DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0020] Embodiment 1: An assembly device for connector production, such as Figure 1-Figure 8 As shown, it includes a base frame 1, a socket frame 2, a pin frame 3, a cylinder 6, a mounting plate 7 and a push rod 8; the base frame 1 is connected to the socket frame 2; the socket frame 2 is provided with a socket slot 201; the base frame 1 is bolted with the pin frame 3; the pin frame 3 is provided with a plurality of pin slots 301; two cylinders 6 are fixedly connected to the base frame 1; the telescopic ends of all cylinders 6 are fixedly connected to a mounting plate 7; a plurality of push rods 8 are fixedly connected to the mounting plate 7 at equal intervals; each push rod 8 is respectively matched with a pin slot 301; It also includes a mounting frame 4 and a needle frame 5; the mounting frame 4 is welded on the base frame 1; the needle frame 5 is slidably connected to the mounting frame 4; a feed groove 501 is provided at the lower part of the needle frame 5, and the feed groove 501 can only allow one pin to pass through; the lower side of the needle frame 5 is in contact with the upper side of the socket frame 2.

[0021] In order to facilitate the insertion of the needle to slide down into the feed groove 501, the inner bottom side of the needle frame 5 is V-shaped.

[0022] In order to facilitate the bottom of the needle frame 5 to slide on the socket frame 2, the lower end of the needle frame 5 is configured to be arc-shaped.

[0023] In order to facilitate the insertion of the needle to slide down into the needle groove 301, the upper end of the needle groove 301 is provided with an oblique angle.

[0024] It also includes a push plate 21, a pressing plate 22 and a spring telescopic rod 23; the push plate 21 is slidably connected to the needle frame 5; the lower side of the push plate 21 contacts the inner bottom side of the needle frame 5; the push plate 22 is fixedly connected to the push plate 21; two spring telescopic rods 23 are fixedly connected between the pressing plate 22 and the needle frame 5; the needle frame 5 is set to a transparent material to facilitate manual observation of the insertion status of the needles in the needle frame 5.

[0025] The first step: from a top-down perspective, a number of pins are manually placed in the needle frame 5 in a state of being almost parallel to the feed slot 501. The pins slide down and accumulate in the feed slot 501. The feed slot 501 can only allow one pin to pass through, so that the pins are not side by side in the feed slot 501. The bottom pin is received by the pin holder 3. Then, the needle frame 5 is manually pulled to slide on the mounting frame 4, and then the lower side of the needle frame 5 slides on the pin holder 3. When the lower side of the needle frame 5 passes through a needle slot 301, the lowest pin in the feed slot 501 will fall into the needle slot 301. After the lower side of the needle frame 5 passes through all the needle slots 301, each needle slot 301 is filled with a pin. In this way, the pins are quickly filled into the needle slots 301, replacing manual placement, improving efficiency and avoiding the appearance of redundant pins.

[0026] Step 2: manually place the socket in the socket slot 201 on the socket rack 2, with the socket's jack facing the pin rack 3, and then control the cylinder 6 to drive the mounting plate 7 and the push rod 8 to move rightward, so that the push rod 8 contacts the pin, and then drives the pin to move rightward and insert into the socket's jack to complete the assembly; then control the cylinder 6 to drive the mounting plate 7 and the push rod 8 to move leftward and reset, and finally manually remove the socket from the socket slot 201.

[0027] When the pins are placed in the pin frame 5 and slide down and accumulate in the feed slot 501, the feed slot 501 is narrow and can only allow one pin to pass through. There is a risk that the pin will get stuck in the upper part of the feed slot 501. Figure 5 As shown, the filling operation of the plug pin is affected; therefore, the needle frame 5 is set to a transparent material, and when it is manually observed that the plug pin is stuck in the upper part of the feed groove 501, the pressing plate 22 is manually pushed to compress the spring telescopic rod 23, and the pressing plate 22 drives the push plate 21 to move toward the feed groove 501, and the push plate 21 pushes the stuck plug pin into the feed groove 501, so that the plug pin can smoothly enter the feed groove 501 again, avoiding affecting the filling operation of the plug pin; after the pressing plate 22 is no longer pressed manually, due to the elastic force of the spring telescopic rod 23, the pressing plate 22 and the push plate 21 move back and reset.

[0028] Embodiment 2: Based on embodiment 1, Figure 3-Figure 4 As shown, it also includes a spring telescopic rod 2 31, a mounting plate 2 32, a connecting rod 33 and a baffle 34; a plurality of grooves 302 are opened on the pin rack 3; each groove 302 is connected to a needle groove 301 respectively; two spring telescopic rods 2 31 are fixedly connected to the right side of the pin rack 3; the telescopic ends of all the spring telescopic rods 2 31 are fixedly connected to the mounting plate 2 32; two connecting rods 33 are welded to the mounting plate 2 32; a plurality of baffles 34 are welded equidistantly between the two connecting rods 33; the baffle 34 is slidably connected to the groove 302.

[0029] Some sockets need to insert two rows of pins. The existing practice is to remove the socket from the socket frame 2 after completing the insertion of one row of pins, turn it over and then put it back into the socket frame 2, so that the socket that has not yet been inserted with the pin is located at the upper part, and then the pin is inserted. The operation is cumbersome and affects the work efficiency. Therefore, a baffle 34 is provided. After the pins are filled into the pin groove 301, they are received by the baffle 34. After each baffle 34 receives the pins, the mounting plate 2 32, the connecting rod 33 and the baffle 34 are manually pulled to move to the right. The mounting plate 2 32 stretches the spring telescopic rod 2 31 to store force, and the baffle 34 moves into the groove 302. The baffle 34 no longer receives the pins above it, and the pins fall into the bottom of the pin groove 301. Then the mounting plate 2 32 is manually released, and the spring telescopic rod 2 31 is released. Under the action of force, the mounting plate 2 32, the connecting rod 33 and the baffle plate 34 move to the left and reset, and then repeat the action of the first step, and each baffle plate 34 receives the pins. In this way, each needle groove 301 is filled with two pins, and the whole is two rows of pins, corresponding to the double-row sockets on the socket; correspondingly, two rows of push rods 8 are also provided on the mounting plate 1 7, and then the control cylinder 1 6 drives the mounting plate 1 7 and the push rod 8 to move to the right, so that the push rod 8 contacts the pins, and then drives the pins to move to the right and insert them into the socket holes of the socket to complete the assembly; the insertion and assembly of the double-row pins are completed at one time. Compared with the existing operation, there is no need to remove the socket from the socket frame 2, turn it over and then put it back into the socket frame 2. Only the mounting plate 2 32 needs to be pulled once, which is easier to operate and improves work efficiency.

[0030] Embodiment 3: Based on embodiment 2, Figure 2 , Figure 6-Figure 8 As shown, it also includes a cylinder 2 41, a mounting plate 3 42, a sliding sleeve 43, a jacket 44 and a U-shaped frame 45; two cylinders 2 41 are bolted to the mounting plate 1 7; the telescopic ends of all cylinders 2 41 are fixedly connected to the mounting plate 3 42; the mounting plate 3 42 is slidably connected to the push rod 8; a number of sliding sleeves 43 are equidistantly fixed to the mounting plate 3 42; the sliding sleeve 43 is slidably connected to the push rod 8; a jacket 44 is fixedly connected to the right end of the sliding sleeve 43, the jacket 44 is elastic, and the inner wall of the jacket 44 is roughened to increase the friction with the pin; the jacket 44 is slidably connected to the push rod 8; the base frame 1 is slidably connected to the socket frame 2; the socket frame 2 is slidably connected to the U-shaped frame 45.

[0031] In order to facilitate the sleeve 44 to slide out of the push rod 8, a guide surface 801 is provided on the push rod 8.

[0032] It also includes a base 46 and a light rod 47; the base 46 is slidably connected to the base frame 1; four light rods 47 are welded to the base 46; baffles are provided on the upper ends of all the light rods 47; all the light rods 47 are connected to the socket frame 2 in a damping sliding manner; a number of standard holes 202 are opened on the socket frame 2; each standard hole 202 is respectively matched with a push rod 8; a pressure sensor is provided at the right end of each standard hole 202; a number of LED lamp beads corresponding to the position of the standard holes 202 are provided on the upper part of the socket frame 2, and each LED lamp bead is electrically connected to the corresponding pressure sensor.

[0033] During the assembly process of the connector, it is very meaningful to conduct random inspections on the connection strength of the pins and sockets, which can not only ensure the reliability and stability of the connector, but also promptly discover and correct problems in the production process and improve production efficiency. When it is necessary to conduct random inspections on the connection strength of the pins and sockets, after the insertion of the pins is completed (at this time, the push rod 8 is still in contact with the end face of the pins), the control cylinder 2 41 drives the mounting plate 3 42, the sliding sleeve 43 and the elastic jacket 44 to move toward the pins, and the sliding sleeve 43 and the jacket 44 slide on the push rod 8, so that the jacket 44 slides out of the push rod 8 and then sleeves on the end of the pins. The inner diameter of the sleeve 44 is smaller than the diameter of the pin, so the sleeve 44 will be forced to deform by the pin, that is, the sleeve 44 will clamp the end of the pin; then, the U-shaped frame 45 is manually pulled to make the U-shaped frame 45 contact with the socket, and then the U-shaped frame 45, the socket frame 2 and the socket are driven away from the pin frame 3. If the connection strength between the pin and the socket is unqualified, the pin will be separated from the socket and the pin will remain in the sleeve 44. Otherwise, the pin will be separated from the sleeve 44; after the random inspection, the U-shaped frame 45 and the socket frame 2 are pushed back to their original positions, so that the connection strength test of the pin and the socket is completed quickly without the need for additional testing equipment, thereby improving work efficiency.

[0034] If the connection strength between the pin and the socket is unqualified, there are three problems: the length of the pin is unqualified, the diameter of the pin is too small and the diameter of the socket is too large; in order to detect the specific problem that causes the connection strength between the pin and the socket to be unqualified, when the connection strength between the pin and the socket is found to be unqualified, that is, the pin will remain in the jacket 44, the control cylinder 1 6 drives the mounting plate 1 7 and the push rod 8 to move to the left and reset, driving the pin back to the needle groove 301, and then the control cylinder 2 41 drives the mounting plate 3 42, the sliding sleeve 43 and the elastic jacket 44 to move away from the pin to reset. Then the socket frame 2 is manually pulled upward through the U-shaped frame 45, so that the socket frame 2 slides upward on the light rod 47 in a damped manner, and slides to the upper side of the socket frame 2 and contacts the baffle of the light rod 47. At this time, the standard hole 202 is opposite to the push rod 8, and then the control cylinder 16 drives the mounting plate 17 and the push rod 8 to move to the right, so that the push rod 8 pushes the pin in the needle groove 301 to move to the right and insert it into the standard hole 202 of the socket frame 2. A pressure sensor is provided at the right end of the standard hole 202. If the length of the pin is qualified, the pressure sensor will be compressed, thereby feeling the pressure, and the corresponding L The ED lamp bead will light up. If no pressure is felt, it means that the length of the pin is unqualified. Then, the control cylinder 2 41 drives the mounting plate 3 42, the sliding sleeve 43 and the elastic jacket 44 to move toward the pin. The sliding sleeve 43 and the jacket 44 slide on the push rod 8, so that the jacket 44 slides out of the push rod 8 and then sleeves on the end of the pin. The inner diameter of the jacket 44 is smaller than the diameter of the pin. Therefore, the jacket 44 will be forced to deform by the pin, that is, the jacket 44 will clamp the end of the pin. Then, the U-shaped frame 45 is manually pulled to make the U-shaped frame 45 contact with the socket, which then drives the bottom The seat 46, the bare rod 47, the socket frame 2 and the socket are away from the pin frame 3. If the connection strength between the pin and the standard hole 202 is unqualified, the pin will be separated from the standard hole 202, and the pin will be pulled out of the standard hole 202 and remain in the jacket 44. Otherwise, the pin will remain in the standard hole 202. If the pin is pulled out of the standard hole 202, it means that the diameter of the pin is too small; if the pin remains in the standard hole 202, it means that the diameter of the pin is qualified, but the socket hole diameter of the socket is too large; in this way, the specific problem that causes the unqualified connection strength between the pin and the socket is detected.

[0035] An assembly method for connector production comprises the following steps: Step 1: Filling the pins. From a bird's-eye view, manually place a number of pins in the pin frame 5 in a state that is almost parallel to the feed slot 501, so that the pins are not arranged side by side in the feed slot 501, and the pins at the bottom are received by the pin holder 3. Then, manually pull the pin frame 5 to slide on the mounting frame 4, and then slide the lower side of the pin frame 5 on the pin holder 3. When the lower side of the pin frame 5 passes through a pin slot 301, the pin at the bottom of the feed slot 501 will fall into the pin slot 301, so that the pins are quickly filled into the pin slot 301. Step 2: Place the socket manually in the socket slot 201 on the socket rack 2, with the socket hole facing the pin rack 3; Step 3: Assemble, control cylinder 6 to drive mounting plate 7 and push rod 8 to move to the right, so that push rod 8 contacts the pin, and then drive push rod 8 to move to the right and insert it into the socket hole to complete the assembly; then control cylinder 6 to drive mounting plate 7 and push rod 8 to move to the left to reset, and finally manually remove the socket from the socket slot 201.

10. An assembly method for connector production, characterized in that: The method is based on the assembly equipment for connector production according to claim 9, comprising the following steps: Step 1: Filling the pins. From a top-down perspective, a plurality of pins are manually placed in the pin frame (5) in a state that they are almost parallel to the feed slot (501), so that the pins are not arranged side by side in the feed slot (501), and the pins at the bottom are received by the pin holder (3). Then, the pin frame (5) is manually pulled to slide on the mounting frame (4), thereby sliding the lower side of the pin frame (5) on the pin holder (3). When the lower side of the pin frame (5) passes through a pin slot (301), the pin at the bottom of the feed slot (501) will fall into the pin slot (301), thereby quickly filling the pins into the pin slot (301); Step 2: placing the socket manually in the socket slot (201) on the socket rack (2), with the socket hole facing the pin rack (3); Step 3: Assembling, control the cylinder 1 (6) to drive the mounting plate 1 (7) and the push rod (8) to move to the right, so that the push rod (8) contacts the pin, and then drives the push rod (8) to move to the right and insert it into the socket hole, thus completing the assembly; then control the cylinder 1 (6) to drive the mounting plate 1 (7) and the push rod (8) to move to the left to reset, and finally manually remove the socket from the socket slot (201).
