The control device is a computer or PLC, etc. The control device is used to connect and control the coordination of various devices. The transmittance detection equipment may also include a protective cover connected to the frame. The above devices and modules may be arranged in the protective cover.

[0037] A camera can also be set at the discharge end of the transmittance detection equipment to take pictures of qualified workpieces. The camera is connected to the server. The transmittance detection device 400 is also connected to the server to upload the workpiece data to the server for data traceability.

[0038] In this embodiment, the transport suction cups are arranged in a straight line on the transport jig plate.

[0039] Four transmittance suction cups are equally spaced around the circumference of the transmittance fixture plate.

[0040] like Figure 3 The buffer streamline 200 shown includes: a conveyor belt conveyor, and two transverse material blocks 201 and two longitudinal material blocks 202 installed on the conveyor belt conveyor. The transverse material blocks 201 form three parallel conveying channels above the conveyor belt conveyor, and the two longitudinal material blocks 202 are arranged at the ends of the conveying channels on both sides and are located in the middle of the conveyor belt conveyor, so that the conveying channels on both sides are terminated in the middle of the conveyor belt conveyor.

[0041] Regarding the transporting and moving mechanism, the transporting and moving mechanism includes: a transporting transverse moving mechanism 101 , a transporting longitudinal moving mechanism 102 , and a transporting and lifting moving mechanism 103 connected in sequence, and the transporting suction fixture 105 is connected to the transporting and lifting moving mechanism 103 .

[0042] In this embodiment, the transporting and moving mechanism further includes: a transporting and rotating mechanism 104 , and the transporting and sucking fixture 105 is connected to the transporting and lifting and moving mechanism 103 via the transporting and rotating mechanism 104 .

[0043] Regarding the transmittance moving mechanism 301, the transmittance moving mechanism 301 is a manipulator, such as Figure 1 , 2 The transmittance moving mechanism 301 shown in FIG4 is a four-axis manipulator.

[0044] In this embodiment, the transmittance detection equipment further includes: a defective product conveyor 600 , and the defective product conveyor 600 is arranged between the transmittance detection device 400 and the defective transmittance product area 500 .

[0045] Transporting defective workpieces by the defective product conveyor 600 can reduce the moving distance of the transmittance material taking device 300 and improve the working efficiency of the transmittance material taking device 300.

[0046] The transmittance detection device 400 is a transmittance detection device 400 of the LPKF-TMG03 model. In this embodiment, a workpiece is qualified if the transmittance value detected is greater than 40%.

[0047] Working principle: Based on the first working method of the above embodiment: the transport module 100 absorbs the workpiece and moves to the top of the cache streamline 200, so that several workpieces on the transport module 100 are arranged horizontally on one side of the cache streamline 200. The transport module 100 arranges several workpieces horizontally on the other side of the cache streamline 200 when moving the workpiece next time, and uses the longitudinal blocking member 202 to block the movement of the workpiece so that the workpieces on both sides are aligned.

[0048] Then the transmittance suction cups at both ends of the transmittance picking device 300 pick up two workpieces from both sides above the cache streamline 200 for transmittance inspection. When the two workpieces pass the transmittance inspection, the transmittance picking device 300 rotates the two workpieces 90° and places them in the upper middle part of the cache streamline 200. In the process of placing the two workpieces in the upper middle part of the cache streamline 200, the transmittance picking device 300 simultaneously picks up two workpieces from both sides above the cache streamline 200, so that the transmittance picking device 300 picks up two workpieces for inspection each time it puts down two qualified workpieces.

[0049] When the workpiece fails the transmittance detection, the transmittance picking device 300 moves the unqualified workpiece to the transmittance defective product area 500 and puts the workpiece down, or puts the workpiece down on the defective product conveyor 600 and moves the unqualified workpiece to the transmittance defective product area 500 through the defective product conveyor 600.

[0050] A second working method based on the above embodiment: the transport module 100 places the workpiece into three conveying channels, wherein when the second workpiece is placed into the middle conveying channel, the first workpiece in the middle conveying channel is moved to a predetermined position by the conveyor belt conveyor, and then the transport module 100 places the second workpiece into the middle conveying channel.

[0051] After the four workpieces are placed in the three conveying channels, the conveyor belt drives the four workpieces to move, and the longitudinal blocking member 202 blocks the movement of the workpieces in the conveying channels on both sides, so that the workpieces in the conveying channels on both sides are located in the middle position of the two workpieces in the middle conveying channel.

[0052] Then the transmittance picking device 300 simultaneously sucks up the four workpieces and moves them to the working position of the transmittance detection device 400 for transmittance detection. The difference from the first working method is that the second working method can realize one movement of the transmittance picking device 300 and simultaneously suck up four workpieces for detection, which greatly improves the work efficiency.

[0053] When performing transmittance detection, the transmittance material taking device 300 places the workpiece on the working position of the transmittance detection device 400 to perform transmittance detection.

[0054] When performing transmittance detection, the transmittance data of 8 points of each workpiece are measured respectively, and 32 transmittance data of four workpieces are measured.

[0055] After the inspection is completed, the 8 transmittance data corresponding to each qualified workpiece are uploaded to the server in the form of a report.

[0056] In the second embodiment, the position of the transport suction cup is changed based on the first embodiment.

[0057] In this embodiment, the transport suction cups are arranged at equal points in a circle or arranged in a straight line on the transport jig plate.

[0058] The transmittance suction cups are arranged on the transmittance fixture plate at equal points in a circle or arranged in a straight line.

[0059] The distribution positions of the transport suction cups correspond to the distribution positions of the transmittance suction cups, that is, the transport suction cups and the transmittance suction cups are equally divided on the circumference, or the transport suction cups and the transmittance suction cups are arranged in a straight line, and the transport suction cups and the transmittance suction cups are arranged at the same spacing.

[0060] After the workpieces are arranged and absorbed by the transport module 100, the transport module 100 places the workpieces on the buffer streamline 200 and the transmittance picking device 300 can directly pick up the workpieces for transmittance detection, thereby reducing the work flow of the transmittance picking device 300 and reasonably allocating the working time to the transport module 100 and the transmittance picking device 300, thereby improving work efficiency.

[0061] In the third embodiment, the structure of the transmittance moving mechanism 301 is changed on the basis of the first or second embodiment.

[0062] In this embodiment, the transmittance moving mechanism 301 includes: a transmittance transverse moving mechanism, a transmittance longitudinal moving mechanism and a transmittance lifting moving mechanism connected in sequence, and the transmittance suction fixture 302 is connected to the transmittance lifting moving mechanism.

[0063] In a further embodiment, the transmittance moving mechanism 301 further includes: a transmittance rotating mechanism, and the transmittance suction fixture 302 is connected to the transmittance lifting and moving mechanism through the transmittance rotating mechanism.

[0064] The fourth embodiment further defines the structure of the transmittance jig plate based on the first, second or third embodiment.

[0065] The light transmittance jig plate comprises: four support plates, the four support plates are arranged in a "cross" structure, and four light transmittance suction cups are arranged at the ends of the four support plates.

[0066] The width of the support plate is smaller than the width of the workpiece, and the distance between the transmittance suction cup and the edge of the end of the support plate is smaller than the distance from the edge of the workpiece to its center.

[0067] When the transmittance absorbing jig 302 moves to the working position of the transmittance detection device 400 , the transmittance moving mechanism 301 drives the transmittance absorbing jig 302 to rotate, so that the transmittance detection device 400 sequentially performs transmittance detection on the workpieces on the transmittance absorbing jig 302 .

[0068] In a further embodiment, only the distance between the conveying channels on both sides is increased, so that when the transmittance material picking device 300 sucks the workpiece twice, the workpiece and the transmittance suction cup can be set in an eccentric structure, thereby reducing the obstruction of the support plate to the workpiece and increasing the detectable range.

[0069] By increasing the distance between the conveying channels on both sides and increasing the placement time of the two workpieces in the middle conveying channel, when the transmittance material picking device 300 sucks the workpiece at one time, the center distance between the workpieces can be made larger than the center distance between the transmittance suction cups, so that the workpiece and the transmittance suction cup are set in an eccentric structure, reducing the obstruction of the support plate to the workpiece and increasing the detectable range.

[0070] By setting the support plate width and the position of the transmittance suction cup, the workpiece can be partially located outside the support plate after the transmittance suction cup absorbs the workpiece, and the transmittance detection of the workpiece can be performed without putting the workpiece down, which greatly improves the transmittance detection efficiency. Moreover, compared with the existing method of putting the workpiece down for fixed-point detection, the transmittance detection performed in the process of the transmittance moving mechanism 301 driving the workpiece to move is an arc path detection of the workpiece, which increases the detection points and improves the detection accuracy.

[0071] Since the transmittance detection device 400 has extremely high accuracy and cost, the non-contact and non-stop detection can also reduce the wear of the transmittance detection device 400, greatly reducing the cost of equipment use.

[0072] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
