Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to an electroplated flying target copper strip, an electroplated flying target and a circuit board electroplating device. Background Art

[0002] During the processing of circuit boards, it is usually necessary to use circuit board electroplating equipment to electroplate the circuit boards. In the prior art, the circuit board electroplating equipment generally includes a crane and an electroplating target. The crane includes a crane body and a lifting device installed on the crane body. The lifting device is connected to the electroplating target so as to drive the electroplating target to rise and fall, and the crane body can drive the electroplating target to move horizontally. The electroplating target includes a copper bar, both ends of which are movably installed on the crane body and are connected to the lifting device. A clamp for clamping the circuit board is installed on the copper bar. The crane drives the copper bar to rise and fall or move horizontally, so that the circuit board is immersed in different potions for electroplating. Since the copper bar is easily corroded by the electroplating solution during long-term use, and the crane drives the copper bar to rise and fall or move horizontally frequently, it is easy to swing and vibrate during the process, and the copper bar also needs to bear the gravity of the clamp and the circuit board, which causes the copper bar to be easily severely deformed or even broken. In severe cases, the entire copper bar must be replaced, which is difficult to replace and has high cost. Utility Model Content

[0044] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0045] Reference Figures 1 to 9 An embodiment of the utility model provides an electroplated target copper bar, comprising at least one group of copper block assemblies 101, each group of copper block assemblies 101 comprising at least two copper blocks 100, wherein at least one copper block 100 can be connected to a clamp for clamping a circuit board, all copper blocks 100 are arranged in sequence along the front-to-back direction, a clamping structure is provided between two adjacent copper blocks 100, the clamping structure comprises a first clamping portion 110 and a second clamping portion 120 which can be clamped to each other, the first clamping portion 110 is provided on one of the copper blocks 100, and the second clamping portion 120 is provided on the other copper block 100.

[0046] By adopting the electroplated target copper bar of the embodiment of the utility model, the electroplated target copper bar is divided into at least one group of copper block components 101, each group of copper block components 101 includes at least two copper blocks 100 arranged in sequence along the front-to-back direction, and a clamping structure capable of being clamped to each other is provided between two adjacent copper blocks 100, that is, all copper blocks 100 in the copper block component 101 are clamped and connected in sequence along the front-to-back direction, and at least one of the copper blocks 100 can be connected to a clamp, and when in use, the two ends of the electroplated target copper bar are connected to the main body of the overhead crane, and the circuit board is clamped on the clamp, and the clamp is driven to move by the clamped copper blocks 100 so as to immerse the circuit board in different potions for electroplating. When the electroplated target copper bar of the embodiment of the utility model is deformed or broken, it is only necessary to remove the corresponding copper block 100 for replacement, without replacing the entire copper bar structure, thereby reducing the replacement and maintenance cost of the copper bar structure. In addition, in the electroplated target structure of the embodiment of the utility model, two adjacent copper blocks 100 in the copper block assembly 101 are connected by snap-fitting, so compared with the prior art of replacing the entire copper bar, the operation of replacing a single copper block 100 is simpler and more convenient.

[0047] It is understandable that at least one of the copper blocks 100 can be connected to a clamp for clamping a circuit board. Specifically, in order to facilitate the copper bar to more stably fix the circuit board and drive the circuit board to move to the medicine tank, a clamp for clamping the circuit board can be connected to each copper block 100. Figures 1 to 9 Each copper block 100 is provided with a mounting portion 114 for mounting a fixture, and the mounting portion 114 is a mounting hole opened in the copper block 100, and the fixture can be mounted to the mounting hole of the copper block 100 by fasteners such as screws and bolts. Of course, in addition to this, the mounting portion 114 can also be set as a clamping portion that can be clamped and connected with the fixture, and the utility model does not make specific limitations on this.

[0048] It can be understood that, in the copper block assembly 101, all copper blocks 100 are sequentially connected by snapping in the front-to-back direction, wherein the copper blocks 100 located at the frontmost and rearmost ends may only be provided with the first snapping portion 110 or the second snapping portion 120 that can be snapped with the adjacent copper blocks 100. When the copper block assembly 101 includes at least three copper blocks 100, the copper blocks 100 located between the frontmost and rearmost copper blocks 100 may be provided with both the first snapping portion 110 and the second snapping portion 120, so as to be snapped with the copper blocks 100 on both sides; the copper blocks 100 at the frontmost and rearmost ends may be provided with both the first snapping portion 110 and the second snapping portion 120, or may only be provided with the first snapping portion 110 or the second snapping portion 120 that can be snapped with the adjacent copper blocks 100, and the present invention does not make specific limitations on this.

[0049] Reference Figures 1 to 9 In some embodiments, in the snap-in structure, a first snap-in slot 111 is provided on one side surface of the first snap-in portion 110, and the second snap-in portion 120 has a first snap-in block 121 adapted to the first snap-in slot 111, and the first snap-in block 121 can be inserted into the corresponding first snap-in slot 111 and abut against the inner top wall 113 of the first snap-in slot 111.

[0050] By adopting the above structure, the first clamping block 121 can be clamped into the corresponding first clamping groove 111 and abut against the inner top wall 113 of the first clamping groove 111, so that the second clamping portion 120 can support the first clamping portion 110 through the first clamping block 121, that is, one of the two adjacent copper blocks 100 can support the other copper block 100 through the first clamping block 121 of the second clamping portion 120, thereby preventing the two adjacent copper blocks 100 from being dislocated or separated in the up and down directions, resulting in an unstable structure of the electroplated target copper strip. In addition, the clamping structure is set as a structure in which the first clamping block 121 and the first clamping groove 111 are clamped with each other, which is simple in structure and easy to process.

[0051] In addition, since the two ends of the electroplated target copper bar need to be connected to the overhead traveling crane body during use, each copper block 100 can be limited from both ends of the electroplated target copper bar to prevent two adjacent copper blocks 100 from being misaligned or separated in the front-to-back direction.

[0052] Reference Figures 1 to 9 In some embodiments, the first card slot 111 is specifically opened on the lower surface of the first card portion 110 , so that the first card block 121 can be inserted into the first card slot 111 from bottom to top and directly abut against the inner top wall 113 of the first card slot 111 .

[0053] It is understandable that the first card block 121 can be inserted into the corresponding first card slot 111 and abut against the inner top wall 113 of the first card slot 111. Figures 1 to 9 As an exemplary illustration, in some embodiments, in order to stably clamp two adjacent copper blocks 100, the first clamping block 121 can also be abutted against the inner bottom wall of the first clamping groove 111. At this time, the first clamping portion 110 can support the second clamping portion 120 through the inner bottom wall of the first clamping groove 111, and the utility model does not make any specific limitation on this.

[0054] It is understandable that the first clamping slot 111 can be a blind hole formed on one side of the first clamping portion 110, and the first clamping block 121 can be directly inserted into the blind hole to clamp the first clamping portion 110 and the second clamping portion 120 together. When the blind hole is directly formed on the bottom wall or the top wall of the first clamping portion 110 in the up-down direction, the structure can also limit the dislocation or separation of two adjacent copper blocks 100 in the front-to-back direction, so that the structure of the electroplated target copper strip is more stable.

[0055] Reference Figures 1 to 9 In some embodiments, the second clamping portion 120 further includes a second clamping block 122 connected to the outer side wall of the first clamping block 121, and the projection of the second clamping block 122 of the first clamping block 121 in the vertical direction is T-shaped. The first clamping portion 110 is provided with a second clamping slot 112 adapted to the second clamping block 122, and the first clamping slot 111 and the second clamping slot 112 are both provided on the bottom wall of the first clamping portion 110, the first clamping slot 111 penetrates the outer side wall of the first clamping portion 110, and the second clamping slot 112 is located on the inner side of the first clamping slot 111 and communicates with the first clamping slot 111.

[0056] In the above structure, the second clamping portion 120 further has a second clamping block 122 connected to the outer side wall of the first clamping block 121, wherein the outer side wall of the first clamping block 121 specifically refers to a side wall of the first clamping block 121 facing the first clamping portion 110 in the same set of clamping structures. The first clamping groove 111 penetrates the outer side wall of the first clamping portion 110, wherein the outer side wall of the first clamping portion 110 specifically refers to a side wall of the first clamping portion 110 facing the second clamping portion 120 in the same set of copper block components 101.

[0057] By adopting the above structure, a second clamping block 122 is connected to the outer side wall of the first clamping block 121, so that the projections of the first clamping block 121 and the second clamping block 122 in the up and down directions are T-shaped, and a second clamping groove 112 adapted to the second clamping block 122 is provided in the first clamping portion 110. Therefore, when the first clamping block 121 and the second clamping block 122 are clamped into the corresponding first clamping groove 111 and the second clamping groove 112 from bottom to top, if the two adjacent copper blocks 100 tend to move relative to each other in the front-to-back direction or the left-to-right direction, the side wall of the second clamping block 122 can abut against the inner wall of the second clamping groove 112. This structure can further limit the two adjacent copper blocks 100, avoid relative movement, dislocation or separation between the two adjacent copper blocks 100, make the clamping between the two more firm, and thus make the structure of the electroplated target copper strip more stable.

[0058] It is understandable that in the above structure, by penetrating the first card slot 111 through the outer wall of the first clamping portion 110 , the first clamping block 121 and the second clamping block 122 can be easily inserted into the corresponding first card slot 111 and the second card slot 112 from bottom to top.

[0059] Reference Figures 1 to 9 In some embodiments, the second clamping block 122 protrudes upward relative to the first clamping block 121, and the second clamping slot 112 is a through slot provided in the first clamping portion 110, so that when the second clamping block 122 is inserted into the second clamping slot 112, the side wall of the upwardly protruding portion of the second clamping block 122 can also abut against the inner wall of the second clamping slot 112, thereby further improving the stability of the clamping between two adjacent copper blocks 100. In addition, setting the second clamping slot 112 as a through slot provided in the first clamping portion 110 can also facilitate the processing of the first clamping portion 110.

[0060] Reference Figures 1 to 9 In some embodiments, in the copper block assembly 101, each copper block 100 is provided with a first clamping portion 110 and a second clamping portion 120. Among two adjacent copper blocks 100, the first clamping portion 110 of one copper block 100 can be clamped with the second clamping portion 120 of the other copper block 100.

[0061] By adopting the above structure, each copper block 100 is provided with a first clamping portion 110 and a second clamping portion 120, which not only enables two adjacent copper blocks 100 to be clamped and connected to each other through the first clamping portion 110 and the second clamping portion 120, but also, all copper blocks 100 are arranged to have the same or similar structure, which can facilitate the production and processing of the copper blocks 100.

[0062] Reference Figures 1 to 9In some embodiments, there are two groups of copper block assemblies 101, and the two groups of copper block assemblies 101 are arranged at intervals in the front-to-back direction. A group of locking assemblies 200 is provided between two adjacent groups of copper block assemblies 101, and the locking assemblies 200 can connect and lock the copper blocks 100 located on both sides of the locking assemblies 200.

[0063] By adopting the above-mentioned components, the number of copper block assemblies 101 is set to two groups, and the locking component 200 can connect and lock the copper blocks 100 located on both sides of the locking component 200, that is, the locking component 200 can connect and lock the copper block 100 located at the rear end of the previous group of copper block assemblies 101 and the copper block 100 located at the front end of the latter group of copper block assemblies 101, and then the two groups of copper block assemblies 101 can be connected and locked by the locking component 200, thereby further improving the structural stability of the electroplated target copper bar.

[0064] It can be understood that the number of the above copper block assemblies 101 is two groups, which is only for Figures 1 to 9 As an exemplary illustration, in some embodiments, the number of copper block assemblies 101 can also be set to three groups, four groups, five groups or more groups, which is not specifically limited by the present invention. It should be noted that when the number of copper block assemblies 101 is three groups or more, all copper block assemblies 101 are arranged at intervals along the front-to-back direction, and a group of locking assemblies 200 is provided between each two adjacent copper block assemblies 101. The locking assemblies 200 can connect and lock the copper blocks 100 located on both sides of the locking assemblies 200, so that the two adjacent groups of copper block assemblies 101 can be connected and locked by the locking assemblies 200.

[0065] Reference Figures 1 to 9 In some embodiments, the number of copper block assemblies 101 is two groups. In each group of copper block assemblies 101, the second clamping portions 120 of all copper blocks 100 are arranged toward the locking assembly 200, and the second clamping portions 120 of the copper blocks 100 located at one end of the copper block assembly 101 close to the locking assembly 200 are fixedly connected to the locking assembly 200.

[0066] By adopting the above structure, the second clamping parts 120 of all copper blocks 100 are arranged toward the locking assembly 200, so that the locking assembly 200 can connect and lock the second clamping parts 120 of the copper blocks 100 on both sides thereof. Since the two groups of copper block assemblies 101 are fixedly connected to the locking assembly 200 through the second clamping parts 120, that is, the locking assembly 200 is fixedly connected to two identical structures, only two groups of structures for fixedly connecting to the second clamping parts 120 need to be provided on the locking assembly 200, so that the two groups of copper block assemblies 101 can be connected and locked, thereby making the production and processing of the locking assembly 200 more convenient.

[0067] It can be understood that, in addition to arranging the second clamping portions 120 of all copper blocks 100 toward the locking assembly 200 in each group of copper block assemblies 101, in some embodiments, the first clamping portions 110 of all copper blocks 100 in each group of copper block assemblies 101 can also be arranged toward the locking assembly 200, so that the two groups of copper block assemblies 101 are fixedly connected to the locking assembly 200 via the first clamping portions 110.

[0068] It is understandable that the above structure is only an exemplary description of the present invention. In some embodiments, in one group of copper block assemblies 101, the first clamping parts 110 of all copper blocks 100 are arranged toward the locking assembly 200, and the copper blocks 100 located at one end of the copper block assemblies 101 close to the locking assembly 200 are fixedly connected to the locking assembly 200 through the first clamping parts 110. In another group of copper block assemblies 101, the second clamping parts 120 of all copper blocks 100 are arranged toward the locking assembly 200, and the copper blocks 100 located at one end of the copper block assemblies 101 close to the locking assembly 200 are fixedly connected to the locking assembly 200 through the second clamping parts 120. In this case, the locking assembly 200 needs to be provided with a structure for fixedly connecting with the first clamping part 110 and a structure for fixedly connecting with the second clamping part 120.

[0069] Reference Figures 1 to 9 In some embodiments, the locking assembly 200 includes two locking members 210 that can cooperate to lock or unlock. The locking member 210 has a connecting portion 220 and two clamping portions 230 corresponding to the two groups of copper block assemblies 101. The two clamping portions 230 are correspondingly arranged on the front and rear sides of the connecting portion 220. When the two locking members 210 are arranged relative to each other in the left and right directions, the two connecting portions 220 can be connected to each other, and the two opposite clamping portions 230 can cooperate to clamp the corresponding second clamping portion 120.

[0070] By adopting the above structure, during installation, the two locking members 210 are arranged relatively along the left-right direction and placed between the two groups of copper block assemblies 101, the two clamping parts 230 of the locking members 210 are aligned with the second clamping parts 120 at the ends of the two groups of copper block assemblies 101, the two locking members 210 are relatively moved close to each other, and the connecting parts 220 of the two locking members 210 are connected together, thereby, the two clamping parts 230 located on the front side can clamp and fix the second clamping part 120 of the rearmost copper block 100 of the previous group of copper block assemblies 101, and the two clamping parts 230 located on the rear side can clamp and fix the second clamping part 120 of the frontmost copper block 100 of the next group of copper block assemblies 101, so that the front and rear groups of copper block assemblies 101 can be connected and locked, further improving the structural stability of the electroplated target copper bar, with a simple structure and convenient operation.

[0071] It is understandable that, referring to Figures 1 to 9 The connection part 220 is provided with a connection hole 221, and the connection holes 221 on the connection parts 220 of the two locking members 210 correspond to each other. When connecting, screws, bolts or other fasteners are sequentially passed through the corresponding connection holes 221 on the two connection parts 220 to connect and lock the two locking members 210 together. In addition to providing the connection hole 221 on the connection part 220, a clamping member can also be provided on the connection part 220 so that the connection parts 220 of the two locking members 210 are clamped and connected to each other, and the present invention does not make any specific limitation on this.

[0072] It can be understood that, in some embodiments, the second clamping portion 120 is provided with a clamping block that can be engaged with the first clamping portion 110, and the clamping portion 230 of the locking member 210 is provided with a clamping groove corresponding to the clamping block. When the two locking members 210 are arranged relative to each other in the left and right directions, the two clamping grooves located on the front side can clamp and fix the clamping block of the rearmost copper block 100 of the first group of copper block assemblies 101, and the two clamping grooves located on the rear side can clamp and fix the clamping block of the frontmost copper block 100 of the second group of copper block assemblies 101, thereby facilitating the clamping and fixing of the front and rear groups of copper block assemblies 101, so that the structure of the electroplated target copper bar is more stable.

[0073] Specifically, refer to Figures 1 to 9 In some embodiments, the second clamping portion 120 has a first clamping block 121 and a second clamping block 122 that are connected to each other, and the projections of the first clamping block 121 and the second clamping block 122 in the up and down directions are T-shaped. The first clamping portion 110 is provided with a first clamping groove 111 and a second clamping groove 112 that correspond one-to-one to the first clamping block 121 and the second clamping block 122. The clamping portion 230 of the locking member 210 is provided with a first clamping groove 231 and a second clamping groove 232 that correspond one-to-one to the first clamping block 121 and the second clamping block 122. When the two locking members 210 are arranged relative to each other in the left and right directions, the two opposite first clamping grooves 231 can cooperate to clamp the corresponding first clamping block 121, and the two opposite second clamping grooves 232 can cooperate to clamp the second clamping block 122.

[0074] Reference Figures 10 to 12 In some embodiments, the upper surfaces of all copper blocks 100 in the two groups of copper block assemblies 101 are flush, and in the copper block assembly 101 located on the front side of the locking assembly 200, the thickness of all copper blocks 100 gradually decreases in sequence from the front to the back; in the copper block assembly 101 located on the rear side of the locking assembly 200, the thickness of all copper blocks 100 gradually increases in sequence from the front to the back.

[0075] Since the electroplated target copper bar is prone to sway and vibrate due to movement and lifting during use, and the copper bar also needs to bear the gravity of the fixture and the circuit board, it is easy to cause the two ends of the copper bar to be subjected to greater force, and it is more likely to be fatigued, deformed or even broken. Therefore, by adopting the electroplated target copper bar structure of the embodiment of the utility model, the upper surfaces of all copper blocks 100 are arranged flush, the thickness of all copper blocks 100 of the front copper block assembly 101 gradually decreases from front to back, and the thickness of all copper blocks 100 of the rear copper block assembly 101 gradually increases from front to back, that is, the two groups of copper blocks The thickness of all the copper blocks 100 of the assembly 101 gradually decreases in the direction approaching the locking assembly 200, so that the lower surface heights of all the copper blocks 100 of the two groups of copper block assemblies 101 gradually increase in the direction approaching the locking assembly 200, thereby making the lower surface of the electroplated target copper bar arched. In this structure, the copper blocks 100 towards the middle are smaller in volume and lighter in weight, thereby further reducing the stress on the copper blocks 100 at both ends, thereby alleviating metal fatigue, reducing the risk of deformation or even breakage of the electroplated target copper bar, and increasing the service life of the electroplated target copper bar.

[0076] It is understandable that, referring to Figures 9 to 12 In some embodiments, each copper block 100 is provided with a first clamping portion 110 and a second clamping portion 120, a first clamping slot 111 is provided on the lower surface of the first clamping portion 110, and the second clamping portion 120 has a first clamping block 121 adapted to the first clamping slot 111. In two adjacent copper blocks 100, the first clamping block 121 of one copper block 100 can be clamped into the first clamping slot 111 of the other copper block 100 and abut against the inner top wall 113 of the first clamping slot 111. The upper surfaces of all copper blocks 100 are flush, and in the first group of copper block assemblies 101, the thickness of the first clamping block 121 decreases gradually from front to back, and in the second group of copper block assemblies 101, the thickness of the first clamping block 121 increases gradually from front to back, thereby making the lower surface of the electroplated target copper strip arched. When two adjacent copper blocks 100 are connected to each other, the first clamping block 121 is clamped into the first clamping groove 111 and abuts against the inner top wall 113 of the first clamping groove 111, so that the force of each copper block 100 is concentrated on the position of the first clamping block 121, and the first clamping blocks 121 located at both ends of the copper bar are subjected to greater force. For this reason, the thickness of the first clamping block 121 is gradually reduced in the direction close to the locking component 200, so that the first clamping blocks 121 located at the front and rear sections of the copper bar are thicker and stronger, and the copper block 100 becomes lighter towards the middle, thereby further reducing the force of the first clamping blocks 121 at both ends of the copper bar, thereby alleviating metal fatigue, reducing the risk of deformation or even breakage of the electroplated target copper bar, and increasing the service life of the electroplated target copper bar.

[0077] Reference Fig.13An embodiment of the utility model further provides an electroplated target, which includes a target crossbeam 300 and an electroplated target copper bar of any of the above embodiments. The target crossbeam 300 has a first insulating seat and a second insulating seat arranged at intervals along the front-to-back direction. In the electroplated target copper bar, the copper block 100 at the front end is fixedly installed on the first insulating seat, and the copper block 100 at the rear end is fixedly installed on the second insulating seat. The copper block 100 at the front end and the copper block 100 at the rear end both have a power connection portion 115 that can be electrically connected to an external transformer.

[0078] In the above structure, by setting the target crossbeam 300, it is convenient to install and fix the electroplated target copper bar, so that the movement and lifting of the electroplated target copper bar is more convenient. By adopting the electroplated target copper bar of any of the above embodiments, the electroplated target copper bar is composed of at least one group of copper block components 101, and the copper block component 101 includes at least two copper blocks 100 that are sequentially connected and connected in the front-to-back direction. When the electroplated target copper bar is deformed or broken during use, it is only necessary to remove the corresponding copper block 100 for replacement, without replacing the entire copper bar structure, thereby reducing the replacement and maintenance cost of the copper bar structure, and compared with the existing technology of replacing the entire copper bar, the operation of replacing a single copper block 100 is simpler and more convenient, thereby reducing the maintenance cost of the electroplated target and making the maintenance of the electroplated target simpler and more convenient, shortening the maintenance time of the electroplated target.

[0079] An embodiment of the present invention further provides a circuit board electroplating device, wherein the circuit board electroplating device is provided with the electroplating target of any of the above embodiments.

[0080] By adopting the above-mentioned electroplated flying target structure, when the copper bar of the electroplated flying target is deformed or broken during use, it is only necessary to remove the corresponding copper block 100 for replacement, without replacing the entire copper bar structure, thereby reducing the replacement and maintenance cost of the copper bar structure. Compared with the existing technology of replacing the entire copper bar, the operation of replacing a single copper block 100 is simpler and more convenient, thereby making the maintenance of the electroplated flying target simpler and more convenient, shortening the maintenance time of the electroplated flying target, and further helping to improve the electroplating efficiency of the circuit board electroplating equipment.

[0081] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
