[0003] The main purpose of the utility model is to provide a device for automatically sorting crimping terminals, aiming to replace manual identification, reduce the loss of human resources, improve the accuracy of detection, and improve the overall production efficiency.

[0004] In order to achieve the above-mentioned purpose, the utility model proposes a device for automatically sorting crimping terminals, comprising:

[0005] The transport device comprises a transport part, wherein the transport part has a feed end and at least two discharge ends, and is used for the crimping terminal to enter from the feed end and leave from one of the discharge ends;

[0006] A detection device, comprising an image recognizer arranged above the transport part, and a control circuit board electrically connected to the image recognizer, wherein the image recognizer is used to detect the wire terminals passing through the transport part and below the wire terminals, and to generate a recognition signal and transmit it to the control circuit board; and

[0007] The sorting device includes a pushing member close to the discharge end and arranged on both sides of the transport part. The pushing member is electrically connected to the control circuit board and is used to receive a pushing signal from the control circuit board to push the wire crimping terminal to a discharge end of the transport part.

[0008] In one embodiment, the transport device further comprises a driving member, and the driving member is used to drive the transport part to move cyclically.

[0009] In one embodiment, the transport device further comprises two material receiving boxes, and the material receiving boxes are arranged in one-to-one correspondence with the discharge end of the transport part, so as to receive the crimping terminals leaving from the discharge end of the transport part.

[0010] In one embodiment, the transport device further comprises a guide trough body installed at two discharge ends of the transport part, and the two guide trough bodies gradually separate in a direction away from the transport part.

[0011] In one embodiment, the detection device also includes an in-place detector electrically connected to the control circuit board. The in-place detector is installed on one side of the transport part corresponding to the position below the image identifier, and is used to detect the wire crimping terminal transported to the bottom of the image identifier via the transport part, and transmit an in-place signal to the control circuit board, so that the image identifier is controlled by the control circuit board to identify the wire crimping terminal on the transport part.

[0012] In one embodiment, the detection device further includes a protective cover, which is erected above the transport portion, and the image recognizer is installed on the protective cover.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture.

In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0029] like Figure 1 As shown, the utility model proposes an automatic sorting device 100 for crimping terminals, comprising a transport device 1, a detection device 2, and a sorting device 3. The transport device 1 comprises a transport part 11, the transport part 11 has a feed end 111, and at least two discharge ends 112, for the crimping terminals to enter from the feed end 111 and leave from one of the discharge ends 112; the detection device 2 comprises an image recognizer 21 arranged above the transport part 11, and a control circuit board electrically connected to the image recognizer 21, the image recognizer 21 is used to detect the crimping terminals flowing through the transport part 11 and passing through the bottom thereof, and generating a recognition signal to transmit to the control circuit board; and,

[0030] The sorting device 3 includes a pusher 31 close to the discharge end 112 and disposed on both sides of the transport portion 11. The pusher 31 is electrically connected to the control circuit board and is used to receive a push signal from the control circuit board to push the crimping terminal to the discharge end 112 of the transport portion 11.

[0031] The technical solution of the utility model transports the crimping terminals through the transport part 11. During the transportation process, the crimping terminals pass through the image recognizer 21 arranged above the transport part 11. The image recognizer 21 takes pictures of the area where the crimping terminals need to be inspected, and generates an identification signal to transmit to the control circuit board. The control circuit board controls the operation of the pusher 31 based on the identification signal, so that the crimping terminals that pass the inspection leave from the discharge end 112 of one transport part 11, and the crimping terminals that fail the inspection leave from the discharge end 112 of the other transport part 11. Through the seamless connection of the three steps of transportation, inspection and sorting, the automatic sorting of the crimping terminals is realized, which greatly improves the production efficiency and accuracy, and reduces the errors and costs caused by manual operation.

[0032] It is understandable that the target image is collected by the image recognizer 21, and the recognition signal is generated and transmitted to the control circuit board. The control circuit board performs grayscale processing on the collected sample image and target image, and then performs denoising through median filtering to make it adaptable to subsequent processing. The denoised image is first subjected to edge detection by Hough change and Canny algorithm to find the edges of the regular product to be detected, and then a series of operations such as rotation, scaling, and cropping are performed to match the target image and the sample image. Finally, the two images are subjected to difference operation and opening operation to obtain the difference image and defect value. When the defect value exceeds the threshold, it is defective, otherwise it is non-defective. Non-defective products are qualified products, and defective products are unqualified products.

[0033] In one embodiment, the transport device 1 further comprises a driving member, and the driving member is used to drive the transport part 11 to move cyclically.

[0034] It can be understood that due to the presence of the driving member, the transport part 11 can achieve continuous cyclic movement, which means that the crimping terminal can be continuously transported from the feed end 111 to each discharge end 112 along a set path without human intervention, thereby ensuring the continuity and high efficiency of the production process.

[0035] The following is an explanation of the structure that can be used for the driving member, and the driving member can use a motor as the driving force. The motor can be a DC motor, an AC motor, a servo motor, or a stepper motor. Each motor has its own characteristics and applicable scenarios, and no special restrictions are made here. The power generated by the motor is transmitted to the transport part 11 through a transmission mechanism. Common transmission mechanisms include gear transmission, belt transmission, chain transmission, and screw nut transmission. The choice of which transmission method depends on the required torque, speed, accuracy, and space constraints, and no special restrictions are made here.

[0036] In one embodiment, the transport device 1 further includes two receiving boxes 12 , which are arranged one-to-one corresponding to the discharge end 112 of the transport portion 11 to receive the crimping terminals leaving the discharge end 112 of the transport portion 11 .

[0037] It can be understood that the receiving box 12 is arranged in a one-to-one correspondence with the discharge end 112 of the transport part 11, so that each receiving box 12 only receives the wire terminals from a specific discharge end 112, thereby automatically receiving qualified wire terminals and unqualified wire terminals that have been sorted without manual intervention, which greatly improves the collection efficiency and reduces labor costs.

[0038] In one embodiment, the transport device 1 further includes a guide trough body 13 installed at two discharge ends 112 of the transport portion 11 , and the two guide trough bodies 13 gradually separate in a direction away from the transport portion 11 .

[0039] It is understandable that, since the guide troughs 13 gradually separate as they move away from the discharge end 112, they can guide the material to disperse in a wider space, thereby reducing the accumulation of material in a particular area. This helps to maintain the smoothness of the transportation system and avoid blockages and downtime.

[0040] In one embodiment, the detection device 2 also includes an in-place detector 22 electrically connected to the control circuit board. The in-place detector 22 is installed on one side of the transport part 11 corresponding to the position below the image identifier 21, and is used to detect the wire crimping terminal transported to the bottom of the image identifier 21 via the transport part 11, and transmit an in-place signal to the control circuit board, so that the image identifier 21 is controlled by the control circuit board to identify the wire crimping terminal on the transport part 11.

[0041] It can be understood that when the crimping terminal located on the transport part 11 is transported to the bottom of the in-place detector 22, the in-place detector 22 detects the crimping terminal, and the in-place detector 22 generates an in-place signal and transmits it to the control circuit board. The control circuit board controls the sorting part to work according to the received signal to adjust the corresponding crimping terminal to leave the corresponding discharge end 112.

[0042] The following is an explanation of the structure that can be adopted by the in-place detector 22. The in-place detector 22 can adopt a photoelectric sensor (which determines the position of an object by emitting a light beam and detecting changes in reflected or transmitted light) and a proximity switch (which uses the principle of electromagnetic induction or capacitance change to change its magnetic field or electric field when an object approaches, thereby triggering a switch action. Common ones include inductive proximity switches and capacitive proximity switches), and a magnetic sensor (which determines the position of a magnetic object by detecting changes in the magnetic field, and is often used to detect the position of metal objects). The selection can be made according to actual industrial production needs, and no special restrictions are made here.

[0043] In one embodiment, the detection device 2 further includes a protective cover 23 . The protective cover 23 is erected above the transport portion 11 , and the image recognizer 21 is installed on the protective cover 23 .

[0044] It is understandable that the protective cover 23 can provide physical protection for the image recognizer 21, prevent the intrusion of pollutants such as dust, water vapor, and oil, avoid these factors affecting the normal operation of the image recognizer 21, and extend the life of the device. At the same time, the protective cover 23 can create a relatively closed and stable environment, reduce external light interference, ensure that the image recognizer 21 works under consistent lighting conditions, and improve the accuracy and consistency of image recognition.

[0045] In one embodiment, the detection device 2 further includes a light emitting member 24 , which is disposed above the transport portion 11 corresponding to the position of the image identifier 21 , and the light emitting member 24 is used to emit light to illuminate the crimping terminals passing thereunder.

[0046] It can be understood that the light provided by the light-emitting element 24 can eliminate shadows and reflections. Stable and uniform lighting is conducive to the image recognition algorithm to more accurately analyze the size, color, and shape characteristics of the crimping terminals, improve image contrast, and enable the image recognizer 21 to capture clear, high-quality images, thereby improving the accuracy and consistency of sorting.

[0047] In one embodiment, the pusher 31 is a cylinder 311 that can release compressed gas in a specific flow direction to push the crimping terminal located on the transport part 11 so that the crimping terminal changes to the discharge end 112 of another transport part 11 and leaves.

[0048] It is understandable that by precisely controlling the flow direction and pressure of the compressed gas in the cylinder 311, the crimping terminal can be pushed accurately to ensure its stability and accuracy during transportation. In addition, the use of the cylinder 311 can also provide sufficient force to overcome friction and other resistances, ensuring that the crimping terminal can move smoothly on the transport part 11, thereby changing the discharge end 112 and improving automation.

[0049] In one embodiment, the two cylinders 311 are staggered in the transport direction of the vertical transport part 11 so that the gases with pressures in specific flow directions released by the two cylinders 311 do not interfere with each other.

[0050] It is understandable that since the gases released by the two cylinders 311 have specific flow directions and pressures, if they are directly aligned, the airflow released by one cylinder 311 may interfere with the operation of the other cylinder 311, resulting in unstable airflow, uneven thrust, direction deviation or even unexpected force, thereby affecting the precise movement of the crimping terminal. The staggered setting can ensure that the airflow released by each cylinder 311 is relatively independent in space and does not interfere with each other, thereby improving the stability and accuracy of the pushing process. At the same time, the staggered setting can arrange the cylinders 311 more reasonably in a limited space to avoid the equipment being too compact and affecting operation and maintenance.

[0051] In one embodiment, the pushing member 31 includes a pushing portion, which can move in a transport direction perpendicular to the transport portion 11 to push the crimping terminal on the transport portion 11 .

[0052] It is understandable that the moving ability of the push part can be realized by the cylinder 311 and the electric push rod. These power sources can accurately control the moving speed, distance and force of the push part according to the instructions of the control system to adapt to the wire terminals of different specifications and weights. By accurately controlling the movement of the push part in the vertical direction, it can be ensured that the wire terminal can accurately move along the preset path when being pushed, avoiding the wire terminal from leaving the wrong discharge end 112 due to the deviation of the pushing direction, thereby improving the measurement accuracy of the product.

[0053] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
