DETAILED DESCRIPTION

[0027] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0028] In the manufacturing process of printed circuit boards, it is usually necessary to use a probe to detect the printed circuit boards to determine whether the conductive points on the printed circuit boards can conduct electricity normally. Therefore, the probe is an important detection tool in the manufacturing process of printed circuit boards.

[0029] The probe is generally composed of a probe head, a spring and a probe cover. In the existing manufacturing process of the test probe, manual operation, manual sorting and assembly are required. However, due to the small size of the components of the probe, manual sorting and oiling require a lot of manpower costs, and the manual operation efficiency is low and the defective rate is high, so it cannot meet the needs of large-scale high-volume production.

[0030] Furthermore, before assembling the probe head, spring and probe cover together, a certain amount of lubricating oil needs to be sprayed into the probe cover to prevent the spring from wearing the inside of the probe cover and itself due to constant friction with the inner wall of the probe cover during operation. Spraying a certain amount of lubricating oil can form a lubricating film to reduce the contact between the spring and the inner wall of the probe cover, thus avoiding friction and wear. In the prior art, oiling is generally done manually, which not only increases a lot of labor costs, but also has low efficiency and accuracy, and also cannot meet the needs of mass production.

[0031] In order to solve the above problems, this embodiment provides an oil dosing control mechanism and an automatic probe assembly machine, the oil dosing control mechanism includes: a fixed bracket and an oil supply control component and an oil tank located on the fixed bracket; the oil supply control component includes: a nozzle, an oil supply control element and a pressure control element for controlling the oil injection time and amount of the nozzle; the nozzle is connected to the output end of the oil supply control element; the oil supply control element is connected to the oil tank, and draws or pushes oil from the oil tank to the nozzle; the pressure control element is connected to the oil supply control element. The oil dosing control mechanism provided in this embodiment can realize automatic oil dosing of probe parts, so as to overcome the problems of labor waste, large oil dosing amount deviation, inaccurate oil dosing position or waste of oil resources caused by manual oil dosing, and improve the efficiency of probe assembly.

[0032] In the first aspect, this embodiment provides an oil point control mechanism, such as Figure 1 As shown, it includes: a fixed bracket 120 and an oil supply control component and an oil tank 140 located on the fixed bracket 120.

[0033] The oil supply control assembly includes: a nozzle 110, an oil supply control element 160 for controlling the oil injection time and oil injection amount of the nozzle 110, and a pressure control element 150;

[0034] The fixed bracket 120 includes a main bracket and a support plate fixed to one side of the top of the main bracket; the spray head 110 and the oil supply control element 160 are arranged on the support plate.

[0035] The nozzle 110 is connected to the output end of the oil supply control element 160; the oil supply control element 160 is connected to the oil tank 140, and draws or pushes oil from the oil tank 140 to the nozzle 110; the pressure control element 150 is connected to the oil supply control element 160, and injects pressure into the oil supply control element 160.

[0036] Specifically, the fixed support 120 includes a T-shaped main support and a support plate fixed to one side of the top of the main support. The nozzle 110 and the oil supply control element 160 are arranged on the support plate. Figure 2 As shown, the oil supply control element 160 is in a rectangular shape as a whole, and the side surfaces of the support plate and the main bracket form a linear groove, and the nozzle 110 and the oil supply control element 160 are placed in the linear groove.

[0037] In order to spray the oil in the oil tank from the nozzle at a certain time interval and a fixed flow rate, the oil supply control element is connected to a pressure control element, and the pressure control element is a pressure pump. The pressure pump is connected to one end of the oil supply control element, and the nozzle is connected to the other end of the oil supply control element. The pressure pump is used to deliver pressure to the oil supply control element so that the oil supply control element extracts or pushes a certain amount of oil from the oil tank to the nozzle. The pressure pump is cylindrical in shape, and the pressure pump uses electricity or compressed gas as a power source to continuously or intermittently deliver the oil in the oil tank to the nozzle. In order to achieve accurate control of the delivered oil, the oil supply control element controls the oil supply amount and the time of oil supply.

[0038] Furthermore, the pressure pump is also connected to an air purification component. The air compressed into the pressure pump is first purified by the filter layer contained in the air purification component. The purified air enters the pressure pump to effectively remove pollutants such as tiny particles or bacteria in the air, thereby keeping the oil point control mechanism in a clean environment.

[0039] Furthermore, the nozzle is conical in shape to facilitate receiving the oil transmitted by the oil supply control element while ensuring the accuracy of the oil injection position. The end with a larger outer diameter is connected to the output end of the oil supply control element, and the other end is needle-shaped for oil injection.

[0040] The end with a larger outer diameter in the nozzle is embedded in the oil output end of the oil supply control element, and the connection between the nozzle and the oil supply control element is further fixed by a fixing component to strengthen the fixed connection between the nozzle and the oil supply control element to avoid air leakage, oil leakage and the like, which will not only lead to the inability to perform the oil injection operation normally, but also cause problems such as oil waste.

[0041] In one implementation, combining Figure 2 As shown, the fixing assembly includes a fixing screw, a fastener, and at least one limiting strip 210 disposed in the fastener, and the limiting strip 210 is used to prevent the nozzle 110 from being dislocated. In a specific implementation, the number of the limiting strips 210 can be one or more, which are respectively snapped at the connection between the nozzle 110 and the fastener. Specifically, the fastener is a cylindrical bearing shaft with an internal thread. The fixing screw is sleeved on the fastener, and the fastener is sleeved on the rear end of the nozzle.

[0042] Further, combined with Figure 2As shown, the nozzle is also connected to a calibration plate 180, and the calibration plate 180 is sleeved on the front end of the nozzle 110. Before the oil point control mechanism disclosed in this embodiment starts to work, the calibration plate 180 is snapped onto the nozzle to calibrate the nozzle position, so as to avoid the situation that the nozzle position is offset, resulting in a small oil output, failure to align with the probe cover, oil leakage, and other situations where the probe cover cannot be normally oiled.

[0043] Combination Figure 2 As shown, a calibration port 220 is provided on the calibration plate 180. When the nozzle is calibrated, the needle tube of the nozzle is placed in the calibration port to achieve calibration of the nozzle position.

[0044] Further, combined with Figure 1 As shown, a pressure gauge is provided on the oil tank, and the pressure in the oil tank is detected by the pressure gauge to avoid abnormal oil output caused by excessive or insufficient pressure.

[0045] Furthermore, the oil tank may be connected to an oil level indicator, which is in communication with the oil tank. The oil level indicator displays the real-time oil level in the oil tank, so that the operator can know the oil level in the oil tank in time, thereby avoiding oil filling failure due to insufficient oil.

[0046] Furthermore, the oil supply control element includes an electronic controller and a flow controller. The electronic controller is connected to the pressure pump and is used to control the opening and closing time of the pressure pump; the flow controller is connected to the oil supply control element and is used to collect the outflowing oil volume.

[0047] The electronic controller and the flow controller are used to control the time and amount of oil injection in the nozzle, thereby realizing automatic oiling of the probe parts, saving human resources and improving work efficiency. Furthermore, the electronic controller and the flow controller are connected to the pressure pump through wires.

[0048] Combination Figure 1 and Figure 2 As shown, the oil supply control element 160 is arranged on the top of the fixed bracket 120, and the oil tank 140 and the pressure control element 150 are arranged on the side of the fixed bracket 120. In this embodiment, the oil supply control element and the nozzle are arranged on the top of the fixed bracket to facilitate the control of oil output, and the pressure control element and the oil tank are arranged on the side of the fixed bracket 120 to achieve high integration of the overall oil point control mechanism, and small size, which is easier to operate and use.

[0049] The oil dosing control device disclosed in this embodiment can automatically perform the oil dosing operation on the probe cover, thereby realizing automation of the oil dosing control process, and the oil dosing control is realized based on the controller, which can achieve precise control of the oil dosing amount and the oil dosing position, thereby achieving a better oil dosing effect.

[0050] In a second aspect, this embodiment also provides a probe automatic assembly machine, such as Figure 3 As shown, it includes: the oil point control mechanism.

[0051] The automatic probe assembly machine provided in this embodiment uses the oiling control mechanism provided in the above-mentioned embodiment to oil the probe components. In specific implementation, the oiling control mechanism can control the oil injection at fixed time intervals to achieve oiling of the probe cover located in front of the nozzle. The oiling control mechanism can also be provided with a sensor to determine whether there is a probe cover in front. When the probe cover is located in front of the nozzle, the oil injection is controlled, and the probe cover after oil injection is assembled with the probe head and the spring to form a test probe.

[0052] Combination Figure 3 As shown, the probe automatic assembly machine includes: a chassis 400, a flexible vibration plate feeding mechanism 100 arranged above the chassis, a robot picking mechanism 200, an oil dot control mechanism 300 and a detection device 500, etc.

[0053] In the specific implementation, since there are three kinds of parts of the probe, three groups of flexible vibration disk feeding mechanisms are set up respectively, and different parts are placed in the material bins of the three flexible vibration disk feeding structures respectively. Under the vibration of the second vibration base, the parts flow into the backlight vibration disk from the discharge port. At the same time, the positioning part located on the backlight vibration disk takes a picture of the backlight vibration disk, and analyzes the picture to obtain the position information of the probe parts in the backlight vibration disk, and transmits the located part position information to the robot picking mechanism.

[0054] The mechanical picking mechanism automatically calculates and picks up the corresponding parts through the position information transmitted from the positioning parts in the flexible vibration plate feeding mechanism, and places the sucked parts to the specified position.

[0055] After the mechanical pickup mechanism rotates the sucked probe head component to the specified position, the oil injection module controls the output size and time of the oil volume and injects a fixed amount of oil into the probe cover. When the robot assembles all the mechanical parts into the probe cover in sequence, the assembly and inspection device automatically clamps the mechanical parts and rolls the assembled probe assembly to the standard size, and inspects the probe products rolled to the standard size.

[0056] The specific detection device includes: CCD visual detection component and force test component. The CCD visual detection component is used to detect the size of the assembled probe to determine whether the size of the assembled probe is within the specified range, and the positioned product is driven by the servo motor to perform contact force detection on the force test component to ensure that the force of the parts is within the tolerance range.

[0057] In addition, you can also set up a force check PPU handling module: the product is transported to the next module through the PPU transverse movement module, and the finished product discharge counting module counts the transported parts and puts them into the packaging box through the guide groove.

[0058] The present embodiment provides an oiling control mechanism and a probe automatic assembly machine. The oiling control mechanism can realize automatic oiling of probe components to overcome the problems of labor waste, large deviation in oiling amount, inaccurate oiling position or waste of oil resources caused by manual oiling. It saves labor costs, has a high degree of automation, and the oiling amount can be precisely controlled and stabilized, thereby improving the efficiency of probe assembly.
