Description

Technical Field

[0001] The present application relates to the field of electrical connector production equipment, and in particular to cam terminal plugging equipment. Background Art

[0002] An electrical connector is a device that bridges two conductors in a loop so that current or signals can flow from one conductor to another. This connection may be temporary and easy to plug and unplug at any time, or it may be a permanent junction between electrical devices or wires. In the electronics industry, connectors are widely used, and with the development of related technologies, the size of connectors is getting smaller and smaller. Connectors are mainly composed of a housing and terminals (pins). During the production process, the terminals need to be inserted into the housing, and the number of terminals on the housing varies depending on the number of pins.

[0003] In the Chinese patent document with the announcement number CN217009870U, an automatic terminal inserting machine is disclosed, and specifically discloses a skeleton conveying mechanism, a skeleton pushing mechanism, a skeleton shifting mechanism, an end piece sending mechanism, and an inserting mechanism. The skeleton conveying mechanism conveys the skeleton, the skeleton pushing mechanism pushes the skeleton at the end of the skeleton conveying mechanism onto the skeleton shifting mechanism, the skeleton shifting mechanism transfers the skeleton to the opposite side of the inserting mechanism, the end piece sending mechanism sends the end piece to the front side of the inserting mechanism, and the inserting mechanism inserts the end piece into the skeleton. The patent realizes the automatic insertion of the terminal through the sequential actions of multiple mechanisms.

[0004] However, in the above patent, the insertion of the terminal requires the joint action of multiple cylinders, the overall efficiency is low, and the probability of failure is greatly increased. Summary of the invention

[0005] In order to improve the problem of low efficiency in plugging the terminal into the housing, the present application provides a cam terminal plugging device.

[0006] The present application provides a cam terminal plugging device, which adopts the following technical solution: The cam terminal plug-in device includes a feeding mechanism and a pushing mechanism. The feeding mechanism is used to convey the shell to the pushing mechanism horizontally. The pushing mechanism is arranged on a machine platform. The pushing mechanism includes a feeding wheel, a pressing knife and a cam shaft. The machine platform is also provided with a guide groove. The terminal material strip is adaptively arranged in the guide groove. The feeding wheel extends into the guide groove and is used to push the terminal material strip to move in a vertical direction. The cam shaft is used to drive the pressing knife to reciprocate in a horizontal direction. The moving direction of the pressing knife is perpendicular to the moving direction of the shell.

[0007] By adopting the above technical scheme, under the drive of the feeding wheel, the terminal strip can continuously move downward and approach the pressing knife, and the shell can continuously move horizontally and approach the pressing knife under the drive of the feeding mechanism. In this way, when a shell and a terminal on the terminal strip overlap on the outside of the pressing knife, the camshaft drives the pressing knife to move toward the terminal and press the terminal into the shell, and then the camshaft drives the pressing knife to reset, the feeding wheel drives the terminal strip to move downward one unit, and the feeding mechanism drives the other shell to move toward the pressing knife, and then the terminal is plugged into the other shell. By repeating the above operations, the terminal can be quickly plugged in, which effectively improves the plug-in efficiency.

[0008] Optionally, the camshaft and the feeding wheel are both driven by a motor, the terminal strip is wound on a winding drum, and the winding drum can rotate around its own axis.

[0009] By adopting the above technical solution, when the feeding wheel drives the terminal material strip to move in the feed trough, the terminal material strip can pull the winding drum to rotate, so that the terminal material strip can continuously move toward the pushing mechanism, ensuring a continuous and stable supply of terminals.

[0010] Optionally, the loading mechanism includes a discharge unit and a feeding unit, the discharge unit includes a vibration plate and a material guide trough, the feeding unit includes a feeding block and a base, the base is located on the outside of the machine, and a slider driven by a first screw motor is provided on the base, and the slider drives the feeding block to reciprocate between the material guide trough and the pressing knife.

[0011] By adopting the above technical solution, the vibration plate arranges the shells in sequence and transports them to the material guide trough, and enables the shells to move continuously in the material guide trough. When the shells are transported from the material guide trough to the feed block, the first screw drives the feed block to move, so that the shells on the feed block can move to the outside of the press.

[0012] Optionally, one end of the material guide trough is connected to the discharge port of the vibration plate, and the other end of the material guide trough is provided with a first push rod and a first cylinder, the first cylinder is used to push the first push rod to move toward the feeding block, and a plurality of limit columns are provided at intervals on the feeding block, and the distance between two adjacent limit columns is equal to the length of the shell.

[0013] By adopting the above technical solution, the material guide trough and the feeding block are staggered, so that when the first cylinder is actuated, the first push rod can reliably push the shell onto the feeding block. Under the limiting action of a number of limiting columns, it is ensured that the shell can be arranged at intervals on the feeding block and cannot move in the horizontal direction.

[0014] Optionally, a plurality of the limiting columns form a plurality of placement areas on the feeding block, the first push rod is used to push the shell into the placement area, and the base is provided with a sliding groove for the feeding block and the sliding block to slide.

[0015] By adopting the above technical solution, the setting of the slide groove ensures that the feed block can slide reliably in the length direction of the base. At the same time, a number of placement areas are set on the feed block to improve the arrangement accuracy of the shell on the feed block, thereby ensuring that the terminal can be inserted into the shell more accurately.

[0016] Optionally, a push block is provided at the bottom of the first push rod, and a notch is provided on the side of the material guide trough close to the feeding block, the notch is connected to the material guide trough, the bottom of the notch is flush with the top of the feeding block, and the push block slides in the notch and pushes the shell; a baffle is provided on the top of the feeding block, the baffle extends along the length direction of the feeding block, and the baffle is located on the side of the feeding block away from the material guide trough.

[0017] By adopting the above technical solution, when it is necessary to feed material to the feed block, the first cylinder is actuated to cause the first push rod to extend toward the feed block. During this process, the push rod will come into contact with the shell, thereby pushing the shell to slide outward from the notch and into the placement area. At the same time, under the limiting action of the baffle, it is ensured that the shell will not be pushed away from the top of the feed block.

[0018] Optionally, an opening is provided on the side of the base facing the pressing knife, the opening is connected to the slide slot, a material receiving block is provided in the opening, a second cylinder is also provided in the slide slot, a connecting plate is provided at the end of the second cylinder, a plurality of second push rods are provided on the connecting plate, the second push rods are used to push the shell to move into the material receiving block, and the material receiving block moves toward the pressing knife under the drive of the second screw motor.

[0019] By adopting the above technical solution, when the feeding block is full of shells, the first screw motor drives the feeding block to move toward the receiving block. When the feeding block is flush with the receiving block, the second cylinder is actuated, so that the connecting plate drives the second cylinder to move toward the feeding block and push the shells on the feeding block to the receiving block, thereby realizing the transfer of the shells.

[0020] Optionally, a support plate is provided between the feed block and the slider, the top of the support plate is provided with a groove, and the feed block is adaptively arranged in the groove; a plurality of first springs are provided between the bottom of the groove and the bottom of the feed block, and a third cylinder is fixed to the bottom of the support plate through a bracket, and the third cylinder is used to drive the feed block to move along the depth direction of the groove.

[0021] By adopting the above technical solution, when the third cylinder moves downward, the feeding block will move downward, so that there will be no interference between the limiting column on the top of the feeding block and the second push rod in the horizontal direction. Therefore, when the second push rod is not recovered, the feeding block is recovered, which is convenient for rapid refilling of the shell.

[0022] Optionally, the radial cross-section of the material receiving block is L-shaped, the vertical end of the material receiving block is close to the feeding block, and a plurality of receiving grooves are provided at the top of the horizontal end of the material receiving block. The plurality of receiving grooves are arranged at intervals along the length direction of the material receiving block, and a second spring and a baffle rod are provided in the receiving groove, one end of the second spring is connected to the side wall of the receiving groove, and the other end of the spring is connected to the baffle rod, the receiving groove extends along the width direction of the material receiving block, and the baffle rod slides adaptively in the receiving groove.

[0023] By adopting the above technical solution, when the second push rod pushes the shell to move onto the connecting block, the pushing action of the second push rod on the connecting block will cause the baffle rod to slide in the accommodating groove, thereby expanding the distance between the baffle rod and the vertical end of the connecting block. In this way, when the second push rod is withdrawn, the baffle rod is reset under the action of the second spring, and the shell is reliably clamped between the baffle rod and the vertical end of the connecting block, thereby fixing the shell and preventing the shell from moving during the terminal plugging process and affecting the plugging accuracy.

[0024] Optionally, the distance between two adjacent baffle rods is smaller than the length of the shell, the top height of the baffle rod is larger than the top height of the vertical end of the receiving block, the top of the vertical end of the receiving block is flush with the top of the feeding block, the minimum distance between the baffle rod and the vertical end of the receiving block is smaller than the thickness of the shell, and the second push rod is provided with a slope on the side facing the receiving block, and the slope is in conflict with the shell.

[0025] By adopting the above technical solution, the slope on the second push rod contacts the shell, so that the second push rod can generate a vertical thrust on the shell when pushing the shell to move horizontally and push the baffle rod, thereby ensuring that the shell can fall into the gap between the baffle rod and the vertical end of the material receiving block, and then ensuring that when the second spring pushes the baffle rod to reset, the clamping effect on the shell can be reliably achieved.

[0026] In summary, this application has the following beneficial effects: 1. Under the synchronous action of the feeding mechanism and the feeding wheel, the terminal and the housing are gathered on the outside of the pressing knife, and then the pressing knife is driven by the camshaft to realize the rapid plugging of the terminal on the housing. The action connection is smooth, which effectively improves the plugging efficiency of the terminal.

[0027] 2. The shell moves from the guide trough to the feeding block to realize the spacing and orderly arrangement of the shell. The shell moves from the feeding block to the receiving block to realize the closeness of the shell to the pressing knife and the shell is in a fixed state during the plugging, thereby effectively improving the plugging accuracy.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-6 This application is described in further detail.

[0030] The cam terminal plug-in device includes a feeding mechanism 1 and a pushing mechanism 2. The pushing mechanism 2 is arranged on a machine table 4. The pushing mechanism 2 includes a feeding wheel 21, a pressing knife 22 and a cam shaft 23. A material guide groove 24 and a winding disk 6 are also provided on the machine table 4. The winding disk 6 can rotate around its own axis. A terminal material strip 5 is wound on the winding disk 6. The terminal material strip 5 is formed by connecting a plurality of terminals in sequence and is similar to a chain. The terminal material strip 5 is led out from the winding disk 6 and inserted into the material guide groove 24. The material guide groove 24 extends in a vertical direction. The outer edge of the feeding wheel 21 is inserted into the groove body of the material guide groove 24 and is in a meshing state with the terminal material strip 5. In this way, after the feeding wheel 21 is driven by the motor to rotate, the terminal material strip 5 can move downward and be fed to the outer side of the pressing knife 22. The loading mechanism 1 includes a discharge unit 11 and a feeding unit 12. The discharge unit 11 includes a vibration plate 111 and a guide trough 112. A plurality of shells 3 are poured into the vibration plate 111. Under the vibration of the vibration plate 111, the plurality of shells 3 can be sequentially input into the guide trough 112. With the continuous input of the shells 3, the plurality of shells 3 can be closely arranged and moved horizontally in the guide trough 112 to the outside of the feeding unit 12. The feeding unit 12 includes a feeding block 121 and a base 122. The base 122 is located on the outside of the machine table 4. The feeding block 121 slides along the length direction of the base 122 under the drive of the first screw motor 13. The feeding block 121 is located at one end of the guide trough 112 away from the vibration plate 111. A first push rod 113 pushed by a first cylinder 114 is provided at the connection between the guide trough 112 and the feeding block 121. The first push rod 113 pushes the shell 3 in the guide trough 112 onto the feeding block 121 in sequence under the drive of the first cylinder 114.

[0031] A push block 1130 is provided at the bottom of the first push rod 113, and a notch 1120 is provided at one end of the guide trough 112 away from the vibration disk 111. The bottom of the notch 1120 is flush with the top of the feed block 121. The push block 1130 slides in the notch 1120 and pushes the housing 3; the first cylinder 114 pushes the first push rod 113 to slide in the notch 1120. The end of the guide trough 112 away from the vibration disk 111 and the end of the feed block 121 close to the vibration disk 111 are staggered and fit each other. A plurality of limit posts 1211 are provided at the top of the feed block 121. The plurality of limit posts 1211 are spaced apart along the length direction of the feed block 121, and the spacing length is equal to or slightly greater than the length of the housing 3. A slide groove 1221 is provided on the side of the base 122 facing the machine 4, the first screw motor 13 is arranged in the slide groove 1221, and a slider 130 is adaptively rotated on the screw on the first screw motor 13, a supporting plate 127 is provided on the side of the slider 130 facing the machine 4, and the feeding block 121 is arranged on the supporting plate 127. A placement area 1212 is formed between two adjacent limit columns 1211. After the first cylinder 114 is actuated, the push block 1130 on the first push rod 113 pushes a shell 3 into a placement area 1212, and then the first screw motor 13 drives the feeding block 121 to move a distance of the length of a shell 3, so that another placement area 1212 is aligned with the notch 1120. At the same time, the push block 1130 is reset, and the next shell 3 is pushed into the notch 1120, and then the push block 1130 is pushed out again to push the shell 3 into the new placement area 1212. In this way, through multiple movements of the feeding block 121 and repeated pushing of the push block 1130, each placement area 1212 can be filled with a shell 3. Furthermore, a baffle 1213 is provided on the top of the feed block 121, and the baffle 1213 extends along the length direction of the feed block 121. The baffle 1213 is located on the outer side of the limiting column 1211 and away from the push block 1130. In this way, when the push block 1130 pushes the shell 3 into the placement area 1212, the baffle 1213 can limit and shield the shell 3 to prevent the shell 3 from moving out of the placement area 1212.

[0032] When the placement area 1212 on the feeding block 121 is filled with the housing 3, the first screw motor 13 is activated to move the feeding block 121 toward the pressing knife 22. An opening 1222 is also provided on the side of the base 122 facing the machine table 4, the opening 1222 is connected to the slide slot 1221, and a receiving block 123 is provided in the opening 1222. The receiving block 123 moves along the length direction of the base 122 under the drive of the second screw motor 14. The radial cross-section of the material receiving block 123 is L-shaped, and the vertical end of the material receiving block 123 is close to the feeding block 121. The horizontal end of the material receiving block 123 is provided with a plurality of accommodating grooves 1231, and the accommodating grooves 1231 extend along the width direction of the material receiving block 123. The plurality of accommodating grooves 1231 are arranged at intervals along the length direction of the material receiving block 123. A second spring 1232 and a baffle rod 1233 are provided in the accommodating groove 1231, and one end of the second spring 1232 is connected to the inner wall of the accommodating groove 1231, and the other end of the second spring 1232 is connected to the outer wall of the baffle rod 1233. The baffle rod 1233 is located between the second spring 1232 and the vertical end of the material receiving block 123, and the distance between two adjacent baffle rods 1233 is less than the length of the shell 3.

[0033] A second cylinder 124 and a connecting plate 125 are also provided in the slide groove 1221. The connecting plate 125 extends along the length direction of the feeding block 121. The connecting plate 125 is located on the side of the feeding block 121 away from the receiving block 123. A plurality of second push rods 126 are provided on the side of the connecting plate 125 facing the receiving block 123. When the second cylinder 124 drives the connecting plate 125 to move toward the feeding block 121, the plurality of second push rods 126 will push all the housings 3 with the feeding block 121 onto the receiving block 123. A slope 1260 is provided at one end of the second push rod 126 facing the receiving block 123. When the second push rod 126 contacts the shell 3, an extrusion effect is generated between the slope 1260 and the shell 3. In this way, the shell 3 will have a downward movement tendency during the process of horizontal movement from the feeding block 121 to the receiving block 123, so that the shell 3 can reliably move between the blocking rod 1233 and the vertical end of the receiving block 123, and contact the top of the horizontal end of the receiving block 123. Furthermore, in the process of the shell 3 moving to the receiving block 123, since the distance between the baffle rod 1233 and the vertical end of the receiving block 123 is smaller than the width of the shell 3, the shell 3 will push the baffle rod 1233 to move in the accommodating groove 1231 and compress the second spring 1232. When the shell 3 is completely displaced, the second push rod 126 is withdrawn, and the baffle rod 1233 is reset and presses the shell 3 under the push of the second spring 1232, thereby reliably fixing the shell 3 between the baffle rod 1233 and the vertical end of the receiving block 123.

[0034] A groove 1271 is provided at the top of the supporting plate 127, and the feed block 121 is arranged in the groove 1271. A plurality of first springs 1272 are provided between the bottom of the groove 1271 and the bottom of the feed block 121. When the first spring 1272 is only subjected to the downward pressure of the feed block 121, the first spring 1272 can support the feed block 121 and ensure that the limiting column 1211 is located above the groove 1271. A third cylinder 1274 is provided at the bottom of the supporting plate 127, and the third cylinder 1274 is fixed to the supporting plate 127 by a bracket 1273. The third cylinder 1274 is used to push and pull the feed block 121 in the vertical direction. When the third cylinder 1274 pulls the feed block 121 downward, the feed block 121 and the limiting column 1211 completely enter the groove 1271. At this time, there is no interference between the limiting column 1211 and the second push rod 126. In this way, when the second push rod 126 pushes the shell 3 to leave the feed block 121, the third cylinder 1274 can pull the feed block 121 downward, so that the feed block 121 can be recovered and the shell 3 can be filled again, and the second push rod 126 can still further push the shell 3, thereby improving the overall continuity.

[0035] When the shell 3 is securely clamped on the connecting block 123, the second screw motor 14 drives the connecting block 123 to move toward the outside of the pressing knife 22. In this way, the shell 3 and the terminal strip 5 are both moved to the outside of the pressing knife 22. At this time, the camshaft 23 can be driven to rotate by another motor to realize the reciprocating drive of the pressing knife 22. The moving direction of the pressing knife 22 is perpendicular to the moving direction of the shell 3 and the terminal strip 5, and the moving direction of the shell 3 is also perpendicular to the moving direction of the terminal strip 5, so that the terminals on the terminal strip 5 are pressed into the shell 3. Through the micro-drive of the connecting block 123 by the second screw motor 14, multiple terminals can be plugged into a shell 3 according to design requirements. When the specified number of terminals are plugged into all terminals, the second screw motor 14 drives the connecting block 123 away from the pressing knife 22 and enters the detection mechanism, and the terminal plug-in operation is completed.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
