DETAILED DESCRIPTION

[0033] 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.

[0034] 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.

[0035] 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 is required. However, due to the small size of the components of the probe, manual sorting requires a lot of manpower costs, and the manual operation efficiency is low and the rate of unqualified products is high. Therefore, it cannot meet the needs of large-scale and high-volume production.

[0036] In order to solve the above problems, the present embodiment provides a rotary clamping rolling mechanism, wherein a rolling assembly is used to apply pressure to a rolling wheel, and the rolling wheel rolls the assembly to control the size of the assembly; a clamping rotating device is used to rotate the parts to realize the assembly of the parts, and a positioning assembly is used to position the parts or assemblies to realize the automatic assembly of the probe parts, thereby avoiding the disadvantage of manual loading and improving the efficiency of probe assembly.

[0037] In a first aspect, this embodiment provides a rotary clamping rolling mechanism, such as Figure 1 As shown, it includes: a rolling assembly 150, a clamping and rotating device 130 and a positioning assembly located on the side of the rolling assembly 150.

[0038] The rolling assembly 150 includes a rolling wheel 110 and a rolling control member connected to the rolling wheel 110 , wherein the rolling control member applies pressure to the rolling wheel.

[0039] The clamping and rotating device 130 includes: a clamp, a transmission shaft fixedly connected to the clamp, and a power element for driving the rotating transmission shaft to rotate;

[0040] The positioning assembly includes: a positioning element for positioning a component or a product.

[0041] Combination Figure 2 As shown, the rotary clamping and rolling mechanism disclosed in this embodiment is arranged on a platform, and the base is used to bear the weight of the entire rotary clamping and rolling mechanism. The clamping and rotating device, the positioning assembly and the rolling assembly are respectively provided with corresponding fixed bases and fixed to the platform through the fixed bases.

[0042] Combination Figure 1 and Figure 2 As shown, the roller of the rolling assembly is located in the middle of the entire rotary clamping rolling mechanism, the positioning assembly and the rotary clamping device are located on one side of the roller, and the other components of the roller assembly are located on the other side of the roller.

[0043] Furthermore, in order to position each component and the assembled product separately for rotation, rolling and other processing, the positioning element includes a component positioning member 120 and a product positioning member 140. The component positioning member is used to position each component, and the product positioning member is used to position the assembled product.

[0044] Specifically, Figure 3 As shown, the component positioning member 120 includes: a first clamping element 1201, a first positioning element, a first transmission element 1202 providing power to the first clamping element 1201 and the first positioning element, and a first guide element controlling the movement direction of the first clamping element 1201 and the first positioning element.

[0045] The product positioning member 140 includes: a second clamping element 1402, a second positioning element, a second transmission element providing power to the second clamping element and the second positioning element, and a second guide element 1401 controlling the movement direction of the second clamping element and the second positioning element.

[0046] Specifically, in a specific application, the first clamping element and the second clamping element directly clamp the probe component or assembled product to be positioned, limiting the freedom of the probe component or assembled product. The first clamping element is connected to the first transmission element, and the second clamping element is connected to the second transmission element. The first clamping element and the second clamping element move under the control of the first transmission element and the second transmission element respectively, and the moving path of the first clamping element is limited by the first guide element, and the moving path of the second clamping element is limited by the second guide element, and moves along the path defined by the first guide element or the second guide element.

[0047] Combination Figure 1-Figure 3 As shown, in one implementation, the first guide element and the second guide element are two linear sliding guide rails arranged in a vertical direction. The first positioning element and the second positioning element are positioning holes or positioning pins. The first transmission element and the second transmission element are servo motors, AC motors, cylinders or pneumatic motors.

[0048] Specifically, the first positioning element is a positioning pin, the second positioning element is a positioning hole, and the first positioning element and the second positioning element are both arranged at the front end of the positioning piece to facilitate positioning of components and products.

[0049] Furthermore, the rolling control component includes a base, a first fixed seat and a second fixed seat arranged on the base; a roller is installed on the first fixed seat for fixing the roller; and an oil cylinder is installed on the second fixed seat for adjusting the forward and backward positions of the roller.

[0050] The roller is mounted on a fixed seat of the rolling control component and its position is adjusted by an oil cylinder. The rolling control component also includes a wheel rod and a drive motor; the wheel rod is connected to the roller and drives the roller to rotate or feed under the power provided by the drive motor.

[0051] Specifically, the rolling assembly is further provided with a sliding seat, and the oil cylinder located on the second fixed seat is connected to the sliding seat to control the feeding and retraction of the sliding seat, thereby driving the roller assembly to apply pressure to the assembled probe components.

[0052] Furthermore, the rolling assembly also includes: a control system and a cooling and lubrication system. The control system adjusts the action of the oil cylinder through electrical signals, and also monitors and adjusts the entire rolling process. The cooling and lubrication system is connected to the rolling area through pipelines to provide necessary coolant and lubricant for the rollers and other components.

[0053] In order to better control the clamping force of the clamping and rotating device or monitor its working state, the clamping and rotating device further includes a pressure sensor connected to the clamp. The pressure sensor can be a limit switch, a photoelectric sensor, a proximity sensor, etc., which is used to monitor the position of the parts, ensure that the parts are correctly positioned or detect the clamping state, and feed back the detected information to the control system.

[0054] The rotary clamping and rolling mechanism disclosed in this embodiment receives various probe components and sequentially installs the probe components into the probe cover according to the assembly sequence. The rotary clamping device automatically rotates and clamps the assembly obtained after the assembly is installed into the probe cover, and under the drive of the positioning component and the rolling mechanism, the assembly is rolled to a preset size to obtain an assembled probe.

[0055] The rotary clamping and rolling mechanism disclosed in this embodiment can automatically realize the assembly of the probe and control the size of the assembled probe, thereby improving the assembly efficiency and saving human resources, and is suitable for large-scale use.

[0056] In a second aspect, this embodiment also provides a probe automatic assembly machine, such as Figure 4 As shown, it includes: the rotating clamping and rolling mechanism.

[0057] The probe automatic assembly machine provided in this embodiment uses the flexible vibration plate feeding mechanism provided in the above embodiment to feed the various parts of the probe to realize the assembly of the probe. Since the parts of the probe include: a probe head, a spring and a probe cover, in the specific implementation, combined with Figure 1 and Figure 2 As shown, the probe automatic assembly machine includes three sets of the above-mentioned flexible vibration plate feeding mechanisms to feed the probe head, spring and probe cover respectively, and assemble the picked-up probe head, spring and probe cover together to form a probe.

[0058] Combination Figure 4 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] Specifically, the detection device includes: a dimension detection component and a force testing component. The dimension detection component is used to perform dimension detection on the assembled probe to determine whether it meets the preset dimension requirements, and the force testing component is driven by a servo motor to perform contact force detection on the positioned product to ensure that the force of the components is within the tolerance range.

[0063] In addition, the probe automatic assembly machine can also be provided with a force inspection PPU transport module, which transports the product to the next module through the PPU transverse movement module, and a finished product discharge counting module, which counts the transported parts and enters the packaging box through the guide groove.

[0064] The present embodiment provides a rotary clamping rolling mechanism and a probe automatic assembly machine, the rotary clamping rolling mechanism comprises: a rolling assembly, a clamping rotating device and a positioning assembly; the rolling assembly comprises: a rolling wheel and a rolling control member connected to the rolling wheel, the rolling control member applies pressure to the rolling wheel; the clamping rotating device comprises: a clamp, a transmission shaft fixedly connected to the clamp and a power element driving the rotating transmission shaft to rotate; the positioning assembly comprises: a positioning element for positioning parts or products. The rotary clamping rolling mechanism provided in the present embodiment uses a rotary clamping device to rotate the probe parts, uses a positioning assembly to position and assemble the probe parts together, and then uses a rolling control member to roll the probe assembly to obtain an assembled probe. Since the rotary clamping rolling mechanism disclosed in the present embodiment can realize automatic positioning and assembly of probe parts, it avoids the disadvantages of low efficiency, low finished product qualification rate, high labor cost, etc. caused by manual assembly, improves the efficiency of probe assembly, the finished product qualification rate and saves labor cost.
