[0052] In the production process of the Pin needle spring commonly used in electronic products, the Pin needle spring needs to be taken out from the tray to prepare for the subsequent assembly of the Pin needle spring. The assembly of the Pin needle spring requires the Pin needle to be inserted into the mainboard product with the position accurate and downward, and then the Pin needle is sleeved into the mainboard component Rubber. At present, the solution to this process in the industry usually relies on manual assembly. First, the Pin needle spring is taken out from the tray, the PIN needle is downward, and then the Pin needle is assembled in the mainboard hole and sleeved into the Rubber product. This process has the problems of low efficiency of manual assembly, easy ejection of the Pin needle after assembly, high assembly precision of the Pin and the mainboard hole, and easy eye fatigue of the worker after long-time assembly.

[0053] To solve the above problems, the present application provides an assembly equipment, Figure 1 a perspective view of an embodiment of the assembly equipment provided by the present application; Figure 2 a perspective view of the material conveying mechanism in Figure 1 a perspective view of the turnover mechanism in Figure 3 a perspective view of the adjusting mechanism in Figure 1 an enlarged view of A in Figure 4 a perspective view of the assembly mechanism in Figure 1 a perspective view of the pickup part in Figure 5 an enlarged view of B in Figure 4 .

[0054] Please refer to Figures 1 to 3 , the assembly equipment 100 includes a machine base 1, a material conveying mechanism 2, a turnover mechanism 3, an adjusting mechanism 4 and an assembly mechanism 5, the machine base 1 is provided with a feeding station, a material taking station, an adjusting station and an assembly station; the material conveying mechanism 2 includes a material taking part 21 for picking up the needle spring, the material taking part 21 is movably arranged and has a movement stroke between the feeding station and the material taking station, for conveying the needle spring at the feeding station to the material taking station; the turnover mechanism 3 includes a turnover part 31 rotatably installed on the machine base 1, the turnover part 31 is used for turning over the needle spring conveyed by the material taking part 21, so that the needle of the needle spring faces downward; the adjusting mechanism 4 is used for adjusting the angle of the needle spring located at the adjusting station; the assembly mechanism 5 includes a pickup part 51 movably arranged, the pickup part 51 has a movement stroke between the material taking station and the assembly station, for picking up the needle spring on the adjusting part 41 to the assembly station, and the pickup part 51 also has a downward movement stroke, for inserting the needle of the needle spring into the insertion hole of the product at the assembly station in the downward movement stroke.​​

[0055] In the technical solution provided by the present invention, the picking part 21 picks up the ejector spring with the ejector pin facing upward when the material is received and transports it to the flipping mechanism 3 of the picking station. The flipping part 31 flips the transported ejector spring so that the ejector pin of the ejector spring faces downward, and then adjusts the angle of the ejector spring through the adjusting mechanism 4 so that the ejector pin can be adjusted to a suitable position for subsequent assembly. The picking part 51 picks up the ejector spring with the ejector pin facing downward and transports it to the assembly station. During the downward movement, the ejector pin of the ejector spring is inserted into the socket of the product at the assembly station, so as to provide an assembly device 100 that can accurately and efficiently realize automatic assembly of pin springs and products, thereby solving the problems of low manual operation efficiency and poor quality during the feeding and assembly of pin springs.

[0056] It should be noted that the ejector spring is an integrally formed structure, with a spring coil at its head and an ejector pin extending from the coil at its tail. The ejector pin is parallel to the coil's axis and eccentric to the center of the coil's cross-section. Therefore, when inserting the ejector pin, it must be adjusted to the preset position to ensure a precise fit between the ejector spring and the product's rubber.

[0057] Specifically, to facilitate clamping of the ejector spring and to enable the ejector spring to be initially positioned when flipped, in this embodiment, the flip portion 31 includes two clamping arms 311 that can be arranged to move away from and toward each other. The two clamping arms 311 are each provided with an arcuate concave surface on the side where they approach each other. The two arcuate concave surfaces enclose a clamping space for clamping the spring coil. It will be understood that the two arcuate concave surfaces are adapted to fit the spring coil of the ejector spring. When the flip portion 31 picks up the spring coil, the spring coil can be confined within the clamping space, thereby positioning it. Thus, after the flip portion 31 is flipped 180°, the ejector spring can be positioned in the predetermined x- and y-directions on the plane in which it is located, avoiding uncertainty in its position after the ejector spring is flipped and clamped at different positions.

[0058] Furthermore, in this embodiment, the adjustment mechanism 4 includes an adjustment portion 41, which includes a base 411 and a positioning pin 412 protruding from the base 411 and extending upward. The top of the base 411 is formed with an annular end surface 4111, the positioning pin 412 is used for the spring coil to pass through, and the annular end surface 4111 is used to support the ejector pin; the adjustment portion 41 is rotatably arranged around its axis to drive the ejector pin spring to rotate.

[0059] It can be understood that, since the position of the positioning pin 412 is a fixed position, the positions of the positioning pin 412 in the x direction and the y direction are also fixed, and thus, in order to ensure that the spring ring can be accurately sleeved on the positioning pin 412 when the two clamping arms 311 are loosened after the turnover part 31 is turned over, it is also necessary to ensure that the turnover part 31 can preliminarily adjust the position of the spring ring while clamping the spring ring each time.

[0060] It can be understood that, in order to enable the spring ring to be sleeved on the periphery of the positioning pin 412, the positioning pin 412 and the spring ring are arranged in a clearance fit. Since the thimble and the spring ring are eccentrically arranged, when the spring ring is sleeved on the positioning pin 412, the thimble is located on the side of the positioning pin 412, and the thimble spring is supported on the annular end face 4111 through the thimble. In this way, when the adjusting part 41 is rotated, the thimble spring and the annular end face 4111 have a friction force, and thus the thimble spring rotates an angle along with the rotation of the adjusting part 41, so as to adjust the angle of the thimble, so that the thimble can be adjusted to the required clamping angle of the pickup part 51.

[0061] Further, in order to better adjust the thimble to the required angle, in the embodiment, the adjusting mechanism 4 further comprises a stop part 42, which is used to stop the thimble when the adjusting part 41 drives the thimble spring to rotate, so that the thimble spring can be limited in position. Since the positioning pin 412 and the spring ring are arranged in a clearance fit, the spring ring has a degree of freedom of rotation relative to the positioning pin 412 when the spring ring is subjected to an external force in the circumferential direction thereof, and thus, when the adjusting part 41 drives the thimble spring to rotate, the thimble is limited after the thimble abuts against the stop part 42, and then when the adjusting part 41 is further rotated, the thimble spring overcomes the friction force between the thimble spring and the annular end face 4111 and forms relative sliding with the annular end face 4111. In this way, the spring ring only stops the thimble through the stop part 42 when the thimble spring is driven to rotate, and the position of the thimble of the thimble spring is determined according to the position of the stop part 42, without the need for other position detection devices (such as a position sensor) to identify and detect the initial position of the thimble, and without the need for a control device to calculate the displacement amount required for adjustment of the adjusting part 41, so that the structure is simple and the positioning is accurate.

[0062] Furthermore, in this embodiment, the picking portion 51 includes a clamping claw 511 and a stopper 512, the clamping claw 511 includes two clamping arms that can be arranged to move away from and approach each other, each of the clamping arms includes a first clamping arm section 5111 and a second clamping arm section 5112 arranged in sequence from top to bottom, a first clamping space 511a for clamping a spring coil is formed between the two first clamping arm sections 5111, and a second clamping space 511b for clamping an ejector pin is formed between the two second clamping arm sections 5112; the stopper 512 has a limiting portion arranged between the first clamping space 511a and the second clamping space 511b, and the limiting portion is used to abut the upper end of the ejector pin during the movable stroke when the ejector pin is inserted into the socket of the product.

[0063] When the clamping jaws 511 clamp the spring coil, the two first clamping arm sections 5111 clamp the spring coil, and the two second clamping arm sections 5112 clamp the ejector pin. The connection between the ejector pin and the spring coil is located at the lower end of the stopper 512, that is, the upper end of the ejector pin abuts against the stopper 512. Therefore, when inserting the ejector spring, the spring coil has an elastic force, which will cause the ejector pin to move upward when inserted downward. The stopper 512 abuts the upper end of the ejector pin, effectively preventing the spring and rubber from releasing stress and popping out after spring assembly.

[0064] Furthermore, in order to facilitate a more stable clamping effect when the clamping jaw 511 clamps the ejector pin, a concave-convex structure 51121 is provided on the opposite sides of the two second clamping arm sections 5112. The concave-convex structure 51121 can be provided as a V-shaped groove. In this way, by providing a V-shaped groove structure, the friction of the ejector pin is increased and horizontal upward swing is avoided.

[0065] Specifically, in this embodiment, the adjustment station and the assembly station are spaced apart in the longitudinal direction; the assembly mechanism 5 also includes an adjustment component, and the adjustment component includes a first drive device 52, a second drive device 53 and a third drive device 54, the first drive device 52 is installed on the machine base 1, and the first drive device 52 has a first drive part that is movably arranged along the longitudinal direction; the second drive device 53 is fixedly connected to the first drive part, and the second drive device 53 has a second drive part that is movably arranged in the up and down directions; the third drive device 54 is fixedly connected to the second drive part, and the third drive device 54 has an output shaft extending in the up and down directions, and the output shaft is fixedly connected to the picking part 51 to drive the picking part 51 to move. In this way, the first driving device 52 can drive the picking part 51 to move from the adjustment station to the assembly station, so that after picking up the ejector spring from the adjustment part 41, it is transported to the assembly station, and driven by the second driving device 53 to drive the picking part 51 downward, so that it is inserted into the product. Finally, the third driving device 54 can adjust the rotation of the picking part 51 to adjust the assembly angle of the ejector spring.

[0066] Furthermore, in this embodiment, the assembly equipment 100 also includes a first position measuring device and a second position measuring device, and the control device is electrically connected to the first driving device 52, the second driving device 53, the third driving device 54, the first position measuring device and the second position measuring device, and is used to control the operation of the first driving device 52, the second driving device 53 and the third driving device 54 according to the first position measuring device and the second position measuring device.

[0067] In this way, the first position measuring device measures the position of the ejector spring picked up by the pickup portion 51, and the second position measuring device measures the position of the product at the assembly station. The assembly logic uses the ejector as the positioning center and the line connecting the center distance between the ejector and the spring coil as the reference direction to assemble it into the product mainboard hole and insert it into the rubber.

[0068] Specifically, in this embodiment, the first position determination device includes a first visual acquisition system, and / or the second position determination device includes a second visual acquisition system. By using this method of image recognition through photographic capture, the position of the ejector pin and the center of the spring coil can be determined based on the captured contour, thereby facilitating visually guided assembly.

[0069] The present invention also provides an assembly method, which is implemented based on an assembly device 100. The assembly device 100 includes a machine base 1, a material transport mechanism 2, a flip mechanism 3, an adjustment mechanism 4 and an assembly mechanism 5. The machine base 1 is provided with a loading station, a material picking station, an adjustment station and an assembly station; the material transport mechanism 2 includes a picking portion 21 for picking up an ejector spring, and the picking portion 21 is movably arranged and has a movable stroke between the loading station and the picking station, and is used to transport the ejector spring at the loading station to the picking station; the flip mechanism 3 includes a flip portion 31 rotatably mounted on the machine base 1, and the flip The rotating portion 31 is used to flip the ejector spring transported by the material-retrieving portion 21 so that the ejector pin of the ejector spring faces downward; the adjusting mechanism 4 is used to adjust the angle of the ejector spring located at the adjusting station; the assembling mechanism 5 includes a movably arranged picking portion 51, the picking portion 51 having a movable stroke between the material-retrieving station and the assembly station, and being used to pick up the ejector spring on the adjusting portion 41 and bring it to the assembly station. The picking portion 51 also has a downward movable stroke, and is used to insert the ejector pin of the ejector spring into the socket of the product located at the assembly station during the downward movable stroke. The steps of the assembling method include:

[0070] Step S10: The picking portion 21 transports the ejector spring at the loading station to the turning portion 31 at the picking station, and turns the turning portion 31 over so that the ejector pin of the ejector spring faces downward.

[0071] When the material is received, the ejector pin of the ejector spring of the loading station is set upward. In order to make the ejector spring convenient for later assembly, the ejector spring is flipped by providing a flipping portion 31 so that the ejector pin of the ejector spring faces downward, so that the ejector spring is in a preliminary posture to be assembled.

[0072] Step S20: adjusting the angle of the ejector spring transported to the adjustment station by the adjusting mechanism 4 so that the ejector on the ejector spring is at a preset position.

[0073] When the ejector spring is transported to the adjustment station, the position of the ejector pin of the ejector spring cannot be determined. In order to facilitate the subsequent grasping of the picking portion 51 and enable the ejector spring to be adjusted to the desired posture to be grasped, the adjustment mechanism 4 adjusts the ejector spring so that the ejector pin is in the preset position that is convenient for the picking portion 51 to pick up.

[0074] In step S30 , the picking unit 51 picks up the ejector spring at the preset position and transports it to the assembly station, where the downwardly disposed ejector pin is inserted downward into the socket of the product.

[0075] In the technical solution provided by the present invention, the picking portion 21 picks up the ejector spring with its ejector pin facing upward when the material is in the loading station, and transports it to the flipping mechanism 3 of the picking station. The flipping portion 31 flips the transported ejector spring so that the ejector pin of the ejector spring faces downward, and then adjusts the angle of the ejector spring through the adjusting mechanism 4 so that the ejector pin can be adjusted to a suitable position for subsequent assembly. The picking portion 51 picks up the ejector spring with the ejector pin facing downward, and transports it to the assembly station. During the downward movement, the ejector pin of the ejector spring is inserted into the socket of the product in the assembly station, so as to provide an assembly method that can accurately and efficiently realize automatic assembly of the pin spring and the product, and solve the problems of low manual operation efficiency and poor quality in the feeding and assembly process of the pin spring.

[0076] The adjustment mechanism 4 includes an adjustment portion 41, which includes a base 411 and a positioning pin 412 protruding from the base 411 and extending upward. The top of the base 411 is formed with an annular end surface 4111. The positioning pin 412 is used to pass through the spring coil, and the annular end surface 4111 is used to support the ejector pin. The adjustment portion 41 is rotatable about its axis to drive the ejector spring to rotate. The adjustment mechanism 4 also includes a stopper 42. When the adjustment portion 41 drives the ejector spring to rotate, the stopper 42 is used to stop the ejector pin, so that the ejector spring is fixed in a preset position.

[0077] Step S20: The step of adjusting the angle of the ejector spring transported to the adjustment station by the adjustment mechanism 4 so that the ejector pin on the ejector spring is at a preset position includes:

[0078] Step S201 : Sleeve the ejector spring with the ejector pin facing downward onto the positioning pin 412 , so that the ejector spring is supported on the base 411 through the ejector pin.

[0079] In order to enable the spring ring to be sleeved on the circumferential side of the positioning pin 412, the positioning pin 412 and the spring ring are set to be clearance fit. Since the ejector pin and the spring ring are eccentrically arranged, when the spring ring is sleeved on the positioning pin 412, the ejector pin is located beside the positioning pin 412, and the ejector pin spring is supported on the annular end surface 4111 through the ejector pin.

[0080] In step S202 , the adjusting portion 41 drives the ejector spring to rotate. During the rotation of the ejector spring, the ejector contacts the stop portion 42 .

[0081] In the technical solution provided by the present invention, when the adjusting portion 41 drives the ejector spring to rotate, the ejector pin abuts against the stop portion 42, limiting its position. Subsequently, as the adjusting portion 41 rotates further, the ejector pin spring overcomes the friction between the spring and the annular end surface 4111, sliding relative to the annular end surface 4111. In this manner, the spring coil merely stops the ejector pin via the stop portion 42 when the ejector spring is driven to rotate. The position of the ejector pin of the ejector spring is determined by the position of the stop portion 42, eliminating the need for a separate position detection device to identify the ejector pin's initial position, or a control device to calculate the required displacement of the adjusting portion 41. This results in a simple structure and precise positioning.

[0082] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
