Description

Technical Field

[0001] The present application relates to the technical field of elastic element assembly, and in particular to an elastic element assembly mechanism and elastic element assembly equipment. Background Art

[0002] In the assembly and production process of many types of products, springs often need to be installed in the product. For example, when assembling a high-voltage relay of a handheld charging gun for a car, a spring needs to be installed from bottom to top into a certain part.

[0003] The prior art spring assembly equipment usually uses a vibration plate to load the spring, and then the cylinder and the push rod directly install the spring. The cylinder and the push rod install the spring into the product. However, since the spring itself has the characteristics of being light in weight and automatically rebounding after being compressed, it is difficult to assemble the spring into the product using the existing spring assembly equipment. For example, the spring will automatically shift and rebound during assembly, causing the spring to be easily misplaced and unable to be installed in the spring installation hole of the product, thereby reducing the success rate of successfully assembling the spring into the product at one time. Summary of the invention

[0040] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0041] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0042] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0043] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0044] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0045] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0046] As described in the background art, in the assembly and production process of many types of products, elastic elements are often required to be installed in the product. For example, when assembling a high-voltage relay of a handheld charging gun for a vehicle, an elastic element such as a spring needs to be installed from bottom to top into a certain part.

[0047] The elastic element assembly equipment in the prior art usually uses a vibration plate to load the elastic element, and then the cylinder and the push rod directly install the elastic element. The cylinder and the push rod install the elastic element into the product. However, since the elastic element itself has the characteristics of being light in weight and automatically rebounding after being compressed, it is difficult to assemble the elastic element into the product using the existing elastic element assembly equipment. For example, the elastic element will automatically shift and rebound during assembly, causing the elastic element to be easily misaligned with the elastic element installation hole of the product and cannot be installed into the product, thereby making the success rate of the elastic element being successfully assembled into the product at one time low.

[0048] To this end, the present application provides an elastic element assembly mechanism, an elastic element assembly device including the elastic element assembly mechanism, and an elastic element assembly method using the elastic element assembly device and the elastic element assembly mechanism, which are used to assemble the elastic element from bottom to top into a product located at an assembly station, so as to improve the success rate of successfully assembling the elastic element into the product in one go.

[0049] The following takes the product to be assembled with elastic elements as a part used in a high-voltage relay of an electric vehicle charging gun as an example to explain the structure of the elastic element assembly device, the elastic element assembly mechanism, and the steps of the elastic element assembly method in the present application. It can be understood that in other embodiments, the elastic element assembly device, the elastic element assembly mechanism, and the elastic element assembly method of the present application are not limited to assembling elastic elements in assembling high-voltage relays, but can also be used to assemble elastic elements from bottom to top into a certain part during the assembly process of any product, and can also be used to install elastic elements other than springs into parts, which is not limited here.

[0050] See also Figure 1 , Figure 1A schematic diagram of an elastic element assembly device 10 in an embodiment of the present application is shown. The elastic element assembly device 10 provided in an embodiment of the present application includes a product conveying line (not shown in the figure), a carrier 120 assembly 100, an elastic element assembly mechanism 200, a positioning mechanism 300, a detection mechanism 400 and a transfer mechanism 500. The carrier assembly 100 is arranged on the product conveying line for carrying products; the product conveying line is used to convey the carrier assembly 100 carrying products through an assembly station 101; the elastic element assembly mechanism 200 and the positioning mechanism 300 are respectively arranged on opposite sides of the assembly station 101 along the first horizontal direction (i.e., the X direction shown in the figure); the elastic element assembly mechanism 200 is used to assemble the elastic element into the product from bottom to top at the above-mentioned assembly station 101 when the carrier assembly 100 carries the product through the assembly station 101; the positioning mechanism 300 is used to assemble the elastic element at the assembly station 101 when the elastic element assembly mechanism 200 assembles the elastic element , forming an installation gap with the elastic element assembly mechanism 200 at the assembly station 101 to limit the elastic element in the installation gap and prevent the elastic element from shifting at will when being assembled; the detection mechanism 400 is arranged next to the elastic element assembly mechanism 200, and is used to detect the size specifications of a batch of several elastic elements before the elastic elements are assembled into the product (for example, to detect the height, diameter and other dimensions of the elastic elements) to avoid mixing elastic elements with unqualified size specifications in the batch of elastic elements; the transfer mechanism 500 is used to transfer the elastic elements to the elastic element assembly mechanism after the elastic elements have been inspected to wait for being assembled into the product.

[0051] It is understandable that the product conveyor line can be a turntable that can rotate around its own central axis to drive the carrier assembly 100 carrying the product to cyclically pass through the assembly station 101, or the product conveyor line can also be along a second horizontal direction ( Figure 1 The linear module 510 or conveyor belt extending in the Y direction (as shown in the figure) can transport the carrier assembly 100 carrying the product through the assembly station 101 along the second horizontal direction, which is not limited here.

[0052] See also Figure 1 and Figure 2In one embodiment, the elastic element assembly mechanism 200 includes a first base 210 and a pushing assembly 220. The pushing assembly 220 is arranged on the first base 210, and includes a mounting seat 221, a sleeve 222, a push rod 223 and a first driving member 224. The sleeve 222 is arranged on the mounting seat 221 at one end close to the assembly station 101, and is used to accommodate the elastic element. The first driving member 224 is spaced apart from the sleeve 222 along a first horizontal direction. The push rod 223 is connected to the first driving member 224 and can be movably inserted in the sleeve 222. Under the drive of the first driving member 224, the push rod 223 can move along the first horizontal direction to push the elastic element in the sleeve 222 out of the sleeve 222 to the assembly station 101, so that the elastic element can be assembled into the product from bottom to top.

[0053] Specifically, see Figure 2 and Figure 3 The mounting seat 221 is a frame structure, including a first mounting plate 2211 and a second mounting plate 2212 arranged at intervals in the vertical direction. The first mounting plate 2211 is arranged below the second mounting plate 2212 and is connected to the second mounting plate 2212 through a plurality of columns 2213, so that a mounting position is formed between the first mounting plate 2211 and the second mounting plate 2212. The sleeve 222 is installed on the first mounting plate 2211 and is located on one side of the mounting position in the first horizontal direction. The first driving member 224 is installed on the second mounting plate 2212 and is located on the other side of the mounting position in the first horizontal direction. The push rod 223 is penetrated through the mounting position, thereby saving space and making the structure of the pushing assembly 220 more compact.

[0054] In the structure of the sleeve 222, the sleeve 222 is provided with a receiving groove and a mounting hole 222a. The receiving groove passes through the sleeve 222 at two opposite ends in the first horizontal direction and is connected to the mounting hole 222a. The mounting hole 222a is used for the elastic element to be placed in the sleeve 222. The push rod 223 is movably inserted in the receiving groove. The height of the receiving groove in the vertical direction is less than the height of the elastic element in the natural state. When the push rod 223 moves along the first horizontal direction, the push rod 223 can push the elastic element accommodated in the mounting hole 222a into the receiving groove and be compressed by the top wall of the receiving groove. Without the need for additional manual operation or additional mechanical structure, the elastic element can be always in a compressed state before being assembled into the product, thereby saving labor and simplifying the structure of the equipment.

[0055] Furthermore, in order to prevent the elastic element from suddenly rebounding to a natural state after being pushed out of the sleeve 222 by the push rod 223, which makes it difficult to assemble into the product, the sleeve 222 is slidably arranged on the mounting seat 221, and the pushing assembly 220 also includes a second driving member 225 arranged on the mounting seat 221, and the sleeve 222 is connected to the second driving member 225, and the second driving member 225 can drive the sleeve 222 to move relative to the mounting seat 221, so that when the push rod 223 pushes a part of the elastic element from one end of the sleeve 222 to the assembly station 101, the edge of the elastic element still abuts against the top wall of the accommodating groove and is still in a compressed state. At this time, by withdrawing the sleeve 222 relative to the push rod 223 away from the assembly station 101, the elastic element can be gradually and slowly exposed to the outside of the sleeve 222 and gradually rebound, thereby solving the problem that the elastic element suddenly rebounds to a natural state, which makes it difficult to assemble into the product.

[0056] Please continue reading Figure 3 Optionally, the push assembly 220 further includes a third driving member 226 disposed on the first base 210, the mounting seat 221 is slidably disposed on the first base 210 and connected to the third driving member 226, and the third driving member 226 can drive the mounting seat 221 to move along the first horizontal direction, so that the mounting seat 221 can drive the sleeve 222, the push rod 223, the first driving member 224 and the second driving member 225 to move along the first horizontal direction as a whole. In this way, on the one hand, the sleeve 222 can be close to the assembly station 101, so that the elastic element can be loaded into the product at an accurate position; on the other hand, the sleeve 222 can prevent the carrier assembly 100 from continuing to move due to inertia, so that the carrier assembly 100 can accurately stop at the assembly station 101 when being transported by the product conveyor line, avoiding affecting the success rate of the elastic element being loaded into the product due to inaccurate stopping position.

[0057] For further information, see Figure 2The push assembly 220 has two push assemblies 220, which are spaced apart along the second horizontal direction, and the apertures of the mounting holes 222a on the sleeves 222 of the two push assemblies 220 are different. The elastic element assembly mechanism 200 also includes a second base 230 and a fourth driving member (not shown in the figure), the first base 210 is slidably disposed on the second base 230 and connected to the fourth driving member, and the fourth driving member is used to drive the first base 210 to reciprocate along the second horizontal direction, so that the first base 210 can drive the two push assemblies 220 to reciprocate along the second horizontal direction together. In this way, the two pushing components 220 arranged on the first base 210 can be alternately aligned with the assembly station 101 in the first horizontal direction, so that when elastic elements of different sizes need to be assembled, the corresponding pushing components 220 can be conveniently switched to be aligned with the assembly station 101, so that the corresponding pushing components 220 can load the elastic elements of specific specifications into the corresponding products, so that the elastic element assembly mechanism 200 can be compatible with a variety of products and a variety of elastic elements, realize automatic model change of the production line, reduce customer production costs, and improve equipment utilization.

[0058] It is understandable that the number of pushing components 220 is not limited to two, but may be more. The aperture sizes of the mounting holes 222a in the multiple pushing components 220 are different, so that they can adapt to elastic elements of more specifications and sizes, so that elastic elements of various specifications and sizes can be installed in different products.

[0059] See also Figure 4 The positioning mechanism 300 includes a fifth driving member 310 and a push rod 320 connected to the fifth driving member 310. The push rod 320 is arranged relative to the sleeve 222 of the elastic element assembly mechanism 200 in the first horizontal direction. Under the drive of the fifth driving member 310, the push rod 320 can approach or move away from the sleeve 222 along the first horizontal direction. When the push rod 320 approaches the sleeve 222, an end of the push rod 320 away from the fifth driving member 310 can form an installation gap with an end of the sleeve 222 away from the first driving member 224 at the assembly station 101. In this way, when the elastic element is pushed out of the sleeve 222 by the push rod 223, the push rod 320 can abut against the elastic element, so that the elastic element is limited in the installation gap, preventing the elastic element from moving at will, so as to avoid the elastic element and the product from being misaligned, thereby ensuring that the elastic element can be smoothly installed in the product.

[0060] In the above embodiments, the first driving member 224 to the fifth driving member 310, and all driving members mentioned below may be driving sources such as a cylinder, an electric cylinder, etc., which are not limited here.

[0061] However, in some cases, when the fifth driving member 310 is a cylinder, since the output end of the cylinder only has an initial position and a fixed end position when moving, when the size of the elastic element changes, the output end of the cylinder cannot change the end position to limit the elastic elements of different sizes.

[0062] In order to solve this problem, in an improved embodiment, the output end of the fifth driving member 310 is provided with a sixth driving member 330, and the top rod 320 is connected to the output end of the sixth driving member 330. In this way, when the size of the elastic element changes, it is only necessary to drive the top rod 320 to move one position by the sixth driving member 330, so that the fifth driving member 310 can drive the sixth driving member 330 and the top rod 320 to move to different terminal positions, thereby being able to adapt to different types of elastic elements for limiting. In addition, a sensing element such as a photoelectric sensor can be installed at the output end of the fifth driving member 310 to detect whether the top rod 320 has returned to the initial position.

[0063] In terms of the structure of the carrier assembly 100, the carrier assembly 100 includes a support base 110 installed on the product conveying line and a carrier 120 connected to the support base 110. Figure 4 and Figure 5 As shown, the carrier 120 has a plurality of bearing surfaces 121 arranged at intervals, and the bearing surfaces 121 are used to bear products. When the products are placed on the carrier 120, they are suspended so that the push rod 320 and the sleeve 222 can extend into the carrier 120 and be located below the products, thereby positioning the carrier assembly 100 at the assembly station 101. In this way, when the push rod 223 pushes the elastic element out of the sleeve 222, the push rod 223 also extends into the carrier 120 and is located below the product, so that the elastic element can be loaded into the product from bottom to top.

[0064] Furthermore, in some embodiments, considering factors such as the overall design of the equipment and the product, when the carrier assembly 100 carrying the product arrives at the assembly station 101, the product must be at a certain height so that the elastic element can be installed in the product. Therefore, in order to ensure that each carrier assembly 100 passing through the assembly station 101 can be at a fixed height, refer to Figure 6The support seat 110 includes a first support plate 111 and a second support plate 112 arranged above the first support plate 111 at intervals, wherein the second support plate 112 is fixedly installed on the product conveying line, the first support plate 111 is movably connected to the second support plate 112 through a plurality of guide columns 113, the carrier 120 is arranged on the second support plate 112 and connected to the guide columns 113, and a jacking assembly 600 is also arranged below the carrier assembly 100. The jacking assembly 600 is arranged below the first support plate 111, and when the product conveying line conveys the carrier assembly 100 to the assembly station 101, the bottom surface of the first support plate 111 can abut against the jacking assembly 600, so that the first support plate 111 can rise in the vertical direction relative to the second support plate 112 and the product conveying line together with the guide columns 113 and the carrier 120 under the jacking of the jacking assembly 600. In this way, when each carrier assembly 100 is transported to the assembly station 101 by the product conveyor line, the carrier assembly 100 can be lifted to a fixed height position in the vertical direction under the support of the lifting assembly 600, so that the elastic element can be installed in the product at the above height position.

[0065] In a specific embodiment, the lifting assembly 600 includes a fixed seat 610 and a lifting member 620 arranged on the fixed seat 610. In the embodiment shown in the figure, the lifting member 620 is a roller rotatably mounted on the fixed seat 610, and the roller can rotate around its own center axis relative to the fixed seat 610. Correspondingly, along the conveying direction of the product conveyor line, and in the direction from the end of the first support plate 111 to the middle of the first support plate 111, the thickness dimension of the first support plate 111 in the vertical direction gradually increases.

[0066] In this way, when the carrier assembly 100 moves to the assembly station 101, based on the above-mentioned structure of the first support plate 111, the first support plate 111 will inevitably abut against the lifting member 620 and be lifted to a fixed height, thereby simplifying the structure and achieving lifting with a simple mechanical structure without the aid of a cylinder or electrical structure, thereby saving the production cost of the equipment.

[0067] In addition, in order to prevent the carrier assembly 100 from shaking up and down when it is installed on the product conveyor line because the second support plate 112 can move relative to the first support plate 111, an elastic element 114 is provided between the first support plate 111 and the second support plate 112 and is sleeved on the outer periphery of the guide column 113. The elastic element 114 is configured to provide an elastic force, and relies on the elastic force to abut against the first support plate 111 to prevent the first support plate 111 from moving in the vertical direction relative to the second support plate 112 when the product conveyor line conveys the carrier assembly 100, thereby preventing the carrier 120 from shaking up and down relative to the product conveyor line when being conveyed by the product conveyor line.

[0068] See also Figure 7 , is a schematic diagram of the structure of a detection mechanism 400 in an embodiment. In this embodiment, the detection mechanism 400 includes a machine platform 410 and a material transfer component 420 arranged on the machine platform 410. The machine platform 410 has an incoming material station 401 and a detection station 402 arranged at intervals. The detection station 402 is provided with a detection component 430. The material transfer component 420 is used to receive the elastic element at the incoming material station 401 and transfer the elastic element to the detection station 402, so that the elastic element can be detected by the detection component 430 to determine whether its size specifications are qualified.

[0069] Specifically, combined Figure 7 and Figure 8 As shown, the machine 410 includes a table body 411 and a stand 412 arranged on the table body 411, the material moving assembly 420 includes a seventh driving member 421 and a material moving member 422 connected to the seventh driving member 421, the seventh driving member 421 is arranged on the table body 411, the material moving member 422 is vertically penetrated in the stand 412, and can travel back and forth between the incoming material station 401 and the inspection station 402 under the drive of the seventh driving member 421.

[0070] Preferably, see Figure 8 The material moving member 422 has two material moving heads 4221 spaced apart in the horizontal direction. Each material moving head 4221 is used to position the elastic element, so that when one of the material moving heads 4221 receives the elastic element at the incoming material station 401, the other material moving head 4221 is located at the inspection station 402 to receive the inspection of the inspection component 430, thereby reducing waiting time and improving work efficiency.

[0071] Better yet, see Fig. 9 The material transfer head 4221 is a cylindrical hollow structure with a fixed column 4221a disposed inside. When the material transfer head 4221 receives the elastic element at the incoming material station 401, the elastic element can be sleeved on the fixed column 4221a, so that it can be positioned in the material transfer head 4221 without changing its position or tipping over, thereby avoiding the occurrence of inaccurate detection results.

[0072] As a further improvement, the incoming material station 401 is provided with an incoming material assembly 440, which has an incoming material pipe 441 extending in the vertical direction, and the incoming material pipe 441 is used for the elastic element to pass through, so that the elastic element can fall from the upper end of the incoming material pipe 441 along a fixed path to the material transfer head 4221 of the material transfer member 422, thereby preventing the elastic element from falling outside the material transfer head 4221. In the embodiment shown in the figure, there are two incoming material pipes 441, and the machine 410 is provided with an eighth driving member 442. The two incoming material pipes 441 are connected to the eighth driving member 442. Under the drive of the eighth driving member 442, the two incoming material pipes 441 can move in the horizontal direction, so as to be able to alternately align with the material transfer head 4221 located at the material transfer member 422 in the vertical direction, so that the elastic elements of two different specifications and sizes can be respectively inspected by the inspection assembly 430 to detect whether the elastic elements of each batch of specifications and sizes are mixed with elastic elements of unqualified size.

[0073] It is understandable that the number of the incoming pipes 441 is not limited and can be set as needed to enable the detection mechanism 400 to detect one or more batches of elastic elements.

[0074] As a further improvement, the output end of the seventh driving member 421 is connected to an L-shaped connecting plate 423, and the connecting plate 423 is provided with a ninth driving member 424, and the material moving member 422 is connected to the output end of the ninth driving member 424, so that the seventh driving member 421 can drive the ninth driving member 424 and the material moving member 422 to move back and forth between the incoming material station 401 and the inspection station 402 in the horizontal direction, and the ninth driving member 424 can also drive the material moving member 422 to move in the vertical direction, so as to achieve the desired effect. When the material transferring head 4221 receives the elastic element of the incoming material at the material receiving station 401, the ninth driving member 424 can drive the material transferring head 4221 to rise to approach the material receiving tube 441, thereby further ensuring that the elastic element of the incoming material can accurately fall into the material receiving tube, and when the material transferring head 4221 moves to the detection station 402, the ninth driving member 424 can drive the material transferring head 4221 to descend to avoid the detection component 430, thereby preventing the material transferring head 4221 from interfering with the detection component 430.

[0075] Alternatively, please continue to Figure 8A waste collection box 450 is also provided on the table body 411 of the machine 410. When the detection component 430 detects that a batch of elastic elements are mixed with elastic elements of unqualified sizes, the transfer mechanism 500 can put the elastic elements of unqualified size specifications into the waste collection box 450 for easy collection. When the size specifications of the elastic elements are qualified after detection, the transfer mechanism 500 transfers the elastic elements of qualified size specifications to the elastic element assembly mechanism 200 and puts them into the mounting hole 222a of the sleeve 222, so that the elastic elements can be installed into the product using the elastic element assembly mechanism 200 described in the above embodiment in the subsequent process.

[0076] See also Fig.10 In terms of the structure of the transfer mechanism 500, the transfer mechanism 500 includes a linear module 510 and a transfer assembly 520 movably arranged on the linear module 510. The transfer assembly 520 can move back and forth between the detection mechanism 400 and the elastic element assembly mechanism 200 under the drive of the linear module 510, so as to transfer the elastic element that has passed the detection from the detection mechanism 400 to the sleeve 222 of the elastic element assembly mechanism 200.

[0077] In a specific embodiment, see Fig.11 The transfer assembly 520 includes a tenth driving member 521 and a clamping jaw 522 connected to the tenth driving member 521. Under the drive of the tenth driving member 521, the clamping jaw 522 can move in the vertical direction to clamp the elastic element and place the elastic element into the mounting hole 222a of the sleeve 222; and the transfer assembly 520 also includes an eleventh driving member 523 arranged on the clamping jaw 522 and a pressure rod 524 connected to the eleventh driving member 523, so that the pressure rod 524 can be movably connected to the clamping jaw 522, and the eleventh driving member 523 is used to drive the pressure rod 524 to move relative to the clamping jaw 522. The clamping jaw 522 moves in the vertical direction, so that when the clamping jaw 522 places the elastic element into the mounting hole 222a of the sleeve 222, the pressing rod 524 can move in the vertical direction relative to the clamping jaw 522 and be inserted into the mounting hole 222a to compress the elastic element in the mounting hole 222a, thereby facilitating the push rod 223 not to interfere with the top wall of the receiving groove when pushing the elastic element into the receiving groove of the sleeve 222, thereby preventing the elastic element from causing irreversible bending deformation and avoiding damage to the elastic element due to interference with the top wall of the receiving groove.

[0078] It should be noted that, before the elastic element is assembled into the product, if it can be ensured that the size specifications of the elastic element are qualified, the elastic element assembly equipment 10 of the above embodiment may also only have the elastic element assembly mechanism 200 and the positioning mechanism 300, without having to have the detection mechanism 400 and the transfer mechanism 500. The specific settings can be made according to needs, and there is no special limitation here.

[0079] It can be seen that the elastic element assembly device 10 provided in the present application, through the above-mentioned design of the elastic element assembly mechanism 200, can realize the installation of the elastic element into the product from bottom to top in a step-by-step and gradual release manner, that is, firstly, the push rod 223 is used to push part of the elastic element out of the sleeve 222, so that the part pushed out of the sleeve 222 is exposed outside the sleeve 222, and the remaining part of the elastic element is still in contact with the top wall of the accommodating groove of the sleeve 222, so that the elastic element is still in a compressed state; then, the sleeve 222 is withdrawn relative to the push rod 223 in a direction away from the assembly station 101, so that the elastic element It is completely exposed from the sleeve 222 and rebounds, so that the elastic element can be installed into the product from bottom to top, and the elastic element can be always limited in position during the assembly process, preventing the elastic element from suddenly rebounding or being misaligned with the product, thereby helping to successfully install the elastic element into the product at one time, thereby improving the success rate of elastic element assembly, and improving the overall assembly efficiency and production quality of the product. It can also realize automatic model change of the elastic element, and is compatible with customers installing elastic elements into a variety of products and compatible with installing elastic elements of various specifications into products, effectively reducing production costs and improving equipment utilization.
