Description

Technical Field

[0001] The utility model relates to a multi-station automatic detection device for terminals of a new energy charging gun. Background Art

[0002] New energy charging gun terminals are common electrical connection components on current charging guns. Their structure is usually composed of a terminal block and a plug-in part connected to the terminal block via a shaft neck. The plug-in part is in the form of a split groove with a spring inside. At present, the production industry of new energy charging gun terminals requires the processed new energy charging gun terminals to be subjected to plug-in force testing, internal and external aperture testing of the plug-in part, and oiling processes in sequence. After testing, defective products are eliminated and good products are retained, thereby improving product quality.

[0003] Traditionally, the above-mentioned inspection processes are all completed manually with the help of simple clamping fixtures, but the disadvantages are obvious:

[0004] 1. Manual operation has high labor intensity, low efficiency and high labor costs, which increases the production costs of enterprises;

[0005] 2. There are large differences in operations between different personnel, and it is difficult to ensure consistency in test results and oiling effects, resulting in difficulty in ensuring product quality control;

[0006] 3. The production process may produce defective products due to the non-standard working techniques of different workers.

[0007] In order to improve the detection efficiency and ensure the detection quality of new energy charging gun terminals, the industry currently has designed corresponding professional automated detection stand-alone equipment for each process of new energy charging gun terminals, such as plug-in force testing devices, inner diameter visual inspection devices, outer diameter visual inspection devices and oiling devices. These devices are integrated and connected through a transmission mechanism to carry out continuous detection of new energy charging gun terminals.

[0008] However, the above-mentioned method of integrating the detection devices and then conducting the detection exposes the following problems in the actual implementation process:

[0009] 1. It is still necessary to manually clamp and replace the new energy charging gun terminals on each detection device, which hinders the improvement of detection efficiency; and because the orientation references of the new energy charging gun terminals on each detection device are different, workers are required to debug, which is time-consuming and laborious;

[0010] 2. Since the conveying mechanism and each detection device lack positioning or clamping fixtures for the new energy charging gun terminals with unified reference specifications, once the specification batch of the new energy charging gun terminals to be tested is changed (i.e., the line is changed), the conveying mechanism and the corresponding clamping fixtures of each detection device must also be replaced and debugged at the same time, which is costly and time-consuming.

[0011] 3. After multiple detection devices are integrated and connected, they will be large in size, and a special workshop is often required for them, which takes up more production resources of the enterprise. Summary of the invention

[0012] The purpose of the utility model is to provide a multi-station automatic detection device for new energy charging gun terminals which has a compact structure, high working efficiency and is easy to change lines for production.

[0013] The technical solution of the utility model is: a multi-station automatic detection device for terminals of a new energy charging gun, comprising a mounting platform and four detection stations arranged in parallel sequence thereon, wherein the head end and the tail end detection stations are respectively provided with an insertion and extraction force test device and an oiling device, while the two middle detection stations are respectively provided with an inner diameter visual detection device and an outer diameter visual detection device (the order of the two is arbitrary); it is characterized in that it also includes a terminal positioning tool and a terminal synchronous handling mechanism arranged on the mounting platform, the terminal positioning tool comprises six tooling units arranged side by side at equal intervals, which are a loading tooling unit and a unloading tooling unit respectively located at the head end and the tail end, and four detection tooling units located between the loading tooling unit and the unloading tooling unit, which are arranged one by one in correspondence with the insertion and extraction force test device, the inner diameter visual detection device, the outer diameter visual detection device and the oiling device; each tooling unit comprises a base and a terminal carrier detachably fixed thereon, and the terminal carrier is provided with a card slot for the new energy charging gun terminal to be embedded;

[0014] The terminal synchronous transport mechanism includes a swinging plate arranged on the guiding mechanism, on which are provided five pneumatic terminal clamps corresponding to the loading tooling unit and four inspection tooling units below, which are used to clamp the new energy charging gun terminals thereon. At the same time, the terminal synchronous transport mechanism also includes a swinging drive device, which is used to drive the swinging plate to swing back and forth along the guiding mechanism between the head end inspection station and the end end inspection station, so as to drive the pneumatic terminal clamps thereon to sequentially and synchronously transport the new energy charging gun terminals between adjacent tooling units (that is, the new energy charging gun terminals on the corresponding tooling units are sequentially and synchronously transported to the adjacent tooling units), and also includes a PLC controller, which is electrically connected to the insertion and extraction force testing device, the inner diameter visual inspection device, the outer diameter visual inspection device, the oiling device, the swinging drive device and the pneumatic terminal clamps.

[0015] Furthermore, the guiding mechanism described in the utility model includes a supporting plate and a transverse plate, the supporting plate is fixed on the mounting platform, the transverse plate is slidably assembled to the supporting plate by a horizontal linear guide rail, and the swing plate is slidably assembled to the transverse plate by a vertical linear guide rail; the swing drive device includes a forward and reverse motor, a reducer and an eccentric wheel, the output shaft of the forward and reverse motor is connected to the central axis of the eccentric wheel via the reducer, and the eccentric shaft of the eccentric wheel is connected to the swing plate, thereby driving the swing plate to swing back and forth along the guiding mechanism, and the forward and reverse motor is electrically connected to the PLC controller.

[0016] Furthermore, the loading fixture unit and the unloading fixture unit described in the utility model are both double-station fixture units, which include the base and the two terminal carriers detachably fixed thereon and arranged side by side, and also include a base transverse movement cylinder provided on the mounting platform and connected to drive the base to move transversely, which is used to switch the two terminal carriers on the base to the working position to cooperate with the corresponding pneumatic terminal clamps, and the base transverse movement cylinder is electrically connected to the PLC controller. The loading fixture unit and the unloading fixture unit are both designed as double-station fixture units, which can significantly improve the efficiency of loading and unloading; and it is more conducive to the execution speed of the terminal synchronous handling mechanism to be synchronized with the execution speed of the existing manipulator (that is, the loading and unloading of two new energy charging gun terminals can be completed at one time with the help of the manipulator in the same time), so as to avoid the speed of the manipulator loading and unloading at a single station not catching up with the execution speed of the synchronous handling mechanism.

[0017] In order to avoid the unloading fixture unit being too close to the detection fixture unit corresponding to the oiling device, thereby causing the detection fixture unit and the pneumatic terminal clamp above it to interfere with the unloading and grabbing action of the manual or mechanical hand on the unloading fixture unit, the following improvement measures are taken in the utility model:

[0018] Furthermore, the terminal positioning tooling described in the utility model includes seven tooling units arranged side by side at equal intervals, which are a loading tooling unit and a unloading tooling unit respectively located at the head end and the tail end, four inspection tooling units corresponding to the insertion and extraction force testing device, the inner diameter visual inspection device, the outer diameter visual inspection device and the oiling device located between the loading tooling unit and the unloading tooling unit, and a buffer tooling unit located between the unloading tooling unit and the inspection tooling unit corresponding to the oiling device, and the swing plate is provided with a pneumatic terminal clamp opposite to the buffer tooling unit.

[0019] The introduction of the buffer fixture unit increases the distance between the unloading fixture unit and the detection fixture unit corresponding to the oiling device, which can effectively prevent the detection fixture unit and the pneumatic terminal clamps thereon from interfering with the unloading and grabbing actions of manual or robotic arms on the unloading fixture unit.

[0020] Furthermore, the tooling unit in the utility model also includes an infrared sensor device arranged on the terminal carrier for detecting whether there is a new energy charging gun terminal in the card slot, and the infrared sensor device is electrically connected to the PLC controller.

[0021] Furthermore, the new energy charging gun terminal in the utility model includes a terminal block and a plug-in portion connected to the terminal block via a shaft neck portion, and a blocking piece is formed in the slot and extends into the outer ring groove of the shaft neck portion to limit the axial movement of the new energy charging gun terminal along the slot.

[0022] Furthermore, the terminal carrier in the utility model is bonded with a magnetic sheet at the bottom, and is fixed to the base by adsorption of the magnetic sheet. The terminal carrier in the utility model is actually made of a polymer material, and the base is made of an iron-carbon alloy. Alternatively, the terminal carrier can also be fixed to the base by screws. The above two positioning methods of the terminal carrier are convenient for quickly replacing the terminal carrier to adapt to the line change detection of new energy charging gun terminals of different specifications.

[0023] Furthermore, the bottom of the terminal carrier in the utility model is provided with a plurality of positioning holes, and the base is provided with positioning protruding columns that cooperate with the positioning holes.

[0024] Furthermore, the swing plate in the utility model is also provided with four terminal clamping cylinders, which are respectively arranged in one-to-one correspondence with the four detection fixture units corresponding to the insertion and extraction force testing device, the inner diameter visual detection device, the outer diameter visual detection device and the oiling device, and are used to clamp the terminals of the new energy charging gun into the card slots of the terminal carriers, and the four terminal clamping cylinders are electrically connected to the PLC controller. When the swing plate moves, the four terminal clamping cylinders swing back and forth synchronously with the swing plate.

[0025] The working principle of the utility model is as follows:

[0026] In the actual implementation process of the present utility model, manual or robotic arms are used to grab the new energy charging gun terminals to be tested from the tray to be tested and place them on the loading tooling unit. The unloading can also be done by manual or robotic arms to remove the new energy charging gun terminals that have been tested on the unloading tooling unit and then send them to the good product tray or the defective product tray.

[0027] During specific operation, under the control of the PLC controller, the swing drive device drives the swing plate to swing back and forth along the guide mechanism between the head-end inspection station and the end-end inspection station, driving the pneumatic terminal clamps on it to sequentially and synchronously transport the new energy charging gun terminals between adjacent tooling units; the new energy charging gun terminals on the loading tooling unit are transported in sequence and positioned by the terminal clamping cylinder to the corresponding inspection tooling units in front of the plug-in force test device, inner diameter visual inspection device, outer diameter visual inspection device and oiling device, and the corresponding devices are started to perform the plug-in force test, inner diameter inspection, outer diameter inspection and oiling operations in sequence.

[0028] Similar to the known technology, the test results of the plug-in force test device, the inner diameter visual inspection device, and the outer diameter visual inspection device are sent to the PLC controller in the form of a pulse signal (NG signal is sent if the test is qualified, and OK signal is sent if the test is unqualified). As long as any one of the tests fails, the PLC controller can determine that the new energy charging gun terminal is a defective product, thereby sending a control signal to the connected manipulator, or sending a prompt message to the manual to remove the defective product from the unloading tooling unit and transfer it to the defective product tray. Only when the above three test results of the new energy charging gun terminal are OK can it be determined as a good product, so that it can be removed from the unloading tooling unit and transferred to the good product tray.

[0029] The PLC controller is connected to the infrared sensor device. When the infrared sensor device on the terminal carrier of a certain tooling unit detects that there is no new energy charging gun terminal in its card slot, it sends a signal to the PLC controller to record the empty detection information to avoid generating erroneous measurement data.

[0030] Of course, the PLC controller can also be connected to an external server or cloud storage device to store and share the detection data of the new energy charging gun terminal with the terminal device.

[0031] Compared with the prior art, the multi-station automatic detection device for new energy charging gun terminals provided by the utility model has the following beneficial effects:

[0032] 1. The utility model can replace manual work to complete the synchronous automatic transfer and clamping positioning of the new energy charging gun terminals between various inspection stations, and has a short transportation path and fast execution speed. It can greatly save the inspection time of the new energy charging gun terminals and improve the inspection efficiency. At the same time, it reduces the labor intensity of workers and saves labor costs for the enterprise.

[0033] 2. The utility model adopts tooling units of exactly the same specifications to position the new energy charging gun terminals. The terminal carrier thereon can be quickly replaced relative to the base, which is convenient for adapting to the line change detection of new energy charging gun terminals of different specifications. There is no need to replace or modify any other mechanism for line change, thus avoiding re-debugging, greatly saving the line change cost and greatly improving the line change efficiency.

[0034] 3. The overall layout of the utility model is compact and occupies a small volume. Compared with the current multi-detection device integrated connection equipment, it does not need to occupy a large factory space, can save layout, and save enterprise production resources.

[0035] 4. The execution action of the utility model has high precision, good consistency, higher operating stability and reliability, ensuring that the detection of new energy charging gun terminals in the same batch has consistent high quality control.

The fixing method of the terminal carrier 602 and the base 601 is the same as that of the single-station fixture unit mentioned above and will not be repeated. Similarly, the two terminal carriers 602 of the double-station fixture unit are provided with infrared sensors 604 for detecting whether there is a new energy charging gun terminal 7 in the corresponding slot 602a, and these infrared sensors 604 are also electrically connected to the PLC controller.

[0057] Combine again Figure 1 and Figure 2 As shown, the guiding mechanism in this embodiment includes a supporting plate 10 and a transverse plate 11, the supporting plate 10 is fixed on the mounting platform 1, the transverse plate 11 is slidably assembled to the supporting plate 10 through a horizontal linear guide 12, and the swing plate 8 is slidably assembled to the transverse plate 11 through a vertical linear guide 13; the swing drive device includes a forward and reverse motor 14, a reducer 15 and an eccentric wheel 16, the output shaft of the forward and reverse motor 14 is connected to the central axis of the eccentric wheel 16 via the reducer 15, and the eccentric shaft of the eccentric wheel 16 is connected to the swing plate 8, so as to drive the swing plate 8 to swing back and forth along the guiding mechanism, and the forward and reverse motor 14 is electrically connected to the PLC controller.

The four terminal clamping cylinders 17 are all electrically connected to the PLC controller.

[0059] The working principle of the utility model is as follows:

[0060] In the actual implementation process of the present utility model, manual or robotic arms are used to grab the new energy charging gun terminal 7 to be tested from the tray to be tested and place it on the loading tooling unit 6A. The unloading can also be done by manual or robotic arms to remove the new energy charging gun terminal 7 that has been tested on the unloading tooling unit 6B and then send it to the good product tray or the defective product tray.

[0061] During specific operation, under the control of the PLC controller, the swing drive device drives the swing plate 8 to swing back and forth along the guide mechanism between the head end detection station and the end end detection station, driving the pneumatic terminal clamps 9 thereon to sequentially and synchronously transport the new energy charging gun terminals 7 between adjacent tooling units 6; the new energy charging gun terminals 7 on the loading tooling unit 6A are transported in sequence and positioned to the detection tooling unit 6C corresponding to the plug-in force test device 2, the inner diameter visual inspection device 3, the outer diameter visual inspection device 4 and the oiling device 5 in front by the terminal clamping cylinder 17, and the corresponding devices are started to perform the plug-in force test, inner diameter detection, outer diameter detection and oiling operations in sequence.

As long as any one of the tests fails, the PLC controller can determine that the new energy charging gun terminal 7 is a defective product, thereby sending a control signal to the connected manipulator, or sending a prompt message to the manual to remove the defective product from the unloading tooling unit 6B and transfer it to the defective product tray. Only when the above three test results of the new energy charging gun terminal 7 are OK can it be determined as a good product, so that it can be removed from the unloading tooling unit 6B and transferred to the good product tray.

[0063] The PLC controller is connected to the infrared sensor device 604. When the infrared sensor device 604 on the terminal carrier 602 of a certain tooling unit 6 detects that there is no new energy charging gun terminal 7 in its card slot 602a, it sends a signal to the PLC controller to record the empty detection information to avoid generating erroneous measurement data.
