DETAILED DESCRIPTION
[0028] 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.
[0029] 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.
[0030] 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.
[0031] In order to solve the above problems, the present embodiment provides a flexible vibration plate loading mechanism and a probe automatic assembly machine, wherein the flexible vibration plate loading mechanism comprises: a fixed base and a vibration component located on the upper surface of the fixed base; the vibration component comprises: a backlight vibration plate and a vibration loading bin located above the backlight vibration plate; the probe components are placed into the vibration loading bin and enter the backlight vibration plate through the loading port of the vibration loading bin to realize automatic loading of the probe components, thereby avoiding the disadvantage of manual loading and improving the efficiency of probe assembly.
[0032] In the first aspect, this embodiment provides a flexible vibration plate feeding mechanism, such as Figure 1 As shown, including:
[0033] A fixed base 110 and a vibration component located on the upper surface of the fixed base 110; the vibration component includes a backlight vibration plate 10 and a vibration loading bin 20 located above the backlight vibration plate.
[0034] Furthermore, the backlight vibration tray 10 includes: a vibration tray 101 and a first vibration base 102 located below the vibration tray.
[0035] The vibrating loading bin 20 includes: a bin 201, a loading adjustment baffle located at the front end of the bin 201, and a second vibrating base located below the bin; a discharge port is provided at one end of the bin 201, and the discharge port is correspondingly provided above the vibrating tray 101.
[0036] Combination Figure 1 As shown, a vibration component is arranged on the fixed base 110, and the vibration component includes a backlight vibration plate 10 and a vibration loading bin 20. The vibration loading bin 20 is located above the backlight vibration plate 10. Therefore, the positions of the parts located in the vibration loading bin change during the vibration process, and gradually change and fall into the backlight vibration plate located below the vibration loading bin, so that the parts of the probe can be obtained from the backlight vibration plate.
[0037] Furthermore, the backlight vibration tray 10 includes: a vibration tray 101 and a first vibration base 102 arranged in sequence from top to bottom. The vibration tray 101 is used to place the parts dropped from the vibration upper bin 20, and the first vibration base 102 drives the vibration tray 101 to vibrate while supporting the vibration tray 101, so as to prevent the probe parts dropped into the vibration tray 101 from being stacked under the vibration upper bin, thereby causing the problem of inconvenience in picking up.
[0038] In order to drive the vibration tray, a vibration assembly is provided under the vibration tray to drive the vibration tray to vibrate synchronously. In one embodiment, a first vibration base is installed under the vibration tray, and the first vibration base includes a first vibration motor and a first vibration base; the first vibration motor drives the first vibration base to vibrate to drive the vibration tray to vibrate synchronously. In order to achieve a better driving effect, the shape design of the first vibration base is adapted to the shape of the vibration tray, for example: if the shape of the vibration tray is designed to be square, the shape of the first vibration base is also designed to be square.
[0039] Furthermore, in order to achieve better storage of components and prevent the difficulty of picking up components due to large changes in their positions during the vibration process, in this embodiment, the vibration tray is configured as a groove structure, and a plurality of protrusion structures are provided on the inner surface of the groove. This allows the vibration amplitude of the components to be limited during the vibration of the components in the vibration tray to prevent the vibration amplitude from being too large, which may cause inconvenience in picking up.
[0040] A vibrating loading bin is arranged above the vibrating tray. Figure 1 As shown, the vibrating loading bin includes: a bin 201, a loading adjustment baffle located in the bin 201, and a second vibrating base 202 located below the bin. A discharge port is provided at one end of the bin, and the discharge port is correspondingly provided above the vibrating tray. It is conceivable that the vibrating loading bin can be set to have a preset inclination angle so that the parts placed in the bin are gradually vibrated to the discharge port at a lower position, and then smoothly flow into the vibrating tray. In addition, in the specific implementation, the bin can also be set to consist of a discharge port located at the front end and a storage chamber located at the rear end, and the loading adjustment baffle separates the front end and the rear end, so that while controlling the number of parts flowing into the vibrating tray, it is also convenient to control the number of parts flowing from the storage chamber through the loading adjustment baffle into the discharge port, thereby achieving a better loading effect.
[0041] Furthermore, in order to facilitate the control of the number of parts flowing into the vibration tray, one or more feed ports can be set on the loading adjustment baffle. The parts located in the silo are transported to the vibration tray through the feed port and the discharge port to avoid accumulation of parts due to too many parts entering the vibration tray, thereby increasing the difficulty of picking up parts.
[0042] Further, such as Figure 1 As shown, the vibrating upper bin 20 also includes a second vibrating base 202 located below the bin 201. The second vibrating base 202 includes a second vibrating base, a second vibrating motor located below the second vibrating base for driving the second vibrating base to vibrate, and an adjusting bracket 203 for adjusting the height of the vibrating upper bin and the second vibrating base.
[0043] Since the adjustment bracket 203 is provided to facilitate adjustment of the distance between the discharge port of the vibrating loading bin and the vibrating tray, the vibration of the second vibrating motor can also be buffered.
[0044] Furthermore, in order to facilitate further control of the number of parts flowing into the vibrating tray, an adjustment member is provided on the feeding adjustment baffle plate, which is used to adjust the distance between the bottom of the feeding adjustment baffle plate and the inner surface of the silo. The adjustment member can adjust the height difference between the feeding adjustment baffle plate and the side walls on both sides of the material layer, and by adjusting a parts outlet under the feeding adjustment baffle plate, the parts at the rear end of the silo can flow into the front end. Since the size of the outlet can be adjusted as needed, the flow of parts can be controlled.
[0045] Combination Figure 1 As shown, a fixed bracket 301 is further provided on the fixed base or on the side of the fixed base, and a positioning member 302 and a connecting member for connecting the positioning member 302 to the fixed bracket are provided above the fixed bracket 301:
[0046] The positioning member 302 is disposed corresponding to the vibration tray 101 and is used for identifying the positions of components in the vibration tray 101 .
[0047] Specifically, the positioning member is used to identify the position of the parts in the vibration tray so as to facilitate picking up the parts. Since the positioning member is used to identify the position of the parts in the vibration tray, a fixed bracket is used to fix the positioning member above the vibration tray so as to obtain the image of the parts by using the positioning member, and then identify the image of the parts and locate the precise position of the parts.
[0048] In one embodiment, the positioning member fixedly arranged on the vibrating loading layer by the fixed bracket includes: a camera module for taking an image of the interior of the vibrating tray and locating the position of the components according to the image of the interior of the vibrating tray.
[0049] Furthermore, when the camera module captures the image of the component and analyzes the component image to determine the position information of the component, it is also necessary to send out the located position information so that the component picking mechanism can pick up the component. Therefore, the positioning part also includes: a communication module for transmitting the located component position, and the communication module is electrically connected to the camera module.
[0050] The flexible vibration plate feeding mechanism disclosed in this embodiment can realize automatic feeding of parts, thus avoiding the time-consuming, labor-intensive and inefficient manual picking of precise and small parts, and meeting the needs of large-scale production of probes.
[0051] In a second aspect, this embodiment also provides a probe automatic assembly machine, such as Figure 2 As shown, it includes: the flexible vibration plate feeding mechanism.
[0052] 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.
[0053] Combination Figure 2 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.
[0054] 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.
[0055] 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.
[0056] 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.
[0057] Specific tests include: CCD visual detection components and force test components. CCD visual detection components are used to detect the dimensions of assembled probes. Force test components are used to detect the force of assembled probes. Specifically, the positioned products are driven by servo motors to perform contact force tests on force test components to ensure that the force of components is within the tolerance range.
[0058] In addition, you can also set up a force-checking PPU handling module: the product is transported to the next module through the PPU transverse movement module, and a finished product discharge counting module: the parts transported from the upper workstation are counted and enter the packaging box through the guide groove.
[0059] The present embodiment provides a flexible vibration plate feeding mechanism and a probe automatic assembly machine, the flexible vibration plate feeding mechanism includes: a fixed base and a vibration component located on the upper surface of the fixed base; the vibration component includes: a backlight vibration plate, a vibration feeding bin located above the backlight vibration plate; the backlight vibration plate includes a vibration tray, a backlight module located below the vibration tray, and a first vibration base; the vibration feeding bin includes: a bin, a feeding adjustment baffle located at the front end of the bin, and a second vibration base located below the bin; a discharge port is provided at one end of the bin, and the discharge port corresponds to the top of the vibration tray. The feeding mechanism provided in the present embodiment utilizes the backlight vibration plate in the vibration component and the vibration feeding bin located above the backlight vibration plate to realize automatic feeding of probe parts, thereby avoiding the disadvantage of manual feeding and improving the efficiency of probe assembly.
