductive contact rod 24 is fixedly connected to one end of the telescopic bellows 25 away from the second magnetic plate 4, and the conductive plate 23 and the conductive contact rod 24 are electrically connected to the electromagnet 19 through a control circuit. It should be noted that a magnetic field with horizontal magnetic lines of force will be generated between the first magnetic plate 12 and the second magnetic plate 4. When the pin 702 is bent and deformed, it will be displaced in the vertical direction and interact with the magnetic lines of force of the magnetic field, thereby generating an induced current. At the same time, the conductive plate 23 and the conductive contact rod 24 are in contact with the pin 702 to form a closed loop. The generated induced current will be transmitted to the control circuit along this closed loop in the form of an electrical signal. After receiving the current signal, the control circuit will allow the electromagnet 19 to pass a corresponding current in a certain proportion according to the size of the current signal, and generate a magnetic force of a corresponding magnitude, so that the elastic force of the spring 15 can be overcome, and the iron bar 18 and the rack 16 can be attracted to move down a corresponding distance, thereby pushing the gear 17 and the screw 10 to rotate a certain number of turns, and the nut 13 and the push rod 11 can be moved outward a corresponding distance, thereby pushing the first magnetic plate 12 to continue to move right for a certain distance.

[0029] The side wall of the limiting seat 6 is fixedly connected with a hanging plate 36, the lower end of the hanging plate 36 is fixedly connected with an extrusion cylinder 32, the telescopic end of the extrusion cylinder 32 is fixedly connected with a flat head plate 33, the lower end of the flat head plate 33 is fixedly provided with a rubber cover 34, and an electric vibration plate 35 is provided in the rubber cover 34, and the upper end of the electric vibration plate 35 is fixedly connected to the lower end of the flat head plate 33.

[0030] Reference Figure 2 A pneumatic cavity 27 is provided on the side wall of the limit seat 6, a push plate 28 is sealed and slidably connected in the pneumatic cavity 27, a conductive touch plate 29 is embedded in the side wall of the push plate 28, a conductive strip 30 is embedded on the inner wall of the pneumatic cavity 27, the conductive touch plate 29 is electrically connected to the control circuit, the conductive strip 30 is electrically connected to the electric vibration sheet 35, a vent hole 31 is provided on the inner wall of the pneumatic cavity 27, and the pneumatic cavity 27 is communicated with the telescopic bellows 25 through the air pipe 26. Specifically, by setting the electric vibration piece 35, the conductive touch plate 29 and the conductive strip 30, when the pin 702 is pushed into the hole groove 701 to a specified depth position, the pin 702 will also push the conductive contact rod 24 to move rightward and contract the telescopic bellows 25, thereby squeezing the air in the telescopic bellows 25 into the pneumatic cavity 27 through the air pipe 26, thereby pushing the push plate 28 to move leftward, so that the conductive touch plate 29 will contact the conductive strip 30. At this time, the current output by the control circuit will be input to the electric vibration piece 35 through the conductive touch plate 29 and the conductive strip 30, so that the electric vibration piece 35 is energized to generate vibration, and the magnitude of the current passed through the electric vibration piece 35 is controlled by the magnitude of the current signal received by the control circuit.

[0031] When using the device, the shell 7 to be processed is clamped in the receiving groove 3, and the pin 702 to be inserted is placed in the corresponding hole groove 701. Then the push-pull cylinder 2 is started to push the conical plate 8 and the first magnetic plate 12 to the right, so that the first magnetic plate 12 can push the pin 702 into the hole groove 701 in the shell 7. At this time, the pin 702 will bend and deform to a certain extent, such as Figure 2 Pin 702 is shown as a dotted line.

[0032] Since the magnetic poles of the first magnetic plate 12 and the second magnetic plate 4 are horizontally distributed and the magnetic poles of the two opposite names are opposite, the following force will be generated between the first magnetic plate 12 and the second magnetic plate 4: Figure 2 Therefore, when the pin 702 moves horizontally, its movement direction is parallel to the magnetic lines, and no induced current is generated. When the pin 702 is deformed and bent, its bent part moves vertically upward and can interact with the horizontal magnetic lines, thus generating an induced current. The greater the bending amplitude, the longer the movement distance, and thus the greater the intensity of the induced current.

[0033] When the pin 702 bends and cuts the magnetic field line, the current signal generated will be output to the control circuit, and the control circuit will make the electromagnet 19 pass different currents according to the strength of the current signal. Figure 3 , and the electromagnet 19 can attract the iron bar 18 to move downward after being energized, and the iron bar 18 drives the rack 16 to move downward synchronously, so that the gear 17 can rotate forward, so that the screw 10 can rotate synchronously, and the nut 13 on the screw 10 can move rightward, and the nut 13 can push the first magnetic plate 12 to move rightward horizontally through the push rod 11, thereby continuing to push the pin 702 to move rightward for a distance. In this way, the pin 702 that has been bent and deformed can be compensated for displacement, so that the pin 702 can be inserted into the specified position in the hole slot 701.

[0034] It can be seen from the above that the compensation displacement distance of the pin 702 is positively correlated with the amplitude of its bending. Therefore, by adjusting parameters such as the pitch of the nut 13 and the screw 10, the pin 702 can be inserted into the hole 701 at an accurate position, thereby ensuring the position accuracy of the pin 702.

[0035] Reference Figure 1 and Figure 5 Furthermore, when the pin 702 is inserted into the designated position in the hole groove 701, the lifting cylinder 21 lifts the support plate 22 upward and supports the exposed lower end of the pin 702. At the same time, the squeezing cylinder 32 pushes the flat head plate 33 downward, so that the lower end of the rubber cover 34 contacts the upper end surface of the pin 702. After that, the control circuit can pass different currents into the electric vibration sheet 35 according to the size of the received current signal. The electric vibration sheet 35 will generate vibrations of different intensities according to the bending amplitude of the pin 702, and act on the pin 702 through the rubber cover 34, so as to squeeze and flatten the pin 702, which can help the deformed pin 702 to recover quickly, and also prevent some pins 702 from being unable to recover by their own elasticity due to excessive deformation.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
