Description

Technical Field

[0001] The invention relates to the technical field of tube-mounted chip burning and / or testing machines, and in particular to a feeding mechanism used for tube-mounted chip burning and / or testing machines. Background Art

[0002] A tube-mounted chip burning and / or testing machine is a machine used to perform burning and / or testing operations on chips.

[0003] The tube-mounted chip burning and / or testing machine has a chip conveying trough placed in front of its casing and arranged in an up-and-down direction for chip falling and conveying. Usually, in order to ensure that the chips can be stably dropped and conveyed along the chip conveying trough, the upper part of the chip conveying trough is slightly inclined toward the main body of the machine; a loading mechanism is provided above the chip conveying trough, and the loading mechanism is provided with a chip packaging tube insertion position for inserting a chip packaging tube.

[0004] The design of the existing loading mechanism for tube-mounted chip burning and / or testing machines is still not reasonable enough.

[0005] Comparative Document 1: The Chinese patent with the authorization announcement number CN208607650U and the name “An Improved Tube-mounted IC Burner” is an early technical solution, which has the following deficiencies (the 12-tube loading mechanism described in the patent is equivalent to the loading bin unit described in the technical solution of the present invention, and the socket is equivalent to the chip packaging tube insertion position described in the technical solution of the present invention):

[0006] (1) During the side-moving feeding process of the 12-tube feeding mechanism, the chip pins are easily deformed due to the force on the chip pins, resulting in a high failure rate of the burning operation. Fig.13 In the figure, the 12-tube feeding mechanism 30 is displaced from left to right in the direction shown in the figure. When a certain socket of the 12-tube feeding mechanism 30 is close to the chip conveying slot 02 but has not yet completely corresponded, it is easy for the weight of the entire tube chip to jump from the body part of the lowest chip of the socket to the weight of the entire tube chip to the lowest pin part of the chip, thereby causing the chip pin to be bumped and deformed. 31 in the figure is the force point where the chip pin bears the weight of the entire tube chip at this time.

[0007] (2) The 12-tube loading mechanism needs to occupy a large space in the left and right directions during the side-shift feeding process, and the space in the front and back directions of the tube-mounted chip burning and / or testing machine is not fully and reasonably utilized. Therefore, it is not conducive to the design of large-capacity sockets for the tube-mounted chip burning and / or testing machine. Fewer sockets require operators to frequently change tubes during the operation, making it difficult for operators to take care of other work, which also affects the efficiency of the tube-mounted chip burning and / or testing machine in burning operations.

[0008] (3) When performing the tube replacement operation, the operator needs to pull out the empty chip packaging tubes from each socket of the 12-tube loading mechanism one by one, and then confirm the front and back sides of the chip packaging tubes containing the chips to be burned one by one and insert them into each socket of the 12-tube loading mechanism. The operation process is cumbersome and time-consuming.

[0009] Comparative Document 2: Chinese patent application publication number CN 115924513A, entitled “A feeding device for a burning machine”, proposes a new technical solution to improve the working efficiency of the feeding device of a tube-mounted chip burning and / or testing machine, including (the tube material described in the patent is equivalent to the chip packaging tube described in the technical solution of the present invention, and the feeding track is equivalent to the chip conveying trough described in the technical solution of the present invention):

[0010] (1) A loading rack is used to accommodate pipes. Since the pipes are stacked up and down in the loading rack, the placement density is relatively large, which is conducive to increasing the capacity for placing pipes.

[0011] (2) Since the tubes are stacked in the vertical direction in the loading rack, in order to make each tube correspond to the feeding track in sequence, so that the chips in the tubes can fall into the feeding track in sequence for burning operations, a loading platform, a clamping mechanism, a flipping and moving mechanism, a pushing mechanism and a feeding track are added.

[0012] (3) Before the flipping mechanism drives the clamping mechanism to reach the feeding position, the mouth of the tube in the clamping mechanism is blocked by a baffle plate to prevent the chip from falling from the tube; when the flipping mechanism drives the clamping mechanism to reach the feeding position, the feeding track is docked with the feeding part, and the first telescopic component continues to apply pressure to the first clamping member to drive the second clamping member to compress the spring, so that the tube is connected to the feeding track, so that the chip can fall into the feeding track for burning operation; because the chip can only fall after the clamping mechanism reaches the feeding position and the feeding track is properly docked with the feeding part, the chip pins are prevented from being bumped and deformed.

[0013] However, the technical solution is still not perfect and has the following deficiencies:

[0014] (1) The loading rack does not have a fool-proof function. When the top and bottom of the pipe are reversed, it can still be placed in the loading rack as usual. This will cause operational failures. Operators need to be particularly cautious when performing pipe replacement operations.

[0015] (2) When performing the pipe replacement operation, the operator needs to confirm the front and back sides of the pipes one by one and then place them one by one from the top of the loading rack. The operation process is cumbersome and time-consuming, which reduces the convenience of operation.

[0016] (3) When the number of positions for accommodating pipes on the loading rack is designed to be too large, the height of the loading rack will exceed the height that the operator can normally operate. Therefore, the use of the loading rack to increase the capacity of the positions for accommodating pipes is relatively limited.

[0017] (4) Due to the addition of devices such as a loading platform, a clamping mechanism, a flipping mechanism, a pushing mechanism and a feeding track, many disadvantages are brought about, including: the devices occupy too much space, resulting in the space not being fully utilized, and more movable mechanisms increase the production cost and reduce the operational reliability.

[0018] (5) Devices such as baffles and springs that prevent chip pins from being deformed by bumps increase manufacturing costs, and more movable parts reduce operational reliability. Summary of the invention

[0019] In order to solve the deficiencies of the prior art, the invention objectives of the present invention include: providing a loading mechanism for a tube-mounted chip burning and / or testing machine, which is beneficial to improving the operating reliability, operating efficiency and operational convenience of the tube-mounted chip burning and / or testing machine.

[0020] For the convenience of description, the description of directions in the present invention is agreed upon: the chip conveying slot of the tube-mounted chip burning and / or testing machine extends upward in the direction of upward extension, and the opposite direction is downward; the direction in which the longitudinal notch of the chip conveying slot faces is the front, and the opposite direction is the rear; when the observer faces the front, the left-hand direction is the left, and the right-hand direction is the right.

[0021] The "front and rear directions" described in the present invention cannot be understood as being limited to the direction from directly front to directly rear. Similarly, the "left and right directions" described cannot be understood as being limited to the direction from directly left to directly right. The "front and rear directions" described cannot be understood as being limited to the direction from directly front to directly rear. Due to the inventive concepts and technical features disclosed in the present invention, the directional features thereof can still achieve the inventive objectives and beneficial effects of the present invention by angular deviations within a certain range. All such situations also fall within the scope of rights of the present invention.

[0022] For the convenience of description, the present invention makes a convention that the "row" mentioned in the present invention refers to the distribution in the left-right direction, and the "column" mentioned refers to the distribution in the front-back direction.

[0023] Technical concept: In view of the problems and shortcomings in the prior art, the applicant has found, based on long-term production practice and research, that if the chip packaging tube insertion position of the loading mechanism is displaced in the front-to-back direction so that the chip packaging tube insertion positions of each column correspond to the corresponding chip conveying grooves in sequence, when a chip packaging tube insertion position is adjacent to the chip conveying groove corresponding to the chip packaging tube, the bottom chip in the chip packaging tube at the chip packaging tube insertion position still bears the weight of the entire tube of chips with its main body, thus avoiding the chip pins from being bumped and deformed; and compared with Comparative Document 2, it can avoid adding more movable mechanisms, reduce the manufacturing cost, and improve the operation reliability.

[0024] See the present invention Fig.14 The upper bin unit 07 is displaced from left to right in the direction shown in the figure (actually from back to front in the device of the present invention). When the rightmost chip packaging tube insertion position in the figure is close to the chip conveying slot 02, and the chip 24 therein is about to fall into the chip conveying slot 02, the chip 24 still bears the weight of the entire tube of chips with its main body, thereby avoiding the pins of the chip 24 from being bumped and deformed.

[0025] In addition, this can also bring about many beneficial implementation effects, including:

[0026] (1) The chip packaging tube insertion position of the feeding mechanism of the present invention is displaced in the front-to-back direction, so that the chip packaging tube insertion positions of each column can correspond to the chip conveying slot in sequence, so that the tube-mounted chip burning and / or testing machine can design the chip packaging tube insertion positions to be distributed in two dimensions, the front-to-back direction and the left-to-right direction. This design makes more full and reasonable use of the space of the tube-mounted chip burning and / or testing machine, which is conducive to the design of large-capacity chip packaging tube insertion positions of the tube-mounted chip burning and / or testing machine, and improves the disadvantage of the prior art that the operator needs to frequently change the tube; and the design of the chip packaging tube insertion positions to be distributed in the left-to-right direction is conducive to the burning and / or testing of tube-mounted chips. The design of multiple chip conveying slots for the machine can make each column of chip packaging tube insertion positions correspond to a chip conveying slot respectively. The design of multiple chip conveying slots can significantly improve the efficiency of the burning operation, and is also conducive to the design of the tube-mounted chip burning and / or testing machine to support chip packaging tubes of various specifications. The combination of the chip packaging tube insertion positions in each column and the corresponding chip conveying slot can be independently designed to support a chip packaging tube of a certain specification. A tube-mounted chip burning and / or testing machine can be designed to support chip packaging tubes of various specifications, which can bring greater versatility to the tube-mounted chip burning and / or testing machine, as well as greater selection flexibility and convenience to users.

[0027] (2) In order to improve the disadvantage of the prior art in that the operation of changing tubes is cumbersome and to improve the convenience and efficiency of the tube changing operation, the applicant has made a new technical concept: the chip packaging tubes are grouped in a number (for example, 10) of chip packaging tubes, that is, the chip packaging tubes are stacked in the same direction and fixed (for example, wrapped and fixed with tape) as a whole. If the loading mechanism supports the placement and removal of chip packaging tubes packaged in groups, the convenience and efficiency of the tube changing operation can be significantly improved, and it is also beneficial to the sorting, counting, storage and recycling of chip packaging tubes. However, the prior art cannot support the placement and removal of chip packaging tubes packaged in groups, because if the loading mechanism of the prior art supports the placement and removal of chip packaging tubes packaged in groups, when the chip packaging tubes packaged in groups correspond to the chip conveying slot of the tube-mounted chip burning and / or testing machine, the chips in multiple chip packaging tubes will fall into the chip conveying slot at the same time, which will bring the following problems: .It cannot be guaranteed that the chips in multiple chip packaging tubes can fall neatly and orderly in the chip conveying trough. Even without the The problem is that since the thickness of different individual chips may be different, in the burning and testing station of the tube-mounted chip burning and / or testing machine, the front and back stacked chips cannot be accurately positioned to ensure accurate electrical connection of their pins. Even without the , In the above problem, assuming that the programmed chips are neatly stacked front and back in the chip conveying slot under the tube-mounted chip programming and / or testing station, the stacked chips still cannot automatically and accurately correspond to and fall into the inner cavity of each chip packaging tube of the discharging mechanism.

[0028] The chip packaging tube insertion position of the loading mechanism of the present invention is displaced in the front-to-back direction so that the chip packaging tube insertion positions of each column can correspond to the chip conveying slots in sequence. This technical concept enables each chip packaging tube in the group-packaged chip packaging tubes to correspond to the chip conveying slots in sequence, thereby avoiding the situation where chips in multiple chip packaging tubes fall into the same chip conveying slot at the same time. Therefore, it provides a prerequisite for the design of a tube-mounted chip burning and / or testing machine to support the placement and removal operations of the group-packaged chip packaging tubes.

[0029] In order to achieve the purpose of the invention and its inventive concept, the present invention provides the following technical solutions:

[0035] Technical Solution 5: A further technical solution based on Technical Solution 1: the upper bin base is provided with a conveyor belt device for reducing the friction force of the chip on it, the conveyor belt device corresponds to the lower part of the displacement trajectory of the chip packaging tube insertion position of the upper bin unit, and avoids the area corresponding to the chip conveying groove; the conveyor belt device includes a roller group and a conveyor belt, the roller group includes a plurality of rollers, the plurality of rollers are arranged along the direction of the displacement trajectory of the chip packaging tube insertion position with gaps between them, and are rotatably installed on the upper bin base in the axial direction to the left and right, and the conveyor belt is sleeved on the outer edges of the plurality of rollers.

[0061] Embodiment 1:

[0062] 1.Structural composition:

[0063] See also Figures 1 to 9 :

[0064] See also Figure 6 and Figure 7 , the five upper bin units 071 are respectively provided with two rows of chip packaging tube insertion positions 231, each row of chip packaging tube insertion positions 231 supports the insertion of four groups (in this example, 10 chip packaging tubes are stacked and packaged into one group) of chip packaging tubes 22; a spring sheet 101 is provided above the upper bin unit 071, and the spring sheet 101 includes a main body part and a spring tongue part, the main body part is fitted and installed on the upper end surface of the upper bin unit 071, and the spring tongue part is formed by the main body part extending in the left-right direction and bending downward, the The spring tongue portion is accommodated in the chip packaging tube insertion position 231 of the upper bin unit 071 and is close to the side wall; a guide plate 111 is provided above the spring sheet 101, and the guide plate 111 is provided with openings corresponding to the positions of each group of chip packaging tube insertion positions 231, and the openings tend to be open toward the outside to facilitate the operation of inserting the chip packaging tube 22; the guide plate 111 is fixedly connected to the upper bin unit 071 by screws, and the main body of the spring sheet 101 is pressed between the guide plate 111 and the upper bin unit 071.

[0065] See also Figure 8 and Fig. 9 The interior of the loading bin base 05 is arranged with four partition walls in the front-to-back direction, thereby forming five independent spaces.

[0066] See also Figures 1 to 5 The five loading bin units 071 are respectively guided in the front-to-back direction by the guide connecting parts composed of sliders 081 and guide rails 091 and installed in the five independent spaces of the loading bin base 05, so that each loading bin unit 071 can be displaced in the front-to-back direction relative to the loading bin base 05; the loading bin base 05 is provided with a photoelectric position detection device on both sides of each loading bin unit 071, which is used to detect whether the displacement of each loading bin unit 071 is in place, which is more accurate than judging whether the displacement is in place by the running time of the power device.

[0067] See also Figure 1 Five small screw motors 171 are fixedly installed behind the rear plate of the upper bin base 05. The screws used for power output of each small screw motor 171 are respectively engaged with each upper bin unit 071 for driving the upper bin unit 071 to move in the front-rear direction.

[0068] See also Fig. 9The upper surface of the bottom plate of the upper silo base 05 and corresponding to the displacement trajectory of the chip packaging tube insertion position 231 of the upper silo unit 071 is provided with a strip protrusion 191 for reducing the contact area of ​​the chip on the bottom plate of the upper silo base 05 and thereby reducing the friction force of the chip 24 on the bottom plate of the upper silo base 05.

[0069] The bottom plate of the upper bin base 05 has the function of preventing the chips 24 from falling to the area outside the chip conveying groove 02.

[0070] The left and right sides of the upper silo base 05 extend downward to form support arms 142 , and the lower ends of the support arms 142 are provided with mounting holes.

[0071] See also Figures 1 to 5 The loading bin base 05 is rotatably mounted on the two shaft seats of the front panel of the tube-mounted chip burning and / or testing machine through the mounting holes of its support arms 142 via two mounting shafts 122, thereby realizing the technical feature that the loading bin base 05 can be rotatably connected to the fixed part of the tube-mounted chip burning and / or testing machine.

[0072] In addition, a multi-link structure, a flexible body (eg, rubber body, etc.) structure, etc. may be used to realize the technical feature that the loading bin base 05 can be rotatably connected to the fixed part of the tube-mounted chip burning and / or testing machine.

[0073] The 10 chip conveying slots 02 of the tube-mounted chip burning and / or testing machine are arranged in the left-right direction on the front panel of the tube-mounted chip burning and / or testing machine, and the upper part thereof is slightly tilted backward to facilitate the stable falling and conveying of the chip 24 along the chip conveying slots 02.

[0074] The loading bin base 05 and its loading bin unit 071 can be rotated to a burning operation position or a tube changing operation position.

[0075] In the burn operation location, see Figure 1 , Figure 2 and Figure 5 The chip packaging tube insertion positions 231 of each column of the loading bin unit 071 are located above the 10 chip conveying slots 02, and the chip packaging tube insertion positions 231 of each column correspond to the direction of each chip conveying slot 02 and the position in the left and right direction, so that when the loading bin unit 071 moves in the front-back direction along the guide rail 091 in the loading bin base 05, the chip packaging tube insertion positions 231 of each row can correspond to the chip conveying slot 02 in sequence, and the chip 24 can fall from the chip packaging tube 22 of the chip packaging tube insertion position 231 to the corresponding chip conveying slot 02 for burning operation.

[0076] At the pipe replacement operation location, see Figure 3 and Figure 4The chip packaging tube insertion position 231 of the loading bin base 05 and its loading bin unit 071 is located at a position rotated to a certain angle relative to the burning operation position, so that the chip packaging tube 22 can be relatively flatly inserted into the chip packaging tube insertion position 231 when the tube replacement operation is performed, preventing the chip 24 from escaping from the chip packaging tube 22 to the area outside the chip conveying groove 02.

[0077] See also Figure 3 The motor bracket 16 is fixedly installed at the top of the casing 01, and the through-type screw motor 15 is rotatably connected to the motor bracket 16 through a rotating shaft. The large screw is dynamically engaged with the through-type screw motor 15, and its upper end is dynamically connected to the loading bin base 05 through a rotating shaft.

[0078] 2. Tube replacement process:

[0079] The operator inputs the tube changing operation instruction through the human-machine interactive interface provided by the tube-mounted chip burning and / or testing machine, and then the through-type screw motor 15 starts and drives the loading bin base 05 to rotate forward to the tube changing operation position with the two mounting shafts 122 as the fulcrum through the large screw (see Figure 3 and Figure 4 ), the tube-mounted chip burning and / or testing machine determines whether the loading bin base 05 is in place according to the proximity switch as a position sensor or according to the running time of the through-type lead screw motor 15; at this time, the direction of the chip packaging tube insertion position 231 is conducive to the relatively flat insertion of the chip packaging tube 22 used for loading, so as to prevent the chip 24 from accidentally falling out of the chip packaging tube 22 during the process of inserting the chip packaging tube 22 used for loading into the chip packaging tube insertion position 231; and at this time, the position of the loading bin unit 071 is slightly lower than that in the burning operation position, and its direction is toward the front, which is more convenient for the operator to perform the tube replacement operation.

[0080] The operator pulls out the empty chip packaging tube and inserts the chip packaging tube 22 containing the chip 24 to be burned into the chip packaging tube insertion position 231 (see Figure 3 ); Then the operator inputs the return operation instruction through the human-machine interactive interface provided by the tube-mounted chip burning and / or testing machine, and the five small screw motors 171 respectively drive the five loading bin units 071 to move up along the guide rails 091 to the uppermost area of ​​the loading bin base 05 (see Figure 4 ), the through-type screw motor 15 is started and drives the loading bin base 05 through the large screw to rotate backward to the burning operation position with the two mounting shafts 122 as the fulcrum (see Figure 5 ), the tube-mounted chip burning and / or testing machine determines whether the loading bin base 05 is in place based on the proximity switch serving as a position sensor or based on the running time of the through-type lead screw motor 15.

[0081] 3. Burning process:

[0082] See also Figure 5 Initially, the five upper bin units 071 are located in the rearmost area of ​​the upper bin base 05, and the chips 24 in the chip packaging tubes 22 at all chip packaging tube insertion positions 231 are prevented from falling by the bottom plate of the upper bin base 05 therebelow.

[0083] The operator inputs the burning operation instruction through the human-machine interactive interface provided by the tube-mounted chip burning and / or testing machine, and the five small lead screw motors 171 respectively drive the five loading bin units 071 to move forward along the guide rail 091, and the photoelectric sensor device detects whether the position of each loading bin unit 071 is in place; the chip packaging tube insertion position 231 of the front row of the loading bin unit 071 first corresponds to the chip conveying slot 02 below it, so the chip 24 falls to the corresponding chip conveying slot 02. Since the tube-mounted chip burning and / or testing machine is usually designed so that the pin surface of the chip 24 faces the front, the possibility of the chip pin being bumped and deformed due to the force on the chip pin is avoided during the process of the loading bin unit 071 moving forward to make the chip packaging tube insertion position 231 correspond to the chip conveying slot 02 and making the chip 24 fall to the corresponding chip conveying slot 02; the tube-mounted chip burning and / or testing machine detects that the chip 24 is below When the chip 24 is inserted into the chip packaging tube insertion position 231 of any upper bin unit 071, the burning process of the chip 24 is started; when the tube-mounted chip burning and / or testing machine detects that the chips 24 in the chip packaging tube insertion position 231 of the row of any upper bin unit 071 have all fallen into the chip conveying trough 02, the corresponding small lead screw motor 171 is started to drive the upper bin unit 071 to continue moving forward along the guide rail 091 to complete the burning process of the chips 24 in the chip packaging tube insertion position 231 of the next row; until the chips 24 in all the chip packaging tube insertion positions 231 of the five upper bin units 071 have all fallen into the chip conveying trough 02, the five small lead screw motors 171 respectively drive the five upper bin units 071 to the front end of the upper bin base 05 to facilitate the operator to perform the tube changing operation; then, the tube-mounted chip burning and / or testing machine sends a prompt sound prompt signal to prompt the operator to perform the tube changing operation.

[0086] This embodiment is different from Embodiment 1 in the following ways:

[0087] (1) A loading bin unit 07 is provided, and the loading bin unit 07 has 10 rows of chip packaging tube insertion positions. The loading bin unit 07 is installed by means of sliders 081 arranged in the front-to-back direction on both sides thereof and guide rails 091 respectively provided on the inner sides of the left and right walls of the loading bin base 05, so that the loading bin unit 07 can be displaced in the front-to-back direction relative to the loading bin base 05.

[0088] Two small lead screw motors 171 are fixedly installed behind the rear plate of the upper bin base 05. The lead screws used for power output of each small lead screw motor 171 are respectively engaged with the upper bin unit 07 for driving the upper bin unit 071 to move in the front-rear direction.

[0089] (2) A guide plate 11 is provided and installed above the upper bin unit 07.

[0090] (3) The bottom plate of the upper silo base 05 corresponds to the displacement trajectory of each column of chip packaging tube insertion position 231, and is respectively provided with a conveyor belt device for reducing the friction of the chip thereon. Each conveyor belt device includes a roller group and a conveyor belt 211. The roller group includes 9 rollers 201. The rollers 201 in the roller group are arranged in the front-to-back direction with gaps between them, and are axially rotatable in the left-right direction and installed on the bottom plate of the upper silo base 05. The conveyor belt 211 is sleeved on the outer edge of the roller group.

[0091] When the chip packaging tube insertion position 231 of the upper bin unit 07 is displaced in the front-to-back direction, the weight of the chips in each chip packaging tube falls on the conveyor belt 211, so the conveyor belt 211 is displaced accordingly, and each roller 201 rotates accordingly, thereby avoiding direct friction of the chips against the bottom plate of the upper bin base 05.
