Description

Technical Field

[0001] The invention relates to the technical field of sensor harness production, in particular to a board marking and blanking module. Background Art

[0002] The sensor harness is an electrical harness specially used to connect sensors. It is mainly used to connect the sensor to the controller to transmit and receive the sensor's measurement signal of physical quantities. The sensor and the harness are welded together through a welding device. During welding, multiple harnesses are arranged on the board, and then the harnesses placed on the board are pasted together with the board through tape. The arranged harnesses are then transported to the conveyor chain in the welding device and the welding is completed. After welding, the tape on the board is sprayed with a code through a marking device to facilitate the subsequent identification of sensor harness models. After marking, the multiple sets of sensor harnesses on the board and tape are placed in the placement rack through the unloading device to complete the unloading.

[0003] In the prior art, the conveyor chain on the marking blanking module is used to convey the board and the multiple wire harnesses and tape on the board to the bottom of the inkjet printer to perform coding marking on the tape. However, the tape pasted on the board and the multiple wire harnesses may have some protrusions or unevenness. At this time, not only the words on the tape after coding are difficult to see clearly, which will affect the coding and marking effect of the tape, but also the viscosity of the tape is affected, resulting in the problem of reduced adhesion between the tape and the wire harness and the board.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The flattening mechanism of the present invention can flatten the raised or uneven tape on the board body through the L-shaped plate on the pressure wheel before the conveyor chain drives the board body and the tape to move and transport to the position below the inkjet printer, thereby increasing the flatness of the tape. The words on the tape can be clearly seen after the subsequent inkjet printer sprays the code, thereby improving the marking effect of the tape. Moreover, after the tape is flattened, the adhesion strength between the tape and the wire harness and the board body can be increased, thereby improving the fixing strength of the wire harness.

[0018] (2) The present invention is designed with a blowing part. When the conveying chain drives the plate body, tape, etc. to be transported, air is blown toward the passing tape through the blowing nozzle on the tube body. The wind force blows away the dust attached to the surface of the tape, making it easier for the tape to enter the bottom of the inkjet printer for marking. The possibility of unclear words on the tape after marking and affecting the marking quality due to the influence of dust on the surface of the tape during the marking process is reduced, thereby improving the marking quality of the tape.

[0019] (3) The present invention has a designed limiter which can limit the main body of the board when the moving tape is rolled flat by the rubber wheel, thereby preventing the main body of the board from tilting up when the tape contacts the rolling of the rubber wheel. The main body of the board is limited by the left and right limiter strips, thereby increasing the stability of the main body of the board and the tape during the inkjet marking process.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1

[0035] See also Figure 1-Figure 10 The present invention provides a technical solution: a board marking blanking module, comprising a machine body 100, a bracket 101 installed on the top of the machine body 100 and a blanking component located on one side of the machine body 100, a coding seat 103 is arranged on the bracket 101, a coding machine 102 is fixedly arranged at the bottom of the coding seat 103, a conveying chain 111 is rotatably arranged on the top of the machine body 100, a board body 112, a wiring harness and a tape 114 can be moved and conveyed by the conveying chain 111, a board body 112 is arranged on the top of the conveying chain 111, a plurality of wiring harnesses and tapes 114 are respectively arranged on the top of the board body 112, the wiring harness and the tapes 114 can be pasted together by the tapes 114, a flattening mechanism for flattening the tapes 114 is arranged on the coding machine 102, and the flattening mechanism includes a lifting component and a flattening component;

[0036] The flattening assembly includes a limit plate 200 and multiple groups of pressure wheels 209, the outer sleeve of the pressure wheel 209 is fixed with a rubber wheel 204, both ends of the pressure wheel 209 are rotatably provided with T-shaped columns 212, the T-shaped columns 212 are provided with connecting plates 213, the top of the connecting plate 213 is fixedly provided with an L-shaped plate 214, the side of the L-shaped plate 214 is fixedly provided with a T-shaped slide rail 216, the top of the limit plate 200 and along the length direction of the limit plate 200 are evenly distributed with multiple groups of mounting rails 210, the T-shaped slide rail 216 can slide up and down in the mounting rail 210, and the top of the T-shaped slide rail 216 penetrates into the interior of the mounting rail 210;

[0037] An upper plate 211 is fixedly arranged on one side of the top of the mounting track 210, and a bottom plate 215 is fixedly arranged on the other side of the top of the L-shaped plate 214. A spring 217 is fixedly arranged between the upper plate 211 and the bottom plate 215. During use, the spring 217 can continuously generate a downward force on the pressing wheel 209, thereby increasing the flattening effect of the rubber wheel 204 outside the pressing wheel 209 on the adhesive tape 114 on the board body 112.

[0038] The lifting assembly includes a vertical track 201 installed on one side of the inkjet printer 102, a T-shaped slide plate 218 is slidably arranged on the vertical track 201, and the T-shaped slide plate 218 can slide up and down in the vertical track 201, a vertical plate 207 is fixedly arranged on the side of the T-shaped slide plate 218, the bottom of the vertical plate 207 is fixed to the top of the limit plate 200, and a triangular reinforcement plate is fixedly arranged between the vertical plate 207 and the limit plate 200;

[0039] A middle plate 206 is fixedly provided on the top side of the vertical plate 207, a side plate 202 is fixedly provided on the top side of the vertical track 201, and a driving hydraulic rod 205 is fixedly provided on the bottom of the side plate 202. The vertical plate 207, the limit plate 200, etc. can be moved downward by driving the hydraulic rod 205, and the working end of the driving hydraulic rod 205 is fixedly connected to the middle plate 206.

[0040] The present invention is designed with a smoothing mechanism. During use, when the conveying chain 111 drives the board body 112 and the tape 114 to move and convey them to the position below the inkjet printer 102, the rubber wheel 204 on the pressure wheel 209 flattens the raised or uneven tape 114 on the board body 112, thereby increasing the flatness of the tape 114. The words on the tape 114 after the subsequent inkjet printer 102 sprays the code can be clearly seen, thereby improving the marking effect of the tape 114. Moreover, after the tape 114 is flattened, the adhesion firmness between the tape 114 and the wiring harness and the board body 112 can be increased, thereby improving the fixing firmness of the wiring harness.

[0041] During use, the driving hydraulic rod 205 is first turned on, and the driving hydraulic rod 205 drives the middle plate 206, the vertical plate 207, the T-shaped slide plate 218 and the lower limit plate 200 to descend. At this time, the T-shaped slide plate 218 slides in the vertical track 201, and stops descending when it moves to a suitable position. Before the conveying chain 111 drives the plate body 112 and the tape 114 to move into the position below the inkjet printer 102, the tape 114 will first contact the pressure wheel 209. The external rubber wheel 204, the rubber wheel 204 and the pressure wheel 209 begin to roll the tape 114. During the rolling process, the spring 217 is squeezed by the rubber wheel 204 and begins to compress, thereby increasing the rolling effect on the tape 114. During the rolling process, the T-shaped slide rail 216 located on the L-shaped plate 214 will slide up and down in the mounting track 210, and the rotating pressure wheel 209 and the rubber wheel 204 can flatten the raised or uneven tape 114.

[0042] Example 2

[0043] Based on Example 1, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 The end of the limit plate 200 is provided with a purge member for removing dust attached to the surface of the adhesive tape 114. The purge member includes a connecting pipe 402 embedded in the limit plate 200, and one end of the connecting pipe 402 extends to the outside of the limit plate 200. A tube body 400 is fixedly provided at one end of the connecting pipe 402, and a plurality of blowing nozzles 403 are fixedly provided on the tube body 400.

[0044] A blower 401 is fixedly installed on the side of the vertical plate 207. The wind generated by the blower 401 is transmitted to the tube body 400 through the lower tube 404 and the connecting tube 402. The lower tube 404 is fixedly installed at the bottom of the blower 401, and the end of the lower tube 404 is fixedly connected to the other end of the connecting tube 402.

[0045] The present invention uses a designed blowing piece. When the conveying chain 111 drives the plate body 112, the tape 114, etc. to be conveyed, the blowing nozzle 403 on the tube body 400 blows air toward the passing tape 114, so that the dust attached to the surface of the tape 114 is blown off by the wind force, so that the tape 114 can enter the bottom of the inkjet printer 102 for marking, thereby reducing the possibility of unclear words on the tape 114 after inkjet printing and affecting the marking quality due to the influence of dust on the surface of the tape 114 during the inkjet printing process, thereby improving the marking quality of the tape 114.

[0046] During use, the blower 401 is turned on, and the blowing nozzle 403 on the tube body 400 blows air downward through the blower 401. When the conveying chain 111 drives the board body 112 and the tape 114 to move through the blowing nozzle 403, some dust attached to the surface of the tape 114 will be blown away by the wind, reducing the influence of the dust attached to the surface of the tape 114 on the subsequent inkjet marking of the tape 114.

[0047] Example 3

[0048] Based on Example 2, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Fig.10 , Fig.11 and Fig.12The end of the tube body 400 and the side of the inkjet printer 102 are provided with a limiting member for limiting the plate body 112 and the adhesive tape 114. The limiting member includes an L-shaped frame 300 installed at the end of the tube body 400 and an L-shaped block 306 installed at the side of the inkjet printer 102. A vertical bar 303 is slidably provided inside the L-shaped frame 300. A first locking stud 304 is threadedly connected inside the L-shaped frame 300. The vertical bar 303 can be fixed by the first locking stud 304, and the working end of the first locking stud 304 extends to the surface of the vertical bar 303. A left limiting bar 301 is fixedly provided at the bottom of the vertical bar 303. The plate body 112 can be limited by the left limiting bar 301 and the right limiting bar 302 to avoid warping.

[0049] A mounting frame 305 is arranged outside the L-shaped block 306, and a second locking stud 307 is threadedly connected inside the mounting frame 305. The second locking stud 307 can fix the mounting frame 305, and the working end of the second locking stud 307 extends to the surface of the L-shaped block 306. A right limiting strip 302 is fixedly arranged at the bottom of the mounting frame 305.

[0050] The present invention uses a designed limiter to limit the board body 112 when the moving tape 114 is rolled flat by the rubber wheel 204, thereby preventing the board body 112 from tilting up when the tape 114 on the board body 112 contacts the rolling of the rubber wheel 204. The board body 112 is limited by the left limit strip 301 and the right limit strip 302, thereby increasing the stability of the board body 112 and the tape 114 during the inkjet marking process.

[0051] When in use, the heights of the left and right limiting strips 301, 302 are adjusted according to the heights of the plate body 112, the wiring harness and the adhesive tape 114. When adjusting the height of the left limiting strip 301, the first locking stud 304 is turned outward to loosen it, and then the vertical bar 303 is moved upward or downward, thereby driving the left limiting strip 301 to move. When the adjustment is completed, the first locking stud 304 is tightened; when adjusting the height of the right limiting strip 302, the second locking stud 307 is turned outward to loosen it, and then the mounting bracket 305, the right limiting strip 302 and the mounting bracket 305 are turned outward to loosen it. After the limiting strip 302 moves upward or downward to a suitable position, the second locking stud 307 is tightened. When the moving board body 112 and the adhesive tape 114 contact the rubber wheel 204 and appear to be tilted, they are blocked and limited by the left limiting strip 301. After the coding is completed, it moves to the position below the right limiting strip 302. At this time, the rubber wheel 204 is separated from the left side of the board body 112 and the adhesive tape 114. When the board body 112 appears to be tilted, it will be blocked and limited by the right limiting strip 302.

Two groups of supporting plates 109 are fixedly provided on the bottom of the track frame 104, and a placement frame 106 is fixedly provided on the surface of the supporting plate 109.

[0054] After the tape 114 is marked, the slider on the back of the lifting rod 105 moves to the left to the position above the board body 112 located at the top of the conveying chain 111, and then the hydraulic cylinder 107 and the double-headed cylinder 108 are lowered by the action of the lifting rod 105, and then the double-headed cylinder 108 is opened to drive the two sets of clamping plates 115 to move in opposite directions, and then the board body 112 can be clamped, and then the lifting rod 105 drives the board body 112 to rise, and then moves to the right side to the specified position through the slider, and then the hydraulic cylinder 107 is opened, and the working end of the hydraulic cylinder 107 moves downward, driving the rotating plate 117 to rotate 90 degrees around the rotating shaft frame 118, and then driving the board body 112 to turn over.
