DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] like Figure 1 to Figure 7As shown, the present invention discloses a needle insertion device, which includes a needle insertion assembly 5, which includes: a shell, a first cavity arranged along the axial direction of the shell, a first inlet connected to the first cavity, a second inlet 9 and an outlet are arranged on the shell, the first inlet is located at the first end of the cavity, the second inlet 9 is used for inserting the needle, the second inlet 9 and the first inlet are inclined and arranged toward the second end of the first cavity, the outlet is located at the second end of the cavity and is coaxially arranged with the jack; a pushing unit, the pushing unit can enter the first cavity from the first inlet and move toward the outlet; a discharging unit; a guide channel, the guide channel is located between the outlet and the jack, the inner diameter of the guide channel is larger than the diameter of the needle, and the guide channel It is coaxially arranged with the socket; wherein, when the pin assembly 5 is in the needle insertion state, the diameter of the outlet is larger than the diameter of the second end of the needle and smaller than the diameter of the positioning portion, the positioning portion is located in the area of ​​the needle away from the second end of the needle, and the diameter of the positioning portion is the maximum diameter of the needle; when the pin assembly 5 is in the pin insertion state, under the first force, the second end of the needle extends out of the outlet and enters the socket through the guide channel, and then the discharge unit makes the diameter of the outlet larger than the diameter of the needle, and at the same time, under the second force, the pushing unit enters the first cavity from the first entrance and pushes the needle toward the socket until the second end of the needle enters the socket; the first end of the needle is the end of the needle close to the first entrance, and the second end of the needle is the end of the needle away from the first entrance.

[0044] When the pin assembly 5 is in the needle insertion state, the diameter of the outlet is larger than the diameter of the second end of the needle and smaller than the diameter of the positioning part. The positioning part is located in the area of ​​the needle away from the second end of the needle, and the diameter of the positioning part is the maximum diameter of the needle. This makes the needle not fully extend from the shell before the posture is adjusted, that is, before the needle is aligned with the socket. The needle insertion operation will not be performed, which reduces the problem of the needle not being inserted into the socket due to the needle not being aligned with the socket; when the pin assembly 5 is in the needle insertion state, the first force makes the second end of the needle extend out of the outlet and enter the socket through the guide channel. Subsequently, the discharge unit makes the diameter of the outlet larger than the diameter of the second end of the needle. At the same time, under the second force, the pushing unit enters the cavity from the first entrance and moves toward the outlet to push the needle until the needle is inserted into the socket. Because the guide channel and the socket are coaxially arranged, the needle can accurately enter the socket when it moves toward the socket, thereby improving the accuracy of the needle insertion, thereby reducing the problem of the need to pull out the needle for secondary insertion due to the inability to accurately insert the needle into the socket, thereby improving the efficiency of the needle insertion.

[0045] The pin insertion device of the present invention can be used for inserting pins of various types of pins, for example, the pin can be inserted into different types of workpieces to be inserted such as a pin tube, a pin plate, a pin loading plate, or a terminal. The pusher unit can specifically include a pin 15, and a third drive device 12 connected to the pin 15 in a transmission manner. The end of the pin 15 facing the pin is larger than the diameter of the pin, so that the pin 15 pushes the pin to move toward the insertion hole. The third drive device 12 can specifically be a linear drive device such as a cylinder. The third drive device 12 and the pin 15 are both arranged along the axial direction of the shell, so that when the pin assembly 5 is in the pin insertion state, the third drive device 12 drives the pin 15 to push the pin; the second force is the force applied by the drive device to the pin 15; the pin 15 can be always located in the shell, or when the pin assembly 5 is in the pin insertion state, it can enter the shell from the first entrance to push the pin, depending on the working conditions. The positioning part can specifically be arranged at the first end of the pin, or in the area between the two ends of the pin. The diameter of the needle refers to the largest diameter on the pointer. The positioning part can specifically be a ring structure on the needle.

[0046] Furthermore, in the present invention, the intersection of the first cavity and the outlet is inclined relative to the axial direction of the shell, and the inclination angle of the intersection is greater than the repose angle of the needle. Then, when the needle enters the first cavity from the second inlet 9 and abuts against the shell, because the inclination angle of the intersection is greater than the repose angle of the needle, the force of the needle moving toward the outlet is greater than the friction force of the needle at the intersection, which causes the needle to move toward the outlet until the second end of the needle extends out of the shell. At this time, the first force is the gravity component of the needle at the intersection along the inclination direction of the intersection; or, when the outlet is located on the extension line of the second inlet, that is, the second inlet is aligned with the outlet, the needle can directly enter the outlet after entering the second cavity from the second inlet, and the second end of the needle can extend from the outlet. At this time, the first force is the gravity of the needle and the force of the air transporting the needle; and / or, the positioning portion and the socket are transitionally matched, and through the transitional match between the positioning portion and the socket, the needle will not be significantly skewed during the process of being inserted into the socket, and the needle can be inserted in a direction close to the coaxial direction of the socket; or, an opening with a trapezoidal longitudinal cross-section can be provided on the side of the socket close to the outlet, and the inclination angle of the opening is greater than the repose angle of the needle, so that even if the needle abuts at the opening, it can continue to move downward along the opening until the needle and the socket are coaxially arranged; and / or, the intersection of the extension line of the second inlet 9 and the shell is located outside the extension line of the outlet, so that after the needle enters the first cavity, the needle will temporarily abut against the first cavity, preventing the second inlet 9 from being aligned with the outlet, resulting in the needle not adjusting its posture and extending from the shell in a direction inclined relative to the axial direction of the shell, thereby reducing the quality of the needle.

[0047] The shell and the discharge unit in the present invention have various settings. The shell includes a substrate, a first shell 13 and a second shell 14 surrounding the first cavity, and the first shell 13, the second shell 14 and the substrate are rotatably connected in the plane where the line connecting the outlet and the jack is located; when the pin assembly 5 is in the needle insertion state, the second end of the first shell 13 abuts against the second end of the second shell 14; when the pin assembly 5 is in the pin insertion state, the pusher unit abuts against the shell in the process of moving toward the jack, and the gap between the second end of the first shell 13 and the second end of the second shell 14 is greater than the diameter of the positioning portion; the discharge unit includes a pusher unit, a first shell 13 and a second shell 14; the second end of the first shell 13 is the end of the first shell 13 close to the outlet, and the second end of the second shell 14 is the end of the second shell 14 close to the outlet. Because the diameter of the pushing unit is larger than the diameter of the outlet, the second end of the first shell 13 abuts against the second end of the first shell 13, and the pushing unit abuts against the shell during the process of moving toward the insertion hole. As a result, during the process of moving toward the insertion hole, the pushing unit causes the first shell 13 and the second shell 14 to rotate away from each other, thereby increasing the gap between the first shell 13 and the second shell 14, that is, the diameter of the outlet, so that the outlet diameter is larger than the diameter of the positioning portion, so that the pushing unit opens the outlet at the same time when pushing the needle toward the insertion hole, so that the needle can successfully complete the insertion operation.

[0048] The present invention provides a first positioning member 21 and a second positioning member 22 at the first end of the first housing 13 and the first end of the second housing 14, respectively. The first positioning member 21 applies a third force to the first housing 13, and the second positioning member 22 applies a fourth force to the second housing 14. The third force and the fourth force cause the second end of the first housing 13 and the second end of the second housing 14 to abut against each other. The first positioning member 21 and the second positioning member 22 may be torsion springs, which can keep the second end of the first housing 13 and the second end of the second housing 14 abutting against each other when the pin assembly 5 is in the inserted state.

[0049] Alternatively, when the first end of the shell and the second end of the shell are arranged in sequence from top to bottom, and the diameter of the outlet is smaller than the diameter of the positioning portion, the first positioning member 21 and the second positioning member 22 can be omitted, and the first shell 13 and the second shell 14 can be kept in contact by gravity.

[0050] The guide channel has various configurations. Figure 1 to Figure 3As shown, the pin assembly 5 includes a clamping member, the clamping direction of the clamping member is perpendicular to the axial direction of the shell, and the clamping member is provided with a clamping portion. When the second end of the needle extends from the outlet, the clamping member clamps the second end of the needle, and the clamping portion forms a guide channel; the clamping member includes a pair of jaws 10, which are transmission-connected to the jaws 10 and can realize a first driving device 8 that clamps or releases the needle. The first driving device 8 can specifically be a cylinder. The clamping member can also include a connecting rod structure arranged between the first driving device 8 and the jaws 10. When the second end of the needle extends from the outlet, the clamping member clamps the second end of the needle to prevent the needle from being skewed significantly during the process of entering the socket, thereby ensuring the accuracy of the pin insertion. Alternatively, the pin assembly 5 includes a guide track with a guide channel therein. The guide track is a section of track arranged along the axial direction of the shell, and both ends of the guide track have openings.

[0051] The pin insertion device of the present invention further includes a cooperation component 3, which is used to drive the pin insertion component 5 or the workpiece to be inserted so that the guide channels are aligned with the insertion holes on the workpiece to be inserted one by one. The cooperation component 3 can be a robot with multiple degrees of freedom, also known as a robot arm. When the cooperation component 3 is connected to the pin insertion component 5, the pin insertion component 5 is located at the end of the robot, and the number of degrees of freedom of the robot needs to enable the robot to drive the pin insertion component 5 to move and rotate in the three-dimensional direction of space.

[0052] like Figure 5 , Figure 6 As shown, the needle insertion device also includes a dividing component 4, which includes a dividing piece 16, a vibrating piece 17 and a plurality of discharge channels. The dividing piece 16 is connected to the second inlet 9 through the discharge channel. The dividing piece 16 has a third inlet for adding needles. The dividing piece 16 has a second cavity for accommodating needles, and the size of the discharge channel matches the size of the needles in a set direction. When the dividing component 4 is in a dividing state, the vibrating piece 17 applies a fifth force to the dividing piece 16, and the fifth force separates the needles.

[0053] The material distribution member 16 can be specifically a material distribution barrel, and the vibration member 17 can be specifically a vibration source that can drive the material distribution member 16 to twist with its own axis. A spiral channel can also be provided on the material distribution barrel, or multiple steps can be provided from bottom to top to facilitate the discharge of the needle. The size of the discharge channel is consistent with the size of the needle in a set direction, which means that if the needle is required to move along the discharge channel in a certain direction, the size of the discharge channel is set to the size of the needle in that direction. For example, if the needle is required to enter the discharge channel in a vertical state, the width of the discharge channel is made slightly larger than the diameter of the needle and smaller than the length of the needle. In this way, the needle in the horizontal state will be rejected because it cannot enter the discharge channel.

[0054] Furthermore, the discharge channel of the present invention includes a first channel 18 connected to the top of the material dividing member 16, a second channel 19 connected to the second inlet 9, and a material moving member 20 disposed between the first channel 18 and the second channel 19. The material moving member 20 may be a material moving plate, and the material moving member 20 is used to transfer the needle from the needle in the first channel 18 to the second channel 19. The material moving member 20 has a material moving portion that can only carry one needle, and the material moving portion allows one needle to enter the shell at a time, thereby avoiding the problem that multiple needles enter the shell at the same time, causing the two needles to interfere with each other and it is difficult to extend from the shell for inserting the needle; or, the end of the discharge channel close to the material dividing member 16 is higher than the end of the discharge channel close to the second inlet 9, and at this time, the needle can be transferred by relying on the gravity of the needle itself. The second channel 19 may be a material pipe, and one end of the material pipe is connected to the second inlet 9 through a through hole provided on the hanging plate 7 of the cover shell 6. The movement of the needle in the discharge channel can be transported by air.

[0055] like Figure 6 As shown, the material moving part includes a material moving plate, and a first through hole is provided on the side of the material moving plate facing the first channel 18. The first through hole can be in an arc shape, and the hole can only accommodate one needle. The material moving plate is located above the second channel 19, and the material moving plate is connected to a driving structure. The material moving plate is driven by the driving structure to move, so that the first through hole and the second channel 19 are intermittently connected. Specifically, the driving structure first drives the material moving plate toward the side close to the first channel 18 to receive the needle delivered by the first channel 18, and then the driving structure drives the material moving plate to move toward the second channel 19. After the first through hole and the second channel 19 are aligned, the needle enters the second channel 19; a first baffle is provided below the material moving plate, and a second baffle is provided on the side close to the first channel, and a first baffle is provided on the first baffle The second through hole connected to the two channels, the first through hole and the second through hole are not in the same straight line, the first baffle and the second baffle can prevent the needle in the first through hole from falling, so that the needle received by the material moving plate falls into the second channel after the first through hole is aligned with the second through hole; the driving structure includes a first driving structure that drives the material moving plate to move toward and away from the first channel to adapt to different types of needles, the first driving structure can be specifically a linear driving device such as a cylinder, and a second driving structure that drives the material moving plate to move in a direction perpendicular to the extension direction of the first channel, the material moving plate is driven to move by the second driving structure to achieve intermittent connection between the first through hole and the second through hole, the second driving structure can be specifically a linear driving device such as an electric push rod.

[0056] The pin insertion device further includes a positioning assembly 2, which includes a plurality of positioning members arranged in multiple directions of the workpiece to be inserted, and the positioning members are in contact with the workpiece to be inserted, and the plurality of positioning members can prevent the workpiece to be inserted from being offset during the insertion process, thereby further improving the pin insertion accuracy; the positioning member can be a positioning plate or a positioning groove; Figure 7As shown, the positioning assembly 2 includes a first positioning member 21, which is opposite to the feeding direction, a third positioning member 23 connected to the first positioning member 21 and located on the side of the first positioning member 21, and a second positioning member 22 is arranged on a two-dimensional guide rail. The corresponding driving assembly 25 can drive the second positioning member 22 to move toward and away from the first positioning member 21 and the third positioning member, so that the positioning assembly 2 can realize the positioning and clamping of different types of workpieces with holes. The positioning assembly 2 also includes a fourth positioning member 24, which is located below the first positioning member 21 and is used to carry the workpiece to be inserted. The first positioning member 21, the second positioning member 22, the third positioning member 23 and the fourth positioning member 24 can be specifically positioning plates. The workpiece to be inserted can be specifically a structure that needs to be inserted such as a hanging pin board. The pin insertion device also includes a frame 1 assembly, which has a third cavity, and the third cavity includes a connected working area and a feeding area. The working area is provided with a pin insertion assembly 5 and a material dividing assembly 4, and the positioning assembly 2 can move between the working area and the feeding area. The loading area is set close to the staff, and the problem of operators being accidentally injured by the equipment when loading is avoided by separating the working area and the loading area. The operator fixes the workpiece to be inserted with the positioning component 2 in the loading area. After fixing the workpiece to be inserted with the pin, the positioning component 2 is moved to the working area through the driving component 25, so that the subsequent pin insertion component 5 can insert the workpiece to be inserted with the pin. The driving component 25 can be a linear driving device such as a cylinder.

[0057] In addition, the pin insertion device of the present invention further includes a controller, which is connected to the cooperation component 3, the pin insertion component 5, and the material distribution component 4 by signal. The controller stores relevant motion programs, which enables the cooperation component 3 to drive the pin insertion component 5 to move along a set trajectory, so that the socket can be accurately aligned with the outlet, further improving the pin insertion accuracy. The pusher unit also includes a travel switch provided on the output shaft of the drive device, and the travel switch is used to determine whether the ejector pin 15 pushes the needle downward by a set distance. The pin insertion device also includes a second drive device 11 that can drive the pin insertion component 5 to move toward and away from the socket. The second drive device 11 can specifically be a linear drive device such as a cylinder.

[0058] In addition, the discharge unit may not adopt the above-mentioned form. For example, the discharge unit includes a discharge ring arranged at the outlet, the discharge ring is rotatably connected to the shell, and a first discharge hole with a diameter smaller than the diameter of the second end of the needle and a second discharge hole with a diameter not smaller than the diameter of the second end of the needle are provided on the discharge ring. The diameter of the outlet is larger than the diameter of the first end of the needle; when the needle assembly 5 is in the needle insertion state, the first discharge hole and the outlet are connected, and when the needle assembly 5 is in the needle insertion state, the second discharge hole and the outlet are connected; a driving structure rotatably connected to the discharge ring may be provided, and the discharge ring is driven to rotate by the driving structure to realize the alignment of the outlet with the first discharge hole or the second discharge hole, thereby realizing the adjustment of the diameter at the outlet.

[0059] The "and / or" in this article refers to the same sentence. The text content before and / or and the text content after and / or can exist at the same time or separately. For example, A and / or B includes the three situations of only A or B and A and B existing at the same time.

[0060] The present invention discloses multiple technical solutions, but does not provide any contrary technical inspiration.
