Description

Technical Field

[0001] The present invention relates to the technical field of touch screen function chip detection, and particularly relates to a circuit detection device for touch screen function chips. Background Art

[0002] With the rapid development and wide application of touch screen technology in various electronic products, such as smart phones, tablet computers, notebook computers, and various intelligent terminal devices, the quality requirements for touch screen function chips are also increasing day by day. As one of the core components of the touch screen, the quality and performance of the touch screen function chip directly affect the user experience of the final product. Therefore, strict functional testing of the touch screen function chip during the production process is an essential link.

[0003] Currently, when performing functional testing on touch screen function chips, usually, testers manually place the function chip to be tested in the working area of the testing device, adjust the position of the function chip to be tested to align it with the probes or test contacts of the testing device, and then control the probes or test contacts of the testing device to precisely contact the bonding area of the function chip. Subsequently, the testing program is started. After the testing is completed, the operator needs to manually remove the tested function chip and then replace it with a new sample to be tested, repeating the above steps. Although this traditional testing method is simple and direct, in the face of a large-scale mass production environment, it obviously exposes the problems of low efficiency and high labor costs. Especially in the modern manufacturing environment pursuing high production volume, the time required for each step will accumulate significantly, increasing the production cycle and reducing the overall work efficiency. In addition, manual operation will inevitably introduce the risk of human error, affecting the accuracy of the test results. Summary of the Invention

[0004] In view of this, the present invention provides a circuit detection device for touch screen function chips, which can overcome the disadvantages that when performing functional testing on existing touch screen function chips, manual operation is frequently required, which is not only time-consuming and laborious, with low work efficiency, but also affects the accuracy of the test results.

[0005] The technical solution is as follows: A circuit detection device for touch screen function chips includes: a mounting bracket; a controller mounted on the mounting bracket; a turntable rotatably connected to the mounting bracket; a first driving motor mounted on the mounting bracket, and the output shaft of the first driving motor is connected to the bottom of the turntable; a fixed frame circumferentially and spacedly connected to the top of the turntable; first electric push rods symmetrically mounted on the top of the turntable; first suction cups mounted on the telescopic rods of the first electric push rods, and the first suction cups slidably penetrate through the side surface of the fixed frame; a testing component arranged on the mounting bracket for performing functional testing on the touch screen function chips; a material taking component arranged on the mounting bracket for taking out the touch screen function chips with abnormal functions in the placement frame.

[0006] Further, the test component includes: a guide post connected to the mounting bracket; second electric push rods symmetrically mounted on the mounting bracket; a first lifting plate slidably connected to the guide post, and the first lifting plate is connected to the telescopic rods of the second electric push rods; a partition frame connected to the bottom of the first lifting plate; a connecting frame spacedly connected to the bottom of the first lifting plate; test contacts spacedly mounted on the inner side of the connecting frame, the test contacts contacting the binding area of the touch screen function sheet to perform functional tests on the touch screen function sheet; a marking mechanism arranged on the first lifting plate for marking the touch screen function sheets with abnormal functions in the marking area of the placement frame.

[0007] Further, the marking mechanism includes: a first guide rod connected to the first lifting plate; a sliding seat slidably connected to the first guide rod; a lead screw motor mounted on the first lifting plate, and the lead screw of the lead screw motor is threadedly connected to the sliding seat; a sliding sleeve slidably connected to the sliding seat, and tooth holes are spacedly opened on the outer wall of the sliding sleeve; a marking pen placed inside the sliding sleeve; a fastening bolt threadedly connected to the sliding sleeve, and the end of the fastening bolt contacts the marking pen for fixing the marking pen; a second driving motor mounted on the sliding seat; a gear connected to the output shaft of the second driving motor, and the gear meshes with the tooth holes.

[0008] Further, the material taking component includes: a support frame connected to the mounting bracket; second guide rods symmetrically connected to both sides of the support frame; third electric push rods symmetrically mounted on both sides of the support frame; a second lifting plate slidably connected to the second guide rods, and the second lifting plate is connected to the telescopic rods of the third electric push rods; a first linear motor mounted on the bottom of the second lifting plate; a second linear motor mounted on the mover of the first linear motor; a second suction cup mounted on the mover of the second linear motor; a positioning mechanism arranged on the support frame for positioning the touch screen function sheets with abnormal functions in the placement frame.

[0009] Further, the positioning mechanism includes: a mounting rod connected to the top of the support frame; laser sensors spacedly mounted on the mounting rod.

[0010] Further, it also includes: a rotating rod symmetrically rotatably connected to the top of the fixed frame, and a slotted hole is opened at one end of the rotating rod; a double-acting cylinder mounted on the top of the fixed frame; a shifting rod respectively connected to the telescopic rods on both sides of the double-acting cylinder, and the end of the shifting rod is located in the slotted hole.

[0011] Further, it also includes: limit blocks symmetrically slidably connected to the inside of the fixed frame; connecting springs respectively connecting the limit blocks and the fixed frame at both ends.

[0012] Further, it also includes: rollers circumferentially and spacedly rotatably connected to the top of the turntable.

[0013] The beneficial effects are as follows: 1. Through the cooperation of the first electric push rod, the first suction cup and the turntable, the present invention can realize the automatic loading and unloading of the touch screen function chips, improve work efficiency. Specifically, by controlling the first electric push rod to drive the first suction cup to move back and forth through the controller, the automatic suction and release of the placement frame can be realized, and then combined with the intermittent rotation of the turntable, multiple fixed frames are sequentially located at the detection position, so as to realize the continuous automatic detection of the touch screen function chips. This structure can effectively reduce manual intervention, lower labor costs, and improve the test efficiency at the same time.

[0014] 2. Through the coordinated work of the connecting frame, the test contacts and the partition frame, the present invention can ensure the test accuracy of the test equipment. Specifically, during the test process, the first lifting plate drives the connecting frame and the test contacts to move downwards, so that the test contacts accurately contact the binding area of the touch screen function chip. At the same time, the partition frame limits multiple function chips to keep them in a vertical state, avoiding poor contact caused by inclination or misalignment. This multi-component linkage design can improve the test stability and accuracy, and ensure the reliability of the test results.

[0015] 3. Through the combined use of the marking mechanism and the laser sensor, the present invention can realize the automatic identification and rejection of defective products. Specifically, when the touch screen function chip test is completed, the lead screw motor drives the sliding seat to drive the marking pen to mark the marking area where the defective product is located. When the placement frame rotates to the lower part of the material taking component along with the turntable, the laser sensor locates the defective product according to the marking position, and guides the second suction cup to accurately take it out and classify the material. This system can realize the automatic identification and separation of defective products, avoid human operation errors, and improve the intelligent level of the overall detection process.

[0029] As Figure 7As shown in the figure, the material taking assembly includes a support frame 22, a second guide rod 23, a third electric push rod 24, a second lifting plate 25, a first linear motor 26, a second linear motor 27, a second suction cup 28 and a positioning mechanism. A support frame 22 is connected to the right side of the mounting bracket 1. The top of the support frame 22 is provided with an inclined surface. The right parts of the front and rear sides of the support frame 22 are both connected with a second guide rod 23. The left parts of the front and rear sides of the support frame 22 are both equipped with a third electric push rod 24. A second lifting plate 25 is slidably connected between the upper parts of the two second guide rods 23, and the second lifting plate 25 is connected to the telescopic rod of the third electric push rod 24. A first linear motor 26 is installed on the left side of the bottom of the second lifting plate 25. A second linear motor 27 is installed on the mover of the first linear motor 26. A second suction cup 28 is installed on the mover of the second linear motor 27. The second suction cup 28 is externally connected to an air pump through a connecting pipe. A positioning mechanism for positioning the malfunctioning touch screen function piece 003 in the placement frame 001 is provided on the support frame 22; the positioning mechanism includes a mounting rod 29 and a laser sensor 30. A mounting rod 29 is connected to the left side of the top of the support frame 22, and laser sensors 30 are installed at intervals from front to back on the mounting rod 29.

[0030] First, install the device at a specified position so that the device is located at the rear side of the conveyor, and then the placement frame 001 filled with the touch screen function pieces 003 can be Figure 10As shown (this is also the loading method in the existing processing factory), it is placed on the conveyor. The controller 2 controls the conveyor to intermittently convey the placement frame 001 filled with the touch screen function chips 003 to the right. When the placement frame 001 moves to the front of the fixed frame 5, the conveyor stops conveying the placement frame 001. At this time, the controller 2 will control the first electric push rod 6 on the front side to drive the first suction cup 7 on the front side to move forward, and control the first suction cup 7 on the front side to generate suction. When the first suction cup 7 on the front side contacts the placement frame 001, the first suction cup 7 on the front side will suck the placement frame 001. Subsequently, the controller 2 will control the first electric push rod 6 on the front side to drive the first suction cup 7 on the front side to move backward and reset. The first suction cup 7 on the front side will pull the placement frame 001 to move backward to the top of the turntable 3, and the placement frame 001 is located inside the fixed frame 5 on the front side. Then the controller 2 will control the first suction cup 7 on the front side to release the placement frame 001, and control the first driving motor 4 to drive the turntable 3 to rotate 90 degrees. The turntable 3 can drive the fixed frame 5 and the placement frame 001 thereon to rotate, so that the next fixed frame 5 rotates to the rear of the conveyor. Repeating the above operations can automatically load the placement frames 001 filled with the touch screen function chips 003 into the inside of each fixed frame 5 in sequence;When the placement frame 001 rotates with the turntable 3 to directly below the first lifting plate 10, the controller 2 will control the second electric push rod 9 to drive the first lifting plate 10 to move downward. The first lifting plate 10 drives the partition frame 11 and the connection frame 12 to move downward, so that the partition frame 11 and the connection frame 12 can be sleeved on the touch screen function chip 003 in the placement frame 001. At this time, the partition frame 11 and the connection frame 12 cooperate to limit each touch screen function chip 003, keeping the touch screen function chip 003 in a vertical state. Moreover, the test contact 13 in the connection frame 12 will contact the binding area 004 on the touch screen function chip 003. The test equipment can perform a function test on the touch screen function chip 003 through the test contact 13 and can feedback the test result data to the controller 2. The controller 2 can control the lead screw motor 16 to drive the sliding seat 15 to move left and right along the first guide rod 14 according to the test result data. The sliding seat 15 can drive the sliding sleeve 17 and the marker pen 18 to move left and right, so that the marker pen 18 moves to the same vertical plane as the malfunctioning touch screen function chip 003. Subsequently, the controller 2 will control the second driving motor 20 to drive the gear 21 to rotate. The gear 21 can drive the sliding sleeve 17 and the marker pen 18 to move obliquely downward through the engagement with the tooth hole 1701, so that the marker pen 18 can dot a white mark on the marking area 002 of the placement frame 001. Then the controller 2 will control the second driving motor 20 to drive the gear 21 to reverse. The gear 21 can drive the sliding sleeve 17 and the marker pen 18 to move obliquely upward to reset through the engagement with the tooth hole 1701. Subsequently, the controller 2 will control the second electric push rod 9 to drive the first lifting plate 10 to move upward to reset. The first lifting plate 10 drives the partition frame 11 and the connection frame 12 to move upward to reset, so that the partition frame 11 and the connection frame 12 are separated from the touch screen function chip 003;Then the placement frame 001 will rotate with the turntable 3 to directly below the mounting rod 29. At this time, each laser sensor 30 can detect the position of the white mark in the marking area 002 and feedback the detection data to the controller 2. The controller 2 can control the first linear motor 26 to drive the second linear motor 27 and the second suction cup 28 to move back and forth according to the detection data, so that the second suction cup 28 moves to directly above the front side of the malfunctioning touch screen function chip 003. Subsequently, the controller 2 will control the third electric push rod 24 to drive the second lifting plate 25 to move downward, driving the second suction cup 28 to move downward to the front side of the malfunctioning touch screen function chip 003, and control the second suction cup 28 to generate suction to hold the malfunctioning touch screen function chip 003. Then the controller 2 will control the third electric push rod 24 to drive the second lifting plate 25 to move upward to reset. The malfunctioning touch screen function chip 003 can be driven to move upward by the second suction cup 28 to disengage from the placement frame 001. Subsequently, the controller 2 will control the second linear motor 27 to drive the second suction cup 28 to move rightward to above the inclined surface of the support frame 22. Then the controller 2 will control the second suction cup 28 to release the malfunctioning touch screen function chip 003, so that the malfunctioning touch screen function chip 003 can fall onto the inclined surface and slide rightward along the inclined surface for discharging. At the same time, the controller 2 will control the second linear motor 27 to drive the second suction cup 28 to move leftward to reset; Subsequently, the placement frame 001 will rotate back to directly behind the conveyor with the turntable 3. At this time, the controller 2 will control the first suction cup 7 to move forward, pushing the placement frame 001 forward to the conveyor. The conveyor can convey the placement frame 001 containing the tested touch screen function chip 003 rightward for discharging, and the conveyor can convey the next placement frame 001 containing the touch screen function chip 003 to be tested rightward to the first suction cup 7. By repeating the above operations, the function tests of each touch screen function chip 003 can be automatically performed. At this time, with this device as the dividing line, the part of the conveyor on the left side of this device can automatically feed the placement frame 001 containing the touch screen function chip 003 to be tested, while the part of the conveyor on the right side of this device can automatically discharge the placement frame 001 containing the tested touch screen function chip 003.

[0031] As Figure 8 shown, it further includes a rotating rod 32, a double-acting cylinder 33 and a lever 34. Two rotating rods 32 are symmetrically and rotatably connected to the top of each of the four fixed frames 5. One end of the rotating rod 32 close to the opening of the fixed frame 5 is inclined outward. One end of the rotating rod 32 far from the opening of the fixed frame 5 is provided with a slotted hole 3201. Double-acting cylinders 33 are installed on the top of each of the four fixed frames 5. A lever 34 is connected to the telescopic rods on both sides of the double-acting cylinder 33. The levers 34 correspond to the slotted holes 3201 one by one, and the end of the lever 34 is located in the slotted hole 3201.

[0032] When the conveyor transports the placement frame 001 to the front of the fixed frame 5, the controller 2 can first control the bidirectional cylinder 33 to drive the lever 34 on both sides to move away from each other. The lever 34 can drive the rotating rod 32 to rotate through the cooperation with the one-hole 3201, so that the end of the rotating rod 32 close to the opening of the fixed frame 5 moves closer to each other. When the end of the rotating rod 32 contacts the placement frame 001, it can push the placement frame 001 to move and center and straighten. Subsequently, the controller 2 will control the bidirectional cylinder 33 to drive the lever 34 on both sides to move closer to each other and reset. The lever 34 can drive the rotating rod 32 to reverse and reset, so that the end of the rotating rod 32 is separated from the placement frame 001. Subsequently, the controller 2 will control the first suction cup 7 to move forward to suck the placement frame 001, and then control the first suction cup 7 to pull the placement frame 001 to move backward for automatic feeding. Through the centering function of the rotating rod 32, it is ensured that the placement frame 001 can accurately enter the inside of the fixed frame 5.

[0033] As Figure 8 shown, it also includes a limit block 35 and a connecting spring 36. Two limit blocks 35 are symmetrically and slidably connected to the inner side of the opening of each of the four fixed frames 5. The inner sides of the two limit blocks 35 close to each other are arc surfaces. A connecting spring 36 is connected between the outer sides of the two limit blocks 35 away from each other and the fixed frame 5. When the first suction cup 7 pulls the placement frame 001 to move backward into the inside of the fixed frame 5, the placement frame 001 will squeeze the limit blocks 35 on both sides to move away from each other, and the connecting spring 36 will be compressed. When the placement frame 001 completely enters the inside of the fixed frame 5, the placement frame 001 will be separated from the limit block 35. At this time, the connecting spring 36 will return to its original state, driving the limit blocks 35 on both sides to move closer to each other and reset, so that the limit blocks 35 block the front side of the placement frame 001, thereby being able to limit the placement frame 001. During the rotation of the placement frame 001 with the turntable 3, it can prevent the placement frame 001 from moving.

[0034] As Figure 9 shown, it also includes a roller 37. A plurality of rollers 37 are rotatably connected at intervals on the front, back, left, and right sides of the top of the turntable 3, and the roller 37 is located inside the fixed frame 5. The roller 37 can reduce the friction between the bottom of the placement frame 001 and the top of the turntable 3, facilitating the movement, feeding, and discharging of the placement frame 001.
