Technical Field

[0001] The invention relates to an automatic assembly system, in particular to a resistor assembly device. Background Art

[0002] The description in this section merely provides background information related to the present disclosure and does not constitute prior art.

[0003] A resistor needs to be assembled. The initial state is a resistor body with a metal wire strung through it. To achieve the finished product, the heads at both ends of the resistor need to be bent and then riveted into the terminals, and the resistor body needs to be shaped into a preset shape.

[0004] The existing assembly of the above resistors usually adopts manual assembly, which has low precision and slow installation speed, resulting in low production efficiency and the output of a large number of unqualified resistor products. Or it is assembled through an automated assembly line, but due to the large number of bending steps and complex positioning process, the layout of the assembly line is unscientific, and the efficiency and yield rate are also difficult to meet the standards.

[0005] There is no resistor assembly device that can solve the above problems at present. Summary of the invention

[0006] The purpose of the present invention is to provide a resistor assembly device to solve the current problem of low resistor assembly accuracy and slow speed.

[0007] In order to achieve the above-mentioned object, the present invention discloses the following resistor assembly device, which is used to rivet the resistor in a first terminal and a second terminal and perform shaping, wherein the resistor has a first end and a second end opposite to each other, the first end of the resistor corresponds to the first terminal, and the second end of the resistor corresponds to the second terminal; the resistor assembly device comprises:

[0011] An installation part, the installation part is connected to the first feeder, the second feeder and the third feeder respectively;

[0012] A conveyor belt, which can transport the resistor between different areas of the mounting portion through a carrier;

[0013] Wherein, the installation part includes:

[0014] A bending mechanism, the bending mechanism is connected to the third feeder, and the bending mechanism is used to bend the first end and the second end of the resistor;

[0015] a first mounting mechanism, the first mounting mechanism being connected to the first feeder, the first mounting mechanism being used to rivet the first end of the resistor into the first terminal;

[0016] a second mounting mechanism, the second mounting mechanism being connected to the second feeder, the second mounting mechanism being used to rivet the second end of the resistor into the second terminal;

[0017] A first forming mechanism, the first forming mechanism is used to first form the two ends of the resistor to which the first terminal and the second terminal are riveted;

[0018] a second molding mechanism, wherein the first molding mechanism is used to perform a second molding on the two ends of the resistor to which the first terminal and the second terminal are riveted;

[0021] The cutting robot arm has a tool that can move along the direction of the carrier, and the carrier has a tool groove that matches the size of the tool. When the carrier transfers the resistor to the position of the cutting robot arm, the bending fixture presses down and presses the middle position of the resistor onto the carrier, and then the tool is pressed down into the tool groove, so that the plastic sheet wrapped around the resistor is cut by the tool;

[0022] The first bending robot arm includes a first bending fixing frame and a first bending roller. When the carrier transfers the resistor to the position of the first bending robot arm, the bending fixture is pressed down and the middle position of the resistor is pressed against the carrier, and then the first bending fixing frame is pressed down and the first end of the resistor is fixed on the carrier, and the first bending roller is made to vertically push the first end of the resistor, so that the first end of the resistor is bent 90 degrees relative to the first bending fixing frame at the corresponding position;

[0023] The second bending robot arm includes an angle fixing frame and a second bending roller. When the carrier transfers the resistor to the position of the second bending robot arm, the angle fixing frame clamps the resistor along a bending direction perpendicular to the first end of the resistor to achieve the angle positioning of the resistor, and then the bending clamp is pressed down and presses the middle position of the resistor onto the carrier, and then the angle fixing frame detaches from the resistor to avoid the second bending roller, and allows the second bending roller to push the first end of the resistor in parallel, so that the first end of the resistor is finally bent 180 degrees.

Then the first riveting machine is pressed down toward the first riveting base, so that the first end of the resistor is riveted in the first terminal. Then the first retrieval clamp re-grasps the resistor connected to the first terminal, rotates it once, and then turns the first end and the second end of the resistor around each other, and then puts it back on the carrier.

[0028] The second mounting clamp is used to transfer the bent resistor on the carrier to the second push platform. At the same time, the second feeder pushes the second terminal to the second riveting base. Then the hydraulic cylinder arranged on one side of the second push platform pushes the second push platform toward the second riveting base, so that the second end of the resistor on the second push platform is inserted into the second terminal on the second riveting base. Then the second riveting machine is pressed downward toward the second riveting base, so that the second end of the resistor is riveted in the second terminal. Then the second retrieval clamp grabs the resistor connected with the first terminal and the second terminal back to the carrier.

[0029] Further, the first forming mechanism includes a first shaping fixture, a first slide table and a first shaping machine table;

[0030] The first shaping fixture is used to clamp the carrier carrying the resistor connected to the first terminal and the second terminal and place it on the first slide, and then the first slide is displaced so that the carrier on the first slide is pushed under the first shaping machine, and the first shaping machine is pressed down so that the first limit clamp at the bottom of the first shaping machine clamps the resistor, and then the first shaping machine moves relative to the carrier so that the multiple first rollers at the bottom of the first shaping machine bend the first end and the second end of the resistor with the two sides of the first limit clamp as the center, wherein the bending position of the first shaping is set at the position where the resistor is adjacent to the first terminal and the second terminal.

[0031] Further, the second molding mechanism includes a second shaping fixture, a second slide table and a second shaping machine table;

[0032] The second shaping fixture is used to clamp the carrier carrying the resistor connected with the second terminal and the second terminal and place it on the second slide, and then the second slide is displaced so that the carrier on the second slide is pushed to the bottom of the second shaping machine, and the second shaping machine is pressed down so that the second limit clamp at the bottom of the second shaping machine clamps the resistor, and then the second shaping machine moves relative to the carrier in an offset manner so that the multiple second rollers at the bottom of the second shaping machine bend the second end and the second end of the resistor by the multiple second rollers with the two sides of the second limit clamp as the center, wherein the bending position of the second shaping is set at the bending position of the first shaping towards the middle of the resistor, and the bending direction of the first shaping is opposite to the bending direction of the second shaping.

[0033] Further, the third molding mechanism includes a third shaping fixture, a third slide table and a third shaping machine table;

[0034] The third shaping fixture is used to clamp the carrier carrying the resistor connected to the third terminal and the third terminal and place it on the third slide, and then the third slide is displaced so that the carrier on the third slide is pushed under the third shaping machine, and the third shaping machine is pressed down so that the third limiting clamp at the bottom of the third shaping machine clamps the resistor, and then the third shaping machine moves relative to the carrier, so that the multiple third rollers at the bottom of the third shaping machine bend the third end and the third end of the resistor with the two sides of the third limiting clamp as the center by the multiple third rollers, wherein the position of the third shaping bend is the same as the position of the second shaping bend, and finally the first end and the second end of the resistor are bent to a parallel state.

[0035] Furthermore, downstream of the third forming mechanism, there is also a detection unit connected to the conveyor belt, the detection unit includes an image detection machine, a detection clamp and a material receiving box, the carrier is transported to the bottom of the image detection machine for temporary detection, and then the detection clamp sorts the resistor connected to the first terminal and the second terminal on the carrier after detection into good and defective products into the material receiving box.

[0036] Furthermore, the carrier is provided with embedding grooves for embedding a plurality of the resistors, so that the same carrier can transport a plurality of the resistors at the same time.

[0054] See also Figure 1 , is a resistor assembly device of this embodiment, used for riveting a resistor 100 in a first terminal 200 and a second terminal 300 and shaping the resistor 100, wherein the resistor 100 has a first end and a second end opposite to each other, the first end of the resistor 100 corresponds to the first terminal 200, and the second end of the resistor 100 corresponds to the second terminal 300; wherein the resistor assembly device includes:

[0055] A first feeder 1, the first feeder 1 being equipped with a first terminal 200 to be installed;

[0056] The second feeder 2 is provided with a second terminal 300 to be installed.

[0057] The third feeder 3 is equipped with a resistor 100 to be installed;

[0058] A mounting part 4, which is respectively connected to the first feeder 1, the second feeder 2 and the third feeder 3;

[0059] A conveyor belt 5 , which can convey the resistor 100 between different areas of the mounting portion 4 via a carrier 51 ;

[0060] The mounting portion 4 includes the following components which are arranged in sequence upstream and downstream along the moving direction of the conveying belt 5:

[0061] A bending mechanism 41, the bending mechanism 41 is connected to the third feeder 3, and the bending mechanism 41 is used to bend the first end and the second end of the resistor 100;

[0062] A first mounting mechanism 42, the first mounting mechanism 42 is connected to the first feeder, and the first mounting mechanism 42 is used to rivet the first end of the resistor into the first terminal;

[0063] A second mounting mechanism 43, the second mounting mechanism 43 is connected to the second feeder, and the second mounting mechanism 43 is used to rivet the second end of the resistor into the second terminal;

[0064] A first molding mechanism 44, the first molding mechanism 44 is used for first molding the two ends of the resistor 100 riveted with the first terminal 200 and the second terminal 300;

[0065] The second molding mechanism 45 is used for molding the two ends of the resistor 100 riveted with the first terminal 200 and the second terminal 300 for the second time;

[0066] The third molding mechanism 46 is used to perform a third molding on the two ends of the resistor 100 riveted with the first terminal 200 and the second terminal 300 .

[0067] First, see Figure 2-3 The resistor 100 to be processed in this embodiment is a main body with a cylindrical center and metal wires passing through the two ends. The metal wires at the first end and the second end need to be folded inward 180 degrees and riveted to the corresponding first terminal 200 and the second terminal 300 respectively, and the resistor 100 with the first terminal 200 and the second terminal 300 riveted thereto is further shaped multiple times to be folded into the following shape: Figure 3 Finished look shown.

[0068] Through the above structure, when in use, the operator only needs to put a preset amount of resistors 100 into the third feeder 3, and put a matching number of first terminals 200 into the first feeder 1, and a matching number of second terminals 300 into the second feeder 2, and then the device can be started. The third feeder 3 transports the resistors 100 connected by the plastic structure to the installation part 4, and the bending mechanism 41 in the installation part 4 first pre-processes the resistors 100, and the bending fixture 411 cuts off the plastic on the resistor 100, and then the cutting robot arm 412 and the second bending robot arm 414 fold the first end and the second end of the resistor 100 twice, respectively, so that the first end and the second end of the resistor 100 form an inwardly bent annular buckle structure, and then, the bent resistor 100 runs along the conveyor belt 5, and the first feeder 1 delivers the first terminal 200 to the first installation mechanism 42, and the first installation mechanism 42 inserts the first end of the bent resistor 100 The resistor 100 is riveted to the first terminal 200 and riveted. Similarly, the resistor 100 riveted to the first terminal 200 runs along the conveyor belt 5, and the second feeder 2 delivers the second terminal 300 to the second installation mechanism 43. The second installation mechanism 43 inserts the second end of the resistor 100 riveted to the first terminal 200 into the second terminal 300 and rivets it, so that both ends of the resistor 100 are riveted with a terminal; then, the resistor 100 riveted to the first terminal 200 and the second terminal 300 continues to pass through the first forming mechanism 44, the second forming mechanism 45 and the third forming mechanism 46 in sequence, so that the metal wire of the resistor 100 is shaped and bent to a preset shape, and finally completed and shipped.

[0069] In the above processing process, the device first bends the first end and the second end of the resistor 100 in batches, and then welds the terminals of the first end and the second end of the bent resistor 100, and finally successively and step by step, the metal wire part of the relatively fragile resistor 100 is bent in three steps to perform overall shaping, so that the resistor 100 can achieve the final shaping more accurately, which greatly improves the efficiency compared with manual assembly, and the scientific step-by-step division ensures that the resistor 100 will not be deformed during the assembly process, the installation accuracy is high, and defective products are not easy to appear.

[0070] For further information, see Figure 4-5 The bending mechanism 41 includes a bending fixture 411, and a cutting robot arm 412, a first bending robot arm 413, and a second bending robot arm 414 arranged along one side of the forward direction of the carrier 51; see Figure 4 The cutting robot arm 412 has a tool 4121 that can move along the direction of the carrier 51, and the carrier 51 has a tool groove that matches the size of the tool 4121. When the carrier 51 transfers the resistor 100 to the position of the cutting robot arm 412, the bending fixture 411 is pressed down and presses the middle position of the resistor 100 onto the carrier 51, and then the tool 4121 is pressed down into the tool groove, so that the plastic sheet wrapped around the resistor 100 is cut by the tool 4121; by first pressing the bending fixture 411 down to fix the resistor 100, and then dropping the tool to cut the plastic of the resistor 100, it can effectively prevent the resistor 100 from shaking during the cutting process, which may cause accidental damage to the resistor 100 itself. The first bending robot arm 413 includes a first bending fixing frame 4131 and a first bending roller 4132. When the carrier 51 transfers the resistor 100 to the position of the first bending robot arm 413, the bending clamp 411 is pressed down and the middle position of the resistor 100 is pressed against the carrier 51, and then the first bending fixing frame 4131 is pressed down and the first end of the resistor 100 is fixed on the carrier 51, and the first bending roller 4132 is made to vertically push the first end of the resistor 100, so that the first end of the resistor 100 is bent 90 degrees relative to the first bending fixing frame 4131 at the corresponding position; in the above process, the middle position of the resistor 100 is first fixed by means of the bending clamp 411, and then the resistor 100 is fixed for the second time by means of the first bending fixing frame 4131, so that the positioning accuracy of the resistor 100 before bending is improved on the basis of double fixation.

[0071] The second bending robot arm 414 includes an angle fixing frame 4141 and a second bending roller 4142. When the carrier 51 transfers the resistor 100 to the position of the second bending robot arm 414, the angle fixing frame 4141 clamps the resistor 100 along the bending direction perpendicular to the first end of the resistor 100 to achieve the angle positioning of the resistor 100, and then the bending clamp 411 is pressed down and presses the middle position of the resistor 100 onto the carrier 51, and then the angle fixing frame 4141 is separated from the resistor 100 to avoid the second bending roller 4142, and the second bending roller 4142 pushes the first end of the resistor 100 in parallel, so that the first end of the resistor 100 is finally bent 180 degrees. In the above process, the angle fixing frame 4141 is configured as two independent squeezing devices that can move from the to-be-bent area of ​​the resistor 100 toward the resistor 100, and the gap in the middle of the angle fixing frame 4141 at the clamping point of the resistor 100 has a preset angle, so that the resistor 100 can be rotated and precisely positioned under the squeezing of the angle fixing frame 4141, and then the bending fixture 411 is repeatedly pressed down so that after the angle fixing frame 4141 is detached, the resistor 100 still maintains a precise positioning angle, and finally, the second bending roller 4142 squeezes the first end of the resistor 100 along the extension direction of the resistor 100, so that the first end of the resistor 100 is completely bent.

[0072] Similarly, see Figure 1 The bending mechanism 41 also includes another set of cutting mechanical arms 412, first bending mechanical arms 413 and second bending mechanical arms 414 arranged along one side of the forward direction of the carrier 51, so that the first end of the resistor 100 is cut, bent 90 degrees and 180 degrees in sequence, while the second end of the resistor 100 is cut, bent 90 degrees and 180 degrees synchronously. It is worth noting that in the above process, the two sets of symmetrically arranged cutting mechanical arms 412, first bending mechanical arms 413 and second bending mechanical arms 414 share a bending fixture 411, and the bending fixture 411 is located above the middle position of the two sets of cutting mechanical arms 412, first bending mechanical arms 413 and second bending mechanical arms 414. During the processing, the bending fixture 411 synchronously processes and positions the first end and the second end of the resistor 100, so that the processing efficiency is improved.

[0073] For further information, see Figure 1 and Figure 6 , the first mounting mechanism 42 includes a first mounting clamp 421, a first push platform 422, a first riveting machine 423, a first riveting base 424 and a first retrieval clamp 425;

[0074] The first mounting clamp 425 is used to transfer the bent resistor 100 on the carrier 51 to the first push platform 422. At the same time, the first feeder 1 pushes the first terminal 200 onto the first riveting base 424. Then the hydraulic cylinder arranged on one side of the first push platform 422 pushes the first push platform 422 toward the first riveting base 424, so that the first end of the resistor 100 on the first push platform 422 is inserted into the first terminal 200 on the first riveting base 424. Then the first riveting machine 423 is pressed downward toward the first riveting base 424, so that the first end of the resistor 100 is riveted into the first terminal 200. Then the first retrieval clamp 425 re-grasps the resistor 100 connected to the first terminal 200, rotates it once, and turns the first end and the second end of the resistor 100 around each other, and then puts it back on the carrier 51. It is worth noting that in the above process, after the first mounting clamp 421 places the resistor 100 on the first push platform 422, the first riveting machine 423 is in a raised state, so that there is enough space under the first riveting machine 423 to accommodate the first terminal 200 transmitted from the first feeder 1 to the first riveting base 424, and then the hydraulic cylinder pushes the first end of the resistor 100 and inserts it into the first terminal 200 on the first riveting base 424. Figure 3 As shown, the first terminal 200 is in a relaxed state with the first end of the resistor 100 in an initial state without limiting each other. After riveting, the claw-shaped portion of the first terminal 200 is deformed, so that the first end of the resistor 100 is tightly clamped by the claw-shaped portion of the deformed first terminal 200. Specifically, the head of the first riveting machine 423 used for riveting is consistent with the outer contour of the deformed terminal 200. Similarly, after the first terminal 200 is installed, the above steps can be repeated through the second installation mechanism 43 with a similar structure, so that the second terminal 300 can be installed to the second end of the resistor 100. Of course, it is worth noting that after the first terminal 200 is riveted and fixed, and rotated once, the first retrieval clamp 425 drives the first end and the second end of the resistor 100 to turn around each other. Only by a rotating motor between the first retrieval clamp 425, the second installation mechanism 43 can maintain almost the same structural design and layout as the first installation mechanism 42, which significantly saves costs.

[0075] For further information, see Figure 7The first forming mechanism 44 includes a first shaping fixture 441, a first slide 442 and a first shaping machine 443; the first shaping fixture 441 is used to clamp and place the carrier 51 carrying the resistor 100 connected to the first terminal and the second terminal on the first slide 442, and then the first slide 442 is displaced so that the carrier 51 on the first slide 442 is pushed to the bottom of the first shaping machine 443, and the first shaping machine 443 is pressed down so that the first limiting clamp 4431 at the bottom of the first shaping machine 443 clamps the resistor 100, and then the first shaping machine 4431 moves relative to the carrier 51, so that the multiple first rollers 4432 at the bottom of the first shaping machine 443 bend the first end and the second end of the resistor 100 with the two sides of the first limiting clamp 4431 as the center by the multiple first rollers 4432, wherein the bending position of the first shaping is set at the position of the resistor 100 near the first terminal and the second terminal. Through the above structure and steps, the originally straight metal wire of the resistor 100 is slightly bent into an eight-shaped shape, the first shaping machine 4431 and the first roller 4432 are clamped stably, and the mold cost is low.

[0076] Similarly, if Figure 8 As shown, in the second forming mechanism 45, with the cooperation of the second limiting clamp 4531 and the second roller 4532, the second shaping and bending of the metal wire of the resistor 100 is realized. Specifically, in the process of the second shaping machine 453 driving the second roller 4532 to slide relative to the clamped resistor 100, the second limiting clamp 4531 is arranged on the inner side of the second roller 4532. With the push of the second roller 4532, the first end and the second end of the resistor 100 form a turn in the opposite direction on the inner side of the first shaping position to match the prefabricated shape of the second limiting clamp 4531. Fig. 9 As shown, in the third forming mechanism 46, the third limiting clamp 4631 and the third roller 4632 further bend the bent position again based on the second bending position, and the bending direction is the same, so as to finally achieve the following Figure 3 The bending angle of the final finished resistor 100 is shown so that the first end and the second end of the resistor 100 are arranged parallel to each other. With the above three steps of shaping, the possibility of accidental deformation and breakage of the resistor 100 that may occur during the shaping process is avoided to the greatest extent, so that the shaping accuracy of the resistor 100 is higher.

[0077] Further, the downstream of the third forming mechanism 46 also includes a detection unit 47 connected to the conveyor belt 5, and the detection unit 47 includes an image detection machine, a detection clamp and a material receiving box. The carrier 51 is transported to the bottom of the image detection machine for temporary detection, and then the detection clamp sorts the resistors connected to the first terminal and the second terminal on the detected carrier into good and defective categories into the material receiving box. Specifically, during use, when the image detection machine of the detection unit 47 detects that the resistor 100 riveted with the first terminal 200 and the second terminal 300 on the carrier 51 passing here does not meet the preset requirements, the detection clamp will later grab the defective product and place it in the defective product storage area of ​​the material receiving box. On the contrary, when the image detection machine of the detection unit 47 detects that the resistor 100 riveted with the first terminal 200 and the second terminal 300 on the carrier 51 passing here meets the preset requirements, the detection clamp will later grab the good product and place it in the good product storage area of ​​the material receiving box.

[0078] Of course, in this embodiment, if Figure 1-2 As shown, the carrier 51 is provided with embedding grooves for embedding multiple resistors 100, so that the same carrier 51 can transport multiple resistors at the same time. The embedding groove itself mainly matches the cylindrical part in the middle position of the resistor 100, and plays a role of limiting the resistor 100. That is to say, in this embodiment, different sizes of carriers 51 or different numbers of carriers 51 can be set as needed to perform simultaneous assembly operations on multiple resistors 100 to meet the requirements of processing efficiency.
