Description

Technical Field

[0001] The present invention relates to the technical field of clamp opening equipment, and in particular to a guided clamp opening device and a system having the guided clamp opening device. Background Art

[0002] In factory production, it is very common to use several parallel and continuously arranged fixtures to clamp workpieces to run on the production line.

[0003] Immersion plating refers to the process of producing a solid metal deposition layer on the metal surface by a substitution reaction of one metal replacing another metal from the solution. The conventional PCB plate electroplating process is to clamp the PCB plate with a fixture and immerse it in the solution in the tank to plate the metal layer on the PCB surface conductor; the conventional chemical plating process is also to clamp the plate with a fixture and immerse it in the solution to plate the metal layer on the plate surface through a substitution reaction.

[0004] In the existing electroplating line, the conveyor belt extends horizontally from the initial end of the electroplating to the end where the electroplating is completed. A number of clamps are fixed on the bottom edge of the conveyor belt at intervals. The substrate to be electroplated is fixed on the conveyor belt by the clamps and moves with the conveyor belt. After the electroplating is completed, the substrate needs to be removed from the clamps. The traditional working method is to manually open the clamps one by one. However, due to the continuous operation of the conveyor belt and the large number of clamps, the stability of manual clamping is poor, which affects production efficiency.

[0005] A clamping device is proposed in the prior art, which uses an arc-shaped metal ingot and fixes the arc-shaped metal ingot on the travel path of the clamp. When the clamp passes through the arc-shaped metal ingot, the clamping actuator rod on the clamp can lean against the metal ingot and move along the arc surface. The clamping actuator rod gradually opens the clamp below to complete the clamping action.

[0006] However, in order to ensure the stability of the clamping, the arc of the metal ingot surface needs to be gradually transitioned, which requires high processing precision, is difficult to process, and is costly. When there is a processing error in the clamping actuator rod or the metal ingot itself, the clamp has reached the maximum clamping position on the metal ingot. Since the metal ingot is not flexible, it will continue to move along the arc surface of the metal ingot, forcing the clamping actuator rod to continue the clamping action, which will cause damage to the clamp. Summary of the invention

[0007] Therefore, the technical problem to be solved by the present invention is that the existing guiding and clamping device has high processing cost and is easy to damage the clamp.

[0008] To this end, the present invention provides a guiding and opening device, comprising

[0009] frame;

[0010] a conveyor belt rotatably mounted on the frame;

[0011] A clamp, arranged on the conveyor belt, comprising a clamping portion for maintaining a closed clamping state, and an execution portion for driving the clamping portion to open and close;

[0012] It is characterized by further comprising:

[0013] The guide plate is fixedly mounted on the frame; it has an execution surface, which is suitable for sliding contact with the execution part that moves during the rotation of the conveyor belt, and drives the execution part to overcome the biasing force exerted on the clamping part, so that the clamping part opens; the guide plate has toughness at the contact position of the execution part corresponding to the maximum opening position of the clamping part.

[0014] The extension direction of the execution surface and the moving direction of the execution part are arranged at an angle.

[0015] The execution surface is arranged gradually away from the conveyor belt along the moving direction of the execution part.

[0016] The guide plate is a tough plate.

[0017] Both side surfaces of the guide plate are flat.

[0018] The guide plate is a stainless steel plate.

[0019] The thickness of the guide plate is 1-2 mm.

[0020] It also includes a limit block, which is fixed relative to the frame and located at a tough portion of the execution surface facing away from the execution part; a deformation space is reserved between the limit block and at least the execution surface.

[0021] A wall surface of one side of the limiting block facing the guide plate is a plane.

[0022] Also includes a base, which is detachably fixed to the frame;

[0023] The guide plate is fixedly mounted on the base, and the execution surface is arranged toward the execution part;

[0024] The limit block is fixedly mounted on the base and is located on a side of the execution surface facing away from the execution part.

[0025] The present invention provides a system with a guiding and opening device, comprising:

[0026] The guiding and clamping device described above.

[0027] Preferably, the system having the guided clamping device is an immersion plating system.

[0028] Preferably, the immersion plating system is a chemical plating line or an electroplating line.

[0029] The technical solution of the present invention has the following advantages:

[0030] 1. The present invention provides a guiding and clamping device, including a guide plate fixedly mounted on a frame, wherein the guide plate has an execution surface, and the execution surface is suitable for slidingly contacting with the execution part of the clamp moving in the process of rotating with the conveyor belt, and driving the execution part to overcome the biasing force exerted on the clamping part, so that the clamping part is opened, and the guide plate at the contact position of the execution part corresponding to the maximum opening position of the clamping part has toughness. When the clamp passes through the guide plate in the process of moving with the conveyor belt, the clamping action is automatically performed. When the clamping action reaches the maximum opening position, the guide plate in contact with the execution part has toughness, which can prevent the execution part of the clamp from continuing to open the clamp and causing damage, and effectively buffer the force received by the execution part. The service life of the clamp is improved.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] Example 1

[0045] This embodiment provides a guiding and opening device, such as Figure 1 As shown, synchronous wheels are respectively arranged on the frames 1 on both sides, and each of the synchronous wheels can be arranged on the corresponding frame 1 so as to rotate horizontally in situ. One of the synchronous wheels is connected to the driving motor, and the conveyor belt 2 is tightly wound around the two synchronous wheels. Under the drive of the driving motor, the conveyor belt 2 is suitable for rotating around the synchronous wheels.

[0046] The clamps 3 are evenly distributed on the outer peripheral surface of the lower edge of the conveyor belt 2, such as Figure 2As shown (only part of the clamp is shown), the fixed part 33 of the clamp 3 is vertically fixed on the conveyor belt 2, the top of the clamping part 31 is hinged on the fixed part 33 through the first hinge component, one end of the hinge plate 34 is hinged on the fixed part 33 through the second hinge component, one end of the execution part 32 serves as the execution end, and the other end serves as the hinge end, the hinge end is hinged on the other end of the hinge plate 34 through the third hinge component, and the hinge end of the execution part 32 is hinged on the top of the clamping part 31 through the fourth hinge component. The reset device is arranged between the execution end of the execution part 32 and the fixed part 33. In this embodiment, the reset device is two magnets 7, and the two magnets 7 are fixed on the execution part 32 and the fixed part 33 with opposite poles. The reset device can also be a tension spring, depending on specific needs.

[0047] The actuator 32, the clamping portion 31 and the hinged plate 34 form a double rocker mechanism through the above four hinged components. When the actuator 32 is operated along a first direction, the clamping portion 31 opens. When the actuator 32 is not operated or is operated in a second direction opposite to the first direction, the magnets 7 attract each other and drive the clamping portion 31 to close.

[0048] A base 6 is arranged on one side of the frame 1 facing the conveyor belt, and the base 6 is fixed to the frame 1 by bolts and other fasteners. The guide plate 4 is fixedly mounted on the base 6 and has an execution surface 41. The execution surface 41 is suitable for sliding contact with the execution part 32 moving during the rotation of the conveyor belt 2, and drives the execution part 32 to overcome the biasing force of the clamping part 31, so that the clamping part 31 is opened; the guide plate 4 at the contact position of the execution part 32 corresponding to the maximum opening position of the clamping part 31 has toughness. In this embodiment, as Figure 4 As shown, the guide plate 4 is made of a stainless steel plate with a thickness of 1 to 2 mm, and other tough plates can also be used. Both sides of the stainless steel plate are flat, which is easy to process. The extension direction of the execution surface 41 of the stainless steel plate toward the execution part 32 is set at an angle with the movement direction of the execution part 32 along the conveyor belt 2, such as Figure 3As shown, in this embodiment, the execution surface 41 is gradually arranged away from the conveyor belt 2 along the moving direction of the execution part 32 of the clamp 3, and at the initial contact end of the execution part 32 and the execution surface 41, the guide plate 4 is located between the fixed part 33 of the clamp 3 and the execution part 32. A rotatable rotating guide wheel 321 is installed at the execution end of the execution part 32. During the movement of the clamp 3, the rotating guide wheel 321 is guided by the guide plate 4 and rolls along the execution surface 41, so that the execution part 32 gradually opens, driving the clamping part 31 below to gradually open, and realizing the opening action. When the clamping part 31 is opened to the maximum position, the execution part 32 reaches the limit position and cannot continue to open. The execution part 32 overcomes the force of the guide plate 4 and presses the guide plate 4 in the opposite direction. The guide plate 4 is deformed so that the force will not act completely on the execution part 32, thereby avoiding damage to the execution part 32. When the conveyor belt 2 continues to move, the deformed guide plate 4 avoids the moving path of the execution part 32, so that the execution part 32 passes smoothly.

[0049] In order to prevent the guide plate 4 from undergoing irreversible deformation and affecting the service life of the guide plate 4, a limit block 5 is installed on the side of the guide plate 4 that has toughness at the execution surface 41 and is facing away from the execution part 32. The limit block 5 is fixed on the base 6. A deformation space is reserved between the limit block 5 and the guide plate 4. When the deformation of the guide plate 4 is large, it abuts against the limit block 5. The limit block 5 prevents the guide plate 4 from continuing to deform, thereby protecting the guide plate 4.

[0050] Of course, when the clamp 3 is a conventional clamp, that is, the clamping part 31 is in a closed state when the execution part 32 is open, and the clamping part 31 is in an open state when the execution part 32 overcomes the reset device and is closed, at this time, the execution surface 41 is gradually close to the conveyor belt 2 along the moving direction of the execution part 32 of the clamp 3, and at the initial contact end of the execution part 32 and the execution surface 41, the guide plate 4 is located on the same side of the fixing part 33 of the clamp 3 and the execution part 32, and is located outside the execution part 32. During the movement of the clamp 3, the execution part 32 is gradually closed under the guidance of the guide plate 4, so that the lower clamping part 31 is gradually opened. The limit block 5 is also installed on the side of the execution surface 41 of the guide plate 4 with toughness, facing away from the execution part 32.

[0051] As a first replaceable implementation of Example 1, the guide plate 4 can also be a spliced ​​plate, which is composed of plates with different toughness. That is, only the guide plate 4 at the contact part of the execution part 32 corresponding to the maximum opening position of the clamping part 31 is a tough plate, and the remaining parts can be conventional steel plates or other hard plates.

[0052] As a second alternative implementation of Example 1, the limit block 5 may not be provided, and the force provided by the actuator 32 can be used to cause the guide plate 4 to deform within a safe range.

[0053] Example 2

[0054] This embodiment provides a system with a guiding and clamping device, including the guiding and clamping device in Embodiment 1. Further, the system with the guiding and clamping device may be an immersion plating system, and further, the immersion plating system is a chemical plating line or an electroplating line.

[0055] Obviously, the above embodiments are merely examples for the purpose of 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 scope of protection of the invention.
