Description

Technical Field

[0001] The utility model relates to the technical field of springs, in particular to a spring material taking and releasing mechanism. Background Art

[0002] The 3C industry refers to the information and home appliance industry that integrates the three major technological products of computers, communications, and consumer electronics, and covers a very wide range.

[0003] Currently, a type of spring used in electronic devices within the 3C industry has a minimum length of 1.1mm and a radius of 0.5mm, while its maximum length is 2.25mm and its radius is 1.05mm. Currently, the market typically uses a combination of circular and linear vibration feed methods for loading this type of spring. A smaller number of spring feeders invert the spring tray, allowing it to fall onto a turntable covered with fine needles. A gripper assembly then grabs the spring from the turntable for loading. While this traditional method can successfully load springs, it still presents the following challenges:

[0004] 1. The existing combination of a vibrating plate and a reclaiming mechanism for feeding generally has low yield and utilization rates. Due to the physical and external characteristics of the springs, it is impossible to avoid or resolve common problems such as spring entanglement and spring jamming in the direct vibration channel during feeding. This requires frequent manual intervention, reducing overall efficiency.

[0005] 2. Although the clamping jaw assembly is used to avoid the NG phenomenon of circular vibration + straight vibration feeding springs entangled with each other and blocking the feeding channel, the action process of the clamping jaw assembly is relatively cumbersome, and the method of grabbing the spring for feeding is also very limited. Installing the spring clamp in a small space is prone to interference with the product, and it cannot stably cover a more comprehensive range of usage scenarios.

[0006] 3. A vibration plate can basically only be adapted to one type of spring. The replacement cost is high and the compatibility is insufficient. It is not suitable for the current rapidly changing 3C industry. Utility Model Content

[0007] The utility model provides a spring material taking and releasing mechanism to solve the problems raised in the above background technology.

[0008] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0009] A spring material taking and releasing mechanism includes a slide cylinder, an L-shaped block is connected to the slide of the slide cylinder, a small cylinder is fixedly installed on the L-shaped block, the output end of the small cylinder is connected to a lifting block, the lifting block is slidably set on the L-shaped block, a picking and placing needle is provided on the lifting block, and a blocking block is connected to the short side of the L-shaped block, a through hole is opened on the surface of the blocking block from top to bottom, the center of the through hole and the center of the picking and placing needle are on the same vertical line, and the inner cavity of the through hole is adapted to the outer wall of the picking and placing needle.

[0010] Preferably, the bottom end of the needle is provided with a chamfer.

[0011] Preferably, the surface of the taking-and-placing needle is coated with diamond abrasive.

[0012] Preferably, the diameter of the removal needle is slightly larger than the inner diameter of the spring.

[0013] Preferably, the diameter of the through hole is slightly larger than the diameter of the needle for taking and placing, and the diameter of the through hole is slightly smaller than the outer diameter of the spring.

[0014] Preferably, a guide rail is fixedly mounted on the surface of the L-shaped block, a slide is slidably mounted on the guide rail, and the slide is fixedly mounted on the lifting block.

[0015] Preferably, a positioning groove is provided at one end of the lifting block, the top end of the needle is arranged in the positioning groove, and a positioning block is fixedly installed at one end of the lifting block, and the needle is fixed in the positioning groove through the positioning block.

[0016] Preferably, a connecting plate is connected to one side of the slide cylinder.

[0017] Preferably, a partition is fixedly mounted on the slide of the slide cylinder, and the L-shaped block is fixedly mounted on the partition.

[0018] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0019] In the utility model, the lifting block and the picking and placing needle are driven down by the operation of a small cylinder, so that the picking and placing needle can be inserted into the spring, and then the spring is lifted up in conjunction with the contraction and reset of the small cylinder. When the lifting block and the picking and placing needle are continued to be driven up by the small cylinder, the spring can come into contact with the blocking block and fall off, prompting the spring to be placed in the product, completing the loading work without manual intervention, avoiding the problem of spring feeding being entangled with each other and blocking the channel, and also solving the problem of inconvenience in feeding with the clamp and easy interference with the product.

[0020] In the utility model, by replacing the blocking block on the L-shaped block and correspondingly processing the positioning groove on the lifting block, the positioning groove can be fixed with a pick-up and placement needle corresponding to different types of springs, and then the pick-up and placement needle and the blocking block are replaced according to the spring model, so that the replaced picking and placement mechanism can realize the picking and placement of springs of different models, meeting normal use. Compared with the replacement of the existing vibration plate, this type of replacement has a lower cost and is suitable for use by manufacturers.

[0021] In summary, the utility model has a simple structure, can flexibly deploy springs for taking and placing, and does not require manual intervention during the production process, is highly efficient, and meets the assembly quality and production capacity of electronic equipment; at the same time, when changing models, the replacement cost is low, and it has certain marketability.

[0030] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example

[0032] like Figure 1-7 As shown, the utility model provides a spring material taking and releasing mechanism, including a slide cylinder 1, an L-shaped block 2 is connected to the slide of the slide cylinder 1, a small cylinder 3 is fixedly installed on the L-shaped block 2, and the output end of the small cylinder 3 is connected to a lifting block 4, the lifting block 4 is slidably set on the L-shaped block 2, a picking and placing needle 5 is set on the lifting block 4, and a blocking block 6 is connected to the short side of the L-shaped block 2, and a through hole is opened on the surface of the blocking block 6 from top to bottom, the center of the through hole and the center of the picking and placing needle 5 are on the same vertical line, and the inner cavity of the through hole is adapted to the outer wall of the picking and placing needle 5.

[0033] Furthermore, the spring picking and unloading mechanism proposed in this solution can be flexibly assembled into multiple groups of picking and unloading mechanisms according to the number of springs to be loaded during actual use, and each group of picking and unloading mechanisms adopts the same structure and is controlled by an independent slide cylinder 1. The structure is simple and can meet different usage scenarios. At the same time, different types of spring picking mechanisms can also be incorporated into a set of picking mechanisms. The usage is flexible and varied, and will not affect the quality and production capacity of the assembly.

[0034] It should be emphasized that when multiple sets of material taking and placing mechanisms are assembled and used, although the blocking block 6 has the same structure, it needs to be changed in size according to the actual usage scenario. After the size change, the center of the through hole is still on the same vertical line as the center of the taking and placing needle 5, which is conducive to the taking and placing of the spring.

[0035] In this embodiment, the bottom end of the picking and placing needle 5 is provided with a chamfer, the surface of the picking and placing needle 5 is plated with diamond abrasive, and the diameter of the picking and placing needle 5 is slightly larger than the inner diameter of the spring.

[0036] Furthermore, a chamfer is provided at the bottom end of the picking and placing needle 5, so that the picking and placing needle 5 can be accurately inserted into the inner side of the spring after it is lowered, and the diameter of the picking and placing needle 5 is slightly larger than the inner diameter of the spring, which can better control the degree of deformation of the spring after being inserted, and avoid causing irreversible deformation that affects the function of the spring; and the surface of the picking and placing needle 5 is coated with corundum, which is conducive to the picking and placing needle 5 having sufficient friction to lift the spring, and it will not fall during the displacement of the manipulator. The action is simple, direct, stable, efficient and fast.

[0037] In this embodiment, the diameter of the through hole is slightly larger than the diameter of the removal needle 5 , and the diameter of the through hole is slightly smaller than the outer diameter of the spring.

[0038] Furthermore, the diameter of the through hole is slightly larger than the diameter of the picking and placing needle 5, which is beneficial for the small cylinder 3 to work and push the lifting block 4 down, so that the picking and placing needle 5 can extend through the through hole and descend to the acupuncture point of the spring material tray 12 to insert the spring; and the diameter of the through hole is slightly smaller than the outer diameter of the spring, so that when the small cylinder 3 drives the lifting block 4 to rise and the picking and placing needle 5 retracts, the spring will be squeezed and fall off when it touches the blocking block 6, ensuring that the spring can fall off smoothly when the material is discharged.

[0039] It should be emphasized that: after the needle 5 pierces the spring, the small cylinder 3 works to drive the needle 5 to retract. The needle tip of the needle 5 must first stay at the bottom of the blocking block 6 to expose a part, and the length of the exposed part is determined according to the size of the spring. Then, when loading, the small cylinder 3 continues to work to drive the needle 5 to retract. In this way, when the needle 5 is retracted, the spring can resist the blocking block 6 to separate from the needle 5. During this period, the needle 5 can provide stable guiding support for the spring when it is separated, thereby ensuring the success rate and stability of the spring when discharging.

[0040] In this embodiment, a guide rail 7 is fixedly mounted on the surface of the L-shaped block 2 , a slide 8 is slidably mounted on the guide rail 7 , and the slide 8 is fixedly mounted on the lifting block 4 .

[0041] Combine Figure 1 As shown, further, the design of the guide rail 7 and the slide 8 is adopted, so that the lifting block 4 can stably drive the needle 5 to rise or fall.

[0042] In this embodiment, a positioning groove is provided at one end of the lifting block 4, and the top end of the needle 5 is arranged in the positioning groove, and a positioning block 9 is fixedly installed at one end of the lifting block 4, and the needle 5 is fixed in the positioning groove through the positioning block 9.

[0043] Combine Figure 2 As shown, further, after the positioning block 9 is fixedly installed on the lifting block 4 by bolts, the needle 5 can be lowered and fixed. Conversely, when the bolts are loosened and the positioning block 9 is loosened, the needle 5 can be replaced, making the replacement of the needle 5 simple and convenient.

[0044] It should be emphasized that: when taking and placing springs of different models, by replacing the blocking block 6 on the L-shaped block 2 and correspondingly processing the positioning groove on the lifting block 4, the positioning groove can be used to install and fix the picking and placing needle 5 corresponding to the different models of springs, and then the picking and placing needle 5 and the blocking block 6 are replaced according to the spring model, so that the replaced picking and placing mechanism can realize the picking and placing of springs of different models, meeting normal use. Compared with the replacement of the existing vibration plate, this type of replacement has a lower cost and is suitable for use by manufacturers.

[0045] In this embodiment, a connecting plate 10 is connected to one side of the slide cylinder 1 .

[0046] Combine Figure 4 and Figure 6 As shown, the slide cylinder 1 is conveniently fixed on the robot arm through the connecting plate 10. Conversely, when replacing a different type of material taking and unloading mechanism, the connecting plate 10 can be disassembled for replacement, which is simple and convenient.

[0047] In this embodiment, a partition 11 is fixedly mounted on the slide of the slide cylinder 1, and the L-shaped block 2 is fixedly mounted on the partition 11. Its main function is to arrange the space reasonably and make full use of the space according to actual usage.

[0048] The working principle and use process of this utility model:

[0049] Before use, there is a spring tray 12 filled with spring products, and the spring tray 12 filled with spring products can be transported on a conveying device. At the same time, a station for placing electronic equipment products is set on one side of the conveying device. The conveying device and the product station are well-known technologies in the art and will not be described in detail herein.

[0050] When in use, the connecting plate 10 is fixedly connected to the manipulator, and the shooting positioning device on the manipulator is used to control the position, so that the through hole on the blocking block 6 corresponds to the spring product in the spring material tray 12. As a result, after the slide cylinder 1 works to push the partition 11 down, the bottom of the L-shaped block 2 is located above the spring material tray 12, and then the small cylinder 3 works to push the lifting block 4 down, and the picking and placing needle 5 can pass through the through hole on the blocking block 6 and penetrate into the spring. As a result, when the lifting block 4 and the picking and placing needle 5 are driven to rise by the small cylinder 3, the picking and placing needle 5 coated with diamond can use its sufficient friction to bring the spring When the lifting block 4 and the picking needle 5 are lifted up, the spring can come off the blocking block 6, prompting the spring to be placed in the product, thus completing the loading work without manual intervention. This avoids the problem of spring feeding being entangled with each other and blocking the channel, and also solves the problem of inconvenience in feeding with the clamp and easy interference with the product.

[0051] It should be noted that this article only provides physical structural protection for the spring loading and unloading mechanism. This solution does not improve the existing conveying equipment, robotic arms, and camera positioning devices. These various devices are well-known technologies to those skilled in the art, so this solution will not elaborate on them.
