Description

Technical Field

[0001] The present invention relates to the technical field of sensor pin positioning, and in particular to a wireless intelligent sensor pin positioning device. Background Art

[0002] As a tool for humans to obtain information, sensors are an important part of modern information technology. Traditionally, the output of sensors is mostly analog signals, which do not have signal processing and networking functions themselves. They need to be connected to specific measuring instruments to complete signal processing and transmission functions. Intelligent sensors can perform processing on the original data internally, can exchange data with the outside world through standard interfaces, and can change the operation of the sensors through software control according to actual needs, so as to achieve intelligence and networking. The emergence of intelligent sensors has changed the design concept, production mode and application mode of traditional sensors, and is considered to be one of the important technologies affecting human future life.

[0003] With the development of society, new requirements have been put forward for sensor systems in many fields of people's production and life. The precise and efficient welding of sensor pins is also a continuous breakthrough in production and processing. The pins of intelligent sensors are used to lead out the internal circuit of the sensor and serve as an interface for connecting the peripheral circuit, and are fixed outside the integrated chip by welding. The accuracy of the positioning and docking of intelligent sensors and pins is an important condition affecting the welding qualification rate. The patent with the publication number CN113492285B discloses a sensor pin welding device that can self-position the welding position with high precision. This patent sets a rotatable welding platform, and installs a clamping component on the welding platform to limit and clamp the sensor, and uses a first driving component to control the welding head to accurately dock it to the docking position of the sensor and the pin. Although this disclosed technology has many beneficial effects, it lacks a docking method for the sensor and the pin.

[0004] In production, the sensor and the pin are independent components, and form an integral whole after positioning, docking and welding. However, the pins are generally made of copper pins, tinned copper-clad steel wires, etc. and have a small structure. In an automated production platform, the clamping part needs to re-clamp one or a group of pins each time for positioning and docking with the sensor, and needs to perform multiple angle adjustments to complete the docking, which is an important factor causing the difficulty in improving the welding qualification rate. We hope to get rid of the steps of pin picking, placing and clamping, and can quickly position with the sensor under single-dimensional adjustment to achieve precise docking and improve the welding qualification rate. Therefore, it is very necessary to design a wireless intelligent sensor pin positioning device. Summary of the Invention

[0005] The purpose of the present invention is to propose a wireless intelligent sensor pin positioning device to solve the problems mentioned in the above background art.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A pin positioning device for a wireless intelligent sensor includes a workbench for docking pins with the sensor, and further includes a fixing fixture and a positioning tooling provided on the workbench. The pins pass through the positioning tooling and are clamped by it. The positioning tooling is provided with a conveying mechanism for conveying the pins and a cutting mechanism for cutting the pins; the fixing fixture for fixing the sensor can pass through from one side of the positioning tooling for docking with the pins. In the present invention, the pins are initially in an uncut state. After being welded to the sensor, they are trimmed and cut. The cut pins are welded to the sensor to form a whole, and the remaining pins are moved close to the next sensor again, thereby accelerating the positioning and welding speed of the sensor and the pins. Secondly, in the present invention, the pins always move horizontally and reversely in a single direction, and the sensor moves unidirectionally perpendicular to it, reducing the problem of multi-angle adjustment during positioning and achieving simpler and more accurate results.

In the present invention, a conveying mechanism and a cutting mechanism are arranged around the pins in the positioning tooling. After each pin is welded to the sensor, the pin is cut to separate the length of the pin required by the sensor, and after each cutting, the conveying mechanism is used to re-control the remaining pins to approach the next sensor. By maintaining horizontal and unidirectional movement, the docking accuracy and efficiency with the sensor can be provided.

[0013] Preferably, the chute frame includes a first chute and a second chute. The second chute is connected to the second fixing table through a first elastic member. The second chute replaces a part of the first chute and is slidably engaged with it.

The cylinder is installed on the second fixing table to drive the blade to approach the pins, and the drawer is installed on the second fixing table. In the present invention, a chute frame is provided for the pins to pass through the second fixing table of the positioning tooling. The chute frame is divided into two parts, namely a first chute and a second chute, and the first chute and the second chute are slidably engaged. The second chute is arranged at the position of the cutting mechanism and is separated from the first chute when cutting the pins. The elastically arranged second chute fills the gap of the first chute and avoids the influence of the blade.

[0016] Preferably, it further includes a jetting assembly. The jetting assembly includes a jetting pipe installed inside the second fixing table. A jetting branch pipe with a plurality of nozzles distributed therein passes through the inside of the jetting pipe.

The positioning tooling is used to clamp the entire uncut copper bar as a pin and slide unidirectionally on the workbench. The fixing fixture is used to clamp the sensor and slide unidirectionally on the workbench.

[0035] Embodiment 1:

[0036] Please refer to Figure 1-2A wireless intelligent sensor pin positioning device includes a workbench 800 for docking a pin 100 with a sensor 200, and also includes a fixing fixture 300 and a positioning tool 400 arranged on the workbench 800. The pin 100 passes through the positioning tool 400 and is clamped by it. The positioning tool 400 is provided with a conveying mechanism 500 for conveying the pin 100 and a cutting mechanism 600 for cutting the pin 100; the fixing fixture 300 for fixing the sensor 200 can pass through one side of the positioning tool 400 for docking with the pin 100.

[0037] Some implementation methods of the present application are described in detail below with reference to the accompanying drawings:

[0038] See also Figure 1-2 The present application is used for positioning and docking of a wireless intelligent sensor 200 and a pin 100, so as to achieve the purpose of fast docking and precise welding. Two cross slides are vertically arranged on a workbench 800 for positioning and docking, wherein a fixing fixture 300 is slidably placed in one of the slides, and a positioning tool 400 is slidably placed in the other slide. The fixing fixture 300 is used to clamp the sensor 200 so that it is fixed in the center, so as to achieve uniform and precise positioning each time. The positioning tool 400 is used to clamp the entire uncut and segmented pin 100. After one end of the pin 100 passes through the positioning tool 400 to complete the positioning welding with the sensor 200, it is cut to improve the efficiency of positioning and docking.

[0039] The pin 100 is a copper strip.

[0040] In some embodiments, two positioning tools 400 are symmetrically arranged around the fixing fixture 300 and respectively clamp the pins 100 for double-sided welding of the pins 100 of the sensor 200. A plurality of fixing fixtures 300 are equidistantly distributed in the same slide groove and move synchronously. Each fixing fixture 300 clamps a sensor 200, forming a docking process like an assembly line, thereby accelerating the efficiency of docking and positioning.

[0041] In some embodiments, a positioning fixture 400 is installed on the pin 100 in the slide slot for single-sided welding of the pin 100 of the sensor 200, and a plurality of fixing fixtures 300 are arranged to be equidistantly distributed in the same slide slot and move synchronously.

[0042] During the implementation process, the fixing fixture 300 is first moved to the intersection of the slide groove, and then one or two positioning tools 400 are driven to approach the sensor 200 until the pin 100 contacts the sensor 200. In this process, the positioning tool 400 will be connected to the fixing fixture 300 through the jet assembly 700, and the positioning tool 400 is driven to rotate. The positioning tool 400 and the fixing fixture 300 rotate synchronously to achieve multi-sided welding of the pin 100 and the sensor 200.

[0043] See alsoFigures 3-7 In the present application, the fixing fixture 300 for clamping and fixing the sensor 200 includes a first base 301, a first fixing platform 302, etc. The first base 301 is installed in the chute and is driven to move. The first fixing platform 302 is installed on the first base 301 and can rotate around it under force. The bottom of the first fixing platform 302 is weighted and can return to its initial state after each external force is removed.

[0044] A rectangular groove runs through the middle of the first fixing platform 302. The rectangular groove is larger than the size of the sensor 200. Subsequently, a first clamping member 303 and a second clamping member 304 are installed around the rectangular groove. After the first clamping member 303 and the second clamping member 304 are gathered, they enclose a loop structure to clamp and fix the sensor 200 so that it is located in the middle of the rectangular groove.

[0045] Actually, the first clamping member 303 includes two symmetrically arranged clamping plates 3031. The symmetric outer sides of the two clamping plates 3031 are fixedly connected to sliders that cooperate with a lead screw 3033. One end of the lead screw 3033 passes through the slider, and the other end is rotationally matched with the rectangular groove. The thread rotation directions of the two lead screws 3033 are opposite to each other. When the two lead screws 3033 are driven to rotate synchronously in the same direction, the two clamping plates 3031 move synchronously towards or away from each other. In order to prevent the clamping plates 3031 from rotating synchronously when the lead screw 3033 rotates, guide rods are also installed on the outer sides of the clamping plates 3031. Thus, the two clamping plates 3031 only move synchronously in the horizontal direction.

[0046] It should be noted that a first transmission rod 3032 is installed in the rectangular groove. The first transmission rod 3032 is respectively in transmission cooperation with the two lead screws 3033 through sprockets and chains. By driving the first transmission rod 3032, the movement of the two clamping plates 3031 is controlled.

[0047] In addition, the second clamping member 304 includes a clamping jaw 3041, a second elastic member 3042, etc.; a limiting groove is vertically penetrated through the middle of the clamping plate 3031. One end of the clamping jaw 3041 is bent at 90° and inserted into the limiting groove. The two clamping jaws 3041 are symmetrically distributed at both ends of the limiting groove. A second transmission rod 3034 penetrates into the limiting groove in the middle of the outer side of the clamping plate 3031. Two partitions for placing the second elastic member 3042 are symmetrically installed inside the limiting groove. The second transmission rod 3034 is located between the two partitions. A rope that is fixed to the end of the clamping jaw 3041 and wound around the second transmission rod 3034 passes through the partition. The second transmission rod 3034 is in gear transmission cooperation with the lead screw 3033 through a gear set. When the lead screw 3033 drives the two clamping plates 3031 to approach each other, the second transmission rod 3034 tightens the rope to continuously move the two clamping jaws 3041 into the limiting groove.

[0048] In the present application, the clamping claw 3041 moves synchronously with the clamping plate 3031 and is closed into a circular structure during the folding process, thereby clamping the sensor 200 and placing it in a central position.

[0049] It should be mentioned that the length of the sensor 200 is greater than the width of the clamping claw 3041 and the clamping plate 3031. When the sensor 200 is fixed in the rectangular groove, both ends thereof protrude outwards, and the protruding lengths are the same. In implementation, the sensor 200 is clamped and inserted into the rectangular groove by an intelligent mechanical arm, and the thickness of the clamping of the intelligent mechanical arm is the same as the protruding length of the sensor 200.

[0050] In the present application, the sensor 200 is clamped by a controllable first clamping member 303 and a second clamping member 304, which can avoid friction with the sensor 200 and improve stability. The multi-directional clamping can ensure that the fixed position of the sensor 200 is uniform each time.

[0051] Please participate Figures 8-11 In the present application, the positioning tool 400 is used to clamp the uncut pins 100, and after the pins 100 and the sensor 200 are welded, the pins 100 are cut, and after the cutting, the movement of the remaining pins 100 is controlled to complete the next docking. This can get rid of the operation of taking and placing the cut pins 100 each time.

[0052] Among them, the positioning tool 400 is composed of a second base 401, a second fixed platform 402, etc. The second base 401 is installed in another slide groove and supports the second fixed platform 402. The second base 401 and the second fixed platform 402 rotate in coordination. The second base 401 drives the second fixed platform 402 to move, and a driving mechanism for driving the second fixed platform 402 to rotate is installed on the second base 401. The interior of the second fixed platform 402 is hollow and a slide groove frame 403 is penetrated. The pin 100 passes through the slide groove frame 403 and slides with it. The interior of the second fixed platform 402 is divided into two, one side is installed with a transmission mechanism 500 for driving the pin 100 to move, and the other side is installed with a cutting mechanism 600 for cutting the pin 100.

[0053] First, since the pin adopts copper bars to support its hardness deviation, a slot frame 403 is provided to avoid the pin being unable to pass through the second fixed platform 402. The slot frame 403 is composed of a first slot 4031 and a second slot 4032. The first slot 4031 is used to cut a notch at the position of the pin 100, and then the second slot 4032 is filled in, so that the first slot 4031 and the second slot 4032 are slidably matched. The second slot 4032 is connected to the inner wall of the second fixed platform 402 through the first elastic member 4033. In the process of cutting the pin 100, the second slot 4032 is separated from the first slot 4031.

[0054] In this embodiment, the entire cutting process of the cutting pin 100 does not damage the chute frame 403, and the automatic reset after the separation of the chute frame 403 maintains the integrity of the chute frame 403, facilitating the insertion of the pin 100.

[0055] Secondly, the conveying mechanism 500 adopts two grinding rollers 501 symmetrically arranged on both sides of the pin 100. The friction fit is used to drive the pin 100 to move. The two grinding rollers 501 are in tooth transmission cooperation and rotate synchronously in opposite directions, and provide conveying power for one of the grinding rollers 501.

[0056] Secondly, the cutting mechanism 600 includes a blade 601, a bracket 602, a drawer 604, etc. The blade 601 is supported by the bracket 602. The bracket 602 is connected to the inner wall of the second fixing table 402 through a cylinder. The blade 601 faces the second chute 4032. Limit rods 603 are arranged at the positions on both sides of the blade 601 on the bracket 602. The limit rods 603 are longer than the diameter of the blade 601. When the blade 601 approaches the pin 100, it first contacts and presses the second chute 4032. A servo motor for driving the blade 601 to rotate is installed on the bracket 602.

[0057] A drawer 604 is installed inside the second fixing table 402. The drawer 604 is located at the bottom of the second fixing table 402 and is open upward for collecting debris that may be generated during cutting. Two first covers inclined towards the middle are symmetrically arranged at the top of the drawer 604. The middle of the two first covers is the feeding port. A conical stopper is fixed below the feeding port. The lower side of the first cover is fixed with a second cover inclined towards the stopper. The bottom of the second cover is lower than the bottom surface of the stopper. The drawer 604 fits well with the inner wall of the second fixing table 402, facilitating better collection of debris and preventing the debris from pouring out during the overall rotation of the second fixing table 402.

[0058] In some embodiments, multiple pins 100 need to be welded on one side of the sensor 200. In the second fixing table 402 of the present application, multiple chute frames 403 are arranged in parallel, and multiple grinding rollers 501 on the same side are connected in series to rotate synchronously, and multiple blades 601 are supported by the bracket 602 at the same time.

[0059] Please refer to Figures 8-9, the present application also provides a jet component 700 for delivering welding shielding gas inside the second fixing table 402. The jet component 700 includes a jet pipe 701 installed inside the second fixing table 402. One end of the jet pipe 701 is connected to a shielding gas tank at one end of the second fixing table 402, and the other end is connected to a jet branch pipe 703 outside the second fixing table 402. The jet branch pipe 703 is made of a hard anti-corrosion metal pipe. The length of the jet branch pipe 703 is the same as the length of the protruding lead 100. The jet branch pipe 703 is parallel to the lead 100 and is located on its side. A plurality of nozzles 702 facing the lead 100 are provided on the jet branch pipe 703. A multi-faceted connecting block 704 is installed on the jet branch pipe 703. When the positioning tooling 400 approaches the fixing fixture 300, the connecting block 704 is inserted into the fixing fixture 300 and meshes with it, enabling the positioning tooling 400 to be meshed and connected with the fixing fixture 300, and the fixing fixture 300 rotates synchronously during the rotation of the positioning tooling 400.

[0060] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
