Description

Technical Field

[0001] The invention relates to a terminal detection device, in particular to an automatic terminal strip detection machine. Background Art

[0002] The description in this section merely provides background information related to the present disclosure and does not constitute prior art.

[0003] Terminals need to be inspected before leaving the factory to determine whether they meet the factory requirements for use. If not, a detection device is required to mark the defective terminals. The terminals are generally connected in a string through material strips, and the terminal material strips are subsequently cut.

[0004] In the existing cutting step after the inspection of the terminal strip, due to the force on the cutting edge of the strip after cutting, the cutting edge of the strip may be slightly deformed, which often easily causes the terminal strip to be stuck in the hollow area during subsequent transportation, affecting the inspection efficiency of the terminal. At the same time, the layout of the existing inspection mechanism for the terminal strip is unreasonable, and it is impossible to meet the requirements of fast inspection, cutting, and welding in an entire production line.

[0005] Currently, there is no terminal strip automatic inspection machine that can solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide an automatic terminal strip inspection machine, which can slightly lift the terminal strip to avoid material jamming by arranging a baffle with a raised portion in a hollow area used for cutting.

[0007] In order to achieve the above-mentioned object, the present invention discloses the following terminal material strip automatic detection machine, which is used for detecting terminal material strips, wherein the terminal material strip comprises a terminal and a material strip, the terminal and the material strip are connected, the number of the terminal material strips is multiple, the multiple terminal material strips are connected in series through their respective material strips, and each of the material strips is provided with a positioning hole; the terminal material strip automatic detection machine comprises:

[0011] A welding mechanism, the welding mechanism is arranged downstream of the cutting mechanism on the conveying table, the welding mechanism comprises a laser welder, and the laser welder is arranged toward the position on the conveying table where the material strip is cut;

[0012] The baffle has a protrusion, so that when the baffle moves to the hollow area, the terminal strip passing through the hollow area can be lifted by the baffle to a level higher than the conveying platform.

[0013] Furthermore, the cutting mechanism also includes a cutting positioning part, which is transmission-connected to the cutting cylinder, and the cutting positioning part is arranged in the direction of the positioning hole of the material strip at the corresponding position of the hollow area, so that before the cutting knife cuts the material strip at the corresponding position, the cutting positioning part first positions the material strip at the corresponding position.

[0014] Furthermore, the welding mechanism includes a welding cover, which is arranged on the conveying table. The welding cover has a welding hole on it, and the welding hole is arranged between the conveying table and the laser welder, so that the laser welder can and only can process the area at the bottom of the welding hole by laser.

[0015] Furthermore, the conveying mechanism has a plurality of conveying rollers, one of which is disposed upstream of the cutting mechanism on the conveying platform, and another of which is disposed downstream of the cutting mechanism on the conveying platform.

[0016] Furthermore, after the cutting is completed, the conveying roller arranged upstream of the conveying platform of the cutting mechanism first transports the multiple terminal material strips downstream, and the conveying roller arranged downstream of the conveying platform of the cutting mechanism then transports the multiple terminal material strips downstream, so that the two upstream and downstream sections of the terminal material strips can be reconnected together.

[0017] Furthermore, it also includes a waste trough, which is connected to the hollow area and is used to collect the terminal strip cut at the hollow area.

[0018] Furthermore, the cutting blade of the cutting mechanism can cut a plurality of the terminal strips at the same time.

[0019] Furthermore, the positioning teeth of the conveying roller can contact with a plurality of the terminal strips at the same time.

[0020] By means of the above technical solution, the beneficial effects of the present invention are as follows:

[0021] The automatic terminal strip inspection machine of the present invention can be configured with a baffle having a raised portion in a hollow area used for cutting. When the corresponding terminal strip is transported to the hollow area and cut, the baffle can be quickly filled to the position of the hollow area, so that the conveying platform of the hollow area is repaired, and the terminal strip can continue to be pushed through the hollow area by the conveying roller. At the same time, the corresponding terminal strip passing through is slightly lifted, avoiding the situation where the terminal strip is stuck by the conveying platform of the hollow area due to deformation after cutting, thereby indirectly improving the inspection efficiency of the present invention.

[0032] See also Figure 1-4, is an automatic terminal strip inspection machine of the present embodiment, used for inspecting a terminal strip 100, wherein the terminal strip 100 includes a terminal 101 and a strip 102, the terminal 101 and the strip 102 are connected, the number of the terminal strips 100 is multiple, the multiple terminal strips 100 are connected in series through their respective strips 102, and each strip 102 is provided with a positioning hole; wherein the automatic terminal strip inspection machine includes:

[0033] The conveying mechanism 1 includes a conveying platform 11 and a conveying roller 12. The conveying platform 11 extends in the upstream and downstream directions. The conveying platform 11 is used to place a plurality of terminal strips 100 connected in series. The conveying roller 12 is arranged adjacent to the conveying platform 11. The conveying roller 12 includes a positioning tooth matching the positioning hole, and the positioning tooth is arranged in the direction of the positioning hole, so that when the conveying roller 12 rotates, the plurality of terminal strips 100 connected in series can be pushed to move downstream of the conveying platform 11.

[0034] A detection mechanism 2, which is disposed upstream of the conveying platform 11 and is disposed toward the conveying platform 11, and is used to identify the quality of the passing terminal 101 and perform calibration;

[0035] The cutting mechanism 3 is arranged at the downstream of the detection mechanism 2 on the conveying platform 11. The conveying platform 11 has a hollow area 111 at the position of the cutting mechanism 3. The cutting mechanism 3 includes a cutting knife 31, a cutting cylinder 32, a baffle 33, and a baffle cylinder 34. The cutting cylinder 32 is connected to the cutting knife 31 by transmission. The cutting cylinder 32 is used to drive the cutting knife 31 to reciprocate vertically in the direction of the hollow area 111. The baffle cylinder 34 is connected to the baffle 33 by transmission. The baffle cylinder 34 is used to drive the baffle 33 to reciprocate horizontally. The terminal strip 100 reciprocates in the direction of the hollow area 111. When the terminal 101 marked as a defective product passes through the hollow area 111, the cutting cylinder 32 drives the cutting knife 31 to cut downward, so that the material strip 102 at the corresponding position is cut and falls from the hollow area 111. When the terminal 101 marked as a good product passes through the hollow area 111, the baffle cylinder 32 drives the baffle 33 to move to the hollow area 111 to provide support for the terminal material strip 100, so that the terminal material strip 100 can continue to be pushed to the downstream of the conveyor 11;

[0036] A welding mechanism 4, which is arranged downstream of the cutting mechanism 3 on the conveying table 11, and includes a laser welder 41, which is arranged toward the position where the material strip 102 on the conveying table 11 is cut;

[0037] The baffle plate has a protrusion 331 , so that when the baffle plate 33 moves to the hollow area 111 , the terminal strip 100 passing through the hollow area 111 can be lifted by the baffle plate 33 to a level higher than the conveying platform 11 .

[0038] Through the above structure, when in use, the operator only needs to place a sufficient amount of terminal strips 100 to be inspected on the conveyor 11 from the upstream of the conveyor 11 in a preset order and angle, and make the positioning holes of the upper strip 102 of at least one of the terminal strips 100 be clamped by the positioning teeth of the conveyed roller 12, and then the conveyor roller 12 can be started to rotate. During the rotation of the conveyor roller 12, the positioning teeth of the conveyor roller 12 can push the positioning holes of the strip 102, so that multiple terminal strips 100 are pushed downstream of the conveyor 11. First, when the terminal strip 100 passes through the detection mechanism 2 upstream of the conveyor 11, the detection mechanism 2 calibrates the quality of the terminal 101 passing through, mainly to calibrate the defective terminal 101, and then sends a signal to the external control mechanism. After the terminal 101 marked as a defective product passes through the downstream cutting mechanism 3, the control mechanism controls the conveying roller 12 to stop pushing the terminal strip 100, and the corresponding terminal strip 100 is suspended in the hollow area 111, and the cutting mechanism 3 is started to operate. The cutting knife 31 of the cutting mechanism 3 is driven by the cutting cylinder 32 to cut downward, so that the edges of the two ends of one or more defective terminal strips 100 that need to be cut are cut by the cutting knife 31, and the terminal strips 100 cut at both ends fall from the hollow area 111 and are collected. Then, the baffle cylinder 34 drives the baffle 33 to quickly fill the hollow area 111, so that the subsequent upstream terminal strip 100 can be supported at the hollow area 111, and the conveying roller 12 starts to run again. The upstream terminal strip 100 passes through the hollow area 111 with the support of the baffle 33 and reaches the downstream welding mechanism 4. The conveying roller 12 stops pushing the terminal strip 100 again, and the laser welder 41 of the welding mechanism 4 welds the cut part of the terminal strip 100, so that the multiple terminal strips 100 cut off upstream and downstream are reconnected together, and then, the conveying roller 12 continues to push the multiple welded terminal strips 100 downstream until they fall into the designated good product collection area.

[0039] In the above-mentioned use process, since the baffle 33 with the protrusion 331 is provided in the hollow area 111 for cutting, when the corresponding terminal strip 100 is transported to the hollow area 111 and cut, the baffle 33 can be quickly filled to the position of the hollow area 111, so that the conveying platform 11 of the hollow area 111 is repaired, so that the terminal strip 100 can continue to be pushed through the hollow area 111 by the conveying roller 12, and at the same time, the corresponding terminal strip 100 passing through is slightly lifted, avoiding the terminal strip 100 being cut after being cut. The deformation causes the terminal strip 100 to be stuck by the conveying platform 11 in the hollow area 111. Specifically, in this embodiment, the height of the baffle 33 of the protrusion 331 is about 1 mm higher than the horizontal height of the conveying platform 11, and the upstream and downstream ends of the protrusion 331 have a certain arc transition, so that the terminal strip 100 can be smoothly lifted slightly, and at the same time, with the help of the front and rear arc transition of the protrusion 331, it can pass through the baffle 33 stably without being hindered by the L-angle section of the conveying platform 11 at both ends.

[0040] Of course, in some other embodiments, the lifting height of the protrusion 331 can be adjusted according to the deformation trend of the terminal strip 100 after being cut. If the amount of deformation is large, the height of the protrusion is higher to avoid being stuck by the conveying platform 11. If the amount of deformation is small, the height of the protrusion is smaller to avoid the jamming phenomenon caused by the protrusion being too high.

[0041] Furthermore, the cutting mechanism 3 also includes a cutting positioning part 35, which is in driving connection with the cutting cylinder 32, and is arranged toward the positioning hole direction of the material strip 102 at the corresponding position of the hollow area 111, so that before the cutting knife 31 cuts the material strip 102 at the corresponding position, the cutting positioning part 35 first positions the material strip 102 at the corresponding position. In other words, the cutting positioning part 35 connected to the cutting cylinder 32 has a longer length, and before cutting, the cutting positioning part 35 first contacts with the terminal material strip 100, and first accurately positions the terminal material strip 100, and then, the cutting knife 31 cuts the material strip 102, and through the above structure, the cutting of the terminal material strip 100 is more accurate.

[0042] Furthermore, the welding mechanism 4 includes a welding cover 42, which is disposed on the conveying platform 11. The welding cover 42 has a welding hole 421 thereon, and the welding hole 421 is disposed between the conveying platform 11 and the laser welder 41, so that the laser welder 41 can and can only process the area at the bottom of the welding hole 421 by laser. By setting the welding cover 42 as described above, it is possible to avoid the influence of excessive welding on the connection between the terminal 101 of the terminal strip 100 due to the difficulty in stabilizing the power of the laser welder 41, thereby avoiding waste.

[0043] Furthermore, the number of the conveying rollers 12 of the conveying mechanism 1 is multiple, one of which is arranged upstream of the cutting mechanism 3 on the conveying platform 11, and the other is arranged downstream of the cutting mechanism 3 on the conveying platform 11. Specifically, after the cutting is completed, the conveying roller 12 arranged upstream of the cutting mechanism 3 on the conveying platform 11 first transports the multiple terminal strips 100 downstream, and the conveying roller 12 arranged downstream of the cutting mechanism 3 on the conveying platform 11 then transports the multiple terminal strips 100 downstream, so that the two sections of the terminal strips 100 upstream and downstream can be reconnected. The purpose of the above-mentioned structure is to avoid the existence of a gap between the upstream terminal strip 100 and the downstream terminal strip 100 after cutting, and the upstream and downstream of the terminal strip 100 are each provided with an independent conveying roller 12, so that the upstream and downstream can independently and flexibly control the position of each section of the multiple terminal strips 100 after cutting, so as to facilitate the subsequent welding operation.

[0044] Of course, in this embodiment, a conveying roller 12 is also included at the uppermost part of the conveying platform 11, so that only a small amount of terminal strips 100 can be placed, and all the terminal strips 100 can be directly pushed downstream.

[0045] For further information, see Figure 1 , and further includes a waste trough 5, which is connected to the hollow area 111 and is used to collect the terminal strips 100 cut at the hollow area 111. Specifically, the waste trough 5 is configured as a multi-section bent pipe-like structure, and the first end of the pipe is connected to the bottom of the hollow area 111, so that the defective products after cutting directly fall into the waste trough 5 by their own weight, and are guided to the preset waste collection place to avoid accumulation affecting the cutting operation of other terminal strips 100 in this embodiment.

[0046] For further information, see Figure 2 , the cutting blade 31 of the cutting mechanism 3 can cut a plurality of terminal strips 100 at the same time. Specifically, in this embodiment, the cutting blade 31 has a preset width, and can simultaneously cut two terminal strips 100, so that an outer edge of each of the two terminal strips 100 is cut off. Of course, the number of cuts in one cut can be adjusted according to actual processing needs.

[0047] Furthermore, the positioning teeth of the conveying roller 12 can contact multiple terminal strips 100 at the same time. That is to say, the conveying roller 12 in this embodiment has a larger diameter, and the positioning teeth also have a sufficient length, so that the conveying roller 12 can move multiple terminal strips 100 at the same time, making the conveying roller 12 push the terminal strips 100 more stable.
