[0063] a transmission support 1; a pair of driven members 2 movably installed on the transmission support 1; a pair of side hangers 3 movably installed on the transmission support 1, and used for suspending a target workpiece 20; and a hanger adjusting device installed on the transmission support 1, and used for driving the pair of side hangers 3 to perform synchronous translation movement towards or away from each other and changing the interval of the pair of side hangers 3.

[0064] The transmission hanger adjusting structure provided by the application drives the pair of side hangers 3 to perform synchronous translation movement towards or away from each other through the same hanger adjusting device, so as to meet the requirement of synchronous (equidistance) telescopic adjustment of the two sides of the hanger, and the layout is relatively simple and the components are less, thereby improving the versatility of the transmission hanger and controlling the cost.

[0065] Please refer to Figures 1-6 In the first embodiment of the transmission hanger adjusting structure, the hanger adjusting device comprises:

[0066] a pair of driven members 2 movably installed on the transmission support 1, and provided with driven racks 21; a pair of side hangers 3 connected to the pair of driven members respectively; a driving gear 4 rotatably installed on the transmission support 1 and located between the pair of driven members 2, and engaged with the corresponding driven racks 21 of the pair of driven members 2 respectively; and a rotary driving device (not shown in the figure) installed on the transmission support 1, and used for driving the driving gear 4 to perform rotary movement, so as to drive the corresponding driven racks 21 of the pair of driven members 2 to perform synchronous translation movement towards or away from each other through the rotary movement of the driving gear 4, and further drive the pair of driven members 2 to perform synchronous translation movement towards or away from each other, and change the interval of the pair of side hangers 3. The rotary driving device is preferably a driving motor or a rotary cylinder.

[0067] The transmission hanger adjusting structure in the embodiment drives the driving gear 4 to drive the pair of driven members 2 to perform synchronous translation movement towards or away from each other through the same rotary driving device, so as to meet the requirement of synchronous (equidistance) telescopic adjustment of the two sides of the hanger, improve the size adjustment effect of the transmission hanger, make the layout of the transmission hanger adjusting structure relatively simple and the components less, and further improve the versatility of the transmission hanger and control the cost.

[0068] In other embodiments of the transmission hanger adjusting structure (not shown in the drawings), the hanger adjusting device can also adopt a motor-driven synchronous pulley mechanism, which drives the belt or toothed belt to rotate, so that the up-and-down belt bodies of the belt or toothed belt move synchronously towards or away from each other, and then a pair of driven members 2 connected to the up-and-down belt bodies of the belt or toothed belt move synchronously towards or away from each other, thereby synchronously adjusting the two sides of the hanger.

[0071] When the pair of driven members 2 move synchronously towards or away from each other under the rotation of the driving gear 4, the pair of bottom hangers 6 are driven by the pair of electrically conductive connecting members 5 to move synchronously towards or away from each other along the guide bottom frame 7, so that the transmission hanger adjusting structure simultaneously realizes synchronous expansion and contraction adjustment of the upper and lower sides of the hanger, and further improves the adjustment effect. In addition, the up-and-down connection of the pair of side hangers 3 and the pair of bottom hangers 6 through the pair of electrically conductive connecting members 5 can keep the adjustment of the upper and lower sides of the hanger synchronous, and ensure that the upper and lower hangers do not jam.

[0076] Please refer to Figures 1-3 , 6-9, in the preferred embodiment of the first embodiment of the transmission hanger adjusting structure, the transmission hanger adjusting structure further comprises:

[0077] A pair of limiting devices 9 are installed on the installation vertical plate 12 in a spaced manner, and a pair of limiting devices 9 are respectively located between the driving gear 4 and the pair of guide seats 8, for limiting the stroke of the pair of driven rods (driven members 2) moving synchronously away from each other to define the synchronous (equidistant) extension distance on both sides of the hanger, so that the transmission hanger adjusting structure can adjust the distance between the pair of side hangers 3 to a certain preset range according to the actual application scene, avoiding that the distance between the pair of side hangers 3 is too small or too large.

[0078] Please refer to Figures 1-3 , 6-9, in the preferred embodiment of the first embodiment of the transmission hanger adjusting structure, the limiting device 9 comprises:

[0079] A reset adjusting mechanism 91 is installed on the installation vertical plate 12 and located between the driving gear 4 and the corresponding guide seat 8, for adjusting the distance between the limiting member 92 and the driving gear 4; the above-mentioned limiting member 92 is used for cooperating with the driven rod (driven member 2) or the driving gear 4 to limit the stroke of the pair of driven rods (driven members 2) moving synchronously.

[0080] Please refer to Figures 1-3 , in the first embodiment of the transmission hanger adjusting structure, the reset adjusting mechanism 91 is a first reset member 913 which resets by using elastic force or a reset adjusting mechanism 91 which resets by driving with the on-off electricity of electromagnet, and the limiting member 92 is a limiting block which cooperates with the driven rack 21 on the driven rod (driven member 2) (i.e. is arranged on the reciprocating translation track of the driven rack 21).

[0082] Please refer to Figures 7-9In the preferred embodiment of the first embodiment of the transmission hanger adjusting structure, the first reset member 913 is a first reset spring, and the reset adjusting mechanism 91 comprises:

[0083] The spring mounting seat 911 is mounted on the mounting stand 12 and located between the driving gear 4 and the corresponding guide seat 8. The first reset guide rod 912 is movably horizontally arranged on the spring mounting seat 911, and one end of the first reset guide rod 912 extends in the horizontal direction close to the driving gear 4. The limiting block (limiting member 92) is arranged at the end of the first reset guide rod 912 close to the driving gear 4. The first reset spring (first reset member 913) is sleeved on the first reset guide rod 912 and abuts against the spring mounting seat 911, and is used to reset the first reset guide rod 912 to extend close to the driving gear 4, so that the position of the limiting tooth 921 of the limiting block (limiting member 92) is reset to the preset distance relative to the driving gear 4. At the same time, the first reset spring (first reset member 913) can play a certain buffering role when the limiting block (limiting member 92) and the limiting groove 41 of the driving gear 4 are in abutting cooperation.

[0084] When the driving gear 4 rotates in the forward and reverse directions to the two sides of a pair of limiting grooves 41, respectively abutting and cooperating with the corresponding side of the limiting tooth 921 of the corresponding limiting block (limiting member 92), the stroke of the synchronous opposite or opposite translation movement of the pair of driven rods (driven members 2) can be limited to the preset extension (opening) or retraction (folding) distance.

[0085] Please refer to Figures 7-9 In the preferred embodiment of the first embodiment of the transmission hanger adjusting structure, a ratchet wheel is coaxially arranged on the back surface of the driving gear 4, and a pair of limiting grooves 41 are arranged relative to the axis of the ratchet wheel.

[0086] Through the abutting cooperation of the pair of limiting grooves 41 on both sides of the ratchet wheel and the limiting tooth 921 of the limiting block (limiting member 92) on the corresponding side under the pushing of the first reset spring (first reset member 913), the stroke of the synchronous opposite or opposite translation movement of the pair of driven rods (driven members 2) can be locked at any extension (opening) or retraction (folding) distance, thereby ensuring the stability of the pair of side hangers 3 and the pair of bottom hangers 6 suspending the target workpiece 20.

[0088] In other embodiments of the first embodiment of the transmission hanger adjusting structure, the limiting block (limiting member 92) does not need to be provided with the limiting protruding teeth 921, and the first reset spring (first reset member 913) is used to reset the first reset guide rod 912 to extend close to the driving gear 4, so that the position of the limiting block (limiting member 92) is reset to the preset distance relative to the driving gear 4, and the preset position of the limiting block (limiting member 92) is located on the movement path of the driven rack 21 of the driven rod (driven member 2) or other limiting structures provided on the driven rod (driven member 2).

[0089] When the driving gear 4 rotates forward and backward to abut the pair of driven racks 21 or other limiting structures provided on the driven rod (driven member 2) and the corresponding limiting block (limiting member 92), the stroke of the pair of driven rods (driven members 2) in the synchronous opposite or opposite translation movement can be limited to the preset extension (opening) or retraction (folding) distance.

[0090] Please refer to Figures 1-3 In the first embodiment of the transmission hanger adjusting structure, it further includes:

[0091] The first buffer mechanism 81 is connected between the side hanger 3 and the outer side of the guide seat 8 away from the driving gear 4, and enhances the stability of the transmission hanger adjusting structure when the driving gear 4 drives the pair of driven racks 21 (driven members 2) to move close to (fold) or away from (open) synchronously, and provides buffer for the target workpiece 20.

[0092] Please refer to Figures 1-3 In the preferred embodiment of the first embodiment of the transmission hanger adjusting structure, the first buffer mechanism 81 includes:

[0093] The sliding sleeve seat 811 is installed on the side hanger 3 and located on the outer side of the guide seat 8 away from the driving gear 4; the plurality of connecting guide rods 812 are connected to the outer side away from the driving gear 4, and the sliding sleeve seat 811 is movably sleeved on the connecting guide rods 812; and the second reset member 813 is connected between the sliding sleeve seat 811 and the end cap 8121 of the connecting guide rod 812 away from the guide seat 8.

[0094] When the driving gear 4 drives the pair of driven racks 21 (driven members 2) to move close to (fold) or away from (open) synchronously, the sliding sleeve seat 811 is driven to move away from or close to the end cap 8121 of the connecting guide rod 812, so as to compress or stretch the second reset member 813, thereby providing buffer to enhance the stability of the transmission hanger adjusting structure when clamping and hanging the target workpiece 20.

[0095] The second reset member 813 is preferably a second reset spring, and can also be a hollow reset spring column.

One end of the first reset guide rod 912 extends horizontally towards the driving gear 4. A limiting block (limiting member 92) is provided at the end of the first reset guide rod 912 close to the driving gear 4. A plurality of electromagnets are provided on the magnet mounting seat. When the electromagnets are turned on and off, they attract or repel the other end of the first reset guide rod 912 relative to the limiting block (limiting member 92), thereby pushing the first reset guide rod 912 to retract away from the driving gear 4, so that the limiting block (limiting member 92) is synchronously (equidistantly) extended to allow the pair of driven rods (driven members 2) to pass. Or, after the pair of driven rods (driven members 2) are synchronously (equidistantly) extended to the position, the first reset guide rod 912 is pushed to extend towards the driving gear 4 to reset, so that the position of the limiting block (limiting member 92) is reset to abut against the corresponding driven rack 21, thereby limiting the stroke of the pair of driven rods (driven members 2) to the required extension length, completing the adjustment.

[0131] Please refer to Figures 16-17 When the upper hanging clamp 31 and the lower hanging clamp 62 clamp the upper and lower ends of the target workpiece 20 (hard or soft substrate) with a larger area, respectively, the conductive connecting member 5 may block the target workpiece 20. If the conductive connecting member 5 is folded and covers too large an area of the side surface of the target workpiece 20, the uniformity of electroplating of the target workpiece 20 will be affected. Therefore, the width dimension of the target workpiece 20 needs to be considered, and an effective range of the thickness (width dimension) of the conductive connecting member 5 is set, which can not only avoid the thickness (width dimension) of the conductive connecting member 5 exceeding the effective range to cause the target workpiece 20 to have an electroplating ineffective area on the side surface, but also ensure that the conductive connecting member 5 has sufficient structural strength.
