Description

Technical Field

[0001] This invention relates to the field of resistor processing, and in particular to a glue removal device for tape and reel resistors. Background Technology

[0002] Adding an encapsulation layer to vulnerable parts of a resistor can increase its physical protection, preventing damage from impacts or scratches during transportation, assembly, or use.

[0003] Because the viscosity of adhesive decreases and its flow properties increase after heating, whether dispensing manually or using a dispensing machine, the adhesive tends to overflow from the side of the component during the encapsulation process, creating redundant adhesive on the resistor surface, especially in cases like... Figure 1 The tape-and-reel resistor 20 shown has small gaps between the resistors 22 on the tape 21. During the encapsulation process, adhesive can easily flow into the gaps between adjacent resistors 22. When using the tape-and-reel resistor 20, the resistors 22 need to be removed from the tape 21. This causes the adhesive 23 between adjacent resistors 22 to crack, further causing the encapsulation layer on the side of the resistor 22 to detach, resulting in incomplete encapsulation on the surface of the resistor 22. To ensure the integrity of the encapsulation layer, residual adhesive needs to be removed using an adhesive removal device.

[0004] Existing adhesive removal devices have the following problems: 1. When the tape resistors 20 to be de-adhesive are stacked in the material trough, the bottom tape resistor 20 needs to be pushed into the de-adhesive device by the pusher block. In this feeding method, the weight of the upper tape resistors 20 acts on the bottom tape resistors 20, so the tape resistors 20 pushed by the pusher block will not jump. However, the feeding process will cause the number of tape resistors 20 in the material trough to decrease continuously. This will reduce the pressure applied to the bottom tape resistors 20. That is, when the number of tape resistors 20 remaining in the material trough is too small, the feeding process will be unstable. In addition, the tape resistors 20 are tape-shaped and have a small mass. As the tape resistors 20 descend along the material trough, they are prone to warping and tilting due to friction with the trough wall.

[0005] 2. After the tape resistors to be degummed 20 are fed into the material tank, they need to be refilled. During the process of stacking new tape resistors into the material tank, the degumming equipment is in standby mode, which affects the degumming efficiency. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a glue removal device for tape and reel resistors, which removes redundant glue remaining in the gaps between resistors during the encapsulation process and improves the encapsulation accuracy of tape and reel resistors.

[0007] The objective of this invention is achieved through the following technical solution: A glue removal device for tape and reel resistors, comprising: a transmission track and a feeding assembly and a punching head located on the transmission track; The feeding assembly includes a cutting cylinder, a feeding plate, a storage bin, a lifting cylinder, and a conveyor belt. The conveyor track has a through hole, and the wall of the through hole is provided with an elastic support. The lifting cylinder and the storage bin are located at the two openings of the through hole. The conveyor belt is used to feed the tape resistor to the lifting cylinder. The lifting cylinder pushes the tape resistor through the through hole and into the storage bin. The bottom of the storage bin is connected to the transmission track. The cutting cylinder drives the feeding plate to push the tape resistor located at the bottom of the storage bin so that the tape resistor enters the transmission track. The transmission track is used to drive the tape-and-reel resistor to move horizontally. The punch head is suspended above the transmission track and is used to press down to remove excess adhesive on the tape-and-reel resistor.

[0008] In one embodiment, the storage bin includes two limiting frames with a "C"-shaped cross-section, the two limiting frames being arranged facing each other, and the tape-and-reel resistors to be de-adhesive are stacked and housed between the two limiting frames.

[0009] In one embodiment, each of the limiting frames is provided with an elastic presser, which includes a central shaft, a pressure block, and an elastic sheet. The limiting frame is provided with a communicating groove and a storage cavity. The groove extends from the top to the bottom of the limiting frame. The central shaft is slidably disposed in the groove, and the pressure block passes through the central shaft, with the end of the pressure block extending into the storage cavity. The elastic sheet is wound around the central shaft, and a hook is provided at the end of the elastic sheet. The hook is connected to the bottom of the limiting frame, and the elastic sheet provides elastic force to drive the central shaft to slide towards the bottom of the limiting frame.

[0010] In one embodiment, there is a gap between the groove and the elastic sheet, and the unwound portion of the elastic sheet is bent and abuts against the inner wall of the groove.

[0011] In one embodiment, an anti-deflection protrusion is provided on the side of the pressure block away from the bottom of the limiting frame. The anti-deflection protrusion abuts against the inner wall of the limiting frame and is used to prevent the pressure block from rotating.

[0012] In one embodiment, a clearance area is provided on the pressure block at the position where it is connected to the central axis, and the rolled-up portion of the elastic sheet is located within the clearance area.

[0013] In one embodiment, the feeding assembly further includes a stacking bin located below the storage bin. The stacking bin has an inlet at a position where it connects to the conveyor belt. The lifting cylinder is located inside the storage bin, and a material carrier plate is provided on the output end of the lifting cylinder. The material carrier plate is in contact with the inner wall of the storage bin.

[0014] In one embodiment, the number of tape-and-reel resistors that the stacking bin can hold is less than the number of tape-and-reel resistors that the storage bin can hold.

[0015] In one embodiment, the stamping head is provided with a plurality of contouring pressure teeth.

[0016] In one embodiment, multiple elastic supports are provided, a spring is provided between the elastic support and the inner wall of the through hole, and an inclined surface is provided on the side of the elastic support facing the lifting cylinder.

[0017] The above-mentioned adhesive removal device for tape and reel resistors has the following beneficial effects: 1. The conveyor belt and the lifting cylinder work together to stack the tape resistors to be degummed below the storage bin. The lifting cylinder pushes the stacked tape resistors into the storage bin, and the cutting cylinder pushes the resistors at the bottom of the storage bin into the conveyor track. The product stacking and product loading processes are independent of each other and can be carried out simultaneously without interference, which helps to improve the loading efficiency of the products to be degummed. 2. The lifting cylinder can fill the stacked tape resistors into the storage bin from below. By replenishing the tape resistors in the storage bin, the problem of unstable feeding process caused by insufficient product quantity can be avoided. Attached Figure Description

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Please see Figure 2 and Figure 3This invention provides a de-adhesive removal device 10 for tape and reel resistors, comprising: a transport track 100, a feeding assembly 200, and a punching head 300 located on the transport track 100. The feeding assembly 200 is used to move the tape and reel resistors 20 to be de-adhesive removed one by one into the transport track 100. The transport track 100 drives the tape and reel resistors 20 to move horizontally, and the punching head 300 performs a punching operation to remove the adhesive 23 remaining on the tape and reel resistors 20 due to the encapsulation process.

[0025] Please see Figure 4 and Figure 5 The feeding assembly 200 includes a cutting cylinder 210, a feeding plate 220, a storage bin 230, a lifting cylinder 240, and a conveyor belt 250. A through hole 110 is provided on the conveyor track 100, and an elastic support 120 is provided on the wall of the through hole 110. The lifting cylinder 240 and the storage bin 230 are located at the two openings of the through hole 110. The conveyor belt 250 is used to feed the tape-type resistors 20 to the lifting cylinder 240. The tape-type resistors 20 fall from the end of the conveyor belt 250 and stack on the lifting cylinder 240. This process occurs in the storage bin 230. The process is carried out below 0. While the tape and reel resistors 20 are stacked, the cutting cylinder 210 continuously pushes the tape and reel resistors 20 at the bottom of the storage bin 230 into the transmission track 100 through the feeding plate 220 for feeding. In this way, the product stacking action and the feeding action are carried out simultaneously at the two openings of the through hole 110 without interfering with each other. The lifting cylinder 240 can push the stacked tape and reel resistors 20 through the through hole 110 and into the storage bin 230, so that the storage bin 230 always stores tape and reel resistors 20 to be fed, maintaining the continuity of feeding.

[0026] The bottom of the storage bin 230 is connected to the transmission track 100. The cutting cylinder 210 drives the feeding plate 220 to push the tape resistor 20 located at the bottom of the storage bin 230 so that the tape resistor 20 enters the transmission track 100. That is, each time the feeding action is performed, the tape resistor 20 located at the bottom of the storage bin 230 is pushed out.

[0027] Please see Figure 2 and Figure 3 The transmission track 100 is used to drive the tape-type resistor to move horizontally. The punch head 300 is suspended above the transmission track 100. The punch head 300 presses down to cut off the redundant adhesive 23 on the tape-type resistor. The punch head 300 is provided with a contouring tooth 310. The contouring tooth 310 is aligned with the gap between the resistors in the tape-type resistor 20. When the punch head 300 presses down, the contouring tooth 310 punches and cuts the adhesive 23.

[0028] Please see Figure 4 and Figure 5It can be seen that the stacking and feeding actions of the tape resistors 20 in the above-mentioned adhesive removal device 10 for tape resistors are performed independently. When the number of products in the storage bin 230 decreases, the stacked tape resistors 20 are filled into the storage bin 230 to avoid the problem that the bottom tape resistors 20 are not supported enough after the number of products in the storage bin 230 decreases, which would cause the cutting cylinder 210 to fail to perform the feeding action normally. However, this feeding method only ensures that the products at the bottom of the storage bin 230 are kept flat during the feeding process. The tape resistors 20 at the top have low pressure resistance. During the feeding process, the stacked product height in the storage bin 230 is constantly decreasing. The tape resistors 20 at the top are prone to displacement due to their low pressure resistance. When the outer wall of the tape resistor 20 scrapes against the inner wall of the storage bin 230, the tape resistors 20 at the top are still prone to tilting and flipping. Furthermore, because the feeding process needs to prevent the tape resistors 20 from tilting or deflecting when the cutting cylinder 210 pushes the material laterally, it is necessary to ensure that there are always other products above the pushed tape resistors 20 to compact them. This requires that there are always residual tape resistors 20 in the storage bin 230. Since the lifting cylinder 240 fills the new product from bottom to top when replenishing, the aforementioned residual tape resistors 20 will always remain in the upper layer of the storage bin 230. This part of the product can never complete the degumming operation.

[0029] Please see Figure 6 To solve the above problems, the storage bin 230 includes two limiting frames 231 with a "C" shaped cross section. The two limiting frames 231 are arranged facing each other, and the tape-type resistors 20 to be de-adhesive are stacked and housed between the two limiting frames 231.

[0030] Please see Figure 6 and Figure 7 Each limiting frame 231 is provided with an elastic presser 270. The elastic presser 270 includes a central shaft 271, a pressing block 272 and an elastic sheet 273. The limiting frame 231 is provided with a connected sliding groove 11 and a storage cavity 12. The two ends of the tape resistor 20 extend into the storage cavities 12 of the two limiting frames 231 respectively. The middle part of the tape resistor 20 is exposed, providing movable space for the feeding plate 220. When feeding, the feeding plate 220 extends between the two limiting frames 231 and contacts the middle position of the tape resistor 20, and applies a pushing force to push it into the transmission track 100.

[0031] The chute 11 extends from the top to the bottom of the limiting frame 231. The central shaft 271 is slidably disposed in the chute 11, and the central shaft 271 passes through the pressure block 272. The pressure block 272 can slide along the chute 11 from the top to the bottom of the limiting frame 231, and the end of the pressure block 272 extends into the storage cavity 12 and contacts the tape resistor 20. The tape resistors 20 located in the storage bin 230 are stacked together, and the pressure block 272 contacts the tape resistor 20 located on the top layer.

[0032] The elastic sheet 273 is wound around the central shaft 271. The end of the elastic sheet 273 is provided with a hook 274, which is connected to the bottom of the limiting frame 231. The cross-section of the elastic sheet 273 is vortex-shaped. When force is applied, the elastic sheet 273 can be pulled out from the central shaft 271. When the external force is removed, the elastic sheet 273 can be wound back onto the central shaft 271 under its own elastic force. In this way, after the hook 274 is fixed to the bottom of the limiting frame 231, the elastic force provided by the elastic sheet 273 will drive the central shaft 271 to move to the bottom of the limiting frame 231. When the tape-type resistor 20 is filled into the storage bin 230, the pressure block 272 is lifted by the tape-type resistor 20 entering the storage bin 230. At this time, the central shaft 271 slides to the top of the limit frame 231, the elastic sheet 273 is stretched, and the elastic force generated by the elastic sheet 273 is reacted on the tape-type resistor 20 through the pressure block 272. The elastic force provided by the elastic sheet 273 is used to press the tape-type resistor 20 to be de-adhesive into the storage bin 230. Even if there is only one tape-type resistor 20 left in the storage bin 230, the cutting cylinder 210 can feed it smoothly.

[0033] There is a gap between the slide groove 11 and the elastic sheet 273, and the unwound portion of the elastic sheet 273 is bent and abuts against the inner wall of the slide groove 11.

[0034] The principle by which the above-mentioned elastic presser 270 prevents malfunctions during the feeding process of the tape-type resistor 20 is as follows: When the lifting cylinder 240 pushes the stacked tape resistors 20 into the storage hopper 230, the end of the pressure block 272 extends into the storage cavity 12, and the uppermost tape resistor 20 comes into contact with the pressure block 272. As the lifting cylinder 240 pushes the pressure block 272 up together, the spindle 271 moves up along the slide groove 11 during this process, and the elastic sheet 273 is stretched. The elastic force generated by the elastic sheet 273 drives the pressure block 272 to press on the uppermost tape resistor 20.

[0035] After the lifting cylinder 240 is reset, the cutting cylinder 210 is started, pushing the bottom layer of tape resistors 20 into the transmission track 100. The number of tape resistors 20 stacked in the storage bin 230 decreases continuously as the cutting cylinder 210 moves. The pressure block 272 always presses down on the top layer of tape resistors 20 to provide downward pressure. During this process, the elastic sheet 273 continuously rolls up the stretched part until the tape resistors 20 in contact with the pressure block 272 are pushed into the transmission track 100.

[0036] When not subjected to external force, the elastic sheet 273 is wound around the central shaft 271 under its own elastic force. The cross-section of the elastic sheet 273 is vortex-shaped, meaning that in its natural state, the elastic sheet 273 will bend under its own elastic force. The stretched part of the elastic sheet 273 will also bend under its own elastic force. The hook 274 on the elastic sheet 273 is fixed to the bottom of the limiting frame 231, and the elastic sheet 273 is wound around the central shaft 271. The central shaft 271 can only slide along the slide groove 11. This allows the stretched part to abut against the inner wall of the slide groove 11 when it bends. That is, part of the elastic force generated when the stretched part retracts will act on the inner wall of the slide groove 11, thus avoiding excessive elastic force applied to the tape resistor 20.

[0037] Please see Figure 8Specifically, a portion of the stretched portion of the elastic sheet 273 abuts against the inner wall of the slide groove 11, which is called the abutting section 2731. The portion of the stretched portion near the central axis 271 does not contact the inner wall of the slide groove 11, which is called the winding section 2732. The supporting section 2731 is far from the central axis 271, and the elastic force F' generated when it bends is directly applied to the inner wall of the slide groove 11. Since the supporting section 2731 is restricted by the slide groove 11, the elastic force F' it generates is mainly used to overcome elastic deformation, and the elastic force F' has little effect on the central axis 271. On the other hand, the winding section 2732 is close to the central axis 271 and does not contact the inner wall of the slide groove 11. When the elastic force F it generates acts on the central axis 271, it generates a downward pressure F1 and a lateral component force F2 extending along the slide groove 11. Since the degree of freedom of the central axis 271 is restricted by the slide groove 11, the lateral component force F2 cannot drive the central axis 271. Only the downward pressure F1 can drive the central axis 271 to slide along the slide groove 11. Therefore, the force that drives the central axis 271 to slide mainly comes from the winding section 2732. It should be noted that during the winding process of the elastic sheet 273, the dividing point between the supporting section 2731 and the winding section 2732 changes with the displacement of the central shaft 271. Only the winding section 2732 on the stretched part can drive the central shaft 271 to slide along the slide groove 11. Therefore, the downward pressure generated on the central shaft 271 will remain stable. In other words, when the tape resistor 20 in the storage bin 230 increases or decreases, the downward pressure applied by the pressure block 272 changes little, which can ensure that the pressure block 272 can smoothly drive the tape resistor 20 down along the limiting frame 231 and provide sufficient downward pressure to prevent the tape resistor 20 from flipping or tilting when the cutting cylinder 210 pushes the material.

[0038] The above-mentioned adhesive removal device 10 for tape and reel resistors has the following beneficial effects: 1. The conveyor belt 250 and the lifting cylinder 240 work together to stack the tape resistors to be degummed below the storage bin 230. The lifting cylinder 240 pushes the stacked tape resistors into the storage bin 230. The cutting cylinder 210 is responsible for pushing the resistors at the bottom of the storage bin 230 into the conveyor track 100. The product stacking and product loading processes are independent of each other and can be carried out simultaneously without interference, which helps to improve the loading efficiency of the products to be degummed. 2. The lifting cylinder 240 can fill the stacked tape resistors into the storage bin 230 from below. By replenishing the tape resistors into the storage bin 230, the problem of unstable feeding process caused by insufficient product quantity can be avoided.

[0039] 3. The elastic sheet 273 and the pressure block 272 work together to provide stable downward pressure on the tape resistor 20 in the storage bin 230. The pressure block 272 always presses down on the tape resistor 20, preventing the tape resistor 20 from jumping when the stop-cutting cylinder 210 pushes the material. This solves the problem of relying on the weight of the tape resistor 20 itself to maintain stable feeding in the existing feeding device. Even if there is only a single tape resistor 20 left in the storage bin 230, the stability of the feeding process can be guaranteed.

[0040] 4. The pressure block 272 contacts the topmost tape-and-reel resistor 20, which can prevent the product in the storage bin 230 from deflecting or tilting due to friction with the inner wall during descent, and further improve the stability of the feeding process.

[0041] Please see Figure 7 In one embodiment, an anti-deflection protrusion 13 is provided on the side of the pressure block 272 away from the bottom of the limiting frame 231. The anti-deflection protrusion 13 abuts against the inner wall of the limiting frame 231 and is used to prevent the pressure block 272 from rotating.

[0042] Please see Figure 8 In one embodiment, a clearance area 14 is provided at the position where the pressure block 272 is connected to the central shaft 271, and the rolled-up portion of the elastic sheet 273 is located within the clearance area 14.

[0043] Please see Figure 3 and Figure 6 In one embodiment, the feeding assembly 200 further includes a stacking bin 260 located below the storage bin 230. The stacking bin 260 has an inlet 261 at its connection point with the conveyor belt 250. A lifting cylinder 240 is located inside the storage bin 230, and a carrying plate 262 is provided on its output end, fitting against the inner wall of the storage bin 230. The stacking bin 260 provides a limit for the tape-and-reel resistors 20 falling from the conveyor belt 250, preventing the stacked tape-and-reel resistors 20 from collapsing. Preferably, the number of tape-and-reel resistors that the stacking bin 260 can hold is less than the number of tape-and-reel resistors that the storage bin 230 can hold.

[0044] Please see Figure 4 and Figure 6 In one embodiment, multiple elastic supports 120 are provided, and a spring 130 is provided between the elastic support 120 and the inner wall of the through hole 110. An inclined surface is provided on the side of the elastic support 120 facing the lifting cylinder 240. During the process of the lifting cylinder 240 pushing the stacked tape resistors 20 into the storage hopper 230, the tape resistors 20 push aside the elastic supports 120. After the tape resistors 20 enter the storage hopper 230, the elastic supports 120 pop out again and provide support at the bottom of the tape resistors 20. The elastic supports 120 and the through hole 110 cooperate to form a unidirectional feeding channel.

[0045] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
