Description

Technical Field

[0001] The present invention relates to the technical field of transport equipment, and in particular to a transport structure and a workpiece processing system. Background Art

[0002] In electroplating production, the workpiece is clamped or suspended on a hanger, which is driven by a driving device to run continuously and uninterruptedly through several electroplating tanks. The electroplating line usually has a certain length, and the overall distribution of conventional electroplating tanks is linear, arc-shaped, or a combination of linear and arc-shaped.

[0003] Existing transport devices, such as electroplating production lines, generally use hanging chain conveyors. The distribution direction of the hanging chains is set above the electroplating tanks along the distribution direction of the electroplating tanks. The tooling fixtures are directly fixed on the hanging chains and move with the hanging chains.

[0004] In the above fixing method, since the tooling fixture is directly connected to the suspension chain, the suspension chain not only needs to provide the driving force for the tooling fixture to move, but also needs to bear the overall gravity of the entire tooling fixture and the workpiece to be processed in the tooling fixture, which affects the service life of the suspension chain. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the short service life of the suspension transport structure in the prior art.

[0006] To this end, the present invention provides a driving device, comprising:

[0007] A frame, a suspension conveyor arranged on the frame, and a supporting guide structure arranged in parallel along a suspension chain of the suspension conveyor;

[0008] At least one connecting member is movably supported on the supporting guide structure and connected to the suspension chain, and is driven by the suspension chain to move along the supporting guide structure; the connecting member is connected to the workpiece to be processed and bears its weight.

[0009] The supporting guide structure and the suspension chain are arranged to extend in the same direction.

[0010] The supporting guide structure and the suspension chain are arranged at intervals in the horizontal direction.

[0011] Also includes:

[0012] A matching piece is fixed on the connecting piece; the matching piece is rollingly matched with the supporting guide structure.

[0013] The supporting guide structure is a guide rail with a square cross section;

[0014] The matching piece comprises:

[0015] At least three rollers are distributed along both sides of the guide rail.

[0016] The suspension conveyor comprises a first guide groove; the suspension chain is arranged along the first guide groove;

[0017] A plurality of mounting parts are arranged at intervals on the suspension chain; and the connecting member is fixed on the mounting parts.

[0018] The hanging conveyor also includes:

[0019] A second guide groove is connected to the first guide groove; the mounting portion includes a mounting column; the mounting column is inserted into the second guide groove;

[0020] At least one limiting wheel is coaxially sleeved on the mounting column; the limiting wheel is in rolling cooperation with the two opposite side walls of the second guide groove.

[0021] The mounting portion further comprises a mounting block fixed on the mounting post;

[0022] The connecting member is fixed on the mounting block.

[0023] The connecting piece is a connecting plate;

[0024] The connecting plate is in a Γ shape; the horizontal portion of the connecting plate is fixed on the mounting block; the vertical portion of the connecting plate is suitable for fixing the workpiece to be processed;

[0025] The matching piece is fixed on a side plate surface of the vertical portion of the connecting plate.

[0026] Also includes a power supply structure;

[0027] The power supply structure comprises:

[0028] A power supply device arranged along the suspension chain;

[0029] At least one power connection device is provided in one-to-one correspondence with the connection member and in linkage; the power connection device is suitable for electrically connecting the workpiece to be processed with the power supply device.

[0030] The power connection device is slidably arranged on the power supply device;

[0031] The power supply structure also includes:

[0032] The toggle member is arranged corresponding to the power connection device, one end of which is fixed on the connecting member and the other end is abutted against the power connection device; the toggle member is suitable for driving the power connection device to move with the connecting member.

[0033] The present invention provides a workpiece processing system, comprising the above-mentioned transport structure.

[0034] The technical solution of the present invention has the following advantages:

[0035] 1. The transport structure provided by the present invention includes a frame, at least one connecting member, a suspension conveyor arranged on the frame, and a supporting guide structure arranged in parallel along the suspension chain of the suspension conveyor. The connecting member is connected to the suspension chain and movably supported on the supporting guide structure. It is driven by the suspension chain to move along the supporting guide structure. The connecting member connects the workpiece to be processed and bears the weight of the connecting member. A supporting guide structure is set up independently of the suspension conveyor. The workpiece to be processed is hung on the supporting guide structure through the connecting member. The supporting guide structure bears the weight of the workpiece to be processed. The connecting member is connected to the suspension chain and moves with the suspension chain, driving the workpiece to be processed to move along the supporting guide structure. The weight of the workpiece to be processed will not act on the suspension chain, thereby ensuring the service life of the suspension chain.

[0036] 2. The transport structure provided by the present invention has a supporting guide structure and a suspension chain extending in the same direction, and the supporting guide structure and the suspension chain are spaced apart in the horizontal direction. When the size of the workpiece to be processed changes or the spacing between two adjacent workpieces to be processed changes, the turning radius when turning on the transport line needs to be adaptively adjusted, otherwise it is easy for two adjacent workpieces to be processed to collide with each other or get stuck together at the turning point, causing the line to fail to operate normally. The connecting member is connected across the suspension chain and the supporting guide structure. By setting the distance between the supporting guide structure and the suspension chain, the turning radius of the workpiece to be processed hung below the supporting guide structure on the transport line is changed. There is no need to change the structure and position of the suspension conveyor, and only the horizontal position of the supporting guide structure arranged in parallel needs to be adjusted. The adjustment cost is low and the application range is wide. That is, due to the existence of the supporting guide structure, the workpiece to be processed can be suspended outward away from the center of the suspension chain, so that there is no interference between the workpieces when making a 90-degree or 180-degree turn. The operating radius of the supporting and guiding structure is larger than the operating radius of the suspension chain, and the overall circumference of the supporting and guiding structure is larger than the circumference of the suspension chain. Therefore, compared with directly setting it on the suspension chain, more tooling and fixtures can be evenly spaced on the supporting and guiding structure, and more workpieces can be processed per unit time, which greatly improves work efficiency.

[0037] 3. The transport structure provided by the present invention is provided with a second guide groove that is connected to the first guide groove of the suspension conveyor in parallel, the mounting column is inserted into the second guide groove, and a limiting wheel is provided on the mounting column to roll with the groove walls on both sides opposite to each other in the second guide groove. The second guide groove and the limiting wheel further limit the operation of the suspension chain, thereby improving the stability of the operation of the suspension chain and preventing the suspension chain from jumping in a direction perpendicular to the operation direction.

[0038] 4. The transport structure provided by the present invention comprises a power supply device, at least one power connection device and a toggle member. The power connection device and the power supply device are slidably matched. The toggle member is connected to the connecting member. When the connecting member moves, the toggle member abuts against the power connection device to drive the power connection device to slide on the power supply device to form an electrical connection. When the workpiece to be processed and the connecting member shake, the stability of the connection between the power connection device and the power supply device will not be affected due to the abutment arrangement of the toggle member and the power connection device.

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

[0049] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0050] Example 1

[0051] This embodiment provides a transport structure such as Figure 1 As shown, it includes a frame 1, at least one connecting member, a suspension conveyor arranged on the frame 1, and a supporting guide structure arranged in parallel along the suspension chain 3 of the suspension conveyor.

[0052] like Figure 3 As shown, in this embodiment, the suspension conveyor includes a first guide groove 6 and a second guide groove 7, the first guide groove 6 and the second guide groove 7 are connected up and down, and are separated by a partition 61 arranged on the groove walls on both sides of the opposite sides, so as to form two upper and lower parallel channels, and the suspension chain 3 is arranged along the first guide groove 6 below, and the suspension chain 3 is a conventional wheel-type suspension chain 3, such as Figure 4 As shown, a plurality of mounting parts are evenly spaced on the suspension chain 3, and the mounting parts include mounting posts 31 and mounting blocks 32. The mounting posts 31 are vertically fixed on the links of the suspension chain 3 and are inserted into the second guide groove 7. The mounting blocks 32 extending in the same direction as the second guide groove 7 are fixed on the mounting posts 31 for connection with the connecting member. At least one limiting wheel 33 is coaxially sleeved on the mounting posts 31. In this embodiment, each mounting post 31 corresponds to a limiting wheel 33, and the limiting wheel 33 is located between the mounting block 32 and the suspension chain 3.

[0053] The limiting wheel 33 rolls with the groove walls on both sides of the second guide groove 7. The second guide groove 7 and the limiting wheel 33 further limit the operation of the suspension chain 3, thereby improving the stability of the operation of the suspension chain 3 and preventing the suspension chain 3 from jumping perpendicular to the running direction.

[0054] The supporting guide structure extends in the same direction as the first guide groove 6 and is arranged at intervals in the horizontal direction. Figure 1 As shown, in this embodiment, the supporting guide structure is a guide rail 4 with a square cross-section. In this embodiment, the connecting member is a connecting plate 2 with a Γ-shaped side. The horizontal portion of the connecting plate 2 is fixed on the mounting block 32, and the lower end portion of the vertical portion is fixed to the drum 11, and the drum 11 is used to hold the workpiece to be processed.

[0055] like Figure 4 As shown, a mating piece that rolls with the guide rail 4 is provided on the plate surface of the vertical portion of the connecting plate 2, and the mating piece includes at least three rollers 5, which are distributed on both sides of the guide rail 4. In the present embodiment, four rollers 5 are provided, two of which are located above the guide rail 4 and roll with the upper guide rail 4, and the other two are located below the guide rail 4 and roll with the lower guide rail 4. The four rollers 5 are distributed on the four vertices of the isosceles trapezoid, and the rollers 5 on the upper and lower sides form a limit clamp for the guide rail 4. A guide rail 4 independent of the suspension conveyor is provided, and the workpiece to be processed is hung on the guide rail 4 through the connecting plate 2, and the guide rail 4 bears the weight of the workpiece to be processed. The connecting plate 2 is connected to the suspension chain 3 and moves with the suspension chain 3, while driving the workpiece to be processed in the drum 11 to run along the guide rail 4, and the weight of the workpiece to be processed will not act on the suspension chain 3, thereby ensuring the service life of the suspension chain 3.

[0056] The guide rail 4 and the suspension chain 3 are arranged in parallel and extend in the same direction, and the guide rail 4 and the suspension chain 3 are arranged at intervals in the horizontal direction. Figure 1 As shown, the turning radius when turning on the transport line needs to be adaptively adjusted, otherwise two adjacent rollers 11 may easily collide with each other or get stuck together at the turning point, causing the line to be unable to operate normally. The connecting plate 2 is bridged between the suspension chain 3 and the guide rail 4, changing the distance between the guide rail 4 and the suspension chain 3, and adjusting the length of the horizontal portion of the connecting plate 2 accordingly, thereby adjusting the turning radius required for the roller 11 hung under the guide rail 4 when turning on the transport line. There is no need to change the structure and position of the suspension conveyor, only the horizontal position of the parallel guide rails 4 needs to be adjusted, the adjustment cost is low, and the scope of application is wide.

[0057] The power supply structure includes a power supply device 8, at least one power connection device 9 and a toggle member 10 corresponding to the connection plate 2. Figure 2As shown, in this embodiment, the power supply device 8 includes a copper bar 81 arranged on the mounting frame, and the side of the copper bar 81 facing away from the power connection device 9 is connected to the external power supply. Four rows of copper bars 81 are arranged, all extending in the same direction as the suspension chain 3 and arranged above the side of the first guide slot 6 away from the drum 11. The power connection device 9 includes two groups of conductive posts 91, which are fixed on the same mounting plate, and the mounting plate is slidably arranged relative to the mounting frame, one end of one group of conductive posts 91 is slidably matched with the copper bar 81, and the other end is connected to the motor of the drum 11 through a wire; one end of the other group of conductive posts 91 is slidably matched with the copper bar 81, and the other end is connected to the workpiece to be processed in the drum 11 through a wire.

[0058] The toggle member 10 is arranged corresponding to the power connection device 9, one end of which is fixed on the connecting plate 2, and the other end is abutted on the mounting plate. When the connecting plate 2 moves with the suspension chain 3, the toggle member 10 abuts on the mounting plate to drive the conductive column 91 to slide on the copper bar 81, and the electrical connection is always maintained during operation. When the drum 11 and the connecting plate 2 shake, the stability of the connection between the power connection device 9 and the power supply device 8 will not be affected due to the abutment arrangement of the toggle member 10 and the power connection device 9. For example, the toggle member 10 is a toggle rod, and the power connection device 9 is slidably arranged on the mounting frame. The conductive column 91 is always connected to the copper bar 81. When the suspension chain 3 is running, the toggle rod is driven by the connecting plate 2 to toggle the power connection device 9 to move together, so as to prevent the power connection device 9 and the drum 11 from running out of sync and causing power failure. When the drum 11 shakes slightly, the toggle rod will not be separated from the power connection device 9, ensuring the stability of synchronous operation. The toggle member 10 can also be a spring column, one end of which is fixed on the connecting plate 2, and the other end is fixed on the mounting plate. Under normal conditions, the spring column has an elastic biasing force on the mounting plate toward the copper bus 81. Even if the drum 11 shakes or even the conductive column 91 is damaged, the conductive column 91 can still be forced to fully contact the copper bus 81 due to the presence of the elastic biasing force, thereby ensuring the stability of the electrical connection.

[0059] As a first replaceable implementation of Example 1, the extension directions of the guide rail 4 and the suspension chain 3 can be set at an angle, such as the projections of the guide rail 4 and the suspension chain 3 on the horizontal plane are parallel to each other, but the projections on the vertical plane are set at an angle. At this time, the connecting part is composed of a connecting plate 2 for installing a matching part and a chain with a certain extension length connecting the connecting plate 2 to the suspension chain 3. The suspension chain 3 runs on the guide rail 4 by dragging the connecting plate 2 by the chain, and the length of the chain is used to compensate for the changing spacing between the guide rail 4 and the suspension chain 3 during operation.

[0060] As a second replaceable implementation of Example 1, the guide rail 4 can be an I-shaped rail, and the grooves on both sides of the I-shape form the rail. The rollers 5 are correspondingly arranged in the grooves on both sides and clamped on the guide rail 4. At this time, the structure of the connecting plate 2 can be adaptively adjusted.

[0061] As a third alternative implementation of Example 1, the first guide groove 6 and the second guide groove 7 may be distributed left and right in the horizontal direction.

[0062] As a fourth alternative implementation of Example 1, the second guide groove 7 may not be provided, and correspondingly, the limiting wheel 33 may not be provided.

[0063] Example 2

[0064] This embodiment provides a workpiece processing system, including the transport structure in Embodiment 1.

[0065] 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.
