A loading and unloading clamping mechanism

Abstract

The present invention belongs to the technical field of electroplating equipment, and specifically relates to a loading and unloading opening and clamping mechanism. When loading or unloading, the clamp at the upper end of the clamping and fixing mechanism is clamped and positioned by the first clamping mechanism, and the material clamp at the lower end of the clamping and fixing mechanism is clamped and positioned by the second clamping mechanism to prevent the clamp or the material clamp from being bent when opening the clamp. According to the size of the thin plate, the side edges of the clamping and fixing mechanism are clamped by the first adjustment mechanism and the side edges of the clamping and fixing mechanism are pushed or pulled to adjust the size of the clamping cavity in the width direction. When the first clamping mechanism and the second clamping mechanism are clamped, the lower edge is pushed and pulled by the second adjustment mechanism to adjust the size of the clamping cavity in the length direction, thereby realizing automatic adjustment of the clamping frame structure. After the clamping and fixing mechanism is adjusted, the clamp is opened by the first opening and clamping mechanism, and the material clamp is opened by the second opening and clamping mechanism, thereby facilitating the automation of loading or unloading of the thin plate.

Description

Technical Field

[0001] The invention belongs to the technical field of electroplating equipment, and in particular relates to a loading and unloading clamping mechanism. Background Art

[0002] In the electroplating industry, when a circuit board is electroplated through an electroplating tank to electroplate a metal layer of corresponding thickness, it is necessary to use a clamp to clamp it on the second side of the hanger, and the first side of the clamp is connected to a plurality of clamps arranged at intervals along the width direction of the circuit board through a clamp fixing plate, and the first end of the plate is clamped and fixed by the clamp, and the circuit board is suspended in the corresponding electroplating tank, and the loading and unloading and clamping mechanism is driven to move by the conveying mechanism to drive the circuit board to be electroplated in electroplating tanks with different functions. During electroplating, the cathode current is guided from the conductive plate to the clamp fixing plate, and then the current is guided from the clamp fixing plate to the clamp. After the clamp is charged, it provides cathode electricity to the circuit board, so that the charged circuit board reacts with the metal cations in the electroplating tank to complete the electroplating.

[0003] In order to ensure the stability of clamping and the verticality of the circuit board in the electroplating tank, and to ensure the quality of electroplating, usually the middle and both ends of the upper edge of the circuit board need to be fixed with clamps, and the clamps are electrically connected to the clamp fixing plate. However, during electroplating, it is often necessary to plate circuit boards of different thicknesses. For thicker circuit boards, due to the higher strength of the circuit board itself, the upper edge of the circuit board is clamped by the first clamp of the clamp located on the first side of the circuit board, and the circuit board can maintain a good verticality by using the clamp and the circuit board's own gravity. However, for thinner circuit boards, especially thin plates with a thickness of less than 0.3mm, their own strength is not enough to ensure the verticality of the board surface. If the upper edge of the thin plate is clamped only by the clamp on the first side of the thin plate, the second end of the thin plate is prone to shaking, warping, tearing, overlapping, etc., resulting in uneven coating and affecting the electroplating quality of the circuit board.

[0004] In the prior art, for example, Chinese patent document CN205313696U discloses a loading and unloading clamping device, which uses an upper clamping mechanism to clamp and fix the upper end of the clamp, and a lower clamping mechanism to clamp and fix the material clamp at the lower end, so as to prevent the clamp or material clamp from being bent when opening the clamp. The upper and lower clamping mechanisms are used to apply pressure to the clamp or material clamp to open the clamp or material clamp, thereby realizing automatic loading or unloading of thin plates. However, the clamping device of the above structure cannot meet the requirements of loading and unloading of the clamping and fixing mechanism of the newly developed adjustable ground frame structure surrounded by the clamp, the material clamp and the first connecting member. The clamping device of the above structure can only be used for the loading and unloading of the clamping and fixing mechanism without a frame and the clamping and fixing mechanism of the non-adjustable ground frame structure, that is, it can only be used for the loading and unloading of thin plates of fixed size, but the online automatic adjustment of the clamping and fixing mechanism of the adjustable ground frame structure cannot be realized.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. 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.

[0070] Example 1

[0071] The loading and unloading and clamping mechanism of this embodiment is suitable for the loading and unloading and clamping of the clamping and fixing mechanism 8 with a square frame structure having a clamping cavity surrounded by the clamp 9, the first connecting member 12 and the material clamp 10, such as Figures 1 to 9 As shown, it includes a mounting frame 5, a first clamping mechanism 1, a first opening clamping mechanism 3, a second clamping mechanism 2, a second opening clamping mechanism 4, a first adjustment mechanism 6 and a second adjustment mechanism 7. The first clamping mechanism 1, the first opening clamping mechanism 3 and the first adjustment mechanism 6 are arranged at the upper end of the mounting frame 5, and the first adjustment mechanism 6 is arranged at the upper ends of the first clamping mechanism 1 and the first opening clamping mechanism 3, the second clamping mechanism 2, the second opening clamping mechanism 4 and the second adjustment mechanism 7 are arranged at the lower end of the mounting frame 5, and the second adjustment mechanism 7 is arranged at the lower end of the second clamping mechanism 2 and the second opening clamping mechanism 4. The first clamping mechanism 1 can be driven to approach or move away from the clamp 9 electrically connected to the conductive plate 11 at the upper end of the clamping and fixing mechanism 8 to clamp or release the clamp 9. The second clamping mechanism 2 can be driven to approach or move away from the material clamp 10 at the lower end of the clamping and fixing mechanism 8 to clamp or release the material clamp 10. The first adjustment mechanism 6 includes a first adjustment member and a first adjustment driving member. The first adjustment driving member drives the first adjustment member to approach or move away from the clamping and fixing mechanism 8 to clamp or release the clamping and fixing mechanism 8. When clamping, the first adjustment member applies a pulling force or a pushing force to the side of the clamping and fixing mechanism 8, specifically the side of the clamp 9, to adjust the width direction of the clamping cavity. Figure 2The second adjustment mechanism 7 includes a second adjustment member 71 and a second adjustment drive member 72. The second clamping mechanism 2 and the second clamping mechanism 4 are suitable for being installed on the second adjustment member 71. When the first clamping mechanism 1 and the second clamping mechanism 2 are both clamped, the second adjustment drive member 72 drives the lower edge of the clamping and fixing mechanism 8, i.e., the material clamp 10, to move closer to or away from the upper edge, i.e., the clamp 9, so as to adjust the length direction of the clamping cavity, i.e., Figure 2 The first clamping mechanism 3 is suitable for applying pressure to the clamp 9 when the first clamping mechanism 1 is clamped so that the clamp 9 opens to form a gap for clamping the upper edge of the thin plate. The second clamping mechanism 4 is suitable for applying pressure to the material clamp 10 when the second clamping mechanism 2 is clamped so that the material clamp 10 opens to form a gap for clamping the lower edge of the thin plate.

[0072] For the first adjustment mechanism 6, if Figure 4 and Figure 5 As shown, it includes a first adjustment member, a first adjustment driving member and a first guide mechanism 66. The first adjustment member includes a clamping block mechanism 63 and a clamping block mechanism driving member 64. The clamping block mechanism 63 and the clamping block mechanism driving member 64 each include two groups, which are respectively arranged on both sides of the clamping and fixing mechanism 8. Figure 5 On the left and right sides shown, each group of clamping block mechanisms 63 includes two clamping blocks that are relatively set opposite to each other and are in the shape of right-angled trapezoids. A V-shaped clamping groove 631 is formed between the two clamping blocks. The two clamping blocks can be driven to move closer or farther away to achieve clamping or loosening. Optionally, the clamping block mechanism 63 is an existing relatively conventional pneumatic clamping jaw mechanism or electric clamping jaw mechanism. The working principle of the specific structure is not described and limited in detail. The clamping block mechanism driving member 64 is a cylinder, which can drive the clamping block mechanism 63 away from or close to the side of the clamping and fixing mechanism 8 and drive the clamping block mechanism 63 to pull the clamping and fixing mechanism 8 outward or push the clamping and fixing mechanism 8 inward to adjust the width direction of the clamping and fixing mechanism 8 when it is close to and clamped by the clamping block mechanism 63. Figure 4 and Figure 5 As an alternative, the clamping block mechanism 63 and the clamping block mechanism driving member 64 can also be set as one, for example, set on any side of the clamping and fixing mechanism 8, that is, as shown in FIG. Figure 4 As for the first adjustment drive member, it includes an adjustment seat 61 and an adjustment seat drive member 62, and the adjustment seat 61 and the adjustment seat drive member 62 each include a, which is arranged on one side of the moving surface of the clamp 9 of the clamping and fixing mechanism 8, that is, Figure 4 The front side is shown. Figure 4 and Figure 8 As shown, a square avoidance groove 65 is provided on the adjustment seat 61 corresponding to the position of the clamp 9 at the upper edge of the clamping fixing mechanism 8, and the clamping block mechanism 63 and the clamping block mechanism driving member 64 are arranged on both sides of the avoidance groove 65 in the length direction. Figure 4On the left and right sides of the avoidance groove 65 shown in the figure, the adjustment seat driving member 62 is arranged on the mounting frame 5 and the driving end is connected to the adjustment seat 61, driving the adjustment seat 61 to approach or move away, that is, backward or forward, so that the clamping block mechanism 63 and the clamping block mechanism driving member 64 are close to or away from the clamping fixing mechanism 8. The first guide mechanism 66 is arranged at the lower end of the adjustment seat 61, as shown in FIG. Figure 5 As shown, the first slide block 661 is fixed at the bottom of the adjustment seat 61 and the first guide rail 662 is fixed at the top of the mounting frame 5. The first guide rail 662 is arranged along the Figure 5 The front-to-back direction shown extends toward the clamping and fixing mechanism 8, and is used to guide the movement of the adjustment seat 61 in the direction of approaching or moving away from the clamping and fixing mechanism 8. The first guide rail 662 includes two, which are spaced and opposite to each other on the left and right sides of the adjustment seat 61. The first slider 661 includes four, and each first guide rail 662 is provided with two first sliders 661. As a replacement, the first guide rail 662 can also be set at the bottom of the adjustment seat 61, and the corresponding first slider 661 is set at the top of the mounting frame 5. At this time, the first guide rail 662 slides relative to the first slider 661, and the first slider 661 is fixed. As a modified embodiment, the first guide rail 662 can also be a screw rod, and the first slider 661 can also be a screw rod nut. As a replaceable embodiment, the avoidance groove 65 can also be not set on the adjustment seat 61, and it is only necessary that the clamping block mechanism driving member 64 can drive the clamping block mechanism 63 to approach or move away from the side of the clamping and fixing mechanism 8 to clamp or release, and when clamping, it can pull or push the side of the clamping and fixing mechanism 8 to adjust the width direction size of the clamping and fixing mechanism 8. As an alternative embodiment, the first guide mechanism 66 may not be provided.

[0073] For the second adjustment mechanism 7, Figure 6 to Figure 7 As shown, it includes a second adjustment member 71, a second adjustment drive member 72 and a second guide mechanism 73. The second adjustment member 71, the second adjustment drive member 72 and the second guide mechanism 73 each include two groups, which are located on both sides of the moving surface of the material clamp 10, that is, as shown in FIG. Figure 6 On the left and right sides shown in the figure, the second adjustment member 71 is plate-shaped, and the second adjustment driving member 72 includes a rotating rod 721 and a driving frame 722. The rotating rod 721 can be driven to rotate on the mounting frame 5. The top end of the driving frame 722 is fixed to the bottom end of the second adjustment member 71, and the bottom end is sleeved on the rotating rod 721. The rotation of the rotating rod 721 can make the driving frame 722 move along the axis direction of the rotating rod 721, that is, Figure 6The vertical movement drives the second adjusting member 71 to move up and down. Since both the second clamping mechanism 2 and the second unclamping mechanism 4 are provided on the second adjusting member 71, they will move up and down synchronously with the second adjusting member 71. Since the second adjusting member 71 moves up and down after the second clamping mechanism 2 clamps and holds the lower edge of the clamping fixture 10 of the clamping and fixing mechanism 8, it can push the clamping fixture 10 to move up and down along the first connecting member 12 on the side of the clamping and fixing mechanism 8, thereby realizing the adjustment of the vertical dimension, that is, the length dimension, of the clamping and fixing mechanism 8. The self-rotation of the rotating rod 721 is driven by a motor. Specifically, a transmission wheel can be sleeved on the rotating rod 721, and the transmission wheel meshes with the gear on the output shaft of the motor to achieve this. The two rotating rods 721 can be synchronously rotated by the same motor drive, such as through a synchronous belt or a synchronous chain. The specific implementation is not described in detail and is not limited. Optionally, the driving frame 722 is a U-shaped driving frame. The second guiding mechanism 73 includes second guide rails 731 extending vertically on the inner side edges of the mounting frame 5 and second sliders 732 mounted on the second adjusting member 71. There are four groups of second guide rails 731 in total, eight in number, two in a group, and they are respectively arranged oppositely on the inner side of the front end and the inner side of the rear end of the mounting frame 5 as shown in Figure 6 The inner sides of the front end and the rear end are respectively provided with a group on the left and right sides. As an alternative, the second guide rails 731 can also be provided on the second adjusting member 71, and the second sliders 732 are provided on the mounting frame 5. At this time, the second guide rails 731 slide relative to the second sliders 732, and the second sliders 732 are fixed. As a deformable embodiment, the second guide rails 731 can also be lead screws, and the second sliders 732 can also be lead screw nuts. As an alternative embodiment, the second guiding mechanism 73 can also be not provided.

There are two groups of the first clamping member 102 and the first clamping driving member 101, and the two groups are respectively arranged on both sides of the moving surface of the fixture 9, that is, on the left and right sides as shown in Figure 1 . As shown in Figure 5 , the first clamping driving member 101 is a group of multiple cylinders arranged side by side, and the first clamping member 102 is a C-shaped strip-like plate structure, that is, the first clamping member 102 extends along the width direction of the mounting frame 5, that is, the left and right direction as shown in Figure 5 . The C-shaped structure is set to facilitate the installation of the first unclamping mechanism 3.

[0075] For the second clamping mechanism 2, as shown in Figure 1 , Figure 2 and Figure 7As shown, it includes a second clamping member 22 and a second clamping driving member 21. There are two sets of the second clamping member 22 and the second clamping driving member 21, and the two sets are respectively arranged on both sides of the moving surface of the material clamp 10, that is, on the left and right sides as shown in Figure 7 shown. The second clamping driving member 21 is a plurality of cylinders arranged side by side, and the second clamping member 22 is a strip-shaped plate structure, that is, the second clamping member 22 extends along the width direction of the mounting bracket 5, that is, in the front-back direction as shown in Figure 7 shown. Optionally, the length of the second clamping member 22 is equivalent to the length of the first clamping member 102.

[0076] For the first clamping release mechanism 3 and the second clamping release mechanism 4, as shown in Figure 5 and Figure 7 shown, it includes a clamping release driving member and a clamping release push rod. The clamping release driving member is a plurality of cylinders arranged side by side, and the clamping release push rod extends along the width direction of the mounting bracket 5, that is, in the front-back direction as shown in Figure 7 shown, that is, the clamping release push rod extends in the same direction as the first clamping member 102 and the second clamping member 22. For the convenience of description, the clamping release push rod of the first clamping release mechanism 3 is described as the first clamping release push rod, and the clamping release driving member of the first clamping release mechanism 3 is described as the first clamping release driving member 31; the clamping release push rod of the second clamping release mechanism 4 is described as the second clamping release push rod 42, and the clamping release driving member of the second clamping release mechanism 4 is described as the second clamping release driving member 41.

[0077] As shown in Figure 5 shown, the first clamping release push rod is arranged in the receiving groove of the U-shaped first clamping member 102 and extends out of the first clamping member 102 at both ends, that is, at the left and right ends as shown in Figure 5 shown. The first clamping release driving member 31 is located on both sides of the first clamping driving member 101. The first clamping release driving member 31 is a cylinder, and a U-shaped driving block 310 is provided at the driving end of the cylinder. A fixing hole 311 for connecting the first clamping release push rod is provided on the driving block 310, that is, the part of the first clamping release push rod extending out of the first clamping member 102 is inserted into the fixing hole 311, so that the first clamping release push rod can be jointly driven by the first clamping release driving members 31 on both sides to apply pressure to the fixture 9 when the first clamping mechanism 1 clamps. The first clamping release driving member 31 and the first clamping release push rod both include two sets, which are respectively arranged on both sides of the moving surface of the fixture 9, that is, on the left and right sides as shown in Figure 5 shown, and each set of the first clamping release push rod corresponds to each set of the first clamping member 102.

[0078] For the second clamping release mechanism 4, as shown in Figure 7 shown, the second clamping release driving member 41 is also a cylinder, including two, along the width direction of the mounting bracket 5, that is, as shown in Figure 7As shown in the figure, the second clamping push rod 42 is also in a strip shape, and the two second clamping driving members 41 jointly drive the second clamping push rod 42 to approach or move away from the material clamp 10 and apply pressure to the material clamp 10 when the second clamping mechanism 2 is clamped. Fig. 9 The material clamp 10 shown is composed of a connecting seat 1001 and a material clamping component 1002, and the material clamping component 1002 is movably arranged at the upper end position of the connecting seat 1001, and the clamping position of the second clamping mechanism 2 is the bottom of the connecting seat 1001, that is, the clamping position of the second clamping mechanism 2 is lower than the position of the material clamping component 1002, so it is necessary to set the second clamping mechanism 4 at the upper end of the second clamping mechanism 2, that is, the vertical height of the second clamping driving member 41 is higher than the vertical height of the second clamping driving member 21, so that the second clamping push rod 42 is located at the second clamping The upper end of the holding member 22, and when the second clamping member 22 clamps the lower edge of the clamping fixing mechanism 8, that is, the lower edge of the connecting seat of the material clamp 10, the second clamping push rod 42 located above pushes the material clamping member 1002 on the material clamp 10 to realize the clamping of the material clamp 10. Since the material clamping member 1002 is clamped or released by the biasing force of the biasing member toward or away from one of the end faces of the connecting seat, it only needs to apply pressure in the opposite direction of the biasing force of the biasing member to overcome the biasing force to open the clamp. Therefore, only one second clamping mechanism 4 needs to be set, for example, it can be set as Figure 7 As shown, above the second clamping mechanism 2 on the left side, the material clamp 10 is opened by squeezing the material clamp component 1002 on the material clamp 10 to the right so that the material clamp 10 forms a gap for clamping the lower edge of the thin plate.

[0079] The specific structure of the clamping and fixing mechanism 8 will not be described in detail here. For details, please refer to the structures of the clamping and fixing mechanism and the clamping and fixing mechanism of the hanger applied for on the same day.

[0080] As for the mounting frame 5, two mounting frames 5 are included. Figure 6 As shown, the two mounting frames 5 are distributed on the left and right and are connected at the bottom by a connecting plate (not shown), and a gap is formed between the two mounting frames 5 for the clamping and fixing mechanism 8 to be placed.

[0081] The loading and unloading material opening and clamping mechanism of the present invention firstly utilizes the first clamping mechanism 1 and the second clamping mechanism 2 to clamp the clamp 9 at the upper edge and the material clamp 10 at the lower edge of the clamping and fixing mechanism 8 respectively, and then utilizes the first adjusting mechanism 6 to clamp the clamp of the clamping and fixing mechanism 8 and adjusts the width direction size of the clamping cavity of the clamping and fixing mechanism 8 by pulling the clamping and fixing mechanism 8 outward from both sides or squeezing the clamping and fixing mechanism 8 inward from both sides, and then uses the second adjusting mechanism 7 to push the material clamp 10 vertically, that is, the length direction of the clamping and fixing mechanism 8 close to or away from the clamp 9 to adjust the length direction size of the clamping and fixing mechanism 8, and then uses the first opening and clamping mechanism 3 and the second opening and clamping mechanism 4 to apply pressure to the clamp 9 and the material clamp 10 respectively to open the gap for forming the upper and lower edges of the clamped thin plate, and put the thin plate into the clamping cavity of the clamping and fixing mechanism 8, and then the first opening and clamping mechanism 3 and the second opening and clamping mechanism 4 are released away from the clamping and fixing mechanism 8, and the material clamp 10 and the clamp 9 automatically clamp the lower and upper edges of the thin plate respectively. During the unloading process, the first clamping mechanism 1 and the second clamping mechanism 2 first clamp the upper edge and the lower edge of the thin plate, and then the first opening clamping mechanism 3 and the second opening clamping mechanism 4 respectively approach the clamp 9 and the material clamp 10 and apply pressure, thereby realizing the automation of unloading and loading and improving production efficiency.

[0082] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the protection scope of the invention.
