Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting and pulling technology, and more specifically, it relates to a pulling component for an automatic cutting and pulling device. Background Technology
[0002] Cutting electronic products is a processing step in the entire electronic manufacturing process. After the electronic components are processed, they are cut off from the material strip by a cutting device to obtain the finished electronic components, thus achieving the purpose of processing the electronic components.
[0003] Currently, since existing electronic components are cut from strips, the strips need to be pulled during the processing of electronic components. Existing material pulling assemblies generally use limiting components to limit the strips. Then, driven by the limiting components, the strips move together with the limiting components to ensure the normal operation of the processing.
[0004] However, after the material strip moves, there is no further limiting treatment on the material strip, and the material strip is in a relaxed state. When it is clamped and pulled again, the material pulling component will cause the relaxed material strip to retract, which will affect the normal operation of the material pulling work. Now, a material pulling component for an automatic cutting and pulling device is proposed to improve the existing problems. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a material pulling component for an automatic cutting and pulling device.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A material pulling component for an automatic cutting and pulling device includes a placement component. The top of the placement component is provided with a material pulling component, a limit component is provided on one side of the material pulling component, and a workpiece is provided at the middle position of the material pulling component.
[0008] The placement assembly includes a worktable, and a guide rail is provided on the top of the worktable.
[0009] The material pulling assembly includes a clamping block, and a limiting block is provided below the clamping block. The workpiece is positioned between the clamping block and the limiting block. The clamping block is used to assist in pulling the workpiece, and the limiting block is used to limit the workpiece on both sides.
[0010] The limiting component includes a fixing plate, which is disposed above the workpiece.
[0011] By adopting the above technical solution, the clamping block is U-shaped with the U-shaped opening facing downwards. When the clamping block contacts the workpiece, it can limit the transverse connecting parts on the workpiece, placing them in the middle position of the clamping block. At this time, the clamping block can limit the upper part of the workpiece. The limiting block is U-shaped, with two sets of baffles symmetrically arranged inside. The two sets of baffles are opposite to the bottom sides of the workpiece, limiting the bottom sides of the workpiece. The two sets of baffles inside the limiting block limit the lower part of the workpiece. Since the upper and lower parts of the workpiece are limited by the clamping block and the two sets of baffles of the limiting block respectively, and the width of the clamping block is less than the width between the two sets of baffles, the clamping block can move down to a position below the two sets of baffles. At this time, the two sets of baffles and the clamping block form a cross-shaped limiting on the workpiece, and the workpiece is limited within a certain range. Therefore, when the clamping block and the limiting block move as a whole, the workpiece moves with them.
[0012] The present invention is further configured such that: the material pulling assembly also includes a base, the base is disposed above the guide rail, the base and the guide rail are connected by a slider, a material pulling cylinder is disposed at the middle position of the guide rail, the output end of the material pulling cylinder is connected to a conveying shaft, and the conveying shaft is connected to the base through a connecting block.
[0013] The present invention is further configured such that: two sets of sliding rods are symmetrically arranged on the top of the base, a sliding block is arranged above the base, a top plate is arranged above the sliding block, the two sets of sliding rods respectively pass through the sliding block and are connected to the top plate, and the two sets of sliding rods are slidably connected to the sliding block respectively.
[0014] The present invention is further configured such that: a telescopic cylinder is provided on the top of the top plate, the output end of the telescopic cylinder passes through the top plate and is connected to the sliding block, a fixing block is provided on one side of the sliding block, the clamping block is provided at the bottom of the fixing block, and the limiting block is provided at the top of the base.
[0015] The present invention is further configured such that: the limiting component also includes a mounting block, the mounting block is disposed on the top of the guide rail, the top of the mounting block is provided with a bracket, and the bracket is configured to be inverted U-shaped.
[0016] The present invention is further configured such that: two sets of adjusting cylinders are symmetrically arranged at the middle position of the bracket, and each set of adjusting cylinders has an output shaft at its output end.
[0017] The present invention is further configured such that: the two sets of output shafts respectively pass through the bracket and are connected to the fixing plate, and the two sets of output shafts are respectively slidably connected to the bracket.
[0018] In summary, this application includes at least one of the following beneficial technical effects:
[0019] The limiting component limits the workpiece after it has been pulled, reducing the impact of the pulling component on the workpiece during movement and making it easier for the pulling component to pull the workpiece again. Attached Figure Description

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0031] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0032] Please see Figure 1-6 The present invention provides the following technical solution:
[0033] Example 1, see Figure 1A material pulling component for an automatic cutting and pulling device includes a placement component 1. A material pulling component 2 is provided on the top of the placement component 1, a limit component 3 is provided on one side of the material pulling component 2, and a workpiece 4 is provided in the middle of the material pulling component 2.
[0034] In practical applications, a cutting device is provided on the side of the material pulling assembly 2 away from the limiting assembly 3. After the cutting device cuts the workpiece 4, the material pulling assembly 2 pulls the workpiece 4 to move the position of the workpiece 4, so that the cutting device can process the next section of the workpiece 4.
[0035] See Figure 2 The placement component 1 includes a worktable 11, and a guide rail 12 is provided on the top of the worktable 11.
[0036] See Figure 2 and Figure 5 The material pulling assembly 2 includes a clamping block 27, and a limiting block 28 is provided below the clamping block 27. The workpiece 4 is positioned in the middle between the clamping block 27 and the limiting block 28. The clamping block 27 is used to assist in pulling the workpiece 4, and the limiting block 28 is used to limit the two sides of the workpiece 4.
[0037] See Figure 2 and Figure 5 The material pulling assembly 2 also includes a base 21, which is located above the guide rail 12. The base 21 and the guide rail 12 are connected by a slider. A material pulling cylinder 26 is located in the middle of the guide rail 12. The output end of the material pulling cylinder 26 is connected to a conveying shaft, which is connected to the base 21 through a connecting block.
[0038] See Figure 5 and Figure 6 Two sets of sliding rods 22 are symmetrically arranged on the top of the base 21. A sliding block 23 is arranged above the base 21. A top plate 25 is arranged above the sliding block 23. The two sets of sliding rods 22 pass through the sliding block 23 and are connected to the top plate 25 respectively. The two sets of sliding rods 22 are slidably connected to the sliding block 23 respectively.
[0039] See Figure 5 and Figure 6 A telescopic cylinder 24 is provided on the top of the top plate 25. The output end of the telescopic cylinder 24 passes through the top plate 25 and is connected to the sliding block 23. A fixing block 29 is provided on one side of the sliding block 23. A clamping block 27 is provided at the bottom of the fixing block 29. A limiting block 28 is provided at the top of the base 21.
[0040] See Figure 4 The clamping block 27 is U-shaped with the U-shaped opening facing downwards. When the clamping block 27 contacts the workpiece 4, the clamping block 27 can limit the transverse connecting piece on the workpiece 4, so that the transverse connecting piece is placed in the middle position of the clamping block 27. At this time, the clamping block 27 can limit the upper part of the workpiece 4.
[0041] See Figure 5 and Figure 6 The limiting block 28 is configured as a U-shaped structure. Two sets of baffles are symmetrically arranged inside the limiting block 28. The two sets of baffles are opposite to the bottom sides of the workpiece 4. The two sets of baffles can limit the bottom sides of the workpiece 4. The two sets of baffles inside the limiting block 28 limit the bottom of the workpiece 4.
[0042] Since the workpiece 4 is limited above and below by two sets of baffles, clamping block 27 and limiting block 28 respectively, and the width of clamping block 27 is less than the width between the two sets of baffles, clamping block 27 can move down to a position below the two sets of baffles. At this time, the two sets of baffles and clamping block 27 form a cross-shaped limit on workpiece 4, and workpiece 4 is limited within a certain range. Therefore, when clamping block 27 and limiting block 28 move as a whole, workpiece 4 follows them to achieve positional movement.
[0043] The specific process of the material pulling assembly 2 pulling the workpiece 4 is as follows:
[0044] First, the telescopic cylinder 24 is activated. Driven by the telescopic cylinder 24, the sliding block 23 moves down along the two sets of sliding rods 22. When the clamping block 27 moves down to the limit of the transverse connecting part of the workpiece 4, the telescopic cylinder 24 continues to work, driving the clamping block 27 to continue to move down. At this time, due to the two sets of baffles inside the limit block 28 limiting the bottom of both sides of the workpiece 4, the workpiece 4 enters the interior of the clamping block 27 as the clamping block 27 gradually moves down. The clamping block 27 can limit the workpiece 4, and the telescopic cylinder 24 stops working. At this time, the pulling cylinder 26 is activated. The pulling cylinder 26 drives the slider and the base 21 to move horizontally. The limit block 28, sliding rod 22, sliding block 23, output shaft 35 and clamping block 27 at the top of the base 21 move horizontally with it. At the same time, since the workpiece 4 is limited by the clamping block 27, the workpiece 4 moves horizontally with the clamping block 27, and finally the position of the workpiece 4 is adjusted.
[0045] After the workpiece 4 has moved once, the telescopic cylinder 24 is activated to work in reverse, and the clamping block 27 can release the workpiece 4, so that the material pulling assembly 2 can pull it up again.
[0046] Before the workpiece 4 moves to a new position, it is processed by a cutting device to separate the electronic components for collection. The cutting device generally consists of a hydraulic cylinder, an upper mold, a lower mold, and a cutter. Driven by the hydraulic cylinder, the upper mold and the lower mold cooperate, and the cutter set on the upper mold separates the electronic components from the workpiece 4, thus realizing the processing of the electronic components.
[0047] Before the electronic components are cut, they are conveyed by a conveyor roller mechanism, which includes roller groups and a drive mechanism. Driven by the drive mechanism, the roller groups convey the products. The electronic products are in the same position on the material belt. Therefore, the length of the products conveyed by the conveyor roller mechanism is consistent each time, and thus the position of the workpiece 4 reaching the clamping block 27 is consistent. The clamping block 27 can limit the workpiece 4.
[0048] After the workpiece 4 has moved to a new position, it is necessary to limit the workpiece 4 to reduce the possibility that the workpiece 4 will move with the material pulling assembly 2 in one displacement.
[0049] By setting the limiting component 3, the workpiece 4 can be limited after its position is moved, reducing the possibility of the workpiece 4 moving again.
[0050] See Figure 2 and Figure 4 The limiting component 3 includes a fixing plate 33, which is disposed above the workpiece 4.
[0051] See Figure 2 and Figure 4 The limiting component 3 also includes a mounting block 31, which is disposed on the top of the guide rail 12. A bracket 32 is disposed on the top of the mounting block 31, and the bracket 32 is shaped as an inverted U.
[0052] See Figure 2 and Figure 4 Two sets of adjusting cylinders 34 are symmetrically arranged in the middle of the bracket 32, and each set of adjusting cylinders 34 has an output shaft 35 at its output end.
[0053] See Figure 2 and Figure 4 Two sets of output shafts 35 pass through the bracket 32 and are connected to the fixed plate 33 respectively, and the two sets of output shafts 35 are slidably connected to the bracket 32 respectively.
[0054] After workpiece 4 completes one shift, two sets of workpiece 4 are started. The two sets of workpiece 4 drive the fixed plate 33 to move down through the two sets of output shafts 35 respectively. The downward movement of the fixed plate 33 limits the workpiece 4 and reduces the possibility of workpiece 4 shifting.
[0055] In practical applications, when the material pulling assembly 2 pulls the material, the fixed plate 33 is positioned away from the workpiece 4 under the action of the two sets of adjusting cylinders 34. The workpiece 4 can move along the bottom of the fixed plate 33 without affecting the normal operation of the material pulling work. After the material pulling assembly 2 finishes pulling the material, the fixed plate 33 moves to the top of the workpiece 4 under the action of the two sets of adjusting cylinders 34. The fixed plate 33 limits the workpiece 4. At this time, the material pulling assembly 2 can release the workpiece and then pull the material again. Since the workpiece 4 is limited by the fixed plate 33 and will not move with the material pulling assembly 2, the material pulling work can proceed normally.
[0056] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
